Long-Term Outcomes of Endoscopic Intervention in the Treatment of Symptomatic Pancreas Divisum

Efficacy of Endoscopic Therapy in Symptomatic Pancreatic Divisum: A Systematic Review and Meta-analysis

BACKGROUND AND AIMS

Pancreas divisum (PD) is a congenital malformation of the pancreas and is implicated as a cause of pancreatitis. The role of endotherapy has been variable in symptomatic PD indicated by recurrent acute pancreatitis (RAP), chronic pancreatitis (CP), or chronic pancreatic-type abdominal pain (PP). The aim of this study was to analyze the pooled data to determine the success of endoscopic intervention for pancreas divisum.

METHODS

We conducted a comprehensive search of several databases (inception to July 2023) to identify studies reporting on the use of endoscopic therapy in symptomatic pancreatic divisum. The random-effects model was used to calculate the pooled rates and I2% values were used to assess the heterogeneity.

RESULTS

A total of 27 studies were retrieved that reported endoscopic intervention in pancreatic divisum. The calculated pooled rate of technical success was 92% (95% CI: 87-95; I2=63%). The calculated pooled rate of clinical success was 65% (95% CI: 60-70; I2=60%). The rate of clinical success by PD subtypes was highest in RAP at 71% (95% CI: 65-76; I2=24%). Available studies had significant heterogeneity in defining clinical success. The rate of adverse events was 71% (95% CI: 65-76; I2=24%).

CONCLUSIONS

The role of endoscopic therapy in pancreatic divisum is variable with the highest success rate in recurrent acute pancreatitis. Endoscopic intervention is associated with a higher-than-usual rate of adverse events, including post-ERCP pancreatitis.
