Ovulation provides excessive coagulation and hepatocyte growth factor signals to cause postoperative intraabdominal adhesions. iScience 2024; 27:109788. [PMID: 38770140 PMCID: PMC11103365 DOI: 10.1016/j.isci.2024.109788] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 03/14/2024] [Accepted: 04/16/2024] [Indexed: 05/22/2024] Open
Abstract
Postoperative adhesions show a higher occurrence in females aged 16-60, especially after pelvic surgeries. This study explores the role of ovulation in adhesion formation in mice. Ovarian surgery in mice with normal- or super-ovulation led to pronounced adhesions, whereas ovulation-defective Pgr-KO mice showed minimal adhesions. Specifically, exposure to ovulatory follicular fluid (FF) markedly increased the adhesion. The hazardous exposure time window was one day before to 2.5 days after the surgery. Mechanistically, early FF exposure triggered adhesions via the blood coagulation cascade, while later exposure relied on the HGF/cMET signaling pathway. Prophylactic administration of a thrombin inhibitor pre-operatively or a cMET inhibitor postoperatively effectively mitigated FF-induced adhesions, while COX inhibitor treatment exhibited no discernible effect. These findings underscore ovulation as a pivotal factor in the development of pelvic wound adhesions and advocate for targeted preventive strategies such as c-MET inhibition, scheduling surgeries outside the ovulatory period, or employing oral contraceptive measures.

Abstract
The formation of pneumoperitoneum involves the process of inflating the peritoneal cavity during laparoscopic and typically uses CO2 as the insufflation gas. This review aims to identify ideal gas mixtures for establishing the pneumoperitoneum with animal and human studies undertaken up to the writing of this review. A systematic search of PubMed, OVID, and clinicaltrials.gov was performed to identify studies on the utilisation of mixed gases in laparoscopic surgery, including non-randomised/randomised trials, animal and human studies, and studies with inflating pressures between 12 and 16 mmHg. ROBINS-I and RoB2 tool was used to assess the risk of bias. A narrative synthesis of results was performed due to the heterogeneity of the studies. 5 studies from the database search and 5 studies from citation search comprising 128 animal subjects and 61 human patients were found. These studies collated results based on adhesion formation (6 studies), pain scores (2 studies) and other outcomes, with results favouring the use of carbon dioxide + 10% nitrous oxide + 4% oxygen. This has shown a significant reduction in adhesion formation, pain scores and inflammation. The use of this gas mixture provides promising results for future practice. Several of the studies available require larger sample sizes to develop a more definitive answer on the effects of different gas mixtures. Furthermore, the number of confounding factors in randomised trials should be reduced so that each component of the current suggested gas mixture can be tested for safety and efficacy.

Adv Radiat Oncol 2024; 9:101303. [PMID: 38260232 PMCID: PMC10801660 DOI: 10.1016/j.adro.2023.101303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Accepted: 06/16/2023] [Indexed: 01/24/2024] Open
Abstract
Purpose To determine the effects of intra-abdominal surgery on the intensities of 5 radiation-induced intestinal syndromes in survivors of pelvic cancer. Methods and Materials The analysis included 623 women born in 1927 or later who had survived cancer. They all had received external radiation therapy toward the pelvic area to treat gynecologic cancers. Information from 344 women who did not undergo irradiation, matched for age and residency, was also included. Main outcome measures after the surgical procedures were the intensity scores for 5 radiation-induced intestinal syndromes: urgency-tenesmus syndrome, fecal-leakage syndrome, excessive mucus discharge, excessive gas discharge, and blood discharge. The scores were based on symptom frequencies obtained from patient-reported outcomes and on factor loadings obtained from a previously reported factor analysis. Follow-up was 2 to 15 years after radiation therapy. Results Among survivors of cancer, intra-abdominal surgery increased the intensity of the urgency-tenesmus syndrome, the fecal-leakage syndrome, excessive gas discharge, and blood discharge but had a negligible effect on mucus discharge. Intra-abdominal surgery had an especially negative effect on the urgency-tenesmus syndrome. Although the combination of appendectomy with 1 or more other intra-abdominal surgeries resulted in the highest score for all syndromes, appendectomy alone had weak to no effect. In women who did not undergo irradiation, a similar pattern was seen, albeit with much lower scores. Conclusions We found intra-abdominal surgery to be a risk factor among survivors of gynecologic cancer, increasing the intensity score of 4 out of 5 radiation-induced intestinal syndromes. During radiation therapy, it may be worthwhile to pay extra attention to the dose of unwanted ionizing radiation to the intestines if the patient previously has undergone intra-abdominal surgery.

Abstract
This study was conducted to explore the influencing factors of gastrointestinal function recovery after cesarean section (CS), which could provide a reference for the enhanced recovery after surgery in obstetrics. This is a cross-sectional survey on Chinese mothers receiving CS. The participants's socio-demographic characteristics, perioperative diet, medical condition and gastrointestinal function after surgery were collected by a self-designed questionnaire. Binary logistic regression analysis was employed to explore the influencing factors of gastrointestinal function recovery after CS. A total of 1501 (94.76%) valid questionnaires were collected. The first borborygmus was 2.21 ± 0.63 hours, and the first anal exhaust was 35.73 ± 14.85 hours after the CS. The incidence of abdominal distension and intestinal obstruction were 15.1% and 0.7%, respectively. The parity, type of CS, 2-hours bleeding after surgery, time of first meal after surgery, whether taking peppermint water after surgery were the independent influencing factors for gastrointestinal function recovery after CS. We should pay more attention to the mothers with scarred uterus, manage the labor process strictly, and reduce 2-hours bleeding after surgery. The mothers with CS should also be encouraged to eat early and take peppermint water to promote intestinal peristalsis actively.

Abstract
BACKGROUND Postoperative adhesions may occur after >90% of laparotomies and is the most common cause of small bowel obstruction (SBO). Despite the high incidence, there is a lack of data related to financial implications of adhesion-related SBO (ASBO). This systematic literature review of in-hospital costs for treatment of ASBO searched PubMed, Scopus and Google Scholar databases according to PRISMA guidelines. Exclusion criteria were reviews, editorials, clinical vignettes, studies of patients <18 years of age, studies with no English full text and studies assessing adhesiolysis for causes other than SBO or that used extrapolations with economic models. Main outcome measures were financial costs per patient and national costs. RESULTS Seven studies, published between 1999 and 2016, incorporating a total of 39 573 patients, were identified. Four were undertaken in European countries, one in the USA, 1 in New Zealand and 1 in Nigeria. Overall national costs regarding treatment of patients with ASBO ranged between $3.468 million and $1.77 billion. Median overall cost in the medical management group was $2371.5 ($1814-$2568) vs $12370 ($4914-$25321) in the surgical group. Median length of stay was 4 (3-7) days for patients conservatively treated and 11.5 (8-16.3) days for patients who underwent surgery. Median length of stay of operated patients on was almost triple that of patients conservatively managed. CONCLUSIONS Given the major financial implications of ASBO, further initiatives are needed to avoid operations for SBO when clinically appropriate and minimize delays taking patients with high suspicion of complete SBO to the operating room.

