Study summary

The objective of this trial is to evaluate if intraoperative intraperitoneal administration of fosfomycin, metronidazole and recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) followed by oral antibiotic for three days is as effective as the current intravenous antibiotic treatment given during and three days after appendectomy for perforated appendicitis. The primary outcome is the total length of hospital stay, defined as the number of hours in hospital after end of operation and until 30-day follow-up.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age ≥18 years
  • Suspicion of acute appendicitis and planned for diagnostic laparoscopy and eventual laparoscopic appendectomy
  • Perforated appendicitis (diagnosed during surgery by the surgeon)
  • Negative p-HCG (women)
  • Written after written and verbal information (preoperatively for the intervention group and postoperatively for the control group)

Exclusion criteria

Exclusion Criteria:

  • Cannot understand, read or speak Danish
  • Previous allergic reaction to fosfomycin, metronidazole, rhGM-CSF, or penicillins e.g. piperacillin or amoxicillin
  • Diagnostic laparoscopy revealing normal appendix not requiring an appendectomy or appendicitis without perforation
  • Other intra-abdominal pathology requiring surgical intervention at the same operation
  • Known renal or hepatic disease or biochemical evidence at the time of admission
  • Known hematologic disease in current medical treatment
  • (ASA) physical status ≥4 (a patient with severe systemic disease that is a constant threat to life)
  • Body weight >110 kg
  • Surgery converted to open appendectomy
  • Anticipated compliance problems
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Study arms

  • Experimental
    Intervention group

    Drug: Combination of fosfomycin, metronidazole and rhGM-CSF (administered together intraperitoneally) and three days of antibiotics p.o.

  • Active comparator
    Control group

    Drug: Standard antibiotics intravenously

Interventions

  • DrugCombination of fosfomycin, metronidazole and rhGM-CSF (administered together intraperitoneally) and three days of antibiotics p.o.

    All drugs will be administered together intraperitoneally at the end of the surgery after the appendix has been removed. Hereafter, the intervention group will receive three days of orally administered antibiotics: 500 mg amoxicillin combined with 125 mg clavulanic acid and 500 mg metronidazole. These doses will be administered three times daily.

  • DrugStandard antibiotics intravenously

    4 g piperacillin/500 mg tazobactam and 1 g metronidazole administered intravenously during surgery followed by 4 g piperacillin/500 mg tazobactam and 500 mg metronidazole administered intravenously three times daily for three days.

What researchers measure

Primary outcomes

  1. Total length of hospital stay

    in hours

    Time frame: From end of surgery until 30-days follow-up

Secondary outcomes

  1. Gastrointestinal Quality of Life Index (GIQLI)

    A disease-specific questionnaire validated in Danish is collected at 10 days postoperatively (±2 days) and at 30 days postoperatively (±3 days)

    Time frame: 10 days (±2 days) and 30 days (±3 days) postoperatively

  2. Side effects

    Number and description. A questionnaire regarding side effects is collected within the first 24 hours after surgery and at 10 days postoperatively (±2 days)

    Time frame: Within 24 hours after surgery and 10 days (±2 days) postoperatively

  3. Postoperative complications

    Number. According to the Clavien-Dindo grading

    Time frame: From end of surgery until 30-days follow-up

  4. Surgical site infections requiring surgical drainage

    It is defined as deep incisional surgical site infection according to Centre for Disease Control and Prevention (CDC)

    Time frame: From end of surgery until 30-days follow-up

  5. Intraabdominal abscesses requiring drainage

    Number. It is defined as an organ/space surgical site infection according to CDC

    Time frame: From end of surgery until 30-days follow-up

  6. Readmissions

    Number. Only readmissions related to the surgery will be registered; e.g. admission and treatment of a non-related condition will not be registered.

    Time frame: From end of surgery until 30-days follow-up

  7. Reoperations

    Number. Only reoperations related to the appendectomy will be registered.

    Time frame: From end of surgery until 30-days follow-up

  8. Time to return to normal activities

    Time period in days. The date is defined at the time point at which the participant could return to normal daily activities.

    Time frame: From end of surgery until 30-days follow-up

  9. Period of sick leave "absence from work"

    Time periode in days. The parameter is defined as the number of days from the operation to the time point at where the participant returned to work or school.

    Time frame: From end of surgery until 30-days follow-up

  10. Costs

    The estimated total costs of admission, surgery, possible complications, reoperations etc. in the two treatment groups.

    Time frame: From end of surgery until 30-days follow-up

  11. Adverse events

    Time frame: From end of surgery until 30-days follow-up

  12. Microbiological flora and susceptibility

    Number and type of positive specimens. If participants have a postoperative infectious complication.

    Time frame: From end of surgery until 30-days follow-up

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.
No changes since tracking began. The registry record was last updated on Oct 16, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
