Hysteroscopic observations in 348 consecutive cases of female genital tuberculosis: A prospective study

Study objectiveTo evaluate the hysteroscopic findings in female genital tuberculosis.DesignIt was a prospective study of hysteroscopic findings performed on 348 cases of female genital tuberculosis (FGTB).SettingIt was a prospective cross-sectional study in a tertiary referral centre.PatientsA total of 348 patients with infertility with FGTB on various tests.InterventionA total of 348 patients of infertility found to have FGTB on various investigations were enrolled in the study. A detailed history was taken. Clinical examination, endometrial sampling and diagnostic laparoscopy were performed was also performed in selected cases. All patients underwent hysteroscopy as part of evaluation for infertility and tuberculosis (TB) findings.Measurements and main resultsThe mean age, parity, body mass index and duration of infertility was 28.2 years, 0.31,23.1kg/m² and 3.44 years respectively. Infertility was primary in 81.03% and secondary in 18.96% cases. Diagnosis of FGTB was made by endometrial aspirate findings of positive AFB on microscopy (4.02%), positive culture (4.88%), positive PCR (83.90%), epithelioid granuloma (14.65%), positive AFB on microscopy or culture of peritoneal cytology (1.14%) or epithelioid granuloma on peritoneal biopsy (1.72%), definitive findings of TB on laparoscopy (41.95%) or probable findings of TB on laparoscopy (58.05%). Various hysteroscopic findings observed were normal findings (28.16%), pale endometrial cavity (54.31%), features of active TB (7.47%), features of chronic TB (19.54%), features of TB sequelae like obstructed ostia (both ostia in 13.79%, one ostia 14.94%, periostial fibrosis; (bilateral 4.59%, unilateral 5.17%), endometrial glands atrophy (12.35%), small shrunken cavity (6.32%), distorted cavity (5.17%), various grades of intrauterine adhesions (29.88%). Hysteroscopy in FGTB was associated with increased difficulties and complications like failed procedures, difficult visualisation, false passage and uterine perforation.ConclusionHysteroscopy is useful modality to detect endometrial TB but is associated with increased difficulty and complications.     

An evaluation of Composite Reference Standard (CRS) for diagnosis of Female Genital Tuberculosis

BackgroundFemale genital tuberculosis (FGTB) is a common cause of infertility in developing countries. Its diagnosis is difficult due to its paucibacillary nature, with no single test having high sensitivity and specificity. This study is to share the experience of using Composite Reference Standard (CRS) for the diagnosis of FGTB.MethodsThis is a prospective study conducted between September 2017 to June 2019, over 100 infertile females found to have FGTB on composite reference standard which consisted of acid-fast bacilli on microscopy or culture, histopathological evidence of epithelioid granuloma, positive gene Xpert on endometrial sample or definite or probable finding of FGTB on laparoscopy.ResultsA total of 100 infertile women (78% primary, 22% secondary) found to have FGTB on CRS were enrolled in this study. Mean age, body mass index, parity and duration of infertility were 28.2 years, 23.17 kg/m², 0.24 ± 0.12 and 2.41 years respectively. Various symptoms were scanty menses (16%), irregular cycle (7%), dysmenorrhea (11%), pelvic pain (11%). Various signs were vaginal discharge (65%), adnexal mass (6%), tubo-ovarian mass on ultrasound (15%), abnormal hysterosalpingography findings (57.14%), positive polymerase chain reaction test (65%) and abnormal hysteroscopy (82.2%). The positive findings on CRS were positive AFB on microscopy or culture (3%), positive gene Xpert (28%) (done in some cases), epithelioid granuloma on histopathology (13%), definite findings on laparoscopy like tubercles, caseous nodules and beaded tubes in (57.19%) patients while probable findings of FGTB like straw colored fluid in POD, extensive dense pelvic, peri-tubal, peri-ovarian adhesions; hydrosalpinx; tubo-ovarian mass; thick fibrosed tubes; mid tubal block; peri hepatic adhesions (Fitz Hugh Curtis Syndrome); hyperemia of tubes/blue uterus on chromotubation were seen in (48.8%) patients. All patients found to be positive on CRS were given 6 months of anti-tubercular therapy.ConclusionThis study demonstrates the high reliability of use of composite reference standard for diagnosis of FGTB.     

