Randomized Controlled Trial
Heating of carbon dioxide during insufflation alters the peritoneal fibrinolytic response to laparoscopic surgery : A clinical trial.
Laparoscopic surgery is evolving rapidly. It involves the creation of a pneumoperitoneum, mostly using carbon dioxide. Cooling of the peritoneum, due to insufflation, might traumatize the peritoneum and disturb peritoneal fibrinolysis, important in peritoneal healing processes. The current study was performed to elucidate the effects of the temperature of insufflation gas on the peritoneal fibrinolytic response to laparoscopic surgery. ⋯ The temperature of carbon dioxide used for insufflation of the abdominal cavity affects peritoneal biology. Cooling of the peritoneum by unheated carbon dioxide causes increased peritoneal PAI-1 levels, important in peritoneal healing processes.

Blunt and penetrating chest traumas continue to be associated with a high mortality rate. The related morbidity rate is a also cause for concern because it may result in extended hospitalization and permanent disabilities. The aim of this study was to retrospectively review a series of consecutive patients treated for chest trauma between 1 January 2000 and 31 December 2005, focusing particularly on cases of pneumothorax and hemothorax. alone or in combination, and to critically assess the treatment protocol adopted. ⋯ In light of their own experience and of reports in the literature confirming both the diagnostic and therapeutic efficacies of VATS in chest trauma with pneumothorax and/or hemothorax, the authors propose a treatment protocol prescribing its use 48 h from the traumatic event in all cases of uncontrolled air and/or blood loss. This protocol yielded excellent results, including an uneventful postoperative course, rapid resolution of the signs and symptoms of the chest problem, and no disabling sequelae (empyema and fibrothorax), as well as a relatively shorter hospital stay and hence lower costs than with conservative treatment.

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.

Comparative Study
The importance of haptic feedback in laparoscopic suturing training and the additive value of virtual reality simulation.
Previous studies on the difference between physical, augmented and virtual reality (VR) simulation state that haptic feedback is an important feature in laparoscopic suturing simulation. Objective assessment is important to improve skills during training. This study focuses on the additive value of VR simulation for laparoscopic suturing training. ⋯ From this study we can conclude that VR simulation does not have a significant additional value in laparoscopic suturing training, over traditional box trainers. One should consider that the future development in VR simulation should focus on basic skills and component tasks of procedural training in laparoscopic surgery, rather than laparoscopic suturing.

Comparative Study
Minimally invasive esophagectomy for cancer: laparoscopic transhiatal procedure or thoracoscopy in prone position followed by laparoscopy?
Minimally invasive esophagectomy is rapidly emerging as a suitable surgical alternative to the open technique. This retrospective comparative study aimed to compare two minimally invasive techniques for esophagectomy: transhiatal laparoscopy with intrathoracic or cervical anastomosis (group A) and right thoracoscopy in prone position followed by laparoscopy and left cervicotomy (group B) performed by the same surgeon (G.B.C.). The operative time, perioperative blood loss, intensive care and total hospital stays, peri- and postoperative morbidity, in-hospital mortality, number of lymph nodes dissected, and survival were the outcome measures. ⋯ This retrospective comparative study showed that minimally invasive esophagectomy performed by thoracoscopy in the prone position is comparable with laparoscopic transhiatal esophagectomy in terms of the significant postoperative and survival outcomes.
