Design outcomes

Primary

MeasureTime frame
Primary Variable: The extent of postoperative adhesions, assessed via ultrasound by a radiologist blinded to the patient’s group assignment, 3 to 6 months after surgery.Two outcomes are evaluated:1. A score is assigned based on the extent and severity of adhesions.2. Mobility assessment: The degree of freedom of movement of the ovaries and pelvic organs is examined. Timepoint: Ultrasound 3 to 6 months after gel injection. Method of measurement: ultrasound.

Secondary

MeasureTime frame
Section 4: Study Outcome Variables4-1. Primary Outcome:The primary outcome is the main variable used to answer the research question and estimate the sample size.· Description: Incidence (occurrence) of new or recurrent pelvic adhesions after surgery.· Method and Timing of Measurement: This outcome will be assessed during the planned "second-look" laparoscopy, scheduled 4 to 5 months after the initial surgery.· Assessment Tool/System: Adhesion assessment will be performed by a blinded evaluator using a standardized pelvic adhesion scoring system. The most validated systems for this purpose include the following, which must be specified in the final protocol: · The revised American Fertility Society (r-AFS) adhesion scoring system (the adhesion component). · A dedicated Adhesion Scoring System (e.g., Modified Adhesion Scoring System).· Outcome Measure: Comparison of the mean (or median) adhesion score and the percentage of patients with no new adhesions between the intervention and control groups.4-2. Secondary Outcomes:Secondary outcomes measure complementary important results or side effects of the intervention.1. Pelvic Pain Severity: · Description: Change in the severity of endometriosis-related pain after surgery. · Method and Timing of Measurement: Using the Visual Analogue Scale (VAS) for pain from 0 (no pain) to 10 (worst pain imaginable). This assessment will be conducted preoperatively, 1 month postoperatively, and at the time of the second-look laparoscopy (4-5 months). · Outcome Measure: Comparison of changes in pain scores between the two groups over time.2. Health-Related Quality of Life: · Description: Change in the quality of life of patients with endometriosis. · Method and Timing of Measurement: Using a standardized endometriosis-specific quality of life questionnaire, preferably the Endometriosis Health Profile-30 (EHP-30) or its short version EHP-5. This assessment will be conducted preoperatively and 4-5 months postoperatively (concur
