Outcome of Laparoscopic Adhesiolysis in Infertile Patients with Pelvic Adhesions Following Cesarean Delivery: A Randomized Clinical Trial.

OBJECTIVES: To evaluate results of laparoscopic adhesiolysis in patients with post cesarean infertility regards restoration of the fertility and achievement of pregnancy. To identify a group of patients who should primarily be offered laparoscopic adhesiolysis and those who should be treated by IVF. DESIGN: Randomized prospective clinical trial MATERIALS AND METHODS: 184 patients with secondary infertility diagnosed to have periadnexal and pelvic adhesions, were randomly allocated into two groups: group I (92 cases) treated by laparoscopic adhesiolysis and group II (92 cases) who treated for a year by controlled ovarian stimulation and IUI up to 3 trials. Diagnostic work-up of infertility was carried out denoting normal semen, patent both tubes at HSG, and ovulatory at ovulation testing with normal hormonal profile. The outcomes, cumulative pregnancy rates calculated for each group after one year. RESULTS: According to the adhesions, the patients classified into 4 groups: 8 cases inoperable, 43 cases with mild type adhesions, 26 cases with moderate type adhesions, and 5 cases with severe type adhesions. The patients followed up postoperatively for year. Overall pregnancy rate 54.35 %. For patients with mild adhesions 76.7%, for patients with moderate adhesions 61.5%, and for patients with severe adhesions 20%. Complications present in (1.57%), cost is (125.7-180.9 $). Over all pregnancy rate was 11.96% in group (II) CONCLUSIONS: laparoscopic adhesiolysis is the method of choice for dealing with mild to moderate periadnexal adhesions after C.S. The pregnancy outcome after lysis of severe periadnexal adhesions is poor. So, such patients are best treated by IVF.

Labial Adhesion: New Classification and Treatment Protocol.

STUDY OBJECTIVE: To determine the subtypes of labial adhesion (LA) and arrange treatment options accordingly. DESIGN AND SETTING: Patients who presented to our clinic with LA between July 2016 and February 2018 were divided into 4 groups. Location of the adhesion area, thickness of the adhesive tissue, and response to topical steroid (betamethasone valerate 0.1% ointment) therapy were identified as common features. PARTICIPANTS: Seventy-five prepubertal girls. INTERVENTIONS AND MAIN OUTCOME MEASURES: To determine the subtypes of the LA and evaluate the treatment response of patients in each subtype group. RESULTS: LA was divided into 4 subtypes according to their common characteristics. For patients with type I, 2 weeks of topical steroid treatment resulted in complete recovery (100%). For those with type II, 12 (80%) patients had complete response to topical steroid treatment for an average of 3 weeks. Type III and IV patients were completely unresponsive to topical steroid treatment. CONCLUSION: Classification of LA patients into subtypes and determination of treatment on the basis of this classification make a major contribution in planning the treatment of patients, not by trial-and-error, but using a predetermined strategy.

Prediction of pelvic adhesions at repeat cesarean delivery through assessment of striae gravidarum score: A cross-sectional study.

OBJECTIVE: To investigate the predictive value of the Davey Score for striae gravidarum (SG) on the presence of pelvic adhesions at repeat cesarean delivery (CD). MATERIALS AND METHODS: The current study was a cross-sectional study conducted in a tertiary university hospital between November 2016 and March 2018. All women scheduled for elective CD were included if they had at least previous one CD with pregnancy in term fetus (37-40 weeks gestation. Preoperative evaluation of SG severity using Davey score, which is a validated scoring system, was done on the examination bed. Patients with no/mild striae (score 0-2) were classified as group (I) and women with severe striae (score 3-8) were classified as group (II). During surgery, pelvic adhesions were evaluated and classified according to the Nair's scoring system. The primary outcome was the difference in the rate of pelvic adhesions between both groups. RESULTS: The study included 300 women; group I included 114 women and group II included 186 women. About 90% of women with severe striae versus 82.5% of women with no/mild striae were found to have adhesions (p = 0.035). Dense adhesions were significantly present in severe striae group (57.4%) versus (41.5%) in no/mild striae group (p = 0.022). The mean Davey score in women in group (II) was significantly higher than group (I) (4.25 ± 3.36 vs. 3.09 ± 2.95, p = 0.03). Nair's score had a significant positive moderate correlation with Davey score (r = 0.541, p = 0.016). According to the results of multivariate regression analysis, Davey score >2 was the only variable associated with increased risk of pelvic adhesions (p = 0.010). CONCLUSION: Assessment of SG score in women with previous CD using Davey score might help to predict pelvic adhesions status before planning a new surgery.

