Study population

This nationwide retrospective observational study included 4,257 adult patients aged 20 years or older who underwent elective surgery for rectal prolapse in Switzerland between January 1, 2013, and December 31, 2022. Patients were identified using ICD-10 and Swiss CHOP procedure codes from the anonymized national inpatient database of the Swiss Federal Statistical Office. The study included abdominal rectopexy, Delorme's procedure, perineal stapled prolapse resection, and Altemeier's procedure. Postoperative outcomes were evaluated according to annual hospital procedure volume.

Groups and cohorts

  • Rectal Prolapse Surgery Cohort

    Adult patients aged 20 years or older who underwent elective surgery for rectal prolapse in Switzerland between 2013 and 2022. The cohort includes patients treated by abdominal rectopexy, Delorme's procedure, perineal stapled prolapse resection, or Altemeier's procedure. Postoperative outcomes were evaluated according to annual hospital procedure volume. All surgical procedures were performed as part of routine clinical care without study-assigned interventions.

    Procedure: Surgical Treatment of Rectal Prolapse

Interventions

  • ProcedureSurgical Treatment of Rectal Prolapse

    Patients underwent elective surgical treatment for rectal prolapse as part of routine clinical care. Procedures included abdominal rectopexy (open, laparoscopic, or robotic), Delorme's procedure, perineal stapled prolapse resection (PSP), and Altemeier's procedure. Surgical approaches were identified using Swiss CHOP procedure codes. No interventions were assigned by the investigators, as this was a retrospective observational study.

What researchers measure

Primary outcomes

  1. In-Hospital mortality following rectal prolapse surgery

    In-hospital mortality was defined as death from any cause during the index hospitalization following elective rectal prolapse surgery. Mortality was assessed using anonymized inpatient data from the Swiss Federal Statistical Office and analysed in relation to annual hospital procedure volume.

    Time frame: During the index hospitalization, from admission until hospital discharge or in-hospital death. As data from the Federal statistical office was completely anonymised no longer follow-up was possible. Mean length of stay was 7 days.

Secondary outcomes

  1. Postoperative complication rate

    Occurrence of postoperative complications during the index hospitalization following elective rectal prolapse surgery. Complications were identified using predefined ICD-10 and CHOP codes from the Swiss national inpatient database.

    Time frame: During the index hospitalization, from admission until hospital discharge or in-hospital death. As data from the Federal statistical office was completely anonymised no longer follow-up was possible. Mean length of stay was 7 days.

  2. Failure-to-rescue rate

    Failure-to-rescue was defined as in-hospital death following at least one major postoperative complication. The rate was calculated as the proportion of patients with major complications who died during the index hospitalization.

    Time frame: During the index hospitalization, from admission until hospital discharge or in-hospital death. As data from the Federal statistical office was completely anonymised no longer follow-up was possible. Mean length of stay was 7 days.

  3. Length of hospital stay

    Duration of the index hospitalization, measured in days. Length of stay was assessed using administrative inpatient data.

    Time frame: During the index hospitalization, from admission until hospital discharge or in-hospital death. As data from the Federal statistical office was completely anonymised no longer follow-up was possible. Mean length of stay was 7 days.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