Abstract
Postoperative intraabdominal adhesions can occur after more than 90% of gynecologic surgeries. They not only cause chronic pelvic pain and small bowel obstruction, but are also one of the main reasons for infertility. Adhesions are not only a burden for the affected patients, but are also a burden for the healthcare system, since the treatment of adhesion-associated complications costs a considerable amount of money. The gold standard for the diagnosis of adhesions is by laparoscopy, although other methods, such as transvaginal hydro-laparoscopy, are being discussed as better alternatives. Ideally, adhesions are avoided inherently, by operating carefully and by using microsurgical principles. If this is not possible, gel barriers have been shown to be successful in reducing postoperative adhesions.

Abstract
STUDY OBJECTIVE To test the hypothesis that intraperitoneal instillation of a single bolus dose of l-alanyl-l-glutamine (AG) will reduce the incidence, extent and/or severity of adhesions following myomectomy and establish preliminary safety and tolerability of AG in humans. DESIGN Phase 1,2 Randomized, double-blind, placebo-controlled study (DBRCT). SETTING Tertiary care gynecology surgical centre. PATIENTS Thirty-eight women who underwent myomectomies by laparoscopy (N = 38; AG-19 vs Placebo-19) or laparotomy (N = 10; AG-5 vs Placebo-5) with a scheduled second-look laparoscopy (SLL) 6-8 weeks later. Thirty-two patients in the laparoscopy arm completed SLL. INTERVENTIONS Bolus dose of AG or normal saline solution control (0.9% NaCl) administered intraperitoneally immediately prior to suture closure of the laparoscopic ports. The average dose was 170 mL of AG or control based on a dosing scheme of 1 g/kg bodyweight. MEASUREMENTS Digital recordings obtained for all procedures. The primary endpoint was reduction in the incidence, severity and extent of post-operative adhesions analyzed by intention-to-treat (ITT) approach. Three independent, blinded reviewers evaluated all operative video recordings to assess presence of adhesions. Post-hoc analysis assessed presence or absence of adhesions in the peritoneal cavity. Secondary endpoints assessed safety and tolerability of AG. MAIN RESULTS Administration of AG reduced the incidence, severity and/or extent of post-operative adhesions (p = 0.046). The presence of adhesions in the AG group was lower than in the Control group (p = 0.041). Adhesion improvement was achieved in 15 of 15 (100%) in the AG group versus 5 of 17 (29.6%) in the placebo group. No serious adverse events were reported. No differences in safety parameters were observed. CONCLUSIONS Intraperitoneal l-alanyl-l-glutamine reduced adhesion formation in all patients following laparoscopic myomectomy. Complete absence of adhesions was achieved at all abdominal sites in 93% of patients. Results confirm AG's known effects on cellular mechanisms of adhesiogenesis and lay the foundation for new adhesion prophylaxis research and treatment.

Risk Factors for Adhesion-Related Readmission and Abdominal Reoperation after Gynecological Surgery: A Nationwide Cohort Study. J Clin Med 2023; 12:jcm12041351.

Abstract
More than half of women in developed countries undergo surgery during their lifetime, putting them at risk of adhesion-related complications. Adhesion-related complications include small bowel obstruction, chronic (pelvic) pain, subfertility, and complications associated with adhesiolysis during reoperation. The aim of this study is to predict the risk for adhesion-related readmission and reoperation after gynecological surgery. A Scottish nationwide retrospective cohort study was conducted including all women undergoing a gynecological procedure as their initial abdominal or pelvic operation between 1 June 2009 and 30 June 2011, with a five-year follow-up. Prediction models for two- and five-year risk of adhesion-related readmission and reoperation were constructed and visualized using nomograms. To evaluate the reliability of the created prediction model, internal cross-validation was performed using bootstrap methods. During the study period, 18,452 women were operated on, and 2719 (14.7%) of them were readmitted for reasons possibly related to adhesions. A total of 2679 (14.5%) women underwent reoperation. Risk factors for adhesion-related readmission were younger age, malignancy as indication, intra-abdominal infection, previous radiotherapy, application of a mesh, and concomitant inflammatory bowel disease. Transvaginal surgery was associated with a lower risk of adhesion-related complications as compared to laparoscopic or open surgeries. The prediction model for both readmissions and reoperations had moderate predictive reliability (c-statistics 0.711 and 0.651). This study identified risk factors for adhesion-related morbidity. The constructed prediction models can guide the targeted use of adhesion prevention methods and preoperative patient information in decision-making.

Abstract
BACKGROUND Adhesive intestinal obstruction (AIO) is a common surgical emergency. Surgical exploration has a considerable risk of intestinal injury, and surgical treatment may greatly reduce the quality of life after surgery and cause AIO after re-operation. The nonsurgical treatment is effective for approximately 70% to 90% of patients with adhesive small bowel obstruction (ASBO). However, the high recurrence (30%) and mortality (2%) rates of ASBO are concerning. Moreover, the ideal management method of ASBO remains debatable. Studies have shown that acupuncture can also promote postoperative gastrointestinal function recovery and prevent postoperative complications such as nausea, vomiting, and visceral pain. AIM We aimed to evaluate the effectiveness of acupuncture in the treatment of AIO. METHODS Randomized controlled trials investigating the effectiveness of acupuncture for adhesive bowel obstruction published until November 2021 were identified by searching 8 comprehensive databases. Data analysis was performed using RevMan v. 5.4 and Stata software v. 16.0. The random-effects model and the fixed-effects model were used to perform the meta-analysis on the experimental group and control group. RESULTS Twelve studies with a total of 892 participants were included. The results showed that the experimental group had a significantly higher effective rate (relative risk: 1.20; 95% confidence interval (CI): 1.11-1.28; P < .00001) and a markedly shorter time of the first defecation (mean difference: -11.49, 95% CI: -19.31 to -3.66; P = .004) than the control group. The experimental group also showed a reduction in the duration of abdominal pain, and the reduced length of hospital stay. However, no statistical differences were observed between the 2 groups in terms of the surgery conversion rate. CONCLUSION Acupuncture is effective in the treatment of AIO. It can remarkably alleviate some clinical symptoms in patients with AIO.

