Summary

The second branch of the right gastroepiploic artery, located approximately 4.5 cm from the pylorus, serves as a reliable landmark for vertical sleeve gastrectomy standardization. This finding helps surgeons consistently determine the distal resection margin during bariatric surgery.

Area of Science:

  • Bariatric Surgery
  • Surgical Anatomy
  • Gastrointestinal Surgery

Background:

  • Vertical sleeve gastrectomy is a prevalent bariatric procedure with variations in surgical technique.
  • Key variations include bougie size and the extent of distal resection, with some surgeons resecting 2 cm from the pylorus and others 6 cm.

Purpose of the Study:

  • To identify constant anatomic landmarks for standardizing vertical sleeve gastrectomy.
  • To evaluate the reliability of the second branch of the right gastroepiploic artery as a landmark.

Main Methods:

  • A study measured the distance from the pylorus to the second branch of the right gastroepiploic artery in 28 morbidly obese patients undergoing laparoscopic bariatric surgery.
  • Patient demographics including BMI, height, weight, age, and sex were also analyzed.

Main Results:

  • The mean distance from the pylorus to the second branch of the right gastroepiploic artery was 4.52 cm (range, 3.5-5.5 cm).
  • The study included 22 women and 6 men with a mean BMI of 43.2 kg/m².

Conclusions:

  • The second branch of the right gastroepiploic artery is a consistent anatomic landmark approximately 4.5 cm from the pylorus.
  • This landmark can be safely utilized to standardize the distal resection margin in vertical sleeve gastrectomy, eliminating the need for formal measurement.
