1Review of the diagnosis and management of gastrointestinal bezoars显示文摘The formation of a bezoar is a relatively infrequentdisorder that affects the gastrointestinal system.Bezoars are mainly classified into four types dependingon the material constituting the indigestible mass of thebezoar phytobezoars, trichobezoars, pharmacobezoars,and lactobezoars. Gastric bezoars often cause ulcerativelesions in the stomach and subsequent bleeding,whereas small intestinal bezoars present with smallbowel obstruction and ileus. A number of articles haveemphasized the usefulness of Coca-Cola? administrationfor the dissolution of phytobezoars. However, persimmonphytobezoars may be resistant to such dissolutiontreatment because of their harder consistency comparedto other types of phytobezoars. Better understanding ofthe etiology and epidemiology of each type of bezoarwill facilitate prompt diagnosis and management.Here we provide an overview of the prevalence, classification,predisposing factors, and manifestations ofbezoars. Diagnosis and management strategies arealso discussed, reviewing mainly our own case series.Recent progress in basic research regarding persimmonphytobezoars is also briefly reviewed.Masaya Iwamuro Hiroyuki Okada Kazuhiro Matsueda Tomoki Inaba Chiaki Kusumoto Atsushi Imagawa Kazuhide Yamamoto 2015World Journal of Gastrointestinal Endoscopy2015,7,4:22
2Strategy 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 2012World Journal of Gastroenterology2012,18,10:20
3Importance 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 2012World Journal of Gastroenterology2012,18,26:13
4Minimally invasive surgery for upper gastrointestinal cancer: Our experience and review of the literature显示文摘Minimally invasive surgery(MIS) for upper gastro-intestinal(GI) cancer, characterized by minimal access, has been increasingly performed worldwide. It not only results in better cosmetic outcomes, but also reduces intraoperative blood loss and postoperative pain, leading to faster recovery; however, endoscopically enhanced anatomy and improved hemostasis via positive intracorporeal pressure generated by CO2 insufflation have not contributed to reduction in early postoperative complications or improvement in long-term outcomes. Since 1995, we have been actively using MIS for operable patients with resectable upper GI cancer and have developed stable and robust methodology in conducting totally laparoscopic gastrectomy for advanced gastric cancer and prone thoracoscopic esophagectomy for esophageal cancer using novel technology including da Vinci Surgical System(DVSS). We have recently demonstrated that use of DVSS might reduce postoperative local complications including pancreatic fistula after gastrectomy and recurrent laryngeal nerve palsy after esophagectomy. In this article, we present the current status and future perspectives on MIS for gastric and esophageal cancer based on our experience and a review of the literature.Koichi Suda Masaya Nakauchi Kazuki Inaba Yoshinori Ishida Ichiro Uyama 2016World Journal of Gastroenterology2016,22,19:13
5Advances in laparoscopy for acute care surgery and trauma显示文摘The greatest advantages of laparoscopy when compared to open surgery include the faster recovery times, shorter hospital stays, decreased postoperative pain, earlier return to work and resumption of normal daily activity as well as cosmetic benefits. Laparoscopy today is considered the gold standard of care in the treatment of cholecystitis and appendicitis worldwide. Laparoscopy has even been adopted in colorectal surgery with good results. The technological improvements in this surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its utilization in operations with fully intracorporeal anastomoses. Further progress in laparoscopy has included single-incision laparoscopic surgery and natural orifice trans-luminal endoscopic surgery. Nevertheless, laparoscopy for emergency surgery is still considered