Objective: In this study we aimed to compare the need for further examination with conventional gastroscopy within 1 year after magnetically assisted capsule endoscopy (MCCE) examination between patients with gastrointestinal (GI) symptoms and asymptomatic individuals.
Methods: After propensity score matching analysis, 372 patients with GI symptoms and 372 asymptomatic individuals who had undergone MCCE at the First Affiliated Hospital of Sun Yat-sen University from January 1, 2019 to December 30, 2020 were retrospectively enrolled. Demographic and clinical characteristics of the participants and their MCCE and gastroscopic findings (performed within 1 year after MCCE) were analyzed.
Results: Fifty-one (6.85%) patients underwent further examination with conventional gastroscopy within 1 year after MCCE. Those with GI symptoms were more likely to undergo conventional gastroscopy than those without (9.95% vs 3.76%, P < 0.001). Polyps were the most common finding of MCCE. The rate of conventional gastroscopy in patients with focal lesions was significantly higher than that in those without focal lesions (P < 0.05). However, such rate did not differ in the different age groups (P = 0.106).
Conclusions: MCCE is an optimal alternative for gastric examination, especially for large-scale screening of asymptomatic individuals. Patients with GI symptoms or focal lesions detected by MCCE are more likely to seek further examination with conventional gastroscopy for biopsy or endoscopic treatment than those without.
