Atypical complications of gastric bypass surgery.
Although gastric bypass surgery continues to grow in popularity for weight loss and weight maintenance in the morbidly obese, there has been little attention given to the imaging of complications associated with these surgeries. The purpose of our study is to demonstrate the variety of gastric bypass surgery complications that can be identified radiographically, with attention to the more unusual complications. This study was performed with institutional Internal Review Board approval. We performed a 5-year retrospective review of all patients who had undergone gastric bypass surgery, had complications of the surgery, and had studies performed in our department to image these complications. These studies consisted of contrast fluoroscopy and CT. We identified the more common complications of anastomotic stenoses and anastomotic leaks. We also identified six unusual complications as follow: (1) internal herniation through the small bowel mesentery, (2) internal herniation through the transverse mesocolon, (3) external herniation through the abdominal wall incision, (4) enterocutaneous fistulas, (5) antiperistaltic construction of the Roux-en-Y, and (6) incorrect anstomoses of the Roux limbs resulting in a Roux-en-O configuration. Our findings show that a thorough understanding of expected postoperative bowel configuration is essential in the evaluation of these patients. In addition, fluoroscopic evaluation should assess not only anatomy, but also motility.

Enteroclysis and computed tomography enteroclysis.
Enteroclysis, the most detailed radiologic examination of the small bowel, can be a challenge for both patient and radiologist. This article broadly outlines the principal technical features of the standard enteroclysis procedure and discusses its diagnostic advantages and indications, as well as its limitations and difficulties. A comparative assessment of computed tomography-enteroclysis and the emerging magnetic resonance adaptation complements the survey of current approaches to radiologic small bowel diagnostics.
