Abstract
Acute normovolemic hemodilution (ANH) is a useful intraoperative blood conservation technique. However, the impact on long-term outcomes in pancreatic ductal adenocarcinoma (PDAC) remains unclear. The present study investigated the impact of ANH on long-term outcomes in patients with PDAC undergoing radical surgery. Data from 155 resectable PDAC cases were collected. Patients were categorized according to whether or not they had received intraoperative allogeneic blood transfusion (ABT) or ANH. Postoperative complications, recurrence-free survival (RFS) and disease-specific survival (DSS), before and after propensity score matching (PSM), were compared among patients who did and did not receive ANH. A total of 44 patients (28.4%) were included in the ANH group and 30 patients (19.4%) were included in the ABT group; 81 (52.3%) patients, comprising the standard management (STD) group, received neither ANH nor ABT. The ABT group had the worst prognosis among them. Before PSM, ANH was significantly associated with decreased RFS (P=0.043) and DSS (P=0.029) compared with the STD group before applying Bonferroni correction; however, no significant difference was observed after applying Bonferroni correction. Cox regression analysis identified ANH as an independent prognostic factor for RFS [relative risk (RR), 1.696; P=0.019] and DSS (RR, 1.876; P=0.009). After PSM, the ANH group exhibited less favorable RFS [median survival time (MST), 12.1 vs. 18.1 months; P=0.097] and DSS (MST, 32.1 vs. 50.5 months; P=0.097) compared with the STD group; however, these differences were not statistically significant. In conclusion, while ANH was not as harmful as ABT, it exhibited potentially more negative effects on long-term postoperative outcomes in PDAC than STD.

Abstract
A 72-year-old man was referred to our hospital for the examination of a pancreatic head mass. Abdominal computed tomography revealed a contrasted 8-cm-diameter tumor extending from the dorsal pancreatic head to the porta hepatis. The preoperative diagnosis was challenging due to the absence of specific imaging findings and the inability to perform a biopsy. Positron emission tomography/computed tomography and diffusion-weighted imaging suggested a malignant tumor originating from the organs surrounding the pancreatic head. Subtotal stomach-preserving pancreaticoduodenectomy with regional lymph node dissection was performed, as dissection from the pancreatic head proved unfeasible. Pathological examination identified the tumor as an enlarged lymph node consisting of pleomorphic large cells forming clusters, positive for follicular dendritic cell markers cluster of differentiation (CD) 21 and CD23. No evidence of tumor capsule infiltration, other organ infiltration, or metastasis to other lymph nodes was observed. The final diagnosis was nodal follicular dendritic cell sarcoma (FDCS) originating from the pancreatic head lymph nodes. No recurrence occurred at 3 years postoperatively with no postoperative treatment. Intraperitoneal nodal FDCS is extremely rare, and occasionally, it can lead to postoperative recurrence and progression. It is crucial to differentiate neoplastic lymph node enlargement around the pancreatic head from nodal FDCS.

Abstract
The liver and pancreas work together to recover homeostasis after hepatectomy. This study aimed to investigate the effect of liver resection volume on the pancreas. We collected clinical data from 336 living liver donors. They were categorized into left lateral sectionectomy (LLS), left lobectomy, and right lobectomy (RL) groups. Serum pancreatic enzymes were compared among the groups. Serum amylase values peaked on postoperative day (POD) 1. Though they quickly returned to preoperative levels on POD 3, 46% of cases showed abnormal values on POD 7 in the RL group. Serum lipase levels were highest at POD 7. Lipase values increased 5.7-fold on POD 7 in the RL group and 82% of cases showed abnormal values. The RL group's lipase was twice that of the LLS group. A negative correlation existed between the remnant liver volume and amylase (r = - 0.326)/lipase (r = - 0.367) on POD 7. Furthermore, a significant correlation was observed between POD 7 serum bilirubin and amylase (r = 0.379)/lipase (r = 0.381) levels, indicating cooccurrence with liver and pancreatic strain. Pancreatic strain due to hepatectomy occurs in a resection/remnant liver volume-dependent manner. It would be beneficial to closely monitor pancreatic function in patients undergoing a major hepatectomy.

Abstract
BACKGROUND Peripancreatic bacterial contamination (PBC) is a critical factor contributing to the development of clinically relevant postoperative pancreatic fistula (CR-POPF) following pancreaticoduodenectomy (PD). Controlling pathogenic bacteria is essential in preventing CR-POPF; however, the precise relationship between specific bacteria and CR-POPF remains unclear. This study aimed to investigate the relationship between PBC and CR-POPF after PD, with a focus on identifying potentially causative bacteria. METHODS This prospective observational study enrolled 370 patients who underwent PD. Microbial cultures were routinely collected from peripancreatic drain fluid on postoperative days (PODs) 1, 3, and 6. Predictive factors for CR-POPF and the bacteria involved in PBC were investigated. RESULTS CR-POPF occurred in 86 (23.2%) patients. In multivariate analysis, PBC on POD1 (Odds ratio [OR] = 3.59; P = 0.005) was one of the main independent predictive factors for CR-POPF, while prophylactic use of antibiotics other than piperacillin/tazobactam independently influenced PBC on POD1 (OR = 2.95; P = 0.010). Notably, Enterococcus spp., particularly Enterococcus faecalis, were significantly isolated from PBC in patients with CR-POPF compared to those without CR-POPF on PODs 1 and 3 (P < 0.001), and they displayed high resistance to all cephalosporins. CONCLUSIONS Early PBC plays a pivotal role in the development of CR-POPF following PD. Prophylactic antibiotic administration, specifically targeting Enterococcus faecalis, may effectively mitigate early PBC and subsequently reduce the risk of CR-POPF. This research sheds light on the importance of bacterial control strategies in preventing CR-POPF after PD.

Abstract
OBJECTIVES We aimed to predict in vitro chemosensitivity assay results from computed tomography (CT) images by applying deep learning (DL) to optimize chemotherapy for pancreatic ductal adenocarcinoma (PDAC). MATERIALS AND METHODS Preoperative enhanced abdominal CT images and the histoculture drug response assay (HDRA) results were collected from 33 PDAC patients undergoing surgery. Deep learning was performed using CT images of both the HDRA-positive and HDRA-negative groups. We trimmed small patches from the entire tumor area. We established various prediction labels for HDRA results with 5-fluorouracil (FU), gemcitabine (GEM), and paclitaxel (PTX). We built a predictive model using a residual convolutional neural network and used 3-fold cross-validation. RESULTS Of the 33 patients, effective response to FU, GEM, and PTX by HDRA was observed in 19 (57.6%), 11 (33.3%), and 23 (88.5%) patients, respectively. The average accuracy and the area under the receiver operating characteristic curve (AUC) of the model for predicting the effective response to FU were 93.4% and 0.979, respectively. In the prediction of GEM, the models demonstrated high accuracy (92.8%) and AUC (0.969). Likewise, the model for predicting response to PTX had a high performance (accuracy, 95.9%; AUC, 0.979). CONCLUSIONS Our CT patch-based DL model exhibited high predictive performance in projecting HDRA results. Our study suggests that the DL approach could possibly provide a noninvasive means for the optimization of chemotherapy.

Abstract
BACKGROUND Extramural vascular invasion (EMVI) and tumor deposits (TD) are poor prognostic factors in rectal cancer (RC), especially when resistant to neoadjuvant chemotherapy (NAC). We aimed to define differential expression in NAC responders and non-responders with concomitant EMVI and TD. METHODS From 52 RC surgical patients, post-NAC resected specimens were extracted, comprising two groups: cases with residual EMVI and TD (NAC-resistant) and cases without (NAC-effective). Proteomic analysis was conducted to define differential protein expression in the two groups. To validate the findings, immunohistochemistry was performed in another cohort that included 58 RC surgical patients. Based on the findings, chemosensitivity and prognosis were compared. RESULTS The NAC-resistant group was associated with a lower 3-year disease-free survival rate than the NAC-effective group (p = 0.041). Discriminative proteins in the NAC-resistant group were highly associated with the sulfur metabolism pathway. Among these pathway constituents, selenium-binding protein 1 (SELENBP1) expression in the NAC-resistant group decreased to less than one-third of that of the NAC-effective group. Immunohistochemistry in another RC cohort consistently validated the relationship between decreased SELENBP1 and poorer NAC sensitivity, in both pre-NAC biopsy and post-NAC surgery specimens. Furthermore, decrease in SELENBP1 was associated with a lower 3-year disease-free survival rate (p = 0.047). CONCLUSIONS We defined one of the differentially expressed proteins in NAC responders and non-responders, concomitant with EMVI and TD. SELENBP1 was suspected to contribute to NAC resistance and poor prognosis in RC.

