Predictive factors for extraction site hernia after laparoscopic right colectomy

Purpose: Incisional hernia at the extraction site (ESIH) is a common complication after laparoscopic colorectal resections. The aim of this study was to evaluate the prevalence and potential risk factors for ESIH in a large cohort study having standardized technique.

Methods: A cross-sectional study was performed including all patients who underwent elective laparoscopic right or extended right colectomy for cancer from November 2006 to October 2013 using a standard technique. All patients have been followed up for a minimum of 1 year with abdominal CT scan.

Results: A total of 292 patients were included with a median follow-up of 42 months. Twenty patients (6.8 %) developed ESIH. Obesity (odds ratio (OR) = 3.76, 95 % confidence interval (CI) 1.39-10.15; p = 0.009) and incision length (OR 2.86, 95 % CI 1.077-7.60; p = 0.035) significantly predisposed to the development of ESIH.

Conclusion: This study identified that the risk of ESIH is significant after colonic resections and there are several risk factors responsible for the development of ESIH.
