OBJECTIVE To evaluate perioperative morbidity and outcome in dogs and cats undergoing esophageal surgery. DESIGN Retrospective case series. ANIMALS 63 client-owned dogs and 9 client-owned cats. PROCEDURES Medical records of dogs and cats that underwent esophageal surgery were reviewed for information on signalment, history, results of preoperative diagnostic testing, condition treated, details of surgery, intraoperative complications, and postoperative complications. Long-term follow-up data were obtained via veterinarian and client telephone conversations. The relationship between complications and survival to hospital discharge was evaluated by means of regression analysis. RESULTS The most common indication for surgical intervention was an esophageal foreign body in dogs (50/63 [79%]) and esophageal stricture in cats (3/9). Complications were documented in 54% (34/63) of dogs and 3 of 9 cats. The most common immediate postoperative complications were respiratory in nature (9 dogs, 1 cat). Partial esophagectomy and resection with anastomosis were significantly associated with the development of immediate postoperative complications in dogs. The most common delayed postoperative complications were persistent regurgitation (7 dogs) and esophageal stricture formation (3 dogs, 1 cat). For dogs, a mass lesion and increasing lesion size were significantly associated with the development of delayed postoperative complications. Six dogs (10%) and 1 cat died or were euthanized prior to discharge, and pneumomediastinum and leukopenia were negative prognostic factors for dogs being discharged from the hospital. CONCLUSIONS AND CLINICAL RELEVANCE Results of this study suggested that the short-term prognosis for dogs and cats that survive surgery for treatment of esophageal lesions is favorable, with 90% of patients discharged from the hospital (57/63 dogs; 8/9 cats). However, dogs treated for more extensive esophageal lesions as well as those undergoing esophagectomy or resection and anastomosis were more likely to develop postoperative complications.
Objective: To identify physical exam findings, clinicopathological parameters, time to surgery, empirical antimicrobial use, and culture results that could be associated with outcome in cats with septic peritonitis (SP). Design:Retrospective cohort study of cats from 2002 to 2015.Setting: Four university teaching hospitals.Animals: Eighty-three cats diagnosed with SP by cytology or culture. Interventions: NoneMeasurements and Main Results: Fifty-eight cats survived to discharge (69.9%); 1 cat was euthanized in surgery; 20 were euthanized postoperatively; 4 cats suffered cardiac arrest after surgery.The most common etiology of SP was secondary SP due to gastrointestinal perforation (49.4%), followed by primary SP (22.3%). Mean blood glucose concentration was significantly different between survivors and nonsurvivors (P = 0.006). Cats that received appropriate empirical antibiotic therapy were 4.4 times more likely to survive than cats that did not receive appropriate antibiotics (P = 0.018). Conclusions:As previously documented, SP secondary to gastrointestinal leakage was the most common etiology. In this population, cats with a higher blood glucose concentration on presentation had a worse prognosis. Cats that received appropriate empirical antimicrobial therapy were more likely to survive.

Objective To evaluate the frequency of clinical signs, dose ingested, and outcome in a large group of dogs with bromethalin ingestion. Design Retrospective cohort study of dogs from 2010 to 2016. Setting Three university teaching hospitals and 1 private practice. Animals A total of 192 dogs with bromethalin ingestion. Measurements and Main Results Total 192 cases were identified, of which 25 dogs developed clinical signs. Five cases initially had severe neurological signs and were euthanized. A sum of 187 dogs survived to discharge. The total ingested dose was recorded in 59 dogs with a median (interquartile range) 0.2 mg/kg (0.28 mg/kg). The remaining 133 dogs had confirmed ingestion reported by owners (witnessed ingestion or colored feces) but the total dose could not be calculated. The median (interquartile range) time to presentation for all dogs was 2 hours (4.8 h). A majority of patients were treated on an outpatient basis (121/192) and 71 of 192 were treated as inpatients with 58 of 71 receiving fluid diuresis. Decontamination was performed in 179 dogs including emesis induction (14), activated charcoal administration (42), and both (123). Emesis was successful in 128 dogs and apomorphine was the most common emetic agent (121). Mild to severe clinical signs at admission were reported in 19 cases including vomiting (6), tremors (5), lethargy (4), ataxia (3), weakness (2), diarrhea (2), collapse (2), and and anorexia (2). One case developed ataxia and tremors within 72 hours of admission. Conclusions and Clinical Relevance Symptoms of bromethalin toxicosis are uncommon, and most ingested doses are well below the reported dose expected to cause clinical signs. In this patient population, prognosis was excellent unless severe clinical signs were noted, which carried a high euthanasia rate. Effects of treatment on outcome could not be evaluated due to the low number of patients that developed clinical signs.
