The objective of the present study was to assess the effectiveness of laparoscopic resection for RC, with an emphasis on perioperative variables and long\u2010term oncological outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This prospective study was carried out between January 2005 and September 2010 and included 513 patients diagnosed with RC who underwent laparoscopic surgery. Patients with locally advanced RC (cT3\/cT4 or N+) received neoadjuvant treatment. Adjuvant treatment was applied to patients with stage II\/III disease or according to the neoadjuvant protocol. All patients were followed\u2010up prospectively for the evaluation of complications and oncological outcome. Survival rate analysis was performed using the Kaplan\u2013Meier method.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Sphincter\u2010preserving surgery was performed on 389 patients, and the remaining 124 patients underwent abdominoperineal resection. Perioperative mortality occurred in only one patient (0.2 %), and 27 (5.3 %) intraoperative complications were recorded. The most common postoperative complication was anastomotic leakage (5.5 %). The conversion rate was 6.4 %. The mean number of harvested lymph nodes was 23.6 \u00b1 13. The mean distance to the distal margin was 2.6 \u00b1 1.9 (0\u20137) cm. Distal margin positivity was detected in 9 (1.7 %) patients. The circumferential margin was positive in 39 (7.6 %) cases. After a median follow\u2010up period of 30 (1\u201378) months, recurrence occurred in a total of 59 patients (11.5 %). Local recurrence was detected in 16 patients (3.1 %), and both local and distant recurrence was found in 7 patients (1.4 %). Distant recurrence only was detected in 43 patients (8.4 %). The overall 5\u2010year survival rate was 84 %, and the 5\u2010year disease\u2010free survival rate was 77.4 %. The local recurrence\u2010free survival rate was 98.4 % at 2 years, 95.7 % at 3 years, and 94.3 % at 5 years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our results, together with the review of the literature, clearly demonstrate that laparoscopic resection for RC is a feasible method at specialized high\u2010volume centers. The long\u2010term outcomes are at least as good as those from open surgery as long as the principles of oncologic surgery are respected and faithfully performed.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00268-013-1927-7","type":"journal-article","created":{"date-parts":[[2013,1,29]],"date-time":"2013-01-29T18:37:34Z","timestamp":1359484654000},"page":"883-892","source":"Crossref","is-referenced-by-count":16,"title":["Laparoscopic
