| 1 | Clinical outcomes and risk factors for perforation in gastric endoscopic submucosal dissection: A prospective pilot study显示文摘AIM: To evaluate clinical outcomes and risk factors for endoscopic perforation during endoscopic submucosal dissection (ESD) in a prospective study. METHODS: We investigated the clinical outcomes and risk factors for the development of perforation in 98 consecutive gastric neoplasms undergoing ESD regarding. Demographic and clinical parameters including patient-, tumor-, and treatment-related factors, clinical parameters, and duration of hospital stay were analyzed for risk factors for perforation. In subgroup analysis, we also compared the clinical outcomes between perforation and 'silent' free air without endoscopically visible perforation detected only by computed tomography.RESULTS: Perforation was identified in 8.2% of patients. All patients were managed conservatively by the administration of antibiotics. The mean procedure time was significantly longer in patients with endoscopic perforation than in those without. According to the receiver-operating characteristic analysis, the resulting cutoff value of the procedure time for perforation was 115 min (87.5% sensitivity, 56.7% specificity). Prolonged procedure time (≥ 115 min) was associated with an increased risk of perforation (odds ratio 9.15; 95%CI: 1.08-77.54; P = 0.04). Following ESD, body temperature and C-reactive protein level were significantly higher in patients with perforation than in those without (P = 0.02), whereas there was no difference between these patient groups on the starting day of oral intake or of hospitalization. In subgroup analysis, the post-ESD clinical course was not different between endoscopic perforation and silent free air. CONCLUSION: Only prolonged procedure time (≥ 115 min) was significantly associated with perforation. The clinical outcomes of perforation are favorable and are comparable to those of patients with or without silent free air. | Jiro Watari Toshihiko Tomita Fumihiko Toyoshima Jun Sakurai Takashi Kondo Haruki Asano Takahisa Yamasaki Takuya Okugawa Hisatomo Ikehara Tadayuki Oshima Hirokazu Fukui Hiroto Miwa | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，6： | 17 |
| 2 | Development of Helicobacter pylori treatment: How do we manage antimicrobial resistance?显示文摘Helicobacter pylori(H. pylori) antimicrobial resistance is an urgent, global issue. In2017, the World Health Organization designated clarithromycin-resistant H.pylori as a high priority bacterium for antibiotic research and development. In addition to clarithromycin, resistance to metronidazole and fluoroquinolones has also increased worldwide. Recent international guidelines for management of H.pylori infection recommend bismuth or non-bismuth quadruple therapy for 14 d as a first-line treatment for H. pylori in areas of high clarithromycin and/or metronidazole resistance. Although these treatment regimens provide acceptable H. pylori eradication rates, the regimens used should not contribute to future resistance of H. pylori to antimicrobials. Moreover, these regimens can promote resistance, due to prolonged therapy with multiple antibiotics. A new strategy that can eradicate H. pylori as well as reduce the antibiotics used is required to prevent future antimicrobial resistance in H. pylori. Dual-therapy with vonoprazan and amoxicillin could be a breakthrough for H. pylori eradication in an era of growing antimicrobial resistance. This regimen may provide a satisfactory eradication rate of H. pylori and also minimize antimicrobial resistance due to single antibiotic use and the strong inhibitory effect of vonoprazan on gastric acid secretion. | Sho Suzuki Mitsuru Esaki Chika Kusano Hisatomo Ikehara Takuji Gotoda | 2019 | World Journal of Gastroenterology2019，25，16： | 17 |
