1995年11月至1996年12月间,接连收集50例食管癌病人进行前瞻性研究。男性39例,女性11例,平均年龄58(31～81)岁。36例病人诊为远段食管或贲门腺癌,14例病人诊为食管下1/3段鳞癌。所有病人都经包括有腹部超声波与胸、腹部CT术前分期检查。在预定手术切除同时,全麻下施行腹腔镜检查,腹腔内置入Veress针并给以CO_2充气,脐上插入腹腔镜。大多数病例使用30°视角腹腔镜,上腹部再插入1～2枚套针以便处理内脏并对腹膜腔进行冲洗和抽吸,腹腔内
Between November 1995 and December 1996, 50 patients with esophageal cancer were collected and prospectively studied. There were 39 males and 11 females with an average age of 58 (31-81) years. Thirty-six patients were diagnosed as distal esophageal or cardiac adenocarcinomas, and 14 patients were diagnosed as lower 1/3 squamous cell carcinoma of the esophagus. All patients included preoperative staging of abdominal ultrasound, chest, and abdomen CT. At the same time as scheduled resection, laparoscopy was performed under general anesthesia. The Veress needle was placed in the abdominal cavity and CO 2 was inflated. The laparoscope was inserted into the umbilicus. In most cases, a laparoscope with a 30° angle of view is used, and 1 to 2 trocars are inserted into the upper abdomen to treat the viscera. The peritoneal cavity is rinsed and aspirated intraperitoneally.
