Virtual reality simulator training for laparoscopic colectomy: what metrics have construct validity?
Virtual reality simulation for laparoscopic colectomy has been used for training of surgical residents and has been considered as a model for technical skills assessment of board-eligible colorectal surgeons. However, construct validity (the ability to distinguish between skill levels) must be confirmed before widespread implementation. ⋯ The virtual reality simulators for laparoscopic sigmoid colectomy demonstrated construct validity for 8 procedure-specific metrics. However, using virtual reality simulator metrics to detect intraoperative errors did not discriminate between groups. If the virtual reality simulator continues to be used for the technical assessment of trainees and board-eligible surgeons, the evaluation of performance should be limited to procedural metrics.

After more than a decade of improvement, our enhanced recovery pathway had patients who had undergone laparoscopic colectomy going home a mean 3.7 days postoperatively. We wondered if adding a transverse abdominus plane block and intravenous acetaminophen to an established pathway would improve outcomes and resource use. ⋯ The addition of a transverse abdominus plane block and acetaminophen significantly reduced length of stay more than that seen with a previously established pathway. Statistical process control demonstrated that our pathway changes significantly reduced the spread of outliers around our mean length of stay.
