- Colecistectomia Videolaparoscópica Transumbilical Single Site com Equipamento de Laparoscopia ConvencionalPublication . Rolanda, Cartigo intitulado Colecistectomia videolaparoscópica transumbilical (single site) com equipamento de laparoscopia convencional recentemente publicado por Alves Júnior e colaboradores mereceu-nos atenção e algumas considerações que gostaria de partilhar. Embora aborde uma temática tradicionalmente adstrita à Cirurgia Geral, vale a pena revisitar alguns conceitos e perceber o contexto actual da cirurgia minimamente invasiva (MIS), onde também temos lugar enquanto gastrenterologistas.

- Emergencies after endoscopic proceduresPublication . Rolanda, C; Caetano, AC; Dinis-Ribeiro, MEndoscopy adverse events (AEs), or complications, are a rising concern on the quality of endoscopic care, given the technical advances and the crescent complexity of therapeutic procedures, over the entire gastrointestinal and bilio-pancreatic tract. In a small percentage, not established, there can be real emergency conditions, as perforation, severe bleeding, embolization or infection. Distinct variables interfere in its occurrence, although, the awareness of the operator for their potential, early recognition, and local organized facilities for immediate handling, makes all the difference in the subsequent outcome. This review outlines general AEs' frequencies, important predisposing factors and putative prophylactic measures for specific procedures (from conventional endoscopy to endoscopic cholangio-pancreatography and ultrasonography), with comprehensive approaches to the management of emergent bleeding and perforation.
- Endoscopic closure of transmural bladder wall perforationsPublication . Lima, E; Rolanda, C; Osório, L; Pêgo, JM; Silva, D; Henriques-Coelho, T; Carvalho, JL; Bergström, M; Park, PO; Mosse, CA; Swain, P; Correia-Pinto, JBACKGROUND: Traditionally, intraperitoneal bladder perforations caused by trauma or iatrogenic interventions have been treated by open or laparoscopic surgery. Additionally, transvesical access to the peritoneal cavity has been reported to be feasible and useful for natural orifice translumenal endoscopic surgery (NOTES) but would be enhanced by a reliable method of closing the vesicotomy. OBJECTIVE: To assess the feasibility and safety of an endoscopic closure method for vesical perforations using a flexible, small-diameter endoscopic suturing kit in a survival porcine model. DESIGN, SETTING, AND PARTICIPANTS: This pilot study was performed at the University of Minho, Braga, Portugal, using six anesthetized female pigs. INTERVENTIONS: Closure of a full-thickness longitudinal incision in the bladder dome (up to 10 mm in four animals and up to 20 mm in two animals) with the endoscopic suturing kit using one to three absorbable stitches. MEASUREMENTS: The acute quality of sealing was immediately tested by distending the bladder with methylene-blue dye under laparoscopic control (in two animals). Without a bladder catheter, the animals were monitored daily for 2 wk, and a necropsy examination was performed to check for the signs of peritonitis, wound dehiscence, and quality of healing. RESULTS AND LIMITATIONS: Endoscopic closure of bladder perforation was carried out easily and quickly in all animals. The laparoscopic view revealed no acute leak of methylene-blue dye after distension of the bladder. After recovery from anaesthesia, the pigs began to void normally, and no adverse event occurred. Postmortem examination revealed complete healing of vesical incision with no signs of infection or adhesions in the peritoneal cavity. No limitations have yet been studied clinically. CONCLUSIONS: This study demonstrates the feasibility and the safety of endoscopic closure of vesical perforations with an endoscopic suturing kit in a survival porcine model. This study provides support for further studies using endoscopic closure of the bladder which may lead to a new era in management of bladder rupture and adoption of the transvesical port in NOTES procedures.

- Eosinophilic esophagitis-endoscopic distinguishing findingsPublication . Caetano, AC; Gonçalves, R; Rolanda, CEosinophilic 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. Due to its unclear pathogenesis and unspecific symptoms, it is difficult to diagnose EE without a strong suspicion. Although histological criteria are necessary to diagnosis EE, there are some characteristic endoscopic features. We present the case of a healthy 55-year-old woman with dysphagia and several episodes of esophageal food impaction over the last six months. This case report stresses the most distinguishing endoscopic findings-mucosa rings, white exudative plaques and linear furrows-that can help in the prompt recognition of this condition.
- Experimental foundation for natural orifice transluminal endoscopic surgery and hybrid natural orifice transluminal endoscopic surgeryPublication . Lima, E; Rolanda, C; Autorino, R; Correia-Pinto, JNatural orifice transluminal endoscopic surgery (NOTES) is one of the most exciting concepts that has emerged recently in the surgical field. All accesses to the abdominal cavity in the porcine model using natural orifices, e.g. transgastric, transvesical, transcolonic and transvaginal, have been described and explored. The experimental feasibility of all procedures by NOTES was successfully demonstrated in the porcine model using different types of natural orifices. However, few translations to the human have been made. NOTES is in a developmental stage and much work is still needed to refine techniques, verify safety and document efficacy. This paper is an update on the experimental foundation for NOTES and hybrid NOTES and examines the opportunities presented by this new surgical vision.
