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.

Plummer-Vinson syndrome is a clinical entity characterized by dysphagia, iron deficiency anemia, cheilosis, glossitis, and cervical esophageal web, especially in middle aged women. Recently, the authors experienced a case of Plummer-Vinson syndrome. A 53-year-old female was admitted due to intermittent solid food dysphagia for 18 months. She had a 2 years history of iron deficiency anemia. On admission glossitis, fissures at the angle of the mouth, spoon nails, and iron deficiency anemia were noted. Esophagogram and esophagoscopic examination revealed thin walled concentric web at upper esophagus. Esophageal web was succefully teared by endoscopic balloon dilatation with subseguant improvement of dysphagia. Skin manifestations as well as anemia were markedly improved after oral iron replacement therapy.

4.Operative Treatment of Symphyseal Disruption.
The Journal of the Korean Orthopaedic Association 2000;35(3):511-518
PURPOSE: To evaluate the efficacy of open reduction and internal fixation for disrupted symphysis pubis in unstable pelvic injuries. MATERIALS AND METHODS: Eighteen symphyseal disruptions were treated by open reduction and internal fixation from 1994 to 1998. There were 12 Tile type B and six type C injuries. In 12 patients, anterior fixation was performed whereas six patients were treated by anterior and posterior fixation. The clinical and radiological results were reviewed retrospectively at a mean of 20.4 months (range, 12 to 44 months) . RESULTS: The average symphyseal displacement improved from a preoperative value of 37.3 mm (range, 10-87 mm) to a postoperative value of 6.5 mm (range, 2-14 mm) . Leg length discrepancy which averaged 11.8 mm (range, 4-30 mm) preoperatively was decreased to 2.3 mm (range, 0-7 mm) postoperatively. Open reduction and internal fixation was associated with a higher percentage of excellent results except in osteoporotic bone. Two patients with osteoporosis had a loss of fixation. Complications were infrequent. CONCLUSION: Open reduction and internal fixation are desirable techniques for symphyseal disruption. But the supplemental wire fixation with plate would be recommended for elderly patients who show obvious signs of osteoporosis.

PURPOSE: To establish the incidence of deep vein thrombosis among Koreans after primary total hip arthroplasty and the usefulness of color doppler ultrasonography for routine noninvasive screening for deep vein thrombosis. MATERIALS AND METHODS: We performed prospective, randomized routine venography and color doppler ultrasonography before and after operation in a consecutive series of 89 primary total hip arthroplasty in which no form of prophylaxis was used. RESULTS: Of the 89 cases, eleven (12.4%) were found to have deep vein thrombosis (three proximal veins and eight distal veins) by bilateral venography. Most of the thromboses except two were asymptomatic. No patient had a symptomatic pulmonary embolism. Statistical analysis of risk factors, age, gender, weight, height, fixation method, and duration of operation time, were performed and there was no statistical difference (P>0.05). The reliability of color doppler ultrasonography for detection of deep vein thrombosis was demonstrated. CONCLUSIONS: We found insufficient evidence to recommend routine thromboprophylaxis in primary total hip arthroplasty among Koreans. The authors recommend that routine bilateral color doppler ultrasonography screening be considered after primary total hip arthroplasty for detection of deep vein thrombosis

A 52-year-old women, suffering from generalized pruritus due to intrahepatic and common hepatic duct stones, was treated with astemizole, 30mg daily. Sixty one days later, convulsions and syncope developed suddenly during hospitalization. She had no history of arrhythmia, heart disease, electrolytes imbalance, or CNS disorders. As another case, a 44-year-old man suffering from pruritus due to liver cirrhosis, was treated with astemizole, 30mg daily. Thirty two days later, palpitations and syncope also developed suddenly during hospitalization. He was diagnosed liver cirrhosis, 3 years ago and there was no history of arrhythmia, heart disease, electrolytes imbalance, or CNS disorders. Administration of astemizole was stopped immediately. The laboratory investigations revealed the normal range of serum potassium, calcium and magnesium in both cases. The ECG finding showed the prolongation of QTc interval, frequent VPCs and intermittent polymorphic drugs. On 1st and 3rd day, after discontinue of astemisole, the ECG abnormalities disappeard. It is suggested that astemizole overdose can induce prolongation of QTc interval and torsade de pointes, especially in the patient with liver disease.

