Published online November 30, 1995

Abstract PDF: Endoscopic Variceal Ligation(EVL) was developed as an alternative to endoscopic injection sclerotherapy(EIS) for decreasing of complication rate. This new technique involves placement of small elastic O-rings around the variceal channels in the distal esophagus. To evaluate the efficacy of EVL for treatment of the acute bleeding esophagea1 varices and the efficacy of prophylactic EVL, we compared EVL in 88 patients who had recently bled from esophageal varices(Group 1) and prophylactic EVL in 45 patients with large size(Grade 2 or 3 or 4) and red color sign on endoscopic finding who had not previously had upper gastrointestinal bleeding(Group 2). Also, we compared prophylactic EVL group(Group 2) and control group(Group 3) who did not performed EVL. At the time of treatment 28.4%(25/88) of patients had active bleeding. They were all treated acutely with EVL and repeated treatment for the long-term goal of variceal eradication. Initial hemostatic efficacy of EVL for acute bleeding varices was 92%(23/25). Varices were eradicated or reduced to Grade 1 in 68%(17/2S). Early mortality rate within 2 weeks was 8%(2/25). Among patients who had eradicated or reduced to Grade 1 varices by repeated EVL sessions, over a mean follow-up of 11 months there was no difference between Group 1 and Group 2 in recurrent rate(49.1%(27/63) vs. 46.8% (15/32)), rebleeding rate(10.9'Yo (6/55) vs. 9.3% (3/32)), rebleeding interval(average 75 days vs, 83.6 days). There was significant difference between prophylactic EVL group and con- trol group in bleeding rate(9.3%(3/~32) vs. 43.7%(14/32))~(p<0.05). Three patients(6.6%) died in prophylactic EVL group, two from ligation site bleeding of esophageal varix, one from hepatic failure. In conclsion, EVL is an effective method for treatment of acute bleeding esophageal varices with repeated sessions. Although prophylactic EVL can be used to prevent bleeding by eradication with lower initial morbidity are necessary because of EVL-related complications.(Korean J Gastrointes Endosc 16: 397~405, 1996)

Abstract PDF: Endoscopic variceal ligation(EVL) is newly developed method to manage esophageal variceal bleeding. This study asse initial control rate of active variceal bleeding, incidence of rebleeding and complications in EVL. From June in l992 to December in 1994, this study was performed on 70 patients who had visited to our medical center for melena or hematemesis by acute esophageal variceal bleeding. In all of 70 cases, eradication of esophageal varix was performed and variceal bleeding was controlled well. And first session was performed successfully with EVL. But rebleeding was occured in 12 cases(11 cases caused by esoyhageal varix and 1 case caused by esophageal ulcer) during follow-up period, so EVL therapy was performed repeatedly and 8 cases were eradicated and 4 cases were uncontrolled and died, and then 94% hemostatic effect was achieved during follow-up period. Complications of EVL therapy were mild(substernal discomfort in 12 cases, substernal pain in 4 cases, fever in 3 cases, mild dysphagia in 2 cases) and well controlled. Superficial esaphageal ulcer was shown in 18 cases by follow-up endoscopy after 1 week. These results show that EVL is a good therapeutic method to control active variceal bleeding and eradication of varix with repeat treatment. In conclusion, EVL is an effective and safe method of treatment and prevention for esophageal variceal bleeding. (Korean J Gestroiatest Endosc 16: 406-413, 1996)

Published online November 30, 1995

Abstract PDF: An esophago-tracheal fistula is a distressing and rapidly fatal complication of cancer infiltrating the mediastinum. The passage of swallowed saliva and solid or liquid food into the bronchial tree causes coughing and frequent episodes of putmonary infection and collapse. Curative resection is generally impossible due to the extent of the malignant leision and respiratory disability. In principle, peroral endoscopic intubatian provides the best available palliative therapy. Peroral intubation with a standard prosthesis fails to occlude inoperable malignant esopbago-tracheal fistulas located above the narrowed segment or when there is little or no stricture at all. To overcome these problems, the fistula is iniubated perorally with a prosthesis surrounded by a foam rubber cuff contained in silicone sheath, in which a vacuum can be created. The cuffed esophageal prosthesis can improve the quality of life in patients with malignant esophago-tracheal fistulas that do not respond to conventional intubation. We experieneed a case of the endoscopic treatment with a cuffed prosthesis for esophago-tracheal fistula without esophageal stricture in a patient with malignant lymphoma. After treatment, there were no symptoms related to the fistula and good transit of food was achieved. So we report this case with a brief review of the previous literatures.

