ePub - Malignant gastric outlet obstruction (GOO) is a condition characterized by blockage or narrowing where the stomach empties its contents into the small intestine due to primary malignant tumors or metastatic diseases. This condition leads to various symptoms such as nausea, vomiting, abdominal pain, and weight loss. To manage malignant GOO, different treatment options have been employed, including surgical gastrojejunostomy (SGJ), gastroduodenal stenting (GDS) using self-expandable metallic stent (SEMS), and endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ). This review focuses on comparing the clinical outcomes of endoscopic stenting (GDS and EUS-GJ) with SGJ for malignant GOO. Studies have shown that GDS with SEMS provides comparable clinical outcomes and safety for the palliation of obstructive symptoms. The choice between covered and uncovered SEMS remains controversial, as different studies have reported varying results. EUS-GJ, performed via endoscopic ultrasound guidance, has shown promising efficacy and safety in managing malignant GOO, but further studies are needed to establish it as the primary treatment option. Comparative analyses suggest that GDS has higher recurrence and reintervention rates compared to EUS-GJ and SGJ, with similar overall procedural complications. However, bleeding rates were lower with GDS than with SGJ. Randomized controlled trials are required to determine the optimal treatment approach for malignant GOO.

/Aims: Endoscopic channels are difficult to clean and can cause infection transmission. We examined the effectiveness of a newly developed channel-cleaning ball brush (BB), which is sucked into the endoscopic channel and scrapes and cleans the lumen as it passes through.
Methods
The upper and lower gastrointestinal endoscopes used for patient examinations were randomly selected as the conventional brush (CB) or BB group. After manual cleaning, the presence or absence of carbohydrates, proteins, adenosine triphosphate, and hemoglobin was assessed.
Results
Fifty-six and 58 endoscopes were cleaned with the CB and BB, respectively. Carbohydrate and protein were detected in one (1.8%) and two endoscopes (3.4%) in the CB and BB groups, respectively (p=1.000). Hemoglobin was observed in one (1.8%) and three endoscopes (5.2%) in the CB and BB groups, respectively (p=0.636). The adenosine triphosphate levels were 10.6±15.9 and 12.5±14.3 relative light units in the CB and BB groups, respectively (p=0.496). Twenty-seven (48.2%) and 19 (32.8%) endoscopes were positive for microbial cultures in the CB and BB groups, respectively (p=0.136).
Conclusions
The efficacy of BB was not significantly different from that of CB in the endoscopic channel-cleaning process. -

- Background
/Aims: The recommendations on the time interval between pre-cleaning and reprocessing of endoscopes differ in international guidelines, with a low level of evidence. The aim of this study was to investigate the influence of postponing reprocessing on the reprocessing quality after pre-cleaning the flexible endoscopes.
Methods
We reprocessed 124 standardized test tubes simulating endoscope channels after soiling and contamination and determined the reprocessing performance. In addition, we examined contaminated gastroscopes, colonoscopes, and bronchoscopes. The duration of interim storage after pre-cleaning was 16 h for 100 test tubes and up to 24 h for 18 endoscopes. We determined the residual protein content and germ load as markers for cleaning and disinfection performance. In addition, we determined biofilm formation by photometry of crystal violet staining.
Results
All test tubes and flexible endoscopes showed residual protein content and germ load significantly below legally prescribed threshold values, independent of the interval between pre-cleaning and reprocessing.
Conclusions
Our findings indicate that flexible endoscopes could be stored overnight after pre-cleaning without any influence on the quality of reprocessing. While ensuring patient safety, this could simplify logistical processes and enable cost savings. -

- Background
/Aims: Endoscopic ultrasonography (EUS)-guided tissue acquisition requires a long learning curve. We aimed to compare the skill maturation curves between fine needle aspiration (FNA) and biopsy (FNB) for tissue acquisition.
Methods
The initial 60 procedures performed by the trainee endosonographer (30 FNA vs. 30 FNB) were consecutively enrolled. The difference in procedure performance was compared between the two groups. Learning curves were assessed. Twenty additional cases were subsequently enrolled to assess the consistency of performance in the FNB group.
Results
The FNB group acquired larger tissue samples (2.35 vs. 0.70 mm2; p<0.001) with lower blood content (p=0.001) and higher tissue quality (p=0.017) compared with the FNA group. In addition, the FNB group required less needle pass to establish a diagnosis (2.43 vs. 2.97; p=0.006). A threshold diagnostic sensitivity of ≥80% was achieved after performing 10 FNB procedures. The number of needle passes significantly decreased after conducting 20 FNB procedures (1.80 vs. 2.70; p=0.041). The diagnostic sensitivity and number of needle passes remained the same in the subsequent FNB procedures. By contrast, this skill maturation phenomenon was not observed after performing 30 FNA procedures.
Conclusions
In EUS-guided tissue acquisition, the FNB needle was more efficient and thus shortened the learning curve of EUSguided tissue acquisition in trainee endosonographers. -

