Roux-en-Y gastric bypass after failed vertical banded gastroplasty.

Area of Science:

• Bariatric Surgery
• Gastrointestinal Surgery
• Obesity Treatment

Background:

• Vertical banded gastroplasty (VBG) was a common bariatric procedure but is associated with high long-term failure rates.
• VBG failure can manifest as insufficient weight loss or procedure-related complications.
• Revision bariatric surgery, specifically conversion to Roux-en-Y gastric bypass (RYGBP), is explored for failed VBG.

Purpose of the Study:

• To review the experience of converting failed vertical banded gastroplasty (VBG) to Roux-en-Y gastric bypass (RYGBP).
• To evaluate the effectiveness and safety of VBG to RYGBP conversion in terms of weight loss and complication management.

Main Methods:

• Retrospective review of patients undergoing conversion from failed VBG to RYGBP.
• Failed VBG defined by insufficient weight loss (BMI > 35 kg/m2) or VBG-related complications.
• Data collected included patient demographics, indications for conversion, surgical approach (laparoscopic or open), need for gastrectomy, postoperative complications, and weight loss outcomes.

Main Results:

• Twenty-four patients underwent VBG to RYGBP conversion, with indications including VBG failure (18 patients) and complications (6 patients).
• The procedure was performed laparoscopically in 13 cases; 5 patients (21%) required gastrectomy.
• Postoperative complications occurred in 16.7% of patients, with no reported leaks or mortality. At 12 months follow-up, the average excess weight loss was 62%, with a postoperative BMI of 31 kg/m2.

Conclusions:

• Conversion of failed VBG to RYGBP is an effective strategy for achieving significant weight loss and managing VBG-related complications.
• The conversion procedure is technically feasible, with acceptable morbidity and no mortality, and can be safely performed laparoscopically.
• Surgical techniques like gastrectomy and staple-line resection may help mitigate complications such as leaks and mucocele formation.
