Abstract
Background
It is unclear whether preoperative biliary drainage (PBD) by endoscopic retrograde cholangiopancreatography (ERCP) is equivalent to electrocautery-enhanced lumen-apposing metal stent (ECE-LAMS) before pancreatoduodenectomy (PD).
Methods
Patients who underwent PBD for distal malignant biliary obstruction (DMBO) followed by PD were retrospectively included in nine expert centers between 2015 and 2022. ERCP or endoscopic ultrasound-guided choledochoduodenostomy with ECE-LAMS were performed. In intent-to-treat analysis, patients drained with ECE-LAMS were considered the study group (first-LAMS group) and those drained with conventional transpapillary stent the control group (first-cannulation group). The rates of technical success, clinical success, drainage-related complications, surgical complications, and oncological outcomes were analyzed.
Results
Among 156 patients, 128 underwent ERCP and 28 ECE-LAMS in first intent. The technical and clinical success rates were 83.5% and 70.2% in the first-cannulation group versus 100% and 89.3% in the first-LAMS group (p = 0.02 and p = 0.05, respectively). The overall complication rate over the entire patient journey was 93.7% in first-cannulation group versus 92.0% in first-LAMS group (p = 0.04). The overall endoscopic complication rate was 30.5% in first-cannulation group versus 17.9% in first-LAMS group (p = 0.25). The overall complication rate after PD was higher in the first-cannulation group than in the first-LAMS group (92.2% versus 75.0%, p = 0.016). Overall survival and progression-free survival did not differ between the groups.
Conclusions
PBD with ECE-LAMS is easier to deploy and more efficient than ERCP in patients with DMBO. It is associated with less surgical complications after pancreatoduodenectomy without compromising the oncological outcome.