Abstract
Objectives People with ileus is one of the patient groups with the highest admission rates to the emergency departments. In this study, it was aimed to determine the effects of age groups and etiological factors on mortality when evaluated together with gender. Material and Methods In our study, patients who were consulted from the Emergency Service to the General Surgery department with a pre-diagno- sis of abdominal pain between 2009 and 2020 were retrospectively screened. Patients hospitalized for ileus were analyzed in terms of age (18-65 years and over 65 years), gender, operation, etiology, incidence, and mortality. Results Between 2009 and 2020, 534 (3.03%) of 17.601 patients who received emergency consultation from the general surgery clinic were diagnosed with ileus. While 253 (47.4%) of the patients were operated, 317 (59.4%) patients and 101 (18.9%) patients were diagnosed with brid and malignancy, respectively; and 21 (3.9%) patients died in the complete patient group (Table 1). While the incidence of brid was high in non-operated patients, in operated patients, malignancy and other pathologies was found to be higher (p <0.001) (Table 2). While, in patients 65 years and older, mortality was observed in 10.6% of women and 2.6% of men, it was determined that the mortality rate was higher in women (p= 0.008) (Figure 4). Conclusion The mortality rate in patients hospitalized with the diagnosis of mechanical bowel obstruction was found to be statistically significantly higher in female patients aged 65 and over.

Abstract
Small bowel obstructions (SBO) are a common surgical problem accounting for up half of all emergency laparotomies in the United States. SBO in the virgin abdomen (SBO-VA) presents surgeons with a unique predicament as historical teaching has mandated operative exploration in these situations due to their association with more sinister etiologies. More recent research has demonstrated that this may not be the case, with adhesive disease comprising the majority of SBO-VA. Small bowel neoplasms however comprise a considerable portion of SBO-VA. Small bowel tumors comprise around 0.5%-2% of all gastrointestinal tumors, with adenomas being the most common type of benign small bowel tumor. These lesions are most commonly encountered in the duodenum, typically involving the peri-ampullary region, Their incidence decreases with descent down the gastrointestinal tract, and are least commonly found in the ileum. Ileal adenomas have been increasingly described in the literature with the rise of advanced imaging and endoscopic capabilities. The vast majority of these lesions remain asymptomatic; however, they have been reported to undergo malignant transformation resulting in obstruction and intussusception. Small bowel obstruction due to ileal adenomas in the absence of malignancy is exceedingly rare, with only one previously reported case in the literature. We describe a case of an SBO-VA secondary to ileal stricture caused by a tubulo-villous adenoma. We then discuss the topics of SBO and SBO-VA, specifically regarding their etiology and historical and modern management, with a particular focus on the diagnosis and management of small bowel neoplasms, specifically small bowel adenomas.

Abstract
BACKGROUND Adhesive small bowel obstruction (ASBO) is one of the major causes of postoperative morbidity. Non-surgical management is generally applied to non-strangulated ASBO. Several factors have been reported to affect the response to non-surgical management in patients with ASBO. However, the association between sex differences and non-strangulated ASBO remains unclear. This study aimed to elucidate the effect of sex differences in non-strangulated postoperative ASBO. METHODS We divided 139 patients with a first episode of non-strangulated postoperative ASBO into two groups: male group (n = 83) and female group (n = 56). Clinical features and prognosis were compared between the two groups. RESULTS Female patients had lower proportions of oesophageal/gastric malignancies (P = 0.044) and colorectal malignancies (P = 0.030) and a higher proportion of uterine/ovarian malignancies (P < 0.001) than male patients did. More female patients required surgical management than male patients (P = 0.003) did. Hospital length of stay (LOS) was longer (P = 0.046) in the female group than in the male group. Multiple logistic regression analysis showed that the female sex was associated with an increased risk of the need for surgical management (odds ratio 5.318, P = 0.006). Cox proportional hazards regression analysis revealed that the female sex was positively associated with increased LOS (hazard ratio 0.687, P = 0.045). CONCLUSION Female sex was associated with failure of non-surgical management and increased LOS in patients with non-strangulated postoperative ASBO.

Abstract
Background Small bowel obstruction (SBO) is a common surgical emergency, causing high morbidity and healthcare costs. The majority of SBOs are caused by adhesions that result from previous surgeries. Bowel obstruction, however, also occurs in patients without previous operation or known pathology, a so called virgin abdomen. It is unknown if small bowel obstruction in the virgin abdomen (SBO-VA) can be managed according to the same principles as other cases of small bowel obstruction. The aim of this position paper is to evaluate the available evidence on etiology and management of small bowel obstruction in the virgin abdomen. Methods This is a narrative review with scoping aspects. Clinical topics covered in this review include epidemiology and etiology of SBO-VA, diagnosis and imaging, initial assessment, the role of surgical management in SBO-VA, and the role of non-operative management in SBO-VA. Results Our scoping search revealed seven original studies reporting original patient data related to SBO-VA. All the included studies are retrospective cohorts, with populations ranging between 44 and 103 patients with SBO-VA. Adhesions were found to be the cause of the obstruction in approximately half of the reported cases of SBO-VA. A relatively high number of cases of SBO-VA were managed surgically with studies reporting 39–83%. However, in cases where a trial of non-operative management was started, this was generally successful. Conclusion The data available suggest that etiology and treatment results for patients with SBO-VA are largely comparable to the results in patients with SBO after previous abdominal surgery. We therefore propose that patients with a virgin abdomen could be treated according to existing guidelines for SBO and adhesive small bowel obstruction.

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
Summary
Background
The most frequent abdominal surgery performed for benign disease in females of fertile age is appendectomy, which remains among the most common surgeries and is a possible cause of peritoneal adhesions. The fact that appendectomy can cause adhesions may lead one to think that this may be a relevant risk factor for infertility; however, there is no universal agreement regarding the association between appendectomy and fertility. The aim of this review is to evaluate weather appendectomy may have a relevant impact on female fertility.
Methods
The search was conducted in PubMed and there was no limitation set on the date of publication. All studies regarding populations of female patients who had undergone appendectomy for inflamed appendix, perforated appendix, or negative appendix between childhood and the end of the reproductive period were included.
Results
Some authors believe that pelvic surgery can cause adhesions which can potentially lead to tubal infertility by causing tubal obstruction or by altering motility of fimbriae, tubal fluid secretion, and embryo transport. On the other hand, the most recent evidence reported that removal of the appendix seems to be associated with an increased pregnancy rate in large population studies.
Conclusion
Despite the existence of contrasting opinions concerning fertility after appendectomy, the most recent evidence suggests that appendectomy may actually lead to improved fertility and decreased time to pregnancy. Appendectomy seems to be correlated with improved fertility and higher pregnancy rates.

