RESUMEN
Purpose@#We aimed to assess local tumor progression (LTP) rate and associated prognostic factors in 92 patients who underwent radiofrequency ablation (RFA) using saline-perfused electrodes to treat hepatocellular carcinoma (HCC) (≤ 5 cm). @*Materials and Methods@#Total 92 patients with 148 HCCs were treated with RFA using salineperfused electrodes, from 2009 to 2015. We retrospectively evaluated technical success, technique efficacy, and LTP rates. Potential prognostic factors for LTP were perivascular tumor, subphrenic tumor, artificial ascites, tumor size (≥ 2 cm), and previous treatment of transarterial chemoembolization. Analysis was performed by lesion, rather than by person. @*Results@#During follow-up period from 1 to 97.4 months, total cumulative LTP rates were 7.9%, 11.4%, and 14.6% at 1, 3, and 5 years, respectively. These values were significantly higher in the perivascular (35.1%; p = 0.009) and subphrenic group (38.9%; p = 0.002) at 5-year. We did not observe any significant difference in LTP according to other prognostic factors (p > 0.05). @*Conclusion@#RFA with saline-perfused electrode is a safe and effective treatment modality for HCC (≤ 5 cm), with lower LTP rates. Nevertheless, perivascular and subphrenic HCCs demonstrated higher LTP rate than other sites. It is imperative to note that perivascular and subphrenic location of HCC are associated with a high risk of local recurrence, despite the use of salineperfused electrodes.
RESUMEN
BACKGROUND/AIMS: The exclusion of hepatitis B core antibody (HBcAb)-positive donors from liver transplants (LTs) due to the risk of transmitting hepatitis B virus (HBV) does not appear to be practical in Korea, where hepatitis B is endemic. This study assessed the risk of de novo HBV infection in hepatitis B surface antigen (HBsAg)-negative LT recipients receiving a liver from HBcAb-positive donors. METHODS: Of 341 adult living donor LTs conducted at our institution between March 2001 and September 2008, 176 donors (51.6%) were HBcAb-positive, and 26 HBcAb-positive grafts were transplanted to HBsAg-negative recipients. The median follow-up time after LT was 41.9 months. RESULTS: Without anti-HBV prophylaxis, 2 out of 26 (7.7%) HBsAg-negative recipients who received grafts from HBcAb-positive donors developed de novo HBV infection 20 and 85 months after LT. These patients had been negative for all HBV serologic markers before transplantation. In both cases, there were no abnormalities in liver function tests upon diagnosis of de novo HBV infection. CONCLUSIONS: De novo HBV infection from HBcAb-positive donors after LT does not appear to be of great concern in terms of the number of cases in Korea because high risk patients who are HBV-negative comprise only a small proportion of the recipients. However, HBV-naive LT recipients still carry the risk of developing de novo HBV infection as in non-HBV endemic areas.

The inverse correlation of appendectomy and ulcerative colitis is well known, but the effect of appendectomy on the clinical course of ulcerative colitis remains unclear. Although the majority of opinions were negative for the therapeutic advantage of appendectomy in patients with ulcerative colitis, advocates for positive effect of appendectomy have been proposed in a few case reports and a prospective study from Western countries. We herein report a case of ulcerative colitis who experienced clinical remission after appendectomy for acute appendicitis. The patient was 35 year old male and had been managed with immunosuppressant before appendectomy. The very acute change in clinical course and a long period of remission after appendectomy highly suggest the therapeutic effect of appendectomy for ulcerative colitis.

An 84 yr-old male with a history of nausea and vomiting for 3 weeks was admitted to our hospital. Esopahgogastroduodenoscopy showed the diffuse infiltrative type of gastric cancer encircling from the cardia to the lower body. On abdominal computerized tomography, the gastric wall was diffusely thickened with overlying mucosal enhancement without lymph node involvement. Histologic examination revealed poorly differentiated adenocarcinoma. So surgical resection was planned. However, patient refused all medical care, and then he was discharged. He lived without any medical support and then he revisited our hospital and showed relieved symptoms on the follow-up exam. On esophagogastroduodenoscopy, the gastric mucosa of the body looked normal without any dysplastic change. Abdominal CT revealed a decreased thickening of the gastric wall of the body. The histology from the endoscopic forceps biopsy showed no evidence of malignancy. The patient is alive without any sign of tumor recurrence after 14 months.

