Abstract
Introduction This single-center retrospective study compared underwater clip closure (UCC) with conventional clip closure (CCC) under routine gas insufflation for post-endoscopic submucosal dissection (ESD) ulcers of colorectal lesions measuring ≤5 cm. Methods Between May 2021 and June 2023, 89 patients were enrolled. Since March 2022, all cases underwent UCC. Patients were divided into the UCC group (n = 52) and the CCC group (n = 37). Primary outcomes were complete closure rate and incidence of post-ESD coagulation syndrome (PECS), delayed bleeding, and perforation. Secondary outcomes included closure time and number of clips used. Results Complete closure was achieved in all cases, with no PECS, delayed bleeding, or perforation in either group. Median closure time was significantly shorter in the UCC group (10 min [IQR, 7-14]) than in the CCC group (11 min [IQR, 8.5-19]; p = 0.044). The number of clips used was similar (median 10 in both groups; p = 0.290). Multiple regression analysis identified both resection area (p < 0.001) and closure method (p = 0.002) as independent factors affecting closure time. Conclusion UCC may decrease the time required for post-ESD closure of colorectal lesions measuring ≤5 cm, while using a comparable number of clips to CCC, with no serious complications.
期刊介绍:
''Digestion'' concentrates on clinical research reports: in addition to editorials and reviews, the journal features sections on Stomach/Esophagus, Bowel, Neuro-Gastroenterology, Liver/Bile, Pancreas, Metabolism/Nutrition and Gastrointestinal Oncology. Papers cover physiology in humans, metabolic studies and clinical work on the etiology, diagnosis, and therapy of human diseases. It is thus especially cut out for gastroenterologists employed in hospitals and outpatient units. Moreover, the journal''s coverage of studies on the metabolism and effects of therapeutic drugs carries considerable value for clinicians and investigators beyond the immediate field of gastroenterology.
