N/A Esophageal Varices Bleeding is one of the major causes of death among the patients with liver cirrhosis or portal hypertenison, and it represents,50% mortality each episode of bleeding. As the method for the treatment of Esophageal Varices Bleeding, supportive cares such as Balloon tamponade, infusion of vasopressin are usually practiced but the results of therapy have been found unsatisfactory. Although surgical therapy can also be expected to improve the one-year survival rate, its long-term survival rate is very low because of high incidence of morbidity. For the purpose of improving these therapeutic defects, Endoscopic Injection Sclerotherapy has been tried as a new method and its good effects have been reported recently. Endoscopic Injection Sclerotherapy is so effective on the emergency treatment of Esophageal Varices Bleeding. However, it gives rise to many debates on the improvement of long-term survival rate. To investigate long-term prognosis of Endoscopic Injection Sclerotherapy, we evaluated the survival rates and the therapeutic effects on 150 patients with Esophageal Varices Bleeding, who were treated by Endoscopic Injection Sclerotherapv and could be followed up by the Department of Internal Medicine, In-Je Medical College. The results are as follow;. 1) Rebleeding occurred in,53 cases(35.3%) among patients followed up over one month after the first Endoscopic Injection Sclerotherapy. The incidence of rebleeding was highest within 6 months, noted in 23 cases (15.3%) which were 43.3% of all rebleedings. 2) Major complications of Injection Sclerotherapy were 6 cases of aspiration pneumonia. 4 cases of esophageal ulcer, 3 cases of esophageal stenosis, and of mediastinitis.Among all 16 cases fatal complications were estimated in cases. 3)During the follow up-period, 66 cases (44.0%) were expired. 26 cases (17.3%), which were 39.4% of all mortality, of expired cases were within one month after Sclerotherapy. The causes of their deaths were of hepatic failure in 35 cases(23.3%), of hepatoma in 16 cases (10.7%). of uncontrolled bleeding in 13 cases (8.7%), and of complications in 2 cases (1.3%). 4) The one-year survival rate of the patient afteer Sclerotherapy was 70.0%, and the four-years survival rate 40.0% (8 cases of 20 cases were survived). The survival rate of those patients was concerned with Child's Classicfication and remarkeable reduction in survival rate was noted in Child's class C. As the preceeding results, it isconsidered to be obvious that Endoscopic Injection Sclerotherapy is a recommendable method for the treatment and Esophageal Varices Bleeding. However, still high frequency of rebleeding and Hospital mortality are considered as projects to be improved hereafter.

N/A A peptic ulcer is a benign ulcerative lesion in the alimentary tract developed by corrosive and digestive action of acid and pepsin in gastric juice and its cause is thought to be due to the imbalance of aggressive factors and defense mechanisms in gastric juice. But there are many controversies about the etiologic factors of peptic ulcer and further studies are needed for understanding of the pathophysiologic mechanisms. Recently it has been reported that bile and pancreatic juice could be refluxed into the upper duodenum or stomach under certain conditions, so gastric and duodenal ulcers could be induced by those digestive actions. This reflux phenomenon is supposed to be an important etiologic factor of gastric ulcer. More specifically, bile acid and lysolecithin of the refluxed duodenal contents increase back diffusion of hydrogen ions in the stomach and this back diffusion of hydrogen ions could induce acute or chronic gastritis and gastric ulcer. Moreover, it is carefully presumed that this reflux-induced acute and chronic gastritis acts as a factor of non-ulcer dyspepsia, and chronic stimulation of refluxed bile acid and lysolecithin seems likely to be an etiological factor for the development of stump cancer in gastrectomized patients. In this study, we have investigated the levels of bile acid and lysolecithin concentration in gastric juice for the evaluation of some influences of gastroduodena1 reflux on several gastroduodenal diseases. The results were as follows: 1) Bile acid concentration of gastric juice was 46.5±31.0 μmol/l in 13 normal controls, 202.2±109,2 μmol/l in 20 cases of duodenal ulcer, 329.1±101.5 μmol/1 in 28 cases of gastric ulcer 241.8±147.7 μmon/1 in 14 cases of stomach cancer and 352.1±88.7 μmol/1 in 18 cases of non-ulcer dyspepsia. 2) Lysolecithin concentration in gastric juice was 81.0±22.9 μmol/1 in 10 normal controls, 114.3±40.1 μmol/ l in 12 cases of duodenal ulcer, 170.4±43.9 μmol/1 in 10 cases of gastric ulcer, 230.3±172.0 μmol/1 in 6 cases of stomach cancer and 238.9±187.6 μmol/l in 7 cases of non-ulcer dyspepsia. 3) Average bile acid concentration in gastric juice showed a significant increase in each disease group and it was more prominent in gastric diseases including non-ulcer dyspepsia and gastric ulcer than in other groups. 4) Lysolecithin concentration in gastric juice also showed a significant increase in each disease group and it was more prominent in gastric ulcer than in duodenal ulcer. Lysolecithin concentration in the non-ulcer dyspepsia and stomach cancer groups showed a more prominent increase than the control group and duodenal ulcer group but we could not apprehend the clinical significance because the number of cases was negligible. 5) There was no specific correlation between bile acid and lysolecithin concentration of gastric juice in 20 cases of gastric and duodenal ulcers, From our findings, the constant increase of bile acid or lysolecithin concentration in gastric juice might be one of the etiologic factors in development of gastroduodenal diseases, particularly in gastric diseases. However, further study about this problem is thought to be needed.

