Comparative Study
Is a barium swallow complementary to endoscopy essential in the preoperative assessment of laparoscopic antireflux and hiatal hernia surgery?
Barium swallow is considered essential in the preoperative assessment of gastroesophaeal reflux disease and hiatal hernias. The objective of this study was to investigate the effective value of a barium swallow if complementary to the commonly recommended endoscopy before laparoscopic antireflux and hiatal hernia surgery. ⋯ Although barium swallow is recommended as an important diagnostic tool in the workup before surgical antireflux and hiatal hernia therapy, our results suggest that if mandatory endoscopy is performed preoperatively, a barium swallow does not provide any further essential information. It seems that barium swallow can be omitted as a basic diagnostic test before primary laparoscopic antireflux and hiatal hernia surgery.

Review Meta Analysis
Laparoscopic cholecystectomy for severe acute cholecystitis. A meta-analysis of results.
The aim of this review was to evaluate surgical outcomes of laparoscopic cholecystectomy for gangrenous and empyematous acute cholecystitis defined as severe acute cholecystitis. ⋯ A lower feasibility of laparoscopic cholecystectomy has been found for severe cholecystitis. A lower threshold of conversion is recommended since this may allow to reduce local postoperative complications. Literature data lack valuable comparative studies with other treatment modalities, which therefore need to be investigated.

Randomized Controlled Trial
Laparoscopic cholecystectomy with carbon dioxide pneumoperitoneum is safe even for high-risk patients.
Because of absorbed carbon dioxide (CO(2)) and elevated intraabdominal pressure (IAP), CO(2) pneumoperitoneum (CO(2)PP) has potentially harmful intraoperative circulatory and ventilatory effects. Although not clinically significant for healthy patients, these effects are assumed to be deleterious for patients with a high risk for anesthesia (American Society of Anesthesiology [ASA] 3 and 4) and significant cardiopulmonary, renal, or hepatic diseases. The authors assessed CO(2)PP-related adverse effects by comparing ASA 3 and 4 patients who underwent laparoscopic cholecystectomy (LC) with or without CO(2)PP. ⋯ For LC for patients with an ASA 3 and 4 risk for anesthesia, no significant adverse effects could be attributed to CO(2 )pneumoperitoneum. For high-risk patients, preoperative preparation and active perioperative monitoring are essential for safe anesthesia for LC with or without CO(2)PP.

Randomized Controlled Trial Comparative Study
Comparison of three perioperative fluid regimes for laparoscopic donor nephrectomy : A prospective randomized dose-finding study.
Pneumoperitoneum (PP), as used for laparoscopic procedures, impairs stroke volume, renal blood flow, glomerular filtration rate and urine output. This study investigated whether perioperative fluid management can abolish these negative effects of PP on hemodynamics. ⋯ Overnight infusion and a bolus of colloid just before PP attenuate hemodynamic compromise from PP.

Comparative Study
The influence of non-technical performance on technical outcome in laparoscopic cholecystectomy.
Evidence from other professions suggests that training in teamwork and general cognitive abilities, collectively described as non-technical skills, may reduce accidents and errors. The relationship between non-technical teamwork skills and technical errors was studied using a behavioural marker system validated in aviation and adapted for use in surgery. ⋯ Non-technical skills are an important component of surgical skill, particularly in relation to the development and maintenance of a surgeon's situational awareness. Experience from other industries suggests that it may be possible to improve the ability of surgeons to manage their own situation awareness, through training, intraoperative briefings and intraoperative workload management. In the future, it may be possible to use non-technical performance as a surrogate measure for technical performance, either for early identification of surgical difficulties, or as a method of evaluation by which non-surgically trained observers.
