To measure esophageal manometric parameters in liver cirrhosis, patients with different liver function grades were chosen. In the normal control group ( n =72) gastrointestinal disease history and symptoms, abdominal surgery and injury history were all negative. In liver cirrhosis group ( n =94) liver cirrhosis was diagnosed by clinical picture or pathology, and their liver function in Child grade was: grade A, 38 cases and 8 had ascites; grade B, 37 cases and 20 had ascites; grade C, 19 cases and 18 had ascites. Taking no motility medicines within seven days before measurement, esophageal motility parameters of these subjects were taken by a Biolab System made by Sandhill Company. The data were analyzed with SAS statistical software. The results showed that from Child grade A to C, LESP in cirrhosis group reduced, relaxation pressure increased, and relaxation percentage become lower successively; from Child grade A to C, onset peristaltic wave velocity in upper esophageal body became slower, peristaltic contraction reduced, and abnormal contraction increased; from Child grade A to C, peristaltic wave amplitude reduced in lower esophageal body, and velocity of onset peristaltic wave velocity became slower, peristaltic contraction reduced, and abnormal contraction increased. It suggests that more severe injury in liver function, more serious impact in esophageal motility. At the same time complications of portal vein hypertention such as esophageal varices and ascites behave synergetically.

Objective To analyze correlation of drug with acute drug-induced liver injury in 83 patients. Methods According to the international consensus criteria and Danan's causality assessment of a drug in the case of acute liver injury, 83 cases which had been clinically diagnosed as acute drug-induced liver injury were analyzed. Results Among the 590 inpatients of acute hepatitis, 83 (14.07%) were acute drug-induced liver injury, in whom 53 patients had liver cell damage (63.86%), 22 with cholestasis (26.5%), and 8 with mixed type (9.64%). In 34 patients, it was drug related (40.96%), undefined in 37 cases (44.57%), and unrelated in 12 cases (14.47%). Conclusion The international consensus criteria standardized the diagnosis of drug-induced liver injury and are helpful in differential diagnosis, but it needs improvement for actual implementation.

0.05). 7 cases were complicated with early rebleeding in each group, 3 cases died in the EVL group, and no patient died in the EVS group. During the follow up period of 1 year, the rate of recurrent varices was 39.4%(26/66) in the EVL group, versus 21.3% (13/61) in the EVS group, showing statistically significant difference between the two groups ( P 0.05).

0 05). No adverse reaction was seen in all patients. Our results suggest that intravenous Pantoloc is a good proton pump inhibitor in patients with duodenal ulcer combined with upper gastrointestinal bleeding, and it is similar to Losec in effectiveness and safety.

Twenty four hour esophageal pH monitoring was performed in 79 ambulatary patients suffering from reflux symptoms, in whom 40 with esophagitis and 39 without. The aim of the study was to investigate the correlation between reflux symptoms and objective occurrence of acid reflux in the patients with and without esophagitis. The results showed that the six parameters of Johnson/DeMeester score were significantly higher for esophagitis than endoscopic negative patients. The composite score were (85.85?15 10) and (26 20?9 25), respectively( P

Biopsies were randomly taken from 160 patients through endoscopy. Among them 46 patients suffered from chronic superfacial gastritis, 39 patients from chronic atrophic gastritis, 39 patients from gastric ulcer, and 36 patients from gastric cancer. Ras, p16, and p53 genes were analysed with polymerase chain reaction single strand conformation polymorphism (PCR SSCP). Helicobacter pylori (HP) was examined with RUT. Result: ① the positive rates of ras and mutant p53 in gastric cancer were significantly higher than that in gastritis and gastric ulcer( P

To evaluate the influences of sclerotherapy and band ligation on esophageal motility, EVS and EVL were measured before and after treatment respectively. After sclerotherapy, lower esophageal sphincter pressure (LESP)and residual pressure were decreased while relaxa tion was increased , relaxation duration became shorter; band ligation only influenced LESP.After EVS, the amplitude of motor waves in the sites of EVS and lower esophagus body was reduced ,and peristaltic wave duration was prolonged ,velocity of propagating contractions became faster , band ligation made the peristaltic wave duration in the sites of EVS and lower esophagus body become shorter, abnormal contractions increased. After EVS, antiacid medicine should be ased to reduced pH of gastric and raised LESP, and drugs to increase esophageal motility should be used after band ligation.

