Outcome Measures

Primary Outcomes (1)

  • Numerical Pain Intensity Scale (NPIS)

    The Numerical Pain Intensity Scale (NPIS) is a simple, self-reported tool commonly used in clinical settings to assess the intensity of a person's pain. It typically ranges from 0 to 10, with 0 indicating "no pain" and 10 representing "the worst pain imaginable." Patients are asked to rate their pain based on their current experience, providing healthcare professionals with a clear indication of the pain's severity. This scale is useful for tracking pain changes over time, evaluating the effectiveness of treatments, and facilitating communication between patients and providers about pain management. The NPIS is valued for its ease of use and ability to provide quick, quantifiable insights into a patient's pain level.

Study Arms (2)

Group B (Simple compression)

PLACEBO COMPARATOR

In this group, diagnostic laparoscopies commenced with a 5 mm intraumbilical vertical incision, followed by placement of the first bladeless umbilical port trocar (using 5 mm XCEL). Warm CO2 gas insufflation will create the pneumoperitoneum at a flow rate of 1-2.5 L/min; intra-abdominal pressure will be set at 12 mmHg. Patients will then placed in the Trendelenburg position (45°) and the second trocars (using 5 mm XCEL) will be placed at the suprapubic area. Chromopertubation with methylene blue will be performed, with electrocauterization of the endometriotic lesions if necessary. CO2 insufflation will be then ceased and all trocars will be opened. The surgeon will apply abdominal pressure to evacuate any residual CO2. The patient will be then placed in a neutral (horizon plane) position, the trocars will be removed and the incision closed.

Behavioral: simple compression

Group A (Active gas aspiration)

ACTIVE COMPARATOR

Active Gas Aspiration: Once the trocars will be opened, aspiration cannula will be then placed through the accessory port reach at the subdiaphragmatic under direct visualization. After cessation of CO2 insufflation, residual gas will be removed by suctioning with 100 mmHg of pressure until the infra-diaphragmatic area of the abdominal wall close to liver surface. Negative pressure will be then ceased and the aspiration cannula will be taken out under direct vision. The procedure will be completed using the same method as the simple compression group.

Procedure: Group A (Active Aspiration)

Interventions

Once the trocars will be opened, aspiration cannula will be then placed through the accessory port reach at the subdiaphragmatic under direct visualization. After cessation of CO2 insufflation, residual gas will be removed by suctioning with 100 mmHg of pressure until the infra-diaphragmatic area of the abdominal wall close to liver surface. Negative pressure will be then ceased and the aspiration cannula will be taken out under direct vision. The procedure will be completed using the same method as the simple compression group.
