| 1 | Criteria for the diagnosis and severity stratification of acute pancreatitis显示文摘Recent diagnostic and therapeutic progress for severe acute pancreatitis(SAP)remarkably decreased the casemortality rate.To further decrease the mortality rate of SAP,it is important to precisely evaluate the severity at an early stage,and initiate appropriate treatment as early as possible.Research Committee of Intractable Diseases of the Pancreas in Japan developed simpler criteria combining routinely available data with clinical signs.Severity can be evaluated by laboratory examinations or by clinical signs,reducing the defect values of the severity factors.Moreover,the severity criteria considered laboratory/clinical severity scores and contrastenhanced computed tomography(CE-CT)findings as independent risk factors.Thus,CE-CT scans are not necessarily required to evaluate the severity of acute pancreatitis.There was no fatal case in mild AP diagnosed by the CE-CT severity score,whereas case-mortality rate in those with SAP was 14.8%.Case-mortality of SAP that fulfilled both the laboratory/clinical and the CE-CT severity criteria was 30.8%.It is recommended,therefore,to perform CE-CT examination to clarify the prognosis in those patients who were diagnosed as SAP by laboratory/clinical severity criteria.Because the mortality rate of these patients with SAP is high,such patients should be transferred to advanced medical units. | Makoto Otsuki Kazunori Takeda Seiki Matsuno Yasuyuki Kihara Masaru Koizumi Masahiko Hirota Tetsuhide Ito Keisho Kataoka Motoji Kitagawa Kazuo Inui Yoshifumi Takeyama | 2013 | World Journal of Gastroenterology2013，19，35： | 24 |
| 2 | Current status of endoscopic retrograde cholangiopancreatography in patients with surgically altered anatomy显示文摘Endoscopic retrograde cholangiopancreatography(ERCP)in patients with surgically altered anatomy must be performed by a highly experienced endoscopist.The challenges are accessing the afferent limb in different types of reconstruction,cannulating a papilla with a reverse orientation,and performing therapeutic interventions with uncommon endoscopic accessories.The development of endoscopic techniques has led to higher success rates in this group of patients.Device-assisted ERCP is the endoscopic procedure of choice for high success rates in short-limb reconstruction;however,these success rate is lower in long-limb reconstruction.ERCP assisted by endoscopic ultrasonography is now popular because it can be performed independent of the limb length;however,it must be performed by a highly experienced and skilled endoscopist.Stent deployment and small stone removal can be performed immediately after ERCP assisted by endoscopic ultrasonography,but the second session is needed for other difficult procedures such as cholangioscopy-guided electrohydraulic lithotripsy.Laparoscopic-assisted ERCP has an almost 100%success rate in longlimb reconstruction because of the use of a conventional side-view duodenoscope,which is compatible with standard accessories.This requires cooperation between the surgeon and endoscopist and is suitable in urgent situations requiring concomitant cholecystectomy.This review focuses on the advantages,disadvantages,and outcomes of various procedures that are suitable in different situations and reconstruction types.Emerging new techniques and their outcomes are also discussed. | Chonlada Krutsri Mitsuhiro Kida Hiroshi Yamauchi Tomohisa Iwai Hiroshi Imaizumi Wasaburo Koizumi | 2019 | World Journal of Gastroenterology2019，25，26： | 23 |
