Summary
Two patients with intermittent intestinal obstruction were diagnosed with primary hypertrophic colonopathy, a condition potentially linked to visceral myopathy. Both individuals remain asymptomatic after surgical intervention.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Pathology
Background:
- Intermittent intestinal obstruction can stem from various colorectal pathologies.
- Primary visceral myopathies are rare neuromuscular disorders affecting the gastrointestinal tract.
Observation:
- Two patients, a 45-year-old man and a 60-year-old woman, presented with symptoms of intermittent intestinal obstruction.
- Barium enema revealed significant narrowing in the man's pelvic-rectal junction and the woman's pelvic colon to anal verge.
- Histological examination of resected tissue showed marked muscularis propria hypertrophy with normal surrounding layers and myenteric plexus.
Findings:
- The histological findings suggest a primary hypertrophic colonopathy.
- This condition is characterized by muscularis propria thickening without mucosal or submucosal abnormalities.
- The myenteric plexus appeared normal, differentiating it from other neuromuscular disorders.
Implications:
- Primary hypertrophic colonopathy may represent a distinct clinical entity or a variant of primary visceral myopathy.
- Successful surgical resection led to asymptomatic outcomes in both reported cases.
- Further research is warranted to understand the pathophysiology and long-term prognosis of this condition.
