Laparoscopic Roux-en-Y gastric bypass: comparison between hand-sewn and mechanical gastrojejunostomy

Area of Science:

• Bariatric Surgery
• Minimally Invasive Procedures
• Surgical Techniques

Background:

• Morbid obesity is a significant health concern requiring effective surgical interventions.
• Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a preferred bariatric procedure.
• Variations in gastrojejunostomy (GJA) construction exist, impacting outcomes.

Purpose of the Study:

• To compare the safety, efficacy, and cost-effectiveness of linear-stapled versus hand-sewn GJA in LRYGB.
• To evaluate differences in operative time, complications, and bariatric results between the two GJA techniques.

Main Methods:

• Retrospective analysis of 104 consecutive LRYGB patients from June 2006 to September 2008.
• Patients were divided into two groups: linear-stapled GJA (n=51) and hand-sewn GJA (n=53).
• Comparison of demographic data, surgical outcomes, complications, and bariatric results.

Main Results:

• No significant differences in mortality, conversion rates, reoperations, complications, GJA leakage/stricture, or bariatric outcomes.
• Hand-sewn GJA was associated with a significantly shorter operating time (160 min vs. 190 min, p=0.029).
• Hand-sewn GJA resulted in lower operating supply costs (approx. 100 Euros less).

Conclusions:

• Hand-sewn GJA is a safe and effective alternative to linear-stapled GJA in LRYGB.
• The hand-sewn technique offers comparable bariatric results with potential advantages in operative efficiency and cost.
• Surgeons can consider hand-sewn GJA based on patient outcomes and resource considerations.
