Abstract

Background: Laparoscopic mini-gastric bypass (MGB) is a bariatric procedure which is gaining popularity worldwide. The original Rutledge technique is known to have good outcomes, but this and other surgical procedures that involve the use of staplers are very expensive for use in low-income countries. For this reason, the laparoscopic band-separated gastric bypass was developed. This paper aimed to describe a modified MGB technique without the use of staplers.

Methods: We present a modification of the MGB with the use of an obstructive stapleless pouch and anastomosis (MGB-Ospanov procedure). The technique is based on our experience in 32 patients who underwent the procedure involving this technique between January 2016 and December 2018.

Results: As in the original Rutledge version that uses staples, a long conduit is created below the crow's foot, extending up to the angle of His. The main differences between the MGB-Ospanov procedure and the stapler technique are as follows: creation of a gastric pouch from the anterior wall of the stomach; non-use of staplers; non-intersection of the stomach; use of semi-absorbable (or absorbable) strips of mesh; use of gastroplication to obstruct the communication between the gastric pouch and the bypassed greater part of the stomach. Gastrojejunostomy is performed using a hand-sewn suture at 150-200 cm distal from the ligament of Treitz. The body mass index (kg/m2) was 26.36 ± 4.0 after surgery vs 41.6 ± 6.1 before surgery (P < 0.0001).

Conclusion: The MGB-Ospanov procedure with an obstructive stapleless pouch and hand-sewn anastomosis is more feasible and cheaper than the stapler technique. Not using staplers could potentially help in avoiding bleeding and leakage along the stapler line when creating a gastric pouch. However, further research is warranted to confirm these results.
