Purpose: Over the past few decades, the treatment of traumatic splenic injuries has shifted to nonoperative management from surgical intervention. Although some nonoperative management failure have been reported, in most trauma centers, nonoperative management is now believed to be the treatment of choice in hemodynamically stable patients. Then, in this study, we have retrospectively evaluated our experience with traumatic splenic injury. Methods: From January 2005 to July 2009, 150 patients with blunt splenic injuries were managed in our hospital. Patients``charts were retrospectively reviewed to analyze their treatment, the patients were grouped according to those who had been admitted before October 2006, defined as the early group, and those who had been admitted after October 2006, defined as the late group. After the patients had been divided into two group, physiologic parameters and differences between the treatments were compared. Results: 150 patients were admitted to our hospital with blunt splenic trauma. In late group, both the surgical management rate and the nonoperative management failure rate were lower than they were in the early group. Conclusion: We expect angioembolization to effectively replace surgery for the treatment of selected patients with blunt splenic injury and to result in fewer complications.

Purpose: Combined organ resection is a common operation in gastric cancer surgery. The aim of this study is to investigate the risk of combined minor organ resection (GB, gynecologic organ, appendix etc) in gastric cancer surgery. Methods: The clinical data from 673 consecutive patients who underwent gastrectomy for gastric cancer at a single center were retrospectively analyzed. We investigated clinical data between open groups (OG) and laparoscopy groups (LAG), and we divided the patients into 3 groups: no resection group, minor organ resection group and major organ (spleen, pancreas, and colon) resection group. Results: There were higher complication rates in major organ resection group (59.3%, 53.8%) than no resection (32.3%, 19.1%) or minor organ resection groups (38.7%, 20%) both in OG and LAG (P<0.05). However, there were longer hospital stays in minor (22.2 days) and major resection groups (24.1) than no resection group (16.2) in OG, but stays were longer in major resection group (30.9) than minor (14.5) and no resection group (16.2) in LAG (P<0.01). Operative times were longer in minor (287 min) and major organ resection group (310) than no resection group (243) in OG (P<0.00). However, operation time was longer in major resection group (505) than minor (415) and no resection group (370) in LAG (P=0.00). Conclusion: Combined minor organ resection with gastrectomy does not increase morbidity, and there is no statistical difference in hospital stay and op time than no resection group in LAG.

Purpose: Recently, there have been several studies on the early results of hepatectomy for various intrahepatic lesions. We report the early experience of our hospital after total laparoscopic left hepatectomy in patients with intrahepatic stones in the left hemi-liver. Methods: We retrospectively analyzed the medical records of patients who were diagnosed with left intrahepatic stones and underwent hepatectomy between January 2007 and June 2009. The patients were grouped according to operative procedure into open hepatectomy, laparoscopy-assisted hepatectomy, and total laparoscopic hepatectomy. Results: There were 31 patients who underwent Lt hemihepatectomy and Lt lateral sectionectomy during this period. Hepatectomy with open method, laparoscopy-assisted method, and total laparoscopy method were performed in 10, 14, and 7 cases. There were no significant differences between the three methods for operating time and postoperative complications. But the number of fasting times and hospital days was shorter with total laparoscopic hepatectomy than with others. Conclusion: Total laparoscopic liver resection is a safe and useful method for treating patients with intrahepatic stones and offers the advantage of quick patient recovery. Careful selection of appropriate patients and further development in the laparoscopic surgical technique resulting from accumulated experiences will help enable the laparoscopic hepatectomy to be performed more easily and safely in patients with intrahepatic stones.

We experienced a rare case of colonic cryptococcosis in an apparently immunocompetent individual. A 27-year-old woman admitted our hospital for intermittent melena. Initial abdominal CT scan revealed a mass lesion obstructing most of the lumen in ascending colon. Colonoscopy showed huge ulcerofungating mass in proximal ascending colon. Colonoscopic biopsy was performed and pathologic diagnosis was made as colonic cryptococcosis with positive PAS stain. Laboratory test evaluating immune status and bone marrow examination was normal. The patient was treated with intravenous amphotericin B for four weeks and six months of oral fluconazole afterwards. Follow-up abdominal CT scan and colonoscopy were taken at four weeks and seven months after the beginning of treatment. On completion of intravenous amphotericin B treatment, the mass lesion was decreased in abdominal CT and colonoscopy. After seven months, abdominal CT and colonoscopy showed near-complete resolution of the colonic lesion so the treatment ended. Cryptococcosis in a healthy individual is a rare disease and there have been only several sporadic case reports on pulmonary or central nervous system involvement. Hence, we report a case of colonic cryptococcosis in an apparently immunocompetent individual. (Korean J Gastroenterol 2008;52:255-260)

