Obj.ctive: Magnetically controlled caps.le gas.ros.opy (MCCG) is.an effective method for s.reening gas.ric dis.as.s. however, its.performance may be affected by gas.ric cleanlines.. We aimed to explore the correlation between helicobacter pylori infection and the degree of gas.ric cleanlines. in the MCCG. Methods. This.retros.ective s.udy enrolled 297 participants.from October 2020 to April 2024 at s.r Run Run s.aw hos.ital, Zhej.ang Univers.ty s.hool of Medicine. Participant characteris.ics. MCCG examination res.lts. and (13) C-urea breath tes. (C13-UBT) res.lts.were collected. The gas.ric cleanlines. in MCCG examinations.was.as.es.ed us.ng a gas.ric cleanlines. s.ore. Binary logis.ic regres.ion was.us.d to analyze the relations.ips.among participant characteris.ics. h. pylori infection, and gas.ric cleanlines.. Chi-s.uare tes.s.and Fis.er's.exact tes.s.were us.d to analyze the relations.ips.among gas.ric les.ons. h. pylori infection, and gas.ric cleanlines.. Res.lts. Among the participants. 24.2% had h. pylori infection, and 17.5% had poor gas.ric cleanlines.. hypertens.on (odds.ratio [OR]: 2.63; 95% confidence interval [CI]: 1.36–5.09; p = 0.004) was.as.ociated with a greater likelihood of h. pylori infection. h. pylori infection (OR: 3.76; 95% CI: 1.99–7.09; p s.an independent ris. factor for poor gas.ric cleanlines. in the MCCG. A s.gnificant dis.arity was.noted in the prevalence of focal eros.ons.(p s.ric ulcers.(p = 0.001), and pos.tive gas.ric les.ons.(p = 0.027) between the 2 groups.with and without h. pylori infection. The proportion of pos.tive gas.ric les.ons.was.not s.gnificantly different between the good gas.ric cleanlines. group and the poor gas.ric cleanlines. group (25.7% vs. 21.2%; p = 0.490). Conclus.on: The findings.of this.s.udy revealed that h. pylori infection was.as.ociated with hypertens.on. h. pylori infection may lead to poor gas.ric cleanlines.. Ins.itutions.are advis.d to perform C13-UBT before MCCG, and participa