Abstract
OBJECTIVE We sought to determine if past surgical history is associated with perioperative outcomes for patients undergoing hysterectomy. METHODS A retrospective cohort study was conducted at a single, tertiary, academic health system of women who underwent hysterectomy from May 2016 - May 2017. Past surgical history (PSH) involving any abdominal or pelvic surgery, baseline demographics and perioperative outcomes were collected. For purposes of analyses, PSH was defined using three algorithms: 1) any prior abdominopelvic surgery, 2) having had abdominopelvic surgeries likely to cause adhesive disease, 3) anatomic location of prior PSH (none; pelvic; abdominal; or abdominal+pelvic). Descriptive, bivariable and multivariable analyses were performed. RESULTS 1256 patients underwent hysterectomy. In adjusted analyses, PSH defined by any prior abdominopelvic surgery was associated with length of stay (LOS) (2.1 days (95%CI 1.9, 2.2) vs. 1.8 (95%CI 1.6, 2.0), (p=0.02)). PSH of procedures likely to cause adhesive disease was associated with greater estimated blood loss (EBL) (243.2 mL (95%CI 208.1, 278.3) vs. 189.0 (95%CI 1734, 204.7), (p=0.01)), longer LOS (2.5 days (95%CI 2.2, 2.8) vs. 1.9 (95%CI 1.7, 2.0), (p<0.01)), and more readmissions (OR 2.4, 95%CI 1.3, 4.5) (p<0.01). PSH defined by anatomic location revealed a trend (p=0.07) towards greater EBL in those with prior pelvic or abdominal+pelvic surgery compared to none or abdominal only, whereas LOS, readmissions and operative times did not differ. Increased total number of prior open surgeries was associated with operative time (p<0.0001), EBL (p<0.0001), hospital LOS (p<0.0001) and readmission (p=0.026). CONCLUSIONS Prior abdominopelvic surgery is associated with worse perioperative outcome measures in women undergoing hysterectomy.

Abstract
Uterine fibroids or uterine myomas are one of the most common benign diseases of the uterus. Symptoms associated with myomas can make surgical removal of myomas necessary. Besides the traditional abdominal route, laparoscopic myomectomy (LM) has gained more acceptances over the last few decades, and it is anticipated that laparoscopy is associated with lower adhesion development. Therefore, we conducted this review to analyze the evidence on adhesions after LM. The PubMed database was searched using the search terms “myomectomy” alone and in combination with “adhesions,” “infertility OR fertility outcome,” and “laparoscopy” among articles published in English and German. Although the well-known advantages of laparoscopy, for example, less pain, less blood loss, or shorter hospital stay, myomectomy belongs to high-risk operations concerning adhesion formation, with at least every fifth patient developing postsurgical adhesions. In laparoscopic surgery, surgeons´ experience as well tissue trauma, due to desiccation and hypoxia, are the underlying mechanisms leading to adhesion formation. Incisions of the posterior uterus may be associated with a higher rate of adhesions compared to anterior or fundal incisions. Adhesions can be associated with severe complications such as small bowel obstruction, chronic pelvic pain, complications in further operations, or impaired fertility. Tissue trauma and the experience of the surgeon in laparoscopic surgery are most of the influencing factors for adhesion formation after myomectomy. Therefore, every surgeon should adopt strategies to reduce adhesion development in daily routine, especially when it conducted to preserve or restore fertility.

Abstract
Background The worldwide incidence of birth by Caesarean Section (CS) is rising. Many births after a previous CS are by repeat surgery, either by an elective CS or after a failed trial of labour. Adhesion formation is associated with increased maternal morbidity in patients with repeat CSs. In spite of large-scale studies the relation between the incidence of adhesion formation and CS surgical technique is unclear. This study aims to assess maternal and neonatal morbidity and mortality after repeat CSs in a rural hospital in a low-income country (LIC) and to analyse the effect of surgical technique on the formation of adhesions. Methods A cross-sectional, retrospective medical records study of all women undergoing CS in Ndala Hospital in 2011 and 2012. Results Of the 3966 births, 450 were by CS (11.3%), of which 321 were 1st CS, 80 2nd CS, 36 3rd CS, 12 4th and one 5th CS (71, 18, 8, 3 and 0.2% respectively). Adhesions were considered to be severe in 56% of second CSs and 64% of third CSs. In 2nd CSs, adhesions were not associated with closure of the peritoneum at 1st CS, but were associated with the prior use of a midline skin incision. There was no increase in maternal morbidity when severe adhesions were present. Adverse neonatal outcome was more prevalent when severe adhesions were present, but this was statistically non-significant (16% vs 6%). Conclusions Our results give insight into the practice of repeat CS in our rural hospital. Adhesions after CSs are common and occur more frequently after midline skin incision at 1st CS compared to a transverse incision. Reviewing local data is important to evaluate quality of care and to compare local outcomes to the literature.

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
OBJECTIVE To investigate whether the presence of peritoneal adhesions at the second cesarean delivery (CD) are associated with peri-partum hemorrhagic complications. STUDY DESIGN A retrospective cohort study was undertaken, comparing hemorrhagic complications in the second CD, between women with and without adhesions. All women with two CDs who delivered a singleton in their second CD between the years 1988-2016 at a large regional medical center in Israel were included. Women with adhesions diagnosed at the first CD and women with a history of other abdominal or pelvic surgery, pelvic infection or inflammatory disease, endometriosis, uterine Mullerian anomalies and fetal chromosomal or structural abnormalities were excluded from the analysis, resulting in a sample of 7925 women. Peri-partum hemorrhagic complications were defined as a composite of vessel ligation, B lynch procedure during the CD or uterine rupture, third stage or immediate postpartum hemorrhage, blood component transfusion, hemorrhagic shock and maternal anemia [hemoglobin (Hb) levels prior to maternal discharge below 9.0 g\dl]. In order to identify variables that are independently associated with the composite peri-partum hemorrhagic complications a multivariate logistic regression analysis was performed, to control for potential confounders. In addition, a linear regression model was constructed with Hb levels as the outcome variable. RESULTS During the study period, 32.6 % of patients (n = 2581) suffered from adhesions during the second CD. After adjusting for potential confounders, peri-partum hemorrhagic complications were found to be significantly associated with the presence of peritoneal adhesions (adjusted OR 1.18, CI 1.04-1.33, P = 0.008). A multivariate linear regression analysis revealed that peritoneal adhesions were independently associated with a decline in post-partum Hb levels (β=-0.055, P < 0.001). CONCLUSION Adhesions attributable to a previous CD increase the risk for hemorrhagic complications. Interventions aimed at preventing adhesions formation during the primary CD may have a role in reducing hemorrhagic complications in subsequent CDs.

