Factors Influencing Wound Healing After Anal Fistula Surgery

The objective of this observational study is to analyze the factors influencing wound healing after anal fistula surgery and to assess the effectiveness of interventions in improving overall patient outcomes post-surgery. The primary questions this study aims to answer are:

1. Does the use of the growth factor (New Epi) contribute to accelerating wound healing, reducing the risk of infection, and enhancing patient recovery speed after surgery? 2. Do other factors, such as infection, nutritional status, diabetes, surgical methods, patient age and overall health, immune status, and lifestyle habits, affect the healing of surgical wounds?

Treatment and study plan

NewEpi Plus Liquid Wound Dressing

Other
  • Hold the spray nozzle 7-10 cm away from the wound. Apply the product evenly over the wound, with a dosage of one spray (0.1 ml) per 10x10 cm² of wound area.
  • Wait for 2 minutes. It is not necessary to wait until the solution is completely dry; you can proceed with applying ointments and various types of dressings as directed by the physician.
  • Use once a day for 21 days. The frequency of use can be adjusted according to the physician's instructions.

Standard Wound Care

Other

The standard wound care protocol aims to provide comprehensive and systematic care for patients to ensure smooth healing of surgical wounds. These care measures include regular cleaning, disinfection, dressing changes, and continuous observation and assessment of the wound condition. Through strict aseptic techniques and scientific care procedures, standard wound care effectively reduces the risk of infection and promotes wound healing.

Primary outcomes

  1. Wound Healing Speed

    Time frame: Day 7 and Day 21 after surgery

    • Description: Wound healing will be assessed using AI-driven models, such as ResNet and EfficientNet, to track the healing process over time. Healing speed will be reported as the percentage of wound closure per day, based on image analysis.
    • Unit of Measure: Percentage of wound closure per day (%/day)

  2. Postoperative Pain Assessment

    Time frame: 21 days (approximately three weeks of treatment)

    • Description: Pain levels will be assessed using the Visual Analog Scale (VAS), where patients rate their pain on a scale of 0 (no pain) to 10 (worst pain). Higher scores indicate worse outcomes.
    • Unit of Measure: VAS score (0-10)

  3. Daily Painkiller Usage

    Time frame: 21 days (approximately three weeks of treatment)

    • Description: The number of pain relief medications taken by the patient each day will be recorded. This measure will assess the level of pain management required post-surgery. A higher number of painkillers used indicates more pain or less effective pain control.
    • Unit of Measure: Number of painkillers per day

  4. Complication Rate

    Time frame: 21 days (approximately three weeks of treatment)

    • Description: The incidence of complications, such as infection, bleeding, or wound dehiscence, will be tracked. The number of participants experiencing any complications will be reported.
    • Unit of Measure: Number of participants

Secondary outcomes

  1. Number of Participants Who Smoke

    Time frame: At baseline (pre-surgery)

    • Description: Smoking status will be recorded for all participants, categorizing them as current smokers, former smokers, or non-smokers. This will help assess whether smoking affects wound healing outcomes.
    • Unit of Measure: Number of participants

  2. Number of Participants with Alcohol Consumption

    Time frame: At baseline (pre-surgery)

    • Description: Alcohol consumption will be documented, with participants categorized based on their usage patterns (e.g., none, occasional, or frequent use). This measure will examine any correlation between alcohol use and wound healing.
    • Unit of Measure: Number of participants

  3. Dietary Habits

    Time frame: At baseline (pre-surgery)

    • Description:By recording dietary habits (vegetarian or non-vegetarian; dining out or home-cooked meals), we aim to determine whether diet affects the healing of surgical wounds.
    • Unit of Measure: Number of participants

  4. Sleep Patterns

    Time frame: 21 days (approximately three weeks of treatment)

    • Description: By recording sleep times (before 10 PM, 10 PM to midnight, midnight to 2 AM, after 2 AM), we aim to determine whether sleep patterns affect the healing of surgical wounds.
    • Unit of Measure: Number of participants

  5. Nutritional Status

    Time frame: 21 days (approximately three weeks of treatment)

    • Description: Nutritional status will be assessed by tracking recent weight loss (more than 5% after surgry 3 weeks). This will evaluate the potential impact of poor nutrition on wound healing.
    • Unit of Measure: Number of participants

  6. HbA1C Levels to Assess Diabetes Control

    Time frame: 21 days (approximately three weeks of treatment)

    • Description: HbA1C levels will be measured to evaluate diabetes control and its influence on postoperative wound healing.
    • Unit of Measure: HbA1C (%)

  7. BUN levels

    Time frame: At baseline and Day 21 after surgery

    • Description: The study will assess whether blood urea nitrogen (BUN) levels, measured through blood tests, have an impact on wound healing.
    • Unit of Measure: BUN (mg/dL)

  8. eGFR values

    Time frame: At baseline and Day 21 after surgery

    • The study will evaluate whether glomerular filtration rate (eGFR) values, assessed through blood tests, influence wound healing.
    • Unit of Measure: eGFR (mL/min/1.73 m²)

  9. creatinine levels

    Time frame: At baseline and Day 21 after surgery

    • The study will assess whether creatinine levels, evaluated through blood tests, have an impact on wound healing.
    • Unit of Measure: creatinine (mg/dL)

  10. AST (SGOT) levels

    Time frame: At baseline and Day 21 after surgery

    • Description: Liver function will be assessed by measuring AST (SGOT) . This evaluation will help determine whether liver function impacts wound healing.
    • Unit of Measure: U/L

  11. ALT (SGPT) levels

    Time frame: At baseline and Day 21 after surgery

    • Description: Liver function will be assessed by measuring ALT (SGPT) . This evaluation will help determine whether liver function impacts wound healing.
    • Unit of Measure: U/L

  12. Total Bilirubin levels

    Time frame: At baseline and Day 21 after surgery

    • Description: Liver function will be assessed by measuring Total Bilirubin. This evaluation will help determine whether liver function impacts wound healing.
    • Unit of Measure:mg/dL

  13. Direct Bilirubin levels

    Time frame: At baseline and Day 21 after surgery

    1.Description: Liver function will be assessed by measuring Direct Bilirubin. This evaluation will help determine whether liver function impacts wound healing. 2. Unit of Measure:mg/dL
