Article Abstract
The pathogenic mechanisms underlying sphincter of Oddi dysfunction (SOD) remain incompletely understood, and it often leads to severe symptoms encompassing nausea, vomiting, and abdominal pain. New evidence now suggests correlations between nitric oxide (NO) and SOD. In this review, we summarized the factors influencing SOD pathogenesis via NO and its derivative, the peroxynitrite anion. NO appears to enhance SOD progression by modulating sphincter of Oddi (SO) contractions via NO-sGC-cGMP signaling or inducing the apoptosis of enteric neurons, interstitial cells of Cajal, smooth muscle cells, and other cellular components via peroxynitrite anion-mediated organelle damage. Thus, a comprehensive understanding of SOD will provide a foundation for the identification of potential drugs and treatment approaches.

[Protection of sphincter of Oddi function from the viewpoint of confluence diseases of pancreaticobtlary ducts].

The confluence diseases of pancreaticobiliary ducts are important causes of benign and malignant diseases such as inflammation, stones, and tumors of the biliary and pancreatic systems. Endoscopic retrograde cholangiopancreatography (ERCP) has played an important role in the diagnosis and treatment of the confluence diseases of pancreaticobiliary ducts and the biliary and pancreatic systems diseases. However, excessive damage to the sphincter of Oddi (SO) can break the biliary tightness, leading to complications such as reflux cholangitis, stones, and tumors.

Introduction: The weakest part of the duodenal wall is the ampulla of Vater, since here the circular arrangement of the duodenal musculature is destructured to integrate the sphincter of Oddi. This characteristic could be the reason why most duodenal diverticula appear in the juxtapapillary region, even including the papilla inside.
Objective: The objective of the research was to determine the patients diagnosed with juxtapapillary diverticulum (JD) after endoscopic retrograde cholangiopancreatography (ERCP), who were confused with different previous diagnoses.
Medical cannabis for the management of pain in chronic pancreatitis with recurrent exacerbations: a case report.

Introduction: Control of pain in patients affected by chronic pancreatitis with recurrent exacerbations is a challenging condition, with conventional therapies often providing limited relief. This case report describes the use of medical cannabis as a novel approach in a patient with refractory chronic pancreatitis, contributing to the growing interest in alternative treatments for pain and inflammation in similar complex cases.
Case Presentation: A 54-year-old woman with a 24-year history of chronic pancreatitis caused by recurrent acute pancreatitis presented with persistent, severe abdominal pain and recurrent exacerbations despite undergoing numerous conventional interventions, including cholecystectomy, enzyme supplementation, repeated endoscopic retrograde cholangiopancreatographies (ERCPs), and stent placements.
Spinal Cord Stimulation for Diffuse Visceral Hyperalgesia in the Abdomen: A Case Report and Literature Review.

Introduction: Spinal cord stimulation (SCS) for chronic abdominal pain is not novel. However, this has been explored only when the pain has a clear dermatomal association such as the right upper quadrant for sphincter of Oddi dysfunction or the left upper quadrant for post-traumatic splenectomy. The present report thereby discusses the utility of SCS when the visceral pain is diffusely distributed across all four quadrants of the abdomen.
