To explore the technique for laparoendoscopic single-site distal pancreatectomy.
Laparoendoscopic single-site spleen-preserving distal pancreatectomy was performed in pigs using a novel flexible multichannel port, a curved laparoscopic multifunctional operative device and a fish hook retractor, which provided a favorable operative field.
Six pigs were involved in this study, and five survived the procedure. The first animal died following injury to the superior mesenteric vein and uncontrolled intraoperative bleeding. Except for this failure, the mean operative time was 155 min (range: 102-236 min). A steep learning curve was observed in the study, with a mean operative time of 177 min in the first two operations vs 134 min in the last three operations. The mean blood loss was 50 mL, and the postoperative course was uneventful. The animals were sacrificed three weeks after the procedures, and no pancreatic leakage or abdominal infection was found macroscopically.
Laparoendoscopic single-site distal pancreatectomy is a safe and feasible procedure and can be implemented in humans in selected cases at qualified surgical centers.
探索腹腔镜单孔远端胰腺切除术的技术。
使用新型柔性多通道端口、弯曲腹腔镜多功能手术器械和鱼钩牵开器对猪进行腹腔镜单孔保脾远端胰腺切除术，该器械提供了良好的手术视野。
本研究纳入6头猪，5头手术存活。第一只动物因肠系膜上静脉损伤和术中出血无法控制而死亡。除此次失败外，平均手术时间为155分钟（范围：102 - 236分钟）。研究中观察到学习曲线较陡，前两台手术平均手术时间为177分钟，后三台手术为134分钟。平均失血量为50毫升，术后过程平稳。术后三周处死动物，肉眼未发现胰漏或腹腔感染。
腹腔镜单孔远端胰腺切除术是一种安全可行的手术，在合格的手术中心，特定病例可在人体实施。