Abstract
A 65-year-old woman underwent living-donor liver transplantation (left-lobe graft: GWRW ratio, 0.54) for cirrhosis caused by autoimmune hepatitis. At 68 years, she was diagnosed with obstructive cholangitis due to stricture during a hepaticojejunostomy following impaired liver function. Endoscopic balloon dilation of anastomosis and placement of a plastic stent resulted in improved liver function. However, at 72 years, the patient experienced a flare-up of liver damage. The plastic stent had fallen out, and although endoscopic stenotic dilation was attempted, the anastomotic site was obstructed completely. Therefore, recanalization of the hepaticojejunostomy was attempted using a rendezvous technique. A percutaneous transhepatic biliary drainage tube was inserted through the B3 bile duct, and the complete obstructed anastomosis was confirmed by percutaneous transhepatic and transjejunal approaches. The anastomosis was reopened by excising the scarred tissues from the jejunal side using a 1.5-mm high-frequency knife. A 14-Fr. catheter for the internal fistula tube was percutaneously placed at the opened anastomosis to achieve anastomotic site recanalization. The patient's liver damage improved after the re-internalization, and no symptom recurrence such as obstructive cholangitis developed for 1 year. There are few reports of recanalization of the hepaticojejunostomy with a high-frequency knife. Herein, we report the case with a literature review.

Abstract
Perineural invasion (PNI) is a characteristic invasion pattern of distal cholangiocarcinoma (DCC). Conventional histopathologic examination is a challenging approach to analyze the spatial relationship between cancer and neural tissue in full-thickness bile duct specimens. Therefore, we used a tissue clearing method to examine PNI in DCC with three-dimensional (3D) structural analysis. The immunolabeling-enabled 3D imaging of solvent-cleared organs method was performed to examine 20 DCC specimens from five patients and 8 non-neoplastic bile duct specimens from two controls. The bile duct epithelium and neural tissue were labeled with CK19 and S100 antibodies, respectively. Two-dimensional hematoxylin/eosin staining revealed only PNI around thick nerve fibers in the deep layer of the bile duct, whereas PNI was not identified in the superficial layer. 3D analysis revealed that the parts of DCC closer to the mucosa exhibited more nerves than the normal bile duct. The nerve fibers were continuously branched and connected with thick nerve fibers in the deep layer of the bile duct. DCC formed a tubular structure invading from the epithelium and extending around thin nerve fibers in the superficial layer. DCC exhibited continuous infiltration around the thick nerve fibers in the deep layer. This is the first study using a tissue clearing method to examine the PNI of DCC, providing new insights into the underlying mechanisms.

Abstract
Lymphatic fluid drains from the liver via the periportal lymphatic, hepatic venous lymphatic, and superficial lymphatic systems. We performed a postmortem study to clarify the three-dimensional structure and flow dynamics of the human hepatic venous lymphatic system, as it still remains unclear. Livers were excised whole from three human cadavers, injected with India ink, and sliced into 1-cm sections from which veins were harvested. The distribution of lymphatic vessels was observed in 5 μm sections immunostained for lymphatic and vascular markers (podoplanin and CD31, respectively) using light microscopy. Continuity and density of lymphatic vessel distribution were assessed in en-face whole-mount preparations of veins using stereomicroscopy. The structure of the external hepatic vein wall was assessed with scanning electron microscopy (SEM). The lymphatic dynamics study suggested that lymphatic fluid flows through an extravascular pathway around the central and sublobular veins. A lymphatic vessel network originates in the wall of sublobular veins, with a diameter greater than 110 μm, and the peripheral portions of hepatic veins and continues to the inferior vena cava. The density distribution of lymphatic vessels is smallest in the peripheral portion of the hepatic vein (0.03%) and increases to the proximal portion (0.22%, p = 0.012) and the main trunk (1.01%, p < 0.001), correlating positively with increasing hepatic vein diameter (Rs = 0.67, p < 0.001). We revealed the three-dimensional structure of the human hepatic venous lymphatic system. The results could improve the understanding of lymphatic physiology and liver pathology.

Abstract
BACKGROUND Evolutionary cancer has a supply mechanism to satisfy higher energy demands even in poor-nutrient conditions. Metabolic reprogramming is essential to supply sufficient energy. The relationship between metabolic reprogramming and the clinical course of pancreatic ductal adenocarcinoma (PDAC) remains unclear. We aimed to clarify the differences in metabolic status among PDAC patients. METHODS We collected clinical data from 128 cases of resectable PDAC patients undergoing surgery. Sixty-three resected tissues, 15 tissues from the low carbohydrate antigen 19-9 (CA19-9), 38-100 U/mL, and high CA19-9, > 500 U/mL groups, and 33 non-tumor control parts, were subjected to tandem mass spectrometry workflow to systematically explore metabolic status. Clinical and proteomic data were compared on the most used PDAC biomarker, preoperative CA19-9 value. RESULTS Higher CA19-9 levels were clearly associated with higher early recurrence (p < 0.001), decreased RFS (p < 0.001), and decreased DSS (p = 0.025). From proteomic analysis, we discovered that cancer evolution-related as well as various metabolism-related pathways were more notable in the high group. Using resected tissue immunohistochemical staining, we learned that high CA19-9 PDAC demonstrated aerobic glycolysis enhancement, yet no decrease in protein synthesis. We found a heterogeneity of various metabolic processes, including carbohydrates, proteins, amino acids, lipids, and nucleic acids, between the low and the high groups, suggesting differences in metabolic adaptive capacity. CONCLUSIONS Our study found metabolic adaptation differences among PDAC cases, pertaining to both cancer evolution and the prognosis. CA19-9 can help estimate the metabolic adaptive capacity of energy supply for PDAC evolution.

Abstract
Background Emphysematous pancreatitis is acute pancreatitis associated with emphysema based on imaging studies and has been considered a subtype of necrotizing pancreatitis. Although some recent studies have reported the successful use of conservative treatment, it is still considered a serious condition. Computed tomography (CT) scan is useful in identifying emphysema associated with acute pancreatitis; however, whether the presence of emphysema correlates with the severity of pancreatitis remains controversial. In this study, we managed two cases of severe acute pancreatitis complicated with retroperitoneal emphysema successfully by treatment with lavage and drainage. Case presentation Case 1: A 76-year-old man was referred to our hospital after being diagnosed with acute pancreatitis. At post-admission, his abdominal symptoms worsened, and a repeat CT scan revealed increased retroperitoneal gas. Due to the high risk for gastrointestinal tract perforation, emergent laparotomy was performed. Fat necrosis was observed on the anterior surface of the pancreas, and a diagnosis of acute necrotizing pancreatitis with retroperitoneal emphysema was made. Thus, retroperitoneal drainage was performed. Case 2: A 50-year-old woman developed anaphylactic shock during the induction of general anesthesia for lumbar spine surgery, and peritoneal irritation symptoms and hypotension occurred on the same day. Contrast-enhanced CT scan showed necrotic changes in the pancreatic body and emphysema surrounding the pancreas. Therefore, she was diagnosed with acute necrotizing pancreatitis with retroperitoneal emphysema, and retroperitoneal cavity lavage and drainage were performed. In the second case, the intraperitoneal abscess occurred postoperatively, requiring time for drainage treatment. Both patients showed no significant postoperative course problems and were discharged on postoperative days 18 and 108, respectively. Conclusion Acute pancreatitis with emphysema from the acute phase highly indicates severe necrotizing pancreatitis. Surgical drainage should be chosen without hesitation in necrotizing pancreatitis with emphysema from early onset.

