Reconstruction of composite defects of the posterior thigh and knee is challenging. Pedicled medial gastrocnemius flaps are the traditional reconstructive approach, but late contractures related to skin grafted muscle may affect knee function. More recently, the medial sural artery perforator (MSAP) flap has been described for such defects, although may necessitate skin grafting of the donor site. To minimise the drawbacks with these options, we describe a combination of a median superficial sural artery perforator (MSSAP) flap and MSAP flap. This allows both tension free closure of the donor site without skin grafting, and facilitates coverage of a round defect by splitting the flap into two adjacent triangular flaps. This is the first report of posterior thigh defect reconstruction with a combination of MSSAP and MSAP flaps.

Fluorescence imaging in colorectal surgery is considered a novel predominantly intraoperative method of ensuring a greater surgical success. The use of fluorescence is linked to advanced tumor visualization and projection of its lymphatics, both vessels and nodes, which results in a higher chance of achieving a total excision. Additionally, iatrogenic complications prove to be reduced using fluorescence during the surgical excision. The combination of fluorescence and artificial intelligence to better facilitate oncological surgery will soon become an established approach in operating rooms worldwide.
