| 1 | 为早食道、胃的癌症的诊断的内视镜的超声使用超声探针显示文摘 Endoscopic ultrasound(EUS) devices were first designed and manufactured more than 30 years ago,and since then investigators have reported EUS is effective for determining both the staging and the depth of invasion of esophageal and gastric cancers.We review the present status,the methods,and the findings of EUS when used to diagnose and stage early esophageal and gastric cancer.EUS using high-frequency ultrasound probes is more accurate than conventional EUS for the evaluation of the depth of invasion of superficial esophageal carcinoma.The rates of accurate evaluation of the depth of invasion by EUS using high-frequency ultrasound probes were 70%-88% for intramucosal cancer,and 83%-94% for submucosal invasive cancer.But the sensitivity of EUS using high-frequency ultrasound probes for the diagnosis of submucosal invasive cancer was relatively low,making it difficult to confirm minute submucosal invasion.The accuracy of EUS using highfrequency ultrasound probes for early gastric tumor classification can be up to 80% compared with 63% for conventional EUS,although the accuracy of EUS using high-frequency ultrasound probes relatively decreases for those patients with depressed-type lesions,undifferentiated cancer,concomitant ulceration,expanded indications,type 0-Ⅰ lesions,and lesions located in the upper-third of the stomach.A 92% overall accuracy rate was achieved when both the endoscopic appearance and the findings from EUS using high-frequency ultrasound probes were considered together for tumor classification.Although EUS using high-frequency ultrasound probes has limitations,it has a high depth of invasion accuracy and is a useful procedure to distinguish lesions in the esophagus and stomach that are indicated for endoscopic resection. | Shigetaka Yoshinaga Ichiro Oda Satoru Nonaka Ryoji Kushima Yutaka Saito | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，6： | 21 |
| 2 | Dehiscence following successful endoscopic closure of gastric perforation during endoscopic submucosal dissection显示文摘Gastric perforation is one of the most serious complications that can occur during endoscopic submucosal dissection(ESD).In terms of the treatment of such perforations,we previously reported that perforations immediately observed and successfully closed with endoclips during endoscopic resection could be managed conservatively.We now report the first case in our medical facility of a gastric perforation during ESD that was ineffectively treated conservatively even after successful endoscopic closure.In December 2006,we performed ESD on a recurrent early gastric cancer in an 81-year-old man with a medical history of laparotomy for cholelithiasis.A perforation occurred during ESD that was immediately observed and successfully closed with endoclips so that ESD could be continued resulting in an en-bloc resection.Intensive conservative management was conducted following ESD,however,an endoscopic examination five days after ESD revealed dehiscence of the perforation requiring an emergency laparotomy. | Masau Sekiguchi Haruhisa Suzuki Ichiro Oda Shigetaka Yoshinaga Satoru Nonaka Makoto Saka Hitoshi Katai Hirokazu Taniguchi Ryoji Kushima Yutaka Saito | 2012 | World Journal of Gastroenterology2012，18，31： | 7 |
| 3 | ARID1A expression in gastric adenocarcinoma:Clinicopathological significance and correlation with DNA mismatch repair status显示文摘AIM:To analyze the mismatch repair(MMR)status and the ARID1A expression as well as their clinicopathological significance in gastric adenocarcinomas.METHODS:We examined the expressions of MMR proteins and ARID1A by immunohistochemistry in consecutive 489 primary gastric adenocarcinomas.The results were further correlated with clinicopathological variables.RESULTS:The loss of any MMR protein expression,indicative of MMR deficiency,was observed in 38cases(7.8%)and was significantly associated with an older age(68.6±9.2 vs 60.4±11.7,P<0.001),a female sex(55.3%vs 31.3%,P=0.004),an antral location(44.7%vs 25.7%,P=0.021),and a differentiated histology(57.9%vs 39.7%,P=0.023).Abnormal ARID1A expression,including reduced or loss of ARID1A expression,was observed in 109 cases(22.3%)and was significantly correlated with lymphatic invasion(80.7%vs 69.5%,P=0.022)and lymph node metastasis(83.5%vs 73.7%,P=0.042).The tumors with abnormal ARID1A expression more frequently indicated MMR deficiency(47.4%vs 20.2%,P<0.001).A multivariate analysis identified abnormal ARID1A expression as an independent poor prognostic factor(HR=1.36,95%CI:1.01-1.84;P=0.040).CONCLUSION:Our observations suggest that the AIRD1A inactivation is associated with lymphatic invasion,lymph node metastasis,poor prognosis,and MMR deficiency in gastric adenocarcinomas. | Ryo Inada Shigeki Sekine Hirokazu Taniguchi Hitoshi Tsuda Hitoshi Katai Toshiyoshi Fujiwara Ryoji Kushima | 2015 | World Journal of Gastroenterology2015，21，7： | 7 |
