Endoscopic stenting for malignant gastric outlet obstruction: focusing on comparison of endoscopic stenting and surgical gastrojejunostomy
Sun Gyo Lim, Chan Gyoo Kim
Clin Endosc 2024;57(5):571-580.   Published online February 23, 2024
DOI: https://doi.org/10.5946/ce.2023.160
AbstractAbstract PDFPubReaderePub
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.

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.   Published online September 10, 2020
DOI: https://doi.org/10.5946/ce.2020.096
AbstractAbstract PDFSupplementary MaterialPubReaderePub
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.

Bleeding after Endoscopic Resection in Patients with End-Stage Renal Disease on Dialysis: A Multicenter Propensity Score-Matched Analysis
In Kyung Yoo, Chan Gyoo Kim, Young Ju Suh, Younkyung Oh, Gwang Ho Baik, Sun Moon Kim, Young Dae Kim, Chul-Hyun Lim, Jung Won Jeon, Su Jin Hong, Byoung Wook Bang, Joon Sung Kim, Jun-Won Chung
Clin Endosc 2020;53(4):452-457.   Published online October 25, 2019
DOI: https://doi.org/10.5946/ce.2019.107
AbstractAbstract PDFPubReaderePub
Background
/Aims: Frequent bleeding after endoscopic resection (ER) has been reported in patients with end-stage renal disease (ESRD). We aimed to evaluate the association and clinical significance of bleeding with ER in ESRD patients on dialysis.
Methods
Between February 2008 and December 2018, 7,571 patients, including 47 ESRD patients on dialysis who underwent ER for gastric neoplasia, were enrolled. A total of 47 ESRDpatients on dialysis were propensity score-matched 1:10 to 470 non-ESRD patients, to adjust for between-group differences in variables such as age, sex, comorbidities, anticoagulation use, tumor characteristics, and ER method. Matching was performed using an optimal matching algorithm. For the matched data, clustered comparisons were performed using the generalized estimating equation method. Medical records were retrospectively reviewed. Frequency and outcomes of post-ER bleeding were evaluated.
Results
Bleeding was more frequent in the ESRD with dialysis group than in the non-ESRD group. ESRD with dialysis conferred a significant risk of post-ER bleeding (odds ratio, 6.1; 95% confidence interval, 2.7–13.6; p<0.0001). All post-ER bleeding events were controlled using endoscopic hemostasis except in 1 non-ESRD case that needed surgery.
Conclusions
ESRD with dialysis confers a bleeding risk after ER. However, all bleeding events could be managed endoscopically without sequelae. Concern about bleeding should not stop endoscopists from performing ER in ESRD patients on dialysis.

Efficacy of the Over-the-Scope Clip System for Treatment of Gastrointestinal Fistulas, Leaks, and Perforations: A Korean Multi-Center Study
Hang Lak Lee, Joo Young Cho, Jun-Hyung Cho, Jong Jae Park, Chan Gyoo Kim, Seong Hwan Kim, Joung-Ho Han
Clin Endosc 2018;51(1):61-65.   Published online August 29, 2017
DOI: https://doi.org/10.5946/ce.2017.027
AbstractAbstract PDFPubReaderePub
Background
/Aims: Currently, a new over-the-scope clip (OTSC) system has been introduced. This system has been used for gastrointestinal perforations and fistulas in other countries. The aim of our study is to examine the therapeutic success rate of endoscopic treatment using the OTSC system in Korea.
Methods
This was a multicenter prospective study. A total of seven endoscopists at seven centers performed this procedure.
Results
A total of 19 patients were included, with gastrointestinal leakages from anastomosis sites, fistulas, or esophageal perforations due to Boerhaave’s syndrome. Among these, there were three gastrojejunostomy sites, three esophagojejunostomy sites, four esophagogastrostomy sites, one esophagocolonostomy site, one jejuno-jejunal site, two endoscopic full thickness resection site closures, one Boerhaave’s syndrome, two esophago-bronchial fistulas, one gastrocolonic fistula, and one colonopseudocyst fistula. The size of the leakage ranged from 5 to 30 mm. The median procedure time was 16 min. All cases were technically successful. Complete closure of the leak was achieved in 14 of 19 patients using OTSC alone.
Conclusions
The OTSC system is a safe and effective method for the management of gastrointestinal leakage, especially in cases of anastomotic leakage after surgery.