Computed tomographic findings in female genital tuberculosis tubo-ovarian masses

Female genital tuberculosis (FGTB) is a common cause of infertility in developing countries. It can manifest as menstrual disturbances, infertility and pelvic masses.ObjectiveTo evaluate the role of computed tomography in diagnosis of female genital tuberculosis with tubo-ovarian (adnexal) masses.MethodsIt was a prospective study over a four year period (July 2015 to August 2019) in a tertiary referral centre over 33 patients presenting with tuberculosis and tubo ovarian masses only. 75 total cases of FGTB diagnosed on composite reference standard (evaluation of AFB bacilli in microscopy or culture or endometrial biopsy, gene expert, epitheloid granulomas on endometrial biopsy or definitive or possible findings of FGTB on laparoscopy). Detailed history taken, clinical examination, baseline investigations and endometrial biopsy were done in all cases. Computed tomography was performed in women presenting with infertility, tubo ovarian masses on clinical examination and laboratory investigations. A total of 33 cases were evaluated.ResultsMean age, body mass index, parity and history of TB contact were 27.5 ± 4.2 year, 22.7 ± 3.6 kg/m², 0.27 ± 0.13 and 44.4% respectively. Infertility was primary in 72.72% and secondary in 27.23%. Case wise mean duration being 5.8 years, menstrual dysfunction was seen in 45.45% cases. Abdominal discomfort with pain and lump were seen in all 33 (100%) cases. Abdominal lumps were felt in 4 (12.12%) cases while adnexal mass was seen in all 33 (100%) cases being unilateral in 18 (54.54%) and bilateral in 15 (45.45%). Mean ESR was 33.4mm in first hour while mean leucocyte count was 6128 ± 2854 per cubic mm. Infectious mantoux test (>10mm) was seen in 14 (42.82%) cases while abnormal X ray chest was seen in 9 (27.27%) cases.Diagnosis of FGTB was made by positive AFB n microscopy or culture of endometrial biopsy in 5 (15.15%) cases, positive gene expert in 6 (18.18%) cases, positive polymerase chain reaction in 32 (96.96%) cases, epitheloid granulomas on histopathology of endometrial biopsy in 7 (21.21%) cases, definitive findings of tuberculosis in 15 (45.45%) cases and a possible findings of tuberculosis inn 18 (54.54%) cases. Various CT findings were pelvic mass (100%), unilateral pelvic mass in 18 (54.54%), bilateral pelvic mass in 15 (45.45%), cystic mass (24.2%), solid mass (21.2%), mixed mass (54.54%), mass showing multilocular caseous necrotic enhancements (12.12%), ascites (42.4%), thickening and enhancement of peritoneum in 14 (42.42%), nodules in 24.2%, smooth in 18.8%, pelvic adhesion in 6 (18.18%), lymphadenopathy in 8 (24.3%) with calcifications (9.09%) and central necrosis (52.5%). Other CT findings were thickening and enhancement of bowel wall (12.12%), hepatic TB (3.03%), splenic TB (3.03%), omental thickening (9.09%) and omental calcification (3.03%) cases.ConclusionComputed tomography appears to be a useful diagnostic modality in diagnosis of tuberculosis tubo ovarian masses and may help avoid unnecessary surgery.     

Tuberculous peritonitis in Egypt: the value of laparoscopy in diagnosis.

Abdominal laparoscopy was performed on 200 patients with undiagnosed ascites. It was unsuccessful in one patient with tuberculous peritonitis because of extensive adhesions. A presumptive diagnosis of tuberculous peritonitis based on clinical findings and peritoneal tubercles or adhesions visualized during laparoscopy was made in 90 of these patients. The diagnosis was confirmed in 88 by histopathology, bacteriology, or therapeutic response. Two of the 109 remaining patients who had other presumptive diagnoses made during laparoscopy were eventually confirmed to be cases of tuberculous peritonitis. Of 91 patients with tuberculous peritonitis included in this series, 79% were females, with the majority (79%) of them being of child-bearing age. Half had been ill for longer than one month. The most frequent complaints were abdominal pain, fever, anorexia, night sweats, abdominal swelling, and weight loss. Ascites, fever, wasting, pallor, and abdominal tenderness were common findings. Ultrasonography demonstrated ascites in all patients who underwent this procedure; 21% also had adhesions. Pleural effusion was present in 15% and pulmonary tuberculosis was detected in only two patients. Biopsy samples taken during laparoscopy showed that 60% had noncaseous granulomas and 33% had caseous granulomas. Mycobacterium tuberculosis was detected in 77%, with guinea pig inoculation having the highest sensitivity, followed by culture, and lastly by acid-fast smear. Mycobacterium tuberculosis was isolated more easily from biopsy samples than from ascitic fluid. Nine of 20 M. tuberculosis isolates that were identified as to species were M. bovis. Tuberculous peritonitis, a frequent cause of febrile ascites in Egyptian women, was easily diagnosed by histopathologic and bacteriologic studies of biopsy samples taken at laparoscopy. All patients responded rapidly to antituberculosis therapy.     

