1.A Study of the Upper Gastrointestinal Polyp.
Korean Journal of Gastrointestinal Endoscopy 1991;11(2):241-249
The authers had diagnosed and treated 560 upper gastrointestinal polys by endoscopy on 479 patients who had visited to the gastraeaterologic department of Hae Wha hoapital, Medical College of Korea University from January, l980 to June, l991. The results were as follows; 1) The incidence of upper gastrointestinal polyps among 52,031 endoscopy cases was 0.92% with no sexual difference and increased after 5th. decade. 2) The moet prevalent location of upper gastrointestinal polypes was stomach(90.0%), among which antrum occupied 52.9%. 3) The main symptoms of patients with upper gastrointestinal polyp were epigastric pain(77.7%), indigestion(57.0%) and acid belching(26.5%). 4) Histopathologic examination of 504 polyps in stomach revealed that 411(81.5%) were hyperplastic polyp and 80(15.9%) were adenomatous polyp. In duodenum, 35(68.6%) polyps were hyperplastic and 7(l3.7%) were adenomatous. All of 5 esophageal polyps were hyperplastic.

2.Endoscopic Removal of Toothbrush.
Korean Journal of Gastrointestinal Endoscopy 1983;3(1):85-88
With the improvement of the instrument and technic, the gastrofiberoscope has been used not only in diagnostic purpose but in therapeutic purpose. One purpose of the therapeutic methods is to remove the gastric foreign bodies. So many type and shape of forceps and baakets have been usad. for the same purpose. ifn these easea, we uaed biopsy farcep and snare to remove swallowed toothbrushes, three casea in the stomaeh and one cuse in the duodenurn.

3.Clinical Observation of Simple Localized, Esophageal Ulcer.
Korean Journal of Gastrointestinal Endoscopy 1983;3(1):1-9
Incidence of simple localized esophageal ulcer has been infrequent, but recently, clinical report of the disease has increased with remarkable improvement of diagnostic instrument and handling of endoscopy. Nine patients of simple localized esophageal ulcer with abrupt onset of symptoms and rapidhealing process were clinically studied and observed with the other literatures on the basis af age, sex, site, symptoms, causes, endoscopic findings, microscopic findings, and healing pracess. The results were followed. 1) The eiophageal ulcer revealed variable size and shape and generally localized middle third of esophagus. 2) History of therapeutic drug medication auch as capaule or/and tablet was noted mostly. 3) The symptoms were disappeared with general measures and ulcer lesions were comyletely healed without scar or stricture rapidly.

4.The Effect of Histoacryl(R) for Gastric Variceal Bleeding Which Failed by Ethanolamine Oleate Injection Sclerotherapy.
Korean Journal of Gastrointestinal Endoscopy 1995;15(1):27-32
Treatment modalities of gastric variceal bleeding are endoscopic injection sclerotherapy, endoscopic variceal ligation, combined above two method, operation, TIPS, and percutaneous transhepatic embolization. Recently, Histoacryl was introduced as a new sclerosant of acute variceal bleeding failed by others. So, we studied 18 cases of acute gastric variceal bleeding uncontrolled by EIS using Ethanolamine oleate. Intravariceal injection of Histoacryl is considered as a safe and effective method for hemostasis of intractable acute gastric variceal bleeding uncontrolled by other sclerosants. But, it is important that endoscopist should be in harmony with assistant at injection of Histoacryl. And its shooting speed should be fast because of clogging within the catheter. It is necessary to do long term study for evaluation of eradication effect in acute gastric variceal bleeding.

Despite significant advances in the diagnosis and treatment of various malignancies, the management of esophageal cancer remains one of the least responsive malignancies, Unfortunately complete excision of the tumor is impossible, because expandable anatomic structures are involved early when the diagnosis is made.

Korean Journal of Gastrointestinal Endoscopy 1993;13(3):567-572
The usefulness of microscopic examination of pure bile directly collected from the biliary tract during endoscopic retrograde cholangiography and without hormonal stimulation was evaluated in 86 patients. Cholesterol monohydrate crystal and/or calcium bilirubinate granule were observed in the bile of 64% of GB stones, 88% of CBD stones and l00% of IHD stones. But only 4% of non stone control group were positive crystals examinations. According to this results, microscopic examinations:of bile samples collected during endoscopic retrograde cholangiography exhibited a sensitivity and a specificity for cholelithiasis recognition of 82.3% and 95.8%, respectively, with a positive and negative predictive value of 98.1% and 67.6%, respectively. We conclude that microscopic bile examinations of bile samples collected during ERC is useful to investigate in patients with suspected cholelithiasis.

To investigate the diagnostic accuracy of ERCP in pancreatobiliary disease, the authors analysed the 1,244 cases of ERCP. The success rate of ERCP was 91.5%. The diagnostic accuracy of ERCP was 93.6% and complications occurred in 2.1%. Complications included pancreatitis,cholangitis and drug reactions. Among the biliary tract disease diagnosed, by ERCP, biliary tract stone was the most common finding. Compared with operative diagnosis of biliary tract stones,the sensitivity of ERCP diagnosis was 92.7% while that of sonographic diagnosis was 81.4%. The specificity of ERCP diagnosis was 94.4% while that of sonagraphic diagnosis was 80.9%. ln the diagnosis of common bile duct stones, ERCP was more accurrate than sonographic diagnosis. The results show that ERCP was a safe and effective diagnostic tool in the assessment of pancreatobiliary tract disease.
