RESUMO
Objective To study the operational techniques and feasibility of superior rectal artery preserving laparoscopic resection of sigmoid colon carcinoma.Methods From Jan 2015 to Nov 2016,85 patients with sigmoid colon carcinoma were divided into artery preserving group (27 cases) and traditional surgical group (58 cases).Results The mean operation time was (283 ± 51) min,the mean lymph node dissection was (15 ± 8) and the mean blood loss was (62 ± 17) ml in the artery preserving group.The mean operation time was (179 ±e63) min,the mean lymph node dissection was (15 ±7) and the mean blood loss was (67 ± 17) ml in the traditional surgery group.The number of resected lymph nodes and blood loss had no statistical significance between these two groups (t =0.058,P ＞0.05).Longer operating time were observed in the retained vascular group as compared to the traditional surgical group (t =7.530,P ＜ 0.05).There was no anastomotic fistula in the retained vascular group,however,two anastomotic fistula cases occurred in the traditional surgical group (x2 =0.043,P ＞ 0.05).Conclusions Preservation of superior rectal artery was safe and feasible for laparoscopic resection of sigmoid colon carcinoma.
