Background And Objective:
Gastric electrical stimulation is a promising technology for treatment of gastroparesis. Few studies address potential complications of the device.
Materials:
We review the diagnosis and laparoscopic management of 2 cases of gastric stimulator (GS) electrode erosion through the gastric wall.
Results:
Both patients presented with late (16 and 21 mo) device infection. Diagnosis of electrode erosion was verified by upper endoscopy. The electrodes were successfully removed laparoscopically. A new GS and electrodes were implanted laparoscopically in 1 patient 6 months later.
Conclusions:
Electrode erosion is an unusual complication. Surgeons must have a high index of suspicion for electrode erosion when patients present with late GS infections. Eroded electrodes can be removed and replaced laparoscopically.
