Risks and Complications of Roux-en-Y Gastric Bypass
Bariatric stomach bypass surgeries are serious procedures with surgical and anesthesia risks that are common to all types of serious operations. In addition, after undergoing a roux-en-y stomach bypass, patients may experience certain specific complications, as follows.
Risk of Dumping Syndrome
The occurs when food in the stomach pouch is digested too quickly (eg. sugar, or highly refined foods) and passes too rapidly into the small intestine. It can also be caused by over-large amounts of food. Dumping syndrome is not a health risk per se, but typical symptoms (nausea, feeling faint, sweating and diarrhea) can be very distressful for patients.
Risk of Stomach-Staple Failure
As in all bariatric procedures involving transection of the stomach using a line of staples, roux-en-y bypass carries a risk of staple-line failure. Associated complications include leaks from staple breakdown, stomal stenosis and marginal ulcers.
Risk of Nutritional Deficiencies
Roux-en-y gastric bypass results in ingested food bypassing the main digestive tract, including the duodenum and a variable length of proximal jejunum. Thus bypass patients have an added risk of developing iron deficiency and vitamin B12 deficiency. Vitamin D and calcium absorption may also be reduced since the duodenum and jejunum are the preferential sites of absorption. Therefore, after roux-en-y stomach bypass, a life long program of supplementary multivitamins, vitamin B12 iron and calcium is mandatory for all patients.
After all malabsorption surgeries, like roux-en-y bypass, there is a period of intestinal adaptation during which bowel movements can be liquid and frequent. This bowel complaint, frequently accompanied by bloating, gas and foul smelling stools may reduce with time, but occasionally is a permanent condition.
