NCT05192538

Brief Summary

The purpose of this study was to evaluate the safety and efficacy of endoscopic endoloop pre-test for gastroesophageal reflux before anti-reflux surgery or endoscopic treatment. In the study, the investigators used the novel pre-test to narrow the gastric cardia to control symptoms temporarily to decide whether to undergo irreversible surgery or endoscopic treatment.Thirty patients were enrolled and underwent endoscopic endoloop pre-test treatment. The Primary outcome in this study was measured by the percent reduction in post-procedure GERD symptoms as evidenced by analysis of the GERD-HRQL (Health Related Quality of Life) questionnaire. The secondary outcomes included improvement in esophageal 24-hr pH monitoring, improvement in quality of life questionnaires and safety. Patient follow-up assessments were completed at 7 and 14 days post treatment.

Outcome Measures

Primary Outcomes (10)

  • Improvement in GERD-Health Related Quality of Life (HRQL) questionnaire scores

    GERD-HRQL is a validate questionnaire to evaluate GERD-related esophageal symptoms. The scale range is (0-50); the higher values represents worse outcomes.

Study Arms (1)

Endoscopic endoloop pre-test treatment

EXPERIMENTAL

Endoscopic endoloop pre-test treatment is a less invasive reversible endoscopic treatment to predict whether the gastroesophageal reflux can be alleviated in order to ultimately decide whether to undergo irreversible surgery or endoscopic treatment.

Device: Endoscopic endoloop pre-test treatment

Interventions

A novel endoloop was inserted into the gastric cardia by forceps through the single-channel endoscopy. After adjustment of the endoloop's location and angle, it was anchored onto the edge of the gastric cardia with clip and another 1 or 2 clips were inserted to hold the opposite side of endoloop at about 1/2 circumference. Then the hook was connected with the endoloop, which was tighted by slight pulling together of all the clips.
