METHODS: We propose a single-institute, prospective, randomized, blinded-endpoint trial to assess the superiority of the combination of continuous suturing of the fascia without peritoneal closure and continuous suturing of the subcuticular tissue (study group) over that of interrupted suturing of the fascia together with the peritoneum and interrupted suturing of the subcuticular tissue (control group) for reducing the incidence of midline abdominal wall incision wound complications after elective gastroenterological surgery with a clean-contaminated wound. Permuted-block randomization with an allocation ratio of 1:1 and blocking will be used. We hypothesize that the study group will show a 50% reduction in the incidence of wound complications. The target number of cases is set at 284. The primary outcome is the incidence of wound complications, including incisional surgical site infection, hemorrhage, seroma, wound dehiscence within 30 days after surgery, and incisional hernia at approximately 1 year after surgery.
CONCLUSIONS: This trial will provide initial evidence on the ideal combination of fascial and skin closure for midline abdominal wall incision to reduce the incidence of overall postoperative wound complications after gastroenterological surgery with a clean-contaminated wound. This trial is expected to generate high-quality evidence that supports the current guidelines for the closure of abdominal wall incisions from the European and American Hernia Societies and to contribute to their next updates.

方法:我们提出了一个单一的研究所,prospective,随机化,盲法-终点试验旨在评估不闭合腹膜的筋膜连续缝合和表皮下组织连续缝合(研究组)在减少选择性胃肠手术和清洁污染伤口后中线腹壁切口并发症发生率方面的优越性。将使用分配比率为1:1和阻塞的置换块随机化。我们假设研究组将显示伤口并发症的发生率降低50%。病例的目标数量设定在284。主要结果是伤口并发症的发生率,包括手术切口感染,出血,血清肿,手术后30天内伤口裂开,手术后大约1年的切口疝。
结论:该试验将为中线腹壁切口筋膜和皮肤闭合的理想组合提供初步证据,以减少清洁污染伤口的胃肠手术后整体术后伤口并发症的发生率。预计该试验将产生高质量的证据,以支持欧洲和美国疝协会关于关闭腹壁切口的当前指南,并有助于他们的下一次更新。
