title: [Computerized tomography and sonography in the diagnosis of recurrent colorectal tumors].
abstract: CT and ultrasound of the abdomen were retrospectively evaluated in 44 patients operated on colorectal cancers (18 colon, 26 rectal carcinomas) in detecting a recurrence suspected on biochemical, endoscopic or clinical grounds. CT is superior to ultrasound in detecting a recurrence (metastases of liver and lymph nodes, local recurrence, intra-abdominal recurrence of another localisation). CT is recommended as a routine examination in the follow-up of patients operated on colorectal cancers.