Abstract
INTRODUCTION There have been reports about robotic surgery for rectal cancer with chemoradiotherapy (CRT), but only a few studies have compared the use of robotic surgery with and without neoadjuvant chemotherapy (NAC). The aim of our study was to compare the perioperative outcomes of robotic surgery with and without NAC for lower rectal cancer and to examine the effects of NAC on robotic surgery. METHODS From January 2016 to July 2021, we compared the short-term outcomes of 45 patients who did not undergo NAC and 55 patients who underwent NAC. RESULTS The rate of sphincter-preserving surgeries was higher in the NAC group than in the non-NAC group (P = .024). The total operative time was significantly longer in the NAC group than in the non-NAC group (P < .001). The rate of lateral lymph node dissection was significantly higher in the NAC group than in the non-NAC group (P < .001). No significant differences were identified in the rate of incisional surgical site infections (SSI), organ/space SSI postoperative bleeding, small bowel obstruction, anastomotic leakage, urinary dysfunction, or urinary infections between the groups. There were eight incidences of lateral lymph node metastasis (15%) and two cases with positive resection margins (4.0%) in the NAC group. CONCLUSIONS Robotic surgery after NAC has few complications and a higher sphincter-preserving rate that without NAC.

Abstract
Background The differential diagnosis between gallbladder cancer (GBC) and xanthogranulomatous cholecystitis (XGC) remains quite challenging, and can possibly lead to improper surgery. This study aimed to distinguish between XGC and GBC by combining computed tomography (CT) images and deep learning (DL) to maximize the therapeutic success of surgery. Methods We collected a dataset, including preoperative CT images, from 28 cases of GBC and 21 XGC patients undergoing surgery at our facility. It was subdivided into training and validation (n = 40), and test (n = 9) datasets. We built a CT patch‐based discriminating model using a residual convolutional neural network and employed 5‐fold cross‐validation. The discriminating performance of the model was analyzed in the test dataset. Results Of the 40 patients in the training dataset, GBC and XGC were observed in 21 (52.5%), and 19 (47.5%) patients, respectively. A total of 61 126 patches were extracted from the 40 patients. In the validation dataset, the average sensitivity, specificity, and accuracy were 98.8%, 98.0%, and 98.5%, respectively. Furthermore, the area under the receiver operating characteristic curve (AUC) was 0.9985. In the test dataset, which included 11 738 patches, the discriminating accuracy for GBC patients after neoadjuvant chemotherapy (NAC) (n = 3) was insufficient (61.8%). However, the discriminating model demonstrated high accuracy (98.2%) and AUC (0.9893) for cases other than those receiving NAC. Conclusion Our CT‐based DL model exhibited high discriminating performance in patients with GBC and XGC. Our study proposes a novel concept for selecting the appropriate procedure and avoiding unnecessary invasive measures.

Abstract
Preoperatively accurate evaluation of risk for early postoperative recurrence contributes to maximizing the therapeutic success for intrahepatic cholangiocarcinoma (iCCA) patients. This study aimed to investigate the potential of deep learning (DL) algorithms for predicting postoperative early recurrence through the use of preoperative images. We collected the dataset, including preoperative plain computed tomography (CT) images, from 41 patients undergoing curative surgery for iCCA at multiple institutions. We built a CT patch-based predictive model using a residual convolutional neural network and used fivefold cross-validation. The prediction accuracy of the model was analyzed. We defined early recurrence as recurrence within a year after surgical resection. Of the 41 patients, early recurrence was observed in 20 (48.8%). A total of 71,081 patches were extracted from the entire segmented tumor area of each patient. The average accuracy of the ResNet model for predicting early recurrence was 98.2% for the training dataset. In the validation dataset, the average sensitivity, specificity, and accuracy were 97.8%, 94.0%, and 96.5%, respectively. Furthermore, the area under the receiver operating characteristic curve was 0.994. Our CT-based DL model exhibited high predictive performance in projecting postoperative early recurrence, proposing a novel insight into iCCA management.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy and total mesorectal excision compose the standard of care for rectal cancer in multiple guidelines. However, neoadjuvant chemoradiotherapy has not exhibited clear survival benefits but rather has led to an increase in adverse events. Conversely, neoadjuvant chemotherapy is expected to prevent adverse events caused by radiation, yet this treatment is still controversial. OBJECTIVE The purpose of this study was to evaluate the feasibility and efficacy of S-1 and oxaliplatin neoadjuvant chemotherapy together with total mesorectal excision for resectable locally advanced rectal cancer. DESIGN The study was a prospective, single-arm phase II trial. SETTINGS The study was conducted at multiple institutions. PATIENTS Fifty-eight patients with resectable locally advanced rectal cancer were enrolled. INTERVENTION Three cycles of S-1 and oxaliplatin were administered before surgery. S-1 was administered orally at 80 mg/m2 per day for 14 consecutive days, followed by a 7-day resting period. Oxaliplatin was given intravenously on the first day at a dose of 130 mg/m2 per day. The duration of 1 cycle was considered to be 21 days. Total mesorectal excision with bilateral lymph node dissection was carried out after neoadjuvant chemotherapy. MAIN OUTCOME MEASURES The study was designed to detect the feasibility and efficacy of S-1 and oxaliplatin as neoadjuvant chemotherapy. RESULTS The completion rate of 3 courses of S-1 and oxaliplatin as neoadjuvant chemotherapy was 94.8% (55/58). The reasons for discontinuation were thrombocytopenia (3.4%) and liver injury (1.7%). The most common severe (grade ≥3) adverse effect of neoadjuvant chemotherapy was thrombocytopenia (3.4%). There were no severe adverse clinical symptoms. Consequently, R0 resection was achieved in 51 (98.1%) of 52 patients. Pathologic complete response occurred in 10 patients (19.2%). LIMITATIONS This was a single-arm, nonrandomized phase II study. CONCLUSIONS The combination of S-1 and oxaliplatin neoadjuvant chemotherapy and total mesorectal excision is a feasible and promising treatment option for resectable locally advanced rectal cancer.

UN ESTUDIO PROSPECTIVO MULTICNTRICO FASE II SOBRE LA FACTIBILIDAD Y EFICACIA DE LA QUIMIOTERAPIA NEOADYUVANTE SCON OXALIPLATINO PARA EL CNCER DE RECTO LOCALMENTE AVANZADO ANTECEDENTES:La quimiorradioterapia neoadyuvante y la escisión mesorrectal total constituyen el estándar de atención para el cáncer de recto en varias guías. Sin embargo, la quimiorradioterapia neoadyuvante no ha mostrado beneficios claros en la sobrevida, pero si ha creado un aumento de eventos adversos. Por otro lado, se espera que la quimioterapia neoadyuvante prevenga los eventos adversos asociados a la radiación, aunque este tratamiento sigue siendo controvertido.OBJETIVO:Evaluar la factibilidad y eficacia de la quimioterapia neoadyuvante S-1 con oxaliplatino en conjunto con la escisión mesorrectal total para el cáncer de recto localmente avanzado resecable.DISEÑO:El estudio fue un ensayo prospectivo fase II de brazo único.AMBITO:Estudio realizado en múltiples instituciones.PACIENTES:Se incluyeron 58 pacientes con cáncer de recto localmente avanzado resecable.INTERVENCIÓN:Se administraron tres ciclos de S-1 con oxaliplatino antes de la cirugía. Se administró S-1 por vía oral a 80 mg / m2 / día durante 14 días consecutivos, seguido de un período de descanso de 7 días. El oxaliplatino se administró por vía intravenosa el primer día a una dosis de 130 mg / m2 / día. Se consideró la duración de un ciclo de 21 días. Posterior a la quimioterapia neoadyuvante se realizó la excisión total mesorrectal con disección ganglionar bilateral.PRINCIPALES VARIABLES EVALUDADAS:El estudio fue diseñado para conocer la factibilidad y eficacia de S-1 con oxaliplatino como quimioterapia neoadyuvante.RESULTADOS:La tasa de conclusión con tres ciclos de S-1 con oxaliplatino como quimioterapia neoadyuvante fue del 94,8% (55/58). Los motivos de interrupción fueron trombocitopenia (3,4%) y daño hepático (1,7%). El efecto adverso grave más común (grado ≥ 3) de la quimioterapia neoadyuvante fue la trombocitopenia (3,4%). No hubo síntomas clínicos adversos graves. Como resultado, la resección R0 se logró en 51 de 52 pacientes (98,1%). Una respuesta patológica completa se obtuvo en 10 pacientes (19,2%).LIMITACIONES:Fue un estudio de fase II no aleatorizado de un solo brazo.CONCLUSIONES:La combinación de S-1 con oxaliplatino como quimioterapia neoadyuvante y escisión mesorrectal total es factible y es una opción de tratamiento prometedora para el cáncer de recto localmente avanzado resecable.

