Summary

A randomized controlled trial was done on 30 women planned for TLH, and divided into two groups; group A includes women that will be subjected to conventional TLH, and group B includes women that will be subjected to TLH with prior uterine artery clipping at its origin. Both grouped will be compared regarding the blood loss, operation time, intraoperative complications and post-operative follow-up

Description

Patients will be randomized into 2 groups:

Group (A): Women who will be subjected to conventional Total laparoscopic hysterectomy Group (B): Women who will be subjected to Total laparoscopic hysterectomy with prior uterine artery clipping at its origin.

Intraoperative

Pre-Anesthesia medications: All patients will receive intravenous antibiotics 30 minutes before induction of anesthesia {Cefotaxime 1gm (Claforan-EIPICO) & Metronidazole 500 mg (Flagyl-rPr)}.

  • All patients will be positioned in the dorsal lithotomy position
  • Examination under anesthesia will be done to assess uterine size, mobility and the presence of any gross adnexal pathology.
  • A bladder catheter will be placed to empty the bladder and to monitor the urine output.
  • A uterine manipulator (V care cup) will be placed through the cervix to manipulate the uterus.
  • The surgeon will stay on the left side of the patient, the assistant on the right side and the scrub nurse in between the patient's legs for uterine manipulation.
  • A small vertical incision will be made into the depth of the supra umbilicus about 0.5 cm length;
  • The closed method will be employed where the Veress needle will be inserted vertically into the supra -umbilical incision.
  • Hanging drop test will be done to ensure proper needle placement through attaching an open syringe filled with saline to the Veress needle and observing the drop.
  • Insertion of 10 mm trocar through the supra umbilical incision and then the operating laparoscope will be inserted through the supra umbilical port.
  • CO2 Insufflation will be started to induce pneumoperitoneum till pressure reached 20 mmHg and reduced to 15 mm afterwards.
  • Two 5 mm lower quadrant ancillary trocars will be inserted lateral to the inferior epigastric arteries under direct laparoscopic vision above the pubic hairline.
  • Another 10 mm trocar will be inserted 3cm above the left lower ancillary trocar under direct vision.

Technical aspects After a thoroughly exploration of the pelvic cavity, the entire abdomen will be surveyed before starting the procedure.

The size of the uterus, presence of myomas, and adnexa and course of ureters will be visualized.

  1. In conventional TLH (control group) :The following will be done 1. -Round ligaments will be coagulated and cut. 2. -Separation of the adnexal structures from the uterine corpus for subsequent preservation or removal:
  2. For salpingo-oophorectomy: the infundibulopelvic ligament will be placed on contralateral traction, awindow will be created in the medial leaf of the broad ligament below the ovarian vessels and ventral to the ureter, maintaining direct visualization of the

ureter.The infundibulopelvic ligament will be coagulated and divided.

2. If preservation of the adnexa will be planned:The fallopian tube and utero-ovarian ligament will be coagulated close to the uterine fundus and detached. The medial leaf of the broad ligament can be incised down to a level just ventral to the pelvic ureter to allow the adnexa to drop out of the field of dissection. The procedure will be repeated on the contralateral side 3. -Dissecting, occluding, and dividing the blood supply prior to extirpation of the uterine corpus:(skeletonization of the uterine vessels at uterine isthmus, coagulation of the vessels, after identification of the ureter) 4. Transection of the cardinal ligament complex with colpotomy and amputation of the cervix from the vaginal apex.

5. Removing the specimen. 6. Laparoscopic closure of the vaginal cuff.

2. In intervention group:

The same steps as in control group but with extra step after coagulation and cutting of the round ligaments. The following steps will be done to reach to the origin of uterine artery from internal iliac artery :

Posterior and medial to the infundibulopelvic ligament, the ureter should be first identified. The surgeon may grab the obliterated umbilical artery at the anterior abdominal wall and retract it. The movement of the umbilical artery may be Seen at the ovarian fossa perpendicular to the ureter.

The peritoneum of the ovarian fossa should be opened above the ureter and over the impression of the umbilical artery. The ureter will be retracted medially and the umbilical artery will be dissected vertical and cranially. Usually, one will identify the origin of the uterine artery at this point, which goes medial to the umbilical artery and almost parallel to the ureter. The uterine vessels will be clipped at their origin from the hypogastric vessels using aclip applier which will be introduced through 10mm trocar. clipping of the artery will be performed through application of two 5 mm size metallic clips in continuity and complete the laparoscopic hysterectomy with the same steps of the conventional method

Postoperative care:

  1. The patient will receive IV fluids in the first 24hours (3litres).
  2. Oral clear fluid intake will be started 8 hours after the operation.
  3. Another dose of antibiotics will be received 6hrs after the operation with the same regimen used in induction.
  4. Postoperative analgesia (NSIDS )
  5. The urinary catheter will be removed after 24hrs after the operation.
  6. CBC will be withdrawn 24hrs after the operation.
  7. Histopathological examination of the specimen will be done.
  8. Vaginal douches and coital activity will be advised against for 3 monthes