| 3 | Immunoglobulin G4-related gastrointestinal diseases, are they immunoglobulin G4-related diseases?显示文摘In immunoglobulin G4(IgG4)-related disease(RD),organ enlargement or nodular lesions consisting of abundant infiltration of lymphocytes and IgG4-positive plasma cells and fibrosis are seen in various organs.Although infiltration of many IgG4-positive plasma cells is detected in the gastric and colonic mucosa and major duodenal papilla of patients with autoimmune pancreatitis,it cannot be diagnosed as a gastrointestinal lesion involved in IgG4-RD,because none of the following is observed in these lesions:a mass-like formation;dense fibrosis;or obliterative phlebitis.Based on our review of the literature,there appear to be two types of IgG4-related gastrointestinal disease.One is a gastrointestinal lesion showing marked thickening of the wall of the esophagus and stomach,consisting of dense fibrosis with abundant infiltration of IgG4-positive plasma cells,which usually show submucosal spreading.The other is an IgG4-related pseudotumor occurring in gastrointestinal regions such as the stomach,colon,and major duodenal papilla,showing polypoid or mass-like lesions.Most solitary IgG4-related gastrointestinal lesions that are not associated with other IgG4-RD appear to be difficult to diagnose.It is of utmost importance to rule out malignancy.However,these lesions may respond to steroid therapy.To avoid unnecessary resection,IgG4-related gastrointestinal diseases should be considered in the differential diagnosis. | Satomi Koizumi Terumi Kamisawa Sawako Kuruma Taku Tabata Kazuro Chiba Susumu Iwasaki Yuka Endo Go Kuwata Koichi Koizumi Tooru Shimosegawa Kazuichi Okazaki Tsutomu Chiba | 2013 | World Journal of Gastroenterology2013，19，35： | 12 |

| 5 | Condyloma acuminatum of the anal canal,treated with endoscopic submucosal dissection显示文摘Condyloma acuminatum(CA) is a common sexually transmitted disease caused by human papilloma virus infection. Not all individuals develop persistent, progressive disease, but careful follow up is required with moderate-to-severe dysplasia to prevent progression to malignancy. Standard therapies include surgical treatments(trans-anal resection and transanal endoscopic microsurgery) and immunotherapeutic and topical methods(topical imiquimod); however, local recurrence remains a considerable problem. Here, we report a case with superficial CA of the anal canal, treated with endoscopic submucosal dissection(ESD). A 28-year-old man presented with a chief complaint of hematochezia. Digital exam did not detect a tumor. Screening colonoscopy revealed 10-mm long, whitish condyles extending from the anal canal to the lower rectum. The lesion covered almost the whole circumference, and only a small amount of normal mucosa remained. Magnifying endoscopy with narrow band imaging showed brownish hairpin-shaped, coiled capillaries. Although histopathological diagnosis by biopsy revealed CA, accurate histological differentiation between CA, papilloma, and squamous cell carcinoma can be difficult with a small specimen. Therefore, weperformed diagnostic ESD, which provides a complete specimen for precise histopathological evaluation. The pathological diagnosis was CA, with moderate dysplasia(anal intraepithelial neoplasia 2). There was no recurrence at 16 mo after the initial ESD. Compared to surgical treatment, endoscopic diagnosis and resection could be performed simultaneously and the tumor margin observed clearly with a magnifying chromocolonoscopy, resulting in less recurrence. These findings suggest that endoscopic resection may be an alternative method for CA that prevents recurrence. | Akiko Sasaki Takeshi Nakajima Hideto Egashira Kotaro Takeda Shinnosuke Tokoro Chikamasa Ichita Sakue Masuda Haruki Uojima Kazuya Koizumi Takeshi Kinbara Taku Sakamoto Yutaka Saito Makoto Kako | 2016 | World Journal of Gastroenterology2016，22，8： | 11 |
| 6 | DOG1 is useful for diagnosis of KIT-negative gastrointestinal stromal tumor of stomach显示文摘Approximately 80%-95%of gastrointestinal stromal tumors(GISTs)show positive staining for KIT,while the other 5%-20%show negative staining.If the tumor is negative for KIT,but is positive for CD34,a histological diagnosis is possible.However,if the tumor is negative for KIT,CD34,S-100,and SMA,a definitive diagnosis is often challenging.Recently,Discovered on GIST-1(DOG1)has received considerable attention as a useful molecule for the diagnosis of GIST.DOG1,a membrane channel protein,is known to be overexpressed