A Rare Surgical Case of a Posterior Rectus Sheath Hernia Causing Small Bowel Obstruction.

Intraparietal hernias are a rare type of ventral hernia in which the hernia sac is located between abdominal wall layers. A posterior rectus sheath hernia, as described in this case, is a type of intraparietal hernia in which the hernia sac is located between the defect in the posterior sheath and an intact anterior sheath. These hernias can pose a diagnostic challenge and carry a higher risk of incarceration and strangulation, given the intraparietal location and often small size of the defect. Posterior rectus sheath hernias are rare, with only a few reported in the literature. In this case report, we describe a posterior rectus sheath hernia causing small bowel obstruction in a 41-year-old female patient with a surgical history of a cesarean section six weeks prior to presentation.
