Abstract
BACKGROUND
Gastrogastric fistula (GGF) is a rare complication from Roux-en-Y gastric bypass (RYGB). It is a known risk factor associated with weight recidivism and an indication for Bariatric Revisional Surgery (BRS).
OBJECTIVES
The primary outcome of this study is to evaluate perioperative outcomes and the long-term total body weight loss (TBWL) outcomes following revision.
SETTING
Single Academic Institution, Center of Bariatric Excellence.
METHODS
We selected patients who had primary bariatric surgery and BRS from 2003 to 2020, followed by BRS for GGF. Patients' demographics, perioperative outcomes, and TBWL were analyzed.
RESULTS
One hundred five patients underwent BRS for GGF. Mean body mass index (BMI) at index operation and revision was 51.6 ± 10.1, and 42.4 ± 11.2 respectively. Ninety percent of patients had open primary RYGB, and 69% had open revisional surgery. The median length of stay after BRS was 3 days. The 30-day reintervention rate was 19%. The 30-day readmission rate was 34%. Of the 77 patients included for weight loss analysis, the mean %TBWL after primary RYGB was 34% ± 14. The total mean %TBWL at the time of revision was 18.8%, translating into a weight regain of 13.6% ± 9.5. The total mean %TBWL after revision was 37.6% ± 11.4, translating into TBWL of 18.8% ± 9.4 after revision when compared to TBWL at revision time.
CONCLUSIONS
Our results demonstrate that revision for GGF can be safely performed, however is associated with higher morbidity than primary bariatric surgery. Revision for GGF results in significant long-term weight loss.
