Novel Ablation Therapy Using Endoscopic Irreversible Electroporation in the Bile Duct: A Pilot Animal Study: Kang Won Lee, Jae Min Lee, Hyuk Soon Choi, Eun Sun Kim, Bora Keum, Yeon Seok Seo, Yoon Tae Jeen, Soon Ho Um, Hong Sik Lee, Hoon Jai Chun, Chang Duck Kim, Chi Hyuk Oh, Hong Bae Kim; Clin Endosc 2021;54(3):413-419. Published online October 20, 2020; DOI: https://doi.org/10.5946/ce.2020.126

Background
/Aims: Irreversible electroporation (IRE) is a relatively new ablation method. However, the application of IRE ablation in the treatment of biliary disease has not been attempted. A minimally invasive approach using endoscopic retrograde cholangiopancreatography (ERCP) can be a novel therapeutic modality for IRE ablation. In this study, we aimed to investigate the feasibility of endoscopic IRE for the biliary tract using an animal model.
Methods
A new catheter-type electrode was developed for endoscopic IRE ablation of the biliary tract. We performed ERCP and endoscopic IRE ablations in the normal common bile duct of Yorkshire pigs. The experimental setting of IRE was 500 V/cm (50 pulses, 100-µs length). The animals were sacrificed after 24 hr, and the ablated bile duct was examined.
Results
Well-demarcated focal color changes were observed on the mucosa of the common bile duct. The depth of change after IRE was confined to the mucosal and submucosal layers. Apoptotic changes in the bile duct were observed only around the IRE ablation area. Immunohistochemistry assay showed cell death in the bile duct along the electrode.
Conclusions
Endoscopic IRE ablation using ERCP was successfully performed in the common bile duct. It can be a potential option for the treatment of biliary tumors.

Background
/Aims: Patients may feel embarrassed during colonoscopy. Our study aimed to assess changes in patient preference, over the past decade, for the sex of their colonoscopist.
Methods
Prospective studies were performed at a single health center from July to September 2008, and from July to September 2016. Subjects included colonoscopy patients (2008: 354, 2016: 304) who were asked to complete a questionnaire before colonoscopy.
Results
In 2016, 69 patients (24.9%) expressed a sex preference, compared with 46 patients (14.6%) in 2008. By 2016, female patient preference for a female colonoscopist had significantly increased to 95% (odds ratio [OR], 2.678; 95% confidence interval [CI], 1.418– 5.057; P=0.002). In multivariate analysis, patient sex (OR, 4.404; P=0.000), patient age (OR, 0.977; 95% CI, 0.961–0.992; P=0.004), and year of procedure (OR, 1.674; 95% CI, 1.028–2.752) were statistically significant factors in sex preference. Between 2008 and 2016, female patients preferred a female colonoscopist because of embarrassment. Male patients also preferred a male colonoscopist, and the primary reason shifted from expertise to patient embarrassment (2008: 29%, 2016: 63%).
Conclusions
Patients have an increased gender preference for the colonoscopist because of embarrassment. Taking this into account can increase patient satisfaction during colonoscopy.

Job Stress and Job Satisfaction among Health-Care Workers of Endoscopy Units in Korea: Seung-Joo Nam, Hoon Jai Chun, Jeong Seop Moon, Sung Chul Park, Young-Jae Hwang, In Kyung Yoo, Jae Min Lee, Seung Han Kim, Hyuk Soon Choi, Eun Sun Kim, Bora Keum, Yoon Tae Jeen, Hong Sik Lee, Chang Duck Kim; Clin Endosc 2016;49(3):266-272. Published online February 22, 2016; DOI: https://doi.org/10.5946/ce.2015.085

Abstract PDF Supplementary Material PubReader ePub

Background
/Aims: The management of job-related stress among health-care workers is critical for the improvement of healthcare services; however, there is no existing research on endoscopy unit workers as a team. Korea has a unique health-care system for endoscopy unit workers. In this study, we aimed to estimate job stress and job satisfaction among health-care providers in endoscopy units in Korea.
Methods
We performed a cross-sectional survey of health-care providers in the endoscopy units of three university-affiliated hospitals in Korea. We analyzed the job stress levels by using the Korean occupational stress scale, contributing factors, and job satisfaction.
Results
Fifty-nine workers completed the self-administered questionnaires. The job stress scores for the endoscopy unit workers (46.39±7.81) were relatively lower compared to those of the national sample of Korean workers (51.23±8.83). Job stress differed across job positions, with nurses showing significantly higher levels of stress (48.92±7.97) compared to doctors (42.59±6.37). Job stress and job satisfaction were negatively correlated with each other (R² =0.340, p<0.001).
Conclusions
An endoscopy unit is composed of a heterogeneous group of health-care professionals (i.e., nurses, fellows, and professors), and job stress and job satisfaction significantly differ according to job positions. Job demand, insufficient job control, and job insecurity are the most important stressors in the endoscopy unit.

