For more than 20 years, Nissen Fundoplication has been a widely embraced surgical procedure that has become the gold standard surgical intervention for reflux disease.

3D Systems is proud to offer the first-ever virtual-reality hands-on simulation for Nissen Fundoplication for the Simbionix LAP Mentor.

Ideal for the training of general surgeons, gastrointestinal surgeons, and gastroenterologists, this module with highly realistic graphics allows users to practice the key steps of the Laparoscopic Nissen Fundoplication procedure for treatment of Gastro-Esophageal Reflux Disease (GERD), including dissection of peritoneal ligaments, and dissection of the short gastric vessels.

Trainees learn to prevent and manage potential complications such as bleeding from various vessels and damage to the esophagus, crura, stomach and spleen.

Task 1 – Incision of the Gastrohepatic ligament and revealing Esophagus and Crura

The task allows for practicing accurate peritoneal incision and dissection.

Provide the trainee an opportunity to incise a window into the gastrohepatic ligament, safely dissect the peritoneum, separating the esophagus and crura, and release the esophagus circumference by dissecting the phrenoesophageal ligament.

Task 2 – Division of the Short Gastric Vessels

The task allows for practicing an accurate and safe dissection of the gastrosplenic ligament, including its short gastric vessels, in order to later mobilize the stomach fundus and allow a floppy and safe fundoplication.

Both tasks include a comprehensive performance metrics.

Additional tasks are under development.
