“…Several studies have shown the efficacy of silicone or metallic stents for the management of AC after LT [ 20,23,26,[29][30][31][32], but to our knowledge, this is the first study evaluating the role of OSMBS on a large patient population. Our study, along with previously reported data from case series [10][11][12][13], lends support to the feasibility, safety, and efficacy of these stents with a successful placement in 90%, with objective improvement in pulmonary function studies. The anatomy of the SC on both sides is more complex than that of the main carina.…”

“…Management of long-term complications from customized bifurcated stent (CBS) on SC in patients with longer life expectancy remains unclear [9]. To date, only 4 publications [10][11][12][13] of Y-stents placed for posttransplant AC have been reported. One study focused on T-tube placement on the right anastomosis and suggested a significant improvement of the FEV1, albeit with a high rate of stent migrations (33%) [14].…”

Bifurcated Silicone Stents for the Management of Anastomotic Complications in Lung Transplanted Patients: Ten Years’ Experience

et al. 2022

Background: In lung transplantation (LT), the actual surgical practice is to cut the donor bronchus as short as possible in order to reduce anastomotic complications (AC). Consequently, the anastomosis is very close to the secondary carina. If AC occur, regular straight stents may be unsatisfactory and on-site modified bifurcated stents may represent an alternative. Objectives: This retrospective study sought to assess the short- and long-term outcomes of patients treated with customized bifurcated stent (CBS) for the management of AC following LT. Methods: Data from patients with AC following LT requiring CBS placement between June 2010 and June 2020 were analyzed. Results: Four hundred patients underwent lung transplant. AC requiring airway stenting occurred in 32 patients (8%), and CBS were inserted in 15 patients (3.5%). Indications were stenosis (n = 12; 80%) and bronchial dehiscence (n = 3; 20%). CBS were successfully deployed in 14 patients and failed in 1 patient. No migration was recorded during the follow-up. The median number of complication was 1 per patient (0–5). CBS could be removed in 11 patients (78.6%), and 3 died with their stents in place. AC recurrence or complications requiring new stenting occurred in 4/11 patients (36.3%), with a median time of 7 days (0–29). Seven patients (63.7%) had no AC recurrence, with a median follow-up of 925 days (118–3,249). Conclusions: The actual surgical anastomotic technique in LT provides new endoscopic challenges. CBS seem ideally positioned to address these difficulties safely and effectively but are associated with stent related complications requiring further endoscopic management.

“…Out of the 76% abnormal bronchoscopic findings, it was observed that most of the pathologies were in the right endobronchial system specifically the right main bronchus. Pathologies in the right endobronchial system and lung are a common finding in literature, especially in the adult population, mainly because of the angulation and length of the right main bronchus [ 2 , 3 ]. The most commonly diagnosed condition in our patients was cancer of the lungs.…”

“…Bronchoscopy has advanced over the past decades from just a diagnostic tool to interventional and endobronchial ultrasound (EBUS) bronchoscopy [ 1 ]. It is a commonly performed procedure by pulmonologists, thoracic surgeons, Ear Nose and Throat (ENT) surgeons and anesthetists for different indications, including but not limited to diagnosis, cancer staging, foreign body removal, airway stenting, dilatation, intubation, management of difficult airway and inhalation injuries [ 2 - 5 ].…”

Introduction the use of flexible bronchoscopy in developing countries is limited. We report our initial experience and outcome with the use of flexible bronchoscopy at the Tamale Teaching Hospital in Ghana. This is the first reported case series of flexible bronchoscopy in Ghana. Methods a retrospective review of patients who had flexible bronchoscopy from 2017-2019 was analyzed. Patient demographics and outcomes were summarized using frequency distribution and percentages. Results we performed flexible bronchoscopies in 33 patients with mean age of 43 years. All patients were symptomatic at the time of presentation with the most common symptoms being chest pain (63.6%), dyspnea (57.6%) and cough (48.5%). The indication for bronchoscopy in most of the cases were suspected malignancy in 16 (48.5%) followed by infection 9 (27.3%), trauma 4 (12.1%) and others 4 (12.1%). We observed abnormal bronchoscopic findings in 25 (75.8%) of the cases with most of the pathologies in the right main bronchus. Twelve patients had toilet bronchoscopy, 6 had biopsy, 5 had no intervention and 4 patients had bronchoalveolar lavage (BAL). Culture and sensitivity results were available for 11 patients, of which 7 patients had negative results. Thirteen (13) malignancies and 11 inflammatory/infectious diseases were diagnosed in this case series. The mean procedure time was 32 minutes with mean hospital stay of 7 days. There was no complication or mortality in our series. Conclusion: flexible bronchoscopy is a safe procedure and indispensable in Ghana where there is an increasing incidence of lung diseases.

“…Different stents (SEMS, silicon, hybrid, and biodegradable stents) have been proposed, but no single method has demonstrated clear superiority and procedure decision mainly depends to single institutions and operators experience. 1,6 Some complex BS even need open surgical approaches. 5 The use of this innovative stenting procedure with a modified endobronchial valve for emphysema, herein presented, appears a suitable option in patients with short segmental and subsegmental BS after LT.…”

Oki stent application in different indications: Six cases

Abstract: Oki stents can safely be used for many clinical conditions. Patients benefit greatly from stenting; however, two of our cases died due to infection, and one case died due to malignancy.
