Fecal Bacteriotherapy

Fecal bacteriotherapy, also known as fecal transplant or fecal transfusion, is a medical treatment for ulcerative colitis, Crohn's disease, C. difficile, or lesser infections of the large or small intestine that are recurrent and unresponsive to antibiotics. Treatment involves restoration of colon equilibrium by transplanting bacterial flora from the feces of a healthy donor into a sick person's bowel through an enema. The healthy bacteria acts as an antibiotic to fight off bacteria that cause disease.

The best choice of donor is a close relative who has been tested for a wide array of bacterial and parasitic agents. Enemas are prepared and administered in a hospital environment. Typically, therapy involves a 5 to 10-day course of treatment, but many patients recover with fewer treatments.

Fecal Occult Blood Test

a fecal occult blood test checks for hidden (occult) blood in the stool. It involves placing a very small amount of stool on a special card, which is then tested in the physician's office or sent to a laboratory.

Fine Needle Aspiration

a type of biopsy, fine needle aspiration is a procedure used to extract tissue from masses or cysts for examination. With ultrasound guidance, the physician places a very fine, hollow needle into the cyst and removes a small sample of fluid from the cyst. This sample is analyzed to determine the nature of the cyst, and whether surgery is necessary to remove it. In the case of some cysts, endoscopic ultrasound (EUS) is used to inject the cyst to cause them to regress.

In other cases, such as to help diagnose pancreatic cancer, EUS is used to place stents (slender tubes) into the pancreatic duct or from the duodenum into the bile duct for drainage. In the case of individuals at high risk for cancer, EUS can help screen them for abnormalities, and help determine whether additional tests are needed. If a patient is diagnosed with pancreatic cancer, EUS can help determine whether the cancer is operable or not. If the cancer is not operable, it helps patients avoid unnecessary surgery.


During a fistulotomy, the physician surgically opens the fistula, flushes out its contents, and stitches it open or leaves it as is to heal. Part of the surgery usually requires cutting a small section of anal control muscles. Depending on the location of the fistula, there is some risk of developing minor fecal incontinence, however skilled surgery will minimize damage to this area.


This laparoscopic surgical procedure is performed under general anesthesia to treat the reflux of stomach contents into the esophagus (gastroesophageal reflux disease - GERD). Making a small abdominal incision, the surgeon removes part of the esophagus and the remaining section is attached to the stomach.
