EVALUATION OF THE FREQUENCY OF TROCAR SITE HERNIA AFTER LAPAROSCOPIC SLEEVE GASTRECTOMY

Abstract

Objective: Today, laparoscopic sleeve gastrectomy (LSG) has become the most frequently performed bariatric surgical method. One of the complications seen after LSG is trocar site hernia (TSH). There is no clear information about the rate of TSH detected radiologically after LSG. A thick abdominal wall and the failure to adequately expose the fascial defect related to this, as well as mobility limitations due to excessive subcutaneous fatty tissue, are the reasons for increased incidence of TSH. Materials and Methods: The demographic characteristics and postoperative weight loss of patients who underwent LSG procedures and whose fascial defects in the trocar region were repaired with the Carter-Thomason Suture Passer (CTSP) in our clinic between January 2015 and June 2017 were evaluated. TSH evaluation was performed both through physical examination and superficial USG by a general surgeon who had radiological training on concurrent superficial abdominal ultrasonography (USG). Detected TSHs were divided into two groups: symptomatic and asymptomatic. Results: A total of 61 patients were included in the study. The mean period after operation was calculated as 36 months (min 20, max 52). TSH was detected in seven (11.5%) of 61 patients, two of whom had symptomatic and five of whom had asymptomatic TSH. Being over 40 years of age and having a calculated body mass index (BMI) value greater than 30 kg/m2 during measurement were found to be the factors that significantly increased the incidence of TSH (p<0.05). Conclusions: Advanced age and inadequate weight loss are the factors that increase the rate of TSH after Sleeve Gastrectomy.