challenging and is usually not recommended due to the lack of adequate experience in this area. The technical difficulties of operating in the presence of diffuse peritonitis or large purulent collections and diffuse adhesions are also given as reasons. However, the potential advantages of laparoscopy, both in terms of diagnosis and therapy, are clear. Major advantages may be observed in cases with diffuse peritonitis secondary to perforated peptic ulcers,for example, where laparoscopy allows the confirmation of the diagnosis, the identification of the position of the ulcer and a laparoscopic repair with effective peritoneal washout. Laparoscopy has also revolutionized the approach to complicated diverticulitis even when intestinal perforation is present. Many other emergency conditions can be effectively managed laparoscopically, including trauma in select hemodynamically-stable patients. We have therefore reviewed the most recent scientific literature on advances in laparoscopy for acute care surgery and trauma in order to demonstrate the current indications and outcomes associated with a laparoscopic approach to the treatment of the most common emergency surgical conditions.Matteo Mandrioli Kenji Inaba Alice Piccinini Andrea Biscardi Massimo Sartelli Ferdinando Agresta Fausto Catena Roberto Cirocchi Elio Jovine Gregorio Tugnoli Salomone Di Saverio 2016World Journal of Gastroenterology2016,22,2:11
6Non-robotic minimally invasive gastrectomy as an independent risk factor for postoperative intra-abdominal infectious complications: A single-center, retrospective and propensity score-matched analysis显示文摘BACKGROUND Minimally invasive surgery for gastric cancer(GC) has gained widespread use as a safe curative procedure especially for early GC.AIM To determine risk factors for postoperative complications after minimally invasive gastrectomy for GC.METHODS Between January 2009 and June 2019, 1716 consecutive patients were referred to our division for primary GC. Among them, 1401 patients who were diagnosed with both clinical and pathological Stage Ⅲ or lower GC and underwent robotic gastrectomy(RG) or laparoscopic gastrectomy(LG) were enrolled. Retrospective chart review and multivariate analysis were performed for identifying risk factors for postoperative morbidity.RESULTS Morbidity following minimally invasive gastrectomy was observed in 7.5% of the patients. Multivariate analyses demonstrated that non-robotic minimally invasive surgery, male gender, and an operative time of ≥ 360 min were significant independent risk factors for morbidity. Therefore, morbidity was compared between RG and LG. Accordingly, propensity-matched cohort analysis revealed that the RG group had significantly fewer intra-abdominal infectious complications than the LG group(2.5% vs 5.9%, respectively;P = 0.038), while no significant differences were noted for other local or systemic complications.Multivariate analyses of the propensity-matched cohort revealed that non-robotic minimally invasive surgery [odds ratio = 2.463(1.070–5.682);P = 0.034] was a significant independent risk factor for intra-abdominal infectious complications.CONCLUSION The findings showed that robotic surgery might improve short-term outcomes following minimally invasive radical gastrectomy by reducing intra-abdominal infectious complications.Susumu Shibasaki Koichi Suda Masaya Nakauchi Kenichi Nakamura Kenji Kikuchi Kazuki Inaba Ichiro Uyama 2020World Journal of Gastroenterology2020,26,11:8

