Rectal mesenteric metastasis from prostate cancer treated with adjunctive hydrodissection during cryoablation.

Abstract

Abstract: Cryoablation is a safe and promising technique for patients with solid tumors. However, when adjacent to vulnerable structures, appropriate protective measures are necessary while carrying out this procedure. Herein, we present a case of a prostate cancer patient with rectal mesenteric metastasis who underwent cryoablation. The lesion was separated from the rectum by hydrodissection. No grade II-IV adverse events were encountered intraoperatively, and dramatic improvements in the stool were observed. These findings indicate that cryoablation combined with hydrodissection is a safe and reliable treatment method for lesions adjacent to the rectum.
