Effects of Pancreaticoduodenectomy on Glucose Metabolism

January 24, 2016 updated by: National Taiwan University Hospital
Pancreaticoduodenectomy (PD) involves removing the head of pancreas, duodenum, common bile duct, gall bladder, and/or distal stomach. In general, the postoperative changes are thought to be moderately severe, and about 20% of these patients go on to develop new clinical diabetes. PD-related factors of glucose metabolism will include removal of half of the pancreatic endocrine tissue, exclusion of the proximal small intestine, postoperative weight loss (on average, ~8% of body weight), and removal of putative diabetogenic factor in resected neoplasm. However, effect of removal of duodenum on glucose metabolism after PD has never been studied. The investigators plan to examine this issue by comparing fasting plasma levels of insulin, fasting plasma glucose, C-peptide, HbA1C, HOMA-insulin resistance, GLP-1 response after a standard meal, and body mass index (BMI) of patients before and after PD.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Questionaire All studied patients will be requested to self-complete a detailed questionnaire that collects information on demographic data, including usual adult height and weight, and history of DM in first-degree relatives. Existing medical conditions, including DM, duration of these medical problems, and current medications will also be inquired. The database will also include details of weight measured at the time of recruitment and body mass index (BMI), calculated as weight (kg)/height2 (m2). All studied patients will have FBG levels measured. Patients receiving prescription antidiabetic medications for previously diagnosed DM will be classified as having DM regardless of their FBG value. Among patients not reporting treatment for DM, classification of DM status will be based on the American Diabetes Association criteria; patients will be classified as having DM if the FBG level is ≧126 mg/dL (7 mmol/L), as having impaired fasting glucose (IFG) if their FBG is between 100 and 125 mg/dL (5.6-6.9 mmol/L), and as having normal fasting glucose (NFG) if their FBG value is ≦99 mg/dL (5.5 mmol/L).

After withdrawal of anti-diabetic medications for 12 h, the patients were asked to fast overnight for 12 h, then were given 200 ml of formula (220kcal, 14g of protein, 28 g of carbohydrates, and 5 g of fat; Modifast, Stocksund, Sweden) within 10 min through a NG tube on post-operative day 5 (proximal feeding group [PFG]) and a jejunostomy feeding tube (distal feeding group [DFG]) on post-operative day 6. The below parameter will be checked, including

  1. HOMA insulin resistance assessment (HOMA-IR)
  2. GLP-1
  3. GIP
  4. C-peptide
  5. Insulin
  6. Glucose

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
