Introduction
The number of bariatric revisional cases has nearly doubled since 2011, and now comprises 13.6% of the total number of cases. The objective of this study is to evaluate the outcomes and safety of the two most common stapling revisional procedures, namely, sleeve and gastric bypass in comparison to primary stapling procedures using the MBSAQIP data registry.
Methods
We reviewed all the sleeve and gastric bypass cases entered between January 1, 2015, and December 31, 2015, in the MBSAQIP data registry. We, then, identified sleeve and bypass patients who have had a previous bariatric procedure. Demographics and 30 day outcomes of all sleeve and gastric bypass patients were analyzed. We conducted within group comparisons comparing primary sleeve gastrectomy (PS) and primary gastric bypass (PB) patients to revisional sleeve (RS) and revisional gastric bypass (RB) patients, respectively. We, then, conducted group comparisons comparing RS to RB patients.
Results
The total number of patients analyzed was 141,577 (98,292 or 69% sleeve patients and 43,285 or 31% gastric bypass patients). Among the sleeve patients, 92,666 (94%) had a PS and 5626 (6%) had RS. Among the bypass patients, 39,567 (91%) had a PB and 3718 patients (9%) had RB. 30-day readmission rate of RS was significantly higher as compared to PS (4.1 vs 0.4%, p < 0.05). The incidence of at least one complication requiring reoperation or reintervention within 30 days following RS was twice as high as compared to PS (1.9 and 2% for RS vs 0.9 and 1.1% for PS respectively, p < 0.05). Length of stay and 30 day mortality rates for PS and RS were the same. 30-day readmission rate of RB as compared to PB was 8.3 vs 6.3% (p < 0.05). Also, the incidence of at least one complication requiring reoperation or reintervention following RB was 3.9 and 4%, respectively vs 2.4 and 2.7% for PB (p < 0.05). In addition, readmission rates and unplanned admission rates to the ICU were significantly higher for RB compared to RS (8.3 and 2% for RB vs 4.1 and 0.9% for RS respectively, p < 0.05). The incidence of at least one reoperation or one intervention following RB were also significantly higher compared to RS (3.9 vs 1.9% and 4 vs 2% respectively, p < 0.05).
Conclusion
Revisional stapling procedures are safe but the rates of complications following RS and RB are twice as high compared to PS and PB. Also, RB are more likely to develop complications compared to RS.
