Outcome of anorectal surgery under a mixture of local anesthesia : experience with 350 patients

Abstract EN

Background : anal diseases are common surgical problems.

Anal surgical operations are usually carried out under general anesthesia and spinal anesthesia.

The use of local anesthesia in anal surgery is supposed to be safe, simple and efficient.

Purpose : to evaluate the effectiveness and usefulness of local anesthesia for various anal surgeries, and to assess the patient acceptance and satisfaction.

Patients and methods : a total of 350 patients with various anal problems presented to different anal surgeries under local anesthetic infiltration for the period from February 2011 to March 2014.

Age ranges from 18-72 years (mean 47.7 year).

Majority of the patients were males (No.

= 310, 88.6 %) and minority were females (No.

= 40, 11.4 %).

Pain during surgery and postoperatively was evaluated on a visual analog scale.

The feasibility, tolerability and patient's satisfaction with the results of operations were assessed and evaluated.

Results : The mean operations time was 25 minutes range from 10-45 minutes.

The mean pain score in the day of operation was low, (2.8) and the mean pain score in the first postoperative day was also low (3.3).

Most patients (82.85 %) were satisfied with the results of operations and they would prefer local anesthesia again for anal surgery in the future were necessary.

Complications rate in this study was 10.9 % and most these complications managed conservatively.

Conclusion : perianal block by local anesthetic infiltration is safe, simple and effective for various anal operations with very high degree of acceptance and satisfaction among patients.

It had been found to be associated with low pain score and postoperative complications and faster return to daily social activity.

The cost saving had been significant.
