A Case of Acute Cholecystitis Successfully Treated With Endoscopic Ultrasound-Guided Gallbladder Drainage in a Patient With Osteogenesis Imperfecta.

A 74-year-old man with severe osteogenesis imperfecta (OI) was admitted to our hospital because of repetitive cholecystitis due to a stone in the gallbladder neck. Because he had severe OI-related chest wall deformity and a high risk of complications from bronchial intubation, general anesthesia, and surgery, we performed endoscopic ultrasound-guided gallbladder drainage (EUS-GBD). The postprocedural clinical course was uneventful, and he was discharged in satisfactory condition. EUS-GBD is a treatment option for acute cholecystitis in surgically high-risk patients with OI. However, special attention should be paid to the influence of sedation on the respiratory and cardiovascular systems during the procedure.