PERITONEAL ADHESIONS TYPE I, III AND TOTAL COLLAGEN ON POLYPROPYLENE AND COATED POLYPROPYLENE MESHES: EXPERIMENTAL STUDY IN RATS.

BACKGROUND: Hernia correction is a routinely performed treatment in surgical practice. The improvement of the operative technique and available materials certainly has been a great benefit to the quality of surgical results. The insertion of prostheses for hernia correction is well-founded in the literature, and has become the standard of treatment when this type of disease is discussed. AIM: To evaluate two available prostheses: the polypropylene and polypropylene coated ones in an experimental model. METHODS: Seven prostheses of each kind were inserted into Wistar rats (Ratus norvegicus albinus) in the anterior abdominal wall of the animal in direct contact with the viscera. After 90 days follow-up were analyzed the intra-abdominal adhesions, and also performed immunohistochemical evaluation and videomorphometry of the total, type I and type III collagen. Histological analysis was also performed with hematoxylin-eosin to evaluate cell types present in each mesh. RESULTS: At 90 days the adhesions were not different among the groups (p=0.335). Total collagen likewise was not statistically different (p=0.810). Statistically there was more type III collagen in the coated polypropylene group (p=0.039) while type I was not different among the prostheses (p=0.050). The lymphocytes were statistically more present in the polypropylene group (p=0.041). CONCLUSION: The coated prosthesis was not different from the polypropylene one regarding the adhesion. Total and type I collagen were not different among the groups, while type III collagen was more present on the coated mesh. There was a greater number of lymphocytes on the polypropylene mesh.

Determination of therapeutic strategy for adhesive small bowel obstruction using water-soluble contrast agents: An audit of 776 cases in a single center.

BACKGROUND: Several studies have investigated the diagnostic and therapeutic role of water-soluble contrast agents in adhesive small bowel obstruction, but there is no clear diagnostic classification for the determination of therapeutic strategy. The aim of this study was to clarify the clinical value of classification using water-soluble contrast agents in patients with adhesive small bowel obstruction. METHODS: Between January 2009 and December 2015, 776 consecutive patients with adhesive small bowel obstruction were managed initially with water-soluble contrast agents and were included in the study. Abdominal x-rays were taken 5 hours after administration of 100 mL water-soluble contrast agents and classified into 4 types. The medical records of the patients with adhesive small bowel obstruction were analyzed retrospectively and divided into 2 groups of patients with complete obstruction (ie, the absence of contrast agent in the colon) with (type I) or without (type II) a detectable point of obstruction and a group with an incomplete obstruction (ie, the presence of contrast agent in the colon) with (type IIIA) or without (type IIIB) dilated small intestine. RESULTS: Types I, II, IIIA, and IIIB were identified in 27, 90, 358, and 301 patients, respectively. The overall operative rate was 16.6%. In the patients treated conservatively (types IIIA and IIIB), 647 patients (98.2%) were treated successfully without operative intervention. The operative rate was 3.4% (n = 12/358) in type IIIA vs 0% (n = 0/301) in the type IIIB group (P = .001). Compared with type IIIA, type IIIB was associated with earlier initiation of oral intake (2.1 vs 2.6 days, P < .001) and a lesser hospital stays (9 vs 11 days, P < .001). CONCLUSION: This new classification using water-soluble contrast agents is a simple and useful diagnostic method for the determination of therapeutic strategy for adhesive small bowel obstruction.

