INTRODUCTION: For patients with super obesity (BMI > 50 kg/m2), biliopancreatic diversion/duodenal switch (BPD/DS) can be an effective bariatric operation. Technical challenges and patient safety concerns, however, have limited its use as a primary procedure. This study sought to assess the safety of primary versus revisional BPD/DS.
MATERIALS AND METHODS: The MBSAQIP database was queried for primary and revisional BPD/DS (2015-2018). Inclusion criteria were patients ≥ 18 years of age, BMI > 50 kg/m2, and with no concurrent procedures. Preoperative variables were compared using a chi-square test or Wilcoxon two-sample tests. Multivariate logistic or robust linear regression models were used to compare outcomes.
RESULTS: There were 3,378 primary BPD/DS and 487 revisional BPD/DS patients. Primary BPD/DS patients had higher BMI (56.5 [IQR4.4] versus 54.8 [IQR4] kg/m2, p < 0.0001) and had more diabetes mellitus type II (29.1% versus 17.2%, p < 0.0001). Intraoperatively, revisional BPD/DS had longer operative time (165 [IQR47] min versus 139 [IQR100] min, p < 0.0001). After adjusting for preoperative characteristics, there was no difference in 30-day readmission or ED visits (primary 12.9% versus revisional 14.6%), reoperation or reintervention (primary 5.7% versus revisional 7.8%), or mortality (primary 0.4% versus revisional 0.6%). In contrast, the revisional BPD/DS patients had higher odds of major morbidity (primary 3.4% versus revisional 5.3%, OR 1.9, CI 1.1-3.2, p = 0.019).
CONCLUSIONS: Revisional BPD/DS is associated with higher morbidity than primary BPD/DS in patients with super obesity. These patients should thus be counselled appropriately when choosing a primary or revisional bariatric procedure.
