| 1 | Endoscopic diagnosis of pancreaticobiliary maljunction显示文摘Pancreaticobiliary maljunction (PBM) is a congenital anomaly defined as a junction of the pancreatic and bile ducts located outside the duodenal wall, usually forming a markedly long common channel. As the action of the sphincter of Oddi does not functionally affect the junction in PBM patients, continuous pancreatobiliary reflux occurs, resulting in a high incidence of biliary cancer. PBM can be divided into PBM with biliary dilatation (congenital choledochal cyst) and PBM without biliary dilatation (maximal diameter of the bile duct ≤ 10 mm). The treatment of choice for PBM is prophylactic surgery before malignant changes can take place. Endoscopic retrograde cholangiopancreatography (ERC P) is the most effective examination method for close obs ervation of the pattern of the junction site. When the communication between the pancreatic and bile ducts is maintained, despite contraction of the sphi ncter on ERCP, PBM is diagnosed. In these pat ients, levels of pancreatic enzymes in the bile are gene rally elevated, due to continuous pancreatobiliary reflux via a long common channel. Magnetic resonance cholangiopancreatography and 3D-computed tomography can diagnose PBM, based on findings of an anomalous union between the common bile duct and the pancreatic duct, in addition to a long common channel. Endoscopic ultrasonography and intraductal ultra sonography can demonstrate the junction outside the duodenal wall, and are useful for the diagnosis of asso ciated biliary cancer. Gallbladder wall thickness on ultra so nography can be a screening test for PBM. | Terumi Kamisawa Kensuke Takuma Fumihide Itokawa Takao Itoi | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，1： | 25 |
| 2 | Liquid biopsy in patients with hepatocellular carcinoma: Circulating tumor cells and cell-free nucleic acids显示文摘Hepatocellular carcinoma(HCC), with its high incidence and mortality rate, is one of the most common malignant tumors. Despite recent development of a diagnostic and treatment method, the prognosis of HCC remains poor. Therefore, to provide optimal treatment for each patient with HCC, more precise and effective biomarkers are urgently needed which could facilitate a more detailed individualized decision-making during HCC treatment, including the following; risk assessment, early cancer detection, prediction of treatment or prognostic outcome. In the blood of cancer patients, accumulating evidence about circulating tumor cells and cell-free nucleic acids has suggested their potent clinical utilities as novel biomarker. This concept, so-called 'liquid biopsy' is widely known as an alternative approach to cancer tissue biopsy. This method might facilitate a more sensitive diagnosis and better decision-making by obtaining genetic and epigenetic aberrations that are closely associated with cancer initiation and progression. In this article, we review recent developments based on the available literature on both circulating tumor cells and cell-free nucleic acids in cancer patients, especially focusing on Hepatocellular carcinoma. | wataru okajima shuhei komatsu daisuke ichikawa mahito miyamae takuma ohashi taisuke imamura jun kiuchi keiji nishibeppu tomohiro arita hirotaka konishi atsushi shiozaki ryo morimura hisashi ikoma kazuma okamoto eigo otsuji | 2017 | World Journal of Gastroenterology2017，23，31： | 22 |
| 3 | Strategy to differentiate autoimmune pancreatitis from pancreas cancer显示文摘Autoimmune pancreatitis (AIP) is a newly described entity of pancreatitis in which the pathogenesis appears to involve autoimmune mechanisms. Based on histological and immunohistochemical examinations of various organs of AIP patients, AIP appears to be a pancreatic lesion reflecting a systemic 'IgG4-related sclerosing disease'. Clinically, AIP patients and patients with pancreatic cancer share many features, such as preponderance of elderly males, frequent initial symptom of painless jaundice, development of new-onset diabetes mellitus, and elevated levels of serum tumor markers. It is of uppermost importance not to misdiagnose AIP as pancreatic cancer. Since there