Task: Answer Verification
Input (English): Question: Does preoperative weight gain predict failure of weight loss or co-morbidity resolution of laparoscopic Roux-en-Y gastric bypass for morbid obesity?
Answer: The results of our study have shown that weight loss before laparoscopic Roux-en-Y gastric bypass is not mandatory and might deter patients from considering weight loss surgery. Laparoscopic Roux-en-Y gastric bypass can be performed safely with equivalent co-morbidity resolution and %EWL regardless of PWG or PWL.
Output (English): no
