| 18 | Meta-analysis of lymph node metastasis in Siewert type Ⅰ and Ⅱ T1 adenocarcinomas显示文摘AIM To evaluate the incidence of lymph node metastasis(LNM) and its risk factors in patients with Siewert type Ⅰ and type Ⅱ pT1 adenocarcinomas.METHODS We enrolled 85 patients [69 men, 16 women; median age(range), 67(38-84) years] who had undergone esophagectomy or proximal gastrectomy for Siewert type Ⅰ and type Ⅱ pT1 adenocarcinomas. Predictive risk factors of LNM included age, sex, location of the tumor center, confirmed Barrett's esophageal adenocarcinoma, tumor size, macroscopic tumor type, pathology, invasion depth, presence of ulceration, and lymphovascular invasion. Multivariate logistic regression analysis was used to identify factors predicting LNM. We also evaluated the frequencies of LNM for Siewert type Ⅰ and type Ⅱ pT1 adenocarcinomas in meta-data analysis.RESULTS LNMs were found in 11 out of 85 patients(12.9%, 95%CI: 5.8-20.0). Only 1 of the 15 patients(6.6%, 95%CI: 0.0-19.2) who had a final diagnosis of pT1a adenocarcinoma had a positive LNM, whereas 10 ofthe 70 patients(14.2%, 95%CI: 6.0-22.4) with a final diagnosis of pT1b adenocarcinoma had positive LNM. Furthermore, only one of the 30 patients(3.3%, 95%CI: 0.0-9.7) with a tumor invasion depth within 500 μm from muscularis mucosae had positive LNM. Poor differentiation and lymphovascular invasion were independently associated with a risk of LNM. In meta-data analysis, 12 of the 355 patients(3.3%, 95%CI: 1.5-5.2) who had a final diagnosis of pT1a adenocarcinoma had a positive LNM, whereas 91 of the 438 patients(20.7%, 95%CI: 16.9-24.5) with a final diagnosis of pT1b adenocarcinoma had positive LNM. CONCLUSION We consider endoscopic submucosal dissection(ESD) is suitable for patients with Siewert type Ⅰ and type Ⅱ T1 a adenocarcinomas. For patients with T1b adenocarcinoma, especially invasion depth is within 500 μm from muscularis mucosae with no other risk factor for LNM, diagnostic ESD could be a treatment option according to the overall status of patients and the presence of comorbidities. | Hiroki Osumi Junko Fujisaki Masami Omae Tomoki Shimizu Toshiyuki Yoshio Akiyoshi Ishiyama Toshiaki Hirasawa Tomohiro Tsuchida Yorimasa Yamamoto Hiroshi Kawachi Noriko Yamamoto Masahiro Igarashi | 2016 | World Journal of Meta-Analysis2016，4，6： | 0 |
| 19 | Using a novel hemostatic peptide solution to prevent bleeding after endoscopic submucosal dissection of a gastric tumor显示文摘BACKGROUND Endoscopic mucosal dissection has become the standard treatment for early gastric cancer.However,post-endoscopic submucosal dissection(ESD)ulcer occurs in 4.4%of patients.This study hypothesized whether applying PuraStat,a novel hemostatic peptide solution,prevents post-ESD bleeding.AIM To investigate the preventive potential of PuraStat,a hemostatic formulation,against bleeding in post-ESD gastric ulcers.METHODS Between May 2022 and March 2023,101 patients(Group P)underwent ESD for gastric diseases at our hospital and received PuraStat(2 mL)for post-ESD ulcers.We retrospectively compared this group with a control group(Group C)com-prising 297 patients who underwent ESD for gastric diseases at our hospital between April 2017 and March 2021.P values<0.05 on two-sided tests indicated significance.RESULTS Post-ESD bleeding occurred in 6(5.9%)(95%CI:2.8-12.4)and 20(6.7%)(95%CI:4.4-10.2)patients in Groups P and C,respectively,with no significant between-group difference.The relative risk was 1.01(95%CI:0.95-1.07).The lesser curvature or anterior wall was the bleeding site in all 6 patients who experienced postoperative bleeding in Group P.In multivariate analysis,the odds ratios for resection diameter≥50 mm and oral anticoagulant use were 6.63(95%CI:2.52-14.47;P=0.0001)and 4.04(1.26-0.69;P=0.0164),respectively.The adjusted odds ratio of post-ESD bleeding and PuraStat was 1.28(95%CI:0.28-2.15).CONCLUSION PuraStat application is not associated with post-ESD bleeding.However,the study suggests that gravitational forces may affect the effectiveness of applied PuraStat. | Kuniyo Gomi Yorimasa Yamamoto Erika Yoshida Misako Tohata Masatsugu Nagahama | 2024 | World Journal of Gastrointestinal Endoscopy2024，16，3： | 0 |