A 70-yr-old woman complained of left sided chest pain and non-bilious vomiting for four days after taking a gastric bloating agent for an upper gastrointestinal study. The chest radiography revealed gastric air-fluid levels and bowel loops in the left thoracic cavity. An emergency thoracotomy was performed. The abdominal organs (stomach, spleen, splenic flexure of the colon) were in the left thorax and the entire left hemidiaphragm was absent. There were no diaphragmatic remnants visible for reconstruction of the left diaphragm. We provided warm saline irrigation and performed a left lower lobe adhesiotomy. Thirteen days after surgery, the chest radiography showed improvement in the herniation but mild haziness remained at the left lower lung field. Here we present the oldest case of congenital diaphragmatic agenesis presenting with transient gastric volvulus and diaphragmatic hernia.

BACKGROUND/AIMS: This study examined the effects of hepatitis B virus (HBV) infection state and immunologic capability in both the recipients and donors of allogenic hematopoietic stem-cell transplantation (allo-HSCT) on changes in HBV serologic markers in recipients. METHODS: A total of 537 patients underwent allo-HSCT for the treatment of leukemia, malignant lymphoma, and solid tumor. HBV serologic markers were examined in both recipients and donors prior to and following the transplantation. The mean follow-up period was 36.6 months (range 3-80 months). RESULTS: Of the 537 patients who underwent allo-HSCT, 45 recipients were positive for HBsAg prior to transplantation. Of these 45 patients, 21 were transplanted from anti-HBs-positive donors and the remaining 24 were transplanted from anti-HBs-negative donors. In the former cases, seroconversion was noted in 4 of the 21 patients (19%). In the latter cases, however, no seroconversion was noted following the transplantation. Thirty patients who were negative for both HBsAg and anti-HBs were transplanted from anti-HBs-positive donors, and 15 out of 30 patients (50%) acquired anti-HBs. Four hundred and seven patients who were positive for anti-HBs were transplanted from anti-HBs-positive or HbsAg-negative donors; 8 of these proved HBsAg-positive following the transplantation. There were no changes in HBV serological markers following transplantation in 41 patients who were transplanted from HbsAg-positive donors. CONCLUSIONS: Due to the adoptive immunity that was transferred from anti-HBs-positive donors, a seroconversion of HBsAg could occur in some HBsAg-positive recipients. HBsAg-positive donors had a lesser effect on the HBV serologic markers of recipients. However, a reactivation of HBV can occur following hematopoietic stem-cell transplantation in the cases of recipients or donors with a history of HBV, infection by an accompanying immune suppression. Therefore, prevention should be instigated.

BACKGROUND/AIMS: CT colonography is a rapid and safe imaging method for detecting polyps in the colon and rectum. We assessed the efficacy of CT colonography in colorectal polyp detection. METHODS: We prospectively studied 84 subjects (mean age 55.7+/-11.1 years; 52 men, 32 women) undergoing CT colonography followed by colonoscopy. Based on the results of CT colonography, all polyps were classified by size (any size, and those larger than 5, 7, and 10 mm) and were checked for location, morphology, and histological characteristics. We determined the sensitivity and specificity of CT colonography using colonoscopy as a reference standard with a segmental unblinding method. RESULTS: A total of 56 lesions were identified in 26 of 79 subjects undergoing both CT colonography and conventional colonoscopy. The sensitivities of CT colonography for polyps of any size, and larger than 5, 7, and 10 mm were 60.7%, 70.5%, 75.9%, and 81.8%, respectively. The per-subject sensitivities of CT colonography for the polyps of any size, and larger than 5, 7, and 10 mm, were 80.7%, 95.0%, 93.3%, and 90.9%, respectively. The per-subject specificities of CT colonography for polyps were 86.8%, 89.8%, 95.3%, and 100.0%, respectively. The sensitivities of CT colonography for flat, sessile, and pedunculated polyps were 30.8%, 85.0%, and 90.0%, respectively. CONCLUSIONS: CT colonography is a useful diagnostic method for screening colorectal neoplasias larger than 7 mm diameter, showing 75.9% sensitivity and 71.0% positive predictive value.

