Finney and Jaboulay pyloroplasties for the treatment of benign gastric outlet lesions in dogs and cats: technique and outcome in 13 cases (2015-2024).

OBJECTIVES: To describe the use, complications and outcome of Finney or Jaboulay pyloroplasties for the treatment of benign gastric outlet lesions in dogs and cats. MATERIALS AND METHODS: The medical records of dogs and cats surgically treated with Finney or Jaboulay pyloroplasty for benign gastric outflow tract disease in three institutions between January 1, 2015 and August 31, 2023 were retrospectively reviewed. RESULTS: Eight dogs and five cats were diagnosed with benign obstructive or perforating gastric outlet lesions, including chronic hypertrophic pyloric gastropathy (n = 4), perforating pyloro-duodenal peptic ulcer (4), sub-obstructive pyloro-duodenal eosinophilic sclerosing fibroplasia (2) and antral or proximal duodenal obstructive mass (3). Nine cases were treated using hand-sewn Finney pyloroplasty and four cases were treated using stapled Jaboulay pyloroplasty. No major complications were recorded. Cases were followed for a median of 16.1 [11 to 29.6] months. At the last follow-up, the outcome was excellent in all cases, with no clinical signs recorded and no medical treatment required. CLINICAL SIGNIFICANCE: This case series suggests that Finney and Jaboulay pyloroplasties were safe and effective procedures for the surgical treatment of benign obstructive or perforating gastric outlet lesions in dogs and cats.

Outcome of dogs and cats with benign oesophageal strictures after balloon dilatation or stenting: 27 cases (2002-2019).

OBJECTIVES: Acquired oesophageal strictures remain challenging to manage in canine and feline patients. The aims of this study were to describe the treatment, complications, short-term outcome and long-term follow-up of benign oesophageal strictures treated by balloon dilatation or stenting in dogs and cats and to describe adjunctive techniques to minimise the complication rate of stent placement. MATERIALS AND METHODS: Retrospective analysis of medical records of dogs and cats with benign oesophageal stricture diagnosed under endoscopy between 2002 and 2019. RESULTS: Eighteen dogs and nine cats were included, representing 39 strictures. Balloon dilatation was used as first-line therapy, with a good outcome in 59% of cases. Stents were placed in eight cases due to stricture recurrence; 88% had a long-term satisfactory outcome. Short-term complications occurred in six of eight cases; migration and aberrant mucosal reaction were uncommon. In three cases, progressive mesh cutting during follow-up reduced discomfort and trichobezoars formation and improved long-term stent tolerance. Overall median survival time was 730 days. CLINICAL SIGNIFICANCE: Long-term prognosis of balloon dilatation as a first-line therapy for esophageal strictures and of stenting as a rescue therapy was considered satisfactory. Although discomfort associated with stenting was frequent, tolerability might be improved by per-endoscopic adjunctive techniques.

Treatment of inflammatory rectal strictures by digital bougienage: a retrospective study of nine cases.

OBJECTIVES: Inflammatory rectal strictures in dogs and cats have been rarely reported. The aim of this study was to describe nine cases and their treatment by digital bougienage. METHODS: Medical records of dogs and cats referred for constipation, dyschezia or tenesmus and diagnosed with an inflammatory rectal stricture were obtained from the database of two referral centres between 2007 and 2014 and reviewed. RESULTS: Four dogs and five cats met the inclusion criteria. Four of the five cats were purebred kittens. Three cats and two dogs had a history of diarrhoea and two dogs had a history of bone ingestion. Digital rectal examination revealed rectal strictures in all cases. Histopathology revealed a lymphoplasmacytic infiltration in all four dogs and in two cats. All cases were treated by digital bougienage. A psyllium-enriched diet was prescribed in all cats and in two dogs. A complete resolution of clinical signs was reported in all eight cases for which follow-up information was available. CLINICAL SIGNIFICANCE: Benign rectal strictures associated with gastrointestinal inflammation should be routinely included in the differential diagnosis of constipation, tenesmus and dyschezia, especially after an episode of acute or chronic diarrhoea. The treatment described here is simple, minimally invasive and effective in the long term.

Comparison of 3 Handling Techniques for Endoscopically Obtained Gastric and Duodenal Biopsy Specimens: A Prospective Study in Dogs and Cats.

