4在早 colorectal 癌症的内视镜的切除术的组织学的评估的重要性显示文摘 The diagnostic criteria for colonic intraepithelial tumors vary from country to country.While intramucosal adenocarcinoma is recognized in Japan,in Western countries adenocarcinoma is diagnosed only if the tumor invades to the submucosa and accesses the muscularis mucosae.However,endoscopic therapy,including endoscopic mucosal resection(EMR)and endoscopic submucosal dissection(ESD),is used worldwide to treat adenoma and early colorectal cancer.Precise histopathological evaluation is important for the curativeness of these therapies as inappropriate endoscopic therapy causes local recurrence of the tumor that may develop into fatal metastasis.Therefore,colorectal ESD and EMR are not indicated for cancers with massive submucosal invasion.However,diagnosis of cancer with massive submucosal invasion by endoscopy is limited,even when magnifying endoscopy for pit pattern and narrow band imaging and flexible spectral imaging color of enhancement are performed.Therefore,occasional cancers with massive submucosal invasion will be treated by ESD and EMR.Precise histopathological evaluation of these lesions should be performed in order to determine the necessity of additional therapy,including surgical resection.Naohisa Yoshida Yuji Naito Nobuaki Yagi Akio Yanagisawa 2012World Journal of Gastrointestinal Pathophysiology2012,3,2:5
5Efficient hemostatic method for endoscopic submucosal dissection of colorectal tumors显示文摘AIM:To evaluate a new hemostatic method using hemostatic forceps to prevent perforation and perioperative hemorrhage during colonic endoscopic submucosal dissection(ESD).METHODS:We studied 250 cases,in which ESD for colorectal tumors was performed at the Kyoto Prefectural University of Medicine or Nara City Hospital between 2005 and 2010.We developed a new hemostatic method using hemostatic forceps in December 2008 for the efficient treatment of submucosal thick vessels.ESD was performed on 126 cases after adoption of the new method(the adopted group)and the new method was performed on 102 of these cases.ESD was performed on 124 cases before the adoption of the new method (the unadopted group).The details of the new method are as follows:firstly,a vessel was coagulated using the hemostatic forceps in the soft coagulation mode according to the standard procedure,and the coagulated vessel was removed using the forceps in the'endocut' mode without perioperative hemorrhage.Secondly,the partial surrounding submucosa was dissected using the forceps in the endocut mode.In the current study,we evaluated the efficacy of this method.RESULTS:Coagulated vessels were successfully removed using the hemostatic forceps in all 102 cases without severe perioperative hemorrhage.Moderate perioperative hemorrhage occurred in five cases(4.9%);however,it was stopped by immediately reuse of the hemostatic forceps.The partial surrounding submucosa was dissected using the forceps in all 102 cases.In the adopted group,the median operation time was 105 min.The proportion of endoscopic en bloc resection was 92.8%(P<0.01)compared to 80.6%in the unadopted group.The postoperative hemorrhage and perforation rates were 2.3%and 2.3%.The rate of perforation was significantly lower than that in the unadopted group (9.6%,P<0.01).We evaluated the ease of use of this method by allowing our three trainees to performed ESD on 46 cases,which were accomplished without any severe hemorrhage.CONCLUSION:The new method effectively treated submucosal thick vessels and shows promise for the prevention of perforation and perioperative hemorrhage in colonic ESD.Naohisa Yoshida Yuji Naito Munehiro Kugai Ken Inoue Naoki Wakabayashi Nobuaki Yagi Akio Yanagisawa Toshikazu Yoshikawa 2010World Journal of Gastroenterology2010,16,33:4
