PURPOSE To evaluate the effects of pneumoperitoneum with carbon dioxide and helium on renal function and morphology in a rat model. METHODS Twenty four rats were randomized into three groups (n=8): gasless insufflation ('open', Pressure=0 mmHg), carbon dioxide pneumoperitoneum at 12 mmHg, and helium pneumoperitoneum at 12 mmHg; all lasting 90 minutes.. A cystostomy was performed and the bladd...

BACKGROUND/AIM The aim of this study was to quantify the changes in middle ear pressure (MEP) during robot-assisted radical prostatectomy (RARP). MATERIALS AND METHODS Thirty patients undergoing RARP were included in this study. MEP was obtained at the following time points: awake (T1), postintubation (T2), pneumoperitoneum + 1 h of Trendelenburg position (T3), pneumoperitoneum + 2 h of Trend...

Background: Knowledge of the pathophysiological basis of laparoscopic procedures, in particular the impact of CO2pneumoperitoneum (PNP) on the body, can prevent onset of complications during laparoscopy. Design and Methods: Standard intra-abdominal pressure (IAP), which is used during laparoscopic surgery, is 12 to 15 mm Hg. The direct effect of CO2-pneumoperitoneum is a consequence of the mech...

BACKGROUND/AIM Venous stasis during pneumoperitoneum in laparoscopic surgery is closely related to fibrin synthesis and deposition. The etiologic factors underlying fibrinolysis or hypercoagulability are not clearly defined. This study aimed to determine the effects of pneumoperitoneum time and pressure on coagulation cascade and the fibrinolytic pathway. MATERIALS AND METHODS After the pneum...

BACKGROUND Pneumoperitoneum is a rare cause of abdominal pain characterized by a high mortality. Ultrasonography (US) can detect free intraperitoneal air; however, its accuracy remains unclear. The aims of this pilot study were to define the diagnostic performance and the reliability of abdominal US for the diagnosis of pneumoperitoneum. METHODS This was a prospective observational study. Fou...

BACKGROUND The effects of surgical pneumoperitoneum on lower-limb venous hemodynamics have already been studied; however, the effects of intermittent compression boots are not known in such venous-stasis conditions. METHODS In 12 volunteers and 12 patients, the venous hemodynamic effects of intermittent leg compression were studied under external abdominal pressure or during laparoscopic chol...

PURPOSE In this study, we aimed to review the clinical presentation of preterm infants with gastrointestinal perforations and compare the clinical features of gastric perforation with other intestinal perforations. METHODS The medical records of preterm neonates with pneumoperitoneum, admitted to the neonatal intensive care unit (NICU) between January 1994 and December 2013, were retrospectiv...

BACKGROUND Intra-abdominal hypertension [IAH] occurs frequently among critically ill patients and is associated with increased mortality and organ failure. Two porcine models of IAH that cause abdominal compartment syndrome [ACS] with organ dysfunction were created. We investigated whether the two methods used to create IAH - CO2 pneumoperitoneum or adding volume to the intra-abdominal space - ...
