Bangkok Biomaterial Center: 15 Years Experience in Tissue Banking

Abstract

Tissue banking is started in Thailand in 1979 at the Department of Orthopaedic Surgery, Siriraj Hospital, Bangkok. At that time tissues produced were freeze-dried bone allografts which were sterilized by ethylene oxide. In 1984, the freeze-dried tissue allograft project received an award from the National Research Council of Thailand. The Bangkok Biomaterial Center was officially inaugurated on December 6, 1984 under the Royal Patronage of H.R.H. Princess Galyanivadhana and is located inside the Siriraj Hospital. The Center is involved in the procurement, processing, storage and development of bone and tissue allografts. A variety of allografts including bone, cartilage, fascia lata, dura mater, cornea and also cardiovascular tissues have been procured and processed. Preservation and long-term storage are accomplished by freeze drying and deep freezing. Grafts prepared by the Center are supplied free of charge at the request of surgeons in hospitals throughout Thailand and in neighboring countries. The Center acts as the National Tissue and Allograft Bank of Thailand. From December 1984 to February 2000, the Center has processed a total of 20 524 allografts: 16 981 freeze-dried bones, 705 deep-frozen bones, 1838 freeze-dried amnion, 559 freeze-dried dura mater, 342 freeze-dried fascia lata, 46 costal cartilage, 18 corneas, 2 skin, 5 trachea, 22 fresh tendon and 6 bone substitutes. The allografts processed were used in 2049 patients by 223 surgeons in 53 hospitals in Thailand and 4 cases in neighboring countries. There have been 413 cadaveric donors, 619 living donors, 16 brain dead donors and 270 graveyard donors. There have been complications in 126 patients (6.14%) due to various clinical conditions. There have been production and application of 4 hydroxyapatite occular implant by the Center. The Center is in the process of establishing a full-fledged Research, Clinical and Cell Culture Laboratory.
