Inquiry into death of teenager at hospital.
Ryan Senior, of Redditch, was admitted for minor keyhole surgery on his abdomen that should have taken just 40 minutes.
But he suffered bleeding and multiple organ failure after a blood vessel was allegedly punctured during the low-risk op.
His devoted mother Sarah, a single parent, is too distraught to comment about the death of her only child who was born on Mother's Day.
A family friend said: "Sarah's broken-hearted. As mother and son they were very close. He was her only child.
The tragedy happened on February 16 after Ryan was admitted for a laparoscopy, a low-risk surgical procedure that allows a surgeon to access the inside of the abdomen and the pelvis.
It is believed Ryan was anaesthetised before a laparoscope - a small flexible tube that contains a light source and a camera - was inserted through his belly button.
His abdomen had been inflated with carbon dioxide gas to allow the laparoscope to move about. But complications occurred after a major blood vessel was allegedly ruptured.
Sources have claimed the carbon dioxide gas being used then entered Ryan's bloodstream - leading to rapid, overwhelming multiple organ failure.
Ryan is thought to have received up to 30 pints of blood over two hours, as the theatre team fought in vain to save his life.
An inquest into his death was opened and adjourned at Birmingham Coroner's Court on Februa r y 25.
Birmingham Children's Hospital has confirmed it has launched a full inquiry.
