The European Association for the Study of the Liver (EASL) in 2001 and the American Association for Liver Diseases (AASLD) in 2005 followed the Barcelona - Clinic Liver Cancer (BCLC) staging classification and treatment schedule. Surgical resection can be offered for patients who have a single lesion if they are not cirrhotic or have cirrhosis and still have well-preserved liver function, normal bilirubin and hepatic vein pressure <10 mmHg (level II). But the Japanese Practice Guideline reported by the Japanese Society of Hepatology in 2007 recommended surgical resection for 2 or 3 tumors no more than 3 cm in diameter, even in cases with 4 or more lesions. The differences in practice guidelines between these two areas come from different cultural situations, especially in the availability of transplantation. Our results from hepatic resection in 834 patients with HCC from 1992 to 2004 at Seoul National University Hospital were as follows: 1) After surgical resection, the favorable prognostic group are patients with tumor size less than 10 cm in size without major vessel invasion. 2) Surgical resection is recommended in the favorable group of patients with oligonodular tumors. 3) Surgical resection is not indicated for patients with major vessel tumor invasion or portal hypertension. In the AASLD guidelines, liver transplantation is an effective option for patients with HCC, corresponding to the Milan criteria: solitary <5 cm or up to three nodules <3 cm (level II), and a living donor transplantation can be offered for HCC if the waiting time is long enough to allow tumor progression leading to exclusion from the waiting list (level II). Japanese Practice Guidelines restrict liver transplantation to patients under the age of 65. The role of salvage liver transplantation is still controversial. Early detection and the development of therapeutic agents for metastases by microvascular tumor invasion are important for increasing survival of HCC patients.

Purpose: Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy, but outcome studies are uncommon. The purpose of this study was to determine outcomes and prognostic factors after surgical resection. Methods: We reviewed and analyzed retrospectively fifty four patients who were diagnosed as having intrahepatic cholangiocarcinoma and whose tumor was resected surgically between 2001 and 2009. Our analysis focused on survival and on significant prognostic factors affecting survival after surgical resection. Results: Forty-one subjects (75.9%) were male and twelve (24.1%) were female. The average age was 59.4 years old. For predisposing factors, infestation of clonorchis sinensis plus hepatitis B antigen positivity were 11.1% respectively. Among tumor markers, CA 19-9 was elevated in 50.9% and CEA in 30%. Eighty percent were treated by major hepatectomy. Overall 3 & 5 year-survival rates were 41.8% and 36.2%, and 3 and 5 year disease free survival rates were 37.5% and 28.6%, respectively. By univariate analysis, significant prognostic factors affecting cumulative survival were tumor size, vascular invasion, tumor differentiation, serosal invasion, metastasis to the regional lymph nodes and tumor markers CEA and CA 19-9. By multivariate analysis, only differentiation and metastasis to the lymph nodes were significant. Conclusion: The prognosis of intrahepatic cholangiocarcinoma is poor but has been improved by curative surgical resection. Tumor factors, tumor differentiation and lymph node metastasis were elucidated as the most significant prognostic factors, and radical surgical resection is the only way to get a better outcome from IHC that has a notoriously poor prognosis.

Purpose: The aim of this study was to present our experience before establishing laparoscopic left lateral sectionectomy (LLLS) of the liver as a standard procedure, and to show efficacy of a totally LLLS compared to an open left lateral sectionectomy (OLLS). Methods: We retrospectively analyzed and compared clinical outcomes (operation time, blood loss, hospital stay, complication rate, etc) for 29 patients who underwent LLLS and 27 patients who underwent OLLS between January, 2002 and December, 2009. To see the learning curve for LLLS, we arbitrarily divided the LLLSs we did into an early group (ELLLS) and a late group (LLLLS) based on when they were operated on relative to case number 14. Results: Mean operative times for the ELLLS, LLLLS and OLLS groups were 269.7
${\pm}$ 102.6, 210.0${\pm}$ 47.9 and 289.1${\pm}$ 72.8 minutes, respectively. Mean operative time was significantly shorter (p<0.05) in the LLLLS than the OLLS group. Mean intra-operative blood loss was also less in the LLLLS group than the OLLS group (80.00${\pm}$ 224.2 ml vs. 195.15${\pm}$ 405.4 ml). Post-operative hospital stay was shorter in the LLLLS group than the OLLS group (9.9${\pm}$ 4.0 versus 16.9${\pm}$ 9.1, p=0.071). Conclusion: The totally LLLS is a safe, feasible treatment option that can be a standard procedure with better outcomes in selected patients after an initial learning curve. -

