Objective To investigate the feasibility and therapeutic effect of stenting therapy by using modified Y-shaped self-expandable metal stent for the stenosis of gastroenteric stoma. Methods According to the particular anatomic structures and the pathological features of the narrowed gastroenteric stoma,the authors designed a modified Y-shaped self-expandable metal stent. Under the fluoroscopic guidance,implantation of modified Y-shaped self-expandable metal stent was performed in 5 patients with narrowed gastroenteric stoma. The technical safety and the clinical results were evaluated. Results The modified Y-shaped self-expandable metal stent was successfully implanted with one procedure in all five patients. After the implantation the symptoms such as nausea,vomiting,abdominal distension were promptly relieved,and the patients' living quality was markedly improved. Conclusion The stenting therapy with modified Y-shaped self-expandable metal stent can rapidly relieve the stenosis of gastroenteric stoma once for all. The technique is feasible and the short-term effect is reliable,therefore,it is worth popularizing this therapy in clinical practice.

Objective:To explore and analyze the application effects of multi-site Mini-clinical Evaluation Exercise (Mini-CEX) method in teaching of orthopedic nursing interns.Methods:From September 2019 to December 2019, a total of 97 nursing students who took an internship in 4 Orthopedic Wards of the First Affiliated Hospital of Zhengzhou University were selected as research objects. Among them, 45 nursing students who took an internship in the First Ward and the Second Ward of Orthopedics were set as the control group and other 52 nursing students who took an internship in the Third Ward and the Sixth Ward of Orthopedics were set as the observation group. The control group was given routine nursing instruction, while the observation group was given multi-site Mini-CEX method on the basis of the control group. Scores of all dimensions of Mini-CEX and scores of departmental rotation examination after the completion of teaching and the scores of teaching efficacy of teachers before and after the implementation of multi-site Mini-CEX method were compared between the two groups.Results:Scores of all dimensions and the total score of Mini-CEX of nursing interns in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . The scores of theoretical assessment and practical operation of departmental rotation examination of nursing students in the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . After the implementation of multi-site Mini-CEX teaching program, the general teacher efficacy, personal teaching efficacy and total scores of nursing teachers were higher than those before the implementation, and the differences were statistically significant ( P<0.05) . Conclusions:Application of multi-site Mini-CEX method in surgical nursing practice teaching can improve clinical skills, comprehensive ability and learning interest of nursing students, and also help to improve the teaching efficacy of teachers, which is worthy of promotion and application.
