Abstract
A 75-year-old man was referred to our department because of an enlarging intrahepatic mass detected on magnetic resonance imaging (MRI) follow-up for another disease. MRI showed hypointensity on T1-weighted imaging and hyperintensity on T2-weighted imaging in liver segment 4. Abdominal plain computed tomography (CT) indicated a low-density lesion with an unclear boundary, measuring approximately 4 cm × 3 cm in liver segment 4. Dynamic CT showed early rim enhancement and gradual central enhancement. Contrast-enhanced CT also showed occlusion of the portal vein in segment 4. As the possibility of intrahepatic cholangiocarcinoma could not be excluded on imaging studies, we performed laparoscopic left medial sectionectomy. Histologically, the lesion showed diminished numbers of hepatocytes with increased collagen fibers compared with normal, with no patent portal vein. We considered this lesion a reactive lesion caused by collapse of the liver parenchyma owing to localized obstruction and loss of the portal vein. This lesion was pathologically diagnosed as portal biliopathy. We experienced an extremely rare case of intrahepatic mass-forming portal biliopathy that mimicked a hepatic tumor, which was diagnosed by laparoscopic resection. Portal biliopathy rarely forms intrahepatic mass lesions and must be distinguished from a malignant hepatic tumor.

Abstract
Anisakiasis is a parasitic infection caused by the ingestion of raw or undercooked seafood infected with Anisakis larvae. It generally affects the gastrointestinal tract, particularly the stomach, but very rare cases have been reported in which infection of the liver leads to the formation of inflammatory pseudotumors. We herein report an extremely rare case of an inflammatory pseudotumor induced by hepatic anisakiasis that was laparoscopically resected for the purpose of both diagnosis and treatment. A 51-year-old woman underwent a routine medical checkup by ultrasound examination, which incidentally detected a 15-mm mass on the surface of S6 of the liver. Because a malignant tumor could not be ruled out on several preoperative imaging studies, laparoscopic partial resection of the liver was performed. Histopathological examination revealed Anisakis larva in the inflammatory pseudotumor, suggesting hepatic anisakiasis. This report describes an extremely rare case of an inflammatory pseudotumor induced by hepatic anisakiasis. Because the preoperative diagnosis could not be obtained by several imaging modalities, laparoscopic liver resection with a sufficient margin might be suitable for diagnosis and treatment of this disease.

Abstract
Numerous potentially curative treatments have become available for patients with hepatocellular carcinoma (HCC) on the basis of the individual patient and tumor characteristics. Carbon-ion radiotherapy (C-ion RT) is a novel treatment option to reduce the physical burden in patients with HCC. However, the long-term outcomes and the clinical and pathological features of locoregional recurrence after initial C-ion RT are unclear. The present study reports the case of a patient who underwent a curative laparoscopic liver resection for the local recurrence of HCC after C-ion RT. A 73-year-old man was diagnosed with chronic hepatitis C and achieved a sustained virological response. During subsequent surveillance, a solitary HCC of 2.3 cm in diameter appeared in liver segment 7 (S7). While surgical resection was considered the best option, the patient chose C-ion RT as the initial HCC treatment. Although C-ion RT appeared to be successful for the primary lesion, enhanced computed tomography revealed that a hypervascular tumor had reappeared in the same area 16 months later. As HCC recurrence was suspected, several different examinations were performed. Computed tomography and magnetic resonance imaging showed that the recurrent tumor had irregular margins, and communication was suspected with the intrahepatic portal vein. A laparoscopic partial liver resection of S7 was planned. Histopathological examination of the excised specimen revealed proliferation of viable moderately to poorly differentiated HCC, with marked invasive growth and numerous portal vein infiltrations. To the best of our knowledge, this is the first report of surgery for locally recurrent HCC after C-ion RT. Oncological outcomes following C-ion RT for HCC remain unclear. Notably, there are cases of unusual recurrence with massive vascular invasion after C-ion RT. In the present case, the histological features were confirmed after C-ion RT for HCC. This case may raise concerns about the true efficacy of C-ion RT and warns against the easy choice of C-ion RT in spite of a resectable HCC.

Abstract
BACKGROUND Robotic pancreatectomy has been performed worldwide mainly using the da Vinci® Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA, USA). Recently, because of the death of some patents related to the da Vinci® system, new surgical robot systems have been introduced that are characterized by unique technical refinements. In Japan, the hinotori™ Surgical Robot System (Medicaroid Corporation, Kobe, Japan) was approved for use in gastroenterological surgery in October 2022. Since then, we have attempted complicated procedures using this robot. In this report, we report our first experience performing spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein using this first Japanese domestic surgical robot. CASE PRESENTATION The patient was a 58-year-old woman with a mass in the pancreatic tail identified during medical screening. Further examinations resulted in a diagnosis of a pancreatic neuroendocrine tumor. The patient consented to surgical resection, and we planned robotic spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein, using the hinotori™. Five trocars, including one port for the assistant surgeon, were placed in the upper abdomen. The operating unit was rolled in from the patient's right side. The pivot position was set for each robotic arm, and this setting was specific to the hinotori™. The cockpit surgeon performed all surgical procedures, excluding port placement and pancreatic transection. There were no unrecoverable device errors during the operation. The operation time was 531 min, and blood loss was 192 ml. The postoperative course was uneventful. We were able to safely perform this highly complicated surgery for a pancreatic tumor using the first Japanese domestic surgical robot platform. CONCLUSIONS The first Japanese domestic surgical robot platform, hinotori™, has different features from those of the da Vinci® and performed sufficiently as a surgical robot system in highly advanced pancreatic surgery.

