Risk factors associated with the development of trocar site hernia after laparoscopic bariatric-metabolic surgery

Abstract

The aim of this study investigate the effects of three laparoscopic bariatric-metabolic surgery (BMS) techniques [sleeve gastrectomy (SG), SG with transit bipartition (SG-TB), one anastomosis gastric by-pass (OAGB)] and patients’ sociodemographic and clinical features on trocar site hernia (TSH) development after laparoscopic BMS. This was a retrospective study conducted between January 2015 and February 2022. A total of 54 obese patients, 18 who developed TSH and 36 who did not develop TSH during follow-up after laparoscopic BMS, were included in the study. Mean age was 55.28 ± 7.98 years in the TSH group and 40.58 ± 11.47 years in the non-TSH group (p < 0.001). Seventeen (94.4%) of the TSH group and 23 (63.9%) of the non-TSH group were females (p = 0.021). TSH developed in 1 patient who underwent SG (5.6%), 1 patient who underwent OAGB (5.6%), and 16 patients who underwent SG-TB (88.9%). Multiple logistic regression analysis revealed that high age (p=0.018) and undergoing SG-TB (p=0.018) were independently associated with TSH development. In order to reduce TSH risk and to increase the chance for early diagnosis in patients with advanced age or SG-TB recipients, we believe that taking additional intraoperative precautions and performing closer follow-up will be necessary.
