摘　　要：BACKGROUND Colon capsule endoscopy(CCE),which became clinically applicable in 2006,is a simple and noninvasive procedure to evaluate colonic diseases;the accuracy of second-generation CCE,introduced in 2009,has dramatically improved.Currently,CCE is used as an alternative method for colorectal cancer screening,as well as for evaluating the mucosal lesions of inflammatory bowel disease,in cases where performing colonoscopy(CS)is difficult.However,the outcomes of CCE are uncertain.AIM To investigate the outcomes of Japanese patients with negative findings(no polyps or colorectal cancer)on initial CCE.METHODS This retrospective,single-center study was conducted at the Endoscopic Center at Aishinkai Nakae Hospital.This study included patients who underwent continuous CCE between November 2013 and August 2019,that exhibited no evidence of polyps or colorectal cancer at the initial CCE,and could be followed up using either the fecal immunochemical test(FIT),CS,or CCE.The observational period,follow-up method,presence or absence of polyps and colorectal cancer,pathological diagnosis,and number of colorectal cancer deaths were evaluated.RESULTS Thirty-one patients(mean age,60.4±15.6 years;range,28–84 years;14 men and 17 women)were enrolled in this study.The reasons for performing the first CCE were screening in 12,a positive FIT in six,lower abdominal pain in nine,diarrhea in two,and anemia in two patients.The mean total water volume at the time of examination was 3460±602 mL(2250–4800 mL),and a total CS was performed in 28 patients(90%).The degree of cleanliness was excellent in 15 patients and good in 16,and no poor cases were observed.No adverse events,such as retention or capsule aspiration,were observed in any of the patients.The mean follow-up period was 3.1±1.5 years(range,0.3–5.5 years).Follow-up included FIT in nine,CS in 20,and CCE in four patients(including duplicate patients).The FIT was positive in two patients,while CS revealed five polyp lesions(three in the ascending colon,one in the transverse c
