Band versus bypass: randomization and patients' choices and perceptions

Patients expressed varied reasons for choosing their procedure, most related to weight loss or safety profiles. Patients undergoing LAGB would have predicted similar results with either procedure, whereas those undergoing LRYGB showed a trend toward greater overall satisfaction with their operations (p = 0.06) and would have predicted an inferior outcome with the other procedure. Although the overall percentage of patients willing to be randomized is not high, a busy bariatric practice could recruit sufficient numbers of willing patients to undergo a prospective randomized trial of LRYGB and LAGB.
