[Herniation of the cecum and ascending colon through the Winslowi foramen in the bursa omentalis].

Herniation through the foramen of Winslow (HFW) is exceedingly rare, the ileum, coecum or ascending colon is involved mostly. One new case is presented here to illustrate the clinical findings, which are often discreet, and the characteristical radiographic features, which can lead to definitive preoperative diagnosis. Treatment is by surgical reduction of the hernia, resection of non-viable bowel or fixation of coecum and ascending colon. Closure of the foramen is generally considered unnecessary. Without delay in diagnosis and treatment, the former high letality rate of the condition is now nearly zero.
