Duodenal Duplications. Clinical Characteristics, Embryological Hypotheses, Histological Findings, Treatment

Abstract

Duodenal duplications are rare malformations with several anatomical varieties. The preferred treatment for duodenal duplications is complete removal when the location allows it without endangering nearby anatomical structures.

Colonic duplication in an adult who presented with chronic constipation attributed to hypothyroidism

“…Rarely, such duplications present with signs of acute abdomen or acute bleeding [8] . Pyloric and duodenal duplications can mimic hypertrophic pyloric stenosis or a choledochal cyst [5,9,10] . An ovarian cyst should be considered in female patients, and adolescent patients can sometimes have a presumptive diagnosis of Crohn's disease.…”

A rare case of duodenal duplication treated surgically

“…Duodenal duplications can be cystic or tubular, communicating or non-communicating, but the most common type is cystic and non-communicating. These are generally located at the medial border of the first and second parts of the duodenum and extend to the anterior or posterior side [1][2][3] . Duodenal duplication observed in our case was cystic and located in the first and second parts of the duodenum, but it was of the communicating type and located on the antimesenteric side.…”

“…Generally, patients present with a palpable mass in the abdomen, signs of intestinal obstruction, or abdominal pain. Bleeding or perforation caused by peptic ulcer and jaundice, and pancreatitis caused by biliary obstruction may also be the manifestations [1][2][3][4][5][6] . In the current case, occasional attacks of abdominal pain and gastrointestinal obstruction were present.…”

“…In the current case, occasional attacks of abdominal pain and gastrointestinal obstruction were present. Obstruction in non-communicating cystic duplications is defined by compression of the duplication cyst, which is distended by intracystic secretions [1] . However, in our case, which was of the communicating type, it can be described by compression of the cyst, which was filled with the gastric contents but not drained.…”

“…Treatment is mainly surgical and total excision, if possible, is the procedure of choice. However, in some cases, alternative procedures, such as subtotal removal or digestive derivation, are required because of extensive size or location [1] . Here, we present a rare case of duodenal duplication in which the treatment was subtotal excision with intraduodenal cystoduodenostomy.…”
