Surgeons at the University of Pennsylvania Medical Center, Pittsburgh, USA, have reported on the outcome of laparoscopic surgery on 275 patients.
The report gives details of follow-up of patients for up to 31 months.
During the laparoscopic procedure the surgeons made up to five small incisions to access the abdominal cavity. Traditionally the procedure has been performed by open surgery.
Laparoscopic gastric bypass on 275 obese patients - 83% loss of excess weight at 2y.
The study showed that two years after surgery patients had lost on average 83 per cent of their excess weight.
95 per cent of patients reported significant improvements in quality of life. One died from a pulmonary embolus.
27 per cent of patients suffered minor complications while 3.3 per cent suffered major problems.
Surgeon Dr Philip Schauer said: "Since there are nearly 8 million people in the USA suffering from severe obesity and only surgery has any proven long-term benefit, a minimally invasive approach to gastric bypass offers many patients, who would otherwise shun surgery, a chance to reconsider surgery as a permanent solution to this devastating disease of obesity.
"The important outcomes relating to the goal of open bariatric surgery (such as weight loss and improvement of comorbidities and quality of life) appear to be equally favorable for minimally invasive gastric bypass. Long term follow-up, however, will be necessary to confirm that the laparoscopic approach is equally enduring."