Abstract
Massive intraoperative blood loss (IBL) negatively influence outcomes after surgery for pancreatic ductal adenocarcinoma (PDAC). However, few data or predictive models are available for the identification of patients with a high risk for massive IBL. This study aimed to build a model for massive IBL prediction using a decision tree algorithm, which is one machine learning method. One hundred and seventy-five patients undergoing curative surgery for resectable PDAC at our facility between January 2007 and October 2020 were allocated to training (n = 128) and testing (n = 47) sets. Using the preoperatively available data of the patients (34 variables), we built a decision tree classification algorithm. Of the 175 patients, massive IBL occurred in 88 patients (50.3%). Binary logistic regression analysis indicated that alanine aminotransferase and distal pancreatectomy were significant predictors of massive IBL occurrence with an overall correct prediction rate of 70.3%. Decision tree analysis automatically selected 14 predictive variables. The best predictor was the surgical procedure. Though massive IBL was not common, the outcome of patients with distal pancreatectomy was secondarily split by glutamyl transpeptidase. Among patients who underwent PD (n = 83), diabetes mellitus (DM) was selected as the variable in the second split. Of the 21 patients with DM, massive IBL occurred in 85.7%. Decision tree sensitivity was 98.5% in the training data set and 100% in the testing data set. Our findings suggested that a decision tree can provide a new potential approach to predict massive IBL in surgery for resectable PDAC.

Abstract
Background Resectable pancreatic ductal adenocarcinoma (R-PDAC) often recurs early after radical resection, which is associated with poor prognosis. Predicting early recurrence preoperatively is useful for determining the optimal treatment. Patients and methods One hundred and seventy-eight patients diagnosed with R-PDAC on computed tomography (CT) imaging and undergoing radical resection at Hirosaki University Hospital from 2005 to 2019 were retrospectively analyzed. Patients with recurrence within 6 months after resection formed the early recurrence (ER) group, while other patients constituted the non-early recurrence (non-ER) group. Early recurrence prediction score (ERP score) was developed using preoperative parameters. Results ER was observed in 45 patients (25.3%). The ER group had significantly higher preoperative CA19-9 (p = 0.03), serum SPan-1 (p = 0.006), and CT tumor diameter (p = 0.01) compared with the non-ER group. The receiver operating characteristic (ROC) curve analysis identified cutoff values for CA19-9 (133 U/mL), SPan-1 (78.2 U/mL), and preoperative tumor diameter (23 mm). When the parameter exceeded the cutoff level, 1 point was given, and the total score of the three factors was defined as the ERP score. The group with an ERP score of 3 had postoperative recurrence-free survival (RFS) of 5.5 months (95% CI 3.02–7.98). Multivariate analysis for ER-related perioperative and surgical factors identified ERP score of 3 [odds ratio (OR) 4.63 (95% CI 1.82–11.78), p = 0.0013] and R1 resection [OR 3.20 (95% CI 1.01–10.17), p = 0.049] as independent predictors of ER. Conclusions For R-PDAC, ER could be predicted by the scoring system using preoperative serum CA19-9 and SPan-1 levels and CT tumor diameter, which may have great significance in identifying patients with poor prognoses and avoiding unnecessary surgery.

Abstract
OBJECTIVE We aimed to investigate the real impact of allogeneic red blood cell transfusion (ABT) on postoperative outcomes in resectable pancreatic ductal adenocarcinoma (PDAC) patients. METHODS Of 128 patients undergoing resectable PDAC surgery at our facility, 24 (18.8%) received ABT. Recurrence-free survival (RFS) and disease-specific survival (DSS), before and after propensity score matching (PSM), were compared among patients who did and did not receive ABT. RESULTS In the entire cohort, ABT was significantly associated with decreased RFS (P = 0.002) and DSS (P = 0.014) before PSM. Cox regression analysis identified ABT (risk ratio, 1.884; 95% confidence interval, 1.015-3.497; P = 0.045) as an independent prognostic factor for RFS. Univariate and multivariate analysis identified preoperative hemoglobin value, preoperative total bilirubin value, and intraoperative blood loss as significant independent risk factors for ABT. Using these 3 variables, PSM analysis created 16 pairs of patients. After PSM, the ABT group had significantly poorer RFS rates than the non-ABT group (median, 9.8 vs 15.8 months, P = 0.022). Similar tendencies were found in DSS rates (median, 19.4 vs 40.0 months, P = 0.071). CONCLUSIONS This study revealed certain negative effects of intraoperative ABT on postoperative survival outcomes in patients with resectable PDAC.

Abstract
Pancreatic ductal adenocarcinoma (PDAC), with its extremely poor prognosis, presents a substantial health problem worldwide. Outcomes have improved thanks to progress in surgical technique, chemotherapy, pre-/postoperative management, and centralization of patient care to high-volume centers. However, our goals are yet to be met. Recently, exome sequencing using PDAC surgical specimens has demonstrated that the most frequently altered genes were the axon guidance genes, indicating involvement of the nervous system in PDAC carcinogenesis. Moreover, perineural invasion has been widely identified as one poor prognostic factor. The combination of innovative technologies and extensive clinician experience with the nervous system come together here to create a new treatment option. However, evidence has emerged that suggests that the relationship between cancer and nerves in PDAC, the underlying mechanism, is not fully understood. In an attempt to tackle this lethal cancer, this review summarizes the anatomy and physiology of the pancreas and discusses the role of the nervous system in the pathophysiology of PDAC.

Abstract
Background Intra-ampullary papillary-tubular neoplasm (IAPN) has been classified as a Vater papillary tumor. The prognosis of IAPN is generally relatively good. Here, we describe a patient with a mucinous adenocarcinoma cluster in the Vater papilla of IAPN origin. Clinical presentation The patient was a 66-year-old man who was admitted to our hospital after a diagnosis of pancreatic head carcinoma based on a pancreatic duct dilatation found on abdominal ultrasound. CT showed a 40 mm lesion in the pancreatic head and expansion of the main pancreatic duct to a maximum diameter of 9 mm on the caudal side of the lesion. The extrahepatic bile duct had also expanded to a maximum diameter of 8 mm. PET/CT showed fluorodeoxyglucose (FDG) accumulation of SUVmax 6.02 that corresponded to the tumor in the pancreatic head, though it did not suggest distant metastasis. The patient was diagnosed with pancreatic head carcinoma T3 N0 M0 Stage IIA and underwent a pancreaticoduodenectomy. Pathology indicated that the tumor in the pancreatic head was a benign inflammatory lesion. On the other hand, the papillotubular tumor pervading the lumen in the duodenal papillary common channel met the criteria for IAPN, and a mucinous adenocarcinoma cluster found in the surrounding stroma suggested malignant transformation of IAPN. No metastasis to lymph nodes was demonstrated. With regard to the mucus phenotype of each lesion, the IAPN was MUC2 and MUC5AC positive, while the mucinous adenocarcinoma was MUC2-positive and MUC5AC-negative. In addition, CD10 was negative in both lesions, suggesting that mucus transformation from the gastric type to the intestinal type was a key element. A blood test 10 months after surgery showed increased CA19-9 (105 U/mL) and CEA (7.1 ng/mL). Abdominal CT showed multiple cystoid nodes in the liver, which were diagnosed as multiple liver metastases of mucinous adenocarcinoma transformed from the IAPN. Conclusions We reported a case with IAPN that developed in the Vater papilla, which took an extremely malignant course. IAPN generally has a good prognosis, but it is important to understand that a malignant course may occur.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is highly malignant. While cancers in other organs have shown clear improvements in 5-year survival, the 5-year survival rate of pancreatic cancer is approximately 10%. Early relapse and metastasis are not uncommon, making it difficult to achieve an acceptable prognosis even after complete surgical resection of the pancreas. Studies have been performed on various treatments to improve the prognosis of PDAC, and multidisciplinary approaches including non-surgical treatments have led to gradual improvement. In the present literature review, we have described the significance of anatomical and biological resectability criteria, the concept of R0 resection in surgical treatment, the feasibility of minimally invasive surgery, the remarkable development of perioperative chemotherapy, the effectiveness of conversion surgery for unresectable PDAC, and ongoing challenges in PDAC treatment. We also provide an essential update on these subjects by focusing on recent trends and topics.

