Fig. 3 —57-year-old man with intraoperative laparoscopic view of
right direct inguinal hernia. Open arrows show inferior epigastric artery and
solid arrows show inguinal ligament, which define lateral and inferior
boundaries of Hesselbach's triangle through which direct hernia defect (D) is
distended by gas used during laparoscopy. Deep inguinal ring (curved
arrow) is closed by gas pressure, but medial boundary
(arrowheads) can be seen. Note that extraperitoneal fat obscures vas
deferens, external iliac artery, and other anatomic details.