This study was performed to figure out the effects of I-razin in overweight children without any exercise or specific diet. Methods Twenty-eight children those who were diagnosed overweight have been recruited. They were randomly assigned treatment or control group under block randomization. Treatment group were treated with I-razin for 8 weeks, and control group were treated with placebo medication under same conditions. Anthropometry, fat computed tomography and blood test have been done before and after the treatment. Results Eleven subjects in treatment group and seventeen in control group were evaluated. BMI, waist circumference, glucose, total cholesterol, and triglyceride were decreased in the treatment group. And reduction of BMI, glucose, and triglyceride in the treatment group were greater than control group. But there was no statistically significance. No side effects have been notice during the study period and no adverse effect on liver has been observed. Conclusion This study could not demonstrate effect of I-razin compared with control group. However, treatment group has a tendency of weight loss without side effect. Additional studies with large population are thought to be necessary to clarify the effect of I-razin.

본 연구의 목적은 현장타설말뚝에 발생한 네킹 결함을 평가하기 위해 전자기파의 적용성을 검증하는데 있다. 본 연구에서는 네킹 결함이 있는 직경 150mm, 길이 270mm의 소형 모형 말뚝에 대해 실험을 수행하였다. 말뚝에 모사된 결함은 총 4개이며, 이 중 두 개의 결함은 모형 말뚝의 서로 다른 면의 상부와 하부에 각각 모사되었으며, 나머지 두 개의 결함은 같은 면의 상부와 하부에 모사되었다. 전선을 철망을 이루고 있는 스테인리스 재질의 철사를 따라 설치하여 두개의 도체로 구성된 전송선로를 구성하였으며, time-domain reflectometer를 이용하여 전자기파를 송 수신하였다. 실험 결과, 모형 말뚝의 결함부와 선단부에서 전자기파의 반사 신호가 나타났다. 측정된 반사 신호로부터 결함의 위치를 산정한 결과, 실제의 결함 위치와 거의 같게 산정되었다. 본 연구의 결과는 전자기파가 현장타설말뚝의 네킹 결함을 평가하는데 있어 유용한 기법이 될 수 있음을 보여준다. The objective of this study is to demonstrate the suitability of electromagnetic waves for evaluating necking defects in bored piles using electromagnetic waves. Experiments are conducted with small-scaled defective model pile with diameter of 150 mm and length of 270 mm. Two necking defects are generated at the upper and lower positions on two different sides of the model pile, respectively. The other two necking defects are generated at the upper and lower positions on the same side of the model pile. Electrical wires are installed alongside the stainless steel wire of a steel cage to configure a two-conductor transmission line. A time-domain reflectometer is used to generate and defect electromagnetic waves. The experimental results show that electromagnetic waves are reflected at the necking defects and the end of the model pile. In addition, calculated defect locations are almost the same as actual defect locations. This study demonstrates that electromagnetic waves can be effective tool for evaluating necking defects in bored piles.

Adrenal cysts are a relatively uncommon disorder and most such cases are discovered at autopsy. According to the overseas cases, the reported incidence is 0.06∼0.18% and the incidence is increasing due to the widespread use of ultrasonography and computed tomography scanning. Adrenal cysts are usually asymptomatic and they need to be differentiated from other cystic lesions including liver, pancreas and kidney cystic lesions. We report here on a case of a 39-year-old female with an adrenal pseudocyst that was misdiagnosed preoperatively as a pancreas mucinous cystic neoplasm. (Korean J Endocrine Surg 2009;9: 30-32)

Objectives: This study was performed to figure out the effects of herbal mesotherapy on abdominal fat in obese women. Methods: Forty obese women those who were diagnosed abdominal obesity had been recruited during February, 2008. They were randomly assigned experimental or control group under block-randomization. Experimental group were treated with Sobi-eum(Xiaofei-yin) injection during 6 weeks (2 times a week) and placebo group were treated with normal saline injection under same procedures. Anthropometry, body impedance analysis, fat computed tomography, blood test, and questionnaires had been administered before and after the treatment. Results: Four subjects were dropped out (voluntary give up), so 18 in experimental group and 18 in placebo group were evaluated. There were significant changes after treatments in both groups. Although no significant differences have been found in the result of anthropometry, body impedance analysis and fat computed tomography between two groups, in the experimental group, the changes of total fat area had a highly significant relationship with all part of abdominal fat. While the placebo group had highly significant relationships with subcutaneous fat area, superficial and deep subcutaneous fat area but not with visceral fat area. Conclusions: Compaired with saline group, herbal mesotheraphy Sobi-eum(Xiaofei-yin) is effective in reduction of visceral fat after adjusting TFA.
