Objective:

This study aims to analyze and identify risk factors for postoperative complications and analyze the relative risk of reoperation for recurrence for respective complication.

Background:

The outcome of groin hernia surgery is evaluated mostly by comparing recurrence rates and long-term pain. The aim of this observational population-based registry study was to identify risk factors for postoperative complications and analyze the relative risk of reoperation for recurrence for respective complication.

Methods:

Using data from the nationwide Swedish Hernia Register between 1998 and 2009, 150,514 herniorrhaphies were analyzed with respect to postoperative complications occurring within 30 days of surgery.

Results:

Risk factors significantly affecting the rate of postoperative complications were laparoscopic repair (odds ratio [OR] 1.35, 95% confidence interval [CI] 1.24–1.47) and open preperitoneal techniques …
