Toxic megacolon is a devastating complication of colitis, which is commonly caused by inflammatory bowel disease. Frequently reported complications of toxic megacolon are bleeding, sepsis, colon perforation, and shock. Herein, we report a rare case of cardiac arrest that was likely caused by toxic megacolon in a 49-year-old male, who experienced 3 months of intermittent dyspnea and abdominal distension that abruptly worsened before presentation. Our case suggests that severe colon dilation complicated by toxic megacolon, especially accompanied by cardiopulmonary symptoms and signs, has the potential to progress to an abdominal compartment syndrome, which is a rare but life-threatening complication.

Cytomegalovirus is a frequent opportunistic pathogen in immunosuppressed patients and CMV colitis is one of its major complications. It usually presents as gastrointestinal ulceration with bleeding or perforation, but it can also take less common forms resembling many other entities, including viral gastroenteritis, ischemic colitis, intestinal pseudo-obstuction, toxic megacolon. We experienced a 49-year-old man with symptom of severe constipation and lower abdominal pain. He was diagnosed as having focal segmental glomerulosclerosis by renal biopsy, but he was an immunocompetent state. An abdominal X-ray showed marked dilatation of descending colon without air-fluid level. At colonoscopy and biopsy, he was diagnosed as having CMV colitis with focal stenosis. Treatment for two weeks with ganciclovir resulted in resolution of colitis, but stenosis was remained. We report a case of toxic megacolon and focal stenosis due to CMV colitis in a FSGS patient. It was not certain whether FSGS was related with immunosuppressive state.

Megacolon is an uncommon condition in which the bowel is persistently of increased diameter and it is always associated with long-standing constipation. Two main groups are recognized according to whether or not ganglia are present in the intermuscular plane of the rectal wall. Their complete absence, even along a short segment of rectum, denotes Hirschspurung's disease. If ganglia are present, the dilated bowel may be secondary to some predisposing factor such as a stricture, a congenital anorectal abnormality, a cauda equina lesion etc. In other instances, however, there may be no apparent organic reason as to why the bowel should be so dilated. This latter condition is termed "idiopathic megacolon". We report the case of one female patient with idiopathic megacolon. During medical treatment, she was complicated with a sigmoid volvulus, we performed subtotal colectomy and cecorectal anastomosis and she improved without any complication.

Many hemodialysis patients, because of low fiber diet, water restriction, phosphate binder and endocrine-metabolic disturbance, suffer from chronic constipation. In a state of chronic constipation, a large amount of hard fecal mass often results in fecal impaction. Megacolon, urinary obstruction and perforation of the large bowel rarely develop as a complication of fecal impaction. The authors experienced a case of idiopathic sigmoid colonic perforation, with fecal impaction, in a 66-year-old woman having undergone hemodialyis of 6 years duration. The clinical features of the case are presented, with a review of the literatures.

Amyloidosis is characterized by extracellular deposition of protein fibrils in one or multiple organs. AA amyloidosis is secondarily occurred to be related with chronic infections or inflammatory diseases. We report a 67-year-old man suffered from secondary AA amyloidosis related with chronic Clostridium difficile colitis after repeated total hip replacement surgery. Infection control is the most important treatment of AA amyloidosis secondary to chronic infection. However, the patient's C. difficile colitis was not controlled well, eventually toxic megacolon with sepsis was developed. Consequently, he had to take total colectomy, but he expired with multi-organ failures. We suggested that early surgical procedure might be one option for intractable C. difficile colitis complicated with secondary amyloidosis.

Colonic pseudo-obstruction, which is characterized by repetitive episodes or continuous symptoms and signs of a bowel obstruction, is a rare disease that results in colorectal dilatation without any obstructing lesions. Cases with neuropathic chronic colonic pseudo-obstruction have rarely been reported in Korea. We report a case of neuropathic colonic pseudo-obstruction, which results in decreased number of interstitial cells of Cajal and hypoganglionosis, in a 50-year-old man with chronic constipation accompanied by megacolon.
