Surgeons at WashU Medicine and the Barnes-Jewish Transplant Center have reported what they describe as the world's first robotic combined liver and kidney transplant, performed through a single incision of roughly three inches instead of the 16 to 20 inch opening that conventional double transplant surgery requires.
The procedure was announced on September 2, 2026, and involved Darrell Bosworth of Martinsburg, Missouri, who developed failure of both organs as a result of advanced liver disease and cirrhosis. The operations took place in May.
Patients who need both a liver and a kidney are among the most fragile people in transplant medicine, and the size of the incision is not a cosmetic detail for them. It determines how much abdominal muscle is cut, how much pain follows, and how long recovery takes in a body already depleted by months or years of organ failure.
Two Operations, One Set of Incisions
Adeel Khan, a professor of surgery at WashU Medicine, performed the transplants with Jessica Lindemann, an assistant professor of surgery. Khan carried out one of the first robotic kidney transplants in the United States in 2020 and the country's first robotic liver transplant in 2023, both at Barnes-Jewish Hospital.
Patients who need both organs at once, Khan said in the institutional announcement, are "often among the sickest and most fragile patients we care for." He described the goal as performing both transplants safely while minimizing the physical and psychological impact of surgery.
Lindemann described the planning as the harder part. "The liver transplant portion is the more complicated surgery," she said, adding that the team was deliberate about the sequence of the operations, how the robotic approach would be used, and how the whole team would work together at each step.
The liver transplant came first and lasted just over eight hours, with Khan operating from a robotic console using a highly magnified three-dimensional view while Lindemann worked at the bedside. The team removed the original liver, placed the donor liver through the main incision, and connected the key blood vessels and bile ducts through smaller secondary openings.
The following morning, with the new liver functioning well, the team returned to the operating room and completed the kidney transplant using the same incisions, in just over half the time the liver operation had taken.
Recovery Measured in Days Rather Than Weeks
Bosworth's condition before surgery illustrates why the recovery timeline matters. By May he had lost roughly 70 pounds, was largely confined to bed, required dialysis and frequent procedures to drain abdominal fluid, and was experiencing worsening episodes of confusion related to his liver disease.
A donor liver and kidney became available in late May, three weeks after he was placed on the waiting list.
Both organs began working immediately. By the tenth day after surgery his mental clarity had improved significantly and both transplanted organs were functioning well. Within two weeks he could climb a short flight of stairs, and he now moves independently with a walker. He reported unusually little pain after the operation.
Kidney failure that follows liver disease is common rather than unusual. Severe liver disease can impair blood flow to the kidneys and lead them to fail, which is why combined transplants exist as a category. WashU Medicine and Barnes-Jewish Transplant Center perform around 20 combined liver and kidney transplants a year.
A Single Case Is Not Yet a Standard of Care
This is one patient with roughly three months of follow-up, reported by the institution that performed the surgery. It has not appeared in a peer-reviewed journal, and no comparative outcome data exist.
What a single successful case establishes is feasibility in a carefully selected patient at a center with unusual depth of experience. What it does not establish is whether robotic combined transplant produces better survival, fewer complications, or lower rates of organ rejection than the open approach across a broader population.
Robotic transplantation also has real constraints. It requires a team built over years. The WashU group formed its robotic transplant program about five years before its first robotic liver transplant, starting with kidneys, and had completed more than 30 robotic kidney transplants by the time of that 2023 case. Patient selection matters too: body habitus, prior abdominal surgery, vascular anatomy, and the degree of illness all influence whether a minimally invasive approach is safe.
Khan framed the case in those terms, describing it as reflecting years of experience and team development along with an institutional commitment to advancing surgical innovation safely and rigorously. His stated hope was that over time these approaches would allow more transplant patients to benefit from less invasive surgery and an easier recovery.
That is a considerably more measured claim than a breakthrough headline suggests, and it is the accurate one.
Access, Cost, and the Centers That Offer Robotic Transplant
For patients and families, the immediate limitation is geographic and institutional rather than clinical.
Robotic abdominal organ transplantation is performed at a small number of centers. A patient listed at a typical regional program should not expect a robotic option today.
Patients who want to understand their options can ask a transplant coordinator directly whether the center performs robotic kidney or liver transplants, how many it has done, and whether their specific anatomy and illness severity would make them a candidate. Referral to another center is possible but involves relisting, travel, and insurance considerations that vary by plan.
Transplant coverage under Medicare and most commercial plans is generally tied to approved transplant centers rather than surgical technique, so the robotic approach itself is unlikely to be a separate coverage question. Travel and extended stays near a distant center are the more common financial burden, and many transplant programs have social workers who can identify housing and travel assistance.
Anyone waiting for a combined liver and kidney transplant should continue current treatment, including dialysis and fluid management, without change. Nothing in this report alters existing medical guidance, and no patient should defer a scheduled transplant in hope of a robotic option.
Larger case series and comparative studies would be the next meaningful step. Until those exist, this remains a promising demonstration rather than a new standard.
Key Questions Answered
What was performed and where? Surgeons at WashU Medicine and the Barnes-Jewish Transplant Center in St. Louis performed what they describe as the world's first reported robotic combined liver and kidney transplant. The operations took place in May 2026 and were announced on September 2, 2026.
How is this different from a standard combined transplant? Conventional open surgery for a combined liver and kidney transplant typically requires a 16 to 20 inch incision that cuts through most of the abdominal muscles. The robotic approach used a single incision of roughly three inches plus smaller secondary openings.
How is the patient doing? Both organs functioned immediately. By the tenth day after surgery his mental clarity had improved and both organs were working well. Within two weeks he could climb a short flight of stairs, and he now moves independently with a walker.
Does this mean robotic transplant is now available everywhere? No. Robotic abdominal organ transplantation is performed at a limited number of centers, and availability depends on individual patient anatomy and illness severity. Building such a program takes years of team development.
Has this been published in a medical journal? Not as of this report. The information comes from the institution that performed the surgery. No peer-reviewed publication or comparative outcome data have been released.
Who needs a combined liver and kidney transplant? People whose severe liver disease has also caused kidney failure. Advanced liver disease can impair blood flow to the kidneys and lead them to fail, which is why the two organs are sometimes transplanted together.
Should a patient on a transplant waiting list change anything based on this? No. Current medical guidance is unchanged. Patients should continue their existing treatment and discuss any questions about surgical approach with their transplant team rather than deferring a scheduled procedure.
