|Perioperative survival rates after surgery for diaphragmatic hernia in dogs and cats
Diaphragmatic hernias are common emergencies in small animal practices and clinics. Is it important to do surgery immediately or can this procedure become determined to a later time? The results of this study are clear: the chances are much better when the surgery is performed within 24 hours after admission - and this fact needs to be discussed with the owner of the affected animal...|
|This retrospective study on 63 dogs and 29 cats treated surgically for traumatic diaphragmatic hernia was performed to determine the survival rates of dogs and cats that underwent surgical treatment for traumatic diaphragmatic hernia within 24 hours of admission and determine whether timing of surgery affected perioperative survival rate.
Medical records were reviewed to evaluate associations between perioperative survival rates and variables including timing of surgery in relation to admission and acute versus chronic diaphragmatic hernia.
RESULTS: Among the 92 animals, 82 (89.1%) were discharged alive after surgery. Sixty-four (69.6%) patients received surgical intervention within 12 hours of admission, and 84 (91.3%) received surgical intervention within 24 hours of admission.
Median time from admission to discharge was 4 days (2 to 33 days).
Data for acute cases (68 dogs and cats) were analyzed separately.
Sixty-three (92.6%) patients with acute diaphragmatic hernia received surgical intervention within 24 hours of admission to the hospital, and 59 (93.7%) of these patients were discharged alive.
Twenty-nine (42.6%) patients with acute diaphragmatic hernia received surgical intervention within 24 hours of trauma, and 26 of 29 (89.7%) patients were discharged alive.
An overall acute and chronic perioperative survival rate of 89.7% was observed in dogs and cats that received surgical intervention within 24 hours of admission.
CONCLUSIONS AND CLINICAL RELEVANCE: Results in 68 dogs and cats that underwent surgery within 24 hours of admission suggested that early surgical intervention for acute diaphragmatic hernia was associated with good perioperative survival rates.
