Abstract
INTRODUCTION This study aimed to evaluate the short- and long-term outcomes of single-incision laparoscopic colectomy (SILC) for right-sided colon cancer (CC) using a craniocaudal approach. PATIENTS AND METHODS The data of patients who underwent SILC for right-sided CC at our hospital between January 2013 and December 2022 were retrospectively collected. Surgery was performed using a craniocaudal approach. Short- and long-term operative outcomes were analysed. RESULTS In total, 269 patients (127 men, 142 women; median age 74 years) underwent SILC for right-sided CC. The cases included ileocaecal resection (n = 138) and right hemicolectomy (n = 131). The median operative time was 154 min, and the median operative blood loss was 0 ml. Twenty-seven cases (10.0%) required an additional laparoscopic trocar, and 9 (3.3%) were converted to open surgery. The Clavien-Dindo classification Grade III post-operative complications were detected in 7 (2.6%) cases. SILC was performed by 25 surgeons, including inexperienced surgeons, with a median age of 34 years. The 5-year cancer-specific survival (CSS) was 96.1% (95% confidence interval [CI] 91.3%-98.2%), and CSS per pathological disease stage was 100% for Stages 0-I and II and 86.2% (95% CI 71.3%-93.7%) for Stage III. The 5-year recurrence-free survival (RFS) was 90.6% (95% CI 85.7%-93.9%), and RFS per pathological disease stage was 100% for Stage 0-I, 91.7% (95% CI 80.5%-96.6%) for Stage II and 76.1% (95% CI 63.0%-85.1%) for Stage III. CONCLUSIONS SILC for right-sided CC can be safely performed with a craniocaudal approach, with reasonable short- and long-term outcomes.

Abstract
A 64-year-old female received modified FOLFOX6 therapy with continuous administration of a high concentration of 5-fluorouracil (5-FU) for recurrence of peritoneal dissemination after total gastrectomy. Twenty-nine hours after the administration, there was the sudden onset of altered consciousness and hepatic dysfunction accompanied by hyperammonemia. The consciousness and hepatic function improved the following day after treatment with branched-chain amino acid formulation, lactulose, fresh frozen plasma, and continuous hemodiafiltration. Thus, the diagnosis was 5-FU-induced hyperammonemia. Improvement of dehydration and renal dysfunction would be important for avoiding the risk of developing the side effects. Because recurrent gastric cancer is often a progressive condition, post-treatment might be promptly transferred to the other posterior regimen without 5-FU as required.

Abstract
BACKGROUND Prevention of bile duct injury and vasculo-biliary injury while performing laparoscopic cholecystectomy (LC) is an unsolved problem. Clarifying the surgical difficulty using intraoperative findings can greatly contribute to the pursuit of best practices for acute cholecystitis. In this study, multiple evaluators assessed surgical difficulty items in unedited videos and then constructed a proposed surgical difficulty grading. METHODS We previously assembled a library of typical video clips of the intraoperative findings for all LC surgical difficulty items in acute cholecystitis. Fifty-one experts on LC assessed unedited surgical videos. Inter-rater agreement was assessed by Fleiss's κ and Gwet's agreement coefficient (AC). RESULTS Except for one item ("edematous change"), κ or AC exceeded 0.5, so the typical videos were judged to be applicable. The conceivable surgical difficulty gradings were analyzed. According to the assessment of difficulty factors, we created a surgical difficulty grading system (agreement probability = 0.923, κ = 0.712, 90% CI: 0.587-0.837; AC2 = 0.870, 90% CI: 0.768-0.972). CONCLUSION The previously published video clip library and our novel surgical difficulty grading system should serve as a universal objective tool to assess surgical difficulty in LC.

Abstract
BACKGROUND AND PURPOSE Selective voluntary motor control is an important factor influencing gross motor function, interjoint coordination, and the outcome of hamstring-lengthening surgery in spastic cerebral palsy. Using DTI, we investigated whether selective voluntary motor control would show strong correlations with WM motor tract microstructure and whether selective voluntary motor control is more sensitive to global WM impairment than gross motor function. MATERIALS AND METHODS Children with spastic bilateral cerebral palsy born preterm and typically developing children were recruited. The Selective Control Assessment of the Lower Extremity (SCALE) and Gross Motor Function Measure (GMFM) were assessed in participants with cerebral palsy. Participants underwent brain MR imaging to collect DWI data. Tract-Based Spatial Statistics was used to analyze the WM for between-group differences and correlations with SCALE and GMFM. ROI analyses compared motor regions. RESULTS Twelve children with cerebral palsy (mean age, 11.5 years) and 12 typically developing children (mean age, 10.3 years) participated. Altered DTI outcomes were found throughout the whole brain for the cerebral palsy group. SCALE, developed to evaluate selective voluntary motor control in cerebral palsy, showed significant positive correlations with fractional anisotropy in more WM voxels throughout the whole brain and for motor regions, including the corticospinal tract and corpus callosum, compared with GMFM. A significant negative correlation between radial diffusivity and SCALE, but not GMFM, was found within the corpus callosum. CONCLUSIONS SCALE was a more sensitive clinical correlate of motor and whole-brain WM tract impairment in children with spastic bilateral cerebral palsy, suggesting greater anisotropy and myelination in these regions for those with higher selective voluntary motor control.

