Robotic versus laparoscopic left colectomy: a systematic review and meta-analysis
Abstract
This study aimed to review the new evidence to understand whether the robotic approach could find some clear indication also in left colectomy. A systematic review of studies published from 2004 to 2022 in the Web of Science, PubMed, and Scopus databases and comparing laparoscopic (LLC) and robotic left colectomy (RLC) was performed. All comparative studies evaluating robotic left colectomy (RLC) versus laparoscopic (LLC) left colectomy with at least 20 patients in the robotic arm were included. Abstract, editorials, and reviews were excluded. The Newcastle–Ottawa Scale for cohort studies was used to assess the methodological quality. The random-effect model was used to calculate pooled effect estimates. Among the 139 articles identified, 11 were eligible, with a total of 52,589 patients (RLC, n = 13,506 versus LLC, n = 39,083). The rate of conversion to open surgery was lower for robotic procedures (RR 0.5, 0.5–0.6; p < 0.001). Operative time was longer for the robotic procedures in the pooled analysis (WMD 39.1, 17.3–60.9, p = 0.002). Overall complications (RR 0.9, 0.8–0.9, p < 0.001), anastomotic leaks (RR 0.7, 0.7–0.8; p < 0.001), and superficial wound infection (RR 3.1, 2.8–3.4; p < 0.001) were less common after RLC. There were no significant differences in mortality (RR 1.1; 0.8–1.6, p = 0.124). There were no differences between RLC and LLC with regards to postoperative variables in the subgroup analysis on malignancies. Robotic left colectomy requires less conversion…
