Diagnosis: Obturator hernia on right side
Patient recovered from the bowel obstruction, passing stool spontaneously seven days after the laprotomy.
Obturator hernia is difficult to diagnose clinically because it has an uncommon incidence.
Contrast-enhanced CT is the investigation of choice in diagnosing obturator hernia.
About one-third of these patients develop a syndrome of thigh neuralgia due to the compression of the obturator nerve in the obturator canal.
