Pneumatosis coli and sigmoid volvulus: A report of 4 cases

Abstract

Abstract Pneumatosis coli is an uncommon disease which is frequently misdiagnosed and inapproapriately 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.
