Urinary calculi associated with portosystemic shunts in six dogs.
Portosystemic shunts were diagnosed in 6 dogs with urinary calculi and signs of neurologic disease. Five of the dogs were initially examined because of neurologic signs, and 1 was seen because of urinary tract problems. The composition of the calculi was variable, but in all 13 episodes of calculi formation, the calculi contained an ammonium or uric acid component. One dog is being controlled under medical management; 4 of the dogs died, and 1 was euthanatized. The interpretation of pathogenesis was that decreased delivery of blood to the liver due to shunting or decreased liver function can potentially result in high blood concentrations of ammonia and uric acid, both of which are metabolic end products cleared by the kidneys; thus, the urinary tract would be an excellent environment for the precipitation of their salts.

Results of partial mandibulectomy for the treatment of oral tumors in 142 dogs.
Partial mandibulectomy was performed for the treatment of benign or malignant oral tumors in 142 dogs. Forty-two dogs with a benign tumor (ameloblastoma) had a 22.5 month (range, 6 to 74 months) median disease-free interval, with a 97% 1-year survival rate; there was local recurrence in one dog. Twenty-four dogs with squamous cell carcinoma had a disease-free interval of 26 months (range, 6 to 84 months), with a 91% 1-year survival rate; recurrence and metastasis developed in two dogs and metastatic disease in one dog. Based on survival curves, 37 dogs with a melanoma had a median survival time of 9.9 months (range, 1 to 36 months), with a 21% 1-year survival rate; 20 dogs died or were euthanatized for recurrent or metastatic disease. Twenty dogs with osteosarcoma had a median survival time of 13.6 months (range, 3 to 28 months), with a 35% 1-year survival rate; nine dogs died or were euthanatized for recurrent or metastatic disease. Nineteen dogs with fibrosarcoma had median survival time of 10.6 months (range, 3 to 32 months), with a 50% 1-year survival rate; 12 dogs died or were euthanatized for recurrent or metastatic disease. Results of this and previous studies demonstrated that partial mandibulectomy was effective in prolonging survival and decreasing recurrence for squamous cell carcinoma and ameloblastoma. Progressive disease and corresponding low survival times were common in dogs with melanoma, osteosarcoma, and fibrosarcoma. There were no differences in survival times or the progression of disease among five partial hemimandibulectomy procedures. The high rates of recurrence and metastasis in dogs with these tumors suggest a need for evaluation of ancillary chemotherapy and local radiation therapy to decrease the prevalence of progressive disease.

Dental composite for the fixation of mandibular fractures and luxations in 11 cats and 6 dogs.
Twenty-one mandibular fractures in 11 cats and 6 dogs were repaired during a 20-month period. A new technique using dental composite was used to stabilize the mandible. The canine teeth were pumiced, acid etched, and aligned with dental composite, leaving the mouth opened approximately 1 cm. Six weeks after surgery the composite was removed so that radiographs of the mandible could be made with the animal under general anesthesia. In 1 dog in which the fracture had not healed, the composite was replaced. The composite broke before 6 weeks in 8 animals; 2 required replacement of the dental composite. There were no other complications. The median time for fracture healing was 6 weeks. All fractures healed with anatomic dental occlusion. The advantages of this technique are that no further damage is caused to the teeth or to the blood supply of the bone, the occlusion is anatomic, dermatitis (which is seen with tape muzzles) is not a complication, and the technique is easy to use in brachycephalic breeds, cats, and animals with poor bone quality. The limiting factor of this technique is that it does require four salvageable canine teeth. This repair technique is still a viable option even if one or more of the canine teeth are fractured. Dental composite stabilization is fast, easy, inexpensive, and, in our series, it was 100% effective for the repair of mandibular fractures.

