According to the American Society for Metabolic and Bariatric Surgery, there are two basic approaches to weight loss surgery:
Restrictive procedures that decrease food intake
Malabsorptive procedures that alter digestion, causing food to be poorly digested and incompletely absorbed
Laparoscopic or Minimally Invasive Surgery Alternatives
At HackensackUMC Mountainside Hospital, we perform the following minimally invasive surgeries:
These procedures are known as laparoscopic. When a laparoscopic operation is performed, a tiny video camera and surgical instruments are inserted through small incisions made in the abdominal wall and the surgeon views the procedure on a separate high definition video monitor.
This provides the laparoscopic surgeon with better visualization and access to key anatomical structures while also eliminating the need for one long abdominal incision.
A recent study found that patients who have laparoscopic weight loss surgery experience less pain after surgery, as well as easier breathing, improved lung function and higher oxygen levels. Other benefits of laparoscopy include fewer wound complications such as infection or hernia and a quicker return to pre-surgery activity levels.
Laparoscopic procedures for weight loss employ the same principles as their "open" surgery counterparts and produce similar excess weight loss. However, not all patients are candidates for this approach and all bariatric surgeons are not trained in the advanced techniques required to perform this less invasive method. The American Society for Bariatric Surgery recommends that laparoscopic weight loss surgery should only be performed by surgeons who are experienced in both laparoscopic and open bariatric procedures.
