Supravesical hernias develop at the supravesical fossa between the remnants of the urachus and the left or right umbilical artery. They are exceptional and are often the cause of intestinal obstruction. We report two cases of surgically proven internal supravesical hernias presenting with small bowel obstruction. Abdominal computed tomography showed, for our first case, the relation of the incarcerated intestine anterior to and compressing the urinary bladder. We believe that the preoperative diagnosis of supravesical hernia by abdominal computed tomography is possible, as shown in our first case.

Introduction And Importance: Supravesical hernias are rare internal hernias but potential cause of small-bowel obstruction. The clinical features are often non-specific, preoperative diagnosis is very difficult and is often diagnosed intraoperatively. The exact pathogenesis is unclear with the major risk factors of prematurity, a positive family history, male sex, smoking habits leading to decreased collagen production, advancing age, and conditions characterized by defective collagen synthesis.

Background: Foreign body (FB) ingestion is a common event in children. The management of the ingested FB depends on the location, type, number, size of the FBs, patient age, and symptoms. Although most FBs pass spontaneously through the gastrointestinal tract without causing serious injuries, the ingestion of multiple high-powered magnetic pieces, especially neodymium magnets (NMs) increases the risks of morbidity and mortality.

Internal supravesical hernia is a rare type of internal abdominal hernia with overall incidence <4% of all internal abdominal hernias. The clinical diagnosis is a major preoperative diagnostic challenge for both the surgeon and the radiologist. It is a rare cause of small bowel obstruction, but in case of strangulation it can be fatal and it necessitates urgent surgical intervention.
