Being described first 1912 by Hashimoto, Chronic lymphocytic thyroiditis has been most commonly diagnosed as inflammatory thyroid disease. Despite of worldwide reports about the concomitant malignancy with Hashimoto's thyroiditis, the definite incidence of coexsiting malignancy and the etiologic relationship between these different pathologic conditions remains to be brought out. Analyzing 18 cases of coexisting thyroid carcinoma among 80 cases of Hashimoto's thyroiditis, confirmed by pathologic study at Presbyterian medical center in Chonju between 1991 and 1995, the authors intended to make guideline of management for them. The results are as follows: 1. The incidence of coexisting carcinoma with HT was 18/80(22.5%). 2. The average age of patients with coexisting carcinoma was 44.1 years and all of them were female.3. Cold nodules on thyroid scan were noticed in 23 cases(22.7%) of HT and 7 cases(33.8%) of coexisting carcinoma with HT. 4. Calcified lesions on thyroid sonography were detected in 0 cases of HT and 4 cases(50%) of coexisting carcinoma. 5. The pathologic types of carcinoma were papillary(17/18, 94.4%) and follicular(1/18, 5.6%). 6. 3 cases of coexisting carcinoma had metastatic lesions on peritracheal lymph nodes and another 3 cases had on ipsilateral jugular nodes. 7. The carcinoma of smaller than 0.5cm were 7 cases, of 0.6-1.0cm were 3 cases, of 1.1-1.5cm were 5 cases, and so 15 cases(83.3%) were occult carcinoma. Only 3 cases were larger than 1.6cm. 8. Coexisting carcinoma patients with HT underwent subtotal thyroidectomy (4 cases), subtotal thyroidectomy & anterior compartment dissection (ACD, 6 cases), subtotal thyroidectomy & modified RND (2 cases), thyroid lobectomy & ACD (4 cases), thyroid lobectomy & modified RND (1 cases), or near total thyroidectomy & ACD (1 case).

Internal abdominal hernias are an unusual cause of intestinal occlusion. They are responsible for 2% of all the intestinal obstructions. Various types of hernia have been described. Paraduodenal hernias are relatively rare congenital malformations and result from incomplete rotation of the midgut with entrapment of the small intestine beneath the developing colon. We report a case of paraduodenal hernia of the small intestine in a 32-year-old man with presentation of intestinal obstruction. The patient suffered from nausea, vomiting and acute abdominal pain for 9 hours. Abdominal CT showed sac-like mass of clustered, dilatated small bowel in the right upper quadrant. At operation, herniation of small intestine into a retroperitoneal space through a defect on right mesocolon was noted. A right paraduodenal (mesocolic) hernia was diagnosed. The patient made an uneventful recovery except some diarrhea after extensive segmental resectio of strangulated small bowel. Paraduodenal hernia is important as it usually presents as intestinal obstruction, and is often misdiagnosed before laparotomy. Mortality is increased significantly with delays in surgical treatment. Though rare, paraduodenal hernia should be taken into account in a differential diagnosis of intestinal obstruction. Early surgical intervention allows uneventful recovery and also prevents the possible complication of gangrenous bowels.

OBJECTIVE: The study was undertaken to evaluate clinical safety and usefulness of laparoscopic myomectomy with analyzing clinical course and postoperative complications of 93 patients underwent laparoscopic myomectomy at Yosu Chon-nam Hospital and to introduce operative methods executed in this hospital. METHODS: Total number of patients underwent laparoscopic myomectomy at Yosu Chon-nam Hospital from May 2001 to December 2002 was 93. With ward chart and admission recordings, Age, parity, symtom, size of myoma, number of myoma, location operation time and hemoglobin change were recorded. Data were analyzed with Microsoft Excel. RESULTS: The mean age of patients was 42.68 ( +/- 6.05) years. The mean parity was 2.02 ( +/- 0.96). The mean number of myoma was 1.70 ( +/- 1.27). The mean weight of myoma was 71.7 ( +/- 56.4) gm. The most common symtom was hypermenorrhea. The location of myoma was submucosal, intramural, subserosal in large order. The mean operation time was 101.1 ( +/- 30.2) minutes. The mean hemoglobin change after operation was 1.40 ( +/- 0.81) g/dL. Mean hospital stay was 3.90 ( +/- 1.20) days. The operative complication was trocar site bleeding (2 cases), surgical emphysema (2 cases). In 2 cases, Laparoscopic procedure was converted to laparotomic method. CONCLUSION: Indication of operation was extended in almost all age (including reproductive age) and 93 Laparoscopic myomectomy was done safely and effectively without severe complications. However, to obtain more safety and usefulness of laparoscopic myomectomy, adequate laparoscopic instrument and expertized operative technic should be demanded. In near future, laparoscopic myomectomy will be more popular and effective by variable technical development and ordered discipline.