is currently no diagnostic serological marker for AIP, and approach to the pancreas for histological examination is generally difficult, AIP is diagnosed using a combination of clinical, serological, morphological, and histopathological features. Findings suggesting AIP rather than pancreatic cancer include:fluctuating obstructive jaundice; elevated serum IgG4 levels; diffuse enlargement of the pancreas; delayed en- hancement of the enlarged pancreas and presence of a capsule-like rim on dynamic computed tomography; low apparent diffusion coefficient values on diffusion-weighted magnetic resonance image; irregular narrowing of the main pancreatic duct on endoscopic retrograde cholangiopancreatography; less upstream dilatation of the main pancreatic duct on magnetic resonance cholangiopancreatography, presence of other organ involvement such as bilateral salivary gland swelling, retroperitoneal fibrosis and hilar or intrahepatic sclerosing cholangitis; negative work-up for malignancy including endoscopic ultrasound-guided fine needle aspiration; and steroid responsiveness. Since AIP responds dramatically to steroid therapy, accurate diagnosis of AIP can avoid unnecessary laparotomy or pancreatic resection. | Kensuke Takuma Terumi Kamisawa Rajesh Gopalakrishna Seiichi Hara Taku Tabata Yoshihiko Inaba Naoto Egawa Yoshinori Igarashi | 2012 | World Journal of Gastroenterology2012，18，10： | 20 |
| 4 | Nonalcoholic steatohepatitis-associated hepatocellular carcinoma:Our case series and literature review显示文摘Recently,nonalcoholic steatohepatitis(NASH) has been considered to be another cause of liver cirrhosis and hepatocellular carcinoma(HCC).The natural history and prognosis of NASH are controversial.Accordingly,we assessed the clinicopathological features of NASH-associated HCC in our experience and reviewed the literature of NASH-associated HCC.We experienced 11 patients with NASH-associated HCC(6 male,5 female;mean age 73.8 ± 4.9 years) who received curative treatments.Most(91%) patients had been diagnosed with obesity,diabetes,hypertension,or dyslipidemia.Seven patients(64%) also had a non-cirrhotic liver.The recurrence-free survival rates at 1,3 and 5 years were 72%,60%,and 60%.We also summarized and reviewed 94 cases of NASH-associated HCC which were reported in the literature(64 male;mean age 66 years).The majority of patients(68%) were obese,66% of patients had diabetes,and 24% had dyslipidemia.Furthermore,26% of the HCCs arose from the non-cirrhotic liver.In conclusion,patients with non-cirrhotic NASH may be a high-risk group for HCC,and regular surveillance for HCC is necessary in non-cirrhotic NASH patients as well as cirrhotic patients. | Yoshitaka Takuma Kazuhiro Nouso | 2010 | World Journal of Gastroenterology2010，16，12： | 17 |
| 5 | Comprehensive and innovative techniques for livertransplantation in rats: A surgical guide显示文摘AIM: To investigate our learning curves of orthotopic liver transplantation (OLT) in rats and the most important factor for successful surgery. METHODS: We describe the surgical procedures for our rat OLT model, and determined the operator learning curves. The various factors that contributed to successful surgery were determined. The most important surgical factors were evaluated between successful and unsuccessful surgeries.RESULTS: Learning curve data indicated that 50 cases were required for operator training to start a study. Operative time, blood loss, warm ischemic time, anhepatic phase, unstable systemic hemodynamic state, and body temperature after surgery significantly affected surgery success by univariate analysis, while the anhepatic phase was the most critical factor for success by multivariate analysis. CONCLUSION: OLT in rats is the only liver transplantation model that provides clinically relevant and reliable results. Shortened anhepatic phase is key to success in this model. | Tomohide Hori Justin H Nguyen Yasuhiro Ogura Toshiyuki Hata Shintaro Yagi Ann-Marie T Baine Norifumi Ohashi Christopher B Eckman Aimee R Herdt Hiroto Egawa Yasutsugu Takada Fumitaka Oike Seisuke Saka-moto Mureo Kasahara Kohei Ogawa Koichiro Hata Taku Iida Yukihide Yonekawa Lena Sibulesky Kagemasa Kuribayashi Takuma Kato Kanako Saito Mie Torii Naruhiko Sahara Naoko Kamo Tomoko Sahara Motohiko Yasutomi Shinji Uemoto | 2010 | World Journal of Gastroenterology2010，16，25： | 14 |
