Abstract
The study investigated the impact of gonadotropin-releasing hormone analogue (GnRH-a) on coagulation and fibrinolytic activities and its effectiveness in the prevention of pelvic adhesion after myomectomy. Thirty-two infertile women underwent myomectomy followed by adhesion evaluation surgery with a second-look laparoscopy. Before myomectomy, 15 women were treated with triptorelin acetate for 3 months and 17 received no treatment. Plasminogen activator inhibitor (PAI), thrombin activatable fibrinolysis inhibitor (TAFI), protein C (PC), plasminogen, α2-antiplasmin were determined by enzyme-linked immunosorbent assays and the activity of coagulation factors V and VIII by coagulometric methods. Patients treated with GnRH-a showed significant decrease in PAI, TAFI, factors V, and VIII (P < .05) and increased PC (P < .05), but no significant change in plasminogen and α2-antiplasmin levels compared with control group. The incidence, extent, and severity of adhesions were significantly lower in GnRH-a-treated patients compared with control group (P < .05), suggesting a possible critical role of the GnRH-a therapy in preventing postoperative adhesion development.

Abstract
OBJECTIVE To show the prevention of adhesion formation by placing an absorbable adhesion barrier after intracapsular myomectomy. DESIGN Prospective blinded observational study. SETTING University-affiliated Hospitals. PATIENT(S) Patients ≥ 18 years old with single or multiple uterine fibroids removed by laparoscopic or abdominal intracapsular myomectomy. INTERVENTION(S) A total of 694 women undergoing laparoscopic or abdominal myomectomy were randomized for placement of oxidized regenerated cellulose absorbable adhesion barrier to the uterine incision or for control subjects without barriers. The presence of adhesions was assessed in 546 patients who underwent subsequent surgery. MAIN OUTCOME MEASURE(S) The primary and secondary outcomes of the analysis were the presence and severity of adhesions for four groups: laparotomy with barrier, laparotomy without barrier, laparoscopy with barrier, and laparoscopy without barrier. RESULT(S) There was a higher rate of adhesions in laparotomy without barrier (28.1%) compared with laparoscopy with no barrier (22.6%), followed by laparotomy with barrier (22%) and laparoscopy with barrier (15.9%). Additionally, the type of adhesions were different, filmy and organized were predominant with an adhesion barrier, and cohesive adhesions were more common without an adhesion barrier. CONCLUSION(S) Oxidized regenerated cellulose reduces postsurgical adhesions. Cohesive adhesions reduction was noted in laparoscopy.

Abstract
BACKGROUND Mesothelial cell proliferation and migration play important roles in reducing formation of postoperative peritoneal adhesions. Hepatocyte growth factor (HGF) is a multifunctional cytokine that stimulates proliferation and migration of various cell types, including mesothelial cells. METHODS We investigated the effect of adenovirus-mediated HGF gene expression on the proliferation and migration of mesothelial cells and evaluated its preventive effects on postoperative formation of peritoneal adhesions. Rat mesothelial cells were isolated and characterized by expression of cytokeratin and vimentin. RESULTS Immunohistochemical staining showed that these cells expressed c-Met, the receptor for HGF. Adenoviral-mediated HGF gene transfer into mesothelial cells resulted in high expression of HGF and enhanced migration. To evaluate the preventive effects of adenoviral-mediated HGF gene transfer on the formation of postoperative peritoneal adhesion, we employed a rat model of cecum abrasion-induced adhesion formation in which 80% of the rats developed postoperative peritoneal adhesions. Local application of recombinant adenovirus carrying the HGF gene reduced adhesion formation in 16 of 20 control rats compared with 7 of 20 treated rats in this model. CONCLUSIONS These results suggest that adenoviral-mediated HGF gene transfer may be a novel strategy for preventing postoperative peritoneal adhesions.

