Brief summary
The aim of this clinical trial is to assess the symptomatic efficacy and the impact on the utilization of healthcare resources of a treatment by gastric electrical stimulation (ENTERRA ®) in patients with refractory nausea and/or vomiting leading to a nutritional impairment. Eligible patients will be those with refractory symptoms either idiopathic, postsurgical or due to diabetes mellitus. The duration of the study will be 28 months for each patient. After a run-in period of 4 months during which a prospective assessment of healthcare resources utilization and of the severity of the symptoms will be obtained, patients will be implanted. The follow-up period after implantation of the device will last 24 months in every patients and will be divided in two parts: a) After the first postoperative month during which the device will remained on the OFF position, the first phase of the study will be a randomized double-blind cross-over study with 2 periods of 4 months during which the device will be activated or not. After the 9th month of follow up, the trial will be an open trial and the device will be activated in all patients. During the whole trial, patients will record all types of healthcare resources utilizations (hospitalizations, drug treatments, endoscopic procedures…) while the symptomatic efficacy of the treatment will be assessed by standard questionnaires at the following visits scheduled at 1, 5, 9, 12, 18, 24 months. The glycemic control will be determined at each visit in diabetic patients. A delayed gastric emptying will not be a selection criteria but we have planned to analyze the clinical results of the treatment in taking into account a delayed or normal gastric emptying during the pre-implantation period. Moreover, gastric emptying studies have been scheduled at 5, 9, 12 and 24 months to test the impact of gastric electrical stimulation on gastric emptying.
