Comparative study of postoperative complications after open and laparoscopic surgery of the perforated peptic ulcer: Advantages of the laparoscopic approach

Abstract

Background: Despite the acceptance of the laparoscopic approach for the treatment of perforated peptic ulcers, its definitive implantation is still a matter of discussion. We performed a comparative study between the open and laparoscopic approach focused on postoperative surgical complications. Methods: Retrospective observational study in which patients operated on for perforated peptic ulcus in our center between 2001 and 2017 were analyzed. Only those in whom suture and/or omentoplasty had been performed were selected, either for open or laparoscopic approach. Demographic, clinical, and intraoperative variables, complications, mortality and length of stay were collected. Both groups, open and laparoscopic surgery patients, were compared. Results: The final study sample was 250 patients, 190 (76%) men and 60 (24%) women, mean age 54 years (SD ± 16.7). In 129 cases (52%), the surgical approach was open, and in 121 (48%) it was laparoscopic. Grades III-V complications of the Clavien-Dindo Classification occurred in 23 cases (9%). Operative mortality was 1.2% (3 patients). Laparoscopically operated patients had significantly fewer complications (p = 0.001) and shorter hospital stay (p < 0.001). In multivariate analysis, laparoscopic approach (p = 0.025; OR:0.45–95%CI: 0.22–0.91), age (p = 0.003; OR:1.03–95%CI: 1.01–1.06), and Boey score (p = 0.024 – OR:1.71 – CI95%: 1.07–2.72), were independent prognostic factors for postoperative surgical complications. Conclusion: Laparoscopic surgery should be considered the first-choice approach for patients with perforated peptic ulcer. It is significantly associated with fewer postoperative complications and a shorter hospital stay than the open approach.
