Deerju Mistry, 60, had been suffering from intestinal bleeding and doctors at the Rajendra Institute of Medical Sciences (RIMS) cut his abdomen for a surgery.
He died Thursday after no doctors attended to him for more than 12 hours after that, the reports said.
RIMS director N.N. Agrawal said: "A probe has been ordered into the incident. Anyone found guilty will not be spared.
"After cutting open the patient's stomach, the junior doctors waited for the senior surgeon to arrive but he didn't turn up. The patient bled to death after sometime," Agrawal added.