Abstract
Background Pancreatoduodenectomy with resection of the portal vein or superior mesenteric vein confluence has been safely performed in patients with pancreatic head cancer associated with infiltration of the portal vein or superior mesenteric vein. In recent years, left-sided portal hypertension, a late postoperative complication, has received focus owing to increased long-term survival with advances in chemotherapy. Left-sided hypertension may sometimes cause fatal gastrointestinal bleeding because of the rupture of gastrointestinal varices. Here, we present a case of colonic varices caused by left-sided portal hypertension after pancreatoduodenectomy with portal vein resection. Case presentation A 69-year-old man diagnosed with pancreatic head cancer was referred to our department for surgery after undergoing chemotherapy with nine courses of gemcitabine and nab-paclitaxel. Computed tomography showed a mass 25 mm in diameter and in contact with the portal vein. He had undergone subtotal stomach-preserving pancreatoduodenectomy with portal vein resection. Four centimeters of the portal vein had been resected, and end-to-end anastomosis was performed without splenic vein reconstruction. We had to completely resect the right colic vein, accessary right colic vein, and middle colic vein due to tumor invasion. The pathological diagnosis was ypT3, ypN1a, ypM0, and ypStageIIB, and he was administered TS-1 as postoperative adjuvant chemotherapy. Seven months after therapeutic radical surgery, he presented with melena with progressive anemia. Computed tomography revealed transverse colonic varices. He was offered interventional radiology. Trans-splenic arterial splenic venography showed that transverse colonic varices had developed as collateral circulation of the splenic vein and inferior mesenteric vein system. An embolic substance was injected into the transverse colonic varices, which halted the progression of the anemia caused by melena. Fifteen months after therapeutic radical surgery, local recurrence of the tumor occurred; he died 28 months after the surgery. Conclusions When subtotal stomach-preserving pancreatoduodenectomy with portal vein resection is performed without splenic vein reconstruction, colonic varices may result from left-sided portal hypertension. Interventional radiology is an effective treatment for gastrointestinal bleeding due to colonic varices, but it is important to be observant for colonic necrosis and new varices.

Abstract
Objective: IgG4-related sclerosing cholecystitis is generally associated with IgG4-related sclerosing cholangitis and presents with diffuse, circumferential thickening of the gallbladder wall. We report a rare case of localized IgG4-related sclerosing cholecystitis without IgG4-related sclerosing cholangitis, which was difficult to differentiate from gallbladder cancer preoperatively. Patient: A 56-year-old man with suspected IgG4-related disease or gallbladder cancer was admitted to our ward. The serum IgG4 level was elevated at 721 mg/dL. Computed tomography (CT) demonstrated focal wall thickening of the gallbladder fundus. Drip infusion cholecystocholangiography with CT revealed no dilation, stenosis, or border irregularity of the bile duct. Results: For diagnostic and treatment purposes, cholecystectomy with wedge resection of the gallbladder bed was performed. The pathological diagnosis was IgG4-related sclerosing cholecystitis. Conclusion: It is difficult to differentiate IgG4-related sclerosing cholecystitis from gallbladder cancer in cases involving localized thickening of the gallbladder wall. In similar cases, surgical resection with cancer in mind might be performed based on present clinical knowledge.

Abstract
The radiative cooling of highly excited carbon cluster cations of sizes N = 8, 10, 13-16 has been studied in an electrostatic storage ring. The cooling rate constants vary with cluster size from a maximum at N = 8 of 2.6 × 104 s-1 and a minimum at N = 13 of 4.4 × 103 s-1. The high rates indicate that photon emission takes place from electronically excited ions, providing a strong stabilizing cooling of the molecules.

