Pilot Trial of Novel Circumcision Device

This study has been completed.

The investigators are testing a novel surgical device to facilitate safe circumcision among adult males. The investigators hypothesize that this device will allow non-medical providers to perform safe surgical circumcision without adverse events.

Condition Intervention
Safe Circumcision Procedure: circumcision with simple circumcision device

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Simple Circumcision Device: Proof-of-Concept for a Single-visit, Adjustable Device to Facilitate Safe Adult Male Circumcision

Further study details as provided by John Krieger, VA Puget Sound Health Care System:

Primary Outcome Measures:
  • Efficacy, injury rate, conversion to standard method rate and cosmetic outcomes of novel surgical device [ Time Frame: 90 days ]
    To determine if the novel surgical device was able to facilitate safe circumcision among adult males. Specifically we looked at: time of surgery, blood loss, ease of use, cosmetic outcome, number of sutures required, need for conversion to another method of circumcision and need for revision surgeries.

Secondary Outcome Measures:
  • Time of circumcision [ Time Frame: 1 day ]
    To determine how long the operative procedure required to complete

Enrollment: 5
Study Start Date: September 2011
Study Completion Date: October 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: circumcision with simple circumcision device
    Circumcision performed with the device in the operating room using local anesthesia
Detailed Description:

Objective: To conduct a proof-of-concept study to determine the potential utility of a novel, adjustable single-visit, disposable device to facilitate rapid adult circumcision.

Design: Prospective pilot trial of a novel surgical device Setting: Tertiary care Veterans Administration medical center Patients: 5 adult males Interventions: Circumcisions performed by junior trainees using an adjustable, single-size surgical-assist device constructed by the University of Washington Applied Physics Laboratory.

Main Outcome Measure(s): The attending surgeon and trainees completed standardized forms after each procedure to assess technical problems and ease of use. Follow-up visits were scheduled to evaluate adverse events, post-operative pain, cosmetic outcomes and participant satisfaction at 3, 8, 30 and 90 days post-operatively.
