Retrospective Study for the Outcomes of Single Incision Laparoscopic Sleeve Gastrectomy for Treatment of Morbid Obesity

Background: LSG became very popular among all the community. Traditionally, it is performed through 3-5 incisions. SILSG is done through one incision, improving the aesthetic outcome. SILSG has some advantages over the conventional LSG which are less abdominal pain, less admission in hospital, and rapid return to work.  
Aim: In this study we are going to assess the safety and feasibility of SILSG in a group of patients and report the outcomes and complications.  
Materials and Methods: We collected the data of 50 consecutive patients with morbid obesity who underwent SILSG in our department from May 2017 till August 2018. The inclusion criteria were a body mass index (BMI) ≥40 or ≥35 kg/m2 associated with co-morbidities. The exclusion criteria were patients with a BMI >60 kg/m2, previous upper abdominal surgeries, large abdominal hernias, or large hiatus hernia.  
Results: 50 patients were included in our study. Their median age was 41 years, and 78% were females. The median BMI was 44.5 kg/m2. The median operating time was 72 minutes (range 56–145). There was no intraoperative complications. Six patients (12%) required 1 or 2 additional trocars. Only 6% had early complications. There was no cases of wound infection or incisional hernia. There was no conversion to open surgery or conventional LSG. There was no mortality. The mean reduction in excess weight was 68%. All patients were satisfied with their wound.  
Conclusion: SILSG is a safe and feasible technique if performed by an expert surgeon. It has low complication rates and no reported mortality. Randomized studies are still needed after improvement of the associated learning curve, to assess the long-term results.
