Randomized Controlled Trial Clinical Trial
A randomized controlled trial assessing the benefit of humidified insufflation gas during laparoscopic surgery.
We conducted a randomized controlled trial during laparoscopic cholecystectomy to determine the extent of heat preservation and postoperative pain reduction using humidified carbon dioxide (CO2) gas insufflation instead of standard dry insufflation gas. ⋯ The use of humidified insufflation gas reduces postoperative pain following laparoscopic cholecystectomy, but except for these relatively brief procedures, the heat-preserving effect of humidified gas insufflation is not significant.

Bile duct clearance at open cholecystectomy had become normal surgical practice before the introduction of laparoscopic cholecystectomy. However, perceived technical difficulties have deterred many surgeons from treating common bile duct stones at the time of laparoscopic cholecystectomy. This has led to a reliance on preoperative clearance of ducts known to have stones and postoperative clearance of ducts found to have stones at operation or those that subsequently develop complications of retained stones. ⋯ We believe that for surgeons familiar with open common bile duct exploration and laparoscopic cholecystectomy, the next logical step is laparoscopic exploration of the common bile duct at the time of cholecystectomy, which is safe and readily mastered.

Comparative Study
Morbidity in laparoscopic gynecological surgery: results of a prospective single-center study.
We set out to investigate prospectively the morbidity rate for gynecological laparoscopy patients at a tertiary care center. ⋯ In our experience, operative gynecological laparoscopy is associated with an acceptable morbidity rate. Moreover, about half of the complications occur during the installation of the laparoscopic procedure, underscoring the usefulness of safety rules.

Concern has been expressed regarding the increased rates of biliary tract injury (BTI) at laparoscopic cholecystectomy. The aim of the present investigation was to analyze the outcome of laparoscopic biliary tract injury with leakage. ⋯ Laparoscopic BTI has a high morbidity and mortality rate that seems comparable to BTI at open cholecystectomy. The number of attempts to repair the BTI as well as additional interventions is too high, but in this patient series the final outcome seemed to be similar after BTI recognized during and after laparoscopic cholecystectomy.

Clinical Trial
Femoral venous flow dynamics during intraperitoneal and preperitoneal laparoscopic insufflation.
Laparoscopic herniorrhaphy may be performed using an intraperitoneal or a preperitoneal approach. Anecdotal and experimental evidence indicates that alterations in lower extremity venous flow, which occur during intraperitoneal laparoscopic insufflation, may be associated with an increased risk of deep vein thrombosis. However, no study has directly compared femoral venous flow during intraperitoneal insufflation with that during preperitoneal insufflation. ⋯ Flow in the common femoral vein is significantly reduced during intraperitoneal insufflation. However, flow in the common femoral vein is not affected by preperitoneal insufflation. These data suggest that laparoscopic preperitoneal inguinal hernia repair may pose as less a risk of thromboembolic complications than laparoscopic intraperitoneal inguinal hernia repair.