Schinus terebinthifolius raddi (Aroeira) and Orbignya phalerata mart. (Babassu) effect in cecorrahphy healing in rats.

PURPOSE: To evaluate the effect of Schinus terebinthifolius Raddi (aroeira) and Orbignya phalerata Mart. (babassu) in the healing process of cecorrhaphy in rats. METHODS: : Fifty four rats were used, distributed into three groups randomly: aroeira, babassu and control, which were divided into three subgroups (six animals) according to the time of the deaths (7, 14, 21 days). All underwent the same surgical procedure, cecotomy and cecorrhaphy. The animals in group aroeira and babassu received daily dose of 100 mg/kg of hydroalcoholic extract and 50 mg/kg of aquous extract respectively, by gavage. The control group received only saline solution. The parameters evaluated were: macroscopic changes, ,resistance test to air insufflations and histological changes. RESULTS: : All animals showed good healing without infection. All groups presented adhesions between cecum and neighboring organs. The resistance test insufflating of atmospheric air showed progressive increase of pressure according to the days in the aroeira group, and decrease in babassu group, without significant difference. Microscopy showed significant difference in the polymorphonuclear, hyperemia, angiogenesis, fibroblast proliferation and collagen histological variables in the 14th day. CONCLUSION: : Hydroalcoholic extract of aroeira and the aqueous extract of babassu favored the healing process in cecorrhaphy in rats.

The design and validation of an optical coherence tomography-based classification system for focal vitreomacular traction.

PURPOSE: To develop and validate a classification system for focal vitreomacular traction (VMT) with and without macular hole based on spectral domain optical coherence tomography (SD-OCT), intended to aid in decision-making and prognostication. METHODS: A panel of retinal specialists convened to develop this system. A literature review followed by discussion on a wide range of cases formed the basis for the proposed classification. Key features on OCT were identified and analysed for their utility in clinical practice. A final classification was devised based on two sequential, independent validation exercises to improve interobserver variability. RESULTS: This classification tool pertains to idiopathic focal VMT assessed by a horizontal line scan using SD-OCT. The system uses width (W), interface features (I), foveal shape (S), retinal pigment epithelial changes (P), elevation of vitreous attachment (E), and inner and outer retinal changes (R) to give the acronym WISPERR. Each category is scored hierarchically. Results from the second independent validation exercise indicated a high level of agreement between graders: intraclass correlation ranged from 0.84 to 0.99 for continuous variables and Fleiss' kappa values ranged from 0.76 to 0.95 for categorical variables. CONCLUSIONS: We present an OCT-based classification system for focal VMT that allows anatomical detail to be scrutinised and scored qualitatively and quantitatively using a simple, pragmatic algorithm, which may be of value in clinical practice as well as in future research studies.

Vitreomacular traction syndrome: postoperative functional and anatomic outcomes.

BACKGROUND AND OBJECTIVE: To analyze a variety of vitreomacular traction (VMT) morphologies to establish a major classification that better reflects the preoperative predictive factors of postoperative visual and anatomic outcomes. PATIENTS AND METHODS: Thirty-six eyes submitted to vitrectomy surgery were categorized with a VMT pattern (V- or J-shaped) and diameter (focal < 1,500 µm or broad > 1,500 µm) based on optical coherence tomography. RESULTS: The researchers compared different classifications of VMT. Despite similar postoperative best corrected visual acuity (BCVA) values (P = .393), cases with focal VMT had greater visual improvement (P = .027) because the preoperative BCVA was significantly lower in the focal group (P = .007). However, the BCVA improvements did not differ between the groups regarding the classic VMT morphologic patterns (P = .235). CONCLUSION: Postoperative outcomes and macular disorders are closely related to VMT size. The adhesion diameter (focal or broad VMT) and not the classic VMT morphologic pattern (V- or J-shaped) may better predict the postoperative anatomic and functional outcomes.

