1/3. Idiopathic megacolon presenting with fatal inferior vena caval obstruction and colonic perforation. Case report.

    A 73-year-old woman with chronic constipation and associated megarectum and megacolon presented as an emergency with colonic perforation, inferior vena caval obstruction and urinary retention. Soon after admission the patient sustained a massive feculent vomit and died. Intractable constipation demands referral for further investigation, if similarly neglected cases are to be avoided. Idiopathic megacolon presenting in this way has not been previously reported.

2/3. urinary retention due to idiopathic megacolon.

    A 58-year-old man with neurogenic bladder dysfunction was hospitalized with chief complaints of urinary retention and abdominal distention. He had been treated for neurogenic bladder due to cerebral infarction for 3 years. The pelvic CT scan and excretory urogram revealed an obstruction of the neck of the bladder due to an abundant stool, which was found to have resulted from adult idiopathic megacolon. A permanent colostomy with sigmoid resection was established. The postoperative urodynamic examination demonstrated improvement of micturition.

3/3. Megacystis and megacolon in an infant with ehlers-danlos syndrome.

    We report a 14 month old male infant with ehlers-danlos syndrome who became 'anuric' due to an acutely dilated urinary bladder. Although the patient was also found to have megacolon, no diverticulum was seen in his gastrointestinal tract or urinary bladder. In order to decompress the urinary bladder and colonic wall, we put an indwelling urinary catheter in place for 2 months, and carried out daily glycerin enema for 3 months. All urological and gastrointestinal symptoms subsided with this intensive medical treatment. The diagnosis of megacystis and megacolon was made very early in life for this patient. This may indicate that the striking extension of gastrointestinal and bladder wall may lead to the development of diverticula of gastrointestinal and urinary tracts in later life.