- Background
/Aims: Unsedated transnasal esophagogastroduodenoscopy (EGD) is affected by a poor scope lens-cleaning function. We have previously reported good, albeit limited, effects of an oolong tea washing solution; here, we evaluated the effectiveness of a 5% lens cleaning solution for cleaning an EGD lens.
Methods
Five percent lens cleaning solution (C), 5% dimethicone solution (D), and distilled water (W) were prepared. Study I: Lenses were soiled with pork grease, washed with each washing solution, and their image quality was judged. Study II: Patients (n=996) scheduled for transnasal EGD were randomly assigned to the C- or W-group. Lens cleanliness level, washing solution volume used, and endoscopist stress due to lens contamination were determined.
Results
Study I: The image quality of the lenses washed with (C) was significantly superior. (D) was clinically unsuitable because of spray nozzle clogging. Study II: Lens cleaning in the C-group was significantly superior (p<0.0001) and the solution volume required was significantly reduced (p<0.0001), while endoscopist stress was also lower (p<0.0001).
Conclusions
For transnasal small-caliber EGD, the present 5% lens cleaning solution provided good visibility. It features a high detergency level and is simple to formulate for therapeutic endoscopy applications, such as endoscopic submucosal dissection.

Abstract
PDFPubReaderePub
- The area of endoscopic application has been continuously expanded since its introduction in the last century and the frequency of its use also increased stiffly in the last decades. Because gastrointestinal endoscopy is naturally exposed to diseased internal organs and contact with pathogenic materials, endoscopy mediated infection or disease transmission becomes a major concern in this field. Gastrointestinal endoscopy is not for single use and the proper reprocessing process is a critical factor for safe and reliable endoscopy procedures. What needed in these circumstances is a practical guideline for reprocessing the endoscope and its accessories which is feasible in the real clinical field to guarantee acceptable prevention of pathogen transmission. This guideline contains principles and instructions of the reprocessing procedure according to the step by step. And it newly includes general information and updated knowledge about endoscopy-mediated infection and disinfection. Multiple societies and working groups participated to revise; Korean Association for the Study of the Liver, the Korean Society of Infectious Diseases, Korean College of Helicobacter and Upper Gastrointestinal Research, the Korean Society of Gastroenterology, Korean Society of Gastrointestinal Cancer, Korean Association for the Study of Intestinal Diseases, Korean Pancreatobiliary Association, the Korean Society of Gastrointestinal Endoscopy Nurses and Associates and Korean Society of Gastrointestinal Endoscopy. Through this cooperation, we enhanced communication and established a better concordance. We still need more researches in this field and fill up the unproven area. And our guidelines will be renewed accordingly.

Abstract
PDFPubReaderePub
- Background
/Aims: Non-invasive tissue sampling from the lower intra-abdominal and pelvic cavity is challenging. The role of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in this situation is not well-established because of the limitations of the curved linear-array echoendoscopy-EUS for colonic insertion. The aim of this study was to report our institutional experience of transcolonic EUS-FNA using forward-viewing therapeutic linear echoendoscopy-EUS (FV-EUS) in combination with fluoroscopic guidance.
Methods
Medical records of 13 patients who underwent transcolonic EUS-FNA of extracolonic lesions using FV-EUS in combination with fluoroscopic guidance at Aichi Cancer Center Hospital, Nagoya, Japan from June 2015 to November 2018 were retrospectively reviewed.
Results
Using FV-EUS under fluoroscopic guidance, the FNA procedure could be performed successfully in all patients (100% technical success), with a median procedure time of 31 minutes. The sensitivity, specificity, and accuracy of EUS-FNA for detecting malignant lesions in this study were 91%, 100%, and 92%, respectively. There were no adverse events associated with the EUS-FNA procedure.
Conclusions
FV-EUS in combination with fluoroscopic guidance is an easy, safe, and effective technique for FNA of extracolonic lesions in the lower abdomen. -

