Universal Access in Humancomputer Interaction Applications And Services

Single-access laparoscopic surgery (SALS), performed using a single transumbilical access, has recently proved to bring advantages over other forms of laparoscopic surgery due to the reduction in the number of incisions and the consequent decrease in morbidity, less blood loss and postoperative pain. Furthermore, cosmesis may be improved because incision within the umbilicus renders surgery virtually scarless.
