Abstract
BACKGROUND Although the associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) induces more rapid liver regeneration than portal vein embolization, the mechanism remains unclear.
AIM To assess the influence of inflammatory cytokines and endothelial nitric oxide synthase (eNOS) activation on liver regeneration in ALPPS.
METHODS The future liver remnant/body weight (FLR/BW) ratio, hepatocyte proliferation, inflammatory cytokine expression, and activation of the Akt-eNOS pathway were evaluated in rat ALPPS and portal vein ligation (PVL) models. Hepatocyte proliferation was assessed based on Ki-67 expression, which was confirmed using immunohistochemistry. The serum concentrations of inflammatory cytokines were measured using enzyme linked immune-solvent assays. The Akt-eNOS pathway was assessed using western blotting. To explore the role of inflammatory cytokines and NO, Kupffer cell inhibitor gadolinium chloride (GdCl3), NOS inhibitor N-nitro-arginine methyl ester (L-NAME), and NO enhancer molsidomine were administered intraperitoneally.
RESULTS The ALPPS group showed significant FLR regeneration (FLR/BW: 1.60% ± 0.08%, P < 0.05) compared with that observed in the PVL group (1.33% ± 0.11%) 48 h after surgery. In the ALPPS group, serum interleukin-6 expression was suppressed using GdCl3 to the same extent as that in the PVL group. However, the FLR/BW ratio and Ki-67 labeling index were significantly higher in the ALPPS group administered GdCl3 (1.72% ± 0.19%, P < 0.05; 22.25% ± 1.30%, P < 0.05) than in the PVL group (1.33% ± 0.11% and 12.78% ± 1.55%, respectively). Phospho-Akt Ser473 and phospho-eNOS Ser1177 levels were enhanced in the ALPPS group compared with those in the PVL group. There was no difference between the ALPPS group treated with L-NAME and the PVL group in the FLR/BW ratio and Ki-67 labeling index. In the PVL group treated with molsidomine, the FLR/BW ratio and Ki-67 labeling index increased to the same level as in the ALPPS group.
CONCLUSION Early induction of inflammatory cytokines may not be pivotal for accelerated FLR regeneration after ALPPS, whereas Akt-eNOS pathway activation may contribute to accelerated regeneration of the FLR.

Abstract
Technique for preserving limited number of human spermatozoa is important for successful treatment of patients with azoospermia and cryptozoospermia. This study determined whether the non-biological devices (Cryotop and Cell Sleeper) efficiently vitrify small numbers of human spermatozoa. From December 2011 to December 2018, 10 males with very low sperm numbers managed with a single sperm vitrification method. Post-warmed sperm recovery was similar with both devices. Post-warmed sperm motility and fertilization after intracytoplasmic sperm injection were significantly higher in Cryotop group than in Cell Sleeper group (40.0% vs. 22.0%, P < 0.01 and 50.7% vs. 21.7%, P < 0.01, respectively). The pregnancy rate was 15.4% and 2 healthy babies were born in the Cryotop, while 14.3% and 1 baby in the Cell Sleeper, which did not differ between the groups. Both devices have clinical advantages in terms of easy use and safety, and would be performed more efficiently by using devices with different properties.

Abstract
Abstract
Extramedullary hematopoiesis (EMH) is the proliferation of hematopoietic stem cells outside the bone marrow and often observed in the liver, spleen in association with myeloproliferative disorders. On the other hand, EMH in the gastric wall is extremely rare. We report a rare case of EMH foci coexisting with early gastric cancer, which resulted in severe gastrointestinal bleeding. A 70-year-old male was diagnosed with myelofibrosis 4 years ago and visited our emergency room with a complaint of hematemesis and tarry stools. Upper gastrointestinal endoscopy revealed three early-stage gastric cancers in the lower gastric body and antrum, and biopsy was performed. Persistent bleeding at the biopsy site of the hypogastric lesion led to the consideration of surgical intervention. An open distal gastrectomy was performed. Postoperative histopathological examination revealed the tumor of the lower gastric body had EMH foci associated with myelofibrosis.