6Image-enhanced endoscopy for diagnosis of colorectal tumors in view of endoscopic treatment显示文摘Recently,image-enhanced endoscopy(IEE) has been used to diagnose gastrointestinal tumors.This method is a change from conventional white-light(WL) endoscopy without dyeing solution,requiring only the push of a button.In IEE,there are many advantages in diagnosis of neoplastic tumors,evaluation of invasion depth for cancerous lesions,and detection of neoplastic lesions.In narrow band imaging(NBI) systems(Olympus Medical Co.,Tokyo,Japan),optical filters that allow narrow-band light to pass at wavelengths of 415 and 540 nm are used.Mucosal surface blood vessels are seen most clearly at 415 nm,which is the wavelength that corresponds to the hemoglobin absorption band,while vessels in the deep layer of the mucosa can be detected at 540 nm.Thus,NBI also can detect pit-like structures named surface pattern.The flexible spectral imaging color enhancement(FICE) system(Fujifilm Medical Co.,Tokyo,Japan) is also an IEE but different to NBI.FICE depends on the use of spectral-estimation technology to reconstruct images at different wavelengths based on WL images.FICE can enhance vascular and surface patterns.The autofluorescence imaging(AFI) video endoscope system(Olympus Medical Co.,Tokyo,Japan) is a new illumination method that uses the difference in intensity of autofluorescence between the normal area and neoplastic lesions.AFI light comprises a blue light for emitting and a green light for hemoglobin absorption.The aim of this review is to highlight the efficacy of IEE for diagnosis of colorectal tumors for endoscopic treatment.Naohisa Yoshida Nobuaki Yagi Akio Yanagisawa Yuji Naito 2012World Journal of Gastrointestinal Endoscopy2012,4,12:3

11Histological evaluation for chemotherapeutic responses of metastatic lymph nodes in gastric cancer显示文摘AIM: To investigate the effect of preoperative chemotherapy(pre-CTx) for metastatic lymph nodes(MLNs) of gastric cancer(GC). METHODS: A retrospective cohort of patients with advanced GC, who underwent pre-CTx followed by gastrectomy, was reviewed. The histological tumor regression grade(TRG), which considered the percentage of residual cancer in the visible tumor bed, was applied to primary tumors and individual MLNs: G1a(complete response), G1b(< 10%), G2(10%-50%) and G3(> 50%). The clinical response to pre-CTx was retrospectively evaluated using only MLNs information, and we compared the histological and clinical evaluations of MLNs.RESULTS: Twenty-eight patients were enrolled. A total of 438 MLNs were retrieved, and 22(5%), 48(11%), 63(14%) and 305(70%) LNs were assigned as G1 a, G1 b, G2 and G3, respectively. Stratification of the residual MLNs based on the TRGs was as follows: 28 G1 b MLNs(9%), 48 G2 MLNs(15%), and 253 G3 MLNs(76%) in the D1 region; 20(23%), 15(17%), and 52(60%) in the D2 region, respectively. However, no significant correlation was found between TRGs in MLNs and clinical response in the subgroup for which evaluation of clinical response was available.CONCLUSION: Pre-CTx does not provide any outstanding histological benefit for MLNs, and an appropriate D2 lymphadenectomy should routinely be performed to offer the chance of curative resection.Osamu Kinoshita Daisuke Ichikawa Yusuke Ichijo Shuhei Komatsu Kazuma Okamoto Mitsuo Kishimoto Akio Yanagisawa Eigo Otsuji 2015World Journal of Gastroenterology2015,21,48:2

16Gastric carcinoma originating from the heterotopic submucosal gastric gland treated by laparoscopy and endoscopy cooperative surgery显示文摘Gastric carcinoma is derived from epithelial cells in the gastric mucosa. We reported an extremely rare case of submucosal gastric carcinoma originating from the heterotopic submucosal gastric gland(HSG) that was safely diagnosed by laparoscopy and endoscopy cooperative surgery(LECS). A 66-year-old man underwent gastrointestinal endoscopy, which detected a submucosal tumor(SMT) of 1.5 cm in diameter on the lesser-anterior wall of the upper gastric body. The tumor could not be diagnosed histologically, even by endoscopic ultrasound-guided fine-needle aspiration biopsy. Local resection by LECS was performed to confirm a diagnosis. Pathologically, the tumor was an intra-submucosal well differentiated adenocarcinoma invading 5000 μm intothe submucosal layer. The resected tumor had negative lateral and vertical margins. Based on the Japanese treatment guidelines, additional laparoscopic proximal gastrectomy was curatively performed. LECS is a less invasive and safer approach for the diagnosis of SMT, even in submucosal gastric carcinoma originating from the HSG.Taisuke Imamura Shuhei Komatsu Daisuke Ichikawa Hiroki Kobayashi Mahito Miyamae Shoji Hirajima Tsutomu Kawaguchi Takeshi Kubota Toshiyuki Kosuga Kazuma Okamoto Hirotaka Konishi Atsushi Shiozaki Hitoshi Fujiwara Kiyoshi Ogiso Nobuaki Yagi Akio Yanagisawa Takashi Ando Eigo Otsuji 2015World Journal of Gastrointestinal Oncology2015,7,8:1
