Unilateral Versus Bilateral Biliary Drainage for Post-Transplant Anastomotic Stricture: Jin Ho Choi, Woo Hyun Paik; Clin Endosc 2020;53(3):255-260. Published online May 22, 2020; DOI: https://doi.org/10.5946/ce.2020.079

Abstract PDF PubReader ePub

Living donor liver transplantation is the most common type of liver transplantation in Asia. Post-transplant biliary stricture is frequent in living donor liver transplantation, and endoscopic management is considered to be the treatment of choice. However, endoscopic management is still challenging in patients who undergo right lobe living donor liver transplantation because of the anatomical alteration. In this article, we reviewed the recently updated results for proper endoscopic biliary drainage in post-living donor liver transplantation anatomical biliary stricture and compared unilateral and bilateral drainage.

Abstract PDF PubReader ePub

Anastomotic stricture (AS) is one of the complications of liver transplantation (LT) and can occur in up to 40% of living-donor LTs. Endoscopic management has become the first-line treatment of AS, and multiple plastic stents insertion has been mainly used in the past. Recently, many treatments utilizing fully covered self-expandable metal stents (cSEMSs) have been attempted, and results showing adequate treatment outcome have been reported. In this review, we look into the treatment performance and cautionary steps needed when using cSEMS as a treatment for AS.

Magnetic Compression Anastomosis for the Treatment of Post-Transplant Biliary Stricture: Sung Ill Jang, Jae Hee Cho, Dong Ki Lee; Clin Endosc 2020;53(3):266-275. Published online May 29, 2020; DOI: https://doi.org/10.5946/ce.2020.095

Abstract PDF PubReader ePub

A number of different conditions can lead to a bile duct stricture. These strictures are particularly common after biliary operations, including living-donor liver transplantation. Endoscopic and percutaneous methods have high success rates in treating benign biliary strictures. However, these conventional methods are difficult to manage when a guidewire cannot be passed through areas of severe stenosis or complete obstruction. Magnetic compression anastomosis has emerged as an alternative nonsurgical treatment method to avoid the mortality and morbidity risks of reoperation. The feasibility and safety of magnetic compression anastomosis have been reported in several experimental and clinical studies in patients with biliobiliary and bilioenteric strictures. Magnetic compression anastomosis is a minimally traumatic and highly effective procedure, and represents a new paradigm for benign biliary strictures that are difficult to treat with conventional methods.

Abstract PDF PubReader ePub

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.

Methods that Assist Traction during Endoscopic Submucosal Dissection of Superficial Gastrointestinal Cancers: A Systematic Literature Review: Georgios Tziatzios, Alanna Ebigbo, Stefan Karl Gölder, Andreas Probst, Helmut Messmann; Clin Endosc 2020;53(3):286-301.

Abstract PDF Supplementary Material PubReader ePub

Endoscopic submucosal dissection (ESD) is a well-established method for the treatment of early-stage gastrointestinal neoplasms. Adequate submucosal exposure is one of the most significant factors related to an effective and safe dissection. The aim of this systematic review was to evaluate the effcacy and safety of various methods that assist traction during ESD of precancerous and earlystage neoplastic lesions of the gastrointestinal tract. We performed an electronic search of the MEDLINE and the Cochrane Controlled Trials Register databases for relevant studies published up to May 2019. Trials exclusively recruiting patients undergoing ESD for superficial gastrointestinal cancer were considered eligible for inclusion. Thirty-three articles including 3,134 patients met the inclusion criteria. The studies evaluated different approaches for widening the endoscopic view, including magnetic anchor-guided ESD (3 studies), use of a second endoscope (5 studies), clip-involving technique (21 studies), and miscellaneous methods (4 studies). Among them, only 6 were randomized controlled trials evaluating different approaches. Overall, the implementation of methods that assist traction during ESD significantly improved the operating time and R0 resection rate and decreased the rate of complications (bleeding and perforation). Interventions that assist traction seem effcacious in improving tissue traction, thus facilitating ESD performance.

