Laparoscopic bariatric operations can be technically challenging in massively obese patients. The potential of the intragastric balloon for preoperative weight reduction was evaluated in candidates for laparoscopic Roux-en-Y gastric bypass (LRYGBP) with super obesity.


From January 2004 to March 2005, 10 patients with super obesity who were potential candidates for LRYGBP were included in a prospective observational study. An intragastric balloon was placed endoscopically under general anesthesia. Patients were then followed by a multidisciplinary team until removal of the balloon after 6 months. Weight, BMI, and percent excess weight lost (%EWL) were monitored after 1, 3 and 6 months.


The 10 patients were all female with mean +/- SD age of 33+/-11 years (range 17-51). Initial weight was 175+/-25 kg (range 135-223) and initial BMI was 64+/-7 kg/m2 (range 59-78). After completion of 1, 3 and 6 months, weight, BMI, and %EWL reached respectively: 166+/-27 kg*, 165+/-27 kg*, and 169+/-26 kg*; 61.1+/-7.6 kg/m2*, 60.8+/-8.4 kg/m2*, and 61+/-8.2 kg/m2*; 9+/-5%, 10+/-7%, 7+/-6%. (*=P<0.01 vs preop).


In potential candidates for LRYGBP with super obesity, preoperative placement of an intragastric balloon can reduce the excess weight by 10% within 3 months. Extending this period failed to improve these results further.
