Congenital band adhesion causing a proximal jejunal obstruction: an uncommon presentation and diagnosis.

A 20-year-old woman with no medical or surgical history presented with acute onset crampy abdominal pain on a background of uninvestigated similar chronic abdominal pain. She became obstructed during her admission and a contrast swallow showed a complete obstruction at the level of the proximal jejunum. A diagnostic laparoscopy revealed a congenital band adhesion from the greater omentum to the proximal jejunum to be the cause, and dissection of the band relieved her obstruction. This case presents a rare cause of mechanical obstruction, and highlights the seriousness of investigating obstructive symptoms even in atypical patient populations.