Endoscopic Management of Post-Polypectomy Bleeding: Aditya Gutta, Mark A. Gromski; Clin Endosc 2020;53(3):302-310. Published online September 17, 2019; DOI: https://doi.org/10.5946/ce.2019.062

Abstract PDF PubReader ePub

Post-polypectomy bleeding (PPB) is one of the most common complications of endoscopic polypectomy. There are multiple risk factors related to patient and polyp characteristics that should be considered. In most cases, immediate PPB can be effectively managed endoscopically when recognized and managed promptly. Delayed PPB can manifest in a myriad of ways. In severe delayed PPB, resuscitation for hemodynamic stabilization should be prioritized, followed by endoscopic evaluation and therapy once the patient is stabilized. Future areas of research in PPB include the risks of direct oral anticoagulants and of specific electrosurgical settings for hot-snare polypectomy vs. cold-snare polypectomy, benefits of closure of post-polypectomy mucosal defects using through-the-scope clips, and prospective comparative evaluation of newer hemostasis agents such as hemostatic spray powder and over-the-scope clips.

Background
/Aims: Peroral endoscopic myotomy (POEM) is a novel procedure for the treatment of achalasia and spastic esophageal disorders. Experience with POEM is limited, but its reported outcomes are excellent. It is deemed safe even for patients with prior interventions.
Methods
This retrospective review included patients who underwent POEM at a tertiary US center. POEM was performed in a multidisciplinary approach by advanced endoscopists and foregut surgeons. Clinical success was defined as a post-POEM Eckardt score ≤3.
Results
A total of 125 patients were included. Median follow-up period was 18 months (interquartile range, 10–22 months). Clinical success was achieved in 92% of patients and persisted at 12 months in 88% of patients. Mucosal barrier failure (MBF) occurred in 7 patients, 2 of whom required surgical intervention. MBF was more common in patients with prior laparoscopic Heller myotomy (19% vs. 3%, p=0.015). MBF requiring surgical intervention occurred early in the learning curve.
Conclusions
POEM is safe and effective in the treatment of achalasia and spastic esophageal disorders even after failed prior interventions.

Endoscopic Factors that Can Predict Histological Ulcerations in Early Gastric Cancers: Jaesin Lee, Byung-Wook Kim, Cheal Wung Huh, Joon Sung Kim, Lee-So Maeng; Clin Endosc 2020;53(3):328-333. Published online January 7, 2020; DOI: https://doi.org/10.5946/ce.2019.133

Abstract PDF PubReader ePub

Background
/Aims: Predicting histological ulceration in early gastric cancer (EGC) during endoscopic examination is crucial for endoscopists deciding on the treatment modality. The aim of this study was to investigate the endoscopic factors that can predict histological ulcerations in EGCs.
Methods
We retrospectively analyzed patients who underwent endoscopic submucosal dissection (ESD) for EGC. Clinical features and endoscopic characteristics of EGC such as location, histological differentiation, longest diameter, tumor morphology, mucosal break, converging fold, color change, and surface irregularity were reviewed. Histological ulceration was defined based on ESD specimens.
Results
A total of 633 EGC lesions from 613 patients were included and histological ulcerations were found in 90 lesions (14.2%). Presence of converging folds, tumor morphology, and color changes on endoscopic examination were related to histological ulceration in the univariate analysis and converging folds along with color changes were statistically significant factors in the multivariate analysis. Kaplan–Meier analysis showed that patients with histological ulcerations in EGCs tended to have higher marginal recurrence rates.
Conclusions
Mucosal breaks are not equivalent to histological ulcerations. Rather, the existence of converging folds and color changes during endoscopic examination suggest histological ulcerations. Endoscopists should consider these factors when they decide the treatment modality for EGCs.

Three-Dimensional Flexible Endoscopy Can Facilitate Efficient and Reliable Endoscopic Hand Suturing: An ex-vivo Study: Jun Omori, Osamu Goto, Kazutoshi Higuchi, Takamitsu Umeda, Naohiko Akimoto, Masahiro Suzuki, Kumiko Kirita, Eriko Koizumi, Hiroto Noda, Teppei Akimoto, Mitsuru Kaise, Katsuhiko Iwakiri; Clin Endosc 2020;53(3):334-338. Published online April 24, 2020; DOI: https://doi.org/10.5946/ce.2019.207

