Laparoscopic resection for rectal cancer: a case-matched study

Abstract
The field of laparoscopic rectal cancer surgery is expanding. We compare short-term and early oncological outcomes after laparoscopic versus open resection in carefully matched rectal cancer patients. All consecutive patients undergoing elective laparoscopic resection for rectal cancer were reviewed. Laparoscopic resections were matched 1:1 to open resections by age, gender, American Society of Anesthesiologists class, body mass index, neoadjuvant chemoradiation, and type of surgery. Data were analyzed using Fisher’s exact, chi-square, Wilcoxon rank-sum tests, and Kaplan–Meier estimates. P-value p = 0.02). Laparoscopic surgery had similar 30-day readmissions but shorter total length of hospital stay (5 versus 7 days, p < 0.01), time to first flatus (3 versus 4.5 days, p = 0.001), and time to first bowel movement (4 versus 5 days, p = 0.05) when compared with open surgery. The 3-year disease-free survival, local recurrence, and distant recurrence rates were also similar between the two groups. Laparoscopic surgery can be safely performed for rectal cancer, with better postoperative recovery and acceptable early oncological outcomes. Results from large ongoing randomized trials with longer follow-up time are pending to better define oncologic outcomes.
