Colecistectomia Videolaparoscópica Transumbilical Single Site com Equipamento de Laparoscopia Convencional - Rolanda, C
artigo 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.

Natural orifice transesophageal endoscopic surgery: state of the art - Moreira-Pinto, J; Ferreira, A; Rolanda, C; Correia-Pinto, J
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 forms of port creation to accomplish thoracic NOTES procedures have been proposed, transesophageal NOTES has been shown to be the most reliable one. The evolution of endoscopic submucosal transesophageal access resulted in the development of per-oral endoscopic myotomy (POEM), which had a fast transition to clinical practice. The authors present a...

Transvesical thoracoscopy: A natural orifice translumenal endoscopic approach for thoracic surgery - Lima, E; Henriques-Coelho, T; Rolanda, C; Pego, JM; Silva, D; Carvalho, JL; Correia-Pinto, J
Background
Recently there has been an increasing enthusiasm for using natural orifices translumenal endoscopic surgery (NOTES) to perform scarless abdominal procedures. We have previously reported the feasibility and safety of the transvesical endoscopic peritoneoscopy in a long-term survival porcine model as useful for those purposes. Herein, we report our successful experience performing transvesical and transdiaphragmatic endoscopic approach to the thoracic cavity in a long-term survival study in a porcine model.
Methods
Transvesical and transdiaphragmatic endoscopic thoracoscopy was performed in six anesthetized female pigs. A 5 mm transvesical port was created on the bladder wall and an ureteroscope was advanced into the peritoneal cavity....

A novel de novo deletion of chromosome 7 [46,XX,del(7)(p14.2 p15.1)] in a child with feeding problems - Antunes, H; Gonçalves, JP; Silva, E; Teles, N
The phenotype and severity of symptoms associated with deletions on chromosome 7 are directly proportional to the size of the deleted segment. Distal and interstitial deletions have been described in 40 cases. In this report the authors aim to report a child with a novel de novo interstitial deletion on chromosome 7, with the following karyotype: 46,XX,del(7)(p14.2 p15.1). We described a female, born at 38 weeks with intrauterine growth restriction and feeding problems with episodes of cyanosis after feedings and failure to thrive. Physical examination showed low implantation of ears, hypertelorism, oblique palpebral fissures, retrognathia, and palate ogived, with insertion...

Eosinophilic esophagitis-endoscopic distinguishing findings - Caetano, AC; Gonçalves, R; Rolanda, C
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. 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...

Primeira determinação de prevalência de doença celíaca numa população portuguesa - Antunes, H; Abreu, I; Nogueira, A; Sá, C; Gonçalves, C; Cleto, P; Garcia, F; Alves, A; Lemos, D
The prevalence of celiac disease is unknown in Portugal. In European countries the prevalence is between 1:200 and 1:400. The incidence obtained through diagnosed cases in the paediatric gastroenterology units in Portugal was 1:3648. To determine the best current celiac disease screening method and its prevalence in a portuguese population, 536 sera of teenagers with 14 years +/- 6 months from Braga town schools were tested as follows: a) total IgA, b) anti-tissue transglutaminase antibodies c) anti-endomysium antibodies (AEA). One female adolescent, with negative AEA and anti-transglutaminase antibodies had a diagnosed celiac disease; this patient was under appropriate diet. Eleven...

Serum leptin levels in overweight children and adolescents - Antunes, H; Santos, C; Carvalho, S
Leptin is an adipocyte-secreted hormone which plays a key role in energy homeostasis. Our aim was to determine the relationship between serum leptin and clinical and biochemical features in overweight children and adolescents. Overweight children and adolescents followed in this Unit with serum leptin ascertained were included. Clinical, biochemical and abdominal ultrasound data were analysed. Statistical analysis was performed by t test, chi2, Pearson's correlation and linear regression. One outlier of serum leptin was excluded to perform correlation and regression. Serum leptin was determined in 357 patients. At the first visit, the mean age was 9.5 (sd 3.2) years and...

G2P[4] the most prevalent rotavirus genotype in 2007 winter season in an European non-vaccinated population - Antunes, H; Afonso, A; Iturriza, M; Martinho, I; Ribeiro, C; Rocha, S; Magalhães, C; Carvalho, L; Branca, F; Gray, J
BACKGROUND:
Recently, a high prevalence of G2P[4] rotavirus (RV) infection was reported from Brazil, and linked with the universal RV vaccination programme that used the G1P[8] live oral RV vaccine.
OBJECTIVE:
To determine the genotypes of RV co-circulating in a non-vaccinated population, in northern Portugal in the winter season of 2007.
STUDY DESIGN:
Prospective multicenter study of the genotypes circulating in the northwest region of Portugal during January to March 2007. Children with acute gastroenteritis, who attended the Pediatric Emergency Services of five Hospitals, were included in the study. The parents of the children completed a clinical and epidemiological data questionnaire and stool samples were...

Third-generation nephrectomy by natural orifice transluminal endoscopic surgery - Lima, E; Rolanda, C; Pêgo, JM; Henriques-Coelho, T; Silva, D; Osório, L; Moreira, I; Carvalho, JL; Correia-Pinto, J
PURPOSE:
Recently there has been increasing enthusiasm for performing simple abdominal procedures by transgastric surgery. We previously reported the usefulness of a combined transgastric and transvesical approach to cholecystectomy. In this study we assessed the feasibility of combined transgastric and transvesical approach for performing a more complex surgical procedure, such as nephrectomy, in a porcine model.
MATERIALS AND METHODS:
In a nonsurvival study combined transgastric and transvesical approaches were established in 6 female pigs. Under ureteroscope guidance we installed a transvesical 5 mm over tube into the peritoneal cavity and a flexible gastroscope was passed orally into the peritoneal cavity by a gastrotomy....

Endoscopic closure of transmural bladder wall perforations - 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, J
BACKGROUND:
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...
