Diverticula of the small intestine are relatively rare. A retrospective analysis of 4 cases of the practice of Department of General and Hepatopancreatic surgery, University Hospital "Alexandrovska"--Sofia was performed. Two patients are with Meckel diverticulum--the first one with diverticulitis, and the second with perforation and formed abscess cavity. The third case presents a patient with an intestinal loop with diverticula accreted in hernial sack and forth one is with diverticular perforation of the small intestine. All of them underwent surgery. This is accomplished with a literature review presenting the possible diagnostic and treatment modalities applied to this disease. Complications of intestinal diverticulosis often require surgical management in urgent conditions.