Abstract
PURPOSE There are no reports showing the significance and effective range of dissection for patients with lateral lymph node metastasis (LLNM). This study aimed to investigate the indications for lateral lymph node dissection (LLND) in patients with LLNM based on prognostic factors and recurrence types. METHODS We reviewed 379 patients with advanced rectal cancer who were treated with total mesorectal excision plus LLND. We analyzed background factors and survival times of patients who had LLNM to determine prognostic factors and recurrence types. RESULTS Pathological LLNM occurred in 44 (11.6%). Among patients with LLNM, the predictors of poor prognoses, according to univariate analysis, were > 3 node metastases, the presence of node metastasis on both sides, and spreading beyond the internal iliac lymph nodes. Moreover, LLNM beyond the internal iliac region was found to be an independent prognostic risk factor. Twenty-eight of the 44 patients with lateral lymph node metastasis (64%) relapsed, 22 of whom had distant metastases and 11 of whom experienced local recurrences. Among the latter group, nine (20%) and two (5%) had recurrences in the central and lateral pelvis, respectively. CONCLUSION The therapeutic benefit of resection was high, especially in patients with ≤ 3 positive lateral lymph nodes, one-sided bilateral lymph node areas, and positive nodes localized near the internal iliac artery.

Abstract
Hepatic ischemia-reperfusion (I/R) injury is a major problem in liver transplantation (LT). Although hepatocyte cell death is the initial event in hepatic I/R injury, the underlying mechanism remains unclear. In the present study, we retrospectively analyzed the clinical data of 202 pediatric living donor LT and found that a high serum ferritin level, a marker of iron overload, of the donor is an independent risk factor for liver damage after LT. Since ferroptosis has been recently discovered as an iron-dependent cell death that is triggered by a loss of cellular redox homeostasis, we investigated the role of ferroptosis in a murine model of hepatic I/R injury, and found that liver damage, lipid peroxidation, and upregulation of the ferroptosis marker Ptgs2 were induced by I/R, and all of these manifestations were markedly prevented by the ferroptosis-specific inhibitor ferrostatin-1 (Fer-1) or α-tocopherol. Fer-1 also inhibited hepatic I/R-induced inflammatory responses. Furthermore, hepatic I/R injury was attenuated by iron chelation by deferoxamine and exacerbated by iron overload with a high iron diet. These findings demonstrate that iron overload is a novel risk factor for hepatic I/R injury in LT, and ferroptosis contributes to the pathogenesis of hepatic I/R injury.

Abstract
BACKGROUND The relationship between smoking cessation and weight gain is well recognized. Examining the link between smoking cessation and weight gain in donor candidates for living donor liver transplantation (LDLT) is an important topic because of the influence of weight gain on the liver. This study assessed body weight (BW) changes after smoking cessation in donor candidates for LDLT. METHODS The 27 donor candidates were retrospectively analyzed. The smoking status was determined based on questionnaires administered at the initial presentation, and the candidates were divided into 2 groups: recent quitters and nonsmokers. The changes in BW were compared between the groups. RESULTS The recent quitters group included 10 (37.0%) candidates, and the nonsmokers group included 17 (63.0%). In the nonsmokers group, 1 candidate had gained weight since the initial presentation. In contrast, in the recent quitters group, 70.0% of candidates had gained weight since the initial presentation (P < .01). The change in BW from the initial presentation was greater in recent quitters than in nonsmokers (+1.6 kg [+2.4%] vs -0.5 kg [-0.9%]; P < .01). Two candidates in the recent quitters group gained ≥ 5 kg [8%] of weight. One of these 2 candidates was judged to be in a donor-inadequate status because of the appearance of fatty liver. CONCLUSIONS Weight gain due to smoking cessation was observed in donor candidates for LDLT. The amount of weight gain after smoking cessation is highly individualized, so everyone concerned with LDLT must be alert to its potential development.

Abstract
BACKGROUND & AIMS The relationship between smoking cessation and weight gain is well recognized. However, there is no data currently available on the effect of smoking cessation on weight gain in patients with malignancy. The aim of this study was to clarify the body weight (BW) change after smoking cessation in patients with malignancy. METHODS We retrospectively analyzed 159 subjects who underwent hepatobiliopancreatic surgery. The smoking status was determined using questionnaires administered at the initial presentation, and the candidates were divided into two groups: recent quitters and nonsmokers. The change in the BW was compared between these two groups. RESULTS There were 134 subjects with malignant disease (84.3%), with a median age of 68 (range: 26-84) years. In the nonsmoker group, 28 of 116 subjects (24.1%) gained weight between the initial presentation and admission. In the recent quitter group, 12 of 18 subjects (66.7%) gained weight in the same period (P < 0.01). Regarding the change in the BW from the initial presentation, recent quitters gained more weight than nonsmokers (+1.7 kg [+2.7%] vs. -1.0 kg [-2.0%], P < 0.01). Furthermore, the improvement from the initial presentation was seen in a higher percentage of recent quitters than nonsmokers with respect to Onodera's prognostic nutritional index (61.1% vs. 36.2%, P = 0.04) and the controlling nutritional status score (38.9% vs. 19.3%, P = 0.07). CONCLUSIONS Weight gain due to smoking cessation was observed even in patients with hepatobiliopancreatic malignancy.

Abstract
A 34-year-old man was diagnosed with familial adenomatous polyposis(FAP)in September 2011, and he underwent endoscopic mucosal resection(EMR)due to multiple polyps in the duodenum and small intestine. Three months later, duodenal cancer was found, and he underwent a subsequent EMR. The pathological findings showed residual cancer cells in the lateral margin; therefore, EMR was performed again. Total colectomy and partial resection of the small intestine was performed in December 2012. Esophagogastroduodenoscopy(EGD)was then performed every 3-6 months, and EMR was performed 4 times. We followed up the patient annually, starting 2014. In January 2016, recurrence of the duodenal cancer was found; therefore, he underwent a pancreatoduodenectomy. The pathological diagnosis was adenocarcinoma, tub2> tub1, pT1a, N0, M0, fStage I A. There were many adenomas ranging from low-grade to high-grade in the duodenal mucosa. The patient remains well without any evidence of cancer recurrence more than 18 months after the last operation. When treating patients with duodenal adenoma complicated by FAP, regardless of age, strict follow-up is important.

Abstract
A 82-year-old man with anemia underwent upper endoscopy, and a hemorrhagic type 1 tumor was detected on the posterior wall of the duodenal bulb. This patient was diagnosed with neuroendocrine carcinoma(NEC)using biopsy. Distant metastasis was not found on imaging. He was referred to our department for the purpose of surgical therapy and underwent pancreaticoduodenectomy. Based on pathological findings, we diagnosed this patient as having NEC. No postoperative adjuvant chemotherapy was administered, but outpatient clinical follow-up was performed. The patient achieved 16 relapse-free months after surgery. Among the cases of NEC with a primary tumor arising from the digestive tract, cases of NEC of the duodenum that are not papillary carcinoma are rare. We report this case in along with a literature review.

