We report on a 12-year-old girl who underwent laparoscopic excision of a left-sided hydrosalpinx. She presented with recurrent lower abdominal pain 8 years after appendectomy and resection of the left ovary. Sonography revealed a large cystic, tubular mass cranial and to the left of the urinary bladder. Laparoscopy demonstrated a left-sided hydrosalpinx which was resected endoscopically using a stapler.
