RESUMO
OBJECTIVE: To report the outcomes of cats that underwent surgical correction for sialoceles. STUDY DESIGN: Multi-institutional retrospective cohort study. ANIMALS: Twenty-one client-owned cats. METHODS: Medical records were examined of cats diagnosed with sialocele, which underwent surgical intervention over an 11-year period at one of 10 referral hospitals. The data collected included signalment, clinical signs, diagnostic imaging, histopathology, surgical procedures performed, and postoperative complications. RESULTS: The most common presenting complaints for cats with sialocele included dysphagia and ptyalism. Only two cats had a recent history of trauma, and one was diagnosed with a concurrent sialolith. Most displayed visible tissue swelling, with ranulae being most common. Surgical treatment consisted of sialoadenectomy and/or marsupialization. Intraoperative complications occurred in three cats, and postoperative complications in five cats. No recurrence or development of contralateral sialoceles were reported during the follow-up period (30-968 days). CONCLUSION: The majority of cats did not have a clear underlying cause for developing a sialocele. The sublingual and mandibular salivary glands were presumed to be the most commonly affected. Mandibular and sublingual sialoadenectomy and/or marsupialization provided resolution of clinical signs to the 21 cats that underwent these procedures. CLINICAL SIGNIFICANCE: Sialocele, although rare, should remain a differential diagnosis when managing cats with relevant clinical signs. Surgical intervention appears to offer resolution of signs with apparently low overall risk of complication or short-term recurrence. In cats it is necessary to evaluate whether sialoadenectomy is necessary, or whether marsupialization alone should be attempted as a less invasive first-line surgical intervention.
RESUMO
OBJECTIVE: To describe the use of a novel wound dressing that delivers nitric oxide (NO) to naturally occurring traumatic wounds in dogs. ANIMALS: 24 client-owned dogs with 30 wounds. METHODS: Dogs were presented with acute traumatic wounds requiring open wound management. Wounds were bandaged with a novel NO wound dressing and reassessed as needed for continued open wound management until wounds healed by second intention or wound closure was recommended. Dogs could be removed from the study at any point at the clinician's discretion. RESULTS: All wounds had the novel NO wound dressing used during open wound management until wound closure was recommended. Median time to wound closure was 6 days (range, 2 to 42). There were no complications directly attributed to the use of the novel wound dressing that clinically affected the dogs. Three wounds dehisced following wound closure. Wound healing was confirmed in 19 dogs with 25 wounds, with 3 dogs lost to follow-up prior to suture removal. Only 7.1% of wounds had clinical signs consistent with wound infection following wound closure. CLINICAL RELEVANCE: The novel NO wound dressing was easy to use and well tolerated in dogs with naturally occurring traumatic wounds. It can be used throughout all phases of wound healing, simplifying open wound management.
RESUMO
Laryngeal diseases are manifested by obstructive breathing patterns reflecting functional or mechanical upper airway obstruction. Laryngeal paralysis is the most common disease of the larynx. Diagnosis requires close attention to anesthetic plane and coordination of respiratory effort with laryngeal motion. Surgical arytenoid lateralization improves clinical signs and quality of life in dogs; however, aspiration pneumonia is a recognized complication, and generalized neuropathy can progress. Laryngeal collapse can result from any cause of chronic upper airway obstruction but is most often associated with brachycephalic obstructive airway syndrome. Although uncommon, laryngeal neoplasia has a guarded to grave prognosis regardless of treatment.

Postoperative seizures occur in 5-12% of dogs following surgical attenuation of congenital extrahepatic portosystemic shunts (CEPSS) and are often refractory to treatment. Because pugs are predisposed to necrotizing meningoencephalitis, they may be at higher risk of developing neurologic complications after CEPSS attenuation. We hypothesized that pugs have a higher prevalence of postoperative neurologic complications and that pugs who died due to neurologic complications would have evidence of encephalitis at necropsy. Records were searched for pugs that had undergone surgical correction of a single extrahepatic CEPSS. Fourteen pugs met the inclusion criteria and were compared with a control group of 30 dogs of varying breeds who also underwent surgical attenuation for a single CEPSS. Four of 14 pugs (28.6%) died or were euthanized within 1 mo after surgery for neurologic complications, compared with only 1 of 30 dogs in the control group (P < .029). No evidence of necrotizing meningoencephalitis was seen on necropsy. Pugs may be at an increased risk of developing fatal neurologic complications following surgical attenuation for CEPSS. Further studies are indicated to investigate reasons for this increased risk, as well as to determine any factors that may indicate which pugs are at higher risk.

