Extended palatoplasty as surgical treatment for nasopharyngeal stenosis in six cats.

OBJECTIVE: To describe the use of extended palatoplasty as treatment of caudal nasopharyngeal stenosis in cats. MATERIALS AND METHODS: CT was used to confirm the diagnosis in cats with clinical signs consistent with nasopharyngeal stenosis. Extended palatoplasty rostral to the tonsils using monopolar electrocautery allowed simultaneous removal of the caudal soft palate together with the stenotic area. Cats were re-evaluated 2 weeks postoperatively. Telephone interview was used to obtain long-term follow-up. RESULTS: Six domestic shorthair cats were diagnosed with nasopharyngeal stenosis, with clinical signs of snoring (n=4), stertor (n=4), nasal discharge (n=3) and sneezing (n=1). CT scan identified a soft-tissue stricture at the level of the caudal nasopharynx in all cats. Other abnormalities included bilateral rhinitis (n=3), retropharyngeal adenomegaly (n=2), unilateral sinusitis (n=1) and bilateral otitis externa with unilateral otitis media (n=1). Excision of the caudal soft palate and the entire stenotic soft-tissue membrane was successful in all six cats. No pre-, intra- or postoperative complications were observed. Short-term outcome revealed clinical improvement in all cases. Long-term outcome revealed no recurrence of clinical signs in four cats. In one cat, occasional sneezing was reported. One cat died 1 month postoperatively for reasons unrelated to the respiratory condition. CLINICAL SIGNIFICANCE: Extended palatoplasty was an effective technique to treat caudal nasopharyngeal stenosis and provide improvement of clinical signs without postoperative complications in all cases.

Endoscopic and surgical removal of oesophageal and gastric fishhook foreign bodies in 33 animals.

OBJECTIVES: To describe the location, retrieval, frequency of surgery and complications associated with fishhook foreign bodies. MATERIALS AND METHODS: Retrospective evaluation of the medical records of cats and dogs admitted between 2010 and 2016 after fishhook ingestion. RESULTS: A total of 33 cases (2 cats and 31 dogs) were included. The most common locations were the proximal oesophagus [12/33 (36%)] and stomach [11/33 (33%)]. Endoscopic retrieval was successful in 27 of 33 cases (82%); oesophageal perforation was the only recorded complication, occurring in six of 33 (18%) cases. Surgery was performed in six cases (18%), and no early complications were recorded. The survival rate was 100%. CLINICAL SIGNIFICANCE: The endoscopic removal of ingested fishhooks is highly successful. In the present study, survival to discharge was 100%, even in cases of oesophageal perforation or in cases requiring surgery.

Comparative use of CO2 laser, diode laser and monopolar electrocautery for resection of the soft palate in dogs with brachycephalic airway obstructive syndrome.

Clinical results, complications and the outcome of using either a carbon dioxide (CO2) laser, diode laser or electrocautery (ELEC) for resection of the soft palate with an extended palatoplasty technique in brachycephalic dogs with upper airway obstructive syndrome were compared. Dogs were randomly allocated into three groups (n=20 in each group): ELEC, diode and CO2 groups. The palatoplasty was made at the rostral aspect of the tonsils. A respiratory clinical score, ranging from 0 (normal) to 4 (cyanosis), was attributed to each dog before surgery and at 0 hours, 24 hours, two weeks and six months after surgery. A favourable outcome was defined as a one point or greater decrease in score 24 hours after surgery. The proportion of dogs with a favourable outcome was significantly higher in the CO2 (n=15) and ELEC groups (n=15) in comparison with the diode group (n=7) (OR=5.6, 95 per cent confidence interval 1.4 to 21.9). Surgical time was significantly shorter (P<0.001; mean [sd] 510 [178] seconds), and bleeding was less common (P<0.001; 30 per cent of cases) in the CO2 group. Complications were most frequent with the diode group (two cases of death and two cases of tracheostomy). The final outcome for all groups (n=57) was considered excellent in 79 per cent of cases and was considered good in 21 per cent.