PURPOSE: We wanted to evaluate the levels of effect and safety of high-intensity focused ultrasound ablation (HIFU) for treating patients with advanced pancreatic cancer. MATERIALS AND METHODS: Nineteen sessions of HIFU, with the patients under general anesthesia, were performed in 18 patients with advanced pancreatic cancer. The change of the gray-scale of the target lesion was analyzed during HIFU, and MRI was performed before and after HIFU. We assessed the extent of coagulative necrosis, the change of pain and the complications after HIFU. The change of tumor size and the survival of patients were also evaluated. RESULTS: The average size of tumor was 4 cm in diameter. Eighty nine percent of the target tumors showed increased echogenicity. On MRI, necrosis of the entire target tumor occurred in 79% of the patients. After treatment, effective pain relief was noted in 89% of the patients. There were no major complications. No size increase of the treated tumor was noted during 24 weeks of follow-up for 10 patients. Six patients among 12 patients who were available for follow-up are still alive and they are receiving chemotherapy. Six patients expired due to other disease or progression of metastasis. CONCLUSION: HIFU is a safe method without any major complications, and it is effective for inducing tumor necrosis and achieving pain control for patients with advanced pancreatic cancer.

BACKGROUND/AIMS: Hepatic nerve innervation plays important roles in hepatic metabolism and hemodynamic mechanisms. We compared the distribution patterns of hepatic nerves between normal livers and two liver diseases to elucidate the effects of liver disease on the distribution of hepatic nerves. METHODS: Tissue specimens were obtained by ultrasonography-guided needle biopsies from 10 normal controls, 74 patients with chronic hepatitis (CH), and 35 patients with liver cirrhosis (LC). The obtained specimens were immunohistochemically stained using antibodies for S-100 protein and alpha-smooth-muscle actin (alpha-SMA). The degree of the expression in liver tissues was quantified by manual counting of positively stained nerve fibers under light microscopy. The serum hyaluronic acid level was assayed in all subjects to evaluate hepatic fibrosis. Electron microscopy examinations were also performed. RESULTS: The hepatic nerve innervation was significantly lower in LC than in normal controls, as indicated by S-100 protein staining. alpha-SMA and hyaluronic acid levels were higher in LC and CH than in normal controls. Electron microscopy revealed that unmyelinated nerve fiber bundles in the intralobar connective tissue coursed in the vicinity of hepatic triads. CONCLUSIONS: These results suggest that hepatic nerve innervation can be decreased by hepatic inflammatory responses and/or fibrotic changes in LC patients. Further study is needed to clarify this observation.

BACKGROUND: The purpose of this study was to evaluate the association of physical distress and mental health characteristics with the willingness to repeat an esophagogastroduodenoscopic (EGD) examination. METHODS: A questionnaire survey was conducted on 137 patients who had an EGD procedure. The mental health status was evaluated with the Checklist-90-Revision tool, which is based on the Multidimensional Self Report Symptom Inventory. RESULTS: The results were as follows. 1) The elderly and those patients with two or more procedures had a significantly higher willingness to repeat the EGD examination. Those who were willing to repeat the examination had more EGD examinations than those who did not (p<0.05). 2) As for the mental health characteristics, persons with a willingness to repeat the EGD examination showed significantly lower scores on the interpersonal, sensitivity, depression, anxiety, hostility, and paranoid ideation than did those without a willingness. 3) As for the degree of physical distress during the EGD examination, persons with a willingness to repeat the EGD examination had significantly lower scores on the total symptom score and global discomfort score than those without a willingness (p<0.05). 4) The younger patients, under 30, had a significantly lower willingness to repeat the EGD examination than did the elderly patients over 60 (OR=86.03, 95% CI 2.11-999). According to patient occupations, homemakers showed a significantly higher willingness than did others (OR=16.24, 95% CI 1.69-156.23). CONCLUSIONS: The results of this study suggested that a willingness to repeat the EGD examination was closely associated with the mental health characteristics of the patients.

BACKGROUND: Spontaneous delayed clearance of hepatitis B surface antigen (HBsAg) in patients with chronic HBV infection is a rare event. The aim of this study was to investigate the incidence of delayed clearance of serum HBsAg in chronic HBV infection and to determine the characteristics and clinical outcomes of HBsAg delayed clearance in Korean patients. METHODS: From April 1981 to June 2003, 4,061 patients who were positive for HBsAg were evaluated retrospectively. The following assessments were undertaken in 47 patients who had spontaneous delayed clearance: liver biochemistry, viral markers, alpha-fetoprotein levels, and radiographic examinations including ultrasonography every three to six months for 6-264 months (median 87.9 months). RESULTS: Twenty-four of 47 patients were asymptomatic carriers. The others included seven patients with chronic hepatitis, seven with liver cirrhosis and nine with hepatocellular carcinoma. The estimated annual incidence of HBsAg seroclearance was 0.4%. The time span from positive HBsAg to HBsAg seroclearance in the AHC, CH, LC, and HCC was 62.9, 141, 63, and 95.3 months during follow up. Twenty-four of 24 AHC remained normal, 5 of 7 CH remained as CH and 2 patients remained normal, 1 of 7 with LC developed HCC and 6 of the LC remained as LC, and 4 of 9 HCC patients died. CONCLUSION: The clinical course following delayed clearance of HBsAg had diverse outcomes from AHC to HCC. Therefore, these patients require close follow up for the possible development of hepatocellular carcinoma following HBsAg clearance.

