Outpatient gastroplasty for morbid obesity: our first hundred cases

Abstract

Background: Laparoscopic adjustable gastric banding (LAGB) is a safe and effective treatment for morbid obesity. The aim of the present study was to identify factors actually contributing to the feasibility or to the failure of performing this procedure in an outpatient setting.

Methods: In this prospective study, 100 ambulatory LAGB procedures were compared with 100 procedures performed in patients with an overnight stay. The recorded variables in both groups were first compared by univariate analysis. Logistic regressions were then calculated to analyse which of the variables were independently predictive.

Results: The mean time lapse between the end of surgery and discharge from hospital was 8.33 h in the outpatient group and no patient required readmission. Independent risk factors affecting same-day discharge were increasing age of the patient, higher BMI and diabetes. Other variables such as patient's gender, duration of surgery, distance home-hospital, number of previous abdominal procedures and other comorbidities did not demonstrate statistical differences between the two study groups.

Conclusion: Gastric banding for the treatment of obesity can be safely performed in an outpatient setting. Advanced age, higher BMI and diabetes adversely affect same-day discharge and should be taken into consideration when planning an ambulatory LAGB.