Ear disease, such as otitis externa, resulting in aggressive head shaking or ear scratching, is the most common cause of the development of aural hematomas in dogs and cats. An underlying immunologic cause has also been proposed to explain cartilage and blood vessel fragility. Numerous options exist for management of aural hematomas, from medical management alone with corticosteroids, to simple hematoma centesis, to surgical intervention. Because this condition is usually secondary to another disease process, regardless of mode of treatment, likelihood of recurrence is low if the underlying condition is managed properly.

This study reports the survival to discharge, postdischarge survival, and long-term outcome of dogs following surgical correction of a persistent right aortic arch (PRAA). Information for 52 dogs, 28 dogs, and 23 dogs was available for analysis of survival to discharge, postdischarge survival, and long-term outcome, respectively. Ninety-two percent of dogs survived to the time of discharge and 18% of dogs surviving to discharge were euthanized within 2 mo of surgery. Breed, age at the time of presentation, and gender were not correlated with increased odds of death prior to discharge from the hospital. Long-term outcome for dogs was excellent in 30%, good in 57%, and poor in 13% of dogs. Although this study shows a relatively high mortality rate prior to discharge from the hospital and within 2 mo of surgical treatment, the long-term outcome is good or excellent in 87% of survivors. Dogs frequently display either residual clinical signs or require dietary modification long-term, but owner satisfaction is high.

The most common disease process involving the larynx is laryngeal paralysis, which occurs much more frequently in dogs than in cats. Diagnosis of laryngeal paralysis requires close attention to anesthetic plane and coordination of respiratory effort with laryngeal motion. Surgical arytenoid lateralization improves respiration and quality of life in dogs with laryngeal paralysis; however, aspiration pneumonia is a recognized complication, and generalized neuropathy can progress. Laryngeal collapse can result from any cause of chronic upper airway obstruction, but is most often associated with unaddressed brachycephalic airway syndrome. Laryngeal neoplasia, while generally uncommon, occurs more frequently in cats than in dogs.

Retroperitoneal abscesses, although uncommon, are clinically important. Medical records of seven dogs with naturally occurring retroperitoneal infections from 1999 to 2011 were reviewed to document historical, examination, clinicopathologic, imaging, and surgical findings; etiologic agents; and outcome. Middle-aged sporting dogs were most commonly affected. Dogs were febrile with evidence of either abdominal or lumbar pain. Although traditional radiography can aid in diagnosis, ultrasound appeared to be a more sensitive indicator of disease within the retroperitoneal space. Numerous bacteria were isolated from the abscesses, with anaerobic and facultative anaerobic bacteria being the most commonly isolated. Etiology was largely unknown, but migrating plant material was often suspected. Resolution of the infection required surgical intervention as well as prolonged antibiotic therapy. Although recurrence is possible, outcome can be favorable with no long-term sequela.

Intermuscular lipomas (IML) in dogs can be associated with ominous clinical signs, especially in the thoracic limb. However, the prognosis is excellent following surgical excision. There is a paucity of information in the veterinary literature regarding IML. Our objective was to describe the anatomical location, imaging techniques, and clinical findings in a series of dogs that were diagnosed and treated for IML. The prevalence of thoracic versus pelvic limb IML was not different. Most IML of the thoracic limb were located in the axilla. Operative time for IML of the thoracic and pelvic limb averaged 60 minutes. Complications were rare after marginal surgical excision and recurrence was not seen in any of the cases in this report. Intermuscular lipomas of the axilla are as common as IML of the caudal thigh. Surgical treatment of both axillary and caudal-thigh IML is associated with an excellent prognosis in dogs.

Paired serum bile acid (SBA) samples from 30 dogs with presumptive hepatobiliary disease and 30 apparently healthy dogs were submitted to three diagnostic laboratories to validate agreement between these facilities. Sensitivities and specificities ranged from 50% to 70% and from 74% to 85%, respectively, for all laboratories. The κ index confirmed almost perfect agreement between laboratories. Variation in sample handling and processing by different laboratories should not be considered a primary factor when aberrant SBA values are encountered. Documenting agreement between laboratories is essential as inconsistencies could direct unnecessary medical or surgical intervention when patients are evaluated at different hospitals during the course of their disease.