Nonrotation of the intestine is a rare disorder mostly found in childhood. During adult life, nonrotation of the intestine is found either during surgery or during the evaluation of unrelated symptoms. A preduodenal portal vein is also a rare anomaly. These anomalies are associated with situs inversus, and duodenal, pancreatic, biliary and cardiovascular anomalies. A 21-year-old man presented with mild constipation. During the evaluation, we found multiple intraabdominal anomalies, including nonrotation of the intestine, a preduodenal portal vein, polysplenia, and an annular and short pancreas.

BACKGROUND AND AIMS: Telbivudine is an L-nucleoside analogue with potent antiviral activity against hepatitis B virus (HBV). Clinical trials have shown that telbivudine is more potent than lamivudine for suppressing virus. METHODS: A total 101 Korean patients among 1,367 patients who participated in the phase III GLOBE trial were randomized in this study. All 101 HBeAg positive or HBeAg negative patients were assigned to treatment with 600 mg of telbivudine or 100 mg of lamivudine once daily. The primary efficacy endpoint (the "therapeutic response") was defined as suppression of the serum HBV DNA to less than 5 log10 copies/mL coupled with either normalization of the serum alanine aminotransferase level or loss of HBeAg. The secondary endpoints included the histologic response, serum HBV DNA reduction, serum alanine aminotransferase normalization and HBeAg loss for the HBeAg positive patients. This analysis includes the data collected at 52 weeks of treatment. RESULTS: Fifty four of 101 patients were assigned to telbivudine treatment and 47 patients were assigned to lamivudine treatment. At week 52, significantly more patients who were treated with telbivudine than those treated with lamivudine had a therapeutic response (83% vs 62%, respectively, P=0.017), their mean serum HBV DNA levels were more reduced (6.6 vs 5.6 log10 copies/mL, respectively, P=0.027), and they more often achieved PCR-undetectable levels of serum HBV DNA (74% vs 34%, P<0.0001). No virologic resistance to telbivudine was detected (0% vs 18%, respectively, P=0.001). Telbivudine was well tolerated and it had a safety profile comparable to lamivudine. CONCLUSIONS: Patients treated with telbivudine achieved earlier and more profound viral suppression than those treated with lamivudine.

Portal and mesenteric venous thrombosis is an uncommon disease, but clinically important, because it accounts for 5% to 15% of acute mesenteric ischemia. The diagnosis is often delayed because the conditions are nonspecific abdominal symptoms. In addition, when this occurs in young individual without any known predisposing factor, the diagnosis may become even more difficult. The treatment of mesenteric venous thrombosis involves anticoagulation therapy alone or in combination with surgery. The addition of thrombolytic therapy to the treatment of portal and mesenteric venous thrombosis may enhance the clearance of thrombus and hasten the clinical improvements. We present a case of mesenteric venous thrombosis treated with catheter-directed infusion of urokinase via the superior mesenteric artery and systemic anticoagulation.

Neoplasms of the stomach can originate from both epithelial and subepithelial cells. These two types of tumors have different morphological characteristics according to their origin including the mucosal surface texture and contour of the mass in endoscopic examination. However, on rare occasions, neoplasms of an epithelial origin manifest the features of a submucosal tumor on a gross examination, and require additional and more invasive approaches, such as a strip biopsy, computed tomography, and endosonography, to define their nature. We encountered a case of a gastric adenocarcinoma in a 44 year-old woman, which was initially considered to be submucosal tumor by the endoscopic examination and was finally diagnosed after resecting the tumor.

