Protecting Blue Planet Trust--A Robotically Assisted Liver Donation Case
Thursday, November 30, 2017
One mutual theme of the I have got noted alongside regard to the Blackman case:
[These are] cases inward which an ambitious surgeon alongside a novel technique or using novel equipment takes on a illustration without providing total disclosure to the patient or menage unit of measurement almost the potential for increased run a peril compared to proven methods. Some hospitals are complicit inward promoting such "experiments" past times non requiring IRB blessing (i.e., human subjects review) or blessing past times to a greater extent than or less peer ethics committee. They (surgeon too hospital) create this for concern reasons, to offering themselves inward a competitive marketplace equally having "the latest too the best." The surgeon thus writes an article proclaiming the success of the novel procedure, precisely that article seldom or always looks at the long-term consequences, too it never indicates why--in damage of run a peril to the patient--the novel physical care for went forth inward the kickoff place.
Today, I summarize to a greater extent than or less other illustration that, to me, raises similar concerns. I offering it thus that you lot tin brand your ain judgment, too I welcome your comments below.
The surgery occurred several years ago. Of course, I have got no access to the detailed patient records. I alone have got materials that are inward the populace domain, precisely they offering a even out worth telling.
There is perhaps no physical care for to a greater extent than compelling than a living related liver donation, too I count the surgeons who behave out these procedures equally zero curt of heroic. USCF notes:
In living donor liver transplantation, a slice of liver is removed from a living donor too transplanted into a recipient. The procedure, performed after the diseased liver has been removed, is possible because the liver regenerates or grows. The liver's unique powerfulness to regenerate itself — combined alongside technological advances — allows to a greater extent than people to endure donors.
Regeneration happens over a curt period, perhaps days to weeks too sure as shooting inside viii weeks. When surgeons take away a slice of the donor's liver, the operate that remains grows dorsum speedily to its master copy size.
That unproblematic description belies the complexity too risks of this procedure, non alone for the recipient, precisely also for the donor. Back inward 2010, Dr. William F. Balistreri, Medical Director, Liver Transplantation Program, Cincinnati Children's Hospital Medical Center, noted (cites omitted):
Live donor liver transplantation, specifically, performance of a major hepatectomy on a good for you lot private who has no medical indication other than offering an allograft liver for the recipient, has long been viewed alongside caution too skepticism. Therefore, substantial efforts are expended to ensure the security too long-term good existence of the donor. The best outcomes for both donors too recipients have got been maximized via technical refinements, innovative pre- too postoperative management strategies, too careful follow-up.
The estimated run a peril of mortality is 0.5 to 1%. Overall donor morbidity is high, estimated to endure roughly 35%. This is usually related to the surgical incision too the possibility of blood clots; other reported problems include bleeding, infection, bile leaks, harm to the bile tree, or risks from anesthesia. Donors have got reported chronic problems, including bile strictures, reoperations, too chronic pain.
In summary, the run a peril of dying from living liver donor surgery may endure equally high equally 0.5% when donating the correct lobe. If all complications are included, 1 of every 3 donors volition sense a complication; most are considered kid or have got no permanent sequelae. Thus, centers must carefully weigh the risks against the benefits. Likewise, potential living liver donors should residuum the conclusion to donate alongside the advice of family, friends, an independent donor advocate, too the medical/surgical team. As stated past times Marsh too colleagues, "no thing how carefully correct lobar living donor transplantation is applied, the historical verdict on the ethics of this physical care for may endure harsh."
Dr. Balisteri's remarks relate to the full general case. Adding the work of robotic surgery techniques increases that risk, equally noted inward the textbook Transplantation of the Liver, past times Ronald W. Busuttil, Goran B. Klintmalm (page 734):
So, at 1 time let's become dorsum to 2008. What to a greater extent than compelling even out tin nosotros imagine than a blood brother donating a percentage of his liver to his sibling? Titled "True Example of Brotherly Love," Channel xiii reported:
Finding the perfect correspond way accepting that the correct someone may never come upwards along. But for 1 Rockford expanse menage unit of measurement the correct donor is non alone a perfect match, precisely a will of brotherly love. The ii underwent a kickoff inward the medical world. It's called the da Vinci Robotic Surgical System too at 1 time the University of Illinois Medical Center inward Chicago completed the world's kickoff minimally invasive liver resection.
This is basically bonding ii brothers inward a really unique way. Gary Tongue needed a living donor. Gary tells xiii News, "One twenty-four hr menstruation he showed upwards too wanted to know almost the alive donor transplant thing." "He" is Charles Tongue, Gary Tongue's half-brother. Gary had liver cancer which to him was a expiry judgement until both families started exploring. Charles says, "You have got to endure pretty much a perfect match. Weight, height, everything has to endure almost right."
With the most of import correspond existence blood-type. Dr. Enrico Benedetti completed the physical care for past times taking 60% of Charles' liver to supersede the diseased liver inward Gary. Doctors ended upwards finding v tumors proverb it was worse thus they thought. Gary states, "It was crude oil for awhile. It's 1 heck of a surgery to become through, precisely I recollect it's all going to worth it." Both came abode concluding calendar week too travel along to recover together. Charles states, "It's a large weight off his shoulders that you lot know he's got it too things are working goodness too I know he's going to alive now."
Gary continues on past times proverb "You actually have got to honey someone to create what he did. By giving me a slice of that. It saved my life is what he did."
The publicity continued on a liver failure back upwards grouping site, alongside the next headlines:
Surgeons used the Da Vinci System to perform the kickoff always robotic liver transplant, done at the UIC Medical Center.