Reports of metastatic hepatocellular carcinoma (HCC) without a primary liver tumor are rare. Here we present a case of isolated HCC that had metastasized to the pelvic bone without a primary focus. A 73-year-old man presented with severe back and right-leg pain. Radiological examinations, including computed tomography (CT) and magnetic resonance imaging (MRI), revealed a huge mass on the pelvic bone (13x10 cm). He underwent an incisional biopsy, and the results of the subsequent histological examination were consistent with metastatic hepatocellular carcinoma. The tumor cells were positive for cytokeratin (AE1/AE3), hepatocyte paraffin 1, and glypican-3, and negative for CD56, chromogranin A, and synaptophysin on immunohistochemical staining. Examination of the liver by CT, MRI, positron-emission tomography scan, and angiography produced no evidence of a primary tumor. Radiotherapy and transarterial chemoembolization were performed on the pelvic bone, followed by systemic chemotherapy. These combination treatments resulted in tumor regression with necrotic changes. However, multiple lung metastases developed 1 year after the treatment, and the patient was treated with additional systemic chemotherapy.

BACKGROUND AND OBJECTIVES: As a society develops, olfactory disturbance increases with the increased industrial disaster, traffic accidents, upper respiratory tract infection, chronic sinusitis and allergic rhinitis from air pollution, Parkinson's disease and Alzheimer's disease from aging process. Nevertheless, there is no practical clinical test of olfactory function in Korea. Authors decided to develop the "Korean olfactory test" using the odorants which are familiar to Koreans. MATERIALS AND METHODS: KVSS Test (Korean Version of Sniffin' Sticks Test) is composed of KVSS Test I (screening test) and KVSS Test II (comprehensive test). KVSS Test I was performed on 120 controls with normosmia, 39 patients with hyposmia, and 24 patients with anosmia. KVSS Test II was performed on 117 controls with normosmia, 29 patients with hyposmia, and 22 patients with anosmia. The subjects ranged in ages from 20 to 69 years. RESULTS: In KVSS Test I, the range of scores (smell test) was 5.36-7.34 in normosmia, 3.41-6.73 in hyposmia, and 1.14-3.16 in anosmia. In KVSS Test II, the range of T.D.I. score (the sum of olfactory threshold score, odor discrimination score, and odor identification score) was 25.98-35.48 in normosmia, 17.01-30.63 in hyposmia, and 7.32-14.06 in anosmia (p<0.001). CONCLUSION: It is concluded that KVSS Test I and II are suitable for the routine clinical assessment of olfactory performance in Koreans.

PURPOSE: The purpose of this study was to demonstrate the prognostic significance of changes in body composition in patients with newly diagnosed hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Patients (n=178) newly diagnosed with HCC participated in the study between 2007 and 2012. Areas of skeletal muscle and abdominal fat were directly measured using a three-dimensional workstation. Cox proportional-hazards modes were used to estimate the effect of baseline variables on overall survival. The inverse probability of treatmentweighting (IPTW) method was used to minimize confounding bias. RESULTS: Cutoff values for sarcopenia, obtained from receiver-operating characteristic curves, were defined as skeletal muscle index at the third lumbar vertebra of ≤ 45.8 cm/m2 for males and ≤ 43.0 cm/m2 for females. Sarcopenia patients were older, more likely to be female, and had lower body mass index. Univariable analysis showed that the presence of sarcopenia and visceral to subcutaneous fat area ratio (VSR) were significantly associatedwith prognosis. The multivariable analyses revealed that VSR was predictive of overall survival. However, in the multivariable Cox model adjusted by IPTW, sarcopenia, not VSR, were associated with overall survival. CONCLUSION: The presence of sarcopenia at HCC diagnosis is independently associated with survival.