Abstract PDF: Glycogenic acanthosis(GA) of the esophagus,is often found in routine endoscopic examination of the upper GI tract but has not drawn much attention. However, there is controversy concerning the nature, clinical significance and prevalence of this candition. An endoscopic study, performed in 1041 patients, showed that the incidence of GA was 32,9%. Its incidence was found to be significantly higher in male than in female(40.0% vs. 22.1%; p<0.0001) and frequency of high grade(II+III) GA was higher in male than in female(58.1% vs. 45.3~%; p<0.0D01). An increasing tendency was observed with respect to age(X 36~343, p~<0,0001). The frequency of GA was higher in smoker than in non-smoker(49.2% vs. 20.8%; p<0.0001). GA did not have a clear relationship with alcohol intake, dietary habit, condiments, and diet temperature. The frequency of GA was higher in the patient with reflux esophagitis than without reflux esophagitis(3.8% vs. 1.7%; p~<0.05). Therefore, age, sex and smoking appear to be risk factors of GA, as in esophageal carcinoma. (Korean J Gastroiatest Endosc 16: 423-428, 1996)

Abstract PDF: In case of submucosal tumor, adenoma and atypism, we can't frequently use the snare polypectomy for treatment of them. Adenoma and atypism are premalignant, so other therapeutic modalities are necessary for resection of them. We have perfortned endoscopic mueosectomy such as strip biopsy, and "O"ring ligation on various mucosal lesions of upper GI tract in 23 patients(11 men, l2 women) from June 1993 to December l994 . Fourteen patients wbo had adenoma were followed up endoscopically for 6 months to 24 months(mean: 14 months). The results were as follows: 23 patients(27 lesions) were enrolled in this study. Mean age was 50.3(range 32-74 years). The method of mucosectomy was strip biopsy in 19 cases(21 lesions), and "O"ring ligation in 4 cases(6 lesions). The rate of complete resection was 88.9%. If adenomas were resected incompletely, we added a laser therapy. There was no recurrence except a case in which carcinoma was detected on the other site during follow-up. No serious compication occurred such as massive bleeding or perforation. Based on the above results, the endoscopic mucosectomy is considered to be a safe and effective modality in the treatment of the flat polyps of upper GI tract and could be used for prevention of gastric cancer.

Abstract PDF: A study carried out to evaluate the bleeding control and prophylactic effect of rebleeding using emergency endoseopic sclerotherapy in patients with hleeding gastric varices. 42 patients with gastric variceal bleeding were admitted to the Yeungnam University Hospital from May, 1983 to August, 1992. Patients were randomly classified into control group, 20 patients treated with conservative management, and sclerotherapy group, 22 patients treated with emergency endoscopic sclerotherapy. The two group were analysed with age, sex, etiology of liver cirrhosis, nature of bleeding episode, hematocrit on admitting day, amount of sclercsants used, rebleeding episodes, complications, and mortality. There were no significant differences in the severity of underlying liver disease and hematocrit on admission between two groups. Blood transfusion were performed in 19 cases of control group and 21 cases in sclerotherapy group(p>0.05). The amounts of transfusion were 7. 7units in control group and 6.1 units in sclerotherapy group(p<0,05). Rebleeding were developed in 65% and 18% of the patiehts with control and sclerotherapy group, respectively(p<0.05). Chest pain and mild fever were observed after endoscopic sclerotherapy. These results suggest that the endoscopic sclerotherapy is effective method in hemostasis of bleeding gastric varices and short-term prevention of rebleeding, but mortality rate was not decreased compared to control group. Development of more effective methods to treat gastric variceal bleeding is required. (Korean J Gastrointest Endoae 16: 435-442, 1996)