Abstract
This report shows a case with a rare small-sized lung adenocarcinoma that rapidly progressed from a nonsolid nodule (NSN) to a solid nodule (SON) over a period of just 1 year after a very long-term observation from its first detection. In 2007, the patient was an asymptomatic 52-year-old man at the time of the first detection via chest low-dose computed tomography (CT) screening as part of a periodic medical checkup at our hospital. It revealed an abnormal shadow in another location of the lung field, necessitating a more thorough examination. Then, he visited our outpatient clinic for the first time and a workup examination was performed using thin-section CT (TSCT) images, which incidentally detected a small NSN with a maximum diameter of 1.2 cm in the mid-zone of the left upper lung field. Since it did not disappear in the periodic subsequent workup examinations, the patient was informed of the suspicious early lung adenocarcinoma each time; however, the patient desired to continue watchful waiting. The radiographical properties of the NSN remained almost unchanged until 2019, but in 2020, the inside of the nodule showed a skip-like change to a SON. Finally, because of the unexpectedly fast transition, consent for lobectomy could be obtained. Surgery was then performed, 13 years after its first detection, at an age of 65 years. The pathological findings revealed a 1.2 cm, pT1bN0M0, pStage IA2-adenocarcinoma, which was 90% of the acinar subtype with positive vascular permeation. Management of a NSN, that does not resolve and/or change, must continue watchful waiting, and at the very least continue follow-up with TSCT observation to ensure the safe and appropriate timing of excision using imaging as a marker of transition.

Abstract
INTRODUCTION The usefulness of adjuvant chemotherapy in biliary tract cancer (BTC) is poorly reported. This study aimed to evaluate the effectiveness and safety of adjuvant gemcitabine plus S-1 (GS) chemotherapy after curative surgical resection for BTC. METHODS 225 BTC patients who underwent surgical resection between January 2006 and May 2019 were enrolled in this study. Twenty-seven patients received adjuvant chemotherapy with GS (GS group), whereas 67 patients underwent surgery alone (S group). Twenty-three matching pairs were derived through propensity score (PS) matching analysis. Patients received 12 cycles of adjuvant chemotherapy (70 mg/m2 oral S-1 for 7 consecutive days plus intravenous gemcitabine 1,000 mg/m2 on day 7). The primary end point was recurrence-free survival (RFS). The secondary end points were the 1-, 2-, and 3-year RFS and overall survival (OS) rates, tolerability, and frequency of grade 3/4 toxicity. RESULTS The completion rate was 81.5%; no treatment-related deaths were observed. Grade 3/4 adverse events were seen in 40.7% of the patients. RFS (3-year RFS rate: 59.3% vs. 39.1%, p = 0.049) and OS (3-year OS rate: 71.7% vs. 53.4%, p = 0.008) were significantly better in the GS group than in the S group among PS-matched pairs. DISCUSSION/CONCLUSION GS chemotherapy after curative surgery was well tolerated, showed better clinical benefit in the adjuvant setting, and can effectively reduce BTC recurrence.

Abstract
PURPOSE This study determined the effect of laser-assisted hatching on the clinical and neonatal outcomes of single vitrified blastocyst transfer. METHODS From June 2014 to March 2018, 289 matched pairs after propensity score matching were analyzed. During the blastocyst warming procedure, a small section of the zona pellucida area in the empty perivitelline space was sliced off using multiple laser beams. The clinical and neonatal outcomes of the laser-treated group and non-treatment control were analyzed. RESULTS In the laser-assisted hatching group, significantly higher rates of clinical pregnancy (40.8% vs 29.4%, P < .01) and live delivery (34.3% vs 22.5%, P < .01) were observed compared to the control group. Other variables such as the average gestational weeks, the sex of the baby, birthweight, or congenital malformations were found to have no significant differences in neonatal outcomes. Moreover, all babies were singleton live births. CONCLUSIONS Single vitrified blastocyst transfer treated with laser-assisted hatching increases the live birth rate and has no adverse effects on neonatal outcomes.

