Abstract
- Acute colonic pseudo-obstruction (ACPO) or Ogilvie's syndrome is a rare disorder of intestinal motility characterized by massive colonic dilatation without mechanical obstruction. We report a case of ACPO combined with rhabdomyolysis induced by severe hypokalemia. A 78-year-old male with a 10-year history of hypertension presented with abdominal pain and distension for 2 days. The laboratory findings showed hypokalemia with markedly elevated serum creatine phosphokinase and myoglobin levels. A plain abdominal x-ray revealed a markedly distended ascending and transverse colon with a cut-off sign at the descending colon. Mechanical obstruction of the intestine was excluded by computed tomography and colonoscopy. He was initially treated with supportive therapy, including insertion of a rectal tube and intravenous fluids with potassium replacement. However, the ACPO persisted, and neostigmine was administered in two separate 2.0-mg intravenous injections, 24 hours apart. Subsequently, the abdominal pain and colonic distension were relieved.