Spectrum of morphological and visual changes due to vitreomacular interface disorders encountered in a large consecutive cohort of patients.

AIM: Identify the incidence of vitreomacular traction (VMT) and frequency of reduced vision in the absence of other coexisting macular pathology using a pragmatic classification system for VMT in a population of patients referred to the hospital eye service. METHODS: A detailed survey of consecutive optical coherence tomography (OCT) scans was done in a high-throughput ocular imaging service to ascertain cases of vitreomacular adhesion (VMA) and VMT using a departmental classification system. Analysis was done on the stages of traction, visual acuity, and association with other macular conditions. RESULTS: In total, 4384 OCT scan episodes of 2223 patients were performed. Two hundred and fourteen eyes had VMA/VMT, with 112 eyes having coexisting macular pathology. Of 102 patients without coexisting pathology, 57 patients had VMT grade between 2 and 8, with a negative correlation between VMT grade and number of Snellen lines (r=-0.61717). There was a distinct cutoff in visual function when VMT grade was higher than 4 with the presence of cysts and sub retinal separation and breaks in the retinal layers. CONCLUSIONS: VMT is a common encounter often associated with other coexisting macular pathology. We estimated an incidence rate of 0.01% of VMT cases with reduced vision and without coexisting macular pathology that may potentially benefit from intervention. Grading of VMT to select eyes with cyst formation as well as hole formation may be useful for targeting patients who are at higher risk of visual loss from VMT.

The clinical characteristics and new classification of sticky eyelid syndrome in East Asian patients.

PURPOSE: The aim of this study was to demonstrate the characteristics of sticky eyelid syndrome (SES) and to suggest a modified definition and new classification of the disease in relation to the severity of the syndrome in East Asian patients. METHODS: Forty-four eyes of 31 patients with sticky eyelid syndrome were included in this study. The medical records of patients who were diagnosed with sticky eyelid syndrome were retrospectively reviewed. Sticky eyelid syndrome was defined as an abnormal adhesion between the upper and lower eyelids during blinking. We divided the subjects into four grades according to the severity of the disease. RESULTS: Among 31 patients, there were 10 men and 21 women. The mean age of patients was 62.5 years. A total of 13 patients had SES bilaterally. All patients had meibomian gland dysfunction (MGD). Thirty-three eyes had dermatochalasis, and 30 eyes had involutional ptosis. Horizontal lower lid laxity was observed in 23 eyes, and reverse ptosis found in 15 eyes. Patients were classified into four groups as follows: G1: 11 (25%), G2: 24 (54.5%), G3: 6 (13.6%) and G4: 3 eyes (6.8%). Patients in Grade 1 tended to improve only with medical treatment for MGD. However, surgical management was necessary for patients in Grades 3 and 4. CONCLUSIONS: Meibomian gland dysfunction is a fundamental risk factor for developing sticky eyelid syndrome. Further, combined upper lid ptosis or lower lid laxity may be aggravating factors. According to the grading, medical or surgical management can be chosen.

Generator pocket adhesions of cardiac leads: classification and correlation with transvenous lead extraction results.

