Transplantationand is not a standard term found in medical literature. It appears to be a concatenation of the word transplantation and the conjunction and, rather than a defined concept. This article therefore addresses transplantation in general and related topics.

Transplantation refers to a surgical procedure that replaces a diseased or failing organ or tissue with a donor organ, tissue, or cells. Types include solid organ transplantation (such as kidney, liver, heart, and lung), vascularized composite allotransplantation (for example, hands or face), and hematopoietic stem cell transplantation. Donor sources can be deceased or living, depending on the organ or tissue. Successful matching typically involves blood type compatibility and histocompatibility, including HLA matching, as well as considerations of donor-recipient size and medical status. Allocation systems aim to balance medical need with fairness and utility.

Postoperative management centers on immunosuppression to prevent rejection, alongside surveillance for rejection, infections, and drug-related side effects. Immunosuppressive regimens vary by organ and patient and require ongoing adjustment. Organ function is monitored through laboratory tests and imaging, and patients often require long-term follow-up, lifestyle modifications, and adherence to medications.

Outcomes differ by organ and context. Kidney transplants, for example, can provide substantial survival and quality-of-life benefits, though chronic rejection and other complications may occur. Ethical and policy issues include the consent process for donation, allocation fairness, and strategies to expand the donor pool while ensuring safe and equitable access.

Historically, transplantation has progressed from early experimental attempts to modern practice with advances in immunology, organ preservation, and surgical techniques, leading to improved success rates and broader applicability.
