The implementation of a PCR method showed an increase de 117 positive results (73.1% of discrepant). Considering the sensitivity of C.diff QUIK CHEK (instructions of manufacturer), the GDH discrepant results may be false negatives, y the samples PCR and toxins positives may be real positives results.

The therapeutic approach in these specific populations is debated and it must consider its etiology and adult guidelines focused on fertility issues, which suggest laparoscopic salpingectomy. We described two adolescent cases (15 years asymptomatic and 13 years with abdominal pain) presenting a monolateral hydrosalpinx secondary to surgery for Hirschsprung's disease and complicated appendicitis, respectively. Both patients underwent to uncomplicated robotic-assisted salpingectomy, with uneventful follow-up and preserved ovarian function. Robotic-assisted salpingectomy for hydrosalpinx secondary to previous surgical conditions is a safe and careful approach for adolescents in order to preserve ovarian vascularization, function and future fertility.
