Outpatient Laparoscopic Adjustable Gastric Banding in Super-obese Patients

Background

Laparoscopic adjustable gastric banding (LAGB) is a safe and effective treatment for morbid obesity that is well suited to outpatient surgery. Super-obese patients (BMI ≥50) are often viewed as higher risk patients, with their surgical procedures limited to hospital operating-rooms. We report our experience performing LAGB for super-obese patients in a freestanding ambulatory surgery center and describe the program elements that make this feasible and safe.

Methods

Database records containing 1,780 consecutive patients from program inception (November 2002 to November 2006) were searched for patients with a BMI >49.9 undergoing an outpatient LAGB and reviewed to identify complications.

Results

320 super-obese patients underwent an outpatient LAGB.Mean preoperative weight was 155.2 kg (range 112.3–220.5 kg), and mean BMI was 55.4 kg/m² (range 50.0–71.1 kg/m²). 53 patients (16.6%) had BMI >60. There were no deaths, significant cardiopulmonary complications, significant intraoperative bleeding, conversion to open laparotomy, or hospital admissions. 3 patients (0.1%) developed gastric edema causing transient obstruction, and 1 developed a delayed colon perforation from electrocautery incurred during adhesiolysis. No complication arose or was more difficult to manage as a result of the procedure being done on an outpatient basis.

Conclusions

Outpatient LAGB can be safely performed in super-obese patients with a complication rate similar to lower BMI patients. Patient selection and preoperative preparation are essential to achieve excellent outcomes. The decision to offer an outpatient LAGB should rest on the overall physiological condition rather than BMI or weight alone.