- Background
/Aims: Altered anatomy is a challenge in endoscopic retrograde cholangiopancreatography (ERCP) for patients with Billroth II anastomosis. In this study, we investigated the overall success and role of endoscopist experience.
Methods
Data of patients who underwent ERCP between 2014 and 2018 after a previous Billroth II operation were retrieved retrospectively from 2 tertiary ERCP centers. The procedures were performed by 2 endoscopists with different levels of experience. Clinical success was defined as extraction of the stone, placement of a stent through a malignant stricture, and clinical and laboratory improvements in patients.
Results
Seventy-five patients were included. The technical success rate was 83% for the experienced endoscopist and 75% for the inexperienced endoscopist (p=0.46). The mean (±standard deviation) procedure time was 23.8±5.7 min for the experienced endoscopist and 40.68±6.07 min for the inexperienced endoscopist (p<0.001). In total, 3 perforations (4%) were found. The rate of afferent loop perforation was 6.25% (1/16) for the inexperienced endoscopist and 0% (0/59) for the experienced endoscopist (p=0.053).
Conclusions
ERCP in patients who had undergone Billroth II gastrectomy was time consuming for the inexperienced endoscopist who should beware of the unique adverse events related to ERCP in patients with altered anatomy. -

- Background
/Aims: Poor suction ability through a narrow working channel prolongs esophagogastroduodenoscopy (EGD). The aim of this study was to evaluate suction with a new ultrathin endoscope (EG-580NW2; Fujifilm Corp.) having a 2.4-mm working channel in clinical practice.
Methods
To evaluate in vitro suction, 200 mL water was suctioned and the suction time was measured. The clinical data of 117 patients who underwent EGD were retrospectively reviewed on the basis of recorded video, and the suction time was measured by using a stopwatch.
Results
In vitro, the suction time with the EG-580NW2 endoscope was significantly shorter than that with the use of an ultrathin endoscope with a 2.0-mm working channel (EG-580NW; mean ± standard deviation, 22.7±1.1 seconds vs. 34.7±2.2 seconds; p<0.001). We analyzed the total time and the suction time for routine EGD in 117 patients (50 in the EG-580NW2 group and 67 in the EG-580NW group). In the EG-580NW2 group, the total time for EGD was significantly shorter than that in the EG-580NW group (275.3±42.0 seconds vs. 300.6±46.5 seconds, p=0.003). In the EG-580NW2 group, the suction time was significantly shorter than that in the EG-580NW group (19.2±7.6 seconds vs. 38.0±15.9 seconds, p<0.001).
Conclusions
An ultrathin endoscope with a 2.4-mm working channel considerably shortens the routine EGD time by shortening the suction time, in comparison with an endoscope with a 2.0-mm working channel. -

Previous studies reported that ultrathin endoscope (UE) provides endoscopic guidance during insertion of a self-expanding metal stent (SEMS) without fluoroscopic monitoring in patients with upper gastrointestinal stenosis (benign or malignant) or postoperative esophageal leakage. According to the type of SEMS and level of the stenosis, the technique of the procedure is variable. Herein, we report a patient who underwent placement of a distal release esophageal SEMS to treat an esophagogastric anastomotic stricture via retroflexed UE.

Abstract
PDFPubReaderePub
Endoscopy-related infections are important contributors to nosocomial infections. Endoscope reprocessing according to standard guidelines ensures high-level disinfection and prevents endoscopy-related infections. Microbiological surveillance may help in monitoring the effectiveness of gastrointestinal endoscope disinfection. The process involves microbial cultures and non-culture methods such as bioburden assays, adenosine triphosphate (ATP) bioluminescence, and quantitative polymerase chain reactions (PCRs). Surveillance culturing to monitor endoscopes after reprocessing has been recommended by a majority of organizations. Bioburden assays, ATP bioluminescence, and quantitative PCRs provide rapid and reliable measures. Each institution will have to try to establish its own surveillance guidelines.

