【摘要】:AIM:To explore the technique for laparoendoscopic single-site distal pancreatectomy.METHODS:Laparoendoscopic single-site spleenpreserving 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.RESULTS:Six pigs were involved in this study,and five survived the procedure.The first animal died following injury to the superior mesenteric vein and uncontrolledintraoperative 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.CONCLUSION:Laparoendoscopic single-site distal pancreatectomy is a safe and feasible procedure and can be implemented in humans in selected cases at qualified surgical centers.
