- Laparoscopic procedures with extracorporeal creation of the bowel anastomosis. These procedures provide unique access to different parts of the bowel. The PPPD procedure provides access to the mucosal and serosal side of the jejunum. Colorectal surgery provides access to both the serosal and mucosal side of the colon and the terminal ileum is sometimes also accessible. We expect to include around 2 patients per week.