| 6 | Importance of early diagnosis of pancreaticobiliary maljunction without biliary dilatation显示文摘AIM:To clarify the strategy for early diagnosis of pancreaticobiliary maljunction(PBM) without biliary dilatation and to pathologically examine gallbladder before cancer develops.METHODS:The anatomy of the union of the pancreatic and bile ducts was assessed by using endoscopic retrograde cholangiopancreatography(ERCP).Patients with a long common channel in which communication between the pancreatic and bile ducts was maintained even during sphincter contraction were diagnosed as having PBM.Of these,patients in which the maximal diameter of the bile duct was less than 10 mm were diagnosed with PBM without biliary dilatation.The process of diagnosing 54 patients with PBM without biliary dilatation was retrospectively investigated.Histopathological analysis of resected gallbladder specimens from 8 patients with PBM without biliary dilatation or cancer was conducted.RESULTS:Thirty-six PBM patients without biliary dilatation were diagnosed with gallbladder cancer after showing clinical symptoms such as abdominal or back pain(n = 16) or jaundice(n = 12).Radical surgery for gallbladder cancer was only possible in 11 patients(31%) and only 4 patients(11%) survived for 5 years.Eight patients were suspected as having PBM without biliary dilatation from the finding of gallbladder wall thickening on ultrasound and the diagnosis was confirmed by ERCP and/or magnetic resonance cholangiopancreatography(MRCP).The median age of these 8 patients was younger by a decade than PBM patients with gallbladder cancer.All 8 patients underwent prophylactic cholecystectomy and bile duct cancer has not occurred.Wall thickness and mucosal height of the 8 resected gallbladders were significantly greater than controls,and hyperplastic changes,hypertrophic muscular layer,subserosal fibrosis,and adenomyomatosis were detected in 7(88%),5(63%),7(88%) and 5(63%) patients,respectively.Ki-67 labeling index was high and K-ras mutation was detected in 3 of 6 patients.CONCLUSION:To detect PBM without biliary dilatation before onset of gallbladder cancer,we should perform MRCP for individuals showing increased gallbladder wall thickness on ultrasound. | Kensuke Takuma Terumi Kamisawa Taku Tabata Seiichi Hara Sawako Kuruma Yoshihiko Inaba Masanao Kurata Goro Honda Koji Tsuruta Shin-ichiro Horiguchi Yoshinori Igarashi | 2012 | World Journal of Gastroenterology2012，18，26： | 13 |
| 7 | E2FBP1 antagonizes the p16^(INK4A)-Rb tumor suppressor machinery for growth suppression and cellular senescence by regulating promyelocytic leukemia protein stability显示文摘Cellular senescence is an irreversible cell cycle arrest triggered by the activation of oncogenes or mitogenic signaling as well as the enforced expression of tumor suppressors such as p53, p16 INK4A and promyelocytic leukemia protein (PML) in normal cells. E2F-binding protein 1 (E2FBP1), a transcription regulator for E2F, induces PML reduction and suppresses the formation of PML-nuclear bodies, whereas the down-regulation of E2FBP1 provokes the PML-dependent premature senescence in human normal fibroblasts. Here we report that the depletion of E2FBP1 induces the accumulation of PML through the Ras-dependent activation of MAP kinase signaling. The cellular levels of p16 INK4A and p53 are elevated during premature senescence induced by depletion of E2FBP1, and the depletion of p16 INK4A , but not p53 rescued senescent cells from growth arrest. Therefore, the premature senescence induced by E2FBP1 depletion is achieved through the p16 INK4A -Rb pathway. Similar to human normal fibroblasts, the growth inhibition induced by E2FBP1 depletion is also observed in human tumor cells with intact p16 INK4A and Rb. These results suggest that E2FBP1 functions as a critical antagonist to the p16 INK4A -Rb tumor suppressor machinery by regulating PML stability. | Yayoi Fukuyo Akiko Takahashi Eiji Hara Nobuo Horikoshi Tej K.

