Cattell-Warren Versus Blumgart Techniques of Pancreatico-jejunostomy Following Pancreato-duodenectomy

Phase 3
Completed
Conditions
Pancreatic Cancer
Interventions
Procedure: Blumgart Anastomosis
Procedure: Cattell-Warren Anastomosis
Registration Number
NCT02457156
Lead Sponsor
University of Liverpool
Brief Summary

The purpose of this study is to compare two different techniques of performing a pancreatic anastomosis; Cattell-Warren versus Blumgart to determine if a Blumgart anastomosis reduces pancreatic remnant leak, post-operative complications and overall length of hospital stay.

Detailed Description

This is a randomised controlled, phase III, double blinded, multicentre clinical trial comparing Cattell-Warren (CWA) versus. Blumgart (BA) methods of pancreaticojejunostomy following pancreaticduodenectomy for supected malignancy of the pancreatic head.

The primary objective of the trial is to establish if the Blumgart anastomosis reduces pancreatic remnant leak and in turn complications, hospital stay, cost and promote enhanced recorvery programs.

506 patients (253 patients per treatment arm) will be recruited from approximately 7 centres throughout the United Kingdom.

Patients recommended for resection who provide written informed consent will be randomised to one of the following treatment arms on the day of surgery by the surgeon:

Arm A: Blumgart method of panreaticojejunostomy. Arm B: CattellWarren method pf pancreaticojejunostomy.

Randomisation will be undertaken intra-operatively, following pancreatic head excision, just prior to pancreatic head remnant reconstruction.

Patients will be assessed post operatively on days 3 to 7 and on day of dishcharge from hospital. Patients will continue to be followed up in the outpatient setting at 3, 6 and 12 months post surgery.

All laboratory and physical assessments performed will be in line standard care.

Blood samples for the translational study will be taken subject to informed consent pre-operatively and post-operatively 5 days after surgery.

A histological (H\&E stained) slide of the pancreatic transection margin should be taken as routine. This will be requested from each patient for central pathology review to assess the amount of fibrosis.

Primary Outcome Measures
NameTimeMethod
Presence or absence of post-operative pancreatic fistulaAssessed up to 3 months after surgery.

Post-operative pancreatic fistula are defined as any abnormal connection between the pancreatic duct epithelium and another epithelised surface, which contains pancreatic derived, enzyme rich fluid. This will be assessed up to 3 months following surgery on inpatient days 3-7, day of discharge (expected to be 1 - 5 weeks after surgery) and 3 month follow up.

Secondary Outcome Measures
