The experience of acute mesenteric ischaemia at St Vincent's Hospital, Melbourne, has been reviewed over 17 years. The mortality remains appallingly high. This applies particularly to those patients who had thrombosis of the superior mesenteric artery, amongst whom the mortality in this series was 97%. The mortality was slightly less in the group suffering from embolic occlusion of the superior mesenteric artery (66%), and in those suffering from thrombosis of the superior mesenteric vein (60%). A mortality of 66% was also found in patients suffering from non-occlusive gut ischaemia. Delay in diagnosis accounted for this high mortality. Early diagnosis is all-important, and this depends on the performance of mesenteric angiography in any patient suspected of having mesenteric ischaemia. Appropriate surgery may then be carried out in the occlusive group and supportive treatment, including intraarterial papaverine infusion, given to those with non-occlusive ischaemia. There is a pressing need for simple non-invasive tests to segregate those patients suffering from acute mesenteric ischaemia from those whose acute abdomen is due to some other cause.

The diagnosis of acute superior mesenteric artery occlusion in the dog has been achieved in every case by isotope scanning of the abdomen using technetium-labelled red cells or technetium-labelled human serum albumin. The white cell count is also significantly elevated, but the changes in the levels of the enzymes CPK, LDH, AST and serum amylase are not specific for actue mesenteric ischaemia. In the human the presence of a normal gut circulation can be demonstrated by isotope scanning provided that the patient is not severely shocked. The presence of a normal gut circulation as shown on the scintigram conclusively eliminates the possibility of acute main trunk occlusion of the superior mesenteric artery. This should be of help in differentiating acute occulusive mesenteric ischaemia from other causes of the acute abdomen. Abdominal scintiscanning is complementary to angiography, which still remains the most precise means of diagnosing acute mesenteric ischaemia. Although the abdominal scintigram is more limited in its application and is not as accurate as angiography, it is quicker to perform, non-invasive, and entirely safe. Abdominal scintiscanning is an excellent screening test to be used in patients suspected of suffering from acute occlusive mesenteric ischaemia.

86 plain films of the abdomen from 63 patients with acute mesenteric infarction were compared with plain films of 90 patients with acute abdomen of different origin. The airless abdomen, the increased thickness of the gut wall and the hairpin sign proved tbe nonspecific, but more pronounced and more frequent in mesenteric infarction. Gas in the gut wall and in the portal vein system was found only in mesenteric infarction. All 6 patients with gas in the portal veins died. The airless abdomen in a patient with severe abdominal pain is a surprising finding and points to the possibility of mesenteric infarction.

Eight cases of abdominal tuberculosis from the Department of Medicine, Singapore General Hospital are reported to illustrate the varied clinical manifestations of the disease. Presentation ranged from asymptomatic hepatomegaly to acute abdomen (intestinal obstruction/perforation). Chronic non-specific symptomatology (fever, weight loss, abdominal pain, diarrhoea, jaundice) was commonest. There were three patients with hepatic tuberculosis, two with tuberculous mesenteric lymphadenitis and three with intestinal tuberculosis, two of whom had concomitant tuberculous peritonitis. Only three patients had coexisting pulmonary tuberculosis. The diagnosis was unsuspected at presentation in four patients. Initial provisional diagnoses included typhoid, abdominal lymphoma, hepatic malignancy, chronic hepatitis and iatrogenic gut perforation. All patients responded totally to conventional antituberculous therapy.

Rotational gut abnormalities are generally considered a disease process of the neonatal and pediatric populations. However, they may first become manifest in teenagers and adults, often with disastrous outcomes. A case of a 15-year-old boy who presented in shock with an acute abdomen is presented. His symptoms had been mistaken for 1 week as gastroenteritis. At surgery, he was found to have a midgut volvulus. A differential diagnosis is discussed, as well as an anatomical review and typical symptomatology associated with midgut abnormalities.