| 8 | Liquid biopsy in patients with pancreatic cancer: Circulating tumor cells and cell-free nucleic acids显示文摘Despite recent advances in surgical techniques and perioperative management, the prognosis of pancreatic cancer(PCa) remains extremely poor. To provide optimal treatment for each patient with Pca, superior biomarkers are urgently needed in all phases of management from early detection to staging, treatment monitoring, and prognosis. In the blood of patients with cancer, circulating tumor cells(CTCs) and cell-free nucleic acids(cf NAs), such as DNA, m RNA, and noncoding RNA have been recognized. In the recent years, their presence in the blood has encouraged researchers to investigate their potential use as novel blood biomarkers, and numerous studies have demonstrated their potential clinical utility as a biomarker for certain types of cancer. This concept, called 'liquid biopsy' has been focused on as a less invasive, alternative approach to cancer tissue biopsy for obtaining genetic and epigenetic aberrations that contribute to oncogenesis and cancer progression. In this article, we review the available literature on CTCs and cfN As in patients with cancer, particularly focusing on PCa, and discuss future perspectives in this field. | Taisuke Imamura Shuhei Komatsu Daisuke Ichikawa Tsutomu Kawaguchi Mahito Miyamae Wataru Okajima Takuma Ohashi Tomohiro Arita Hirotaka Konishi Atsushi Shiozaki Ryo Morimura Hisashi Ikoma Kazuma Okamoto Eigo Otsuji | 2016 | World Journal of Gastroenterology2016，22，25： | 10 |
| 9 | Sclerosing cholangitis associated with autoimmune pancreatitis differs from primary sclerosing cholangitis显示文摘AIM:To clarify the characteristic features of biliary le-sions in patients with autoimmune pancreatitis(AIP) and compare them with those of primary sclerosing cholangitis(PSC) .METHODS:The clinicopathological characteristics of 34 patients with sclerosing cholangitis(SC) associated with AIP were compared with those of 4 patients with PSC.RESULTS:SC with AIP occurred predominantly in el-derly men.Obstructive jaundice was the most frequent initial symptom in SC with AIP.Only SC patients with AIP had elevated serum IgG4 levels,and sclerosing diseases were more frequent in these patients.SC pa-tients with AIP responded well to steroid therapy.Seg-mental stenosis of the lower bile duct was observed only in SC patients with AIP,but a beaded and pruned-tree appearance was detected only in PSC patients.Dense infi ltration of IgG4-positive plasma cells was de-tected in the bile duct wall and the periportal area,as well as in the pancreas,of SC patients with AIP.CONCLUSION:SC with AIP is distinctly different from PSC.The two diseases can be discriminated based on cholangiopancreatographic findings and serum IgG4 levels. | Terumi Kamisawa Kensuke Takuma Hajime Anjiki Naoto Egawa Masanao Kurata Goro Honda Kouji Tsuruta | 2009 | World Journal of Gastroenterology2009，15，19： | 9 |
| 10 | Oral esomeprazole vs injectable omeprazole for the prevention of hemorrhage after endoscopic submucosal dissection显示文摘AIM To evaluate the effectiveness of oral esomeprazole(EPZ) vs injectable omeprazole(OPZ) therapy to prevent hemorrhage after endoscopic submucosal dissection(ESD).METHODS A case-control study was conducted using a quasirandomized analysis with propensity score matching. A total of 258 patients were enrolled in this study. Patients were treated with either oral EPZ or injectable OPZ. The endpoint was the incidence of hemorrhage after ESD.RESULTS Data of 71 subjects treated with oral EPZ and 172 subjects treated with injectable OPZ were analyzed. Analysis of 65 matched samples revealed no difference in the incidence of hemorrhage after ESD between the oral EPZ and injectable OPZ groups(OR = 0.89, 95%CI:0.35-2.27, P ≥ 0.99).CONCLUSION We conclude that oral EPZ therapy is a useful alternative to injectable PPI therapy for the prevention of hemorrhage after ESD. | Takashi Uchiyama Takuma Higurashi Hitoshi Kuriyama Yoshinobu Kondo Yasuo Hata Atsushi Nakajima | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，10： | 8 |

