Pancreaticoduodenectomy with major vascular resection: a comparison of laparoscopic versus open approaches

Major vascular resection when necessary for margin control during pancreaticoduodenectomy is relatively universal with perioperative and oncological outcomes that are similar to those of patients undergoing a PD without venous involvement. The present study compares total laparoscopic pancreaticoduodenectomy (TLPD) versus open pancreaticoduodenectomy (OPD) with major vascular resection.

We reviewed data for all patients undergoing TLPD or OPD with vascular resection at Mayo Clinic Rochester, between the dates of July 2007 and July 2013.

A total of 31 patients undergoing TLPD and 58 patients undergoing OPD with major vascular resection were identified. Mean operative blood loss was significantly less in the laparoscopic (842 cc) compared to the open group (1,452 cc) (p < 0.001), as was median hospital stay, 6 (4-118) versus 9 (6-73) days, respectively (p = 0.006). There was no significant difference in the total number of complications (lap 35%, open 48%) (p = 0.24) or severe complications (≥III) (lap 6.4%, open 3.4%) (p = 0.51) in the two groups. In-hospital mortality or 30-day mortality was not statistically different between the laparoscopic and open groups, 3.2 and 3.4%, respectively (p = 0.96). Patency of the reconstructed vessels on postoperative imaging was not significantly different between the TLPD (93%) and OPD groups (91%) (p = 0.76). In patients with a diagnosis of adenocarcinoma, there was no significant difference in overall survival between the two groups (p = 0.22).

The present study clearly demonstrates that not only is TLPD with major vascular resection feasible and safe but that it can achieve results that are similar in morbidity and mortality as well as oncologic outcome compared to patients undergoing OPD with major vascular resection.