Abstract
PDFPubReaderePub
A duodenoscope has a very complex structure that contains many small parts which make reprocessing more challenging. The difficulty in cleaning duodenoscopes contributes to a higher risk of infection than that of conventional gastrointestinal endoscopes. However, a duodenoscope shares similar disinfection process with other gastrointestinal endoscopes. Recent outbreaks of carbapenem-resistant Enterobacteriaceae (CRE) infections associated with duodenoscopes used for endoscopic retrograde cholangiopancreatography procedures have raised many concerns worldwide. Duodenoscope-associated infections involving CRE or other multidrug-resistant bacteria pose a great threat to patients undergoing procedures using duodenoscopes and should be dealt with a great concern. Updated guidelines regarding cleaning and disinfection of duodenoscope needs to be developed urgently to prevent transmission of infection and ensure patient safety. Meanwhile, healthcare staff should pay special attention to thorough cleaning and disinfection of duodenoscopes.

Abstract
PDFPubReaderePub
Based on the unexpected Middle East respiratory syndrome (MERS) outbreak in Korea, it was established that the virus can spread easily, MERS exposure in hospitals carries an extreme risk for infection as well as mortality, and the sharing of information was essential for infection control. Although the incidence of exogenous infections related to contaminated endoscopes is very low, the majority of published outbreaks have been caused by various shortcomings in reprocessing procedures, including insufficient training or awareness. Ever since the inauguration of "
Clinical Endoscopy " as an English-language journal of the Korean Society of Gastrointestinal Endoscopy in 2011, it has published several articles on disinfection of the endoscope and its accessories. Many Science Citation Index journals have also emphasized high-level disinfection of the gastrointestinal endoscope. Many papers have been produced specifically, since the outbreak of carbapenem-resistant Enterobacteriaceae in 2013. The recent review papers concluded that quality control is the most important issue among all the aspects of procedural care, including the efficiency of the gastrointestinal endoscopy unit and reprocessing room. Thorough reprocessing of endoscopes using high-level disinfection and sterilization methods may be essential for reducing the risk of infection.-

Abstract
PDFPubReaderePub
Advantages of direct peroral cholangioscopy (POC) using an ultraslim endoscope include use of conventional endoscopy equipment, operation by a single endoscopist, and superior image quality of the biliary tree with easy application of enhanced endoscopy and a large working channel. The major diagnostic indications of this system are an evaluation of biliary strictures, filling defects, or unclear findings on cholangiogram or other imaging studies. Therapeutic application using a direct POC system can be broadened by a larger working channel. However, direct POC is difficult to apply in patients with a narrow diameter bile duct, far distal common bile duct lesion, or failed anchoring of the scope with accessories. An air embolism is a rare complication of direct POC but can be a fatal problem. Cholangitis can also occur during or after the procedure. Use of a CO2 system instead of room air during the POC procedure and administration of antibiotics before and after the procedure are strongly recommended. Continuous development of specialized endoscopes and accessories is expected to facilitate the diagnostic and therapeutic roles of direct POC.

Abstract
PDFPubReaderePub
Background/Aims Endoscopic management of upper gastrointestinal obstruction is safe and feasible. However, its technical and clinical success rate is about 90%, which is primarily due to inability to pass a guide-wire through the stricture. The aim of this study was to evaluate the usefulness of an ultrathin endoscope for correct placement of guide wire to avoid technical failure in upper gastrointestinal obstruction.
Methods Retrospective assessment of ultrathin endoscope to traverse the stenosis of the upper gastrointestinal tract in technically difficult cases was performed. Technical and clinical success rates and immediate complications were analyzed.
Results Nine cases were included in this study (eight cases of stent insertion and one case of balloon dilatation). Technical success was achieved in all of the patients (100%) and oral feeding was feasible in all of the cases (100%). Immediate complications, such as migration, perforation, and hemorrhage, did not develop in any of the cases.
Conclusions Ultrathin endoscope-assisted method for upper gastrointestinal obstruction is potentially safe and useful to avoid technical failure.

Background/Aims Patients undergoing Billroth II (B II) gastrectomy are at higher risk of perforation during endoscopic retrograde cholangiopancreatography (ERCP). We assessed the success rate and safety of forward-viewing endoscopic biliary intervention in patients with B II gastrectomy.
Methods A total of 2,280 ERCP procedures were performed in our institution between October 2008 and June 2011. Of these, forward-viewing endoscopic biliary intervention was performed in 46 patients (38 men and 8 women with B II gastrectomy). Wire-guided selective cannulations of the common bile duct using a standard catheter and guide wire were performed in all patients.
Results The success rate of afferent loop entrance was 42 out of 46 patients (91.3%) and of biliary cannulation after the approach of the papilla was 42 out of 42 patients (100%). No serious complications were encountered, except for one case of small perforation due to endoscopic sphincterotomy site injury.
Conclusions When a biliary endoscopist has less experience and patient volume is low, ERCP with a forward-viewing endoscope is preferred because of its ease and safety in all patients with prior B II gastrectomies. Also, forward-viewing endoscope can be used to improve the success rate of biliary intervention in B II patients.

