“…In the largest study of 86 cases with silicone Y-stent placement, 21 reportedly required an additional straight stent placement for improved palliation [4]. The Y-stent can also be used for airway stenosis around RC 1 [6]. This method is particularly effective for maintaining the airway patency of the right upper lobe bronchus.…”

“…Before placing the stents, the airway lumen should be re-established by a bronchoscopic procedure combining argon plasma coagulation, electrocautery, balloon dilatation or rigid bronchoscopic debulking [7]. After that, the length and diameter of the stenosis are assessed using a flexible and rigid bronchoscope, an endobronchial ultrasonic probe with a balloon, as well as preprocedural static images as previously described [6]. …”

“…Among many types and shapes of stents, the bifurcated silicone stent (the so-called Y-stent) provides effective palliative treatment for patients with main carinal stenosis [3,4]. Additionally, this stent is also useful for patients with airway stenosis around the carina between the right upper lobe bronchus and the bronchus intermedius (right carina 1, RC 1; nomenclature proposed by Prakash and Fontana) [5,6]. The Y-stenting technique on RC 1 enabled us to maintain the patency of the right upper lobe bronchus.…”

The silicone stent has been widely used to re-establish airway patency for patients with airway stenosis. The ideal shape of the stent should be well adapted to the tracheobronchial anatomic structures, and its optimal length should cover the entire inner wall of the stenotic airway. Although the silicone Y-stent was developed as a dedicated prosthesis for main carinal stenosis, we often encounter patients with tracheobronchial stenosis that cannot be treated by a single silicone Y-stent. The present study reports 2 cases of malignant disease who underwent double Y-stent placement on the involved carina between the right upper lobe bronchus and the bronchus intermedius as well as on the involved main carina as a unit. The procedure provided successful palliation.

“…Additionally, the tumour or granulation tissue is likely to protrude into the stent lumen from the window. To overcome these drawbacks, we reported a technique in which a Dumon Y-stent was placed in RC1 [12]. Afterward, we developed the double Y-stenting technique so as to treat the stenotic airway around both the main carina and RC1 [10].…”

“…cases with the tumour extending from the peripheral bronchus) were revealed by flexible bronchoscopes [11], and we did not consider as having indications for stenting. The size and length of the stent are decided using a flexible bronchoscope, endobronchial ultrasound with a balloon and pre-procedural computed tomography as previously described [12]. The Y-stents are designed to fit the anatomical structure of bronchi around the main carina, and so the left limb of the Y-stent branches off at an acute angle from the tracheal limb compared with the right limb.…”

The purpose of the present study was to evaluate the feasibility, efficacy and safety of the double Y-stenting technique, by which silicone Y-stents are placed on both the main carina and another peripheral carina, for patients with tracheobronchial stenosis.Under general anaesthesia, using rigid and flexible bronchoscopes, a Dumon TM Y-stent (Novatech, La Ciotat, France) was first placed on the primary right or secondary left carina followed by another Y-stent on the main carina so as to insert the bronchial limb of the stent into the first Y-stent. Patients who underwent double Y-stent placement during 3 yrs and 1 month in a single centre were retrospectively reviewed. In the study period, 93 patients underwent silicone stent placement and 12 (13%) underwent double Y-stent placement (11 for right and one for left bronchus). A combination of Y-stents, 14610610 mm and 16613613 mm in outer diameter, were most frequently used. Dyspnoea was relieved in all patients. Six out of seven patients with supplemental oxygen before stent placement could be discharged without supplemental oxygen. Median survival after stenting was 94.5 days. One pneumothorax and one granuloma formation occurred. Double Y-stent placement for patients with tracheobronchial stenosis was technically feasible, effective and acceptably safe.
