  • Title: Roux-limb motility after total gastrectomy and Roux-en-Y anastomosis in patients with Zollinger-Ellison syndrome.
    Author: Mathias JR, Khanna R, Nealon WH, Browne RM, Reeves-Darby VG, Clench MH.
    Journal: Dig Dis Sci; 1992 Apr; 37(4):545-50. PubMed ID: 1551344.
    Abstract:
    The Roux-en-Y syndrome was defined as chronic nausea, intermittent vomiting, and chronic abdominal pain worsened by eating in patients who have undergone a gastrojejunostomy Roux-en-Y reconstruction for peptic ulcer. When these patients fasted, the Roux limb showed striking abnormalities in motor function; when postprandial, they failed to convert to normal fed-state motor activity. In contrast, patients with Zollinger-Ellison syndrome do well after similar surgery; they can eat most foods and maintain their body weight. We studied the motility of the Roux limb and jejunum in six patients with Zollinger-Ellison after an esophagojejunostomy Roux-en-Y anastomosis. Roux-limb motor activity in these patients, as characterized by the migrating motor complex, was more frequent, well organized, and in synchrony with the remaining jejunum; most subjects also converted to the fed state after a liquid meal. We suggest that the enteric nervous system is intact and functions normally in patients who have had a Roux-en-Y reconstruction for ulcer disease secondary to Zollinger-Ellison, but not in patients with idiopathic peptic ulcer disease.
