RESUMEN
BACKGROUND: For abdominal fascial closure, the choice of optimal suture material and appropriate suture technique are of paramount importance to prevent the incidence of incisional hernia. Although barbed sutures are widely used in various surgical fields, their safety and feasibility on abdominal fascial closure which requires the most tensile strength for security have not been established yet. METHODS: We conducted a prospective, single-arm, interventional clinical trial to present the postoperative outcomes of using barbed sutures in abdominal fascial closure between April 2021 and August 2021. Patients with colorectal cancer who underwent minimally invasive surgery in elective setting were included. For all participants, monofilament polydioxanone barbed suture, MONOFIX®, was used to secure the abdominal fasica. The primary outcome was the 1-year incidence of incisional hernia assessed by computed tomography. RESULTS: A total of 30 patients were included. The median fascial incision length and suture length were 6.5 cm (range, 6-7.5 cm) and 31 cm (range, 27.5-39.0 cm), respectively. The median procedure time of abdominal fascial closure was 4 min (range, 3-9 min). There was no incidence of unexpected event related to suturing including suture cutting, stopper separation from threads, and suture loosening. One case of superficial surgical site infection occurred during postoperative hospital stays. There was no fascial dehiscence, incisional hernia, and adhesive ileus during a median follow-up period of 17.5 months. CONCLUSION: Monofilament polydioxanone barbed suture, MONOFIX®, may be used safely and effectively on abdominal fascial closure. GOV NUMBER: NCT05872334.