in GIST.Because the sensitivity and specificity of DOG1 are higher than those of KIT,positive staining for DOG1has been reported,even in KIT-negative GISTs.KITnegative GISTs most commonly arise in the stomach and are mainly characterized by epithelioid features histologically.We describe our experience with a rare case of a KIT-negative GIST of the stomach that was diagnosed by positive immunohistochemical staining for DOG1 in a patient who presented with severe anemia.Our findings suggest that immunohistochemical staining for DOG1,in addition to gene analysis,is useful for the diagnosis of KIT-negative tumors that are suspected to be GISTs. | Takuya Wada Satoshi Tanabe Kenji Ishido Katsuhiko Higuchi Tohru Sasaki Chikatoshi Katada Mizutomo Azuma Akira Naruke Myunguchul Kim Wasaburo Koizumi Tetsuo Mikami | 2013 | World Journal of Gastroenterology2013，19，47： | 11 |
| 7 | Short-type single balloon enteroscope for endoscopic retrograde cholangiopancreatography with altered gastrointestinal anatomy显示文摘AIM:To evaluate the effectiveness of a short-type single-balloon-enteroscope(SBE) for endoscopic retrograde cholangiopancreatography(ERCP) in patients with a reconstructed intestine.METHODS:Short-type SBE was developed to perform ERCP in postoperative patients with a reconstructed intestine.Short-type SBE is a direct-viewing endoscope with the following specifications:working length,1520 mm;total length,1840 mm;channel diameter,3.2 mm.In addition,short-type SBE has a water-jet channel.The study group comprised 22 patients who underwent 31 sessions of short-type SBE-assisted ERCP from June 2011 through May 2012.Reconstruction was performed by Billroth-Ⅱ(B-Ⅱ) gastrectomy in 6 patients(8 sessions),Roux-en-Y(R-Y) gastrectomy in 14 patients(21 sessions),and R-Y hepaticojejunostomy in 2 patients(2 sessions).We retrospectively studied the rate of reaching the blind end(papilla of Vater or choledochojejunal anastomosis),mean time required to reach the blind end,diagnostic success rate(defined as the rate of successfully imaging the bile and pancreatic ducts),therapeutic success rate(defined as the rate of successfully completing endoscopic treatment),mean procedure time,and complications.RESULTS:Among the 31 sessions of ERCP,the rate of reaching the blind end was 88% in B-Ⅱ gastrectomy,91% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.The mean time required to reach the papilla was 18.3 min in B-Ⅱ gastrectomy,21.1 min in R-Y gastrectomy,and 32.5 min in R-Y hepaticojejunostomy.The diagnostic success rates in all patients and those with an intact papilla were respectively 86% and 86% in B-Ⅱ gastrectomy,90% and 87% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.The therapeutic success rates in all patients and those with an intact papilla were respectively 100% and 100% in B-Ⅱ gastrectomy,94% and 92% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.Because the channel diameter was 3.2 mm,stone extraction could be performed with a wire-guided basket in 12 sessions,and wireguided intraductal ultrasonography could be performed in 8 sessions.As for complications,hyperamylasemia(defined as a rise in serum amylase levels to more than 3 times the upper limit of normal) occurred in 1 patient(7 sessions) with a B-Ⅱ gastrectomy and 4 patients(19 sessions) with an R-Y gastrectomy.After ERCP in patients with an R-Y gastrectomy,2 patients(19 sessions) had pancreatitis,1 patient(21 sessions) had gastrointestinal perforation,and 1 patient(19 sessions) had papillary bleeding.Pancreatitis and bleeding were both mild.Gastrointestinal perforation improved after conservative treatment.CONCLUSION:Short-type SBE is effective for ERCP in patients with a reconstructed intestine and allows most conventional ERCP devices to be used. | Hiroshi Yamauchi Mitsuhiro Kida Kosuke Okuwaki Shiro Miyazawa Tomohisa Iwai Miyoko Takezawa Hidehiko Kikuchi Maya Watanabe Hiroshi Imaizumi Wasaburo Koizumi | 2013 | World Journal of Gastroenterology2013，19，11： | 10 |
