Background: Pancreas divisum (PD) is a common anatomical variant of the pancreatic duct system. Only a little percentage of patients with this altered anatomy develop symptoms: acute recurrent pancreatitis (ARP), chronic pancreatitis (CP) and pancreatic-type pain alone. These have been supposed to arise from an obstruction to outflow of the pancreatic dorsal duct due to a stenosis of the minor papilla. Endoscopic sphincterotomy of the minor papilla (MiES) can be considered an effective treatment for patients with PD and ARP supported by stenosis or obstruction of the minor papilla. On the other hand, the access through the minor papilla is essential for therapeutic pancreatic endoscopy in patients with PD and CP, but the effectiveness of MiES in these patients is extremely controversial.
Materials And Methods: Aim of this brief review has been to evaluate the short and long-term effects of endoscopic pancreatic interventions in patients affected by symptomatic PD who underwent therapeutic endoscopic retrograde cholangiopancreatography (ERCP) with pancreatic sphincterotomy of the minor papilla (MiES). The main literature database was Medline (1966-2013).
Results: Data come from a personal overview of articles emerging from the same search strategy.
Conclusions: Nowadays, when endoscopic pancreatic drainage is indicated in patient with symptomatic PD, access through the minor papilla (MiP) is required. Therapeutic endoscopic interventions provide less invasive alternatives to the surgical approach.

Introduction: Gastrointestinal stromal tumors (GIST), which occur anywhere in the gastrointestinal (GI) tract, typically occur in the stomach and small intestine but rarely in the duodenum. We present a case report wherein a descending duodenal GIST was treated with a limited, minimally invasive surgery after endoscopic nasobiliary drainage (ENBD) insertion.

Case Summary: A 7-year-old castrated male domestic shorthair cat was presented for surgical intervention for obstructive pancreatolithiasis. The patient had a history of chronic weight loss, vomiting and lethargy. Elevation of feline pancreas-specific lipase and a marked decrease in cobalamin were documented on blood biochemistry.

Article Synopsis
- - The study aimed to evaluate the detection frequency and anatomy of the duodenal papillae and related structures in cats, using ultrasound on 50 cats.
- - The major duodenal papilla was detected in all cases, while the minor one appeared in 10%. Key dimensions of the anatomical structures were measured in clinically healthy cats.
- - Findings suggest that ultrasound exams of duodenal papillae are straightforward and can be an essential part of diagnosing conditions in feline patients.

Background: Pancreas divisum is an anatomical abnormality where the junction of the main and accessory pancreatic duct fails to occur and the smaller-caliber duct acts as dominant, resulting in overload during the drainage of the organ's secretion through the minor duodenal papilla.
Aims: To report a case of recurrent acute pancreatitis due to symptomatic pancreas divisum who underwent pancreatoduodenectomy.
Case Report: A 21-year-old male patient presented with intermittent painful crises, located in the upper abdomen, with radiation to the back, associated with nausea and vomiting, for the past three years.
Partial agenesis of the dorsal pancreas with features of chronic pancreatitis: A case report.
Radiol Case Rep

Wyagal Radiology Center, Kabul, Afghanistan.
Article Synopsis
- Complete agenesis of the pancreas is life-threatening, but partial agenesis of the dorsal pancreas is less severe and linked to abnormal development; its causes are still unclear.
- A 60-year-old woman's abdominal CT revealed partial agenesis of the dorsal pancreas alongside signs of chronic pancreatitis, with no other complications noted.
- Advances in imaging techniques have increased awareness and diagnosis of partial dorsal pancreas agenesis, and while treatment isn’t required alone, annual check-ups are advised due to potential cancer risk in the ventral pancreas.
