for 2 days. He was discharged home 7 days after his operation. This is the first reported case of an ultrasound-guided TAP block causing a significant postoperative complication and highlights the potential for iatrogenic injury even when ultrasound is used. The injury here was likely due to a failure to accurately image the entire needle during the right-sided needle placement, resulting in excessive depth of penetration. The iLook machine is marketed for use in vascular access procedures and superficial imaging and as such may not produce images of sufficient quality to be used in this setting. Any practitioner using ultrasound for this type of block should be adequately trained in its use and be fully aware of the potential for complications.
