ErCP for Pancreas Divisum: A Shifting Paradigm in Treatment

The standard approach to treating pancreas divisum, a common anatomical variation, might potentially be undergoing a meaningful shift. For years, endoscopic retrograde cholangiopancreatography (ERCP) with minor papilla endoscopic sphincterotomy has been a go-to procedure.However, recent research suggests this intervention may not offer the benefits once believed and could even expose patients to unnecessary risks. The implications of these findings could reshape clinical guidelines and patient care strategies.

Understanding Pancreas Divisum and Current Treatments

Pancreas divisum is an anatomical variation occurring in approximately 7%-10% of the population, where the ducts of the pancreas do not properly fuse during development. This can lead to impaired drainage and an increased risk of recurrent acute pancreatitis. Traditionally, ERCP with minor papilla endoscopic sphincterotomy has been employed to widen the opening of the minor papilla and improve pancreatic drainage.

The rationale behind this treatment stemmed from retrospective studies indicating that many patients who underwent the procedure experienced a reduction in recurrent pancreatitis episodes. But these studies lacked a crucial element: a control group for comparison.

The SHARP Trial: A Game Changer

The multicenter SHARP trial, conducted between September 2018 and August 2024, aimed to address the gap in knowledge by comparing ERCP with minor papilla endoscopic sphincterotomy to a sham procedure. The trial involved 148 patients with pancreas divisum who were randomized into two groups: one receiving ERCP with sphincterotomy (n=75) and the other undergoing a sham treatment (n=73).

the results of the SHARP trial challenged the conventional wisdom. The study found that patients who underwent ERCP with sphincterotomy were no less likely to experience recurrent acute pancreatitis compared to those who received the sham treatment.This finding suggests that the procedure may not provide the intended benefit and could expose patients to unnecessary risks associated with ERCP.

Key Findings of the SHARP Trial

• No significant difference in the rate of recurrent acute pancreatitis between the ERCP and sham groups.
• Subgroup analysis revealed no treatment effect based on factors such as age, diabetes status, sex, alcohol or tobacco use.
• The study highlights the importance of questioning established practices in the absence of rigorous evidence.

Risks Associated with ERCP

ERCP is an invasive procedure that carries inherent risks, including pancreatitis, bleeding, infection, and perforation. Given the lack of demonstrated benefit in the SHARP trial, subjecting patients with pancreas divisum to these risks may be unwarranted.

Implications for Clinical Guidelines and Future Treatment Approaches

The findings from the SHARP trial have significant implications for clinical guidelines and the management of pancreas divisum. According to the study’s author, Gregory A. Coté, MD, current guidelines recommending ERCP as a treatment for pancreas divisum are likely to change.The study suggests that pancreas divisum anatomy should no longer be considered an indication for ERCP, even in cases of idiopathic acute pancreatitis.

so, what are the alternative approaches to managing pancreas divisum? While ERCP may be losing favor, other strategies can help mitigate the risk of recurrent pancreatitis. These include:

• Lifestyle modifications: Avoiding alcohol and tobacco use can reduce the risk of pancreatitis.
• Pain management: Medications can help manage pain associated with acute pancreatitis episodes.
• Hydration: Adequate fluid intake is essential for pancreatic health.
• Further research: Exploring other potential interventions, such as medications or minimally invasive procedures, may offer new avenues for treatment.

The Future of pancreas Divisum treatment

Looking ahead, the management of pancreas divisum is likely to become more conservative, with a greater emphasis on lifestyle modifications and pain management. Future research will focus on identifying patients who may benefit from alternative interventions and developing less invasive techniques to improve pancreatic drainage.

One promising area of research is the use of advanced imaging techniques to better understand the anatomical variations associated with pancreas divisum and identify potential targets for intervention. Additionally, studies are needed to evaluate the long-term outcomes of different treatment strategies and determine the most effective approach for preventing recurrent pancreatitis.

Pancreas Divisum Treatment: Dr. Anya Sharma on the Shifting Paradigm

Archyde News is pleased to present an exclusive interview with Dr. Anya Sharma, a leading gastroenterologist and researcher specializing in pancreatic disorders. Dr. Sharma has been following the developments in pancreas divisum treatment and offers valuable insights into the changing landscape.

Interview with Dr. Anya Sharma

Archyde News: Dr. Sharma, thank you for joining us. Can you start by explaining what pancreas divisum is and why it is clinically meaningful?

Dr. Sharma: Certainly. Pancreas divisum is a relatively common anatomical variation where the main pancreatic duct doesn’t fully fuse during fetal development. This can lead to impaired pancreatic drainage and, consequently, an increased risk of recurrent acute pancreatitis in some patients.

Archyde News: The standard treatment for pancreas divisum has historically been ERCP with minor papilla endoscopic sphincterotomy. What has been the rationale behind this approach?

Dr. Sharma: The rationale was that widening the minor papilla, where the smaller pancreatic duct drains, would improve pancreatic drainage and reduce the frequency of pancreatitis episodes. Before the SHARP trial, the evidence mainly came from observational studies that showed a positive correlation. Though, thay lacked a critical element – a control group.

Archyde News: And that brings us to the SHARP trial. Can you describe the trial and its principal findings?

Dr. Sharma: The SHARP (Sphincterotomy for High-risk Anatomical pancreas divisum) trial was a game-changer. It aimed to compare ERCP with sphincterotomy to a sham procedure in patients with pancreas divisum. The results were quite surprising. The trial demonstrated that ERCP with sphincterotomy offered no significant benefit over the sham procedure in lowering the instances of recurrent acute pancreatitis.

Archyde News: That is certainly a shift from what was previously believed. What are the clinical implications of these findings, specifically for current clinical guidelines?

Dr. Sharma: The implications are potentially vast. The current guidelines that suggest that the pancreas divisum anatomy be considered a direct factor for ERCP are likely to change.We need to reinterpret the clinical management of patients with this anatomical variant. The SHARP study clearly suggests that pancreas divisum,in itself,shouldn’t be a reason for an ERCP.This also shifts our treatment practices dramatically.

Archyde News: What are the inherent risks associated with ERCP that clinicians and patients should be aware of?

Dr. Sharma: ERCP is an invasive procedure, and like any invasive procedure, it carries risks. These risks include the potential for post-ERCP pancreatitis, bleeding, infection, and even perforation of the bowel. Given the lack of proven benefit in the SHARP trial,these risks become even more crucial to consider.

archyde News: So, if ERCP is losing favor, what option approaches are being considered for managing pancreas divisum?

Dr. Sharma: We’re moving toward a more conservative approach. Lifestyle modifications are very important. Patients can minimize alcohol and tobacco use, which reduces the risk of pancreatitis flare-ups. Pain management plays a vital role in helping patients cope during acute episodes, alongside ensuring adequate hydration. Further, more research is needed to explore other alternative interventions, such as new medications and minimally invasive procedures, may also offer avenues for treatment.

Archyde News: What does the future of pancreas divisum treatment look like?

Dr. Sharma: The future likely involves more conservative treatments,with an emphasis on lifestyle adjustments and symptomatic treatment. We hope to identify and categorize the patients who may benefit from alternative interventions. I believe a more thorough investigation of the anatomical variants is also needed. Advanced imaging techniques may help us to better understand these variations and identify potential intervention targets. We need to study the results of new treatments to determine the most effective approach for preventing the recurrent onset of pancreatitis.
