Background
Prophylactic mesh closure has only scarcely been studied to avoid extraction-site incisional hernia after laparoscopic colorectal surgery. The aim was to analyze extraction-site incisional hernia incidence after laparoscopic colorectal surgery to assess if prophylactic mesh closure should be studied.
Methods
A retrospective analytic cohort study was conducted in patients who had undergone laparoscopic colorectal surgery with an extraction-site incision. Extraction-site incisional hernia was diagnosed during clinical examination or imaging. Risk factors for extraction-site incisional hernia were analyzed.
Results
Two hundred and twenty-five patients were included. More than 80% of the patients had a malignant disease. Ninety-two patients (40.9%) underwent right colectomy. Midline extraction-site incision was used in 86 (38.2%) patients. After a mean follow-up of 2.4 years, 39 (17.3%) patients developed an extraction-site incisional hernia. Midline extraction-site incision was associated with incisional hernia when compared to transverse and Pfannenstiel incision (39.5% vs. 3.6%, OR 17.5, p < 0.001). Surgery to repair an extraction-site incisional hernia was also more frequent in the group of patients with a midline incision (10.5% vs. 1.4%, OR 8.0, p = 0.002). In the multivariate analysis, incisional hernia was associated with body mass index, high blood pressure, and midline incision.
Conclusions
Extraction-site incisional hernia was mainly related to midline incisions; therefore, midline incision should be avoided whenever possible. Studying prophylactic mesh closure for Pfannesnstiel or transverse incisions is needless, as these incisions have a low incisional hernia risk.
