Early precut fistulotomy for biliary access : time to change the paradigm of "t...

Lopes, Luís; Ribeiro, Mário Dinis; Rolanda, Carla

Prova tipográfica ; The precut timing during the biliary cannulation algorithm is a subject of controversy. Some studies suggest that early institution of precut is a safe and effective strategy even though the extent to which this approach may affect the duration of the ERCP is seldom addressed. OBJECTIVE: To assess the success, safety, and procedure duration of an early precut fistulotomy (group A) versus a ...


Oncological outcomes after endoscopic removal of malignant colorectal polyps

Gonçalves, Bruno; Fontainhas, Vasco; Caetano, Ana Célia; Ferreira, Aníbal; Gonçalves, Raquel; Bastos, Pedro; Rolanda, Carla

Objective: malignant colorectal polyp, defined by submucosally invasive adenocarcinoma, is the earliest form of clinically relevant colorectal cancer (CRC). After endoscopic resection additional surgery may be necessary, although decision criteria remain debatable. The objective of this study was to assess oncologic outcomes in terms of locoregional disease and to identify areas of improvement that may facilita...


Eosinophilic esophagitis-endoscopic distinguishing findings

Caetano, Ana Célia; Gonçalves, Raquel; Rolanda, Carla

Eosinophilic esophagitis (EE) is the most frequent condition found in a group of gastrointestinal disorders called eosinophilic gastrointestinal diseases. The hypothetical pathophysiological mechanism is related to a hypersensitivity reaction. Gastroesophageal reflux disease- like complaints not ameliorated by acid blockade or occasional symptoms of dysphagia or food impaction are likely presentations of EE. Du...


Transvesical route for NOTES urological applications : advances & controversies

Lima, Estêvão Augusto Rodrigues de; Rolanda, Carla; Pinto, Jorge Correia

Natural 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...


Transesophageal pulmonary lobectomy with single transthoracic port assistance :...

Pinto, João Moreira; Ferreira, Aníbal; Miranda, Alice; Rolanda, Carla; Pinto, Jorge Pinto

BACKGROUND AND STUDY AIMS: Thoracoscopic pulmonary lobectomy is being performed in an increasing number of patients. The aims of the current study were to assess natural orifice transluminal endoscopic surgery (NOTES) as an alternative to transthoracic endoscopic surgery, and to test the feasibility of peroral transesophageal right upper pulmonary lobectomy with the assistance of a single transthoracic trocar. ...


Left atrial appendage ligation with single transthoracic port assistance : a st...

Pinto, João Moreira; Ferreira, Aníbal; Miranda, Alice; Rolanda, Carla; Pinto, Jorge Correia

Background: Left atrial appendage (LAA) exclusion is a well-known procedure for the prevention of stroke in high-risk patients with atrial fibrillation and contraindication to long-term oral anticoagulant therapy. Objective: To evaluate a natural orifice transluminal endoscopic surgery (NOTES) approach for LAA ligation. Design: In 4 acute and 6 survival pigs, we performed LAA by using a forward-viewing, single-ch...


Natural orifice transesophageal endoscopic surgery : state of the art

Pinto, João Moreira; Ferreira, Aníbal; Rolanda, Carla; Pinto, Jorge Correia

The main goal of Natural Orifice Transluminal Endoscopic Surgery (NOTES) is performing surgery avoiding skin incisions. Theoretical advantages of NOTES include decreased postoperative pain, reduction/elimination of general anesthesia, improved cosmetic outcomes, elimination of skin incision-related complications such as wound infections and hernias, and increased overall patient satisfaction. Although various f...


Natural orifice transluminal endoscopy surgery : a review

Pinto, João Moreira; Lima, Estêvão Augusto Rodrigues de; Pinto, Jorge Correia; Rolanda, Carla

Minimally 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...


Peroral esophageal segmentectomy and anastomosis with single transthoracic troc...

Branco, Carlos Filipe do Vale; Rolanda, Carla; Pinto, Jorge Correia; Silva, D.; Moreira, I.; Macedo, G.

BACKGROUND AND STUDY AIMS: A transesophageal natural orifice transluminal endoscopic surgery (NOTES) approach has been proposed for thoracic and mediastinal access. Similarly to transgastric surgery, serious limitations remain related to creating an esophagotomy and its safe closure. A hybrid approach in thoracic NOTES could work as an intermediate step before pure transesophageal NOTES. We assessed the benefit...