Abstract
Background Peritoneal recurrence of hepatocellular carcinoma (HCC) after hepatectomy occurs rarely, accounting for less than 1% of all recurrences. Reported causes of such dissemination include a history of rupture of the original HCC, needle biopsy or puncture treatment, and surgical procedures. There is no consensus on the optimal treatment strategy for peritoneal dissemination. There have been few reports on assisting resection of peritoneal dissemination by using indocyanine green (ICG) fluorescence. Case presentation A 57-year-old man underwent posterior sectionectomy for HCC. Six months later, computed tomography revealed multiple nodules suspected of indicating peritoneal dissemination. Various preoperative imaging studies demonstrated only four nodules, the doubling time of the tumors being rapid at 22 days. The nodules were therefore resected. ICG (0.5 mg/kg) was injected intravenously 2 days before the procedure, enabling identification of the nodules by their brightness in the operative field under near-infrared lighting. A total of eight lesions were detected during the procedure and resected, some of which had not been identified by preoperative imaging studies. We diagnosed peritoneal dissemination of HCC based on the pathological findings and their similarity to those of the original HCC. We concluded that the recurrences were likely attributable to exposure of the tumor to the serosa at the time of the original operation. Conclusions Although ICG fluorescence is useful for identifying peritoneal dissemination of HCC, attention should be paid to the difficulty in detecting deep lesions and occurrence of false positives.

Abstract
BACKGROUND Although hepatopancreatoduodenectomy (HPD) is the only means of achieving R0 resection of widespread extrahepatic cholangiocarcinoma, its safety and oncological benefit remain controversial because of its inherent high risk of mortality and morbidity. OBJECTIVE The aim of this study was to retrospectively analyze short- and long-term outcomes and evaluate the safety and oncological benefit of this advanced procedure. METHODS The study cohort comprised 37 consecutive patients who had undergone major HPD. Portal vein embolization was performed before surgery in 20 (54%) patients with future remnant liver volume < 35%. RESULTS The median operative time and blood loss were 866 min and 1000 mL, respectively. Concomitant vascular resection was performed in five patients (14%). The overall morbidity and mortality rates were 100% and 5.4% (n = 2), respectively. Nineteen patients (51%) had major (Clavien-Dindo grade III or higher) complications, the most common being intra-abdominal infection (49%) and post-hepatectomy liver failure (46%, grade B/C: 32%/5%), followed by postoperative pancreatic fistula (30%, grade B/C). R0 resection was achieved in 31 patients (84%). The 1-, 3-, and 5-year overall survival (OS) rates were 83%, 48%, and 37%, respectively. In patients with R0 resection, 5-year OS was comparable between patients who had undergone major HPD and major hepatectomy alone (41% vs. 40%, p = non-significant). CONCLUSIONS HPD is a valid treatment option for extensive cholangiocarcinoma, offering long-term survival benefit at the cost of relatively high but acceptable morbidity and mortality rates. HPD is advocated in selected patients provided that it is considered possible to achieve R0 resection.

Abstract
BACKGROUND Systemic inflammation may have prognostic value in some malignancies and association with lymph node metastasis. This study aimed to evaluate the impact of systemic inflammatory biomarkers on long-term and oncological outcomes as well as to assess the association between biomarkers with lymph node metastasis in extrahepatic cholangiocarcinoma patients. METHODS We enrolled 271 consecutive patients who underwent surgical resection for extrahepatic cholangiocarcinoma. Poor prognostic factors were compared to identify the biomarkers that were most associated with overall survival (OS) and disease-free survival (DFS) using receiver operating characteristic curves and multivariable analysis. Furthermore, we evaluated the relationship between biomarkers and lymph node metastasis. RESULTS Four and two biomarkers were predictive for OS and DFS, respectively, among which, the C-reactive protein-to-albumin ratio (CAR) had the highest area under the curve values (OS: 0.631, DFS: 0.624). Multivariable analysis showed that a high CAR was an independent prognostic factor for both OS and DFS (P = .002 and P < .001, respectively). Although a high CAR was not significantly correlated with lymph node metastasis (P = .645), carbohydrate antigen 19-9 showed a significant correlation (P < .001). CONCLUSIONS Preoperative CAR is the most accurate prognostic factor for OS and DFS in extrahepatic cholangiocarcinoma patients and is independent of lymph node metastasis.

