[Annular pancreas]

Area of Science:

• Gastroenterology
• Surgical Gastroenterology
• Radiology

Background:

• Annular pancreas is a rare congenital anomaly where pancreatic tissue encircles the duodenum.
• Diagnosis can be challenging, often requiring a combination of clinical, radiological, and endoscopic evaluation.
• Optimal surgical management remains a topic of discussion, aiming to alleviate duodenal obstruction and associated symptoms.

Observation:

• The study presents 5 clinical cases of annular pancreas.
• Clinico-radiological characteristics were analyzed based on these cases and existing literature.
• Key diagnostic features and patient presentations were documented.

Findings:

• Specific clinico-radiological patterns associated with annular pancreas were identified.
• Recommendations for surgical procedure selection were formulated based on observed characteristics.
• The efficacy of collateral anastomoses, with or without vagotomy, was considered.

Implications:

• Understanding the clinico-radiological features aids in timely diagnosis of annular pancreas.
• The study provides guidance for surgeons in selecting appropriate surgical interventions.
• Consideration of collateral anastomoses may improve outcomes in surgical management of annular pancreas.
