Impact of Perioperative Antibiotic Use on Surgical Scarring (PASS)
Perioperative Antibiotic Use and Its Impact on Postoperative Scarring: A Retrospective Study
This retrospective observational cohort study will evaluate whether perioperative antibiotic use is associated with long-term surgical scar outcomes. The study will include adult patients who underwent body surface surgery at Nanfang Hospital between January 1, 2005 and January 1, 2025 and have available surgical, medication, and scar-related clinical records.
The study will not assign participants to any treatment. Researchers will review existing medical records, perioperative antibiotic exposure, surgical characteristics, complications, and scar assessments or photographs. Scar outcomes will be assessed using modified visual analogue scale scores, scar width, scar type, and scar-related complications.

Retrospective Surgical Scar Cohort
Adult patients who underwent body surface surgery at Nanfang Hospital between January 1, 2005 and January 1, 2025 and have available surgical records, perioperative medication records, and scar outcome information.
|
Patterns of perioperative antibiotic use documented in existing medical records, including timing, indication, antibiotic type, duration, frequency, and route of administration.
No antibiotic treatment will be assigned or provided by the study.

Tidsramme |
|---|---|---|
|
Overall Scar Appearance Score Assessed Using a Modified Visual Analogue Scale
Tidsramme: Scar photographs were taken during postoperative clinical follow-up, with an overall range from 3 months to 20 years after surgery. Given the wide span, the assessments will be stratified and reported according to the actual time of photography, for exam
|
Overall scar appearance will be evaluated from scar photographs by three blinded physicians or trained study personnel using a modified visual analogue scale.
Scores range from 1 to 10, with 1 indicating appearance similar to normal skin and 10 indicating the worst imaginable scar appearance.

Scar Width
Tidsramme: Scar photographs were taken during postoperative clinical follow-up, with an overall range from 3 months to 20 years after surgery. Given the wide span, the assessments will be stratified and reported according to the actual time of photography, for exam
|
Scar width will be calculated from scar photographs by outlining the scar boundary and using ImageJ to measure scar area and scar length.
Scar width will be calculated as scar area divided by scar length.

Scar-Related Complications
Tidsramme: Postoperative days 0 to 30 (inclusive). The timing of each complication was determined from medical records.
|
Scar-related complications will be identified from medical records and scar assessments, including wound dehiscence, suture reaction, necrosis, hematoma, infection, persistent itching, persistent pain, and sensory abnormalities.
