[Laparoscopic rectum resection with truncal ligation of the inferior mesenteric artery and mesorectal excision].

Laparoscopic techniques in surgical treatment of colorectal cancer are performed present in prospective trials. Operation times are clearly decreasing with growing surgical experience and oncological criteria concerning resection margins and lymphatic dissection are comparable with open surgery. Indications for laparoscopic rectal resections are the endoscopic non removable adenoma and cancer of the upper and lower rectum endosonographic up to maximum uT3-stage. All laparoscopic resections are performed under conventional oncological criteria: after exploration of the abdominal cavity and laparoscopic ultrasound of the liver we perform the ligature of the inferior mesenteric vein and artery. Dissection and resection of the mesorectum is done by the Harmonic Scalpel. The rectum is taken out by mini laparotomy and anastomosis is done by transanal stapler.
