Original publication title: Obturator-Assisted Prolapse for Access to and Sampling of Colorectal Masses in Seven Dogs.
- Species:
- dog
Plain-English summary
Seven dogs with colorectal masses were diagnosed using a new technique called obturator-assisted prolapse, which allowed veterinarians to access and take samples from the masses without traditional surgery or endoscopy. This method was used after the masses were found during physical exams and CT scans. All dogs received adequate tissue samples for diagnosis, which helped plan their treatment, and there were no major complications reported in the months following the procedure. This approach could be a helpful option when standard methods are not possible.

Abstract
The gold standard for diagnosis of colorectal masses is surgical biopsy; however, this is not always logistically or economically feasible. The authors present an alternative to established flexible and rigid endoscopic approaches when case limitations require such an approach. In seven dogs, after the identification of a mass on physical exam and computed tomographic evaluation, the colorectum was accessed using obturator-assisted prolapse to isolate discrete masses and perform shielded sampling via core needle biopsy. Histopathologic diagnosis was adequate for treatment planning in all dogs. No major complications were recorded 65-475 days after the procedure. This technique may be useful when traditional endoscopy and surgery for biopsy of colorectal masses is unavailable.