PURPOSE: This study was done to determine the usefulness of serum pepsinogen (PG) levels as a screening method for gastric cancer, and to assess the relationships between serum PG and clinicopathologic factors of gastric adenocarcinoma. MATERIALS AND METHODS: Serum PG concentrations were measured in 94 subjects who were classified into (a) a control group (50 subjects) without abnormal endoscopic finding on a health checkup, or (b) a gastric cancer group (44 subjects) who had surgery at Daegu Catholic University Hospital between Nov. 2008 and May 2009. Receiver operator characteristic curves were utilized to select the most suitable test. Using different cutoff points, sensitivity and specificity were calculated. We compared preoperative serum PG levels with several clinicopathologic findings for patients with gastric adenocarcinoma. RESULTS: The Serum PG I:II ratio was the most useful as a screening test. The sensitivity and specificity of PG screening for gastric cancer were, respectively, 81.8% and 82%. The cut off point correlated with the type of intestinal cancer (Lauren classification; P=0.003), tumor stage (P=0.001), and gastric adenocarcinoma with peritumoral chronic atrophic gastritis (P=0.036). CONCLUSION: Serum PG levels were found to be a potentially useful screening test and to correlate with clinicopathologic factors in gastric cancer patients. But, in order to use serum PG found in a health checkup for gastric cancer as a clinical application a large scale study is recommended.

BACKGROUND: Laparoscopy with peritoneal carbon dioxide insufflation is a standard procedure in many gynecological departments. And more prolonged gynecological laparoscopic operations are being performed in recent years, and a steeper head-down position is required. Despite laparoscopic operations have many advantages, peritoneal insufflation of CO2 to create the pneumoperitoneum necessary for laparoscopy induces intraoperative hemodynamic changes that complicate anesthetic management of laparoscopy.The purpose of this study is to evaluate the effect of general anesthesia on hemodynamics during loparoscopic hysterectomy. METHODS: Twenty six women undergoing laparoscopic hysterectomy were randomly allocated to either a propofol (Group 1, n=13) intravenous anesthesia or a enflurane (Group 2, n=13) anesthesia with fentanyl-N2O/O2-vecuronium. Hemodynamic parameters were measured before induction (T1), 5 min after induction (T2), 5 min after head-down (T3), 5, 10, 15, 20 min after pneumoperitoneum (T4, T5, T6, T7), 5, 10 min after deflation (T8, T9). The MAP, HR, CI, SVRI, SI were measured by transthoracic electrical bioimpedence method and automated blood pressure device. RESULTS: The mean arterial pressure were increased during pneumoperitonem in both groups and heart rate were increased in Group 2. The cardic index were decreased in both groups after induction by 27.4 % in Group 1 and 25.7% in Group 2. The systemic vascular resistanace index were increased in both groups from head-down to after deflation by 68.3% in Group 1, 73.1% in Group 2 maximally. No significant changes of stroke index were observed during surgery in Group 1. CONCLUSIONS: Laproscopy with CO2 insufflation induces significant hemodynamic changes includig increases of MAP, SVR and a reduction of CI. And usual intraoperative hemodynamic monitoring; the blood pressure and heart rate give no information on the reduction in cardic output.

BACKGROUND/AIMS: Stomach cancer is the most common malignancy and one of the leading causes of cancer-related death in Korea. The early diagnosis and treatment of gastric cancer are very important because the prognosis of early gastric cancer is excellent. Gastric screening may provide an opportunity to detect asymptomatic early gastric cancer. We analyzed the characteristics of gastric cancer diagnosed with a health screening test to evaluate the usefulness of a screening program for gastric cancer. METHODS: We retrospectively reviewed the clinicopathological characteristics of 111 gastric cancer patients diagnosed using gastric endoscopy as a gastric screening test at the Health Promotion Center of Kyungpook National University Hospital from July 1997 through December 2005. RESULTS: The incidence of gastric cancer was 0.38% and the mean patient age was 58.5 years old. The proportion of early gastric cancer was 73% of all gastric cancer. In 55 cases, constituting 49.6% of all gastric cancer and 68% of early gastric cancer, the lesions were confined to the mucosa. The most common macroscopic types were type IIc in early gastric cancer and Borrmann type 3 in advanced gastric cancer. There were significant positive correlations between lymph node metastasis and both the depth of tumor invasion and size of the lesion. The 5-year survival rates are 82.7% in total gastric cancer and 97.2% in early gastric cancer. CONCLUSIONS: Gastric cancer detected during health screening has a favorable prognosis because gastric cancer confined to the mucosa predominates and early gastric cancer detected at screening has a lower incidence of metastasis to regional lymph nodes.
