It is a type of bariatric (digestive) surgery that is designed to restrict the capacity of the gastrointestinal system to consume and hold food. The procedure may also be called as sleeve gastrectomy or tubal gastrectomy.
To really get a visual it is best to watch and animated gastric sleeve video. This type of procedure works by reducing the size of the stomach by about 70% to 80% from the normal. The surgical team achieves this by cutting the greater curve of the stomach, removing it and stitching together the parts that are left. The remaining parts appear to be cylindrical in shape or they look like a sleeve, hence the name of the procedure. The greater curve of the stomach contains glands that produce hunger-stimulating hormones. So in theory, removing this part decreases one’s hunger pangs and urges. The outlet part is untouched so the stomach retains a majority of its functions and physiology.
Gastric sleeve surgery may be done via two methods – the open method or the laparoscopic or keyhole method. The open method involves opening the abdominal cavity. This poses risk for infection and it involves a longer period for recovery. However, this route gives the surgical team great visualization, thus reducing the appearance of common complications post-surgery. This is also used for extremely obese patients.
The laparoscopic method is definitely the more preferred between the two because it involves a quicker recovery period and a shorter stay in the hospital. If you ever have a choice in any surgery it is always best to go with laparoscopic.This is difficult to do because the abdominal cavity stays closed and visualization is only achieved though a video probe, which is introduced to the body via a small incision. If the patient is not severely obese and he/she wants to go back to work immediately, he/she can opt to undergo this type of gastric sleeve surgery.
In both methods, sutures and staples need to be applied to seal fully the incised area. This is a high risk procedure and strict aseptic techniques must be employed to prevent the introduction of pathogens inside the body cavities.
