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.

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.

Strongyloidiasis Presenting as Yellowish Nodules in Colonoscopy of an Immunocompetent Patient: Hannah Ra, Jun-Won Chung, Dong Hae Chung, Jung Ho Kim, Yoon Jae Kim, Kyoung Oh Kim, Kwang An Kwon, Dong Kyun Park; Clin Endosc 2019;52(1):80-82. Published online August 30, 2018; DOI: https://doi.org/10.5946/ce.2018.078

Abstract PDF PubReader ePub

Strongyloides stercoralis is endemic to tropical and subtropical regions, and infections are usually asymptomatic. However, immunocompromised patients, such as those receiving immunosuppressive therapy, high-dose steroids, or chemotherapy, can develop fatal hyperinfections. An 84-year-old man without any symptoms was diagnosed with strongyloidiasis during a regular screening colonoscopy. His medical history only involved a gastric endoscopic submucosal dissection for early gastric cancer 6 months previously. Few cases have been published about asymptomatic strongyloidiasis diagnosed in an immunocompetent host via endoscopic mucosal resection with characteristic colonoscopic findings. We report a case of colon-involved asymptomatic strongyloidiasis with specific colonic findings of yellowish-white nodules. This finding may be an important marker of S. stercoralis infection, which could prevent hyperinfections.

Experimental Gastric Non-Balloon Devices: Youn I Choi, Kyoung Oh Kim; Clin Endosc 2018;51(5):420-424. Published online September 27, 2018; DOI: https://doi.org/10.5946/ce.2018.150

Abstract PDF PubReader ePub

Endoscopic bariatric therapies (EBTs) are promising alternatives to the conventional surgeries used to treat obesity and related metabolic conditions, targeting gastrointestinal anatomical and physiological processes. Many EBTs are at various stages of development and are aimed at promoting an early sense of satiety via anatomical and physiological mechanisms. In the present study, we focused on relevant clinical issues and future perspectives with regard to gastric non-balloon methods treating obesity.

Education and Training Guidelines for the Board of the Korean Society of Gastrointestinal Endoscopy: Hee Seok Moon, Eun Kwang Choi, Ji Hyun Seo, Jeong Seop Moon, Ho June Song, Kyoung Oh Kim, Jong Jin Hyun, Sung Kwan Shin, Beom Jae Lee, Sang Heon Lee; Clin Endosc 2017;50(4):345-356. Published online July 31, 2017; DOI: https://doi.org/10.5946/ce.2017.106

Abstract PDF PubReader ePub

The Korean Society of Gastrointestinal Endoscopy (KSGE) developed a gastrointestinal (GI) endoscopy board in 1995 and related regulations. Although the KSGE has acquired many specialists since then, the education and training aims and guidelines were insufficient. During GI fellowship training, obtaining sufficient exposure to some types of endoscopic procedures is difficult. Fellows should acquire endoscopic skills through supervised endoscopic procedures during GI fellowship training. Thus, the KSGE requires training guidelines for fellowships that allow fellows to perform independent endoscopic procedures without supervision. This document is intended to provide principles that the Committee of Education and Training of the KSGE can use to develop practical guidelines for granting privileges to perform accurate GI endoscopy safely. The KSGE will improve the quality of GI endoscopy by providing guidelines for fellowships and supervisors.

Is Image-Enhanced Endoscopy Useful for the Diagnosis and Treatment of Gastrointestinal Tumor?: Kyoung Oh Kim, Yang Suh Ku; Clin Endosc 2013;46(3):248-250. Published online May 31, 2013; DOI: https://doi.org/10.5946/ce.2013.46.3.248

Abstract PDF PubReader ePub

Since the introduction of endoscopic submucosal dissection method for the treatment of early gastric cancer, endoscopic treatment of early gastric cancer has increased exponentially. Accordingly, early diagnosis of cancerous or precancerous lesion has become one of the most important missions for endoscopists. The desire to improve diagnostic capability of white light endoscopy led to the development of new imaging techniques called "image enhanced endoscopy." The usefulness of these image enhanced endoscopy has not been proven yet, although there are several studies reporting diagnostic superiority of these new imaging methods over white light endoscopy. Among these new imaging modalities, narrow band image (NBI) with magnification endoscopy has been most widely used and studied. This manuscript will be focused on the NBI with magnification endoscopy.
