Abstract

Introduction: In adults, mechanical small intestinal obstruction (MSBO) is a frequent emergency condition that
usually necessitates immediate surgery and hospitalization. Most occurrences are caused by common conditions
including adhesion bands, and abdominal wall hernias. However, the surgeons may encounter unanticipated
problems due to uncommon origins of this condition. Untreated MSBO raises the chance of bowel segment
perforation and strangulation, regardless of the underlying reason.
Aim of work: To present unusual causes of acute small bowel obstruction that pose a diagnostic difficulty.
Patients and methods: We presented nine cases who presented with mechanical small intestinal obstruction
due to unusual causes. This study looks closely at the challenges that emergency general surgeons encounter
when treating patients with rare causes of mechanical small intestinal obstruction.
Conclusion: Emergency surgeons should be knowledgeable of the uncommon or unusual causes of mechanical
small intestine obstruction in adults before serious complications arise. Successful outcomes need rapid surgical
intervention, clinical suspicion, utilization of suitable radiological investigations and knowledge of the normal
anatomy and its deviations.