BACKGROUND: Limited evidence exists in the literature regarding whether a specific mount is preferable to use for processing endoscopically obtained gastrointestinal biopsy specimens. HYPOTHESIS/OBJECTIVES: To compare 3 methods of handling endoscopically obtained gastrointestinal biopsy specimens from collection to laboratory processing and to determine if any technique produced superior results. ANIMALS: Twenty-three dogs and cats presented for gastrointestinal signs. METHODS: Prospective study of dogs and cats presented with gastrointestinal signs to a veterinary teaching referral hospital which underwent upper gastrointestinal endoscopy. Biopsy specimens were taken from the stomach and duodenum and submitted to the laboratory using 3 techniques: mounted on a cucumber slice, mounted on a moisturized synthetic foam sponge, and floating free in formalin. The techniques were compared with regard to the specimens' width, orientation, presence of artifacts, and pathologist's confidence in diagnosis. RESULTS: Twenty-three patients were included, with a total of 528 biopsies collected. Specimens on cucumber slice and on sponge were significantly wider (P < .001 and P = .001, respectively) compared to those floating free in formalin (mean width of 3.81 versus 3.31 and 2.52 mm, respectively). However, specimens on synthetic sponge had significantly fewer artifacts compared to those on cucumber slice (P = .05) and those floating free in formalin (P = .02). Confidence in the diagnosis also was superior with the sponge technique over floating free specimens (P = .002). CONCLUSIONS AND CLINICAL IMPORTANCE: The use of mounted gastrointestinal biopsy specimens was superior over the use of specimens floating free in formalin. This technique improved the quality of the specimens and the pathologist's confidence in their histopathologic interpretation.

Emesis in dogs: a review.

Emesis is a common presenting sign in small animal practice. It requires a rational approach to management that is based upon a sound understanding of pathophysiology combined with logical decision making. This review, which assesses the weight of available evidence, outlines the physiology of the vomiting reflex, causes of emesis, the consequences of emesis and the approach to clinical management of the vomiting dog. The applicability of diagnostic testing modalities and the merit of traditional approaches to management, such as dietary changes, are discussed. The role and usefulness of both traditional and novel anti-emetic drugs is examined, including in specific circumstances such as following cytotoxic drug treatment. The review also examines areas in which common clinical practice is not necessarily supported by objective evidence and, as such, highlights questions worthy of further clinical research.

Long-term results of upper respiratory syndrome surgery and gastrointestinal tract medical treatment in 51 brachycephalic dogs.

OBJECTIVES: After a first clinical study showing a high prevalence of gastrointestinal tract diseases in brachycephalic dogs presented for upper respiratory syndrome, a prospective study was performed to determine the influence of medical treatment for gastrointestinal tract disorders associated with upper respiratory syndrome surgery. METHODS: The gastrointestinal tract and respiratory disorders of 61 brachycephalic dogs presented for upper respiratory syndrome were evaluated. Together with surgery of the upper respiratory tract, a specific gastrointestinal medical treatment was administered. A minimal follow-up of six months was required for inclusion. RESULTS: Palatoplasty with rhinoplasty was the most common surgical correction (88.5 per cent). The mortality rate in the perioperative period was 3.3 per cent. Minor complications accounted for 26.2 per cent of cases. No aspiration pneumonia was encountered. A sufficient follow-up was obtained in 51 dogs. The improvement was judged by the owners as excellent or good in 88.3 per cent of the respiratory disorders and in 91.4 per cent of the gastrointestinal disorders. Clinically, a statistically significant improvement was obtained for both respiratory and gastrointestinal disorders. CLINICAL SIGNIFICANCE: In comparison with other studies, digestive tract medical treatment combined with upper respiratory surgery seems to decrease the complication rate and improve the prognosis of dogs presented for upper respiratory syndrome.

Prevalence of gastrointestinal tract lesions in 73 brachycephalic dogs with upper respiratory syndrome.

OBJECTIVES: To determine the prevalence of gastrointestinal tract lesions in brachycephalic dogs with upper respiratory tract disease. METHODS: The gastrointestinal tract and respiratory disorders of 73 brachycephalic dogs presented with upper respiratory signs were evaluated. Clinical signs and endoscopic and histological anomalies of the upper digestive tract were analysed. RESULTS: A very high prevalence of gastrointestinal tract problems in brachycephalic dogs presented with upper respiratory problems was observed clinically, endoscopically and histologically. Endoscopic anomalies of the upper digestive tract were present even in dogs without digestive clinical signs. Furthermore, histological evaluation of the digestive tract sometimes showed inflammatory lesions not macroscopically visible at endoscopy. Statistical analysis showed a relationship between the severity of the respiratory and digestive signs. This was significant in French bulldogs, males and heavy brachycephalic dogs. CLINICAL SIGNIFICANCE: These observations show a correlation between upper respiratory and gastrointestinal tract problems in brachycephalic breeds with upper respiratory disease. Surgical treatment of respiratory disease could improve the digestive clinical signs, and/or gastro-oesophageal medical treatment could improve the outcome for surgically treated brachycephalic dogs.
