When removal of a polyurethane band is involved (polyurethane was predominantly used in the 1980s and 90s), it likely has built substantial scar tissue that must also be removed, depending on how long since the VBG took place. Removal of the staples involves stitching back together the previously separated parts of the stomach.
The restriction of the stomach also can be created using a silicone band, which can be adjusted by the addition or removal of saline through a port placed just under the skin, a procedure called adjustable gastric band surgery. [35] This operation can be performed laparoscopically, and is commonly referred to as a "lap band".
On February 14, 2009, the UK's first SILS implantation of a gastric band was performed by the pioneering surgeon Professor Franco Favretti and his Healthier Weight team. The patient, a 50-year-old female, received a gastric band (LAP-BAND) implanted through the umbilicus. The patient made an excellent recovery and was discharged the following day.
The gastric bypass reduces the size of the stomach by well over 90%. [4] A normal stomach can stretch, sometimes to over 1000 mL, while the pouch of the gastric bypass may be 15 mL in size. The gastric bypass pouch is usually formed from the part of the stomach that is least susceptible to stretching.
The surgical insertion of an adjustable gastric band is often referred to as a lap band procedure or band placement. First, a small incision (typically less than 1.25 cm or 0.5 in.) is made near the belly button .
Sleeve gastrectomy or vertical sleeve gastrectomy, is a surgical weight-loss procedure, typically performed laparoscopically, in which approximately 75 - 85% of the stomach is removed, [1] [2] along the greater curvature, [3] which leaves a cylindrical, or "sleeve"-shaped stomach the size of a banana.
The alkaline environment causes the retained gastric tissue to produce acid, which may result in ulcers in a rare complication known as retained antrum syndrome. All patients lose weight after gastrectomy, although the extent of weight loss is dependent on the extent of surgery (total gastrectomy vs partial gastrectomy) and the pre-operative BMI.
Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [ 1 ] [ 2 ] The condition is associated with dilated small blood vessels in the gastric antrum , which is a distal part of the stomach . [ 1 ]