Abstract
BACKGROUND The purpose of the present paper was to assess the efficacy of saline, sodium chromoglycate, dexamethasone and aprotinin, in single or in combined use in reducing postoperative pelvic adhesion formation in a rabbit model. METHODS A standard lesion was performed to induce adhesion formation. Forty-five rabbits were divided into nine study groups. Group 1 was the non-treatment group. In group 2, 3 cm(3) of the rabbits' own serum was instilled i.p. In group 3, 5 mg/kg sodium chromoglycate and 3 cm(3) of the rabbits' own serum were administered i.p. The group 4 rabbits were instilled with 5 mg/kg sodium chromoglycate, 3 cm(3) rabbits' own serum and 1 mg/kg dexamethasone i.p. The group 5 rabbits were injected with 5000 units aprotinin i.m. 2 h before operation and 5 mg/kg sodium chromoglycate, 3 cm(3) of rabbit serum, 1 mg dexamethasone and 5000 units aprotinin instilled i.p. In group 6, 3 cm(3) saline was instilled i.p. Groups 7, 8 and 9 were a repeat of groups 4, 5 and 6 with the exception of replacement of the rabbit serum by 3 cm(3) saline. Animals were evaluated for adhesions 10 days after operation. RESULTS Macroscopic adhesion scores of all the groups (2-9) were significantly less than scores of the control group (group 1). The macroscopic adhesion scores of group 9 and group 8 were significantly less compared to that of group 7. CONCLUSION Intraperitoneal instillation of saline and sodium chromoglycate decreased pelvic adhesion formation significantly in a rabbit model. Addition of aprotinin and dexamethasone to these agents gave a further advantage in decreasing pelvic adhesion formation.

Abstract
OBJECTIVE To look for evidence of a fibrinolytic insufficiency as a cause of adhesion formation. DESIGN Retrospective and prospective study. SETTING University medical center. PATIENT(S) Retrospective study: 50 patients undergoing laparoscopy, divided into patients with and without endometriosis. Prospective study: 18 patients undergoing infertility surgery involving a second-look laparoscopy. INTERVENTION(S) During all surgical procedures, adhesions were scored, and peritoneal fluid and plasma were collected. MAIN OUTCOME MEASURE(S) Parameters of the fibrinolytic system were measured to establish a possible relation with the presence and formation of adhesions. RESULT(S) In patients with endometriosis and adhesions, significantly higher peritoneal fluid concentrations were found for plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator (tPA), and plasminogen, compared with patients with endometriosis but without adhesions. In the prospective study, initial peritoneal PAI-1 concentrations correlated significantly with the extent of adhesion formation (r(s) = 0.49) and adhesion-improvement scores (r(s) = -0.52). Also, the change in concentration of tPA and fibrinogen from the initial surgical procedure to the second-look laparoscopy correlated significantly with adhesion-improvement scores (DeltatPA: r(s)= 0.50; Deltafibrinogen: r(s) = -0.64). CONCLUSION(S) This first prospective study in humans adds further weight to the hypothesis that adhesions are caused by an insufficiency in peritoneal fibrinolytic activity. Plasminogen activator inhibitor-1 is a potential marker for the identification of patients at risk for developing adhesions.

Abstract
BACKGROUND The objective of this study was to assess the safety and efficacy of a 0.5% ferric hyaluronate gel, in reducing adhesions in patients undergoing peritoneal cavity surgery by laparotomy, with a planned 'second-look' laparoscopy. METHODS The study was a randomized (by computer-generated schedule), third party blinded, placebo-controlled, parallel-group design conducted at five centres in Europe. Females aged 18-46 years received 300 ml ferric hyaluronate (n = 38) or lactated Ringer's (n = 39) as an intraperitoneal instillate at the completion of surgery. At second-look 6-12 weeks later, the presence of adhesions was evaluated at 24 abdominal sites. RESULTS Patients treated with ferric hyaluronate had significantly fewer adhesions compared with controls. When adhesions formed, they were significantly less extensive and less severe in the treated group. The American Fertility Society score for adnexal adhesions was reduced by 69% in the treatment group compared with controls. The safety profile of ferric hyaluronate-treated patients was comparable with those treated with lactated Ringer's solution. CONCLUSIONS In conclusion, ferric hyaluronate was safe and highly efficacious in reducing the number, severity and extent of adhesions throughout the abdomen following peritoneal cavity surgery.

