Incidence and Risk Factors of Incisional Hernia After Single-Incision Endoscopic Surgery.

Introduction: Abdominal wall complications are one of the most controversial issues regarding single-incision endoscopic surgery. The aim of this study was to analyze the incidence and risk factors of incisional hernia after single-incision endoscopic cholecystectomy. Materials and Methods: An observational retrospective study was performed, on a cohort of patients cholecystectomized laparoscopically through a transumbilical single incision due to gallbladder lithiasis or polyps. Postoperative complications were analyzed, with special interest in the incisional hernia rate, whose results were assessed in the long-term follow-up. Univariate and multivariate analyses were also performed to evaluate possible variables associated with the appearance of incisional hernia. Cumulative sum charts (CUSUM) were used to identify trends in the incisional hernia risk. Results: Some 109 patients were included in the study. With a mean follow-up of nearly 38 months, an incisional hernia incidence of 5.5% was found, with 67% being diagnosed during the first year of follow-up. In the Cox regression analysis, two variables showed an independent association with the emergence of incisional hernia, body mass index (hazard ratio [HR] 1.30; 95% confidence interval [CI 1.053-1.606]; P .015), and wound infection (HR 26.32; [3.186-217.40]; P .002]. CUSUM charts showed a decrease in the risk of incisional hernia after the first 10 cases. Conclusions: Single-incision endoscopic cholecystectomy is associated with a substantially high risk of postoperative incisional hernia (5.5%).
