Office Hysteroscopy: Distension Media and Pain Management

Abstract

Background: Office hysteroscopy is a safe and effective diagnostic and operative procedure for intrauterine pathology and abnormal uterine bleeding. Although it avoids hospital admission and general or regional anesthesia, pain remains a principal cause of procedural failure and is influenced by cervical manipulation, uterine distension, instrumentation, anxiety, and patient-related factors.

Objective: To review the clinical principles and applications of office hysteroscopy, with emphasis on distension media, procedural techniques, safety considerations, pain mechanisms, and pharmacological and nonpharmacological strategies for improving patient comfort.

Conclusion: Pain control during office hysteroscopy requires attention to patient selection, technique, instrument diameter, distension media, anxiety, and appropriate analgesic or anesthetic measures. Vaginoscopy, mini-hysteroscopes, reduced waiting time, music, and selected local anesthetic techniques may improve tolerance; however, published evidence remains heterogeneous and further research is required to establish standardized pain-control protocols.
