Surgeons perform first robot-assisted procedures in weight loss, colon and gastric fields

30.11.2006
UT Southwestern Medical Center surgeons are the first in North Texas to perform robotically assisted laparoscopic gastric-bypass and colon-resections surgeries.

The procedures were performed using DaVinci, a four-armed robot controlled by the surgeon via a joystick. DaVinci can provide better camera views and more precise surgical manipulations than are available in traditional laparoscopic surgeries.

The robot can offer easier access to some of the more inaccessible places in the body such as abdominal and gastrointestinal areas. As a result, laparoscopic surgeons expect the robotic procedures to grow in popularity for colon, gastric and esophageal operations, said Dr. Edward Livingston, chairman of GI/endocrine surgery.

Surgeries for colon cancers are on the rise, while gastric bypass procedures also are becoming more common.

Colorectal cancer is the third most common cancer in America with more than 106,000 new cases in 2006. Gastric bypass has become more popular as obesity among the nation’s population increases. More than 140,000 gastric bypass procedures are performed annually in the United States.

Laparoscopic surgeries, also called minimally invasive surgeries, are performed via several tiny holes rather than one long incision. This usually results in fewer complications, shorter recovery times and less post-operative pain.

In addition, UT Southwestern was part of a landmark study that proved laparoscopic surgery for colon cancer is just as effective as traditional open surgery.

The robot-assisted surgeries have all those patient-centered advantages, plus the robot often can provide better visuals, access and mechanical stamina, which makes an operation less-tiring for the surgeons, said Dr. Livingston.

“For particular operations, the robot has an advantage,” Dr. Livingston said. “It’s a combination of access, depth perception and magnification that provides the advantage in some cases.”

The DaVinci camera offers high-definition imaging so surgeons can see depth measurements not possible with the conventional laparoscopic cameras. And maneuvering the joystick controls on the robot is often easier than the more complex manipulations required by laparoscopic instruments.

Dr. Homero Rivas, assistant professor of GI/endocrine surgery, performed the two new procedures through the Southwestern Center for Minimally Invasive Surgery, which has premiered many of the area’s firsts in laparoscopic procedures and research.

The Southwestern Center for Minimally Invasive Surgery is one of only seven facilities in North America, and the only one in Texas, to be accredited by the American College of Surgeons for its $2 million training lab. It also has been named a Bariatric Surgery Center of Excellence by the American Society for Bariatric Surgery.

UT Southwestern surgeons previously performed Texas’ first laparoscopic bypass procedure and Dallas’ first lap band operation.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
