OBJECTIVES: Video laparoscopic bariatric surgery is the preferred surgical technique for treating morbid obesity. However, pneumoperitoneum can pose risks to the kidneys by causing a decrease in renal blood flow. Furthermore, as in other surgical procedures, laparoscopic bariatric surgery triggers an acute inflammatory response. Neutrophil gelatinase-associated lipocalin is an early and accurate biomarker of renal injury, as well as of the inflammatory response. Anesthetic drugs could offer some protection for the kidneys and could attenuate the acute inflammatory response from surgical trauma. The objective of this study was to compare the effects of two types of anesthetics, propofol and sevoflurane, on the serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in laparoscopic bariatric surgery. METHODS: Sixty-four patients scheduled for laparoscopic bariatric surgery were randomized into two anesthesia groups and were administered either total intravenous anesthesia (propofol) or inhalation anesthesia (sevoflurane). In the perioperative period, blood samples were collected at three time points (before anesthesia, 6 hours after pneumoperitoneum and 24 hours after pneumoperitoneum) and urine output was measured for 24 hours. Acute kidney injuries were evaluated by examining both the clinical and laboratory parameters during the postoperative period. The differences between the groups were compared using non-parametric tests. ReBEC (http://www.ensaiosclinicos.gov.br/rg/recruiting/): RBR-8wt2fy RESULTS: None of the patients developed an acute kidney injury during the study and no significant differences were found between the serum neutrophil gelatinase-associated lipocalin levels of the groups during the perioperative period. CONCLUSION: The choice of anesthetic drug, either propofol or sevoflurane, did not affect the serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in laparoscopic bariatric surgery.

Natural orifice transluminal endoscopic surgery (NOTES) is an emerging experimental alternative to conventional surgery that eliminates abdominal incisions and incision-related complications by combining endoscopic and laparoscopic techniques to diagnose and treat abdominal pathology. Natural orifice transluminal endoscopic surgery refers to the method of accessing the abdominal cavity through a natural orifice under endoscopic visualization. Since its introduction in 2004, numerous reports have been published describing different surgical interventions. Recently, a group of expert laparoscopic surgeons and endoscopists outlined the limitations of this approach and issued recommendations for progress toward human trials. Transluminal surgery is a new method for accessing the abdomen under direct endoscopic visualization. Preliminary studies have demonstrated the feasibility of this technique in animal models; however, further research is warranted to validate its safety in humans.

RACIONAL: Herniorrafia inguinal, um procedimento cirúrgico comum no mundo todo, representa um importante gasto para saúde pública. Variadas abordagens cirúrgicas e opções de procedimentos anestésicos estão disponíveis para o reparo das hérnias inguinais atualmente. O objetivo do presente trabalho consiste em revisar e avaliar o tratamento cirúrgico inguinal pela técnica de Lichtenstein sob anestesia local. MÉTODOS: Dados de pesquisa constituíram-se de artigos científicos publicados e disponibilizados no site do PubMed (www.pubmed.gov). A revisão de literatura baseou-se no cruzamento dos seguintes descritores: herniorrafia inguinal, anestesia local e técnica de Lichtenstein. Cento e oito publicações relacionadas ao tema foram revisadas. CONCLUSÕES: A combinação entre anestesia local e o emprego da técnica livre de tensão de Lichtenstein para o reparo de hérnia inguinal primária demonstrou resultados positivos. A associação descrita mostrou reduções significativas na recorrência de hérnia inguinal e nas complicações pós-operatórias, assim como diminuição da dor crônica eventualmente presente em uma avaliação tardia. O melhor controle da dor pós-operatória imediata, a alta hospitalar precoce e o retorno às atividades laborativas podem ser atribuídos de maneira direta ou indireta às técnicas empregadas, refletindo na satisfação do paciente e em baixos custos para saúde pública.

BACKGROUND: Inguinal herniorrhaphy, a common surgical procedure performed worldwide, represents an important expense for public health. A variety of surgical approaches and options for anesthesical procedures are available nowadays for inguinal hernia repair. The aim of this study is to review and to evaluate the Lichtenstein inguinal surgical treatment under local anesthesia. METHODS: Researching data consisted of scientific articles published and available at PubMed site (www.pubmed.gov). Literature review based on crossing the following headings: inguinal herniorrhaphy, local anesthesia and Lichtenstein technique. One hundred and eight publications related to the subject were reviewed. CONCLUSION: Combination between local anesthesia and tension-free Lichtenstein technique for primary inguinal hernia repair demonstrates positive results. The association described shows a significantly decrease in inguinal hernia recurrence and in postoperative complications, as well as reducing chronic pain that might be present in a late follow-up. The better immediate postoperative pain control, early hospital patient discharge and a faster return to job activities may all be attributed directly or indirectly to the technique implemented, reflecting increased patient satisfaction and lower costs for public health.
