[Two cases of rare abdominal hernias]

Two cases of rare abdominal hernias were presented: sciatic and obturator. Both presented cases confirm diagnostic difficulties, often leading to delay in therapy. The best way to reduce mortality in these patients seems to be the increase of number of preoperative diagnoses. In obturator hernia's diagnosis the attention is payed to Romberg's symptom, although in sciatic--to symptoms of sciatic nerve irritation or anuria. All diagnostic doubts should be solved with the help of herniography or pelvic CT.
