[Laparoscopic surgery in colorectal tumors].

The minimally invasive technique, by means of the undoubted advantages of the method, has become fully accepted in the surgical treatments of the most benign and functional diseases. Today it has been proven that the laparoscopic technique is safely usable also in the surgical treatment of colorectal tumors. The authors, analyzing their own and the international experiences, present the laparoscopic surgical treatment of colorectal tumors. Seventy-four patients were treated with laparoscopic-assisted colorectal intestinal resection in the Department of Surgery of the University of Szeged between January 1, 2005 and December 31, 2008. The surgical indication was neoplastic colorectal lesion in 40 cases. The average age of them was 64 years (from 36 to 89 years). Four patients belonged to the risk group of ASA I, 11 patients to ASA II, 24 to ASA III, and one to ASA IV. Twenty-six patients underwent rectosigmoideal resection, 2 had rectal exstirpation, 9 had right hemicolectomy and one had left hemicolectomy. There were no surgical or postoperative complications. Four conversions and in one case a reoperation occurred due to adhesion ileus. The startup of the passage (2.4 days, on average) and the possibility of nourishing per os were significantly shortened. The histological processes of specimens justified tumor-free oral, aboral and circumferential resection in all cases. Summarizing our own and international experiences it can be stated that the laparoscopic surgeries performed due to colorectal tumors are safe, and are also appropriate with respect to oncosurgery. There are a number of benefits for the patients mainly in the early postoperative period (faster recovery, shorter hospitalization) and their long-term survival results are good as well.
