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.
