PANasta: Cattell-Warren Versus Blumgart Techniques of Pancreatico-jejunostomy Following Pancreato-duodenectomy
Study Details
Study Description
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.

Outcome Measures
Primary Outcome Measures
- Presence or absence of post-operative pancreatic fistula [Assessed 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
- Entry into programs of adjuvent therapy [3, 6 and 12 month follow up]
- Mortality Rate [Death due to any cause during the study will be recorded]
- Rate of delayed gastric emptying [Post operative day 3, 5, 7, and the day of discharge, which is expected to be between 1 - 5 weeks after surgery.]
- Rate of wound infections [Post operative day 3, 5, 7, the day of discharge, which is expected to be between 1 - 5 weeks after surgery and 3, 6 and 12 month follow up]
- Rate of pulmonary infection [The day of discharge, which is expected to be between 1 - 5 weeks after surgery and 3 month follow up.]
- Rate of post-operative fluid collections [post operative days 3-7, the day of discharge, which is expected to be between 1 - 5 weeks after surgery and 3 month follow-up]
- Operation time [Day of surgery]
- Rate of intra and post-operative bleeding [day of surgery, post operaive day 3, 5, 7 and the day of discharge, which is expected to be between 1 - 5 weeks after surgery]
- Rate of re-operation [Up to 12 months after surgery]
- Rate of venous thrombo-embolism [Post operative day 3, 5, 7, the day of discharge, which is expected to be between 1 - 5 weeks after surgery, 3, 6 and 12 month follow up]
- Length of hospital stay [The day of discharge, which is expected to be between 1 - 5 weeks after surgery, 3, 6 and 12 month follow-up]
- Quality of Life measured by the QLQ-C30 questionnaire [Enrolment, the day of discharge, which is expected to be between 1 - 5 weeks after surgery, 3, 6 and 12 month follow-up]
- Health economic evaluation measured by the EQ-5D questionnaire [Enrolment, the day of discharge, which is expected to be between 1 - 5 weeks after surgery, 3, 6 and 12 month follow-up]
