Long-term oncologic outcomes of laparoscopic surgery for splenic flexure colon cancer are comparable to conventional open surgery.

PURPOSE

Few studies about laparoscopic surgery for splenic flexure colon cancer have been published. This study aims to compare the short- and long-term outcomes of laparoscopic surgery for splenic flexure colon cancer with those of conventional open surgery.

METHODS

From January 2004 to December 2010, 51 consecutive patients who underwent curative resection for stages I-III splenic flexure colon cancer were enrolled. Thirty-three patients underwent laparoscopy-assisted colectomy, while 18 patients underwent conventional open colectomy. Short- and long-term outcomes of the 2 groups were compared.

RESULTS

There were no differences in baseline characteristics, intra- and postoperative complications. The laparoscopy group showed longer operation time (median [interquartile range, IQR]: 295.0 [255.0-362.5] minutes . 180.0 [168.8-206.3] minutes, P < 0.001). In the laparoscopy group, return of bowel function was faster (median [IQR]: 3 [2-4] . 4 [3-5], P = 0.007) and postoperative hospital stay was shorter (median [IQR]: 9 [8-11] . 10.5 [9-19], P = 0.026). There were no statistically significant differences in overall survival rate (84.3% . 76.0%, P = 0.560) or disease-free survival rate (93.8% . 74.5%, P = 0.078) between the 2 groups.

CONCLUSION

Laparoscopic surgery for splenic flexure colon cancer has better short-term outcomes than open surgery, as well as acceptable long-term outcomes. Laparoscopic surgery can be a safe and feasible alternative to conventional open surgery for splenic flexure colon cancer.
