Laparoscopic pyloromyotomy is associated with an increased risk of incomplete myotomy compared with open myotomy. We hypothesized that utilizing ultrasound measured length to direct laparoscopic pyloromyotomy would reduce the risk of incomplete pyloromyotomy without a concomitant increase in the risk of mucosal perforation. ⋯ Preoperative ultrasound measurement of pyloric length to determine the length of laparoscopic pyloromyotomy, rather than visual cues alone, appears to minimize the risk of incomplete pyloromyotomy.
