Laparoscopic insertion of gastric electrodes for electrical stimulation

Area of Science:

• Minimally Invasive Surgery
• Gastroenterology
• Medical Devices

Background:

• Refractory gastroparesis significantly impacts patient quality of life.
• Traditional surgical implantation of gastric electrical stimulation (GES) wires requires laparotomy.
• GES offers symptomatic relief for patients with severe gastroparesis.

Purpose of the Study:

• To describe and illustrate the laparoscopic technique for implanting GES wires.
• To evaluate the safety and efficacy of laparoscopic GES wire insertion.
• To assess outcomes in patients undergoing laparoscopic GES implantation.

Main Methods:

• A detailed description of the laparoscopic technique using four ports.
• Intraoperative endoscopy for lead placement verification.
• Data collection on patient demographics, operative details, and postoperative morbidities for 31 consecutive patients.

Main Results:

• All 31 procedures were successfully completed laparoscopically with a mean operative time of 114.4 minutes.
• No perioperative mortality occurred.
• Postoperative complications included two cases of cellulitis and two generator repositionings due to pain; no hardware removal was necessary.

Conclusions:

• Laparoscopic insertion of GES wires is a safe and effective alternative to laparotomy for treating refractory gastroparesis.
• The technique is feasible even in patients with prior abdominal surgery.
• Further long-term follow-up and multicenter trials are ongoing to confirm efficacy.
