Acta Biomater 2022; 146:80-93. [PMID: 35500814 DOI: 10.1016/j.actbio.2022.04.037] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 04/05/2022] [Accepted: 04/21/2022] [Indexed: 11/01/2022]
Abstract
Postoperative adhesion is a serious and frequent complication, but there is currently no reliable anti-adhesive barrier available due to low tissue adhesiveness, undesirable chemical reactions, and poor operability. To overcome these problems, we report a single-syringe hotmelt tissue adhesive that dissolves upon warming over 40 °C and coheres at 37 °C as a postoperative barrier. Tendon-derived gelatin was conjugated with the ureidopyrimidinone unit to supramolecularly control the sol-gel transition behavior. This functionalization improved bulk mechanical strength, tissue-adhesive properties, and stability under physiological conditions through the augmentation of intermolecular hydrogen bonding by ureidopyrimidinone unit. This biocompatible adhesive prevented postoperative adhesion between cecum and abdominal wall in adhesion models of rats. This hotmelt tissue adhesive has enormous potential to prevent postoperative complications and may contribute to minimally invasive surgery. STATEMENT OF SIGNIFICANCE: There is a strong need to develop medical tissue adhesives with high biocompatibility, tissue adhesiveness, and operatability to prevent postoperative complications. In this report, single syringe, hotmelt-type tissue adhesive was developed by controlling sol-gel transition behavior of gelatin through supramolecular approach. The functionalization of gelatin with quadruple hydrogen bonding improved key features necessary for anti-adhesive barrier including bulk mechanical strength, tissue adhesive property, stability under physiological conditions, and anti-adhesive property. The hotmelt tissue adhesive can be used for a sealant, hemostatic reagent, and wound dressing to prevent postoperative complications including delayed bleeding, perforation, and inflammation and contribute to minimally invasive surgery.

Abstract
The cause of all small bowel obstruction in 60-75% of cases is adhesive development. The first and main method for adhesion prevention is undoubtedly the surgical technique, but the prevention of adhesive development is still actual. We aimed to study macroscopic and microscopic peculiarities of the intestine, peritoneum, and scars of the anterolateral abdominal wall. Also, immunological blood changes were observed in rats with the experimental created adhesive disease on the background of azathioprine introduction. The experiment was conducted on 40 rats divided into 2 subgroups: 20 animals as an experimental group (EG1) and 20 as a control group (CG1). Animals from EG received azathioprine (Moshimerampreparaty named by N.A. Semashko, Russia) in a dosage of 1 mg/100g of weight once a day for the first 3 days (starting from the day of surgery). The control group did not receive any drugs. All 40 rats survived the postoperative period. Rats were removed from the experiment on the 7th day after the operation. There were significant statistical differences in most indicators between the experimental and control groups. Phagocytic index (PI) was reduced by 4.55 due to the natural reaction of the rat organism to the surgery. Indicators of EG were a slight decrease in leukocytes and lymphocytes by 0.3 and 0.9, respectively, a moderate decrease in T-lymphocytes by no more than 2.0, and a decrease in phagocytic activity by 5.8. Immunosuppression with azathioprine significantly reduced the frequency and severity of the adhesive process of the abdominal cavity. Used in the recommended dose does not significantly inhibit important indicators of immunity and does not affect wound healing processes.

Abstract
The development of adhesions after gynecologic surgery is a severe problem with ramifications that go beyond the medical complications patients suffer (which most often include pain, obstruction and infertility), since they also impose a huge financial burden on the health care system and increase the workload of surgeons and all personnel involved in surgical follow-up care. Surgical techniques to avoid adhesion formation have not proven to be sufficient and pharmaceutical approaches for their prevention are even less effective, which means that the use of adhesion prevention devices is essential for achieving decent prophylaxis. This review explores the wide range of adhesion prevention products currently available on the market. Particular emphasis is put on prospective randomized controlled clinical trials that include second-look interventions, as these offer the most solid evidence of efficacy. We focused on adhesion scores, which are the most common way to quantify adhesion formation. This enables a direct comparison of the efficacies of different devices. While the greatest amount of data are available for oxidized regenerated cellulose, the outcomes with this adhesion barrier are mediocre and several studies have shown little efficacy. The best results have been achieved using adhesion barriers based on either modified starch, i.e., 4DryField® PH (PlantTec Medical GmbH, Lüneburg, Germany), or expanded polytetrafluoroethylene, i.e., GoreTex (W.L. Gore & Associates, Inc., Medical Products Division, Flagstaff, AZ), albeit the latter, as a non-resorbable barrier, has a huge disadvantage of having to be surgically removed again. Therefore, 4DryField® PH currently appears to be a promising approach and further studies are recommended.