Abstract
OBJECTIVE To review the events leading to the formation of adhesions, to describe the development of fibrinolytic agents, to review more than a century of research on the use of fibrinolytic agents in adhesion prevention, and to look at future aspects of adhesion prevention. RESULTS A better understanding of the pathogenesis of adhesion formation has resulted in the use of fibrinolytic agents in their prevention. Fibrinolytic agents promote fibrinolytic activity during the early period after peritoneal trauma during which an increased formation of fibrin is seen in combination with a deficiency of endogenous fibrinolytic activity. Initially, chemical attacks on fibrin (fibrolysin and hypertonic glucose), foreign digestive ferments (pepsin, trypsin, and papain), and stimulation of intraperitoneal leukocytosis (amniotic fluid) were used. Development of new thrombolytic agents was soon followed by experiments in animal adhesion models and clinical studies to examine their antiadhesion properties. Plasmin preparations (plasmin, actase, and fibrinolysin) and plasmin activators (streptokinase, urokinase, and tissue-type plasminogen activator) were found to be efficacious in preventing adhesion formation in the greater part of reviewed animal and clinical studies. CONCLUSION(S) From the current literature, it can be concluded that postoperative intraperitoneal administration of thrombolytic agents can significantly decrease adhesion formation. Given the large number of experimental studies in animals, future studies should focus on the clinical use of fibrinolytic agents in the prevention of postsurgical adhesion formation.

Abstract
OBJECTIVE To determine whether surgical trauma to one or both contacting peritoneal surfaces is necessary to cause coalescing adhesions. SETTING Research laboratory. DESIGN The abdominal wall peritoneum and one or both contacting medial peritoneal surfaces of surgically approximated uterine horns in mice were injured by electrocautery, cutting, scratching, or scraping. Adhesion formation was assessed visually and histologically 3 and 7 days later. RESULTS Regardless of the type of peritoneal injury, few adhesions resulted when only a single injury was made to the abdominal wall (< or = 6%) or to one uterine horn (< or = 13%). When both opposing uterine surfaces were injured, however, adhesions formed at 57% of the sites after electrocautery, 100% after cutting, 100% after scratching, but 0% after scraping. When previously created uterine adhesions were lysed, they reformed at 15 of 15 sites with and 12 of 13 (92%) sites without electrocautery for hemostasis at the time of lysis. CONCLUSIONS In this murine model, the development of postsurgical adhesions required surgical trauma to both contacting peritoneal sites, regardless of the type of injury, the mobility of the opposing peritoneal surfaces or whether hemostasis was achieved. The clinical implications are that more attention needs to be focused on protecting contacting normal peritoneal surfaces from inadvertent injury during surgery and that different therapeutic strategies may be required for prevention of adhesion formation and reformation because of the high probability of contact between injured peritoneal surfaces with the latter.

Abstract
OBJECTIVE To evaluate the ability of the two currently available surgical barriers, oxidized regenerated cellulose and expanded-polytetrafluoroethylene (PTFE), to prevent postsurgical adhesions. DESIGN Murine uterine horns were approximated in the midline and the contacting uterine surfaces injured by electrocautery, cutting, and scratching, with and without barriers interposed. Sham-operated and experimental animals had adhesions assessed visually and histologically 7 days postoperatively. In another group, adhesions were created and then lysed 7 days later with barriers interposed. Readhesion formation was assessed 14 days after lysis with the PTFE being removed 7 days after lysis. SETTING Research laboratory RESULTS Adhesions occurred at 58.5% of the electrocautery sites without barriers, 100% of the readhesion sites with recautery for hemostasis, and 92% of the recautery sites without hemostasis. None of the sham-operated sites developed adhesions. When oxidized regenerated cellulose was interposed, adhesions were observed at 36% of uninjured uterine horn sites, 62% with single and 92% with double electrocautery injuries and 90% of the reformation sites. The PTFE did not cause adhesions in uninjured controls and completely prevented adhesion formation and reformation, regardless of the type of injury or whether hemostasis was achieved. A thin cellular membrane, continuous with the uterine serosa, enveloped the PTFE. CONCLUSIONS Expanded-polytetrafluoroethylene, but not oxidized regenerated cellulose, prevents adhesion formation and reformation in this murine uterine horn model. Additionally, oxidized regenerated cellulose was adhesiogenic even without surgical injury.

