The risk of variceal bleeding during endoscopic retrograde cholangiopancreatography.

Abstract

Endoscopic retrograde cholangiopancreatography (ERCP) is a widely performed procedure. However, the risk of variceal bleeding during ERCP has rarely been assessed. This study aims to evaluate the risk of variceal bleeding in patients with esophageal varices (EV) undergoing ERCP. From October 2010 to November 2017, the study retrospectively enrolled 75 cirrhotic patients who received elective ERCP. The patient's risk of gastrointestinal (GI) and variceal bleeding and other procedure-related adverse events within 30 days of ERCP were evaluated. Among the 75 patients, 45 patients (60.0%) had EV. Most of the patients were males (65.3%), and there were high rates of viral hepatitis B-related cirrhosis (36.0%), Child-Pugh B (49.3%), and an indication of choledocholithiasis (40.0%). Thirty-three of 45 (73.3%) patients had high-risk EV, and nine (20.0%) patients had concomitant gastric varices. There was no esophageal variceal bleeding; however, one patient had gastric variceal bleeding after ERCP. Nonvariceal significant GI bleeding occurred in three patients with EV and one without EV ( p = 0.529). Post-ERCP pancreatitis occurred in three patients with EV and five without EV ( p = 0.169). No perforation or procedure-associated mortality was noted. The risk of esophageal variceal bleeding within 30 days of ERCP is neglectable, except for a patient who suffered from gastric variceal bleeding. Other complications, such as nonvariceal bleeding and pancreatitis, are also no higher in patients with EV. Therefore, ERCP is generally a safe procedure for a patient with high-risk esophageal varices.
