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.

In order to give an overview of recent advances in general surgery, it is necessary to define: (i) what is general surgery; (ii) what is recent; and (iii) what constitutes an advance. General surgery appears to have entered an era of conservatism. This is particularly evident in the surgery of breast cancer, peptic ulceration, varicose veins, liver trauma, portal hypertension, upper gastrointestinal bleeding, and hiatal hernia. Controlled clinical trials in surgery have become popular. The following are considered to be advances: parenteral nutrition, suction drainage, control of Gram-negative sepsis, bypass surgery for pathological obesity, and a discriminatory approach to transplant surgery.

One hundred and eighty-two patients undergoing splenectomy in infancy and childhood were followed for periods of 2 to 15 years. Serious infections occurred in 11 patients (6%) with death in 6 (3.3%). In 10 patients the infection was sepsis, and in all but one patient the infection occurred within 2 years of splenectomy. Among children over 2 years of age the risk of infection was still appreciable except when the spleen was removed incidentally or for traumatic rupture. Splenectomy for thalassemia and portal hypertension resulted in an increased risk of serious infections when compared with removal of the spleen for hereditary spherocytosis, idiopathic thrombocytopenic purpura, trauma, or for technical reasons in the course of another operation. Post-splenectomy infections tended to follow a characteristic pattern. The infecting organism was predominantly pneumococcus, the course was fulminating and the mortality high.

One hundred and thirty splenectomies were performed at the University Hospital in Birmingham for hematologic disorders during a 12 year period. There were seven deaths of which four were related to sepsis in patients with malignant growths which probably impaired immune competence. Splenectomy was found to be uniformly satisfactory for hereditary hemolytic anemia, for hypersplenism complicating rheumatoid arthritis and for the rare instance of primary hypersplenism. Splenectomy was usually salutary in didopathic thrombocytopenic purpura and in antoimmune hemolytic anemia. When done for diagnosis, splenectomy was definitive in about 50 per cent of the instances. Individual patients with thrombotic thrombocyeosinophilia syndrome benefited. Splenectomy for hypoplastic or aplastic anemia in an actual circulation offered only questionable benefit and is rarely necessary for hyperplenism secondary to portal hypertension.

The efficacy and safety of using umbilical venous catheters vs. peripheral venous catheters for the delivery of parenteral nutrition was studied in 129 critically ill premature infants who were treated in a neonatal intensive care unit for the first 3 weeks of life. Infants who received parenteral nutrition by umbilical venous catheter had greater parenteral caloric intake, lower physiologic weight loss and greater weight gain during the study as compared to infants who received parenteral nutrition by peripheral vein. While the overall incidence of sepsis was comparable in both groups (19% vs 19.7%), benign and transient episodes of hyperglycemia were seen more commonly in infants receiving parenteral nutrition by umbilical catheters. None of the hyperglycemic infants, however, required insulin therapy. The incidence of other metabolic complication was comparable in both groups. At follow up, no evidence of portal hypertension was detected in any of the infants up to 66 months of age treated with umbilical venous catheters. We conclude that the use of umbilical venous catheter allows for a comparably safe and a more appropriate parenteral nutrition support than peripheral catheters in critically ill premature neonates.

Hepatolithiasis or intrahepatic stone is associated with a variety of complications of which biliary sepsis is one. Left untreated, infection results in formation of micro-abscesses, portal thrombophlebitis and fistulation into adjacent structures. With repeated infection, biliary strictures and severe destruction of liver parenchyma occur. Biliary cirrhosis, portal hypertension and bleeding varices are the terminal manifestations. Early recognition and proper treatment are essential for the prevention of severe complications and functional deterioration.

