A 25-year-old Japanese woman who had been suffering from systemic lupus erythematosus (SLE) for 12 years was admitted to our hospital with a suspected diagnosis of peritonitis after suddenly developing severe abdominal pain and distention which could not be relieved by treatment with anodyne. Noninvasive examinations did not provide enough evidence to rule out acute appendicitis, bowel perforation, or ischemia due to vasculitis. Therefore, in consideration of the severity of her uncontrollable abdominal pain, an exploratory laparotomy was performed. The operative findings revealed nonbacterial peritonitis with a large amount of ascites and an edematous small bowel. No perforation of the intestine was found. On post-operative day (POD) 3, the severe abdominal pain redeveloped, but responded well to steroid pulse therapy. Based on the operative findings and her clinical course, the most likely diagnosis was thought to be acute lupus peritonitis. It is often difficult to ascertain whether abdominal pain in an SLE patients is due to lupus peritonitis or to an underlying cause requiring surgery. Thus, it is essential that continuous and careful assessment of the surgical abdomen is performed when a patient with SLE develops acute abdominal pain, and if a surgical condition cannot be ruled out, a laparotomy should be performed without delay.

The dissection is termed Type A according to the Stanford classification, if the ascending aorta is involved. It is termed type B, if the ascending aorta is not involved. Most patients with Type A aortic dissection die from intrapericardial rupture with cardiac tamponade, free pleural rupture, massive aortic regurgitation, or coronary or cerebral malperfusion (ischemic heart disease or stroke). Most patients with Type B dissection die from free pleural rupture or renal or visceral vascular complications. The resultant compromise of various aortic branches (inomunate, carotid, subclavian, spinal, renal, superior mesentric, or iliac arteries) results in a wide variety of symptoms and signs (shock, dyspnea, stroke, paraplegia, anuria, abdominal pain or extremity ischemia).

The authors report the cases of two patients presenting a symptomatic intestinal angina caused by median arcuate ligament compression. Arteriography demonstrates severe coeliac artery stenosis in both of them and a retrograde filling of the coeliac axis from the superior mesenteric artery branch collateral vessels. The patients became asymptomatic after surgical release of the celiac trunk by section of the median arcuate ligament of the diaphragm. At 2 and 3 years follow-up, both patients report no further abdominal pain. Dunbar's syndrome is still a questionable subject; how can be a narrowing or an occlusion of the celiac artery semeiotically and clinically important? Some have proposed an ischemic base to explain the abdominal pain: the compression of the celiac trunk could be responsible of a celiac steal which results in shunting of blood from the superior mesenteric artery to the celiac distribution through the collateral system. There are very strong proofs that partial or even complete obstruction of the celiac artery should not lead to visceral ischemia such as: the rich collateral anastomosis of the celiac axis, the surgical ligation of the celiac axis performed without untoward consequences, the finding of asymptomatic celiac stenosis in the 49% of an arteriographic study, impossibility to formulate a consistent and rational for the surgical results. Shearing this view, few authors would prove that a stenotic type of the celiac artery is only a normal anatomic variant, refuting the existence of this syndrome.

From twenty six personal cases, the authors make a review of the literature. 92% of their cases are met in a post operative (28%), neurological (28%), general (24%) context, or in intensive care with assisted ventilation (36%). The major symptom is the meteorism (100%) with in one out of three cases, abdominal pain, vomiting, right iliac defense, absence of bowel sounds. Radiological distension involves mostly the right colon and the coecum (28%), right and transverse colon (40), sometimes the whole colon (32%). The mean diameter of the coecum reached 12 cm (9 to 25 cm). Early coloscopy was mandatory in 20 patients, of which 14 were cured, 13 patients were operated on, for suspicion of ischemia or perforation, because incertain diagnosis, or failure of colonoscopy. Ceocostomy or right hemicolectomy (55%) were performed rather than transverse colostomy. The surgical approach must be adapted to the anatomical lesions. Total mortality was 4% in this series. Early diagnosis of pseudo obstruction, early colonoscopy with intubation must allow to avoid surgery.

Duplex ultrasonography accurately identifies high-grade stenoses in the SMA. Analysis of velocity data reveals few false positives and virtually no false negatives in the determination of high-grade SMA stenosis by duplex scanning. We therefore utilize duplex scanning to perform early screening studies of patients with symptoms suggestive of chronic visceral ischemia. If the duplex findings are negative, we recommend evaluating for other sources of abdominal pain. If the findings are positive, prompt angiography is indicated. It is important to remember that although duplex scanning can identify mesenteric artery stenosis, it cannot diagnose intestinal ischemia. By establishing duplex scanning as a useful and accessible noninvasive screening tool, it is hoped that the time between onset of visceral ischemic symptoms and diagnosis of chronic visceral ischemia will be shortened significantly, potentially reducing the morbidity and mortality of the disease.

Owing to a heightened awareness of the disease as well as improved diagnostic tests, chronic mesenteric ischemia is now recognized as a more common cause of abdominal pain. The classic symptoms of postprandial abdominal pain with weight loss are evident in the majority of proven cases; most patients also have other evidence of advanced atherosclerotic vascular disease. Several new diagnostic techniques are being developed and tested, most notably color duplex imaging, although angiography still remains the diagnostic gold standard. It is hoped that better noninvasive testing may eventually eliminate the need for angiography, as well as lead to a more expedient diagnosis of chronic mesenteric ischemia.

