Pharyngeal lidocaine anesthesia is not necessary during EUS under sedation with analgesics.
Favorable tolerability rates were 85% for lidocaine group and 88% for saline group among endoscopists.
Patient satisfaction was significantly higher in the saline group, while the noninferiority margin was met.
Omitting lidocaine may lead to less discomfort and lower medical costs during EUS procedures.
