Evaluation of A New Digestive Reconstruction Procedure Following Pancreatoduodenectomy

August 26, 2013 updated by: Huai-zhi Wang, Southwest Hospital, China

Evaluation of a Modified Procedure of Digestive Tract Reconstruction Following Pancreatoduodenectomy: A Multicenter Randomized Controlled Study

The purpose of this study is to evaluate the validity and safety of a modified operative procedure of digestive tract reconstruction following pancreatoduodenectomy which enables the pancreatic juice and bile to bypass at the pancreatointestinal anastomosis and merge at gastrointestinal anastomosis. It is anticipated that this procedure can decrease the risk of post-surgical pancreatic leakage and preserve the patients' digestive function as well.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Pancreatoduodenectomy (PD) is one of the most complicated surgeries in abdominal clinical practice. It is widely used in the treatment of pancreatic head carcinoma, periampullary carcinoma, chronic pancreatitis with intractable pain, pancreatic head mass which unable to rule out pancreatic cancer. PD was improved in many ways in the last 80 years and the post-surgical mortality has decreased under 5%. Since the resected region of PD is wide including gall bladder, billiary tract, duodenum, pancreas, stomach, jejunum and regional lymph nodes. It has a high prevalence of complications, of which pancreatic leakage is the most common and serious one with a prevalence rate of 5-25% and mortality rate 20-50%。 The objective of the present study is to evaluate a new surgical procedure used for the digestive tract reconstruction following PD. The new procedure enables the pancreatic juice and bile to bypass at the pancreatointestinal anastomosis and merge at gastrointestinal anastomosis which can decrease the risk of post-surgical pancreatic leakage and keep the digestive function of patients. A multicenter, randomized, controlled study is designed to observe the prevalence of pancreatic leakage, other post-surgical complications, hospital stay, medical costs, life quality and other indexes to evaluate the efficacy and safety of this procedure. It is anticipated that through the study, this new procedure can be systematically verified if it is an ideal procedure of digestive reconstruction following PD which can be promoted into wider use.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: up to 12 months
up to 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
