A 99m Tc-pertechnetate scan for the detection of Meckel
's diverticulum should be considered in young patients with overt bleeding and a negative evaluation (using other diagnostic modalities) (2).
La embriogenesis de la mandibula se inicia a finales de la cuarta semana de gestacion a partir: del cartilago de Meckel
del primer arco faringeo, de las celulas de la cresta neural, del endodermo y de la interaccion de varias vias moleculares, como SHH.
After the afferent fibers converges from three main sensory roots of the nerve ([V.sub.1], [V.sub.2] and [V.sub.3]) the main trunk of trigeminal nerve enters throught porus terminus, an opening into the dura mater while entering the Meckel
's diverticulum (MD) is a congenital malformation of the gastrointestinal tract.
's diverticulum (MD) is a congenital abnormality of the gastrointestinal tract.
With regards to the viscerocranium components which shares in formation of different structures of the sound transmitting apparatus; the ventral component of the mandibular arch (Meckel
's cartilage primordium; M.C.PR) and the dorsal component of the mandibular arch (pterygoquadrate; P.Q) appears as mesenchmatous structures (Figure 2).
One of the most common cause of paediatric surgical referral is inguinal hernia.1 Its reported prevalence in mature infants is upto 15% while it is slightly higher in pre-mature infants where it is reported to be between 10-30%.1,2 Its cause is failure of closure of processus vaginalis in children and it may contain all types of contents such as ovaries, fallopian tubes, Meckel
's diverticulum, gut etc.3 Depending upon the type of unsual contents; these hernias are named differently as Littre's hernia if the sac contains Meckel
diverticulum or Richter henia if the sac contains a portion of the circumference of intestine.3,4 Both these types are quite well known in literature but there is a third type which is relatively not very well known, called as Amyand's hernia.
In children past infancy and in atypically located Intussusception discrete lead point is usually identified, Meckel
The most frequent aetiological factors were various malignancies (10 cases, 28.5%) and perforation of Meckel
's diverticulum (8 cases, 22.8%).
Uncomplicated extensive jejunal diverticulosis and meckel
diverticulitis were seen (Figure 2a, 2b).
