To investigate the clinical features, diagnosis and treatment of small intestine diverticulum.

Clinical data of thirty-nine cases with small intestinal diverticulum were collected and retrospectively analyzed from January 2010 to December 2015.

All the 39 patients received surgical treatment, including 13 cases of diverticulum, 12 cases of partial resection, 5 cases of multiple resection, and 9 cases of partial colectomy due to acute abdomen. The diverticulum diameter was 1.0-4.0 cm; 14 cases with different degree of mucosal hyperemia, edema or necrosis; 8 cases with calculi; 4 cases showed ectopic tissues; 3 cases were found non-malignant hemangioma. All patients were healed and discharged, abdominal distension and pain, watery diarrhea or constipation and other clinical symptoms significantly relieved in 32 cases, 5 cases obtained partial remission, while no clinical changes in 2 cases.

The diagnosis of small intestine diverticulum is mainly based on colonoscopy and CT. The general condition of patients, local inflammation, complications and size, location and number of diverticulum affect the appropriate treatment, according to which the surgical procedures can be designed.