Crohn disease (CD) is a relatively infrequent disease in China. CD and intestinal tuberculosis (IT) are lack of specific clinical manifestations and are generally identified by endoscopic and histological examination. However, it is sometimes difficulty to distinguish them by endoscopy and histology. Their characteristics were investigated to offer more evidences and data for their differential diagnosis. The records of inpatients were reviewed from 1980～2001 in our hospital, all enrolled subjects were verified by endoscopy(or operation) and histology. The characteristics and key points of differential diagnosis of 28 CD cases and 14 IT cases were comparatively analyzed. The results showed that abdominal pain, mass, and hematochezia occurred more significantly in CD than in IT ﹙ P

Objective To investigate the incidence of hepatocellular carcinoma (HCC) among patients with esophageal varices bleeding previously treated with endoscopic sclerotherapy, and to evaluate the factors influencing prognosis of HCC patients.Methods The clinical data of patients (from April 1987 to May 2003) who had received sclerotherapy for esophageal varices bleeding, and also that of HCC patients who had had sclerotherapy for esophageal varices bleeding were retrospectively reviewed. The survival rates of HCC patients were evaluated with Wilcoxon-Gehan method. Sixteen risk factors for HCC were assessed by multivariate analysis (Cox model). Results A total of 934 cases were treated with sclerotherapy, among which 109 patients suffered from HCC while 825 patients did not. In 22 HCC patients with esophageal varices bleeding sclerotherapy was not given. 31 out of 825 patients (3.76%) developed HCC during the follow-up period. 17 out of 31 patients received regular follow-up while 14 cases did not. The median surviving time of 31 patients was 13 months. The survival rate of patients with HCC under regular follow-up was significantly higher than that of patients under irregular follow-up(P=0.0002); risk factors, i.e. Child-Pugh classification, age and regular or irregular follow-up, were significantly related to the prognosis of patients with HCC(P=0.039、0.029 and 0.021, respectively). Conclusion Surveillance of patients with decompensated liver cirrhosis may increase the diagnostic rate of small HCC and prolong life expectancy; sclerotherapy can lower the incidence of HCC and it may play an active role in decreasing the incidence of HCC.

Objective To investigate the indication and therapeutic effect of endoscopic pancreatic stent insertion. Meth-ods 13 procedures of endoscopic sphincter incision,2 procedures of endoscopic pancreatic stone picking,3 procedures ofendoscopic papilla adenoma or carcinoma resection. 10 procedures of endoscopic stenosis dilatation and 20 procedures ofendoscopic pancreatic stent insertion were performed on 9 cases of chronic pancreatis (in which 3 cases had pancreaticstone), 1 case of acute recurrent pancreatis.4 cases of pancreatic cancer and 3 cases of papilla adenoma or carcinoma.The duration of stent preserve was 2 weeks to 8 months, average 3. 43 months. Results Remission of abdominal pain,improvement of appetite and digestive function was found in 16 cases. 12～35 months (average 26. 17 months) of follow-up was performed on patients of pancreatitis after the stents were removed. 7 cases had no recurrence of abdominal pain,3 patients still often had upper abdominal pain. Complications:3 cases had mild elevation of serum amylase and lipase. 1case had obstructive jaundice. Conclusion Endoscopc pancreatic stent insertion and drainage is suitable for pancreaticduct obstruction caused by chronic pancreatitis or cancer. It can alleviate symptoms and has reliable therapeutic effect andgood security.
