Context: Primary vaginal hydrocele is commonest disease worldwide. In tropics lymphatic filariasis is main cause. Surgery is treatment of choice. A number of methods are described. “Sac eversion with minimal separation” is described to have many advantages. This study is done to know the efficacy of the method over others. Aims: To study the efficacy of “Sac eversion with minimal separation technique”. Settings and Design: Prospective experimental study, General Surgery department of Narayana Medical College from 15th October 2014 to September 2016. Methods and Material: Detailed history, clinical examination, investigations from patients with primary vaginal hydrocele is noted in proforma. All are operated by this technique. Post operative complications are documented. Statistical analysis used: Percentages and mean. Results: Among 64 cases maximum incidence was found in 3rd decade, agriculturist and coolies. Many cases presented with symptoms for 2 - 4 years. Right sided scrotal swelling was common. Scrotal odema was the common complication. Average hospital stay was 2 days. Conclusions: This technique is good compared to conventional procedures because it is much easier and simpler, consumes less time, can be done with small incision under local anesthesia. As the sac is not stripped from the surrounding scrotal tissues, bleeding is minimal, post operative haematoma does not occur and other complications like pain, fever, infection, disruption of wound are prevented.