Abstract
BACKGROUND Since indocyanine green (ICG) accumulates selectively in hepatocellular carcinoma (HCC) cells, it can be used to detect metastatic lesions. Lymph node metastasis of HCC is rarely observed, both simultaneously and metachronously. Therefore, it is sometimes difficult to identify metachronous lymph nodes during salvage surgery because of prior surgery. Herein, we report a case in which lymph node metastasis of HCC was successfully resected using an ICG navigation system. CASE PRESENTATION The patient was a 62-year-old man who had undergone radical liver resection for HCC 8 years ago. During surveillance, contrast-enhanced computed tomography (CT) revealed a mass in the hepatic hilum. Various diagnostic modalities suggested that the patient had a solitary metastatic lymph node of HCC, and extirpation of the tumor was planned. Intraoperative ICG fluorescence imaging allowed surgeons to clearly identify the target lesion. Histopathologically, the tumor was confirmed to be a lymph node metastasis of HCC. The patient's postoperative course was uneventful, and he remains alive without recurrence 2 years after the second surgery. CONCLUSION Intraoperative navigation surgery by ICG fluorescence imaging was useful for the safe resection of extrahepatic metastasis of HCC in a complicated situation.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICIs) are indicated for various cancers and are the mainstay of cancer immunotherapy. They are often associated with ICI-related pneumonitis (CIP), however, hindering a favorable clinical course. Recently, non-oncology concomitant drugs have been reported to affect the efficacy and toxicity of ICIs; however, the association between these drugs and the risk for CIP is uncertain. The aim of this study was to assess the impact of baseline concomitant drugs on CIP incidence in ICI-treated advanced cancer patients. PATIENTS AND METHODS This was a single-center retrospective study that included a cohort of 511 patients with advanced cancer (melanoma and non-small-cell lung, head and neck, genitourinary, and other types of cancer) treated with ICIs. Univariable analysis was conducted to identify baseline co-medications associated with CIP incidence. A propensity score matching analysis was used to adjust for potential CIP risk factors, and multivariable analysis was carried out to assess the impact of the identified co-medications on CIP risk. RESULTS Forty-seven (9.2%) patients developed CIP. In these patients, the organizing pneumonia pattern was the dominant radiological phenotype, and 42.6% had grade ≥3 CIP, including one patient with grade 5. Of the investigated baseline co-medications, the proportion of antiplatelet drugs (n = 50, 9.8%) was higher in patients with CIP (23.4% versus 8.4%). After propensity score matching, the CIP incidence was higher in patients with baseline antiplatelet drugs (22% versus 6%). Finally, baseline antiplatelet drug use was demonstrated to increase the risk for CIP incidence regardless of cancer type (hazard ratio, 3.46; 95% confidence interval 1.21-9.86). CONCLUSIONS An association between concomitant antiplatelet drug use at baseline and an increased risk for CIP was seen in our database. This implies the importance of assessing concomitant medications for CIP risk management.

Abstract
BACKGROUND Although robotic surgery has rapidly spread in pancreatectomy [1], the procedure is performed by the da Vinci™ Surgical System (Intuitive Surgical Inc., CA), the most common surgical robot in the world [2]. We herein present our first experience of robotic distal pancreatectomy using a new Japanese surgical robot named the hinotori™ Surgical Robot System (Medicaroid Corporation, Kobe, Japan). METHODS A 68-year-old man who was found to have the mass lesion in the pancreatic tail in a medical examination. Investigations, including various imaging studies suggested a diagnosis of pancreatic cancer (Fig. 1). The patient was considered for robotic pancreatectomy. RESULTS Five trocars, including one port for the assistant surgeon, were placed at the upper abdomen. The operation unit was rolled in from the right side (Fig. 2). The patient successfully underwent robotic distal pancreatectomy combined with dissection of the regional lymph nodes using the hinotori™ system. The cockpit surgeon performed all procedures, excluding port placement, vessel clipping, and transection of the pancreas. There were no unrecoverable device errors in this operation. The total operation time was 473 minutes, and the estimated blood loss was 182 ml. The postoperative course was uneventful, and hospital length of stay was 10 days. Pathological diagnosis was pancreatic cancer, T1N1M0, Stage ⅡB. Adjuvant chemotherapy using S-1 was administered, and he has survived without recurrence for 3 months after the curative resection. CONCLUSIONS This is the first report of robotic pancreatectomy using the hinotori™ system, which showed the favorable perioperative results. The accumulation of experience and further studies are required to confirm its clinical benefits.

Abstract
AIM Laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) located in the posterosuperior segments (PS) have generally been considered more difficult than those for HCC in anterolateral segments (AL), but may be safe and feasible for selected patients with accumulated experience. In the present study, we investigated the effectiveness of LLR for single nodular HCCs ≤3 cm located in PS. METHODS In total, 473 patients who underwent partial liver resection for single nodular HCCs ≤3 cm at the 18 institutions belonging to the Kyusyu Study Group of Liver Surgery from January 2010 to December 2018 were enrolled. The short-term outcomes of laparoscopic partial liver resection and open liver resection (OLR) for HCCs ≤3 cm, with subgroup analysis of PS and AL, were compared using propensity score-matching analysis. Furthermore, results were also compared between LLR-PS and LLR-AL. RESULTS The original cohort of patients with HCC ≤3 cm included 328 patients with LLR and 145 with OLR. After matching, 140 patients with LLR and 140 with OLR were analyzed. Significant differences were found between groups in terms of volume of blood loss (median, 55 vs. 287 ml, p < 0.001), postoperative complications (0.71 vs. 8.57%, p = 0.003), and postoperative hospital stay (median, 9 vs. 14 days, p < 0.001). The results of subgroup analysis of PS were similar. Short-term outcomes did not differ significantly between LLR-PS and LLR-AL after matching. CONCLUSIONS Laparoscopic partial resection could be the preferred option for single nodular HCCs ≤3 cm located in PS.

Abstract
BACKGROUND Multicystic biliary hamartoma (MCBH) is an extremely rare benign liver lesion characterized by a gross well-circumscribed multicystic honeycomb appearance. This report presents a MCBH case with a marked peribiliary gland component which showed unusual histology. CASE PRESENTATION A 63-year-old Japanese male was admitted to our hospital for a detailed examination of a hepatic cystic lesion, which was originally detected 14 years ago and had slowly enlarged. A preoperative imaging study revealed a well-demarcated multicystic lesion without communication to the biliary tracts. The possible clinical diagnoses were mucinous cystic neoplasm (MCN) or MCBH. The lesion was successfully resected by purely laparoscopic right anterior sectionectomy. The cut surfaces of resected specimens grossly exhibited a well-circumscribed multicystic lesion with a thick septum. Histologically, the cyst wall was covered by cuboidal epithelial cells resembling epithelium of the bile duct while abundant small ducts, which morphologically resembled peribiliary glands, were observed among the fibrous stroma of the thick septum. Although possible pathological diagnosis varied, including intrahepatic cholangiocarcinoma, intraductal papillary neoplasm of the bile duct, biliary adenofibroma, MCN and MCBH, the lesion was finally diagnosed as MCBH with a marked peribiliary gland component. CONCLUSIONS MCBH can contain abundant peribiliary glands in the fibrous stroma. A pathologist should be careful not to diagnose such peribiliary glands in MCBH as neoplastic glands.

Abstract
BACKGROUND In this study, we aimed to develop and validate a nomogram to predict overall survival (OS) and recurrence-free survival (RFS) in patients who underwent curative resection of ampulla of Vater (AOV) cancer. This is the first study for nomograms in AOV cancer patients using retrospective data based on an international multicenter study. METHODS A total of 2007 patients with AOV adenocarcinoma who received operative therapy between 2002 January and 2015 December in Korea and Japan were retrospectively assessed to develop a prediction model. Nomograms for 5-year OS and 3-year RFS were constructed by dividing the patients who received and who did not receive adjuvant therapy after surgery, respectively. Significant risk factors were identified by univariate and multivariate Cox analyses. Performance assessment of the four prediction models was conducted by the Harrell's concordance index (C-index) and calibration curves using bootstrapping. RESULTS A total of 2007 and 1873 patients were collected for nomogram construction to predict 5-year OS and 3-year RFS. We developed four types of nomograms, including models for 5-year OS and 3-year RFS in patients who did not receive postoperative adjuvant therapy, and 5-year OS and 3-year RFS in patients who received postoperative adjuvant therapy. The C-indices of these nomograms were 0.795 (95% confidence interval [CI]: 0.766-0.823), 0.712 (95% CI: 0.674-0.750), 0.804 (95% CI: 0.7778-0.829), and 0.703 (95% CI: 0.669-0.737), respectively. CONCLUSIONS This predictive model could help clinicians to choose optimal treatment and precisely predict prognosis in AOV cancer patients.

