Abstract

The endoscopically controlled electrohydraulic shock wave lithotripsy (EISL) of salivary stones was performed on 29 patients with submandibular duct stones as a new non-surgical treatment of sialolithiasis. Under local anesthesia, a flexible fiberscope with an additional probe to generate shock waves is placed into the submandibular duct. Under endoscopic monitoring the fiberscope is advanced until the stone is identified. For stone disintegration, the probe must be situated 1 mm in front of the concrement. The fragmentation itself is performed by pressure waves generated by a sparkover at the tip of the probe. By means of the endoscopically controlled shock wave lithotripsy (EISL), it was possible to achieve complete stone fragmentation in 20 of 29 patients without serious side effects. In 3 patients only partial stone fragmentation could be achieved due to the stone quality. The endoscopically controlled electrohydraulic intracorporal shock wave lithotripsy (EISL) represents a novel non-invasive therapy for endoscopically accessible salivary gland stones. This therapy is performed on an outpatient basis with little inconvenience to the patient. The advantage in comparison to the endoscopically controlled laser lithotripsy will be discussed.
