Robotic surgery for young heart patients shortens hospital stay and speeds recovery, study indicates

28.01.2004


Operation time somewhat longer, but benefits seen



In the first-ever direct comparison of robot-assisted and traditional surgery for children’s heart defects, University of Michigan surgeons report that the robot’s help reduces patients’ recuperation time and surgery-related trauma and scarring, while extending the length of the operation by just over half an hour.

Their finding suggests that the minimally invasive surgical techniques made possible by the surgeon-controlled, camera-guided robot system can give the same surgical result as open-chest techniques, with less impact on the young patient’s body.


And although the study group was small, the finding demonstrates that robot-assisted surgery may be a good option for certain defects.

U-M Congenital Heart Center pediatric heart surgeons will present their results here on Jan. 28 at the annual meeting of the Society of Thoracic Surgeons, as part of a workshop for other surgeons on robot-assisted options for young heart patients.

Says surgeon Richard Ohye, M.D., "Robot-assisted surgery has already shown quite a bit of promise in the adult population, including adults who have congenital heart anomalies. But we feel from our experience that it can be used on many pediatric patients weighing more than 10 kilograms, and can reduce hospital stays, operative trauma, cosmetic impact and overall recovery time. And we found it does so with an acceptable impact on a patient’s time in the OR."

Despite the added expense of operating room time and the robot itself, Ohye feels that the machine will more than offset its costs over time by reducing the time a child spends in the hospital after surgery, the complications he or she will face during recovery, and his or her parents’ time away from work.

Ohye and U-M pediatric cardiac surgery colleagues Edward Bove, M.D. and Eric Devaney, M.D. performed the robot-assisted and open surgeries compared in the report. Ohye and Devaney began using the robot at the U-M’s C.S. Mott Children’s Hospital in November 2002, one year after the U-M Health System acquired the $1 million da Vinci robot system.

The surgeons use the robot for a small minority of the more than 900 surgical procedures they perform each year on U-M Congenital Heart Center patients, but they expect the number will grow in the future.

The system has two main components: a seven-foot-high robot with three cable-driven that hold tiny instruments and a small camera while they are inserted into the patient’s chest through small incisions, and a visualization and guidance station where the surgeon can manipulate the robot arms using three-dimensional images from the camera inside the patient.

The Congenital Heart Center surgeons share the robot with numerous other adult and pediatric surgeons at UMHS, from urologists who use it to remove prostate glands without damaging nearby nerves, to gynecologists who extract fibroids while sparing a woman’s uterus.

At the STS meeting, Ohye will show video footage of operations to divide a vascular ring -- a rare birth defect in which blood vessels surround the esophagus and trachea, reducing a child’s ability to breathe.

He will also present data on five vascular ring division patients who had a robot-assisted minimally invasive operation, and ten who had conventional open-chest surgery for the same problem. The data also include two other children who had robot-assisted surgery for other congenital heart defects -- a persistent left superior vena cava, and the placement of electrical leads for an implanted pacemaker to correct a heart rhythm irregularity.

The robot-assisted children ranged in age from 1 to 10 years, and the smallest weighed 10 kilograms, since the camera is too large to fit between the ribs of a smaller child.

The seven robot-assisted children had a median hospital stay of two days, compared with four days for children who had open-chest surgery. One patient in each group experienced a complication called a chylothorax, in which a lymphatic duct was punctured and leaked fluid into the chest cavity.

The children who had robot-assisted surgery were in the operating room for a median of 116 minutes, compared with a median of 83 minutes for the open-chest procedures. This difference was statistically significant. But Ohye feels it is not unreasonable, especially given the other positive effects of using the robot.

The U-M team is now offering robot-assisted surgery as an option to the parents of patients with vascular rings and certain other conditions, even as they plan to expand the range of procedures they perform with it.

Someday, they hope that real-time, three-dimensional images of the inside of the heart made by sound wave echos or electromagnetic devices rather than cameras will allow them to perform minimally invasive versions of procedures that involve entering the heart itself. Right now, the imaging techniques are used to aid open-chest procedures.

"In five or so years, perhaps we’ll perform most of the basic procedures with the robot’s help," Ohye predicts. "But for now, we’re starting with building the case for its safety and its cost-effectiveness, in certain types of cases. And we’re finding that parents of our patients are embracing it, and in some cases even asking for it."


The Michigan Congenital Heart Center is one of the world’s top centers for the diagnosis and treatment of heart and vascular disorders that arise during fetal development or childhood. Patients are often followed from before birth through adulthood. The MCHC takes a multidisciplinary team approach to patient care, and offers support services to help families cope. More than 900 surgical procedures, 600 heart catheterizations, and thousands of clinic visits take place at the MCHC each year. About half of the MCHC’s patients are from within Michigan, but families travel to Ann Arbor from around the country and throughout the world for treatment and surgery.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
