Robotic resection of huge presacral tumors: case series and comparison with an open resection.

Study Design: Clinical case series and analysis.

Objective: The purpose of the present study is to evaluate the advantages and disadvantages of robotic presacral tumor resection compared with conventional open approach.

Summary Of Background Data: Conventional open approach for huge presacral tumors in the retroperitoneal space often demands excessive hospitalization and poor cosmesis.

Posterior interspinous fusion device for one-level fusion in degenerative lumbar spine disease : comparison with pedicle screw fixation - preliminary report of at least one year follow up.

Objective: Transpedicular screw fixation has some disadvantages such as postoperative back pain through wide muscle dissection, long operative time, and cephalad adjacent segmental degeneration (ASD). The purposes of this study are investigation and comparison of radiological and clinical results between interspinous fusion device (IFD) and pedicle screw.

Methods: From Jan.

Robot-assisted resection of paraspinal Schwannoma.

Resection of retroperitoneal tumors is usually performed using the anterior retroperitoneal approach. Our report presents an innovative method utilizing a robotic surgical system. A 50-yr-old male patient visited our hospital due to a known paravertebral mass.

Clinical management and outcome of 36 invasive prolactinomas treated with dopamine agonist.

Treatment of invasive prolactinoma, which has several characteristics including invasive growth into cavernous sinuses and formation of giant adenomas compressing adjacent neural structures, resulting in neurological dysfunction, has been very challenging. There are relatively few reports available describing long-term treatment outcome. Herein, we document the results of bromocriptine administration as initial treatment during average 44 months follow-up (up to 12 years) period.

Robot-assisted anterior lumbar interbody fusion in a Swine model in vivo test of the da vinci surgical-assisted spinal surgery system.

Study Design: the use of the da Vinci Surgical System to perform an anterior lumbar interbody fusion in a swine model to identify the technical properties, processes, merits, demerits, and limitations of a video-assisted robotic surgical system.

Objective: this study was designed to demonstrate the feasibility of using a robotic surgical system to perform spinal surgery.

Summary Of Background Data: video-assisted laparoscopic anterior fusion was first reported in 1995 and afterward was spotlighted for several years.

Pediatric cervical chordoma: report of two cases and a review of the current literature.

Introduction: The majority of chordomas occur between the fifth and seventh decades of life and are thus extremely rare in children, which account for less than 5% of all spinal chordoma cases.

Case Report: We report on the development of this rare condition in two boys aged 7 and 10 years. One patient presented with a palpable neck mass and dysphagia, while the other presented with posterior neck pain.

Robot-assisted anterior lumbar interbody fusion (ALIF) using retroperitoneal approach.

Background: Over the past few years, robot-assisted surgery has become increasingly popular, affecting virtually all surgical fields. It has been proven to overcome pitfalls of laparoscopic procedures, such as high complication rates and steep learning curve. We have, therefore, performed experimental anterior lumbar interbody fusion (ALIF) using retroperitoneal approach in swine model to test the feasibility of robot-assisted surgery in spinal surgery.
