Endoscopic rectal ultrasound in staging of rectal carcinoma. Comparison with patohistological postoperative diagnose. Can the surgeon rely on a finding of an endoscopist before deciding on the type of surgical procedure?

Background: A number of patients who are suffernig from colorectal cancer is increasing worldwide. This study attempted to demonstrate the benefit of endoscopic rectal ultrasound scan (ERUS) of anorectal area in patients with cancer on decision for therapeutic approach and type of surgical procedure. Aldo, we compared ERUS with postoperative pathohistological tumor staging. Methods: In 40 patients with endoscopyc and pathohistological (PH) diagnosis of rectal cancer ERUS was performed to determine the extent of the disease, which was subsequently compared with postoperative pathohistological findings. 26 patienst continue the study. Results: After ERUS examination, there where three responders in group Tis (T0), five in group T1, twelve in group T2, seventeen in group T3, two in group T4 and one of responders had extraluminal carcinoma. After selection within patients, we compared 26 ERUS findings with pathohistological diagnosis, to determine sensitivity and accuracy of ERUS. Patients who provided chemoteraphy and irradiation procol before surgery were excluded from study. The total sensitivity of the ERUS in preoperative staging, for tumor in stage T0-T4 was 96%. Accuracy was 89%. Conclusions: This research has shown that the surgeon can rely on a finding of an endoscopist before deciding of type of surgical procedure for T0-T2, and even T3 staging rectal cancer. This does not minimize the importance of magnetic resonance imaging (MRI), but simplifies the procedure for the patient. MRI would remain the gold standard for T4 staging of rectal cancer.
