About this study
Official title: Combined Application of 3D Printing Technology and Robotic Surgery in Radical Gastrectomy of Gastric Cancer
The incidence of gastric cancer is the highest in China, and surgery is one of the most effective treatment methods. Da Vinci robot radical gastrectomy for gastric cancer has the advantage of minimally invasive and fine operation. However, due to complicated perigastric anatomy, abundant blood supply and wide distribution of lymph nodes, it is widely used in clinical use of .Combine the 3D printing technique with imaging examination (digestive endoscopy,3Dct cta/ctv, etc.) ,making the 3D model of da Vinci robot assisted radical gastrectomy can fully show the anatomical relationship around gastric cancer, determine the flow and variation of splenic portal vessels, and the distribution of splenic hilar lymph nodes. In order to eliminate the imagination difference of spatial anatomical structure before operation, it is easier for surgeons to optimize the operation plan, to control the operation process and to improve the accuracy, and to adopt individualized operation suitable for the patients.
Read the detailed description
The investigators will work with general surgery, imaging department and 3D printing center to try to print gastric cancer model and guide the operation. After obtaining the approval of the Hospital Ethics Committee, 20 patients with gastric cancer were collected for imaging examination and evaluation, and the normal physical model of 70% normal volume was printed with Guang Min resin material.The investigators will analyse the anatomical relationship between the tumor and surrounding tissues,and determine the range of tumor excision and the feasibility and safety of radical gastrectomy with Leonardo da Vinci robot for gastric cancer.Through the assistance of the 3D model,The investigators will select the suitable operation path to determine the extent of tumor excision and lymph node dissection.Furthermore, 3D print model is used to provide real-time navigation for key steps of surgery. The purpose of this research is to observe the application value of 3D printing technique in gastric cancer laparoscopic surgery with Leonardo da Vinci robot radical gastrectomy, and to provide reference for the development of 3D printing model of other complicated digestive tract surgery.

operation time (time frame: 1 hours to 6 hours through the surgery completion). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jul 2018.
