Most bariatric procedures are performed as laparoscopic—or
robotically minimally invasive—procedures, through tiny incisions.
With laparoscopic surgery, patients benefit from less pain, fewer
complications and a shorter hospital stay. The selection of each
procedure is individualized to meet the patient’s needs and is made
jointly by the surgeon and the patient.
The laparoscopic gastric bypass has
become the “gold standard” of all
bariatric operations to which other
procedures are compared. This procedure
results in weight loss by two different
mechanisms. The first part of the
procedure is to create a very small
“new” stomach (about 15 ml or ½ oz) and
separate it from the old stomach
(restriction). Next, the remaining
stomach and a portion of the intestines
are bypassed so food will not be
absorbed by these sections of the GI
tract (malabsorption). The new tiny
stomach pouch creates the sensation of
becoming satiated with a very small
portion of food. The bypassed intestine
reduces the amount of food that is
absorbed and therefore lowers calorie
intake. The combination of limiting the
amount of food taken in and reducing the
absorption of food greatly reduces food
Laparoscopic Sleeve Gastrectomy
This is a new bariatric procedure and is simply
the first part of a more complex bariatric
procedure called the duodenal switch. This is
primarily a restrictive procedure and does not
require adjustments as with the band. It is not
As a new procedure, limited information
is available regarding success with
long-term weight loss. Not all
insurances will cover this procedure.
Early data shows acceptable weight loss
between the band and the RYGB.
The duodenal switch is a procedure
typically reserved for patients with BMI
above 50. This offers the greatest
amount of weight loss and the highest
rate of co-morbidity resolution. It does
have potential for other health
complications that limit the use of this
procedure for certain patients.
Endoscopic Bariatric Revisional Procedure: Apollo Overstitch
For patients with previous gastric bypass, the appollo overstitch
procedure reduces pouch and stoma size. It is an incisionless, endoscpic
procedure done in an outpatient setting. It combines with lifestyle
changes and helps to avoid re-operation.

The endoscopic revisional procedures (Overstitch) for previous gastric
bypass patients help patients who have had previous procedures get back
on track. This procedure reduces the pouch size of patients with
previous gastric bypass. It also reduces the stoma size of patients with
previous bariatric procedures.
