Total laparoscopic pancreaticoduodenectomy for pancreatic ductal adenocarcinoma oncologic advantages over open approaches?

Objective: To directly compare the oncologic outcomes of TLPD and OPD in the setting of pancreatic ductal adenocarcinoma.

Background: Total laparoscopic pancreaticoduodenectomy (TLPD) has been demonstrated to be feasible and may have several potential advantages over open pancreaticoduodenectomy (OPD), including lower blood loss and shorter hospital stay.Whether potential advantages could allow patients to recover in a timelier manner and pursue adjuvant treatment options remains to be answered.

Methods: We reviewed data for all patients undergoing TLPD (N = 108) or OPD (N = 214) for pancreatic ductal adenocarcinoma at our institution between January 2008 and July 2013.

Results: Neoadjuvant therapy, tumor size, node positivity, and marginpositive resection were not significantly different between the 2 groups. Median length of hospital stay was significantly longer in the OPD group (9 days; range, 5-73 days) than in the TLPD group (6 days; range, 4-118 days; P 0.001). There was a significantly higher proportion of patients in the OPD group (12%) who had a delay of greater than 90 days or who did not receive adjuvant chemotherapy at all compared with that in the TLPD group (5%; P = 0.04). There was no significant difference in overall survival between the 2 groups (P = 0.22). A significantly longer progressionfree survival was seen in the TLPD group than in the OPD group (P = 0.03).

Conclusions: TLPD is not only feasible in the setting of pancreatic ductal adenocarcinoma but also has advantages such as shorter hospital stay and faster recovery, allowing patients to recover in a timelier manner and pursue adjuvant treatment options. This study also demonstrated a longer progressionfree survival in patients undergoing TLPD than those undergoing OPD.
