[Randomised comparison of different exit strategies in hydrocele resection].

Abstract

Introduction: Adult hydrocele is a benign enlargement of the scrotum seen in approximately 60/100,000 men >18 years of age. Surgical resection of the hydrocele has been established as the gold standard for the treatment of symptomatic hydroceles. Postoperative complications are common with this surgery. Due to the lack of guidelines for the therapy of hydrocele, treatment is based primarily on clinical experience. The aim of the study was to conduct a randomised study on the influence of drains on complications in hydrocele resection according to von Bergmann.

Material and methods: A total of 60 patients were prospectively randomised into three groups. The groups each received an Easy-Flow drainage, a Cuti-Med Sorbact drainage, or no drainage. Haematoma and swelling, postoperative bleeding, infection, epididymal injury and revision surgery were clinically diagnosed as complications.

Results: A complication was observed in 31.6% (n=19/60) of all patients. The complication rate was 50% (n=10) for the easy-flow drainage, 30% (n=6) for the Cuti-Med-Sorbact and 15% (n=3) for the group without drainage. Overall, a haematoma with swelling was observed most frequently, in 20% (n=12) of the cases. Revision surgery was required in 5% (n=3) of cases. Epididymal injuries were found histologically in 10% (n=6). Comparing the collective with the Easy-Flow drainage with the collective without drainage, the occurrence of complications was observed significantly more frequently in the drainage group (p<0.018). A statistically significant correlation regarding complications between the group of Cuti-Med-Sorbact and no drainage could not be shown (p<0.25).

Conclusions: Hydrocele resection is a complicated procedure. Based on the data presented here, the insertion of a drain is associated with an increased risk of postoperative complications. If the decision to insert a wound drainage is made intraoperatively, the Cuti-Med-Sorbact drainage appears to be associated with fewer complications.
