Background: Ineffective weight loss or complications of previous bariatric surgery often require revisional bariatric procedures. Our aim was to define the indications, operative approach, and outcomes of revisional bariatric procedures during 2 decades at a tertiary center. Methods: From our prospective database (n = 1584), including 1985-2004, 218 patients (14%) underwent revisional bariatric procedures. Follow-up (mean 7 yr, range 1 mo to 19 yr) data obtained from patient records and questionnaires were current for 98%. Patients were grouped according to operative indications: group 1, unsatisfactory weight loss (n = 97); group 2, mechanical/symptomatic complications (n = 95); and group 3, severe nutritional/metabolic problems (n = 26). Results: The operative mortality rate was 0.9% (1 case each of pulmonary embolus and cardiac arrest). The serious operative morbidity rate was 26% (wound infection in 13%, leak in 3%, pulmonary embolus in 2%, anemia/hemorrhage in 2%, pneumonia/prolonged ventilation in 2%, and other in 4%). Of the 218 patients, 94% underwent conversion to, or revision of, Roux-en-y gastric bypass. Group 1 achieved substantial weight reduction with a mean body mass index from 51 ± 1 to 38 ± 1 kg/m2, the complications resolved in 88% of group 2, and the nutritional/metabolic problems resolved in 79% of group 3. Patients who underwent revisional surgery 1990 were more likely to present with mechanical/symptomatic/metabolic complications than for unsuccessful weight loss (P <.001). Conclusions: Revisional bariatric surgery is safe and effective in experienced centers. Complications (mechanical/symptomatic/nutritional) or unsatisfactory weight loss after primary bariatric procedures can be treated effectively with revision to Roux-en-y gastric bypass.