Abstract
PURPOSE Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique for temporary stabilization of patients with non-compressible torso hemorrhage. This technique has been increasingly used worldwide during the past decade. Despite the good outcomes of translational studies, clinical studies are divided. The aim of this multicenter-international study was to capture REBOA-specific data and outcomes. METHODS REBOA practicing centers were invited to join this online register, which was established in September 2014. REBOA cases were reported, both retrospective and prospective. Demographics, injury patterns, hemodynamic variables, REBOA-specific data, complications and 30-days mortality were reported. RESULTS Ninety-six cases from 6 different countries were reported between 2011 and 2016. Mean age was 52 ± 22 years and 88% of the cases were blunt trauma with a median injury severity score (ISS) of 41 (IQR 29-50). In the majority of the cases, Zone I REBOA was used. Median systolic blood pressure before balloon inflation was 60 mmHg (IQR 40-80), which increased to 100 mmHg (IQR 80-128) after inflation. Continuous occlusion was applied in 52% of the patients, and 48% received non-continuous occlusion. Occlusion time longer than 60 min was reported as 38 and 14% in the non-continuous and continuous groups, respectively. Complications, such as extremity compartment syndrome (n = 3), were only noted in the continuous occlusion group. The 30-day mortality for non-continuous REBOA was 48%, and 64% for continuous occlusion. CONCLUSIONS This observational multicenter study presents results regarding continuous and non-continuous REBOA with favorable outcomes. However, further prospective studies are needed to be able to draw conclusions on morbidity and mortality.

Abstract
Objective Guided self-help treatments based on cognitive behavioral therapy (CBT-GSH) are regarded as a first-line effective treatment for bulimia nervosa (BN). With limited application for CBT-GSH in Japanese clinical settings, we conducted a single arm pilot study in order to confirm the acceptability and availability of CBT-GSH in Japan. Results 25 women with BN received 16–20 sessions of face-to-face CBT-GSH. Primary outcomes were the completion rate of intervention and abstinence rates from objective bingeing and purging as assessed by the Eating Disorder Examination. Secondary outcomes were other self-report measurements of the frequency of bingeing and purging, and characteristic psychopathologies of eating disorders. Assessments were conducted before CBT as baseline as well as after CBT. 92% (23/25) of the participants completed the CBT sessions. After CBT-GSH, 40% (10/25) of the participants (intention-to-treat) achieved symptom abstinence. The mean binge and purge episodes during the previous 28 days improved from 21.88 to 10.96 (50% reduction) and from 22.44 to 10.88 (52% reduction), each (before CBT-GSH to after CBT-GSH), and the within-group effect sizes were medium (Cohen’s d = 0.67, 0.65, each). Our study provided a preliminary evidence about the feasibility of CBT-GSH in Japanese clinical settings for the future. Trial registration This study was registered retrospectively in the national UMIN Clinical Trials Registry on July 10, 2013 (registration ID: UMIN000011120)

Abstract
We herein report the case of a 78-year-old woman with an intraductal tumor with scant mucin production in a moderately dilated main pancreatic duct that resembled an intraductal tubulopapillary neoplasm (ITPN) on imaging. An endoscopic transpapillary forceps biopsy enabled an accurate preoperative diagnosis of the tumor as an oncocytic type intraductal papillary mucinous neoplasm (IPMN) of the pancreas microscopically showing papillary growth consisting of oncocytic cells with a typical mucin expression profile, although with few intraepithelial lumina containing mucin. This is the first case of an oncocytic type IPMN mimicking an ITPN that was able to be diagnosed preoperatively.

Abstract
PURPOSE The aim of this study is to evaluate the early survival and organ damage following 30 and 60 min of thoracic resuscitative endovascular balloon occlusion of the aorta (REBOA) in an ovine model of severe hemorrhagic shock. METHODS Eighteen sheep were induced into shock by undergoing a 35 % controlled exsanguination over 30 min. Animals were randomized into three groups: 60-min REBOA 30 min after the bleeding (60-REBOA), 30-min REBOA 60 min after the bleeding (30-REBOA) and no-REBOA control (n-REBOA). Resuscitation with crystalloids and whole blood was initiated 20 and 80 min after the induction of shock. Animals were observed for 24 h with serial potassium and lactate measurements. Autopsy was performed to evaluate organ damage. RESULTS Two animals of the n-REBOA group died within 90 min of shock induction; no hemorrhagic deaths were observed in the REBOA groups. Twenty-four-hour survival for the 60-, 30-, and n-REBOA groups was 0/6, 5/6, and 4/6 (P = 0.002). In 60-REBOA, potassium and lactate were increased at 270-min time point: from 4.3 to 5.1 mEq/l and from 3.7 to 5.1 mmol/L, respectively. Both these values were significantly higher than in the n-REBOA group (P = 0.029 for potassium and P = 0.039 for lactate). Autopsy revealed acute tubular necrosis in all died REBOA group animals. CONCLUSIONS In this ovine model of severe hemorrhagic shock, REBOA can be used to prevent early death from hemorrhage; however, 60 min of occlusion results in significant metabolic derangement and organ damage that offsets this gain.

