Surgery for Right Upper Retroperitoneal Tumors

Abstract

It has been suggested that a lower resection rate of the right upper retroperitoneal tumors (RPTs) compared to left upper RPTs can be attributed to more frequent tumor invasion of the inferior vena cava. In our hospital, invasion of inferior vena cava in right upper RPTs is comparable to that of left upper RPTs. However, it is challenging to resect the right upper RPT due to the fact that the tumor is located close to the liver, including important structures such as the first, second, and third hepatic hila, and is adjacent to the head of pancreas, duodenum, common bile duct, and portal vein. Invasion of the above structures brings tremendous difficulties to surgical resection of RPTs located in this area.
