Post-surgical atypical mycobacteriosis in 125 patients in Rio de Janeiro

Abstract INTRODUCTION: The growing incidence of post-surgical atypical mycobacteriosis (PSAM) may be related to the increased use of low- and medium-complexity video-assisted surgery. METHODS: Between April 2007 and June 2009, 125 patients were referred from the State Health Department of Rio de Janeiro for the treatment of confirmed, probable, or suspected PSAM. RESULTS: Laparoscopic cholecystectomy was the most frequent surgical procedure (48.8%) among patients. Clarithromycin, ethambutol, and terizidone were used to treat 113 patients for a mean duration of 226 days. CONCLUSIONS: Despite the need for multidrug therapy and long treatment duration, most included patients adhered to treatment and experienced cure without relapse.

General anesthesia type does not influence serum levels of neutrophil gelatinase-associated lipocalin during the perioperative period in video laparoscopic bariatric surgery

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 ...

Prognóstico da videocirurgia da região frontal com técnica modificada de fixação / Prognosis of frontal region video surgery with a modified fixation technique

INTRODUÇÃO: A videoendoscopia tem se estabelecido como procedimento de escolha no tratamento da ptose do supercílio e das rugas da região frontal. O acesso minimamente invasivo produz vantagens em relação à tradicional incisão coronal. Diversos métodos de fixação são relatados na literatura, apresentando resultados semelhantes. Nesta série de casos, descrevemos a fixação direta com agulha. OBJETIVO: Avaliar o prognóstico da videocirurgia, utilizando-se a técnica direta com agulha. MÉTODO: Avaliação fotográfica computadorizada de 37 pacientes submetidos à videoendoscopia da região frontal com a fixação direta com agulha, realizada em dois hospitais privados na cidade de Porto Alegre-RS. Resultados: A elevação média do supercílio foi de 5,7 mm no terço lateral e de 4,4 mm no terço medial. Após um pequeno descenso da elevação, no primeiro mês pós-operatório, o reposicionamento do supercílio permaneceu inalterado nas medidas subsequentes até 24 meses. CONCLUSÃO: A fixação direta com agulha é capaz de produzir resultados duráveis, seguros e reprodutíveis no período em que foram realizadas as medições.

INTRODUCTION: Video endoscopy has become a procedure of choice for the treatment of eyebrow ptosis and forehead wrinkles. This minimally invasive technique has several advantages over traditional coronal incision. Several fixation methods are reported in the literature, with similar results. In this study, we describe direct needle fixation. OBJECTIVE: To evaluate the prognosis of video endoscopic surgery using a direct needle technique. METHOD: Computerized photographic evaluations of 37 patients undergoing video endoscopy of the frontal region with needle direct fixation were conducted in two private hospitals in the city of Porto Alegre in Rio Grande do Sul, Brazil. RESULTS: The mean eyebrow elevations were 5.7 and 4.4 mm in the lateral and middle third measurements. After a small dip in elevation in the first month after surgery, the repositioning of the eyebrow remained unchanged in subsequent measurements up to 24 months later. CONCLUSION: Direct needle fixation produced lasting, reliable, and reproducible results during the period in which measurements were made.

Experimental model of the formation of pelvic adhesions by videolaparoscopic in female rabbits / Modelo experimental de formação de aderências pélvicas por videolaparoscopia em coelhas

PURPOSE: To verify the frequency of postsurgical pelvic adhesion formation in an experimental animal model using videolaparoscopy. METHODS: Experimental study in a sample of 11 non-pregnant female rabbits, aged 5 to 7 months. After general anesthesia, access to the abdominal cavity was performed by an open puncture technique, with 10mm optics, placing two other 5 mm trochars under direct visualization, in the iliac fossae. Then a fragment of peritoneum was resected, followed by electrocauterization. In 21 days, the videolaparoscopy was repeated, and adhesion formation and score was looked at, with biopsies at the surgical site. RESULTS: 54 percent of adhesion formation was observed, and the median score of adhesions was 6 (minimum of 3 and maximum of 10), all of them found in the bladder and the anterior abdominal wall. CONCLUSION: The method used presents a high frequency of intra-abdominal adhesion formation.

OBJETIVO: Verificar a freqüência da formação de aderências pélvicas pós-cirúrgicas, em um modelo experimental animal, por videolaparoscopia. MÉTODOS: Estudo experimental, em uma amostra de 11 coelhas, não prenhas, com idade entre cinco e sete meses. Após anestesia geral, o acesso da cavidade abdominal foi efetuado por técnica de punção aberta, com óptica de 10 mm, colocando-se outros dois trocateres de 5 mm, sob visão direta, nas fossas ilíacas. Realizou-se, então, ressecção de fragmento de peritônio, seguida de cauterização com eletrocautério. Em 21 dias, foi repetida a videolaparoscopia, verificando-se a formação e escore de aderências e realizando-se biópsias do local da cirurgia. RESULTADOS: Observou-se 54,5 por cento de formação de aderências, sendo o escore total mediano de aderências seis (mínimo de três e máximo de 10), todas encontradas na bexiga e na parede abdominal anterior. CONCLUSÃO: O procedimento utilizado apresentou alta freqüência de formação de aderências intra-abdominais.

Incisional hernia at the insertion site of the laparoscopic trocar: case report and review of the literature

Laparoscopic operations offer a myriad of advantages resulting in a rapid postoperative recovery. Incisional hernia is an uncommon cause of morbidity in operative procedures performed by laparoscopic access, and the diagnosis may not be easily made. In our service we identified 2 patients with incisional hernia the site of trocar insertion. The records of these 2 cases were reviewed. We report on these 2 cases and present a review of the literature
