  1. Feasibility of high-volume screening sigmoidoscopy using a flexible fiberoptic endoscope and a disposable sheath system.

    Article - En anglais


    Sigmoidoscopy is an effective screening test for colorectal cancer but has yet to have a major impact on mortality because, in part, of inadequate utilization by physicians.

    To address concerns of inefficient use of time and resources, we examined the feasibility of high volume, single-day flexible sigmoidoscopy (FS) screening sessions using an innovative fiberoptic sigmoidoscope with a disposable sheath system.


    All City of Boston employees over the age of 50 yr (n=6137) were invited by mail to undergo a screening FS at Boston City Hospital (BCH).

    Respondents (n=564) were contacted by phone by the program coordinator on receipt of a prepaid postcard and were scheduled (n=227) consecutively into 15-min slots on 1 of 6 1/2-day (3-h) weekend sessions.

    Preregistration was completed at BCH during the week before each session and included enrollment, completion of a brief risk questionnaire, documentation of informed consent, and bowel prep instructions.

    Procedures were performed by three physician endoscopists rotating among four endoscopy rooms per session.

    Each room was staffed with a nurse to aid in patient care and a technician to set up equipment.


    A total of 198 of the 227 (87%) scheduled patients underwent screening FS during the three sessions.

    Physicians performed a mean of 3.5 procedures per room per hour, or 4.7 procedures per hour overall, with a mean depth of scope insertion of 51 ± 10 cm and a mean procedure time of 4.7 ± 3. (...)
