Robotic versus laparoscopic distal pancreatectomies: A systematic review and meta‐analysis on costs and perioperative outcome

摘要

AIM: The aim of this meta-analysis is to compare perioperative outcomes and costs of robotic and laparoscopic distal pancreatectomy (RDP and LDP). MATERIAL AND METHODS: In accordance with the PRISMA guidelines, we searched Medline, EMBASE, Cochrane and Web of Science for reports published before December 2020. RESULTS: The literature search identified 11 papers (1 187 patients). RDP showed a lower conversion rate (odds ratio: 2.56, 95% confidence intervals [CI]: 1.31 to 5.00) with no significant differences in bleeding and operative time, complications ≥ Clavien-Dindo grade III, pancreatic fistulas and length of stay. Despite RDP presenting higher costs in all included studies, none of these differences were significant. However, RDP showed higher total costs than LDP (standardized mean differences [SMD]: -1.18, 95% CI: -1.97 to -0.39). A subgroup analysis according to the continent of origin showed that studies coming from Asian research groups kept showing significant differences (SMD: -2.62, 95% CI: -3.38 to -1.85), while Western groups did not confirm these findings. CONCLUSION: Based on low-quality evidence, despite some potential technical advantages, RDP still seems to be costlier than LDP.
