VILLARREAL, Ricardo A. et al. Unique diverticulum of jejunum with intestinal obstruction and acute abdomen. []. , 34, 1, pp.69-74. ISSN 2011-7582.  https://doi.org/10.30944/20117582.100.

Small intestine diverticulum is a rare finding; it presents more often in the jejunum and ileum. The incidence in autopsies is low (0.06-5%), and 0.5-2.3% as a radiology finding. It is most often found in the 7th decade and in men.

A 90-year-old female patient presented with a clinical picture of one day consisting of acute right abdominal pain that radiates to the hypogastrium accompanied by multiple episodes of vomiting. The patient is admitted and a battery of tests are ordered; during observation the patient quickly deteriorates and is taken to an emergency laparotomy, finding a single jejunal diverticulum. Small intestine diverticuli are rare surgical findings (0.9-1%) that involve only the mucosa and submucosa. The majority of small intestinal diverticuli are found in the jejunum.

These can be associated with diverticuli in other areas of the GI tract: stomach (2.3%), duodenum (30%) and colon (61%). The management approach depends on each patient’s clinical presentation.
