Upper gastrointestinal swallow study following bariatric surgery: institutional review and review of the literature
Obesity Surgery, 05/16/2012Brockmeyer JR et al.
The results of the study show that a positive UGI study for stricture has a specificity of 100 %. In terms of leak, which offers a much higher risk of significant morbidity and mortality, UGI was unable to find any on postoperative days 1 or 2. Based on the results of this study, the institution has stopped completing routine UGI on POD 1 following bariatric surgery.
Radiograph reports were reviewed from the period of January 2005 to July 2010.
During that time, 129 patients underwent LRYGB, 209 underwent LS, and 12 patients underwent LAGB.
Of those patients, 120 LRYGB patients, 188 LS patients, and 11 LAGB patients underwent upper gastrointestinal studies on postoperative days (POD) 1 or 2.
Of the 319 total patients who underwent UGI, no contrast leaks were found.
One LRYGB patient was found to have stenosis of the jejunojejunal anastomosis and was taken to the operating room for revision.
A total of ten patients went on to develop leaks: four LRYGB patients, six LS patients, and zero LAGB patients.
