The Reason of Delay in the Diagnosis of Right Side Colon Cancer

Objective: It can often be seen that the d iagnosis of right side colon cancer is delayed. How can we avoid it?Methods:The histories of the patients who were diagnosed as righ t side colon cancer by colonoscopy in our hospital were reviewed retrospectively . We find the diagnosis of 32 patients was delayed for many reasons. Results: 9 cases were misdiagnosed as acute appendicitis, 5 case s as chronic appendicitis, 6 cases as appendicular abscess, 2 cases as anemia, 2 cases as intestinal obstruction, 2 cases as chronic colitis, one case as duoden al ulcer and one case as chronic cholecystitis. 2 cases with right side colon ca ncer weren't found in barium enema as well as 2 cases in colonoscopy. Conclusion:Patients with right abdominal pain, mass, hematochezi a and anemia should be considered as right side colon cancer and further diagnos tic examinations, especially barium enema and colonoscopy, are necessary. These examinations should be repeated when the patients are clinically considered as c olon cancer but the examinations are negative.
