Study highlights laparoscopic repair for PPDH in dogs and cats

Version 1

A new multicenter case series in Veterinary Surgery suggests laparoscopic repair may be a practical minimally invasive option for selected dogs and cats with peritoneopericardial diaphragmatic hernia, or PPDH. In 13 patients — 12 dogs and one cat — surgeons used low-pressure CO2 insufflation to repair the defect, with successful laparoscopic completion in 92% of cases and no serious complications reported. The report is notable because standard guidance for congenital diaphragmatic hernias, including PPDH, has traditionally centered on open surgical repair through a ventral midline celiotomy.

Why it matters: For veterinary surgeons and referral teams, the study adds early multicenter clinical data supporting a less invasive approach to a condition that is often incidental, but can still cause respiratory, gastrointestinal, or cardiovascular compromise. PPDH is a congenital defect in dogs and cats, and surgery remains the definitive treatment when intervention is indicated. If laparoscopic repair proves reproducible in broader practice, it could expand options for case selection, perioperative planning, and client conversations with pet parents who are weighing referral for minimally invasive surgery.

What to watch: The next question is whether larger comparative studies can show where laparoscopy offers clear advantages over open repair in operative time, complications, recovery, and case selection. (pubmed.ncbi.nlm.nih.gov)
