Background
/Aims: Intragastric balloon (IGB) is the only available endoscopic bariatric and metabolic therapy in Korea. End-ball (Endalis) has the longest history of clinical use among the IGBs available in Korea. However, little clinical data on this system have been reported. In this study, we aimed to evaluate the efficacy and safety of End-ball in Korea.
Methods
We performed a retrospective cohort study of patients who underwent IGB insertion (End-ball) from 2013 to 2019. Demographic and anthropometric data were collected. The efficacy and safety of IGB treatment were analyzed.
Results
In total, 80 patients were included. Mean age was 33.7 years and 83.8% were female. Initial body mass index was 34.48±4.69 kg/m2. Body mass index reduction was 3.72±2.63 kg/m2 at the time of IGB removal. Percent of total body weight loss (%TBWL) was 10.76%±6.76%. Percentage excess body weight loss was 43.67%±27.59%. Most adverse events were minor, and 71.4% of participants showed nausea, vomiting, or abdominal pain.
Conclusions
IGB treatment showed good efficacy and safety profile in Korean patients with obesity. In terms of %TBWL and percentage excess body weight loss, the efficacy was similar to that in the Western population.

Background
/Aims: This study aimed to determine the current status of facilities, equipment, and personnel for endoscopic sedation from endoscopy units of representative hospitals in South Korea.
Methods
A questionnaire survey was conducted on 50 qualified endoscopy units accredited by the Korean Society of Gastrointestinal Endoscopy.
Results
All included endoscopy units had regulations and educational programs regarding sedation training for endoscopists and nursing personnel. There present one assisting nurse during endoscopy in 35 units (70%) and at least two nurses in 12 units (24.0%). All endoscopy units had examination rooms equipped with oxygen supply and suction systems. Endoscopist-directed sedation was performed in 48 units (96.0%). Propofol-based sedation was the most used sedation method. All units had a separate recovery bay. The daily number of patients per bed was greater than 10 in 17 units (34.0%). In 26 (52.0%) units, a single nurse cared for ≥10 patients per day. All the units fulfilled the discharge criteria.
Conclusions
This study presents data regarding endoscopic sedation clinical practice in 50 endoscopy units in South Korea. This study presents the current status of endoscopic sedation clinical practice in 50 qualified endoscopy units accredited by the KSGE, which provide excellent quality management.

Dedicated Cold Snare vs. Traditional Snare for Polypectomy of Diminutive and Small Lesions in a Porcine Model: A Research Group for Endoscopic Instruments and Stents (REIS) Study: Han Hee Lee, Bo-In Lee, Jung-Wook Kim, Hyun Lim, Si Hyung Lee, Jun-Hyung Cho, Yunho Jung, Kyoung Oh Kim, Chan Gyoo Kim, Kee Myung Lee, Jong-Jae Park, Myung-Gyu Choi, Hoon Jai Chun, Ho Gak Kim; Clin Endosc 2021;54(3):390-396.

Background
/Aims: The aim of this in vivo animal study was to evaluate the effectiveness and safety of dedicated cold snare (DCS) compared with those of traditional snare (TS) for cold snare polypectomy (CSP).
Methods
A total of 36 diminutive (5 mm) and 36 small (9 mm) pseudolesions were made by electrocoagulation in the colons of mini-pigs.
Results
For the diminutive lesions, there were no significant differences in technical success rate, procedure time, or complete resection rate between the DCS and TS groups; the rate of uneven resection margin in the DCS group was significantly lower than that of the TS group. For small lesions, technical success rate and complete resection rate were significantly higher in the DCS group than in the TS group (100% [18/18] vs. 55.6% [10/18], p=0.003; 94.4% [17/18] vs. 40% [4/10], p=0.006). In addition, the procedure duration was significantly shorter, and the rate of uneven resection margin was significantly lower in the DCS group (28.5 sec vs. 66.0 sec, p=0.006; 11.1% [2/18] vs. 100% [10/10], p<0.001). Two cases of perforation occurred in the DCS group. Multivariate analysis revealed that DCS use was independently associated with complete resection.
Conclusions
DCS is superior to TS in terms of technical success, complete resection, and reducing the duration of the procedure for CSP of small polyps.

