Resumen

TROLLIP, G S et al. Vasectomy under local anaesthesia performed free of charge as a family planning service: complications and results. SAMJ, S. Afr. med. j. [online]. 2009, vol.99, n.4, pp.238-242. ISSN 2078-5135.

OBJECTIVE: To evaluate the safety and efficacy of vasectomy performed under local anaesthesia by junior doctors at a secondary level hospital as part of a free family planning service. METHOD: Men requesting vasectomy were counselled and given written instructions to use alternative contraception until two semen analyses 3 and 4 months after vasectomy had confirmed azoospermia. Bilateral vasectomy was performed as an outpatient procedure under local anaesthesia by junior urology registrars. Statistical analysis was performed using the Mann-Whitney, Kruskal-Wallis, Fisher's exact or Spearman's rank correlation tests as appropriate. RESULTS: Between January 2004 and December 2005, 479 men underwent vasectomy at Karl Bremer Hospital, Western Cape, South Africa; their average age was 36.1 (range 21 - 66) years, they had a median of 2 (range 0 - 10) children, and only 19% had 4 or more children. The average operation time was 15.5 (range 5 - 53) minutes. Complications occurred in 12.9%; these were pain (7.3%), swelling (5.4%), haematoma (1.3%), sepsis (1%), difficulty locating the vas (1%), vasovagal episode (0.6%), bleeding (0.6%), wound rupture (0.4%) and dysuria (0.2%) (some men had more than one complication). Of the men 63.3% returned for one semen analysis and 17.5% for a second. The vasectomy failure rate ranged from 0.4% (sperm persisting >365 days after vasectomy) to 2.3% (sperm seen >180 days after vasectomy and/or in the second semen specimen). No pregnancies were reported. The complication (5.6%) and failure rates (0%) were lowest for the registrar who had performed the smallest number of vasectomies and whose average operation time was longest. Comparing the first one-third of procedures performed by each of the doctors with the last one-third, there was a significant decrease in average operating times but not in complication rates. CONCLUSIONS: Vasectomy can be performed safely and effectively by junior doctors as an outpatient procedure under local anaesthesia, and should be actively promoted in South Africa as a safe and effective form of male contraception.