| 12 | A prospective randomized trial of lafutidine vs rabeprazole on post-ESD gastric ulcers显示文摘AIM:To compare the effects of rabeprazole and lafutidine on post-endoscopic submucosal dissection(ESD) gastric ulcers.METHODS:Patients with gastric tumors indicated for ESD were prospectively studied.After ESD,all patients were treated with intravenous omeprazole for the first 3 d.Patients were then randomly assigned to oral lafutidine or rabeprazole.Ulcer size,ulcer size reduction rate,and ulcer stage were evaluated 4 wk later.Occurrence of complication was monitored throughout the 4-wk period.RESULTS:Sixty five patients were enrolled in the study,and 60 patients were subjected to the final analysis.In the lafutidine group(30 lesions in 29 patients),initial and 4-wk post-ESD ulcer sizes were 33.3 ± 9.2 and 10.5 ± 4.8 mm,respectively.In the rabeprazole group(34 lesions in 31 patients),the values were 34.7 ± 11.3 and 11.8 ± 6.7 mm,respectively.Ulcer size reduction rates in lafutidine and rabeprazole groups were 32.3% and 33.5%,respectively(P=0.974).Ulcer stage 4 wk post-ESD did not differ significantly between the two groups(P=0.868).Two cases in the rabeprazole group and no cases in the lafutidine group developed ulcer bleeding during the oral dose period,although the difference of bleeding rate between the two groups was not statistically significant(P=0.157).CONCLUSION:Lafutidine and rabeprazole have equivalent therapeutic effects on post-ESD gastric ulcers. | Tomohiko Richard Ohya Hiroki Endo Kei Kawagoe Tatsuro Yanagawa Katsuhiro Hanawa Ken Ohata Masako Asayama Kantaro Hisatomi Takuma Teratani Toshiaki Gunji Hajime Sato Nobuyuki Matsuhashi | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，1： | 7 |
| 13 | Endoscopic approach for diagnosing autoimmune pancreatitis显示文摘It is of utmost importance to differentiate autoimmune pancreatitis(AIP) from pancreatic cancer(PC).Segmental AIP cases are sometimes difficult to differentiate from PC.On endoscopic retrograde cholangio pancreatography,long or skipped irregular narrowing of the main pancreatic duct(MPD),less upstream dilatation of the distal MPD,side branches derived from the narrowed portion of the MPD,absence of obstruction of the MPD,and stenosis of the intrahepatic bile duct suggest AIP rather than PC.Abundant infiltration of IgG4-positive plasma cells is frequently and rather specifically detected in the major duodenal papilla of AIP patients.IgG4-immunostaining of biopsy specimens obtained from the major duodenal papilla is useful for supporting a diagnosis of AIP with pancreatic head involvement.On endoscopic ultrasonography(EUS),hyperechoic spots in the hypoechoic mass and the duct-penetrating sign suggest AIP rather than PC.EUS and intraductal ultrasonography sometimes show wall thickening of the common bile duct even in the segment in which abnormalities are not clearly observed with cholangiography in AIP patients.EUS-guided fine needle aspiration,especially EUS-guided Tru-Cut biopsy,is useful to diagnose AIP,as well as to exclude PC. | Terumi Kamisawa Hajime Anjiki Kensuku Takuma Naoto Egawa Takao Itoi Fumihide Itokawa | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，1： | 6 |
| 14 | Utility of pancreatography for diagnosing autoimmune pancreatitis显示文摘AIM: To identify pancreatographic findings that facilitate differentiating between autoimmune pancreatitis (AIP) and pancreatic cancer (PC) on endoscopic retrograde cholangiopancreatography (ERCP) and magnetic resonance cholangiopancreatography (MRCP). METHODS: ERCP findings of 48 AIP and 143 PC patients were compared. Diagnostic accuracies for AIP by ERCP and MRCP were compared in 30 AIP patients. RESULTS: The following ERCP findings suggested a diagnosis of AIP rather than PC. Obstruction of the main pancreatic duct (MPD) was more frequently detected in PC (P < 0.001). Skipped MPD lesions were detected only in AIP (P < 0.001). Side branch derivation from the narrowed MPD was more frequent in AIP (P < 0.001). The narrowed MPD was longer in AIP (P < 0.001), and a narrowed MPD longer than 3 cm was more frequent in AIP (P < 0.001). Maximal diameter of the upstream MPD was smaller in AIP (P < 0.001), and upstream dilatation of the MPD less than 5 mm was more frequent in AIP (P < 0.001). Stenosis of the lower bile duct was smooth in 87% of AIP and irregular in 65% of PC patients (P < 0.001). Stenosis of the intrahepatic or hilar bile duct was detected only in AIP (P = 0.001). On MRCP, diffuse narrowing of the MPD on ERCP was shown as a skipped non-visualized lesion in 50% and faint visualization in 19%, but segmental narrowing of the MPD was visualized faintly in only 14%. CONCLUSION: Several ERCP findings are useful for differentiating AIP from PC. Although MRCP cannot replace ERCP for the diagnostic evaluation of AIP, some MRCP findings support the diagnosis of AIP. | Kensuke Takuma Terumi Kamisawa Taku Tabata Yoshihiko Inaba Naoto Egawa Yoshinori Igarashi | 2011 | World Journal of Gastroenterology2011，17，18： | 6 |