Abstract
OBJECTIVE To evaluate the fertility outcome after laparoscopic surgery for ectopic pregnancy. DESIGN A randomized trial versus laparotomy was performed between May 1987 and June 1989. SETTING The study was conducted in a clinical university center, the Sahlgrens Hospital. PATIENTS A group of 105 patients with tubal pregnancy were stratified with regard to risk determinants and age and randomized to laparoscopy or laparotomy. Eighty-seven patients who desired pregnancy were evaluated for subsequent fertility outcome. INTERVENTIONS Linear salpingotomy was performed in both surgical groups. MAIN OUTCOME MEASURE We evaluated the fertility outcome after laparoscopic salpingotomy for comparison with the outcome after laparotomy. RESULTS There was no difference between the groups in the overall fertility outcome. A substantially higher proportion of patients in the laparotomy group were subjected to adhesiolysis performed at a second-look laparoscopy. CONCLUSIONS The fertility prospects are not impaired by laparoscopic surgery. Adhesiolysis at a second-look laparoscopy, especially after laparotomy, might be beneficial in selected cases and may serve to improve subsequent fertility.

Abstract
OBJECTIVES The null hypothesis of this retrospective literature analysis was that the superiority of laparoscopy over laparotomy to correct infertility resulting from tubal injury has not been proved because of the lack of well-designed comparative studies. The same was true for the correction of infertility caused by minimal and mild endometriosis. STUDY DESIGN A retrospective review of the English-language literature since 1975 was made to ascertain whether laparoscopic surgical correction of infertility caused by tubal injury and endometriosis resulted in an increased pregnancy rate compared with laparotomy techniques. Complication rates associated with laparoscopy versus laparotomy were also compared. RESULTS There were almost no adequate studies designed and executed to answer these questions based on criteria established by the United States Preventive Services Task Force. Furthermore, there was no evidence in the reported series that laparoscopic surgical procedures were superior to laparotomy in correcting infertility. The complication rates were similar. There was suggestive, but not yet proven, evidence that laparoscopic surgery with laser techniques may be superior to laparotomy in the management of infertility resulting from moderate and severe endometriosis. CONCLUSION Although results and complications were similar, the cost in savings with respect to decreased hospital expenses and loss of work time favor the use of laparoscopy over laparotomy when results are similar and not associated with increased risk. What has not been established are costs and work-time losses for minilaparotomy compared with laparoscopy.

Abstract
STUDY OBJECTIVE To evaluate the impact of the materials contained in the available adhesion prevention barriers on the peritoneum. STUDY DESIGN, SETTING, PATIENTS: A murine paradigm was used, placing oxidized-regenerated cellulose (Interceed [TC7]) and expanded polytetrafluoroethylene (PTFE; Gore-Tex Surgical Membrane) in the peritoneal cavity for intervals up to 14 days. INTERVENTIONS AND MAIN OUTCOME MEASURES The appearance of the peritoneum on scanning and transmission electron microscopy and the presence of de novo adhesions were the end-points used. RESULTS Oxidized-regenerated cellulose caused localized sloughing of the mesothelial cell layer and leukocyte infiltration of the deeper tissue leading to the formation of adhesions to the bowel and liver in 58% of the animals. The surface of the oxidized-regenerated cellulose-injured peritoneum healed in 5 to 7 days. Neither peritoneal injury nor adhesions were noted in sham-operated animals or animals with PTFE. CONCLUSIONS Oxidized-regenerated cellulose but not PTFE has a localized injurious effect on the peritoneum of the mouse, resulting in de novo adhesions. The impact of the barrier material itself on normal peritoneum may be an important consideration in designing surgical barriers for the prevention of postoperative adhesions.

