A "double organ" can refer to several different concepts depending on the context. There isn't one single definition. Let's explore the different meanings:
1. Simultaneous Transplantation of Two Organs
This is perhaps the most common understanding of a "double organ." It refers to a dual organ transplant, where a patient receives two organs simultaneously during a single surgical procedure. Examples include:
- Liver and kidney transplant: As seen in the example of four-year-old Bailey Scruggs receiving a liver and kidney transplant. (https://www.texaschildrens.org/content/dual-organ-transplant-brings-new-life-4-year-old)
- Heart and lung transplant: Frequently performed dual organ combination. (https://optn.transplant.hrsa.gov/policies-bylaws/a-closer-look/multi-organ-transplantation/)
- Kidney and pancreas transplant: Another common dual organ transplant. (https://optn.transplant.hrsa.gov/policies-bylaws/a-closer-look/multi-organ-transplantation/)
Some patients benefit from this approach, improving their chances of survival and quality of life. A patient may receive a "double organ transplant" as mentioned in the reference indicating a liver and another organ transplanted simultaneously.
2. Paired Organs
Another interpretation refers to naturally occurring paired organs. Lungs are an example. Because they come in pairs, procurement and transplantation are often considered as a single unit or as two separate organs depending on the specific circumstances. This is highlighted in the report on organ procurement organizations reporting practices: (https://oig.hhs.gov/reports/all/2013/medicare-could-have-saved-millions-if-organ-procurement-organizations-had-correctly-reported-procurement-of-double-lungs-as-two-organs/)
3. Congenital Anomalies
In some cases, individuals might be born with duplicated organs. A double uterus is an example of a congenital anomaly where a person has two uteruses. (https://www.mayoclinic.org/diseases-conditions/double-uterus/symptoms-causes/syc-20352261)