Abstract
Hemosuccus pancreaticus (HP) is a condition that is defined as gastrointestinal hemorrhage which occurs through the pancreatic duct. We present the rare case of a 75-year-old woman who developed HP caused by intraductal papillary mucinous neoplasm (IPMN). She had been followed for sarcoidosis, splenic artery aneurysm and pancreatic cyst. The patient presented to the emergency room of our hospital with epigastric pain and bloody discharge. Computed tomography revealed hemorrhage from a splenic artery aneurysm in a cystic lesion of the pancreas. On angiography, extravasation from the splenic artery was observed. Thus, we performed coil embolization. After interventional radiography (IVR), magnetic resonance imaging and endoscopic retrograde pancreatography showed a branch duct IPMN. Based on these findings, elective laparoscopic distal pancreatectomy was performed. The histopathological diagnosis was IPMN with HP caused by rupture of a splenic artery aneurysm. For such complicated cases, minimally invasive surgery is applicable after successful hemostasis by IVR.

Abstract
Abstract
Background
We previously showed that angiotensin-converting-enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARB) were associated with heart failure with recovered ejection fraction (HFrecEF) in patients with dilated cardiomyopathy (DCM). However, the different effects of these drugs on cardiac reverse remodeling have not been fully elucidated. The aim of this study was to assess comparative effectiveness of ACEi versus ARB on recovery of left ventricular ejection fraction (LVEF) among patients with DCM.
Methods
We analyzed the clinical personal records of DCM, a national database of Japanese Ministry of Health, Labour and Welfare, from 2003 to 2014. Patients with LVEF <40% and on either ACEi or ARB were included. Eligible patients were divided into two groups according to the use of ACEi or ARB. A one-to-one propensity case-matched analysis was used. A propensity score was estimated by fitting a logistic-regression model which adjusted for age, sex, duration of HF, NYHA functional class (I-II vs. III-IV), systolic blood pressure, diastolic blood pressure, heart rate, atrial fibrillation, pacing, left bundle branch block, LVEF, hypertension, diabetes mellitus, hyperuricemia, chronic kidney disease, B-type natriuretic peptide (BNP), beta-blockers, mineralocorticoid receptor antagonists, loop diuretics, thiazides, digitalis, amiodarone, and oral inotropes. The primary outcome was defined as LVEF ≥40% at 3 years of follow-up.
Results
Out of 4,618 eligible patients, 2,238 patients received ACEi and 2,380 patients received ARB. Propensity score matching yielded 1,341 pairs. Mean age was 56.0 years and 2,041 (76.1%) was male. Mean LVEF was 27.6%, and median duration of HF was 1 year. The primary outcome was observed more frequently in ARB group than in ACEi group (59.8% vs. 54.1%; odds ratio [OR] 1.26; 95% confidence interval [CI] 1.08–1.47; P=0.003). The change in LVEF from baseline to 3 years of follow-up was greater in ARB group than in ACEi group (15.8±0.4 vs. 14.0±0.4%, P=0.002). In the ACEi group, 946 patients (70.6%) continued to receive ACEi at 3 years of follow-up, while 1,088 patients (81.3%) continued to receive ARB in the ARB group. Per-protocol analysis consistently showed that ARB increased the prevalence of HFrecEF (62.0% vs. 54.0%; OR 1.39; 95% CI 1.17–1.66; P<0.001). Subgroup analysis showed that ARB increased frequency of HFrecEF regardless systolic blood pressure, heart rate, LVEF, chronic kidney disease, and concomitant use of beta-blockers and mineralocorticoid receptor antagonists.
Conclusions
The use of ARB was associated with HFrecEF more frequently than ACEi among patients with DCM and reduced LVEF.

Abstract
Abstract
Background and aim
Heart failure (HF) is a growing healthcare problem worldwide. This study aimed to describe clinical characteristics and long-term outcomes of HF patients in Japan.
Methods and results
JROADHF (the Japanese Registry Of Acute Decompensated Heart Failure) is a retrospective, multicentre, nationwide observational database of 13,238 patients hospitalized due to HF in 128 hospitals randomly selected from Japanese Circulation Society (JCS)-certified teaching hospitals during 2013. At inclusion, demographic and clinical data were collected from medical records with linkage to a nationwide claim-based database, the Japanese Diagnosis Procedure Combination (DPC). Patients were followed up to 5 years after discharge at each participating site. Patients were old as the median age of 81 years and women were older (74.8±12.8 vs 81.6±11.1 y.o). Mean left ventricular ejection fraction (LVEF) was 47%, and 45% were HF with preserved ejection fraction of >50% (HFpEF). Causes of HF included ischemic in 27%, valvular in 19%, arrhythmia in 17%, and hypertensive in 16%. Median length of hospital stay was 18 days and in-hospital mortality was 7.7%. All-cause mortality during 1 and 4 years were 22.3% and 48.4%, respectively. Hospitalization rates due to HF within 1 and 4 years were as high as 30.5 and 48.4%, respectively.
Conclusions
Contemporary nationwide registry revealed that hospitalized HF patients were elder and had more HFpEF, and their prognosis was still poor compared to the data shown in prior registries.

