| Objective: 1.Through the analysis of 12160 cases of colonoscopy data,explore the constitution and epidemiological characteristics of colorectal diseases in local citizens,and master the occurrence and development of colorectal diseases.2.Provide data for the screening of local colorectal diseases by analyzing the distribution characteristics of colorectal diseases and the factors affecting the detection rate of colorectal diseases.Provide a theoretical basis for the local health authorities to develop prevention and treatment measures for colorectal diseases,especially colorectal cancer.3.Summarize the experience of the rapid development of colonoscopy in the People's Hospital of North Jiangsu in recent years,and provide reference for other hospitals.Methods: A cross-sectional study was conducted to retrospectively analyze the colonoscopy data of 12160 patients in the Endoscopy Center of the People's Hospital of North Jiangsu from 2015.1.1 to 2016.12.31.1.Using the Excell table form,the colonoscopy data of the subjects included,colorectal cancer(again according to the patient's gender,patient age,intestinal segment),colorectal polyps(again according to patient gender,patient age,intestinal segment)The location,polyp number,polyp size,polyp pathological type grouping)and other common colorectal diseases(regrouped according to patient gender,patient age)grouped to establish a database.2.Calculate the detection rate(or ratio or composition ratio)of each intestinal disease and draw a histogram separately.3.Apply spss 25.0 software for statistical analysis,and use 2×2 or R×C to join the table card side test according to the data characteristics.The differences between groups and groups were compared,and the distribution characteristics of colorectal diseases were summarized.Result: There were 11 common colorectal diseases in the study.The three main diseases were: intestinal polyps,enteritis and colorectal cancer.The detection rates were 25.00%,7.64%,and 5.00%,respectively.82.78% of the total number of colorectal diseases;thedetection rate of different colorectal diseases is significantly different between males and females.The detection rate of intestinal polyps,colorectal cancer,intestinal diverticulum and intestinal schistosomiasis is higher than that of females,enteritis and ulceration.The detection rate of colitis and ischemic bowel disease was higher in women than in men,and the difference was statistically significant(P<0.05).Intestinal polyps are mainly distributed in the age range of 50-79 years old;enteritis is high in the18-29 age group;ulcerative colitis,erosive lesions,Crohn's disease often occur in the18-29 age group;colorectal melanosis,Ischemic bowel disease occurs frequently in the70-79 age group;the intestinal diverticulum is more common in the age group greater than 80 years old.The detection rate of colorectal cancer,intestinal polyps,intestinal diverticulum,ischemic bowel disease and intestinal schistosomiasis increased with age;the detection rate of enteritis and ulcerative colitis decreased with age.The total detection rate of colorectal cancer was 5.00%,of which rectal cancer accounted for the highest proportion of colorectal cancer(42.77%);from the distal to the proximal part of the intestine,the detection rate showed a decreasing trend.The detection rate of left intestinal cancer is much higher than that of the right side.The detection rate of colorectal cancer in different parts was higher in men than in women.The total detection rate of colorectal polyps was 25.00%.The detection rates of intestinal polyps in the young,middle-aged and elderly groups were 9.91%,23.90%,and 32.79%,respectively,showing an increasing trend.The detection rate of colorectal polyps in males of all age groups was higher than that in females,and the difference was statistically significant(P<0.05).The detection rate of different intestinal polyps was different,and the detection rate of sigmoid colon was the highest(26.69%),followed by rectum(21.13%),descending colon(17.31%),transverse colon(16.43%),and ascending colon(12.87%).The ileocecal department(5.58%).Adenomatous polyps accounted for the highest proportion of all colorectal polyps,increasing from younger group to middle-aged group to older group;the proportion of inflammatory polyps in all colorectal polyps decreased with age,three ages The groups were 48.95%,36.53%,and32.61%,respectively.In adenoma polyps,the detection rate of tubular adenomas wasthe highest,and the detection rate of villous adenomas was the lowest.The detection rate of non-adenomatous polyps in the young group was higher than that in the adenomatous polyps.The detection rate of adenomatous polyps in the middle-aged and elderly groups was higher than that in non-adenomatous polyps.With age,non-adenomas The proportion of polyps gradually decreased,and the proportion of adenomatous polyps gradually increased.The difference between the groups was statistically significant(P<0.05).Among the 3040 patients with colorectal polyps detected,1637 were single polyps and 1403 were polyps.The detection rate of single polyps in the young and middle-aged groups was higher than that in the polyps,while the rate of polyps in the elderly group was higher than that in the single-polyps.These differences were statistically significant(P<0.05).Colorectal polyps were divided into 4groups according to their size,of which 5-9mm polyps accounted for the highest proportion(47.22%),followed by less than 5mm group,and greater than 20 mm group had the lowest proportion of polyps(7.58%).There was no significant correlation between the size of colorectal polyps and the age of the patient,the gender of the patient,and the location of the intestine.As the diameter of colorectal polyps increased,the detection rate of non-adenomatous polyps gradually decreased,and the detection rate of adenomatous polyps gradually increased.Comparing the colonoscopy data of the hospital for nearly 7 years,the total number of mirrors is increasing every year.The detection rate of intestinal polyps is increasing year by year,and the detection rate of intestinal cancer is decreasing year by year.Conclusion: Intestinal polyps,enteritis and colorectal cancer are the three major intestinal diseases of the local public;the incidence of intestinal malignant diseases is positively correlated with age,and the incidence of enteritis is negatively correlated with age;left colon cancer and left colon gland The detection rate of neoplastic polyps was greater than that of the right colon,which was consistent with the adenoma-cancer sequence.From the proximal to the distal end of the intestine,the detection rate of colorectal cancer gradually increased;the adenomatous polyps were more than non-adenomatous polyps.Among the adenomatous polyps,the detection rate of tubularadenoma was the highest,and the detection rate of villous adenoma was the lowest;the detection rate of local intestinal polyps increased year by year,and the detection rate of colorectal cancer showed a downward trend.Male physicians,senior physicians,and painless colonoscopy showed a higher rate of polyp detection.Multivariate regression analysis showed that the age and gender of the patient,the sex and title of the examining physician,and whether or not to use painless examination were independent factors influencing the detection rate of intestinal polyps. |