| 8 | Innovations and techniques for balloon-enteroscopeassisted endoscopic retrograde cholangiopancreatography in patients with altered gastrointestinal anatomy显示文摘Endoscopic retrograde cholangiopancreatography(ERCP) remains challenging in patients who have undergone surgical reconstruction of the intestine.Recently,many studies have reported that balloonenteroscope-assisted ERCP(BEA-ERCP) is a safe and effective procedure.However,further improvements in outcomes and the development of simplified procedures are required.Percutaneous treatment,Laparoscopy-assisted ERCP,endoscopic ultrasoundguided anterograde intervention,and open surgery are effective treatments.However,treatment should be noninvasive,effective,and safe.We believe that these procedures should be performed only in difficult-to-treat patients because of many potential complications.BEA-ERCP still requires high expertiselevel techniques and is far from a routinely performed procedure.Various techniques have been proposed to facilitate scope insertion(insertion with percutaneous transhepatic biliary drainage(PTBD) rendezvous technique,Short type single-balloon enteroscopes with passive bending section,Intraluminal injection of indigo carmine,CO2 inflation guidance),cannulation(PTBD or percutaneous transgallbladder drainage rendezvous technique,Dilation using screw drill,Rendezvous technique combining DBE with a cholangioscope,endoscopic ultrasound-guided rendezvous technique),and treatment(overtube-assisted technique,Short type balloon enteroscopes) during BEA-ERCP.The use of these techniques may allow treatment to be performed by BEA-ERCP in many patients.A standard procedure for ERCP yet to be established for patients with a reconstructed intestine.At present,BEA-ERCP is considered the safest and most effective procedure and is therefore likely to be recommended as firstline treatment.In this article,we discuss the current status of BEA-ERCP in patients with surgically altered gastrointestinal anatomy. | Hiroshi Yamauchi Mitsuhiro Kida Hiroshi Imaizumi Kosuke Okuwaki Shiro Miyazawa Tomohisa Iwai Wasaburo Koizumi | 2015 | World Journal of Gastroenterology2015，21，21： | 9 |

| 10 | Recent advances in photodynamic diagnosis of gastriccancer using 5-aminolevulinic acid显示文摘Photodynamic diagnosis based on 5-aminolevulinic acidinduced protoporphyrin IX has been clinically applied in many fields based upon its evidenced efficacy and adequate safety. In order to establish a personalized medicine approach for treating gastric cancer patients, rapid intraoperative detection of malignant lesions has become important. Feasibility of photodynamic diagnosis using 5-aminolevulinic acid for gastric cancer patients has been investigated, especially for the detection of peritoneal dissemination and lymph node metastasis. This method enables intraoperative realtime fluorescence detection of peritoneal dissemination, exhibiting higher sensitivity than white light observation without histopathological examination. The method also enables detection of metastatic foci within excised lymph nodes, exhibiting a diagnostic accuracy comparable to that of a current molecular diagnostics technique. Although several complicating issues still need to be resolved, such as the effect of tissue autofluorescence and the insufficient depth penetration of excitation light, this simple and rapid method has the potential to become a useful diagnostic tool for gastric cancer, as well as urinary bladder cancer and glioma. | Noriaki Koizumi Yoshinori Harada Takeo Minamikawa Hideo Tanaka Eigo Otsuji Tetsuro Takamatsu | 2016 | World Journal of Gastroenterology2016，22，3： | 7 |
