Primary small bowel malignant tumors.
We reviewed 69 patients who underwent surgery for primary malignant tumors of the small bowel over a 15-year period. Patients with periampullary lesions were excluded, as were those with known adenocarcinomas in other sites. There were 46 males (67%) and 23 females (33%) with an average age at presentation of 52.6 years (range 4-92). Of the 69 patients, four (6%) were asymptomatic. The mean duration of symptoms before diagnosis, in the remaining 65 symptomatic patients, was 3.6 months (range 1 day 1.2 years). The most frequent symptom was abdominal pain (83%), followed by nausea and/or vomiting (54%), and weight loss (43%). Abdominal mass was the most common finding on physical examination (29%), followed by abdominal distension (24%) and abdominal guarding and rigidity (14%). Laboratory examinations were normal in 26 patients (40%). Radiographic study of the duodenum and small bowel was abnormal in 87%. The diagnosis was suspected preoperatively in 51%. Lymphoma was the most common tumor (42%), followed by adenocarcinoma (38%), carcinoid (10%) and leyomiosarcomas (10%). In 41% the neoplasm was located in the jejunum, in 33% in the ileum, in 22% in the duodenum and in 4% multiple sites were found. Lymph node metastases were found in 45% and vascular invasion was found in 19%. Of the 65 symptomatic patients 43% presented as surgical emergencies, the rest had elective surgery. 61% had a curative resection, the rest were palliative or a bypass. The operative mortality rate was 10% and the morbidity rate was 24%. Ten patients underwent emergency surgery, developed a complication, giving a morbidity rate of 32% in this group. The 5-year overall survival was 43.25%. The 5-year survival for carcinoid tumors was 60% while the 5-year survival for small bowel malignant lymphoma and adenocarcinoma was 40 and 34.28% respectively.

Fulminant hepatic failure after Lepiota mushroom poisoning.
We present ten patients who suffered from a cyclopeptide syndrome from two different foci, one caused by Lepiota helveola (seven cases) and the other by Lepiota brunneoincarnata (three cases). Of the ten victims, five recovered completely after the intestinal stage and the other five developed a phase of visceral involvement with alterations of liver function. In two patients, hepatic function became normal after the 7th day after ingestion. Three patients developed fulminant hepatitis and two of these died of adult respiratory distress syndrome. The fulminant hepatitis patient who later improved developed active chronic hepatitis 1 year later. Finally, five patients developed mixed polyneuropathy. In this paper the indications for orthotopic liver transplant (OLTx) are discussed and the development of late complications such as active chronic hepatitis and mixed polyneuropathy are considered.

Long-term results of choledochoduodenostomy in the treatment of choledocholithiasis: assessment of 225 cases.
During a 10-year period 2610 patients were operated on for biliary lithiasis; in 225 (8.6 per cent) cases the operation concluded with a choledochoduodenostomy. The commonest preoperative diagnosis (62.2 per cent) in these 225 patients was choledocholithiasis; 30 patients had previously had a cholecystectomy. After choledochoduodenostomy, 4.0 per cent of patients had an intra-abdominal complication; six patients developed an intra-abdominal abscess and three developed an external biliary fistula. Four patients (1.8 per cent) died, three from pulmonary complications and one from a biliary fistula. After a mean follow-up period of 4.6 years, 71.5 per cent of patients were asymptomatic. The remainder suffered from dyspepsia (15.1 per cent), colicky pain (8.7 per cent) or episodes of cholangitis (4.7 per cent). Endoscopy in the symptomatic patients allowed the following conclusions: (a) no patient with dyspepsia had a problem at the anastomosis; (b) 27 per cent of those with colic had anastomotic stenosis or the sump syndrome; and (c) all patients with cholangitis had anastomotic stenosis and residual calculi.

Traumatic avulsion of the intrapancreatic common bile duct: case report.
Injuries of the extra hepatic biliary tree following blunt trauma to the abdomen are rare. We present a case of avulsion of the intrapancreatic common bile duct. Very often the lesion is not identifiable until the signs of jaundice and biliary ascites occur. Intraoperative cholangiography is mandatory for the diagnosis, but the noninvasive magnetic resonance cholangiopancreatography could readily depict the injury of the extrahepatic bile duct preoperatively. When the diagnosis is late the corner stone of treatment is biliary diversion and definitive repair after complete resolution of sepsis with a choledochojejunostomy.
