Somatostatin is present in the gastrointestinal tract in appreciable amounts. The highest concentrations of the polypeptide are found in the stomach, the upper small intestine, and the pancreas. Within the gastrointestinal tract, somatostatin inhibits various functions, including endocrine and exocrine secretion, motility, blood flow, absorption, and growth. The polypeptide regulates these functions by endocrine, paracrine, neurocrine or luminal mechanisms. Abnormalities of endogenous somatostatin have been implicated in several gastrointestinal disorders, including the somatostatinoma syndrome, antroduodenal D-cell hyperplasia, peptic ulcer, obesity, and liver cirrhosis. Because of its potent inhibitory effects, somatostatin or somatostatin-analogues have been used as therapeutic agents in various clinical conditions, such as upper gastrointestinal haemorrhage, endocrine pancreatic tumours, gastrointestinal and pancreatic fistulas, pancreatitis, secretory diarrhoea, and dumping syndrome. The recent availability of the synthetic long-acting somatostatin-analogue SMS 201-995 (Sandostatin) has greatly facilitated the therapeutical application of somatostatin-polypeptides.

Because of its wide distribution in the organism, natural somatostatin (SRIF) demonstrates an ample spectrum of actions, involving mainly the central neuroendocrine system and the enteropancreatic area. In the former, this peptide may find its field of application in conditions characterized by excessive GH, TSH or ACTH secretion, depending on the central or peripheral cause of the inappropriate hormone control. The inhibitory effect of SRIF on gastrointestinal and pancreatic hormones may be useful in the management of tumors originating in this system and also in the treatment of inflammatory processes such as pancreatitis, in malignant diarrhea, and in gastrointestinal bleeding. A complex action of SRIF and its derivative on insulin release and glucose homeostasis may offer some advantages in the control of unstable diabetes. Dampening of organic functions in the upper digestive tract may also render SRIF and its analogues useful in the exploration of the gallbladder, gastric and pancreatic functions. The effect of such peptides on tissue growth and on the regulation of blood pressure are the subject of present investigations. Cytoprotection, an interesting aspect of SRIF application, is discussed elsewhere in this compendium. Finally, some comments on the possible use of SRIF as an additive to the conventional treatment of burns and sepsis close this review.

Pancreatic abscess was diagnosed by exploratory celiotomy in 6 dogs. The most common clinical signs included acute onset of lethargy (n = 5), anorexia (n = 6), vomiting (n = 5), and diarrhea (n = 2). Physical examination revealed pain response to abdominal palpation (n = 5), depression (n = 5), icterus (n = 3), fever (n = 3), and cranial abdominal mass (n = 2). Consistent preoperative clinicopathologic abnormalities included leukocytosis with left shift, observance of toxic neutrophils on the blood smear, hyperlipasemia, hyperamylasemia, hyperbilirubinemia, and increased serum alkaline phosphatase activity. In 5 of 6 dogs, abdominal radiography revealed increased soft tissue density in the cranial portion of the abdomen. Ultrasonography performed on 4 dogs confirmed pancreatic mass. In all dogs, exploratory celiotomy revealed a cavitary pancreatic mass that contained sterile, mucopurulent material. Histopathologic diagnoses included acute necrotizing or chronic-active pancreatitis and steatitis. Two dogs were euthanatized at the time of diagnosis, and the remaining 4 were treated by use of pancreatic debridement(s), open abdominal drainage, and intensive administration of fluids and antibiotics. One dog was euthanatized 4 days after surgery, because of progressive pancreatic abscessation. Three dogs recovered and were discharged.

A primate lymphotropic lentivirus was isolated on the human T-cell line HuT 78 after cocultivation of a lymph node from a pig-tailed macaque (Macaca nemestrina) that had died with malignant lymphoma. This isolate, originally designated M. nemestrina immunodeficiency virus (MnIV) and now classified as simian immunodeficiency virus (SIV/Mne), was inoculated intravenously into three juvenile rhesus monkeys (Macaca mulatta), three juvenile pig-tailed macaques (M. nemestrina), and two juvenile baboons (Papio cynocephalus). All six macaques became viremic by 3 weeks after inoculation, whereas neither of the baboons developed viremia. One pig-tailed macaque died at 15 weeks with suppurative peritonitis secondary to ulcerative, necrotizing colitis. Immunologic abnormalities included a marked decrease in CD4+ peripheral blood lymphocytes. Although five macaques mounted an antibody response to SIV/Mne, the animal that died at 15 weeks remained antibody negative. Three other macaques (two rhesus and one pig-tailed) died 66 to 87 weeks after inoculation after exhibiting progressive weight loss, anemia, and diarrhea. Histopathologic findings at necropsy included various manifestations of immune deficiency, nephropathy, subacute encephalitis, pancreatitis, adenocarcinoma, and lymphoid atrophy. SIV/Mne could be readily isolated from the spleens and lymph nodes of all necropsied macaques, and from the cerebrospinal fluid, brains, bone marrow, livers, and pancreas of some of the animals. SIV antigens were localized by avidin-biotin immunohistochemistry to pancreatic islet cells and to bone marrow endothelial cells. The data suggest that African baboons may be resistant to infection by SIV/Mne, whereas Asian macaques are susceptible to infection with this pathogenic primate lentivirus.