CASE DESCRIPTION: A 12-year-old castrated male Labrador Retriever was evaluated for clinical signs associated with colorectal obstruction. CLINICAL FINDINGS: The dog had a 2-week history of tenesmus and hematochezia. On rectal examination, an annular colorectal mass was palpable extending orad into the pelvic canal. The original diagnosis of the colorectal mass was a mucosal adenoma. The dog was maintained on a low-residue diet and fecal softeners for a period of 13 months after initial diagnosis. At that time, medical management was no longer effective. TREATMENT AND OUTCOME: Placement of a colonic stent was chosen to palliate the clinical signs associated with colorectal obstruction. By use of fluoroscopic and colonoscopic guidance, a nitinol stent was placed intraluminally to open the obstructed region. Placement of the stent resulted in improvement of clinical signs, although tenesmus and obstipation occurred periodically after stent placement. At 212 days after stent placement, the patient had extensive improvement in clinical signs with minimal complications; however, clinical signs became severe at 238 days after stent placement, and the dog was euthanized. Histologic evaluation of the rectal tumor from samples obtained during necropsy revealed that the tumor had undergone malignant transformation to a carcinoma in situ. CLINICAL RELEVANCE: A stent was successfully placed in the colon and rectum to relieve obstruction associated with a tumor originally diagnosed as a benign neoplasm. Placement of colorectal stents may be an option for the palliation of colorectal obstruction secondary to neoplastic disease; however, clinical signs may persist, and continuation of medical management may be necessary.

OBJECTIVE: To evaluate the long-term prognosis of cats with a congenital extrahepatic portosystemic shunt (CEPSS) attenuated through gradual occlusion with cellophane banding (CB). DESIGN: Retrospective case series. ANIMALS: 9 cats with a CEPSS that was attenuated with CB. PROCEDURES: Medical records of cats surgically treated for CEPSS by means of CB from January 2000 through March 2007 were reviewed. Extracted data included preoperative clinical signs, medications, diagnostic results including serum bile acids concentrations, surgical technique, intraoperative and postoperative complications, and long-term follow-up information. RESULTS: 2 cats that developed refractory seizures were euthanized within 3 days after the CB procedure. Seven of the 9 cats survived to 15 days after surgery. Four cats did not have any clinical signs of CEPSS at long-term follow up. At that time, 5 cats had a postprandial SBA concentration within reference limits and 1 cat had persistent ptyalism. One cat had biurate ammonium stones removed > 2 years after surgery. One cat was euthanized 105 days after surgery because of uncontrolled seizures. The 3-year survival rate was 66%. CONCLUSIONS AND CLINICAL RELEVANCE: Uncontrolled seizure activity was the most common cause of death after CB. Long-term outcome for cats with CEPSS was fair to good after the procedure. Cats with a CEPSS surviving the immediate postoperative period had a fair to good long-term outcome. Cellophane banding without intraoperative attenuation appears to be an acceptable technique for gradual occlusion of a CEPSS in cats. Cats should be monitored closely for development of neurologic disorders in the postoperative period.

Benign, inflammatory polyps may affect the nasopharynx and auditory canal of cats. It has been proposed that inflammation induced by infectious disease agents could trigger polyp formation. The objective of this pilot study was to determine the prevalence of feline herpesvirus-1 (FHV-1), feline calicivirus (FCV), Mycoplasma species, Bartonella species and Chlamydophila felis nucleic acids in polyp tissues collected from 30 clinically affected cats. Samples collected from the tympanic bulla from 12 clinically normal cats were also assayed. DNA or RNA of some of the target agents were amplified from samples from 25% of normal cats and 33% of affected cats; however, statistical associations were not detected for individual agent results or grouped results. The study documents that common oropharyngeal or blood borne agents can be detected in the tympanic bullae of normal cats. Failure to consistently amplify RNA or DNA of the select agents from polyp tissues suggests the agents studied were not directly associated with the pathogenesis of this syndrome in the cats tested. Alternately, the inflammatory response may have cleared microbial nucleic acids to undetectable levels by the time of sample collection.

Retention of tablets or capsules in the feline esophagus can be associated with esophagitis and esophageal stricture formation. The objective of this study was to evaluate the esophageal passage of tablets and capsules when administered with either a one-step pill gun with flavored liquid (FlavoRx pill glide) or a pill delivery treat (Pill Pockets). Four different medication administrations were evaluated on different days in eight normal cats: tablets with FlavoRx pill glide (T-FG), tablets with pill delivery treats (T-PP), capsules with FlavoRx pill glide (C-FG) and capsules with pill delivery treats (C-PP). The estimated average transit time was 36s for T-FG, 60s for T-PP, 16s for C-FG, and 24s for C-PP. The results of this study suggest that either pill delivery method is acceptable for successful passage of tablets or capsules into the stomach of cats using a single replicate.

