Immediate endoscopic injection therapy of bleeding oesophageal varices: a prospective comparative evaluation of injecting materials in Egyptian patients with portal hypertension.
The present study was conducted to compare usual sclerosants: polidocanol 1%, ethanolamine oleate 5% and the tissue adhesive: cyanoacrylate in the control of oesophageal variceal bleeding in Egyptian patients with portal hypertension in a prospective comparative trial. Sixty patients with portal hypertension due to schistosomal hepatic fibrosis and/or posthepatitic liver cirrhosis who had presented with acute oesophageal variceal bleeding were enrolled. Patients received balloon tamponade prior to injection were excluded. Resuscitation had been done before or during emergency endoscopy. Emergency endoscopy was conducted within 2 hours from the onset of hematemesis. Patients were immediately randomized during emergency endoscopy to receive polidocanol 1%, ethanolamine oleate 5% or tissue adhesive. Variceal rebleeding was managed by reinjection. The three groups were comparable for age, sex, etiology of portal hypertension, Child-Pugh class and findings at emergency endoscopy. No active bleeding was observed at the end of all injection sessions. Rebleeding had been occurred within the first 24 hours in 2 (10%) patients in polidocanol group and 3 (15%) patients in ethanolamine group (P > 0.05). Reinjection did control rebleeding in 2 (10%) patients in ethanolamine group with a total success rate of 95%. Exsanguinating rebleeding occurred in 2 (10%) patients in polidocanol group and one (5%) patient in ethanolamine group (P > 0.05). Postinjection large ulcers were diagnosed either in polidocanol (15%) or ethanolamine (10%) groups (P > 0.05). Other complications were minor and showed no significant differences between the three groups. In coclusion, polidocanol, ethanolamine and cyanoacrylate are equally safe and effective. For immediate endoscopic injection therapy an experienced team must be available.
Endoscopic control of gastric variceal bleeding with butyl cyanoacrylate in patients with schistosomiasis.
This trial represents the Egyptian experience in cyanoacrylate injection for hemostasis of bleeding gastric varices. One hundred patients with portal hypertension due to schistosomal hepatic fibrosis and/or posthepatitic liver cirrhosis were included. All patients presented with bleeding from gastric varices either fundal (80 patients) or inferior extension of esophageal varices (20 patients) were enrolled. Injection therapy was administered as the first active measure. No tamponade or drugs were used. Cyanoacrylate was mixed with lipid and injected through a hand-made probe. A mean of 3 (range 1-9) ampoules of cyanoacrylate were used per injection session. Bleeding stopped at the end of all sessions. Ten patients (12.5%) with fundal varices had rebleeding during the first 24 hours. Reinjection could control bleeding in 6 patients with a total success rate of 95%. Four patients were managed surgically. Fatal pulmonary embolism developed in one patient (1.25%) with fundal varix. Five more patients (6.25%) died from bleeding-related liver failure. In conclusion, injection of cyanoacrylate is highly satisfactory in controlling bleeding from both types of gastric varices.
Alpha feto-protein and albumin in ascitic fluid in hepatocellular carcinoma patients.
Alpha-feto-protein (AFP) is the most popular tumor marker for hepatocellular carcinoma (HCC). It is used in diagnosis and follow up of cases by estimating its rise in the serum. The aim of this work is to study the value of estimating AFP in ascitic fluid of HCC patients with ascites. This work is a case control study on 32 patients, including 22 cases with ascites and HCC and 10 control group with ascites due to liver cirrhosis without HCC. The level of AFP was estimated in serum and in ascitic fluid by Radio-immuno assay RIA. The serum ascites albumin gradient (SAAG) was assessed by measuring albumin in all samples using bromocresole green dye binding. Guided aspiration liver biopsy and ascitic fluid cytology was done, stained with H & E. It was found that, AFP level in serum was elevated in 72.7% of HCC patients, and in ascitic fluid was elevated 63.6% HCC patients. Also, there was a highly significant, direct positive correlation between elevation of AFP in serum and in ascitic fluid (r = 0.778). No elevation of AFP in serum and in ascitic fluid was detected in control group. Ascitic fluid cytology showed malignant cells in one case only. SAAG was significantly lower in the HCC group 0.83 gm/dl than the control group 2.43 gm/dl (p-value < 0.001). Elevation of AFP in ascitic fluid is of high importance in evaluation of HCC, and is as significant as serum and runs parallel to it. Estimation of AFP in ascitic fluid is much more significant in evaluation of HCC cases than ascitic fluid cytology.
Helicobacter pylori among Egyptian patients with chronic liver diseases. A comparative study.
The prevalence of Helicobacter pylori in Egyptian patients with different stages of liver diseases was compared to those with normal liver status. Eighty patients subjected to upper gastrointestinal endoscopy were enrolled. They were divided according to their liver status into two groups; the first patients with liver cirrhosis and the second who had no liver affection. Gall bladder diseases were excluded by abdominal ultrasound examinations. Endoscopic antral mucosal biopsies were used for H. pylori screening by both culture and urease test, and for histopathological examinations. Both groups were matched as regards age, sex, and socioeconomic conditions. Culture was positive in 42.2% and 40.7% of patients in both groups respectively (P > 0.05). Urease test showed positive results in 58% and 76.6% in both groups respectively (P > 0.05). Helicobacter pylori prevalence showed no significant differences between both studied groups as regards age, sex, or type of gastric lesions. Furthermore, liver status in patients with chronic liver diseases does not play a role in distribution of infection. The study shows the high prevalence of H. pylori among Egyptians and the absence of a relation between H. pylori and chronic liver diseases.
