Primary iliopsoas abscess, without a causative infection focus, is a very rare kind of retroperitoneal abscess. Immunocompromised patient, such as elderly patients, diabetics and patients with chronic disease, are susceptible to this kind of infection. Because early diagnosis of priiliopsoas abscess is usually delayed due to nonspecific clinical presentation, proper treatment is also delayed which causes high mortality and morbidity. Recently we experienced three cases of primary iliopsoas abscess due to Staphylococcus aureus. Diagnosis of these cases was belatedly confirmed by using a abdominal-pelvic computerized tomography (CT) scan. Open surgical drainage via an extraperitoneal approach and administration of appropriate systemic antibiotics were required to save these patients. Based on a review of the literature, we evaluated the diagnosis and treatment of primary iliopsoas abscess.

Adrenocortical oncocytoma is a rare adrenal neoplasm with only 25 cases having been reported in the English medical literature, of which only seven were functional tumors. Since these adrenal tumors are usually nonfunctional, they are mostly incidentally detected, and most of them are benign. Herein, we report on a rare case of a functional adrenocortical oncocytoma of an uncertain malignant potential and this tumor was located in the left adrenal gland in a 59-year-old woman who presented with hypertension. The tumor size was large with foci of necrosis in the cut surface and it exclusively had oncocytic histologic features.

PURPOSE: The main issue with the current ultrasonography (US) guidelines is the overestimation of malignant and indeterminate nodules as they do not aid in making decisions to treat patients. To overcome this, new US guidelines for thyroid nodules that have been shown to be better correlated with cytologic results have been proposed. We also suggested specific indications for US-guided fine needle aspiration (FNA) using the new US guidelines. METHODS: Clinical and pathologic data from 925 patients and 1,419 thyroid nodules were retrospectively collected. All subjects underwent US- and US-guided FNA at Department of Surgery, Wonju Christian Hospital, between March 2010 and July 2011. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) were calculated for both the current guidelines and the new guidelines. RESULTS: The accuracy, sensitivity, specificity, PPV, and NPV for the current guidelines in predicting malignancy were 24.1%, 99.3%, 62.2%, 25.0%, and 99.8%, respectively. The accuracy, sensitivity, specificity, PPV, and NPV for the new guidelines in predicting malignancy were 66.0%, 96.0%, 86.7%, 47.7%, and 99.4%, respectively. CONCLUSION: The use of the new US guidelines allow for a more accurate and specific diagnosis and a better treatment plan than the current guidelines. Additionally, the use of the new FNA guidelines may help prevent unnecessary FNAs and promote cost-effective follow-up for patients.

Abdominal tuberculosis is a rare disease, about 5% of extra-pulmonary tuberculosis. However, the diagnosis of abdominal tuberculosis is difficult, because of its atypical symptoms and signs, and ambiguous results upon physical examination. When abdominal tuberculosis is combined with abdominal injury, the diagnosis will be especially complex. We present our experience of abdominal tuberculosis associated with abdominal trauma.

Osteogenesis imperfecta is a relatively rare genetic condition of breakable bones with an incidence of 1 per 20,000~60,000. The clinical, genetic, and biochemical heterogeneity in osteogenesis imperfecta allows to least four subtypes to be distinguished. Prenatal diagnosis of osteogenesis imperfecta type II have been reported several times with ultrasonography. We recently experienced a case of osteogenesis imperfecta diagnosed in uterus by ultrasonogram and confirmed after termination and autopsy. We report here with a brief review of the literature.

