Laparoscopic Gastric Bypass
In Gastric Bypass procedure, a small stomach pouch is created to restrict food intake. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine). This bypass reduces the absorption of nutrients and thereby reduces the calorie intake.
Laparoscopy is commonly performed procedure to Investigate and some key hole surgeries on abdominal and pelvic organs.
Laparoscopy is direct visualization of the abdominal cavity and intra-abdominal organs by using a laparoscopy. The laparoscope is a long thin instrument with a light source at its tip, to light up the inside of the abdomen or pelvis. Fibreoptic fibres carry images from a lens, also at the tip of the instrument, to a video monitor, which the surgeon and other theatre staff can view in real time.
Carbon dioxide (CO2) is put into the abdomen through a special needle that is inserted just above the navel. This gas helps to separate the organs inside the abdominal cavity, making it easier for the physician to see the the intra-abdominal organs during laparoscopy. The gas is removed at the end of the procedure.
LAPAROSCOPIC SLEEVE GASTRECTOMY
Sleeve Gastrectomy (Tube Gastrectomy) procedure involves removing the lateral 2/3rds of the stomach with a stapling device. It can be done laparoscopically ( keyhole surgery) but is not reversible. It basically leaves a stomach tube instead of a stomach sack.
LAPAROSCOPIC ADJUSTABLE GASTRIC BANDING
In Adjustable gastric banding procedure, a hollow band made of special material is placed around the stomach near its upper end, creating a small pouch and a narrow passage into the larger remainder of the stomach. The band is then inflated with a salt solution. It can be tightened or loosened over time to change the size of the passage by increasing or decreasing the amount of salt solution.
