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

V Cigaina V et al. Obes Surg. 1996 Jun.

Abstract

BACKGROUND: This study was initiated 3 years ago when antral gastric 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 hours of kethamine anesthesia we paced the stomach by various patterns of electrical stimulation and obtained both forward and backward peristalsis, as well as gastric peresis. CONCLUSION: Variations in antral electrical stimulation produce characteristic patterns of forward and reverse peristalsis.
