N/AA case of retrograde intussusception of efferent limb into Braun side-to-side jejunojenunal anastomosis after gastric surgery is presented. Intussusception is an uncommon and well-recognized complication after gastric surgery. A 60-year old female was admitted to Hanyang University Hospital with a chief complaint of epigastric pain and hematemesis of 6 hours duration. Patient had a history of distal gastrectomy with gastrojejunostomy due to early gastric cancer(Stage I) 3 years ago. Emergency abdominal CT revealed jejunojejunal intussusception into Braun anastomosis. Exploration and segmental resection of jejunum with end-to-end reanastomosis were performed.

Squamous cell carcinoma of the stomach is very rare with a reported incidence of 0.09% of all resected gastric malignancies. We report here two cases of squamous carcinomas and a brief review of literatures. A 74-year old female was admitted because of epigastric pain and vomiting. Abdominal CT, UGI and endoscopic findings revealed a Borrmann type III gastric cancer on the posterior wall of the antrum with pyrolic obstruction and multiple liver metastases. Palliative distal gastrectomy with gastrojejunostomy was performed. The histopathologic diagnosis was adenosquamous cell carcinoma. She died of malnutrition and multiple organ failure 5 months after the operation. The other case was a 53-year old male admitted because of indigestion. Abdominal CT, UGI and endoscopic findings revealed a Borrmann type III gastric cancer on the greater curvature of the antrum with multiple enlargements of the perigastric lymph nodes. Distal subtotal gastrectomy with gastrojejunistomy was performed. The histopathologic finding revealed squamous cell carcinoma. He was discharged after FEC(5-FU, etoposide, cispatin) chemotherapy uneventfully.

PURPOSE: To determine whether there is a discrepancy between the medical professions perception of what patients should know and that of the patients themselves, we studied patients need to be informed about different aspects of epilepsy and compared findings with medical personnels perceptions of the issue. METHODS: Our study population consisted of 39 patients with epilepsy from the inpatient epilepsy unit, and 51patients from the outpatients clinic of the S. University Hospital between July and November 1997. However, the patients who declined to participate or who were not able to understand the directions and content of the questionnaire were excluded. The medical personnel participated in this study were 56 residents or nurses who were working in either Neurology or Neuro surgery Units. The questionnaire consisted of 6 categories with a total of 79 questions. The responses were indicated on a 5point Likert scale with 5 indicating the highest need . The data were analyzed with descriptive statistics, students t-tests, and chi-square. RESULTS: Of the 90 patients and 56 medical personnel studied, the need for lifestyle information such as smoking, drinking, sleep, driving, employment, and marriage was significantly higher from medical personnel than that of the patients(p=0.00). Regarding medical knowledge about epilepsy, the patients group had higher scores in the need for information on the structure of the brain (p=0.00), whereas medical personnel had higher scores on the symptoms of epilepsy. There was no correlation between the length of epilepsy and the need for information on every item on the questionnaire. The patients had higher rank regarding diet, although it was not significantly different from the medical personnel. Regarding antiepileptic drugs and what to do when there is an attack, medical personnel scored higher. The items on which the patients group scored higher than 4.5 were the possibility of inheritance, the factors that might reduce the number of attacks, the period of usage of AED, and the food they have to avoid or the food they have to take to reduce seizure attacks. CONCLUSIONS: Our study indicates that the patients group requires higher educational need in the structure of the brain, diet, and surgical treatment, but less in lifestyles and what to do when there is an attack. The educational program for the patients with epilepsy should emphasize medical knowledge with regard to brain anatomy, what to eat and what to avoid, and details of surgical treatment.

N, N-dimethylformamide (DMF) is a solvent which is widely used in the industrial workplace. It causes the liver damages to the chronically exposed workers and is also well known as the harzadous material to generate occupational malignancies. DMF is mainly metabolized into N-hydroxymethyl-N-methylformamide (HMMF) by the microsomal cytochrome p-450. HMMF breaks down to NMF. However, the detailed mechanism of its toxicity are unknown. In this experiment, the metabolism and the toxicity of DMF was investigated using an isolated perfumed liver model. DMF (0, 10, 25mM) were added into recirculating perfusate of the isolated perfused rat liver. Samples were collected at 0, 30, 45, 60, 75, 90 minutes from inferior vena cava. The gas-chromatography was used to analyze the metabolite of DMF, The changes in the oxygen consumption rate by DMF were monitored during perfusion. The enzyme activity (AST, ALT, LDH) in the perfusate were treasured to find out whether DMF causers hepatotoxicity. As perfusion continued, DMF concentration in the perfusate decreased, and NMF 1.16mM was detected. The oxygen consumption rate increased both at 10mM and 25mM DMF concentration. However, when SKF 525A, a known inhibitor of cytochrome p-450, had been pretreated (300uM before DMF addition, the oxygen consumption rate was significantly inhibited, indicating that cytochrome p-450 system is responsible for the conversion to NMF. With DMF addition, the activity of AST, ALT, and LDH significantly increased time dependently and dose dependently. However, the pretreatment of perfused liver with SKF 525A shoved that the release of AST, ALT and LDH was inhibited. In summary, it is found that DMF is metabolized to NMF in liver, and that cytochrome p-450 mono-oxygenase is suggested to play a role in the biotransformation of NMF. The time course of BMF toxicity in relation to NMF formation is compatible with hypothesis that the hepatotoxicity of DMF is mediated via NMF. Further study combined with in vivo experiment through the toxicological approaches is expected.