| 3 | Appendix is a priming site in the development of ulcerative colitis显示文摘AIM: The role of the appendix has been highlighted in the pathogenesis of ulcerative colitis (UC). The aims of this study were to elucidate the immuno-imbalances in the appendix of UC patients, and to clarify the role of the appendix in the development of UC.METHODS: Colonoscopic biopsy specimens of the appendix, transverse colon, and rectum were obtained from 86 patients with UC: active pancotitis (A-Pan; n = 15),active left-sided colitis (A-Lt; n = 25), A-Lt with appendiceal involvement (A-Lt/Ap; n = 10), inactive pancolitis (I-Pan;n = 14), and inactive left-sided colitis (I-Lt; n = 22),and from controls. In the isolated mucosal T cells, the CD4/CD8 ratio and proportion of activated CD4+ T cells were investigated, and compared with controls.RESULTS: In the appendix, the CD4/CD8 ratio significantly increased in A-Lt and A-Lt/Ap. The ratio in the appendix also tended to increase in A-Pan. In the rectum, the ratio significantly increased in all UC groups. Tn the appendix,the proportion of CD4+CD69+ (early activation antigen)T cells significantly increased in all UC groups. Tn the rectum, the proportion of CD4+CD69+ T cells significantly increased only in A-Pan. The proportion of CD4+HLADR+ (mature activation antigen) T cells significantly increased only in the rectum of A-Pan, but not in the other areas of any groups.CONCLUSION: The increased CD4/CD8 ratio and predominant infiltration of CD4+CD69+ T cells in the appendix suggest that the appendix is a priming site in the development of UC. | Mitsunobu Matsushita Hiroshi Takakuwa Yuji Matsubayashi Akiyoshi Nishio Susumu Ikehara Kazuichi Okazaki | 2005 | World Journal of Gastroenterology2005，11，31： | 9 |
| 4 | What types of early gastric cancer are indicated for endoscopic ultrasonography staging of invasion depth?显示文摘AIM To clarify the diagnostic efficacy and limitations of endoscopic ultrasonography(EUS) and the characteristics of early gastric cancers(EGCs) that are indications for EUS-based assessment of cancer invasion depth.METHODS We retrospectively investigated the cases of 153 EGC patients who underwent conventional endoscopy(CE) and EUS(20 MHz) before treatment.RESULTS We found that 13.7% were 'inconclusive' cases with low-quality EUS images, including all nine of the cases with protruded(0-I)-type EGCs. There was no significant difference in the diagnostic accuracybetween CE and EUS. Two significant independent risk factors for misdiagnosis by EUS were identified-ulcer scarring [UL(+); odds ratio(OR) = 4.49, P = 0.003] and non-indication criteria for endoscopic resection(ER)(OR = 3.02, P = 0.03). In the subgroup analysis, 23.1% of the differentiated-type cancers exhibiting SM massive invasion(SM2) invasion(submucosal invasion ≥ 500 μm) by CE were correctly diagnosed by EUS, and 23.1% of the undifferentiated-type EGCs meeting the expanded-indication criteria for ER were correctly diagnosed by EUS.CONCLUSION There is no need to perform EUS for UL(+) EGCs or 0-I-type EGCs, but EUS may enhance the pretreatment staging of differentiated-type EGCs with SM2 invasion without UL or undifferentiated-type EGCs revealed by CE as meeting the expanded-indication criteria for ER. | Jiro Watari Shigemitsu Ueyama Toshihiko Tomita Hisatomo Ikehara Kazutoshi Hori Ken Hara Takahisa Yamasaki Takuya Okugawa Takashi Kondo Tomoaki Kono Katsuyuki Tozawa Tadayuki Oshima Hirokazu Fukui Hiroto Miwa | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，16： | 8 |
| 5 | Endoscopic diagnosis and treatment of superficial nonampullary duodenal tumors显示文摘The diagnostic and treatment guidelines of superficial non-ampullary duodenal tumors have not been standardized due to their low prevalence.Previous reports suggested that a superficial adenocarcinoma(SAC) should be treated via local resection because of its low risk of lymph node metastasis,whereas a highgrade adenoma(HGA) should be resected because of its high risk of progression to adenocarcinoma.Therefore,pretreatment diagnosis of SAC or HGA is important to determine the appropriate treatment strategy.There are certain endoscopic features known to be associated with SAC or HGA,and current practice prioritizes the endoscopic and biopsy diagnosis of these conditions.Surgical treatment of these duodenal lesions is often related to high risk of morbidity,and therefore endoscopic resection has become increasingly common in recent years.Endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD) are the commonly performed endoscopic resection methods.EMR is preferred due to its lower risk of adverse events;however,it has a higher risk of recurrence than ESD.Recently,a new and safer endoscopic procedure that reduces adverse events from EMR or ESD has been reported. | Mitsuru Esaki Sho Suzuki Hisatomo Ikehara Chika Kusano Takuji Gotoda | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，9： | 7 |