Abstract
This article proposes an innovative concept of interventional radiology for hemodynamically unstable trauma patients. Damage control interventional radiology (DCIR) is an aggressive and time-conscious algorithm that prioritizes saving life of the hemorrhaging patient in extremis which conventional emergency interventional radiology (CEIR) cannot efficiently do. Briefly, DCIR aims to save life while CEIR aims to control bleeding with a constant concern to time-awareness. This article also presents the concept of "Prompt and Rapid Endovascular Strategies in Traumatic Occasions" (PRESTO) that entirely oversees and manages trauma patients from arrival to the trauma bay until initial completion of hemostasis with endovascular techniques. PRESTO's "Start soon and finish sooner" relies on the earlier activation of interventional radiology team but also emphasizes on a rapid completion of hemostasis in which DCIR has been specifically tailored. Both DCIR and PRESTO expand the role of IR and represent a paradigm shift in the realm of trauma care.

Abstract
This report describes a case of a patient with a large solid gallbladder adenocarcinoma that was completely resected through aggressive surgery. The patient was a 57-year-old woman who had been diagnosed with advanced gallbladder cancer, had no indications for surgical resection and was scheduled to undergo systemic chemotherapy. She presented to our hospital for a second opinion. At the time of assessment, her tumor was large but was well-localized and had not invaded into the surrounding tissues, indicating that surgical resection was a reasonable option. Subsequently, the tumor was completely extracted via right hepatectomy with en bloc resection of the caudate lobe and extrahepatic bile duct. Histopathologically, the tumor was a solid adenocarcinoma. Although there are relatively few reports in the literature regarding solid gallbladder adenocarcinoma, well-localized growth appears to be a characteristic feature. On the basis of a tumor’s progression behavior, aggressive surgical treatment might be indicated even when the tumor has grown to a considerable size.

Abstract
We provide the experimental evidence that the single electron capture process in slow collisions between O^{3+} ions and neon dimer targets leads to an unexpected production of low-energy electrons. This production results from the interatomic Coulombic decay process, subsequent to inner-shell single electron capture from one site of the neon dimer. Although pure one-electron capture from the inner shell is expected to be negligible in the low collision energy regime investigated here, the electron production due to this process overtakes by 1 order of magnitude the emission of Auger electrons by the scattered projectiles after double-electron capture. This feature is specific to low charge states of the projectile: similar studies with Xe^{20+} and Ar^{9+} projectiles show no evidence of inner-shell single-electron capture. The dependence of the process on the projectile charge state is interpreted using simple calculations based on the classical over the barrier model.

Abstract
Background Post-operative anastomotic insufficiency following major hepato-biliary surgery has significant impacts on the post-operative course. Recent reports have revealed that platelets play an important role in liver regeneration and wound healing. From these experimental and clinical results on platelet function, we hypothesized that post-operative platelet depletion (to <10 × 104/μL) would be associated with delayed liver regeneration as well as anastomotic insufficiency of intrahepatic cholangiojejunostomy. However, little information is available regarding correlations between platelet count and these complications. The purposes of the present study were, firstly, to evaluate the incidence of anastomotic insufficiency following intrahepatic cholangiojejunostomy and, secondly, to evaluate whether platelet depletion represents a risk factor for anastomotic insufficiency in intrahepatic cholangiojejunostomy. Methods Participants in this study comprised 220 consecutive patients who underwent intrahepatic cholangiojejunostomy following hepato-biliary resection for biliary malignancies between September 1998 and December 2010. Anastomotic insufficiency was confirmed by cholangiographic demonstration of leakage from the anastomosis using contrast medium introduced via a biliary drainage tube or prophylactic drain placed during surgery. Results Anastomotic insufficiency of the intrahepatic cholangiojejunostomy occurred in 13 of 220 patients (6%). Thirteen of the 220 patients, including one with anastomotic insufficiency, died during the study. Uni- and multivariate analyses both revealed that platelet depletion on post-operative day 1 (<10 × 104/μL) correlated with anastomotic insufficiency. Conclusion Post-operative platelet depletion was closely associated with anastomotic insufficiency following intrahepatic cholangiojejunostomy. This correlation has been established, but the underlying mechanisms have not.

Abstract
Electron capture processes for low energy Ar(9+) ions colliding with Ar(2) dimer targets are investigated, focusing attention on charge sharing between the two Ar atoms as a function of the molecular orientation and the impact parameter. A preference for charge-asymmetric dissociation channels is observed, with a strong correlation between the projectile scattering angle and the molecular ion orientation. The measurements here provide clear evidence that projectiles distinguish each atom in the target and that electron capture from near-site atoms is favored. Monte Carlo calculations based on the classical over-the-barrier model, with dimer targets represented as two independent atoms, are compared to the data. They give new insight into the dynamics of the collision by providing, for the different electron capture channels, the two-dimensional probability maps p(b), where b is the impact parameter vector in the molecular frame.

