A novel method of full-thickness bladder closure with an endoscopic suturing ma...
Oliveira, Carlos; Autorino, Riccardo; Ferreira, Carlos; Cicione, Antonio; Damiano, Rocco; De Sio, Marco; Pinto, Jorge Correia"Accepted article (accepted manuscript online: 21 FEB 2014)" ; Objective To assess the feasibility of a pure endoscopic closure method for vesical perforations using fully absorbable material. Materials and methods A pilot experimental study was performed in 8 anesthetized female pigs. Four 10mm and four 20mm endoscopic full thickness cystotomies were created. An endoscopic suturing machine (RD 180®, LSI solut...
Tailor made degradable ureteral stents from natural origin polysaccharides
Barros, Alexandre A.; Duarte, Ana Rita C.; Pires, R. A.; Lima, Estêvão Augusto Rodrigues de; Mano, J. F.; Reis, R. L.A urinary stent is defined as a thin tube, which is inserted in the ureter to prevent or treat the obstruction of urine flow from the kidney. Silicone, latex, polyvinylchloride and polyurethanes are the most widely used materials for the preparation of stents. Nonetheless, severe clinical complications may result from the use of these materials such as fracture, encrustation and infection. In some of the cases,...
Transvesical route for NOTES urological applications : advances & controversies
Lima, Estêvão Augusto Rodrigues de; Rolanda, Carla; Pinto, Jorge CorreiaNatural Orifice Transluminal Endoscopic Surgery (NOTES) has emerged recently in the experimental surgical field, innovating for the passage of luminal barrier, the absence of scars and reduction of post-operative pain. Among the various ports of access (transvaginal, transgastric, transvesical and transcolonic), this paper is an update on advances & controversies of transvesical port for NOTES Urological applic...
Transvesical natural orifice transluminal endoscopic surgery (NOTES) nephrectom...
Lima, Estêvão Augusto Rodrigues de; Branco, Frederico; Parente, Joana; Autorino, Riccardo; Pinto, Jorge CorreiaThe authorsacknowledge Karl Storz, Richard Wolf and Covidien for their support with equipment. ; What's known on the subject? and What does the study add? Until now, the transvaginal approach has been the only method of removing larger specimens from the abdominal cavity using natural orifi ce transluminal endoscopic surgery. There has been no means of extracting larger specimens in men and the means are restr...
Low-cost reusable instrumentation for laparoendoscopic single-site nephrectomy ...
Autorino, Riccardo; Kim, Fernando J.; Rane, Abhay; De Sio, Marco; Stein, Robert J.; Damiano, Rocco; Micali, Salvatore; Pinto, Jorge CorreiaPurpose: To test different sets of prebent instruments and a new reusable access device for laparoendoscopic single-site (LESS) surgery. Materials and Methods: Three surgeons with previous experience in LESS performed 12 nephrectomies in six pigs. In all procedures, a multichannel access device (X-CONE_) and a 5-mm extra-long telescope were used. Four sets of prebent instruments with different profiles (S-porta...
Natural orifice transluminal endoscopy surgery : a review
Pinto, João Moreira; Lima, Estêvão Augusto Rodrigues de; Pinto, Jorge Correia; Rolanda, CarlaMinimally invasive surgery started spreading worldwide in 1987, when the first laparoscopic cholecystectomy was performed. Meanwhile, improvement of endoscopic equipment and instruments allowed gastroenterologists to attempt more aggressive endoluminal interventions, even beyond the wall barrier. The first transgastric peritoneoscopy, in 2004, brought to light the concept of natural orifice transluminal endosco...
Transvesical endoscopic port in abdominal surgery : an updated perspective
Lima, Estêvão Augusto Rodrigues de; Autorino, Riccardo; Pinto, Jorge CorreiaTransvesical endoscopic port in abdominal surgery: an updated perspective. ; Natural orifice transluminal endoscopic surgery (NOTES) generated a huge hope among surgeons because it promised scarless surgery and eventually less pain and surgical stress. However, serious limitations regarding reliable visceral closing methods remain unsolved. This article provides an update in development and future applications...
Development of transvesical port for scarless surgery
Lima, Estêvão Augusto Rodrigues deTese de Doutoramento em Ciências da Saúde - Área do Conhecimento em Medicina Clínica ; A cirurgia endoscópica transluminal por orifícios naturais (N.O.T.E.S.) é uma área de investigação que está no limiar das novas técnicas cirúrgicas com aplicação em Humanos. Após a descrição do acesso transgástrico, e do seu inesperado sucesso como nova porta para acesso abdominal, duas evidências sobressaíram: i) a qualidad...
