Clinical Analysis of the Hemorrhoidectomy with Pure Local Anesthesia

摘要

Purpose We hoped to evaluate the possibility of substitution of the local anesthesia for the spinal anesthesia in hemorrhoidectomy. Methods We did Milligan-Morgan hemorrhoidectomy under local anesthesia for the sixtyeight patients from January 1998 to December 2005. These patients were compared with seventy-nine patients of spinal anesthesia, sampled with similar gender, age, a surgeon, retrospectively. We used a mixture of 0.5% lidocaine and 1:200,000 epinephrine into perianal skin and intersphincteric space. Results The male-to-female ratio was 1:1 in local anesthesia group and 1:0.84 in spinal anesthesia group. The mean age was 50 and 46 respectively. The number of excised pile was 3.9 and 3.8 respectively. The frequency of the analgegics injected within first 24 hours was 1.79 and 2.70 respectively (P=0.001). The frequency of the urinary catheterization was 0.07 and 0.69 respectively (P Conclusions Local anesthesia is simple, safe and effective in the hemorrhoidectomy.
