Revisional Gastric Bypass After Failed Adjustable Gastric Banding-One-Stage or Two-Stage Procedure?

Area of Science:

• Bariatric Surgery
• Surgical Outcomes
• Gastrointestinal Surgery

Background:

• Revisional laparoscopic Roux-en-Y gastric bypass (R-LRYGB) is the standard procedure following adjustable gastric banding failure.
• Limited data exists comparing one-stage (band removal and R-LRYGB) versus two-stage (separate procedures) approaches.

Purpose of the Study:

• To compare the early and long-term outcomes of one-stage versus two-stage R-LRYGB procedures.
• To evaluate the efficacy and safety of both surgical approaches at a single institution.

Main Methods:

• Retrospective analysis of 165 patients undergoing R-LRYGB.
• Patients were divided into one-stage (n=98) and two-stage (n=67) groups.
• Analysis included indications, operative time, complications, morbidity, mortality, and length of stay (LOS).

Main Results:

• No significant differences were observed in operative time, LOS, or mortality between the one-stage and two-stage groups.
• Major complication rates were similar (15.3% one-stage vs. 16.9% two-stage).
• Indications differed, with weight regain more common in the one-stage group and band erosion in the two-stage group.

Conclusions:

• Both one-stage and two-stage R-LRYGB achieve good outcomes after adjustable gastric banding failure.
• The one-stage approach is preferred due to reduced costs and shorter LOS by avoiding an additional surgery.
