In this study we present the technique and results of the use of local perianal anesthetic infiltration for minor anorectal operations.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> In this cohort study patients undergoing surgery for hemorrhoids, anal fissures and low anal fistulas were included. Posterior perineal block was induced with a mixture containing 0.125% bupivacaine and 0.5% lidocaine. All patients were followed up at 30 days either by a post-operative visit or a telephone call and all post-operative complications over the post-operative 30-day period were registered.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> One thousand and twenty-six consecutive patients were included in our study. For all patients' intraoperative analgesia was achieved after performing perianal anesthetic infiltration and no additional support from the anesthesia team was necessary in any of case. Complications were observed in 14 (1.4%). Urinary retention occurred in 5 (0.5%) cases. Six cases of bleeding occurred after hemorrhoidectomy (0.6%) and 1 (0.1%) after lateral internal sphincterotomy. Perianal abscess developed for two patients (0.2%).<\/jats:p><jats:p><jats:bold>Conclusions:<\/jats:bold> Local anesthesia using posterior perineal block technique is safe and effective for intraoperative analgesia in anorectal surgery, saving a substantial operation cost by avoiding the involvement of an anesthesia team and resulting in minimal incidence of urinary retention and other complications.<\/jats:p>","DOI":"10.3389\/fsurg.2021.730261","type":"journal-article","created":{"date-parts":[[2021,9,9]],"date-time":"2021-09-09T11:46:34Z","timestamp":1631187994000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["Local
