Not yet recruiting

• Conditions: Atrophic Gastritis

• Registration Number: NCT06751212
• Lead Sponsor: Xiuli Zuo

Brief Summary

The aim of this observational study was to understand the effect of radiofrequency ablation on subjects with moderate to severe gastric atrophy with enterocolitis with or without low-grade intraepithelial neoplasia who underwent radiofrequency ablation. The main question it aims to answer is:

Does radiofrequency ablation therapy reduce gastric mucosal atrophy and enterosis in subjects with moderate to severe gastric atrophy with enterosis with or without low-grade intraepithelial neoplasia?

Detailed Description

Outpatient or inpatient collection of study participants was done by recruiting participants who met the inclusion criteria and did not meet the exclusion criteria and signed an informed consent form. Study participants were identified for enrollment and a case report form was completed. The basic demographic information of the study participants was recorded, along with the results of existing routine laboratory tests, and symptom-related clinical characteristics. Gastroenterology reports and pathology reports were retained for enrolled study participants to score and grade each study participant specifically, and all study participants were treated with radiofrequency ablation after enrollment. Follow-up gastroscopy was performed on study participants 3 months after treatment, adverse reactions during the two gastroscopies were recorded and case report forms were supplemented, gastroscopy reports and pathology reports of study participants were retained again, and gastroscopy reports and pathology reports of study participants were evaluated, and data on changes were summarized. Follow-up gastroscopy was performed on study participants 3 months after treatment, adverse reactions during the two gastroscopies of study participants were recorded and additional case report forms were completed, gastroscopy reports and pathology reports of study participants were again retained and gastroscopy reports and pathology reports of study participants were evaluated, and data on changes were summarized. Study participants who failed treatment but did not develop new intraepithelial neoplasia summarized the reasons for their failure and were re-treated with radiofrequency ablation 3 months later, and this was repeated until treatment was successful; study participants who developed new low-grade intraepithelial neoplasia were treated with radiofrequency ablation at post-treatment follow-up, and this was repeated until treatment was successful; and study participants who developed new intermediate- and high-grade intraepithelial neoplasia were treated with ESD at post-treatment follow-up, and this was repeated until treatment was successful. All data were summarized at the end of enrollment for all study participants and statistically analyzed.