Endoscopic Full-Thickness Resection Combined with Laparoscopic Surgery
Chan Gyoo Kim
Clin Endosc 2018;51(1):33-36.   Published online January 12, 2018
DOI: https://doi.org/10.5946/ce.2017.153
AbstractAbstract PDFPubReaderePub
Endoscopic full-thickness resection combined with laparoscopic surgery was recently developed. These procedures could be categorized as “Cut first and then suture” and “Suture first and then cut”. “Cut first and then suture” includes laparoscopic and endoscopic cooperative surgery (LECS) and laparoscopy-assisted endoscopic full-thickness resection (LAEFR). Recent studies have demonstrated the safety and efficacy of LECS and LAEFR. However, these techniques are limited by the related exposure of the tumor and gastric mucosa to the peritoneal cavity and manipulation of these organs, which could lead to viable cancer cell seeding and the spillage of gastric juice into the peritoneal cavity. In the “Suture first and then cut” technique, the serosal side of the stomach is sutured to invert the stomach and subsequently endoscopic resection is performed. In this article, details of these techniques, including their advantages and limitations, are described.

Endoscopic Removal of a Migrated Coil after Embolization of a Splenic Pseudoaneurysm: A Case Report
Yoo Min Han, Jong Yeul Lee, Il Ju Choi, Chan Gyoo Kim, Soo-Jeong Cho, Jun Ho Lee, Hyun Beom Kim, Ji Min Choi
Clin Endosc 2014;47(2):183-187.   Published online March 31, 2014

AbstractAbstract PDFPubReaderePub

Splenic artery pseudoaneurysms can be caused by pancreatitis, trauma, or operation. Traditionally, the condition has been managed through surgery; however, nowadays, transcatheter arterial embolization is performed safely and effectively. Nevertheless, several complications of pseudoaneurysm embolization have been reported, including coil migration. Herein, we report a case of migration of the coil into the jejunal lumen after transcatheter arterial embolization of a splenic artery pseudoaneurysm. The migrated coil was successfully removed by performing endoscopic intervention.

Tissue Acquisition in Gastric Epithelial Tumor Prior to Endoscopic Resection
Chan Gyoo Kim
Clin Endosc 2013;46(5):436-440.   Published online September 30, 2013

AbstractAbstract PDFPubReaderePub

Endoscopic forceps biopsy is essential before planning an endoscopic resection of upper gastrointestinal epithelial tumors. However, forceps biopsy is limited by its superficiality and frequency of sampling errors. Histologic discrepancies between endoscopic forceps biopsies and resected specimens are frequent. Factors associated with such histologic discrepancies are tumor size, macroscopic type, surface color, and the type of medical facility. Precise targeting of biopsies is recommended to achieve an accurate diagnosis, curative endoscopic resection, and a satisfactory oncologic outcome. Multiple deep forceps biopsies can induce mucosal ulceration in early gastric cancer. Endoscopic resection for early gastric cancer with ulcerative findings is associated with piecemeal resection, incomplete resection, and a risk for procedure-related complications such as bleeding and perforation. Such active ulcers caused by forceps biopsy and following submucosal fibrosis might also be mistaken as an indication for more aggressive procedures, such as gastrectomy with D2 lymph node dissection. Proton pump inhibitors might be prescribed to facilitate the healing of biopsy-induced ulcers if an active ulcer is predicted after deep biopsy. It is unknown which time interval from biopsy to endoscopic resection is appropriate for a safe procedure and a good oncologic outcome. Further investigations are needed to conclude the appropriate time interval.