Laparoscopic peritoneal biopsy can be crucial for diagnosis of tuberculous peritonitis

A 28-year-old woman was admitted to a nearby hospital because of low-grade fever and lower abdominal pain, where ascites and slightly elevated serum CA125 level were found. Both acid-fast stain (AFS) and polymerase chain reaction (PCR) failed to detect Mycobacterium tuberculosis in her ascitic fluid, sputum, and gastric juice. She was referred to our division under suspicion of tuberculous peritonitis or ovarian carcinoma. Finally, diagnostic laparoscopy was carried out, showing yellowish-white small nodules disseminated on her whole peritoneum with thin fibrous adhesions. Peritoneal biopsy of these nodules showed epithelioid cell granulomas without caseous necrosis. AFS and PCR again failed to show any evidence of Mycobacterium tuberculosis in these biopsied samples. Based on the laparoscopic findings, however, we thought that she suffered from tuberculous peritonitis. Antituberculous therapy was started and she improved soon. Later, Mycobacterium tuberculosis was demonstrated in the 4-week culture of a peritoneal biopsy specimen. We conclude that laparoscopy may be the only way to detect Mycobacterium tuberculosis in tuberculous peritonitis whenever doubtful but no direct evidence is obtained.     

Correlation of past tuberculosis with current screening for female genital tuberculosis in infertile women in a tertiary care hospital

ObjectivesTo analyse correlation of past history of tuberculosis with present state of infertility with respect to HSG and diagnostic findings, with a view to assess the frequency of genital tuberculosis in infertile women, its clinical presentation and association with infertility.Materials and methodsThe study is an ongoing study conducted in the Department of Obstetrics and Gynaecology, Kasturba Hospital, Delhi and included 174 infertile women enrolled as OPD patients in our hospital. A detailed history with special emphasis on past history of tuberculosis, thorough clinical examination, all routine investigations for Infertility & special investigations for genital tuberculosis was done. Diagnostic tests and laparoscopy was further performed as per the protocol.ResultsFemale genital tuberculosis has been described as a disease of the younger population. The present study shows that 87.9% patients diagnosed for genital tuberculosis were between 20 and 35 yrs of age. It was observed that amongst 174 infertile patients who attended our OPD, 40 patients had a positive history of present or previous incidence of Koch's, pulmonary or extra pulmonary, namely 22.9% (Group I) and the remaining patient comprising 77.1%, who had no record of any previous tuberculosis (Group II). Active Tuberculosis was seen in 5 patients out of a total of 40 females. Out of the total of 174 infertile patients suffering from tubal disorder 52.5% of Group I patients had evidences of tubal disease as compared to only 27.6% in Group II thus suggesting a strong correlation of tubal destruction and subsequent infertility to a positive history of tuberculosis. Out of the 56 laparoscopies performed, it was seen that 75% of Group I patients with past history of TB had abnormal laparoscopic findings (18 out of 24 patients), as compared to Group II which had only 9 out of 32 patients (28%) showing positive pelvic pathology. This seems to be very significant.ConclusionIn conclusion the results of the present study validate arguments in favour of incorporating screening for genital tuberculosis as a part of the baseline investigation for all patients of infertility, in countries like ours and especially in such patients who have suffered from Tuberculosis sometimes earlier in their lives.     

