Background:

Obturator hernias are uncommon abdominal wall defects.
This study reviews obturator hernia cases at Mayo Clinic over 15 years.

Observation:

Eight patients underwent nine operations for 11 obturator hernias (0.073% of all hernia repairs).
Elderly women with chronic conditions were most affected.
Mechanical small intestinal obstruction and thigh/groin pain were common symptoms.

Findings:

Preoperative diagnosis was rare (1/8 patients); Howship-Romberg sign present in only two.
Incarcerated ileum was the most common content; endometriosis found in obturator defects in two patients.
Right-sided hernias were more common; bilateral hernias occurred synchronously and metachronously.

Implications:

Obturator hernias present diagnostic challenges, often leading to delayed treatment.
Patient debilitation and diagnostic delays increase operative morbidity and mortality.
Endometriosis is a rare but notable cause of obturator hernia symptoms.
