Stenosis of the gastroenterostomy after LRYGBP is an infrequent but serious problem, which results in considerable morbidity.

Larger patients as measured by waist measurement, weight, and BMI but not previous surgery prolonged LRYGBP. Conversion to open surgery was more frequently necessary in patients with larger abdomens, central obesity, and type II diabetes. Complications did not correlate with any preoperative parameter measured.

Steatohepatitis, diabetes mellitus, adhesions from various causes, previous bile leaks, large waist size, BMI, and weight are predictors for conversion to open surgery.
