Abstract
BACKGROUND: Sialoendoscopy is the standard treatment for sialolithiasis; however, some patients may be unlikely to benefit from an endoscopic approach. This study assesses predictors of failure in the endoscopic management of sialoliths. METHODS: Patients treated for sialolithiasis from 2012 to 2017 at two centers were stratified into 3 groups: successful interventional sialendoscopy, incisional sialolithotomy, and gland excision. Patient, disease, and surgical factors were compared. RESULTS: Interventional sialendoscopy was attempted in 156 of 206 cases and successful for 42 (27%). Endoscopically retrieved calculi were smaller (4.96 mm) compared to incisional sialolithotomy (7.90 mm). Nonendoscopic approaches were required more often in submandibular cases 87% (P ≤ .005). Palpable stones were present in 74% of incisional sialolithotomies (P < .001). Submandibular location (OR 3.50, 1.53-7.98), palpability (OR 2.74, 1.21-6.18), CT localization (OR 3.05, 1.32-7.10, P = .010), and increased diameter (OR 1.25, 1.09-1.44) were predictive of incisional management. CONCLUSION: Stone size/location, CT-localization, and palpability were predictive of calculi that require an incisional approach. If these factors are recognized, the surgeon can consider proceeding directly to incisional sialolithotomy. LEVEL OF EVIDENCE: III.
