Outcome Measures

Primary Outcomes (1)

  • Postoperative pain score on postoperative day one (abdominal pain)

    Postoperative pain score for abdominal pain on postoperative day one after laparoscopic appendectomy using the Faces Pain Score Revised (FPS-R score), a self-reported pain score using drawn faces with values from 0 (no pain) to 10 (most pain). It is validated for use in studies with children.

    Postoperative day one.

Secondary Outcomes (6)

  • Postoperative pain scores during postoperative phase (abdominal pain)

    Through study completion, an average of 3 days

  • Postoperative pain scores during postoperative phase (shoulder pain)

    Through study completion, an average of 3 days

  • Length of operation

    Intraoperative

  • Length of stay

    Through study completion, an average of 3 days

  • Intra- and postoperative complications

    Through study completion, an average of 3 days

  • +1 more secondary outcomes

Eligibility Criteria

Age5 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Prepped and consented for diagnostic laparoscopy for likely acute appendicitis
  • years or older
  • kg or more
  • Parents/legal custodian give consent, patient shows no signs of unwillingness to participate
  • Patient is hemodynamically stable

You may not qualify if:

  • Clinical signs of four quadrant peritonitis as a clinical sign of perforated appendicitis
  • Suspected perityphlitic abscess on preoperative ultrasound
  • Preexisting conditions making postoperative assessment of extent of pain and its localization very difficult or impossible, e.g. conditions that are associated with pronounced developmental delays or with communication difficulties
  • Parents have inadequate knowledge of German language to understand Informed consent
  • Child has inadequate knowledge of German language to allow elicitation of Pain Scores
