Writing in the American Journal of Surgery, Dr James D. Evans and colleagues examined the safety and effectiveness of laparoscopic adjustable gastric banding (LAGB) in 95 consecutive patients with morbid obesity.
The patients ranged in age between 19 and 69 years, with a mean age of 38. 89 of them were female.
Median weight and body mass index were 123.2 (88.9 to 228.6) kg and 45 (32.7-76.4) kg/m2 respectively.
Significant coexistent disease was present in 52 (55%) patients.
Following completion of the procedure, patients were followed up for 2 years, with weight loss and early and late complications being recorded.
The researchers found median excess weight loss was 53% (range 96.9% to 12.1%) and 62% (range 107.5% to 32.3%) at 1 and 2 years respectively.
Median operative time was 90 (range 35 to 285) minutes and in-patient stay 2 (range 1 to 10) days.
A total of 17 patients (18%) exhibited early complications following LAGB, most commonly nausea and vomiting, or dysphagia.

A slightly higher proportion of the study group also went on to experience late complications (25 patients, 26%), including vomiting or reflux due to band slippage or pouch dilatation.
There was 1 (1%) operative death.
Despite this, the authors conclude that LAGB is an effective operation for morbid obesity, adding that it results in equivalent weight loss to open surgery procedures.
