Abdomen of a 49 year old female patient after having pelvic exenteration surgery to treat rectal cancer. Pelvic exenteration is an operation to remove most, or all, of the organs from the pelvic cavity. It is used to treat colorectal or urogenital cancers that have spread or reoccurred. This surgery was to treat mucinous adenocarcinoma of the rectal cuff, a malignant (cancerous) tumour with increased mucus secretion. The patient has also had an ileal pouch removed, resulting in an ileostomy (bag at right), and had a parastomal hernia repaired.
