PURPOSE: With the technical advancement in arterial embolization and subsegmental resection of liver neoplasm, emphasis has been on more detailed knowledge of normal arterial anatomy and its variation. We analysed the patterns of intrahepatic branches of right hepatic artery. MATERIALS AND METHODS: We retrospectively analyzed intrahepatic branching patterns of right hepatic artery in 165 cases. All cases had a single right hepatic artery which could be traced up to tertiary branches, and also performed rapid drip infusion CT scan, hepatic arteriography with antero-posterior and oblique views, superior mesenteric arteriorgraphy and indirect portography. RESULTS: lntrahepatic branching patterns of the right hepatic artery had eight types of variation. The most common intrahepatic branching pattern was type I: 107(64.5%) which represented 5, 8th branch emerging from the anterior segmental artery and 6, 7th branch from the posterior segmental artery. Type VII :26(15.8%) was the next common type which represented 6th branch emerging first from the posterior segmental artery and 7th branch emerging secondly from the posterior segmental artery. Type VII, VI, III were branched from the posterior segmental artery. Type IV, II, V were branched from the anterior segmental artery. CONCLUSION: These result could be helpful to the planning of treatment, such as hepatic subsegmentectomy or transarterial embolization of the hepatic neoplasm.

PURPOSE: Recently, early gastric cancer has increased in Korea. Thus, endoscopic resection and laparoscopic gastrectomy has increased in early gastric cancer patients. But, endoscopic resection of early gastric cancer has many problems such as poor long-term survival data, diverse endoscopic techniques, ambiguous follow-up strategy, nonuniform pathologic interpretation and so on. We studied patients that received additional gastrectomy after EMR/ESD. We analyzed clinicopathological characteristics states before and after EMR/ESD. METHODS: From 1998 to 2008, 56 patients received additional gastrectomy after EMR/ESD due to gastric cancer. We analyzed tumor characteristics, endoscopic resection type, reasons for gastrectomy, post-operative characteristics, etc., retrospectively from medical records. RESULTS: The ratio of male to female was 2:1. Six patient tumors were larger than 2 cm in size. Forty-five patients received EMR and 12 patients received ESD. Common macroscopic feature of endoscopic findings were superficial elevated and superficial depressed between 10 mm and 20 mm. Forty patients received immediate gastrectomy due to incomplete endoscopic resection. Sixteen patients received additional gastrectomy during follow-up period after EMR/ESD. The most common reason of immediate gastrectomy was positive resection margin. The most common reason of follow-up gastrectomy was cancer recurrence. Three patients had advanced gastric cancer in follow up gastrectomy group. Two patients died due to gastric cancer in immediate gastrectomy group and follow-up gastrectomy group. CONCLUSION: Active effort for surgical treatment is needed when the gastric cancer characteristics of patients is inadequate for endoscopic resection. Uniform pathologic interpretation is essential for confirming completeness of endoscopic resection. Treatment and follow-up strategy after endoscopic resection is important due to recurrence and new cancer occurrence. Long-term and prospective randomized study should be performed to confirm safety and difficulty of endoscopic resection.

The incidence of W-P-W syndrome is often noted in patients without other evidence of heart diseases. However, most of them wlll have supraventricular arrhythmias, characterized by paroxismal tachyarrhythmias. W-P-W- syndrome may be complicated by severe hypotension, syncope, congestive heart failure, atrial and/or ventrioular fibrillation and even sudden death, We experienced a case of W-P-W syndrome Immediately after induction of general anes-thesia on a patient with preoperatively normal ECG patterne and no evidence of otder heart disease.

BACKGROUND AND PURPOSE: The pathogenesis of mitochondrial disease (MD) involves the disruption of cellular energy metabolism, which results from defects in the mitochondrial respiratory chain complex (MRC). We investigated whether infants with MRC I defects showed ultrastructural changes in skeletal muscle. METHODS: Twelve infants were enrolled in this study. They were initially evaluated for unexplained neurodegenerative symptoms, myopathies, or other progressive multiorgan involvement, and underwent muscle biopsies when MD was suspected. Muscle tissue samples were subjected to biochemical enzyme assays and observation by transmission electron microscopy. We compared and analyzed the ultrastructure of skeletal muscle tissues obtained from patients with and without MRC I defects. RESULTS: Biochemical enzyme assays confirmed the presence of MRC I defects in 7 of the 12 patients. Larger mitochondria, lipid droplets, and fused structures between the outer mitochondrial membrane and lipid droplets were observed in the skeletal muscles of patients with MRC I defects. CONCLUSIONS: Mitochondrial functional defects in MRC I disrupt certain activities related to adenosine triphosphate synthesis that produce changes in the skeletal muscle. The ultrastructural changes observed in the infants in this study might serve as unique markers for the detection of MD.

PURPOSE: Peritoneal seeding of gastric cancer is known to have a poor prognosis. With the diagnosis of peritoneal seeding, there is no effective treatment modality. Gastrectomy with chemotherapy or primary chemotherapy is basically one of major options for this condition. This study was conducted to compare the clinical outcomes of these treatments and to identify the better way to improve the prognosis of patients with peritoneal seeding. MATERIALS AND METHODS: Between 2001 and 2007, gastric cancer patients with peritoneal seeding by preoperative or intraoperative diagnosis were reviewed retrospectively. The enrolled patients were divided as primary gastrectomy and primary chemotherapy group. Clinicopathologic characteristics and clinical outcomes of groups were analyzed and compared. RESULTS: Fifty-four patients were enrolled. 21 patients belonged to the group of primary gastrectomy and 33 patients were to the primary chemotherapy group. Among 33 patients of the primary chemotherapy group, 17 patients were received only chemotherapy and 16 patients were received gastrectomy due to the good responses of primary chemotherapy. The 3 years survival rates were 14% in primary gastrectomy group, 55% in patients who received gastrectomy after primary chemotherapy, and 0% in patients with primary chemotherapy only. CONCLUSIONS: Although this study had many limitations, some valuable information was produced. In terms of survival benefits for the gastric cancer patients with peritoneal seeding, primary gastrectomy and additional gastrectomy after primary chemotherapy revealed the better clinical outcomes. But, prospective randomized clinical study and multi-center study are should be performed to decide proper treatment for gastric cancer patients with peritoneal seeding.

Solitary fibrous tumors (SFTs) are an uncommon neoplasm characterized by the proliferation of spindle cells. The diagnostic criteria of malignant solitary fibrous tumors (MSFTs) include high cellularity, high mitotic activity (4>10 HPF), pleomorphism, hemorrhage and necrosis. This tumor frequently involves the pleura and MSFTs of retroperitoneum mimicking gastric submucosal tumor are very rare. We report a rare case of MSFT that presented as a gastric submucosal tumor. A gastroscopic examination showed a large bulging mucosa in the gastric body. Abdominal computed tomography revealed a well-defined heterogeneous enhancing mass between the left hepatic lobe and gastric body. Surgical resection was performed and histologic features were consistent with a MSFT.

Asthma is a common medical syndrome which significantly increases the morbidity and mortality of surgical and anesthetic procedures. The anesthesiologist should be closely involved in the preoperative assessment and Prep-aration of these patients for, surgery and anesthesia and should be continually aware of the possibility of bronchospasm. The safe clinical management of this challenging population group demands not only expertise in carefully planning an anesthetic technique best suited to an individual patient and his specific disease process. We reported a case of bronchospasm after injection of neostigmine intravenously in 34-rear old female patient during endotracheal general inhalation anesthesia, together with brief of review of literature.