Abstract
We report conclusive evidence of an efficient cooling mechanism via the electronic radiative transitions of hot small molecular anions isolated in vacuum. We stored C6(-) and C6H(-) in an ion storage ring and observed laser-induced electron detachment with delays up to several milliseconds. The terminal hydrogen atom caused a drastic change in the decay profiles. The decay of photoexcited C6H(-) is slow and nonexponential, which can be explained by depletion cooling, whereas that for C6(-) occurs extremely fast, on a time scale below 0.1 ms and can only be explained by electronic radiative cooling via low-lying electronic excited states.

Abstract
Due to advances in endoscopic equipment and techniques, preoperative endoscopic biliary drainage (EBD) has been developed to serve as an alternative to percutaneous transhepatic biliary drainage (PTBD). This study sought to clarify the benefit of EBD in comparison to PTBD in patients who underwent radical resections of hilar cholangiocarcinoma. One hundred and forty-one patients underwent radical surgery for hilar cholangiocarcinoma between 2000 and 2008 were retrospectively divided into two groups based on the type of preoperative biliary drainage, PTBD (n = 67) or EBD (n = 74). We investigated if the different biliary drainage methods affected postoperative survival and mode of recurrence after median observation period of 82 months. The survival rate for patients who underwent EBD was significantly higher than those who had PTBD (P = 0.004). Multivariate analysis revealed that PTBD was one of the independent factors predictive of poor survival (hazard ratio: 2.075, P = 0.003). Patients with PTBD more frequently developed peritoneal seeding in comparison to those who underwent EBD (P = 0.0003). PTBD was the only independent factor predictive of peritoneal seeding. In conclusion, EBD might confer an improved prognosis over PTBD due to prevention of peritoneal seeding, and is recommended as the initial procedure for preoperative biliary drainage in patients with hilar cholangiocarcinoma.

Abstract
OBJECTIVES To assess the safety and feasibility and discuss the oncological impact of a portal vein resection using the no-touch technique with a hepatectomy for locally advanced hilar cholangiocarcinoma. PATIENTS AND METHODS From 2005 to March 2009, 49 patients with hilar cholangiocarcinoma underwent a major right-sided hepatectomy with curative intent. Portal vein resection was performed using the no-touch technique in 36 patients (PVR group) but the portal vein was not resected in the other 13 patients (NR group). Peri-operative data and histological findings were compared between the two groups. Moreover, tumour recurrence and survival rates after surgery were calculated and compared for each group. RESULTS Although the tumours of the patients in the PVR group were more locally advanced, the residual tumour status and tumour recurrence rate were similar and there was no significant difference in long-term survival between the two groups: 5-year survival rates in the PVR and NR groups were 59% and 51%, respectively (P = 0.353). In-hospital mortality was encountered in 2 of the 49 patients. CONCLUSION A portal vein resection using the no-touch technique with a right-sided hepatectomy had a positive impact on survival and is feasible in terms of long-term outcomes with acceptable mortality.

Abstract
BACKGROUND/AIMS There have been few papers on how to treat hepatobiliary malignancies after ERCP-related pancreatitis focusing on the timing of the operation and postoperative complications. The aim of this study was to clarify the relationship among the time after the pancreatitis, the complexity of the operation, and the characteristic postoperative complications. METHODOLOGY The clinicopathological characteristics of five patients with hepatobiliary malignancies who had a prior history of ERCP-related pancreatitis were analyzed. RESULTS The five patients included two with extrahepatic bile duct carcinomas, two with ampulla of Vater carcinomas, and one with intrahepatic hilar cholangiocarcinoma. The median time to the operation from pancreatitis was 31 (16-116) days. The median operation time and blood loss were 661 (576-924) min and 3695 (2730-7240) mL, respectively. Various postoperative complications were seen in all cases including acute respiratory distress syndrome and infection of peripancreatic necrosis. The postoperative mortality rate was 0%, with a morbidity rate of 100%. R0 operations were performed in all five cases. CONCLUSIONS Surgery for hepatobiliary malignancies after ERCP-related pancreatitis appears to have a high morbidity rate. The surgery must strike a balance between curability of the malignancy and safety with respect to the frequent postoperative complications.

Abstract
Pancreatic cancer is an aggressive cancer with poor prognosis. Little is known about the immune response in the tumor microenvironment after chemotherapy for initially unresectable tumor. The purpose of this study was to investigate the immunological effects of chemoradiation therapy in the tumor microenvironment of pancreatic adenocarcinoma. Seventeen patients with pancreatic adenocarcinoma with and without preoperative chemoradiation therapy were retrospectively analyzed using immunohistochemical methods for HLA class I heavy chain, CD4(+), CD8(+), CD45RO(+) and Foxp3(+) T cell infiltrations. Seven of the 17 study patients received preoperative chemoradiation therapy. There were no statistically significant differences in the number of CD4(+) and CD8(+) T cell infiltrations in the tumor microenvironment. However, the number of Foxp3(+) T cell infiltrations was significantly lower in the neoadjuvant chemoradiation therapy group. The HLA class I expression status was the same between the two groups. In conclusion, preoperative chemoradiation therapy in pancreatic adenocarcinoma is useful for reducing regulatory T cell levels in combination with its direct cytotoxic effects.

