This study was performed to evlauate the usefulness of red ginseng extract as an adjuvant therapeutic agent to improve immune function in immune compromizing gastrointestinal carcinoma patients. We treated 48 patients with two regimens after we undertook the curative resection for gastrointestinal carcinoma: 1) only chemotherapy and immunotherapy (control group), 2) chemotherapy and immunotherapy with 4500-5400mg red ginseng for 6 months (study group). For investigating the immunologic alternations alongside the numerical changes in peripheral blood lymphocyte and their subsets in the gastrointestinal carcinoma patients, lymphocyte surface markers were determined by monoclonal antibodies on the preoperative 1st day, and postoperative 5th day, 1 month, 3 month and 6 month in 28 controls and 20 red ginseng groups in gastrointestinal carcinoma patients which were recruited at Korea University Hospital from March, 1995 to December, 1995. The mean value for body weight was increased in the ginseng group than in the control group. There were no significant differences of serum hematocrit, hemoglobin, total protein and albumin in both groups. The total lymphocyte count was much more increased in the ginseng group than in the control group. The number of T cell, B cell, CD8, CD4, NK cell and activated T cell were increased in ginseng group more than in control group. The T cell was significantly increased on postoperative 5th day, 3 month and 6 month, and B cell on postoperative 6 month in ginseng group than in control group. The CD8 was significantly increased on postoperative 3 month and 6 month, CD4 on postoperative 5th day, and NK cell and activated T cell also on postoperative 6 month in ginseng group than in control group. In conclusion, red ginseng may be useful as a longterm adjuvant therapeutic agent for improving the immune function and anticarcinogenic effect after curative operation for immune compromizing gastrointestinal carcinoma patients.

BACKGROUNDS/AIMS: The prognosis of hepatic resection for hepatocellular carcinoma (HCC) in patients with cirrhosis is worse than in those without cirrhosis. In Korea, the hepatitis B virus prevalence rate is higher than in other countries. Therefore, we investigated patients' clinicopathologic and metabolic factors that affect the postoperative outcomes of hepatic resection for HCC in our hospital in Korea. METHODS: From August 2000 to December 2012, 171 HCC patients underwent hepatic resections at our institution. Two operative mortality cases and two short-term follow up cases were excluded. Data was collected from a retrospective chart review. There were 133 males (79.6%) and 34 females (20.3%), with a mean age of 58.2+/-10.2 years (range, 22-81 years), and the relationship between clinicopathologic and metabolic factors and the prognosis of patients with HCC undergoing hepatic resection were evaluated by univariate and multivariate analysis. RESULTS: Hypertension, major surgery, perioperative transfusion, resection with radiofrequency ablation (RFA) or cryoablation, and resection margin were risk factors for overall survival, and hypertension, albumin, resection with RFA or cryoablation, perioperative transfusion, and tumor size were risk factors for disease-free survival. CONCLUSIONS: We found that hypertension, perioperative transfusion, and resection with RFA or cryoablation were risk factors for both disease-free and overall survival after hepatic resection in HCC patients. Further study is required to clarify the influence of metabolic and other clinicopathologic factors on the prognosis of HCC.

Anatomic variations of the portal vein (PV) and bile duct (BD) are more common on the right lobe as compared with left lobe grafts in living donor liver transplantation (LDLT). We recently experienced a case of LDLT for hepatocellular carcinoma combined with liver cirrhosis secondary to hepatitis B virus and hepatitis C virus infection. The only available donor had right lobe graft with type IV PV associated with type IV BD. The patient underwent relaparotomy for PV stenting due to PV stenosis. Percutaneous transhepatic biliary drainage was done for a stricture at the site of biliary reconstruction. Thereafter, the patient was discharged in good health. Our experience suggests that, the use of right lobe graft with type IV PV accompanied by type IV BD should be the last choice for LDLT, because of its technical difficulty and risks of associated complications.