Incidence and risk factors of early postoperative small bowel obstruction in patients undergoing hysterectomy for benign indications. Am J Obstet Gynecol 2019; 220:251.e1-251.e9. [PMID: 30471258 DOI: 10.1016/j.ajog.2018.11.1095] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Revised: 10/30/2018] [Accepted: 11/15/2018] [Indexed: 11/30/2022]
Abstract
BACKGROUND Small bowel obstruction (SBO) is a major cause of postoperative mortality and morbidity following abdominal and pelvic surgery, with 225,000-345,000 annual admissions. SBO may be classified based on onset from day of surgery. Early SBO occurs within the first 30 days following surgery, whereas late SBO occurs after the initial 30-day postoperative window. The majority of either type of bowel obstruction is believed to be secondary to intra-abdominal adhesions. Early SBO warrants special attention because of the difficulty in distinguishing between mechanical and nonmechanical obstruction during this period. Whereas conservative management often leads to resolution of nonmechanical obstruction and some partial SBO, surgical management is associated with a higher rate of complications compared to surgery for late SBO because of the presence of hypervascular adhesions in the early postoperative period. The current literature regarding SBO, and early SBO in particular, following hysterectomy is limited. Given that approximately 400,000 hysterectomies are performed annually, understanding the risk factors associated with SBO following these types of surgeries is imperative for improving patient outcomes. OBJECTIVE The objective of this study was to evaluate the incidence of and risk factors for early small bowel obstruction (SBO) after hysterectomy for benign indications. MATERIALS AND METHODS This was a retrospective cohort study using data from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database from 2014 to 2016. Current Procedural Terminology codes were used to identify patients undergoing hysterectomy for benign indications with or without concomitant colpopexy, lysis of adhesions (LOA), adnexectomy, or appendectomy. Data on patient demographics and clinical and surgical factors were obtained. Patients were then stratified into those with and those without SBO. Pairwise comparison was performed using the Wilcoxon rank-sum test and Fisher exact tests. Multivariable logistic regression was used to identify significant independent predictors of SBO. RESULTS Of 47,937 hysterectomies, SBO occurred in 286 patients, at a rate of 5.9 per 1000 hysterectomies. Comparing patients with and without SBO, those with an obstruction were older (49 vs 46 years, P <.001) and were more likely to smoke (21.0% vs 15.8%, P = .02), to have a history of prior abdominal surgery (73.4% vs 65.4%, P = .005), and to have medical comorbidities such as hypertension and dyspnea. Patients experiencing SBO were also more likely to undergo abdominal hysterectomy (72.0% vs 21.2%, P < .001), adhesiolysis (5.2% vs 2.1%, P < .001), appendectomy (1.7% vs 0.5%, P = .02), and cystotomy repair (1.0% vs 0.3%, P = .002). After logistic regression, route of hysterectomy was not a significant risk factor for SBO, whereas wound class ≥3 (adjusted odds ratio [aOR], 5.96; 95% confidence interval [CI], 2.71-12.99) and perioperative transfusion (aOR, 5.01; 95% CI, 3.54-7.13) were the most significant risk factors. Additional risk factors for early SBO included nonwhite race (aOR, 1.84; 95% CI, 1.33-2.48), increasing age (aOR, 1.04; 95% CI, 1.02-1.05), prior abdominal or pelvic surgery (aOR, 1.49; 95% CI, 1.17-2.03), operating times >170 minutes (aOR, 1.90; 95% CI, 1.37-2.58), uterine weight >250 g (aOR, 1.54; 95% CI, 1.11-2.14), lysis of adhesions (aOR, 2.10; 95% CI, 1.23-3.66), and concurrent appendectomy (aOR, 2.64; 95% CI, 1.06-6.65). CONCLUSION Early SBO is a rare complication of benign hysterectomy. Although route of hysterectomy was not found to be a significant risk factor for early SBO, variables typically associated with abdominal hysterectomy compared to minimally invasive hysterectomy, including higher wound class, larger uteri, and perioperative transfusion (a marker of intraoperative blood loss), were strongly correlated with subsequent development of early obstruction.

Abstract
BACKGROUND Adhesive bowel obstruction is associated with considerable morbidity and mortality, but the magnitude of the risk is debated. METHOD In a national cohort of all Danish women with an abdominal operation (N = 665,423) between 1977 and 2013, the risk of adhesive bowel obstruction was assessed by Cox multiple regression. Covariates were the number of abdominal operations, the surgical methods, the anatomical site involved, and the calendar year. RESULTS In the cohort, 1.4% experienced an episode of adhesive bowel obstruction. The risk increased 33-43% during the study period, was lower after gynecological and obstetrical procedures compared to gastrointestinal (HR 0.36 [0.34-0.38]), lower after laparoscopic compared to laparotomic surgery (HR 0.51 [0.48-0.54]) and increased proportionally after each additional operation. CONCLUSIONS The risk of adhesive bowel obstruction after abdominal operations depends on the site of earlier operations, the method of access and the number of earlier operations.

Abstract
BACKGROUND The American Association for the Surgery of Trauma (AAST) anatomic severity grading system for adhesive small bowel obstruction (ASBO) has demonstrated to be a valid tool in North American patient populations. Using a multi-national patient cohort, we retrospectively assessed the validity the AAST ASBO grading system and estimated disease severity in a global population in order to correlate with several key clinical outcomes. METHODS Multicenter retrospective review during 2012-2016 from four centers, Minnesota USA, Bologna Italy, Pietermaritzburg South Africa, and Bucharest Romania, was performed. Adult patients (age ≥ 18) with ASBO were identified. Baseline demographics, physiologic parameters, laboratory results, operative and imaging details, outcomes were collected. AAST ASBO grades were assigned by independent reviewers. Univariate and multivariable analyses with odds ratio (OR) and 95% confidence intervals (CIs) were performed. RESULTS There were 789 patients with a median [IQR] age of 58 [40-75] years; 47% were female. The AAST ASBO grades were I (n = 180, 23%), II (n = 443, 56%), III (n = 87, 11%), and IV (n = 79, 10%). Successful non-operative management was 58%. Conversion rate from laparoscopy to laparotomy was 33%. Overall mortality and complication and temporary abdominal closure rates were 2, 46, and 4.7%, respectively. On regression, independent predictors for mortality included grade III (OR 4.4 95%CI 1.1-7.3), grade IV (OR 7.4 95%CI 1.7-9.4), pneumonia (OR 5.6 95%CI 1.4-11.3), and failing non-operative management (OR 2.4 95%CI 1.3-6.7). CONCLUSION The AAST EGS grade can be assigned with ease at any surgical facility using operative or imaging findings. The AAST ASBO severity grading system has predictive validity for important clinical outcomes and allows for standardization across institutions, providers, and future research. Disease severity and outcomes varied between countries. LEVEL OF EVIDENCE III Study type Retrospective multi-institutional cohort study.

Abstract
Background Adhesive small bowel obstruction (ASBO) is a common surgical emergency, causing high morbidity and even some mortality. The adhesions causing such bowel obstructions are typically the footprints of previous abdominal surgical procedures. The present paper presents a revised version of the Bologna guidelines to evidence-based diagnosis and treatment of ASBO. The working group has added paragraphs on prevention of ASBO and special patient groups. Methods The guideline was written under the auspices of the World Society of Emergency Surgery by the ASBO working group. A systematic literature search was performed prior to the update of the guidelines to identify relevant new papers on epidemiology, diagnosis, and treatment of ASBO. Literature was critically appraised according to an evidence-based guideline development method. Final recommendations were approved by the workgroup, taking into account the level of evidence of the conclusion. Recommendations Adhesion formation might be reduced by minimally invasive surgical techniques and the use of adhesion barriers. Non-operative treatment is effective in most patients with ASBO. Contraindications for non-operative treatment include peritonitis, strangulation, and ischemia. When the adhesive etiology of obstruction is unsure, or when contraindications for non-operative management might be present, CT is the diagnostic technique of choice. The principles of non-operative treatment are nil per os, naso-gastric, or long-tube decompression, and intravenous supplementation with fluids and electrolytes. When operative treatment is required, a laparoscopic approach may be beneficial for selected cases of simple ASBO.Younger patients have a higher lifetime risk for recurrent ASBO and might therefore benefit from application of adhesion barriers as both primary and secondary prevention. Discussion This guideline presents recommendations that can be used by surgeons who treat patients with ASBO. Scientific evidence for some aspects of ASBO management is scarce, in particular aspects relating to special patient groups. Results of a randomized trial of laparoscopic versus open surgery for ASBO are awaited.

