Gastric Bypass as a Third Bariatric Procedure—Our Experience with 42 Cases
- 32 Downloads
It is not uncommon to encounter patients seeking a third, fourth, or even fifth bariatric procedure. With higher expected complication rates and questionable patient benefit, the indication for multiple revisions is still in doubt. To evaluate the perioperative and post-operative outcomes of patients undergoing gastric bypass after two previous bariatric surgeries or more.
We identified all patients that underwent gastric bypass following at least 2 previous bariatric surgeries. We looked at patient demographics, previous bariatric surgeries, pre-operative body mass index (BMI) and obesity-related co-morbidities, perioperative complications, length of stay (LOS), re-admissions and re-operations, percentage of excess weight loss, and resolution or improvement in comorbidities.
Forty-two patients met the inclusion criteria, the majority being females (31, 73.8%). Average age was 45.6 years (range 27–62), average weight and BMI was 116 kg (range 75–175 kg) and 41.1 kg/m2 (range 25.6–58.7 kg/m2), respectively. Thirty-two patients had two previous bariatric surgeries (73.8%), and 10 patients had 3 former bariatric surgeries (23.8%), and for one patient, this was the fifth bariatric procedure (2.4%). Mean LOS was 10 days (range 2–56 days). Eight patients (19%) needed re-admission and 5 (11.9%) needed re-operation. At a median follow up of 48 months (range 7–99 months), the average BMI was 34.5 kg/m2 (range 23.7–55.1 kg/m2) reflecting an excess BMI loss of 43.3%.
Gastric bypass as a third or more bariatric procedure is effective yet associated with high complication rates, re-admissions, and re-operations.
