Abstract

Objective—To describe clinical and physiologic changes during lift laparoscopy in dogs and cats and determine immediate surgical outcome.

Design—Retrospective case series.

Animals—Client-owned dogs (n = 7) and cats (5).

Procedures—A custom-made lift device was used to retract the abdominal wall for laparoscopic instrumentation. The lift device was used first in 3 dog cadavers to assess the risk of complications. Thereafter, the device was used for routine laparoscopic procedures in client-owned animals. Data collected from medical records included signalment, body weight, clinical signs, diagnosis, surgery type and duration, conversion from laparoscopic to open surgery, preoperative American Society of Anesthesiologists score, mean intraoperative respiratory rate, mean and peak end-tidal partial pressure of CO2 during the laparoscopic surgery, ventilation method, mean saturation of hemoglobin with O2, mean and systolic arterial pressures during the laparoscopic surgery, total anesthesia time, signs of pain immediately after recovery, duration of hospitalization, and postoperative complications.

Results—Lift laparoscopy was successfully performed in 10 of the 12 patients. No adverse effects were noted with the use of this technique. However, in 1 dog and 1 cat, conversion to laparotomy was necessary because of poor visualization.

Conclusions and Clinical Relevance—Results suggested that lift laparoscopy is feasible in dogs and cats and is an option that can be used in clinical practice, especially if creation of positive-pressure pneumoperitoneum is not desirable.

Abstract

CASE DESCRIPTION 2 fillies, aged 3 months and 1 month, were examined because of urinary incontinence and urine scalding.

CLINICAL FINDINGS In horse 1, ultrasonography did not reveal any structural abnormalities of the kidneys; however, unilateral ureteral ectopia was diagnosed cystoscopically. In horse 2, CT revealed bilateral nephropathy, bilateral distended ureters (up to 3.6 cm in diameter), and bilateral ureteral ectopia. Cystoscopy revealed intramural ureteral ectopia with abnormally caudally positioned ureteral ostia in both horses.

TREATMENT AND OUTCOME Ureteral ostioplasty was performed under cystoscopic guidance. Laparoscopic scissors (horse 1) or a vessel-sealing device (horse 2) was introduced, and the tissue separating the intramural portion of the ureter from the urethra and bladder was cut longitudinally in a cranial direction toward the trigone. After surgery, both horses were continent and voided normal streams of urine for the duration of the follow-up periods of 20 and 9 months for horse 1 and horse 2, respectively.

CLINICAL RELEVANCE Cystoscopically guided ureteral ostioplasty provided an effective and minimally invasive surgical treatment option for correction of ureteral ectopia in 2 fillies.

Abstract

Objective—To determine whether scores for basic laparoscopic skills were significantly associated with extent of laparoscopic experience and compare basic laparoscopic skill scores obtained before and after 2 laparoscopic training sessions incorporating a canine abdominal model.

Design—Evaluation study.

Sample Population—8 experienced and 25 novice individuals.

Procedures—Novice participants were randomly assigned to control (n = 10) and training (15) groups. Individuals in the experienced and novice training groups were required to undergo 2 training sessions with a canine abdominal model. Basic laparoscopic skills were assessed twice on the basis of 3 tasks included in the McGill Inanimate Simulator for Training and Evaluation of Laparoscopic Skills (MISTELS).

Results—For the novice training group, laparoscopic skills scores were significantly higher after training than before, but for individuals in the novice control group, scores did not differ significantly between the first and second assessments. The increase in score for the novice training group was significantly higher than increases for the experienced group and for the novice control group, but the increase in score for the experienced group was not significantly different from the increase in score for the novice control group.

Conclusions and Clinical Relevance—Results suggested that basic laparoscopic skills scores obtained with the MISTELS were associated with extent of laparoscopic experience and that training with a canine abdominal model could increase skills scores for individuals without previous laparoscopic experience.

Abstract

Case Description—An 18-year-old Paint stallion (horse 1) and a 17-year-old Morgan gelding (horse 2) were evaluated because of an acute onset of severe unilateral forelimb lameness.

Clinical Findings—Both horses were unable to bear weight on the affected forelimb and had a dropped elbow appearance. Radial nerve paralysis, triceps myopathy, and fractures of the humerus and ulna were ruled out. The caudal aspect of the affected antebrachium of each horse was very firm to palpation and became firmer when weight was shifted onto the limb. Ultrasonographic examination revealed swelling and suspected intramuscular hemorrhage of the caudal antebrachial muscles. On the basis of clinical examination and diagnostic imaging findings, both horses had antebrachial compartment syndrome diagnosed. Lameness did not substantially improve with medical treatment in either horse.

Treatment and Outcome—Caudal antebrachial fasciotomy was performed in each horse. Following sedation and local anesthetic administration, a bistoury knife was inserted through small incisions to perform fasciotomy. Horses remained standing throughout the procedure and were immediately able to bear weight on the affected limb without signs of discomfort. Horse 1 developed colitis and horse 2 developed a mild incisional infection, but both fully recovered and returned to their previous activities.

Clinical Relevance—Antebrachial compartment syndrome is a rare cause of severe unilateral forelimb lameness and should be considered as a differential diagnosis in horses with a dropped elbow appearance. Both horses of this report had a successful outcome following antebrachial fasciotomy.
