“…In this patient, we incidentally found a type III AVA during surgery for suspected acute appendicitis, which is fully consistent with the literature about this medical rarity 5 6 8–10 15. However, acknowledge that AVA diagnosis should not be made lightly.…”

“…The vermiform appendix appears at 8 weeks of gestation as a diverticulum in the embryonic cecum, then a funnel-like thinning of the lower cecal segment and elongation occur, and it becomes fully developed at 10 weeks. Few aetiological hypotheses that might cause a failure during this process and origin AVA are recognised, such as a secondary effect of maternal ingestion of thalidomide during pregnancy, or as a result of an intrauterine vascular accident 6 9 15 22. Autoamputation has been described as a reason for absent appendix, which might also be an acquired condition 6 23…”

Rare paediatric case of agenesis of the vermiform appendix, ileal duplication and sickle cell disease

This study reports an exceptional case of a 14-year-old girl with sickle cell disease that was diagnosed with agenesis of the vermiform appendix and ileal duplication. Both consist of extremely rare gastrointestinal malformations whose association has never been described. The preadolescent girl presented with abdominal pain and vomiting, and the ultrasound was suggestive of acute appendicitis. Surgical findings were agenesis of the vermiform appendix and a T-shaped ileal malformation with inflammatory changes. The patient underwent resection and ileal end-to-end anastomosis. Histopathological evaluation identified an ileal duplication, with small bowel and colonic mucosa, no communication to the adjacent ileum and ischaemic changes. At 8-month follow-up, the patient was asymptomatic.

“…Agenesis may be because of lack of a growth differential between the cecum and appendix during development, thus making discrimination between these two structures difficult. Intussusception, volvulus, and autoappendectomy must be ruled out by thorough inspection when making a diagnosis of appendicular agenesis (Manoil, ; Skandalakis et al, ).…”

New research on the vermiform appendix has shed light on its function. In further understanding the function of the appendix, this information should not negatively impact the clinical judgment in the event of appendicitis. Although the appendix and its pathology have been noted for centuries, it still presents a challenge in the operating room. The most common emergency surgical procedure performed is an appendectomy. Its highly variable position within the abdomen can cause confusion for clinicians. However, improved imaging modalities have heightened the physician's ability to diagnose disease of this organ. This article reviews germane literature regarding the human vermiform appendix.
