Sleeve gastrectomy is the newest
available weight loss surgery, usually performed on highly obese
or at-risk patients.
During the
procedure, more than half of the stomach is removed
laparascopically, leaving the remaining portion in the shape of
a sleeve. Sleeve gastrectomy restricts food intake, provides
weight loss; and allows for a second surgery—a gastric bypass or
duodenal switch—to be performed later.
-
The procedure may be used on its own
or with a second surgery.
-
Risk and weight loss are more moderate
compared with other surgeries.
-
Most patients will lose 30%-50% of
their excess body weight over a 6-12 month period with
sleeve gastrectomy alone.
-
May be followed by a gastric bypass or
duodenal switch, typically 6-18 months following initial
surgery.