Abstract
Peritoneal adhesions remain a major public health problem despite the development of laparoscopy. The rules of microsurgery must be known and followed during any pelvic surgery, even in patients who no longer have a desire for pregnancy. Anti-adhesion products are numerous. All have interest, confirmed by anatomical studies showing a smaller extent or a lesser severity of adhesions associated with their use. No studies, however, show clinical benefit in terms of improved pain or postoperative fertility. Pneumoperitoneum parameters, humidification, and lower abdominal pressure should be optimized to limit peritoneal trauma. Peri-operative corticosteroids, whose benefit has been has been demonstrated in at least one randomized trial, should be systematically used.

Abstract
PURPOSE OF REVIEW The negative impact of postoperative adhesions has long been recognized, but available options for prevention remain limited. Minimally invasive surgery is associated with decreased adhesion formation due to meticulous dissection with gentile tissue handling, improved hemostasis, and limiting exposure to reactive foreign material; however, there is conflicting evidence on the clinical significance of adhesion-related disease when compared to open surgery. Laparoscopic surgery does not guarantee the prevention of adhesions because longer operative times and high insufflation pressure can promote adhesion formation. Adhesion barriers have been available since the 1980s, but uptake among surgeons remains low and there is no clear evidence that they reduce clinically significant outcomes such as chronic pain or infertility. In this article, we review the ongoing magnitude of adhesion-related complications in gynecologic surgery, currently available interventions and new research toward more effective adhesion prevention. RECENT FINDINGS Recent literature provides updated epidemiologic data and estimates of healthcare costs associated with adhesion-related complications. There have been important advances in our understanding of normal peritoneal healing and the pathophysiology of adhesions. Adhesion barriers continue to be tested for safety and effectiveness and new agents have shown promise in clinical studies. Finally, there are many experimental studies of new materials and pharmacologic and biologic prevention agents. SUMMARY There is great interest in new adhesion prevention technologies, but new agents are unlikely to be available for clinical use for many years. High-quality effectiveness and outcomes-related research is still needed.

Abstract
BACKGROUND The endometrial carcinoma (EC) is the most frequently occurring female genital cancer. The authors performed this network meta-analysis to compare operative time and the incidence of bowel injury and wound infection of 3 operative approaches (laparoscopy, laparotomy, and laparoscopic-assisted vaginal hysterectomy [LAVH]) in the treatment of EC. METHODS The Cochrane Library, PubMed, and Embase databases were searched. Randomized controlled trials (RCTs) for EC from the day of databases establishment to February 2017 were included. Direct and indirect evidences were combined to calculate the combined weighted mean difference (WMD) or odd ratio values and the surface under the cumulative ranking curve (SUCRA) value of 3 operative approaches in the treatment of EC. RESULTS A total of 9 qualified RCTs were included into the study. The results showed that laparotomy had a shorter-operative time than LAVH (WMD = -40.36, 95% confidence interval = -75.03 to -2.57). However, there was no significant difference in the incidence of bowel injury and wound infection among 3 operative approaches. Besides, the SUCRA values indicated that laparotomy had the shortest operative time but the incidence of bowel injury and wound infection was relatively higher. CONCLUSION The results from this study indicate that laparotomy had highest incidence of bowel injury and wound infection but shortest operative time among 3 operative approaches in the treatment of EC.

Abstract
OBJECTIVE The aim of the current study was to laparoscopically investigate the effects of peritoneal nonclosure on the sites, types, and degrees of adhesions developed after primary caesarean section (CS) in women complaining of secondary infertility after first CS delivery. STUDY DESIGN This was a cross-sectional study, where 250 women suffering from secondary infertility after their first CS had been recruited. They had been classified into group I (n = 89), where both the visceral and parietal peritoneum had been left opened; group II (n = 75), where only the parietal peritoneum had been closed; and group III (n = 86), where both peritoneal layers had been closed. Laparoscopy had been used to classify those adhesions according to the location, severity, and their adverse impact on the reproductive capacity. RESULTS Both adnexal and nonadnexal adhesions had been found significantly higher in group I, while adnexal types of adhesions were significantly higher after nonclosure of the visceral peritoneum in group II. Laparoscopic tubal surgery performed included tubo-ovariolysis, fimbrioplasty, and neosalpingostomy. Pregnancy rate was found correlating with the adnexal adhesion location and score. CONCLUSION Nonclosure of the peritoneum in CS is associated with more adhesion formation, which might adversely affect the future women reproduction.

Abstract
OBJECTIVE Radical trachelectomy combined with pelvic lymphadenectomy has been used to treat early stage cervical cancer patients who wish to preserve their fertility. Although vaginal, abdominal, laparoscopic, and robotic approaches have been used during this procedure, all of these approaches cause peritoneal damage, which could result in periadnexal adhesion. The aim of the present study was to introduce and discuss a novel fertility-preserving option, extraperitoneal radical trachelectomy with pelvic lymphadenectomy. METHODS To minimize peritoneal damage, we developed a new surgical approach for radical trachelectomy combined with pelvic lymphadenectomy. All surgical procedures associated with radical trachelectomy and pelvic lymphadenectomy were performed via an extraperitoneal approach. During this procedure, the uterine arteries, inferior hypogastric nerve, and pelvic splanchnic nerve were preserved. RESULTS Extraperitoneal nerve-sparing radical trachelectomy with pelvic lymphadenectomy was performed in 3 Japanese women with International Federation of Gynecology and Obstetrics stage IA2 and IB1 cervical cancers. In all patients, complete resection of the disease was achieved without causing any intraoperative complications. Although an infected lymphocele developed in a patient that was managed conservatively, no severe postoperative complications were noted. No adjuvant treatments were given, and the patients are currently free of disease. CONCLUSIONS To the best of our knowledge, this is the first report about extraperitoneal radical trachelectomy in patients with early stage cervical cancer. Extraperitoneal radical trachelectomy combined with pelvic lymphadenectomy can be safely performed. Because peritoneal damages, which can cause periadnexal adhesion, could be avoided, we consider that this surgical approach may be an ideal treatment option for women with early stage cervical cancer who wish to preserve their fertility.

