Abstract
Angiomyolipoma of the liver (AML) is an infrequent neoplasm composed of three tissues (adipose, muscle and vessels). In spite of advances in radiology, preoperative correct diagnosis is difficult. Clasically, a conservative management strategy was adopted in patients with asymptomatic tumors less than 5 cm with undoubtful diagnosis. But after publishing some few cases of malignant angiomyolipoma a more radical has been advocated. Laparoscopic resection of liver tumors is becoming a excellent approach for operating on benign liver tumors. Usually is performed using five trocars but in some cases a less invasive technique with three trocars could be used. We present a laparoscopic resection of liver angiomyolipoma in a 65 year-old male using only three trocars and also discuss the optimal management of AML and technical tips of three-trocar technique.
Highlights
The angiomyolipoma of the liver (AML) is a very infrequent benign tumor characterized by three components: adipose, vascular, and muscular [1,2,3,4,5,6,7]
We describe here a new case concerning a laparoscopic resection with only three trocars; we have revised the literature and discussed surgical indications
The hepatic angiomyolipoma (AML) is a solitary mesenchymal tumor, not encapsulated and of a variable size (1 to 36 cm) [1, 5, 6] that is composed of three variable tissues: muscular cells, thick-wall vessels, and mature adipose tissue [1,2,3,4,5,6,7]
