Abstract
Abstract
Background
Left atrial functional indices measured by two dimensional echocardiography (2DE) have prognostic significance for major cardiovascular events (MACE). Retrospective analysis using propensity score matching to assess the prognostic values of left atrial reservoir function measured by three dimensional speckle tracking analysis (3DSTA) was performed.
Methods
Two hundred sixty-four patients (Male 60%, 65±15yo) who underwent both clinically indicated 2DE and 3DSTA for various underlying heart diseases from January 4, 2013 to February 28, 2016 were followed to record MACE. Patients with significant mitral valve disease, history of pulmonary vein isolation and persistent atrial fibrillation were excluded. Maximum and minimum left atrial volume (LAVImax and LAVImin), left atrial emptying fraction (LAEmpF), peak global LA area ratio (LAAC), circumferential strain (LACS) and longitudinal strain (LALS) were measured using 3DSTA. Standard indices including peak global LVLS (2DLVLS) and left ventricular ejection fraction (LVEF) and LA volume index were also assessed by 2DE. Cutoff line for LA reservoir functional indices and 2DLVLS was determined using ROC analysis. Average treatment effect for the treated (ATT), Average treatment effect (ATE) for each index were calculated after propensity score matching for clinical indices (age, sex, coronary artery disease, hypertension, diabetes, eGFR <45 ml/min/1.73m2, LVEF <40%)
Results
During a mean follow-up of 547±435 days, MACE developed in 30 patients (7 cardiac death 6 stroke, 1 nonfatal MI, 22 admission for heart failure). Age, coronary artery disease (CAD), diabetes mellitus (DM), chronic kidney disease (CKD: eGFR< 45ml/min/1.73m2), LVEF, 2DLVLS, LAVImax and LAVImin by 2DE and all LA indices by 3DSTA had significant prognostic value by univariate analysis. LAEmpF and LALS by 3DSTA had higher ATT, ATE and Log rank χ2 than other LA indices and 2DLVLS. The model added LALS or LAEmpF by 3DSTA had higher prognostic value (LALS <10.6%: AUC; 0.82, HR; 5.57 CI: 2.32–14.06, LAEmpF <33.0%: AUC; 0.82, HR; 6.59 CI; 2.60–20.18) than LA volume indices by 2DE and also tended to be better than 2DLVLS (LVLS <6.04%: AUC; 0.77, HR; 5.37 CI; 2.06–13.73).
propensity score matching
Conclusion
LALS and LAEmpF by 3DSTA showed additive prognostic value for MACE.

Abstract
BACKGROUND/AIMS To investigate imaging characteristics and surgical results of adenomatous hyperplasia and early-stage hepatocellular carcinoma. METHODOLOGY A retrospective study set in the First Department of Surgery, University of Tokushima, Japan. From 1994 to 1997, 33 patients with 55 small hepatocellular carcinomas (< or = 3 cm) and 10 borderline lesions (3 adenomatous hyperplasia, 5 atypical adenomatous hyperplasia, 2 atypical adenomatous hyperplasia with focal malignancy) were enrolled for this study. The detectability of these lesions on imaging was evaluated. Cumulative survival and disease-free survival rates were also calculated. RESULTS Twenty-eight patients were incidentally diagnosed on ultrasonography during follow-up study for chronic disease. In the conventional studies, detection rates of ultrasonography, computed tomography and angiography for small hepatocellular carcinomas and borderline lesions were 76% 80%, 33% 10% and 36% 20%, respectively. Magnetic resonance imaging, intraoperative ultrasonography, helical computed tomography and portal angiographic computed tomography showed better results of 67% 20%, 100% 90%, 70% 50% and 74% 56%, respectively. On differential diagnosis, the ratio of echo level in small hepatocellular carcinomas was significantly higher than that in borderline lesions. The 3-year and 5-year survival rates for all patients were 61% and 41%, while disease-free survival rates at the corresponding times were 15% and 7%, respectively. A total of 25 patients (76%) developed intrahepatic recurrence during a mean follow-up of 33.8 months, although there was no recurrent lesion in 4 adenomatous hyperplasia patients treated with microwave coagulation therapy and ethanol injection intraoperatively. CONCLUSIONS For tumors larger than 1 cm in diameter, the detection rates with various diagnostic modalities were rather high. However, the differential diagnosis of borderline lesions from small hepatocellular carcinomas could be based on pathologic studies only. Early detection of small hepatic lesions and treatment by methods such as resection or ethanol injection are of critical importance in improving long-term survival.