Abstract
BACKGROUND Little information is available regarding microanatomy of lymphatic system in the ampulla of Vater, though it is of critical importance for an understanding of tumor progression via the lymphatics and determination of surgical strategy. The present study, therefore, aimed to demonstrate the distribution and microanatomical profiles on the lymphatic system in the ampulla. METHODS The fine distribution and structure of the lymphatic vessels were investigated in the ampulla and the stomach by immunohistochemistry for lymphatic- (D2-40) and blood vascular- (CD31) specific markers and scanning electron microscopy. The densities of lymphatic and blood vessels were also compared. RESULTS The duodenal papilla densely developed the lymphatics with distinct aspects of lymphatic capillaries, together with blood vessels. The density of lymphatic capillaries in the extramuscular layer in the ampulla was higher than those of both the other ampullary layers and the gastric extramuscular (subserosal) layer. CONCLUSIONS The ampulla of Vater showed widespread lymphatic capillaries throughout the entire wall. The specific vascular system is suited to produce lymph everywhere and drain without via such a large vessel as lymphatic collector. This suggests that tumor cells invade the lymphatics and metastasize more easily in the ampulla than in the other gastrointestinal regions.

Abstract
With the prolongation of the mean lifespan, the number of elderly individuals undergoing liver resection for colorectal cancer liver metastasis (CRLM) following chemotherapy has increased. However, the effect of age on the development of chemotherapy-associated liver injury (CALI) in CRLM remains unclear. The aim of the present study was to elucidate the effect of age on the development of CALI in CRLM. A total of 64 patients undergoing liver resection for CRLM following oxaliplatin-based chemotherapy (OBC) were investigated. The patients were divided into three groups (group A: <65 years, group B: 65-74 years and group C: >75 years) according to age at surgery, and the development rate of CALI was compared between the groups. The patients underwent pathological assessments to determine the degree of histopathological injury of the non-cancerous liver parenchyma. Group A included 37 cases, group B 17 cases and group C 10 cases. There were no significant differences among the groups regarding the number of OBC cycles and duration of OBC cessation. Sinusoidal injury was observed in 27.0, 29.4 and 30.0% of the cases in groups A, B and C, respectively; the differences were not statistically significant (P=0.479). Steatohepatitis was observed in 35.1, 35.3 and 40.0% of the cases in groups A, B and C, respectively; the differences were not statistically significant (P=0.958). There was no significant correlation between age and sinusoidal pathological score (r=-0.102, P=0.423) or non-alcoholic fatty liver disease activity score (r≤0.001, P=0.997). Therefore, the development of CALI following OBC treatment in CRLM was not found to differ by age.

Abstract
The aim of the present study was to investigate the early treatment outcomes of combined gemcitabine and nab-paclitaxel treatment for locally advanced unresectable pancreatic cancer (LURPC). The subjects comprised 7 patients with LURPC receiving the abovementioned combination therapy at the Hirosaki University Hospital (Hirosaki, Japan) between January and September, 2015. The clinicopathological factors, adverse events and response to treatment were investigated. To determine whether the cases were unresectable, the National Comprehensive Cancer Network guidelines, version 2. 201,) were applied. The patients underwent a median of 4 (range, 2-7) courses of treatment. The response to treatment was evaluated using the Response Evaluation Criteria In Solid Tumors. The subjects included 1 male and 6 female LURPC patients, with a median age of 71 years (range, 59-78 years). The tumor was located in the head and body of the pancreas in 6 and 1 patients, respectively. No patients achieved a complete response, 5 achieved a partial response, 2 had stable disease, and none exhibited progressive disease. The response rate was 71%. The mean tumor diameter decreased significantly from 35 mm (range, 24-60 mm) prior to treatment to 22 mm (range, 20-35 mm) following treatment. Two patients were downstaged. The mean carbohydrate antigen (CA) 19-9 values decreased significantly from 767 U/ml (range, 14-1,977 U/ml) prior to treatment to 35 U/ml (range, 14-123 U/ml) following treatment. Adverse events classified as grade ≥3 occurred in 4 patients (57%): 3 patients (43%) suffered from neutropenia and 1 patient (14%) developed bilateral cellulitis of the lower extremities. No patients experienced an increase in disease severity, and all were able to continue treatment following temporary withdrawal or dosage reduction. Therefore, combined treatment with gemcitabine and nab-paclitaxel had favorable tumor-reducing effects and was not associated with severe adverse events, suggesting that this is a useful therapeutic strategy for patients with LURPC.

There is ongoing discussion regarding the indications and timing of LT for patients with a preexisting extrahepatic malignancy. We herein report a pediatric case that underwent LDLT after therapy for YST. The patient, a 13-year-old female with biliary atresia, had undergone portoenterostomy at 2 months of age. She developed a left ovarian tumor with a high serum alpha-fetoprotein concentration at 10 years of age. She underwent left oophorectomy and was diagnosed with ovarian YST (Stage I). After surgery, hepatopulmonary syndrome progressed gradually. She was examined carefully and exhibited no findings to suggest the recurrence of YST. We decided to perform LDLT at 3 years and 6 months of age after the surgery for YST. The patient is currently alive and doing well without recurrence of YST at approximately 2 years after transplantation. There is no significant difference between the recurrence rate of preexisting extrahepatic malignancy and the incidence of de novo malignancy if specific cases are selected. The indications and period from surgery for preexisting extrahepatic malignancy to LT should thus be determined according to the type and stage of cancer.

Abstract
AIM The aim of this study was to examine the clinicopathological influence of tumor-infiltrating cluster of differentiation (CD) 163+ macrophages and CD8+ T-cells, and to clarify the prognostic effects of these cells in patients with invasive extrahepatic bile duct cancer (EHBC). MATERIALS AND METHODS The numbers of CD8+ T-cells in cancer cell nests and CD163+ macrophages in tumor stroma were evaluated using immunohistochemistry in 101 resected EHBC specimens. Correlations with clinicopathological variables and overall survival were analyzed. RESULTS Perihilar EHBC and perineural invasion were significantly associated with a low number of tumor-infiltrating CD8+ T-cells. Poorly- differentiated histology and nodal metastasis were significantly associated with a high number of tumor-infiltrating CD163+ macrophages. A combination of high number of CD8+ T-cells and low number of CD163+ macrophages was independently related to better overall survival in the whole patient cohort (hazard ratio=0.127, p<0.001) and in patients treated with adjuvant chemotherapy (hazard ratio=0.139, p=0.021). CONCLUSION Infiltrating CD163+ macrophages in tumor stroma and CD8+ T-cells in cancer cell nests have a prognostic impact in patients with EHBC following resection and also after adjuvant chemotherapy.

Abstract
The serum ferritin (SF) concentration is a widely available and objective laboratory parameter. SF is also widely recognized as an acute-phase reactant. The purpose of the present study was to identify the chronological changes in the recipient's SF concentration during liver transplantation (LT) and to clarify factors having an effect on the recipient's intraoperative SF level. In addition, the study retrospectively evaluated the usefulness of measuring SF during LT. Ninety-eight pediatric recipients were retrospectively analyzed. The data were analyzed and compared according to the SF level in the recipient. Patients were classified into 2 groups based on the intraoperative peak SF levels of ≤ 1000 ng/mL (low-SF group) or >1000 ng/mL (high-SF group). The SF value increased dramatically after reperfusion and fell to normal levels within the early postoperative period. The warm ischemia time (WIT) was significantly longer in the high-SF group (47.0 versus 58.5 minutes; P = 0.003). In addition, a significant positive correlation was observed between the peak SF value and WIT (r = 0.35; P < 0.001). There were significant positive correlations between the peak SF value and the donors' preoperative laboratory data, including transaminases, cholinesterase, hemoglobin, transferrin saturation, and SF, of which SF showed the strongest positive correlation (r = 0.74; P < 0.001). The multivariate analysis revealed that WIT and donor's SF level were a significant risk factor for high SF level in the recipient (P = 0.007 and 0.02, respectively). In conclusion, the SF measurement can suggest the degree of ischemia/reperfusion injury (IRI). A high SF level in the donor is associated with the risk of further acute reactions, such as IRI, in the recipient.