Abstract
Abstract
Background
Direct oral anticoagulants (DOACs) have been shown to be safe and effective in patients with atrial fibrillation (AF) as compared with warfarin, a vitamin K antagonist. However, the safety and efficacy of DOACs in patients with AF and heart failure (HF) have been unclear.
Purpose
The purpose of this study was to determine whether DOACs can improve long-term outcomes in patients with AF and HF as compared with warfarin.
Methods
We analyzed the JROADHF registry, which was a multicenter registry of patients hospitalized for the worsening HF in Japan. Baseline data were collected during the episode of index hospitalization from April 2013 to March 2014. Follow-up data were collected up to 4.5 years after the index hospitalization. Patients with AF and creatinine clearance ≥15 ml/min/1.73m2 were included. Valvular heart disease, congenital heart disease, and constrictive pericarditis were excluded. Eligible patients were divided into two groups according to the use of warfarin or DOACs. The primary outcome was defined as all-cause death. The secondary outcomes were defined as cardiovascular death, composite of all-cause death or cardiovascular hospitalization, and composite of stroke death or stroke related hospitalization. A one to one propensity case-matched analysis was used. Complete case analysis and multiple imputation analysis were also conducted as sensitivity analyses.
Results
Out of the 14,847 patients in this registry, 2,175 had AF, creatinine clearance ≥15 ml/min/1.73m2 and discharged alive. Propensity score matching yielded 475 pairs. In matching cohort, mean age was 76.5 years and 513 (54.0%) was male. Mean left ventricular ejection fraction was 48.6±16.4%. During a mean follow-up of 3.2 years, patients with DOACs had a lower incidence rate of all-cause death than those with warfarin (75.2 vs. 99.9 death per 1000 patient-years; rate ratio (RR) 0.75; 95% confidence interval [CI] 0.59–0.96; P=0.022). The incidence of cardiovascular death tended to be lower in DOAC group (30.9 vs. 43.1; incidence rate ratio 0.72; 95% CI 0.49–1.04; P=0.081). There were no significant differences in the incidence of composite of all cause death or cardiovascular hospitalization (252.3 vs. 269.4; RR 0.94; 95% CI 0.79–1.11; P=0.45) or composite of stroke death or stroke related hospitalization (13.1 vs. 16.7; RR 0.79; 95% CI 0.39–1.59; P=0.50). Cox regression model showed that DOAC was associated with lower mortality than warfarin (hazard ratio (HR) 0.75; 95% CI 0.59–0.96; P=0.023). Complete case analysis (HR 0.78; 95% CI 0.63–0.98; P=0.035) and multiple imputation analysis (HR 0.78; 95% CI 0.68–0.84; P<0.001) also showed the same results. A restricted cubic spline analysis demonstrated that the effectiveness of DOACs over warfarin waned with age, and DOACs were effective in patients younger than 80 years old.
Conclusion
Use of DOACs was associated with better long-term outcome in patients with HF as compared with warfarin.

Abstract
Abstract
Background
Individual risk stratification is fundamental in the care of heart failure (HF) patients. However, the prediction performance of risk scores, such as MAGGIC and SHFM, is not adequate and, more importantly, they need additional predictors including various biomarkers, imaging data, and environmental factors. Data from a case-mix payment system including diagnosis and procedures with outcomes can be used to develop the risk prediction models, allowing the use of big data for a more accurate prediction of mortality.
Purpose
This study aimed to develop artificial intelligence (AI) models for predicting 1-year mortality in patients hospitalized due to HF.
Methods
We analyzed the data from 10175 patients enrolled in the Japanese Registry Of Acute Decompensated Heart Failure (JROADHF). Candidate variables included the data obtained from a payment system introduced by the Japanese government, the Diagnosis Procedure Combination (DPC), which included each patient profile (age, sex, height, weight), principal diagnosis for hospitalization, comorbidities, procedures, length of hospital stay, and discharge status. They did not include clinical data available from patients such as vital status, laboratory data including bio-makers, electrocardiographic and echocardiographic data. The collected data were divided into the training set and the validation set (80%: 20%). With the training set, 5 AI models (logistic regression, random forest, support vector machine, neural network, and ensemble classifier) learned the one-year mortality results. AI models were evaluated by using the validation set with ROC analysis. The training and validation steps were repeated 10 times with different seed values to calculate the C-statistic of each model. We also identified the predictors for one-year prognosis acquired from the AI models.
Results
At 1-year of follow-up, a total of 1727 patients had died (17%). Among the machine learning models, the ensemble classifier showed the highest C-statistic of 0.76 (95% confidence interval: 0.75 to 0.77) for predicting mortality. Top predictors acquired from the random forest classifier was ADL (Barthel Index) at discharge, age, body mass index, and length of hospital stay.
Conclusion
By using AI-based analysis of a national case-mix payment system data, the present risk stratification model could predict the one-year mortality of hospitalized HF patients without any quantitative laboratory and physiological data. Furthermore, the present results could emphasize the advantage of this approach using the claim-based data that are routinely collected in a usual daily practice with no need to collect any additional information.

Withdrawal of optimal medical therapy has been reported to relapse cardiac dysfunction in patients with dilated cardiomyopathy (DCM) whose cardiac function had improved. However, it is unknown whether beta-blockers can prevent deterioration of cardiac function in those patients.
Purpose
We examined the effect of beta-blockers on left ventricular ejection fraction (LVEF) in recovered DCM.
Methods
We analyzed the clinical personal records of DCM, a national database of Japanese Ministry of Health, Labor and Welfare, between 2003 and 2014. Recovered DCM was defined as a previously documented LVEF <40% and a current LVEF ≥40%. Patients with recovered DCM were divided into two groups according to the use of beta-blockers. The primary outcome was defined as a decrease in LVEF >10% at two years of follow-up. A one to one propensity case-matched analysis was used. A per-protocol analysis was also performed. Considering intra- and inter-observer variability of echocardiographic evaluations, we also examined outcomes by multivariable logistic regression model after changing the inclusion criteria as follows; (1) previous LVEF <40% and current LVEF ≥40%; (2) previous LVEF <35% and current LVEF ≥40%; (3) previous LVEF <30% and current LVEF ≥40%; (4) previous LVEF <40% and current LVEF ≥50%. Outcomes were also changed as (1) decrease in LVEF ≥5% (2) decrease in LVEF ≥10% (3) decrease in LVEF ≥15%. The analysis of outcomes by using combination of multiple imputation and inverse probability of treatment weighting was also conducted to assess the effects of missing data and selection bias attributable to propensity score matching on outcomes.
Results
From 2003 to 2014, 40,794 consecutive patients with DCM were screened. Out of 5,338 eligible patients, 4,078 received beta-blockers. Propensity score matching yielded 998 pairs. Mean age was 61.7 years and 1,497 (75.0%) was male. Mean LVEF was 49.1±8.1%. The primary outcome was observed less frequently in beta-blocker group than in no beta-blocker group (18.0% vs. 23.5%; odds ratio [OR] 0.72; 95% confidence interval [CI] 0.58–0.89; P=0.003). The prevalence of increases in LVDd (11.5% vs. 15.8%; OR 0.70; 95% CI 0.54–0.91; P=0.007) and LVDs (23.1% vs. 27.2%; OR 0.80; 95% CI 0.65–0.99; P=0.041) was also lower in the beta-blocker group. Similar results were obtained in per-protocol analysis. These results were robust to several sensitivity analyses. As a result of preventing a decrease in LVEF, the deterioration to HFrEF was also prevented by the use of beta-blocker (23.6% vs. 30.6%). Subgroup analysis demonstrated that beta-blocker prevented decrease in LVEF regardless of atrial fibrillation.
Conclusion
Use of beta-blocker was associated with prevention of decrease in left ventricular ejection fraction in patients with recovered DCM.

