- Abstract
Background: Lymphatic obstruction by Wuchereria bancrofti is thought to be the mechanism for development of tropical hydrocele in men and for elephantiasis, mostly in women. Hydrocele prevalence is used to determine the effectiveness of para site eradication programs. Methods: We maintained a prospective log of operations performed at 1 Canadian Field Hospital during its relief mission to Léogâne, Haiti. Information regarding duration of symptoms, type of previous surgery (if any), surgical approach, associated inguinal hernia and volume and appearance of hydrocele fluid in patients with tropical hydroceles were recorded. Results: From January to March 2010, 4922 patients were seen, none of whom had elephantiasis. Of the 64 patients who collectively underwent 69 inguino-scrotal pro - ced ures, 5 patients had inguinal hernia repair several years after hydrocele excision via the scrotum, 19 patients with bilateral hydroceles underwent a scrotum-only approach, and 45 patients had an inguinal approach (33 unilateral and 12 bilateral) to repair 57 hydroceles. A patent processus vaginalis was present in 50 of 57 (88%) hydroceles where the groin was explored. Conclusion: Hydroceles remain common in Léogâne despite successful eradication of filariasis with mass drug administration using diethylcarbamazine-fortified cooking salt. Persistent patent processus vaginalis is a more likely cause than persistent filariasis. There is probably little difference between hydrocele in developed countries and tropical hydrocele other than neglect. Hydrocele prevalence is not a measure of the effectiveness of parasite eradication programs.
