Pudendal canal syndrome (PCS) is induced by the compression or the stretching of the pudendal nerve within Alcock's canal. ⋯ Considering that none of the surgical procedures currently used are known to completely improve all the symptoms of PCS, ILPCD could theoretically reduce stretching of the pudendal nerve.

Comparative Study
Construct validity testing of a laparoscopic surgery simulator (Lap Mentor): evaluation of surgical skill with a virtual laparoscopic training simulator.
Before surgical simulators can be implemented for assessment of surgical training, their construct validity should be assessed. ⋯ Performance parameters of the Lap-Mentor can be used to distinguish between subjects with varying laparoscopic experience.

Comparative Study
Liver resection with intraoperative and laparoscopic ultrasound: report of 32 cases : Ultrasonic shears device for liver parenchymal transection.
Careful staging of hepatic tumors is mandatory for appropriate selection of patients for liver resection. Number and relationships of liver nodules are issues of utmost importance when evaluating resectability. Sensitivity of preoperative imaging for secondary lesions has been reported between 60-75% with spiral contrast-enhanced computed cosmography (CT), 80-85% with magnetic resonance imaging (MRI), and 90-96% with intraoperative ultrasound (IOUS). Also for primary lesions IOUS has been reported to allow detection of liver nodules in 17% and modify surgical strategy in 10%. The aim of this study was to point out the usefulness of open (IOUS) and laparoscopic (LIOUS) ultrasound in patients undergoing hepatic surgery for liver tumors. ⋯ In our experience LIUOS and IOUS proved to be of utmost importance both in the selection of patients for resective surgery and in planning surgical approach. Ultrasonic shears device and systematic pedicle clamping sped up resection time and reduced intraoperative bleeding.

Comparative Study
Ultrashort intracorporeally maneuverable cryoprobes for laparoscopic renal cryoablation in the porcine model.
To determine the feasibility and efficacy of laparoscopic renal cryosurgery using a novel ultrathin ultrashort intracorporeal cryoprobe in a porcine model. ⋯ Our novel cryoprobe can be used effectively and conveniently in laparoscopic renal cryosurgery. Considering the size of the cryogenic lesion, using a cluster of probes may be advisable.

Randomized Controlled Trial
Prevention of postoperative nausea and vomiting with a small dose of propofol alone and combined with dexamethasone in patients undergoing laparoscopic cholecystectomy: A prospective, randomized, double-blind study.
A small dose of propofol is directly antiemetic, and is effective for the prevention of postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic cholecystectomy (LC). However, this regimen cannot entirely control PONV after LC. ⋯ Propofol 0.5 mg/kg combined with dexamethasone 8 mg is more effective than propofol alone for the prevention of PONV during the first 24 hours after anesthesia in patients undergoing LC.
