Another example:

"My wife died after surgery to remove her gall-bladder, the surgeon had severed the bile duct thinking it was the cystic duct. The attempted repair failed and due to lack of oxygen my wife died 5 weeks later, 4 of those weeks in ITU."

"The most common error made during this procedure is the cutting of the common bile duct that occurs in 1 out of every 200 procedures, injuring an average 4,000 patients pear year. Cutting of the bile duct can cause jaundice or leakage into the abdominal cavity. Permanent pain and digestive problems can occur with the patient and lead to the life threatening infection Cholangitis is left untreated."
