  • The Barnett Continent Intestinal Reservoir (BCIR) is one type of intestinal ostomy. It is a modified version of the continent (Kock pouch) ileostomy, which was pioneered by Dr. Nils Kock in the 1960’s. The major modifications when compared with a Kock pouch are a collar made from a piece of the patient’s own intestine, an isoperistaltic valve and a lateral pouch design.

    These design modifications attempt to reduce the incidence of the most serious complications of continent reservoirs-slipped valves and fistulas.

    The entire pouch, collar and valve, are formed from about 2 feet of the patient’s own intestine. When the patient experiences a sensation of fullness the pouch is drained by inserting a catheter into the buttonhole-shaped opening, or stoma, located low on the torso just above the pubic area. Drainage is usually done two to five times each day. The rest of the time, the opening is covered with a small adhesive bandage.

    Unlike a conventional ileostomy, there is no projecting spout, and no appliance. The opening or stoma is flush with the abdominal wall. This means patients can wear any type of clothing and participate in virtually all their normal activities without restriction.

  • A general surgeon, William 0. Barnett, M.D., F.A.C.S., began making these modifications to the original Kock technique in 1979 and accumulated a personal series of over 300 cases.

    In 1988, Dr. Barnett relocated to St. Petersburg, FL and joined the staff at Palms of Pasadena Hospital where he created The Continent Ostomy Center. With the assistance of Dr. James Pollack and Dr. Ernest Rehnke, further enhancements to the procedure where made to bring it to where it is today.

    As you can see, the BClR has a long history, and we are very proud to keep Dr. Barnett’s and Dr. Pollack’s legacy alive. Today, Ernest Rehnke, M.D., heads the Center’s team and the program has had patients from all over the United States.
