ABSTRACT
Objective To explore the detection rate of colorectal cancer by endoscopic,and study the value of digital rectal examination,fecal occult blood test,tumor markers examination,painless colonoscopy in colorectal cancer screening.Methods The data of 2 167 colonoscopy patients were retrospectively analyzed from January 2010 to December 2013.All the patients accomplished the digital rectal examination,fecal occult blood test,tumor markers examination before colonoscopy,the results were compared with pathology and surgical results.Results There was no statistical difference in the ratio of male and female in the year 2010-2013 (x2 =3.640 5,P ＞ 0.05).The detection rates of rectal adenoma in the year 2010-2013 were 4.762％ (25/525),8.180％ (40/489),8.276％ (48/580) and 8.028％ (46/573),there were no statistical differences (x2 =6.785 7,P ＞ 0.05).The detection rates of colorectal cancer in the year 2010-2013 were 12.571％ (66/525),11.656％ (57/489),13.448％ (78/580) and 10.820％ (62/573),there were statistical differences (x2 =2.065 7,P ＞ 0.05).The colorectal cancer accounts for the percentage of positive results of colonoscopy in the year 2010-2013 were 72.527％ (66/91),58.763％ (57/97),61.905％(78/126) and 57.407 ％ (62/108),there were statistical differences (x2 =5.679 8,P ＞ 0.05).Conclusions The detection rates of colorectal cancer are stable in the year 2010-2013.Combined with digital rectal examination,fecal occult blood test and tumor markers examination is the value of screening colonoscopy population,enhancing the pertinence,thus improving the colorectal cancer early diagnosis and early treatment levels.
ABSTRACT
Objective To explore the value of electronic colonoscope,MSCT and MRI in the etiological diagnosis of intestinal obstruction.Methods The clinical data of 140 ileus patients were retrospectively studied.Results 140 cases of ileus included 60 cases of colon ileus,70 cases of small intestines ileus and 7 indefinite cases.67 cases were checked with colonoscopy,among them,41 cases with colon tumors,6 cases with colon polypi,6 cases with colon set folds,2 cases with sigmoid colon turned round,2 cases with ileum tumor and 10 cases with unknown reason.80 cases were checked by MSCT checks,among them,26 cases with small intestines tumor 24 cases with small intestines muck piece,23 cases with unknown reasons,2 cases with muck stone 2,4 cases with bowel chamber outside lymphoid lump,1 case with bowel fastens film blood to bolt.30 cases were kept to cure.2 cases were turn round to reset under the eolonoscopy,3 cases were set folds air to infuse bowel to reset,6 cases with inside the mirror descend colon polyp were resected with hish frequency electricity resection.99 cases were cured by surgical operation.5 cases were dead and 135 cases were recovered from illness.Conclusion Electronic colonoscopy,MSCT and MRI checking are accurate methods to diagnose why and where of ileus,and which establish importance basts for clinical treatment.
