The reported incidence (0.16-1.5 %) of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is higher than during open cholecystectomy and has not decreased over time despite increasing experience with the procedure. The "critical view of safety" (CVS) technique may help to prevent BDI when certain criteria are met prior to division of any structures. This study aimed to evaluate the adherence of practicing surgeons to the CVS criteria during LC and the impact of a training intervention on CVS identification. ⋯ The CVS criteria were not routinely used by the majority of participating surgeons. Further, one-fourth of those who claimed to obtain the CVS did so inadequately. All surgeons who participated in training showed improvement during their post-assessment. Our findings suggest that education of practicing surgeons in the application of the CVS during LC can result in increased implementation and quality of the CVS. Pending studies with larger samples, our findings may partly explain the sustained BDI incidence despite increased experience with LC. Our study also supports the value of direct observation of surgical practices and subsequent training for quality improvement.

Obstructive sleep apnea (OSA), present in 60-70 % of bariatric surgery patients, is a potentially life-threatening condition when not detected and managed appropriately. The best available method to identify the severity of OSA is polysomnography. However, routine polysomnography measurements have not been accepted as standard modality in bariatric surgery. We report our experience with routine polysomnography in a cohort of patients undergoing bariatric surgery to determine the true prevalence of OSA with respect to the different severity levels as determined by the apnea-hypopnea index (AHI). ⋯ One-third of the bariatric surgery patients have an AHI ≥15/h and would benefit from continuous positive airway pressure therapy. In order to increase perioperative safety and avoid the preventable risk of perioperative complications, we recommend mandatory P(S)G prior to bariatric surgery.

Review Meta Analysis
Systematic review and meta-analysis of minimally invasive versus open approach for pancreaticoduodenectomy.
The technique of minimally invasive pancreatic surgeries has evolved rapidly, including minimally invasive pancreaticoduodenectomy (MIPD). However, controversy on safety and feasibility remains when comparing the MIPD with the open pancreaticoduodenectomy (OPD); therefore, we aimed to compare MIPD and OPD with a systemic review and meta-analysis. ⋯ MIPD can be a reasonable alternative to OPD with potential advantages. However, further large-volume, well-designed RCTs with extensive follow-ups are suggested to confirm and update the findings of our analysis.

Root cause analyses show that up to 70 % of adverse events are caused by human error. Strong non-technical skills (NTS) can prevent or reduce these errors, considerable numbers of which occur in the operating theatre. Minimally invasive surgery (MIS) requires manipulation of more complex equipment than open procedures, likely requiring a different set of NTS for each kind of team. The aims of this study were to identify the MIS teams' key NTS and investigate the effect of training and assessment of NTS on MIS teams. ⋯ MIS teams' NTS are important for workflow and prevention of errors and can be enhanced by working in fixed teams. In the technological complex sphere of MIS, communication revolves around equipment- and patient-related topics, much more so than in open surgery. In all, only a few heterogeneous-design studies have examined this. In the future, the focus should shift to systematically identifying key NTS and developing effective, evidence-based team training programmes in MIS.

Modern management of severe acute complicated diverticulitis continues to evolve towards more conservative and minimally invasive strategies. Although open sigmoid colectomy with end colostomy remains the most commonly used procedure for the treatment of perforated diverticulitis with purulent/faeculent peritonitis, recent major advances challenged this traditional approach, including the increasing attitude towards primary anastomosis as an alternative to end colostomy and use of laparoscopic approach for urgent colectomy. ⋯ This case documents the technical feasibility of a minimally invasive single-stage procedure in a patient with Hinchey IV perforated diverticulitis with diffuse feacal peritonitis. The laparoscopic approach facilitated an effective decontamination of the peritoneal cavity, with a combination of large suction devices and aid of protected retrieval by closed endobags for effectively and completely laparoscopic removal of the solid feacal matter, offering clear advantages and excellent results even in such challenging cases. With necessary expertise, the sigmoid resection can be thereafter safely and entirely performed laparoscopically, the specimen extracted through mini-Pfannenstiel incision, and a laparoscopic intracorporeal transanal circular primary anastomosis performed.
