BACKGROUND: No study has surveyed the factors that influence morbidly obese patients' preference for a particular bariatric operation. METHOD: 469 consecutive patients in 2 major bariatric surgery centers in the United States (US, 124) and Australia (AU, 345) were prospectively studied to determine referral pattern and reason for their choice of operation. RESULTS: The predominant operation was laparoscopic adjustable gastric banding (LAGB) in both US (75%) and AU (83%) centers. Gender (70% female), BMI (45 kg/m2) and age (42.5 years) were similar in both cohorts. In Australia, 53% had referral initiated by primary doctors and 25% by another patient, while in the US, 43% by another patient and 27% by the Internet. Safety of the operation (43%) was the highest-rated factor in choosing LAGB. LAGB being "least invasive" was most significant in the US (46%), and "surgical safety" in Australia (45%). In the US, Rouxen-Y gastric bypass was preferred due to "lack of a foreign body" (31%) and "inability to cheat" (28%), while in Australia, "dumping" was the most significant reason (50%). Duodenal switch (BPD/DS) was selected in 11% of patients, primarily because of "durability of the weight loss" (51%). Surprisingly, only 1 patient in the US group selected BPD/DS because the pylorus remains intact. CONCLUSION: Safety and invasiveness had the greatest impact on patient choice for bariatric operation in two different countries. This information may help clinicians better understand their patients' concerns, and their treatment choices.
