Ovarian Reserve After Laparoscopic Cystectomy for Endometriotic and Non-Endometriotic Cysts

Официальное название

Ovarian Reserve After Laparoscopic Cystectomy for Endometriotic and Non-Endometriotic Cysts: A Comparative Prospective Cohort Study

Обзор

We will conduct this study to estimate the effect of laparoscopic cystectomy on ovarian reserve in endometriotic cysts versus non-endometriotic cysts.

Подробное описание

After eligibility and consenting, all participants aged 18-45 years presented to Benha University or the Endometriosis center with ovarian cyst diagnosed via transvaginal ultrasound or MRI will undergo laparoscopic ovarian cystectomy.

Data will be collected regarding,

1. Baseline clinical data will be collected by healthcare providers including age, BMI, parity, previous pelvic surgery, duration and type of infertility, duration of cyst once diagnosed till time of laparoscopic surgery, laterality of cyst and size. 2. Baseline ovarian reserve will include

* AMH will be measured within 1 month before laparoscopic surgery. * AFC will be measured within 1 month preoperative via transvaginal ultrasound in the early follicular phase of the menstrual cycle (cycle days 2-4). * FSH will be measured within 1 month preoperative between day (2 and 4) of the menstrual cycle. 3. Intraoperative data will be collected by trained operating room nurse including:

* Operative time which is the time lapse between insertion of Veress needle trocar for preparation till the removal of the 10 mm umbilical trocar. * Estimated intraoperative blood loss(mL) where it calculated by

= (Total weight of wet gauze after surgery (g) - Total weight of dry gauze before surgery (g)) + (Amount of fluid in suction bucket (g) - Weight of flushing fluid (g)used) * laterality of the Cyst, number of cauterizations, cyst rupture, adverse effects including soft tissue or organ injury. 4. Postoperative follow up

* Early postoperative follow up with first 24-48 hours during hospital admission recording complications such as fever, intraperitoneal hemorrhage or postoperative pain calculated by NPRS (Numeric Pain Rating Scale) (0-10) where 0 mean no pain and 10 mean intense or intolerable pain or through VAS (Visual Analogue Scale). * Longterm complications will be structurally soliced via telephone calls every 2 weeks till the end of the follow-up period including fever, surgical site infection, readmission or reoperation. * At 3-month postoperative AMH, FSH will be re-evaluated at the same laboratory, and AFC will be re-evaluated by the same ultrasonography.

Вмешательства

• Процедура Laparoscopic Ovarian Cystectomy
  Laparoscopic excision of ovarian cyst under general anesthesia. The procedure includes: (1) CO₂ pneumoperitoneum creation via Veress needle through a 1-cm umbilical incision until intraabdominal pressure reaches 15 mmHg; (2) insertion of a 10-mm umbilical trocar and telescope; (3) placement of two or more 5-mm ancillary trocars under direct visualization; (4) incision of the ovarian capsule using monopolar scissors; (5) identification and careful dissection of the cyst wall from adjacent ovarian