Abstract
BACKGROUND Adhesions are fibrin bands that are a common consequence of gynaecological surgery. They are caused by conditions that include pelvic inflammatory disease and endometriosis. Adhesions are associated with comorbidities, including pelvic pain, subfertility, and small bowel obstruction. Adhesions also increase the likelihood of further surgery, causing distress and unnecessary expenses. Strategies to prevent adhesion formation include the use of fluid (also called hydroflotation) and gel agents, which aim to prevent healing tissues from touching one another, or drugs, aimed to change an aspect of the healing process, to make adhesions less likely to form. OBJECTIVES To evaluate the effectiveness and safety of fluid and pharmacological agents on rates of pain, live births, and adhesion prevention in women undergoing gynaecological surgery. SEARCH METHODS We searched: the Cochrane Gynaecology and Fertility Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, and Epistemonikos to 22 August 2019. We also checked the reference lists of relevant papers and contacted experts in the field. SELECTION CRITERIA Randomised controlled trials investigating the use of fluid (including gel) and pharmacological agents to prevent adhesions after gynaecological surgery. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane. We assessed the overall quality of the evidence using GRADE methods. Outcomes of interest were pelvic pain; live birth rates; incidence of, mean, and changes in adhesion scores at second look-laparoscopy (SLL); clinical pregnancy, miscarriage, and ectopic pregnancy rates; quality of life at SLL; and adverse events. MAIN RESULTS We included 32 trials (3492 women), and excluded 11. We were unable to include data from nine studies in the statistical analyses, but the findings of these studies were broadly in keeping with the findings of the meta-analyses. Hydroflotation agents versus no hydroflotation agents (10 RCTs) We are uncertain whether hydroflotation agents affected pelvic pain (odds ratio (OR) 1.05, 95% confidence interval (CI) 0.52 to 2.09; one study, 226 women; very low-quality evidence). It is unclear whether hydroflotation agents affected live birth rates (OR 0.67, 95% CI 0.29 to 1.58; two studies, 208 women; low-quality evidence) compared with no treatment. Hydroflotation agents reduced the incidence of adhesions at SLL when compared with no treatment (OR 0.34, 95% CI 0.22 to 0.55, four studies, 566 women; high-quality evidence). The evidence suggests that in women with an 84% chance of having adhesions at SLL with no treatment, using hydroflotation agents would result in 54% to 75% having adhesions. Hydroflotation agents probably made little or no difference to mean adhesion score at SLL (standardised mean difference (SMD) -0.06, 95% CI -0.20 to 0.09; four studies, 722 women; moderate-quality evidence). It is unclear whether hydroflotation agents affected clinical pregnancy rate (OR 0.64, 95% CI 0.36 to 1.14; three studies, 310 women; moderate-quality evidence) compared with no treatment. This suggests that in women with a 26% chance of clinical pregnancy with no treatment, using hydroflotation agents would result in a clinical pregnancy rate of 11% to 28%. No studies reported any adverse events attributable to the intervention. Gel agents versus no treatment (12 RCTs) No studies in this comparison reported pelvic pain or live birth rate. Gel agents reduced the incidence of adhesions at SLL compared with no treatment (OR 0.26, 95% CI 0.12 to 0.57; five studies, 147 women; high-quality evidence). This suggests that in women with an 84% chance of having adhesions at SLL with no treatment, the use of gel agents would result in 39% to 75% having adhesions. It is unclear whether gel agents affected mean adhesion scores at SLL (SMD -0.50, 95% CI -1.09 to 0.09; four studies, 159 women; moderate-quality evidence), or clinical pregnancy rate (OR 0.20, 95% CI 0.02 to 2.02; one study, 30 women; low-quality evidence). No studies in this comparison reported on adverse events attributable to the intervention. Gel agents versus hydroflotation agents when used as an instillant (3 RCTs) No studies in this comparison reported pelvic pain, live birth rate or clinical pregnancy rate. Gel agents probably reduce the incidence of adhesions at SLL when compared with hydroflotation agents (OR 0.50, 95% CI 0.31 to 0.83; three studies, 538 women; moderate-quality evidence). This suggests that in women with a 46% chance of having adhesions at SLL with a hydroflotation agent, the use of gel agents would result in 21% to 41% having adhesions. We are uncertain whether gel agents improved mean adhesion scores at SLL when compared with hydroflotation agents (MD -0.79, 95% CI -0.82 to -0.76; one study, 77 women; very low-quality evidence). No studies in this comparison reported on adverse events attributable to the intervention. Steroids (any route) versus no steroids (4 RCTs) No studies in this comparison reported pelvic pain, incidence of adhesions at SLL or mean adhesion score at SLL. It is unclear whether steroids affected live birth rates compared with no steroids (OR 0.65, 95% CI 0.26 to 1.62; two studies, 223 women; low-quality evidence), or clinical pregnancy rates (OR 1.01, 95% CI 0.66 to 1.55; three studies, 410 women; low-quality evidence). No studies in this comparison reported on adverse events attributable to the intervention. AUTHORS' CONCLUSIONS Gels and hydroflotation agents appear to be effective adhesion prevention agents for use during gynaecological surgery, but we found no evidence indicating that they improve fertility outcomes or pelvic pain, and further research is required in this area. It is also worth noting that for some comparisons, wide confidence intervals crossing the line of no effect meant that clinical harm as a result of interventions could not be excluded. Future studies should measure outcomes in a uniform manner, using the modified American Fertility Society score. Statistical findings should be reported in full. No studies reported any adverse events attributable to intervention.

Abstract
Adhesion is a postoperative complication that has plagued gynecologists for many years, as 60-90% of gynecological patients develop adhesions after abdominopelvic surgeries. Abdominopelvic adhesions could lead to chronic pelvic pain, infertility, intestinal obstruction, and complicated reoperations. Adhesions might also increase the risk of postoperative chemoradiotherapy failure and endanger patients' lives, especially after surgeries for gynecological malignant tumors. The aim of this consensus was to review the pathogenesis and clinical consequences of adhesions and to summarize various surgical procedures and preventive measures that can reduce the occurrence of adhesions after gynecological tumor surgeries based on a discussion among well-known domestic gynecology specialists.

Abstract
Background and Objectives: To compare the efficacy of 3 different techniques for prevention of adhesion reformation after hysteroscopic adhesiolysis in patients with moderate-to-severe intrauterine adhesions. Short-term assisted reproductive outcomes were also compared. Study Design: Total of 72 cases were randomized to Lippes loop intrauterine device (IUD) only, IUD plus a new crosslinked hyaluronan (NCH) gel, or NCH gel only following hysteroscopic adhesiolysis. All cases received hormonal therapy and a second hysteroscopy was carried out. Endometrial thickness values were measured using transvaginal ultrasonography and American Fertility Society adhesion scores were noted during first and second hysteroscopy in all groups. Reproductive outcomes were also compared for those who received in vitro fertilization treatment. Results: Transvaginal ultrasonography revealed significantly better endometrial thickness in the IUD+NCH (7.5 mm) and NCH-only groups (6.5 mm) than the IUD-only group (5 mm) (P < .001). All groups revealed enhanced but comparable American Fertility Society adhesion scores on second-look hysteroscopy. A total of 37 patients received in vitro fertilization treatment after surgical management of adhesions. Ongoing pregnancy rates after in vitro fertilization were 27%, 40%, and 36% in IUD, IUD+NCH, and NCH groups, respectively. However, the difference between the groups did not reach statistically significant difference. Conclusion: All interventions are of similar efficacy in the prevention of adhesion reformation after hysteroscopic adhesiolysis for moderate to severe intrauterine adhesions. However, better endometrial thickness values were observed in those who received NCH gel either alone or in combination with IUD. Assisted reproductive outcomes of both groups were comparable for ongoing pregnancy rates.

Abstract
BACKGROUND The aim of this study is to assess the clinical effectiveness and safety of hyaluronic acid gel for the prevention of postoperative intrauterine adhesions (IUAs). METHODS PubMed, Cochrane Library, Embase and ClinicalTrials.gov databases were searched for randomized controlled trials. RESULTS Six RCTs with a total of 564 patients met the inclusion criteria. The meta-analysis showed that, compared to no other treatment method, hyaluronic acid gel significantly reduced the rate of any IUA (risk ratio [RR] 0.68; 95% CI 0.53-0.86; p = 0.03; I2 = 64%) and adhesion score (standard mean difference = -2.90; 95% CI -4.61 to -1.49; p < 0.00001; I2 = 98%) following intraperitoneal or intrauterine surgery. Treatment lowered the rate of IUAs classified as moderate (RR 0.26; 95% CI 0.13-0.52; p = 0.13; I2 = 0%), but not those deemed mild (RR 0.86; 95% CI 0.62-1.21; p = 0.39; I2 = 3%) or severe (RR 0.33; 95% CI 0.03-3.09; p = 0.33; I2 = 0). Compliance with hyaluronic acid gel treatment was low. CONCLUSION Hyaluronic acid gel can prevent IUAs, particularly those with moderate severity and a lower adhesion score.

