Here, we review a case of toxic megacolon secondary to C. difficile colitis and review the current literature on diagnosis and management. We identify both clinical and radiologic criteria for diagnosis and discuss both medical and surgical options for management. Ultimately, we recommend using the Jalen criteria in conjunction with daily abdominal radiographs to help establish the diagnosis of toxic megacolon and to make appropriate treatment recommendations. Aggressive medical management using supportive measures and antibiotics should remain the mainstay of treatment. Surgical intervention should be considered if the patient does not clinically improve within 2-3 d of initial treatment.展开更多

Prevailing therapy includes a resection of the affected part of the bowel, However, patients often do not obtain complete functional improvement after surgical treatment. We present the case of a 25-year-old woman who had surgical treatment of lid in early childhood. After that procedure she had clinical features of constipation for years in the end, passing of stool once a week, requiring laxatives and enemas. We diagnosed an incomplete resection of the aganglionic bowel via rectal biopsy and resected the remaining aganglionic segment. Two months after surgery the patient＇s bowel function improved to a frequency of 1-4 stools per day. We conclude that regular follow-up is required to identify lid patients with persistent alterations of bowel function after surgery. In patients presenting with constipation, recognition of a remaining aganglionic segment or other alterations of the enteric nervous system should be aimed at in an early stage. 2005 The WJG Press and Elsevier Inc.

The patient was referred to our institute for abdominal pain and distension. Abdominal X-ray showed marked dilatation of ileum and whole colon without air-fluid level, and sigmoidoscopy with biopsy failed to reveal any specific finding. After 7 d of conservative treatment, massive hematochezia developed, and he was diagnosed to have CMV enterocolitis by colonoscopy with biopsy. Although the diagnosis of CMV enterocolitis was delayed, the patient was treated successfully by repeat colonoscopic decompression and antiviral therapy with intravenous ganciclovir.CONCLUSION This report cautions that CMV-induced colitis should be considered as a possible differential diagnosis in a patient with intractable symptoms of enterocolitis or megacolon of unknown cause, even when the patient is nonimmunocompromised.展开更多

We report a rare case of a 29-year-old male patient with impressive megacolon, in whom Hirschsprung's or Chagas disease was ruled out. In the present case, dilatation of the colon was most likely due to a behavioral disorder with habitual failure of defecation. Chronic stool retention led to a bizarre bulging of the large bowel with displacement of the other abdominal organs and severe occult blood loss. Because of two episodes of life-threatening gastrointestinal bleeding despite conventional treatment of constipation, a surgical approach for bowel restoration was necessary. Temporary loop ileostomy had to be performed for depressurization of the large bowel and the subsequent possibility for effective antegrade colonic lavage to remove impacted stools. Shortly after the operation, the patient was healthy and could easily manage the handling of the ileostomy. However, the course of the megacolon in this young adult cannot be predicted and the follow-up will have to reveal if regression of this extreme colonic distension with reestablishment of regular rectal perception will occur.展开更多

We report a rare case of giant fecaloma in a 22 years old female, with a history of constipation since childhood and an abdominal mass. Abdomen CT scan revealed a giant fecaloma filling sigmoid lumen without signs of ischemia or either complications. Laparotomy and fecaloma extraction trough colotomy was undertaken after failure of conservative measures and endoscopic removal attempt. Hirschsprung disease having been ruled out, sigmoidectomy was performed for idiopathic megacolon. Post operative course was uneventful with good functional outcomes.展开更多
