Objective To systematically evaluate the efficacy and safety of thoraco-laparoscopy combined with Ivor Lewis surgery versus thoraco-laparoscopy combined with McKeown surgery in the treatment of esophageal carcinoma. MethodsPubMed, EMbase, The Cochrane Library, Web of Science, Wanfang database, VIP database and CNKI were searched by computer for the relevant literature comparing the efficacy and safety of Ivor Lewis surgery and McKeown surgery in the treatment of esophageal carcinoma from inception to January 2022. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of cohort studies, and the Cochrane risk of bias tool was used to evaluate the methodological quality of randomized controlled studies. Review Manager 5.4 software was utilized to perform a meta-analysis of the literature. ResultsA total of 33 articles were included, which consisted of 26 retrospective cohort studies, 3 prospective cohort studies and 4 randomized controlled trials. There were 11 518 patients in total, including 5 454 patients receiving Ivor Lewis surgery and 6064 patients receiving McKeown surgery. NOS score was≥7 points. Meta-analysis showed that, in comparison to the McKeown surgery, the Ivor Lewis surgery had shorter operative time (MD=–19.61, 95%CI –30.20 to –9.02, P<0.001), shorter postoperative hospital stay (MD=–1.15, 95%CI –1.43 to –0.87, P<0.001), lower mortality rate during hospitalization or 30 days postoperatively (OR=0.37, 95%CI 0.20 to 0.71, P=0.003), and lower incidence of total postoperative complications (OR=0.36, 95%CI 0.27 to 0.49, P<0.001). The McKeown surgery had an advantage in terms of the number of lymph nodes dissected (MD=–1.25, 95%CI –2.03 to –0.47, P=0.002), postoperative extubation time (MD=0.78, 95%CI 0.37 to 1.19, P<0.001) and 6-month postoperative recurrence rate (OR=1.83, 95%CI 1.41 to 2.39, P<0.001). The differences between the two surgeries were not statistically significant in terms of intraoperative bleeding, postoperative 1 year-, 3 year- and 5 year-overall survival (OS), and impaired gastric emptying (P>0.05). ConclusionCompared with McKeown surgery, Ivor Lewis surgery has shorter operative time, shorter postoperative hospital stay, lower mortality rate during hospitalization or 30 days postoperatively and lower incidence of total postoperative complications. However, in terms of the number of lymph nodes dissected, postoperative extubation time and 6-month postoperative recurrence rate, McKeown surgery has advantages. Both surgeries have comparable results in terms of intraoperative bleeding, postoperative 1 year-, 3 year- and 5 year-OS, and impaired gastric emptying.