Abstract
PURPOSE Uterine myomas are the main cause of benign uterine diseases in premenopausal women. Objective of the present paper is to investigate the current best treatment modalities of myomas, depending on age of the patient and her desire to preserve fertility, as well as on clinical presentation of this pathology, such as size, number, and location of fibroids and, furthermore, on surgical experience of the gynecologist. METHODS The design of our work is a systematic literature review of existing studies, reviews, and meta-analysis conducted in PubMed and Cochrane Library to identify relevant literature. Commonly, the myomectomy is to be recommended in women desiring to preserve fertility when myomas are associated with symptoms such as excessive bleeding, pelvic discomfort, or palpable abdominally fibroids. The decision of surgical approach for myomectomy should be individualized, depending on size and location, as well as on surgeon's experience. The different modalities of myomectomy, laparoscopic, hysteroscopic, robotic-assisted, or laparotomic are in detail presented in the paper, according to Society of Obstetricians and Gynecologists of Canada (SOGC) clinical practice guidelines and taking into consideration possible concerns of myomectomy such as uterine rupture, development of adhesions, and myomas' recurrence.

Abstract
Postoperative adhesion formation is still an important cause of morbidity and mortality. Hydrophilic polyethylene glycol-based adhesion barrier (SprayGel™, Confluent Surgical, Inc., Waltham, MA) is reported to prevent adhesion formation after gynecologic surgery. This study aims to determine the effectiveness of SprayGel™ on adhesion formation after laparotomy in an experimental septic peritonitis model. Wistar albino male rats with weights of 250-350 g were used in this study. Forty rats were grouped into four groups: group I (control), laparotomy and sham operation; group II, laparotomy and cecal ligation puncture (CLP); group III (SprayGel™), laparotomy, sham operation, and SprayGel™; group IV (CLP + SprayGel™), laparotomy, CLP, and SprayGel™. Intra-abdominal sepsis was achieved by perforating the cecum with a 26-gauge needle in selected groups. All animals were sacrificed after 10 days. The results were evaluated according to the score systems of Nair and Knightly. Kruskal-Wallis variance analysis was used for statistical analysis. There were significant differences for the development of adhesion between groups II (CLP) and III-IV (SprayGel™ - CLP + SprayGel™) (p < 0.02). Mortality and wound infection rates were significantly lower in the SprayGel™ treatment groups compared to control groups. Intraperitoneal administration of SprayGel™ significantly decreased the intraperitoneal adhesion formation, and it reduced mortality and wound infection as well.

Abstract
Adhesion formation has been found to be highly prevalent in patients with a history of operations or inflammatory peritoneal processes. These patients are at a high risk of serious intraoperative complications during a subsequent operation if adhesiolysis is performed. These complications include bowel perforation, ureteral or bladder injury, and vascular injury. In order to minimize the risk of these complications, adhesiolysis should only be performed by experienced surgeons, and intraoperative strategies must be adopted. The reduction of the overall incidence of adhesions is essential for subsequent surgical treatments. Anti-adhesion strategies must be adopted for preventing the reoccurrence of adhesions after abdominopelvic operations. The strategies employed to reduce the risk and the overall incidence of adhesions have been elucidated in this article.

Abstract
This study concentrates on the development of biodegradable nanofiber membranes with controlled drug release to ensure reduced tissue adhesion and accelerated healing. Nanofibers of poly(lactic-co-glycolic acid) (PLGA) loaded with epigallocatechin-3-O-gallate (EGCG), the most bioactive polyphenolic compound in green tea, were electrospun. The physicochemical and biomechanical properties of EGCG-releasing PLGA (E-PLGA) nanofiber membranes were characterized by atomic force microscopy, EGCG release and degradation profiles, and tensile testing. In vitro antioxidant activity and hemocompatibility were evaluated by measuring scavenged reactive oxygen species levels and activated partial thromboplastin time, respectively. In vivo antiadhesion efficacy was examined on the rat peritonea with a surgical incision. The average fiber diameter of E-PLGA membranes was approximately 300–500 nm, which was almost similar to that of pure PLGA equivalents. E-PLGA membranes showed sustained EGCG release mediated by controlled diffusion and PLGA degradation over 28 days. EGCG did not adversely affect the tensile strength of PLGA membranes, whereas it significantly decreased the elastic modulus and increased the strain at break. E-PLGA membranes were significantly effective in both scavenging reactive oxygen species and extending activated partial thromboplastin time. Macroscopic observation after 1 week of surgical treatment revealed that the antiadhesion efficacy of E-PLGA nanofiber membranes was significantly superior to those of untreated controls and pure PLGA equivalents, which was comparable to that of a commercial tissue-adhesion barrier. In conclusion, the E-PLGA hybrid nanofiber can be exploited to craft strategies for the prevention of postsurgical adhesions.

Abstract
BACKGROUND Formation of adhesions after peritoneal surgery results in high morbidity. Barriers to prevent adhesion are seldom applied, despite their ability to reduce the severity of adhesion formation. We evaluated the benefits and harms of four adhesion barriers that have been approved for clinical use. METHODS In this systematic review and meta-analysis, we searched PubMed, CENTRAL, and Embase for randomised clinical trials assessing use of oxidised regenerated cellulose, hyaluronate carboxymethylcellulose, icodextrin, or polyethylene glycol in abdominal surgery. Two researchers independently identified reports and extracted data. We compared use of a barrier with no barrier for nine predefined outcomes, graded for clinical relevance. The primary outcome was reoperation for adhesive small bowel obstruction. We assessed systematic error, random error, and design error with the error matrix approach. This study is registered with PROSPERO, number CRD42012003321. FINDINGS Our search returned 1840 results, from which 28 trials (5191 patients) were included in our meta-analysis. The risks of systematic and random errors were low. No trials reported data for the effect of oxidised regenerated cellulose or polyethylene glycol on reoperations for adhesive small bowel obstruction. Oxidised regenerated cellulose reduced the incidence of adhesions (relative risk [RR] 0·51, 95% CI 0·31-0·86). Some evidence suggests that hyaluronate carboxymethylcellulose reduces the incidence of reoperations for adhesive small bowel obstruction (RR 0·49, 95% CI 0·28-0·88). For icodextrin, reoperation for adhesive small bowel obstruction did not differ significantly between groups (RR 0·33, 95% CI 0·03-3·11). No barriers were associated with an increase in serious adverse events. INTERPRETATION Oxidised regenerated cellulose and hyaluronate carboxymethylcellulose can safely reduce clinically relevant consequences of adhesions. FUNDING None.

Abstract
Asherman syndrome is a debatable topic in gynaecological field and there is no clear consensus about management and treatment. It is characterized by variable scarring inside the uterine cavity and it is also cause of menstrual disturbances, infertility and placental abnormalities. The advent of hysteroscopy has revolutionized its diagnosis and management and is therefore considered the most valuable tool in diagnosis and management. The aim of this review is to explore the most recent evidence related to this condition with regards to aetiology, diagnosis management and follow up strategies.

