NCT05761080

Brief Summary

To evaluate whether a postoperative therapeutic strategy, Fast Track, aimed at shortening hospital stay in pediatric patients undergoing laparoscopic appendectomy for complicated acute appendicitis, yields outcomes that are not inferior to the standard therapeutic model in terms of the combined variable of adverse events within 30 days postoperatively (including postoperative abdominal abscess, peritonitis, surgical wound complications, reintervention, sepsis, or death).

Outcome Measures

Primary Outcomes (1)

  • Adverse events

    The primary outcome measure will be the composite variable "adverse events" occurring within the first 30 postoperative days, defined as the occurrence of any of the following events: intra-abdominal abscess, peritonitis, surgical wound complications, reoperation, sepsis, or death.

    30 days

Secondary Outcomes (9)

  • Individualized incidence of adverse events

    30 days

  • Hospital readmission rate

    30 days

  • Adverse reactions related to antibiotic treatment

    14 days

  • Need for percutaneous drainage

    30 days

  • Quality of life measure

    day 2, and at 5, 14, and 30 postoperative days

  • +4 more secondary outcomes