Abstract
OBJECTIVE To evaluate if improvement of laparoscopic skills can reduce postoperative peritoneal adhesion formation in a clinical setting. STUDY DESIGN We retrospectively evaluated 25 women who underwent laparoscopic myomectomy from January 1993 to June 1994 and 22 women who underwent laparoscopic myomectomy from March 2002 to November 2004. Women had one to four subserous/intramural myomas and received surgery without antiadhesive agents or barriers. Women underwent second-look laparoscopy for assessment of peritoneal adhesion formation 12 to 14 weeks after myomectomy. Adhesions were graded according to the Operative Laparoscopy Study Group scoring system. The main variable to be compared between the two cohorts was the proportion that showed no adhesions at second-look laparoscopy. RESULTS Demographic and surgical characteristics were similar between the two cohorts. No complications were observed during surgery. No adverse events were recorded during postoperative course. At second-look laparoscopy, a higher proportion of adhesion-free patients was observed in women who underwent laparoscopic myomectomy from March 2002 to November 2004 (9 out of 22) compared with women who underwent the same surgery from January 1993 to June 1994 (3 out of 25). CONCLUSION The improvement of surgeons' skills obtained after ten years of surgery can reduce postoperative adhesion formation.

Abstract
Postoperative adhesions remain one of the more challenging issues in surgical practice. Although peritoneal adhesions occur after every abdominal operation, the density, time interval to develop symptoms, and clinical presentation are highly variable with no predictable patterns. Numerous studies have investigated the pathophysiology of postoperative adhesions both in vitro and in vivo. Factors such as type and location of adhesions, as well as timing and recurrence of adhesive obstruction remain unpredictable and poorly understood. Although the majority of postoperative adhesions are clinically silent, the consequences of adhesion formation can represent a lifelong problem including chronic abdominal pain, recurrent intestinal obstruction requiring multiple hospitalizations, and infertility. Moreover, adhesive disease can become a chronic medical condition with significant morbidity and no effective therapy. Despite recent advances in surgical techniques, there is no reliable strategy to manage postoperative adhesions. We herein review the pathophysiology and clinical significance of postoperative adhesions while highlighting current techniques of prevention and treatment.

Abstract
Although materials and modern surgical techniques have been developed to suppress postoperative adhesions, adhesion formation can still occur, and thus, a novel effective anti-adhesion drug is greatly needed. In the present study, we explored the efficacy of paeoniflorin treatment against postoperative peritoneal adhesions and examined the anti-oxidative stress and anti-inflammatory properties of PE. Forty-eight male Sprague-Dawley rats were randomly divided into 6 groups for the study: the sham, control, hyaluronan and three concentrations (10, 20 and 40 mg/kg/d) paeoniflorin groups. Abdominal adhesions were created by abrasion of the caecum and its opposite abdominal wall. In the paeoniflorin groups, the rats were administered daily oral doses of paeoniflorin for 7 days. The abdominal cavities of the rats were reopened with a U-shaped incision to macroscopically grade the adhesions. Histologic analysis was performed, and oxidative stress, inflammatory cytokine, collagen fiber degradation and cytokeratin levels were measured. Macroscopic and histopathological measurements revealed that paeoniflorin reduced peritoneal adhesion and inflammation. Notably, treatment with paeoniflorin reduced the protein levels of TGF-β1, IL-6 and COX-2. The collagen fiber fractions were distinctly lower in the PE groups than in the control group. Western blotting analyses showed that paeoniflorin increased MMP-9 and superoxide dismutase-2 protein expression and sharply reduced α-SMA and COX-2 protein expression. Peritoneal mesothelium cells were more continuous and complete in animals treated with paeoniflorin. Our study suggests that paeoniflorin can be used to ameliorate peritoneal adhesions via anti-oxidative stress and anti-inflammatory actions during the postoperative period.

Abstract
Purpose Post-surgical adhesions remain a significant concern following abdominopelvic surgery. This study was to assess safety, manageability and explore preliminary efficacy of applying a degradable hydrogel adhesion barrier to areas of surgical trauma following gynecologic laparoscopic abdominopelvic surgery. Methods This first-in-human, prospective, randomized, multicenter, subject- and reviewer-blinded clinical study was conducted in 78 premenopausal women (18–46 years) wishing to maintain fertility and undergoing gynecologic laparoscopic abdominopelvic surgery with planned clinically indicated second-look laparoscopy (SLL) at 4–12 weeks. The first two patients of each surgeon received hydrogel, up to 30 mL sprayed over all sites of surgical trauma, and were assessed for safety and application only (n = 12). Subsequent subjects (n = 66) were randomized 1:1 to receive either hydrogel (Treatment, n = 35) or not (Control, n = 31); 63 completed the SLL. Results No adverse event was assessed as serious, or possibly device related. None was severe or fatal. Adverse events were reported for 17 treated subjects (17/47, 36.2%) and 13 Controls (13/31, 41.9%). For 95.7% of treated subjects, surgeons found the device “easy” or “very easy” to use; in 54.5%, some residual material was evident at SLL. For 63 randomized subjects who completed the SLL, adjusted between-group difference in the change from baseline adhesion score demonstrated a 41.4% reduction for Treatment compared with Controls (p = 0.017), with a 49.5% reduction (p = 0.008) among myomectomy subjects (n = 34). Conclusion Spray application of a degradable hydrogel adhesion barrier during gynecologic laparoscopic abdominopelvic surgery was performed easily and safely, without evidence of clinically significant adverse outcomes. Data suggest the hydrogel was effective in reducing postoperative adhesion development, particularly following myomectomy.

Abstract
In a prospective study, we investigated the impact of anti-Müllerian hormone (AMH) changes following ovarian cyst surgery on the probability to achieve pregnancy and live birth. Women of reproductive age (n = 60) were included before surgery for benign ovarian cysts. Serum AMH concentrations were determined pre- and postoperative at 6 and 24 months. Information regarding pregnancy wish and attempts to conceive were obtained by a questionnaire. At the time of inclusion, 45/60 women reported desire of children. At six months, the levels of AMH decreased significantly in the whole group and further reduction was observed at two years (from 2.7 μg/L to 2.0 μg/L to 1.1 μg/L, respectively, p< 0.008), with a percentage reduction of 42.9%. At two-year follow-up, 36 women reported to have attempted to conceive and 18 achieved pregnancy (50%), with a live birth rate of 33%. The percentage change in AMH at two years did not differ significantly between the women who conceived versus those who did not (p = 0.117). Data reported herein demonstrate that the AMH reduction following ovarian cyst surgery is maintained two years after surgery; however, the postoperative AMH decrease that follows ovarian cyst surgery might not reduce the chances to achieve pregnancy.