Abstract
BACKGROUND/AIMS Hepatic resection is still associated with a higher morbidity than other major abdominal surgery. The aim of this study was to define risk factors for postoperative morbidity, and to evaluate the plasma cytokine pattern to detect early postoperative infection in patients with hepatocellular carcinoma. METHODOLOGY One hundred and thirty-nine hepatic resections for hepatocellular carcinoma over a 10-year period from 1987 to 1997 were performed. Preoperative and intraoperative predictors of morbid outcomes were analyzed using multiple regression in a stepwise, logistic model. The postoperative concentrations of interleukin-6, interleukin-8, granulocytecolony stimulating factor, endotoxin and hepatocyte growth factor were measured in 32 patients following hepatic resection. RESULTS Mortality rate within 30 postoperative days was 2.2%, with morbidity occurring in 40.2%. Significant pre- and intraoperative predictors for morbidity were ICGR15 and the presence of liver cirrhosis. Changes of interleukin-6, interleukin-8, granulocytecolony stimulating factor and endotoxin levels were not consistent with the occurrence of postoperative complications. However, the postoperative peak hepatocyte growth factor levels were positively correlated with morbidity. CONCLUSIONS ICGR15 and presence of liver cirrhosis had a marked effect on the incidence of postoperative complications after hepatectomy for hepatocellular carcinoma. An increase of serum hepatocyte growth factor level could be used to detect complications in the early postoperative period, but the inflammatory cytokine response after hepatectomy did not relate to an increased complication rate.

Abstract
Genomic imprinting is the phenomenon by which the two alleles of certain genes are differentially expressed according to their parental origin. Extensive analysis of allelic expression at multiple imprinted loci in a normal population has not performed so far. In the present study, we examined the allelic expression pattern of three imprinted genes in a panel of 262 Japanese normal individuals. We observed differences in the extent of maintenance of allele-specific expression of the three genes. The allelic expression of small nuclear ribonucleoprotein N (SNRPN) was stringently regulated while that of multimembrane-spanning polyspecific transporter-like gene 1 (IMPT1) showed a large degree of variation. Significant biallelic expression of insulin-like growth factor II (IGF2) was observed in about 10% of normal individuals. Our findings add to the accumulating evidence for variable allelic expression at multiple loci in a normal human population. This epigenetic heterogeneity can be a stable trait and potentially influence individual phenotypes.

Abstract
We report a rare case of hepatocellular carcinoma (HCC) for which intravenous administration of cisplatin (CDDP) was effective. A 48-year-old woman with recurrent HCC was admitted to our hospital. She had undergone right hepatectomy 1 year previously. A large tumor in the liver and multiple lung metastases were found by computed tomography in June 1995. She was icteric, and titers of serum alpha-fetoprotein (AFP; 214 ng/ml) and protein induced vitamin K absence or antagonist-II (PIVKA-II; 80 AU/ml) were high. According to these findings, she was diagnosed as having nonresectable recurrent HCC with extrahepatic lesions. She was treated by intravenous administration of CDDP. The dose of CDDP was 50 mg and it was infused once a week. One kur of CDDP was 4 weeks, and a total of four kur were administered. We noted that the lung metastases and primary liver tumor resolved after 1 kur of chemotherapy. The levels of serum AFP and PIVKA-II decreased markedly, to 26 ng/ml and <0.07 AU/ml, respectively. A complete response was obtained, and she maintained a good state of health for the next 6 months, until brain metastases occurred. She died 13 months after the initiation of treatment with CDDP. In general, intravenous CDDP cannot be recommended as a single agent for HCC therapy, but CDDP showed good antineoplastic activity in our patient.

