Rendezvous Procedures in Small Bowel and Colon Rendezvous procedures, a combination of laparoscopic operation techniques and intraoperative endoscopy improve the feasibility of minimal invasive surgery and furthermore increase the patient’s comfort. Despite intensified preoperative diagnostic procedures the search for a source of bleeding in the short bowel is still a real challenge. Intraoperative enteroscopy still provides the gold standard to assess the whole length of the short bowel. Benign tumors and a selected group of malignant tumors of the upper and lower gastrointestinal tract that would not be treatable by sole endoscopic or laparoscopic resection can be treated by minimal invasive techniques. Indication, technique, and results of 34 combined laparoscopic-endoscopic rendezvous procedures in the lower gastrointestinal tract that were performed during a period of 10 years were described and discussed. The different applied procedures can be subdivided into assisted endoscopic resections (n = 10), endoscopically assisted wedge resections (n = 8), endoscopically assisted transluminal resections (n = 2) and endoscopically assisted anatomical resections (n = 14). In two cases the planned operative procedure had to be changed as the whole tumor could not be removed or there was an imminent risk of postoperative stenosis. One colon perforation was seen following a laparoscopically assisted endoscopic polypectomy. The perforated colon segment could be successfully resected laparoscopically. No other major intraoperative or postoperative complications were observed. All procedures proved to be safe. The technical and personal requirements should be installed in all clinics, especially in those which perform minimal invasive procedures at the gastrointestinal tract. For the benefit of the patient, the surgeon and internist performing endoscopic procedures in a clinic should overcome the fear to interact with each other.
