  Purpose

The purpose of this study is to determine the level of pain women experience during an endometrial biopsy and the effect that the biopsy tool might have on that pain. The investigators will also evaluate the adequacy of the sample each endometrial biopsy tool collects.


Condition Intervention
Pain
Device: Pipelle de Cornier
Device: Explora curette

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Supportive Care
Official Title: Comparison of Pain Experienced by Patients Undergoing Endometrial Biopsy by Pipelle and Explora Curette

Further study details as provided by Oregon Health and Science University:

Primary Outcome Measures:
  • Compare Pipelle and Explora curette groups with respect to patient perception of pain associated with the procedure as rated by a 10 cm visual analog scale. [ Time Frame: Two Years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Compare study groups in terms of provider's subjective sense of ease of procedure and adequacy of sample obtained for examination by a pathologist. [ Time Frame: Two Years ] [ Designated as safety issue: No ]

Enrollment: 84
Study Start Date: January 2009

Arms Assigned Interventions
Active Comparator: 1 Device: Pipelle de Cornier
A flexible suction cannula 23.5 cm in length with an inner diameter of 2.6 mm and an outer diameter of 3.1 mm. It has a 2.4mm diameter opening on the distal end, on one side of the cannula. It is a disposable polypropylene sheath with an inner plunger and is used for blind endometrial biopsy.
Other Name: Pipelle
Active Comparator: 2 Device: Explora curette
The curette has an outer diameter of 3.0 mm and is slightly more rigid. This cannula has a sharp Randall-type cutting edge on the distal end, on one side of the cannula.
Other Name: Explora

Detailed Description:

Is there a difference in pain perceived by patients undergoing endometrial biopsy via the Pipelle or Explora curette? Currently, the instrument selected for endometrial biopsy is solely dependent on provider preference. This study aims to elucidate advantages and/or disadvantages of the Pipelle versus the Explora curette in terms of pain perceived by the patient, adequacy of sample, and provider ease of use to better aid in the selection of the appropriate device.
