Nonmeckelian jejunoileal diverticula (JID) are rare, but potentially clinically significant lesions. Despite recent advances in modern diagnostic modalities, diagnosis of JID may be problematic. Upper gastrointestinal contrast series with small bowel follow-through examination and mainly enteroclysis are the 2 main diagnostic methods. In selected cases (mainly complicated JID), the physician could use other diagnostic methods, such as ultrasound, computed tomography, endoscopy, intraoperative endoscopy, laparoscopy, radiotagged erythrocyte bleeding scans, and selective mesenteric arteriography. JID may be clinically silent or symptomatic causing chronic pain or malabsorption or other acute complications, such as hemorrhage, inflammation, perforation, etc. Laparotomy remains the gold standard for definite diagnosis of asymptomatic and complicated diverticula. Treatment should be individualized. Surgery could be indicated, mainly in symptomatic diverticula. The extent of resection may be a problem, especially in patients with extensive disease involving large parts of the bowel. In these cases, clinical judgment is required from the part of surgeon to avoid short bowel syndrome.
