1/110. Subacute ischaemic proctitis: a rare condition requiring extensive rectal surgery.

    Subacute ischaemic proctitis is a rare condition. We describe the case of a 60-year-old male patient who developed, after aortic aneurysm repair, a transient ischaemic colitis that totally healed without sequelae. He eventually developed symptoms of severe proctitis. Investigations identified a stenosis of the mid rectum, while the upper rectum was inflammatory. On angiogram, there was a poor blood flow through the Riolan's arcade and a stenosis of the proximal aorto-graft anastomosis. diagnosis of subacute ischaemic proctitis due to poor blood supply through the internal iliac arteries was made. Anti-inflammatory drugs and dilations were inefficient. A subtotal proctectomy with low colorectal anastomosis was required. On pathological specimen, the lesions were strongly suggestive of an ischaemic process. The patient had an excellent recovery and was asymptomatic 8 months after the operation.

2/110. Refractory proctosigmoiditis caused by myointimal hyperplasia of mesenteric veins: report of a case.

    PURPOSE: Proctosigmoiditis occurring in young adults is usually idiopathic and usually responds to medical management. If the process progresses to pancolitis and is refractory to medical management, proctocolectomy may be required. Myointimal hyperplasia of mesenteric veins, though rare, may also cause proctosigmoiditis, but this entity, in contrast to the idiopathic variety, does not respond to medical management; surgical excision limited to the involved colonic segment is curative. Because the treatment of the two entities differs significantly, it is important to distinguish them diagnostically. The purpose of this case report is to increase awareness of myointimal hyperplasia of mesenteric veins and to emphasize the clinical features that distinguish it from idiopathic proctosigmoiditis. methods: We report the case of a twenty-two-year-old male with an inflammatory process involving the distal colon and rectum, initially thought to be idiopathic proctosigmoiditis. The inflammation did not respond to an extensive course of medical management, and the patient developed complications associated with both the disease process and his medical therapy. Surgical resection of the rectosigmoid was performed. RESULTS: Histologic examination of the resected colon revealed the underlying process to be colonic ischemia caused by myointimal hyperplasia of mesenteric veins not associated with idiopathic inflammatory bowel disease or systemic vasculitis. CONCLUSION: Proctosigmoiditis caused by myointimal hyperplasia of mesenteric veins and idiopathic proctosigmoiditis may present in a similar fashion. Although patients with myointimal hyperplasia of mesenteric veins do not respond to medical management, segmental resection is usually curative, and long-term drug therapy or even proctocolectomy can be avoided. physicians should consider the possibility of myointimal hyperplasia of mesenteric veins when patients with apparent idiopathic proctosigmoiditis do not respond to medical therapy.

3/110. prothrombin 20210G/A mutation in two patients with mesenteric ischemia.

    Primary cases of splanchnic vein thrombosis are now less common since a systematic screening for hypercoagulability is performed. In 1996, a sequence variation in the 3'-untranslated region of the prothrombin gene (F.II 20210G/A mutation) has been linked to a threefold increased risk for venous thrombosis. The role of this thrombophilic disorder is not documented in patients with thrombosis of the splanchnic veins. This report presents two patients with a mesenteric ischemia associated with a heterozygous state for the F.II 20210G/A mutation. The first patient developed an ischemic colitis and the second one an ischemic necrosis of the terminal ileum related to a thrombosis of the superior mesenteric vein. In both cases, another thrombotic risk factor was associated: either a general prothrombic state (primary antiphospholipid syndrome) or a focal factor (abnormal hemodynamic conditions related to a liver cirrhosis). It has recently been proposed that several conditions need to be combined for deep vein thrombosis to develop. Screening for the combination of multiple underlying prothrombotic conditions thus appears justified in patients with splanchnic thrombosis. The role of the F.II 20210G/A mutation as a predisposing factor for thrombosis of the digestive vessels should be considered and needs further investigation.

4/110. Type I acute aortic dissection accompanied by ischemic enterocolitis due to blood flow insufficiency in the superior mesenteric artery.

    We report a case of acute type I aortic dissection with ischemic enterocolitis due to blood flow insufficiency in the superior mesenteric artery. The patient was a 52-year-old man who visited the hospital with major complaints of sudden low back pain and melena. Mesenteric ischemia was suspected, and angiography revealed type I aortic dissection with accompanying blood flow insufficiency in the superior mesenteric artery. Because catheterization during angiography improved the blood flow disorder and prevented intestinal necrosis, it was possible to replace the ascending aorta with a prosthetic graft. Arterial pulsation in the mesentery was recovered by the operation and the patient's life was saved without bowel resection. This case demonstrates that prompt surgical or percutaneous relief of ischemia in major organs is important to save lives in the cases of acute aortic dissection with ischemic complications.

