Brief Summary:
The stapled transanal rectal resection (STARR procedure) is an effective treatment for obstructed defecation syndrome (ODS) caused by intussusception and rectocele. Recently a new technique has been developed using the new Contour® TranstarTM stapler, which was specifically designed to facilitate the STARR procedure. The investigators would like to evaluate the morbidity and quality of life.

Arm Intervention/treatment
Stapled transanal rectum resection
patients operated with stapled transanal rectum resection
Procedure: Stapled transanal rectum resection
Contour Transtar-STR5G (Ethicon EndoSurgery Inc., Cincinnati, OH).The circular anal dilator is fixed to perianal skin.Rectal intussusception is evidenced with a swab.The first stitch is placed superficial on top of the intussusception. The procedure is performed 5to6 times counterclockwise.A final stitch for first radial cut at 3 o'clock.The device is introduced into the rectum. This cut opens the prolapse. Check with a finger the vagina. The device is then closed and fired. After replacing the cartridge, the device is introduced in the rectum, placed parallel to the circular anal dilator and moved counter clockwise with 4to6firings to complete the resection. Additional stitches across the staple line to assure haemostasis.

Primary Outcome Measures :
  1. Quality of Life [ Time Frame: 6 months after intervention ]

    Quality of life is measured by Fecal incontinence quality of life (FIQL)

    Possible range of score 0 - 4 (Depression/Self perception 4.4)

    0 = worst condition

    • Fecal Incontinence Quality of Life (FIQL) (Rockwood, Dis Colon Rectum (2000) 43:9)

Secondary Outcome Measures :
  1. Morbidity [ Time Frame: 1 year ]
    Surgical complications after treatment according to Dindo (Ann Surg (2004) 240:205)

  2. Hospitalization [ Time Frame: 1 day to 1 year (until release from hospital) ]
    Length of hospital stay (Date of release - Date of admission + 1)

Other Outcome Measures:
  1. Severity of Symptoms Score [ Time Frame: before surgery - 6 weeks - 3 months - 6 months ]

    Score based on the severity of 9 symptoms of bowel movement (physician administered)

    (0 - 36, no symptoms = 0)

    Dis Colon Rectum 39:681 (DOI: 10.1007/BF02056950)

  2. Obstructive Defecation Syndrome Score [ Time Frame: before surgery - 6 weeks -3 months - 6 months ]

    Score based on severity or frequency of 9 symptoms of obstructive defecation (physician administered)

    (0 - 40, no symptoms = 0)

    Dis Colon Rectum 51:348(DOI: 10.1007/s10350-007-9115-1)

  3. SF36 Component Summary Scores [ Time Frame: Before surgery - 6 months ]

    Quality of life short form 36 version 2(SF36v2) standard form

    PCS: physical component summary score (range 1 to 81, with 81 being the best) MCS: mental component summary score (range -9 to 82, with 82 being the best)

    A score of 50 correlates with the result of a healthy standard US population (score transformation to a mean of 50 and a standard deviation of 10)
