Subtotal oesophagectomy and stapled oesophagogastric anastomosis is a favoured option for cure or palliation of oesophageal carcinoma. This approach currently involves a thoracotomy and laparotomy exposing the patient to the attendant pulmonary and intrathoracic complications. Alternative approaches to oesophagectomy without thoracotomy have failed to diminish the complication rate and may compromise the chance of cure. An endoscopic approach to the oesophagus is considered to be an evolving solution because it removes the need for thoracotomy and laparotomy but adheres to established oncologic principles. In order to assess the feasibility of complete endosurgical oesophagectomy and immediate reconstruction a non-survival study using 10 pigs was undertaken. Under general anaesthesia a 3-step operation was performed consisting of thoracoscopic oesophageal dissection, laparoscopic gastric mobilisation and thoracoscopic oesophagogastric anastomosis using a circular endoluminal stapler (Stealth-Ethicon). Conversion to open surgery was required only once during a gastric dissection, and all anastomoses were safely constructed thoracoscopically. In three animals small anastomotic tears were repaired with endoscopically-placed sutures. Three animals died intraoperatively, two from an anaesthetic complication prior to the introduction of intra-operative monitoring, and the other following haemorrhage from an hepatic vein traumatised by a liver retractor. This study has shown that endosurgical oesophagectomy is technically feasible and stapled oesophagogastric anastomosis can be performed in a comparable manner to the conventional procedure.
食管次全切除术及吻合器食管胃吻合术是治疗或缓解食管癌的一种常用方法。目前这种方法需要开胸和开腹手术,使患者面临随之而来的肺部和胸腔内并发症。不进行开胸手术的替代食管切除方法未能降低并发症发生率,且可能会影响治愈的机会。内镜下食管手术被认为是一种不断发展的解决方案,因为它无需开胸和开腹手术,但遵循既定的肿瘤学原则。为了评估完全内镜下食管切除术及即时重建的可行性,我们使用10头猪进行了一项非生存性研究。在全身麻醉下进行了一个三步手术,包括胸腔镜下食管解剖、腹腔镜下胃游离以及使用圆形腔内吻合器(Stealth-Ethicon)进行胸腔镜下食管胃吻合术。在一次胃游离过程中仅需转为开放手术一次,所有吻合术均通过胸腔镜安全完成。在三只动物中,小的吻合口撕裂通过内镜放置缝线进行了修复。三只动物在术中死亡,两只死于引入术中监测之前的麻醉并发症,另一只死于肝脏牵开器损伤肝静脉导致的出血。这项研究表明,内镜下食管切除术在技术上是可行的,且吻合器食管胃吻合术可以以与传统手术相当的方式进行。