5/110. Gastrointestinal complications of aortic bypass surgery.

    Gastrointestinal bleeding following abdominal aortic bypass surgery is not uncommon, as approximately 20% of patients with abdominal aortic aneurysms have peptic ulcer disease. We have recently seen three patients who presented with gastrointestinal bleeding secondary to the complications of their surgery. The cause of the bleeding was aortoduodenal fistula, graft erosion into the sigmoid colon and ischaemic colitis respectively. The correct diagnosis was only considered in one patient, although in retrospect it should have been suggested in all three. Our experiences with these complications and their clinical and radiological presentation form the basis for this paper.

6/110. Ischemic colitis during treatment with alosetron.

    irritable bowel syndrome (IBS) is one of the most common entities observed by both primary care physicians and gastroenterologists. Alosetron is a potent and selective serotonin antagonist that recently became the first food and Drug Administration-approved agent for diarrhea-predominant IBS. However, since approval, significant side effects have been noted with the use of alosetron including severe constipation, fecal impaction, and ischemic colitis. We describe a case of ischemic colitis in a male patient with IBS who was briefly treated with alosetron. Clinical, endoscopic, and pathologic features of the focal colitis strongly suggested ischemia. Symptoms correlated temporally with alosetron use, and symptoms abated with discontinuation of the drug. Endoscopic and pathologic resolution of the colitis were documented.

7/110. Percutaneous stenting of an latrogenic superior mesenteric artery dissection complicating suprarenal aortic aneurysm repair.

    PURPOSE: To report endovascular repair of an iatrogenic superior mesenteric artery (SMA) dissection caused by a balloon occlusion catheter. CASE REPORT: A 68-year-old man with a suprarenal aortic aneurysm underwent conventional prosthetic replacement, during which visceral artery back bleeding was controlled with balloon occlusion catheters. Six hours postoperatively, the patient experienced an episode of bloody diarrhea with abdominal pain and tenderness and mild metabolic acidosis. colonoscopy revealed colitis (grade I) without necrosis of the right and left colon. An emergent abdominal computed tomographic scan showed signs of mesenteric ischemia with bowel dilatation and SMA wall hematoma; angiography identified a dissection 1 cm distal to the SMA origin. An Easy Wallstent was deployed percutaneously, successfully reestablishing SMA patency. The postoperative course was uneventful, and the patient remains asymptomatic with a patent SMA stent and aortic graft at 1 year. CONCLUSIONS: latrogenic SMA dissection should be suspected after suprarenal aortic aneurysm repair if signs of mesenteric ischemia arise. Prompt and thorough imaging studies are necessary to confirm the diagnosis and assess the potential for an endoluminal treatment.

8/110. Severe gastrointestinal haemorrhage and ischaemic necrosis of the small bowel in a child with 70% full-thickness burns: a case report.

    Splanchnic ischaemia is an important problem in patients with large burns. This reports the case of an 11-year-old boy with 70% full-thickness TBSA burns who sustained multiple episodes of severe gastrointestinal haemorrhage due to both extensive ischaemic enterocolitis and severe gastric ulceration which required surgical intervention on several occasions. Causative mechanisms of splanchnic ischaemia in this patient including increased mesenteric vascular resistance, abdominal compartment syndrome and enteric feeding, are considered.

9/110. Ischemic colitis after abdominoperineal resection.

    Four cases of ischemic colitis occurring at intervals from 3 months to 7 years after abdominoperineal resection are described. In 3 of the 4 cases patency of the direct arterial supply to the ischemic segment was documented. The lack of collateral circulation provided by the resected colon probably increases the risk of developing ischemic colitis in the remaining colon.

10/110. femoral neuropathy and ischemic colitis associated with amyloidosis in hemodialysis patients.

    Renal failure is often the presenting problem with amyloidosis and it portends a generally poor prognosis. Two of 121 patients in a home dialysis program were found to have amyloidosis after they developed unusual complications, ischemic colitis and femoral neuropathy. Both ultimately died as a result of their disease. From the limited experience that is reported, it appears that renal transplantation offers a better alternative for long term therapy than hemodialysis.
