A 64-year-old West Virginia man is suing a Maryland doctor for allegedly stapling his rectum shut during an operation.
Ronald Watkins claims the 2004 surgery for a rectal tumour left him with permanent bowel problems.
Watkins then underwent four additional surgeries after being unable to defecate for 17 days.
The attorney for Doctor Manuel Casiano said that the bowels were merely swollen shut due to other medical problems.
The federal lawsuit is being heard in a Baltimore courtroom.
A judgment is expected before the week is out.