9Expression of Angiopoietin-1, 2 and 4 and Tie-1 and 2 in gastrointestinal stromal tumor, leiomyoma and schwannoma显示文摘AIM: To investigate the role of angiopoietin (Ang) -1, -2 and -4 and its receptors, Tie-1 and -2, in the growth and differentiation of gastrointestinal stromal tumors (GISTs).METHODS: Thirty GISTs, seventeen leiomyomas and six schwannomas were examined by immunohistochemistry in this study.RESULTS: Ang-1, -2 and -4 proteins were expressed in the cytoplasm of tumor cells, and Tie-1 and -2 were expressed both in the cytoplasm and on the membrane of all tumors. Immunohistochemical staining revealed that 66.7% of GISTs (20 of 30), 76.5% of leiomyomas (13 of 17) and 83.3% of schwannomas (5 of 6) were positive for Ang-1. 83.3% of GISTs (25 of 30), 82.4% of leiomyomas (14 of 17) and 100% of schwannomas (6 of 6) were positive for Ang-2. 36.7% of GISTs (11 of 30), 58.8% of leiomyomas (10 of 17) and 83.3% of schwannomas (5 of 6) were positive for Ang-4. 60.0% of GISTs (18 of 30), 82.4% of leiomyomas and 100% of schwannomas (6 of 6) were positive for Tie-1. 10.0% of GISTs (3 of 30), 94.1% of leiomyomas (16 of 17) and 33.3% of schwannomas (2 of 6) were positive for Tie-2. Tie-2 expression was statistically different between GISTs and leiomyomas (P < 0.001). However, there was no correlation between expression of angiopoietin pathway components and clinical risk categories.CONCLUSION: Our results suggest that the angiopoietin pathway plays an important role in the differentiation of GISTs, leiomyomas and schwannomas.Toshiyuki Nakayama Maki Inaba Shinji Naito Yumi Mihara Shiro Miura Mitsuru Taba Ayumi Yoshizaki Chun-Yang Wen Ichiro Sekine 2007World Journal of Gastroenterology2007,13,33:6
10Utility 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 2011World Journal of Gastroenterology2011,17,18:6
11Differences 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 2012World Journal of Gastroenterology2012,18,17:6

13Bone Density and Mechanical Properties in Femoral Bone of Swim Loaded Aged Mice显示文摘Effects of swirnming on bone density and mechanical properties of femur were investigated in aged male and female mice. R/1 strain of senescence accelerated mouse (SAM) at eleven months old was used. Two groups of males and two groups of females each consisting of 7 mice were used. One male and one female groups were loaded with a swim regiment of 40 min a day, 5 days a week for 6 consecutive weeks. The remaining groups were used as the controls. All mice were fed with the standard diet and water ad libitum during the experiments.The results of this study indicated that (i) the hady weight was significantly (P<0.05) lower in the swimming groups than in the control groups in boh sexes. (ii) The bone density was significantly higher (P <0.05) in the swimming groups than in the control groups in boh sexes. However, there was no sighficant difference in cortical thickness index. (iii) In the mechanical properties of bone, there were no significant differences in the level of the maximum breaking force, the ultimate stress and the deformation between the swimndng and the contro groups in beth sexes. However, the elasticity of the bone of the female hoce in the swimming group was significantly higher (P<0.05) than that of the control group.These results suggest that regimented swimming for the aged mice might suppress age-associated bone loss, and the effect of exercise in the females is greater that in the males.AKIO HOSHI HIROMI WATANABE MOMOKO CHIBA AND YUTAKA INABA (Department of Health and Physical Education, Nippon Dental University, 1-8-2 Fu-jimi, Chiyoda-ku, Tokyo, Japan )(Department of Health and Physical Education, Nippon Dental University, Fugimi, T 1998Biomedical and Environmental Sciences1998,11,3:4

15未来货币政策的构建:政策工具选择显示文摘全球金融危机爆发后,很多OECD经济体设立了新型货币政策工具。未来的经济环境与危机时期相比有诸多不同,与危机前相比更宽泛的金融稳定概念已成为货币政策重要目标,本文分析了未来哪些货币政策新工具需要保留,并分析了在向常态化经济转型过渡期间可以选择哪些货币政策新工具,以及如果经济陷入长期停滞又该如何选择这些工具。在后复苏时期,央行可以回归到盯住短期市场利率和缩小资产负债表。然而,新的流动性监管要求可能需要货币政策实施有所改变。向常态化经济转型过渡会是一个漫长的过程,需要组合使用各种流动性工具。同时,央行可以采用利率走廊下限体系,维护金融稳定。作为降低政策利率的替代品,非传统货币政策措施必要性降低,除非经济陷入长期停滞。在后复苏时期,仍然可以延续扩大抵押品和交易对方范围,推广央行间货币互换。Kei-Ichiro Inaba Rory O'Farrell ?ukasz Rawdanowicz Ane Kathrine Christensen 盖新哲 朱尘 2016国际金融研究2016,,3:4

