Periampullary diverticula: consequences of failed ERCP

Summary

Periampullary diverticula (PAD) significantly hinder endoscopic retrograde cholangiopancreatography (ERCP) success, particularly in older adults. Intradiverticular papillae pose greater challenges than juxtapapillary diverticula for cannulation.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Biliary Tract Disease

Background:

  • Periampullary diverticula (PAD) are linked to biliary conditions and can complicate endoscopic retrograde cholangiopancreatography (ERCP).
  • ERCP failure rates are notably higher in elderly patients with PAD.

Purpose of the Study:

  • To investigate the prevalence of PAD in patients undergoing ERCP.
  • To determine the impact of PAD on ERCP success rates, focusing on cannulation difficulties.
  • To compare outcomes between intradiverticular and juxtapapillary diverticula.

Main Methods:

  • Retrospective review of 100 consecutive patients with PAD and analysis of 1211 total ERCP cases.
  • Assessment of ampullary cannulation success rates in patients with and without PAD.

  • Comparison of success rates based on diverticula type (intradiverticular vs. juxtapapillary).

    • Main Results:

    • PAD prevalence was 9%, significantly higher in patients aged 75+ (19.2%) versus <75 (4.8%).
    • ERCP cannulation success was 62.4% with PAD versus 92.7% without PAD (P < 0.0001).
    • Success rates were substantially lower for intradiverticular papillae (38.1%) compared to juxtapapillary diverticula (77.6%).

    Conclusions:

    • PAD is a significant factor contributing to ERCP failure, especially in the elderly.
    • Intradiverticular papillae present a greater challenge for successful ampullary cannulation than juxtapapillary diverticula.
    • While many patients with PAD remain asymptomatic, predicting this subset is difficult; surgery is a safe alternative when ERCP fails.
