New York, May 6: A team of neurosurgeons led by an Indian-origin professor from the University of Pennsylvania School of Medicine performed the first-ever robot-assisted spinal surgery to successfully remove a rare tumour on the patient's neck.

The robotic approach assisted with a three-part, two-day complex procedure for a rare chordoma tumour removal from a patients' neck, where the skull meets the spine.

Chordoma is a rare type of cancer that occurs in the bones of the skull base and spine. A chordoma tumour usually grows slowly and is often asymptomatic for years. 

It is extremely rare and it affects only one in a million people each year.

"This would be a first ever use of a robot in this manner -- a rare approach to an already rare and complex case," Neil Malhotra, an assistant professor of Neurosurgery and Orthopaedic Surgery said in a statement.

"Our team needed to reconstruct the removed area of patient's spine using bone and rods, and that was only the beginning," Malhotra added.

He added that due to the placement of the tumour, the removal could compromise the structural integrity of the patient's spine, causing permanent paralysis.

There was also a risk of complications such as bone and tissue breakdown, loss of sense of smell, fine motor skill issues and complete paralysis.

"If we could not remove the entire tumour, it would likely grow back, perhaps more aggressive than before," Malhotra added.

The surgery was performed in three parts and now nine months after the surgery, the patient is back to work in commercial contracting.

Thane (PTI): A court in Bhiwandi in Thane district on Saturday adjourned the hearing in the criminal defamation case filed against Congress leader Rahul Gandhi by a Rashtriya Swayamsevak Sangh (RSS) worker to December 20 due to non-availability of a crucial prosecution witness.

Advocate Narayan Iyer, counsel for Rahul Gandhi, confirmed the adjournment, stating that the witness, Ashok Saykar, currently Deputy Superintendent of Police in Barshi in Solapur, could not remain present due to personal reasons.

Saykar's evidence is now likely to be recorded on December 29.

His testimony is considered key because he, as police sub inspector in 2014, conducted the preliminary inquiry into the private defamation matter under Section 202 of the Code of Criminal Procedure (CrPC).

It was on the basis of Saykar's submitted report that the court subsequently issued process (summons) against Rahul Gandhi under Section 500 of the Indian Penal Code (IPC).

The criminal defamation case was filed by local RSS worker Rajesh Kunte following a speech given by Rahul Gandhi at an election rally near Bhiwandi on March 6, 2014.

The case stems from the Congress leader's alleged statement that "the RSS people killed (Mahatma) Gandhi."

The matter is being heard by Bhiwandi Joint Civil Judge, Junior Division, P M Kolse.

The hearing had previously been adjourned on November 15 after the complainant's counsel, Advocate Prabodh Jaywant, moved an application seeking permission to examine Saykar, who had submitted the probe report to the court.

The matter was originally scheduled for November 29 but was deferred to December 6 after Rahul Gandhi's legal team sought an adjournment citing their non-availability. The proceedings will now resume on December 20.
