Abstract:
Objective:To analyze the effect of the over-the-scope-clip system (OTSC) system in the treatment of iatrogenic gastrointestinal perforation.Methods:Retrospective selection of clinical data from 21 patients with gastrointestinal perforation during endoscopic examination and treatment from May 2016 to December 2023 in the Department of Gastroenterology, Beijing Friendship Hospital, Capital Medical University. By analyzing the patient's basic information, perforation cause, perforation diameter, length of hospital stay, post-treatment outcome, complications, and treatment success rate, the effectiveness of using the OTSC system to treat iatrogenic gastrointestinal perforation is comprehensively evaluated, and the influencing factors that may be related to the failure of OTSC system closure are analyzed. Independent sample t-test is used for inter group comparison of metric data that conforms to normal distribution. Fisher's exact probability test was used for inter group comparison of count data.Results:There were 21 cases of acute iatrogenic gastrointestinal perforation, including 12 males and 9 females, aged (61.95±15.47) years, 4 cases of duodenal perforation, 10 cases of gastric perforation, and 7 cases of colon perforation. The diameter of the perforation was (1.18±0.56)cm, and the perforation sealing time was (8.29±4.42) min. Among the 21 patients, 5 cases of occlusion failed, of which 2 cases of sigmoid colon perforation were transferred to surgery in time due to OTSC insufficiency, 3 cases were perforated in duodenal colon and colonic splenic area, 3 cases of delayed abdominal infection after OTSC system occlusion, 16 cases of OTSC system closure and perforation without complications such as delayed perforation, and the average length of hospital stay of patients in the OTSC system wound closure group was (11.56±6.53) d, which was shorter than that in the OTSC system closure failure group ((38.00±21.34) d), The proportion of passive perforation in the failure group (100%, 5/5) > the success group (31%, 5/16).The occlusion success rate of passive perforation in the OTSC system (50%, 5/10) < active perforation (100%, 11/11), the diameter of perforation of the failure group ((1.72±0.80)cm) was significantly > that of the successful group ((1.06±0.49)cm), the diameter of perforation ≥2.0 cm in the failure group (80.0%, 4/5) was significantly > that of the successful group (12.5%, 2/16), the proportion of duodeno-colonic perforation in the failure group (100.0%, 5/5) > the success group (37.5%, 6/16), the difference was statistically significant ( P values were 0.049, 0.012, 0.012, 0.037, 0.011, and 0.035, respectively). Conclusion:The closure of acute iatrogenic gastrointestinal perforation by the OTSC system has significant therapeutic effects and can reduce the probability of surgical conversion due to perforation to a certain extent. It is worth promoting and applying. The diameter of the perforation (≥2 cm), the perforation method (passive perforation), and the perforation site (the difficult part of duodenum-colon operation) may be the relevant influencing factors for the failure of the occlusion of the OTSC system.
