Outpatient care after emergency surgery for gangrenous appendicitis
Official title: Safety, Efficacy, and Cost-effectiveness of Outpatient Surgery for Gangrenous Acute Appendicitis: The PENDI-CSI II Randomized Clinical Trial.
Run by Fundación Pública Andaluza para la gestión de la Investigación en Sevilla · NCT07521969 · Data updated 2026-11-12
This trial will test whether people older than 14 with gangrenous appendicitis can be safely discharged home the same day after emergency appendectomy instead of staying in the hospital.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients over 14 with intra-operative confirmation of gangrenous appendicitis who tolerate oral intake, have no purulent/fecaloid peritonitis or abscess, do not require abdominal drains, are not immunosuppressed or pregnant, and have family support and ability to attend follow-up.
✕Probably not a fit
Patients with generalized purulent or faecaloid peritonitis, appendicular abscess, need for drainage, paralytic ileus, ASA IV or selected ASA III status, immunosuppression, active cancer, pregnancy, lack of family support, or inability to comply with follow-up are unlikely to benefit from outpatient discharge.

What this trial studies
This randomized interventional trial at Hospital Universitario Virgen del Rocío compares same-day outpatient discharge to standard inpatient hospitalization for patients with intra-operatively confirmed gangrenous appendicitis. Eligible participants are adolescents and adults over 14 who meet criteria for outpatient discharge and can give informed consent, while patients with generalized purulent or faecaloid peritonitis, abscess, need for drains, immunosuppression, pregnancy, or inability to follow up are excluded. Outcomes include safety measures (postoperative complications and readmissions), recovery markers (oral tolerance, return to activities), and efficiency metrics (length of stay and resource use) over a defined postoperative follow-up period. Randomization occurs after emergency appendectomy once gangrenous appendicitis is confirmed during surgery.
Why it matters
Potential benefit: If successful, the approach could shorten hospital stays, reduce healthcare costs, and allow suitable patients to recover at home sooner.
How similar studies have gone: Same-day discharge after uncomplicated appendectomy has been shown to be safe in other studies, but outpatient management specifically for gangrenous appendicitis has been less well studied.
