Intestinal bypass surgery can lead to loss of weight effectively, but it can also lead to various complications that should not be neglected. About half of the patients who received this surgery need rehospitalization to manage the complications. [5] The expected outcomes and possible risks of the intestinal bypass surgery are shown as follows:
Jejunoileal bypass (JIB) was a surgical weight-loss procedure performed for the relief of morbid obesity from the 1950s through the 1970s in which all but 30 cm (12 in) to 45 cm (18 in) of the small bowel were detached and set to the side.
Vitamin B 12 deficiency is quite common after gastric bypass surgery with reported rates of 30% in some clinical trials. [journal 13] Sublingual B 12 (cyanocobalamin) appears to be adequately absorbed. In cases where sublingual B 12 does not provide sufficient amounts, injections may be needed. Protein malnutrition is a real risk.
Schematic of gastric bypass using a Roux-en-Y anastomosis. The transverse colon is not shown so that the Roux-en-Y can be clearly seen. The variant seen in this image is retrocolic, retrogastric, because the distal small bowel that joins the proximal segment of stomach is behind the transverse colon and stomach.
Bowel-associated dermatosis–arthritis syndrome (BADAS), is a complication of jejunoileal bypass surgery consisting of flu-like symptoms (fever, malaise), multiple painful joints (polyarthralgia), muscle aches and skin changes. It has been reported to occur in up to 20% of patients who had jejunoileal bypass surgery, a form of obesity surgery ...
Partial ileal bypass surgery is a surgical procedure which involves shortening the ileum to shorten the total small intestinal length. [ 1 ] First introduced in 1962 by Professor Henry Buchwald of the University of Minnesota, [ 2 ] the procedure is used to treat a number of hyperlipidemias including familial hypercholesterolemia .
Mason introduced the first gastric bypass surgery in 1966 and was the inventor of the first vertical banded gastroplasty surgery in 1980. [ 1 ] [ 7 ] [ 8 ] [ 4 ] [ 9 ] [ 10 ] : 39–46 [ 11 ] He was the founder of the American Society for Metabolic and Bariatric Surgery (ASMBS) and was its first president.
Risk factors for the development of bacterial overgrowth include dysmotility; anatomical disturbances in the bowel, including fistulae, diverticula and blind loops created after surgery, and resection of the ileo-cecal valve; gastroenteritis-induced alterations to the small intestine; and the use of certain medications, including proton pump ...