| 11 | Skin toxicity predicts efficacy to sorafenib in patients with advanced hepatocellular carcinoma显示文摘AIM:To study the relationship between adverse events(AEs),efficacy,and nursing intervention for sorafenibtherapy in patients with hepatocellular carcinoma(HCC).METHODS:We enrolled 37 consecutive patients withadvanced HCC who received sorafenib therapy.Relationships among baseline characteristics as well as AEoccurrence and tumor response,overall survival(OS),and treatment duration were analyzed.The nursingintervention program consisted of education regardingself-monitoring and AEs management,and telephoneRESULTS:A total of 37 patients were enrolled in the study,comprising 30 males(81%) with a median age of 71 years.The disease control rate at 3 mo was 41%,and the median OS and treatment duration were 259 and 108 d,respectively.Nursing intervention was given to 24 patients(65%).Every patient exhibited some kinds of AEs,but no patients experienced G4 AEs.Frequently observed AEs > G2 included anorexia(57%),skin toxicity(57%),and fatigue(54%).Factors significantly associated with longer OS in multivariate analysis demonstrated that age ≤ 70 years,presence of > G2 skin toxicity,and absence of > G2 hypoalbuminemia.The disease control rate in patients with > G2 skin toxicity was 13/20(65%),which was significantly higher compared with that in patients with no or G1 skin toxicity.Multivariate analysis revealed that nursing intervention and > G2 skin toxicity were independent significant predictors for longer treatment duration.CONCLUSION:Skin toxicity was associated with favorable outcomes with sorafenib therapy for advanced HCC.Nursing intervention contributed to better adher-ence,which may improve the efficacy of sorafenib. | Masako Shomura Tatehiro Kagawa Koichi Shiraishi Shunji Hirose Yoshitaka Arase Tetsuya Mine Jun Koizumi | 2014 | World Journal of Hepatology2014，6，9： | 6 |
| 12 | Clinical usefulness of endoscopic ultrasonography for the evaluation of ulcerative colitis-associated tumors显示文摘AIM:To evaluate the clinical usefulness of endoscopic ultrasonography(EUS) for the diagnosis of the invasion depth of ulcerative colitis-associated tumors.METHODS:The study group comprised 13 patients with 16 ulcerative colitis(UC)-associated tumors for which the depth of invasion was preoperatively estimated by EUS.The lesions were then resected endoscopically or by surgical colectomy and were examined histopathologically.The mean age of the subjects was 48.2 ± 17.1 years,and the mean duration of UC was 15.8 ± 8.3 years.Two lesions were treated by endoscopic resection and the other 14 lesions by surgical colectomy.The depth of invasion of UCassociated tumors was estimated by EUS using an ultrasonic probe and was evaluated on the basis of the deepest layer with narrowing or rupture of the colonic wall.RESULTS:The diagnosis of UC-associated tumors by EUS was carcinoma for 13 lesions and dysplasia for 3 lesions.The invasion depth of the carcinomas was intramucosal for 8 lesions,submucosal for 2,the muscularis propria for 2,and subserosal for 1.Eleven(69%) of the 16 lesions arose in the rectum.The macroscopic appearance was the laterally spreading tumor-non-granular type for 4 lesions,sessile type for 4,laterally spreading tumor-granular type for 3,semipedunculated type(Isp) for 2,type 1 for 2,and type 3 for 1.The depth of invasion was correctly estimated by EUS for 15 lesions(94%) but was misdiagnosed as intramucosal for 1 carcinoma with high-grade submucosal invasion.The 2 lesions treated by endoscopic resection were intramucosal carcinoma and dysplasia,and both were diagnosed as intramucosal lesions by EUS.CONCLUSION:EUS provides a good estimation of the invasion depth of UC-associated tumors and may thus facilitate the selection of treatment. | Kiyonori Kobayashi Kana Kawagishi Shouhei Ooka Kaoru Yokoyama Miwa Sada Wasaburo Koizumi | 2015 | World Journal of Gastroenterology2015，21，9： | 5 |

| 17 | 在脑病理状态下星形胶质细胞介导的突触重塑显示文摘星形胶质细胞是胶质细胞的主要类型,对神经元突触间的信号传递和联系起到反馈作用,构成'三重突触结构'。在大脑发育的过程中,星形胶质细胞的代谢型谷氨酸受体介导钙离子波并释放胶质递质或突触发生分子,介导神经元.胶质细胞间的联系,但在成年大脑中,尚不清楚是否存在此信号通路。但越来越多的证据显示,当成年大脑处于病理状态下,成熟的星形胶质细胞也重新表现出非成熟星形胶质细胞的表型。星形胶质细胞表型的这种非成熟转变可以导致神经环路和突触的重塑。在本综述中,笔者总结了大脑发育过程中星形胶质细胞介导的突触重塑,讨论了成年脑病理过程中非成熟星形胶质细胞信号通路的重现,并重点讨论这些信号通路对病理过程中与脑功能改变有关的突触连接重塑的意义。 | Kim SK Nabekura J Koizumi S 唐颖馨(编译) | 2017 | 神经损伤与功能重建2017，12，4： | 4 |
