LAPAROSCOPIC GASTRIC BYPASS
Although LAGB and LSG are effective against most of our patient with morbid obesity, it still has its limitations.
Restrictive procedure cannot limit fluid calories and patients with poor compliance of dietary advice are at risk
of inadequate weight loss or pouch dilatation secondary to binge eating behavior. Gastric bypass, on the other hand,
is a hybrid procedure combining gastric partition (restrictive) and foregut bypass (malabsorptive). Firstly, we
divide the stomach into a small upper pouch and a much larger, lower "remnant" pouch, and then re-arrange the small
intestine to allow food to enter distal small bowel without passage of remnant stomach, duodenum and proximal jejunum.
There are two forms of reconstruction techniques.

Absorption of iron and Vitamin B12 is affected which may lead to anemia. Reduced the ability to absorb calcium
and may also lead to bone disease especially in post-menopausal women. However, most of these problems can be
prevent by vitamin and minerals supplements.
||since most of
the stomach is bypassed during surgery, any disease process (ulcer, cancer) will not be able to
examine by ordinary investigation tools (contrast X-ray, upper endoscopy).