Purpose: This study was designed to compare outcomes in patients who underwent hepatectomy or radiofrequency thermal ablation (RFA) for synchronous or metachronous colorectal liver metastases (CLM). Methods: One hundred twenty-two patients who underwent hepatectomy or RFA for their first CLM between 2001 and 2004 were enrolled in this study. The patients were divided into two groups (synchronous [N=77] and metachronous [N=45] CLM). Patient characteristics, clinicopathologic features, long-term outcomes, and prognostic factors were analyzed retrospectively. Results: There were no significant differences in the 5-year disease-free and overall survival rates between the synchronous and metachronous CLM groups (36.2% vs. 37.2%, p=0.78; and 53.0% vs. 54.4%, p=0.82, respectively). Patients in the synchronous CLM group underwent more bilobar hepatic resections, intra-operative RFA, or co-modality treatments than the metachronous CLM group (p=0.035). The surgical resection group had a longer disease-free survival, but not overall survival than the RFA group. Greater N stage and female gender were associated with a worse prognosis in overall survival; N0 stage and surgical resection were good prognostic factors for disease-free survival. N stage and surgical resection were also statistically significant prognostic factors based on multivariate analysis. Conclusion: The synchronicity of CLM is not a significant prognostic factor, but the clinicopathologic characteristics that reflect more disseminated disease than metachronous metastasis are significant prognostic factors. Tumor characteristics and aggressiveness may be more important for prognosis than chronology. -
Purpose: Surgery remains the only curative option for patients with extrahepatic bile duct cancer (EHBD Ca). But, long-term survival is typically not good because of the advanced stage of disease at the time of diagnosis and frequent disease recurrence after surgical resection. The purpose of this study was to evaluate factors that influence survival and recurrence after surgical resection of EHBD Ca. Methods: A retrospective analysis of 113 patients who had received surgical resection for EHBD Ca between 2004 and 2009 was done. We investigated histopathological features, and survival and recurrence rates, and evaluated prognostic factors affecting survival and disease recurrence after surgical resection. Results: Overall survival rates for 1, 3 and 5 years were 73.2%, 42.8%, and 36.0% respectively. In univariate analysis, prognostic factors influencing survival were histologic differentiation, T stage, lymph node (LN) metastasis, TNM stage, perineural invasion (PNI), lymphovascular invasion (LVI) and resection margin state. Among them, LN metastasis, PNI and resection margin state were found to be independent prognostic factors for overall survival in multivariate analysis. Recurrence occurred in 44 patients (48.9%) and disease-free survival rates were 50.6% at 1 year and 38.3% at 3 year. Univariate analysis revealed that histologic differentiation, T stage, LN metastasis, TNM stage, PNI and LVI were significantly associated with recurrence. In multivariate analysis, only LN metastasis was found to be a significant independent predictor of recurrence. Conclusion: LN metastasis, PNI and positive resection margin were significant prognostic factors affecting survival. LN metastasis was found to be a significant independent predictor of recurrence in surgical resection of EHBD Ca.

Purpose: Recent findings indicate that after cholecystectomy for early gallbladder cancer (GBC), outcomes are generally satisfactory. But outcomes for advanced GBC are dismal, even with recent advances in diagnostic and therapeutic modalities. The purpose of this study was to evaluate surgical outcomes and prognostic factors affecting survival after surgical resection in patients with GBC. Methods: We retrospectively reviewed clinical data from 133 patients with GBC who underwent surgical resection between January 2000 and December 2008. Their clinical condition, surgical treatment, and pathologic factors were analyzed. Results: Among the 133 patients with GBC, curative resection was achieved in 95 (71.4%). The 5-year survival rate in patients who underwent curative resection (52.6%) was much better than in those who underwent palliative resection (0.0%, p<0.000). Univariate analysis revealed that the following factors were associated with patient survival: preoperative jaundice, pain at presentation, incidental GBC, serum total bilirubin, alkaline phosphatase (ALP), carbohydrate antigen 19-9 levels, curability, lymph node (LN) dissection, size, site, macroscopic type of tumor, histologic differentiation, the depth of tumor invasion (T stage), LN metastasis, TNM stage and microscopic perineural invasion. Multivariate analysis revealed that the following were independent, favorable prognostic factors: curative resection, no LN metastasis, low TNM stage, non-papillary macroscopic type, and low ALP levels. Conclusion: Complete tumor resection and no LN metastasis are important prognostic factors for GBC. Favorable survival outcomes can be achieved when curative resection is done in early stage GBC and when operative procedures are planned with the consideration of the survival benefit of surgery in advanced GBC.

