Treatments of Pelvic Pain Due to Endometriosis with GnRH Agonists Followed by Add-Back Therapy
Transdermal estradiol patch: 25 µg/day, plus medroxyprogesterone acetate 2.5 mg daily This regimen does not completely prevent bone loss. The estradiol concentration achieved is in the range of 30 pg/mL. (Howell, 1995)

Norethindrone acetate 5 mg/day This is a very high dose of progestin. This dose of progestin is associated with a decrease in HDL-cholesterol (Hornstein, 1997)

Conjugated equine estrogen mg/day, norethindrone acetate 5 mg/day This regimen prevents bone loss and markedly reduces the vasomotor symptoms reported. Pain relief was excellent. (Hornstein, 1997)

ADHESIONS

Adhesions causing small bowel obstruction.

PATHOGENESIS Peritoneal Trauma Mechanical trauma
Thermal, electrical or chemical trauma Foreign bodies Infection Inflammation Ischemia After a localized trauma to the peritoneum, the mesothelial cells die and degenerate, leaving a denuded area. The border of this damaged site contains dying cells, as shown on the slide. The process of re-epithelialization is initiated by the local production of chemotactic messengers that arise in conjunction with coagulation.

Initial Stage of Peritoneal Healing
PATHOGENESIS Initial Stage of Peritoneal Healing Chemotactic messengers Coagulation Inflammatory exudate Fibroblast proliferation Healing of the peritoneum occurs primarily by re-epithelization of the damaged site. New peritoneal cells are attracted to the site of injury by chemotactic messengers released by platelets, blood clots, or leukocytes within the injured tissue. At this point, healing of the peritoneum differs from that seen with skin. With skin, healing occurs by granulation at the periphery of the injury. As a result, the duration of healing directly correlates with the size of the injury. Larger injuries take longer to heal than smaller ones. In contrast, re-epithelization of peritoneal injuries occurs by the formation of multiple "islands" of new mesolethial cells scattered upon the surface of the peritoneum. The source of these epithelial cells is controversial and includes adjacent normal mesothelial cells and subperitoneal stem cells. The mesothelial cells in each island continue to divide until the surface of the entire site of injury is covered by a new mesothelium.

Formation of Fibrin Bands
PATHOGENESIS Formation of Fibrin Bands Inflammatory exudate Fibrin deposition Fibrin band formation After trauma to the peritoneum, there is increased vascular permeability, mediated by histamine, which often produces an inflammatory exudate and the formation of a fibrin matrix. Frequently, this fibrin matrix interconnects two adjacent pelvic structures leading to the formation of fibrin bands. These fibrin bands are usually resolved by finbrinolysis, converting the large fibrin molecules into small fibrin-spilt products that are readily removed from the peritoneal cavity.

PATHOGENESIS Fibrinolysis Fibrin Plasminogen Fibrin Split Products
tPA Plasminogen PAI1 and PAI2 Fibrinolysis is a system for removal of fibrin from the peritoneal cavity. The peritoneal cells (mesothelial cells) contain plasminogen which is converted to the active enzyme, plasmin. The plasmin breaks down the fibrin into the biologically inactive fibrin split products by the tissue plasminogen activator pathway (tPA). The fibrinolytic system is modulated by plasminogen inhibitors (PAI1 and PAI2) which may regulate individual differences in fibrin removal. Inhibition Fibrin Split Products

Fully Healed Peritoneum
PATHOGENESIS Fully Healed Peritoneum Fibrinolytic activity Tissue plasminogen activator 5-7 days normal surface healing Under normal conditions, where fibrinolytic activity occurs, mesothelial cell proliferation results in re-epithelialized of the injured site. The surface of peritoneal injuries is typically re-epithelialized 5 to 7 days after surgical injury. Beneath the surface, remodeling of collagen and other connective tissues continues for a few months.

