Band versus bypass: randomization and patients' choices and perceptions.
BACKGROUND
Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic adjustable gastric banding (LAGB) are becoming increasingly popular; however, little is understood about patients' motivational factors and reasons for choosing a particular procedure. This investigation explored patient choices and perceptions concerning LRYGB and LAGB.


METHODS
A survey was given to 120 consecutive patients who had undergone LRYGB or LAGB 3-24 months earlier. The survey was designed to ascertain why patients chose banding or bypass, and how they rated their surgical outcome.


RESULTS
A total of 101 patients responded (84%): 22 had undergone LAGB, 79 LRYGB. The top reason for choosing LRYGB was greater expectation of weight loss, whereas LAGB was chosen for its lower risk. Overall, 21% (18/84) of the patients were willing to be involved in a prospective randomized study of bariatric procedure choice. Six of 19 (32%) patients who underwent LAGB, but only 12 of the 65 (18%) who underwent LRYGB stated that they would be willing to accept randomization between the operations.


CONCLUSIONS
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.
