PURPOSE: To report the initial clinical experience with single-incision laparoscopic gastric wedge resection for submucosal tumors. MATERIALS AND METHODS: The medical records of 10 patients who underwent single-incision laparoscopic gastric wedge resection between July 2009 and March 2011 were reviewed retrospectively. The demographic data, clinicopathologic and surgical outcomes were assessed. RESULTS: The mean tumor size was 2.5 cm (range, 1.2~5.0 cm), and the tumors were mostly located on the anterior wall (4/10) or along the greater curvature (4/10), of the stomach. Nine of ten procedures were performed successfully, without the use of additional trocars, or conversion to laparotomy. One patient underwent conversion to multiport laparoscopic surgery, to get simultaneous cholecystectomy safely. The mean operating time was 66.5 minutes (range, 24~132 minutes), and the mean postoperative hospital stay was 5 days (range, 4~7 days). No serious perioperative complications were observed. Of the 10 submucosal tumors, the final pathologic report revealed 5 gastrointestinal stromal tumors, 4 schwannomas, and 1 heterotopic pancreas. CONCLUSIONS: Single-incision laparoscopic gastric wedge resection for gastric submucosal tumors is feasible and safe, when performed by experienced laparoscopic surgeons. This technique provides favorable cosmetic results, and also short hospital stay and low morbidity, in carefully selected candidates.

BACKGROUND & METHODS: Approximately 10% of the essential hypertensive patient have overt proteinuria due to renal target organ damage, which indicates poor prognosis. Recently microalbuminuria has been prove to be a good early predictor for renal damage in patients with diabetes or hypertension. Some authors reported that near 40% of the essential hypertensives have microalbuminuria. To determinate prevalence of microalbuminuria in Korea essential hypertensives, 24-hr ambulatory blood pressure monitoring and radioimmunoassay to detect BP and UAER were performed after 4 weeks wash-out period in 137(78 hypertensive and 54 normotensive) consecutive cases. RESULTS: Among 78 hypertensives, overt proteinuria was seen in 8.97%(7/78). And prevalence of microalbuminuria were 29.4%(23/78) in hypertensives and 16.7%(9/54) in normotensives. Urine microalbumin excretion rate(UAER) was significantly correlated with mean arterial pressure(MAP) in total subjects(r=0.286, p=0.0012), but not in total hypertensives(r=0.135, p=NS) or in hypertensives with UAER(r=-0.098, p=NS).UAER of female hypertensives was increase than that of male hypertensives(13.17+/-16.28microg/min vs 22.87microg/min, p=0.027). CONCLUSION: Prevalence of microalbuminuria in Korean hypertensives was relatively lower then other reports. Overt proteinuria was noted in 8.97% of the hypertensives which is same prevalence as other countries. Moreover MAP was well correlated with UAER in total subjects. Further evaluation should be done to detect exact role of UAER in hypertensives as an early predictor for renal target organ damage.

BACKGROUND: Mesenteric infarction is a significant cause of death in elderly patients, and is being reported with increasing frequency. The diagnosis seldom is made prior to the onset of gangrene, despite an increased awareness of the lethality of mesenteric ischemia. The outcome for patients with mesenteric ischemia depends on the age of the patient, the extent and the severity of the ischemia and the effectiveness of the collateral blood supply. METHODS: We retrospectively reviewed the cases of 23 patient with mesenteric infarction who had been treated at the Department of Surgery, Hallym University, Chunchon Sacred Heart Hospital, between September 1988 and August 1977. RESULTS: The mean age was 52.3 years and the ratio of males to females was 1:1.6. The most frequent underlying diseases were hypertension, congestive heart failure, atrial fibrillation, and myocardial infarction. The radiologic study of a simple plain abdomen revealed a paralytic ileus in 87% of the cases; a partial vascular occlusion was shown under angiogram. The mean time lapse from onset of symptom to operation was 38.3 hours. Eight (34.8%) patients died when renal failure, ARDS or peritonitis developed. CONCLUSIONS: The cause of the persistently high mortality in patients with mesenteric in farction and to define a more effective form of management based on our results and recent clinical or laboratory findings. This study was concluded that early detection of the mesenteric infarction was reduced postoperative complications.

Laparoscopic gastrectomy was begun in 1995 in Korea. But, there was 4 years gap to reactivate in 1999. High incidence of gastric cancer and increasing proportion of early cancer through national screening program along with huge effort and enthusiasm of laparoscopic gastric surgeon, and active academic exchange with Japanese doctors contributed development of laparoscopic gastrectomy in Korea. Study group activity of Korean Laparoscopic Gastrointestinal Surgery Study (KLASS) group and Collaborative Action for Gastric Cancer (COACT) group were paramount to evoke large scale multicenter clinical study and various well performed clinical studies. This review encompasses mainly international publications about this area so far in Korea.

Pulmonary arteriovenous fistula (PAVF) is a complication of the Glenn shunt. A 57-year-old tetralogy of Fallot (TOF) patient, who had undergone a Glenn shunt and TOF total correction, complained of dyspnea and cyanosis. PAVFs were present in the right lung, and right lung perfusion was nearly absent. After coil embolization, takedown of the Glenn shunt, and reconstruction of the right pulmonary artery, the patient's symptoms were relieved. Extrapulmonary radioisotope uptake caused by the PAVFs shown in lung perfusion scans decreased, and right lung perfusion increased gradually. Although the development and resolution of PAVFs after a Glenn shunt have been reported in the pediatric population, this may be the first report on this change in old age.

Kounis syndrome is an acute coronary syndrome concurrently occurs with allergic or hypersensitivity reactions. In patient with this syndrome, inflammatory mediators released due to an allergic reaction implicate to induce coronary artery spasm and atheromatous plaque rupture. We describe a patient with coronary artery disease who developed acute perioperative myocardial infarction leading to cardiac arrest after the anaphylactic reaction to cisatracurium, which led to a suspicion of Kounis syndrome. Anesthesiologists should be aware that anaphylaxis or allergic reactions can progress to acute coronary syndrome, thereby significantly change the course of the disease.

Background: F-18-fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT) can be used to measure bone mineral density (BMD), cross-sectional muscle area (CSMA), Hounsfield units (HU) of liver and muscle, subcutaneous adipose tissue (SAT), abdominal visceral adipose tissue (VAT), and glucose metabolism. The present study aimed to identify age-related changes in body composition and glucose metabolism in Korean using opportunistic FDG-PET/CT imaging. Methods: We analyzed FDG-PET/CT, clinical history, and laboratory data abstracted from the medical records of patients who underwent health screening at a single institute between 2017 and 2022. Results: In total, 278 patients were included in the analysis (male:female=140:138). Age and body mass index were positively correlated in female, but negatively correlated in male. BMD decreased with age more in female, and CSMA decreased with age more in male. Muscle HU decreased with age for both sexes. In female, SAT and VAT increased with age; and in male, SAT decreased slightly while VAT remained stable. Muscle glucose metabolism showed no association with age in male but increased with age in female. CSMA correlated positively with BMD overall; and positively correlated with VAT and SAT in male only. In female only, both SAT and VAT showed negative correlations with glucose metabolism and correlated positively with muscle glucose metabolism. Liver HU values were inversely correlated with VAT, especially in female; and positively correlated with muscle glucose metabolism in female only. Conclusion FDG-PET/CT demonstrated distinct patterns of age-related changes in body composition and glucose metabolism, with significant differences between sexes.
