Background and Study Aim: Advance biliopancreatic endoscopies are nowadays performed in non-operating room anesthesia (NORA) under general anesthesia (GA). We evaluate the outcomes of non-intubated patients in prone position who received GA for endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) in a tertiary referral center for digestive endoscopy. Patients and Methods: Anesthesiological records, anamnestic, and intraoperative data of patients who underwent advanced therapeutic biliopancreatic endoscopies at our tertiary referral center from January 2019 until January 2020 were collected in the present observational study. Results: One hundred fifty-three patients (93 M; median age: 68-year-old; mean ASA status: 2) were considered eligible for a procedure in the prone position with GA in spontaneous breathing. Prone position was always the initial setting. Propofol administration through a target-controlled infusion (TCI) pump was the choice to achieve GA. In our experience, desaturation appears to be the most frequent adverse event, accounting for 35% of cases (55/153). Treatment foresaw additional oxygen through a nasopharyngeal catheter, which proved to be a sufficient measure in almost all patients (52/55). Other adverse events (i.e., inadequate sedative plan, pain, and bradycardia) accounted for 2.6% of cases (4/153). Conclusions: Non-intubated GA in the prone position may be regarded as a safe procedure, as long as the anesthesiological criteria of exclusion are respected and the anesthesiological team has become acquainted with the peculiar NORA setting and familiar with the management of possible adverse events.
