A 66-year-old man was admitted because of right lower abdominal pain and was operated on for acute appendicitis on March 12, 1983. It was found that his appendix was not inflamed, but a bleeding tumor was encountered in the posterior segment of the liver. Bleeding was controlled by suturing the liver above the tumor. Postoperative celiac angiography revealed many daughter tumors scattered in, but restricted to, the right lobe of the liver. The patient was treated by transcatheter arterial embolization combined with transcatheter arterial infusion of lipiodol and Adriamycin on April 25. Subsequently, a curative operation (right hemihepatectomy) was performed on May 24. The patient is still alive without recurrence 6 months after the resection. In case of ruptured hepatocellular carcinoma, it appears to be better to perform a two-stage operation with careful estimation of functional reserve of the liver, and to conduct transcatheter arterial embolization between operations to prevent the growth of the tumor during that period.

We are reporting a rare case of peritoneal implanted hepatocellular carcinoma with rupture after transarterial chemoembolization mimicking acute appendicitis. A 45-year-old male patient presented with fever and manifestations of acute appendicitis. He received transarterial chemoembolization for hepatocellular carcinoma two months before. Emergent exploratory laparotomy revealed a normal appendix, a ruptured nodule located at the serosal surface of the terminal ileum with hemoperitoneum, and ruptured hepatocellular carcinoma at the junction of segments 4 and 8 of the liver. There was no peritoneal carcinomatosis, direct invasion to the surrounding tissue, or lymph node involvement. Postoperative course was uneventful. Histopathological examination of the resected nodule revealed metastatic hepatocellular carcinoma.

Metastasis to the appendix is extremely rare. Moreover, metastasis from a hepatocellular carcinoma (HCC) has not been reported in the English language literature. We report a case of metastasis to the appendix from a HCC in a 50-year-old man who presented with pain in the right lower quadrant of the abdomen, representing acute appendicitis. On CT, a hypervascular mass occupying the lumen of the appendix with distension of the appendiceal tip and surrounding peritoneal seeding of the HCC were observed. This is the first report of CT findings of metastasis to the appendix from a HCC.

To determine the relative frequencies of gastrointestinal diseases (GI) in patients admitted to Samtah General Hospital, Gizan, the records of 2,442 adults admitted to the medical and surgical services for gastrointestinal diseases during the period 1413 to 1416 were analyzed retrospectively. 1,028 patients had acute appendicitis. The remaining 1,414 patients were admitted for various other GI diseases. In these 1,414 patients the commonest diseases were gastrointestinal infections (36.4%), peptic ulcer disease (19%), gall bladder disease (18.5%), viral hepatitis and its sequelae (20.7%). Despite the high prevalence of cholelithiasis, acute pancreatitis was uncommon (0.1 %). Inflammatory bowel disease was rare. There was no gender - related difference in the prevalence of gastrointestinal infections, peptic ulcer disease and carcinoma of the stomach. Males were significantly more afflicted than females with viral hepatitis (p< 0.0001), cirrhosis of the liver (p< 0.0001), hepatocellular carcinoma (p< 0.0005), variceal bleeding (p< 0.0005), and peptic ulcer bleeding (p< 0.005). As a large proportion of our patients had preventable diseases, it is expected that immunization and other public health measures will reduce the frequency of these diseases in the future.

The Helicobacter genus includes Gram negative bacteria which were originally considered to belong to the Campylobacter genus. They have been classified in a separate genus since 1989 because they have different biochemical characteristics, with more than 24 species having been identified and more still being studied.H. pylori is the best known. It has an important etiopathogenic role in peptic ulcer disease and gastric cancer. Enterohepatic Helicobacters (EHH) other than H. pylori colonize the bowel, biliary tree and liver of animals and human beings with pathogenic potential. The difficulties existing to correctly isolate these microorganisms limit the description of their true prevalence and of the diseases they cause. Many studies have tried to discover the different clinical implications of EHH. Diseases like chronic liver disease, autoimmune hepatitis, hepatocarcinoma, autoimmune hepatobiliary disease, biliary lithiasis, cholangiocarcinoma and gallbladder cancer, Meckel&#180;s diverticulum, acute appendicitis and inflammatory bowel disease have been related with different EHH species with different results, although their prevalence is greater than in healthy subjects. However, these data are currently not sufficient to draw definitive conclusions. Finally, the best known role of EHH in bowel disease is production of acute and chronic diarrhea pictures initially referred to as Campylobacter. H. pullorum has been identified in patients with acute gastroenteritis. The correct identification of EHH as producers of infectious gastroenteritis is found in its antibiotic susceptibility. It is generally macrolide-susceptible and quinolone-resistant.
