Jejunal diverticula (JD) are uncommon and are usually asymptomatic; however, they can lead to obstruction, hemorrhage, and perforations. True incidence is hard to determine given their anatomic site and relative difficulty to confirm. An enteroclysis study of 520 subjects placed the incidence at 2.0% to 2.3%.1-3 Most patients are in their sixth or seventh decade of life.3,4 Patients with JD also have an increased incidence of diverticula elsewhere in the gastrointestinal tract. Makris et al2 summarized multiple studies that have shown incidences to be 2% in the esophagus, 2% in the stomach, 15% to 42% in the duodenum, and 30% to 75% in the colon.