Abstract
PURPOSE Prolonged exposure to equilibration solutions may be detrimental to an embryo's developmental potential, whereas a shorter exposure may affect the penetration of cryoprotectants into blastomeres. The purpose of this study was to evaluate the effects of different equilibration times on the clinical and neonatal outcomes of human blastocyst vitrification. METHODS This is a retrospective study based on data collected between November 2008 and November 2015. A total of 192 blastocysts (80 non-expanded and 112 expanded) obtained from 167 patients were analyzed. The blastocysts were divided into two groups according to their equilibration time: 8-11 minutes or 12-15 minutes. The clinical and neonatal outcomes of warmed blastocysts were evaluated. RESULTS The survival, implantation, and live birth rates of non-expanded blastocysts were not different between the two groups, but they significantly improved for the expanded blastocysts in the 12-15 minutes group compared to the 8-11 minutes group. The results were similar for the neonatal outcomes after vitrified embryo transfer, when partitioned by equilibration time and blastocyst stage at vitrification. CONCLUSIONS For the non-expanded blastocysts, a shortened equilibration time (8-11 minutes) is sufficient for effective vitrification.

Abstract
BACKGROUND Splenic vein stenosis and occlusion, which are known causes of left-sided portal hypertension, often occur secondary to trauma, pancreatitis, or invasion or compression by pancreatic tumors. However, few reports have described idiopathic splenic vein stenosis. CASE PRESENTATION A 70-year-old man was referred to our hospital for examination of isolated gastric varices. He had no history of liver disease, pancreatitis, or abdominal trauma. Computed tomography revealed stenosis of almost the entire length of the splenic vein, and development of gastric fundal and short gastric varices. No inflammatory changes or neoplastic lesions of the pancreas were observed in any imaging study. The patient was diagnosed with left-sided portal hypertension caused by idiopathic splenic vein stenosis, and splenectomy was performed. The postoperative course was smooth, and improvement of the gastric varices was shown by upper gastrointestinal endoscopy at 3 months after the operation. CONCLUSIONS Idiopathic splenic vein stenosis is an extremely rare cause of left-sided portal hypertension. Splenectomy is one of the most effective treatments for left-sided portal hypertension caused by idiopathic splenic vein stenosis.

Abstract
PURPOSE Limited research has been published on the effect of piezo-assisted intracytoplasmic sperm injection (P-ICSI). We evaluated the effect of P-ICSI on the laboratory, clinical, and neonatal outcomes. METHODS This retrospective study was based on the data collected between April 2011 and October 2016. Total 1348 mature oocytes from 145 patients were analyzed. Laboratory, clinical, and neonatal outcomes of those given conventional intracytoplasmic sperm injection (C-ICSI) and those administered P-ICSI were examined. RESULTS P-ICSI showed significantly more favorable results, with a survival rate of 97.0% (C-ICSI: 94.1%, P < .010) and a fertilization rate of 83.5% (C-ICSI: 70.6%, P < .001). There were no differences in the blastocyst development rate, implantation rate, miscarriage rate, live birth rate, gestational age, birth weight, proportion of male neonates, cesarean section rate, and congenital abnormalities between the two patient groups. CONCLUSIONS Our comparison of P-ICSI with C-ICSI showed that P-ICSI significantly improved the survival and fertilization.

Abstract
132 Background: The impact of adjuvant chemotherapy for advanced biliary cancer remains controversial. We previously failed to show survival benefit of adjuvant gemcitabine chemotherapy (UMIN000014018). The aim of this study was to evaluate the safety and efficacy of adjuvant gemcitabine plus S-1 chemotherapy after surgical resection for advanced biliary cancer. Methods: Between January 2006 and May 2019, a total of 110 patients who underwent surgical resection for biliary cancer (UICC Stage II or more) were enrolled in this study. Of these, 33 patients subsequently received 12 cycles of adjuvant chemotherapy (GS group), and 77 patients underwent surgery alone (S group). A cycle of chemotherapy consisted of oral S-1 70mg/m2 for 7 consecutive days and intravenous gemcitabine 1000mg/m2 on day 7, followed by a 1-week break from chemotherapy. Clinicopathological factors and patient survival were compared between the two groups. Results: GS group had significantly younger patients ( P = 0.036) and higher UICC T factor ( P = 0.001). Surgical procedure was significantly different in the two groups (P = 0.010). Other patient demographics and tumor characteristics were similar between the two groups. The completion rate of adjuvant chemotherapy was 57.6%, and there was no treatment-related deaths. All grades and grade 3/4 adverse event were seen in 60.6% and 33.3%, respectively. Three-year recurrence-free and overall survival rates were significantly higher in GS group than S group (61.9% vs. 34.4%, P = 0.016; 77.6% vs. 39.7%, P < 0.001, respectively). Conclusions: Adjuvant chemotherapy using gemcitabine plus S-1 was well tolerated and it would be an effective treatment strategy for the patients with resected advanced biliary cancer. Based on these results, randomized controlled study should be warranted.

