分析国产机器人辅助食管裂孔疝修补联合胃底折叠术在动物模型中实施的可行性。

2024年7月为2只实验猪行机器人辅助食管裂孔疝修补联合胃底折叠术，每只实验猪分别依次进行Nissen（360°）和Toupet（270°）胃底折叠术2种术式。记录每只实验猪在每次手术中的手术时间、出血量以及2次手术中的装机时间和拆机时间。

术中动物生命体征平稳，无术中大出血等严重并发症发生。实验猪A和实验猪B的Nissen胃底折叠术手术时间分别为145.0 min和151.6 min，Toupet胃底折叠术的手术时间分别为150.0 min和168.4 min。在2次手术中国产机器人系统的装机时间分别为10.0 min和10.5 min，拆机时间分别为5.0 min和5.5 min。2只实验猪的术中出血量分别为52.0 ml和56.7 ml。2只实验猪均顺利完成手术，术中术后无死亡案例。

国产机器人辅助食管裂孔疝修补联合胃底折叠术在猪动物模型中的初步应用显示其具备可行性及手术安全性，为后续复杂术式及大样本训练提供了参考。

To investigate the feasibility of domestic robotic-assisted hiatal hernia repair combined with fundoplication in an animal model.

Two pigs were selected as experimental subjects and underwent robotic-assisted hiatal hernia repair in July 2024. Both Nissen (360°) and Toupet (270°) fundoplication were performed on each pig. The surgical time, blood loss, robot setup and teardown time were recorded for each procedure.

During the surgery, the animals’ vital signs were stable, and no serious complications such as massive bleeding occurred. The surgical time for Nissen fundoplication was 145.0 min and 151.6 min in pig A and pig B, respectively, and for Toupet fundoplication was 150.0 min and 168.4 min in pig A and pig B, respectively. The robot setup time was 10.0 min and 10.5 min, and the teardown time was 5.0 min and 5.5 min, respectively. The intraoperative blood loss was 52.0 ml and 56.7 ml, respectively. Both pigs successfully completed the surgery without any mortality during or after the procedure.

The preliminary application of domestic robot-assisted hiatal hernia repair combined with fundoplication in a porcine animal model shows that it is feasible and surgically safe, providing a reference for subsequent complex surgical procedures and large-sample training.
