ABSTRACT
Laparoscopic surgeries were first introduced in the 1980s. More recently, similar techniques such as natural orifice transluminal endoscopic surgery and other advanced transumbilical surgeries have been developed. With all of these surgical advances, basic information about the umbilicus is lacking. This study evaluated the relationship between umbilical diameter and thickness, as well as the underlying vessels, in order to develop a simple means of assessing umbilical anatomy. We retroactively reviewed 842 computed tomography images that included the umbilicus. Umbilical thickness, diameter, type of vessel located beneath the umbilicus, depth to the vessel, and other parameters were measured. Age and sex were noted, and their relationship was analyzed as it pertains to the umbilical anatomy. Average umbilical thickness and diameter were 8.2 mm and 3.5 mm, respectively. Vessels directly under the umbilicus were located on average 60.0 mm from the umbilicus. The most common vessels detected were the aorta and the right common iliac artery. A wider umbilical diameter was correlated with a thinner umbilicus. As natural orifice transluminal endoscopic surgery is relatively new, further studies regarding umbilical anatomy and clinical correlation are warranted. However, this report brings to light the importance of basic umbilical anatomy, and that these characteristics should be taken into account during the laparoscopic entry procedure.
RESUMEN
Las cirugías laparoscópicas se introdujeron en la década de 1980. Recientemente, se han desarrollado técnicas similares, tales como cirugía endoscópica transluminal por orificios naturales y otras cirugías transumbilicales avanzadas. Con todos estos avances quirúrgicos, es insuficiente la información básica sobre el ombligo. Este estudio evaluó la relación entre el diámetro y el espesor umbilical, así como los vasos subyacentes, a fin de desarrollar un medio simple de evaluar la anatomía umbilical. Se revisaron retroactivamente 842 imágenes de tomografía computarizada que incluían el ombligo. Se midió espesor umbilical, diámetro, el tipo de vaso situado bajo del ombligo, y la profundidad junto a otros parámetros. Se observaron edad y sexo, y se analizó su relación en lo que respecta a la anatomía umbilical. Espesor umbilical medio y el diámetro eran de 8,2 mm y 3,5 mm, respectivamente. Vasos directamente bajo el ombligo se localizaron en promedio 60,0 mm del ombligo. Los vasos más comunes detectados fueron la aorta y la arteria ilíaca común derecha. Un diámetro más amplio umbilical se correlacionó con un ombligo más delgado. Como en los orificios naturales la cirugía endoscópica transluminal es relativamente nueva, se justifican más estudios en relación con la anatomía umbilical y su correlación clínica. Sin embargo, este informe pone de manifiesto la importancia de la anatomía básica umbilical, y que estas características se deben tener en cuenta durante el procedimiento de entrada laparoscópica.