Abstract PDF Supplementary Material PubReader ePub

Background
/Aims: Three-dimensional (3D) flexible endoscopy, a new imaging modality that provides a stereoscopic view, can facilitate endoscopic hand suturing (EHS), a novel intraluminal suturing technique. This ex-vivo pilot study evaluated the usefulness of 3D endoscopy in EHS.
Methods
Four endoscopists (two certified, two non-certified) performed EHS in six sessions on a soft resin pad. Each session involved five stitches, under alternating 3D and two-dimensional (2D) conditions. Suturing time (sec/session), changes in suturing time, and accuracy of suturing were compared between 2D and 3D conditions.
Results
The mean suturing time was shorter in 3D than in 2D (9.8±3.4 min/session vs. 11.2±5.1 min/session) conditions and EHS was completed faster in 3D conditions, particularly by non-certified endoscopists. The suturing speed increased as the 3D sessions progressed. Error rates (failure to grasp the needle, failure to thread the needle, and puncture retrial) in the 3D condition were lower than those in the 2D condition, whereas there was no apparent difference in deviation distance.
Conclusions
3D endoscopy may contribute to increasing the speed and accuracy of EHS in a short time period. Stereoscopic viewing during 3D endoscopy may help in efficient skill acquisition for EHS, particularly among novice endoscopists.

Endocuff-Assisted versus Cap-Assisted Colonoscopy Performed by Trainees: A Retrospective Study: Yutaka Okagawa, Tetsuya Sumiyoshi, Yusuke Tomita, Shutaro Oiwa, Fumihiro Ogata, Takashi Jin, Masahiro Yoshida, Ryoji Fujii, Takeyoshi Minagawa, Kohtaro Morita, Hideyuki Ihara, Michiaki Hirayama, Hitoshi Kondo; Clin Endosc 2020;53(3):339-345. Published online January 10, 2020; DOI: https://doi.org/10.5946/ce.2019.124

Abstract PDF PubReader ePub

Background
/Aims: The adenoma detection rate (ADR) of screening colonoscopies performed by trainees is often lower than that of colonoscopies performed by experts. The effcacy of cap-assisted colonoscopy (CAC) in adenoma detection is well documented, especially that of CACs performed by trainees. Endocuff, a new endoscopic cap, is reportedly useful for adenoma detection; however, no trials have compared the effcacy of Endocuff-assisted colonoscopy (EAC) and CAC conducted by trainees. Therefore, the present study retrospectively compared the effcacy between EAC and CAC in trainees.
Methods
This was a single-center, retrospective study involving 305 patients who underwent either EAC or CAC performed by three trainees between January and December 2018. We evaluated the ADR, mean number of adenomas detected per patient (MAP), cecal intubation rate, cecal intubation time, and occurrence of complications between the EAC and CAC groups.
Results
The ADR was significantly higher in the EAC group than in the CAC group (54.3% vs. 37.3%, p=0.019), as was the MAP (1.36 vs. 0.74, p=0.003). No significant differences were found between the groups with respect to the cecal intubation rate or cecal intubation time. No major complications occurred in either group.
Conclusions
Our results suggest that EAC exhibits increased ADR and MAP compared to CAC when performed by trainees.

Validation of a Novel Endoscopic Retrograde Cholangiopancreatography Cannulation Simulator: Pichamol Jirapinyo, Andrew C. Thompson, Hiroyuki Aihara, Marvin Ryou, Christopher C. Thompson; Clin Endosc 2020;53(3):346-354. Published online February 17, 2020; DOI: https://doi.org/10.5946/ce.2019.105

