Original publication title: Retrospective evaluation on the outcome of perineal herniorrhaphy augmented with porcine small intestinal submucosa in dogs and cats.
Plain-English summary
A group of 11 dogs and 3 cats with perineal hernias underwent surgery to repair the condition, using either a special tissue from pigs (porcine small intestinal submucosa) alone or in combination with a muscle repositioning technique. After surgery, one pet developed an infection, and some animals experienced complications, but overall, the surgeries were considered successful. Out of the 21 hernias treated, only 3 came back after surgery. Both methods of repair were deemed acceptable, especially if there were concerns about the muscle's strength.

Abstract
The purpose of this study was to evaluate post-operative outcome in dogs and cats undergoing perineal herniorrhaphy using porcine small intestinal submucosa (PSIS) alone and with internal obturator muscle transposition augmented with PSIS (IOMT + PSIS). Medical records were retrospectively reviewed and information collected on signalment, pre-operative signs, operative details, and hospitalization. Data on post-operative outcome were obtained from medical records and survey. Eleven dogs and 3 cats had 18 perineal hernias repaired with IOMT + PSIS and 3 using PSIS alone. Surgical site infection developed following IOMT + PSIS in 1/21 hernias (5.6%). Short- and long-term postoperative complications occurred in 9/14 animals and 3/14 animals, respectively. Among the 21 perineal hernias, 3 recurred, 2 of which were repaired with IOMT + PSIS and 1 with PSIS alone. Use of PSIS alone or augmenting IOMT was acceptable for perineal herniorrhaphy and should be considered by surgeons if there are concerns about internal obturator muscle integrity.