Mycoplasmateceae species are not found in Fallopian tubes of women with tubo-peritoneal infertility

BackgroundThe role of mycoplasmas on the development and sequelae of pelvic inflammatory disease remains controversial. The objective of the present study is to correlate directly the presence of Mycoplasmateceae through polimerase chain reaction (PCR) determinations in cervix and Fallopian tubes of infertile patients with tubo-peritoneal factor diagnosed through laparoscopy.MethodsThirty patients with tubo-peritoneal infertility and 30 normal fertile patients were included in the study; cervical samples and tubal flushings were obtained during laparoscopy. PCR determinations for the detection of genetic material of Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealiticum, Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis in cervix and tubal flushings were performed.ResultsNo Mycoplasmataceae species as “only” microorganisms were found in tubal flushings of tubo-peritoneal infertility patients, whereas three (10%) fertile patients with normal tubes were positive for mycoplasma presence. This difference was not significant (p = 0.237). Among the 30 patients suffering from tubal infertility diagnosed through laparoscopy, Mycoplasmatecae species were not detected in the Fallopian tubes by PCR determinations, while in normal tubes from fertile patients these and other microorganisms could be found without distorting tubal anatomy.ConclusionMycoplasmateceae species were not detected in Fallopian tubes of women with tubo-peritoneal infertility.     

Peritoneal tuberculosis with negative polymerase chain reaction results: report of two cases

Peritoneal tuberculosis is rarely observed in European countries. We report on peritoneal tuberculosis in two female immigrants from Somalia and Columbia who presented with diffuse abdominal pain, fever, weight loss and exudative, lymphocytic ascites. Laboratory investigations showed an increase in C-reactive protein and carcinoma antigen 125 serum levels. Nodular peritoneal lesions and adhesions were detected by ultrasound and computed tomography. In both patients, peritoneal biopsy from laparoscopy revealed epitheloid granulomas with central necrosis and multinucleate giant cells. Microscopy and PCR analysis were, however, negative for Mycobacterium tuberculosis in both patients. Despite repeated testing, ascites culture became positive for M. tuberculosis in only one patient. Shortly after starting antituberculous drug treatment, both patients improved, ascitic fluid disappeared and C-reactive protein and carcinoma antigen 125 serum levels returned to normal. Even in Western countries, peritoneal tuberculosis should be considered in any febrile patient with abdominal signs and symptoms, particularly if ascites is present. Empirical antituberculous treatment is justified in patients with clinical and histological features highly suggestive of peritoneal tuberculosis, even in cases with negative results from microscopy, culture and PCR analysis.     

Peritoneal macrophages from patients with endometriosis release growth factor activity in vitro

We studied the in vitro secretion of macrophage-derived growth factor (MDGF) activity by peritoneal macrophages from fertile and infertile women. Peritoneal fluid was obtained from 55 women undergoing laparoscopy for evaluation and treatment of infertility or for tubal sterilization. Isolated macrophages were plated in tissue culture wells and incubated in Dulbecco's Modified Eagle's Medium plus 0.2% lactalbumin hydrolyzate at 37 C for 24 h. Medium MDGF activity was assayed by determining the ability of medium to stimulate [3H] thymidine incorporation in BALB-c 3T3 fibroblasts. Macrophages from 23 women released significant MDGF activity in vitro; the release was linear for up to 72 h. Among the 55 women, macrophages from 10 of 36 (28%) women with normal pelvic anatomy or tubal occlusion/pelvic adhesions released significant MDGF activity. In contrast, macrophages from 13 of 19 (68%) women with endometriosis, a significantly higher proportion (P less than 0.02), released MDGF. The finding that endometriosis is associated with in vivo primed peritoneal macrophages that produce MDGF in vitro may help to explain the proliferation or maintenance of endometrial tissue in the peritoneal cavity.     

Peritoneal Tuberculosis: Laparoscopic Patterns and Its Diagnostic Accuracy

We report laparoscopic findings in 38 proven cases of peritoneal tuberculosis. The laparoscopic appearances can be classified into three types: thickened peritoneum with miliary yellowish white tubercles with or without adhesions (n = 25), only thickened peritoneum with or without adhesions (n = 8), and fibroadhesive pattern (n = 5). Biopsies were avoided from fibroadhesive lesions due to risk of complications. Visual diagnosis was accurate in 95% of patients. In comparison, in 27 (82%) of 33 patients, the examination enabled a histologic diagnosis to he made on the basis of typical granulomas. The combined use of guinea pig inoculation and culture isolated Mycobacterium tuberculosis in six (37.5%) of 16 patients. Mycobacteria were scarcely (3%) seen on histological sections. We conclude that, although target biopsy is an effective method of obtaining an early diagnosis of peritoneal tuberculosis, chemotherapy may be started on the basis of visual laparoscopic appearances alone.     

What is the role of diagnostic laparoscopy in a gastroenterology unit?