In this report, we describe a simple, safe, and efficacious technique for orchiectomy and scrotal ablation with the use of a carbon dioxide light amplification by stimulated emission of radiation (laser) in sugar gliders (Petaurus breviceps). The study population included nine sugar gliders, ages 2-24 mo, presented for orchiectomy. After induction of general anesthesia, orchiectomy and scrotal ablation were performed by severing the scrotal stalk with the laser. All sugar gliders were discharged the same day. Mean anesthesia time was 6.09 +/- 0.94 min. Mean surgery time was 15.11 +/- 8.39 sec, and mean recovery time was 4.11 +/- 3.60 min. With an outlier removed, mean recovery time was 2.95 +/- 1.03 min. No serious postoperative surgical complications were observed. The technique described is a simple procedure with rapid surgical and recovery times that has the potential to become the standard procedure for orchiectomy and scrotal ablation in sugar gliders.

Removal of the anal sacs is a frequently performed surgery in dogs. It is most often indicated for definitive treatment of chronic anal sacculitis. The anal sacs are intimately associated with the external anal sphincter; therefore, fecal incontinence resulting from damage to this muscle or its innervation is a potential complication of anal sacculectomy. Fistula formation and incisional infection are other possible complications. In general, the overall incidence of complications after anal sacculectomy is low.

OBJECTIVE: To determine the long-term survival rate and factors that affect survival time of domestic ferrets treated surgically for hyperadrenocorticism. STUDY DESIGN: Retrospective case series. ANIMALS: 130 ferrets with hyperadrenocorticism that were treated surgically. PROCEDURES: Medical records of ferrets surgically treated for hyperadrenocorticism were reviewed. Data recorded included signalment, duration of clinical signs prior to hospital admission, CBC values, serum biochemical analysis results, anesthetic time, surgical time, concurrent diseases, adrenal gland affected (right, left, or both [bilateral]), histopathologic diagnosis, surgical procedure, caudal vena caval involvement (yes or no), postoperative melena (yes or no), days in hospital after surgery, and whether clinical signs of hyperadrenocorticism developed after surgery. RESULTS: 130 ferrets were entered in the study (11 of 130 ferrets were admitted and underwent surgery twice). The 1- and 2-year survival rates were 98% and 88%, respectively. A 50% survival rate was never reached. Combined partial adrenal gland resection with cryosurgery had a significantly negative effect on survival time. No other risk factors were identified. Survival time was not significantly affected by either histopathologic diagnosis or specific affected adrenal gland (right, left, or bilateral). CONCLUSIONS AND CLINICAL RELEVANCE: Ferrets with adrenal gland masses that were treated surgically had a good prognosis. Survival time of ferrets with hyperadrenocorticism undergoing surgery was not affected by the histologic characteristic of the tumor, the adrenal glands affected (right, left, or bilateral), or complete versus partial adrenal gland resection. Debulking was a sufficient surgical technique to allow a favorable long-term outcome when complete excision was not possible.

It is estimated that there are over 5 million homeless animals in the United States. While the veterinary profession continues to evolve in advanced specialty disciplines, animal shelters in every community lack resources for basic care. Concurrently, veterinary students, interns, and residents have less opportunity for practical primary and secondary veterinary care experiences in tertiary-care institutions that focus on specialty training. The two main goals of this project were (1) to provide practical medical and animal-welfare experiences to veterinary students, interns, and residents, under faculty supervision, and (2) to care for animals with medical problems beyond a typical shelter's technical capabilities and budget. Over a two-year period, 22 animals from one humane society were treated at Colorado State University Veterinary Medical Center. Initial funding for medical expenses was provided by PetSmart Charities. All 22 animals were successfully treated and subsequently adopted. The results suggest that collaboration between a tertiary-care facility and a humane shelter can be used successfully to teach advanced procedures and to save homeless animals. The project demonstrated that linking a veterinary teaching hospital's resources to a humane shelter's needs did not financially affect either institution. It is hoped that such a program might be used as a model and be perpetuated in other communities.

Pyothorax is the accumulation of septic suppurative inflammation within the pleural cavity. The cause and source of infection in dogs and cats often are unknown. Management of these cases can be challenging, because controversy exists over the best method for treatment. Reported outcomes and recurrence rates vary widely.
