RESUMO
OBJECTIVE: Assessment of minimally invasive pancreatoduodenectomy (MIPD) in patients with pancreatic ductal adenocarcinoma (PDAC) is scarce and limited to non-randomized studies. This study aimed to compare oncological and surgical outcomes after MIPD compared to open pancreatoduodenectomy (OPD) for patients after resectable PDAC from published randomized controlled trials (RCTs). METHODS: A systematic review was performed to identify RCTs comparing MIPD and OPD including PDAC (Jan 2015-July 2021). Individual data of patients with PDAC were requested. Primary outcomes were R0 rate and lymph node yield. Secondary outcomes were blood-loss, operation time, major complications, hospital stay and 90-day mortality. RESULTS: Overall, 4 RCTs (all addressed laparoscopic MIPD) with 275 patients with PDAC were included. In total, 128 patients underwent laparoscopic MIPD and 147 patients underwent OPD. The R0 rate (risk difference(RD) -1%, P = 0.740) and lymph node yield (mean difference(MD) +1.55, P = 0.305) were comparable between laparoscopic MIPD and OPD. Laparoscopic MIPD was associated with less perioperative blood-loss (MD -91ml, P = 0.026), shorter length of hospital stay (MD -3.8 days, P = 0.044), while operation time was longer (MD +98.5 min, P = 0.003). Major complications (RD -11%, P = 0.302) and 90-day mortality (RD -2%, P = 0.328) were comparable between laparoscopic MIPD and OPD. CONCLUSIONS: This individual patient data meta-analysis of MIPD versus OPD in patients with resectable PDAC suggests that laparoscopic MIPD is non-inferior regarding radicality, lymph node yield, major complications and 90-day mortality and is associated with less blood loss, shorter hospital stay, and longer operation time. The impact on long-term survival and recurrence should be studied in RCTs including robotic MIPD.
