The short-term and long-term outcomes were compared between the LTG(n = 382) and OTG(n = 196) groups.RESULTS Compared with the OTG group, the LTG group had a longer operative time but less blood loss, shorter length of abdominal incision and an increased number of harvested lymph nodes(P < 0.05). Patients in the LTG group were able to eat liquid food, ambulate, expel flatus and discharge sooner than the OTG group(P < 0.05). No significant differences were found in postoperative complications and R0 resection. The 3-year overall survival and disease-free survival performed better in the LTG group compared with that in the OTG group(88.2% vs 79.2%, P = 0.011;79.7% vs 73.0%, P = 0.002, respectively). In the stratified analysis, both overall survival and disease-free survival were better in the LTG group than those in the OTG group for stage Ⅱ/Ⅲ patients(P < 0.05) but not for stage I patients.CONCLUSION For patients with Siewert type Ⅱ AEG, LTG is associated with better short-term outcomes and similar oncology safety. In addition, patients with advanced stage AEG may benefit more from LTG in the long-term outcomes.展开更多

文摘目的探讨经右胸入路的Ivora-Lewis(IL)和经左胸入路的左开胸(left transthoraeie,LTI)、左胸腹联合(1eftthoracoabdominal,LTA)3种手术方式在SiewertⅡ型食管胃交界部腺癌(adenocar-cinoma of the esophagogastric junction, AEG)中的应用。方法回顾性分析2014年1月至2016年4月于天津医科大学肿瘤医院食管肿瘤科行手术切除的196例SieweⅡ/型AEG患者的临床病理资料,符合入组条件的136例纳入研究。根据手术方式分为IL组(47例)、LTT组(51例)和LTA组(38例)。采用方差分析0检验和Fisher确切概比例法比较3组患者的临床病理资料及近期疗效,包括手术时间及出血量,近端切缘长度,淋巴结清扫程度,术后死亡及并发症等方面的差异。结果岍组有合并体质量下降、糖尿病和心脏疾病增多的趋势(P=0.054,P=0.075及P=0.063)。IL组手术时间长于LTT组和LTA组(223.8min对149.2min对166.2min,P=0.000),但出血量3组间差异无统计学意义(P=0.176)。3组肿瘤大小差异无统计学意义(P=0.228),但IL组离体近端切缘长度大于Ⅲ组和LTA组(3.8cm对2.4cm对1.9cm,P=0.000)。IL组总淋巴结清扫个数大于LTA组及哪组(21.2对14.3对10.7,P=0.000),IL组胸腔淋巴结清扫个数大于LTT组及LTA组(7.8对2.6对1.0,P=0.000),IL组和LTA组腹腔淋巴结清扫个数大于LTT(13.7对13.3对8.0,P=0.000)。IL组胸腔各站淋巴结清扫比例高于LTT组和LTA组(P〈0.05),LTT组下纵隔各站淋巴结清扫比例高于LTA组(P〈0.05);3组贲门旁、胃左动脉旁及胃小弯淋巴结清扫比例差异无统计学意义(P〉0.05),但IL组肝动脉旁、脾动脉旁及腹腔干淋巴结清扫比例高于LTT组及LTA组(P〈0.05)。3组患者在术后住院天数、围手术期并发症及死亡比例方面差异均无统计学意义(P〉0.05)。结论经右胸入路的Ivor—Lewis术较传统的经左胸入路不会增加SiewertII型AEG围手术期死亡及并发症的发生比例,获得满意的近端切缘长度,且对于胸、腹腔淋巴结清扫优于经左胸入路,有待进一步随访及前瞻性随机对照试验验证。