The Budd-Chiari syndrome is no longer a rare disease in the world, but there has been small cases reported until now in Korea. There are three forms of Budd-Chiari syndrome, among them membranous web in the inferior vena cava is the most common form in the oriental area. Authors have expereinced the Budd-Chiari syndrome, 49 year old female patient, caused by membranous web associated with the long thrombus in the inferior vena cava. She underwent side-to-side portacaval shunt and cavoatrial shunt using 19 mm diameter, 25 cm length polytetrafluoroetylene graft. Postoperative major morbidities were ARF and pneumonia. She has improved clinically and pathologically after operation. It is concluded that combined portacaval shunt and cavoatrial shunt has been effective to relieve the symptoms of Budd-Chiari syndrome caused by membranous web and inferior vena cava thrombotic occlusion.

Background/Aims:
A comprehensive analysis of trends in the incidence of hepatocellular carcinoma (HCC) is important for planning public health initiatives. We aimed to analyze the trends in HCC incidence in South Korea over 10 years and to predict the incidence for the year 2028.
Methods:
Data from patients with newly diagnosed HCC between 2008 and 2018 were obtained from Korean National Health Insurance Service database. Age-standardized incidence rates (ASRs) were calculated to compare HCC incidence. A poisson regression model was used to predict the future incidence of HCC.
Results:
The average crude incidence rate (CR) was 22.4 per 100,000 person-years, and the average ASR was 17.6 per 100,000 person-years between 2008 and 2018. The CR (from 23.9 to 21.2 per 100,000 person-years) and ASR (from 21.9 to 14.3 per 100,000 person-years) of HCC incidence decreased during the past ten years in all age groups, except in the elderly. The ASR of patients aged ≥80 years increased significantly (from 70.0 to 160.2/100,000 person-years; average annual percent change, +9.00%; P<0.001). The estimated CR (17.9 per 100,000 person-years) and ASR (9.7 per 100,000 person-years) of HCC incidence in 2028 was declined, but the number of HCC patients aged ≥80 years in 2028 will be quadruple greater than the number of HCC patients in 2008 (from 521 to 2,055), comprising 21.3% of all HCC patients in 2028.
Conclusions
The ASRs of HCC in Korea have gradually declined over the past 10 years, but the number, CR, and ASR are increasing in patients aged ≥80 years.

Background/Aims:
Most guidelines recommend surgical resection of all main duct (MD) and mixed-type (MT) intraductal papillary mucinous neoplasms (IPMNs) in suitable patients. However, there is little evidence regarding the malignancy risk of enhancing mural nodules (EMNs) that are present only in the main pancreatic duct (MPD) in patients with MD- and MT-IPMNs.Therefore, this study aimed to identify the clinical and morphological features associated with malignancy in MD- and MT-IPMNs with EMNs only in the MPD.
Methods:
We retrospectively enrolled 50 patients with MD- and MT-IPMNs with EMNs only in the MPD on contrast-enhanced magnetic resonance imaging. We evaluated the clinical characteristics and preoperative radiologic imaging results of MPD morphology and EMN size and analyzed the risk factors associated with malignancy.
Results:
Histological findings of EMNs were low-grade dysplasia (38%), malignant lesions (62%), high-grade dysplasia (34%), and invasive carcinoma (28%). On the receiver operating characteristic curve, the cutoff value of EMN size on magnetic resonance imaging for best predicting malignancy was 5 mm (sensitivity, 93.5%; specificity, 52.6%; area under the curve, 0.753).Multivariate analysis showed that only EMN >5 mm (odds ratio, 27.69; confidence interval, 2.75 to 278.73; p=0.050) was an independent risk factor for malignancy.
Conclusions
EMNs of >5 mm are associated with malignancy in patients with MD- and MTIPMNs with EMNs that are present only in the MPD, in accordance with the international consensus guidelines.
