A Congenital Sac Containing Ileum.

Area of Science:

• Gastroenterology
• Surgical Pathology
• Human Anatomy

Background:

• Intestinal obstruction is a common surgical emergency.
• Meckel's diverticulum is a congenital anomaly with various presentations.
• Peritoneal sacs and vitelline artery remnants can predispose to internal hernias and obstructions.

Purpose of the Study:

• To report a unique case of intestinal obstruction.
• To describe the anatomical abnormalities contributing to the obstruction.
• To highlight a rare complication associated with Meckel's diverticulum.

Main Methods:

• Case report detailing clinical presentation and surgical findings.
• Review of relevant anatomical structures: ileum, Meckel's diverticulum, peritoneal sac, and vitelline artery remnant.
• Pathological examination of the resected specimen.

Main Results:

• A food bolus caused obstruction in a loop of ileum.
• The ileal loop was incarcerated within a peritoneal sac.
• A congenital band, representing an obliterated vitelline artery, connected the Meckel's diverticulum to the caecum, causing internal strangulation.

Conclusions:

• This case illustrates a rare etiology of intestinal obstruction due to a combination of congenital anomalies.
• Meckel's diverticulum and associated vitelline artery remnants can lead to complex internal hernias.
• Awareness of such anatomical variations is crucial for surgical diagnosis and management of intestinal obstruction.
