A simplified technique for laparoscopic gastropexy (group 1) was compared to belt-loop gastropexy (group 2) in eight adult male dogs randomly divided into two groups of four dogs each. Our hypothesis was that a satisfactory laparoscopic gastropexy would approximate the strength and operative time required for belt-loop gastropexy. Operative time, surgical complications, postoperative morbidity, gross and histological appearance, radiographic microvascularization, and maximal tensile strength were measured and compared between the two groups. All dogs recovered from surgery. No morbidity was associated with either procedure. The mean (+/- SD) duration of surgery was 69.75 +/- 7.23 minutes for group 1 and 58.75 +/- 7.63 minutes for group 2. Fifty days after surgery, the microvascular appearance of the gastropexy site was similar for both groups. Blood vessels were observed within each seromuscular flap but vascular ingrowth to the abdominal musculature was observed in only two dogs, one from each group. The maximum tensile strength at 50 days was 76.55 +/- 22.78 for group 1 and 109.21 +/- 22.29 N for group 2. Differences between surgical duration and maximum tensile strength were not statistically significant (P > .05). Histologically, all gastropexies consisted of an adhesion composed of dense fibrous connective tissue. The results of this study indicate that laparoscopic gastropexy provides a minimally invasive alternative to open abdominal prophylactic gastropexy in dogs.

Thoracolumbar intervertebral disc disease is the most common cause of caudal paresis in dogs. Whilst the pathogenesis of the extrusion has been widely studied, treatment protocols and prognostic factors relating to outcome remain controversial. Recent studies have examined a multitude of factors relating to time to regain ambulation after decompressive surgery. Most intervertebral disc herniations occur in the thoracolumbar region, causing upper motor neuron signs in the rear limbs, which are thought to have a more favourable prognosis compared to the lower motor neuron signs created by herniation of an intervertebral disc in the caudal lumbar region. Due to the potential disruption of the lumbar intumescence, lower motor neuron signs have been reported as having a less favourable prognosis. The purpose of this study was to evaluate the intervertebral disc space as a prognostic factor relating to ambulatory outcome and time to ambulation after decompressive surgery. Hansen Type I intervertebral disc extrusions were studied in 308 non-ambulatory dogs. Preoperative and postoperative neurological status, corticosteroid use, signalment, intervertebral disc space, postoperative physical rehabilitation, previous hemilaminectomy surgery, disc fenestration, return to ambulation, and time to ambulation were reviewed.

Our study evaluated thigh circumference (TC), stifle range of motion (ROM), and lameness in dogs one to five years after unilateral tibial plateau levelling osteotomy (TPLO). We hypothesised that TC, stifle ROM, and lameness would not be different to the unoperated limb (control), one to five years after surgery. Patients that were one to five years post-TPLO were reviewed and were included if they had a unilateral TPLO, and no additional clinical evidence of orthopaedic disease. Standing mid-thigh TC measurements and stifle extension and flexion angles were made in triplicate. Clinical lameness was graded blindly. Data were evaluated statistically using paired t-tests for TC and stifle flexion and extension. Significance was set at p <0.05. Twenty-nine dogs met the inclusion criteria. Mean results for the surgery limbs and control limbs were 39.5 +/- 5.5 cm and 40.1 +/- 5.6 cm for TC, 36.6 +/- 6.8 degrees and 28.6 +/- 4.3 degrees for stifle flexion, and 155.2 +/- 6.6 degrees and 159.8 +/- 4.9 degrees for stifle extension, respectively. The mean TC for the operated limb was 98.5% of the control limb. A significant difference was found between the operated and the control limbs for all measurements. Time after surgery had no apparent affect on outcome. Four of 29 dogs (14%) exhibited some lameness in the TLPO limb during evaluation (one dog was 1 to 2 years postoperative and three dogs were 2 to 3 years postoperative). These results indicate that TC and stifle ROM in the TLPO limb do not return to control-limb measurements one to five years after a TPLO surgery. The clinical significance is unknown as TC returned to 98.5% of control, and the source of lameness in the lame dogs was not identified.

Long digital extensor tendon avulsion is reported in a 5 month old Great Dane. Clinically the dog presented with a unilateral weight-bearing pelvic limb lameness. Joint effusion was present and there was pain and crepitance associated with flexion of the stifle. Orthopedic evaluation and radiographs were suggestive of a long digital extensor tendon injury which was confirmed by computed tomography and magnetic resonance imaging. The injury was surgically repaired with screw and spiked washer fixation.

Summary A technique is described which is particularly useful in obese or heavily muscled animals when a single lumen tracheostomy tube is used, or when mechanical ventilation through a cuffed tracheostomy tube is required. The technique assures easy access to a large tracheal stoma which facilitates cleaning and tube replacement.
