RESUMEN
Objective To evaluate the efficacy and safety of magnesium aluminum suspension spraying in treating gastric ulcer after endoscopic submocosal dissection (ESD). Methods We made a prospective analysis of patients with gastric ESD surgery performed between January 2016 and June 2019. They were divided into control group, spraying group, and spraying + oral group on the basis of treatment method. All patients were followed up for 8 weeks to evaluate endoscopic ulcer healing and recovery rate. At the same time, postoperative symptoms and complications such as bleeding were also recorded. SPSS 24.0 software was used for statistical analysis. Results A total of 330 eligible cases were randomly divided into control group (124 cases), spraying group (108 cases), and spraying + oral group (98 cases). The results showed that the postoperative pain incidence in spraying group and spraying + oral group was significantly better than that in the control group (35.48% vs. 17.59%, P<0.01; 35.48% vs. 20.41%, P=0.01). The 4-week ulcer recovery rate was better in spraying + oral group than in the control group. It should be noted that ulcer healing rate achieved 100% for the antrum of patients in spraying + oral group. At the same time, the incidence of postoperative bleeding decreased, and no significant adverse drug reactions were observed during the follow-up. Conclusion Almagate suspension spraying is safe and effective in the treatment of upper gastrointestinal ESD postoperative ulcer. In addition, it can also relieve postoperative pain.