Purpose: The purpose of this study was to evaluate the clinical benefits of preoperative percutaneous transhepatic drainage (PTGBD), especially regarding morbidity and mortality, in patients aged 60 or older with acute cholecystitis. Methods: A retrospective study was done on a series of elderly patients (>60 years old; n=132) who had been diagnosed between January 2007 and December 2009 as having acute cholecystitis. The patients were divided into 4 groups; cases in which only laparoscopic cholecystectomy (LC) was done (Group 1, n=84), cases in which LC was done after preoperative PTGBD (Group 2, n=15), cases in which only open cholecystectomy was done (Group 3, n=23), and cases in which open cholecystectomy was done after preoperative PTGBD (Group 4, n=10). We analyzed between group differences in surgical outcomes including periods of postoperative fast and postoperative hospital stay, OP. morbidity, and open conversion rate. Results: Patients in Group 1 had fewer underlying medical problems and lower ASA scores than patients in groups 2, 3, or 4 (p<0.05). Mean operating time in Group 2 (113.66
${\pm}$ 107.5 min) was significantly longer than in group 1 (72.02.9${\pm}$ 34.2 min) (p<0.05) and the open conversion rate was higher (8.33% vs 26.67%). But, blood loss (ml) and OP time in Group 2 were lower than in Group 3 or 4 (p<0.001). Postoperative recovery progression (periods of postoperative fasting and length of postoperative hospital stay) of Group 2 were better than in groups 3 or 4 (p<0.001). Conclusion: Pre-operative PTGBD procedures in elderly patients with acute cholecystitis is a good clinical option as a pretreatment to a cholecystitis operation. -