| 18 | Safety and efficacy of metallic stent for unresectable distal malignant biliary obstruction in elderly patients显示文摘AIM To study the safety of insertion of metallic stents in elderly patients with unresectable distal malignant biliary obstruction.METHODS Of 272 patients with unresectable distal malignant biliary obstruction, 184 patients under the age of 80 were classified into Group A, and 88 subjects aged 80 years or more were classified into Group B. The safety of metallic stent insertion, metal stent patency period, and the obstruction rate were examined in each group.RESULTS In Group B, patients had a significantly worse per-formance status, high blood pressure, heart disease, cerebrovascular disease, and dementia; besides the rate of patients orally administered antiplatelet drugs or anticoagulants tended to be higher(P < 0.05). Metallic stents were successfully inserted in all patients. The median patency period was 265.000 ± 26.779(1-965) d; 252.000 ± 35.998(1-618) d in Group A and 269.000 ± 47.885(1-965) d in Group B, with no significant difference between the two groups. Metallic stent obstruction occurred in 82 of the 272(30.15%) patients; in 53/184(28.80%) patients in Group A and in 29/88(32.95%) of those in Group B, showing no significant difference between the two groups. Procedural accidents due to metal stent insertion occurred in 24/272(8.8%) patients; in 17/184(9.2%) of patients in Group A and in 7/88(8.0%) of those in Group B, with no significant difference between the two groups, either.CONCLUSION These results suggested that metallic stents can be safely inserted to treat unresectable distal malignant biliary obstruction even in elderly patients aged 80 years or more. | Yuji Sakai Tomohisa Iwai Kenji Shimura Katsushige Gon Kazuya Koizumi Masashi Ijima Kazuro Chiba Seigo Nakatani Harutoshi Sugiyama Toshio Tsuyuguchi Terumi Kamisawa Iruu Maetani Mitsuhiro Kida | 2018 | World Journal of Gastroenterology2018，24，1： | 4 |
| 19 | Argon plasma coagulation for superficial esophageal squamous-cell carcinoma in high-risk patients显示文摘AIM: To evaluate the usefulness and safety of argon plasma coagulation (APC) for superficial esophageal squamous-cell carcinoma (SESC) in high-risk patients. METHODS: We studied 17 patients (15 men and 2 women, 21 lesions) with SESC in whom endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), and open surgery were contraindicated from March 1999 through February 2009. None of the patients could tolerate prolonged EMR/ESD or open surgery because of severe concomitant disease (e.g., liver cirrhosis, cerebral infarction, or ischemic heart disease) or scar formation after EMR/ESD and chemoradiotherapy. After conventional endoscopy, an iodine stain was sprayed on the esophageal mucosa to determine the lesion margins. The lesion was then ablated by APC. We retrospectively studied the treatment time, number of APC sessions per site, complications, presence or absence of recurrence, and time to recurrence.RESULTS: The median duration of follow-up was 36 mo (range: 6-120 mo). All of the tumors were macroscopically classified as superficial and slightly depressed type (0-Ⅱc). The preoperative depth of invasion was clinical T1a (mucosal cancer) for 19 lesions and clinical T1b (submucosal cancer) for 2. The median treatment time was 15 min (range: 10-36 min). The median number of treatment sessions per site was 2 (range: 1-4). The median hospital stay was 14 d (range: 5-68 d). Among the 17 patients (21 lesions), 2 (9.5%) had recurrence and underwent additional APC with no subsequent evidence of recurrence. There were no treatment-related complications, such as bleeding or perforation. CONCLUSION: APC is considered to be safe and effective for the management of SESC that cannot be resected endoscopically because of underlying disease, as well as for the control of recurrence after EMR and local recurrence after chemoradiotherapy. | Kumiko Tahara Satoshi Tanabe Kenji Ishido Katsuhiko Higuchi Tohru Sasaki Chikatoshi Katada Mizutomo Azuma Kento Nakatani Akira Naruke Myungchul Kim Wasaburo Koizumi | 2012 | World Journal of Gastroenterology2012，18，38： | 4 |