Abstract
PURPOSE Microsuction (MS) is a technique for mechanically emptying fluid from blastocele using a microneedle. In this study, we evaluated the improvement in clinical and neonatal outcomes of vitrified blastocyst transfer programs when MS of blastocelic fluid was used before vitrification. METHODS This was a retrospective study based on data collected between March 2014 and August 2016. A total of 317 blastocysts obtained from 211 patients were analyzed. The blastocelic fluid of expanded blastocysts was aspirated completely, and blastocysts were collapsed prior to vitrification. Clinical and neonatal outcomes of warmed blastocysts were compared. RESULTS The survival rate of the MS blastocyst was significantly higher compared with the nontreatment control (98.7% vs 89.3%, OR: 9.34, 95% CI: 2.35-36.8, P < 0.01). The rates of implantation and live birth were higher in the MS group than in the control group, but the differences were not significant. There were no differences in gestational age, birthweight, proportion of male babies, rates of cesarean section, and congenital abnormalities. CONCLUSION The MS procedure improved blastocyst survival and had little effect on further embryo development after warming.

Abstract
BACKGROUND How increasing age affects the characteristics of groin hernia remains uncertain. This study evaluated the association between age and the type of groin hernia, especially with respect to its multiplicity, observed during laparoscopic transabdominal preperitoneal (TAPP) hernia repair. METHODS We retrospectively evaluated 634 consecutive patients with primary groin hernia who underwent laparoscopic TAPP repair between October 2000 and June 2017. Patients were stratified into 4 age groups: < 60 years, 60-69 years, 70-79 years, and 80 years or older. RESULTS The incidence of occult contralateral hernia and multiple ipsilateral hernias increased significantly with each increasing age group: 7.3%, 10.4%, 12.7%, and 20.8% for occult contralateral hernia (p = 0.005), and 5.6%, 9.2%, 16.8%, and 21.7% for multiple ipsilateral hernias (p < 0.001), respectively. Univariate analyses showed that an older age (age ≥ 70 years) was the only factor significantly associated with the presence of multiple groin hernias (odds ratio, 2.69; 95% confidence interval, 1.89-3.81; p < 0.001). In patients with multiple ipsilateral hernias, the prevalent form in men was a pantaloons hernia, with an incidence of about 70% across all age groups, whereas in women it was groin hernias, with one component being a femoral hernia, an obturator hernia, or both. CONCLUSIONS The multiple occurrence of groin hernias, either unilaterally or bilaterally, was a clinical feature in the elderly.

Abstract
It is unclear whether multiple nonstructural (NS) 5A resistance-associated substitutions (RASs) correlate with the outcome of sofosbuvir (SOF) and ledipasvir (LDV) therapy. We investigated the effects of multiple NS5A RASs in NS5A inhibitor-naïve patients with chronic hepatitis C virus genotype 1b infection treated with SOF/LDV. In 313 patients treated with SOF/LDV, we assessed the effects of multiple NS5A RASs on the sustained virological response (SVR). RASs at L28, R30, L31, Q54, P58, Q62, A92, and Y93 in the NS5A region were examined by direct sequencing. The prevalence of RASs was as follows: 2.6% at L28, 8.7% at R30, 6.1% at L31, 48.7% at Q54, 9.9% at P58, 9.9% at Q62, 5.1% at A92, 13.8% at Y93, and 19.2% at L31 or Y93. A total of 133 patients had no RASs. SVR was achieved in 98.7% of the patients. SVR rates significantly differed between patients with and without the L31 or Y93 RAS (93.0% [53/57] vs 100% [250/250], P = .0011). In addition, among patients with the L31 or Y93 RAS, 29.8%, 45.6% and 24.6% had one, two and three or more NS5A RASs, respectively. The SVR rate was significantly lower in patients with the L31 or Y93 RAS with more than three NS5A RASs compared to those with fewer than three NS5A RASs (71.4% [10/14] vs 100% [43/43], P = .0025). Although the prevalence of multiple NS5A RASs at baseline was low in NS5A inhibitor-naïve patients, the presence of multiple NS5A RASs was associated with the effectiveness of SOF/LDV therapy.

