The application and effect of presuturing with clips in endoscopic full-thickness resection

There are few studies on presuturing for full-thickness resection. To explore the effect of using clips as a presuturing technique for endoscopic snare resection with an elastic band (ESR-EB). The clinical data of patients who underwent ESR-EB at Shenzhen Second People's Hospital between May 2023 and May 2024 were collected. The patients were divided into presuture and non-presuture groups according to whether tissues were stitched before resection. The general clinical characteristics, tumor growth position, tumor size, tumor growth pattern, pathological type, operation time, resection time, complication rate, number of clips, and postoperative antibiotic usage rate were compared. A total of 73 patients were enrolled, 55 of whom were included in the presuture group and 18 were included in the non-presuture group. There was no difference in age, sex, tumor position, tumor size, or tumor growth pattern between the 2 groups (P > .05). There was no significant difference between the 2 groups in terms of operation time, resection time, pathological diagnosis, number of clips, or complication rate (P > .05). Complete resection was achieved in all of the patients. The perforation diameter in the presuture group was significantly smaller than that in the non-presuture group ([3.20 ± 1.56] vs [4.67 ± 2.79], [P = .006]). Thirty-three (60%) patients in the presuture group and 16 (88.89%) patients in the non-presuture group received postoperative preventive antibiotics, and the difference between the 2 groups was significant (P = .024). Gastric myometrial lesions <10 mm in diameter can be completely removed via ESR-EB. Clips as a means of presuturing can significantly reduce the perforation diameter and the use of postoperative preventive antibiotics. Moreover, clips as a means of presuturing does not increase the total number of clips used for the procedure and therefore should be considered a feasible, safe and effective technique.