OBJECTIVES: Pacemaker (PM) and implantable cardioverter defibrillator (ICD) leads become encapsulated intravascularly and in the generator pocket by fibrotic adhesions that accumulate over time. These adhesions are responsible for the difficulty and risk of lead extraction procedures. We developed a classification scheme for pocket adhesions, classified all of the patients in the cohort, and examined the relationship between pocket adhesions and the outcome of the procedure. METHODS: The classification of adhesions with respect to the intraoperative adhesion coverage was as followed: class 0 = adhesion free; class 1 ≤ 30% of adhesion coverage; class 2 = 30-60% of adhesion coverage; and class 3 ≥ 60% coverage. Patient data between December 2010 and March 2012 were collected. A total of 100 leads were extracted from 58 patients (1.7 ± 0.8 leads/patient); the mean lead implant duration was 78.5 ± 66.7 months, and the percentage of PM/ICD leads was 68% (n = 68)/32% (n = 32). RESULTS: Distribution of the leads among classes: 0 = 10; 1 = 17; 2 = 25; and 3 = 48. Average implant times (months) according to the adhesion classes: 0 = 1.2 ± 0.4; 1 = 19.8 ± 19.2; 2 = 79.3 ± 46.6; and 3 = 115.1 ± 106.0 (correlation-coefficient 0.71; P ≤ 0.05). Average numbers of extraction tools used according to the adhesions: 0 = none; 1 = 0.4 ± 0.7; 2 = 1.6 ± 1.0; and 3 = 2.3 ± 1.2 (correlation coefficient = 0.67; P ≤ 0.05). Complete removal was achieved in 100% of the patients in classes 0 and 1; 96% in class 2 (n = 24); and 75% in class 3 (n = 36) (P ≤ 0.05). Mortality = 0. CONCLUSIONS: Extensive adhesions in the generator pocket predict the need for a higher number of extraction tools. High-grade pocket adhesions predict lower success rates with regard to complete lead extraction. Both findings suggest that the degree of pocket adhesions predicts the degree of intravascular adhesions.

The relevance of post-cesarean adhesions.

With an increasing number of cesareans and repeat cesarean deliveries, clinicians have started to realize the importance of adhesions after cesarean delivery. Adhesions develop more frequently and with increasing severity with each repeat cesarean, and are associated with increasing maternal morbidity especially bladder injury and increased delivery time. It appears that adhesion formation could be reduced with closure of the peritoneum, double-layer closure of the uterine incision, and the use of adhesion barrier. In many reports of adhesion formation after cesarean delivery, authors have used different methods to evaluate adhesions. We encourage clinicians to adopt a newly published site-specific classification of adhesions after caesarean delivery.

Histologic study of adhesions in the upper joint compartment of the temporomandibular joint.

PURPOSE: The aim of this study was to observe the histologic characteristics of adhesions in the upper joint compartment of the temporomandibular joint and investigate the mechanism of genesis. PATIENTS AND METHODS: During arthroscopic surgery, we obtained 42 biopsy specimens of different grades of adhesions, ranging from grade I to grade IV, from 21 joints in 21 patients with internal derangement. Two biopsy specimens from each temporomandibular joint were obtained in this study; one was immediately fixed in 4% formalin and examined under a light microscope, and the other was fixed in 2% glutaraldehyde solution and examined under a transmission electron microscope. RESULTS: Different grades of adhesions had uniform dense connective tissue under the light microscope, and a number of fibrocytic cells were scattered within the extracellular matrix. However, in grade II adhesions, synovial membrane and some elastic fibers were shown. Under the transmission electron microscope, orderly arranged collagen bundles were prominent in grade I and grade III adhesions. Elastic fibers were abundant in grade II adhesions with orderly arranged collagen bundles; a small number of inactive fibroblasts were scattered about these adhesions. Randomly arranged collagen bundles and elastic fibers were also observed in grade IV adhesions, in which synovial membrane cells and cartilaginoid cells were detected. In addition, fibroblasts with active secretion were observed, and a considerable amount of rough endoplasmic reticulum was noted. CONCLUSIONS: Different arrangements of collagen fibers with or without elastic fibers were observed in the 4 types of adhesions. These findings could enable further exploration into the mechanism of adhesion formation.

Classification--important step to improve management of patients with an open abdomen.

