未経験術者がHoLEP (Holmium Laser Enucleation of the Prostate) に早期習熟するための提案

Abstract

Holmium laser enucleation of the prostate (HoLEP) is a safe and effective treatment for patients with symptomatic benign prostatic hyperplasia (BPH), but is a difficult operation. To shorten the learning curve, we evaluated the surgical outcome of successive bilateral lobe enucleations with HoLEP. Performed by an inexperienced endourologist and an expert. Between March and July on 2009, we evaluated 20 cases of HoLEP performed by a beginner who underwent successive bilateral lobe enucleations and 20 cases of HoLEP performed by an expert. Enucleation time was shortened when successive bilateral lobe enucleations were performed by the beginner using HoLEP (115 vs 92 minutes, p＜0.05). The enucleation time was significantly shorter in the expert group than in the beginner group. However, there were no significant differences in morcellation time, enucleated tissue weight, hemoglobin decrease level, sodium decrease level, catheterization time or significant incontinence time between the two groups. The postoperative evaluations was excellent in both groups. We conclude that HoLEP is a safe and effective operation. However, close supervision by an expert is required. In addition, learning from the easier part of enucleation to elaborate skill sets required to perform HoLEP is prerequisite for success.
