Case Report: Fascia lata transposition for chronic recurrent perineal hernia followed by laparoscopic colopexy for subsequent rectal prolapse in a dog.

This case report describes a surgical management of chronic, recurrent, complicated perineal hernia following bilateral herniorrhaphy in a 6-kg castrated male mixed-breed dog, estimated to be over 10 years old. The patient presented with recurrent right-sided perineal hernia and constipation associated with rectal sacculation. During the herniorrhaphy attempted, severe atrophy of pelvic musculature was identified; therefore, a fascia lata transposition was performed. Postoperatively, the dog developed a rectal prolapse, which was successfully addressed through laparoscopic colopexy. The dog recovered uneventfully, maintaining a good appetite and activity levels. There were no complications related to urination, defecation, gait, or wound healing following either procedure. At the 27-month follow-up, the dog remained in good condition without clinical signs. Fascia lata transposition is effective for complicated perineal hernias lacking of musculature for reconstruction. Laparoscopic colopexy is also a clinically practical option for rectal prolapse in small-breed dogs.
