About this study

To study the influence of different types of periampullary diverticulum(PAD) on ERCP difficult cannulation and postoperative complications.

Read the detailed description

Periampullary diverticula (PAD) are extraluminal out-pouching of the duodenum mucosa often occurring within a radius of 2-3 cm from the ampulla of Vater or hepatopancreatic ampulla. More PAD cases have been identified over recent years, and it's generally believed that up to 27% of elderly cases may have PAD. Several classifications of PAD have been proposed, and the most commonly used distinguishes intraluminal and extraluminal diverticula. Recent studies suggest that PAD is a risk factor for the development of bile duct diseases, and it may cause endoscopic retrograde cholangiopancreatography (ERCP) procedures to fail, but some other studies have come to the opposite conclusion.

During ERCP procedures, the investigators found that different types of PAD seem to have some differences in the size of the diverticulum, difficulty in intubation, and complications. The investigators plan to this retrospectively study collecting 4 years of cases to evaluate the clinical features of different types of PAD in terms of difficult cannulation and complications.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Difficulty cannulation

    The inability to achieve selective biliary cannulation by the standard ERCP technique within 10 minutes or 5 attempts or failure of access to the major papilla.

    Measured: 1 month

Secondary outcomes (10)
  1. Diameter of diverticulum

    Maximum diameter of PAD observed during ERCP

    Measured: 1 month

  2. Diameter of common bile duct

    Maximum diameter of common bile duct observed during ERCP

    Measured: 1 month

  3. X-ray exposure time

    The total radiography time during ERCP

    Measured: 1 month

  4. Pancreatic duct insertion times

    Times of any accessories goes into the pancreatic duct, no matter how depth

    Measured: 1 month

  5. Post-ERCP pancreatitis

    Upper abdominal pain with serum amylase elevation more than 3 times after the procedure

    Measured: 1 month

  6. Perforation

    CT scan shows retroperitoneal space fluid or gas

    Measured: 1 month

  7. Acute cholangitis

    Intermittent chills and fever after ERCP

    Measured: 1 month

  8. Operation time

    From successful biliary intubation to end of operation

    Measured: 1 month

  9. Secondary treatment rate

    Some patients require secondary treatment, including management of primary diseases and complications

    Measured: 1 month

  10. Hospital stay

    Length of stay in hospital

    Measured: 1 month
