Abstract:

This article reports the clinical cases of three patients who underwent single-incision laparoscopic sleeve gastrectomy （SILSG） in the General Surgery Department of Beijing Luhe Hospital，Capital Medical University， in April 2024.All three patients underwent surgery with the in-situ division of the proximal stomach via a middle approach.The average age of the three patients was （40.3±2.1） years；preoperative weight was （85.2±5.3） kg； height was （1.62±0.03） m； and BMI was （32.6±2.4） kg/m².All surgeries were performed successfully without conversion to multi-port surgery.The average operation time was （145.0±18.0） minutes； intraoperative blood loss ranged from 10 to 20 mL.Postoperative recovery was uneventful， with no complications such as intra-abdominal bleeding， gastric leakage， or wound infection.Follow-up at 1， 3， and 6 months postoperatively showed satisfactory weight loss and no significant symptoms of acid reflux or heartburn.These preliminary results suggest that the surgical approach of the in-situ division of the proximal stomach via a middle approach is safe and feasible for SILSG， but further long-term followup of more cases is needed to confirm its safety and long-term efficacy.
