    Abstract:
    BACKGROUND: Obesity is recognized as a risk factor for trocar site hernia (TSH) after laparoscopic surgery. Some recent studies have reported a TSH rate after bariatric surgery ranging from 0% to 1.6% using clinical evaluation and may underestimate the TSH rate. The objective of this study was to evaluate the TSH rate after sleeve gastrectomy (SG) by abdominal computed tomography (CT) scan. METHODS: A retrospective review of all patients who underwent first-line SG and abdominal CT scan between March 2004 and February 2014 was performed. The primary endpoint was the incidence of TSH. Secondary endpoints were the site of TSH, the TSH rate with open laparoscopy using the authors' technique, and risk factors for TSH after SG. RESULTS: During the period study, 1108 patients underwent first-line SG, including 10 cases of conversion to laparotomy (excluded from the present analysis). Of the remaining patients, 228 had abdominal CT scan (20.7%), with a mean age of 45.1 years (18-68 yr) and a mean BMI of 47.6 kg/m(2) (33-75.4 kg/m(2)). The median time interval between SG and CT scan was 27 months (3-92 mo). CT scan revealed 44 TSH in 43 patients (18.8%). The site of the TSH was epigastric (16.6%), open laparoscopy (1.7%), right subcostal margin (0.8%), with no TSH in the left subcostal margin. In patients with>1 year of follow-up, the TSH rate was 19.7%. CONCLUSION: The TSH rate after bariatric surgery is underestimated. The authors' open laparoscopy technique is a reliable technique with a low TSH rate. In the light of these results, the epigastric trocar site is systematically closed at the end of SG.