PURPOSE: Trauma is the 5th most common leading cause of death in Korea, but there has been no appropriate management system for patients until now. We analyzed the main causes of death in trauma patients by comparing the characteristics of those patients with the characteristics of patients who survived. We feel this analysis should have a positive effect on the development of an appropriate trauma management system in Korea. METHODS: We retrospectively reviewed trauma patients who had been admitted to the Department of General Surgery from February 2002 to February 2007. We compared several expected risk factors between the mortality and the survival group. Data on the transportation, arrival time at the emergency center, amount of transfusion, initial shock index, cause of death, and initial physical condition according to RTS (Revised trauma score), ISS (Injury severity score) and TRISS (Trauma and Injury Severity Score) were collected. Patients with ISS lower than 12 were excluded. RESULTS: Three hundred sixty-six(366) patients with multiple injuries were included. There were 40 patients in the mortality group and 326 patients in the survival group. The mean arrival time (minutes) to emergency center was longer in the mortality group (137.6 vs 93.6 p 0.04). The total amount of transfusion (ml) was larger in the mortality group (7139 vs 2470 p 0.01). The initial shock index was higher in the mortality group (1.45 vs 1.17 p<0.01). The RTS, ISS, and TRISS were not statistically different between the groups. In the multivariate analysis, mean arrival time and initial shock index were important factors for survival. CONCLUSION: If the mortality rate of trauma patients is to be reduced , the arrival time at the emergency center should be minimized. Improvement of the emergency medical transfer service system is very important for achieving that.

PURPOSE: An Incidence of primary iliopsoas abscess is extremely rare. So it's clinical features are unclear. We reported the clinical features and treatment of primary iliopsoas abscess with reference review. METHODS: The ten cases of primary iliopsoas abscess from January 1999 to August 2003 were included in this study. We analyzed clinical manifestation, diagnostic modality, treatment and prognosis retrospectively. Microbiologic study and imaging study were performed in all patients. The treatments included surgical drainage, percutaneous drainage, and systemic antibiotics only were performed. RESULTS: In demographics of patient, the sex ratio was equal and mean age was 51.8 years old with predominant elderly (more than 60 years old). The abscess was confirmed by computed tomography in 8 patients, magnetic resonance imaging in 1. One abscess was found after laparotomy. The one side iliopsoas abscess was found in eight cases (right 4 cases and left 4) and bilateral abscess was in two cases. All cases were multilobulated abscess. After failure of percutaneous drainage, surgical drainage with retroperitoneal approach was performed in 8 patients. Transperitoneal drainage and systemic antibiotics therapy without drainage was respectively performed in one case. One case of abscess was recurred due to early removal of drain and insufficient antibiotics therapy. Other nine patients were completely resolved without complication or mortality. CONCLUSION: The diagnosis of primary iliopsoas abscess requires a high index of suspicion due to its rarity. If we consider that most iliopsoas abscess was multi-lobulated, early surgical drainage with sufficient administration of systemic antibiotics is an effective treatment modality.

PURPOSE: This study evaluated the association of the BRAF(V600E) mutation with known prognostic factors and ultrasonographic characteristics in cases of papillary thyroid carcinoma. METHODS: Subjects included 169 patients who received thyroidectomy at Wonju Christian Hospital under the diagnosis of papillary thyroid cancer from February 2010 to October 2011. RESULTS: Of the total patients who received thyroidectomy, there were 128 cases (75,7%) of BRAF(V600E) mutation. Neither age nor sex were associated with the BRAF(V600E) mutation. Tumor size, shape, margin, extrathyroidal extension, central node metastasis and lateral node metastasis were found not to be associated with the BRAF(V600E) mutation. Tumor calcification, echogenicity and vascularity were also not associated with the mutation. CONCLUSION: As debate remains about the association between the BRAF(V600E) mutation and clincopathologic factors and ultrasonographic characteristics in cases of papillary thyroid carcinoma, further study is needed.

