Natural orifice transluminal endoscopic surgery (NOTES) is a new technique. This study describes our initial experience of NOTES and investigates the feasibility of transumbilical endoscopic cholecystectomy (TUEC).
Eight domestic pigs were submitted to TUEC. After establishment of pneumoperitoneum, a bi-channel endoscope was placed through an infra-umbilical trocar. The gallbladder fundus was lifted by a grasper. The cystic duct and artery was dissected with a flexible hook and clipped by a clip fixing device. The specimen was extracted through the infra-umbilical trocar.
The mean operation time was 114 minutes, ranging from 75 to 155 minutes. All the gallbladders were removed successfully. There was one case of subtotal resection, two cases of bleeding and three cases of bile leakage.
Transumbilical endoscopic cholecystectomy is feasible although it needs more support of experiments and techniques before being applied on human subjects.
自然腔道内镜手术（NOTES）是一项新技术。本研究描述了我们NOTES的初步经验，并探讨经脐内镜胆囊切除术（TUEC）的可行性。
对8头家猪实施TUEC。建立气腹后，通过脐下套管置入双通道内镜。用抓钳提起胆囊底部。用柔性钩分离胆囊管和动脉，并用夹固定装置夹闭。标本通过脐下套管取出。
平均手术时间为114分钟，范围为75至155分钟。所有胆囊均成功切除。有1例次全切除，2例出血，3例胆漏。
经脐内镜胆囊切除术是可行的，尽管在应用于人体之前还需要更多的实验和技术支持。
