Benchmarking Outcomes in Pancreatoduodenectomy With Portal Vein Resection - WhippleBenchmarks.Org

The WhippleBenchmark 2 Collaborative study aims at defining benchmark criteria for best achievable outcomes after pancreaticoduodenectomy with portal vein resection.

Study Overview

• Status: Completed
• Conditions: Pancreatic Neoplasms; Pancreaticoduodenectomy
• Intervention / Treatment: Procedure: Pancreaticoduodenectomy with portal vein resection

Detailed Description

Pancreatoduodenectomy (PD) with portal vein resection (PVR) is performed for the achievement of complete resection (R0) in patients with locally advanced pancreatic head lesions. Despite most commonly performed in high-volume pancreatic surgery centers by experienced surgeons, best achievable outcomes, such as morbidity and mortality, following such complex procedure remain unknown.

The aim is to conduct a retrospective multicenter cohort study to define benchmark values for best achievable outcomes following duodenopancreatectomy (DP) with portal vein resection (PVR).

Data collection and study design are based on to the well established standardized reporting for benchmarking (Sánchez-Velázquez et. al. Ann Surg, February 2019 ).

This multicenter cohort study will include all consecutive pancreaticoduodenectomies with portal vein resections from at least 20 high volume centers performing over 50 pancreatic operations per year or 150 cases within 3 years from at least 3 continents over a period of 10 years (2009-2019). Every center included in the study must have a prospective database from which data can be collected as well as previous publications critically reporting on their outcome.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pancreatic fistula rates	reported according to both the International Study Group of Pancreatic Fistula (ISGPF) and Clavien-Dindo classification.	12 months
Hospital readmission rate	Any hospital readmission to the primary or other peripheral hospitals	12 months
