Hysteroscopy without anesthesia: review of recent literature.

摘要

The need for anesthesia or analgesia for performing hysteroscopy is still matter of debate. Many factors explain the lack of agreement about anesthesia in hysteroscopy depending on the instrumentation, technique employed, need of performing surgical procedure, operator skill and patients' characteristics. Diagnostic minihysteroscopy (3.5 mm or less in size) is less painful and easier to perform than hysteroscopy performed with instruments sized around 5 mm. Thanks to miniaturized instruments, office hysteroscopy allows a growing number of women to be treated in an office setting avoiding the operating room. The main limitation to its widespread use is pain and low patient tolerance. Intrauterine surgical procedures involving only the endometrial mucosa (biopsies, adhesiolisis, cervical and endometrial polyectomies) are not painful. For endometrial polypectomy size of polyps (<2.2m) and duration of the procedure (more than 15 min) are limiting factors. Most literature suggests that office hysteroscopy in experienced hands is a well-tolerated technique and requires the use of analgesics only in selected patients like women with previous caesarean section, history of chronic pelvic pain, anxiety and in menopause.
