Gastroesophageal reflux disease (GERD) refers to gastrointestinal diseases in which gastric and duodenal contents flow back into the esophagus, causing clinical symptoms and esophageal inflammation, thus seriously affecting the quality of life of patients, and even leading to esophageal precancerous lesions. Currently laparoscopic fundoplication has become the preferred surgical method for gastroesophageal reflux disease due to its outstanding advantages such as only reconstruction (no resection, no specimen collection), image magnification, good lighting, and good operation in narrow space.

The 3D printing dry lab model used in training course is independently developed by Ningbo TrandoMed 3D. Starting with CT scan and elastosonography to obtain the three-dimension data of human organ. Taking silicone as raw material, which has the same softness and tensile strength of human organ, 3D printing technology is utilized to print human organ.

The 3D printing dry lab model can closely simulate the stomach, esophagus and omentum on it in texture and structure.  In addition to simulating the key step of laparoscopy, we can customize organ model per patient’s CT data, thus providing patient-specific surgical training and effectively reduce unnecessary damage to patient.

Using 3D printing dry lab model to carry out laparoscopic fundoplication training can improve the operation skill level of the operator, reduce the damage to the patient’s body, with lower incidence of postoperative complications, and benefit the prognosis of the patient, which is worth popularizing.