Abstract
PURPOSE Hydrotubation has been considered to be a complimentary procedure to reproductive surgery, usually being conducted after surgery. The objective of this work was to assess the potential value of intra-operative hydrotubation in improving fertility of tubal infertile women. METHODS 180 tubal infertile women were randomly assigned to one of the three groups: intra-operative hydrotubation (IH), post-operative hydrotubation (PH) or control group. In IH group, the hydrotubation was performed immediately after adhesiolysis during the surgery process, while in PH group it was performed within 3-7 days after the first post-operative menstruation. The incidence of post-operative pelvic infection and average hospitalization length were recorded. The post-operative pregnancy outcomes, including intrauterine pregnancy (IUP) rate and incidence of ectopic pregnancy, were recorded at 2 years follow-up. RESULTS No significant difference was found among the three groups, either in the incidence of pelvic infection (P = 0.877) or in the average hospitalization length (P = 0.596). At 2 years of follow-up, the rate of IUP in IH group was significantly higher than that in either PH or control group (P = 0.017 and 0.039, respectively), but no difference was observed between PH and control group (P = 0.752). No significant difference in the incidence of ectopic pregnancy was showed among three groups (P = 0.947). CONCLUSIONS The appropriate use of intra-operative hydrotubation can improve the post-operative IUP rate, serving as a complementary procedure for the surgical treatment of fertility reversal.

Abstract
Adhesions are abnormal fibrous connections, joining tissue surfaces in abnormal locations. Adhesions form after any trauma involving the peritoneum and the injured tissue surface or directly between the injured tissue surfaces. The ideal anti-adhesion agent should be safe, efficacious, easy to use in all types of surgery, and economical. It should prevent adhesions at the site of surgery as well as throughout the peritoneal cavity. Needless to say, the ideal agent is still elusive.

Abstract
INTRODUCTION The formation of peritoneal adhesions still is a relevant clinical problem after abdominal surgery. Until today, the most important clinical strategies for adhesion prevention are accurate surgical technique and the physical separation of traumatized serosal areas. Despite a variety of barriers which are available in clinical use, the optimal material has not yet been found. DISCUSSION Mesothelial cells play a crucial physiological role in friction less gliding of the serosa and the maintenance of anantiadhesive surface. The formation of postoperative adhesions results from a cascade of events and is regulated by various cellular and humoral factors. Therefore, optimization or functionalization of barrier materials by developments interacting with this cascade on a structural or pharmacological level could give an innovative input for future strategies in peritoneal adhesion prevention. For this purpose, the proper understanding of the formal pathogenesis of adhesion formation is essential. Based on the physiology of the serosa and the pathophysiology of adhesion formation, the available barriers in current clinical practice as well as new innovations are discussed in the present review.

Abstract
Background: Over the past decades, our knowledge and understanding of adhesions and adhesion-related complications has increasingly grown and it has become evident that adhesions have significant implications for patients, physicians and the healthcare system. The question arises whether this has resulted in greater awareness of adhesion-related problems among practicing physicians and appropriate patient education on this topic in daily practice. The following article provides a brief overview of the important subject of adhesions, discusses current awareness of adhesions among patients and doctors and addresses the consequences of failure to provide patient education and consent from a medical perspective. Methods: Selective literature searches were conducted in PubMed and the Cochrane Library. A patient information and consent form was developed based on several years' experience and expertise in the field of adhesions. Results: Adhesions are the most common type of complication in abdominopelvic surgery today, with devastating consequences for some patients. Surveys investigating the awareness of adhesions among physicians and patients clearly showed that even well-informed physicians fail to educate their patients adequately. Such failure could potentially lead to successful medical malpractice lawsuits against doctors. Conclusion: Considering their clear clinical impact, adhesions and related consequences should always be discussed with patients preoperatively. A newly developed consent form that specifically addresses adhesion formation may serve to thoroughly educate patients preoperatively and to adequately document the process of doing so.

Abstract
BACKGROUND Adhesive small bowel obstruction (ASBO) is an important cause of hospital admission, is associated with significant morbidity and mortality, and therefore is a substantial burden for healthcare systems worldwide. Icodextrin 4% solution (Adept, Shire Pharmaceuticals, UK) is a high-molecular-weight a-1,4 glucose polymer approved in Europe for use as intraoperative lavage and postoperative instillation to reduce the occurrence of post-surgery intra-abdominal adhesions. The present clinical study aimed to evaluate the safety and effectiveness of icodextrin 4% in decreasing the incidence, extent, and severity of adhesions in patients after abdominal surgery for ASBO. METHODS The study was a single-center prospective, randomized investigation. The study is designed and conducted in compliance with the principles of Good Clinical Practice regulations. Safety and efficacy of icodextrin 4% in the study group are compared to no anti-adhesion treatment in a parallel control group with blinded evaluation of primary endpoints. Primary endpoints are the evaluation of the therapeutic role of icodextrin 4% in reducing ASBO recurrence incidence and the need of laparotomies for ASBO recurrence, as well as adhesion formation (with evaluation of their incidence, extent, and severity). A sum of 181 patients with ASBO and surgical indication to laparotomy were enrolled and randomized in two groups. Patients were submitted to adhesiolysis with bowel resection if required with or without anastomosis. The first group received traditional treatment (control group), whereas the second group was treated with the addition of icodextrin 4% solution before the abdominal closure. RESULTS Ninety-one patients were randomized to have icodextrin 4% solution administered intraperitoneally, and 90 patients were randomized to have the traditional treatment. The two study groups were homogeneous regarding their baseline characteristics. The ASBO recurrence rate was 2.19% (2/91) in the icodextrin groups vs 11.11% (10/90) in the control group after a mean follow-up period of 41.4 months (p < 0.05). No differences were found in the need of laparotomies for ASBO recurrence in the studied groups. The adhesion severity score seems lower in the group treated with the addition of icodextrin (p = n.s.). CONCLUSIONS The data resulting from this RCT showed that the use of icodextrin 4% solution in ASBO is safe and reduces intra-abdominal adhesion formation and the risk of re-obstruction.

Abstract
BACKGROUND Plastic and reconstructive uterus operations are performed in congenital uterine anomalies or benign uterine conditions. Congenital uterine anomalies are relatively rare diseases with various approaches for surgical treatment. Therefore, to address the question of the usefulness of a minimally invasive approach in plastic uterus operations, the most common uterine condition which requires reconstructive surgery, namely myomectomy, is discussed. METHOD Searches were conducted in PubMed and The Cochrane Library to identify relevant literature. FINDINGS Compared with myomectomy by laparotomy and minilaparotomy, laparoscopic myomectomy is associated with improved short-term outcomes. Laparoscopy is further associated with less adhesion formation. Pregnancy rates after myomectomy in symptomatic patients might be higher after laparoscopy than after laparotomy. Although uterine ruptures following laparoscopic myomectomy are described in the literature, it seems to be a rare event. Concerning the recurrence, there is evidence that rates are similar after laparoscopy and laparotomy. CONCLUSION Myomectomy by laparoscopy has several advantages over abdominal myomectomy (by conventional laparotomy and minilaparotomy) and should be the standard procedure. Despite the advantages of laparoscopy, abdominal myomectomy is still a frequently performed procedure. Lack of training in advanced laparoscopic procedures hampers the wide-spread use of laparoscopic myomectomy. Due to the advantages of laparoscopic surgery, efforts should be made to implement this procedure into daily practice. To provide the best care, physicians should offer patients the opportunity of a laparoscopic treatment of myomas.

