Endoscopically Assisted En Bloc Resection of Anterior Knee Lipoma

Abstract

Open resection of a large lipoma requires a large incision that may result in disfigurement from the scar. Endoscopic resection of the lipoma can have better cosmetic results. However, piecemeal removal of the lipoma has the disadvantage of fragmentation of the tumor before it can be determined whether it is benign or malignant. In this Technical Note, the technical details of endoscopically assisted en bloc resection of an anterior knee lipoma are described. This can provide a whole-block specimen for histologic examination.

Endoscopic En-Bloc Resection of Intra-Muscular Lipoma of the Flexor Digitorum Profundus: A Uniportal Technique

“… 13 , 14 Techniques of endoscopic lipoma resection have been proposed to improve the cosmetic result, while allowing the tumor to be resected under endoscopic visualization and adequate hemostasis. 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 In most of these techniques, lipomas are resected in piecemeal, and the tumor is fragmented before it can be determined whether it is benign or malignant. 13 , 14 , 15 , 18 , 21 Endoscopic en-bloc tumor resection has been advocated to obtain a whole block specimen for histological examination.…”

“… 5 Techniques of endoscopic lipoma resection have been proposed to solve these problems. 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 In most of these techniques, lipomas are resected in piecemeal and the tumor is fragmented before it can be determined whether it is benign or malignant. 4 , 5 , 6 , 9 , 12 Endoscopic en-bloc tumor resection has been advocated to obtain a whole block specimen for histologic examination.…”
