[Update on Gastric Pacemaking: Relevance for Gastroparesis].

Gastroparesis is a disease in which gastric emptying is significantly decreased in the absence of a mechanical obstruction of the gastric outlet. In addition to conservative or pharmacological treatment options, gastric electrical stimulation (GES) is a possible alternative therapy for refractory courses of the disease. However, the available data from randomised controlled trials on efficacy do not permit an unqualified recommendation. The aim of this review is to introduce the clinical picture of gastroparesis, including the underlying pathophysiology, and to classify the therapeutic role of GES, based on the currently available literature. In particular, indications and limitations of the therapy are outlined that may lead to optimisation of the therapy, followed by an outlook on a potential new therapeutic procedure.