Background Diagnostic laparoscopy is known to be a relatively safe invasive procedure. However, its use has decreased owing to the development of imaging techniques, and fewer gastroenterologists now practice diagnostic laparoscopy. Our aim was to examine the role of diagnostic laparoscopy in a gastroenterology unit in the era of advanced imaging techniques. Methods We retrospectively reviewed 855 diagnostic laparoscopy cases. Its safety and efficacy were evaluated for various indications. Results No mortality was observed, and complications were noted in ten patients (1.2%). Among the indications were evaluation of chronic liver disease (n = 673), liver tumor (n = 15), ascites of unknown origin and peritoneal disease (n = 142), and staging of intra-abdominal malignancy (n = 25). In patients with chronic liver disease, 461 were diagnosed as having chronic viral hepatitis, based on clinical data including imaging studies, but the diagnosis was changed to cirrhosis after a laparoscopic exam in 69 patients (15.0%). In patients with ascites of unknown origin and peritoneal disease, the diagnostic yield was 87.2% (123/141). In 24 (19.5%) of the 123 patients, the diagnosis changed or the less probable diagnosis was confirmed after laparoscopic examination. The confirmed diagnoses were mainly primary peritoneal disease, including peritoneal tuberculosis, in 17 patients, peritoneal metastatic carcinoma in five, and mesothelioma in two. Conclusions Diagnostic laparoscopy in a gastroenterology unit is safe and useful, especially for confirmation of liver cirrhosis and primary peritoneal disease evaluation.     

Peritoneal adhesions after laparoscopic gastrointestinal surgery

Although laparoscopy has the potential to reduce peritoneal trauma and post-operative peritoneal adhesion formation,only one randomized controlled trial and a few comparative retrospective clinical studies have addressed this issue.Laparoscopy reduces de novo adhesion formation but has no efficacy in reducing adhesion reformation after adhesiolysis.Moreover,several studies have suggested that the reduction of de novo post-operative adhesions does not seem to have a significant clinical impact.Experimental data in animal models have suggested that CO2 pneumoperitoneum can cause acute peritoneal inflammation during laparoscopy depending on the insufflation pressure and the surgery duration.Broad peritoneal cavity protection by the insufflation of a low-temperature humidified gas mixture of CO2,N2O and O2 seems to represent the best approach for reducing peritoneal inflammation due to pneumoperitoneum.However,these experimental data have not had a significant impact on the modification of laparoscopic instrumentation.In contrast,surgeons should train themselves to perform laparoscopy quickly,and they should complete their learning curves before testing chemical anti-adhesive agents and antiadhesion barriers.Chemical anti-adhesive agents have the potential to exert broad peritoneal cavity protection against adhesion formation,but when these agents are used alone,the concentrations needed to prevent adhesions are too high and could cause major postoperative side effects.Anti-adhesion barriers have been used mainly in open surgery,but some clinical data from laparoscopic surgeries are already available.Sprays,gels,and fluid barriers are easier to apply in laparoscopic surgery than solid barriers.Results have been encouraging with solid barriers,spray barriers,and gel barriers,but they have been ambiguous with fluid barriers.Moreover,when barriers have been used alone,the maximum protection against adhesion formation has been no greater than 60%.A recent small,randomized clinical trial suggested that the combination of broad peritoneal cavity protection with local application of a barrier could be almost 100%effective in preventing post-operative adhesion formation.Future studies should confirm the efficacy of this global strategy in preventing adhesion formation after laparoscopy by focusing on clinical end points,such as reduced incidences of bowel obstruction and abdominal pain and increased fertility.     

The Princess Margaret Hospital study of ovarian cancer: stages I, II, and asymptomatic III presentations.

An analysis of 231 patients with stages I, II, and asymptomatic III ovarian cancer, studied in a prospective randomized-stratified trial, is presented. None of the stage IA patients with well-differentiated tumors have had disease relapses; one fourth of the patients with poorly differentiated tumors have had disease relapses throughout the peritoneal cavity. There is therefore little justification for pelvic radiation alone as postoperative therapy for stage IA ovarian carcinoma. For stage IB, II, and asymptomatic III presentations, patients with an incomplete initial pelvic operation had poor survival characteristics with all tested therapies. For patients in whom the operation was completed, abdominopelvic radiation was superior to pelvic radiation alone or followed by chlorambucil, with respect to long-term survival and control of abdominal disease. The effectiveness of abdominopelvic radiation was independent of stage or histology. The value of abdominopelvic radiation was most strikingly seen in patients with no visible residual tumor.     

