Roux Stasis Syndrome in Conventional Roux-en-Y Gastrojejunostomy and Uncut Roux-en-Y Gastrojejunostomy after Subtotal Gastrectomy

ABSTRACT

PURPOSE: Roux stasis syndrome is the main complication of a Roux-en-Y gastrojejunostomy. The aim of this study was to compare the occurrence rate of Roux stasis syndrome with the passing of time in a conventional Roux-en-Y gastrojejunostomy and in an uncut Roux-en-Y gastrojejunostomy. MATENRIALS AND METHODS: 50 patients (31 men and 19 women) had a conventional Roux-en-Y reconstruction and 53 patients (35 men and 18 women) had an uncut Roux-en-Y reconstruction. The Roux stasis syndrome was defined by clinical criteria only. The criteria included one of the four following conditions at the time of follow-up chronic upper abdominal pain, postprandial fullness, persistent nausea, and intermittent vomiting that are worsened by eating. Follow-up after surgery was done in all patients at 7~12, 13~18, 19~24, 25~30, and 31~36 months. RESULTS: According to the criteria, the Roux stasis syndrome occurred in 40.0% of the patients at 7~12 months, 33.3% at 13~18 months, 35.3% at 19~24 months, 32.0% at 25~30 months, and 33.3% at 31~36 months after a conventional Roux-en-Y operation. The syndrome occurred in 22.6% of the patients at 7~12 months, 15.2% at 13~18 months, 17.1% at 19~24 months, 19.2% at 25~30 months, and 20% at 31~36 months after an uncut Roux-en-Y reconstruction. Conclusion: In terms of occurrence pattern, only a little variance existed one year after both procedures. Comparing the Roux stasis syndrome in both procedures, the uncut Roux operation had better results than the conventional Roux operation.
