Comparison of anti-reflux mucosectomy and endoscopic cardial constriction ligation on treatment of gastroesophageal reflux disease / 中华消化内镜杂志

ABSTRACT

Objective:To compare the clinical efficacy of anti-reflux mucosectomy (ARMS) and endoscopic cardial constriction ligation (ECCL) on treatment of gastroesophageal reflux disease.Methods:A retrospective study was conducted on the data of 48 consecutive patients with gastroesophageal reflux disease, who underwent ARMS or ECCL at the First Affiliated Hospital of Zhengzhou University from December 2015 to August 2018. Twenty cases were in the ARMS group and 28 cases in the ECCL group. The short-term and long-term efficacies were compared between the two groups.Results:The success rate of operation was 100.0% in the both groups. The operation time of the ECCL group was significantly shorter than that of the ARMS group (8.43±1.59 min VS 34.05±12.35 min, t=-9.227, P<0.001). After 2 months follow-up, the symptom improvement rate of the ECCL group and the ARMS group was 89.3% (25/28) and 60.0% (12/20), respectively ( χ2=4.128, P=0.042). The GERD Q score of the ECCL group was significantly lower than that of the ARMS group (6.24 ±1.22 VS 7.35±1.79, t=-2.400, P=0.023). One year after operation, there were no significant differences in the symptom improvement rate, GERD Q score, DeMeester score and the time percentage of pH<4 between the two groups ( P>0.05). Conclusion:The long-term clinical effect of ARMS and ECCL is similar, but the short-term clinical effect of ECCL is superior to ARMS.
