A technique for enhancing the visualization of "peritoneal sacs" during inguinal herniography.

Increasing intraperitoneal pressure during inguinal herniography by inducing infants to forcefully cry and older children to forcefully cough will enhance opacification of peritoneal sacs that are either not apparent or only minimally opacified during routine filming. The maneuver is performed with fluoroscopy, and spot films are obtained. The technique is discussed and three cases are illustrated.
