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

Background: 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.

Methods: 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.

[Repeated tissue expansion for repairing extensive scalp and facial soft tissue defects: analysis of 18 cases].

Objective: To summarize our experiences with 18 cases of repeated tissue expansion for treating extensive scalp and facial soft tissue defects.

Method: Tissue expansion was performed for 1 or 2 times after the primary expansion for repairing large scalp and facial soft tissue defects ranging from 9 cm x 5 cm to 16 cm x 12 cm using re-expanded flaps. The indications, complications and experiences in the treatment were discussed.
