Summary
A case of acute colonic obstruction, initially thought to be diverticulitis, was found to be caused by sigmoid muscle hypertrophy. This finding highlights a rare cause of bowel obstruction.
Area of Science:
- Gastroenterology
- Colorectal Surgery
Background:
- Acute colonic obstruction is a common surgical emergency.
- Diverticulitis is a frequent cause of colonic obstruction, often requiring surgical intervention.
Observation:
- A patient presented with acute colonic obstruction, initially suspected to be due to acute diverticulitis.
- Emergent surgical intervention was performed based on the initial clinical suspicion.
Findings:
- Pathologic examination revealed no evidence of inflammation, fibrosis, or neoplasia.
- Significant hypertrophy of the sigmoid colon's circular muscle layer was identified as the cause of obstruction.
Implications:
- Sigmoid muscle hypertrophy is a rare but significant cause of acute colonic obstruction.
- This case underscores the importance of thorough histopathological examination in diagnosing colonic obstruction.
- Consideration of muscular hypertrophy is crucial in the differential diagnosis of colonic obstruction, especially when inflammatory or neoplastic causes are excluded.