Abstract
BACKGROUND/AIMS Pancreatic neuroendocrine tumors (PNETs) are rare neoplasms. Little is known about the mode of recurrence and long term prognosis after resection. We aimed to evaluate the surgical indication, especially for the patients with concomitant multiple liver metastases or extreme local invasions. METHODOLOGY The overall survival (OS) and the disease free survival (DFS) were statistically analyzed for twenty one patients with PNETs who underwent surgical intervention in our institute. The patients were divided into 2 groups, G1 NET (grade 1 neuroendocrine tumor: n=11) and G2 NET (grade 2 neuroendocrine tumor: n=10), according to WHO 2010 classification. The radical operation was indicated if curative resection were expected to be achievable. Otherwise,alternative multi-disciplinary treatments were introduced especially for the hepatic metastasis or repeated recurrences. RESULTS Median follow-up period was 37 months (range 7-69). OS was 100% at 3 years and 86% at 5 years. DFS was 62% at 3 years and 39% at 5 years. Disease recurrence developed more frequently in G2 NET, compared to G1 NET. However, there was statistically no difference for the OS between these two groups. CONCLUSIONS Appropriate radical operation with multi-disciplinary treatments could contribute to the patients' survival in the treatment strategy of PNETs.

Abstract
BACKGROUND/OBJECTIVES Our institution has utilized a duodenum-preserving pancreas head resection (DPPHR) procedure for management of low-grade malignant lesions within the head of the pancreas, but this has resulted in a higher rate of postoperative complications, including pancreatic fistula and ischemic bile duct injury. To avoid these complications we recently modified DPPHR to resect all the parenchyma around the pancreatic head and to preserve the epicholedochal plexus around the bile duct. The goal of this study was to investigate outcomes with postoperative complications and disease control following this modified procedure. METHODS Twenty-one consecutive patients underwent DPPHR between 1994 and 2011. Patients were retrospectively classified into one of two groups: the conventional DPPHR group (cDPPHR) or the modified DPPHR group (mDPPHR). Perioperative factors and postoperative complications were compared between these two groups. RESULTS The median age of the 21 patients was 61 (23-77) years, and the median follow-up period was 51 months. Intra-operational blood loss was significantly smaller and duration of hospital stay was significantly shorter in the mDPPHR group than in the cDPPHR group, respectively. The rate of pancreatic fistula was markedly lower in the mDPPHR group (2/13; 15%) than in the cDPPHR group (7/8; 88%) (P = 0.0022). For neoplastic lesions, the surgical margin was negative in all cases, and local recurrence has not occurred in either group. CONCLUSIONS For selected patients, modified DPPHR may provide clinical benefits in terms of less complications associated with shorter hospital stay.

Abstract
In several clinical situations, including resection of malignant or benign biliary lesions, reconstruction of the biliary system using the Roux-en-Y jejunum limb has been adopted as the standard procedure. The basic technique and the procedural knowledge essential for most gastroenterological surgeons are described in this article, along with a video supplement. Low complication rates involving anastomotic insufficiency or stricture can be achieved by using proper surgical techniques, even following small bile duct reconstruction. Using the ropeway method to stabilize the bile duct and jejunal limb allows precise mucosa-to-mucosa anastomosis with interrupted sutures of the posterior row of the anastomosis. Placement of a transanastomotic stent tube is the second step. The final step involves suturing the anterior row of the anastomosis. In contrast to the lower extrahepatic bile duct, the wall of the hilar or intrahepatic bile duct can be recognized within the fibrous connective tissue in the Glissonean pedicle. The portal side of the duct should be selected for the posterior wall during anastomosis owing to its thickness. Meticulous inspection to avoid overlooking small bile ducts could decrease the chance of postoperative intractable bile leakage. In reconstruction of small or fragile branches, a transanastomotic stent tube could work as an anchor for the anastomosis.

