| 1 | Management and associated factors of delayed perforation after gastric endoscopic submucosal dissection显示文摘AIM: To identify the actual clinical management and associated factors of delayed perforation after gastric endoscopic submucosal dissection(ESD).METHODS: A total of 4943 early gastric cancer(EGC) patients underwent ESD at our hospital between January 1999 and June 2012. We retrospectively assessed the actual management of delayed perforation. In addition, to determine the factors associated with delayed perforation, after excluding 123 EGC patients with perforations that occurred during the ESD procedure, we analyzed the following clinicopathological factors among the remaining 4820 EGC patients by comparing the ESD cases with delayed perforation and the ESD cases without perforation: age, sex, chronological periods, clinical indications for ESD, status of the stomach, location, gastric circumference, tumor size, invasion depth, presence/absence of ulceration, histological type, type of resection, and procedure time.RESULTS: Delayed perforation occurred in 7(0.1%) cases. The median time until the occurrence of delayed perforation was 11 h(range, 6-172 h). Three(43%) of the 7 cases required emergency surgery, while four were conservatively managed without surgical intervention. Among the 4 cases with conservative management, 2 were successfully managed endoscopically using the endoloop-endoclip technique. The median hospital stay was 18 d(range, 15-45 d). There were no delayed perforation-related deaths. Based on a multivariate analysis, gastric tube cases(OR = 11.0; 95%CI: 1.7-73.3; P = 0.013) were significantly associated with delayed perforation.CONCLUSION: Endoscopists must be aware of not only the identified factors associated with delayed perforation, but also how to treat this complicationeffectively and promptly. | Haruhisa Suzuki Ichiro Oda Masau Sekiguchi Seiichiro Abe Satoru Nonaka Shigetaka Yoshinaga Takeshi Nakajima Yutaka Saito | 2015 | World Journal of Gastroenterology2015，21，44： | 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 | Performance of 18-fluoro-2-deoxyglucose positron emission tomography for esophageal cancer screening显示文摘AIM To evaluate the performance of 18-fluoro-2-deoxyglucose positron emission tomography(FDG-PET) for esophageal cancer(EC) screening.METHODS We retrospectively analyzed the data of consecutive asymptomatic individuals who underwent FDG-PET and esophagogastroduodenoscopy(EGD) simultaneously for cancer screening at our institution from February 2004 to March 2013. In total, 14790 FDG-PET and EGD procedures performed for 8468 individuals were included in this study, and the performance of FDGPET for EC screening was assessed by comparing the results of FDG-PET and EGD, considering the latter as the reference.RESULTS Thirty-two EC lesions were detected in 28 individuals(31 squamous cell carcinomas and 1 adenocarcinoma). The median tumor size was 12.5 mm, and the depths of the lesions were as follows: Tis(n = 12), T1a(n = 15), and T1b(n = 5). Among the 14790 FDG-PET procedures, 51 examinations(0.3%) showed positive findings in the esophagus; only 1 was a true-positive finding. The screen sensitivity, specificity, positive predictive value, and negative predictive value of FDGPET for ECs were 3.6%(95%CI: 0.1-18.3), 99.7%(95%CI: 99.6-99.7), 2.0%(95%CI: 0.0-10.4), and 99.8%(95%CI: 99.7-99.9), respectively. Of the 50 FDG-PET false-positive cases, 31 were observed in the lower esophagus, and gastroesophageal reflux disease was observed in 17 of these 31 cases.CONCLUSION This study is the first to clarify the FDG-PET performance for EC screening. Based on the low screen sensitivity, FDG-PET is considered to be difficult to use as a screening modality for ECs. | Masau Sekiguchi Takashi Terauchi Yasuo Kakugawa Naoki Shimada Yutaka Saito Takahisa Matsuda | 2017 | World Journal of Gastroenterology2017，23，15： | 3 |

| 7 | Successful endoscopic closure of a colonic perforation one day after endoscopic mucosal resection of a lesion in the transverse colon显示文摘A 73-year-old man underwent endoscopic mucosal resection(EMR) of a 20-mm flat elevated lesion on the transverse colon. The morning after the procedure, he started to have severe right upper quadrant pain after his first meal. A computed tomography scan revealed free air and a stomach filled with food. He was diagnosed to have delayed post-EMR intestinal perforation. He underwent emergent colonoscopy and clipping of the perforated site. He was discharged 8 d after the endoscopic closure without the need for surgical intervention. The meal was not the cause of the colon transversum perforation. | Kazuya Inoki Taku Sakamoto Masau Sekiguchi Masayoshi Yamada Takeshi Nakajima Takahisa Matsuda Yutaka Saito | 2016 | World Journal of Clinical Cases2016，4，8： | 1 |
| 8 | Fatal submucosal invasive gastric adenosquamous carcinoma detected at surveillance after gastric endoscopic submucosal dissection显示文摘An 80-year-old man was under annual surveillance esophagogastroduodenoscopy after endoscopic submucosal dissection(ESD) for early gastric cancer(EGC).Two years after the initial ESD, a 0-Ⅱc type metachronous EGC lesion, 8 mm in size, without an ulcer scar, was found in the gastric antrum.The estimated tumor depth was up to the mucosa, and biopsy revealed well and poorly differentiated adenocarcinoma.ESD was performed for this lesion and en bloc resection with negative margins was achieved.Histopathological examination revealed an adenosquamous carcinoma 8 mm in size invading the deep submucosal layer(1600 μm), with lymphovascular invasion, consistent with the diagnosis of non-curative resection.Additional gastrectomy was recommended for this patient; however, two months after the ESD, preoperative computed tomography revealed multiple liver metastases, and the patient was considered as an unsuitable candidate for surgical resection.Systemic chemotherapy was therefore started; however, the patient died of gastric cancer 27 mo after the second ESD.Early gastric adenosquamous carcinoma localized to the mucosa and submucosa is extremely rare and its clinical behavior is not well known.The present report is very significant in that it underscores the distinct possibility of gastric adenosquamous carcinoma being very aggressive and fatal even when detected at an early cancer. | Akinori Shirahige Haruhisa Suzuki Ichiro Oda Masau Sekiguchi Genki Mori Seiichiro Abe Satoru Nonaka Shigetaka Yoshinaga Shigeki Sekine Ryoji Kushima Yutaka Saito Takeo Fukagawa Hitoshi Katai | 2015 | World Journal of Gastroenterology2015，21，14： | 1 |