N/A Although several classifications of esophageal varices are reported at present monent, none of them seems to be perfect in terms of clinical applicability. Some are too simple to cover the whole features of varices, or too much complicated to apply practically to clinical practices. Recent remarkable advances of endoscopy has let more precise serial observations and prognostic evaluation of varices be possible without great difficulties. Having observed 373 cases of esophageal varices from Jan. 1981 to June. 1984 at Paik Hospital, In-Je Medical College, we have tried a new classification of esophageal varices, according to not only their shape, size, numbers, colors and locations, but having particular consideration on their bleeding episodes. Endoscopic grades of esophageal varices are classified into following 4 grades, Grade I: One or two tiny tortuous, blue colored varices, less than 2 mm in diameter, being localized in lower esophagus. Grade II: Bead-like tortuosity, blue colored varices, mostly 2-4 mm in diameter being localized in lower esophagus. Grade III: Varices on the top of the varices, red colored, mostly more than 4 mm in diameter with spreading up to mid esophagus. Grade IV: Grade III varices with spreading through the entire esophagus and or down to the fundus of stomach. Bleeding tendency was most frequently observed in Grade IV varices.

N/A A clinica] analysis was made, by enzyme immunoassay, of 64 cases of coexistence of HBs antigen and HBs anti-body in the same serum with the subtype in 12 cases of them being observed. The results were as follows: 1) The overall incidence of coexistence in one period was 1.9% (64/3,395). 2) The highest occurrence rate of coexistence was found in age group of 5th decade: 14 cases (21.9%); in age group of 6th decade: 17 cases (26.6%); and the ratio of male to female was 2.4:l. 3) The diagnostic distributions were 18 cases of liver cirrhosis, 12 cases of hepatoma, 6 cases of chronic active hepatitis, 6 cases of acute viral hepatitis, 7 cases of healthy carrier, and 15 cases were suspected to be chronic hepatitis not confirmed by liver biopsy. 4) In 64 cases of coexistence we studied Hbe antigen and Hbe anti-body in 32 cases. In this study Hbe antigen positive and Hbe antibody negative was found in 18 cases (56.3%); Hbe antigen negative and Hbe antibody positive in 11 cases (34.4%); both Hbe antigen and Hbe antibody vere positive in 1 case (3.1%) and negative in 2 cases (6.2%). 5) The results of subtype were as follows: in 12 cases of HBs antigen positive only, 8 cases were of ay type and the other 4 cases of ay/ad complex type. And in 12 cases of HBs antibody positive onlv, 5 cases v:ere found to be of anti-y type. 5 cases of anti-d type, 1 case of anti-a type and 1 case of anti-y/anti-d complex type. And in 12 cases of HBs antigen and HBs antibody coexistence, ay type antigen were found in 8 cases, and antibody types of these antigen were 8 cases of anti-y type, and 1 case of anti-y/anti-d complex type. In conclusion, although the results of these studies are those of the screening test and have geographic limitation. The coexistance of HBsAg and anti-HBs is considered mostly as a form of seroconversion and rarely as a result of the superinfection with another subtype.