| 4 | Cap polyposis refractory to Helicobacter pylori eradication treated with endoscopic submucosal dissection显示文摘Cap polyposis is a rare intestinal disorder. Characteristic endoscopic findings are multiple inflammatory polypoid lesions covered by caps of fibrous purulent exudate. Although a specific treatment has not been established, some studies have suggested that eradication therapy for Helicobacter pylori(H. pylori) is effective. We report a case of a 20-year-old man with cap polyposis presenting with hematochezia. Colonoscopy showed the erythematous polyps with white caps from the sigmoid colon to rectum. Histopathological findings revealed elongated, tortuous, branched crypts lined by hyperplastic epithelium with a mild degree of fibromusculosis in the lamina propria. Although H. pylori eradication was instituted, there was no improvement over six months. We then performed en bloc excision of the polyps by endoscopic submucosal dissection(ESD), which resulted in complete resolution of symptoms. ESD may be a treatment option for cap polyposis refractory to conservative treatments. We review the literature concerning treatment for cap polyposis and clinical outcomes. | Masaki Murata Mitsushige Sugimoto Hiromitsu Ban Taketo Otsuka Toshiro Nakata Masahide Fukuda Osamu Inatomi Shigeki Bamba Ryoji Kushima Akira Andoh | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，10： | 5 |

| 6 | Efficacy of additional treatment with azathioprine in a patient with prednisolone-dependent gastric sarcoidosis显示文摘Gastric sarcoidosis with noncaseating granuloma is rare. Although corticosteroid produces a dramatic clinical response, it is unknown whether azathioprine show efficacy in prednisolone-dependent cases. Here, we report a case of gastric sarcoidosis in a 25-year-old man with severe epigastlargia. Gastroendoscopy revealed multiple map-like ulcerations. Histological examination showed multiple noncaseating granulomatous lesions in gastric mucosa, which were incompatible with diagnoses of Crohn's disease or tuberculosis. He was started on prednisolone at 30 mg/d, and his symptoms improved within 7-d. The prednisolone was gradually tapered by 5 mg every 2-wk, but oral azathioprine at 50 mg was added after symptoms recurred at tapered dose of 10 mg. Endoscopy 4-wk later showed healing ulcers, and, lymphocytic infiltration was absent. The efficacy of additional azathioprine in gastric sarcoidosis is not well defined. Here, we report a case of prednisolone-dependent gastric sarcoidosis that improved after additional azathioprine, and also review the literature concerning the treatment, especially for prednisolone-dependent cases. | Masaki Murata Mitsushige Sugimoto Yoshihiro Yokota Hiromitsu Ban Osamu Inatomi Shigeki Bamba Ryoji Kushima Akira Andoh | 2016 | World Journal of Gastroenterology2016，22，47： | 3 |
| 7 | Application of novel magnified single balloon enteroscopy for a patient with Cronkhite-Canada syndrome显示文摘We present a case of Cronkhite-Canada syndrome(CCS) in which the entire intestine was observed using a prototype of magnifying single-balloon enteroscope(SIF Y-0007, Olympus). CCS is a rare, non-familial gastrointestinal polyposis with ectodermal abnormalities. To our knowledge, this is the first report showing magnified intestinal lesions of CCS. A 73-year-old female visited our hospital with complaints of diarrhea and dysgeusia. The blood test showed mild anemia and hypoalbuminemia. The esophagogastroduodenoscopy and colonoscopy revealed diffuse and reddened sessile to semi-pedunculated polyps, resulting in the diagnosis of CCS. In addition to the findings of conventional balloon-assisted enteroscopy or capsule endoscopy, magnifying observation revealed tiny granular structures, non-uniformity of the villus, irregular caliber of the loop-like capillaries, scattered white spots in the villous tip, and patchy redness of the villus. Histologically, the scattered white spots and patchy redness of the villus reflect lymphangiectasia and bleeding to interstitium, respectively. | Masaki Murata Shigeki Bamba Kenichiro Takahashi Hirotsugu Imaeda Atsushi Nishida Osamu Inatomi Tomoyuki Tsujikawa Ryoji Kushima Mitsushige Sugimoto Akira Andoh | 2017 | World Journal of Gastroenterology2017，23，22： | 2 |