Abstract
BACKGROUND/AIMS Little information is available about the long-term prognosis after hepatectomy for liver metastases of neuroendocrine tumors (NETs). To clarify the prognosis for liver metastases of NETs after hepatectomy and to identify a practical and useful surgical indication for hepatic metastases of NETs. METHODOLOGY Twenty-four patients with NET were divided into 2 groups: the nHM group (patients without hepatic metastasis, n=13) and the HM group (patients with hepatic metastasis or recurrences, n=11). Hepatectomy was indicated for metastases or disease recurrences in the liver if R0 resection was expected to be achievable. Patient clinicopathological features, mode of recurrences and treatment for them were evaluated retrospectively. RESULTS The median follow-up period for the 24 patients was 34 months (range 7-69) and the disease specific survival rate was 82% at 5 years. DSS at 5 years did not differ between patients with and without hepatic recurrence (91% vs. 75% respectively, p=0.6144), even though the histological grade and the MIB-1 index were higher in the HM group. CONCLUSIONS Patient prognosis was acceptable following our policy of hepatectomy for NET liver metastases. Survival could be improved by intensive multimodal treatment.

Abstract
BACKGROUND We have already reported the feasibility, safety, and excellent long-term results of distal pancreatectomy with en-bloc celiac axis resection (DP-CAR) for locally advanced pancreatic body cancer. An international standard for the surgical technique of DP-CAR has yet to be established. METHODS DP-CAR was carefully performed in 42 patients in Hokkaido University Hospital from 1998 to July 2007. Arterial blood flow alteration and collateral flow development toward the liver and stomach was obtained following preoperative routine transcatheter arterial embolization of the common hepatic artery. The right-sided approach to the superior mesenteric artery and celiac artery, and the preservation of the inferior pancreatoduodenal artery during the dissection of the plexus around the pancreatic head, are the key techniques in DP-CAR. RESULTS The operative morbidity and mortality were 43 and 4.8%, respectively. R0 resection could be done in 39 (93%) patients. Median operation time and intraoperative blood loss were 478 min and 1030 ml, respectively. Ischemic gastropathy was complicated in 5 (12%) patients, but liver abscess was found in only one patient and no liver failure was encountered. CONCLUSIONS We emphasize again the feasibility and safety of DP-CAR; it should be a treatment of choice for locally advanced pancreatic body cancer.

Abstract
Faecal samples were collected from the rectum of 540 domestic dogs from four districts (Lusaka, Katete, Petauke and Luangwa) in Zambia between 2005 and 2006 and prevalences of canine alimentary tract parasites were determined by coprological examination. Thirteen different ova and parasites including strongyle (43.3%), Spirocerca lupi (18.7%), taeniid (13.1%), Toxocara canis (7.6%), Sarcocystis sp.* (7.5%), Isospora sp.* (5.7%), Physaloptera sp.* (4.6%), Capillaria sp.* (2.8%), Dipylidium caninum (2.2%), Mesocestoides sp.* (2.0%), Ascaris sp.* (1.7%), Trichuris vulpis* (0.4%) and Schistosoma mansoni* (0.4%) were detected, Ascaris and Schistosoma probably originating from coprophagy. The species with asterisks and later-described Taenia multiceps are for the first time reported from dogs in Zambia. A coproantigen enzyme-linked immunosorbent assay (CoproAg-ELISA) developed for Echinococcus spp. revealed 43 positive dogs and 37 of these harboured taeniid eggs. From 63 of the 71 taeniid egg-positive samples, eggs and DNA thereof were isolated and subjected to a multiplex polymerase chain reaction for differentiating E. granulosus sensu lato, E. multilocularis and Taenia spp. Amplicons indicative for Taenia spp. were obtained from 60 samples. Sequencing of amplicons spanning part of the mitochondrial cytochrome c oxidase subunit 1 gene, which was possible with 38 samples, revealed 35 infections with T. hydatigena and 3 with T. multiceps. Therefore, the CoproAg-ELISA showed some positives, but concrete evidence for the existence of canine E. granulosus infection could not be established. Comparison of the results of the CoproAg-ELISA and Taenia species identification indicated that the CoproAg-ELISA cross-reacts with patent infections of T. hydatigena (57%) and T. multiceps (33%).

Abstract
The controversy over whether and how to perform preoperative biliary drainage (PBD) in patients with hilar cholangiocarcinoma (HCA) remains unsettled. Arguments against PBD before pancreatoduodenectomy have recently been gaining momentum. However, the complication-related mortality rate is as high as 10% for patients with HCA who have undergone major liver resection, and liver failure is a major cause of postoperative death. This suggests the need for PBD to treat jaundice in HCA patients scheduled for major surgical resection of the liver and that major surgery should be performed only after the recovery of hepatic function. No definite criteria or guidelines outlining indications for PBD are currently available. In patients with HCA, PBD may be performed by either percutaneous transhepatic biliary drainage (PTBD) or endoscopic biliary drainage (EBD). No consensus, however, has been reached regarding which drainage method is more appropriate. No reported study has compared the effectiveness of PTBD, endoscopic biliary stenting (EBS), and endoscopic nasobiliary drainage (ENBD) in patients with HCA. This review summarizes the results of our study comparing the three methods and outlines the preoperative endoscopic management of segmental cholangitis (SC) in HCA patients undergoing PBD.

