Citation Atienza-Merino G.. La sialoendoscopia en el tratamiento de los procesos salivares obstructivos. [Sialendoscopy for the management of obstructive salivary gland disease] Santiago de Compostela: Galician Agency for Health Technology Assessment (AVALIA-T). CT2014/03. 2014 Authors' objectives To assess the effectiveness and safety of sialoendoscopy as a diagnostic/therapeutic technique in the management of obstructive salivary disorders.
Authors' conclusions Results and discussion: Forty-nine studies, all case series of a prospective and retrospective nature, were included in the review. Some had methodological limitations which could affect the results on effectiveness and safety. Joint analysis showed that in the 41 studies in which the sialoendoscopy technique was performed alone (2654 procedures) the effectiveness of resolution of the salivary obstruction was 76% and that in the 23 studies in which the multi-modal technique was performed, with close on 1500 sialoendoscopies, this was 91%. In the case of sialolithiasis, there are limitations on the size of the salivary calculi which can be extracted by means of graspers or baskets, i.e., up to 4 mm in the case of submandibular glands and 3 mm in that of parotid glands. In the case of larger sizes, alternative techniques may be necessary, such as intra- or extracorporeal lithotripsy, transoral surgery or endoscopy-assisted transoral surgery. Sialoendoscopy is
generally performed on an ambulatory basis, with local anaesthesia in the diagnosis and with sedation or general anaesthesia in the treatment. Like any intervention technique, sialoendoscopy has a learning curve which can range from 50 to 60 procedures.
Conclusions: The available scientific evidence on the effectiveness and safety of sialoendoscopy is based on observational studies, some of which have methodological limitations. Nevertheless, the results are consistent as to the technique's effectiveness when it comes to resolving the salivary obstruction, namely, 74% when used alone or 93% when used on a multimodal basis. Furthermore, sialoendoscopy substantially reduces the
number of sialoadenectomies performed, and its adverse effects are infrequent and mild. Its principal indications are chronic recurrent sialolithiasis, juvenile recurrent parotid sialoadenitis, radioactive iodine induced sialoadenitis and stenosis due to Sjögren's syndrome Indexing Status Subject indexing assigned by CRD MeSH Adult; Constriction, Pathologic; Diagnosis, Differential; Endoscopys; Salivary Ducts; Salivary Gland Diseases; Treatment Outcome Language Published Spanish Country of organisation Spain English summary An English language summary is available.