Abstract PDF Supplementary Material PubReader ePub

Background
/Aims: Endoscopic retrograde cholangiopancreatography (ERCP) requires a unique skill set. Currently, there is no objective methodology to assess and train a professional to perform ERCP. This study aimed to develop and validate a novel ERCP simulator.
Methods
The simulator consists of papillae presenting different anatomy and positioned in varied locations. Deep cannulation of the pancreatic duct, followed by the bile duct, was performed. The time allotted was 5 minutes. The content validity indexes (CVIs) for realism, relevance, and representativeness were calculated. Correlation between ERCP experience and simulator score was determined.
Results
Twenty-three participants completed the simulation. The CVIs for realism were orientation of duodenoscope to papilla (1.00), angulation of papillotome to achieve cannulation (0.71), and haptic feedback during cannulation (0.80). The CVIs for relevance were use of elevator (1.00), wheels to achieve en face orientation (1.00), and papillotome for selective cannulation (1.00). Regarding CVI for representativeness, the results were as follows: basic cannulation (0.83), papilla locations (0.83), and papilla anatomies (0.80). The novice, intermediate, and experienced groups scored 6.7±8.7, 30.0±16.3, and 74.4±43.9, respectively (p<0.0001). There was a strong correlation between the ERCP experience level and the individual’s simulator score (Pearson value of 0.77, R2 of 0.60).
Conclusions
This simulator appears to be realistic, relevant, and representative of ERCP cannulation techniques. Additionally, it is effective at objectively assessing basic ERCP skills by differentiating scores based on clinical experience.

Abstract PDF PubReader ePub

Background
/Aims: Endoscopic ultrasonography (EUS)-guided drainage is the preferred approach for infected or symptomatic pancreatic fluid collections (PFCs). Here, we developed an algorithm for the management of pancreatitis complicated by PFCs and report on its effcacy and safety.
Methods
Between September 2011 and October 2017, patients were prospectively managed according to the algorithm. PFCs were classified as poorly organized fluid collections (POFCs), pancreatic pseudocysts (PPs), or walled-off pancreatic necrosis (WOPN). Clinical success was defined as a decrease in PFC size by ≥50% of the maximal diameter or to ≤2 cm.
Results
A total of 108 patients (62% male; mean age, 53 years) were included: 13 had POFCs, 43 had PPs, and 52 had WOPN. Seventytwo patients (66%) required a pancreatic duct (PD) stent, whereas 65 (60%) received enteral feeding. A total of 103 (95%) patients achieved clinical success. Eight patients experienced complications including bleeding (n=6) and surgical intervention (n=2). Patients with enteral feeding were 3.4 times more likely to achieve resolution within 60 days (p=0.0421), whereas those with PD stenting was five times more likely to achieve resolution within 90 days (p=0.0069).
Conclusions
A high PFC resolution rate can be achieved when a dedicated algorithm encompassing EUS-guided drainage, PD stenting, and early enteral feeding is adopted.

Abstract PDF Supplementary Material PubReader ePub

Tracheoesophageal fistulas (TEFs) have traditionally been managed surgically, but the endoscopic approach is widely performed as a less invasive alternative. Different closure techniques have been proposed with inconsistent results. An over-the-scope clip (OTSC) appears to be a reasonable option, but long-term results have not been well defined. We report the long-term outcomes of a complex case of successful closure of a benign refractory TEF using an OTSC after failed surgical management and esophageal stent placement.

Although gastroesophageal damage is commonly induced by accidental drinking of a strong acid or alkali, damage due to the consumption of a vinegar beverage is not well known. We report a case of corrosive esophageal ulcer found in an adolescent consuming a vinegar drink daily. A 15-year-old male visited the emergency room presenting with hematemesis and severe epigastric pain. Multiple longitudinal ulcers, concurrent mucosal hemorrhage, and denuded mucosa were noted in the whole of the esophagus via an endoscopic examination. He had been drinking a vinegar beverage daily without sufficient dilution. The patient was treated with corticosteroid, antibiotic therapy, and mucosa protecting alginate medication and was asked to fast for a week. The follow-up endoscopy showed improvement of the esophageal injuries. Overall, continuous consumption of a vinegar beverage can result in acidic burns and destruction of the surface of the upper gastrointestinal tract. Therefore, vinegar beverages should be considered as corrosive agents.

Saadulaeva, Nadezda V. Konkina; Clin Endosc 2020;53(3):370-373. Published online August 20, 2019; DOI: https://doi.org/10.5946/ce.2019.109

Abstract PDF PubReader ePub

Submucosal tunneling endoscopic technique can be useful in obtaining esophageal muscle specimens in patients with esophageal motility disorders. Here, we describe the case of a patient with systemic sclerosis. Histological verification of the esophageal involvement in the pathological process was required for the treatment. There were no intra- and post- operational complications.
