Case 8-1: Severe constipation
A 23-year-old presented with abdominal pain and constipation. He had a history of stooling every 2 to 4 weeks for most of his life, and he had one episode of constipation requiring rectal disimpaction 1 year prior to this visit.
Contrast-enhanced abdominal CT scan (axial view). WA = massive colonic dilatation from stool
Contrast-enhanced abdominal CT scan (coronal view). WA = massive colonic dilatation from stool
The patient’s abdomen was significantly distended with a firm mass and mild tenderness to palpation. The mass could be indented or pushed slowly away by the examining physician’s hand.
Contrast-enhanced abdominal computed tomography (CT) scan in axial and coronal plane demonstrated massive colonic dilatation from impacted stool. The patient was admitted for further management.
The patient went to the operating room on two separate occasions for manual per-rectal disimpaction. Biopsies were taken and were negative for Hirschsprung disease. The patient was discharged with a bowel regimen for constipation. He returned 1 year later with a very similar presentation, again requiring intraoperative disimpaction.
Stercoral perforation occurs when an intraluminal object, most commonly hardened feces, exerts pressure on the bowel wall, causing a locally inflamed and ischemic bowel wall, leading to rupture from local necrosis. It carries a high morbidity and mortality.
