Abstract: evelopments in the use of prostatic stents Review (3450) Total Article Views Authors: Papatsoris AG, Junaid I, Zachou A, Kachrilas S, Zaman F, Masood J, Buchholz N Published Date April 2011 Volume 2011:3 Pages 63 - 68 DOI: http://dx.doi.org/10.2147/RRU.S11752 Athanasios G Papatsoris, Islam Junaid, Alexandra Zachou, Stefanos Kachrilas, Faruquz Zaman, Junaid Masood, Noor Buchholz Department of Endourology, Barts and the London NHS Trust, London, UK Abstract: Bladder outflow obstruction is a very common age-related clinical entity due to a variety of benign and malignant diseases of the prostate. Surgical treatment under general or regional anesthesia is not suitable for high-risk elderly patients who seek minimally invasive management. Unfortunately, for patients who are not fit for transurethral and/or laser prostatectomy, few treatment options remain, other than long-term catheterization and insertion (under local anesthesia) of a prostatic stent. In this review, we present developments in the use of prostatic stents.
Un-Retrieved Deformed Biodegradable Polymer Coated Drug Eluting Stent after Percutaneous Coronary Intervention to Complete Occluded Right Coronary Artery: Patient at 8 Months Angiographic Follow-Up  [PDF]

International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.55037

Balloon rupture during stent deployment is rare, and can cause stent damage upon its retrieval. We described a case of inadequate drug-eluting stent expansion in a fibrotic and calcified mid right coronary artery lesion despite pre-treatment with high pressure balloon inflation, with rupture and entrapment of the balloon within the stent. Attempts of retrieval of the ruptured balloon caused severe deformity of the distal segment of the stent. The stent could not be crushed or retrieved, and was left in situ. Angiographic follow-up at 8 months time showed widely patent vessel.

Vitalis Obisike Ofuru, Christopher Chinedu Obiorah
International Journal of Clinical Medicine (IJCM) , 2017, DOI: 10.4236/ijcm.2017.811056
Abstract: Background: Dutasteride has been found to reduce chronic prostatic bleeding and when taken 2 - 6 weeks preoperatively reduces bleeding during transurethral prostate resection. The aim of this study is to determine if the drug will be effective in the control of acute gross prostatic haematuria. Patients and Method: 87 Consecutive patients with gross haematuria were enrolled. Clotting Profile, Cystoscopy and Intravenous Urography were done to exclude haematuria from medical, renal and bladder causes. Patients suspected to have prostatic haematuria were further evaluated using serum Prostate specific antigen (PSA) and Prostate scan. Those with elevated PSA ≥ 10 ng/ml and abnormal digital rectal examination (DRE) finding had prostate biopsy. The patients were randomly divided into 2 treatment groups. The control group had Normal saline irrigation and broad spectrum antibiotics while the second group received 0.5 mg oral dutasteride in addition. The time taken and volume of irrigation fluid used before haematuria stopped were noted. Statistical analysis was done using SPSS version 20.0. Result: 75 patients had haematuria of prostatic origin. 49 (65.3%) of these had benign prostatic hyperplasia (BPH) and 26 (34.7%) had cancer of prostate. 25(51%) of the 49 patients with BPH had Normal saline irrigation and antibiotics while 24 (49%) had oral dutasteride in addition. 14 (53.8%) of the prostate cancer patients had Normal saline irrigation and antibiotics while 12 (46.2%) had dutasteride in addition. Haematuria resolved in significantly shorter length of time using lesser volume of irrigation fluid in those treated with dutasteride than in those on control arm. Conclusion: Addition of 0.5 mg oral dutasteride daily leads to early resolution of acute prostatic haematuria.
Biodegradable stent  [PDF]

Abstract: The bare metal stent (BMS) used in the blood vessel caused the restenosis after the operation due to formation and proliferation of neointimal. Recently, as a method to overcome the problems of BMS, drug eluting stent (DES) is developed and being applied to human body which has drug reducing restenosis applied on the metal surface. DES has the advantage of greatly reducing the restenosis after the operation; however, metal stent remains in the body after the drug is released causing issues such as late thrombosis and restenosis so that currently the attention is increasing for biodegradable materials that reduce restenosis and thrombosis by degrading as a certain amount of time passes after the drug is released by the stent material. In this review, the study trend of biodegradable stent will be explained.

Demirhan Ozkan, Hurkal Tugce, Sener Sibel, Ece Ferah
Open Journal of Respiratory Diseases (OJRD) , 2013, DOI: 10.4236/ojrd.2013.31001

In patients who undergo prolonged endotracheal intubation, tracheostomy is performed to prevent the tracheal and laryngeal trauma which may be caused by the intubation tube. In this report, a patient who was intubated after a cerebrovascular embolism and required a tracheostomy for 6 months due to decannulation problems is presented. The patient subsequently developed a tracheomalacia. A stent was inserted and seen to provide functional support. Upon removal of the stent, the tracheomalacia improved. Although surgical therapy is claimed to provide higher success rate, stenting may also be a viable option for the management of tracheomalacia and improve the quality of life in patients with good general condition.

Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.74028
Abstract: Background: To determine the usefulness of metallic stent in advanced oesophageal malignancies. Methods: In a retrospective study conducted at the Endoscopy Unit of King Abdulaziz University Hospital, patients underwent stent placement, with or without palliative radiotherapy for inoperable esophageal cancer, during the period spanning January 2010 through December 2014. Ethical approval for this study was granted by the King Abdulaziz University Research Ethics Committee. Data were collected from the electronic database of the hospital. All patients underwent OGD before stenting to know site of tumor, length of tumor and degree of stricture. Barium meal and CT scan was also done in some cases to know exact characteristics of tumor. Stent was selected more than 2 cm longer than the length of tumor. Self expanding metallic stents were used in all cases. Confirmation of proper placement of stent was done using fluoroscopy. Complications post stenting were analysed. Results: A total of 15 cases were studied. Males were 53.3% while females were 46.7%. Youngest patient was 39 yr old and eldest was 79 years with mean 64.93 years. Mean height was 159.73 cm and mean weight 54.98 kilogram. Co-morbidities like DM was 20%, DM with HTN was 6.7%, bronchial asthma 13.3% and DM with HTN with IHD and Renal implant in 6.7%. Diagnosis at admission was esophageal squamous cell carcinoma in 33.3%, esophageal adeno-carcinoma in 53.3%, gastric cancer in 6.7%, tracho-esophageal fistula in 6.7%. Stage 3 was 13.3%, and stage 4 was 86.7%. Surgical resection and palliation was done in14.2%, and only palliation was done in 92.9% of cases. SEMS were used in all patients and majority had Niti-S stent placed in 73.3% and Wallflex in 13.3% and Ultraflex in 6.7% and Boston in 6.7% cases. Dysphagia was Indication of stenting in 100% of cases and stricture in 57.1% and stricture and recurrent aspiration in 42.9%. Post stenting complications were early in 20% and late in 40%. Tumor ingrowth was in 20%, GERD in 20%, Mild chest pain and discomfort in 10%, stent migration in 10%, fistula formation in 10%, chest pain and GERD in 10%, and aspiration and pneumonia in 20%. Conclusions: Self expanding metallic stents are invaluable in advanced oesophageal cancer for palliation and alleviation of symptoms and better quality of life. Patients prior to chemoradiotherapy may get benefit of stenting making oesophageal passage patent which may otherwise get occluded by edema caused by radiotherapy.

Pharmacology & Pharmacy (PP) , 2011, DOI: 10.4236/pp.2011.24043
Abstract: An 82-year-old male suffered from prostatic cancer five years ago. Since then, he has taken flutamide and was bothered with episodic vertigo (EV) every morning. In order to treat prostatic cancer, flutamide was not discontinued, but conservative treatment and life-style change were recommended. Finally, EV actually subsided. Herein, we report the rare case, in which EV was an unexpected side effect of flutamide. Herein we review his whole history, physical examination, vestibular function test, electronystagmogram, caloric test, awake encephalogram, blood examinations, color-coded duplex ultrasonogram and magnetic resonance imaging/angiogram to suggest a mechanism of flutamide responsible for EV.

Abstract: There are few reported cases in the prostate adenocarcinoma literature with locoregional extension and normal prostate-specific antigen (PSA). We present the case of a patient with prostate adenocarcinoma and metastases with PSA values within the normal range, despite evidence of clinical and radiological progression of the disease. This is a 72-year-old patient presenting with a dysectatic syndrome in which there is a budding ulceration of the glans, an induration of the corpora cavernosa and whose rectal examination has objectified a malignant prostate. PSA was assayed at 3.47 ng/ml; prostatic biopsy and magnetic resonance imaging (MRI) revealed prostate cancer with extension to the urethral, cavernous and rectal areas. Hormone therapy was instituted and the course after two months was marked by the occurrence of several episodes of anemia treated by blood transfusion.

Abstract: Background: Self-expanding metal stents (SEMS) have been used in the management of malignant colorectal obstruction for palliation or as a bridging tool to single-stage surgery. We present the clinical results of a series of patients with colonic cancer in whom SEMS were inserted endoscopically under radiological guidance. Methods: Between September 2007 and January 2010, prospectively collected data from 21 patients who underwent SEMS insertion was analysed. This data includes demographics, indication for stenting, stent size, technical success, clinical success, complications, survival and duration of hospitalisation. Results: 14 male and 7 female patients with malignant colonic obstruction underwent SEMS insertion: 19 requiring palliation and 2 bridging to surgery. The rate of technical success was 100% and of initial clinical success was 100%. In 16/19 (84.2%) of the palliation group, clinical success was maintained at mean follow up of 3.4 months (1-6 months), while 3/19 (15.8%) died, two with functioning stents and one with stent occlusion. The two patients with operable tumours were successfully bridged to one-stage elective surgery at 1 month and 4 months following stenting. Post-procedure complications occurred in 5 patients: 1 perforation, 2 pain, 1 migration and 1 stent occlusion. All patients were discharged alive and the median hospital stay was 1 day (range: 1 to 13 days). Conclusion: SEMS provides an effective and safe option in the palliation of malignant colorectal obstruction. In operable patients, it provides a useful option to avoid colostomy, by facilitating safer single-stage surgery. In this prospective study of SEMS insertion, high rates of technical and initial clinical success were achieved. This could be attributed to performing the procedure under combined endoscopic and radiological guidance.
