VERTICAL SLEEVE GASTRECTOMY<br />
Intro<br />
The Vertical Sleeve Gastrectomy (VSG) or Laparoscopic Sleeve Gastrectomy (LSG) is an emerging weight<br />
loss procedure. It involves reducing the size of the stomach only, without any intestinal bypass or artificial<br />
device.<br />
The procedure was first presented in 2002 as a “Staged Procedure” for the Super-Super morbidly obese<br />
patients (BMI >60), with the aim to decrease operative time and effectively "downstage" a high risk patient<br />
to a lower risk group. <strong>Patient</strong>s would lose 100-150 lbs and return to surgery 12-18 months later for<br />
intestinal bypass (stage II). Because there was substantial weight loss after the sleeve alone, it was<br />
eventually offered as a primary (stand alone) weight loss procedure.<br />
Anatomy after the Vertical Sleeve Gastrectomy<br />
Blood vessels along the greater curvature of the stomach are divided and a new stomach is tailored along<br />
the lesser curvature with staples that seal and cut. About 80% of stomach is removed, leaving the<br />
remaining stomach shaped like a banana. It is purely a restrictive procedure. Compared to the gastric<br />
bypass, the volume of the stomach is larger, but there is no intestinal malabsorption. Like the bypass, there<br />
may be a hormonal effect that reduces sense of hunger.<br />
Surgical Procedure and Hospital Stay<br />
Over 98% of sleeve gastrectomies are performed laparoscopically, with an average of 5 small incisions.<br />
They all require full general anesthesia and about 1 to 1 ½ hours of surgical time. Most patients stay one<br />
or possibly two nights in the hospital.<br />
