Abstract
Laparoscopic gastric pacing (LGP) is a minimally invasive technique that is performed for the treatment of obesity. LGP was first developed in the early 1990s for gastroparesis, and was also found to be effective in the treatment of obesity. The application of electrical current to the stomach alters gastric myoelectrical activity, without any changes in the gastrointestinal anatomy. The exact mechanism of LGP remains to be elucidated. However, potential mechanisms to assess the success of LGP might include an increased feeling of satiety as the result of reduced gastric emptying, or changes in neuropeptide levels.
LGP is a minimally invasive technique that is potentially safe and effective for treating obesity; nevertheless, the selection of patients for gastric stimulation therapy appears to be an important determinant of the outcome of this treatment.
This article reviews the current status, potential mechanisms of action, operating techniques, complications, postoperative management and outcomes, and possible future applications of gastric stimulation in obesity management.

The lead of the pacemaker is inserted into the muscle tunnel of the stomach which positions are on the lesser curvature. An adequate length of the tunnel is mandatory, to ensure that both of the electrodes are buried within the tunnel wall. The location of the generator should be on the anterior abdominal wall. The device that controls the settings (wand) is covered with a sterile cover and the system impedance is checked. (MP4 16338 kb)