OBJECTIVES: The aim of this study was to evaluate the relationship between shift work and work-related injuries in a representative sample of Korean workers. METHODS: We used data from the Korean Working Condition Survey of 2006. The participants were 7,075 Korean workers 15 to 64 years of age. Logistic regression was employed to estimate the relationship between shift work and work-related injury using the SAS version 9.2 program. RESULTS: Shift work was significantly related to work-related injuries compared to non-shift workers(OR 2.40, 95% CI=1.65~3.48). When personal and occupational risk factors were accounted for, shift work had a statistically meaningful relationship with work-related injuries compared to non-shift work(OR 1.79, 95% CI=1.20~2.66). CONCLUSIONS: In this study, shift workers appear to have a higher risk of work-related injuries compared to non-shift workers. Work-related injuries in shift workers could be attributed to circadian rhythm disorder and sleep problems. Suitable arrangements that ensure flexible working times are needed for shift workers. Further study will be needed to identify and mitigate work-related injuries among shift workers.

PURPOSE: The mortality and morbidity rate after pancreaticoduodenectomy (PD) is still high, although the operative techniques and skills and the perioperative care has been improved. The incidence of PD for benign disease is 5~20%. The aim of this study is to determine the factors that differentiate between the benign group and the malignant group by comparing the clinical manifestations, and we studied the safety of performing PD for benign diseases by observing the early and late postoperative complications. METHODS: We retrospectively studied 124 patients who had been diagnosed with benign or malignant pancreatic diseases and who underwent PD between April 1995 and December 2005. We divided the patients into two groups, i.e., the benign group (20) and the malignant group (104), to compare their clinical characteristics and postoperative outcomes. Result: Chronic pancreatitis was the most common disease (35%) in the benign group and distal CBD cancer was the most common disease (40.4%) in the malignant group. Jaundice, weight loss, and elevation of CA 19-9 were more frequent in the malignant group than in the benign group (p<0.05). There were no statistical differences in the mortality rate (10.0% vs 6.7%), reoperation rate (5.0% vs 4.8%), hospital stays (27.1 days vs 24.0 days), early complications (30.0% vs 44.6%) and late complications (22.2% vs 26.4%) between the two groups. There were no mortality and newly developed malignancy during 33.4 months of follow-up period in benign group. CONCLUSION: On the preoperative evaluation, jaundice, weight loss, and elevation of CA 19-9 were more frequent in the malignant group. The postoperative early and late complications showed no difference between the two groups and complication rate was generally favorable. Thus, PD can be performed safely for benign diseases that cannot be treated in a conservative fashion and also for other clinically suspicious malignant diseases.

PURPOSE: A heterotopic pancreas is defined as one for which pancreatic tissue is present outside its usual or habitual location and without an anatomic relation either of continuity or of vascularization with the pancreas proper. Most heterotopic pancreases are incidentally encountered during surgery, and on rare occasions, epigastric pain, weight loss, hemorrhage, gastric outlet obstruction, and intussusception have been directly attributable to the presence of a heterotopic pancreas. The purpose of this article is to report the clinical characteristics of the heterotopic pancreas. METHOD: We retrospectively observed 24 patients, who had been pathologically proven to have a heterotopic pancreas, at the Department of Surgery, Korea University Hospital, from Jan. 1990 to Dec. 1998. RESULTS: 16 of the 24 cases were found incidentally during operations due to by other primary diseases; 8 cases were symptomatic. The ratio of males to females was 1.18:1 and most common sites were the stomach and the duodenum (71%). The mean size of the lesion was 1.26 cm, and the sizes in symptomatic cases were larger (mean 1.89 cm) than those in cases where the lesions were found incidentally (mean 0.94 cm). We experienced a case of a ductal adenocarcinoma originating from the heterotopic pancreas in the jejunum of a 73 year old man. CONCLUSION: A heterotopic pancreas should be considered in the differential diagnosis of submucosal tumors, polyps, ulceration, and intestinal tumors, When suspected, an intraoperative frozen section is recommended, and the range and the method of the operation should be decided based on the results of the frozen section.
