Laparoscopic Nissen, Nissen-Rossetti, cardial calibration with gastropexy, and other modifications are the procedures commonly used for surgical treatment of gastroesophageal reflux disease. Postoperative failures have been reported ranging from 10% to 15% associated with postoperative symptoms or recurrent gastroesophageal reflux. In this paper, we present(More)
BACKGROUND Bile leakage is more common after laparoscopic cholecystectomy than after open surgery. In our department, the rate of postoperative bile collections after open surgery is 0.2% vs 0.6% after laparoscopic cholecystectomy. METHODS We studied 13 cases of intraperitoneal bile collection without common bile duct damage drawn from a total of 5,200(More)
PURPOSE To measure the acceleration in multiple directions of the rotational instability in ACL deficient models using porcine knees. METHODS Ten porcine knees were tested with ACL intact and tear models. The pivot shift test was performed manually, and the acceleration of the pivot shift phenomenon was recorded by the use of a triaxial accelerometer.(More)
Controlled generation of reactive oxygen species (ROS) may contribute to physiological intracellular signaling events. We determined ROS generation in primary cultures of rat skeletal muscle after field stimulation (400 1-ms pulses at a frequency of 45 Hz) or after depolarization with 65 mM K+ for 1 min. Both protocols induced a long lasting increase in(More)
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has been introduced as a multipurpose restrictive procedure for obese patients. Variations of the surgical technique may be important for the late results. METHODS 50 patients submitted to LSG from January 2005 to December 2006 were studied. Mean age was 38.2 years, preoperative weight was 103.4 +/- 14.1 kg(More)
Laparoscopic cholecystectomy is currently the standard procedure for chronic and acute cholecystitis. The purpose of this prospective study was to evaluate the preoperative ultrasound findings of the gallbladder and correlate those aspects with surgical videoscopic and histopathologic findings and the results concerning intraoperative complications and the(More)
PURPOSE Different tunnel configurations have been used for double-bundle (DB) anterior cruciate ligament (ACL) reconstruction. However, controversy still exists as to whether three-tunnel DB with double-femoral tunnels and single-tibial tunnel (2F-1T) or with single-femoral tunnel and double-tibial tunnels (1F-2T) better restores intact knee biomechanics(More)
PURPOSE Conventional transtibial technique fails to restore the rotational knee stability in spite of successful anterior laxity, while anatomic anterior cruciate ligament reconstruction using the anteromedial portal technique has been developed expecting better rotational kinematics because of closer reproduction of the native anterior cruciate ligament(More)
The indications for routine intraoperative cholangiography remain controversial. We present here our recent results concerning the frequency of unknown retained common bile duct stones in 253 consecutive patients who underwent laparoscopic cholecystectomy without intraoperative cholangiography in whom the presence of preoperative choledocholithiasis had(More)
Laparoscopic antireflux surgery is the gold standard procedure for treatment of patients with reflux esophagitis. The current results of the laparoscopic approach are absolutely comparables with the results obtained during the open surgery era. The Nissen, Nissen-Rossetti, or Toupet techniques are the more frequently used. We have performed cardial(More)