Abstract
This paper is the second of a two-part publication. The initial paper provided a comprehensive overview of the evidence on adhesions to allow gynaecological surgeons to be best informed on adhesions, their development, impact on patients, health systems and surgical outcomes. There is rising evidence that surgeons can take important steps to reduce the burden of adhesions. In this second paper, we review the various strategies to reduce the impact of adhesions, improve surgical outcomes and provide some practical proposals for action on adhesions. As well as improvements in surgical technique, developments in adhesion-reduction strategies and new agents offer a realistic possibility of reducing adhesion formation and improving outcomes for patients. They should be considered for use particularly in high-risk surgery and in patients with adhesiogenic conditions. Further research into new strategies to prevent adhesions more effectively through an improved surgical environment, new and combination devices and pharmacological agents should be encouraged. Formal recommendations would ensure better prioritisation of adhesion-reduction within the French health system. Patients should also be better informed of the risks of adhesions.

Abstract
Background Adhesions lead to considerable patient morbidity and are a mounting burden on surgeons and the health care system alike. Although adhesion formation is the most frequent complication in abdominal and pelvic surgery, many surgeons are still not aware of the extent of the problem. To provide the best care for their patients, surgeons should consistently inform themselves of anti-adhesion strategies and include these methods in their daily routine. Methods Searches were conducted in PubMed and The Cochrane Library to identify relevant literature. Findings Various complications are associated with adhesion formation, including small bowel obstruction, infertility and chronic pelvic pain. Increasingly, an understanding of adhesion formation as a complex process influenced by many different factors has led to various conceivable anti-adhesion strategies. At present, a number of different anti-adhesion agents are available. Although some agents have proved effective in reducing adhesion formation in randomised controlled trials, none of them can completely prevent adhesion formation. Conclusion To fulfil our duty to provide best possible care for our patients, it is now time to regard adhesions as the most common complication in surgery. Further research is needed to fully understand adhesion formation and to develop new strategies for adhesion prevention. Large clinical efficacy trials of anti-adhesion agents will make it easier for surgeons to decide which agent to use in daily routine.

Abstract
Postoperative adhesions are the most frequent complication of peritoneal surgery, causing small bowel obstruction, female infertility and chronic pain. This pilot study assessed the efficacy of a sprayable polyethylene glycol (PEG) barrier in the prevention of de novo adhesions. 16 patients undergoing laparoscopic gynecological surgery were randomly assigned by shuffled sealed envelopes to receive either the adhesion barrier or no adhesion prevention. Incidence and severity of adhesions were scored at eight sites in the pelvis and reassessed by second look laparoscopy. Adhesion prevention was considered successful if no de novo adhesion were found at second look laparoscopy. One patient was excluded before randomization. Nine patients were randomized to treatment and six patients to control group. De novo adhesions were found in 0/9 patients who received the PEG barrier compared to 4/6 without adhesion prevention (0% vs. 67%, P = 0.01). Reduction in adhesion score was significantly greater in patients receiving PEG barrier (−2.6 vs. −0.06, P = 0.03). Meta-analysis of three randomized trials demonstrated that PEG barrier reduces the incidence of adhesions (odds ratio [OR] = 0.27; 95% CI 0.11–0.67). From this study, PEG barrier seems effective in reducing postoperative formation of de novo adhesions.

Effectiveness of ovarian suspension in preventing post-operative ovarian adhesions in women with pelvic endometriosis: a randomised controlled trial. BMC WOMENS HEALTH 2011; 11:14.

Abstract
Background Endometriosis is a common benign condition, which is characterized by the growth of endometrial-like tissue in ectopic sites outside the uterus. Laparoscopic excision of the disease is frequently carried out for the treatment of severe endometriosis. Pelvic adhesions often develop following surgery and they can compromise the success of treatment. Ovarian suspension (elevating both ovaries to the anterior abdominal wall using a Prolene suture) is a simple procedure which has been used to facilitate ovarian retraction during surgery for severe pelvic endometriosis. The study aims to assess the effect of temporary ovarian suspension following laparoscopic surgery for severe pelvic endometriosis on the prevalence of post-operative ovarian adhesions. Methods A prospective double blind randomised controlled trial for patients with severe pelvic endometriosis requiring extensive laparoscopic dissection with preservation of the uterus and ovaries. Severity of the disease and eligibility for inclusion will be confirmed at surgery. Patients unable to provide written consent, inability to tolerate a transvaginal ultrasound scan, unsuccessful surgeries or suffer complications leading to oophorectomies, bowel injuries or open surgery will be excluded. Both ovaries are routinely suspended to the anterior abdominal wall during surgery. At the end of the operation, each participant will be randomised to having only one ovary suspended post-operatively. A new transabdominal suture will be reinserted to act as a placebo. Both sutures will be cut 36 to 48 hours after surgery before the woman is discharged home. Three months after surgery, all randomised patients will have a transvaginal ultrasound scan to assess for ovarian mobility. Both the patients and the person performing the scan will be blinded to the randomisation process. The primary outcome is the prevalence of ovarian adhesions on ultrasound examination. Secondary outcomes are the presence, intensity and site of post-operative pain. Discussion This controlled trial will provide evidence as to whether temporary ovarian suspension should be included into the routine surgical treatment of women with severe pelvic endometriosis.

Abstract
OBJECTIVE Peritoneal adhesions are almost ubiquitous following surgery. Peritoneal adhesions can lead to bowel obstruction, digestive problems, infertility, and pain, resulting in many hospital readmissions. Many approaches have been used to prevent or treat adhesions, but none offer reliable results. A method that consistently prevented or treated adhesions would benefit many patients. We hypothesized that an anatomically-based visceral mobilization, designed to promote normal mobility of the abdominal contents, could manually lyse and prevent surgically-induced adhesions. MATERIAL AND METHODS Cecal and abdominal wall abrasion was used to induce adhesions in 3 groups of 10 rats (Control, Lysis, and Preventive). All rats were evaluated 7 days following surgery. On postoperative day 7, unsedated rats in the Lysis group were treated using visceral mobilization, consisting of digital palpation, efforts to manually lyse restrictions, and mobilization of their abdominal walls and viscera. This was followed by immediate post-mortem adhesion evaluation. The rats in the Preventive group were treated daily in a similar fashion, starting the day after surgery. Adhesions in the Control rats were evaluated 7 days after surgery without any visceral mobilization. RESULTS The therapist could palpate adhesions between the cecum and other viscera or the abdominal wall. Adhesion severity and number of adhesions were significantly lower in the Preventive group compared to other groups. In the Lysis and Preventive groups there were clear signs of disrupted adhesions. CONCLUSIONS These initial observations support visceral mobilization may have a role in the prevention and treatment of post-operative adhesions.

Abstract
Nasal packs are indispensable in ENT practice. This study reviews current indications, effectiveness and risks of nasal packs and stents. In endoscopic surgery, nasal packs should always have smooth surfaces to minimize mucosal damage, improve wound healing and increase patient comfort. Functional endoscopic endonasal sinus surgery allows the use of modern nasal packs, since pressure is no longer required. So called hemostatic/resorbable materials are a first step in this direction. However, they may lead to adhesions and foreign body reactions in mucosal membranes. Simple occlusion is an effective method for creating a moist milieu for improved wound healing and avoiding dryness. Stenting of the frontal sinus is recommended if surgery fails to produce a wide, physiologically shaped drainage path that is sufficiently covered by intact tissue.

