Randomized Controlled Trial Comparative Study
Different pain scores in single transumbilical incision laparoscopic cholecystectomy versus classic laparoscopic cholecystectomy: a randomized controlled trial.
The attempt to further reduce operative trauma in laparoscopic cholecystectomy has led to new techniques such as natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopic surgery (SILS). These new techniques are considered to be painless procedures, but no published studies investigate the possibility of different pain scores in these new techniques versus classic laparoscopic cholecystectomy. In this randomized control study, we investigated pain scores in SILS cholecystectomy versus classic laparoscopic cholecystectomy. ⋯ SILS cholecystectomy, as well as the invisible scar, has significantly lower abdominal and shoulder pain scores, especially after the first 24 h postoperatively, when this pain is nonexistent. (Registration Clinical Trial number: NTC00872287, www.clinicaltrials.gov ).

Multicenter Study
Global Assessment of Gastrointestinal Endoscopic Skills (GAGES): a valid measurement tool for technical skills in flexible endoscopy.
Simulators may improve the efficiency, safety, and quality of endoscopic training. However, no objective, reliable, and valid tool exists to assess clinical endoscopic skills. Such a tool to measure the outcomes of educational strategies is a necessity. This multicenter, multidisciplinary trial aimed to develop instruments for evaluating basic flexible endoscopic skills and to demonstrate their reliability and validity. ⋯ The GAGES-UE and GAGES-C are easy to administer and consistent and meet high standards of reliability and validity. They can be used to measure the effectiveness of simulator training and to provide specific feedback. The GAGES results can be generalized to North American and European endoscopists and may contribute to the definition of technical proficiency in endoscopy.

Awareness of the relative high rate of adverse events in laparoscopic surgery created a need to safeguard quality and safety of performance better. Technological innovations, such as integrated operating room (OR) systems and checklists, have the potential to improve patient safety, OR efficiency, and surgical outcomes. This study was designed to investigate the influence of the integrated OR system and Pro/cheQ, a digital checklist tool, on the number and type of equipment- and instrument-related risk-sensitive events (RSE) during laparoscopic cholecystectomies. ⋯ Using both an integrated OR and Pro/cheQ has a stronger reducing effect on the number of RSE than using an integrated OR alone. The Pro/cheQ tool supported the optimal workflow in a natural way and raised the general safety awareness amongst all members of the surgical team. For tools such as integrated OR systems and checklists to succeed it is pivotal not to underestimate the value of the implementation process. To further improve safety and quality of surgery, a multifaceted approach should be followed, focusing on the performance and competence of the surgical team as a whole.

Obesity is becoming an epidemic health problem and is associated with concomitant diseases, such as sleep apnea syndrome and gastroesophageal reflux disease (GERD). There is no standardized diagnostic workup for the upper gastrointestinal tract in obese patients; many patients have no upper gastrointestinal symptoms, and few data are available on safety of endoscopy in morbidly obese patients. ⋯ Upper gastrointestinal endoscopy can be performed safely. However, careful monitoring and anesthesiological support are required for patients with concomitant diseases and those receiving sedation. Because 80% of the patients with pathological findings were asymptomatic, every morbidly obese patient should undergo endoscopy before bariatric surgery because there may be findings that might change the surgical strategy.

Because of uncertainties about the complexity of laparoscopic ventral hernia repair for varying patient populations, surgeons may be reluctant to perform this procedure. This study aimed to delineate the risk factors that can be identified in the preoperative setting predictive of longer operative times and complexity in laparoscopic ventral hernia repair. ⋯ At least 10 preoperatively identifiable patient variables, either alone or in combination, are predictive of prolonged operative times during laparoscopic ventral hernia repair and may be used as surrogates to determine the complexity of a minimally invasive approach.
