Abstract

An umbilical hernia is a protrusion of an intra-abdominal organ fully or part of it from an umbilical opening [1, 2]. In adults, the umbilical hernia is usually acquired which is defined as a defect from 3cm above to 3cm below the umbilicus [3, 4]. As reported in the literature, the incidence of umbilical hernia is reaching 10-25% of all types of hernia [5]. There are many risk factors that increase the chance of developing hernia in general this includes chronic cough, pregnancy, obesity, constipation and heavy weight lifting [1, 4]. The abdominal wall at the level of the umbilicus is connected to the bladder during embryonic period by the urachus which is derived from the embryonic allantois [6, 7]. As the bladder descends into the fetal pelvis, the urachal canal normally obliterates and forms the median umbilical ligament [6-9].
