Surgical weight loss is exclusively performed by laparoscopy or key hole surgery in which operations are performed through 4 – 5 small (usually 0.5 – 1.2 cm) incisions. Specialized equipment and instrumentations are necessary for this technique makes it a little more expensive than laparoscopy for other diseases. Latest additions in the field of laparoscopy include Single Incision Laparoscopic surgery, Robotic surgery & Endoluminal surgeries all of which are aimed at increasing the safety of the procedures as well as making it less invasive than conventional laparoscopic procedures.
