To investigate the clinical efficacy of stent implantation monitoring with endoscope and X-ray in the treatment of malignant obstruction of late esophageal carcinoma.

From June 2010 to October 2017, 67 patients with malignant obstruction of late esophageal cancer in the First Hospital of Hohhot, Inner Mongolia, were divided into the joint group (n=35) who underwent stent implantation monitoring with endoscope and X-ray, and the normal group (n=32) who underwent stent implantation monitoring with only X-ray. The quality of life and dysphagia index of the two groups were compared before operation and 1 to 3 months after operation. The postoperative complications were observed and relevant treatments were performed. The lifetime and survival rates of the patients were counted. Quality of Life Questionnaire-Core (QLQ-C30) and Esophageal Cancer Special Scale (OES-18) were used to investigate the life quality of the patients.

The stents were successfully implanted at the first time for the two groups with 100% success rate, and the dysphagia was immediately improved. The scores were improved from 3.3±0.6 and 3.2±0.7 points to 1.0±0.3 in the joint group and the normal group respectively. The scores after 1 week were improved to 0 point in the two groups. There were no major hemorrhages and perforations in the two groups during and after surgery. Both groups had varying degrees of retrosternal pain and discomfort, but most patients did not require special treatment. The survival time and life quality of the joint group were significantly better than those of the normal group (P<0.05), and the re-occlusion rate of the joint group was significantly lower than that of the normal group (P<0.05). There were no statistically differences in the stent relocation rate between the groups (P>0.05).

The application of stent implantation monitoring with endoscope and X-ray on the patients who suffer from late esophageal carcinoma and cannot undergo surgery has the advantages of small trauma, higher safety and accurate positioning, which can quickly relieve the symptoms, improve the life quality and prolong the survival time.
