To establish a standardized management regimen for endoscopic cyanoacrylate injection (ECI) for gastric varices based on the endoscopic operation detail recording system, and to evaluate the application value of this regimen in the evaluation of ECI efficacy.

110 patients with gastric varices due to cirrhosis and portal hypertension who underwent ECI in the Third Affiliated Hospital ofSun Yat-sen University from October 2019 to October 2021 were enrolled. Among them, 88 patients were male and 22 female, aged (53±11) years on average. An endoscopic operation detail recording system was established. A standardized management regimen for liver cirrhosis ECI was established including daily training, preoperative preparation, intraoperative operation highlights, intraoperative emergency plan and postoperative follow-up, etc. At postoperative 1 month, gastroscopy was performed to evaluate the therapeutic effect.

In this study, an endoscopic operation detail recording system was established, which could not only record operation details such as the amount of cyanoacrylate, injection site, injection points, injection time, length of injection needle, diameter of injection needle and compression time after injection, but also included quality indexes such as one-time success rate, incidence rate of needle blockage, cyanoacrylate leakage, cyanoacrylate sticking and physician satisfaction degree, etc. The one-time success rate of ECI was 98.2% (108/110). The incidence of intraoperative adverse events was 14.5% (16/110), including 7 cases of bleeding, 3 cases of cyanoacrylate leakage and 2 cases of cyanoacrylate sticking, 2 cases of cyanoacrylate leakage combined with glue sticking, 1 case of bleeding combined with cyanoacrylate sticking, and 1 case of bleeding combined with cyanoacrylate leakage and sticking after needle extraction. The incidence of early postoperative re-bleeding was 3.6% (4/110), and no delayed bleeding occurred. 82 cases were followed up at postoperative 1 month, and the follow-up rate was 74.5% (82/110). The total effective rate of ECI was 87% (72/82). The effective rate was 59% (49/82) and the significantly effective rate was 28% (23/82).

For liver cirrhosis patients undergoing ECI, the standardized management regimen established by endoscopic operation detail recording system can record the operation details, standardize the operation process and digitally analyze the causes of failure, thereby ensuring high success rate of endoscopic treatment operation.