Purpose: To evaluate treatment outcomes for patients with stage II/III pancreatic cancer who are treated with radiation therapy (RT) with or without chemotherapy (CTx) following surgery. Methods: We retrospectively analyzed data from 17 patients who underwent surgery and post-operative RT with or without CTx between January 2000 and December 2008. Seven patients (41%) had stage II cancer and 10 (59%) had stage III cancer. Most were male (13 of 17; 76.5%). Age at diagnosis ranged from 42 to 82 (median 69) years. Whipple's operation was done in 9 patients (53%), distal pancreatectomy in 7 (41%), and subtotal pancreatectomy in 1 (6%). All patients received RT using a three-dimensional RT technique to spare critical normal structures. Median radiation dose was 54 Gy (range, 50.4~55.8 Gy). Variable CTx regimens were combined in 10 patients (58.8%); 5-FU in 4, UFTE-G in 4, gemcitabine in 1, and xeloda in 1. Acute toxicity was evaluated according to RTOG toxicity criteria. Survival analysis was done using the Kaplan-Meyer method. Univariate and multivariate prognostic factor analysis were done, respectively, using a log-rank test and Cox's proportional hazards model. Results: The median follow-up period was 12.6 months. Locoregional and distant failures occurred in 8 (47.1%) and 8 patients (47.1%), respectively. Five patients (29.4%) developed both loco-regional recurrence and distant metastasis. The metastatic sites were liver in 4 patients, lung in 3, peritoneum in 1, and kidney in 1. Median overall survival (OS) was 12.6 months. The 1- and 2-year OS rates were, respectively, 58.8% and 24.5%. Median disease-free survival (DFS) was 8.3 months and the 1- and 2-year DFS rates were 46.3% and 30.9%, respectively. The 2-year OS was not different between RT and RT with CTx : survival rates were 28.6% and 17.5%, respectively (p=0.764). T stage and a postoperative CA 19-9 level of${\geq}$ 180 U/ml were significant prognostic factors for OS in both univariate and multivariate analysis: the 2-year OS for T3 and T4 were 34.1% and 16.7%, respectively (p=0.0022), the 2-year OS for <180 and${\geq}$ 180 U/ml were 32.5% and 0%, respectively (p=0.0142) Acute toxicities were RTOG grade 1 (G1) nausea in 1 patient (5.9%), G1 vomiting in 2 (11.8%), and G1-2 enteritis in 5 (29.4%). The hematologic toxicities were G1 leukopenia in 5 patients (29.4%), G2 leukopenia 1 (5.9%), G1 thrombocytopenia in 1 (5.9%), and G1~2 anemia in 6 (35.3%). Conclusion: Survival results of the present study are comparable to those in other reports with acceptable toxicity. Significant prognostic factors for overall survival in pancreatic cancer are tumor stage and postoperative CA 19-9 level. -
Purpose: Clinical features of Pancreatic Neuroendocrine Tumors (PETs) vary according to the hormone secreted and to the heredity of the tumors. Malignant PETs are common among nonfunctioning PETs (NFTs) whereas the majority of functioning PETs (FTs) are benign. Our goal was to determine the clinical features and prognosis of PETs stratified by the WHO classification scheme and AJCC-UICC
$7^{TH}$ TNM staging. Methods: We selected for study 30 patients with PETs, including one case of nesidiolastosis, who presented at our clinic between April 1992 and June 2010. Clinicopathological features were studied retrospectively. PETs were classified as benign, uncertain malignant, well differentiated carcinoma, or poorly differentiated carcinomas by the WHO classification. For statistical analysis, Student's t-test, the Chi-square test, and the Kaplan-Meier method were utilized. Results: Nine cases were FTs and twenty one cases were NFTs. The average size of the FTs was smaller than that of the NFTs (1.71 vs 4.33, p=0.04). The head of the pancreas was most commonly involved (33.3% of FTs; 47.6% of NFTs) but the locations of the tumors were not different. Insulinoma was the most common (66.7%, 6/9) among FTs. The incidence of malignant tumors was 33.3% and 55.0% among, respectively, FTs and NFTs. The 5-year disease-free survival rate of patients with benign PETs (FTs and NFTs), and of patients with functioning well-differentiated carcinomas was 100%. However, the 5-year disease-free survival rates of patients with nonfunctioning well- and poorly-differentiated carcinomas were 66.7% and 0%. Conclusion: Among patients with Pancreatic Neuroendocrine Tumors, malignant tumors are more common among NFTs than FTs. Poorly-differentiated carcinomas have a worse prognosis while all FTs regardless of their WHO classification fail to show any disease recurrence. -
Annular pancreas is a rare congenital anomaly that consists of a ring of pancreatic tissue partially or completely encircling the descending portion of the duodenum. Coexisting ampullary carcinoma in annular pancreas combined with anomaly of hepatic artery or bile duct are thought to be extremely rare. Two consecutive cases of ampullary carcinoma in annular pancreas with bile duct or hepatic artery anomaly are described. In addition, English literature reports of coexisting ampullary carcinoma in annular pancreas are summarized. Clinical symptoms of the two patients were jaundice and abdominal discomfort. The two ampullary cancers were early adenocarcinomas in the ampulla of Vater that were curatively treated by pylorus preserving pancreaticoduodenectomy. Ampullary carcinoma associated with annular pancreas is rare. Its combination with an additional biliary or hepatic artery anomaly make our cases extremely unique. Certain aberrant events in the overall stages of the development of the liver, bile duct, and pancreas may have occurred in these patients. Surgeons need to note preoperatively these possible associated anatomic variations.

Protein S (PS) deficiency is a rare blood disorder associated with thrombosis. Only a small number of cases of isolated celiac artery dissection can be found in the literature. We now report a case of isolated celiac artery dissection and splenic infarction in a 44-year old male with PS deficiency. Abdominal computed tomography revealed celiac artery dissection and splenic infarction. The patient's PS activity was 64% (nl : 70~140%) upon admission and 52% four weeks later. He was started on a regimen of NPO, antibiotics, and analgesics. He resumed oral intake of food and drugs on hospital day 3 and was discharged to his home on hospital day 8. We report a case of isolated celiac artery dissection with splenic infarction in a patient with PS deficiency that improved with conservative treatment. The patient's management did not include anti-platelet/thrombotic agents or endovascular/operational procedures.