Background/Aims Three-dimensional (3D) imaging is gaining popularity and has been partly adopted in laparoscopic surgery or robotic surgery but has not been applied to gastrointestinal endoscopy. As a first step, we conducted an experiment to evaluate whether images obtained by conventional gastrointestinal endoscopy could be used to acquire quantitative 3D information.
Methods Two endoscopes (GIF-H260) were used in a Borrmann type I tumor model made of clay. The endoscopes were calibrated by correcting the barrel distortion and perspective distortion. Obtained images were converted to gray-level image, and the characteristics of the images were obtained by edge detection. Finally, data on 3D parameters were measured by using epipolar geometry, two view geometry, and pinhole camera model.
Results The focal length (
f ) of endoscope at 30 mm was 258.49 pixels. Two endoscopes were fixed at predetermined distance, 12 mm (d 12). After matching and calculating disparity (v2-v1 ), which was 106 pixels, the calculated length between the camera and object (L ) was 29.26 mm. The height of the object projected onto the image (h ) was then applied to the pinhole camera model, and the result ofH (height and width) was 38.21 mm and 41.72 mm, respectively. Measurements were conducted from 2 different locations. The measurement errors ranged from 2.98% to 7.00% with the current Borrmann type I tumor model.Conclusions It was feasible to obtain parameters necessary for 3D analysis and to apply the data to epipolar geometry with conventional gastrointestinal endoscope to calculate the size of an object.

Background/Aims Since endoscopes are reusable apparatus classified as semicritical item, thorough reprocessing to achieve high-level disinfection is of utmost importance to prevent spread of infection. To improve disinfection efficacy and safety, disinfectants and endoscope reprocessors are continuously evolving. This study aimed to compare the efficacy of the combination of polyhexamethylenebiguanide hydrochloride-alkyldimethylbenzylammonium chloride (PHMB-DBAC) and orthophthalaldehyde (OPA) used respectively in ultrasonographic cleaning incorporated automated endoscope reprocessors: COOLENDO (APEX Korea) or OER-A (Olympus Optical).
Methods A total of 86 flexible upper endoscopes were randomly reprocessed with either COOLENDO/PHMB-DBAC or OER-A/OPA. Culture samplings were done at two sites (endoscope tip and working channel) which were later incubated on blood agar plate. Bacterial colonies were counted and identified.
Results The culture-positive rate at the endoscope tip and working channel was 0% and 2.33% for COOLENDO/PHMB-DBAC and 4.65% and 0% for OER-A/OPA.
Staphylococcus hominis was cultured from one endoscope reprocessed with COOLENDO/PHMB-DBAC andPseudomonas putida was isolated from two endoscopes reprocessed with OER-A/OPA.Conclusions The reprocessing efficacy of COOLENDO/PHMB-DBAC was non-inferior to that of OER-A/OPA (
p =0.032; confidence interval, -0.042 to 0.042). During the study period, significant side effect of PHMB-DBAC was not observed.-

- A duodenal diverticulum is most common in the medial aspect of the second portion of the duodenum and rarely causes symptoms. An obstruction, bleeding, perforation, jaundice and pancreatitis are uncommon complications of a duodenal diverticulum. Bleeding from the periampullary diverticulum should be considered in the diagnosis of a patient who presents with upper gastrointestinal bleeding of unknown origin. The second portion of the duodenum is sometimes difficult to observe entirely from the tangent line with the use of a forward-viewing endoscope. The diagnosis and treatment of periampullary diverticular bleeding may be achieved more easily by use of a side-viewing endoscope. We report here a case of narrow opened periampullary diverticular bleeding diagnosed by the use of a side-viewing endoscope with difficulty. (Korean J Gastrointest Endosc 2009; 38:275-278)

- Colonic pseudolipomatosis is a benign condition that is caused by mechanical trauma during an endoscopic procedure or by disinfectant colitis. It is characterized by empty vacuoles that are similar to the adipocyte in the lamina propria on histology and whitish plaques that are seen endoscopy. The prevalence of pseudolipomatosis is relatively low due to the lack of clinical experience and there have been no Korean reports about colonic pseudolipomatosis with the typical endoscopic findings. We report here on three cases of colonic pseudolipomatosis that was caused by endoscope disinfectant (paracetic acid). Typical whitish plaques were observed during the colonoscopic procedures in all 3 cases. In one case, whitish plaques appeared before our eyes immediately after the sudden appearance of whitish foamy fluid when the water button was depressed. H&E stain revealed empty vacuoles in the lamina propria and immunohistochemical staining showed no expression of CD31, CD34 and s-100. There were no symptoms related to these lesions in our cases.