Abstract
OBJECTIVE Women with ectopic pregnancy (EP) who have been operated on by laparoscopy are thought to have improved subsequent fertility, probably because of less adhesion formation. We aimed to evaluate the adhesion formation after laparoscopy as compared with laparotomy in a randomized trial. DESIGN One hundred five patients with tubal pregnancy were stratified with regard to age and risk factors and randomized to surgery by laparoscopy or laparotomy. To evaluate adhesion formation and tubal status, 73 patients with strong desire of pregnancy underwent a second-look laparoscopy. The adhesion status at the ipsilateral and contralateral side at primary surgery was compared with the status at second-look laparoscopy. RESULTS Patients operated on by laparotomy developed significantly more adhesions at the operated side than patients operated on by laparoscopy (P less than 0.001). Substantially more patients in the laparotomy group underwent adhesiolysis at second-look laparoscopy than did patients in the laparoscopy group. Tubal patency did not differ between the groups. CONCLUSIONS Laparoscopic treatment of EP results in less impairment of the pelvic status compared with conventional conservative surgery.

Abstract
After initial videolaseroscopy for the treatment of endometriosis-associated infertility, 157 patients underwent a second-look laparoscopy to evaluate and treat recurrence of disease and/or adhesions. The patients were divided into two groups. Group 1 consisted of 135 patients who underwent second-look laparoscopy for persistent infertility and/or recurrence of pain. Group 2 consisted of 22 patients who achieved pregnancy after initial surgery and underwent second-look laparoscopy for evaluation of ectopic pregnancy or in association with uterine evacuation for first trimester spontaneous abortion. Both groups of patients demonstrated a significant reduction in adhesion scores involving the ovaries, tubes, posterior cul-de-sac, anterior cul-de-sac, and omentum/bowel. Although the initial mean adhesion scores were similar for both groups, at second-look laparoscopy the mean adhesion scores were significantly lower for group 2, particularly for ovarian and tubal adhesions. None of the patients formed de novo adhesions. From these results we may conclude that videolaseroscopy: (1) is effective in reducing peritoneal adhesions; (2) is associated with a low frequency of postoperative adhesion recurrence; and (3) appears to completely avoid de novo adhesion formation.

Abstract
It has been suggested that the presence of periovarian adhesions might impair the ovarian response to gonadotropins. Periovarian adhesions were recorded in 49 women, and the total percentage of accessible ovarian cortex was described at the initiation of the operative procedure. Adhesiolysis was performed as needed for oocyte recovery. Ovarian access did not correlate with serum estradiol level on either the day of human chorionic gonadotropin (hCG) administration or the day after hCG administration. Similarly, neither the total number of follicles on the day of hCG or on the day after hCG, nor the number of follicles 1.0 to 1.4 cm or greater than or equal to 1.5 cm correlated with ovarian access. We conclude that periovarian adhesions are not a major determinant of the ovarian response to gonadotropin stimulation.

Abstract
Ectopic pregnancy is the shady companion of tubal surgery. Among patients with ectopic pregnancy, relatively few have a history of tubal surgery as their underlying etiologic factor when compared with other etiologies such as PID. Nevertheless, a history of tubal surgery should place the patient at a higher-risk group for ectopic pregnancy; 3% to 20% of these patients will encounter an ectopic pregnancy after the corrective surgery. The incidence of ectopic pregnancy after tubal surgery is extremely variable and is closely linked to the degree of restoration of normal functional and anatomic integrity after the surgical procedure. This depends, to a large extent, on the amount of previous damage to the tube and its potential reversibility. Major improvements in surgical technique can, therefore, have reduced, but not eliminated, the occurrence of tubal pregnancy. The incidence of ectopic pregnancy associated with any given tubal surgical procedure should be taken into consideration when surgery is contemplated. When the risk of ectopic pregnancy is unacceptably high, or when the patient is reluctant to be exposed to a high risk of ectopic pregnancy, IVF-ET could be offered as an alternative. Table 11 represents the incidence of ectopic pregnancy associated with the various surgical procedures. The figures demonstrate the wide variation in outcome for the same procedure.

