Study summary

This study aims to evaluate the utility of double-ring wound-edge protectors to prevent the development of superficial surgical site infections after open appendectomy.

Read the detailed description

This is a multi-centric retrospective study comparing patients of similar characteristics with diagnosis of acute appendicitis that have been treated either by open appendectomy using a double-ring wound-edge protector or by laparoscopic appendectomy between January 2011 and December 2016 at Hospital Recoletas Campo Grande de Valladolid and Hospital Comarcal de Medina del Campo.

The main objective of the study is to compare the incidence of superficial surgical site infection in both groups.

All patients included in the study must meet inclusion criteria and all data will be collected anonymously in order to comply with local law on personal data protection (Organic Law 15/1999 from 13 December about personal data protection).

The authors of the study expect results of the study to be comparable with those in current literature regarding surgical site infections, hospital stay and procedure safety.

Inclusion criteria

  • Age of at least 15 years old.
  • Clinical diagnosis of acute appendicitis.
  • Treated by: Open appendectomy + double-ring wound-edge protector or Laparoscopic appendectomy.
  • Note: with the aim of avoiding selection bias, all patients presenting risk factors for surgical site infections (eg obesity, diabetes, malnourishment, immunosupression, etc.) will be included in the present study.

Exclusion criteria

Exclusion Criteria:

  • Patients who did not receive prophylactic antibiotic.
  • Source of abdominal pathology other than the caecal appendix.
  • Follow-up period less than 30 days.

What researchers measure

Primary outcomes

  1. Superficial surgical site infection (sSSI)

    To compare the incidence of sSSI in both groups (OA+2RWEP versus LA) during postoperative period to determine wether 2RWEP are useful in reducing sSSI after open appendectomy.

    Time frame: 30 days after surgery

Secondary outcomes

  1. Organ-space surgical site infection (oeSSI)

    To compare the incidence of oeSSI in both groups (OA+2RWEP versus LA) during postoperative period to determine wether 2RWEP are useful in reducing oeSSI after open appendectomy.

    Time frame: 30 days

  2. Hospital stay

    To compare the length of hospital stay in both groups (OA+2RWEP versus LA) to determine wether 2RWEP are useful in reducing hospital stay.

    Time frame: 30 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.
No changes since tracking began. The registry record was last updated on Dec 7, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
