Comparison between midline incision and limited right skin crease incision for right-sided colonic cancers

Abstract

We compared the postoperative recovery parameters between patients undergoing curative surgery for right-sided colonic carcinoma using a limited skin crease incision and a traditional midline incision. A retrospective study was carried out analyzing clinical records and histopathological reports for all patients operated in one colorectal surgical unit for cancer of the right colon over a 2-year period. Palliative procedures were excluded. We analyzed demographic details, operative data (length of incision and time of operation), recovery parameters (time to parenteral analgesia, time to first oral fluid intake, time to first solid meal, time to discharge) and oncological parameters (lymph node harvest and resection margins). A total of 123 patients were analyzed, 61 with a midline incision and 62 with a skin crease incision. Demographic and tumour data (number of lymph nodes resected and resection margins) as well as postoperative complications were similar between the two groups. Wound length was significantly longer in the midline incision group (median, 20 cm vs. 10 cm; pp0.0005). With regard to postoperative recovery, the skin crease incision group had a significantly quicker return of bowel function (pppp<0.0005) than the midline incision group. There was no statistically significant difference between the two groups concerning postoperative narcotic requirements. In conclusion, the limited skin crease approach for right colon cancer resection is technically feasible and safe. It can achieve the same standards of tumour resection and clearance as the vertical midline approach while reducing postoperative recovery.
