RESUMO
Objective To investigate the clinical value of pharyngeal protection tube in endoscopic therapy for patients with liver cirrhosis and esophagogastric varices. Methods The clinical data of 120 patients from January 2013 to October 2016, suffered from liver cirrhosis and esophagogastric varices, and accepted the endoscopic therapy were analyzed retrospectively. 60 patients underwent endoscopic therapy and were meanwhile applied pharyngeal protection tube; 60 cases were treated with the assistance of routine endoscopy. The completion rate of treatment and the incidence of complications were observed and compared between the two groups. Results Pharyngeal protection tube group: The completion rate of endoscopic treatment in the pharynx protective tube group was 98.3%, without complications. In the control group, the completion rate of the treatment under endoscopy was 88.3%, and there were 7 cases of aspiration, asphyxia and inhalation pneumonia. Conclusions Using pharyngeal protection tube to protect airway can improve the safety and completion rate of endoscopic treatment of esophageal and gastric varices, reduce the incidence of complications, and the pharyngeal protection tube is simple and cost-effective, which is worthy of clinical application.
