Objective: This retrospective multicenter study compared short- and long-term results between Japanese patients with asymptomatic stage IV colorectal cancer who underwent palliative laparoscopic surgery (LS) versus those who underwent conventional open surgery (OS). Methods: Among 968 patients treated for stage IV colorectal cancer from January 2006 to December 2007 in 41 surgical units that were participating in the Japan Society of Laparoscopic Colorectal Surgery group, we studied 398 patients who received palliative resection of their asymptomatic primary colorectal tumor. Results: We analyzed data from patients undergoing LS (LS group, n=106) and OS (OS group, n=292). Fourteen (13.2%) LS group patients were converted to OS. Although the differences between groups for postoperative complications were not significant, the mean time to solid food intake and postoperative length of hospital stay for the LS group were significantly shorter than those for the OS group (2 vs. 3 days, p<0.0001; 13 vs. 16 days, p<0.0001, respectively). The LS group patients experienced a longer median survival time than that of the OS group (24.5 vs. 23.9 months, p=0.0357). Conclusions: Laparoscopic palliative resection (LS) offers advantages for short-term outcomes and no disadvantages for long-term outcomes. The use of laparoscopic procedures to treat asymptomatic, incurable stage IV colorectal cancer appears to be acceptable.
