Celiotomy and gastrotomy for surgical removal of foreign bodies in axolotl (Ambystoma mexicanum) – case report

Abstract

The ingestion of foreign bodies in artificial aquariums is a frequent occurrence observed in the surgical clinic of amphibians raised as pets, which includes axolotls (Ambystoma mexicanum). The present report describes a case of ingestion of seven foreign bodies in a male axolotl, five months old, with a history of irregular and irreducible bulging of the ventral body surface, with firm consistency. In the anamnesis, it was reported that the animal inhabited an aquariums with gravel substrate. On physical examination, the axolotl showed good general condition and vital parameters within the normal range for the species. The swallowed materials were identified in the gastric region by means of total body radiographic examination, and their characteristics were consistent with the substrate used in the patient’s aquarium. As anesthetic protocol, immersion in Isofluorane and oxygen gas was prioritized, in order to reach the branchial and, occasionally, transdermal route. Surgical removal was performed through celiotomy and gastrotomy in an aquatic environment with controlled temperature, pH and bacterial collection, according to available literature and taking into account the nature, diameter and location of foreign bodies. After five and fifteen days of the procedure, the healing of the surgical wound was monitored, showing a good restoration of tissue continuity and a good general condition of the patient.