Bologna Guidelines for Diagnosis and Management of Adhesive Small Bowel Obstruction (ASBO): 2010 Evidence-Based Guidelines of the World Society of Emergency Surgery. World J Emerg Surg 2011; 6:5.

Abstract
Background There is no consensus on diagnosis and management of ASBO. Initial conservative management is usually safe, however proper timing for discontinuing non operative treatment is still controversial. Open surgery or laparoscopy are used without standardized indications. Methods A panel of 13 international experts with interest and background in ASBO and peritoneal diseases, participated in a consensus conference during the 1st International Congress of the World Society of Emergency Surgery and 9th Peritoneum and Surgery Society meeting, in Bologna, July 1-3, 2010, for developing evidence-based recommendations for diagnosis and management of ASBO. Whenever was a lack of high-level evidence, the working group formulated guidelines by obtaining consensus. Recommendations In absence of signs of strangulation and history of persistent vomiting or combined CT scan signs (free fluid, mesenteric oedema, small bowel faeces sign, devascularized bowel) patients with partial ASBO can be managed safely with NOM and tube decompression (either with long or NG) should be attempted. These patients are good candidates for Water Soluble Contrast Medium (WSCM) with both diagnostic and therapeutic purposes. The appearance of water-soluble contrast in the colon on X-ray within 24 hours from administration predicts resolution. WSCM may be administered either orally or via NGT (50-150 ml) both immediately at admission or after an initial attempt of conservative treatment of 48 hours. The use of WSCM for ASBO is safe and reduces need for surgery, time to resolution and hospital stay. NOM, in absence of signs of strangulation or peritonitis, can be prolonged up to 72 hours. After 72 hours of NOM without resolution surgery is recommended. Patients treated non-operatively have shorter hospital stay, but higher recurrence rate and shorter time to re-admission, although the risk of new surgically treated episodes of ASBO is unchanged. Risk factors for recurrences are age <40 years and matted adhesions. WSCM does not affect recurrence rates or recurrences needing surgery when compared to traditional conservative treatment. Open surgery is the preferred method for surgical treatment of strangulating ASBO as well as after failed conservative management. In selected patients and with appropriate skills, laparoscopic approach can be attempted using open access technique. Access in the left upper quadrant should be safe. Laparoscopic adhesiolysis should be attempted preferably in case of first episode of SBO and/or anticipated single band. A low threshold for open conversion should be maintained. Peritoneal adhesions should be prevented. Hyaluronic acid-carboxycellulose membrane and icodextrin can reduce incidence of adhesions. Icodextrin may reduce the risk of re-obstruction. HA cannot reduce need of surgery.

Abstract
BACKGROUND Intra-abdominal adhesions arise after more than 50% of all abdominal operations and are an important source of postoperative complications. They attach normally separated organs to each other and can cause major problems for the affected patients by giving rise to small bowel obstruction, chronic pelvic pain, dyspareunia, infertility, and higher complication rates in subsequent operations. They are also a frequent source of medicolegal conflict. Thus, every physician should be familiar with their mechanism of origin, their consequences, and the methods by which they can be prevented. METHODS A selective PubMed/Medline search from 1960 onward as well as articles to which these publications referred. The expert consensus position of the European Society for Gynaecological Surgery is also taken into consideration. RESULTS Adhesions arise through aberrant wound healing after peritoneal injury with further influence from a variety of other factors. Preventive measures include minimizing peritoneal injury intraoperatively through the meticulous observance of basic surgical principles, moistening the mesothelium to keep it from drying out, irrigating the peritoneal cavity to remove blood and clot, and keeping the use of intra-abdominal foreign material to a minimum. CONCLUSION Adhesions are an inevitable consequence of intra-abdominal surgery. They can be prevented to some extent with meticulous surgical technique and certain other measures. For operations carrying a high risk of postoperative adhesions, e.g., surgery on the adnexa or bowel, commercially available peritoneal instillates or barrier methods can be used to limit adhesion formation.

Abstract
BACKGROUND Intra-abdominal adhesions are a major cause of morbidity and a significant drain on healthcare resources. Numerous anti-adhesion products have reached clinical use but none has been wholly satisfactory. This study examines the application of a modified chitosan-dextran (CD) gel to the intraperitoneal cavity to reduce adhesion formation. This is a unique synthetic gel, its active ingredients being succinyl chitosan and dextran aldehyde. MATERIALS AND METHODS Eighty adult male Wistar albino rats were randomized to undergo surgery alone or to receive CD gel at the time of surgery. Control groups using modified dextran only gel were also included. The surgical procedures comprised of laparotomy and either cecal abrasion or anastomotic simulation by enterotomy of the cecum with primary closure. At postoperative d 21 rats were euthanized by CO2 inhalation, and adhesions graded by an investigator blinded to the treatment groups, using a predetermined adhesion measurement score. RESULTS Adhesions were significantly reduced in the cecal abrasion group with median adhesion scores for the treatment group of 0 versus 3 in the control group (P<0.001, Fisher's exact test). Further reduction in adhesion formation was noted in the enterotomy group with median scores of 2 versus 5 for treatment and control groups respectively (P=0.003, Fisher's exact test). CONCLUSIONS Chitosan-dextran gel appears to significantly reduce the formation of intra-abdominal adhesions without adversely affecting wound healing. This is a noteworthy advancement in the safe prevention of post operative, intra-abdominal adhesions.

Abstract
OBJECTIVES A prior analysis of patients undergoing laparotomy for ovarian malignancies at our institution revealed an increased rate of intra-abdominal collections using HA-CMC film during debulking surgery. The primary objective of the current study was to determine whether the use of HA-CMC is associated with the development of postoperative intra-abdominal collections in patients undergoing laparotomy for uterine or cervical malignancies. METHODS We retrospectively identified all laparotomies performed for these malignancies from 3/1/05 to 12/31/07. We identified cases involving the use of HA-CMC via billing records and operative reports. Intra-abdominal collections were defined as localized intraperitoneal fluid accumulations in the absence of re-accumulating ascites. We noted incidences of intra-abdominal collections, as well as other complications. Appropriate statistical tests were applied using SPSS 15.0. RESULTS We identified 169 laparotomies in which HA-CMC was used and 347 in which HA-CMC was not used. The following were statistically similar in both cohorts: age, body mass index (BMI), primary site, surgery for recurrent disease, prior intraperitoneal surgery, and extent of current surgery. Intra-abdominal collections were seen in 6 (3.6%) of 169 HA-CMC cases compared to 10 (2.9%) of 347 non-HA-CMC cases (p=0.7). The rate of infected collections was similar in both groups (1.2% vs. 1.4%). In the subgroup that underwent tumor debulking, intra-abdominal collections were seen in 3 (11.5%) of 26 HA-CMC cases compared to 2 (5.4%) of 37 non-HA-CMC cases (p=0.6). CONCLUSIONS HA-CMC use does not appear to be associated with postoperative intra-abdominal collections in patients undergoing laparotomy for uterine or cervical cancer.

