Background: About one-third of patients undergoing a Roux-en-Y anastomosis develop Roux stasis syndrome, likely because of disordered electrical conduction. GI electrical stimulation has been previously used successfully in the management of postsurgical gastroparesis.
Objective: Endoscopic placement of temporary electrodes and GI electrical stimulation in the management of severe Roux stasis syndrome in a patient with esophagojejunostomy and to determine whether the patient would be a candidate for surgical permanent electrode placement.
Design: Case report.
Setting: Academic medical center.
Patients: This study involved a patient with Roux stasis syndrome.
Intervention: Upper encloscopy was performed, followed by endoscopic placement of two temporary electrodes, one each in the two jejunal limbs. Electrical stimulation was provided by an external stimulation device. The patient was re-evaluated 5 days later.
Main Outcome Measurements: Electrogastrogram (EGG) parameters including frequency, amplitude, and frequency-amplitude ratio and total symptom score and health-related quality of life score.
Results: There was a significant improvement in EGG parameters with electrical stimulation. Also, the patient had a marked improvement in total GI symptom score, from 11 to 4, with a dramatic improvement in the health-related quality of life score from -3 to +3.
Limitations: Single case report.
Conclusion: Endoscopic placement of temporary electrodes is feasible and safe. GI electrical stimulation of the jejunal limb is a potentially effective treatment for Roux stasis syndrome.
