Local recurrence, Rectal cancer, Ultrasonography
The ultrasonic findings obtained in a patient with recurrent rectal carcinoma are presented. A 67-year-old man was admitted because of perineal pain. Total gastrectomy with partial pancreaticosplenectomy and abdominoperineal resection of the rectum because of the gastric and the rectal cancer about one year ago. Carcinoembryogenic antigen (CEA) was 31.3 ng/ml and it definitely suggested recurrence of the rectal cancer. Ultrasonic examination of the pelvic space with the fulfilled urinary bladder in the prone position from the perineum revealed a tumor mass between the bladder and the perineum sized 95 by 45 mm with the irregular shaped margin. Pelvic exenteration with partial resection of the sacrum was done. We believe that ultrasonography is useful in the follow up after the resection of rectal cancer for early detection of local recurrence.
