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 Comparative Study
Intracorporeal versus extracorporeal anastomosis in right hemicolectomy: a systematic review and meta-analysis.
Laparoscopic right hemicolectomy for colon cancer is associated with substantial morbidity despite the introduction of enhanced recovery protocols and laparoscopic surgery. Laparoscopic right hemicolectomy with an intracorporeal anastomosis (IA) is less invasive than laparoscopic assisted hemicolectomy, possibly leading to further decrease in post-operative morbidity and faster recovery. The current standard technique includes an extracorporeal anastomosis with mobilization of the colon, mesenteric traction and a extraction wound located in the mid/upper abdomen with relative more post-operative morbidity compared to extraction wounds located in the lower abdomen. ⋯ Intracorporeal anastomosis in laparoscopic right hemicolectomy is associated with reduced short-term morbidity and decreased length of hospital stay suggesting faster recovery as shown in this meta-analysis.

Randomized Controlled Trial
Effects of preoperative ultrasound-guided transversus abdominis plane block on pain after laparoscopic surgery for colorectal cancer: a double-blind randomized controlled trial.
Although laparoscopic colorectal surgery decreases postoperative pain and facilitates a speedier recovery compared with laparotomy, postoperative pain at trocar insertion sites remains a clinical concern. The objective of this study was to assess the effects of a preoperative ultrasound-guided transversus abdominis plane (TAP) block on pain after laparoscopic surgery for colorectal cancer. ⋯ In colorectal cancer patients undergoing laparoscopic colorectal surgery, a TAP block did not offer enough benefit for clinical efficacy in terms of postoperative pain or analgesic consumption.

Multicenter Study Observational Study
Endoloops or endostapler use in laparoscopic appendectomy for acute uncomplicated and complicated appendicitis : No difference in infectious complications.
The most appropriate closure for the appendicular stump with either endoloops or an endostapler in laparoscopic appendectomy remains unclear and under debate because of limited and conflicting evidence. ⋯ The infectious complication rate is not influenced by the type of appendicular stump closure with either endoloops or an endostapler in this study. If technically feasible, closure with endoloops is advised for cost considerations.
