Abstract
Introduction: In order to compare the safety, efficacy, and oncological outcomes of laparoscopic (LC) and open colectomy (OC) for transverse colon cancer (TCC) patients, the present systematic review of the literature and meta-analysis was designed. Methods: This study was conducted following the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. A systematic screening of the electronic databases was performed (Medline, Web of Science and Scopus). The validity of the pooled results was verified through the performance of trial sequential analysis (TSA). The level of evidence was estimated using the GRADE approach. Results: Overall, 21 studies and 2498 patients were included in our study. Pooled comparisons and TSA analyses reported a superiority of LC over OC in terms of postoperative complications (OR 0.64, p = 0.0003), blood loss (WMD − 86.84, p < 0.00001), time to first flatus (WMD − 0.94, p < 0.00001) and oral diet (WMD − 1.25, p < 0.00001), and LOS (WMD − 2.39, p < 0.00001). Moreover, OC displayed a lower operation duration (p < 0.00001). A higher rate of complete mesocolic excision (p = 0.001) was related to OC. Although inconclusive in TSA, the recurrence rate in LC group was lower. LC and OC were equivalent in terms of postoperative survival outcomes. Conclusions: Considering several limitations of the eligible studies and the subsequent low level of evidence, further RCTs of a higher quality and methodological level are required to verify the findings of our meta-analysis. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.