Abstract
We examined CD1a-positive dendritic cell (CD1a-DC) infiltration in gallbladder cancer. The group with high CD1a-DC infiltration had fewer patients with distant metastasis. A high level of CD1a-DC infiltration was associated with longer overall survival. High CD1a-DC infiltration was also associated with longer disease-specific survival. S100-DC and tumor-infiltrating lymphocyte statuses were without effect on survival.
Gallbladder cancer (GBC) is an aggressive malignancy with a poor prognosis. Antigen-presenting dendritic cells (DCs) play a central role in antitumor immunity. DCs expressing CD1a (CD1a-DCs) are considered immature DCs. The aim of this study was to evaluate the clinical impact of CD1a-DC infiltration into GBC tissue. Seventy-five patients with GBC (excluding non-invasive and intramucosal cancer) were enrolled. Immunohistochemistry for CD1a, S100 and CD8 was performed using representative surgically resected specimens. The cases were divided into a high CD1a-DC group (27 cases, 36%) and low CD1a-DC group (48 cases, 64%) according to the degree of CD1a-DC infiltration/aggregation. The high CD1a-DC group contained fewer patients with distant metastasis (P = 0.039) and more patients given postoperative chemotherapy (P = 0.038). The high CD1a-DC group had significantly longer overall survival (P = 0.001) and disease-specific survival (P = 0.002) than the low CD1a-DC group. In contrast, S100-DC and CD8+ tumor-infiltrating lymphocyte statuses were without effect on OS or DSS. The results of multivariate analyses indicated that the degree of infiltration/aggregation of CD1a-DCs was an independent prognostic factor associated with a favorable prognosis after surgery.

Abstract
BACKGROUND Effective education about endoscopic surgery (ES) is greatly needed for unskilled surgeons, especially at low-volume institutions, to maintain the safety of patients. We have tried to establish the remote educational system using videoconference system through the internet for education about ES to surgeons belonging to affiliate institutions. The aim of this manuscript was to report the potential to establish a comfortable remote educational system and to debate its advantages. METHODS We established a local remote educational conference system by combining the use of a general web conferencing system and a synchronized remote video playback system with annotation function through a high-speed internet. RESULTS During 2014-2019, we conducted 14 videoconferences to review and improve surgeons' skills in performing ES at affiliated institutions. At these conferences, while an uncut video of ES that had been performed at one of the affiliated institutions was shown, the surgical procedure was discussed frankly, and expert surgeons advised improvements. The annotation system is useful for easy, prompt recognition among the audience regarding anatomical structures and procedures that are difficult to explain verbally. CONCLUSIONS This system is of low initial cost and offers easy participation and high-quality videos. It would therefore be a useful tool for regional ES education.

Abstract
AIM Combined hepatocellular cholangiocarcinoma (cHCC-CCA) is a very rare subtype of primary liver carcinoma; therefore, its clinicopathological characteristics have not yet been elucidated in detail. The aim of the study was to reveal the clinicopathological characteristics and prognostic factors of cHCC-CCA after hepatic resection (HR) METHODS: A total of 124 patients who underwent curative HR for cHCC-CCA between 2000 and 2016 were enrolled in this multi-institutional study conducted by the Kyushu Study Group of Liver Surgery. Clinicopathological analysis was performed from the viewpoint of patient prognosis. RESULTS A total of 62 patients (50%) had early recurrence within 1.5 years after HR, including 36 patients (58%) with extrahepatic recurrence. In contrast, just four patients (3%) had late recurrence occurring >3 years after HR. The independent predictors of early recurrence were as follows: des-gamma carboxyprothrombin >40 mAU/mL (odds ratio 26.2, P = 0.0117), carbohydrate antigen 19-9>37 IU/l (odds ratio 18.0, P = 0.0200), and poorly differentiated HCC or CCA (odds ratio 11.2, P = 0.0259). CONCLUSIONS Half of the patients with cHCC-CCA had early recurrence after HR. Preoperative elevation of des-gamma carboxyprothrombin or carbohydrate antigen 19-9 and the existence of poorly differentiated components of HCC or CCA in resected specimens are predictors of its early recurrence.

Abstract
Abstract
Background
Mitochondrial dysfunction has been highlighted as a critical driver of cardiac remodeling and failure. Mitochondria contains about 1500 proteins, 99% of which are encoded in the nuclear genome. Therefore, protein import into mitochondria is essential to maintain mitochondrial function. Previous reports suggest that nuclear-encoded mitochondrial precursor proteins import into mitochondria by multiple complex; translocase of outer membrane (TOM), translocase of inner membrane (TIM), and protein associated motor (PAM). However, the role of these protein import machineries of mitochondria in cardiac remodeling remains to be elucidated.
Objective
The purpose of this study was to elucidate the role of TOM, TIM, and PAM complex in cardiac remodeling and cardiomyocyte death.
Methods and results
C57BL/6J mice were subjected to myocardial infarction (MI) by permanent ligation of left anterior descending artery. Four weeks after operation, MI-mice demonstrated left ventricular (LV) dilation (LV end-diastolic dimension: 3.91 vs. 5.54 mm, n=8–11, p<0.05) and dysfunction (LV fractional shortening: 33.3 vs. 7.7%, n=8–11, p<0.05). Tim44 protein levels, a component of PAM complex, in mitochondrial fraction from non-infarcted left ventricle were significantly decreased compared with those in the heart from sham-operated mice by 39% (p<0.05), whereas other proteins related to TOM, TIM and PAM complex such as Tom20, Tom22, Tom40, Tom70, Tim22, Tim23 and mtHSP70 were not altered between MI-mice and sham-mice. In addition, blue-native polyacrylamide gel electrophoresis revealed that a protein complex associated to Tim44 was significantly decreased in non-infarcted LV by 40% (p<0.05). Superoxide dismutase 2 (SOD2), a mitochondrial matrix protein, was decreased in mitochondrial fraction from non-infarcted LV by 20% (p<0.05), accompanied by enhancing protein carbonylation, a marker of oxidative stress, by 40% (p<0.05). To assess the role of Tim44, it was downregulated by small interfering RNA in cultured neonatal rat ventricular myocytes (NRVMs). Knockdown of Tim44 significantly decreased SOD2 protein levels in mitochondrial fractionation (22%, p<0.05), with no significant changes in its mRNA levels. Furthermore, knockdown of Tim44 significantly increased protein carbonylation (20%, p<0.05) and cleaved caspase 3 (47%, p<0.05) and decreased cell viability (69%, p<0.05), assessed by cell titer assay, in H2O2-treatred NRVMs.
Conclusions
Downregulation of Tim44 exacerbates oxidative stress-induced ROS production and cardiomyocytes death, which is associated with a decrease in mitochondrial SOD2. Endogenous Tim44 might play a protective role in cardiac remodeling by attenuating oxidative stress and cardiomyocyte death via SOD2 import into mitochondria.

