The surgical insertion of an adjustable gastric band is often referred to as a lap band procedure or band placement. First, a small incision (typically less than 1.25 cm or 0.5 in.) is made near the belly button .
On February 14, 2009, the UK's first SILS implantation of a gastric band was performed by the pioneering surgeon Professor Franco Favretti and his Healthier Weight team. The patient, a 50-year-old female, received a gastric band (LAP-BAND) implanted through the umbilicus. The patient made an excellent recovery and was discharged the following day.
Combined restrictive and malabsorptive techniques are called gastric bypass techniques, of which Roux-en-Y gastric bypass surgery (RGB) is the most common. In this technique, staples are used to form a pouch that is connected to the small intestine , bypassing the lower stomach, the duodenum , and the first portion of the jejunum .
The gastric bypass group had an average peak alcohol breath level of 0.08%, whereas the control group had an average peak alcohol breath level of 0.05%. It took an average of 108 minutes for the gastric bypass patients group to return to an alcohol breath of zero, while it took the control group an average of 72 minutes. [journal 15]
Diagram showing parts of the stomach. The human stomach can be divided into four sections, beginning at the cardia followed by the fundus, the body and the pylorus. [7] [8] The gastric cardia is where the contents of the esophagus empty from the gastroesophageal sphincter into the cardiac orifice, the opening into the gastric cardia.
Laparoscopy (from Ancient Greek λαπάρα (lapára) 'flank, side' and σκοπέω (skopéō) 'to see') is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera.

The gastric folds (or gastric rugae) are coiled sections of tissue that exist in the mucosal and submucosal layers of the stomach. [1] They provide elasticity by allowing the stomach to expand when a bolus enters it. These folds stretch outward through the action of mechanoreceptors, which respond to the increase in pressure. [2]
