Using the internal inguinal ring as a landmark for the safe placement of secondary trocars at laparoscopy

Abstract

Inferior epigastric vessels; laparoscopic vascular injuries; trans-illumination; internal inguinal ring Aim Avoidance of injury to the epigastric vessels is an important safety consideration in siting secondary ports at laparoscopy. We evaluated trans-illumination, direct visualization of vessels and using the internal inguinal ring, which has a constant relationship with the inferior epigastric vessels as an anatomical landmark to locate these vessels.
