Because the intestinal mucosa is most sensitive to ischemia, serum levels of mucosal enzymes, such as diamine oxidase, may be most likely to indicate intestinal ischemia. Our aim was to compare serum levels of mucosal (diamine oxidase, alkaline phosphatase) and seromuscular (creatinine phosphokinase, lactic dehydrogenase, serum glutamic oxaloacetic(More)
Background: Over 2 million patients in North America are on warfarin anticoagulation therapy for prevention of thromboembolism. Suspension of warfarin therapy is often required to prepare patients for invasive procedures or surgeries. To protect these patients against thromboembolism while they are off warfarin, shorter-acting parenteral agents such as(More)
Food is an important stimulus for the growth of gastrointestinal mucosa. Gut structure is influenced by the route of nutrient administration, dietary composition and the availability of specific nutrients. The alterations in intestinal structure and function that occur when enteral nutrition is withheld suggests that the ingestion of food results in(More)
We reviewed our experience with 90 patients with pancreatic pseudocysts to determine if the cause of pancreatitis influenced the patients' outcome. Acute pancreatitis (AP) occurred in 57 (63%) patients due to alcoholic (n = 15), postoperative (n = 14), biliary (n = 12), and other etiologies (n = 16). Thirty-three (37%) patients had chronic pancreatitis (CP)(More)
The outcome of 68 patients with asymptomatic cholelithiasis undergoing laparotomy for other conditions was reviewed to determine those most likely to become symptomatic postoperatively. Thirty-seven patients (54%) became symptomatic postoperatively. Eight patients (22%) required cholecystectomy within 30 days of operation or within the same hospitalization.(More)
Mucosal diamine oxidase (DAO) decreases during intestinal ischemia and may be a useful marker of intestinal ischemic injury. Tissue DAO activity and histologic changes were studied in intestinal segments taken from the midpoint of the small intestine before and 2, 4, and 24 hr after manipulation of the intestinal blood supply in 24 mongrel dogs. Intestinal(More)
Pregnant FDA-strain Osborne-Mendel rats were administered repeated doses of caffeine by oral intubation (gavage) and by administration in the drinking water (ad libitum sipping). When [1-methyl-14C]caffeine was administered at a dosage of 80 mg per kg per day by ad libitum sipping on days 12 to 15 of gestation, the amounts of radioactivity in blood were(More)
Our experience with 52 patients who had postoperative pancreatitis develop during a nine year period was reviewed to characterize this group, to determine the incidence of complications and to identify variables predictive of complications. Biliary tract procedures (n = 10), colectomy (n = 9) and intestinal resection (n = 9) were the most frequently(More)
The incidence and significance of pancreas-related complications (pseudocysts, abscesses, and fistulas) were evaluated in 100 patients with acute pancreatitis. Alcoholic (40 percent), biliary (20 percent), and postoperative (15 percent) pancreatitis were seen most frequently. Eighteen patients had severe pancreatitis (3 or more Ranson's criteria). The(More)
Several factors might affect the growth of neomucosa after serosal patching of small intestinal defects. Often only short segments of small intestine can be patched because of limited serosal surface and anatomic factors. The purpose of this study was to determine the influence of patch size on neomucosal growth. Twenty male New Zealand white rabbits(More)
