A randomized comparison of continuous versus interrupted mass closure of midline incisions in patients with gynecologic cancer

Objective: To address the incidence of deep wound dehiscence and incisional hernia formation with two types of mass closure after vertical midline laparotomy performed in patients with gynecologic cancer. Methods: Continuous and interrupted mass closures were compared randomly in 632 patients. Both methods were performed with absorbable material. Of the 614 subjects who could be evaluated, 308 underwent a continuous, non-locking closure with looped polyglyconate suture, and 306 were closed with interrupted polyglycolic acid according to the Smead-Jones technique. Results: Three (1%) subjects with the continuous closure and five (1.6%) with the interrupted closure had an abdominal wound infection ( P = .50). One patient whose incision was closed with continuous suturing had a deep wound dehiscence (without evisceration). The follow-up period was 6 months to 3 years. No patient had evidence of chronic sinus drainage. Thirty-two (10.4%) of the patients who had the continuous closure and 45 (14.7%) of those who were closed with the interrupted method had evidence of incisional hernia ( P = .14). No hernia developed in any patient with a wound infection. Four (1.3%) hernias after the continuous closure and eight (2.6%) after the interrupted closure required surgical repair because of patient discomfort ( P = .38). Conclusion: The interrupted closure was not superior to the continuous closure for short- and long-term wound security. The continuous method was preferable because it was more cost-efficient and faster.
