Sleeve Gastrectomy – St. David’s Bariatric Center


– [Narrator] The sleeve gastrectomy is a restrictive procedure which limits the amount
of food you can eat by reducing the size of your stomach. To gain access to the abdominal cavity, small incisions are
created on the abdomen. Trocars, which serve as passageways for the surgical instruments
are placed into the incisions. Surgical instruments are
passed through the trocars to access the abdominal cavity. The surgeon examines the abdomen using a laparoscope or video camera. The average human stomach can expand to hold around one to 1.5 liters of food. While in the stomach, food is combined with digestive enzymes to help break down the food
into a more simple form so that it can be more
easily digested and absorbed once in the small bowel. During a sleeve gastrectomy,
a thin vertical sleeve is created by using a stapling device. This sleeve will typically
hold between 50-150 milliliters or is about the size of a banana. The excised portion of
the stomach is removed. The newly created gastric sleeve is able to hold approximately 1/10th of what the stomach was
able to hold before. This smaller stomach sleeve
restricts the amount of food you can eat before feeling full. The bile and pancreatic fluids
from the liver and pancreas mix with the food and allow it to be completely digested
and absorbed in the bowel. There is no rerouting of the small bowel or postoperative adjustments necessary for the sleeve gastrectomy. As with all weight loss procedures, behavior modification
and dietary compliance plays a critical part in determining the long-term success of the procedure. All surgery presents risks. Weight, age, and medical history determine your specific risks.
