title: Pneumatosis coli and sigmoid volvulus: a report of 4 cases.
abstract: Pneumatosis coli is an uncommon disease which is frequently misdiagnosed and inappropriately treated. The condition can usually be managed conservatively but complications requiring surgical treatment are occasionally encountered. We describe 4 patients with pneumatosis coli and associated volvulus of the sigmoid colon. Some of the factors that may have contributed to pneumocyst formation in these 4 patients are discussed with reference to recent advances in our understanding of the pathogenesis of pneumatosis coli.
