Single-centre Propensity Score-matched Comparison of Laparoscopic Versus Open Pancreatoduodenectomy

Morbidity and Survival After Minimally Invasive Versus Open Pancreatoduodenectomy: Propensity Score Matched Comparison

Minimally invasive pancreatoduodenectomy is increasingly performed. However, technical challenges and a perceived higher risk of complications has hindered wide adoption of a minimally invasive approach.

This is a retrospective comparison of a prospectively kept database. The investigators compared surgical outcomes and survival after laparoscopic (LPD) versus open pancreatoduodenectomy (OPD). In order to reduce the effect of bias and confounding, baseline characteristics of both groups were matched using propensity score matching.

All pancreatoduodenectomies were retrieved from a prospectively kept database and retrospectively analysed. All procedures were performed in a single supra-regional Belgian centre.

The primary endpoint was the major complication rate, defined by a Clavien-Dindo morbidity classification grade IIIa or higher [11]. Secondary endpoints were 90-day mortality rate, length of hospital stay, operative time, blood loss, transfusion requirements and specific pancreatic complications (pancreatic fistula, haemorrhage, and delayed gastric emptying). In addition, overall survival (OS) and disease-free survival (DFS) were analysed in the subgroups of cancer patients.
