Weight loss and dietary intake after vertical banded gastroplasty and Roux-en-Y gastric bypass.

摘要: OBJECTIVE. The purpose of this study was to learn whether preoperative eating habits can be used predict outcome after vertical banded gastroplasty (VBG) and Roux-en-Y gastric bypass (RYGB). BACKGROUND SUMMARY. Several independent randomized sequential studies have reported significantly greater weight loss RYGB in comparison with VBG. Although the mechanism responsible for both procedures is restriction intake rather than malabsorption, relationships between calorie intake, food preferences, postoperative are not well defined. METHODS. During past 5 years, 138 patients were prospectively selected either VBG or RYGB, based on their habits. All screened by a dietitian who determined total diet composition before recommending RYGB. Thirty VBG; remaining 108 classified as "sweets eaters" "snackers" had Detailed recall histories also performed at each visit. RESULTS. Early morbidity rate zero versus 3% There no deaths. Mean follow-up 39 +/- 11 months 38 14 peaked 74 23 lb 12 99 24 16 (p = 50% excess 100 < 0.0001). Milk/ice cream postoperatively underwent 6 0.003), whereas solid sweets during first 18 0.004). Revision 30 (20%) complications poor loss, only 2 required surgical revisions 0.001). CONCLUSIONS. These data show that adversely alters behavior toward soft, high-calorie foods, resulting problematic loss. Conversely, despite inferior high revision conjunction inconsistent has led us longer recommend treatment morbid obesity.
