Giant Pelvic Neurofibroma in Patient with Plexiform Sciatic Neurofibroma and Neurofibromatosis Type 1

Clinical efficacy of robot-assisted thoracoscopic surgery for posterior mediastinal neurogenic tumors

Background

Robot-assisted thoracic surgery (RATS) has an increasing usage throughout the world. This retrospective cohort study aimed to objectively compare the surgical results between video-assisted thoracic surgery (VATS) and RATS in posterior mediastinal neurogenic tumors (PMNT).

Methods

We retrospectively reviewed the clinical data of 130 patients diagnosed with posterior mediastinal neurogenic tumor between 2015 and 2018. Magnetic resonance imaging (MRI) or enhanced computed tomography scan (CT-scan) was used to locate the tumor and investigate the Adamkiewicz’s artery preoperatively. The individual surgical approach was determined by both tumor size and patient’s willings.

Results

The surgical time in RATS (43.2±12.6 min) was tended to be less than that in VATS (47.4±11.9 min) (P=0.054). Meanwhile, the estimated blood loss in RATS group (85.8±22.6 mL) was significantly less than that in VATS group (95.3±28.4 mL) (P=0.040). However, the duration of chest tube (days) and volume of drainage (mL) had no significant difference between two groups (P=0.12 and P=0.68, respectively). The postoperative hospital stay (days) of patients in RATS group (2.2±0.4 days) was significantly shorter than that in VATS group (2.4±0.6 days) (P=0.031). There were no significant differences between two groups in the incidence of the postoperative complications and adverse reactions.

Conclusions

RATS has the superiorities in terms of surgical blood loss and postoperative hospital stay over VATS for posterior mediastinal neurogenic tumor. In conclusion, RATS could be a feasible and safe way for resecting posterior mediastinal neurogenic tumor.
