Development of Magnetic Anastomat for Laparoscopic Bilioenterostomy

This work introduces the design and operating procedure of a novel magnetic anastomat for laparoscopic bilioenterostomy. Three techniques (magnetic compression technique, mechanic control technique and purse string suture technique) are used to design this device. The anastomat is mainly composed of two parts, a magnetic head and a handle. The surgical procedure for laparoscopic bilioenterostomy with this novel anastomat is similar to performing an end-side enteroenterostomy with the circular stapler. After the anastomosis is achieved, the magnetic head is placed at the anastomoses to maintain the digestive tract continuity. The magnetic head would fall into the jejunal lumen when the anastomoses is formed. This surgical approach would bring an innovation to the laparoscopic bilioenterostomy. Performing laparoscopic bilioenterostomy with this magnetic anastomat is safe, reliable and feasible.