Abstract
Studies suggest that prophylactic intra-abdominal drains are unnecessary for cadaveric liver transplantation using whole liver grafts because there is no benefit from drainage. However, no studies have investigated on the necessity of prophylactic drains after LDLT using split-liver grafts or reduced-liver grafts, which may present a high risk of post-transplant intra-abdominal infections. This retrospective study investigated whether the ascitic data on POD 5 after LDLT can predict intra-abdominal infections and on the post-transplant management of prophylactic drains. Between March 2008 and March 2013, 90 LDLTs were performed. We assessed the number of ascitic cells, biochemical examinations, and cultivation tests at POD1 and POD5. The incidence rates of post-transplant intra-abdominal infections were 24.4%. The multivariate analysis showed that left lobe and S2 monosegment grafts were a significant risk factor for intra-abdominal infections (p = 0.006). The patients with intra-abdominal infections had significantly higher acsitic LDH levels and the positive rate of ascitic culture at POD5 in comparison with patients without infections (p < 0.001 and p = 0.014, respectively). LDLT using left lobe and S2 monosegment grafts yields a high risk for post-transplant intra-abdominal infections, and ascitic LDH and cultivation tests at POD5 via prophylactic drains can predict intra-abdominal infections.

Abstract
A 12-year-old female patient with biliary atresia underwent living donor liver transplantation (LDLT). Twelve months after the LDLT, she developed acute hepatitis (alanine aminotransferase 584 IU/L) and was diagnosed with disseminated varicella-zoster virus (VZV) infection with high level of serum VZV-DNA (1.5 × 105 copies/mL) and generalized vesicular rash. She had received the VZV vaccination when she was 5-years-old and had not been exposed to chicken pox before the LDLT, and her serum was positive for VZV immunoglobulin G at the time of the LDLT. Although she underwent treatment with intravenous acyclovir, intravenous immunoglobulin, and withdrawal of immunosuppressants, her symptoms worsened and were accompanied by disseminated intravascular coagulation, pneumonia, and encephalitis. These complications required treatment in the intensive care unit for 16 days. Five weeks later, her clinical findings improved, although her VZV-DNA levels remained high (8.5 × 103copies/mL). Oral acyclovir was added for 2 weeks, and she was eventually discharged from our hospital on day 86 after admission; she has not experienced a recurrence. In conclusion, although disseminated VZV infection with multiple organ failure after pediatric LDLT is a life-threatening disease, it can be cured via an early diagnosis and intensive treatment.

Abstract
Previous studies have demonstrated the safety of ABO-incompatible pediatric LDLT using preoperative plasmapheresis and rituximab; however, no reports have described the timing and dosage of rituximab administration for pediatric LDLT. This study aimed to describe a safe and effective dosage and timing of rituximab for patients undergoing pediatric ABO-incompatible LDLT based on the experience of our single center. A total of 192 LDLTs in 187 patients were examined. These cases included 29 ABO-incompatible LDLTs in 28 patients. Rituximab was used beginning in January 2004 in recipients older than two yr of age (first period: 375 mg/m(2) in two cases; second period: 50 mg/m(2) in two cases; and 200 mg/m(2) in eight cases). Two patients who received 375 mg/m(2) rituximab died of Pneumocystis carinii pneumonia and hemophagocytic syndrome. One patient who received 50 mg/m(2) rituximab required retransplantation as a consequence of antibody-mediated complications. All eight patients administered 200 mg/m(2) survived, and the mean CD20(+) lymphocyte count was 0.1% at the time of LDLT. In the preoperative management of patients undergoing pediatric ABO-incompatible LDLT, the administration of 200 mg/m(2) rituximab three wk prior to LDLT was safe and effective.

Abstract
In the field of pediatric living donor liver transplantation (LDLT), physicians sometimes must reduce the volume of left lateral segment (LLS) grafts to prevent large-for-size syndrome. There are 2 established methods for decreasing the size of an LLS graft: the use of a segment 2 (S2) monosegment graft and the use of a reduced LLS graft. However, no procedure for selecting the proper graft type has been established. In this study, we conducted a retrospective investigation of LDLT and examined the strategy of graft selection for patients weighing ≤6 kg. LDLT was conducted 225 times between May 2001 and December 2012, and 15 of the procedures were performed in patients weighing ≤6 kg. We selected S2 monosegment grafts and reduced LLS grafts if the preoperative computed tomography (CT)-volumetry value of the LLS graft was >5% and 4% to 5% of the graft/recipient weight ratio, respectively. We used LLS grafts in 7 recipients, S2 monosegment grafts in 4 recipients, reduced S2 monosegment grafts in 3 recipients, and a reduced LLS graft in 1 recipient. The reduction rate of S2 monosegment grafts for use as LLS grafts was 48.3%. The overall recipient and graft survival rates were both 93.3%, and 1 patient died of a brain hemorrhage. Major surgical complications included hepatic artery thrombosis in 2 recipients, bilioenteric anastomotic strictures in 2 recipients, and portal vein thrombosis in 1 recipient. In conclusion, our graft selection strategy based on preoperative CT-volumetry is highly useful in patients weighing ≤6 kg. S2 monosegment grafts are effective and safe in very small infants particularly neonates.

Abstract
BACKGROUND Blood transfusion is linked to a negative outcome for malignant tumors. The aim of this study was to evaluate aggressive surgical resection for hilar cholangiocarcinoma (HCCA) and assess the impact of perioperative blood transfusion on long-term survival. METHODS Sixty-six consecutive major hepatectomies with en bloc resection of the caudate lobe and extrahepatic bile duct for HCCA were performed using macroscopically curative resection at our institute from 2002 to 2012. Clinicopathologic factors for recurrence and survival were retrospectively assessed. RESULTS Overall survival rates at 1, 3, and 5 years were 86.7, 47.3, and 35.7 %, respectively. In univariate analysis, perioperative blood transfusion and a histological positive margin were two of several variables found to be significant prognostic factors for recurrence or survival (P<0.05). In multivariate analysis, only perioperative blood transfusion was independently associated with recurrence (hazard ratio (HR)=2.839 (95 % confidence interval (CI), 1.370-5.884), P=0.005), while perioperative blood transfusion (HR=3.383 (95 % CI, 1.499-7.637), P=0.003) and R1 resection (HR=3.125 (95 % CI, 1.025-9.530), P=0.045) were independent risk factors for poor survival. CONCLUSIONS Perioperative blood transfusion is a strong predictor of poor survival after radical hepatectomy for HCCA. We suggest that circumvention of perioperative blood transfusion can play an important role in long-term survival for patients with HCCA.

Abstract
A man in his 60s was diagnosed with gastric cancer and underwent distal gastrectomy and D2 lymph node dissection. The histological diagnosis was adenocarcinoma (T3, N1, StageIIB). He was treated with S-1 as adjuvant chemotherapy for 1 year. One year and 2 months after gastrectomy, a computed tomography (CT) scan revealed liver metastasis (S8, 38 mm). The patient was diagnosed with liver metastasis(refractory to S-1), and administered combination chemotherapy with irinotecan and cisplatin. After 4 courses of treatment, a CT scan detected a progressive liver tumor (55 mm). Combination chemotherapy with docetaxel and S-1 was selected as second-line chemotherapy. After 6 courses of treatment, the tumor size reduced to 40 mm in diameter, and no other metastasis was detected. Nine months after the diagnosis of liver metastasis, partial resection of the liver (S8) was performed. A pathological diagnosis of metastatic adenocarcinoma was determined, and the pathological therapeutic effect was rated as Grade 1b. Combination chemotherapy with docetaxel and S-1 was found to be effective, and was thus administrated after the operation. There have been no signs of recurrence for 6 months after the operation. Surgery with perioperative chemotherapy can be an effective treatment for liver metastasis from gastric cancer.

