Introduction: Anorectal surgical procedures are among the most common surgical
operations, with more than 90% of these procedures performed on an ambulatory basis. This
study was designed to assess the two anaesthetic techniques, namely local anaesthesia with
sedation and spinal anaesthesia, with respect to their recovery times, post-operative side
effects, pain scores, patient satisfaction and hospital expenditures in certain proctological
examinations that include ambulatory anorectal surgery.
Materials and Methodology: 80 patients who are considered fit at ASA physical status I, II
and III outpatients scheduled for anorectal surgery were enrolled in this study. Patients were
randomly allotted to receive one of the two following techniques: spinal anaesthesia (Group
1, n = 40) or local anaesthesia with midazolam sedation (Group 2, n = 40).
Results: There was no significant difference for preoperative VAS scores between the two
groups (p > 0.05). VAS scores increased to 3.42 ± 0.5 for Group 1, and to 5.29 ± 1.6 for
Group 2 at the fourth postoperative hour, which predicts a time-dependent increase of mean
scores resulting from the early recurrence of pain. There was no statistically significant
difference in VAS scores between two groups except for the four postoperative hour values.
Conclusion: To conclude that the use of local anaesthesia with sedation for ambulatory
anorectal surgery, when compared with spinal anaesthesia, resulted in a relatively shorter
hospital time, lower hospital expenditures and relatively no undesirable effects.
