Abstract
BACKGROUND
This study aimed to evaluate the outcomes of 67 patients who underwent revisional bariatric surgeries over a 29-year period in a Brazilian public hospital.

METHODS
The records of all patients who underwent revisional bariatric surgery from January 1987 to December of 2016 at our hospital were analyzed for weight loss and complications. Descriptive statistics and paired t tests were computed.

RESULTS
Sixty-seven patients were included in the study. The primary surgeries previously performed on these patients were biliopancreatic diversion with duodenal switch (BPD-DS) (37 cases, 55.2%), jejunoileal bypass (JIB) (24 cases, 35.8%), sleeve gastrectomy (4 cases, 5.9%), Roux-en-Y gastric bypass (RYGB) (1 case, 1.5%), and laparoscopic adjustable gastric band (1 case, 1.5%). The indications for revisional surgery were as follows: malnutrition in 29 cases (43.3%), failure to lose weight in 27 cases (40.3%), weight regain in 5 cases (7.5%), and untreatable diarrhea in 6 cases (9.2%). Most revisional surgeries were performed using JIB or BPD-DS. Operative mortality was higher after the revisional procedures compared with that following the primary bariatric surgeries.

CONCLUSIONS
Most patients requiring a revisional surgery had undergone a primary BPD-DS or JIB. Severe and untreatable malnutrition and diarrhea were the main indications for the revisional procedures. RYGB produced significant and sustainable weight loss and exhibited a low risk of malnutrition or requiring revisional surgery.
