About the research
Rectal Prolapse Surgery in Switzerland: Hospital Volume and Postoperative Outcomes
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
Inclusion Criteria:
- Age 20 years or older.
- Hospitalization in Switzerland between January 1, 2013, and December 31, 2022.
- Diagnosis of rectal prolapse (ICD-10-GM K62.3).
- Elective surgical treatment of rectal prolapse identified by Swiss CHOP codes 48.49, 48.74, 48.75, or 48.76.11.
Exclusion Criteria:
- Age below 20 years.
- Emergency surgery.
- Non-operative treatment of rectal prolapse.
- Incomplete documentation.
- Unspecified surgical procedures or CHOP codes not corresponding to the predefined eligible procedures (e.g., 48.76.00).
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.

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
Surgical Treatment of Rectal Prolapse PROCEDURE
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 are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
In-Hospital mortality following rectal prolapse surgery
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.
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.
Secondary measures
Postoperative complication rate
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.
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.
Failure-to-rescue rate
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.
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.
Length of hospital stay
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.
Duration of the index hospitalization, measured in days. Length of stay was assessed using administrative inpatient data.
