Lateral Internal Sphincterotomy Under Local Anesthesia: A Randomized Clinical Trial
Background: Nowadays there is an attempt to perform lateral internal
sphincterotomy (LIS) operation on an ambulatory basis under local
anesthesia. This study aimed to compare postoperative outcome in local
anesthesia with spinal anesthesia. Methods: A randomized, double
blinded, controlled trial was performed on 62 patients divided into
group A (Local Anesthesia) and Group B (Spinal An-esthesia) with n=31
equally. To achieve adequate anesthesia a cocktail, 6cc of Lidocaine 2%
and Marcaine 0.5% with the addition of some bicarbonate was injected
into subcutaneous tissue and 20 cc of this was injected into the
inter-sphincteric space before LIS. Postoperative pain was assessed by
a 10 cm VAS. Results: Needle pain scores in group A and B were:
2.29±1.40 vs. 16.1±0.88 but pain scores, 6 hours after LIS,
before leaving hospital and at the first week after the operation were
significantly lower in group A than B (1.90±1.07 vs.
3.77±1.25, 0.90±0.47 vs. 1.65±0.75, 0.71±0.46
vs.1.06±0.51 re-spectively). Need of opioid and codeine in the
first 24 hours after the operation in group A was significantly less
than the other group. Also nausea and vomit-ing in group A was
significantly lower than group B. Conclusion: The study showed that LIS
under local anesthesia is a less painful technique in office surgery
