Duodenum preserving pancreatectomy in chronic pancreatitis: design of a randomized controlled trial comparing two surgical techniques [ISRCTN50638764].
BACKGROUND
Chronic pancreatitis is an inflammatory disease which is characterized by an irreversible conversion of pancreatic parenchyma to fibrous tissue. Beside obstructive jaundice and pseudocyst formation, about half of the patients need surgical intervention due to untreatable chronic pain during the course of the disease. In most of the patients with chronic pancreatitis, the head of the pancreas is the trigger of the chronic inflammatory process. Therefore, resection of pancreatic head tissue must be the central part of any surgical intervention. However, it is unclear to which extent the surgical procedure must be radical in order to obtain a favourable outcome for the patients.


METHODS
A single centre randomized controlled, superiority trial to compare two techniques of duodenum preserving pancreatic head resection.


METHODS
65 patients will be included and randomized intraoperatively.


METHODS
All patients with chronic pancreatitis and indication for surgical resection and signed informed consent. Cumulative primary endpoint (hierarchical model): duration of surgical procedure, quality of life after one year, duration of intensive care unit stay, duration of hospital stay. Reference treatment: Resection of the pancreatic head with dissection of the pancreas from the portal vein and transsection of the gland (Beger procedure).


METHODS
Partial Resection of the pancreatic head without transsection of the organ and visualization of the portal vein (Berne procedure).


METHODS
September 2003-October 2007.
The trial is conducted in compliance with the protocol and in accordance with the moral, ethical, regulatory and scientific principles governing clinical research as set out in the Declaration of Helsinki (1989) and the Good Clinical Practice guideline (GCP). The Center for Clinical Studies of the Department of Surgery Heidelberg is responsible for planning, conducting and final analysis of the trial.