Abstract
STUDY OBJECTIVE To assess the laparoscopic handling and safety of D,L-polylactide-epsilon-caprolactone-trimethylene carbonate (PCT) copolymer after myomectomy and compare it with icodextrin. In contrast to previously developed solid barriers, the material has rationally designed properties that are advantageous for convenient laparoscopic application. DESIGN A randomized, single-blinded clinical study (Canadian Task Force Classification I). SETTING Single-center study in a German University Hospital. PATIENTS Thirty patients who underwent laparoscopic myomectomy were enrolled. INTERVENTIONS After laparoscopic myomectomy and subsequent reconstruction of the uterus with interrupted sutures, adhesion prophylaxis with either site-specific PCT copolymer or icodextrin occurred as per randomization. MEASUREMENTS AND MAIN RESULTS Except in 1 case, complete coverage of the uterine wound was achieved with PCT copolymer, and the mean time taken for application was 6.7 minutes. Mean application time for icodextrin was 1.1 minute. After introduction into the abdomen, PCT copolymer changed into a flexible state that adapted very well to the operative anatomy. The patients were followed up according to the study protocol for 3 months. There were no unforeseen adverse events, possible adhesion-related complications, or nonspecific complications in either study arm. There was no significant difference in pelvic pain scores between PCT copolymer and icodextrin groups 3 months after surgery. CONCLUSION In this pilot study, there were no adverse events, and the rationally designed material properties are favorable for laparoscopic application. No differences in postoperative pelvic pain were ascertained between PCT copolymer and icodextrin. Therefore a human phase II trial including second-look laparoscopy should be conducted to further evaluate this new solid adhesion barrier PCT copolymer.

Abstract
Background Postoperative adhesions occur when fibrous strands of internal scar tissue bind anatomical structures to one another. The most common cause of intra-abdominal adhesions is previous intra-abdominal surgical intervention. Up to 74% of intestinal obstructions are caused by post surgical adhesions. Although a variety of methods and agents have been investigated to prevent post surgical adhesions, the problem of peritoneal adhesions remains largely unsolved. Materials serving as an adhesion barrier are much needed. Methods/Design This is a prospective, randomised, controlled, patient blinded and observer blinded, single centre phase I-II trial, which evaluates the safety of A-Part® Gel as an adhesion prophylaxis after major abdominal wall surgery, in comparison to an untreated control group. 60 patients undergoing an elective median laparotomy without prior abdominal surgery are randomly allocated into two groups of a 1:1- ratio. Safety parameter and primary endpoint of the study is the occurrence of wound healing impairment or peritonitis within 28 (+10) days after surgery. The frequency of anastomotic leakage within 28 days after operation, occurrence of adverse and serious adverse events during hospital stay up to 3 months and the rate of adhesions along the scar within 3 months are defined as secondary endpoints. After hospital discharge the investigator will examine the enrolled patients at 28 (+10) days and 3 months (±14 days) after surgery. Discussion This trial aims to assess, whether the intra-peritoneal application of A-Part® Gel is safe and efficacious in the prevention of post-surgical adhesions after median laparotomy, in comparison to untreated controls.

Abstract
Post-operative adhesions are a significant complication of all abdominal surgical procedures. The major strategies for adhesion prevention in gynaecological surgery are focused on the optimization of surgical technique and use of anti-adhesive agents, which fall into two main categories: pharmacological agents and barriers. Surgical technique that minimizes peritoneal trauma can reduce, but cannot prevent post-operative adhesion formation. Various local and systemic drugs that can alter the local inflammatory response, inhibit the coagulation cascade and promote fibrinolysis have been evaluated. Limited data support the administration of post-operative corticosteroids in addition to systemic intra-operative corticosteroids for the prevention of adhesions after gynaecological surgery. None of the remaining pharmacological agents have been found effective for the reduction of post-operative adhesions. Barriers are currently considered the most useful adjuncts, which may reduce adhesion formation. They act by separating the traumatized peritoneal surfaces during the healing period. The separation can be achieved by solid barriers or fluids. There is limited evidence from randomized clinical trials that support the beneficial effect of most of these barrier agents in the prevention of intra-peritoneal adhesions after gynaecological surgery. However, the evidence is not adequate for definite conclusions to be drawn and further research in this field is warranted.

Abstract
OBJECTIVES To determine whether HA-CMC was associated with the development of postoperative intra-abdominal collections in patients undergoing laparotomy for ovarian, fallopian tube, or primary peritoneal malignancies. METHODS We retrospectively identified all laparotomies performed for these malignancies from March 1, 2005 to December 31, 2007. The use of HA-CMC was identified. Laparotomies for malignant bowel obstruction or repair of fistulae were excluded. Intra-abdominal collections, non-infected and infected, were defined as localized intraperitoneal fluid accumulations in the absence of re-accumulating ascites. All other complications were also captured. Appropriate statistical tests were applied using SPSS 15.0. RESULTS We identified 219 laparotomies with HA-CMC and 204 without HA-CMC. Upper abdominal resections were performed in 65/219 (30%) HA-CMC cases compared to 39/204 (19%) cases without HA-CMC (P=0.01). The rates of large bowel and/or rectal resections were similar in both cohorts. Intra-abdominal collections were seen in 18/219 (8.2%) HA-CMC cases compared to 5/204 (2.5%) cases without HA-CMC (P=0.009). HA-CMC was independently associated with the diagnosis of a postoperative intra-abdominal collection (P=0.01). All but 2 collections developed in patients undergoing debulking procedures. CONCLUSIONS HA-CMC appears to be associated with a higher rate of postoperative intra-abdominal collections. This seems to be greatest in patients who are undergoing a debulking procedure.

Abstract
STUDY OBJECTIVE To provide a comprehensive review of the best evidence available in the laparoscopic management of endometriosis for pain and/or fertility and to provide practical recommendations based on this information. DESIGN Review article of randomized controlled trials. PATIENTS Women with endometriosis. METHODS A systematic search was performed of the Cochrane Library and MEDLINE database for randomized controlled trials relating only to laparoscopic management of endometriosis. The information from 7 Cochrane review articles and 35 original randomized trials is presented in a clinically relevant question-and-answer format. CONCLUSIONS Awareness of endometriosis as a disease with substantial morbidity is vitally important. Laparoscopic treatment of endometriosis is beneficial for reducing pain and improving fertility. Laparoscopic presacral neurectomy, but not laparoscopic uterosacral nerve ablation, is a useful adjunct to conservative surgery for endometriosis in patients with a midline component of pain. Preoperative hormonal suppression with gonadotropin-receptor hormone analogue may be helpful in decreasing endometriosis disease scores. Postoperative hormonal suppression with either a gonadotropin-receptor hormone analogue or progestin (including the levonorgestrel intrauterine system) may be helpful in reducing pain and increasing time to recurrence of symptoms. Excisional cystectomy is the preferred method to treat endometrial cysts for both pain and fertility and may be aided by the use of mesna and initial circular excision. An absorbable adhesion barrier (Interceed), 4% icodextrin solution (Adept), and a viscoelastic gel (Oxiplex/AP, FzioMed, Inc., San Luis Obispd, CA; not available in the United States) are safe and effective products to help prevent adhesions in laparoscopic surgery to treat endometriosis.