Acute Duodenal Ischemia and Periampullary Intramural Hematoma after an Uneventful Endoscopic Retrograde Cholangiopancreatography in a Patient with Primary Myelofibrosis: Chang Ho Jung, Jong Jin Hyun, Dae Hoe Gu, Eul Sun Moon, Jae Seon Kim, Hong Sik Lee, Chang Duck Kim; Clin Endosc 2014;47(3):270-274. Published online May 31, 2014; DOI: https://doi.org/10.5946/ce.2014.47.3.270

Abstract PDF PubReader ePub

Acute duodenal ischemia and periampullary intramural hematoma are rare complications after endoscopic retrograde cholangiopancreatography (ERCP). A 77-year-old man with splenomegaly complained of abdominal pain caused by common bile duct (CBD) stone. After successful removal of the CBD stone without immediate complications, the patient developed intramural hematoma around the ampulla of Vater along with diffuse duodenal edema. The findings were compatible with acute intestinal ischemia, and further evaluation revealed that he had underlying primary myelofibrosis. Myeloproliferative diseases are known to be significantly associated with an increased risk of thrombohemorrhagic complications. Therefore, particular attention should be given to this group of patients when a high-risk procedure such as ERCP is performed.

Feasibility of Obtaining Quantitative 3-Dimensional Information Using Conventional Endoscope: A Pilot Study: Jong Jin Hyun, Hoon Jai Chun, Bora Keum, Yeon Seok Seo, Yong Sik Kim, Yoon Tae Jeen, Hong Sik Lee, Soon Ho Um, Chang Duck Kim, Ho Sang Ryu, Jong-Wook Lim, Dong-Gi Woo, Young-Joong Kim, Myo-Taeg Lim; Clin Endosc 2012;45(3):182-188. Published online August 22, 2012; DOI: https://doi.org/10.5946/ce.2012.45.3.182

Abstract PDF PubReader ePub

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 (d₁₂). 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 of H (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.

Assessment on the Potential Role of Applying Cryoprobe for Tissue Ablation: Min Ho Seo, Yoon Tae Jeen, Sang Jung Park, Sun Young Kim, Hye Jin Cho, Hyuk Sun Choi, Hoon Jai Chun, Chang Duck Kim, Ho Sang Ryu, Yang Seok Chae; Clin Endosc 2012;45(1):67-72. Published online March 31, 2012; DOI: https://doi.org/10.5946/ce.2012.45.1.67

Abstract PDF PubReader ePub: Background/Aims
Cryotherapy is the therapeutic application for tissue ablation. Clinical applications of cryotherpy such as in pulmonology have increased. Until now, its development in gastroenterology has been insignificant. But, as clinical application such as mucosal ablation on Barrett's esophagus became possible, various applications have been developed. Therefore, it is important to make standards of tissue injury's extent in cryotherapy prior to clinical trial. We evaluated the tissue injury according to the application of cryoprobe with a pig model.
Methods
Cryoprobe was applied to several different segments of the esophagus and stomach for various lengths of time using various number of probe's contact in a pig model. After 48 hours, esophagus and stomach were harvested and histological tissue injury was assessed. The extent of tissue injury was decided by the injury of the deepest layer.
Results
Endoscopic application of cryoprobe on esophagus and stomach resulted in a dose-dependent injury: esophageal necrosis was limited to the submucosa after 10 seconds of cryotherapy, and extended to involve the transmural necrosis after over 15 seconds. Necrosis on stomach was extended to involve the transmural necrosis after over 20 seconds.
Conclusions
Positive relationship was seen between the duration and frequency of cryoprobe application and the extent of tissue injury.

Rifampin-induced Pseudomembranous Colitis with Rectosigmoid Sparing: Sun Young Yim, Ja Seol Koo, Ye Ji Kim, Sang Jung Park, Jin Nam Kim, Sung Woo Jung, Hyung Joon Yim, Sang Woo Lee, Jai Hyun Choi, Chang Duck Kim; Clin Endosc 2011;44(2):137-139. Published online December 31, 2011; DOI: https://doi.org/10.5946/ce.2011.44.2.137

Abstract PDF PubReader ePub

Pseudomembranous colitis (PMC) is known to be associated with antibiotic treatment, but is not commonly related to antitubercular (anti-TB) agent, rifampin. PMC is frequently localized to rectum and sigmoid colon, which can be diagnosed with sigmoidoscopy. We report a case of rifampin-induced PMC with rectosigmoid sparing in a pulmonary tuberculosis patient. An 81-year-old man using anti-TB agents was admitted with a 30-day history of severe diarrhea and general weakness. On colonoscopy, nonspecific findings such as mucosal edema and erosion were found in sigmoid colon, whereas multiple yellowish plaques were confined to cecal mucosa only. Biopsy specimen of the cecum was compatible with PMC. Metronidazole was started orally, and the anti-TB medications excluding rifampin were readministerred. His symptoms remarkably improved within a few days without recurrence. Awareness of rectosigmoid sparing PMC in patients who develop diarrhea during anti-TB treatment should encourage early total colonoscopy.

Abstract PDF PubReader ePub

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 and Pseudomonas 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.
