Case report: a case of foramen of Winslow hernia causing portal venous compression.

Foramen of Winslow hernias are a rare pathology that often have a delayed diagnosis and can lead to bowel obstruction and ischemia. We present a case of pre-operatively diagnosed foramen of Winslow hernia in a female in her 70s that presented with right upper quadrant pain. This involved herniation of the colon, causing transient portal venous compression. In this case it was managed operatively with a laparoscopic converted to open reduction of the herniated colon, with resolution of venocongestion post operatively.