PURPOSE: Recently, the change to a more complex social structure has led to an increased frequency of traumas due to violence, accident and so on. In addition, the severity of the traumas and the frequency of penetrating injuries have also increased. Traumas to cervical and abdominal areas, what are commonly seen by general surgeons, can have mild to fatal consequences because in these areas, various organs that are vital to sustaining life are located. The exact location and characteristics of the injury are vital to treating patients with the trauma to these areas. Thus, with this background in mind, we studied, compared, and analyzed clinical manifestations of patients who were admitted to Wonju Christian hospital for penetrating injuries inflicted by themselves or others. METHODS: We selected and performed a retrospective study of 64 patients who had been admitted to Wonju Christian Hospital from January 2005 to December 2009 and who had cervical or abdominal penetrating injuries clearly inflicted by themselves or others. RESULTS: There were 51 male (79.7%) and 13 female (20.3%) patients, and the number of male patients was more dominant in this study, having a sex ratio of 3.9 to 1. The range of ages was between 20 and 86 years, and mean age was 43.2 years. There were 5 self-inflicted cervical injuries, and 19 self-inflicted abdominal injuries, making the total number of self-inflicted injury 24. Cervical and abdominal injuries caused by others were found in 11 and 29 patients, respectively. The most common area involved in self-inflicted injuries to the abdomen was the epigastric area, nine cases, and the right-side zone II was the most commonly involved area. On the other hand, in injuries inflicted by others, the left upper quadrant of the abdomen was the most common site of the injury, 14 cases. In the neck, the left-side zone II was the most injured site. In cases of self-inflicted neck injury, jugular vein damage and cervical muscle damage without deep organ injury were observed in two cases each, making them the most common. In cases with abdominal injuries, seven cases had limited abdominal wall injury, making it the most common injury. The most common deep organ injury was small bowel wounds, five cases. In patients with injuries caused by others, six had cervical muscle damage, making it the most common injury found in that area. In the abdomen, small bowel injury was found to be the most common injury, being evidenced in 13 cases. In self-inflicted injuries, a statistical analysis discovered that the total duration of admission and the number of patients admitted to the intensive care unit were significantly shorter and smaller, retrospectively, than in the patient group that had injuries caused by others. No statistically significant difference was found when the injury sequels were compared between the self-inflicted-injury and the injury-inflicted-by-others groups. CONCLUSION: This study revealed that, in self-inflicted abdominal injuries, injuries limited to the abdominal wall were found to be the most common, and in injuries to the cervical area inflicted by others, injuries restricted to the cervical muscle were found to be the most common. As a whole, the total duration of admission and the ICU admission time were significantly shorter in cases of self-inflicted injury. Especially, in cases of self inflicted injuries, abdominal injuries generally had a limited degree of injury. Thus, in our consideration, accurate injury assessment and an ideal treatment plan are necessary to treat these patients, and minimally invasive equipment, such as laparoscope, should be used. Also, further studies that persistently utilize aggressive surgical observations, such as abdominal ultrasound and computed tomography, for patients with penetrating injuries are needed.

PURPOSE: Trauma is an important cause of death in children. In particular, the liver is the second most commonly organ injured by blunt abdominal trauma. Treatment of patients with liver injury is has changed, and non-operative treatment is the major treatment method at present. In this study, we reviewed traumatic liver injury in pediatric patients. METHODS: Seventy-seven patients younger than 16 years of age with traumatic liver injury were assessed for 10 years from July 1999 to June 2009 at Wonju Christian hospital. Records of the patients were reviewed retrospectively. Demographic and clinical data were analyzed. RESULTS: The median age was 6 years, and the male-to-female ratio was 1.2 : 1. The most common injury grade was grade I. The majority of injuries were caused by was traffic accidents, and the second most common cause of injuries was falls. Twenty-four patients had liver injuries alone, and the most common accopaning injury was a lung injury. The average hospital stay was 20.7 days, and the average ICU stay was 4.8 days. Four patients died (5.2%). There were 6 patients with under 10 points on the Glasgow coma scale (GCS). Among these patients, three died. All mortality cases had over 16 points on the Injury Severity Score (ISS). Two patients were treated surgically, one of whom died. Of the 75 patients with non-operative management, three died due to associated injuries. CONCLUSION: Most pediatric patients with liver injury have good results with non-operative management. Associated injuries and hemodynamic instability are predictive of patient outcome, and those with isolated liver injuries can be successfully managed non-operatively.
