Evaluation of a new method, "non-injection resection using bipolar soft coagulation mode (NIRBS)", for colonic adenomatous lesions

A method of "Noninjecting Resection using Bipolar Soft coagulation mode; NIRBS" for superficial non-ampullary duodenal epithelial tumor: a pilot study

BACKGROUND

Complete endoscopic resection of superficial non-ampullary duodenal epithelial tumors (SNADETs) is technically difficult, especially with an extremely high risk of adverse event (AE), although various endoscopic resection methods including endoscopic mucosal resection (EMR), underwater EMR (UEMR), and endoscopic submucosal dissection (ESD) have been tried for SNADETs. Accordingly, a novel simple resection method that can completely resect tumors with a low risk of AEs should be developed.

AIMS

A resection method of Noninjecting Resection using Bipolar Soft coagulation mode (NIRBS) which has been reported to be effective and safe for colorectal lesions is adapted for SNADETs. In this study we evaluated its effectiveness, safety, and simplicity for SNADETs measuring ≤ 20 mm.

RESULTS

This study included 13 patients with resected lesions with a mean size of 7.8 (range: 3-15) mm. The pathological distributions of the lesions were as follows: adenomas, 77% (n = 10) and benign and non-adenomatous lesions, 23% (n = 3). The en bloc and R0 resection rate was 100% (n = 13). The median procedure duration was 68 s (32-105). None of the patients presented with major AEs including bleeding and perforation.

CONCLUSIONS

Large studies such as prospective, randomized, and controlled trials should be conducted for the purpose of validating effectiveness, safety, and simplicity of the NIRBS for SNADETs measuring ≤ 20 mm suggested in this study.

International Digestive Endoscopy Network Consensus on the Management of Antithrombotic Agents in Patients Undergoing Gastrointestinal Endoscopy

Antithrombotic agents, including antiplatelet agents and anticoagulants, are widely used in Korea because of the increasing incidence of cardiocerebrovascular disease and the aging population. The management of patients using antithrombotic agents during endoscopic procedures is an important clinical challenge. The clinical practice guidelines for this issue, developed by the Korean Society of Gastrointestinal Endoscopy, were published in 2020. However, new evidence on the use of dual antiplatelet therapy and direct anticoagulant management has emerged, and revised guidelines have been issued in the United States and Europe. Accordingly, the previous guidelines were revised. Cardiologists were part of the group that developed the guideline, and the recommendations went through a consensus-reaching process among international experts. This guideline presents 14 recommendations made based on the Grading of Recommendations, Assessment, Development, and Evaluation methodology and was reviewed by multidisciplinary experts. These guidelines provide useful information that can assist endoscopists in the management of patients receiving antithrombotic agents who require diagnostic and elective therapeutic endoscopy. It will be revised as necessary to cover changes in technology, evidence, or other aspects of clinical practice.
