Objective: To compare and analyze the perioperative clinical effects of minimally invasive Ivor-Lewis esophagectomy (MIE-Ivor-Lewis) and minimally invasive McKeown esophagectomy (MIE-McKeown). Methods: A total of 147 patients who underwent endoscopic esophageal cancer surgery from April 2018 to August 2019 were selected, including 85 patients undergoing MIE-McKeown surgery and 62 patients undergoing MIE-Ivor-Lewis surgery. The measurement data were expressed as (x±s), the comparison of normally distributed measurement data was performed by independent sample t-test, and the comparison of count data was performed by χ(2) test or Fisher\'s exact test. Results: The operation time of McKeown (M) group and Ivor-Lewis (IL) group were (219.2±72.4) minutes and (225.8±65.3) minutes. The mediastinal lymph node dissection number of M and IL groups were 13.3±4.8 and 11.6±6.5, respectively. The number of left recurrent laryngeal nerve lymph node dissection were 3.5±1.2 and 3.1±1.4, respectively. The intraoperative blood loss were (178.3±41.3) ml and (163.2±64.1) ml, respectively. The number of patients reoperated for postoperative bleeding were 1 and 0, respectively. The number of patients with postoperative gastric bleeding were 0 and 1, respectively. The postoperative chest tube retention time were (2.8±1.3) days and (3.1±1.2) days, respectively. The number of patients with anastomotic leakage were 7 and 1, respectively. The number of patients with lung infection were 13 and 5, respectively, and with chylothorax were 2 and 1, respectively, without statistically significant difference (P>0.05). The number of patients with hoarseness were 11 and 3, respectively. The total incidence of complication were 41.2% (35/85) and 17.7% (11/62), and the postoperative hospital stay were (14.7±6.5) days and (12.3±2.3) days, with statistical difference (P<0.05). Conclusion: MIE-Ivor-Lewis and MIE-McKeown are safe and effective in treating esophageal cancer, but the complication of MIE-Ivor-Lewis is less than that of MIE-Mckeown, and the perioperative clinical effect of MIE-Ivor-Lewis is better than that of MIE-McKeown.
目的： 探讨微创Ivor-Lewis(MIE-Ivor-Lewis)与微创McKeown(MIE-McKeown)术式治疗食管癌的围手术期临床效果。 方法： 选取2018年4月至2019年8月于东南大学附属中大医院接受全腔镜食管癌根治术患者147例，MIE-McKeown手术(McKeown组)患者85例，MIE-Ivor-Lewis手术(Ivor-Lewis组)患者62例。计量资料以(x±s)表示，呈正态分布的计量资料的比较采用独立样本t检验，计数资料的比较采用χ(2)检验或Fisher精确检验。 结果： McKeown组和Ivor-Lewis组患者手术时间[分别为(219.2±72.4)min和(225.8±65.3)min]、纵隔淋巴结清扫数[分别为(13.3±4.8)枚和(11.6±6.5)枚]、左喉返淋巴结清扫数[分别为(3.5±1.2)枚和(3.1±1.4)枚]、术中出血量[分别为(178.3±41.3)ml和(163.2±64.1)ml]、术后出血再手术患者数(分别为1和0例)、术后胃出血患者数(分别为0和1例)、术后胸管留置时间[分别为(2.8±1.3)d和(3.1±1.2)d]、吻合口瘘患者数[分别为7和1例]、肺部感染患者数(分别为13和5例)和乳糜胸患者数(分别为2和1例)差异均无统计学意义(均P>0.05)。McKeown组和Ivor-Lewis组患者声音嘶哑[分别为11和3例]、总并发症发生率[分别为41.2%(35/85)和17.7%(11/62)]和术后住院时间[分别为(14.7±6.5)d和(12.3±2.3)d]差异均有统计学意义(均P<0.05)。 结论： MIE-Ivor-Lewis术与MIE-McKeown术治疗食管癌安全有效，但MIE-Ivor-Lewis术较MIE-Mckeown术并发症少，MIE-Ivor-Lewis术围手术期临床效果优于MIE-McKeown术。.

OBJECTIVE: To introduce a two-step method for creating a gastric tube during laparoscopic-thoracoscopic Ivor-Lewis esophagectomy and assess its clinical application.
METHODS: One hundred and twenty-two patients with middle or lower esophageal cancer who underwent laparoscopic-thoracoscopic Ivor-Lewis esophagectomy at Liaoning Cancer Hospital and Institute from March 2014 to March 2016 were included in this study, and divided into two groups based on the procedure used for creating a gastric tube. One group used a two-step method for creating a gastric tube, and the other group used the conventional method. The two groups were compared regarding the operating time, surgical complications, and number of stapler cartridges used.
RESULTS: The mean operating time was significantly shorter in the two-step method group than in the conventional method group [238 (179-293) min vs 272 (189-347) min, P < 0.01]. No postoperative death occurred in either group. There was no significant difference in the rate of complications [14 (21.9%) vs 13 (22.4%), P = 0.55] or mean number of stapler cartridges used [5 (4-6) vs 5.2 (5-6), P = 0.007] between the two groups.
CONCLUSIONS: The two-step method for creating a gastric tube during laparoscopic-thoracoscopic Ivor-Lewis esophagectomy has the advantages of simple operation, minimal damage to the tubular stomach, and reduced use of stapler cartridges.