Abstract PDF: Objectives
The sphincter of Oddi(SO) manometry via transpapillary route is performed usually for a period of several minutes. To investigate whether there is a considerable variation in the manometric measurements of SO over a longer period of time, we have performed long-term manometry of SO via transpapillary(n=5) as well as percutaneous(n=7) route. Methods: Transpapillary manometry of SO was carried out by conventional low- compliant continuously perfused techni~que. The location of the manometric catheter was maintained at the same level by observing the video monitor. SO manometry and the duodenal migrating motor complex(MMC) was simuitaneously measured with specially designed catheter via pereutaneous route. Results: The mean recording time was 41 minutes(range 11-72 minutes). The frequency of phasic contractions of SO varied from 0 to 12/min. Throughout the whole recording period, high-frequency contractians(over 8/min) were noted in 14.9 % of the time. In the eases of percutaneous transductal SO manometry, the periods of high-frequency contractions coincided with the phase III of duodenal MMC. The interval between the first high-frequency contractions and the second was 47 minutes. The mean duration of high-frequency contractions was 6 minutes and 4~2 seconds. There as no significant change in the amplitude, basal pressure and contraction sequence among the various periods of frequencies. Conclusions: Long-term continuous recording of SO manometry via transpapillary and percutaneous route showed that the contraction frequency of SO was not constant and tachyoddia appearde periodically. In the interpretation of tachyoddia, it is necessary to consider the period of phase III of the duodenal MMC. (Korean J Gastrointest Endosc 16; 443~448, 1996)

Abstract PDF: The safety of endoscopic retrograde cholangiopancreatography(ERCP) in patients with acute pancreatitis(AP) was confirmed in the past decade. Especially in ease of acute gallstone panereatitis, early ERCP/EST(endoscopic sphincterotomy) may reduce the incidence of complications by removing gallstone which causes acute attack of pancreatitis. To assess clinical usefulness of ERCP/EST in the setting of AP, we reviewed clinical records of 58 patients with AP who had undergone ERCP /EST during the same period of admission.

Abstract PDF: Multiple primary cancer is defined as the case of primary malignant tumors of different histologic origins each other in one person, The incidence of multiple primary cancer has been increasing recently due to more developed diagnostie procedure and long survival of cancer patients. In esophageal cancer patients, comibined prevalence of other malignancy is rela tively high. We have experienced three cases of gastric adenocarcinoma with esophageal squamous cell carcinoma and report these cases with a review of literatures, (Korean J Gastrointest Endosc l6: 459~465, 1996)

Abstract PDF: A 38-year-old man, with recurrent oral ulcers for 10 years, was admitted because of recent aggravation of odynophagia and sore throat. About 4 years earlier, he had been performed abdominal surgery for intestinal perforation. Gastrofiberscopic examination showed small round ulcers at hypiopharynx and 6cm sized longitudinal linear ulcer at mid esophagus. Biopsy specimens at mid-esophagus showed chronic inflammation. Besides oral ulcer, he had perianal ulcers and skin rashes. He was managed with steroid, colchicine and sulfasalazine under the diagnosis of esophageal involvement in Behcet's disease. After 3 months from discharge, esophagogram and gastrofiberscopic examination showed some improved appearance, but symptoms recurred for steroid tapering. He has been followed in much improved status for 8 months after discharge. (Korean J Gastrointest Endosc 16: 469~474, 1996)

Abstract PDF: The gastric adenomas could be premalignant lesions and they should be removed as possible, especially in eases with its size aver 2cm. The gastric adenomas can be removed by the various endoscopic methods. Endoscopic polypectomy has been widely used for the treatment of benign and malignant polyps with the advent of technical improvement. Polypectomy with snare and electrocautery is mainly used for pedunculated polyps, but sessile polyps pose some technical difficulties and occasionally cause serious gastrointestinal hemorrhage or perforation. We resected two cases of gastric flat adenoma using Stiegman-Goff ligator used in endoscopic variceal ligation to make flat adenoma as semipedunculated form, and also to decrease the risk of bleeding. After ligation, we successfully removed it with conventional snare polypectomy. We recognized that endoscopic mucosal resection with band ligation can be used for the removal of sessile polyps or flat adenioma with ease, safety and no bleeding.

