Abstract
Purpose
Laparoscopic adjustable gastric banding (LAGB) has declined in popularity due to poor weight loss and high revision rates. The study aim was to evaluate complication rates following LAGB removals, including conversions to other bariatric procedures.
Materials and Methods
This was a retrospective cohort study of patients who underwent LAGB removal, identified from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database from the Toronto Western Hospital site. Patients were filtered using principal procedure and concurrent procedural terminology (CPT) codes. Patients converted to other bariatric procedures were also included. Outcomes were evaluated for 30-day morbidity, mortality, readmissions, and costs.
Results
From 2012 to 2018, 93 patients met inclusion. 96.77% had elective surgery, and 3.23% were emergent. Thirty-day postoperative complication rate was 11.83%, with 4.30% readmissions and no deaths. Surgical site infections accounted for 81.82% of complications (54.55% superficial, 27.27% deep). Thirty-day complication rate for LAGB removal alone was 17.50% and 33.33% following emergent explantation. 56.99% LAGBs were converted to other bariatric procedures: 48.39% laparoscopic Roux-en-Y gastric bypass (LRYGB) and 8.6% sleeve gastrectomy (LSG). Conversion to LSG had a significantly higher 30-day complication rate (all Clavien–Dindo class I–II) compared to conversion to LRYGB (37.50% versus 2.22%, p < 0.009). Direct costs of LAGB explantation to the healthcare system were $665,443, amounting to $7,155 per patient.
Conclusion
Thirty-day complication rates for LAGB explantation and conversion to other bariatric procedures are significant and may be higher than previously reported for LAGB removal alone. Conversion to LSG may have the highest complication rate, amounting to significant costs.

Key Points
• Thirty-day complication rate following LAGB explantation was 11.83%.
• Conversion to LSG had the highest rate of complications.
• LAGB explantation cost our healthcare 7 K without complications and 13 K with complications, per patient.