Abstract
The uterine horns of 30 rats were subjected to both division and microsurgical anastomosis of the proximal segment and division only of the distal segment. They were equally assigned to three groups, of which group 2 received dexamethasone and group 3 received ibuprofen preoperatively and postoperatively for a total of eight doses. During operation, five rats of each group were irrigated with normal saline and the other five, with 32% dextran 70 (Hyskon). The left uterine horn was anastomosed with 7-0 coated Vicryl, and the right horn, with 7-0 Dexon-S sutures. At repeat laparotomy 2 weeks later, the intraperitoneal adhesions were graded blindly according to their severity. Tissue blocks were obtained from the areas of anastomosis and division only for histologic assessment. Total adhesion scores were 104 for group 1, 53 for group 2 (p less than 0.05), and 90 for group 3 (p = 0.7). The histologic evaluation showed no difference between the three groups. The inflammatory tissue reaction was least around the areas of division only and greatest at the anastomotic sites, where it was most pronounced around the surgical knots. No difference in gross adhesions or histologic assessment was observed between the left horn and the right horn. Adhesions were significantly less in the Hyskon-treated animals (p less than 0.05) but the histologic evaluation showed similar inflammatory reactions. These results suggest that in this species there is no difference between Dexon-S and coated Vicryl sutures, that dexamethasone and Hyskon are effective in preventing postoperative adhesions, and that the inflammatory tissue reaction is not altered by these adjuvants but is significantly augmented by the presence and quantity of suture material.

Abstract
Results of tubal reconstructive surgery must be periodically reviewed. This approach permits evaluation of improvements in individual techniques as well as comparison with the results of others performing similar surgery. It also enables meaningful dialogue between physician and patient regarding prospects for success in the physician's own hands. The senior author's experience with 143 cases of tubal reconstructive surgery is presented. Results of four distinct tubal reconstructive procedures are compared with results reported in the available microsurgical and macrosurgical literature. The term pregnancy rate was 45.7% for those who underwent lysis of adhesions, 50.0% among the tubal anastomosis group, and 20.8% among patients treated with a two-stage salpingostomy.

Abstract
In only a few studies of reconstructive surgery for infertility has the importance of periadnexal adhesions been examined with regard to the pregnancy rate. In the present study, 101 patients underwent reconstructive surgery for correction of infertility. Subsequent to surgery, 38.6% of the patients conceived, and 72% of the pregnancies terminated in live births. In analyzing the results, attention was focused upon the correlation between the severity of the periadnexal adhesions and the surgical outcome. By classifying the adhesions into four grades, an inverse relationship was noted between the grade of adhesions and the pregnancy rate. This relationship was consistent regardless of tubal condition, and thus became an important prognostic parameter. In the light of these findings it is felt that, in order to improve the results, more effort should be directed to the prevention of adhesion formation, together with the use of microsurgical technique in this particular field.

Abstract
One hundred and twenty rats were divided into six groups and laparotomized. In three of the groups the cecum was left intact. In one of these groups the cecum was only lifted up through the abdominal incision and then replaced in the abdominal cavity. In another group the intact cecum was bathed with a certain amount of blood from the animal's tail. In the third group the uninjured cecum was covered with fibrinogen in an amount equivalent to that in the blood used in the other group. In the remaining three groups the cecum was traumatized in a standardized way. In one of these groups the injured cecum was left untreated. In another group the traumatized cecum was bathed in homologous blood and in the third group the injured cecum was treated with fibrinogen as described above. Two weeks later the rats were killed and the number and quality of the intra-abdominal adhesions were studied. The findings in the present investigation indicate that neither blood nor fibrinogen per se induced adhesions to the serosa. On the contrary, a defect in the serosa initiated the formation of adhesions.