We have analyzed the indications and results of shunt operation versus orthotopic liver transplantation (OLT) in 22 patients with Budd-Chiari syndrome (BCS). The underlying cause of the syndrome was similar between the two groups and was related to myeloproliferative disorders or the use of birth control pills in 18 of 22 patients. The results of biopsies of the liver showed centrilobular congestion and necrosis in all candidates who underwent shunting and the presence of fibrosis and cirrhosis in the OLT candidates. The indications for shunts included symptoms related to portal hypertension only and well-preserved synthetic hepatic function. Ten patients were treated with 12 shunt procedures, including mesoatrial (eight patients) and side to side portacaval shunt (four patients). Significant complications after shunt procedure included fulminant (one of ten patients) and progressive (one of ten patients) hepatic failure requiring urgent OLT; one death occurred because of pulmonary sepsis. Indications for OLT were signs of end stage liver expressed by severe portal hypertension and variceal bleeding (four of 14 patients), progressive encephalopathy (seven of 14 patients) and poor synthetic function (bilirubin greater than 3 milligrams per deciliter in eight of 14 patients and albumin less than 3.0 grams per liter, or both, in ten of 14 patients). Fourteen patients were treated with 16 OLT, three patients had retransplantation for primary nonfunction graft (two of 14 patients) or chronic rejection (one of 14 patients). There were two early deaths in the group. With a follow-up period between two months to five years, 12 of 14 patients undergoing OLT are alive, fully functional and have normal liver function tests. Seven of ten patients who had shunts are alive, six are able to maintain normal activity and one has progressive end stage hepatic disease and is not a candidate for OLT. However, the hepatic function continues progressively to be abnormal. Various options are available for the treatment of the syndrome. Portosystemic decompression is effective and should be considered at the early stage of the disease, prior to the development of significant hepatic failure. However, few of the patients will continue to have slow, but progressive hepatic failure and may require OLT. The only effective treatment for end stage hepatic disease secondary to the BCS is OLT.

Pathological changes and significance of intrahepatic peribiliary glands, hitherto poorly recognized intrahepatic elements, have been evaluated in our laboratory. In this report, we surveyed necroinflammatory and cystic changes of the peribiliary glands in 1,000 consecutive autopsy livers because these two changes coexisted frequently in the same liver. The necroinflammatory change was found in 228 livers (22.8%) and the cystic change in 202 livers (20.2%), and 103 cases showed both changes in the same liver. The necroinflammatory change was frequently found in intrahepatic cholangitis and extrahepatic biliary obstruction with bacterial infection, suggesting that biliary bacterial inflammation extends into these peribilary glands. This change was also frequent in systemic infection or septicemia without biliary bacterial infection, implying that the peribiliary glands were also damaged in such conditions without direct infection. The cystic change was frequent in livers with portal hypertension or obstruction, adult polycystic disease and necroinflammation of the glands, suggesting that the cystic change of the glands could occur as the result of the disturbance of intrahepatic circulation or as the result of inflammatory destruction of the glandular conduits. Some of peribiliary cysts may be of congenital origin. Dysfunction related to these pathological changes in the glands may diminish seromucous secretion and cause alterations in hepatic bile composition. The cystic change of the glands may retard bile flow by compressing bile duct lumina.

One way to nutritionally support patients who cannot swallow is to administer formula directly into the stomach. Placing a gastrostomy tube percutaneously using endoscopy avoids the risks of general anesthesia and wound healing that accompany surgical gastrostomy. Although certain conditions (eg, sepsis, coagulation disorder, portal hypertension) are contraindications to the procedure, it can be done in patients who have had previous abdominal surgery and in those with severe illness. A commercially available feeding formula is used. The type chosen and the frequency of administration are based on the patient's specific needs. With regular medical monitoring and daily care of the gastrostomy site, appropriately selected patients may be safely maintained with enteral feeding for months. An advantage of the percutaneously inserted tube is that it is easily removed when the patient regains the ability to eat, and the fistula heals rapidly.

The authors report the cases of five children in whom kala-azar was undiagnosed at first instance. In these cases, the diagnosis was misled because of incomplete features (lack of fever, splenomegaly or hypergammaglobulinemia) an associated disease (hydatic cyst of the liver) or a complication dominating the clinical pattern (septicemia, staphylococcus respiratory infection). In one case, the patient was explored in order to diagnose portal hypertension.