Abstract
The influence on postoperative liver function of intermittent normothermic hepatic ischemia in cirrhotic patients was studied retrospectively. The mean total ischemia time was 88 (range 30-140) minutes in the hemi-hepatic occlusion group, and 68 (range 10-187) minutes in the total occlusion group. There were no operative deaths due to hepatic failure. Postoperative liver function improved within 1 week of the operation. There was no significant difference in the incidence of postoperative complications between the groups. Thus normothermic hepatic ischemia is tolerated for up to 180 minutes in the cirrhotic liver when an intermittent technique (15 minutes clamped and 5 minutes unclamped) is used.

Abstract
It is difficult to determine the prognosis of patients with hepatocellular carcinoma (HCC). Assessment of the clinicopathological and biological malignancy of HCC may help in determining treatment strategies and predicting outcome. The tumor DNA content, p53 protein expression, proliferating cell nuclear antigen labeling index, and argyrophilic proteins of nuclear organizer regions were used as markers of biological malignancy. A correlation between these biological parameters and clinicopathological factors was sought. DNA aneuploidy was observed in 31 of 80 tumors (38.8%). Aneuploidy increased as differentiation decreased. The overall survival rate of patients with aneuploid tumors was significantly poorer than that of patients with diploid tumors. p53 overexpression was observed in 18 of 80 tumors (22.5%). The incidence of p53 positivity increased significantly with increasing tumor size and poorer differentiation. The overall survival rate of p53-positive patients was significantly worse than that of p53-negative patients. The proliferating cell nuclear antigen labeling index and the mean number of argyrophilic proteins of nuclear organizer regions were higher in more poorly differentiated lesions. We conclude that DNA ploidy and p53 expression are useful prognostic indicators in HCC. Cell proliferation increases as HCC progresses. With progression, tumors tend to become more poorly differentiated.

Abstract
Gilbert's syndrome is the common cause of non hemolytic unconjugated hyperbilirubinemia with a prevalance of 3-7%. Gilbert's syndrome may introduce a selection of potential liver donors from brain death patients. We present a case of living-related liver transplantation (LRLT) from a donor with Gilbert's syndrome. A 22-year-old woman had been diagnosed as having liver cirrhosis at the age of 5. She underwent liver transplantation with the donor's left lobe as the graft. The donor, who was the father of the patient, had been diagnosed with Gilbert's syndrome. Although the recipient was well until 11 months after surgery, she died of subacute fulminant hepatitis 16 months after surgery. However, it was clear that the liver with Gilbert's syndrome could be used as a graft of living-related liver transplantation for adult recipients.

Abstract
BACKGROUND/AIMS The purpose of this study was to delineate the alterations in gastric physiology after pylorus-preserving duodenectomy (PPD). METHODOLOGY The duodenum was transected 2 cm distal to the pyloric ring in five dogs. A patch graft around the papilla of Vater was preserved. Reconstruction was completed using an end-to-end duodenojejunostomy, anastomosis of the patch graft to the jejunum, and cholecystojejunostomy, in that order. Gastric acid analysis, serum gastrin and secretin concentrations, and gastric emptying were investigated before and one and three months after surgery. RESULTS The postoperative mean basal and maximal acid outputs were not significantly increased. Fasting serum gastrin concentrations remained unchanged. The fasting serum secretin concentrations one month after surgery increased significantly as compared to the controls. There were no significant differences in meal-stimulated gastrin or secretin responses or gastric emptying after surgery. CONCLUSIONS The acid output and gut hormone release after PPD were maintained at preoperative levels. Preservation of the duodenal bulb is postulated to be responsible for the maintenance of near-normal gastric physiology.

