Abstract

OBJECTIVE

To describe the intestinal full-thickness needle-core biopsy technique via abdominal laparotomy outcomes and compare the histopathological and immunohistochemical diagnosis with standard incisional intestinal biopsy technique in dogs and cats.

ANIMALS

3 dogs and 17 cats.

METHODS

Client-owned dogs and cats were prospectively enrolled if intestinal full-thickness biopsies were indicated for the diagnosis of diffuse chronic intestinal diseases following ultrasonography. The study period extended from June 2021 to December 2022. All animals underwent intestinal biopsies with both techniques (needle-core biopsy and standard incisional biopsy) via abdominal laparotomy. Data collected included clinical signs, biopsy collection times, complications, and histopathologic and immunohistochemical findings. A minimum follow-up of 14 days was required.

RESULTS

The main clinical sign at presentation was chronic vomiting (65%). Mean needle-core biopsy collection time (262 seconds) was significantly shorter than standard incisional biopsy collection time (599 seconds; P < .000001). The incidence of minor complications was 10% (inflammation of the skin surgical site secondary to licking). One catastrophic complication occurred on a standard incisional biopsy site in 1 cat in a context of bile peritonitis (5% of all cases). There were no complications associated with the needle-core biopsy. All but 1 cat were discharged, with a median of 2 days (range, 1 to 4 days) after surgery. The diagnoses resulting from both techniques were 100% concordant for the distinction between inflammatory bowel disease and intestinal lymphoma via histopathology and immunochemistry.

CLINICAL RELEVANCE

Needle-core biopsy is safe, rapid, and effective and is less invasive than standard incisional biopsy.

Abstract

OBJECTIVE

To report indications, outcomes, and complications with a precontoured angle-stable interlocking nail (CAS-ILN).

ANIMALS

90 client-owned animals.

METHODS

Dogs and cats treated with the CAS-ILN between 2020 and 2022 were retrospectively reviewed. Collected data included body weight, fracture configuration, percentage of medullary canal filled, limb alignment, complications, and follow-up. Favorable outcomes were defined when full functional restoration was observed.

RESULTS

Thirty-eight dogs and 52 cats were included. Median body weight was 4.3 kg (range, 1.5 to 6.7 kg) for cats and 25 kg (range, 6.8 to 54 kg) for dogs. A total of 54 femurs, 31 tibias, and 5 humeri were treated, including 65 comminuted fractures and 26 metaphyseal fractures. The median percentage of medullary canal occupied by the nail was 76.5% (range, 53% to 97.6%). Radiographic postoperative bone alignment was good in 85.5% (59/69) and satisfactory in 10 cases. The median duration of follow-up (57/90) was 476 days (range, 56 to 1,057 days). In the perioperative period (0 to 12 weeks), lameness had resolved or was mild in all (51/52) but 1 case. In the long-term postoperative period (> 12 months), 97.1% (34/35) of cases showed restoration of full function and 1 case had an unacceptable function. An overall complication rate of 11.5% (7/61) was reported including 1 catastrophic and 6 major complications.

CLINICAL RELEVANCE

Long-term functional outcomes following the CAS-ILN were favorable in 97.1% (34/35) of cases. Complication rates were comparable to previous studies. The CAS-ILN appears to be an alternative surgical option for most long-bone fracture repairs.