Abstract
Perforation, bleeding, and ileus are known complications of small intestinal lymphoma and can occur either at diagnosis or during the course of treatment. Surgery is an important component in the management of these gastrointestinal complications. However, there is no consensus regarding the indications for and timing of surgery in small intestinal lymphoma. We herein present our experience with a case of small intestinal lymphoma with ileus that required surgery during chemotherapy. A 69-year-old man developed abdominal pain. Computed tomography revealed lower right jaw lymphadenopathy, small intestinal wall thickening, and mesenteric lymphadenopathy. Malignant lymphoma (diffuse large B-cell type) was diagnosed on the basis of a lower jaw lymph node biopsy. The patient was initially administered chemotherapy. After the third cycle of chemotherapy, the patient developed small intestinal obstruction detected upon abdominal computed tomography. Because a stricture persisted despite medical treatment, we performed partial resection of the small intestine. The postoperative course was good, and the patient rapidly resumed chemotherapy. Currently, 6 months after the surgery, the patient is alive without any progression of the lymphoma. A multidisciplinary treatment strategy, including surgery, is desirable to achieve a safe but radical cure for small intestinal lymphoma.

A man in his seventies presented with a stomach abnormality that was revealed upon physical examination.Following workup, he was diagnosed with gastric diffuse large B-cell lymphoma (DLBCL)StageII1 (Lugano staging system for gastrointestinal lymphoma) with low risk as defined by the International Prognostic Index criteria.The entire stomach showed an intense, abnormal FDG uptake by FDG-PET evaluation.He was treated with rituximab plus CHOP (R-CHOP).The patient's body weight decreased by 12 kg during the treatment period.Post -treatment evaluation by gastroscopy and FDG-PET following 5 courses of R-CHOP therapy revealed a residual lesion in the stomach.Total gastrectomy was performed for R-CHOP refractory gastric DLBCL.The pathological diagnosis was DLBCL, and the pathological therapeutic effect was Grade 1a.Lymphoma cells were detected at the duodenal margin of the resected specimen, and an FDG-PET scan showed abnormal FDG uptake in the duodenal stump necessitating salvage chemotherapy (DeVIC therapy)and radiotherapy.The patient's body weight increased by 5 kg after gastrectomy and there were no signs of relapse for 14 months after the operation.Salvage therapy including gastrectomy may be effective for chemotherapy-resistant gastric DLBCL.

Abstract
BACKGROUND The indocyanine green (ICG) clearance test is reported to be useful for the preoperative evaluation of hepatic functional reserve. However, the ICG clearance test has not been sufficiently investigated in patients with colorectal liver metastasis after chemotherapy. The aim of the present study was to evaluate whether the ICG clearance test is a useful parameter for the preoperative detection of chemotherapy-associated liver injury. METHODS Ninety-four patients undergoing liver resection for colorectal liver metastasis after chemotherapy were studied. The medical records for each case were retrospectively reviewed. They underwent pathological assessment to clarify the degree of histopathological liver injury of the nontumoral liver parenchyma. In addition, the correlation between the pathological score and the ICG retention rate at 15 min (ICG-R15) was analyzed. RESULTS Sinusoidal injury was observed in the 31 of 94 patients. Steatohepatitis was observed in the 40 of 94 patients. There was no strong correlation between the preoperative ICG-R15 value and the sinusoidal pathological score (r = 0.117, P = 0.261). There was no strong correlation between the ICG-R15 and the nonalcoholic fatty liver disease activity score (r = 0.215, P = 0.037). CONCLUSIONS It was difficult to predict the degree of chemotherapy-associated liver injury by the preoperative ICG-R15 value. It is necessary to estimate the hepatic functional reserve based on a combination of several clinical indicators without relying on the ICG test, in order to perform a safe radical liver resection.

Abstract
BACKGROUND/AIMS β-D glucan in the portal vein blood is processed by the hepatic reticuloendothelial system, and therefore, it is possible that the β-D glucan kinetics of the peripheral vein blood may be useful as a biological index. In this study, the β-D glucan levels in the peripheral and portal vein blood during liver transplantation were measured in order to study the clinical significance of the molecule. METHODOLOGY The subjects comprised 20 patients who underwent living donor liver transplantation. In the perioperative period, the β-D glucan levels were measured before liver transplantation, during surgical procedure, then on postoperative days 5, 14 and 21. RESULTS The portal vein blood showed a significantly higher level of β-D glucan than the peripheral blood (p<0.001). A significant difference of β-D glucan levels was observed between the pre-liver transplantation and postoperative days 5 (p=0.048). There was a significant positive correlation between the preoperative β-D glucan level and the period of postoperative hospitalization (p<0.001). The patients with fungal infections (35.0%) had a significantly longer period of hospitalization (p=0.019). CONCLUSIONS The β-D glucan kinetics accurately reflects the liver function and fungal infections. The β-D glucan level before liver transplantation can be used to

Abstract
AIM: To assessed the clinical significance of protocol liver biopsy (PLB) in pediatric liver transplantation (LT).
METHODS: Between July 2008 and August 2012, 89 and 55 PLBs were performed in pediatric patients at two and five years after LT, respectively. We assessed the histopathological findings using the Metavir scoring system, including activity (A) and fibrosis (F), and we identified factors associated with scores of ≥ A1 and ≥ F1. Our results clarified the timing and effectiveness of PLB.
RESULTS: The incidences of scores of ≥ A1 and ≥ F1 were 24.7% and 24.7%, respectively, at two years after LT and 42.3% and 34.5%, respectively, at five years. Independent risk factors in a multivariate analysis of a score of ≥ A1 at two years included ≥ 2 h of cold ischemic time, no acute cellular rejection and an alanine amino transaminase (ALT) level of ≥ 20 IU/L (P = 0.028, P = 0.033 and P = 0.012, respectively); however, no risk factors were identified for a score of ≥ F1. Furthermore, no independent risk factors associated with scores of ≥ A1 and ≥ F1 at five years were identified using multivariate analysis. A ROC curve analysis of ALT at two years for a score of ≥ A1 demonstrated the recommended cutoff value for diagnosing ≥ A1 histology to be 20 IU/L. The incidence of scores of ≥ A2 or ≥ F2 at two years after LT was 3.4% (three cases), and all patients had an absolute score of ≥ A2. In contrast to that observed for PLBs at five years after LT, the incidence of scores of ≥ A2 or ≥ F2 was 20.0% (11 cases), and all patients had an absolute score of ≥ F2. In all cases, the dose of immunosuppressants was increased after the PLB, and all ten patients who underwent a follow-up liver biopsy improved to scores of ≤ A1 or F1.
CONCLUSION: PLB at two years after LT is an unnecessary examination, because the serum ALT level reflects portal inflammation. In addition, immunosuppressive therapy should be modulated to maintain the ALT concentration at a level less than 20 IU/L. PLB at five years is an excellent examination for the detection of early reversible graft fibrosis because no serum markers reflect this finding.

Abstract
Iron is an essential nutrient for living cells; however, an excessive accumulation of iron leads to organ damage and directly affects systemic immunity. Iron overload is clinically classified as hereditary or secondary. Most of secondary iron overload is caused by frequent blood transfusions because there is no active mechanism to excrete iron from the body. As recommended in various guidelines, chelation therapy is effective for reducing iron burden and improving organ function. There have been few reports on iron overload through blood transfusion during the perioperative period of liver transplantation. This report presents a case of iron overload due to repeated transfusions after pediatric liver transplantation managed by chelation therapy. The patient, an 11-month-old female with biliary atresia, underwent living donor liver transplantation. She revealed refractory anemia and required frequent blood transfusion. Both serum ferritin and transferrin saturation tended to increase after repeated transfusions, leading to secondary iron overload. Iron chelation therapy was started to prevent progression to organ failure and infection due to iron overload, and yielded a favorable outcome. It is crucial to consider the possibility of secondary iron overload and to achieve early detection and treatment to avoid progression to irreversible organ damage.
