Peritoneal factor and adhesions prevention
Prevention

A) Proper surgical technique :

- Adequate exposure

- Careful hemostasis using bipolar diathermy (pinpoint electrocautery)

- Gentle handling of tissues :

   ·   moist packs and atraumatic instruments

   ·   Irrigation rather than sponging to prevent tissue drying

   ·   When possible, the use of fine-calibre tapered atraumatic needle

- Avoidance of raw surfaces

- Elimination of foreign bodies

Approximation of tissues without tension

- Suture material : Catgut sutures are the most reactive type and should be avoided when possible .

B) Non-barrier method :

1) Peritoneal lavage :

- Frequent irrigation is usually advocated by many surgeons to prevent tissue drying and to wash fibrinous exudate .

- Ringer’s lactae is usually used to prevent acidosis, swelling and associated tissue serosal damage .

- Intraperitoneal antibiotics as cefazolin and tetracyclin are associated with increased adhesions .

2) Intraperitoneal heparin :

- Inhibition of clotting

- Stimulation of plasminogen activator

- Stimulation of of fibroblast growth factor which is an effective stimulator of wound healing

3) Non-steroidal anti-inflammatory :

- Intravenous use of ibuprofen was associated with reduced adhesions formation .

- Intramuscular use has no effect , because absorption is erratic and blood concentrations are inadeqaute at times during mesothelial healing process

- Intraperitoneal use is associated with highly acidic environment which compound pelvis tissue trauma .

4) Corticosteroids :

- Decrease inflammatory response and vascular permeability

- Has a negative impact on wound healing .

- Comtroversial

5) Others controvesial results : progesterone , calcium channel blockers, plasminogen activator .

C) Barrier methods :

1. Dextran :

- A water-soluble glucose polymer

- 32% dextran 70 200 ml is the most widely used

- The mechanism of action is related to hydrofloatation and formation of a siliconizing effect by coating the serosal surfaces

- Side effects include ascites, pleural effusion, coagulopathy and even anaphylactic shock .

2. Oxidized regenerated cellulose barrier (Interceed [TC-7]) :

- The first and the only adhesion prevention adjuvant approved by the FDA .

- It is an oxidized regenrated cellulose in a knitted weave . It differs from Surgigel in the degree of oxidation, porosity , density and weave .

- Following its placement it is converted to into a gelatinous mass that cover the peritoneal and damaged surfaces within 8 hours . It may also facilitate epithelialization .

- Advantages :

a. A biodegradable barrier easy to apply

b. Remains in place without suturing

c. Molded to the anatomical sites

b. Can be applied during laparoscopy

- Disadvantages : injurious effect on the mesothelium resulting in do novo adhesions (contoversial )

- Results : by second look laparoscopy it was found very effective .

3. Gore-Tex surgical membrane :

- Nonreactive and nondegradable expanded polytetrafluoroethylene .

- Disadvantages :

a. It must be sutured in place

b. Requires surgical removal after re-epithelialization , unless left in-situ

- Results : effective in preventing adhesions

4. Sodium carboxymethylcellulose :

- It is heat-stable ,350 Kda poysaccharide

- Its effect is to produce hydrofloatation or a sliliconizing effect and is conocentration and volume dependent

- Results : more effective than 10% dextran 40 and 32% dextran 70

5. Others : Hydrogel polymerization and Polyxamer 407 .
