Laparoscopic peritoneopericardial herniorrhaphy in 2 dogs.

Two peritoneopericardial hernias (PPDH) repaired laparoscopically are reported. Both PPDHs were approached with the dog in dorsal recumbency. Herniated organs (gallbladder and 2 liver lobes in Case 1 and omental fat in Case 2) were dissected and reduced. Hernias were closed in a 2-layer horizontal mattress pattern using 2-0 polyester (Case 1), and in a single-layer simple continuous pattern using 0 barbed polyglyconate (Case 2). Reduction and herniorrhaphy were achieved without conversion. Moderate to severe systemic hypotension was observed in both dogs which responded rapidly to reducing abdominal insufflation. Ten- and 7-month follow-up confirmed good clinical outcome in both dogs.
