Core tip: Ganglioneuromas are rare, benign neurogenic tumors. Given their often close proximity to major vessels, minimally invasive resection can be challenging. We report a case of laparoscopic resection of a retroperitoneal ganglioneuroma adhering to the portal vein and celiac axis. Laparoscopy enhanced visualization of the tumor and its relationships to surrounding vital structures. Ultrasonic energy devices and adjusting liver retraction allowed for manipulation of the mass and safe dissection in a tight space. With sufficient experience in laparoscopic surgery, careful patient selection, and preoperative imaging and diagnostics, laparoscopic ganglioneuroma resection can reduce postoperative morbidity, hospital length of stay, and recovery time for the patient.