| 15 | Differences between diffuse and focal autoimmune pancreatitis显示文摘AIM:To investigate differences in clinical features between diffuse-and focal-type autoimmune pancreatitis(AIP).METHODS:Based on radiological findings by computed tomography and/or magnetic resonance imaging,we divided 67 AIP patients into diffuse type(D type) and focal type(F type).We further divided F type into head type(H type) and body and/or tail type(B/T type) according to the location of enlargement.Finally,we classified the 67 AIP patients into three groups:D type,H type and B/T type.We compared the three types of AIP in terms of clinical,laboratory,radiological,functional and histological findings and clinical course.RESULTS:There were 34 patients with D-type,19 with H-type and 14 with B/T-type AIP.Although obstructive jaundice was frequently detected in D-typepatients(88%) and H-type patients(68%),no B/T-type patients showed jaundice as an initial symptom(P < 0.001).There were no differences in frequency of abdominal pain,but acute pancreatitis was associated more frequently in B/T-type patients(36%) than in D-type patients(3%)(P = 0.017).Serum immunoglobulin G(IgG)4 levels were significantly higher in D-type patients(median 309 mg/dL) than in B/T-type patients(133.5 mg/dL)(P = 0.042).Serum amylase levels in B/T-type patients(median:114 IU/L) were significantly greater than in H-type patients(72 IU/L)(P = 0.049).Lymphoplasmacytic sclerosing pancreatitis(LPSP) was histologically confirmed in 6 D-type,7 H-type and 4 B/T-type patients;idiopathic duct-centric pancreatitis was observed in no patients.Marked fibrosis and abundant infiltration of CD20-positive B lymphocytes with few IgG4-positive plasma cells were detected in 2 B/T-type patients.Steroid therapy was effective in all 50 patients(31 D type,13 H type and 6 B/T type).Although AIP relapsed during tapering or after stopping steroids in 3 D-type and 3 H-type patients,no patients relapsed in B/T type.During follow-up,radiological features of 6 B/T-type patients were not changed and 1 B/T-type patient improved naturally.CONCLUSION:Clinical features of H-type AIP were similar to those of D-type,but B/T-type differed from D and H types.B/T-type may involve diseases other than LPSP. | Taku Tabata Terumi Kamisawa Kensuke Takuma Seiichi Hara Sawako Kuruma Yoshihiko Inaba | 2012 | World Journal of Gastroenterology2012，18，17： | 6 |

| 17 | Secondary-Atom-Doping Enables Robust Fe-N-C Single-Atom Catalysts with Enhanced Oxygen Reduction Reaction显示文摘Single-atom catalysts(SACs) with nitrogen-coordinated nonprecious metal sites have exhibited inimitable advantages in electrocatalysis.However,a large room for improving their activity and durability remains.Herein,we construct atomically dispersed Fe sites in N-doped carbon supports by secondary-atom-doped strategy.Upon the secondary doping,the density and coordination environment of active sites can be efficiently tuned,enabling the simultaneous improvement in the number and reactivity of the active site.Besides,structure optimizations in terms of the enlarged surface area and improved hydrophilicity can be achieved simultaneously.Due to the beneficial microstructure and abundant highly active FeN_5 moieties resulting from the secondary doping,the resultant catalyst exhibits an admirable half-wave potential of 0.81 V versus 0.83 V for Pt/C and much better stability than Pt/C in acidic media.This work would offer a general strategy for the design and preparation of highly active SACs for electrochemical energy devices. | Xin Luo Xiaoqian Wei Hengjia Wang Wenling Gu Takuma Kaneko Yusuke Yoshida Xiao Zhao Chengzhou Zhu | 2020 | Nano-Micro Letters2020，12，11： | 5 |