Effect of hyaluron derivate gel in prevention of postsurgical peritoneal adhesions--an experimental study in pigs

BACKGROUND/AIMS: The aim of this study was to assess the efficacy of a hyaluronic acid derivate gel in reducing adhesions in pigs undergoing laparoscopic abdominal cavity surgery. METHODOLOGY: 20 domestic female pigs underwent laparoscopy in general anesthesia. 4 defined serosal defects have been made (hepatoduodenal ligament, parietal, anterior stomach wall and jejunal mesentery). The defects have been covered with 20 mL Hyalobarrier Gel in 10 randomly selected pigs. 2 weeks postoperatively the pigs got reoperated for evaluation of potential adhesions. RESULTS: 17 pigs remained for evaluation. 2 pigs died during introduction of anesthesia, one at the end of the operation. None of the pigs died due to a reaction to the gel. We found adhesions in 33% of the gel group (n=3 out of 9) and in 87.5% in the group without gel (7 out of 8): p < 0.05. Most of the adhesions have been found at the parietal defect (7 out of 17 at all). CONCLUSIONS: The hyaluronic acid gel was highly efficacious and reduced the number and extent of adhesions throughout the abdomen following laparoscopic peritoneal surgery significantly.     

A 41 year-old female with abdominal pain and fever of 24 hours

A 41 year-old female with intrauterine contraceptive device (ICD) from 8 year ago that complained fever and abdominal pain during 24 hours and leucocytosis. The radiology examination tests showed cegal, appendiceal, and right ovary enlargement with swollen of fat adjacent. In the differential diagnosis should be include: appendicitis, diverticulitis, chronic inflammatory digestive disease or mesenterical adenitis. In the differential diagnosis included: ovarian neoplasm, endometriosis, ectopic pregnancy, ovarian torsion and pelvic inflammatory diseases. From pelvic infections, it is import consider pelvic inflammatory disease, genital tuberculosis and pelvic actinomycosis. With the antecedent of ICD, the clinic and the radiological finding as abdominal mass with invasion of adjacent structures and absence of adenopathy; the first diagnosis is a abdominopelvic actinomycosis and the second is a genital tuberculosis.     

Intraperitoneal cell movement during abdominal carbon dioxide insufflation and laparoscopy

PURPOSE: Possible mechanisms of movement of malignant cells within the peritoneal cavity during CO₂ insufflation and laparoscopy involve direct transfervia laparoscopic instruments or dispersion of cells by CO₂ or water vapor. Anin vivo model has been developed to study these mechanisms. METHODS: Laparoscopy was performed on an animal model (domestic white pig). Cells derived from colorectal cancer cell line Lim 1215 were injected to lie free within the peritoneal cavity. A polycarbonate filter system with a 5-micron pore diameter was used to examine CO₂ expelled from the peritoneal cavity, during laparoscopy and manipulation of abdominal viscera, for malignant cells. Laparoscopic instruments and laparoscopic ports were washed independently, and fluid was centrifuged and examined for malignantcells. RESULTS: Malignant cells were identified on 1 of 30 filters used to examine exhaust carbon dioxide. Malignant cells also were identified from 2 of 10 washings from laparoscopic ports and from 4 of 10 washings of laparoscopic instruments. CONCLUSIONS: These results suggest that movement of cells throughout the peritoneal cavity during laparoscopy isvia contaminated instruments, but local cell movement by dispersion possibly within water vapor from the port may also occur.     

Effect assessment of laparoscopy in combination with traditional Chinese medicine decoction in the treatment of endometriosis: A protocol for systematic review and meta-analysis

Background:Endometriosis (EMs) affects about 10% of women of childbearing age. It is defined as functional endometrial tissue appearing in other parts of the uterine cavity, manifested by varying degrees of pelvic pain and pelvic mass, etc. Therefore, to improve the therapeutic effect of endometriosis, we must constantly explore new ways to treat the disease. The purpose of this study is to evaluate the effectiveness and safety of the combined use of laparoscopy and traditional Chinese medicine in the treatment of patients with EMs.Methods:A systematic literature search will be conducted at China National Knowledge Infrastructure, WanFang databases, VIP, SinoMed, PubMed, Embase, Web of Science, and the Cochrane library. The search period limit is from the time the date of database establishment to June 21, 2021. To ensure the comprehensiveness of the search, relevant references and conference literature are also included. The risk of bias in the final included studies will be evaluated based on the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. The RevMan software will be employed to perform data synthesis and statistical analysis.Results:The effectiveness and safety of laparoscopic surgery combined with traditional Chinese medicine decoction in the treatment of patients with EMs will be systematically evaluated.Conclusion:The results of this study will provide strong evidence for judging whether laparoscopy combined with traditional Chinese medicine decoction is an effective strategy for the treatment of patients with EMs.     

