To discuss the clinical application of improved terminal ileum suspension in laparoscopic radical resection for low-rectal cancer.

From July 2017 to July 2019, ninety pantients with low rectal cancer who underwent laparoscopic operation in the First People’s Hospital were randomly divided into three groups: Group A (30 cases) received laparoscopic radical resection of recral cancer (Dixon); Group B (30 cases) received Dixon and preventive ileostomy; Group C (30 cases) received Dixon and improved terminal ileum suspension. Peripheral blood nutritional indicators and the levels of electrolytes of three groups were observed 1 d before operation and 1, 3 and 7 d after operation. The three groups were compared in terms of first getting out-of-bed time, first exhaust time, postoperative hospital stay, total cost for hospitalization and postoperative complications.

The absorption and utilization of nutrients and electrolytes were not significantly changed by different operation methods. First exhaust time was earlier in the group B (F=0.004, P<0.05). Compared with 3.33% (1/30) of group A and group C, there-operation rate increased obviously (100.00%) (χ2=81.562, P<0.001). There were 1 case of incision infection and 1 case of anastomotic leakage (6.67%) in group A, 2 cases of stoma related complications (6.67%) in group B and 1 case of anastomotic leakage (3.33%) in group C. No statistical differences were shown in first getting out-of-bed time, postoperative hospital stay, total cost for hospitalization, postoperative complications among the three groups.

Improved terminal ileum suspension is simple to operate, and does not affect the postoperative recovery of patients, effectively reducing the rate of small intestinal stoma closure operation, relieving the psychological pressure caused by stoma and the economic stress of secondary surgery.