Abstract
Cholangiocarcinoma (CCC) is a strongly aggressive malignancy for which surgical resection is the only potential curative therapy. Sorafenib, a multikinase inhibitor of the RAF/MEK/ERK pathway, is a molecular-targeted drug that is approved for hepatocellular carcinoma (HCC) but not for CCC. The differences in signaling pathway characteristics under sorafenib treatment between HCC (HLF, Huh7, PLC/PRF/5) and CCC (RBE, YSCCC, Huh28) cell lines were therefore investigated using cell proliferation, western blotting, and apoptosis analyses. Sorafenib inhibited cell growth significantly less in CCC cells than in HCC cells, with lower suppression of ERK phosphorylation. Significantly decreased AKT Ser473 phosphorylation in HCC cells, and conversely enhanced phosphorylation of AKT Ser473 and mTORC2 in CCC cells, were observed with sorafenib treatment. Disassembly of the mTORC2 complex in RBE cells with siRNA targeting Rictor resulted in the downregulation of AKT Ser473 phosphorylation and enhanced apoptosis presumably via increased FOXO1, which consequently suppressed RBE cell proliferation. Phosphorylation of mTORC1 and autophagy were not influenced by sorafenib in CCC cells. Simultaneous administration of everolimus to suppress activated mTORC1 in RBE cells revealed that combined everolimus and sorafenib treatment under mTORC2 disassembly could enhance growth inhibition through the suppression of both sorafenib- and everolimus-dependent AKT Ser473 phosphorylation in addition to the inhibition of mTORC1 phosphorylation. Prevention of escape by AKT/mTOR signaling from the RAF/MEK/ERK pathway in sorafenib treatment by suppressing mTORC2 activity may lead to promising new approaches in CCC therapy.

Abstract
BACKGROUND The severity of liver fibrosis has been reported to be correlated with the risk of intractable ascites after hepatectomy for hepatocellular carcinoma. Since 2009, we have measured routinely the serum concentrations of type IV collagen 7s domain (7s collagen), a biochemical marker of liver fibrosis and applied limited resection to patients with elevation of the serum 7s collagen concentrations above the upper limit of normal (6.0 ng/mL). The aim of this study was to assess the potential benefits of our treatment strategy on the postoperative outcomes of patients with hepatocellular carcinoma. METHODS A propensity score-matched analysis was performed to compare the outcomes between patients who underwent initial hepatectomy for hepatocellular carcinoma before or after 2009 (2009 to April 2015; period 2) and those who underwent the operation prior to 2009 (1990-2008; period 1; n = 129 in each period). RESULTS The incidence of intractable ascites was significantly lower in period 2 than in period 1 (2.3 vs 14.7%; P < .001), although the other short-term and long-term outcomes were comparable between the 2 groups. A multivariate analysis identified elevation of the serum 7s collagen concentrations to ≥7.4 ng/mL as an independent predictor of IA (odds ratio 14.1, 95% confidence interval 2.8 to 106.7; P = .001), with the area under the receiver-operating characteristic curve of 0.820 (0.648-0.919, P = .005). CONCLUSION Modification of the surgical procedure according to the serum 7s collagen concentration is beneficial for reducing the risk of development of intractable ascites after hepatectomy for hepatocellular carcinoma.

