| 1 | Lifestyle-related disease in Crohn’s disease: Relapse prevention by a semi-vegetarian diet显示文摘AIM: To investigate whether semi-vegetarian diet (SVD) has a preventive effect against relapse of Crohn’s disease (CD) in patients who have achieved remission,who are a high-risk group for relapse.METHODS: A prospective,single center,2-year clinical trial was conducted.Twenty-two adult CD patients who achieved clinical remission either medically (n = 17) or surgically (n = 5) and consumed an SVD during hospitalization were advised to continue with an SVD and avoid known high-risk foods for inflammatory bowel disease.The primary endpoint was clinical relapse defi ned as the appearance of active symptoms of CD.Kaplan-Meier survival analysis was used to calculate the cumulative proportion of patients who had a relapse.A 2-year analysis of relapse rates of patients who followed an SVD and those who did not (an omnivorous diet group) was undertaken.RESULTS: SVD was continued by 16 patients (compliance 73%).Remission was maintained in 15 of 16 patients (94%) in the SVD group vs two of six (33%)in the omnivorous group.Remission rate with SVD was 100% at 1 year and 92% at 2 years.SVD showed signif icant prevention in the time to relapse compared to that in the omnivorous group (P = 0.0003,log rank test).The concentration of C-reactive protein was normal at the f inal visit in more than half of the patients in remission who were taking an SVD,who maintained remission during the study (9/15;60%),who terminated follow-up (8/12;67%),and who completed 2 years follow-up (7/10;70%).There was no untoward effect of SVD.CONCLUSION: SVD was highly effective in preventing relapse in CD. | Mitsuro Chiba Toru Abe Hidehiko Tsuda Takeshi Sugawara Satoko Tsuda Haruhiko Tozawa Katsuhiko Fujiwara Hideo Imai | 2010 | World Journal of Gastroenterology2010，16，20： | 17 |
| 2 | 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 |
| 3 | 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 |
| 4 | Prospective postsurgical capsule endoscopy in patients with Crohn's disease显示文摘AIM: To clarify the usefulness of postsurgical capsule endoscopy(CE) in the diagnosis of recurrent small bowel lesions of Crohn's disease(CD). METHODS: This prospective study included 19 patients who underwent ileocolectomy or partial ileal resection for CD. CE was performed 2-3 wk after surgery to check for the presence/absence and severity of lesions remaining in the small bowel, and for any recurrence at the anastomosed area. CE was repeated 6-8 mo after surgery and the findings were compared with those obtained shortly after surgery. The Lewis score (LS) was used to evaluate any inflammatory changes of the small bowel. RESULTS: One patient was excluded from analysis because of insufficient endoscopy data at the initial CE. The total LS shortly after surgery was 428.3 on average(median, 174; range, 8-4264), and was ≥ 135(active stage) in 78%(14 of 18) of the patients. When the remaining unresected small bowel was divided into 3 equal portions according to the transition time(proximal, middle, and distal tertiles), the mean LS was 286.6, 83.0, and 146.7, respectively, without any significant difference. Ulcerous lesions in the anastomosed area were observed in 83% of all patients. In 38% of the 13 patients who could undergo CE again after 6-8 mo, the total LS was higher by ≥ 100 than that recorded shortly after surgery, thus indicating a diagnosis of endoscopic progressive recurrence. CONCLUSION: Our pilot study suggests that CE can be used to objectively evaluate the postoperative recurrence of small bowel lesions after surgery for CD. | Tomoaki Kono Nobuyuki Hida Koji Nogami Masaki Iimuro Yoshio Ohda Yoko Yokoyama Koji Kamikozuru Katsuyuki Tozawa Mikio Kawai Tomohiro Ogawa Kazutoshi Hori Hiroki Ikeuchi Hiroto Miwa Shiro Nakamura Takayuki Matsumoto | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，3： | 7 |
| 5 | Lansoprazole-associated collagenous colitis:Diffuse mucosal cloudiness mimicking ulcerative colitis显示文摘There have only been a few reports on lansoprazole-associated collagenous colitis. Colonic mucosa of collagenous colitis is known to be endoscopically normal. We present a case of collagenous colitis where the mucosa showed diffuse cloudiness mimicking ulcerative colitis. A 70-year-old woman developed watery diarrhea four to nine times a day. She had interstitial pneumonia at 67 and reflux esophagitis at 70 years. Lansoprazole 30 mg/d had been prescribed for reflux esophagitis for nearly 6 mo. Lansoprazole was withdrawn due to its possible side effect of diarrhea. Colonoscopy disclosed diffuse cloudiness of the mucosa which suggested ulcerative colitis. Consequently sulfasalazine 2 g/d was started. The patient's diarrhea dramatically disappeared on the following day. However, biopsy specimens showed subepithelial collagenous thickening and infi ltration of inflammatory cells in the lamina propria, confirming the diagnosis of collagenous colitis. One month after sulfasalazine therapy was initiated, colonoscopic and histological abnormalities resolved completely. Five months later the diarrhea recurred. The findings on colonoscopy and histology were the same as before, confirming a diagnosis of collagenous colitis relapse. We found that the patient had begun to take lansoprazole again 3 mo ahead of the recent diarrhea. Withdrawal of lansoprazole promptly resolved the diarrhea. Endoscopic and histological abnormalities were also completely resolved, similar to the first episode. Retrospectively, the date of commencement of sulfasalazine and discontinuation of lansoprazole in the first episode was found to be the same. We conclude that this patient had lansoprazole-associated collagenous colitis. | Mitsuro Chiba Takeshi Sugawara Haruhiko Tozawa Hidehiko Tsuda Toru Abe Takuo Tokairin Iwao Ono Eriko Ushiyama | 2009 | World Journal of Gastroenterology2009，15，17： | 5 |
| 6 | 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 |