BACKGROUND/AIMS: Apoptosis via Fas/FasL system is thought to be involved in the development of hepatocyte death in viral hepatitis B. In chronic hepatitis C, sFas/sFasL system was reported to control liver injury induced by Fas/FasL mediated apoptosis. To determine the role of sFas/sFasL system in chronic hepatitis B, we analyzed serum sFas/sFasL in 58 HBV patients and 29 healthy controls. METHODS: HBV patients were categorized into two groups; normal ALT (40 IU/L). Serum sFas/sFasL levels in HBV patients were measured by ELISA and was compared with those in 29 healthy controls. Serum ALT levels, histological activity, and Fas/FasL expression of liver were compared. RESULTS: Chronic hepatitis B patients with elevated ALT had significantly higher serum sFas levels than those in healthy controls (P<0.01). Serum sFasL levels, however, were significantly lower than those in healthy controls (P<0.01). Patients with moderate to marked degree of inflammation and fibrosis had significantly higher serum sFas levels than those in healthy controls (P<0.05). Serum sFasL levels had no correlation with the hepatic histological activity. Serum sFas/sFasL levels also had no significant correlation with the Fas/FasL expression of liver. CONCLUSIONS: Serum sFas/sFasL levels play a possible role in the pathogenesis of chronic hepatitis B. These results suggest that serum sFas levels might serve as a marker for estimating the degree of hepatic histological activity.

Hepatoid carcinoma is a primary extrahepatic neoplasm exhibiting features of hepatocellular carcinoma (HCC) in terms of morphology, immunohistochemistry, and behavior. In many cases, tumor cytoplasm is positive for alpha- fetoprotein (alpha-FP) with elevated serum alpha-FP level. Because not all hepatoid carcinomas are associated with alpha- FP overproduction, diagnosis should be made essentially by histological features of the tumor. We present a case of hepatoid carcinoma of the pancreas in a 21-year-old male patient. Abdominal computed tomography and magnetic resonance imaging revealed an inhomogeneously enhanced pancreatic head mass. Serum alpha-FP level was markedly elevated. He underwent pylorus-preserving Whipple's operation. The tumor showed hepatoid and neuroendocrine components simultaneously. The histopathological diagnosis was hepatoid carcinoma associated with neuroendocrine tumor of the pancreas. Seven months after the surgery, the patient is healthy without evidence of recurrence. To date, only 7 cases of hepatoid carcinoma of the pancreas have been reported in the literature, and this is the first case report in Korea.

Internal hernia is defined as the herniation of viscera through an anatomic or pathologic opening within the boundaries of peritoneal cavity. Transmesocolic hernia, a subtype of internal hernia, has a herniated sac through the transverse mesocolon. Transmesocolic hernia has been rarely described in the literature, and most of reported cases were associated with a history of operation or congenital anormaly. A 72-year-old female with chronic intermittent abdominal pain and bloating was admitted. Small bowel series showed multiple jejunal loops confined to the left upper quadrant of abdomen. Abdomen spiral computed tomography (CT) showed a cluster of mildly dilated small bowel loops with mesenteries on the same area. On the three-dimensional reconstruction CT scan, a herniated sac through the transverse mesocolon was identified. She was diagnosed as transmesocolic hernia by using the three-dimensional reconstruction CT and small bowel series, without surgical exploration. The symptoms were managed with conservative measures.

BACKGROUND: Most patients with hepatic encephalopathy have their protein intake restricted. Therefore, protein-calorie malnutrition becomes more severe and may cause more serious problems, such as infection and poor prognosis. The aim of this study is to determine better biochemical parameters for the assessment of nutritional status in patients with hepatic encephalopathy. METHODS: A total 109 patients (30 normal controls and 79 chronic hepatitis B) were enrolled. 79 patients were divided into three groups: chronic HBV infection (hepatitis group, n=28), liver cirrhosis without past history of hepatic encephalopathy (cirrhosis group, n=27), liver cirrhosis with present or past history of hepatic encephalopathy (encephalopathy group, n=24). Serum albumin, total lymphocyte count, IGF-1, growth hormone, retinol binding protein, leptin and fibronectin were measured. RESULTS: Serum albumin level, total lymphocyte count, IGF-1, and growth hormone were significantly lower in encephalopathy group than other groups (p<0.001, p=0.003, p<0.001, and p<0.001, respectively). However, RBP, leptin, and fibronectin were not different among the groups. The level of serum albumin and IGF-1 were significantly lower in encephalopathy group than cirrhosis group (p=0.002, p<0.001, respectively), but growth hormone was not significantly different between cirrhosis group and encephalopathy group. CONCLUSIONS: The level of serum albumin and IGF-1 may be important parameter for nutritional support in chronic liver disease, especially in patients with hepatic encephalopathy, because the level of serum albumin and IGF-1 relate with hepatic encephalopathy as well as reflect the progression of chronic liver disease.
