Insights
A rare omphalomesenteric duct cyst caused small bowel obstruction in a 69-year-old man with no prior abdominal surgery. This case highlights a rare cause of mechanical small bowel obstruction in older adults.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Medical Case Reports
Background:
- Mechanical small bowel obstruction (MSBO) is frequently caused by prior abdominal surgery.
- Diagnosing and treating MSBO in patients without a surgical history presents significant challenges.
- Omphalomesenteric duct (OMD) remnants are uncommon causes of obstruction, primarily seen in pediatric patients.
Observation:
- A 69-year-old male presented with symptoms of small bowel obstruction.
- The patient had no history of abdominal surgery.
- Imaging and subsequent surgical findings revealed an omphalomesenteric duct cyst as the cause of obstruction.
Findings:
- An omphalomesenteric duct cyst was identified as the cause of mechanical small bowel obstruction.
- This presentation is exceptionally rare in individuals over 60 years of age.
- The case underscores the importance of considering rare congenital anomalies in the differential diagnosis of MSBO.
Implications:
- This case expands the known spectrum of omphalomesenteric duct remnant presentations.
- It emphasizes the need for thorough diagnostic evaluation in elderly patients with MSBO and no surgical history.
- Highlights the potential for rare congenital anomalies to cause significant pathology in adulthood.
Abstract:
Previous abdominal surgery is the most common cause of mechanical small bowel obstruction. However, in patients with no history of abdominal surgery, the diagnosis and treatment of mechanical small bowel obstruction is difficult. A persistent omphalomesenteric duct remnant is a rare finding that typically presents in the pediatric population and is extremely rare in patients aged > 60 years. In the present report, we describe the case of an omphalomesenteric duct cyst causing small bowel obstruction in a 69-year-old man with no history of a surgical procedure.

Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
