Impact of smoking and age on long-term recurrence after laparoscopic primary closure for duodenal ulcer perforation: a 5-year observational study.

PURPOSE: This study investigates risk factors for recurrence in patients who underwent laparoscopic primary closure (PC) for pyloroduodenal ulcer perforation (PUP).

METHODS

We retrospectively analyzed data from patients who underwent laparoscopic PC with or without highly selective vagotomy (HSV) for PUP at a tertiary hospital from 2010 to 2019. Demographics, surgical outcomes, proton pump inhibitor (PPI) use, Helicobacter pylori status, and endoscopic findings were reviewed. Long-term (5 years) endoscopic and clinical outcomes regarding ulcer and perforation recurrence, were collected.

RESULTS

A total of 139 patients were included in the analysis. Of these, 109 (78.4%) were male, and 76 (54.7%) were current smokers. Ninety-five patients (68.3%) underwent PC only, while 44 (31.7%) received PC + HSV. During the follow-up period, ulcer recurrence was observed in 19 patients (13.7%) and perforation recurrence in 9 (6.5%). In Cox proportional analysis for ulcer recurrence, smoking (hazard ratio [HR], 6.476; 95% confidence interval [CI], 1.834-22.873; P = 0.004) and older age (HR, 1.049; 95% CI, 1.012-1.088; P = 0.009) were identified as significant factors. For peptic ulcer perforation recurrence, smoking (HR, 19.129; 95% CI, 2.048-178.702; P = 0.010) and older age (HR, 1.062; 95% CI, 1.009-1.118; P = 0.021) were significant. No significant associations were found between sex, duration of PPI therapy, H. pylori eradication success, or surgery type and the risk of either ulcer or perforation recurrence.

CONCLUSION

Smoking and age are important factors for recurrence following laparoscopic PC for PUP. These findings emphasize the need for smoking cessation and close postoperative monitoring.
