Abstract: 【Abstract】〓Objective〓To compare the short-term effects of laparoscopic versus open Dixon radical resection for rectal cancer. Methods〓Eighty-four patients with rectal cancer were nonrandomly divided into two groups, the laparoscopic group(n=44) were treated with laparoscopic Dixon radical resection and the open group(n=40) with open Dixon raidcal resection. Short-term effects, including number of resected lymph nodes, distal resection margin, operative time, blood loss, postoperative anal exhaust time, length of stay, hospitalization expenses, and incidence of complications, were observed and compared between the two groups. Results〓The number of resected lymph nodes (12.91±3.58 vs 14.33±3.38) and distal resection margins (3.15±0.61 cm vs 3.28±0.74 cm) showed significanly differeces between the two groups (both P>0.05). Laparoscopic group was associated with significantly longer operative time (191.75±23.06 min vs 154.80±12.99 min), less blood loss (132.63±35.73 mL vs 181.02±75.79 mL), shorter postoperative anal exhaust time (2.93±1.33 d vs 4.70±1.39 d) and length of stay (11.38±2.00 d vs 16.82±1.85 d), and higher hospitalization expenses (36.9±3.0 thousand vs 30.3±3.7 thousand)(all P<0.05). Incidence of complications was found no difference between the two groups(9.1% vs 17.5%,P>0.05). Conclusion〓Laparoscopic Dixon radical resection is superior to open Dixon radical resection in the management of rectal cancer in terms of improving short-term efficacy.
