“…In the present study, the age group ranged from 25 to 80 years. Most of the studies[ 11 12 13 15 17 18 ] reported male predominance, which was in concordance with the present study where males (20, 65%) were more commonly involved as compared to females (11, 35%). In a study done by Khanbhai et al ., 2014, preoperative anemia was observed in 88 (44%) patients with mean hemoglobin levels below the lower limit of normal for that sex, whereas in the present study, anemia was found in 11 (35%) patients; however, it was normal in twenty patients.…”

“…[ 15 ] The sensitivity of the nodal detection in studies done by Okizuka et al ., 1995, was 60%. [ 12 ] In the present study, enlarged lymph nodes were found in 14 (45%) cases of a total of 31 patients. Pericolic/perirectal fat stranding was present in 24 cases (77%) of bowel malignancies and was absent in 7 cases (23%).…”

Background:The staging of colorectal carcinoma using 3 modalities viz operative, histopathology and CT scan has been subject of interest in accurately defining the extent of disease. This retrospective as well as prospective study was carried out at CMC, Ludhiana, Punjab from November 2011 to May 2014.Aim:The objective of this study was to assess the usefulness and accuracy of CT scan findings to state the extent and spread of colorectal malignancy and to correlate these findings with histopathological diagnosis.Method:A total of 31 biopsy proven patients showing variable bowel wall thickening involving the colon /rectum on CECT (Contrast Enhanced Computed Tomography) were included in the study. The tumours were staged based on the CT scan findings and were compared with the operative and histopathological findings.Observations:Rectum was the most common site of involvement followed by the recto-sigmoid involvement. Metastasis was observed in 5 cases out of the 31 malignant cases. Five of the 7 cases were correctly staged as T1 & T2 lesions on CT having a sensitivity of 83.3%, specificity of 92%, and positive predictive value of 71.4% and a negative predictive value of 95.8% in the diagnosis of T1 and T2 lesions. 15 of the 16 cases were correctly staged as T3 lesions. CT had a sensitivity of 88.2%, specificity of 93.8%, and positive predictive value of 93.8% and a negative predictive value of 86.7% in the diagnosis of T3 lesions. All the 8 cases were correctly staged as T4 lesions. CT had a sensitivity of 100%, specificity of 100%, and positive predictive value of 100% and a negative predictive value of 100% in the diagnosis of T4 lesions.Conclusion:We conclude that CT scan is an excellent modality in diagnosing malignant lesions of the colon and rectum.

Objective: To compare high-frequency transabdominal ultrasonography (USG) and spiral computed tomography (CT) with colonoscopy in diagnosis of colon cancer. Design: A prospective comparative study of accuracy of USG and CT scan with colonoscopy. Subjects: Sixty patients with a clinical suspicion of colon cancer after a detailed clinical history and a thorough clinical examination were included. Patients with a known diagnosis of colon cancer or in whom histopathological diagnosis could not be established were excluded. Methods: All 60 patients who met the inclusion and exclusion criteria underwent transabdominal USG, CT scan-abdomen & pelvis, followed by colonoscopy. The CT and USG scans were reported by different radiologists without previous knowledge of any findingsof the other test or of the subsequent colonoscopy. The colonoscopy was performed by different clinicians, none of whom was aware of the USG or CT diagnosis. Result: Colonoscopy diagnosed 29 patients with colon cancer out of 60 enrolled patients. USG detected colon cancer in all the 29 patients with a sensitivity of 100% and a specificity of 87.1%. CT scan diagnosed colon cancer in all the 29 patients with a sensitivity of 100% and a specificity of 74.2%. Conclusions: Colonoscopy is still necessary when a suspicious lesion is identified. However, CT and USG can screen out suspected patients who can be subsequently referred for colonoscopy. This would reduce the need for colonoscopy in a large proportion of clinically suspected patients andalso avoidan invasive procedure like colonoscopy as first line investigation in elderly patients suspected of having colonic cancer.
