Efficacy of intestinal obstruction stent combined with laparoscopic surgery and neoadjuvant chemotherapy in patients with obstructive colorectal cancer.

There is still controversy on the surgical treatment of obstructive colorectal cancer worldwide. No accurate research has been reported to propose which method is the most suitable for patients with obstructive colorectal cancer. Therefore, comparison of efficacy of intestinal stent and trans-anal ileus catheter combined with laparoscopic surgery and neoadjuvant chemotherapy respectively in patients with obstructive colorectal cancer was carried out to provide reference and guidance for the selection of surgical schemes for patients with obstructive colorectal cancer. In total 89 patients with obstructive colorectal cancer treated in the Taizhou Hospital of Zhejiang Province, Wenzhou Medical University, from February 2016 to March 2017 were selected for retrospective analysis. Forty-nine cases treated with intestinal metal stent implantation combined with laparoscopic surgery and neoadjuvant chemotherapy were the stent group. The other 40 cases treated with trans-anal ileus catheter combined with laparoscopic surgery and neoadjuvant chemotherapy were the catheter group. The intestinal preparation time, surgical duration, intraoperative blood loss, open surgery rate, postoperative exhaust time and adverse reaction rate were compared between the two groups. All the patients were followed up with reexamination at 1 year in hospital to record the local recurrence rate and tumor implantation rate of incision. The intestinal preparation time in the stent group was shorter than that in the catheter group (P<0.001). The surgical duration in the stent group was longer than that in the catheter group (P<0.001). The intraoperative blood loss in the stent group was higher than that in the catheter group (P<0.001). However, there was no significant difference in open surgery rate, postoperative exhaust time, adverse reaction rate, local recurrence rate or incision tumor implantation rate between the two groups (all P>0.05). Therefore, intestinal metal stent implantation can effectively relieve intestinal obstruction, while trans-anal ileus catheter has higher safety in laparoscopic surgery. Their combination with neoadjuvant chemotherapy and laparoscopic surgery for obstructive colorectal cancer has high value and clinical effect. The best treatment plan should be selected according to the patient's condition.
