NCP chief Sharad Pawar on Tuesday night underwent endoscopy at a hospital here a day before schedule, a family member said, adding that doctors might take a call on operating him late night itself. "The doctors performed endoscopy on Pawar. They would soon take a call on operating him. They could advance the surgery and perform it tonight itself. We are waiting for further communication," the family member said.

After Pawar (80) complained of abdominal pains on Sunday, he was taken to the hospital for a check-up on the same evening. However, he was admitted to the hospital on Tuesday evening, a day ahead of the scheduled surgery for a gall bladder issue, after he experienced pains in his abdomen, NCP leader Nawab Malik had said.
