Clinical Analysis of the Hemorrhoidectomy with Pure Local Anesthesia

ABSTRACT

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 sixty- eight 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 1200,000 epinephrine into perianal skin and intersphincteric space. RESULTS: The male-to-female ratio was 11 in local anesthesia group and 10.84 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 < 0.001). The first bowel movement after surgery was 1.2 days and 1.6 days respectively. The hospital stay was 6.4 days and 8.1 days respectively (P=0.06). CONCLUISIONS Local anesthesia is simple, safe and effective in the hemorrhoidectomy.