Abstract
We conducted a prospective randomized single blind - subject study in the University Clinic of Gynecology of Pius-Hospital Oldenburg. The primary objective of the ADBEE study was to assess the safety and manageability of ADBLOCK when used as an adjunct to laparoscopic surgery for the primary of myomas in women wishing to improve pregnancy outcomes. The study population included 32 women aged between 18-45 years, in good general health condition, who have not completed their family planning and who are undergoing primary ('virgin') laparoscopic myomectomy with an aim to improve pregnancy outcomes. The patients were randomized in 2 groups, ADBLOCK arm with 21 patients and surgery only arm with 11 patients. The study was single blind - subject and the investigators were blinded to treatment group assignment until completion of uterine suturing and prior to removal of the endoscope. A vigorous follow-up of subjects was organized, focusing on its two critical characteristics: completeness and duration. Completeness represented the percentage of subjects who returned to every planed follow - up appointments. The patients were evaluated in a specific period of time, which defined the duration of follow-up. Safety of the ADBLOCK was estimated after analyzing and documentation of any adverse events occurred, clinical and physical examination of patients as well as evaluation of laboratory measures. There were 25 adverse events reported in ADBLOCK treatment group and 12 events in NO-ADBLOCK group over the 24-months treatment. All adverse events in both treatment arms were not anticipated, with all events in the ADBLOCK group being resolved. At 28 days, there was no significant difference in proportion of events between the two treatments (p = 0.440). Overall, the number of events reported was low and the severity of events was generally mild with an unlikely or no relationship to treatment. There were no unanticipated device related adverse events seen in both treatment groups over the immediate post-operative period or during the 24 months follow up period. By 12 weeks all patients reported their wound as healing well or healed and at 6 months all wounds were reported as healed. There were no differences between both treatment groups regarding the use of painkillers over 24 months follow up period. This clinical first - in - human study, sustained by a rigorous follow-up of the subjects has demonstrated that ADBLOCK is a safe product, presenting no additional safety risk or burden to the patients over surgery alone. The device was relatively easy to use, with a low device failure rate that had no impact on the surgical procedures.

Abstract
OBJECTIVE To provide a comprehensive review of recent epidemiologic data on the burden of adhesion-related complications and adhesion prevention. Second, we elaborate on economic considerations for the application of antiadhesion barriers. BACKGROUND Because the landmark SCAR studies elucidated the impact of adhesions on readmissions for long-term complications of abdominal surgery, adhesions are widely recognized as one of the most common causes for complications after abdominal surgery. Concurrently, interest in adhesion prevention revived and several new antiadhesion barriers were developed. Although these barriers have now been around for more than a decade, adhesion prevention is still seldom applied. METHODS The first part of this article is a narrative review evaluating the results of recent epidemiological studies on adhesion-related complications and adhesion prevention. In part II, these epidemiological data are translated into a cost model of adhesion-related complications and the potential cost-effectiveness of antiadhesion barriers is explored. RESULTS New epidemiologic data warrant a shift in our understanding of the socioeconomic burden of adhesion-related complications and the indications for adhesion prevention strategies. Increasing evidence from cohort studies and systematic reviews shows that difficulties during reoperations, rather than small bowel obstructions, account for the majority of adhesion-related morbidity. Laparoscopy and antiadhesion barriers have proven to reduce adhesion formation and related morbidity. The direct health care costs associated with treatment of adhesion-related complications within the first 5 years after surgery are $2350 following open surgery and $970 after laparoscopy. Costs are about 50% higher in fertile-age female patients. Application of an antiadhesion barriers could save between $328 and $680 after open surgery. After laparoscopy, the costs impact ranges from $82 in expenses to $63 of savings. CONCLUSIONS Adhesions are an important cause for long-term complications in both open and laparoscopic surgery. Adhesiolysis during reoperations seems to impact adhesion-related morbidity most. Routine application of antiadhesion barriers in open surgery is safe and cost-effective. Application of antiadhesion barriers can be cost-effective in selected cases of laparoscopy. More research is needed to develop barriers suitable for laparoscopic use.

Abstract
PURPOSE Risk factors for post-surgical adhesions following gynaecological surgery have been identified, but their relative importance has not been precisely determined. No practical tool exists to help gynaecological surgeons evaluate the risk of adhesions in their patients. The purpose of the study was to develop an Adhesion Risk Score to provide a simple tool that will enable gynaecological surgeons to routinely quantify the risk of post-surgical adhesions in individual patients. METHODS A group of European gynaecological surgeons searched the literature to identify the risk factors and the surgical operations reported as carrying a risk of post-surgical adhesions. Through consensus process of meetings and communication, a four-point scale was then used by each surgeon to attribute a specific weight to each item and collective agreement reached on identified risk factors and their relative importance to allow construct of a useable risk score. RESULTS Ten preoperative and 10 intraoperative risk factors were identified and weighed, leading to the creation of two sub-scores to identify women at risk prior to and during surgery. The Preoperative Risk Score can range from 0 to 36, and the Intraoperative Risk Score from 3 to 31. Several thresholds between these limits may be used to identify women with low, medium, and high risk of post-surgical adhesions. CONCLUSIONS Gynaecological surgeons are encouraged to use this Adhesion Risk Score to identify the risk of adhesions in their patients. This will allow better informed use of available resources to target preventive measures in women at high risk of post-surgical adhesions.

Effectiveness of complementary pain treatment for women with deep endometriosis through Transcutaneous Electrical Nerve Stimulation (TENS): randomized controlled trial. Eur J Obstet Gynecol Reprod Biol 2015; 194:1-6. [PMID: 26319650 DOI: 10.1016/j.ejogrb.2015.07.009] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2015] [Revised: 07/03/2015] [Accepted: 07/23/2015] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Evaluate TENS effectiveness as a complementary treatment of chronic pelvic pain and deep dyspareunia in women with deep endometriosis. STUDY DESIGN This randomized controlled trial was performed in a tertiary health care center, including twenty-two women with deep endometriosis undergoing hormone therapy with persistent pelvic pain and/or deep dyspareunia. This study was registered in the Brazilian Record of Clinical Trials (ReBEC), under n RBR-3rndh6. TENS application for 8 weeks followed a randomized allocation into two groups: Group 1 - acupuncture-like TENS (Frequency: 8Hz, pulse duration: 250μs) - VIF (n=11) and Group 2 - self-applied TENS (Frequency: 85Hz, pulse duration: 75μs) (n=11). The intensity applied was "strong, but comfortable". We evaluated patients before and after treatment by the use of the Visual Analogue Scale, Deep Dyspareunia Scale and Endometriosis Quality of Life Questionnaire. We used the Wilcoxon and Mann-Whitney tests to compare before and after treatment conditions. RESULTS Despite the use of hormone therapy for 1.65±2.08 years, the 22 women with deep endometriosis sustained pelvic pain complaints (VAS=5.95±2.13 and 2.45±2.42, p<.001) and/or deep dyspareunia (DDS=2.29±0.46 and 1.20±1.01, p=.001). We observed significant improvement for chronic pelvic pain, deep dyspareunia and quality of life by the use of TENS. Both application types of TENS were effective for improving the evaluated types of pain. CONCLUSIONS Both resources (acupuncture-like TENS and self-applied TENS) demonstrated effectiveness as a complementary treatment of pelvic pain and deep dyspareunia, improving quality of life in women with deep endometriosis regardless of the device used for treatment.
