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.
