Surgical Procedures

Roux-en-Y Gastric Bypass

Vertical Banded Gastroplasty

Lap Band

Roux-en-Y Gastric Bypass - this is a combination of a restrictive and malabsorptive procedure.

the upper portion of the stomach is freed and a row of staples is placed horizontally a few centimetres below the oesophagus - stomach junction. The gastric pouch measures about 1-2 ounces and is totally separated from the stomach.
the small bowel is divided approximately 24 inches beyond the stomach. The distal loop is brought up and attached to the stomach pouch. This forms the food channel.
the proximal loop contains secretions of bile and pancreas and is called the biliopancreatic channel. This channel is attached to the side of the food channel approximately 24 inches distal to the attachment of the stomach and small bowel forming a Y-shaped arrangement of the bowel.
In this procedure food intake is restricted because of the small stomach pouch and there is poor absorption of food because the bile and pancreatic secretions do not come in contact with food until about 48 inches beyond the stomach.

Vertical Banded Gastroplasy - this is a restrictive type of procedure. Food intake is reduced because the stomach is smaller. A vertical (up and down) pouch is constructed using the upper part of the stomach usually by using a surgical stapler. The pouch usually allows only 1-2 ounces of food to enter the stomach. This pouch may be surrounded by cloth mesh to prevent the stomach from distending.

Adjustable Gastric Band (Lap Band) - restrictive gastric operations, such as an adjustable gastric banding procedure, serve only to restrict and decrease food intake and do not interfere with the normal digestive process.

In this procedure, a hollow band made of special material is placed around the stomach near its upper end, creating the small pouch and a narrow passage into the larger remaining portion of the stomach. This small passage delays the

emptying of food from the pouch and causes a feeling of fullness. The band can be tightened or loosened over time to change the size of the passage. Initially, the pouch holds about 1 ounce of food and later expands to 2-3 ounces.

MidBand

There are several operations for morbid obesity. Most procedures are carried out under general anaesthesia through a midline (along the center line) abdominal incision. Vertical Banded Gastroplasy - this is a restrictive type of procedure. Food intake is reduced because the stomach is smaller. A vertical (up and down) pouch is constructed using the upper part of the stomach usually by using a surgical stapler. The pouch usually allows only 1-2 ounces of food to enter the stomach. This pouch may be surrounded by cloth mesh to prevent the stomach from distending.

The MIDBAND is an adjustable peri gastric belt, implantable by colonoscopies. It is indicated for surgical treatment of morbid obesity defined by an index of mass in excess of 40 kg/m2.

The MIDBAND provides a very attractive alternative to conventional surgical methods which are intense and irreversible, requiring extended hospitalization.

The MIDBAND is extremely flexible making it easy to fit. It’s inextensible and original fit double closure system insures a fastening capacity far in excess of the physiological conditions recurred. The MIDBAND has no sharp edges or irregularities preserving the gastric wall intact, even in event of rubbing. It is opaque to X rays, making it easy to locate and adjust.
