Patterns of abnormal gastric pacemaking after sleeve gastrectomy defined by laparoscopic high-resolution electrical mapping
Background Laparoscopic sleeve gastrectomy (LSG) is increasingly being applied to treat
obesity. LSG includes excision of the normal gastric pacemaker, which could induce …

The impact and clinical implications of gastric surgery on the gastric conduction system
Chronic symptoms of gastric dysfunction are common following gastric surgery, but the
mechanisms underlying these have remained poorly understood. Disturbances of foregut …

Gastroparesis syndromes: Response to electrical stimulation
Abstract Background and Aims Factors underlying gastroparesis are not well defined, nor is
the mechanism of action of gastric electrical stimulation (GES). We hypothesized that GES …

Slow-wave coupling across a gastroduodenal anastomosis as a mechanism for postsurgical gastric dysfunction: evidence for a “gastrointestinal aberrant pathway”
Postsurgical gastric dysfunction is common, but the mechanisms are varied and poorly
understood. The pylorus normally acts as an electrical barrier isolating gastric and intestinal …
