Ischemic colitis as a manifestation of thrombotic microangiopathy following bone marrow transplantation.

Thrombotic microangiopathy (TMA) is a microvascular disorder characterized by platelet aggregation and hemolytic anemia. In the setting of bone marrow transplantation (BMT), ischemic colitis due to TMA is difficult to differentiate from acute graft-versus-host disease. We report a 32-year-old man who presented ischemic colitis due to TMA after unrelated BMT for myelodysplastic syndrome. He suffered from treatment-resistant bloody diarrhea, and died of renal failure and Aspergillus pleuritis on day 253 post-BMT. Autopsy revealed endothelial injuries of arterioles and ischemic changes in the intestines and kidneys. Clinical and pathological characteristics of ischemic colitis due to BMT-associated TMA are described.

Ischemic colitis associated with carcinoma of the colon.

Two cases of ischemic colitis occurring proximal to carcinoma of the colon are described, with special reference to the barium enema and pathological findings. The association of these two conditions is rare but when present may cause some confusion. It is possible that the two lesions may, for instance, be considered to be both due to ischemic colitis, or mistaken for granulomatous colitis with a stricture.

[Results of surgical treatment of ischemic colitis].

Between January 1984 and December 1989, 13 patients, aged 39 to 89 (median 63), underwent surgery for histologically proven ischemic colitis. Most suffered from pre-existing cardiovascular conditions (2 shortly after surgery for aortic aneurysm). One patient developed ischemia after the traumatic avulsion of the ileocolic artery and another after the spontaneous reduction of a strangled inguinal hernia. Diagnosis of ischemic colitis was made prior to operation in 4 instances only. The left colon was affected 5 times and the right colon 8 times (with the terminal coil of ileum 3 times). Treatment always consisted in segmental colectomy; laparotomy was used in 3 patients (2 to 7 reoperations). Colon anastomosis was performed directly 5 times, while 4 patients had secondary stomy closures; 2 patients still have their original stomy. Two patients died (15%), one of sepsis and the other following broncho-aspiration. The prognosis of ischemic colitis is rather favorable, even at the stage of transmural necrosis, provided all ischemic zones are resected. This is in contrast with the severe mortality of mesenteric infarcts, when extensive small bowel necrosis is found in association with colonic ischemia.

Reevaluation of clinical features of ischemic colitis. Analysis of 68 consecutive cases diagnosed by early colonoscopy.

BACKGROUND: Ischemic colitis (IC) is generally considered a disease of elderly patients who have associated diseases. The aim of the present study was to reevaluate the clinical features of IC. METHODS: We retrospectively analyzed the clinical characteristics, background, and endoscopic and histologic changes in 68 consecutive patients (16 men and 52 women) with this disease diagnosed by early colonoscopy. RESULTS: The patients' age ranged from 22 to 98 years (mean, 55 years). Twenty-three patients (34%, including 19 women) were less than 50 years of age. The classical predisposing factors were not discernible in patients younger than 50. Chronic constipation and prior history of abdominal surgery were common in both young and old patients. Early colonoscopy (especially by the 3rd day from onset) showed endoscopic and histologic findings consistent with the characteristics of IC. CONCLUSIONS: IC is not limited only to the elderly, and it should be considered in the differential diagnosis of colitis with melena in younger patients, especially females, who do not have any predisposing factors. Chronic constipation and prior history of abdominal surgery were commonly associated in both young and old patients. Early colonoscopy, especially by the 3rd day from the clinical onset, is essential for the accurate diagnosis of IC.

[Chronic mesenteric ischemia with consecutive ischemic colitis. Suggestions for diagnosis and therapy].

The incidence of acute mesenteric ischaemia has decreased over the last few years. However, cases of chronic mesenteric ischaemia have grown in number, as this disease is the most frequent disorder of the large intestine in the elderly. The typical clinical presentation of ischaemic colitis develops gradually and only becomes recognisable in the late stage of the disease. We present a 51-year-old woman with a history of unexplained abdominal pain. Multislice CT demonstrated an irregular stenosis of the truncus coeliacus and superior mesenteric artery. A Riolan's anastomosis was present and showed excellent perfusion. After a hemicolectomy 6 years previously, different radiologic procedures and endoscopy revealed a structural tumour at the colon transversum we suspected to be malignant. A sequential procedure was conducted. In a first vascular intervention, the truncus coeliacus was reconstructed with a vein patch, and the mesenteric superior artery was replanted. The second laparotomy was performed for revision of the superior mesenteric artery and resection of the intestinal tumour. However, no carcinoma was found in histological examination. In fact, the individual multidisciplinary considerations play an important role in determining the best treatment strategy, if intervention is warranted. Based on our experience, sequential intervention with a common clinical pathway is the safest and most suitable and economic procedure for curing complex pathologies.
