Abstract:Objective To explore the efficacy and safety of single forcep endoscopic purse-string suture closing the wound of colorectal after ESD for patients with colorectal lesions.Methods A retrospective study was conducted on the clinical data of 220 patients with 224 colorectal disease and ESD surgery from October 2019 to October 2020. According to whether purse-string suture was performed after ESD, all the patients were divided into study group (the wound was clipped by purse-string suture, n = 121) and the control group (the wound was not closed, n = 103), the completion of treatment, complications and follow-up results were summarized.Results The lesions were located in the rectum (114, 50.89%), left colon (56, 25.00%), right colon (36, 16.07%), and the ileocecal injunction (18, 8.04%). The operation time of the study group was (73.12 ± 12.23) min, there was longer than that in control group [(69.24 ± 11.54) min], but the difference was not statistically significant (P > 0.05); The average hospital stay in the study group was (3.85 ± 0.98) d, it was shorter than that in control group [(5.04 ± 1.24) d]; The overall incidence of postoperative complications and postoperative bleeding in the study group were lower than that in control group, the differences were statistically significant (P < 0.05). The hospitalization expenses was (23 728.85 ± 3 916.89) yuan in the study group, there were more than that in control group (22 820.84 ± 5 051.80) yuan, but the difference was not statistically significant (P > 0.05); There was no significant difference in the incidence of postoperative perforation, fever, abdominal pain, and abdominal distension between the two groups (P > 0.05).Conclusion Single forcep endoscopic purse-string suture can effectively close the wound of colorectal lesions after ESD, shorten the postoperative hospital stay, reduce postoperative bleeding and the overall risk of postoperative complications. This method is safe, does not increase the overall hospitalization costs, and is suitable for clinical application and promotion.