| 9 | Highly accurate colorectal cancer prediction model based on Raman spectroscopy using patient serum显示文摘BACKGROUND Colorectal cancer(CRC) is an important disease worldwide, accounting for the second highest number of cancer-related deaths and the third highest number of new cancer cases. The blood test is a simple and minimally invasive diagnostic test. However, there is currently no blood test that can accurately diagnose CRC.AIM To develop a comprehensive, spontaneous, minimally invasive, label-free, bloodbased CRC screening technique based on Raman spectroscopy.METHODS We used Raman spectra recorded using 184 serum samples obtained from patients undergoing colonoscopies. Patients with malignant tumor histories as well as those with cancers in organs other than the large intestine were excluded. Consequently, the specific diseases of 184 patients were CRC(12), rectal neuroendocrine tumor(2), colorectal adenoma(68), colorectal hyperplastic polyp(18), and others(84). We used the 1064-nm wavelength laser for excitation. The power of the laser was set to 200 mW.RESULTS Use of the recorded Raman spectra as training data allowed the construction of a boosted tree CRC prediction model based on machine learning. Therefore, the generalized R^2 values for CRC, adenomas, hyperplastic polyps, and neuroendocrine tumors were 0.9982, 0.9630, 0.9962, and 0.9986, respectively.CONCLUSION For machine learning using Raman spectral data, a highly accurate CRC prediction model with a high R^2 value was constructed. We are currently planning studies to demonstrate the accuracy of this model with a large amount of additional data. | Hiroaki Ito Naoyuki Uragami Tomokazu Miyazaki William Yang Kenji Issha Kai Matsuo Satoshi Kimura Yuji Arai Hiromasa Tokunaga Saiko Okada Machiko Kawamura Noboru Yokoyama Miki Kushima Haruhiro Inoue Takashi Fukagai Yumi Kamijo | 2020 | World Journal of Gastrointestinal Oncology2020，12，11： | 2 |

| 11 | Bone metastasis from early gastric cancer following non-curative endoscopic submucosal dissection显示文摘A 67-year-old male underwent endoscopic submucosal dissection(ESD)to treat early gastric cancer(EGC)in 2001.The lesion(50 mm × 25 mm diameter)was histologically diagnosed as poorly differentiated adenocarcinoma,with an ulcer finding.Although the tumor was confined to the mucosa with no evidence of lymphovascular involvement,the ESD was regarded as a noncurative resection due to the histological type,tumor size,and existence of an ulcer finding(as indicated by the 2010 Japanese gastric cancer treatment guidelines,ver.3).Despite strong recommendation for subsequent gastrectomy,the patient refused surgery.An alternative follow-up routine was designed,which included five years of biannual clinical examinations to detect and measure serum tumor markers and perform visual assessment of recurrence by endoscopy and computed tomography scan after which the examinations were performed annually.The patient's condition remained stable for eight years,until a complaint of back pain in 2010 prompted further clinical investigation.Bone scintigraphy indicated increased uptake.Histological examination of biopsy specimens taken from the lumbar spine revealed adenocarcinoma resembling the carcinoma cells from the EGC that had been treated previously by ESD,and which was consistent with immunohistochemical findings of gastrointestinal tract cancer.Thus,the diagnosis of bone metastasis from EGC was made.The reported rates of EGC recurrence in surgically resected cases range 1.4%-3.4%,but among these bone metastasis is very rare.To our knowledge,this is the first reported case of bone metastasis from EGC following a non-curative ESD and occurring after an eight-year disease-free interval. | Hiroyuki Kawabata Ichiro Oda Haruhisa Suzuki Satoru Nonaka Shigetaka Yoshinaga Hitoshi Katai Hirokazu Taniguchi Ryoji Kushima Yutaka Saito | 2013 | World Journal of Gastroenterology2013，19，30： | 2 |
