Abstract

Conventional clip closure of mucosal defects after duodenal endoscopic submucosal dissection decreases the incidence of delayed adverse events, but may result in incomplete closure, depending on size or location. This study aimed to assess the effectiveness of the underwater clip closure method for complete duodenal defect closure without the difficulties associated with conventional closure methods. We investigated 19 patients with 20 lesions who underwent endoscopic submucosal dissection of the duodenum and subsequent mucosal defect closure in underwater conditions at our facility between February 2021 and January 2022. The success rate of the underwater clip closure method was defined as the complete endoscopic closure of the mucosal defect; a success rate of 100% was achieved. The median resected specimen size was 34.3 mm, the median procedure time for mucosal defect closure was 14 min, and the median number of clips used per patient was 12. No delayed adverse events were observed. The underwater clip closure method is a feasible option for complete closure of mucosal defects, regardless of the size or location of a duodenal endoscopic submucosal dissection.

Abstract

Argon plasma coagulation (APC) has been proven to be safein vitro, and has been widely introduced to therapeutic endoscopy. We evaluated the thermal effects on esophageal or gastric wallin vivo, and its effectiveness as an adjunct to incomplete resection of early esophageal and gastric cancer after endoscopic mucosal resection (EMR).Thermal injuries were made using endoscopic APC irradiation in porcine esophagus and stomach under various conditions during general anesthesia, and depth of tissue damage was determined histopathologically. Patients with early gastric cancer (n = 24) and early esophageal cancer (n = 5) were treated with additional APC following microscopically incomplete EMR. APC was applied to coagulate the entire edge of EMR-induced ulcer 1 week after resection at power/gas settings of 50 W and 1.5 L/min in the stomach, and 40 W and 1.5 L/min in the esophagus for less than 5 s at each point.Depth of tissue damage was related to pulse duration and power output. At power/gas settings of 60 W and 2.0 L/min, thermal damage extended across the submucosal layer with 5-s pulse duration in the stomach. Thermal damage with 5-s pulse duration at power/gas settings of 40 W and 2.0 L/min extended to the muscularis propria in the esophagus. In the clinical study of additional APC therapy, the recurrence rate was 6.9% (two of 29 cases).To avoid perforation, we recommend an APC power setting of 40–60 W for less than 5 s in the stomach and a lower power setting with shorter duration in the esophagus. APC seems to reduce recurrence of esophageal or gastric cancer after incomplete EMR. [ABSTRACT FROM AUTHOR]