18Factors associated with complicated erosive esophagitis: A Japanese multicenter, prospective, cross-sectional study显示文摘AIM To assess the clinical characteristics of patients with complicated erosive esophagitis(EE) and their associated factors.METHODS This prospective, cross-sectional study included patients diagnosed with EE by upper gastrointestinal endoscopy between October 2014 and March 2015 at 106 Japanese hospitals. Data on medical history, general condition, gastrointestinal symptoms, lifestyle habits, comorbidities, and endoscopic findings were collected using a standard form to create a dedicated database. Logistic regression analysis was used to calculate adjusted odds ratios(aO R) and 95%CI for the association with complicated EE.RESULTS During the study period, 1749 patients diagnosed with EE, 38.3% of whom were prescribed proton pump inhibitors(PPIs) were included. Of them, 143(8.2%) had EE complications. Esophageal bleeding occurred in 84(4.8%) patients, esophageal strictures in 45(2.6%) patients, and 14(0.8%) patients experienced both. Multivariate analysis showed that increased age(a OR: 1.05; 95%CI: 1.03-1.08), concomitant use of psychotropic agents(a OR: 6.51; 95%CI: 3.01-13.61), and Los Angeles grades B(a OR: 2.69; 95%CI: 1.48-4.96), C(aO R: 15.38; 95%CI: 8.62-28.37), and D(aO R: 71.49; 95%CI: 37.47-142.01) were significantly associated with complications, whereas alcohol consumption 2-4 d/wk was negatively associated(a OR: 0.23; 95%CI: 0.06-0.61). Analyzing associated factors with each EE complication separately showed esophageal ulcer bleeding were associated with increased age(a OR: 1.05; 95%CI: 1.02-1.07) and Los Angeles grades B(aO R: 3.60; 95%CI: 1.52-8.50), C(a OR: 27.61; 95%CI: 12.34-61.80), and D(a OR: 119.09; 95%CI: 51.15-277.29), while esophageal strictures were associated with increased age(a OR: 1.07; 95%CI: 1.04-1.10), gastroesophageal reflux symptom(aO R: 2.51; 95%CI: 1.39-4.51), concomitantuse of psychotropic agents(a OR: 11.79; 95%CI: 5.06-27.48), Los Angeles grades C(aO R: 7.35; 95%CI: 3.32-16.25), and D(a OR: 20.34; 95%CI: 8.36-49.53) and long-segment Barrett's esophagus(a OR: 4.63; 95%CI: 1.64-13.05).CONCLUSION Aging and severe EE were common associated factors, although there were more associated factors in esophageal strictures than esophageal ulcer bleeding. Despite the availability and widespread use of PPIs, EE complications are likely to remain a problem in Japan owing to the aging population and high-stress society.Masahiro Sakaguchi Noriaki Manabe Nobuo Ueki Jun Miwa Tomoki Inaba Norimasa Yoshida Kouichi Sakurai Masahiro Nakagawa Hajime Yamada Michiya Saito Koji Nakada Katsuhiko Iwakiri Takashi Joh Ken Haruma 2017World Journal of Gastroenterology2017,23,2:3

20Laparoscopic repair of hiatal hernia with mesenterioaxial volvulus of the stomach显示文摘Although mesenterioaxial gastric volvulus is an uncommon entity characterized by rotation at the transverse axis of the stomach, laparoscopic repair procedures have still been controversial. We reported a case of mesenterioaxial intrathoracic gastric volvulus, which was successfully treated with laparoscopic repair of the diaphragmatic hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication. A 70-year-old Japanese woman was admitted to our hospital because of sudden onset of upper abdominal pain. An upper gastrointestinal series revealed an incarcerated intrathoracic mesenterioaxial volvulus of the distal portion of the stomach and the duodenum. The complete laparoscopic approach was used to repair the volvulus. The laparoscopic procedures involved the repair of the hiatal hernia using polytetrafluoroethylene mesh and Toupet fundoplication. This case highlights the feasibility and effectiveness of the laparoscopic procedure, and laparoscopic repair of the hiatal defect using a polytetrafluoroethylene mesh associated with Toupet fundoplication may be useful for preventing postoperative recurrence of hiatal her-nia, volvulus, and gastroesophageal reflux.Kazuki Inaba Yoichi Sakurai Jun Isogaki Yoshiyuki Komori Ichiro Uyama 2011World Journal of Gastroenterology2011,17,15:3
