1341 Outcomes of Sialendoscopic Stone Retrieval Under Local Anaesthesia in The Outpatient Setting- A Single Surgeon’s Experience

Abstract

Abstract Aim The aim of this retrospective case series was to investigate the success rate of sialendoscopic stone retrieval under local anaesthetic. Method The records of 52 patients who underwent salivary endoscopy between September 2018 and February 2020 were reviewed. Included cases presented with at least one symptomatic major salivary gland, and sonographic or radiographic evidence of stone disease. Results A total of 25 patients (48%) and 27 stones were identified. Most cases (19/25) involved the submandibular gland, with a virtually even division between left and right sides. 19/25 patients underwent stone retrieval under local anaesthetic (LA) in the first instance (two of these patients had two stones). 6/25 patients underwent stone retrieval under general anaesthetic (GA) in the first instance, and this was successful in 5/6 cases. The overall success rate of LA sialendoscopic stone retrieval was 18/21 (86%), with 14/21 stones (66%) being successfully removed at the first treatment session and a further four at the subsequent treatment session. Under LA, 13/18 stones were removed intact, while the remaining 5 underwent fragmentation with an intraoral salivary pneumatic lithotripter (Cook Medical). Conclusions Sialendoscopic stone retrieval is a minimally invasive and effective treatment for both submandibular and parotid duct stones. It is possible to remove most stones under local anaesthetic at the first treatment session, using intraoral lithotripsy as an adjunct when indicated. This treatment modality provides therapeutic benefit with 86% success of stone retrieval under local anaesthetic with gland preservation in the vast majority of patients.
