Abstract Background: The large-cell Niti-S stent is useful for multiple stenting in malignant hilar biliary obstruction (MHBO) patients. Recently, a novel uncovered self-expandable metallic stent (USEMS) (a large-cell Niti-S slim-delivery stent) was developed. In this study, we aimed to evaluate the efficacy of this slim-delivery USEMS in MHBO patients.Methods: Outcomes related to USEMS placement, clinical course, and patency period were evaluated in MHBO patients who received multiple USEMSs.Results: Fourteen MHBO patients underwent the placement of multiple USEMSs, including using the novel slim-delivery stent. Three patients had a past history of Billroth-II reconstruction. The number of USEMSs placed in each patient was 2-6. Three procedures were reinterventions. The new slim delivery system was used to place the first stent in three patients and an additional stent in the remaining patients. The technical and clinical success rates were both 100%. According to Kaplan-Meier analysis, the cumulative patency rate 50 days after USEMS placement was 87.5%.Conclusions: Placing multiple USEMSs in patients with a past history of abdominal surgery or in reintervention is difficult. The novel USEMS might overcome these difficulties and be the first choice for MHBO patients. TRIAL REGISTRATION: Not applicable

This article focuses on the famous novel Koshpendiler (1976) by Ilyas Esenberlin. This literary work occupies a special place in Soviet Kazakh literature because it raises important problems such as the foundation of the state and nation, the sense of territoriality, and the struggle against Russian colonizers. The authors argue that this historical novel can be considered as an example of post-colonial discourse. The novel itself is an extrapolation of the 1970s’ Soviet reality when national Union republics, including Kazakhstan, were seeking greater independence. Kazakh cultural elites and the intelligentsia turned to the past history of nation-building to address the problems of the present day. Not having an opportunity to openly express their views, the Kazakh establishment preferred to express their national sentiments through the historical genre. In this work, the authors suggest their own vision of Soviet national literature from political science and historical perspectives.