Comparison of seven different suture materials in the feline oral cavity.
Seven different suture materials were implanted into the oral tissues of 12 cats. The sutures and surrounding tissues were retrieved en bloc from each of two cats on days one, three, seven, 14, 21, and 28 postimplantation. Tissue reaction and suture duration were evaluated by gross visual observation and histological examination. Chromic gut disappeared between days three and seven; polyglactin 910 disappeared between days 14 and 21; and polyglycolic acid disappeared as early as seven to 14 days. Polydioxanone still was intact at day 28 and is recommended as an absorbable material for procedures in which longer healing time is anticipated. All the nonabsorbable suture materials (i.e., polypropylene, stainless steel, and nylon) were intact at day 28 postimplantation. Visual inspection showed polypropylene to have the least tissue reaction.

Ophthalmic manifestations and complications of dental disease in dogs and cats.
Ophthalmic manifestations of dental disease may occur in dogs and cats because of the proximity between posterior maxillary teeth and the orbit. Ophthalmic disorders may be diagnosed promptly, but the initiating dental disease may be overlooked. Inappropriate diagnosis and treatment of dental disease may result in loss of teeth, irreversible vision-threatening ophthalmic disease, or, ultimately, loss of the globe. When ophthalmic examination results are suggestive of a primary dental disorder, thorough examination of the maxillary teeth is imperative to diagnose appropriately the underlying dental disease. Therapy should include treatment of the dental disease and secondary ophthalmic disorders.

Choanal atresia and secondary nasopharyngeal stenosis in a dog.
A 20-month-old, intact male shih tzu was evaluated for chronic upper airway disease. Endoscopic examination established a diagnosis of choanal atresia, a developmental anomaly of the posterior nasal cavity. Although surgical intervention provided temporary relief, stenosis of the nasopharynx by obstructive scar tissue was confirmed within four weeks. A permanent tracheostomy provided long-term relief of the respiratory difficulty. This is the first report of choanal atresia or nasopharyngeal stenosis in a dog.

Partial colonic obstruction following ovariohysterectomy: a report of three cases.
Partial extramural obstruction of the descending colon was diagnosed in two dogs and a cat as a complication of elective ovariohysterectomy. In each case, the obstruction was caused by fibrous tissue that encircled or crossed the descending colon, severely restricting the organ's normal mobility and luminal diameter. Clinical signs secondary to obstipation were observed in two cases, five weeks and 27 months after elective ovariohysterectomy. In one dog without clinical signs, the adhesion was an incidental finding during a laparotomy performed nine years after the ovariohysterectomy. The fibrous adhesions were removed surgically in all three cases without additional complications.

Use of skin staples for rapid closure of gastrointestinal incisions in the treatment of canine linear foreign bodies.
A technique was developed for closure of gastrotomy and enterotomy incisions using disposable skin staples. The technique was used successfully in three dogs with gastrointestinal linear foreign bodies that required a gastrotomy and one or more enterotomies. The method allows for secure closure of gastrointestinal incisions and minimizes the surgical time in patients requiring multiple gastrointestinal incisions.

Pyometra and its complications.
The management of animals with cystic hyperplasia-pyometra complex can be a challenge. Careful interpretation of the history and physical examination, radiographic, and clinicopathologic findings will lead to an accurate diagnosis. Appropriate and rapid stabilization of the animal before surgical removal of the uterus will greatly decrease morbidity and mortality. Precise surgical technique when performing ovariohysterectomy will decrease postoperative complications.

Complications associated with the surgical treatment of prostatic abscessation.
Prostatic abscessation in the dog is a disease process in which diagnostic, therapeutic, and postoperative problems are frequently encountered. Several surgical techniques for the treatment of prostatic abscessation in the dog have been reported. However, few studies have described the indications for use of a particular technique or associated postoperative complications.

Problems associated with the surgical treatment of diseases involving the perineal region.
The problems associated with perineal surgery depend on the surgical procedure performed. Problems are encountered before, during, and after surgery. Appropriate preoperative assessment, proper surgical technique, and thorough postoperative management are required for successful results. Immediate recognition and treatment of problems is essential.
