New surgical technique for removing inoperable tumors of the abdomen

02.05.2012
Abdominal tumors involving both roots of the celiac and superior mesenteric artery (SMA) are deemed unresectable by conventional surgical methods, as removal would cause necrosis of the organs that are supplied by those blood vessels.

A case report published in the journal American Journal of Transplantation presents a novel surgical technique that enables surgeons to remove tumors that are unresectable by the usual surgical techniques.

Led by Tomoaki Kato, MD, FACS, of Columbia University, surgeons removed tumors in 3 patients involving both the celiac artery and SMA using new surgical techniques never performed before, known as "ex vivo" surgery where the organs are removed to do surgery.

First, surgeons removed entire abdominal organs together with the tumor. The patient is "organless" during this period. The tumor was cut and blood vessels were reconstructed using synthetic vascular grafts. Surgeons then re-implanted the organs back into the patient's abdomen, connecting blood vessels and gastrointestinal tracts.

Surgery was successful, and all 3 patients are alive with no tumor recurrence to date after 2 to 4 years from the surgery.

"Our technique appears both feasible and effective in the proper clinical situation when performed by a multidisciplinary team experienced in multivisceral transplantation," Kato notes. "This technique can expand the role of transplant surgery in specific oncological problem, and more patients with 'inoperable' tumors can be operated."

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