Abstract
Abstract
Background
Cardiac hypertrophy is an independent risk factor for heart failure and cardiac death. Hexosamine biosynthesis pathway (HBP), an accessory pathways of glycolysis, is known to be involved in the attachment of O-linked N-acetylglucosamine motif (O-GlcNAcylation) to proteins, a post-translational modification. However, the role of HBP has not been determined in pathological cardiac hypertrophy.
Purpose
The purpose of this study to examine whether glutamine-fructose-6-phosphate amidotransferase 2 (GFAT2), a critical enzyme of HBP, mediates cardiac hypertrophy by protein O-GlcNAcylation and activating hypertrophic signaling in cardiomyocytes.
Methods and results
C57BL/6J mice were treated with isoproterenol (ISO: 15 mg/kg/day, 1 week) with or without 6-Diazo-5-oxo-L-norleucine (DON, an inhibitor of GFAT: 500 μg/kg/day, 1week). ISO-treated mice (ISO+vehicle) showed cardiac hypertrophy, which were attenuated in ISO and DON-treated mice (ISO+DON) (heart weight to tibial length ratio: 7.70±0.09 vs. 7.11±0.15 mg/mm, n=12, p<0.05, left ventricular wall thickness: 1.05±0.02 vs. 0.86±0.03 mm, n=6, p<0.05). Cardiomyocyte cross-sectional area was also decreased in ISO+DON compared with ISO+vehicle (309±25 vs. 252±13 mm2, n=,3 p<0.05). Whereas expression levels of GFAT2 and protein O-GlcNAcylation in the heart were increased in ISO+vehicle compared with control+vehicle by 3.3 and 1.5 folds, respectively (n=9 and n=9, p<0.05), expression levels of O-GlcNAc transferase (OGT) and the β-N-acetylglucosaminidase (OGA), other enzymes regulating O-GlcNAcylation, were not altered in both groups, indicating that ISO activated HBP by GFAT2. Protein O-GlcNAcylation in ISO+DON was lower than that in ISO+vehicle by 83% (n=9, p<0.05). In addition, phosphorylation of Akt, a critical mediator of cardiac hypertrophy, but not other mediators of cardiac hypertrophy such as ERK, JNK, or p38MAPK, was significantly decreased in ISO+DON by 76% (n=9, p<0.05). In cultured neonatal rat ventricular myocytes, treatment with ISO (1μM, 12h) increased the expression levels of GFAT2 and protein O-GlcNAcylation by 1.3 and 1.5 folds, respectively (n=6 and n=6, p<0.05), but not GFAT1. Furthermore, ISO stimulation increased a direct O-GlcNAcylation of Akt by 1.4 folds (n=3, p<0.05). Downregulation of GFAT2 by RNA silencing decreased cell size by 82% (n=6, p<0.05) and protein O-GlcNAcylation and phosphorylation of Akt by 76% and 54%, respectively (n=9 and n=9, p<0.05) in cardiomyocyte treated with ISO. Conversely, administration of glucosamine, a substrate of HBP, increased protein of O-GlcNAcylation and phosphorylation of Akt by 1.3 and 1.8 folds, respectively (n=6 and n=6, p<0.05).
Conclusions
GFAT2, a limiting enzyme of HBP, mediates pathological cardiac hypertrophy by Akt activation probably due to its O-GlcNAcylation. GFAT2-O-GlcNAcylation-Akt pathway might be a potential novel therapeutic target for cardiac hypertrophy.

Abstract
Abstract
Background
Invariant natural killer T (iNKT) cells orchestrate tissue inflammation via regulating various cytokine productions, especially strongly upregulating interferon (IFN)-γ. Activation of iNKT cells have been previously reported to exert protective effects against post-infarcted cardiac remodeling and cardiac ischemia/reperfusion injury. However, the role of iNKT cells has not been determined in doxorubicin (DOX)-induced cardiomyopathy.
Purpose
The purpose of this study was to examine whether the activation of iNKT cells by α-galactosylceramide (αGC), which specifically activates iNKT cells, could affect DOX-induced cardiomyopathy, and if so, to elucidate its downstream target.
Methods
C57BL/6J mice were received the intraperitoneal injection of either αGC (0.1μg/g, n=11) or vehicle (n=13). After 1 week, these mice were treated with a low dose of DOX (18mg/kg via intravenous 3 injections over 1 week), and were followed during 14 days.
Results
DOX mice (DOX+vehicle) showed left ventricular (LV) dysfunction and dilatation, which were significantly ameliorated in DOX mice receiving αGC (DOX+αGC) (LV fractional shortening: 27.4±4.31 vs. 31.5±4.62%, p<0.05, LV end-diastolic diameter: 3.70±0.16 vs. 3.32±0.23mm, p<0.05), with no significant changes in arterial pressure, body weight, and food consumption, 14 days after DOX injection. DOX+vehicle demonstrated a significant decrease in myocardial gene expression of Vα14Jα18, a specific marker of iNKT cells, and IFN-γ compared with control mice. Vα14Jα18 expression levels were higher in DOX+αGC than DOX+vehicle by 9.2 folds (p<0.05). Consistent with this change, IFN-γ was higher in DOX+αGC than DOX+vehicle by 4.4 folds (p<0.05), whereas interleukin (IL)-1, IL-4, IL-6, IL-10, IL-17, IL-23, and tumor necrosis factor (TNF)-α were not altered in both groups. Phosphorylation of Akt, its active form, in the heart was significantly increased in DOX+αGC compared with DOX+vehicle by 1.8 folds (p<0.05).
Conclusions
Activation of iNKT cells by αGC play a protective role against DOX-induced cardiac dysfunction, which was associated with enhancing expression of IFN-γ and activating Akt. Therapies designed to activate iNKT cells might be beneficial to protect the heart from DOX injury.

Abstract
AIM Hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality worldwide. An excess of iron in liver tissue causes oxidative stress, leading to hepatocellular carcinogenesis. Iron metabolism, which is regulated by a complex mechanism, is important for cancer cell survival. The aim of this study is to clarify the role of iron regulatory protein in the progression of HCC and in patient outcome. METHODS AND RESULTS We first investigated the mRNA level of iron metabolism-related genes, including hepcidin, ferroportin 1 (FPN-1) and transferrin receptor (TFR)-1/2. TFR-1/2 protein expression was then evaluated in surgical specimens from 210 cases using immunohistochemistry, and we compared clinicopathological factors with TFR-1/2 expression. The mRNA expression levels of TFR-1 were significantly increased in HCC tissues compared with adjacent non-cancerous tissues (P = 0.0013), but there were no differences in other genes. High expression of TFR-1 in HCC was associated with the absence of alcohol abuse (P = 0.0467), liver cirrhosis (P < 0.0001), higher alpha-fetoprotein (AFP; P < 0.0001), smaller tumour size (P = 0.0022), poor histological differentiation (P < 0.0001) and morphological features (P < 0.0001). In contrast, high expression of TFR-2 in HCC was associated with lower AFP (P < 0.0001), well-differentiated histological grade (P < 0.0001) and morphological features (P = 0.0010). Multivariate analysis for both overall survival and recurrence-free survival indicated that high TFR-1 expression was a significant prognostic factor for poor outcome. CONCLUSIONS We found an inverse correlation of TFR-1 and TFR-2 expression in AFP and tumour differentiation. TFR-1 overexpression suggests a higher risk of recurrence and death in HCC patients following liver resection.

