| purpose This study collected 13716 cases in Gansu people’s hospital from January 2014 to December 2016 in endoscopy center of colonoscopy.According to the detection of diseases,and analyzing large intestine diseases in Gansu province,and analysis of all kinds of all ages disease detection rate corresponding change,the paper to check out the disease and to explore the pathogenesis of the disease detection rate,high risk,the corresponding relationship between pathological type so that Clinicians to each disease having a comprehensive understanding of it,and guide physicians in the clinical diagnosis.method All cases Collected in this study are conform to the standards as study group,with age and gender as a variable analysis of CRC,colorectal polyps,UC,IC,MC diseases such as detection rate of the corresponding change.The stated colonoscopy results use colorectal cancer,colorectal polyps as research group,and through further study to find the corresponding relationship among colorectal cancer,detection of colorectal polyps and pathological type with age changes.results 1 CRC,results in male detection rate of colorectal polyps was obviously higher than that of female;In diseases such as MC,the MC,the nonspecific colitis,female detection rate are higher than men,which has a statistical significance.The results of detection rate in UC neutral shows that there is no obvious difference in gender in terms of colorectal polyps.2 The detectionrate of CRC,colorectal polyps,and MC shows that the detectionrate of elderly patients is higher than young and middle-aged group(P < 0.05).3 The detectionrate of UC manifests that young group is higher than middle-aged and elderly group(P < 0.05).4 The detection of CRC and colorectal polyps parts suggests thatthe location of CRCis associated with age,difference in comparation amongall ages was statistically significant(P < 0.05),the tumor location of all ages were mainly the rectum.5 The number of female patients is larger than male in terms of normal performance under colonoscopy.And young group is larger than middle aged as well as the elder group.(P < 0.05)6 In CRC pathological types,the detection rate of adenocarcinomais the highest,clinical pathologic types of colorectal cancer is associated with each age group(P < 0.05).7 In colorectal polyps pathological types,the detection rate of adenoma is the highest.Colorectal polyps of the clinical pathological types is associated with each age group(P < 0.05),inflammatory polyp gradually reduce with the increase of age,and adenoma detection rate increased with the increase of age.conclusion 1 The rate of CRC,colorectal polyps,MC has a tendency to increased with age,and the detection rate of male is significantly higher than female.2 UC detection rate ofyounger group is significantly higher than middle aged and elder group.And no significant difference between male and female could be seen.4 CRC cases is mainly with left half colon,check out the site associated with age,and rectal most,then the characteristics of the distal to the gradual development.5 In CRC cases,adenocarcinoma detection rate is the highest,followed by squamous cell carcinomas,signet ring cell carcinoma,myxoid carcinoma.Its clinical pathological types changes along with the age and gradually grow to adenocarcinoma.6 Colorectal polyps casesinthe rectum,sigmoid colon,the location of colorectal cancer is associated with age.7 Colorectal polyps most common pathological types are adenoma.Inflammatory polyp gradually decreased with increasing age,while adenoma detection rate increased with the increase of age.Pathological types of colorectal polyps are related to the check-out parts.Inflammatory polyp easily cases in rectum,followed by sigmoid colon.Adenoma cases in sigmoid colon most,followed by rectum,transverse colon. |
