The authors report the case of a patient suffering from ulcerative colitis, who had several episodes of digestive hemorrhage due to portal hypertension. Portal hypertension was secondary to chronic portal vein thrombosis. This diagnosis was made on the venous phase of celiac and mesenteric angiography. The authors review the published cases of ulcerative colitis with portal vein thrombosis and discuss the possible etiologic factors: hypercoagulability, thrombocytosis, and intraabdominal sepsis.

A young male with Buerger's disease who had previously required a left leg amputation died in renal failure and sepsis. Postmortem examination revealed an obliterative lesion of the celiac artery, which resulted in hepatic, splenic, and pancreatic infarctions. Celiac artery involvement represents an unusual manifestation of thromboangiitis obliterans.

Solitary hepatic abscess has a favorable prognosis in contrast with multiple abscesses which generally are fatal. As compared with the classical cause of appendicitis, at present, abscesses are frequently related to biliary tract and diverticular disease. Occult or temporally remote processes are responsibile for many solitary abscesses. Lethality of multiple abscesses is related to fulminant hepatic and source sepsis, atypical syndromes, late diagnosis and difficult, complex treatment. Causative organisms are predominantly gram-negative and increasingly anaerobic, requiring special bacteriology for isolation. Various laboratory data are useful in diagnosis and prognosis, but liver scans and celiac angiography are critical procedures. Treatment aimed at lowering the mortality of multiple liver abscesses includes early diagnosis, surgical exploration and abscess drainage, direct bacterial identification emphasizing anaerobic techniques, intense specific antibiotic therapy and identification and definitive therapy of the seeding focus with special attention being given to the biliary tract.

Severe splenomegaly and anemia developed in a 5-year-old girl with diffuse lymphangiomatosis of the upper part of the body. Radioisotope scanning and celiac angiography demonstrated lymphangiomatosis of the spleen, a rare but diagnosable condition. Intractable infection in areas of ulcerated skin led to her death from overwhelming sepsis.

We present two cases of ruptured mycotic aneurysms infected with Staphylococcus aureus. Each patient had hemoptysis and in each case there was hemothorax caused by a ruptured mycotic aneurysm of the celiac artery. In case 1, the pathogenesis was transient Staphylococcus aureus septicemia infecting an atherosclerotic plaque with subsequent aneurysm formation and rupture. In case 2, the septicemia arose from an infected knee. The presentation of a celiac artery aneurysm as hemoptysis and as the cause of hemothorax is rare.

Orthotopic hepatic transplantation has become a well-established treatment modality for end-stage liver disease, and research in this field is constantly evolving. Of the 34 canine liver transplants performed in this study, 17 (50%) survived more than 3 days (mean survival time 15 days). Causes of perioperative death included hemorrhage (4), anesthetic complications (3), systemic anaphylaxis (3), portal vein thrombosis (3), hepatic venous outflow block (2), and hepatic artery thrombosis (2). Gentle handling with minimal dissection of the donor liver in situ resulted in a decreased incidence of hepatic venous outflow block. The incidence of biliary leak was similar irrespective of the method of biliary reconstruction, although the incidence of acute cholangitis was 56% in the cholecystoduodenostomy group compared with 0% in the choledochocholedochostomy cohort. Using celiac to common hepatic end-to-side arterial anastomosis with preservation of the gastroduodenal artery, thrombosis of the hepatic artery was encountered in four instances, an incidence similar to previously reported studies where end-to-end hepaticohepatic arterial anastomosis or donor aortic conduit was utilized. The incidence of postoperative intestinal intussusception was reduced from 40 to 0% in those who underwent transmesenteric intestinal plication following implantation of the liver. Among short-term survivors, sepsis was the most frequent noted complication (10), followed by intestinal intussusception (6), rejection (6), and gastrointestinal bleeding (1). Among recipient dogs that survived more than 3 days, rejection was the most common cause of graft loss (5), followed by biliary leak (4) and hepatic artery thrombosis (2).