Abstract
Background We sought to clarify the prevalence of occult hepatitis B virus (HBV) infection (OBI) and to determine whether OBI affects the surgical outcomes in curatively resected Japanese patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). Methods A total of 257 patients with HCV-related HCC who underwent curative surgical resection were enrolled. All enrolled patients were serologically negative for HBV surface antigen and positive for HCV antibody. DNA was extracted from formalin-fixed paraffin-embedded liver tissue. OBI was determined by the HBV-DNA amplification of at least two different sets of primers by TaqMan real-time polymerase chain reaction. Surgical outcomes were evaluated according to overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS). Results OBI was identified in 15 of the 257 (5.8%) cases. In the multivariate analyses, the factors significantly correlated with OS were BMI >25 (P=0.0416), portal vein invasion (P=0.0065), and multiple tumors (P=0.0064). The only factor significantly correlated with DSS was T-stage (P=0.0275). The factors significantly correlated with DFS were liver fibrosis (P=0.0017) and T-stage (P=0.0001). The status of OBI did not show any significant correlation with OS, DSS or DFS, but a weak association with DSS (P=0.0603) was observed. Conclusions The prevalence of OBI was 5.8% in 257 cases of HCV-related HCC. Although a weak association between DSS and OBI was observed, and statistical analyses were limited by small number of OBI cases, no significant correlation between OBI and surgical outcomes was detected.

Abstract
Abstract
Background: Many factors are recognized as risks for the development of hepatocellular carcinoma (HCC) in non-B non-C (NBNC) patients. Although cigarette smoking has been recognized as one of the risk factors for HCC, the surgical outcomes and clinicopathological characteristics according to smoking habits of NBNC-HCC patients are unclear.
Methods: Consecutive cases of 83 NBNC-HCC patients who underwent curative surgical treatment for the primary lesion at Saga University Hospital were enrolled the study. The information about possibly carcinogenic factors such as alcohol abuse, diabetes mellitus, obesity and smoking habit were collected from medical records. Smoking habits were subcategorized as never, ex- and current smoker at the time of surgery. The diagnosis of non-alcoholic steatohepatitis (NASH) was based on both clinical information and pathological confirmation.
Results: Alcohol abuse, diabetes mellitus, obesity and NASH had no significant effect on the surgical outcomes. Current smoking status was strongly correlated with both overall survival (p=0.0058) and disease-specific survival (p=0.0105) by multivariate analyses. Subset analyses revealed that current smokers were significantly younger at the time of surgery (p=0.0002) and more likely to abuse alcohol (p=0.0188) and to have multiple tumors (p=0.023).
Conclusion: Current smoking habit at the time of surgery is a risk factor for poor long-term survival in NBNC-HCC patients. Current smokers tend to have multiple HCCs at a younger age than other patients.

Abstract
AIM To investigate the association between smoking habits and surgical outcomes in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) (B-HCC) and hepatitis C virus (HCV)-related HCC (C-HCC) and clarify the clinicopathological features associated with smoking status in B-HCC and C-HCC patients.
METHODS We retrospectively examined the cases of the 341 consecutive patients with viral-associated HCC (C-HCC, n = 273; B-HCC, n = 68) who underwent curative surgery for their primary lesion. We categorized smoking status at the time of surgery into never, ex- and current smoker. We analyzed the B-HCC and C-HCC groups’ clinicopathological features and surgical outcomes, i.e., disease-free survival (DFS), overall survival (OS), and disease-specific survival (DSS). Univariate and multivariate analyses were performed using a Cox proportional hazards regression model. We also performed subset analyses in both patient groups comparing the current smokers to the other patients.
RESULTS The multivariate analysis in the C-HCC group revealed that current-smoker status was significantly correlated with both OS (P = 0.0039) and DSS (P = 0.0416). In the B-HCC patients, no significant correlation was observed between current-smoker status and DFS, OS, or DSS in the univariate or multivariate analyses. The subset analyses comparing the current smokers to the other patients in both the C-HCC and B-HCC groups revealed that the current smokers developed HCC at significantly younger ages than the other patients irrespective of viral infection status.
CONCLUSION A smoking habit is significantly correlated with the overall and disease-specific survivals of patients with C-HCC. In contrast, the B-HCC patients showed a weak association between smoking status and surgical outcomes.

Abstract
AIM To investigate the prevalence, clinicopathological characteristics and surgical outcomes of occult hepatitis B virus (HBV) infection (OBI) in patients with non-B, non-C (NBNC) hepatocellular carcinoma (HCC).
METHODS This study retrospectively examined the cases of 78 NBNC patients with curative resection for HCC for whom DNA could be extracted from formalin-fixed paraffin-embedded tissue. OBI was determined by the HBV-DNA amplification of at least two different sets of primers by TaqMan real-time polymerase chain reaction. Possibly carcinogenetic factors such as alcohol abuse, diabetes mellitus, obesity and non-alcoholic steatohepatitis (NASH) were examined. Surgical outcomes were evaluated according to disease-free survival (DFS), overall survival (OS) and disease-specific survival (DSS).
RESULTS OBI was found in 27/78 patients (34.6%) with NBNC HCC. The OBI patients were significantly younger than the non-OBI cases at the time of surgery (average age 63.0 vs 68.1, P = 0.0334) and the OBI cases overlapped with other etiologies significantly more frequently compared to the non-OBI cases (P = 0.0057). OBI had no impact on the DFS, OS or DSS. Only tumor-related factors affected these surgical outcomes.
CONCLUSION Our findings indicate that OBI had no impact on surgical outcomes. The surgical outcomes of NBNC HCC depend on early tumor detection; this reconfirms the importance of a periodic medical examination for individuals who have NBNC HCC risk factors.

Abstract
The use of laparoscopic surgery in the treatment of Mirizzi syndrome is considered controversial due to the degree of technical difficulty. We herein describe the case of a 36-year-old woman who was admitted to our hospital due to appetite loss, nausea and back pain. Endoscopic retrograde cholangiography revealed a round-shaped filling defect at the confluence of the bile duct. The patient was diagnosed with Mirizzi syndrome Type II according to the Csendes classification. Before surgery, an endoscopic nasobiliary drainage tube was placed for intraoperative cholangiography. Based on the intraoperative findings, the anterior wall of Hartmann’s pouch was excised to remove the impacted gallstone. The neck portion of the gallbladder wall was then used to make a gallbladder patch, which was sutured to cover the anterior wall of the common hepatic bile duct. Laparoscopic choledochoplasty using a gallbladder patch was a technically feasible treatment for Mirizzi syndrome Type II.