Increased Vascular Permeability Normal Peritoneal Healing
PATHOGENESIS Peritoneal Healing (approximately 5-7 days) Peritoneal Injury Increased Vascular Permeability Inflammatory Exudate Fibrin Deposition Ischemia This slide shows the steps that occur after the peritoneum is injured. Injuries to the peritoneal surface can cause stimulation of mast cells, resulting in the release of histamine and vasoactive kinins. These substances cause an increase in capillary permeability that leads to the formation of an inflammatory exudate that, in turn, results in deposition of fibrin. Fibrinolysis is vital to the removal of this fibrin deposit. Under ischemic conditions that result from peritoneal injury, the tissue loses its abundant fibrinolytic activity. The fibrin is allowed to persist as re-epithelization occurs. The fibrin becomes covered with a mesolethial surface and, in some cases, actually undergoes endothelial cell migration and neovascularization. This process leads to adhesions. Adhesion formation, therefore, requires both raw surface areas weeping fibrin exudate, as well as the failure to remove fibrin by fibrinolysis. Fibrinolysis Suppressed Fibrinolysis Fibrin Fixation Normal Peritoneal Healing Adhesion Formation

PATHOGENESIS Adhesion Formation Fibroblast proliferation
Mesothelial over-growth Neovascularization Under the ischemic conditions present after surgical trauma, fibrinolytic activity is suppressed, which results in persistence of fibrin bands. Once the fibrin bands are infiltrated with fibroblasts, they become organized to form what are clinically identified as adhesions. It is important to note that healing of the peritoneal surface is not complete for about 5 to 7 days. Deposition of fibrin actually begins during the surgical procedure. Thus, adhesions can form at any time during this healing period.

Adhesions Following Reproductive Pelvic Surgery by Laparotomy
INCIDENCE Adhesions Following Reproductive Pelvic Surgery by Laparotomy Study Year N % with adhesions Diamond et al % DeCherney and Mezer % Surrey and Friedman % Pittaway et al % Trimbos-Kemper et al % Daneill and Pittaway % TOTAL % The incidence of pelvic adhesions varies following pelvic reconstructive surgery. The table above provides an overview of the studies reviewed by Diamond. Diamond et al noted an 86% incidence of pelvic adhesions at second-look laparoscopy after reconstructive pelvic surgery. DeCherney and Mezer observed a 75% incidence of adhesions after the initial procedures at 4-16 weeks. Surrey and Friedman noted a 71% incidence of adhesion formation. When a subset of these patients was studied long-term, 83% of them had adhesions. Pittaway et al found that all 23 of their patients had adhesions. Trimbos-Kemper et al observed adhesions in 55% of their patients. Finally, Daniell and Pittaway noted adhesion formation in 96% of women at second-look laparoscopy following conservative surgery. It is important to note that the adhesions seen in these studies represent not only adhesion reformation, but de novo adhesions as well. Majority of second-look laparoscopy performed between 1-12 weeks Adapted from Diamond M.P. Obstet Gynecol, 1988.

Incidence Ovary (55%) Pelvic sidewall (40%) Fimbria (36%)
Omentum (19%) Small Intestine (15%) Colon (15%)

INCIDENCE Adhesions Following Laparoscopy Procedure N % with adhesions

Clinical Consequences of Adhesions
COMPLICATIONS Clinical Consequences of Adhesions Infertility Chronic pelvic pain (CPP) Small bowel obstruction (SBO) Intraoperative complications Subsequent surgery There are many different complications associated with post-surgical adhesions. Among the most common are infertility, chronic pelvic pain, pelvic pain, and small bowel obstruction.

Chronic Pelvic Pain: Laparoscopic Findings
COMPLICATIONS Chronic Pelvic Pain: Laparoscopic Findings This chart demonstrates that adhesions were present in 15% - 45% of the patients suffering from chronic pelvic pain.

