Current Advanced Studies on Adenomyoma of the Small Intestine

The gastrointestinal tract adenomyoma is an uncommon benign tumor-like disease. The second most common site is the small intestine, which commonly occurs in the periampullary region, although the lesion can also occur in the jejunum and ileum. While Vaterian adenomyoma is most commonly identified in adults, juvenile patients account for more than half of all documented instances of jejunal and ileal adenomyoma. The periampullary adenomyoma generally causes biliary obstruction or abdominal pain, whereas the jejunal and ileal adenomyoma generally causes intussusception or is discovered accidentally during surgery or autopsy. Histopathological study is critical in adenomyoma diagnosis since endoscopic and radiographic examinations show non-specific results. Adenomyoma is a pathological condition in which glandular structures of varying sizes are surrounded by interlacing smooth muscle bundles. The pathogenesis of adenomyoma is thought to be either a kind of hamartoma or a pancreatic heterotopia. Despite the fact that restricted resection is the most appropriate therapy, pancreaticoduodenectomy is frequently performed when the lesion arises in the periampullary region due to a preoperative misdiagnosis as a carcinoma. As a result, it's critical that physicians and pathologists keep up to date on the condition to prevent making incorrect diagnoses that lead to unneeded surgery.
