Jossart, of Laparoscopic Associates of San Francisco, who was not involved in the study.
Similar doubts came about when the laparoscopic surgeries first surfaced in the 1980s, he said.
The laparoscopic equipment features voice-activated lights, ceiling-mounted monitors and special green lights to reduce the strain on staff's eyes.
Because robotic surgery is faster and easier to learn than laparoscopic techniques, more surgeons can offer it, the company says.
In a separate study published this week, Dr. Paraiso and colleagues randomly assigned 53 hysterectomy patients to either laparoscopic or robotic surgery.
Supplies manufactured by Ethicon, like sutures and trocars (used for laparoscopic surgery), would become obsolete because of new product developments by the company.

The cost issue is complicated, however, because Medicare and private insurers generally reimburse hospitals the same amount for laparoscopic, robotic and open surgeries.
Today researchers are building force feedback surgical instruments for use in simulating--and eventually performing--minimally invasive surgical procedures like angioplasty or laparoscopic gall bladder removals.
Since laparoscopic gallbladder removal became the standard of care, the risk of tearing the bile duct which was the most common serious complication, has plummeted.
About 25% of the women who had laparoscopic hysterectomies stayed in the hospital longer than two days, compared with 20% of those who had robotic procedures.
In other cases, ectopic pregnancy is treated with laparoscopic surgery.
These days, surgeons will typically do a laparoscopic appendectomy.
In a January study, Finnish researchers found nearly half of 48 patients who had a Nissen laparoscopic procedure, as the traditional surgery is called, were experiencing bloating and flatulence 15 years later.
There are two main approaches to repairing a hernia: an open repair that requires a large incision, or a minimally invasive laparoscopic technique, which uses a camera to guide instruments through a tiny incision.
It's still cheap at 15 times expected 2010 earnings, he says, but management has done an excellent job of investing in products with strong recurring revenue such as surgical stapling machines and single-use laparoscopic tools.
You had to consider the risks of doing nothing or having a fairly aggressive surgery like gastric bypass -- or doing something a little less aggressive like the Lap-Band, also called the adjustable laparoscopic banding system.
Then, on the following day, the doctors were asked to perform a series of simulated operations via a virtual reality program used to train doctors in laparoscopic surgery, a form of minimally invasive surgery performed with tiny incisions and a fiber-optic camera.
The death rate was 2.1 percent with the open Roux-en-Y and 0.2 percent with the laparoscopic version. (Some patients who underwent the open Roux-en-Y had health factors that put them at greater risk for complications.) There were no deaths associated with laparoscopic adjustable gastric banding.
