Management of the uncinate process via the artery first approach in laparoscopic pancreatoduodenectomy

Uncinate process dissection is one of the major challenges for surgeons when performing laparoscopic pancreatoduodenectomy. This study aimed to evaluate the artery first approach for handling uncinate process dissection in laparoscopic pancreatoduodenectomy.

Between February 2015 and June 2018, a total of 91 consecutive patients without vascular encasement underwent selective laparoscopic pancreatoduodenectomy, including the first 26 consecutive cases treated with the conventional approach and the remaining 65 with the artery first approach applied for uncinate process dissection. Here, we present and analyze the surgical outcomes and the oncological results for the two groups.

There was no significant difference between the two groups in operative time, intraoperative blood loss, the rate of conversion to open pancreatoduodenectomy, postoperative complications, mortality, as well as the number of lymph nodes retrieved in the malignancies. In contrast, the artery first approach group showed a statistically significant shorter resection time and a higher R0 resection rate when compared with the conventional group.

The artery first approach is a safe and feasible technique that can be used for uncinate process management in laparoscopic pancreatoduodenectomy for patients without vascular encasement. It also has the advantage of increased rate of radical resection in the surgical intervention of relevant malignancies.
