Liver Cyst
摘要
Liver cysts in the pediatric population are uncommon, and in most cases, they are simple cysts that remain asymptomatic and are managed conservatively. In selected cases, especially when cysts enlarge, cause symptoms, or show complex features on imaging, surgical intervention is indicated. Robotic resection is a rare surgical approach to liver cysts, but it offers potential advantages in precision and visualization. This chapter describes our center’s technique and experience with robotic excision of pediatric liver cysts, representing the largest published series to date on this approach. Preoperative planning is based on the imaging with USS, for an initial characterization of the cyst, MRCP, investigation of choice to delineate the anatomy, or in specific cases, HIDA scans. A three-arm da Vinci robotic system is utilized; patient positioning and port placement vary based on cyst localization and patient age. Complete excision represents the goal to achieve; therefore, for large cysts, aspiration is recommended to aid dissection. Resection begins with the external portion of the cyst, followed by careful dissection at the liver-cyst interface using monopolar or bipolar instruments based on proximity to vascular or biliary structures. Hemostatic sealants like TISSEEL or FLOSEAL are routinely applied. Among the primary benefits of robotic-assisted approach are typically rapid patient recovery, with low postoperative pain and short-term hospitalization. In conclusion, it can be stated that although no superiority over laparoscopy or open surgery has been demonstrated, robotic liver cysts resection in pediatric patients represents a minimally invasive alternative that offers clear benefits in terms of ergonomics, visibility, and operative dexterity.
