Postoperative outcomes following inguinal hernia repair in inflammatory bowel disease patients compared to matched...

To assess surgical outcome in inflammatory bowel disease (IBD) patients who underwent inguinal hernia repair and to asses possible risk factors.

A retrospective analysis of a prospective database including all IBD patients treated in a large tertiary center between 2008 and 2019 was conducted. IBD patients who underwent inguinal hernia surgery were matched using a propensity match scoring based on demographic and perioperative characteristics. Clinical operative data were extracted from medical records and analyzed.

Overall, out of 5467 IBD patients treated in our institute, 26 patients (0.47%) underwent inguinal hernia repair. Seventy-six matched patients with similar characteristics were compared to the IBD group. Postoperative complications were found to be more common in the IBD group (30.7% vs 11.8%; P = 0.03) compared to controls. We found no significant differences in length of stay (3.38 vs 2.83 days; P = 0.21) and hernia recurrence rate (7.6% vs 9.2%; P = 1). Within the IBD group, multivariate analysis failed to demonstrate any possible risk factor for postoperative complications, including gender [-1.53 to 2.81 95% confidence interval (CI), P = 0.52], age (-0.34 to 1.15 95% CI, P = 0.25), BMI (-0.041 to 0.019 95% CI, P = 0.43), American Society of Anesthesiologists score (-0.15 to 0.54 95% CI, P = 0.24) or medications (-0.25 to 0.28 95% CI, P = 0.88). In addition, out of various operative factors, including operation urgency, surgical approach and surgery duration, only the latter was found to be correlated with postoperative complications (0.013-0.035 95% CI, P < 0.001).
