Purpose: We evaluated the usefulness of anal surgery using local perianal block and assessed patient satisfaction.
Methods: From January to October 2008, a total of 41 consecutive patients consented to anal operation with local perianal block for stapled hemorrhoidopexy (n=15), excisional hemorrhoidectomy (n=9), fistulotomy (n=13), or abscess drainage (n=4). Postoperative pain was evaluated on a visual analogue scale (VAS) from 0 to 10. Patient satisfaction was evaluated through telephone interviews.
Results: The mean peak VAS scores on the day of operation were 3.3 after stapled hemorrhoidopexy, 2.9 after excisional hemorrhoidectomy, 2.6 after fistulotomy, and 3.5 after abscess drainage; on postoperative day 1, the scores were 1.3, 1, 0.9, and 2.3, respectively. The majority of patients (31; 86.1%) were satisfied with the postoperative results (very satisfied 12, satisfied 19, only fair 5, unsatisfied 0). More than half of the patients (23; 63.9%) were satisfied with the use of local anesthesia (very satisfied 4, satisfied 19, only fair 12, unsatisfied 1). The mean VAS scores during injection were significantly different between the satisfied group (very satisfied and satisfied) and not-satisfied group (only fair and unsatisfied) treated with the local anesthesia (satisfied group: 3.5 and not-satisfied group: 5.4, P=0.04). Most patients (30; 83.3%) would undergo this anesthetic procedure again if future anal surgeries were necessary.
Conclusion: Local perianal block is feasible for various anal operations and results in a high degree of satisfaction among patients. However, the pain associated with injection has an adverse effect on patient satisfaction.
