Esophageal diseases include esophageal malignant diseases and benign diseases, with a high incidence in our country. Along with the development of the endoscopic technique, many of them which required medical treatment or surgery in the past can now be cured by endoscopic surgery. This article is an overview of long-term follow-up of endoscopic surgery for the common esophageal disease, such as early squamous cell carcinoma, esophageal stricture, achalasia and submucosal tumor of the esophagus.
Objective To systematically review the efficacy and safety of cap-assisted endoscopy in the treatment of esophageal foreign bodies.Methods PubMed, Web of science, The Cochrane Library, EMbase, CNKI and Wanfang were searched by computer for relevant literatures on CAP-assisted endoscopic treatment of esophageal foreign bodies from establishment to November 2022. Data were processed using RevMan 5.4.1. Results Finally, 27 studies were included, including 17 randomized controlled trials, 2 Cohort studies and 8 case-control studies, with a total of 3 619 patients. Meta-analysis results showed that compared with traditional endoscopic treatment, the success rate of removal of esophageal foreign bodies in CAP-assisted endoscopy group was higher (OR=14.43, 95%CI 10.64 to 19.55, P<0.000 01), postoperative complications were fewer (OR=0.30,95%CI 0.23 to 0.38, P<0.000 01), patients had better tolerance (OR=4.07, 95%CI 2.95 to 5.60, P<0.000 01), intraoperative visual field clarity was better (OR=12.00, 95%CI 7.29 to 19.76, P<0.000 01) and operative time was shorter (SMD=−1.83, 95%CI −2.31 to −1.34, P<0.000 01). Conclusion CAP-assisted endoscopic treatment of esophageal foreign bodies is an effective and safe method, worthy of further promotion and application in clinical practice.
