ROUX-EN-Y GASTRIC BYPASS - A 7-YEAR RETROSPECTIVE REVIEW OF 3855 PATIENTS

Background: 3855 patients undergoing Roux-en-Y gastric bypass for morbid obesity between 1988 and 1994 are presented. Methods: Ail patients were sent a standard questionnaire reflecting current weight, intervening complications and general health status and 1039 patients responded, Information gleaned from review of these questionnaires and a review of individual charts provided the data for this study. Results: Average weight loss at 1 year was 46 kg and at 5 years was 34.5 kg, Operative mortality was 0.18%, surgical morbidity rate was 3.4%, Average length of stay for patients hospitalized in 1994 was 3.6 days, The average operating time during that same year was 78 min, and the average hospital charges were $7250. Conclusions: Roux-en-Y gastric bypass can be performed with relative safety and acceptable morbidity, There is a demonstrable weight loss benefit which is maintained in the majority of patients over a period greater than 5 years, The expense and consumption of provider services are modest, and this procedure remains an excellent alternative for weight control among morbidly obese individuals.
