Laparoscopic Pancreatoduodenectomy in Elderly Patients: A Systematic Review and Meta-Analysis.

Background and Aims: Recent single-center retrospective studies have focused on laparoscopic pancreatoduodenectomy (LPD) in elderly patients, and compared the outcomes between the laparoscopic and open approaches. Our study aimed to determine the outcomes of LPD in the elderly patients, by performing a systematic review and a meta-analysis of relevant studies. Methods: A comprehensive literature review was conducted utilizing the Embase, Medline, PubMed, Scopus and Cochrane databases to identify all studies that compared laparoscopic vs. open approach for pancreatoduodenectomy (PD). Results: Five retrospective studies were included in the final analysis. Overall, 90-day mortality rates were significantly decreased after LPD in elderly patients compared with open approaches (RR = 0.56; 95%CI: 0.32−0.96; p = 0.037, I2 = 0%). The laparoscopic approach had similar mortality rate at 30-day, readmission rate in hospital, Clavien−Dindo complications, pancreatic fistula grade B/C, complete resection rate, reoperation for complications and blood loss as the open approach. Additionally, comparing with younger patients (<70 years old), no significant differences were seen in elderly cohort patients regarding mortality rate at 90 days, readmission rate to hospital, and complication rate. Conclusions: Based on our meta-analysis, we identify that LPD in elderly is a safe procedure, with significantly lower 90-day mortality rates when compared with the open approach. Our results should be considered with caution, considering the retrospective analyses of the included studies; larger prospective studies are required.