- Peroral cholagioscopy is a good procedure that permits direct visualization of the biliary tree and target biopsies of lesions. However, peroral cholangioscopy with a mother- baby system requires two experienced endoscopists, and the procedure remains time consuming and expensive and the apparatus is easily broken. Therefore, an easier technique to get direct visual examination of the biliary tree is needed. Direct peroral cholangioscopy (direct POC) with using an ultra-slim upper endoscope was performed in two patients after endoscopic stone removal for diagnosing their biliary stricture. One patient had wire-guided direct POC performed and the patient was diagnosed benign biliary stricture on the proximal CBD after forcep biopsy. Another patient had overtube-assisted direct POC performed and that patient was found to have a polypoid lesion at the bifurcation. Future advances in endoscope development, as well as specifically designed accessories, are expected to increase its clinical utility. Korean J Gastrointest Endosc 2007;35: 373-377)

- Bezoars are persistent concretions of indigestible material that are usually found in the stomach. With the significant development of endoscopic techniques, many authors have reported the removal of bezoars using methods such as endoscopic forceps, snares, electrohydraulic lithotripsy, laser. However, there are no reports of using argon plasma to remove a bezoar in Korea. Argon plasma coagulation is a non-contact electrosurgical technique, which is an inexpensive, easily learned, and effective method in gastrointestinal endoscopy. In addition, this method is associated with a decreased risk of perforation and tissue damage by maintaining a controllable depth of coagulation. We report a 71-year-old man with a 11×11×8 cm sized huge gastric phytobezoar found by endoscopy. The bezoar was broken into pieces using the argon plasma coagulator. Endoscopic forceps and a basket were then used to crush and extract its fragments. The bezoar was removed safely without any complications. We report this case with a review of the relevant literature.

- Background
/Aims: The aim of this study was to compare the patient's satisfaction and tolerance of transnasal (TN) and transoral (TO) endoscopy prospectively. Methods: 120 patients were assigned to undergo TN (age: 49.5, M：F=65：55) or TO (age: 47.4, M：F=63：57) endoscopy according to their wishes. Results: The patients' satisfaction was higher in the TN group than in the TO group (8.45 vs. 4.95, p＜0.05). The degree of choking sensation, nausea, and throat soreness was lower in the TN group than the TO group. There was no difference in endoscopists' satisfaction between the two groups. The duration for TN was longer than for TO. Epistaxis and nasal pain were the common complications in the TN group. All complications were mild and were relieved spontaneously. An endoscopic examination could be completed in all patients in the TO group. In the TN group, examination failure was quite common in the early phase but the incidence decreased with increasing experience. It took the experience of at least 20 cases for the endoscopist to adapt to the TN route. Conclusions: TN endoscopy is believed to be a comfortable and safe procedure for improving the patients' satisfaction and for reducing the level of inconvenience.

/Aims: Capsule endoscope (CE) is a new method of investigating entire small bowel (SB). Some reported that current battery time was sufficient for observing entire SB, but others reported negatively. The aims of this study were to determine the factors influencing the entire SB transit rate. Methods: From Sep. 2002 to Aug. 2003, CE was performed in 197 cases and they were devided into complete/incomplete transit according to getting ileocecal valve image within battery time. sixteen cases were excluded due to anatomical abnormality or artificial procedure. one hundred eighty one cases were analyzed with multiple logistic regression. Results: The complete SB transit rate was 63.5%. Mean battery time was 7½ hrs. Gastric transit time (GTT) was significantly shorter in complete group than in incomplete group but the other factors (age, sex, preparation, symptom) were not significant. Mean small bowel transit time in complete group was 4½ hrs and ranged from 1 to 8 hrs. In incomplete group (66 cases), 2 cases were reached to distal jejunum, 11 cases to proximal ileum, and the other 53 cases to distal ileum. Conclusions: Complete SB transit rate of CE was 63.5% in the 181 cases under current battery time. GTT was the only significant factor influencing gastrointestinal transit rate of CE.