Team performs world's kickoff robotic liver transplant
The even out continues (emphasis non added):
Gary Tongue, a Rockford expanse man, was the kickoff to have this transplantation performed past times robotic surgical techniques. Charles Tongue, his half-brother, was the donor of the liver. When Charles realized how high his half-brother's risks were, Gary decided he could donate a percentage of his liver to him too potentially salve his life.
UIC's main of full general surgery, Dr. Pier Cristoforo Giulianotti too his colleague Dr. Fabio Sbrana, used the da Vinci Robotic Surgical System to take away lx pct of Charles Tongue's liver. Surgeons thus placed Charles' liver into his half-brother, Gary. The physical care for would have got included a long incision roofing the entire upper abdomen that is required to take away the correct lobe of the liver. UIC's surgical team, aided past times the da Vinci Robotic System, used a unlike approach. They completed the physical care for through 4 modest incisions. They thus removed the lobe through a three-inch incision inward the lower abdomen to minimize whatsoever postoperative hurting that patients powerfulness experience.
According to Giulianotti, "this transplant could endure a turning dot lawsuit heralding a novel era inward living-donor liver transplantation. The possibility of offering the donor a perfect minimally-invasive operation, increasing the accuracy of the resection piece minimizing operative run a peril too blood loss, is a major footstep forward."
Benedetti farther explained transplantations past times clarifying the risks involved. "We beak over openly the run a peril of the donor physical care for alongside prospective donors too nosotros routinely involve an ethical commission representative to ensure that the potential donor has fully understood the risks," said Benedetti. "We quote a run a peril of mortality of 0.2-0.5 percent, according to the electrical current Literature data. We also quote a run a peril of almost xxx pct of complications, including potential for bleeding, leak of bile, infection etc. Usually after resection the liver volition regenerate to total size inside v to 7 weeks."
"Living donor liver transplantation is a life-saving option, specially for a patient alongside liver cancer," Benedetti said, "but it's really of import that the donor understands the risks too endure good for you lot plenty to endure a goodness candidate." He pointed out that inward lodge to create this surgery doctors must operate on a good for you lot human to take away much of his liver. In the Tongues' case, Charles didn't hesitate to offering his liver to his half-brother, Gary. "I couldn't inquire Charles to create this, precisely he insisted," said Gary.
The same even out showed upwards on this investor website.
In 2011, the illustration was summarized past times the surgeons too others inward an article inward Transplant International. Of relevance to us here, the article stated:
The possibility of using minimally invasive robotic technique for RLDH was discussed during the physical care for of informed consent. All technical aspects too security issues were explained, emphasizing the fact that the robotic approach had never been used earlier for RLDH. Subsequently, the ethics commission of the infirmary evaluated the donor inward accordance alongside the previously published touchstone protocol [6]. The donor agreed to proceed alongside the planned RLDH using robotic technique.
The "previously published touchstone protocol" is dated 2005. Its focus is on the full general ethical standards that apply to liver transplants, good earlier whatsoever application of robotic surgery to this sort of procedure. And nosotros are left alongside no information equally to how the surgeon explained the run a peril of the robotic technique to the patient, or how the surgeon explained why work of the robotic technique would endure superior to touchstone procedures.
Of particular note, the authors acknoweldge that "the length of surgery was longer than that commonly required for opened upwards correct donor hepatectomy," precisely thus state that "it must endure considered that the complicated venous anatomy prolonged the total operating time."
I can't evaluate the latter clause, precisely my agreement from experts inward the land is that the 8-hour duration of this illustration was considerably longer than a touchstone opened upwards donor hepatectomy, which is usually 5 to vi hours.
Years later, the Apr 2015 Annals of Surgery "Recommendations for Laparoscopic Liver Resection" (Volume 261, Number 4, at page 623) notes that the character of evidence--which presumably includes the inward a higher house article--that the outcomes of robotic liver resections "are superior or non inferior to other techniques" is "low" too that the physical care for should yet endure considered inward the phase of development that requires institutional ethical blessing too detailed reporting of results too maintenance of a registry:
It is difficult to become dorsum to 2008 too imagine what was inward the hear of the surgical squad for this case. The number is complicated past times the intense wishing of this infirmary to endure known equally a middle for robotically assisted surgery too the surgical team's financial relationships alongside the company.)

It is difficult to become dorsum to 2008 too imagine what was inward the hear of the surgical squad for this case. The number is complicated past times the intense wishing of this infirmary to endure known equally a middle for robotically assisted surgery too the surgical team's financial relationships alongside the company.)
In my mind, the squad should have got been required to instruct IRB approval (a touchstone for objective review of human subjects experiments) for this case. It was a novel applied scientific discipline existence applied to a alive donor who had piddling to hit too good documented risks of morbidity too mortality. Approval of the park ethics commission for alive donors was probable inadequate when adding on the unknown run a peril of robotic surgery. The biggest run a peril of doing these cases inward a minimally invasive way is that if you lot instruct into serious (and oft sudden) massive haemorrhage you lot won't endure able to opened upwards too command the haemorrhage speedily enough. The patient could popular off or have got severe hemorrhage earlier it is controlled. There is also the additional run a peril of a longer fourth dimension nether anaesthesia. An IRB review past times uninvolved individuals alongside a diverseness of backgrounds would have got balanced those potential risks against the additional scientific too clinical noesis that could termination from the experiment.
In summary, novel surgical approaches similar this--where in that location volition non probable endure randomized trials precisely where the run a peril is high--suggest that IRB blessing should endure operate of the evolution of the novel technology. Absent that, the patient is held hostage to the possibility that the surgeon's personal judgment--no thing how good intentioned--might endure colored past times commercial strategies of that doctor, the hospital, too the equipment supplier.
