Objectives: Minimally invasive cyst excision and Roux-en-Y hepaticojejunostomies include laparoscopic and robotic-assisted operations. The current systematic review and meta-analysis compared the efficacy between the 2 groups.
Methods: A systematic search of PubMed, Web of Science, Embase, Wiley, Cochrane Library and Clinical Trials was performed from May 1995 to December 2021. The primary outcome was postoperative complications, and the secondary outcomes were operative details and postoperative outcomes.
Results: The meta-analysis enrolled 6 reports including 484 patients (307 in the laparoscopic group and 177 in the robotic-assisted group). The laparoscopic group was associated with lower expenses (MD = -3851.60$, 95% CI = -4031.84 to -3671.36$, P < 0.00001). No significant difference was found in short-term complications (RR = 1.55, 95% CI = 0.74 to 3.23, P = 0.24), long-term complications (RR = 1.40, 95% CI = 0.63 to 3.10, P = 0.41), total complications (RR = 1.53, 95% CI = 0.59 to 3.94, P = 0.38), operative time (MD = -28.75 min, 95% CI = -77.13 to 19.64 min, P = 0.24), blood loss (MD = 2.28 ml, 95% CI = -13.51 to 18.06 ml, P = 0.78) or hospital stays (MD = 0.89 days, 95% CI = -0.13 to 1.91 days, P = 0.09). In subgroup analysis, the laparoscopic operation had shorter operative time (MD = -4.45 min, P = 0.009), and less blood loss (MD = -63.18 ml, P = 0.01) in adult patients.
Conclusions: Laparoscopic and robotic-assisted cyst excision and Roux-en-Y hepaticojejunostomy have comparable postoperative outcomes.
