Aims: Sialendoscopy is a minimally invasive endoscopic diagnostic and therapeutic intervention, used as a gland-sparing option to avoid upfront open salivary gland surgery. Indications include recurrent sialadenitis, and salivary duct strictures. Currently, St Vincent’s Hospital is the only public hospital in Victoria offering sialendoscopy. This paper outlines the surgical technique for endoscopic evaluation and treatment of recurrent sialadenitis, and reviews the predictors of successful sialendoscopy. Methods: Retrospective cohort study of seven years (2015 to 2022) for all adult patients (>18 years old) undergoing sialendoscopy as St Vincent’s Hospital Melbourne. Results: Eighty sialendoscopic procedures on seventy-five patients were included into the study. Parotid gland sialendoscopy (68.8%, n=55/80) was more common than submandibular duct (28.1%, n=25/80). The most common indication was sialolithiasis (67.5%, n=54/80), stricture (37.5%, n=30/80), and other anatomical abnormalities (17.5%, n=14/80). Minor complications rate was 16.3% (n=13/80), most commonly creation of a false passage (11.3%, n=9/80) with spontaneous resolution. There were no major or long-term complications. Mean operative time was 49 minutes. In patients with radiological evidence of sialolithiasis, 60.4% were located intraoperatively, and of these 63.2% had stones successfully retrieved. Mean follow up was 17.2 months and at conclusion of follow up 42% of patients had complete resolution of symptoms. Stones being distally located in the duct was found to be more strongly associated with successful retrieval than size. Conclusions: Sialendoscopy is a safe and efficacious procedure in the first instance for stone, strictures and recurrent sialadenitis on patients who would otherwise have had ablative surgery. It does not make open surgery obsolete but provides a safe, minimally invasive, gland-preserving alternative for many patients
