摘要

Background

Laparoscopic sleeve gastrectomy (LSG) has become one of the most commonly performed bariatric procedures. Among the various surgical approaches, the left-sided sleeve gastrectomy (LS-SG) offers potential advantages in terms of easy access to the anatomical region, operative time, and low complication rates.

Methods

We retrospectively analyzed data from 728 patients who underwent LS-SG between November 2018 and November 2019. The surgical technique consists of the use of three ports positioned on the left side of the abdomen, allowing good visualization of the stomach and adequate stapler positioning. Operative time, complication rates, and length of hospital stay were recorded.

Results

Among 728 patients (18.63% male, 81.37% female; mean age: 40 years), the mean operative time was 25 min (range 15–70). All patients were discharged after 2 days, except for one who required post-operative transfusion. One patient out of 728 (0.1%) developed a gastric fistula 5 days after being discharged.

Conclusions

LS-SG is a safe, reproducible, and efficient technique for performing LSG. It offers the advantages of improved anatomical exposure, reduced operative time, and low complication rates.
