The Gastro-Laryngeal Tube (G-LT) is a modification of the laryngeal tube which provides a dedicated channel for the insertion of an endoscope while acting as a supraglottic airway for ventilation. The aim of this study was to assess the safety and effectiveness of this device in patients undergoing anesthesia for interventional endoscopic biliopancreatic procedures (IEBPPs).A total of 22 patients were included in the study. The G-LT was inserted successfully in all patients. Arterial oxygen saturation was stable; the mean value was 97.9%. The IEBPPs were performed successfully in all patients through the endoscopic channel, with a mean duration of 99 minutes. The maneuverability of the endoscope was considered good in all patients. There were two cases of sore throat after the procedures, two cases of asymptomatic erosion of the upper esophageal mucosa, one case of Mallory-Weiss syndrome, and one case of pancreatitis after endoscopic retrograde cholangiopancreatography.Our results suggest that the G-LT is an effective and secure device for airway management and for use during IEBPPs.
胃喉管（G-LT）是喉管的一种改良，它提供了一个专门的通道，可插入内镜，同时作为声门上气道进行通气。本研究旨在评估该设备在接受介入性内镜胆胰管手术（IEBPP）麻醉的患者中的安全性和有效性。
共有 22 名患者纳入本研究。所有患者均成功插入 G-LT。动脉血氧饱和度稳定，平均值为 97.9%。所有患者均通过内镜通道成功完成 IEBPP，平均持续时间为 99 分钟。所有患者均认为内镜的操作性良好。术后有 2 例咽痛，2 例无症状性食管上段黏膜侵蚀，1 例 Mallory-Weiss 综合征，1 例内镜逆行胰胆管造影术后胰腺炎。
我们的结果表明，G-LT 是一种有效和安全的气道管理和 IEBPP 期间使用的装置。
