AIM:To evaluate the clinical efficacy and safety of the silk thread traction intubation as a rescue technique for intraoperative silicone stent perforation during RS bicanalicular lacrimal intubation, and to clarify the value of technical innovation and promotion in primary care.METHODS: A retrospective analysis was conducted on patients with silicone stent perforation and failed conventional RS intubation treated at the Department of Ophthalmology, the Second People's Hospital of Changzhou from July 2022 to June 2025. All patients underwent reconstruction of the physiological lacrimal-nasal passage using Zhang's memory guidewire lacrimal probing and guiding needle. Repositioning and implantation of the damaged silicone stent were completed via 3-0 silk thread traction. Standard follow-up was performed for at least 6 mo postoperatively. Intraoperative and postoperative conditions of the patients were observed.RESULTS: A total of 21 patients(21 eyes)were enrolled in this study, including 6 males and 15 females, with a mean age of 59.6±10.8 y. The intraoperative salvage intubation success rate was 100% for all 21 eyes. Among them, 3 eyes required immediate removal of the silicone stent after implantation(1 eye developed a nasal corneal ulcer requiring priority treatment of ocular infection; 2 eyes had intolerable epiphora and discomfort and requested stent removal voluntarily). The remaining 18 eyes had no re-displacement or stent prolapse during indwelling, and the stents were successfully extracted after 3 mo of indwelling as scheduled. The complete lacrimal patency rates at 1, 3 and 6 mo after successful silicone stent implantation were 95%(20 eyes), 90%(19 eyes)and 81%(17 eyes), respectively. At 6 mo postoperatively, 17 eyes(81%)presented complete lacrimal passage patency, 3 eyes(14%)showed incomplete lacrimal patency, and 1 eye(5%)had complete obstruction. Postoperative complications included mild lacrimal puncta tearing in 2 eyes, lacrimal puncta granulation hyperplasia in 1 eye, and lacrimal puncta eversion in 1 eye. Among the 3 eyes with immediate silicone stent removal, only 1 eye developed recurrent lacrimal passage obstruction at 3 wk postoperatively, which was effectively treated by re-intubation. The remaining 2 eyes were cured without aggravation of corneal ulcer, lacrimal stenosis, or persistent lacrimal obstruction.CONCLUSION: The silk thread traction intubation represents a safe, efficient and minimally invasive salvage approach for stent perforation during RS lacrimal intubation. With the advantages of precise localization, high operative efficiency and minimal tissue damage, it greatly increases the success rate of silicone stent repositioning and reintubation accompanied by manageable complications.

Objective:To explore the effect of mobile medical intelligent software combined with OBE-CBCL dual-track teaching method in standardized training of orthopaedic residents.Methods:The orthopedic residents who received resident standardized training in our hospital from Jan 2022 to Sep 2022 were selected as the study subjects.The orthopedic residents who received regular teaching method from Jan 2022 to Mar 2022 were group A,orthopedic residents who received mobile medical intelligent software + regular teaching method from Apr 2022 to Jun 2022 were group B,and the orthopedic residents who received mobile medical intelligent software + OBE-CBCL dual-track teaching method from Jul 2022 to Sep 2022 were group C.All three groups participated in the relevant professional theoretical knowledge assessment,Mini-CEX,and satisfaction survey at the time of discharge.Results:The scores of professional theoretical knowledge assessment in groups B and C were higher than that in groups A,and it was higher in group C than that in group B(P＜0.05).The scores of each item of Mini-CEX in groups B and C were higher than those in group A(P＜0.05).Except for clinical judgment ability,the scores of the other items of Mini-CEX in group C was higher than those in group B(P＜0.05).In the satisfaction survey,the scores of deepening knowledge mastery in groups B and C were higher than that in group A,and that in group C was higher than that in group B(P＜0.05).The scores of improving clinical thinking and stimulating learning interest in groups B and C were higher than those in group A(P＜0.05),and the scores of improving team assistance and overall satisfaction in group C were higher than those in groups A and B(P＜0.05).Conclusion:Mobile medical intelligent software combined with OBE-CBCL dual-track teaching can significantly improve teaching effect of orthopaedic resident standardized training.

ABSTRACT:Objective To investigate the nursing methods of artificial lens implantation by three points suspension in the treatment of aphakic eye.Methods 12 cases with aphakic eyes were included in this study.XLSTABI -SKY foldable artificial lens was implanted by suspension of three points in the second phase,and all the patients was followed-up by more than six months. Preparation before operations,human-based nursing during operations and individualized nursing after operations were done and complications were observed.Results Through the operation and special nursing,each patient got a better corrected visual acuity than that before operation,en-dothelial decompensation and endophthalmitis of artificial artificial lens were not observed.Conclu-sion Special nursing and education for patients with implantation of foldable artificial lens sus-pended by three points could improve visual acuity and satisfactory consequences.
