25. Serum cystatin C is a sensitive early marker for changes in the glomerular filtration rate in patients undergoing laparoscopic surgery
OBJECTIVE:Pneumoperitoneum during laparoscopy results in transient oliguria and decreased glomerular filtration and renal blood flow. The presence of oliguria and elevated serum creatinine is suggestive of acute renal injury. Serum cystatin C has been described as a new marker for the detection of this type of injury. In this study, our aim was to compare th

26. Effects of cholecystectomy on the changes of motility of Beagle dogs' sphincter of Oddi
PURPOSE: To observe the effect of cholecystectomy on the changes of motion pattern of Beagle dogs' sphincter of Oddi (SO), and investigate the modulatory role of nitric oxide (NO) and cholecystokinin (CCK) in the regulation of SO.METHODS: Pressure of common bile duct, SO motility, response to bolus injections of cholecystokinin (CCK, 20 ng/kg and 100 ng/kg),

27. Transumbilical endoscopic cholecystectomy in a porcine model
PURPOSE: Natural orifice transluminal endoscopic surgery (NOTES) is a new technique. This study describes our initial experience of NOTES and investigates the feasibility of transumbilical endoscopic cholecystectomy (TUEC). METHODS: Eight domestic pigs were submitted to TUEC. After establishment of pneumoperitoneum, a bi-channel endoscope was placed through

28. Intraoperative cholangiography during elective laparoscopic cholecystectomy: selective or routine use?
PURPOSE: To investigate clinical, laboratory and ultrasonographic parameters in patients with and without preoperative criteria for intraoperative cholangiography (IOC) during laparoscopic cholecystectomy in order to define predictive factors of choledocolithiasis. METHODS: As a criterion for inclusion in the study the patients should present chronic calculo

29. Efeitos da abreviação do jejum pré-operatório com carboidratos e glutamina na resposta metabólica de pacientes submetidos à colecistectomia videolaparoscópica. Estudo controlado randomizado duplo cego / The effects of the abbreviation of preoperative fasting with carbohydrate and glutamine on the metabolic response after videolaparoscopic cholecystectomy. A double blind randomized trial
Introdução: O jejum prolongado pré-operatório aumenta a resistência periférica à insulina. Foi investigado se a abreviação do jejum pré-operatório com uma bebida contendo carboidrato e glutamina melhora a resposta orgânica ao trauma cirúrgico. Métodos: Quarenta e oito pacientes adultas, do sexo feminino (19-62 anos) candidatas a colecistectomia

30. What necessitates the conversion to open cholecystectomy? A retrospective analysis of 5164 consecutive laparoscopic operations
OBJECTIVE: Laparoscopic cholecystectomy (LC) has become the gold standard for the surgical treatment of gallbladder disease, but conversion to open cholecystectomy is still inevitable in certain cases. Knowledge of the rate and impact of the underlying reasons for conversion could help surgeons during preoperative assessment and improve the informed consent

31. O valor da biópsia do fígado na doença hepática gordurosa não alcoólica em pacientes com colelitíase submetidos à colecistectomia laparoscópica / The importance of liver biopsy in non-alcoholic fatty liver disease in patients with cholelithiasis submitted to laparoscopic cholecystectomy
A colelitíase é uma doença frequente na população geral. Um dos seus fatores de risco é a diabetes melitus tipo 2, relacionada à anormalidades metabólicas associadas a sobrepeso, obesidade, resistência à insulina, hipertrigliceridemia e hábitos dietéticos. Fatores de risco semelhantes são encontrados na doença hepática gordurosa não alcoólic

32. Total oxidant status, total antioxidant status, and paraoxonase and arylesterase activities during laparoscopic cholecystectomy
INTRODUCTION: Laparoscopic cholecystectomy is the gold standard for the treatment of gallstone disease; however, adverse hemodynamic changes induced by increased intraabdominal pressure due to pneumoperitoneum are known to occur. Herein, we investigated the effects of pneumoperitoneum on oxidative stress markers, including paraoxonase, arylesterase, total ox

36. Are histological alterations observed in the gallbladder precancerous lesions?
INTRODUCTION: Gallbladder cancer, which is characterized by rapid progression and a poor prognosis, is a complex disease to treat. Unfortunately, little is known currently about its etiology or pathogenesis. A better understanding of its carcinogenesis and determining risk factors that lead to its development could help improve the available treatment option
