Local posterior perianal block for proctologic surgery.

We present our experience with proctologic operations under local posterior perianal block (LPPB), along with short- and medium-term results of this technique. A total of 72 patients with proctologic disorders consented to operation under LPPB for stapled hemorrhoidectomy, Milligan-Morgan hemorrhoidectomy, subanodermal fistula resection, perianal abscess revision, and anal tumor electrocoagulation. The anesthetic technique, postoperative complications, the pain score, and follow-up were recorded and analyzed retrospectively. Almost all patients were pain-free during surgery. The pain score in visual analog scale (VAS) during the first 24 hours was 1.6 to 3.4 and varied with the type of surgery performed. At follow-up 1-2 weeks later, the patients were satisfied with LPPB (mean level of satisfaction, 8.6 +/- 1.2 on the VAS). Seventy of 72 patients (97.2%) would willingly have surgery again under LPPB if it was required. This study shows that LPPB can be widely and safely applied in proctologic surgery.
