Hydranencephaly is congenital absence of the cerebral hemispheres which are replaced by a large fluid-filled cavity. The brain stem and basal ganglia are well formed and rudiments of frontal k occipital cortex may be present. We experienced a case of hydranencephaly caused by both internal carotid artery stenosis. We diagnosed it through the brain CT sonogram and doppler sonogram. A brief review of the related literatures was made.

BACKGROUND/AIMS: Colonoscopy is less effective at screening for colorectal cancer in the right side of the colon. Retroflexion during colonoscopy is expected to improve the detection rate of colorectal adenomas. The aim of the present study was to evaluate the usefulness of retroflexion in the right-sided colon. METHODS: From April to November 2013, a total of 398 patients were enrolled in this study. For each patient, a cap-assisted colonoscopic examination was performed. After cecal intubation, a forward view examination from the cecum up to the hepatic flexure was performed and all identified polyps were removed. The colonoscope was reinserted to the cecum, and a careful second forward view examination of the cecum to the hepatic flexure was performed, with removal of additionally identified polyps. The colonoscope was then reinserted to the cecum and retroflexed; a third colonoscopic examination was then performed to the hepatic flexure in retroflexion with removal of additional polyps. Total polyp numbers and characteristics were compared between the two forward view examinations and the retroflexion examination. RESULTS: A successful retroflexion was performed in 90.2% of patients. A total of 213 polyps and 143 adenomas were detected in the right-sided colon using the routine method of examining the right colon twice in forward view. An additional 35 polyps and 24 adenomas were detected on retroflexion. Of these 35 polyps, 27 (77.1%) were small-sized polyps (< or =5 mm) and 24 (71.4%) were adenomas. Finding additional adenomas using the retroflexion technique was associated with older age. CONCLUSIONS: Colonoscopic retroflexion is helpful in the detection of cecum and ascending colon adenomas, especially small-sized adenomas (< or =5 mm). It is particularly useful in older patients.

3.Changes in the Eradication Rate of Conventional Triple Therapy for Helicobacter pylori Infection in Korea.
The Korean Journal of Gastroenterology 2014;63(3):141-145
Although, the prevalence of Helicobacter pylori infection in Korea has declined owing to the eradication therapy, recent seroprevalence of H. pylori infection is still reported to be as high as 54.4%. Until now, "standard regimen" for eradication of H. pylori has been conventional triple therapy consisting of proton pump inhibitor, amoxicillin, and clarithromycin. However, with the increase in antibiotic resistance, especially against clarithromycin, the eradication rate of conventional triple therapy has steadily declined during the past 13 years in Korea. Present eradication rate of standard triple therapy is reported to be less than 80%, which is the Maginot line of efficacy for the currently available regimen. Therefore, new first line eradication regimen is needed to enhance the eradication rate of H. pylori infection.

4.Proton Pump Inhibitors with Clopidogrel: Is There Benefit or Harm?.
Korean Journal of Medicine 2011;80(4):405-407
The treatment of acute coronary syndromes involves a combination of antiplatelet therapies. Proton pump inhibitors (PPIs) are often recommended for prophylaxis of gastrointestinal bleeding. Recent studies have shown that the cardiovascular harmful effects of the combination therapy with these two drugs cause serious results in patients with acute coronary syndrome. However, the data on this subject, especially on the clinical outcomes, are conflicting. Based on the available data, the decision to prescribe a PPI to a patient on clopidogrel should be done after evaluation of the cardiovascular risk and the gastrointestinal benefit. Further prospective randomized trials are needed to jump to the conclusions.

5.Endometrial Carcinoma Occuring from Polycystic Ovary Disease: A Case Report.
Journal of the Korean Radiological Society 1996;35(6):961-964
Endometrial carcinoma usually occurs in postmenopausal women ; less than 5% occurs in women under the age of40. Up to one quarter of endometrial carcinoma patients below this age have PCO(polycystic ovary disease, Stein-Leventhal syndrome). The increased incidence of endometrial carcinoma in patients with PCO is related to chronic estrogenic stimulation. We report MR imaging in one case of endometrial carcinoma occuring in a 23 yearold woman with PCO and had complained of hypermenorrhea for about three years. On T2-weighted MR image the endometrial cavity was seen to be distended with protruded endometrial masses of intermediate signal intensity, and the junctional zone was disrupted beneath the masses. Both ovaries were best seen on T2-weighted MR imagingand showed multiple small peripheral cysts and low signal-intensity central stroma.

We have experienced a case of pericardial tuberculoma, a very rare disease, with massive pericardial effusion in a 63-year-old veteran. He wdimensional echocardiography. Computed tomographic scans confirmed the presence of a pericardial mass and clinically unsuspected "lung mass". The presence of the lung mass led us a diagnostic and therapeutic dilemma. Surgery confirmed the pericardial mass which revealed tuberculosis by patholohy and loculated pleural effusion at the major fissure, so-called "phantom tumor", not a lung mass.

8.Endoscopic Treatment of a Twisted Small Bowel Obstruction after Laparoscopic Proximal Gastrectomy with Double Tract Reconstruction
The Korean Journal of Gastroenterology 2020;75(5):296-299
This paper reports a case of a twisted small bowel obstruction in a 74-year-old man that occurred after a double tract reconstruction (DTR) in a laparoscopic proximal gastrectomy (PG) for early gastric cancer. The patient had inadequate oral intake and reflux symptoms for 10 days after discharge. Imaging analysis revealed a narrowed small bowel with twists between the esophagojejunostomy and gastrojejunostomy sites. A fully covered stent was placed in the narrowed small bowel for 2 weeks. The patient was then discharged after stent removal without any dietary problems. The authors’ experience shows that twisted small bowel after a DTR in PG can be treated by endoscopy.
9.Endoscopic Diagnosis and Classification of Atrophic Gastritis and Intestinal Metaplasia
The Korean Journal of Helicobacter and Upper Gastrointestinal Research 2020;20(2):91-95
Gastritis is the term used to describe the inflammatory condition of the stomach. However, the ambiguous application of this term in clinical practice, such as in endoscopic or histological diagnosis, makes its diagnosis and treatment unclear. Atrophic gastritis is the most common finding in screening endoscopy, especially in patients with high risk of gastric adenocarcinoma; thus, definite diagnosis of the premalignant condition is important. Several classification systems and associated terminologies have been used to define the inflammatory condition of the stomach. However, many of them are based on histological findings, and their clinical application is limited in endoscopic diagnosis. Recently, with the advancement of endoscopic imaging techniques such as narrow-band imaging, atrophy and intestinal metaplasia can now be defined more precisely. Currently, many attempts have been made to classify the condition of the stomach on the basis of endoscopic findings, focusing on the risk of gastric adenocarcinoma and the presence of Helicobacter pylori.

In evaluating the esophago-gastric junction, many difficulties are well known in a single contrast study, andit may often be resolved with double contrast technique. By double contrast technique, the special en face viewfor the esophago-gastric junction was obtained in 298 cases at Inje Medical College Paik Hospital from Jan. 1981 to June 1981. Five basic patterns were recognized and classifed from type I to V. Their incidences were obtained.-type I ; 18%, type II; 50%, type III; 23% type IV ; 7%, type V; 2%. The most common position of patients is left lateral, and zero degree is the most common at elevation of fluoroscopic table. Type III is the most common typeof the esophage-gastric junction in inspiration, and type I expiration. Any significant deviations from thesenormal geometry of the esophago-gastric junction as displayed by double contrast study, indicate an abnormality.More special attentions are required to evaluate a minute pathologic condition of the esophago-gastric junction.
