Acupuncture for Postoperative Gastric Emptying Delay

This multicenter clinical trial, conducted at Qilu Hospital of Shandong University and collaborating institutions, prospectively assesses the efficacy and safety of acupuncture for postoperative delayed gastric emptying. Eligible participants will be prospectively enrolled and randomized into different groups per the study protocol. The primary endpoint is the reduction in the duration of delayed gastric emptying, while secondary endpoints include the complete resolution of cardinal gastroparetic symptoms, such as abdominal distension, nausea, and vomiting. All study procedures adhere to the ethical standards outlined in the approved protocol.

Laparoscopic Implantation of a Gastric Pacemaker in the Treatment of Gastroparesis

Gastroparesis is a burdensome condition that is caused by abnormal motor function of the stomach that results in delayed gastric emptying. It typically manifests with bloating, nausea, vomiting, abdominal pain, and even excessive weight loss and dehydration. The most common causes of gastroparesis are idiopathic, diabetic, medication-induced or iatrogenic (postsurgical) gastroparesis. Implantation of a gastric neurostimulation device is a surgical option to improve gastric emptying in patients with medication-refractory gastroparesis. Enterra® system is a gastric electrical stimulation that sends mild pulses through leads implanted in the stomach wall that stimulate gastric smooth muscles and nerves in order to improve symptoms and quality of life. Aim of the investogators' registry trial is to evaluate the feasibility and efficacy of laparoscopic gastric pacemaker implantation for electrical stimulation (Enterra® system). Primary endpoints of the study are symptom severity, health-related quality of life, and frequency of hospitalization before and after pacemaker implantation, perioperative complication rate, and cost effectiveness.
