Transthoracic esophagectomy remains the current therapeutic standard for localized esophageal carcinoma. Minimally invasive surgery has proven at least equivalent to open surgery regarding the early outcomes, but only 1 randomized study has compared the thoracoscopic with the thoracotomy approach. The primary objective of this study was to assess the early outcome of the thoracoscopic prone esophagectomy (TPE) and the hybrid Ivor Lewis (HIL) esophagectomy in 2 concurrent patient cohorts.
We compared the 1-year outcome of 3-stage TPE and 2-stage HIL done over the same time period in a single center. The propensity score matching method was used to reduce selection bias by creating 2 groups of patients similarly likely to receive a treatment on the basis of measured baseline characteristics. After generating propensity scores using the covariates of age, sex, body mass index, forced expiration volume at 1 second, Charlson comorbidity index, American Society of Anesthesiologists score, histologic tumor type, tumor site, pTNM stage, and neoadjuvant therapy, 93 TPE patients were matched with 197 HIL patients using a 1:1 ratio and the nearest-neighbor score matching. Main outcome measure was the incidence of postoperative complications.
Operative time was longer in TPE patients (P < .01). All postoperative outcomes, including morbidity, mortality, nodal harvest, R0 resection rate, and 1-year survival rates were similar in the 2 matched groups.
Both operative approaches are safe and effective; using 1 or the other depends on the tumor site, surgeon experience and preference, and patient expectations.
经胸食管切除术仍然是局限性食管癌当前的治疗标准。微创外科手术已被证明在早期疗效方面至少与开放手术相当,但仅有1项随机研究比较了胸腔镜手术与开胸手术方法。本研究的主要目的是评估在2个同期患者队列中胸腔镜俯卧位食管切除术(TPE)和改良Ivor Lewis(HIL)食管切除术的早期疗效。
我们比较了在同一中心同期进行的3阶段TPE和2阶段HIL的1年疗效。采用倾向评分匹配法,根据测量的基线特征创建2组接受治疗可能性相似的患者,以减少选择偏倚。在使用年龄、性别、体重指数、第1秒用力呼气量、Charlson合并症指数、美国麻醉医师协会评分、组织学肿瘤类型、肿瘤部位、pTNM分期和新辅助治疗等协变量生成倾向评分后,采用1:1比例和最近邻评分匹配法将93例TPE患者与197例HIL患者进行匹配。主要结局指标是术后并发症的发生率。
TPE患者的手术时间更长(P <.01)。2个匹配组的所有术后结局,包括发病率、死亡率、淋巴结清扫、R0切除率和1年生存率均相似。
两种手术方法均安全有效;选择使用哪种方法取决于肿瘤部位、外科医生的经验和偏好以及患者的期望。