Most techniques described in animal models of pancreatic transplantation use either segmental or autotransplants. We employ a technique of pancreaticoduodenal allotransplantation in the dog that closely resembles the operation used in humans. The arterial supply of the entire pancreatic graft is preserved by procuring a Carrel patch of aorta encompassing the origin of the celiac and the superior mesenteric arteries. Splenic, inferior pancreaticoduodenal, and superior pancreaticoduodenal arteries remain intact with the graft. Venous drainage is through a short segment of portal vein. A 6-cm cuff of duodenum is taken with the head of the pancreas. Engraftment proceeds by placing the allograft within the peritoneal cavity of the recipient. End-to-side vascular anastomoses are constructed to distal aorta and inferior vena cava. The duodenal cuff is anastomosed to the dome of the bladder for drainage and analysis of exocrine secretions and to provide a port of entry for cystoscopically directed needle biopsy. A total pancreatectomy is performed to induce a state of diabetes. The average operating time is 5 h. Twenty-two dogs have undergone allotransplantation using this technique. Six dogs had no complications and were sacrificed after meeting criteria of their study protocol. There were three technical failures, two arterial thromboses and one exsanguination, yielding an 86% rate of successful engraftment. Three other dogs died of intussusception and three dogs died of sepsis, one secondary to wound dehiscence and one due to inadvertent common bile duct ligation during pancreatectomy. Wound problems, four dehiscences and two superficial infections, occurred only in immunosuppressed dogs.

A case of pyogenic liver abscess following successful mesenteric artery revascularization is described in a patient with acute mesenteric ischemia. Prior to revascularization, arteriography confirmed celiac and superior mesenteric artery occlusion. Occurrence of liver abscess is explained on the basis of ischemia impairing the barrier function of the intestinal mucosa, contributing to portal bacteremia that seeds ischemic or necrotic liver. In patients with acute mesenteric ischemia, sequential sonographic examination of the liver following mesenteric revascularization is advocated for early diagnosis of liver abscess if there is clinical evidence of the sepsis.

A wide variety of disorders can result in diminished splenic function. The pathophysiology appears to be clearly defined in some instances, such as congenital asplenia and disorders of splenic vascular obstruction or congestion. In others, such as the autoimmune and GI disorders, the mechanism remains poorly defined. Further research is needed. The hyposplenia which occurs in many of these disorders has been associated with an increased risk of life-threatening, overwhelming bacterial sepsis. In other instances, this complication has not been reported. This certainly should not be interpreted to mean that it cannot occur. The risk of septicemia in hyposplenic disorders is rarely above 10 to 15%. In disorders with minimal inhibition of splenic function, the incidence of sepsis would presumably be less than the 1.5% incidence following surgical splenectomy for trauma. Considering these data, a very large number of patients would have to become asplenic before it would be likely that one would develop sepsis. Furthermore, the lack of awareness of the possibility of hyposplenia-related sepsis in many of these disorders may cause such occurrences to go unrecognized. Finally, since the risk of sepsis is probably less in hyposplenic adults as compared to children, studies on adults may underestimate the incidence of this complication in children. Many of the disorders reported to cause hyposplenia in adults have not been noted to do so in children. In instances such as celiac disease, it may take many years for the complication to manifest so that it would be unlikely for a child to manifest hyposplenia during childhood. However, in other instances, not enough children have been studied to be confident that the hyposplenia and its associated risk of sepsis are not complications that occur in children. Hyposplenia-related bacterial septicemia is a catastrophic complication. If a patient develops a disorder that is potentially associated with hyposplenia, the patient should be observed for signs of asplenia in the peripheral blood. If the technique is available, quantitation of red cell pits should be performed. If not, other studies of splenic function such as radionuclide scans should be considered, depending on the incidence of hyposplenia in that particular disorder. If evidence of asplenia develops, pneumococcal vaccine should be administered, penicillin prophylaxis should be considered, significant febrile episodes should be managed aggressively, and probably most importantly, the patient and family should be carefully educated about this complication. Most deaths from hyposplenia-related septicemia are preventable.

The patient presented with a diabetes at the age of 3 years. At the age of 5 years she got persistent diarrhoea, lost weight and showed symptoms or arthritis and pericarditis. She was found to have total villous atrophy of the jejunum, which did not respond to dietary treatment, total parental nutrition, prednisone and cyclophosphamide medication. She had high titres of antinuclear antibodies and elevated serum IgG, but antibodies to DNA and to ribonuclearprotein were negative. A low titre of antibodies to human intestinal epithelial cells was found. The patient died of overwhelming fungal sepsis. We propose that the intestinal damage is part of the autoimmune disease. Careful study of jejunal biopsy specimens is helpful in distinguishing this type of patient from patients with coeliac disease.