| 6 | Efficacy of intra-arterial contrast-enhanced ultrasonography during transarterial chemoembolization with drug-eluting beads for hepatocellular carcinoma显示文摘AIM To assess the usefulness of intra-arterial contrastenhanced ultrasonography(IAUS) during transarterial chemoembolization(TACE) with drug-eluting beads(DEB) for hepatocellular carcinoma(HCC).METHODS Thirty two patients with 39 HCC underwent DEB-TACE guided with IAUS, and examined by contrast-enhanced ultrasonography(CEUS) or dynamic CT after DEB-TACE were enrolled in this study. CEUS findings before DEBTACE and IAUS findings were compared. Treatments judged to be complete and incomplete for lesions were appropriate and insufficient, respectively. Findings on CEUS and/or dynamic CT performed 1, 3 and 6 mo after DEB-TACE were evaluated using m RECIST(CR/PR/SD/PD).RESULTS The treatments were complete and incomplete in 26 and 13 lesions, respectively. On imaging evaluation using CEUS and/or dynamic CT one month after treatment, 25 and 1 lesions were judged to be CR and PR, respectively, and at 6 mo after treatment, the results were CR, PR, SD and PD for 24, 1, 0 and 1 of these lesions, respectively, in the 26 completely treated lesions. Of the 13 lesions in which treatment was incomplete, the results on imaging at one month after treatment were CR, PR, SD and PD for 0, 6, 4 and 3 lesions, respectively. The overall CR rate at 6 mo after treatment was 61.5%(24/39).CONCLUSION A combination of DEB-TACE with IAUS can improve the therapeutic effects in patients with HCC. | Kazue Shiozawa Manabu Watanabe Takashi Ikehara Shuhei Yamamoto Takashi Matsui Yoshinori Saigusa Yoshinori Igarashi Iruru Maetani | 2018 | World Journal of Hepatology2018，10，1： | 7 |
| 7 | Histological diagnosis of gastric submucosal tumors: A pilot study of endoscopic ultrasonography-guided fine-needle aspiration biopsy vs mucosal cutting biopsy显示文摘AIM: To compare the usefulness of endoscopic ultrasonography-guided fine-needle aspiration biopsy(EUS-FNAB) without cytology and mucosal cutting biopsy(MCB) in the histological diagnosis of gastric submucosal tumor(SMT).METHODS: We prospectively compared the diagnostic yield, feasibility, and safety of EUS-FNAB and those of MCB based on endoscopic submucosal dissection. The cases of 20 consecutive patients with gastric SMT ≥1 cm in diameter. who underwent both EUS-FNAB and MCB were investigated.RESULTS: The histological diagnoses were gastrointestinal stromal tumors(n = 7), leiomyoma(n =6), schwannoma(n = 2), aberrant pancreas(n = 2), and one case each of glomus tumor, metastatic hepatocellular carcinoma, and no-diagnosis. The tumors' mean size was 23.6 mm. Histological diagnosis was made in 65.0% of the EUS-FNABs and 60.0% of the MCBs, a nonsignificant difference. There were no significant differences in the diagnostic yield concerning the tumor location or tumor size between the two methods. However, diagnostic specimens were significantly more frequently obtained in lesions with intraluminal growth than in those with extraluminal growth by the MCB method(P = 0.01). All four SMTs with extraluminal growth were diagnosed only by EUSFNAB(P = 0.03). No complications were found in either method.CONCLUSION: MCB may be chosen as an alternative diagnostic modality in tumors showing the intraluminal growth pattern regardless of tumor size, whereas EUSFNAB should be performed for SMTs with extraluminal growth. | Hisatomo Ikehara Zhaoliang Li Jiro Watari Masato Taki Tomohiro Ogawa Takahisa Yamasaki Takashi Kondo Fumihiko Toyoshima Tomoaki Kono Katsuyuki Tozawa Yoshio Ohda Toshihiko Tomita Tadayuki Oshima Hirokazu Fukui Ikuo Matsuda Seiichi Hirota Hiroto Miwa | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，14： | 7 |

| 11 | Comparison of percutaneous radiofrequency ablation and CyberKnife®for initial solitary hepatocellular carcinoma:A pilot study显示文摘AIM To compare therapeutic outcomes and adverseevents in initial solitary hepatocellular carcinoma(HCC) treated with radiofrequency ablation (RFA) andCyberKnife?.METHODS: Seventy three consecutive patients withinitial solitary HCC treated with RFA (38 patients;RFA group) and CyberKnife (35 patients; CK group)were enrolled in this study. Background factorswere compared between the two groups. Local andintrahepatic distant recurrence control, and cumulativesurvival rates were compared between the two groups.These were determined using the Kaplan-Meier method,and the significance of differences was analyzed by log-rank test. The presence of more grade 3 on CTCAE ver.4.0 early and late adverse events was investigated.RESULTS: In background factors, age was significantlyhigher (P = 