Abstract PDF: The bleeding duodenal varices are a rare complication in patients with portal hypertension, but present a difficult diagnostic problem. If there is no bleeding esophageal, gastric fundal varices or ulcer in a patient with upper gastrointestinal bleeding and portal hypertension, the possibility of bleeding duodenal varices should be kept in mind. Thorough endoscopic examination of the entire duodenal mucosa is essential to document bleeding from duodenal varices. As an initial treatment, endoscopic sclerotherapy has had limited success in controlling active duodenal variceal bleeding. However, rebleeding rate is high, surgical treatment including shunt operation may be required for permanent control of bleeding and portal decompression. We report three cases of duodenal varices causing massive hemorrhage. All the patients had portal hypertension caused by liver cirrhosis of various etiologies and had varices in their esophagus. The second portion of the duodenum was the site of duodenal varices in all cases. The management was tailored to the condition of each patient, but only one patient among three survived.

Abstract PDF: The occurrence of the small intestinal adenocarcinoma is infrequent and the primary adenocarcinoma of the jejunum is rare. The survival of adenocarcinoma of the small bowel does not improve over the past three decades. Although symptoms appeared to be of long duration, most patients were diagnosed with advanced disease. All reports agree that these tumors are difficult to achieve good examination of the small bowel by both clinician and radiologist, so it cause a significant delay in diagnosis. The survival of these tumors appear to correlate with stage at presentation, and therefore early and aggressive diagnostic intervention seems to improve the outlook. We report a case of primary jejunal adenocarcinoma assoeiated with iron deficiency anemia with literatures review. (Korean J Gastrointeat Endosc 16: 505-508, 1996)

Abstract PDF: We presented here a rare case of intestinal Behecet's disease simulating Grohn's disease. A 20 year old female complained of recurrence of oral ulcer, genital ulcer, arthralgia, erythema nodosum, abdominal pain and diarrhea, but she had no anal ulcer or anal fistulas. The colonoscopic examanation disclosed diffuse colonie involvement with multiple longitudinal ulcers and inflammatory pseudopolyposis. In hospital, she received ileocecectomy because of distal ilea perforation. Postoperative specimen showed multiple geographic ulcer on ileocecal region, creeping mesenteric fat and thickening of cecal wall. Pathological examination showed perivasculitis, transmural inflammation, fissuring, multiple lymph follicles which are compatible with intestinal Behect's disease. There were no granuloma sugges tive of Crohn's disease. Clinically, the patient met the international criteria of Behcet's disease. Punched out ulcer in the ileocecal region and pathological findings described above confirmed the diagnosis of intestinal Behcet's disease. (Korean J Gastrointest Endosc 16: 511~516, 1996)

Published online November 30, 1995

Abstract PDF: Although the endoscopic retrograde biliary drainage(ERBD) is the preferred palliative treatment for unresectable mlignant obstructive jaundice, the failure of endaprosthesis insertion occurs in 15% of the cases. Espeeially in hilar malignancy, the failure results from the inability to pass ei~ther a guide wire or a stent due to biliary stenosis or obstruction by tumorous extension. In such caae, percutaneous transhepatic biliery drainage(PTBD) can be achieved. When the tumor extends into the hilum, isolating the right and left hepatic ducts, drainage of unilateral hepatic duct will usually provide adequate palliation. However, when patients have contralateral cholangitis or jaundice fails to resolve with unilateral biliary drainage, bilateral drainage may be necessary. Compared to ERBD, the method of prolonged external biliary drainage has unwanted disadvantages. In order to achieve internal biliary drainage in case with complete obstruction of hepatic ducts due to tumor extension, percutaneous transhepatic transtumoral biliary drainage(PTTBD) could be considered. We report a case with obstructive jaundice and cholangitis due to complete obstruction of right hepatic duct and stenosis of common hepatic duct from Klatskin tumor, which was sucessfully managed by internal biliary drainage with transtumoral biliary stenting under the guidance of computed tomography.