Compression of the visceral arteries can produce true mesenteric ischemia, but the syndrome is rare. The syndrome is caused by unfavorable anatomic relationships at the aortic hiatus among the CA, the SMA, and overlying structures, particularly the diaphragmatic crura. These anatomic relationships, in contrast to the syndrome they sometimes produce, are relatively common, which makes the detection of CA compression only a prerequisite to the diagnosis of the clinical entity. The diagnosis of CA compression syndrome ultimately depends on the relentless elimination of other possible causes for abdominal pain and on the knowledge that this curious syndrome does indeed exist. If properly diagnosed, the CA compression syndrome can be corrected with a safe, relatively simple surgical procedure. Past treatment series reflect too little appreciation for the extensiveness of a true, chronic CA injury. Revascularization of the CA, in addition to release of compression, should therefore be performed with greater frequency in the future. The young patients who are successfully diagnosed and treated for this unusual syndrome are frequently entirely relieved of long-standing, debilitating pain, and, like other patients with chronic mesenteric ischemia, they typically enjoy dramatic improvement in the quality of their lives. Thus, with the prospect of these patients in mind, a clinician should accept the opinion that the syndrome "does not exist" only after careful consideration of the entire literature.

We describe a 39-year-old woman with an 8-month history of abdominal pain, diarrhea, and weight loss. Clinical and laboratory evaluation indicated the presence of a malabsorption syndrome. Endoscopy revealed multiple gastric ulcerations and an abnormal "picture" of the duodenal mucosa. At duodenal biopsy, necrosis confined to the distal parts of the enteric villi and a polymorphonuclear leukocyte response were found. Further evaluation revealed intestinal ischemia as a result of mesenteric atherosclerosis. After a revascularization procedure was performed, the symptoms disappeared. The macroscopic and microscopic picture of the bowel normalized. In our search for risk factors of atherosclerosis, we found a substantially increased basal plasma homocysteine concentration. This case suggests that hyperhomocysteinemia may have a causal role in the development of symptomatic, premature atherosclerosis of the mesenteric circulation.

Extrahepatic portal vein thrombosis (EHPVT) is the leading cause of variceal hemorrhage in patients with healthy livers; however, in an era of dynamic imaging, the incidental discovery of EHPVT places a special burden on the surgeon to understand the surgical implications of the disease in this setting. During the period 1989 to 1995, 23 patients (12 males and 11 females) were found to have EHPVT. In 20 (87%), this was an unexpected finding on ultrasound (11 of 23), abdominal CT scan (9 of 23), or both (9 of 23). In two patients, the diagnosis was suspected and confirmed with angiography, whereas in the other, the lesion was discovered at surgery. Only seven (30%) had hemorrhage as a presenting complaint. More typically (61%), abdominal pain alone or pain with sepsis was the indication for evaluation. In 20 patients (87%), there was an identifiable etiology for the EHPVT. A total of 15 operations were performed on 12 patients (52%), in 7 (4, variceal hemorrhage, and 3, bowel ischemia) as a direct consequence of the EHPVT and in five, for conditions not directly related to the EHPVT. Three of the 23 patients (13%) died, two (17%) following surgery and one (9%) from advanced malignant disease. No patients with hemorrhage (seven), even those who required a shunt for decompression (three) or devascularization (one), died. We found that the diagnosis of EHPVT is usually not related to variceal hemorrhage, but rather, abdominal symptoms that serve as an indication for the imaging study. Three subsets of patients emerged: (1) those requiring no surgery (11 patients), (2) those requiring surgery related to hemorrhage (4 patients), and (3) those requiring surgery for conditions other than varices (8 patients). In any of these circumstances, mortality (13%) was related to the underlying disease process rather than EHPVT. Given the earlier recognition of EHPVT, the natural history of the disease has been altered, with outcome reflecting the underlying disease rather than the sequelae of portal hypertension.

We report our experience in 88 cases of ischemic colitis including 76 cases of gangrene with 17 perforations, 6 cases with stenosis and 6 cases which regressed. The left colon was involved in 59 cases with extension to the transverse colon in 20 the right colon in 10 and global involvement in 18. Abdominal pain, diarrhea, and meteorism occurred in 81, 62 and 78% of the cases respectively. Coloscopy was performed in 61 cases, a barium study in 27. A colectomy was required in 77 patients: 50 left colectomies with 16 extensions to the transverse colon, 17 total colectomies and 10 right colectomies. Morbidity was 53% in cases with perforated gangrene and 28% without perforation. There was no morbidity in stenosis and regressive forms. Normal tube flow was conserved or reestablished in 51 of the 62 survivors. The 88 patients were referred from cardiovascular units (36%), intensive care (28.5%), or internal medicine (22%). All had intramural ischemia due to local or general lesions which progressed to parietal gangrene in 76 cases. The diagnosis was based on clinical signs and confirmed by coloscopy which determined the stage and extension. Stage II ischemia required rapid colectomy adapted to the endoscopic lesions and not the exterior aspect of the colon; immediate anastomosis is usually not used.
