Full conditioning of the peritoneal cavity during laparoscopic surgery will decrease post-operative pain, inflammation and adhesion formation.

Full conditioning will decrease an inflammatory response of the peritoneum and decrease pain and adhesion formation.

Condition Intervention Phase
Endometriosis of the Cul-de-sac Chocolate Cyst of Ovary Fibroid/Myoma (Uterus/Cervix) Procedure: full conditioning Procedure: standard pneumoperitoneum Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Peritoneal Cavity Conditioning During Laparoscopic Surgery Decreases Postoperative Pain, Inflammatory Reaction and Postoperative Adhesions

Further study details as provided by Jasper Verguts, University Hospital, Gasthuisberg:

Primary Outcome Measures:
  • adhesion formation after laparoscopic surgery [ Time Frame: 2 weeks after primary surgery ]
    second look laparoscopy to assess adhesions formed after initial surgery

Secondary Outcome Measures:
  • Post-operative pain [ Time Frame: recorded until 3 days after surgery ]
    pain assessed by VAS scores

  • inflammation [ Time Frame: recorded until 3 days after surgery ]
    bloodsamples to test for C reactive protein and white blood cells

  • time to first flatus and stool [ Time Frame: recorded until 3 days after surgery ]
    patients will be asked when first flatus and first stool appeared. (measured as hours after surgery)

Enrollment: 22
Study Start Date: September 2010
Study Completion Date: December 2013
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Full conditioing
Intervention by alteration of laparoscopic gas with addition of oxygen and nitrous oxide, regulation of humidification and temperature (32°C), injection of 5mg Dexamethasone and application of Hyalobarrier Gel Endo (Nordic Pharma) at the surgical wound
Procedure: full conditioning
addition of 4% oxygen + 10% nitrous oxide to the pneumoperitoneum + humidification + temperature regulation at 32°C
Active Comparator: carbon dioxide
induction pneumoperitoneum with carbon dioxide 100%
Procedure: standard pneumoperitoneum
100% carbon dioxide used for the pneumoperitoenum

Detailed Description:
Randomized controlled trial (RCT) comparing carbon dioxide to full conditioning (addition of oxygen, nitrous oxide, humidification and temperature control, dexamethasone and Hyalobarrier gel) Women undergoing laparoscopy for endometriosis, myomectomy or adhesiolysis will be randomized to either group and will be compared for pain (VAS scores); inflammation (White blood cells, CRP) and adhesions scored by second look laparoscopy.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • women undergoing laparoscopic excision of deep endometriosis (stratum 1), excision of endometrioma's (stratum 2) or excision of uterine myoma's (stratum 3) since this is severe surgery, associated with severe postoperative adhesions and since for most of these women fertility is important and hence the second look laparoscopy can be beneficial.
  • Signed informed consent

Exclusion Criteria:

  • women with a pre-existing condition increasing the risk of surgery such as clotting disorders, heart or lung impairment etc.-Any condition that might interfere with inflammatory parameters such as immunodeficiency, chronic inflammatory disease as Crohn's disease.
  • Pregnancy
  • Conditions associated with chronic pain as peripheral neuropathy, pathology of the vertebral column and osteo-articular disease. Conditions causing acute pain e.g. abdominal trauma
  • a known allergic reaction to Hyalobarrier Gel Endo®
  • A bowel lesion requiring a single or double layer suture. (given that for none of the anti-adhesion barriers safety has been proven following bowel lesions and suture)
