Endoscopic submucosal dissection and tunneling procedures using a novel all-in-one bipolar device

Abstract

Background and study aims Recent innovations in devices and techniques have revolutionized the field of endoscopic resection procedures. In this study, we evaluated the safety and feasibility of endoscopic submucosal dissection and tunneling procedures with a novel, multipurpose bipolar device.

Patients and methods Data from consecutive patients who underwent per-oral endoscopic myotomy (POEM), submucosal tunneling endoscopic resection (STER), and endoscopic submucosal dissection (ESD) using a novel bipolar device (December 2019 to February 2020) were analyzed retrospectively. Procedure duration, technical success, and adverse events (AEs) were recorded.

Results A total of 10 procedures were performed using the novel bipolar device during the study period. The procedures included POEM (n = 7), STER for esophageal sub-epithelial tumor (n = 1), ESD for rectal polyp (n = 1), and gastric neuroendocrine tumor (n = 1). POEM was successfully completed in all patients. In patients who underwent STER and ESD, en-bloc resection was achieved in all. Mean procedure time for submucosal tunneling procedures (POEM and STER) was 59.12 ± 31.12 minutes. The procedures were completed without the requirement for exchange of accessories in eight cases (80 %). There were no major AEs. Mild and moderate AEs occurred during POEM and included capno-peritoneum (n = 1), retroperitoneal CO₂ (n = 1), and empyema (n = 1).

Conclusion ESD and tunneling procedures can be safely performed without the need for exchange of accessories using a novel bipolar device. Randomized comparison with conventional knives isrequired to confirm the utility of this device.