/Aims: We aimed to evaluate the long-term outcome of patients with MALT lymphoma in respect to various treatment modalities and clinicopathologic characteristics, including endoscopic findings. We also tried to deduce suitable strategic guideline to treat MALT lymphoma. Methods: We retrospectively studied 55 patients (24 males and 31 females) aged 23 to 74 years who had primary low-grade gastric MALT lymphoma that were diagnosed between May 1992 and August 2002. Results: The majority of endoscopic findings showed lesions with ulceration or with color and surface change of mucosa. All but one was H. pylori positive when tested. Treatment modalities included anti H. pylori treatment, radiation, surgery and/or chemotherapy. Eradication was successful in all the 29 patients associated with H. pylori infection. Complete remission was obtained in 24 patients (82.8%). Only one patient suffered a relapse after 28 months during the follow up (2∼74 months). The duration to reach complete remission was 12 months (85 percentile, 2∼33 months). Six patients showed complete remission with radiation therapy. Two of them were H. pylori treatment failure cases. One of 14 patients treated by surgery displayed relapse during follow-up (12∼120 months). Endoscopically, the ulcerative and/or the protruding type showed unfavorable response to anti H. pylori treatment. Conclusion: H. pylori eradication alone should be considered as an initial treatment for MALT lymphoma and radiation therapy could be preferred in patients with no evidence of H. pylori infection or who do not response to H. pylori eradication therapy 12 months after successful eradication.

/Aims: Safety of endoscopic procedures has been a major issue over the last 10 years. Most endoscopy units use 2% glutaraldehyde and automated endoscope reprocessors (AERs) for disinfecting gastrointestinal endoscopes. We attempted an in-use evaluation of the current reprocessing procedures. Methods: Thirty flexible endoscopes were randomly collected just after upper endoscopic examinations and were disinfected using 2% glutaraldehyde in an AER. Cultures were taken from biopsy channels (S-l), tip of the insertion tubes (S-2), umbilical cords (S-3), and angulation knobs (S-4). Results: In 63,3% (19/30) of endoscopes, there was no microbial contamination after disinfection procedures. The culture positive rates of S-l, S-2, S-3, and S-4 samples were 20,0%, 0.0%, 3.3%, and 20.0%, respectively. Microorganisms of 13 species were identified, but there was no pathogen related with reported infectious complications after endoscopic procedures. Conclusions: Current disinfection procedure using 2% glutaraldehyde and an AER appears to be very effective in decontaminating patient-used endoscopes. Low level microbial contamination of endoscopes after conventional reprocessing methods may not impose great risk on patients. (Korean J Gastrointest Endosc 2001;22:393-398)

- Background
/Aims: Expandable stents were inserted for temporary decompression of the colorectum before single-stage surgery or for palliation. The aim of this study was to evaluate the usefulness of a self-expandable nitinol stent, which can be placed through the working channel of an endoscope, for treatment of malignant colorectal obstructions. Methods: From May 2000 to April 2001, twenty patients (eleven female, nine male, aged 39~81 years) with malignant colorectal obstructions were treated for relief from the obstructions with endoscopically guided intubation of a expandable nitino stent through the working channel of an endoscope. Of twenty patients, thirteen underwent placement of the stent for presurgical decompression; seven, for palliative decompression. Results: The site of obstructions were on the rectum (n=8), sigmoid colon (n=6), descending colon (n=2), transverse colon (n=3) and ascending colon (n=1). Stent placenment was successful in 18 (90%) of the 20 patients. Failure occurred in two patients with long and tortuous lesions involving hepatic flexure or splenic flexure. All patients tolerated placement of the stent well, with no procedure-related complications. Is patients with successful placement of the stent, symptoms of obstruction resolved within 72 hours. Twelve patients underwent the formal bowel preparation and elective single-stage surgery without complications 4~7 days after stent placement. In six patients, the stents provided palliative decompression of the colorectum. There was stent migration in two patients during follow-up. Conclusions: placement of a self-expandable nitinol stent through the working channel of an endoscope is technically feasible and safe. Stent placement allowed patients with malignant colorectal obstruction to undergo single-stage surgery in cases of operable disease and to provide palliative decompression in cases of inoperable disease.
