ABSTRACT
To evaluate the feasibility and safety of colon stenting as bridge surgery for colorectal cancer obstruction. Methods: A total of 30 patients (stent group), who underwent colonic stenting for colorectal obstruction at the Third Xiangya Hospital, Central South University from September 2015 to June 2017, were selected to receive the preoperative bridge surgery. Technical success rates, clinical success rates, and stent-related complications were observed. A total of 38 patients (emergency surgery group), who underwent surgical operation for colorectal obstruction, served as a control. The tumor resection rate at Stage I, ostomy rate, hospitalization time, and hospitalization cost were compared between the 2 groups. Results: The technical success and clinical success rates were 100.0% and 90.0% in the stent group, respectively. The stent-related complications included bleeding in 2 cases (6.7%), micro-perforation in 1 case (3.3%), stent displacement in 1 case (3.3%), and stent occlusion in 3 cases (10.0%) in the stent group. The Stage I tumor resection rate in the stent group was significantly higher than that in the emergency surgery group (90.0% vs 68.4%, P0.05). Conclusion: Preoperative colonic stenting for colorectal obstruction surgery as a bridge is feasible in terms of methods, and which can significantly increase the Stage I tumor resection rate, reduce the ostomy rate, decrease surgical complications, shorten the average length of hospital stay, and reduce patient suffering.

Objective:To explore the function of esophageal small balloon or papillary sphincter knife in the treatment of stent implantation for colorectal malignant obstruction,and to improve the success rate of colonic stent placement in such patients.Methods:A total of 49 patients with colorectal cancer complicated with almost complete obstruction or colorectal cancer were enrolled for this study.The esophageal small balloon or papillary sphincter knife was used in the guide wires.The guide wires gradually crossed the tumor gap and they were placed in the contralateral intestinal cavity with balloon progression.X-ray was then used to confirm whether the guide wire was inserted in the lesion intestinal cavity,and then the metal bare stent was inserted.Results:The guide wires was successfully inserted with conventional methods in these 49 cases,while they were also successfully placed the guide wire and the stent in the new way.Conclusion:For the patients with colorectal cancer complicated with complete obstruction or colorectal cancer located in obviously angled location,the use of esophageal small balloon or papillary sphincter knife can help the guide wire insert.They greatly improve the success rate of stent implantation.