Accredited Endoscopy Unit Program of Korea: Overview and Qualification: Jung-Wook Kim, Yu Kyung Cho, Jin-Oh Kim, Jae-Young Jang, the Quality Management Committee of Korean Society of Gastrointestinal Endoscopy; Clin Endosc 2019;52(5):426-430. Published online September 30, 2019; DOI: https://doi.org/10.5946/ce.2019.166

Abstract PDF PubReader ePub

The Korean Society of Gastrointestinal Endoscopy introduced the Accredited Endoscopy Unit Program to enhance endoscopy unit quality through systematic quality management in 2012. It was gradually expanded from training hospitals to institutions with 100+ beds, and the criteria for certification were applied according to the actual conditions of each institution. On the basis of the continuous communication with the institutions and feedback, the Accredited Endoscopy Unit Program certification criteria were revised in 2019 and introduced as follows: (1) the qualification criteria for endoscopy doctors and nurses; (2) facilities and equipment; (3) endoscopic examination process; (4) performance; (5) disinfection and infection control; and (6) endoscopic sedation. The assessment items consist of essential and recommended items. All essential items must be met for accreditation to be awarded. The assessment criteria for each evaluation area were revised as follows: (1) upgrading assessment criteria; (2) qualification of endoscopists and reinforcement of quality control education; (3) detailed standards for safety, disinfection, endoscopic sedation, and management instructions; and (4) presentation of new performance measurement of endoscopy and colonoscopy.

Usefulness of Narrow-Band Imaging in Endoscopic Submucosal Dissection of the Stomach: Jung-Wook Kim; Clin Endosc 2018;51(6):527-533. Published online November 19, 2018; DOI: https://doi.org/10.5946/ce.2018.186

Abstract PDF PubReader ePub

There have been many advances in endoscopic imaging technologies. Magnifying endoscopy with narrow-band imaging is an innovative optical technology that enables the precise discrimination of structural changes on the mucosal surface. Several studies have demonstrated its usefulness and superiority for tumor detection and differential diagnosis in the stomach as compared with conventional endoscopy. Furthermore, magnifying endoscopy with narrow-band imaging has the potential to predict the invasion depth and tumor margins during gastric endoscopic submucosal dissection. Classifications of the findings of magnifying endoscopy with narrow-band imaging based on microvascular and pit patterns have been proposed and have shown excellent correlations with invasion depth confirmed by microscopy. In terms of tumor margin prediction, magnifying endoscopy with narrow-band imaging offers superior delineation of gastric tumor margins compared with traditional chromoendoscopy with indigo carmine. The limitations of narrow-band imaging, such as the need for considerable training, long procedure time, and lack of studies about its usefulness in undifferentiated cancer, should be resolved to confirm its value as a complementary method to endoscopic submucosal dissection. However, the role of magnifying endoscopy with narrow-band imaging is expected to increase steadily with the increasing use of endoscopic submucosal dissection for the treatment of gastric tumors.

Congenital Jejunal Diverticular Bleeding in a Young Adult: Ji-Yung Lee, Jae-Young Jang, Min-Je Kim, Tae-In Lee, Jung-Wook Kim, Young-Woon Chang; Clin Endosc 2017;50(5):495-499. Published online June 14, 2017; DOI: https://doi.org/10.5946/ce.2016.154

Abstract PDF Supplementary Material PubReader ePub

Diverticular bleeding of the small bowel is rare and occurs primarily in adults aged more than 60 years. In younger adults, Meckel’s diverticulum, a true diverticulum that congenitally occurs in the distal ileum, is the most common cause of diverticular bleeding of the small bowel. Unlike Meckel’s diverticula, other kinds of small bowel diverticula are not congenital and their incidence is related to age. Furthermore, congenital true diverticular bleeding of the jejunum in adults is very rare. We report the case of a 24-year-old man with subepithelial tumor-like lesion accompanied with obscure overt gastrointestinal bleeding (OOGIB). This lesion was initially suspected to be a subepithelial tumor based on radiologic tests and capsule endoscopy. He was finally diagnosed with a congenital true diverticulum in the jejunum with the appearance of a Meckel’s diverticulum after surgical resection.
