Patients undergoing intragastric balloon achieve approximately 50% of their target weight loss in the first month postoperatively: an MBSAQIP analysis.

Abstract

Intragastric balloon (IGB) placement can provide a mean percent total weight loss (%TWL) of 10.2% at 6-month follow-up. We aimed to evaluate 30-day outcomes and safety of patients undergoing IGB placement. Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program. The 2016 to 2017 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program was queried for adult patients who underwent primary IGB placement. Demographic characteristics and preoperative risk factors were collected. Postoperative outcomes included %TWL, percent excess weight loss, and complications rates and causes. Subset analysis was done for outcomes comparison between surgeons or gastroenterologists performing the procedure. Statistical analysis was performed using SPSS 25.0. A total of 1221 patients were included. The majority was female (81.9%), Caucasian (81.2%), with a mean age of 48 ± 11.3 years and a mean preoperative body mass index of 34.9 ± 11.2 kg/m2. Of patients, 98.8% were discharged within 24 hours of the procedure. Two patients were admitted to the intensive care unit, and 7.2% received postoperative treatment for dehydration. Reoperation and readmission rates were 1.1% and 7.2%, respectively, mainly due to nausea, vomiting, and poor nutritional status (n = 22). The intervention rate was 6.2%. Patients in this cohort achieved a mean %TWL of 6.2% (standard deviation, 5.52%) and mean TWL of 6.8 kg within 30 days postoperatively (n = 147; 24-30 d). Our data show patients met approximately 50% of their target weight loss 30 days after IGB placement. Nausea, vomiting, and poor nutrition status were the most common complications within 30 days of the procedure. Long-term follow-up is necessary to determine if these patients are able to sustain their weight loss and for how long.