Sixteen patients were treated for gastrocolic fistula arising as a complication of peptic ulcer (11 cases), colonic perforation (2), gastric cancer (1), colonic cancer (1) or pancreatitis (1). The predominant symptoms were diarrhoea, weight loss and abdominal pain. Barium meal and barium enema were the most reliable means of diagnosis, and no fistula was gastroscopically demonstrable. A one-stage en bloc resection of the involved gastrocolic region was performed in eight cases. Other operations were simple excision (3), gastric resection with closure of the colonic wall (2) and colectomy with closure of the gastric wall (2). In one case cure was achieved with cimetidine, without surgical intervention. Four patients died postoperatively and two had recurrence of fistula.

A 30-year-old man returning from a trip through India complained of epigastric pain, diarrhea, loss of weight, and jaundice. Stool examination was positive for Strongyloides stercoralis. On ultrasonographic investigation, intravenous cholangiography, and endoscopic retrograde cholangiopancreaticography, stenosis of the distal common bile duct and enlargement of the pancreatic head were observed. The patient was treated for the Strongyloides infection. The jaundice disappeared within days, the laboratory finding normalized, and the patient recovered rapidly. However, the ultrasonographic examination showed a complete recovery in the course of about 2 years. From this report we conclude that in patients with obstructive jaundice and Strongyloides stercoralis infection, serious abnormalities resembling pancreatic tumour or pancreatitis can be found on ultrasonographic and radiological investigations, and this should be considered in the differential diagnosis of pancreatic mass in patients living in or returning from endemic areas.

Spontaneous bacterial peritonitis (SBP), a fascinating disease that had been reported perhaps 50 times in varying guises over the preceding century, suddenly burst forth in the 1960s and was recognized in clusters of cases almost simultaneously in Paris, London, and West Haven, Connecticut. The spectrum of the disease has broadened. Initially, it was associated almost exclusively with alcoholic cirrhosis, but it has now been found in association with posthepatitic cirrhosis, cryptogenic cirrhosis, chronic active liver disease, and, occasionally, in biliary cirrhosis and cardiac cirrhosis. Recently, it has been reported in alcoholic hepatitis and acute viral hepatitis. It occurs occasionally in malignant ascites and in pancreatitis in the absence of cirrhosis. It is surprisingly common in disseminated lupus, in which it occurs relatively more commonly than in alcoholic cirrhosis. A similar syndrome, primary peritonitis, occurs frequently in children with nephrotic ascites. The clinical pattern of SBP has broadened. Initially it consisted of abdominal pain, fever, rebound tenderness, hypoactive bowel sounds, hypotension, encephalopathy, and cloudy ascites with large numbers of polymorphonuclear leukocytes in ascitic fluid. Each and every symptom, sign, and laboratory abnormality may be absent; indeed, the syndrome can be completely silent. Initially, the causative bacteria appeared to be almost exclusively enteric, but now the list of bacteria isolated in cases of SBP looks like a bacteriology textbook. Anaerobes are rare. Multiple organisms usually suggest nonspontaneous origin such as perforation or vasopressin induction. The differentiation between spontaneous and nonspontaneous bacterial peritonitis is crucial in the differential diagnosis. The great majority of cases of SBP develop in the hospital, 80% more than one week after admission. It is therefore a nosocomial disease that may be precipitated by procedure-induced bacteremia, gastrointestinal bleeding, or diarrhea, and it tends to occur in patients with low ascitic fluid protein (complement) concentrations and severe portal-systemic shunting.

Plasma concentrations of peptide YY (PYY), a newly isolated peptide produced by ileal and colonic endocrine cells, were measured in several groups of patients with digestive disorders after a standardized normal breakfast. Peptide YY levels were found to be grossly elevated in patients with steatorrhea due to small intestinal mucosal atrophy (tropical sprue). Basal levels in these patients were 79 +/- 18 pM, which was nearly 10-fold higher than those seen in healthy controls (8.5 +/- 0.8 pM). Patients with steatorrhea due to chronic destructive pancreatitis also had substantially increased basal PYY levels (47.5 +/- 6.3 pM), and their postprandial response was also greater than that of normal subjects. Moderately elevated plasma PYY concentrations were seen in patients with inflammatory bowel disease and patients recovering from acute infective diarrhea. In contrast, patients with diverticular disease, duodenal ulcer, and functional bowel disease had normal PYY responses. These changes in the secretion of PYY responses. These changes in the secretion, may shed light on the physiologic role of this newly discovered peptide and on intestinal adaptation to common digestive disorders.

A generalized debilitating disease in a horse was believed to be related to hypersensitivity to migrating strongyle larvae. The clinical signs included weight loss, diarrhea, and ulcers on all 4 coronary bands. The mare's condition deteriorated rapidly, so the mare was euthanatized and necropsied. The major histopathologic findings were chronic multifocal eosinophilic pancreatitis, hepatic portal fibrosis, biliary hyperplasia, and chronic ulcerative eosinophilic colitis. This case was similar to previously reported cases of chronic eosinophilic gastroenteritis in horses. Although the etiologic agent was not evident, the distribution and character of the lesions were consistent with a hypersensitivity response to migrating parasitic larvae, most probably Strongylus equinus.

In a prospective study, several parameters of small intestinal function have been assessed in 20 patients with chronic relapsing pancreatitis with and without steatorrhoea. By and large all routine parameters of small intestinal function were found to be normal. In particular, neither a previously reported high incidence of lactase deficiency, nor D-xylose malabsorption or vitamin B12 depletion was observed. However, there was a high incidence of abnormal 14C-cholylglycine breath tests (40%), suggesting the presence of mild bacterial overgrowth. Occasionally, this condition was associated with diarrhoea and steatorrhoea, thus indicating that steatorrhoea remaining after high-dosage pancreatin supplementation might sometimes be due to bacterial overgrowth.
