Background
Bariatric surgery is on the rise worldwide.
It is increasingly being performed to control morbid obesity that is resistant to medical intervention.
Plain radiographs,
upper abdominal fluoroscopy and abdominal computed tomography are the most common imaging modalities used to asses postoperative patients.
The most common bariatric procedures performed include:
1.
Laparoscopic Roux-en-Y gastric bypass surgery
A small part of the stomach is used to create a new stomach pouch.
The smaller stomach is connected directly to the middle portion of the jejunum,
bypassing the rest of the stomach and the upper portion of the duodenum.
2.
Laparoscopic adjustable gastric banding
Gastric band was the commonest operation performed 10 years ago in Europe,
US & Australia,
it comprised 45% of total surgeries,
as it had a favourable risk profile.
Now Gastric sleeve and bypass are the commonest.
3.
Laparoscopic sleeve gastrectomy
The stomach is reduced to about 15% of its original size,
by surgical removal of a large portion of the stomach along the greater curvature.
This creates a sleeve like structure.
This procedure permanently reduces the size of the stomach.
4.
Intra-gastric balloon
This is becoming increasingly more common.
However up to 10% of patients experience balloon intolerance.
