Disposable skin staplers for closure of linear gastrointestinal incisions in dogs.

OBJECTIVE: To report the clinical features and outcomes of linear gastrointestinal incisions closed with skin staples in dogs. STUDY DESIGN: Historical cohort study. ANIMALS: 333 client-owned dogs. METHODS: Medical records from 1 private referral hospital were searched for dogs that underwent gastrointestinal surgery between November 1999 and October 2015. Cases were included if skin staplers were used to close linear gastrointestinal incisions. Information regarding preoperative, surgical, and postoperative factors was collected. RESULTS: Complications were diagnosed in 8 of 245 (3.27%) dogs, including 3 of 245 (1.22%) dogs that died or were euthanized, 3 of 245 (1.22%) dogs with incisional dehiscence, and 2 of 245 (0.81%) dogs with attachment of a linear foreign body to the staples at the intestinal lumen. Dehiscence was noted at the enterotomy sites in 3 dogs at a mean time of 44 hours after surgery (SD ± 6.93). Two dogs presented with another linear foreign body that was attached to the staples in the intestinal lumen at postoperative days 24 and 42. The risk factors associated with incisional dehiscence included multiple gastrointestinal incisions performed in 1 surgery (χ2 , P < .001) and the presence of a linear foreign body (χ2 , P = .02253). No associations were detected between dogs' age, sex, weight, surgery time, indication for surgical intervention, surgery location in the gastrointestinal tract, or surgeon experience and incisional dehiscence. CONCLUSION: Skin staplers provide safe and effective closure of gastrotomies, enterotomies, and colonotomies in dogs. This method is reliable, efficient, and affordable in the hands of veterinary surgeons with varying skill levels.

Atlantoaxial subluxation in two dogs with cervical block vertebrae.

Atlantoaxial (AA) subluxation is an uncommon disorder that can cause various degrees of neurological deficits in dogs. Block vertebra is a congenital deformation involving the fusion of two or more vertebrae. This report describes two dogs with cervical block vertebrae from C(2) to C(5) and C(2) to C(4), respectively. We hypothesize that the fused cervical vertebrae created a "fulcrum effect" at the AA joint and predisposed these dogs to traumatic AA subluxation.