| 18 | Stability of cirrhotic systemic hemodynamics ensures sufficient splanchnic blood flow after living-donor liver transplantation in adult recipients with liver cirrhosis显示文摘AIM: To investigate the correlation between systemic hemodynamics and splanchnic circulation in recipients with cirrhosis undergoing living-donor liver transplantation (LDLT), and to clarify how systemic hemodynamics impact on local graft circulation after LDLT. METHODS: Systemic hemodynamics, indocyanine green (ICG) elimination rate (KICG) and splanchnic circulation were simultaneously and non-invasively investigated by pulse dye densitometry (PDD) and ultrasound. Accurate estimators of optimal systemic hyperdynamics after LDLT [i.e., balance of cardiac output (CO) to blood volume (BV) and mean transit time (MTT), defined as the timerequired for half the administered ICG to pass through an attached PDD sensor in the first circulation] were also measured. Thirty recipients with cirrhosis were divided into two groups based on clinical outcomes corresponding to postoperative graft function. RESULTS: Cirrhotic systemic hyperdynamics characterized by high CO, expanded BV and low total peripheral resistance (TPR) were observed before LDLT. TPR reflecting cirrhotic vascular alterations was slowly restored after LDLT in both groups. Although no significant temporal differences in TPR were detected between the two groups, CO/BV and MTT differed significantly. Recipients with good outcomes showed persistent cirrhotic systemic hyperdynamics after LDLT, whereas recipients with poor outcomes presented with unstable cirrhotic systemic hyperdynamics and severely decreased KICG. Systemic hyperdynamic disorders after LDLT impacted on portal venous flow but not hepatic arterial flow. CONCLUSION: We conclude that subtle systemic hyperdynamics disorders impact on splanchnic circulation, and that an imbalance between CO and BV decreases portal venous flow, which results in critical outcomes. | Tomohide Hori Shintaro Yagi Taku Iida Kentaro Taniguchi Kentaro Yamagiwa Chiduru Yamamoto Takashi Hasegawa Koichiro Yamakado Takuma Kato Kanako Saito Linan Wang Mie Torii Yukinobu Hori Kan Takeda Kazuo Maruyama Shinji Uemoto | 2007 | World Journal of Gastroenterology2007，13，44： | 5 |
| 19 | Prophylactic lateral pelvic lymph node dissection in stage Ⅳ low rectal cancer显示文摘AIM To assess the clinical significance of prophylactic lateral pelvic lymph node dissection (LPLND) in stage Ⅳ low rectal cancer.METHODS We selected 71 consecutive stage Ⅳ low rectal cancer patients who underwent primary tumor resection,and enrolled 50 of these 71 patients without clinical LPLN metastasis.The patients had distant metastasis such as liver,lung,peritoneum,and paraaortic LN.Clinical LPLN metastasis was defined as LN with a maximum diameter of 10 mm or more on preoperative pelvic computed tomography scan.All patients underwent primary tumor resection,27 patients underwent total mesorectal excision(TME) with LPLND(LPLND group),and 23 patients underwent only TME(TME group).Bilateral LPLND was performed simultaneously with primary tumor resection in LPLND group.R0 resection of both primary and metastatic sites was achieved in 20 of 50 patients.We evaluated possible prognostic factors for 5-year overall survival (OS),and compared 5-year cumulative local recurrence between the LPLND and TME groups.RESULTS For OS,univariate analyses revealed no significant benefit in the LPLND compared with the TME group (28.7% vs 17.0%,P = 0.523); multivariate analysis revealed that R0 resection was an independent prognostic factor.Regarding cumulative local recurrence,the LPLND group showed no significant benefit compared with TME group (21.4% vs 14.8%,P = 0.833).CONCLUSION Prophylactic LPLND shows no oncological benefits in patients with Stage Ⅳ low rectal cancer without clinical LPLN metastasis. | Hiroshi Tamura Yoshifumi Shimada Hitoshi Kameyama Ryoma Yagi Yosuke Tajima Takuma Okamura Mae Nakano Masato Nakano Masayuki Nagahashi Jun Sakata Takashi Kobayashi Shin-ichi Kosugi Hitoshi Nogami Satoshi Maruyama Yasumasa Takii Toshifumi Wakai | 2017 | World Journal of Clinical Oncology2017，8，5： | 4 |