Abstract
Here, we describe the clinical course of an adult patient who had living-related liver transplantation (LRLT) from a donor with Gilbert's syndrome and problems of living-related liver transplantation to adult patients. A 22-year-old woman had been diagnosed as having liver cirrhosis at the age of 5. She had undergone devascularization and transsection of the esophagus, and splenectomy for esophageal varices at the age of 8. Complications such as spontaneous bacterial peritonitis and nonspecific colitis sometimes appeared from 17 years old, and icterus and ascites had appeared on all such occasions. Such complications had frequently occurred from 21 years old. Total bilirubin was 5.5 mg/dl and direct bil. was 4.2 mg/dl. The patient and her family members were informed that LRLT might be possible, and they indicated that the patient's 57-year old father was willing to act as the donor. His liver function was examined. His hepatic function was normal except for hyperbilirubinemia (T. Bil. 2.3 mg/dl, D. Bil. 0.3 mg/dl). He was diagnosed with Gilbert's Syndrome because of an increase of unconjugated bilirubin levels during low caloric intake and nicotinic acid test. The standard liver volume for the patient was calculated to be 900 ml on the basis of body weight. Volumetric analysis with computed tomography revealed that the left lobe volume of the donor's liver was 512 ml, corresponding to 56% of the recipient standard liver volume. This proposal was submitted to the ethical committee of Tokushima University School of Medicine and was accepted. In March 28, 1995, the patient underwent LRLT with the donor's left lobe as the graft. The graft weight was 440 g and the graft corresponded to 49% of the recipient's standard liver volume. Volumetric analysis showed rapid enlargement of graft to 683 ml as early as one week after the operation. The donor has returned to work after discharge from the hospital. The recipient is well 11 months after surgery. Total bilirubin was 1.8 mg/dl and D. Bil 0.5 mg/dl. LRLT may become an option for adult recipients, if graft of more than 30% of the recipient standard liver volume is transplanted even from a donor with Gilbert's syndrome.

Abstract
We report herein the case of a 76-year-old man with intractable dumping syndrome which had manifested itself 3 years after he underwent a gastric resection and Billroth I reconstruction for a gastric ulcer. Despite aggressive medical therapy by the time of admission, he had suffered from disabling dumping symptoms for 9 years. In an attempt to relieve these symptoms, a 15-cm segment of the jejunum was placed isoperistaltically between the lesser curvature of the remnant stomach and the duodenum, and a selective vagotomy was performed. The dumping symptoms that he had experienced preoperatively completely disappeared after the revisory surgery. Postoperatively, an upper gastrointestinal series demonstrated a larger gastric pouch and slower gastric passage into the small intestine than what was seen preoperatively, while gastric emptying studies using the acetaminophen method also showed normal patterns in both the early and late postoperative phases. Thus, we consider that this surgical procedure is a simple and effective way to inhibit rapid gastric emptying and to slow intestinal transit in the treatment of dumping syndrome.

Abstract
Two cases with an anomalous arrangement of the pancreaticobiliary ducts (APBD) are reported in order to investigate the mechanism of carcinogenesis of the extrahepatic biliary tract from the aspect of DNA ploidy analysis. Highly elevated biliary enzymes were found in both cases. Although inflammatory changes without any metaplasia or neoplasia were observed histologically, a cytofluorometric nuclear DNA ploidy analysis showed an aneuploid low ploidy pattern in a histogram of the gall bladder, an aneuploid high ploidy pattern in a histogram of the common bile duct in one patient, and a diploidy pattern in the gall bladder, an aneuploid low pattern in the common bile duct in another case. These results may show that APBD may play a role in the development in DNA ploidy abnormality with refluxed pancreatic juice which may induce repeated irritation and inflammation. Radical surgery including a complete excision of the extrahepatic biliary tract followed by reconstruction may achieve better results with regard to undesirable consequences with an abnormal nuclear DNA ploidy pattern and decrease the likelihood of developing carcinoma.
