腹腔镜下经膈肌裂孔食管胃切除治疗食管胃交界癌55例

Laparoscopic transhiatal extended gastrectomy for type Ⅱ,Ⅲ esophagogastric junction cancer： a preliminary report of 55 cases

目的 探讨腹腔镜下经膈肌裂孔食管胃切除术治疗食管胃交界癌的安全性和可行性.方法 回顾性分析2008年2月至2010年5月接受腹腔镜下经膈肌裂孔食管胃切除术治疗的55例食管胃交界癌患者的临床资料.结果 本组患者中Siewert Ⅱ型者36例,Siewert Ⅲ型者19例;行近端胃大部切除35例,全胃切除术20例;行D2淋巴结清扫53例,姑息性切除2例;行下纵隔食管旁淋巴结清扫或活检33例.5例患者中转开腹,其余50例顺利完成腹腔镜手术,手术时间（236.2±35.5） min,出血量（60.6±33.9） ml,清扫淋巴结（21.2±10.4）枚,食管切缘距肿瘤近端平均（3.5±0.7） cm.无围手术期死亡病例,无吻合口狭窄或瘘发生.术中纵隔淋巴结清扫过程中11例患者出现胸膜破裂,其中6例于术中及时修补,4例于手术结束前修补,1例于术后行胸腔穿刺,均顺利恢复.术后肺部感染3例,切口感染1例.结论 腹腔镜下经膈肌裂孔食管胃切除治疗食管胃交界癌安全可行.

Objective To explore the feasibility and safety of laparoscopic extended gastrectomy through the transhiatal approach in patients with esophagogastric junction cancer. Methods From Feb 2008 to May 2010, 55 cases with Siewert type Ⅱ or Ⅲ esophagogastric junction cancer underwent laparoscopic transhiatal extended gastrectomy at the West China hospital. Clinical data were analyzed retrospectively. Results Esophagogastric junction cancer was Siewert type Ⅱ in 36 patients and Siewert type Ⅲ in 19. Thirty-five cases underwent proximal gastrectomy, 20 total gastrectomy. There were 53 D2 lymph node excisions and 2 palliative resections. Fifty patients underwent laparoscopic extended gastrectomy successfully, with 5 converted to open operations. A safe anastomosis between inferior pulmonary vein and pulmonary hilum was achieved in the majority of patients. The mean operative time was（236.2±35.5） min and the mean estimated blood loss was（60.6±33.9） ml. There were no postoperative mortalities or anastomotic leakage/stenosis. No reoperations were required. Pleural laceration occurred in 11 cases during operation, of whom 10 were repaired intraoperatively and one was managed with drainage postoperatively. There were 3 patients developed pulmonary infection and one wound infection. Postoperative recovery was uneventful in other patients. Conclusion Laparoscopic transhiatal extended gastrectomy is feasible and safe for patients with esophagogastric junction cancer.