Chronic Pelvic Pain Relief after Laparoscopic Adhesiolysis
COMPLICATIONS Chronic Pelvic Pain Relief after Laparoscopic Adhesiolysis Chronic pelvic pain in patients with associated intrapelvic adhesive disease is usually reduced after adhesiolysis indicating that adhesions often cause pelvic pain. It is as difficult to confirm that adhesions cause chronic pelvic pain as it is to confirm that adhesiolysis relieves chronic pelvic pain. Investigative reports found that adhesiolysis relieved the pain in approximately 60% to 90% of the patients. Howard, FM. Obstet Gynecol Surv 1993;48:

Recurrence of Pain Following Adhesiolysis
COMPLICATIONS Recurrence of Pain Following Adhesiolysis Pain Rating Although most patients with chronic pelvic pain and adhesions experience a decrease in pain during the first few weeks after adhesiolysis, many note a recurrence of pain within the first few months following surgery. Time Since Surgery, Months Time of pain return during daily activities after laparoscopic lysis of adhesions. Steege and Stout, Am J Obstet Gynecol, 1991;165:278.

The Paradox of Chronic Pelvic Pain and Adhesions
COMPLICATIONS The Paradox of Chronic Pelvic Pain and Adhesions Pelvic adhesions present in 15% - 45% of patients with chronic pelvic pain Adhesions may or may not be the cause of chronic pelvic pain Adhesiolysis decreases pain or is beneficial in a large percentage of patients??? Many patients have recurrence of pain or increased pain over time There is much controversy when trying to correlate chronic pelvic pain and adhesion formation. It has been reported that adhesions were present in 15-45% of patients suffering chronic pelvic pain. However, some patients who have adhesions have no pelvic pain and some patients who have pelvic pain do not have adhesions. While adhesiolysis decreases CPP in a large percentage of patients, many experience a recurrence of, or increase in, pain over time. Howard F.M. Obstet Gynecol Surv 1993;48:

Surgical Techniques to Minimize Adhesions
ADHESION PREVENTION Surgical Techniques to Minimize Adhesions Directed hemostasis Avoid: ischemia desiccation sponging tissue grafts introduction of foreign bodies Minimize tissue handling Use fine non-reactive sutures placed without tension Consider using heparin in irrigation fluid The following steps can be taken during surgery to minimize the incidence of adhesions: 1) Achieve directed hemostasis: Inadequate hemostasis and the resultant fibrin deposition promote adhesion formation. 2) Avoid ischemia, drying of tissues, the use of gauze or dry sponging, tissue grafts and the introduction of foreign bodies, such as talc. 3) Minimize tissue handling: Manipulating tissue increases the possibility of vascular and tissue damage. When direct manipulation of the peritoneum is necessary, use either traumatic instruments or fingers. In addition, cutting and coagulating should be kept to a minimum to reduce the possibility of trauma and maintain vascularity. 4) Use fine, non-reactive sutures: To minimize foreign body reactions, use the smallest size suture composed of synthetic material. 5) Frequent peritoneal irrigation throughout the surgical procedure with a crystalloid solution containing a buffering capacity (i.e., lactated Ringer’s solution) with an anti-coagulant, such as Heparin, may rinse away some fibrinous exudates and, if suctioned out of the pelvic cavity, may reduce formation of adhesions; however, no data support the effectiveness of Heparin to prevent adhesion formation in humans.

Controlled Clinical Trials
ADHESION PREVENTION Controlled Clinical Trials Non-efficacious Efficacious Dextran 70 Interceed* (TC7) Absorbable Ibuprofen Adhesion Barrier Tolmetin Preclude** Surgical Membrane Cortisone Seprafilm*** Bioresorbable Membrane Gynecare Intergel Dextran and other high molecular weight fluids have been instilled into the peritoneal cavity to "float" the organs but they have not shown a significant reduction in adhesion formation. Ibuprofen and Tolmetin have also been shown to be non-efficacious due to rapid absorption from the peritoneal cavity. A number of studies, however, demonstrate that the use of barriers is an effective method to prevent adhesion formation. *Trademark of ETHICON, Inc. **Trademark of W.L.