0.005) and the tumor diameter wassignificantly larger (P = 0.001) in the CK group. The1-year local recurrence control rates were 97.4%and 97.1% in the RFA and CK groups, respectively (P= 0.71); the 1-year intrahepatic distant recurrencecontrol rates were 85.6% and 86.1%, respectively (P= 0.91); and the 1-year cumulative survival rates were100% and 95.2%, respectively (P = 0.075), showingno significant difference in any rate between the twogroups. There were no late adverse event in the RFAgroup, but 11.4% in the CK group had late adverseevents. In the CK group, the Child-Pugh score at 12 moafter treatment was significantly higher than that in theRFA group (P = 0.003) and significantly higher than thescore before treatment (P = 0.034).CONCLUSION: The occurrence of adverse events is aconcern, but CyberKnife treatment is likely to becomean important option for local treatment of early HCC. | Kazue Shiozawa Manabu Watanabe Takashi Ikehara Yasushi Matsukiyo Michio Kogame Yui Kishimoto Yusuke Okubo Hiroyuki Makino Nobuhiro Tsukamoto Yoshinori Igarashi Yasukiyo Sumino | 2015 | World Journal of Gastroenterology2015，21，48： | 4 |
| 12 | Diagnosis of small intramucosal signet ring cell carcinoma of the stomach by non-magnifying narrow-band imaging: A pilot study显示文摘AIM: To examine the efficacy of non-magnifying narrow-band imaging(NM-NBI) imaging for small signet ring cell carcinoma(SRC).METHODS: We retrospectively analyzed 14 consecutive small intramucosal SRCs that had been treated with endoscopic submucosal dissection(ESD) and 14 randomly selected whitish gastric ulcer scars(control). The strength and shape of the SRCs and whitish scars by NM-NBI and white-light imaging(WLI) were assessed with Image J(NIH, Bethesda).RESULTS: NM-NBI findings of SRC showed a clearly isolated whitish area amid the brown color of the surrounding normal mucosa. The NBI index, which indicates the potency of NBI for visualizing SRC, was significantly higher than the WLI index(P = 0.001), indicating SRC was more clearly identified by NM-NBI. Although the NBI index was not significantly different between SRCs and controls, the circle(C)-index, as an index of circularity of tumor shape, was significantly higher in SRCs(P = 0.001). According to the receiveroperating characteristic analysis, the resulting cut-off value of the circularity index(C-index) for SRC was 0.60(85.7% sensitivity, 85.7% specificity). Thus a lesion with a C-index ≥ 0.6 was significantly more likely to be an SRC than a gastric ulcer scar(OR = 36.0; 95%CI: 4.33-299.09; P = 0.0009).CONCLUSION: Small isolated whitish round area by NM-NBI endoscopy is a useful finding of SRCs which is the indication for ESD. | Jiro Watari Toshihiko Tomita Hisatomo Ikehara Masato Taki Tomohiro Ogawa Takahisa Yamasaki Takashi Kondo Fumihiko Toyoshima Jun Sakurai Tomoaki Kono Katsuyuki Tozawa Yoshio Ohda Tadayuki Oshima Hirokazu Fukui Seiichi Hirota Hiroto Miwa | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，12： | 4 |

| 18 | Endoscopic resection for residual lesion of metastatic gastric cancer:A case report显示文摘BACKGROUND Chemotherapy is a standard strategy for stage IV gastric cancer patients.However, some cases cannot undergo conversion surgery because of their frailty,even if the patients had response to chemotherapy. For these patients, local tumor progression is a problem. We report here the case of a patient whose residual gastric cancer was resected through endoscopic submucosal dissection(ESD)after concomitant chemotherapy for metastatic gastric cancer.CASE SUMMARY An 85-year-old male complained of difficulty swallowing, and examination revealed gastric cancer with multiple liver metastases. Although he received concomitant chemotherapy, a residual tumor was observed in the primary lesion while the metastatic lesions disappeared completely. Conversion surgery was considered optional treatment; however, he could not undergo that because of advanced age and comorbidities. Thus, we performed ESD to treat the residual tumor. As a result, we resected the residual lesion completely. The patient has been alive for 29 mo since ESD, without recurrence.CONCLUSION We achieved local control using ESD, and these findings may provide therapeutic improvements both in local control and patient survival outcomes. | Kaori Hayashi Sho Suzuki Hisatomo Ikehara Hiroaki Okuno Akira Irie Mitsuru Esaki Chika Kusano Takuji Gotoda Mitsuhiko Moriyama | 2019 | World Journal of Clinical Cases2019，7，4： | 2 |
