چکیده
BACKGROUND/AIMS The goal of this study was to analyze the likelihood of patients undergoing Roux-en-Y gastric bypass (RYGB) to recover a normal daily food intake, and the possible influence of dietary and exercise habits on long-term weight loss. METHODS The sample included 107 morbidly obese postoperative patients with at least 1 year of follow-up. The data collected included anthropometry, dietary and exercise habits, and information on ingested food. The unpaired Student's t test and the multivariate step-by-step regression were used in the analysis. RESULTS The mean preoperative BMI was 50.7 ± 11.8 kg/m(2), which had decreased at the moment of survey to 31.7 ± 5.4 kg/m(2). The mean % Excess of BMI Lost (%EBMIL) was 77.4 ± 23.7%. The nutritional components of diet were similar to those for the nonobese population. There were no significant differences in %EBMIL regarding number of meals, social habits, components of diet, or amount of exercise. The daily mean caloric intake (1,364 ± 293 kcal) was the only parameter significantly related to the %EBMIL outcome. More than 30% of the patients had intolerance to certain foods. CONCLUSION Obese patients undergoing RYGB can establish a postoperative lifestyle and diet similar to the ideal. Only the daily amount of ingested calories demonstrated a statistically significant influence on weight loss over time.

Safety and effectiveness of bariatric surgery: Roux-en-Y gastric bypass is superior to gastric banding in the management of morbidly obese patients
BACKGROUND The use of bariatric surgery in the management of morbid obesity is rapidly increasing. The two most frequently performed procedures are laparoscopic Roux-en-Y bypass and laparoscopic gastric banding. The objective of this short overview is to provide a critical appraisal of the most relevant scientific evidence comparing laparoscopic gastric banding versus laparoscopic Roux-en-Y byp...

BACKGROUND The positive impact of Roux-en-Y gastric bypass on weight, comorbidities, and health-related quality of life is well documented. However, 50 percent of patients regain some of the lost weight after 2 years with Roux-en-Y gastric bypass and present a mean weight regain of 10 to 15 percent after several years, partially losing the previously obtained benefits. The authors hypothesize t...

We report a case of a Roux-en-Y gastric bypass (RYGB) in a morbidly obese patient with situs inversus totalis. Current experience with bariatric surgery in patients with situs inversus totalis shows that they can be operated on safely. The open approach in this case of a difficult anatomy may be beneficial and safer for the patient. The technique itself requires only minor modifications. The re...
