Hernias through a normal orifice include lesser sac hernias through the foramen of Winslow, as well as paraduodenal hernias through the fossae of Waldeyer and Landzert. Hernias through unusual fossae or recesses include paracecal hernias and result in displacement of the cecum anteriorly and medially.
Approximately 75% occur on the left and involve the paraduodenal fossa (Landzert's fossa).
During dissection of a 45-year-old male cadaver, left paraduodenal hernia was observed with contents being first few centimetres of the jejunum into the fossa of Landzert. Inferior mesenteric vein with the ascending branch of left colic artery was lying close to the mouth of the sac.
When there occurs a failure in fusion, a potential space is created behind the descending mesocolon called as the fossa of Landzert. Invagination of small intestine into this fossa leads to left PDH.
Left paraduodenal hernias (LPDHs) into the fossa of Landzert are the more common type and result from abnormal rotation of the midgut and failure of peritoneal fusion [2, 3].
An LPDH diagnosed with a long segment of jejunum was seen herniating through a defect to the left of the fourth part of the duodenum and accumulating in the fossa of Landzert (Figures 1 and 2).
Paraduodenal hernias into the left paraduodenal fossa of Landzert are three times more common than those into the right paraduodenal fossa of Waldayer [2].
Caption: FIGURE 1: Intraoperative photograph showing left paraduodenal hernia: left paraduodenal hernia (LPDH) occurring when small intestine prolapses posteroinferiorly into this fossa (of Landzert), which is bounded by the fourth part of the duodenum, the posterior peritoneum, the inferior mesenteric vein, and left branches of the middle colic artery.
This transition of the fourth portion from a retroperitoneal to an intraperitoneal position creates the paraduodenal recesses of Landzert (on the left) and Waldeyer (on the right), which are potential sites of internal hernias.
