Goals:
The aim of this study was to determine the risk and identify the factors associated with post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in patients who undergo needle knife precut sphincterotomy (NKS). In addition, we evaluated the effect of gabexate for the prevention of post-ERCP pancreatitis.
Background:
NKS, after repeated cannulation attempts during ERCP, is known to increase the risk of post-ERCP pancreatitis. However, the specific risk factors for post-ERCP pancreatitis have not been identified, and the preventive role of protease inhibitors, such as gabexate, has not yet been established.
Study:
The medical records of 200 patients who underwent NKS, after repeated cannulation attempts during ERCP, were reviewed retrospectively. The potential risk factors for post-ERCP pancreatitis were investigated. The effect of gabexate infused after the ERCP procedure was also evaluated.
Results:
Thirteen (6.5%) patients out of 200 developed post-ERCP pancreatitis. Sex, age, the presence of pancreatitis at procedure, underlying disease, direction of the sphincterotomy, success or failure of cannulation after NKS, diameter of common bile duct, pancreatic duct status, and the presence of acinar filling were not associated with the risk of pancreatitis. Gabexate infusion after ERCP increased the incidence of ERCP-associated pancreatitis.
Conclusions:
We could not identify any risk factors associated with the development of post-ERCP pancreatitis in patients who underwent NKS after repeated cannulation attempts during ERCP. However, gabexate administered after the ERCP procedure was found to increase the incidence of pancreatitis.