Double-chamber right ventricle (DCRV) is a rare congenital heart disease consisting in right ventricular obstruction due to one or several anomalous muscle bundles that divide the right ventricle into two chambers. The right ventricular outflow tract obstruction is generally progressive in these patients. A ventricular septal defect is one of the commonly associated malformations. A 23-year-old woman with exertional dyspnea was admitted to our hospital and undertaken echocardiography, cardiac catheterization and both ventricular angiograms. The diagnosis was established and report with review of literatures.

BACKGROUND/AIMS: Endoscopic Mucosal Resection (EMR) and Endoscopic Submucosal Dissection (ESD) are novel techniques used for the treatment of early gastric cancer and precancerous lesions of the stomach. However, complications such as bleeding and perforation may occur during the procedure, and these complications may raise the morbidity and mortality rates. EMR/ESD-induced perforations can be treated with conservative medical or non-surgical methods. Furthermore, an increasing number of reports have addressed conservative management of EMR/ESD-induced perforations. We evaluated the effectiveness and safety of implementing conservative treatment for perforations associated with EMR and ESD. METHODS: We reviewed 482 patients with 507 lesions who underwent EMR or ESD due to early gastric cancers or gastric adenomas between February 2003 and December 2007. We identified 14 perforations occurring as complications of EMR/ESD and investigated their clinical outcomes. RESULTS: Fourteen perforations (14/507 [2.8%]) occurred, 11 of which were immediately clipped during the procedure, and 3 of which were diagnosed after the procedure when free air was visualized on the radiograph. All patients were managed conservatively with fluid resuscitation and antibiotics (mean, 5.8 days). They recovered without surgery and were discharged in stable condition at a mean of 7.2 days post-procedure. CONCLUSIONS: Endoscopic clip application might be an effective and safe option for conservative management of EMR/ESD-induced perforations.

BACKGROUND/AIMS: The diagnosis of clonorchiasis is based on demonstrating eggs in stool or bile. It is believed that bile examination is the most precise method for detecting eggs. We evaluated diagnostic usefulness of intradermal test (IDT) by comparing it with the result of bile examination. METHODS: For 88 patients with pancreatobiliary diseases, we examined Clonorchis sinensis eggs in bile and performed IDT for clonorchiasis. The bile was obtained from endoscopic nasobiliary or percutaneous transhepatic biliary drainage tubes. RESULTS: We calculated ROC curve to decide the cut-off value of IDT in determining diagnostic accuracy on the basis of bile examination. We chose a value of 40 mm2, which significantly improved the sensitivity, without reducing the specificity. With a cut-off value of 40 mm2, the sensitivity, specificity, positive and negative predictive values of IDT were 81.5%, 67.2%, 52.4%, and 89.1%, respectively. The value of IDT was not affected by age and showed no difference between benign and malignant diseases. However, in egg-positive patients, the mean value was lower in malignant diseases than in benign diseases. CONCLUSIONS: In patients with pancreatobiliary diseases, IDT with a cut-off value of 40 mm2 seems to be a valuable supplementary diagnostic test for clonorchiasis in view of its high sensitivity.

Nutcracker syndrome(renal vein entrapment syndrome) is probably more common than previously suspected. The nutcracker phenomenon refers to compression of left renal vein between aorta and superior mesenteric artery that results in elevation of pressure in left renal vein and develoment of collateral veins. This syndrome occurs in relatively young and previously healthy patients and is characterized by intermittent gross hematuria due to left renal vein hypertension, at times associated with flank pain, abdominal pain or varicocele. We report a 17 years-old male patient with this syndrome presented with flank pain, abdominal pain, and intermittent gross hematuria for 3 months. Urinalysis revealed protein(-), blood(+++), many RBC with only 1% of dysmorphic RBC. IVP and cystoscopy showed no remarkable finding but doppler ultrasonography and abdominal spiral CT revealed compression of left renal vein between aorta and superior mesenteric artery. Renal venography showed compression of left renal vein and collateral circulation to left gonadal vein and the pressure gradient between left renal vein and inferior vena cava was 11mmHg. The nutcracker syndrome should be considered as one of the causes of nonglomerular hematuria. All patients with unexplained severe left flank or abdominal pain, or unilateral hematuria from the left on cystoscopy, should be studied by selective renal venography and pressure measurement in inferior vena cava and renal veins. The patient with this typical syndrome could be treated surgically, by transposition of left renal vein and resection of collateral veins as the procedure of choice to correct the underlying pathologic process and eliminate these troublesome symptoms.
