Abstract

The surgical methods for treatment of adenomatous polyps in dogs and their effectiveness for maintaining health and quality of life of the animal were studied. The study was conducted on the clinical case of colorectal tubular adenoma (TA) surgical treatment in a 11-year-old male Irish setter who was admitted for hematochezia. A colonoscopy revealed a colon wall neoplasm. Based on the data of cytological and histological examination of the biopsy material, the patient was diagnosed with tubular adenoma of the rectum. Computed tomography revealed a mass 5718.318.3 mm in the rectal ampoule. After tissue segmentation, to make a therapeutic decision about the possibility of surgical resection and access, the ampoule of the rectum was resected through dorsal access. In the early postoperative period, tenesmus (with a decrease in their severity within a week after surgery) and partial fecal incontinence were recorded. The most serious complication was the formation of several more defects of the colon wall cranially from the superimposed anastomoses, which required three more operations. To decompress the colorectal anastomosis, a temporary flank double-barrelled colostomy with a support bridge was performed. The study revealed that despite the relatively rare incidence of TA in dogs, the comparison investigation of diagnosis and surgical treatment methods and avoiding postoperative complications and tumor recurrence is a relevant task both due to the possibility of TA malignancy and due to the fact that dogs are a naturally biological model for investigating this pathology.
