AIM: T4 colorectal cancer remains a contraindication for laparoscopy. It is argued that the risk of incomplete resection could be higher than in open surgery. Furthermore, difficulty in dissection could lead to a very high rate of conversion. There is little information on this. The study aimed at assessing feasibility and operative and oncologic results of laparoscopic resection for T4 colorectal cancer. METHOD: Between 2006 and 2009, 39 patients with colorectal cancer with suspected involvement of another organ (T4) on computed tomography scanning and/or magnetic resonance imaging were included. The cancers were in the right colon (n = 18), left colon (n =9) and rectum (n = 12). The distribution of possible organ involvement was abdominal or pelvic side-wall (n = 21), urinary bladder (n = 4), small bowel or colon (n = 6), vagina and ovary (n = 3), prostate or seminal vesicles (n = 3) and duodenum (n = 2). RESULTS: The overall conversion rate was 18%. Postoperative mortality and morbidity were 2.5 and 33%, respectively. Clinical anastomotic leakage rate was 15% (n = 6). Abdominal reoperation was required in three (7%) patients. Pathological invasion to other organs (pT4) was confirmed in 30 (77%) patients. The R1 resection rate was 13% (4 of 30). After a median follow up of 19 months (range 1.5-45 months), the overall survival and disease-free survival rates were 97 and 89%, respectively. CONCLUSION: This study suggests that laparoscopic surgery is feasible for colorectal T4 cancer resection. Laparoscopy cannot therefore be considered an absolute contraindication for T4 colorectal cancer.
