Pancreas transplant surgery is performed under a general anesthetic. An incision is made in the lower abdomen and the new pancreas placed inside. The old pancreas is usually left inside the body unless there is a cause for future concerns (infection etc.). The new pancreas is then attached to the blood vessels and small intestine – enabling it to produce insulin and to work alongside the old pancreas – which will continue to drain any digestive juices. A catheter (tube) is inserted into the bladder to help drain any fluid build-up, and sometimes drainage tubes will be left in the abdomen following the procedure. The initial incision is then closed using clips or stitches. Your new pancreas should begin to work straight away. Pancreas transplant surgery is often combined with kidney transplant surgery. Sometimes there may be a shortage of donor pancreases; in this case a living relative may be able to donate a portion of their pancreas. Your surgeon will explain to you the relevant procedure to your condition.