Abstract
A single gallbladder with a double cystic duct is a very rare finding. MRCP showed strong suspicion of a single gallbladder with a double cystic duct and the definite diagnosis of a double cystic duct was made by ERC. Laparoscopic cholecystectomy could be successfully performed in combination with intraoperative cholangiography for double cystic duct.
Introduction A single gallbladder with a double cystic duct is a very rare finding. In addition, few cases with this rare condition are preoperatively diagnosed. However, the preoperative confirmation or suspicion of this rare condition could facilitate safe laparoscopic cholecystectomy, which is a minimally invasive therapeutic modality for gallbladder disease. We herein present a case of gallstone disease in a patient with a double cystic duct who was preoperatively diagnosed and successfully treated with laparoscopic cholecystectomy. Presentation of case A 57-year-old woman was admitted to our hospital with epigastric pain. Gallstone disease in the gallbladder and common bile duct was diagnosed by ultrasonography and computed tomography. Magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiography (ERC) revealed that the aberrant cystic duct arose from the cystic duct and communicated with the intrahepatic bile duct of the posterior segmental branch. Laparoscopic cholecystectomy was successfully performed in combination with intraoperative cholangiography. Discussion If an anomaly of the biliary duct system is not identified during surgery, it may turn out to be a bile leak. The preoperative diagnosis of a double cystic duct allows laparoscopic cholecystectomy to be performed safely in combination with intraoperative cholangiography. Conclusions A single gallbladder with double cystic duct is a very rare anomaly. However, laparoscopic surgery can be facilitated by the use of preoperative and intraoperative images.

Abstract
AIM To analyzed the correlation between smoking status and surgical outcomes in patients with non-B non-C hepatocellular carcinoma (NBNC-HCC), and we investigated the patients’ clinicopathological characteristics according to smoking status.
METHODS We retrospectively analyzed the consecutive cases of 83 NBNC-HCC patients who underwent curative surgical treatment for the primary lesion at Saga University Hospital between 1984 and December 2012. We collected information about possibly carcinogenic factors such as alcohol abuse, diabetes mellitus, obesity and smoking habit from medical records. Smoking habits were subcategorized as never, ex- and current smoker at the time of surgery. The diagnosis of non-alcoholic steatohepatitis (NASH) was based on both clinical information and pathological confirmation.
RESULTS Alcohol abuse, diabetes mellitus, obesity and NASH had no significant effect on the surgical outcomes. Current smoking status was strongly correlated with both overall survival (P = 0.0058) and disease-specific survival (P = 0.0105) by multivariate analyses. Subset analyses revealed that the current smokers were significantly younger at the time of surgery (P = 0.0002) and more likely to abuse alcohol (P = 0.0188) and to have multiple tumors (P = 0.023).
CONCLUSION Current smoking habit at the time of surgical treatment is a risk factor for poor long-term survival in NBNC-HCC patients. Current smokers tend to have multiple HCCs at a younger age than other patients.

Abstract
Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy.

Abstract
A 62-year-old woman diagnosed with gallbladder cancer exhibiting broad liver invasion and metastasis to Couinaud’s hepatic segments 4 and 8 (S4 and S8) consulted her regular doctor. Owing to the presence of liver metastases, she received treatment with gemcitabine plus S-1. After four cycles of chemotherapy, the size of the main lesion dramatically decreased and the two liver metastases disappeared. After six cycles of chemotherapy, the patient was referred to our hospital for surgical treatment. Upon admission, there was no evidence of any distant metastasis, based on a detailed radiological examination. Therefore, we performed cholecystectomy and central bisegmentectomy of the liver after obtaining the patient’s informed consent. Pathological examination demonstrated viable cancer cells with granuloma formation and calcification in the gallbladder, as well as regenerative changes without viable cancer cells in S4 and S8 of the liver. Gemcitabine plus S-1 was again administered as postoperative adjuvant chemotherapy. One and a half years after the surgery, there were no signs of recurrence. In patients selected according to their response to chemotherapy, surgical treatment might therefore be effective against gallbladder cancer with metastasis.

Abstract
A 69-year-old man was admitted to our hospital for abdominal pain. An abdominal computed tomography(CT)scan revealed pancreatictail cancer with peritoneal dissemination. We administered systemic chemotherapy consisting of S-1 and gemcitabine. After 10 courses, the peritoneal dissemination had disappeared and tumor marker levels returned to almost normal values. Thus, we considered the patient to have an effective response, so we performed a distalpancreatectomy and partial resection of the stomach, transverse colon, and left adrenal gland. Eleven months after the operation, the patient is alive with no recurrence.

Abstract
BACKGROUND/AIMS The management of hepatocellular carcinoma with hypersplenic thrombocytopenia remains controversial, because of the high surgical morbidity and mortality. Splenectomy has been reported to be useful for patients with hypersplenic thrombocytopenia, but the timing and route of splenectomy and hepatic resection remains unclear. This report evaluated the efficacy of laparoscopic surgery for simultaneous splenectomy and hepatic resection in the treatment of hepatocellular carcinoma with hypersplenic thrombocytopenia. METHODOLOGY Among 65 patients with hypersplenic thrombocytopenia who underwent hepatic resection for hepatocellular carcinoma, 20 patients underwent simultaneous splenectomy and hepatic resection. Initially, ten patients underwent the procedure by conventional laparotomy (open group) and ten patients underwent by laparoscopy (laparoscopic group). The clinicopathological results from the two groups were compared retrospectively. RESULTS The blood loss in the laparoscopic group was significantly less and the postoperative morbidity rate in the laparoscopic group was lower than that in the open group. The duration of the postoperative hospital stay in the laparoscopic group was significantly shorter and rate of patients administered interferon in the laparoscopic group was significantly higher than that in open group. CONCLUSIONS Simultaneous splenectomy and hepatic resection under laparoscopy is a safe and useful in the treatment of hepatocellular carcinoma with hypersplenic thrombocytopenia.

Abstract
BACKGROUND The aim of the present study was to investigate whether advanced age was associated with a higher rate of postoperative complications and identify the predictive factors for postoperative complications in elderly patients with hepatocellular carcinoma (HCC). METHODS Between January 2000 and December 2010, 256 patients who underwent hepatectomy for HCC were investigated. Elderly patients were defined as those aged ≥75 y. The clinicopathologic data and outcomes after hepatectomy for 64 elderly and 192 younger patients were retrospectively collected and compared. RESULTS There were no significant differences in the incidence of postoperative complications (P = 0.936) or the long-term survival after hepatectomy (P = 0.641) between the elderly and younger patients. In multivariate analysis, the estimation of physiological ability and surgical stress-preoperative risk score (PRS) was an independent risk factor for postoperative morbidity in the elderly patients (P < 0.01). Moreover, the patients were analyzed according to the PRS for the assessment of their general preoperative condition and liver damage grade based on the hepatic reserve. The rate of postoperative complications in the patients with a PRS ≥0.5 and liver damage B was significantly higher in the elderly patients (P < 0.01), whereas a PRS and liver damage grade did not affect the incidence of postoperative morbidity in the younger patients (P = 0.516). CONCLUSIONS Hepatectomy for elderly patients with HCC is feasible as well as safe, and the preoperative assessment using the estimation of physiological ability and surgical stress scoring system, combined with the liver damage grade, can help to improve the safety of this procedure for elderly HCC patients.
