Technical complications of Roux-en-Y gastrojejunostomy.

The Roux-en-Y gastrojejunostomy has become an increasingly popular technique for gastrointestinal tract reconstruction since it is purported to obviate many of the classic complications of the Billroth II gastrojejunostomy. In a review of over 900 Roux-en-Y gastrojejunostomies, seven patients with complications mimicking those seen with Billroth II reconstruction were identified. These complications included duodenal stump blowout, proximal blind loop or afferent loop syndrome, and bile-reflux gastritis. These complications resulted from technical problems in construction of the Roux-en-Y. Once the complications were diagnosed, they were amenable to operative correction. Recognition of the potential for these complications following Roux-en-Y gastrojejunostomy should aid in early diagnosis and treatment.
