Failed restrictive surgery: is sleeve gastrectomy a good revisional procedure?

Area of Science:

• Bariatric Surgery
• Gastroenterology
• Surgical Innovation

Background:

• Restrictive bariatric procedures, including laparoscopic adjustable gastric banding (LAGB), non-adjustable gastric banding (NAGB), and vertical banded gastroplasty (VBG), can fail to achieve desired weight loss or lead to complications.
• Patients experiencing inadequate weight loss, weight regain, or device-related issues often seek alternative surgical solutions.

Purpose of the Study:

• To evaluate the safety and efficacy of converting failed restrictive bariatric procedures to laparoscopic sleeve gastrectomy (LSG).
• To assess post-conversion outcomes, including body mass index (BMI) and excess weight loss (EWL).

Main Methods:

• A prospective database of 32 patients who underwent conversion from failed restrictive procedures (LAGB, NAGB, VBG) to LSG was analyzed.
• Data collected included pre- and post-conversion BMI, EWL, complications, and length of hospital stay.
• Follow-up averaged 26 months, with statistical analysis of weight loss outcomes.

Main Results:

• The mean pre-conversion BMI was 42.69, decreasing to a mean of 33.3 post-conversion to LSG.
• Mean excess weight loss (EWL) improved from 10% pre-conversion to 60% post-conversion.
• One complication (contained leak) occurred, successfully treated with antibiotics; there was no mortality or conversion to open surgery.

Conclusions:

• Conversion to LSG from prior restrictive bariatric surgery is a feasible and acceptable option for patients.
• LSG offers significant improvements in weight loss and BMI for patients with failed restrictive procedures.
• The procedure demonstrates a favorable safety profile with minimal complications.
