Postoperative pain represents an important issue in traditional hemorrhoidectomy. This meta-analysis suggests that pudendal nerve block is beneficial for pain management.

The aim of this study by the Diseases Of The Colon & Rectum was to investigate the use of pudendal nerve block in patients undergoing hemorrhoidectomy.

PubMed, Google Scholar, Cochrane Library, and Web of Science databases were searched. Randomized trials evaluating the pudendal nerve block effect in patients undergoing hemorrhoidectomy were selected.

A total of 1,214 patients was included, of whom 565 received the pudendal nerve block.

--After hemorrhoidectomy, patients in the pudendal nerve block group received opioids less frequently and in a lower cumulative dose.

--Moreover, these patients experienced less pain at 24 hours, had a shorter length of hospital stay, and a lower readmission rate.

This systematic review and meta-analysis show significant advantages of pudendal nerve block use. A reduction in opioid consumption, postoperative pain, complications, and length of stay can be demonstrated. Despite limitations, pudendal nerve block in patients undergoing hemorrhoidectomy should be taken into account.
