Laparoscopic Sleeve Gastrectomy with T-Shaped Omentoplasty: Impact on the Early Postoperative Outcomes.

PURPOSE Laparoscopic sleeve gastrectomy (LSG) is an effective bariatric procedure, yet can be followed by complications such as staple line leak and bleeding, vomiting, and gastroesophageal reflux disease (GERD). Various attempts have been described in the literature to improve the early outcome of LSG through various measures. This study aimed to assess the impact of adding T-shaped omentoplasty to LSG on the short-term outcome of the procedure. METHODS This was a retrospective cohort study on patients with morbid obesity who underwent LSG in the period of November 2015 to November 2018. The outcome of patients with morbid obesity who underwent LSG combined with T-shaped omentoplasty (group I) was compared with that of a similar number of patients who underwent classical LSG without staple line fixation (group II). The main outcome measures were the rates of staple line bleeding and leak, postoperative nausea and vomiting (PONV), GERD, gastric axial rotation, other complications, and weight loss. RESULTS The study included 106 patients of a mean BMI of 49.8 kg/m2. Group II had significantly higher PONV) scale at 1 week and 1 month than group I. Group I had significantly lower rates of staple line bleeding (0 vs 9.6%, p = 0.02) and GERD (3.7% vs 17.3%, p = 0.02) than group II. Both groups had similar rates of staple line leak and comparable operation time. CONCLUSION Staple line fixation using the T-shaped omentoplasty technique was associated with lower incidence of significant PONV, staple line bleeding, and GERD as compared with classical LSG.
