Conservative management of metallic sharp-pointed straight gastric and intestinal foreign bodies in dogs and cats: 17 cases (2003-2021).

Abstract

To describe the conservative management and outcome of gastrointestinal metallic sharp-pointed straight foreign bodies in dogs and cats. Clinical records of dogs and cats presented to a university teaching hospital between 2003 and 2021 with gastrointestinal metallic sharp-pointed straight foreign bodies (e.g. needles, pins, nails) were reviewed. Conservative management was defined as leaving the foreign body in situ. Cases were excluded if the foreign body was identified outside of the gastrointestinal tract (including oropharynx and oesophagus) or if it was removed by endoscopy or surgery as the first treatment choice. Patient signalment, presenting complaint, foreign body location, treatment, complications, gastrointestinal transit time, length of hospitalisation and outcome were recorded. A total of 17 cases (13 dogs and four cats) were included in the study, being treated with primary conservative therapeutic approach (11) or following failure of endoscopy (two), surgery (three) or both (one). Clinical signs associated with the foreign body were reported in three (17.6%) cases. Conservative management was successful in 15 (88.2%) cases, with no complications reported. Patients were clinically and radiographically monitored with variable supportive care. In two (11.8%) cases, surgery was subsequently performed as the foreign body failed to progress on repeated radiographs after 24 hours. Mean foreign body gastrointestinal transit time for patients treated conservatively was 59.2 (±31.4) hours. All patients survived to discharge. Conservative management is a treatment option for clinically stable cats and dogs with metallic sharp-pointed straight gastrointestinal foreign bodies in the absence of perforation.