Small bowel lymphomas account for 20 to 40% of primary gut lymphomas in Western populations and are among the most common malignant tumours of the small bowel. We studied 119 cases of primary small bowel lymphoma presenting over 4 decades. Two thirds of the patients were men with a peak age incidence in the 7th decade. Common presenting features included abdominal pain, weight loss, small bowel obstruction, and acute abdomen. Tumours were classified using the Kiel European Association for Haematopathology Geneva Workshop scheme and phenotyped on paraffin sections; 66% were B cells, and 34% were T cell. In all cases, the antibodies L26 and polyclonal CD3 reliably distinguished between B- and T-cell tumours. Of the B-cell lymphomas, 62% were diffuse high grade, 20% were low-grade lymphomas of mucosa-associated lymphoid tissue, 11% had both low- and high-grade components, and 7% were other low-grade types. Of the T-cell lymphomas, 83% were high grade, and 49% were enteropathy associated. Most T-cell lymphomas were ulcerated plaques or strictures in the proximal small bowel; B-cell lymphomas tended to be annular or polypoid masses in the distal and terminal ileum. Survival data showed that low-grade B-cell lymphomas had the best outcome and T-cell lymphomas the worst. Adverse prognostic features included perforation, high-grade histology, multiple tumours and advanced stage.

In the period 1946-1987 at the former Second Surgical Clinic of the Medical Faculty in Belgrade 25 patients with a biliary ileus were Surgically treated, 20 females (80%), and 5 males (20%), aged from 53 to 87 years, (mean 67 years). Six patients were decade, 7 in 7th, 9 in 8th, and 3 in 9th decade. In only 8 patients biliary calculosis had been confirmed earlier. Preoperative troubles in the Bowel Passage lasted 1-7 days, (mean 3 days), mostly as in incomplete gut occlusion. Preoperative diagnosis of the biliary ileus, using x-ray, was exact only in 3 cases (12%), while other remaining patients underwent Surgery diagnosed as ileus of the small bowel or acute abdomen. In 7 patients a stone obstructed the jejunum, in 6 ones its widpart and in 10 cases the terminal ileum. In 23 patients an enterotomy distally to the obstruction with an expulsion-extraction was done, in one patient a partial resection of the gut and in another patient a manual stone expulsion into the colon, with no enterotomy, was carried out, and after operation the stone was removed from the rectum. The Bilio-digestive fistula was never treated either the surgery itself, or later. Complications arised in 13 patients: wound infection in 11, deep thrombophlebitis in one and a pneumonia in two patients. An average hospitalization was 27 days, and all patients Survived.

The high diagnostic ability of sonography for the solid organs of the upper abdomen and the biliary and genitourinary tract is well established. The gut on the other hand has been more or less ignored by many sonographers in routine abdominal screening and evaluation of the acute abdomen. This is regrettable because sonography, like CT, is an excellent modality for assessing mural abnormalities of various origin (i.e. neoplastic, inflammatory, ischemic or hemorrhagic), as well as possible involvement of the adjacent soft tissues and solid organs. Considerable sonographic skill and "tenacity" and an adequate equipment are however indispensable to achieve high diagnostic reliability in the detection and interpretation of abnormalities of the G-I tract. Our own and other's experience suggest that the time devoted to sonographic screening of the gut is very worthwhile especially in acute clinical conditions. Acute appendicitis is one of the typical examples where sonography has found widespread acceptance. This article reviews the application of graded compression sonography in the evaluation of appendicitis, for using on technique, diagnostic criteria, and differential diagnosis.

Anisakis pathology is due mainly to two mechanisms: allergic reactions (from isolated urticaria and angioedema to life-threatening anaphylactic shock associated with gastrointestinal symptoms or 'gastroallergic anisakiasis'), and direct tissue damage, due to invasion of the gut wall, development of eosinophilic granuloma, or perforation (gastric or intestinal anisakiasis). Anisakiasis is a misdiagnosed and underestimated cause of acute abdomen: most patients undergo laparotomy, and virtually no cases are diagnosed before surgery. In some cases, diagnosis is obtained accidentally during other pathologic investigations. We report a case of acute abdomen due to terminal ileum involvement. Microscopic examination of the resected segment showed the presence of helminthic sections consistent with larvae of Anisakis spp. A history of raw fish ingestion was recorded. Histopathologic features are illustrated. A short but up-to-date review of the literature on diagnostic devices (particularly imaging and serology), clinical aspects and therapy is presented.
