Objective:To review publications in the field of digestive endoscopic minimally-invasive resection in the past 10 years in and outside China.Methods:Literature of digestive endoscopic minimally-invasive resection in the Web of Science and CNKI databases from January 1, 2011 to July 17, 2021 was retrieved. VOSviewer 1.6.11 was used for clustering and time series analysis of countries, institutions, authors and keywords, and drawing evidence-based visualization maps, so as to analyze the cooperation among countries, academic institutions and researchers, to compare the differences in research topics between Chinese and English databases, and to predict the future research hot spots and directions.Results:A total of 22 834 English articles and 4 636 Chinese articles were included. Over the past 10 years, the number of Chinese and English publications has been growing steadily, and most of them were published in professional journals. The publications were mainly from China, Japan, South Korea and the United States, where all exceeded 2 000. The National Cancer Center of Japan had 497 publications, ranking the first among all institutions. The cooperation between academic institutions showed obvious regional characteristics, and the inter-institutional and interpersonal cooperation needed improvement. In terms of keyword clustering, there was no significant difference between Chinese and English publications, but there were two additional clusters in Chinese publications, endoscopic nursing and submucosal tumor. Overlays analysis of key words showed that endoscopic surgery, tunneling technique, and submucosal tumor could be hot spots and future directions.Conclusion:Digestive endoscopic minimally-invasive resection has experienced a vigorous development in the past 10 years with a growing number of Chinese and English publications. China is playing an increasingly important role on the international stage. The advanced nature of research focus in Chinese publications is comparable to that in English publications, yet also showing Chinese characteristics. In the future, more efforts should be taken to strengthen regional cooperation and focus on research hot spots.

Objective To explore the feasibility, safety, and efficacy of transesophageal endoscopic surgery for mediastinal tumors. Methods A retrospective analysis was conducted on the clinical data of 17 patients who underwent transesophageal endoscopic resection for benign mediastinal tumors at the Endoscopy Center of Zhongshan Hospital, Fudan University, between January 1, 2016 and December 31, 2024. Epidemiological characteristics, surgical parameters, adverse events, and follow-up outcomes were analyzed. Results Among the 17 patients, there were 9 males and 8 females, with an average age of (42.4±14.5) years and an average tumor size of (2.6±1.6) cm. Pathological types included esophageal duplication cysts (6 cases, 35.3%), bronchogenic cysts (5 cases, 29.4%), gastroenteric cysts (3 cases, 17.6%), schwannomas (2 cases, 11.8%), and lymphangioma (1 case, 5.9%). Fourteen patients (82.4%) underwent submucosal tunneling endoscopic resection (STER), 3 patients (17.6%) underwent natural orifice transluminal endoscopic mediastinal surgery. All surgeries were successfully completed without conversion to open surgery. En bloc resection was achieved in 11 patients (64.7%), with an average operative time of (60.9±32.6) min. No intraoperative bleeding or mucosal injury occurred, and 4 patients (23.5%) experienced minor complications (pneumothorax, fever, recurrent laryngeal nerve injury), all of which resolved with conservative treatment. The average postoperative hospital stay was (3.2±1.5) days, and no recurrence was observed during the follow-up period. Conclusions Transesophageal endoscopic resection of benign mediastinal tumors is a safe, effective, and minimally invasive treatment method. Further validation of its efficacy and safety through large-scale prospective studies is warranted.
