Pancreas Divisum: Know The Causes and Treatments Options 

Pancreas divisum is a congenital anatomical anomaly that affects approximately 5-10% of the global population. Despite its prevalence, many individuals remain asymptomatic throughout their lives, never realizing they have this condition. However, for some, pancreas divisum can be a source of significant health challenges. 

What is Pancreas Divisum?

Pancreas divisum occurs when the dorsal and ventral pancreatic ducts fail to fuse during embryonic development. In a typical pancreas, these ducts unite to form a single main duct that allows digestive enzymes to flow into the duodenum. However, in pancreas divisum, two separate ducts remain, which can potentially lead to complications such as pancreatitis.

Types of Pancreas Divisum

There are primarily three types of pancreas divisum:

Causes of Pancreas Divisum

The exact cause of pancreas divisum remains a mystery, primarily because it is a congenital condition. During fetal development, the pancreas forms from the fusion of two separate ductal systems. Failure of these ducts to fuse results in pancreas divisum. This anomaly is not inherited, meaning it does not run in families, and there are no known environmental factors that contribute to its occurrence.

Symptoms of Pancreas Divisum

While many individuals with pancreas divisum do not experience symptoms, others may develop notable clinical manifestations. The symptoms can include:

These symptoms are often attributed to the inability of pancreatic juices to flow efficiently through the minor papilla, leading to increased ductal pressure.

Diagnosing Pancreas Divisum

The diagnosis of pancreas divisum can be challenging due to the asymptomatic nature of many cases. However, in symptomatic individuals, the following diagnostic modalities may be employed:

Magnetic Resonance Cholangiopancreatography (MRCP)

MRCP is a non-invasive imaging technique that allows detailed visualization of the pancreatic ductal anatomy. It is often the preferred initial diagnostic tool for identifying pancreas divisum.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

ERCP is a more invasive procedure that can be used both diagnostically and therapeutically. During ERCP, a contrast dye is injected into the pancreatic ducts, and X-rays are taken to reveal any anatomical anomalies.

Secretin-Stimulated MRCP

This advanced form of MRCP provides enhanced images of the pancreatic ducts following the administration of secretin, a hormone that stimulates pancreatic secretion.

Treatment Options for Pancreas Divisum

Treatment for pancreas divisum is primarily focused on managing symptoms and preventing complications such as pancreatitis. Here are some commonly employed treatment strategies:

Endoscopic Therapy

Endoscopic therapy involves the insertion of a stent or performing a sphincterotomy to facilitate drainage through the minor papilla. This method can alleviate symptoms by reducing ductal pressure.

Surgical Intervention

In cases where endoscopic treatments fail, surgical options such as pancreatic duct drainage surgery may be considered to create a new drainage pathway for pancreatic juices.

Medical Management

Medications, including pain relievers and enzyme supplements, can help manage symptoms associated with pancreas divisum, particularly when digestive issues are present.

Prevention and Lifestyle Modifications

Although pancreas divisum cannot be prevented, individuals diagnosed with this condition can adopt certain lifestyle modifications to mitigate symptoms and reduce the risk of complications:
