ABSTRACT
Objective:To evaluate intestinal stenting in patients of left colon cancer complicated with acute intestinal obstruction and analyze its short-term and long-term efficacy.Methods:Sixty patients who suffered from left colon cancer complicated with acute intestinal obstruction at the First Department of General surgery, Chengdu Second People's Hospital from Sep 2016 to Sep 2019 were retrospectively enrolled. According to treatment methods, the patients were divided into the stent implantation staged surgery group (24 patients ) and the control group receiving emergency surgery (36 patients).Results:There was no significant difference in perioperative course between the two groups. There was no significant difference in three year overall survival rate or recurrence and metastasis rate between the two groups. Preoperative bowel preparation rate in stent implantation group was obviously higher than the control group (100% vs. 44%, P=0.000). The laparoscopic surgery rate of the stent implantation group was higher than the control group (21% vs. 0, χ2=9.857， P=0.002). The enterostomy rate of the stent implantation group was lower than the control group (0 vs. 19%, χ2=10.237， P=0.005). There was a higher rate of one-stage excision and anastomosis in the stent implantation group than in the control group (100% vs. 81%, χ2=7.760， P=0.005).There was a higher lymph nodes deissection rate in the stent implantation group than in the control group, [11(7-14) vs. 6(3-10), Z=-2.672， P=0.006]. Conclusions:For patients who suffered from left colon cancer complicated with acute intestinal obstruction, the intestinal stent can improve the bowel preparation to a greater extent, which can increase the proportion of one-stage anastomosis and reduce enterostomy rate.