This short report is a distillation of the proceedings from a consensus group meeting in January 2009. It outlines a proposed classification system for patients with an open abdomen (OA). The classification allows (1) a description of the patient's clinical course; (2) standardized clinical guidelines for improving OA management; and (3) improved reporting of OA status, which will facilitate comparisons between studies and heterogeneous patient populations. The following grading is suggested: grade 1A, clean OA without adherence between bowel and abdominal wall or fixity of the abdominal wall (lateralization); grade 1B, contaminated OA without adherence/fixity; grade 2A, clean OA developing adherence/fixity; grade 2B, contaminated OA developing adherence/fixity; grade 3, OA complicated by fistula formation; grade 4, frozen OA with adherent/fixed bowel, unable to close surgically, with or without fistula. We propose that this classification system will facilitate communication, clarify OA management, and potentially improve patient care.

The changes of joint effusion on MRI and arthroscopic findings after visually guided TMJ irrigation correlated to the clinical outcome.

OBJECTIVE: This study aimed to investigate the changes of joint effusion (JE) on the MRI and arthroscopically observed pathology after visually guided TMJ irrigation (VGIR) in patients with chronic closed lock. The correlation of these findings to the clinical outcome was also studied. STUDY DESIGN: Forty patients with unilateral chronic closed lock who underwent 2-time VGIR, were divided into either the good outcome (g-) group (n = 29) or poor outcome (p-) group (n = 11) after the first VGIR. Before each VGIR, the each severity of JE, osteoarthritis, synovitis, and fibrous adhesion were assessed. They were compared between the g- and p-groups, or between the first and second VGIR. RESULTS: The severity of JE at the first VGIR was significantly worse in the p-group. In both groups, JE significantly improved after the first VGIR. In the g-group, synovitis significantly improved after the first VGIR, but fibrous adhesion significantly became worse. CONCLUSIONS: JE may be predictive for the clinical outcome of TMJ irrigation in chronic closed lock patients. Moreover, the severity of JE and arthroscopically observed synovitis could reflect the clinical state to some degree.

Polypropylene mesh covered colonic anastomosis. Results of a new anastomosis technique.

BACKGROUND: The morbidity and mortality rates of anastomosis leakage of the gastrointestinal system, are high. In this study we covered the colonic anastomosis with polypropylene mesh on the safety of the anastomosis was investigated. METHODS: Twenty female albino rabbits were divided into two groups. First of all, a segmental colon resection was performed in both the groups and a single layer of anastomosis was made. In addition, a polypropylene mesh as long as the circumference of the anastomosis in the study group. All the rabbits were sacrificed on the 10th postoperative day and the explosion pressure of the anastomosis, histopathological investigation of the anastomotic contour, and peritoneal adhesion were compared. RESULTS: The anastomoses of all the subjects in the control group had exploded and the average explosion pressure was 149 +/- 16 mmHg. However, in the study group, the anastomoses did not explode in nine (90%) of the subjects, whereas it exploded in only one (10%) with a pressure of 260 mmHg. The average explosion pressure in the study group was 315 +/- 30 mmHg (p < 0.0001). No significant difference was established between the groups according to the histopathological classification of the anastomotic contour performed according to the Ehrlich-Hunt model (p > 0.05). Peritoneal adhesions of the groups is not statistically different (p > 0.05). CONCLUSION: During the short follow-up period, this new technique significantly increased the safety of the anastomosis, moreover it did not cause any increase in peritoneal adhesions. This success has most probably occurred as a result of the external mechanical support to the anastomosis.

Induction and assessment methods used in experimental adhesion studies.

Infertility and intestinal obstruction are well-known complications, arising from adhesion formation after intra-abdominal operations. Basic principles of adhesion formation have been found through animal studies. In addition, examination of agents for the prevention of adhesions can be easily made using experimental studies. However, lack of uniformity in study design makes assessment of the efficacy of any prophylactic regimen difficult. In this review, the material and methods used in experimental studies designed for adhesion formation or prevention were evaluated in detail, with experimental studies published in the literature from 1960 to 2003 being evaluated. Several methods for adhesion induction have been described in the literature. Severity of the adhesion varies from method to method, with the main problem being the lack of uniform expression of study results. Extensive use of complex adhesion classification systems should be used to resolve this discordance between experimental studies.
