Endometrial Biopsy

The aim of this study is to determine if 5g of self-administered topical 2.5% lidocaine/2.5% prilocaine cream, reduces pain during IUD insertion and/or endometrial biopsy. The proposed study is a double-blind, placebo-controlled RCT. Each participant will be randomly assigned to one of two arms: 1) Intervention (5g of 2.5% lidocaine/2.5% prilocaine cream in a pre-filled vaginal applicator). 2) Placebo (5g of VersaPro cream in a pre-filled vaginal applicator). Participants will be asked to self-administer the pre-filled vaginal applicator at least 10-15 minutes prior to the procedure. The patient will be asked to rate their pain throughout various steps of the procedure and complete a post-procedure survey afterwards. The primary outcome is global pain score, which will be patient-reported by the 100 mm Visual Analogue Scale (VAS) 5-minutes following the procedure (endometrial biopsy or IUD insertion).

The primary aim of this study is to rigorously compare the efficacy of two commonly used endometrial sampling devices, the Pipelle and the Miltex, these devices are standard of care at Maimonides. This primary objective is critical, as the ability to accurately reach the uterine cavity is fundamental to obtaining adequate samples for histopathological evaluation, which is crucial for diagnosing endometrial cancer and other uterine pathologies.

The aim of this study is to determine if 3ml of inhaled Methoxyflurane, in the form of a Penthrox inhaler, reduces pain during IUD insertion and/or endometrial biopsy. The proposed study is a double-blind, placebo-controlled RCT. Each participant will be randomly assigned to one of two arms: 1. Intervention (3ml of Methoxyflurane via a Penthrox inhaler) 2. Placebo (3ml of normal saline via an identical placebo Penthrox inhaler) The primary outcome is global pain score, which will be patient-reported by the 100 mm Visual Analogue Scale (VAS) 5-minutes following the procedure (endometrial biopsy or IUD insertion).
