Improvement of the Roux limb function using a new type of "uncut Roux" limb

Abstract

Background: The Roux stasis syndrome is characterized by symptoms of upper gut stasis following Roux-en-Y gastrojejunostomy. The aim of this study was to compare a new type of uncut Roux-en-Y gastrojejunostomy with the conventional Roux-en-Y gastrojejunostomy after subtotal gastrectomy.

Methods: 51 patients (31 men and 20 women) had the conventional Roux-en-Y reconstruction and 54 patients (38 men and 16 women) had the new type of uncut Roux-en-Y reconstruction. The new type of uncut Roux-en-Y gastrojejunostomy consisted of an artificial jejunal occlusion and a short Roux limb (20 to 30 cm).

Results: The criteria included one of the four following conditions at the time of follow-up: chronic abdominal pain, postprandial fullness, persistent nausea, and intermittent vomiting that are worsened by eating. According to the criteria, the Roux stasis syndrome occurred in 19 patients (37.3%) with conventional Roux-en-Y reconstruction, and in 10 patients (18.5%) with uncut Roux-en-Y reconstruction (P = 0.033).

Conclusions: A new type of Roux operation is able to alleviate not only the Roux stasis syndrome but also alkaline reflux gastritis or esophagitis by preserving motility of the Roux limb and diversion of duodenal juice from the gastric remnant.
