Objective: Body contouring surgery has become a steadily increasing part of weight loss treatment in the population of patients electing to undergo bariatric surgery. This study aims to elicit factors that can be used to prognosticate which bariatric surgery patients will choose to undergo body contouring procedures.
Methods: A database of 381 patients who underwent gastric bypass surgery between August 2002 and December 2005 was retrospectively reviewed. All patients with subsequent body contouring surgery (group I) were identified and compared with those without it (group II). Variables studied were age, gender, preoperative excess body weight, percent excess weight loss at 6 and 12 months, preoperative body mass index, and change in body mass index at 6 and 12 months.
Results: We identified 24 patients for group I and 168 patients for group II. Group I was significantly younger with a mean age of 36 ± 9 years than group II with a mean age of 41 ± 10 years (P = .023). Change in body mass index was significantly greater in group I with changes of 16.1 ± 4 and 13.82 ± 3 (P = .001) at 6 months and changes of 21.4 ± 6.6 and 17.39 ± 4.6 (P < .0001) at 12 months in group I and group II, respectively. Lastly, the percent excess weight loss at 12 months was significantly greater in group I with a mean percent excess weight loss of 70.1 ± 13.3 than in group II with a mean percent excess weight loss of 62 ± 16.6 (P = .0052).
Conclusions: Age, change in body mass index at 6 and 12 months, and percent excess weight loss at 12 month follow-up were useful predictive factors to determine which bariatric surgery patients ultimately underwent body contouring procedures.