Abstract
We have developed a focusing system for extreme ultraviolet light produced by high-order harmonic generation. An ellipsoidal mirror with a precise surface shape was fabricated and installed into the focusing system. A rigid mirror manipulator and a beam profiler were employed to perform precise and stable mirror alignment. As a demonstration of the focusing performance, high-order harmonics in the wavelength range of 13.5-19.5 nm were successfully focused into a 2.4 × 2.3 μm(2) spot.

Abstract
BACKGROUND/OBJECTIVES The aim of this study was to evaluate the impact of the pancreatic signal intensity (SI) on magnetic resonance imaging (MRI) findings for predicting the development of pancreatic fistula (PF) after a distal pancreatectomy (DP) involving a triple-row stapler closure. METHODS A multivariate logistic regression analysis was used to identify risk factors for clinical PF, as defined by the International Study Group on Pancreatic Fistula grade B or C. The pancreas-to-muscle SI ratio was evaluated using fat-suppressed T1-weighted MRI. RESULTS Of the 41 enrolled patients, 8 (19.5%) developed clinical PF. The pancreatic thickness (≥15 mm) and SI ratio (≥1.3) were identified as independent predictors of clinical PF in a multivariate analysis. Clinical PF was observed in one patient with a thick pancreas and a low SI ratio (14.3%), whereas it was observed in 60% of the patients with a thick pancreas and a high SI ratio. The area under the receiver operating characteristic curve for a predictive model consisting of the two factors was 0.87 (95% confidence interval, 0.75 to 0.99), the level of which tended to be greater than that for pancreatic thickness alone (0.81, p = 0.09). CONCLUSIONS The SI ratio as evaluated using MRI might be useful for predicting clinical PF in patients with the pancreatic thickness ≥15 mm after DP involving a stapler closure.

Abstract
BACKGROUND Among the intrahepatic bile ducts, the biliary system of the left medial sectional bile duct (B4) is known to have relatively complex patterns. METHODS The records of 500 patients who had been diagnosed as having hepato-pancreatico-biliary disease were retrospectively studied for anatomical biliary variations of the left liver with special reference to the drainage system of B4 using magnetic resonance images. RESULTS The left hepatic duct was present in 494 patients (98.8%), whereas it was lacking in 6 patients (1.2%), and these patients exhibited the following B4 confluence patterns: B4 drained into the common hepatic duct in 2 patients (.4%), the right anterior sectional bile duct in 3 patients (.6%), and the right posterior sectional bile duct in 1 patient (.2%). The left hepatic duct was absent more frequently in patients with portal venous variations than in patients with a common branching pattern (8.2% vs .4%, P = .0011). CONCLUSION The presently reported data are useful for obtaining a better understanding of the surgical anatomy of the biliary system of the left liver.

Abstract
PURPOSE To evaluate the features of hepatic congestion on gadoxetate disodium (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) and the mechanisms responsible for the radiological findings in a rat model of partial liver congestion. MATERIALS AND METHODS A conventional T1 -weighted spin-echo sequence of the liver was performed using a 1.5T magnetic resonance imager with an 80-mm magnetic aperture for animal studies. We induced regional congestion using partial left lateral hepatic vein ligation (n = 5) and evaluated the following in both congestive liver (CL) and noncongestive liver (non-CL): 1) chronological changes in the relative enhancement (RE) up to 60 minutes after Gd-EOB-DTPA administration, and 2) mRNA and protein expression of rat organic anion transporting protein 1a1 (Oatp1a1). RESULTS The RE in the CL reached a small peak (18%) at 5 minutes, corresponding to approximately half of the value observed in the non-CL, then slowly decreased in a linear manner thereafter. The degree of RE in the CL was significantly lower than that in the non-CL for up to 30 minutes (P < 0.05). An immunohistological examination showed that Oatp1a1 protein expression was downregulated in the CL. The mRNA level of Oatp1a1 in the CL was significantly upregulated, compared with that in control rat liver (P = 0.046), whereas no significant difference was observed between the CL and the non-CL (P = 0.698). CONCLUSION The reduced signal intensity in the CL on Gd-EOB-DTPA-enhanced MRI could be explained by the decreased uptake of Gd-EOB-DTPA via Oatp1a1 protein in the congestive area.
