Gastric Peristalsis Control by Mono Situ Electrical Stimulation: a Preliminary Study

  • Published:
Obesity Surgery Aims and scope Submit manuscript

Background: This study was initiated 3 years ago when antral gastric electric stimulation was first used successfully to reduce free feeding in swine. Methods: Three swine weighing 45 kg each were implanted with one subserosal bipolar electrode, positioned in the antrum, close to the pylorus, at the anterior side of the lesser gastric curvature. Results: During 4 h of kethamine anaesthesia we paced the stomach by various patterns of electrical stimulation and obtained both forward and backward peristalsis, as well as gastric paresis. Conclusion: Variations in antral electrical stimulation produce characteristic patterns of forward and reverse peristalsis.
