Hind Right Approach Pancreaticoduodenectomy : From Skill to Indications

Abstract EN

Background.

Pancreaticoduodenectomy is the potentially curative treatment for malignant and several benign conditions of the pancreatic head and periampullary region.

While performing pancreaticoduodenectomy, early neck division may be impossible or inadequate in case of hepatic artery anatomic variants, suspected involvement of the superior mesenteric vessels, intraductal papillary mucinous neoplasm, and pancreatic head bleeding pseudoaneurysm.

Our work aims to highlight a particular hind right approach pancreaticoduodenectomy in selected indications and assess the preliminary results.

Methods.

We describe our early hind right approach to the retropancreatic vasculature during pancreaticoduodenectomy by mesopancreas dissection before any pancreatic or digestive transection.

Results.

We used this approach in 52 patients.

Thirty-two had hepatic artery anatomic variant and 2 had bleeding pancreatic head pseudoaneurysm.

The hepatic artery variant was preserved in all cases out of 2 in which arterial reconstruction was performed.

In nine patients with intraductal papillary mucinous neoplasms the pancreaticoduodenectomy was extended to the body in 6 and totalized in 3 patients.

Seven patients with adenocarcinoma involving the portomesenteric axis required venous resection and reconstruction.

Conclusions.

Early hind right approach is advocated in selected cases of pancreaticoduodenectomy to improve locoregional vascular control and determine, safely and early, whether there is mesopancreas involvement.
