No results posted yet for this study

Summary

Aim: The impact of extended antral resection (AR) after laparoscopic sleeve gastrectomy (LSG) on weight loss changes and metabolic response is still not clearly elucidated with conflicting results. The investigator's retrospective cohort study aimed to determine whether AR is superior to antral preservation (AP) regarding weight loss and resolution of co-morbidities.

Methods: Patients were divided into two groups according to the distance of gastric division as AR group (2cm from pylorus) and AP group (6cm from pylorus). Postoperative excess weight loss percentile (%EWL) and total body weight loss percentiles (%TBWL) at the end of first, 6th and 12 months were compared. Secondly, metabolic parameters and complications were compared.

Interventions

PROCEDURE

laparoscopic sleeve gastrectomy

The greater omentum is carefully dissected from the stomach at a distance of 2cm for the patients with AR, and 6cm for patients with AP. The omental dissection was performed using 5mm-abdominal ligature (Ligasure®, Metronic-Covidien, Minneapolis, USA), from the antrum towards the angle of His. Transection from the omentum is continued until the left crus has been identified. All sleeves are transected using 36 French orogastric tubes. Green cartridges (4.8 mm staple height) are used for the first firing and blue cartridges (3.5 mm) for the rest. Neither oversewing sutures to the staple line nor staple line reinforcement products are used. Homeostatic metallic clips are used for bleeding at the staple line. If bleeding persists and cannot be controlled, an interrupted suture is performed at the point of bleeding. A leak test with methylene blue is performed to the gastric remnant to assess the integrity of the suture line.