Abstract
BACKGROUND/PURPOSE It is important to predict the development of clinically relevant pancreatic fistula (grade B/C) in the early period after pancreaticoduodenectomy (PD). This study has been carried out as a project study of the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHPBS) to evaluate the predictive factors associated with clinically relevant pancreatic fistula (grade B/C). METHOD The data of 1,239 patients from 11 medical institutions who had undergone PD between July 2005 and June 2009 were retrospectively analyzed to review patient characteristics and perioperative and postoperative parameters. RESULTS A drain amylase level >4,000 IU/L on postoperative day (POD) 1 was proposed as the cut-off level to predict clinical relevant pancreatic fistula by the receiver operating characteristic (ROC) curve. The sensitivity, specificity, and accuracy of this cut-off level were 62.2, 89.0, and 84.8%, respectively. A multivariate logistic regression analysis revealed that male [odds ratio (OR) 1.7, P = 0.039], intraoperative bleeding >1,000 ml (OR 2.5, P = 0.001), soft pancreas (OR 2.7, P = 0.001), and drain amylase level on POD 1 >4,000 IU/L (OR 8.6, P < 0.001) were the significant predictive factors for clinical pancreatic fistula. CONCLUSION The four predictive risk factors identified here can provide useful information useful for tailoring postoperative management of clinically relevant pancreatic fistula (grade B/C).

Abstract
Pancreatic endocrine tumors (PETs) are relatively rare. Owing to their slow growing characteristics, an aggressive surgical approach has been considered to improve patients' survival. A case of PET with portal vein (PV) thrombus, successfully treated by distal pancreatectomy with concomitant PV resection and removal of PV tumor thrombus, preserving collateral pathways, is reported.

Abstract
The typical imaging findings of neonatal non-ketotic hyperglycinemia have rarely been described in the radiologic literature with only few individual cases or small series reported. In this article, we present a case of neonatal onset non-ketotic hyperglycinemia, imaged at 6 days of age, and discuss characteristic MRI and MR spectroscopic findings.

Abstract
340 Background: Gallbladder cancer (GBC) is one of the most common malignancies of the biliary tract. Because of the lack of specific presentations, this condition is frequently diagnosed only at an advanced stage. Obstructive jaundice is generally regarded as an indicator of far advanced disease, unresectability, and poor prognosis. The aim of this study was to evaluate clinicopathological factors, especially jaundice, influencing outcome after radical resection of gallbladder cancer, in order to identify the patients benefiting from radical surgery. Methods: Seventy-five patients with GBC underwent surgical resection between 1998 and 2008. A retrospective analysis was conducted on sixty-four patients with UICC T2 or more tumors. Clinicopathologic features, extents of resection, and survival rates were investigated retrospectively. Obstructive jaundice was defined that serum T-bil level was more than 2.0 mg/ml. Patients with jaundice underwent ENBD or PTBD and curative resection was performed when serum T-Bil level decreased below 2.0 mg/ml. Right after laparotomy, para-aortic lymphadenectomy and frozen section pathology were performed to convert a radical resection to a palliative procedure when a para-aortic lymph node was positive. Results: The three and five-year disease-specific survival rates were 47% and 41%, respectively. Nine patients survived for more than five years.Univariate analysis showed that blood loss during operation, hepatic invasion, portal vein invasion, N category, M category after postoperative pathological examination and residual tumor were significant prognostic factors (p<0.05), but multivariate analysis showed that M category only was independent prognostic factor (p<0.05). Five-year disease-specific survival rates for patients with (n=37) and without (n=27) obstructive jaundice were 47% and 35%, respectively (p=0.69). Conclusions: Obstructive jaundice had no impact on postoperative survival as long as metastatic disease was exclueded and adequate resection of the hepatic hilum was performed. Aggressive surgery might bring long-term survival in selected patients even with obstructive jaundice by advanced gallbladder cancer. No significant financial relationships to disclose.

Abstract
We measured kinetic energies of the fragment ions of argon dimers multiply ionized by low-energy Ar(9+) collisions. For (Ar2)(4+) dissociation, the asymmetric channel (Ar(3+) + Ar(+)) yield is found unexpectedly higher than the symmetric channel (Ar(2+) + Ar(2+)) yield in contrast with previous observation for covalent molecules or clusters. For the dissociation channel (Ar2)(2+)→Ar(+) + Ar(+), two well-separated peaks were observed, clearly evidencing that the direct Coulombic dissociation and the radiative charge transfer followed by ionic dissociation alternatively occur for the dicationic dimers. The respective intensity of these two peaks provides a direct mean to unravel the respective proportion of one-site and two-site double-electron capture, which are found equal for this collision system.
