1/405. Pouching a draining duodenal cutaneous fistula: a case study. Blockage of the mesenteric artery typically causes necrosis to the colon, requiring extensive surgical resection. In severe cases, the necrosis requires removal of the entire colon, creating numerous problems for the WOC nurse when pouching the opening created for effluent. This article describes the management of a draining duodenal fistula in a middle-aged woman, who survived surgery for a blocked mesenteric artery that necessitated the removal of the majority of the small and large intestine. Nutrition, skin management, and pouch options are described over a number of months as the fistula evolved and a stoma was created. ( info) |
2/405. Post-traumatic thrombosis of a segmental branch of the inferior mesenteric vein. We report the case of man with post-traumatic thrombosis in a segmental branch of the inferior mesenteric vein with secondary venous congestion and ischemia of the sigmoid colon. We discuss the current imaging modalities for diagnosing venous thrombosis and their relative significance. ( info) |
3/405. Superior mesenteric vein stenosis complicating Crohn's disease. BACKGROUND: Superior mesenteric vein stenosis as a consequence of mesenteric fibrosis, causing the development of small bowel varices, is an unrecognised association of Crohn's disease. case reports: Two cases of gastrointestinal bleeding occurring in patients with Crohn's disease, and a third case, presenting with pain and diarrhoea, are described. In all three patients, visceral angiography showed superior mesenteric vein stenosis with dilatation of draining collateral veins in the small bowel. Overt gastrointestinal bleeding or iron deficiency anaemia resulting from mucosal ulceration is common in Crohn's disease, but acute or chronic bleeding from small bowel varices as a result of superior mesenteric vein stenosis due to fibrosis has not previously been reported.

4/405. Gastric intramucosal pH as a monitor of gut perfusion after thrombosis of the superior mesenteric vein. Gastric intramucosal pH (pHi) when measured by a tonometer is a simple and minimally invasive method to determine gut ischemia. In a case of severe mesenteric venous thrombosis, we measured pHi intra- and postoperatively over a period of five days. The goal was to monitor improvement or deterioration of gastrointestinal perfusion in the intensive care unit and to perform a second-look laparotomy if the condition worsened. We observed that gastric pHi is a more sensitive parameter for detecting intestinal ischemia than parameters such as arterial pH, base excess, or lactate. This patient's pHi rose continuously, which allowed us to proceed in a conservative way without any further invasive diagnostic interventions. Thus, the application of a gastric tonometer in cases of mesenteric venous thrombosis may help to reduce costs by preventing unnecessary postoperative diagnostic maneuvers such as angiography, computed tomography, or even second-look laparotomy.

5/405. Mesenteric and portal vein thrombosis in a young patient with protein s deficiency treated with urokinase via the superior mesenteric artery. A 32-year-old man, who was previously healthy, had acute abdominal pain without peritonitis. Diffuse mesenteric and portal vein thrombosis were shown by means of a computed tomography scan. A protein s deficiency was found by means of an extensive workup for hypercoagulable state. Successful treatment was achieved with urokinase infusion via the superior mesenteric artery without an operation. This represents an attractive alternative approach to treating patients with this disease. The previous standard of operative intervention(1) can now be reserved for complications, such as bowel infarction with peritonitis, or for those patients with absolute contraindications to thrombolytic therapy.

6/405. 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.

| A patient, suffering from angina pectoris, claudicatio intermittens and postprandial abdominal pain underwent coronary and peripheral arteriographic examination; coronary arterial disease and aortoiliac occlusive disease was diagnosed. color Doppler ultrasonography revealed superior mesenteric artery stenosis. CABG with MIDCAB (minimal invasive direct coronary artery bypass) technique was performed together with aortabifemoral graft interposition and graft bypass to superior mesenteric artery and considerable success was obtained.

8/405. Idiopathic mesenteric thrombosis following caesarean section. Mesenteric venous thrombosis, "the great mimicker", is a very rare disorder in pregnancy and the puerperium, particularly when not associated with any pre-existing thrombophilia or autoimmune states. We describe a patient requiring a resection of 150 cm of gangrenous small bowel after uncomplicated elective Caesarean section. The only risk factor for thrombosis was recovery from an elective Caesarean section, a condition classified by the Royal College of Obstetricians and Gynaecologists as "low risk". death from thromboembolism is the leading cause of maternal mortality and should always be considered with unusual post partum symptoms. early diagnosis of mesenteric vascular occlusion is difficult and recent evidence suggests that elevated GST isoenzyme may be helpful. In all cases of MVT anti-coagulation is the basis of treatment. patients who are not anti-coagulated after surgery have a recurrence rate of 25 per cent compared with 13 per cent of heparinised post-operative patients. As no other pre-existing cause for MVT was found, management was with warfarin for 6 months, the oral contraceptive pill was contraindicated and heparin prophylaxis was recommended for future pregnancies.

9/405. Superior mesenteric artery stenting for mesenteric ischaemia in Sneddon's syndrome. Mesenteric ischaemia is a rare but serious cause of abdominal pain. We present the case of a man with Sneddon's syndrome, who had symptomatic mesenteric ischaemia secondary to a superior mesenteric artery stenosis in conjunction with a hepatic artery stenosis. As far as the authors are aware, this has not previously been described in Sneddon's syndrome, which is a vascular systemic disease characterized by an association between cerebrovascular accidents and a livedo reticularis skin rash. He was treated with balloon angioplasty and stent insertion, with good symptomatic improvement. This has implications for other stenoses in this condition should they become symptomatic. ( info) |
10/405. An unusual complication of appendicitis in childhood. Mesenteric venous thrombosis has not been reported after an appendicectomy in the pediatric literature. We report on a special and very unusual complication in a girl who presented mesenteric venous thrombosis (MVT) following an appendicectomy for gangrenous appendicitis. The early diagnosis of this entity is vital in order to start the anticoagulation treatment which could allow preservation of bowel viability. The therapy should be continued for a long time to decrease the risk of relapse. ( info) |