[PMID: 19482275 DOI: 10.1016/j.fertnstert.2009.03.023] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2008] [Revised: 02/26/2009] [Accepted: 03/09/2009] [Indexed: 11/18/2022]
Abstract
OBJECTIVE To describe complications due to adhesion formation following cesarean sections and methods to prevent adhesion formation. DESIGN Case reports. SETTING Labor and delivery suites in three hospitals. PATIENT(S) [1] A 32-year-old G2P1 undergoing a repeat cesarean section with severe adhesions and subsequent bladder injury and repair. [2] A 36-year-old G3P1 undergoing a vaginal birth after cesarean (VBAC) with partial uterine dehiscence, fetal distress, and dense pelvic adhesions. [3] A 38-year-old G4P2 undergoing repeat cesarean section with dense adhesions from the uterus to the anterior abdominal wall. INTERVENTION(S) Cesarean sections, lysis of adhesions, and cystotomy repair. RESULT(S) All three patients had significant complications and sequelae secondary to dense uterine adhesions from previous cesarean sections. CONCLUSION(S) Adhesion prevention measures should be routinely implemented to reduce adhesion formation after cesarean deliveries and thus decrease corresponding sequelae. Critical steps to decrease adhesion formation include practicing meticulous surgical techniques, gentle tissue handling, minimizing ischemia and desiccation, controlling hemostasis, avoiding powdered gloves, and achieving peritoneal closure. Based on available data, adhesion barriers are effective in preventing or reducing adhesions after gynecologic surgery and have also been effective following cesarean sections.

Abstract
Postoperative adhesions are a natural consequence of surgical tissue trauma and healing and may result in infertility, pain, and bowel obstruction. Adherence to microsurgical principles, minimally invasive surgery, and use of some peritoneal instillates may help to decrease postoperative adhesions. Some surgical barriers have been demonstrated effective for reducing postoperative adhesions, but there is no substantial evidence that their use improves fertility, decreases pain, or reduces the incidence of postoperative bowel obstruction.

A sprayable hydrogel adhesion barrier facilitates closure of defunctioning loop ileostomy: a randomized trial. Dis Colon Rectum 2008; 51:956-60. [PMID: 18219530 DOI: 10.1007/s10350-007-9181-4] [Citation(s) in RCA: 47] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2007] [Revised: 09/06/2007] [Accepted: 10/17/2007] [Indexed: 02/08/2023]
Abstract
PURPOSE Closure of defunctioning loop ileostomy often is associated with division of complex peristomal adhesions through a parastomal incision with limited exposure. The goal was to determine whether sprayable hydrogel adhesion barrier (SprayGel) will reduce peristomal adhesions and facilitate closure of ileostomy. METHODS Patients undergoing closure of loop ileostomy were randomized to have hydrogel adhesion barrier sprayed around both limbs of ileostomy for 20 cm (SprayGel group, n = 19), or to control without adhesion barrier (control group, n = 21). Ileostomy was reversed at ten weeks after construction. Extent of peristomal adhesions was scored in blinded manner (each quadrant, range, 1-3: 3 = most severe; total, range, 4-12: 12 = most severe). RESULTS Use of adhesion barrier was associated with significant reduction in overall adhesion scores (mean, 6.11 vs. 9.67; P < 0.0005), four-quadrant adhesion scores (Quadrant A: 1.68 vs. 2.52, P = 0.002; Quadrant B: 1.42 vs. 2.33, P < 0.0005; Quadrant C: 1.42 vs. 2.24, P < 0.0005; Quadrant D: 1.58 vs. 2.48, P = 0.002), and proportion of patients with dense (scores > or = 8) adhesions (0.11 vs. 0.71; P < 0.0005). Time taken to mobilize (16.53 vs. 21.67 minutes; P = 0.008) and close ileostomy (35.37 vs. 41.90 minutes; P = 0.008) was significantly reduced. Postoperative complications were comparable. CONCLUSIONS A sprayable hydrogel adhesion barrier placed around the limbs of a defunctioning loop ileostomy reduced peristomal adhesions and might facilitate closure of ileostomy.

Abstract
BACKGROUND Pelvic adhesion can form as a result of inflammation, endometriosis or surgical trauma. During pelvic surgery, strategies to reduce pelvic adhesion formation may include placing synthetic barrier agents such as oxidised regenerated cellulose, polytetrafluoroethylene or Fibrin sheets between the pelvic structures. OBJECTIVES To assess the effect of physical barriers used during pelvic surgery in women of reproductive age on pregnancy rates, pelvic pain, or postoperative adhesion reformation. SEARCH STRATEGY We searched the Cochrane Menstrual Disorders and Subfertility Group Trials Register (searched September 2007) which is based on regular searches of MEDLINE, EMBASE, CINAHL, PsycINFO and CENTRAL, plus handsearching of 20 relevant journals and conference proceedings, and searches of several key grey literature sources. In addition, companies were contacted for unpublished trials. SELECTION CRITERIA Any randomised controlled trials (RCTs) comparing the use of physical barriers versus no treatment or other physical barriers in the prevention of adhesions in women undergoing gynaecological surgery. DATA COLLECTION AND ANALYSIS Review authors assessed trial eligibility and quality. MAIN RESULTS Sixteen RCTs were included. Five trials randomised patients while the remainder randomised pelvic organs. Laparoscopy (six trials) and laparotomy (10 trials) were the primary surgical techniques. Indications for surgery included myomectomy (five trials), ovarian surgery (five trials), pelvic adhesions (four trials), endometriosis (one trial), and mixed (one trial). Eleven trials assessed Interceed versus no treatment, two assessed Interceed versus Gore-Tex, one trial assessed Gore-Tex versus no treatment, and one trial assessed Seprafilm versus no treatment. A single trial assessed Fibrin sheet versus no treatment. No studies reported pregnancy or reduction in pain as outcomes. The use of Interceed was associated with reduced incidence of pelvic adhesion formation, both new formation and reformation following laparoscopic surgery or laparotomy. However, this result should be interpreted with caution. Gore-Tex was more effective than no barrier or Interceed in preventing adhesion formation. There was only limited evidence that Seprafilm was effective in preventing adhesion formation following myomectomy and no evidence to support Fibrin sheet. AUTHORS' CONCLUSIONS The absorbable adhesion barrier Interceed reduces the incidence of adhesion formation following laparoscopy and laparotomy, but there are insufficient data to support its use to improve pregnancy rates. Gore-Tex may be superior to Interceed in preventing adhesion formation but its usefulness is limited by the need for suturing and later removal. There was no evidence of effectiveness of Seprafilm and Fibrin sheet in preventing adhesion formation.