Role of laparoscopy in diagnosing genital tuberculosis in suspected women: A cross-sectional study from a tertiary care hospital in Northern India

This study was included 60 women with suspected genital tuberculosis, attending outpatient department of a tertiary care hospital. The aim was to evaluate the role and accuracy of laparoscopy in the diagnosis of genital tuberculosis. The patients were investigated for tuberculosis with Erythrocyte Sedimentation Rate, Montoux, chest X-ray, serum ELISA, CA125, ultrasonography, endometrial biopsy and laparoscopic biopsy. Culture or histopathology was taken as a gold standard for confirming the cases of genital tuberculosis. 30 patients were confirmed as positive. Comparison was made between the various diagnostic modalities. Baseline investigations like complete blood count, differential leukocyte count, ESR, Montoux, and some special tests like CA125 and serum ELISA were helpful in supporting the diagnosis in only some patients. The sensitivity, specificity, positive and negative predictive value of endometrial biopsy in diagnosing GT was 6.6%, 100%, 100% and 51.7% respectively. Laparoscopic gross visualization alone, staining, culture and histology were able to detect 86.6%, 33.3%, 50% and 63.3% of cases respectively. Many patients would have been missed if laparoscopy was not performed. It helps in macroscopic visualization of pelvic cavity and obtaining biopsies for ZN staining, culture and histopathology. This increases the pickup rate of positive cases and helps in confirmation of the diagnosis.     

Shone's syndrome: Insights from three‐dimensional echocardiography

Shone's syndrome is a rare congenital anomaly defined as the presence of at least two of the following heart obstructions: a mitral supravalvular ring, a “parachute” mitral valve stenosis, subaortic stenosis, and aortic coarctation. A 58‐year‐old man presented with a mitral ring and a “parachute” mitral valve on two‐dimensional transthoracic echocardiography, raising suspicion of Shone's syndrome. Three‐dimensional transesophageal echocardiography revealed a subannular mitral ring inserted directly on the mitral leaflets, thus acting as a “valvar ring.” This distinction can have therapeutic implications as a “valvar” mitral ring could require valve repair or replacement, instead of simple resection.     

Prevention of postoperative peritoneal adhesions: Effects of lysozyme,polylysine and polyglutamate versus hyaluronic acid

Objective. Intraperitoneal adhesions are an important cause of postoperative intestinal obstruction, abdominal discomfort and infertility. In the present study we hypothesized that a combination of polypeptides with different surface properties, resulting in fine disperse low-soluble complexes, could be of benefit in the prevention of abdominal adhesions.Material and methods. Various polypeptides including lysozyme, polyglutamate, polylysine and combinations of all three were evaluated as compared to hyaluronic acid. A standard wound on the parietal peritoneum in mice was used and the evaluated agents were administered immediately postoperatively. The extent of peritoneal adhesions to the injured area was measured and expressed as a percentage of the wound length as evaluated after 7 days. Flow cytometry was performed to evaluate the effect on peritoneal macrophage survival and phagocytic function and the Pick test was used to determine peroxide production in order to estimate toxicity and potential impairment of macrophage function caused by the chemicals.Results. Significant differences were seen among the treatment groups (p<0.001). Both polyglutamate and lysozyme, and polyglutamate together with polylysine significantly decreased adhesion formation as compared to hyaluronic acid. The polylysine–polyglutamate combination was still visible macroscopically on the peritoneal surface after 1 week, though not after 1 month. The polyglutamate–lysozyme mixture was less effective than these individual components alone. The chemicals did not show any toxic effects or altered function in macrophage cell culture.Conclusions. Lysozyme, polyglutamate and, most effectively, a polyglutamate–polylysine combination significantly decreased experimental abdominal adhesion formation. A strong mechanical connection to the wound and prolonged attendance in the surface were noted. Peritoneal phagocyte function did not seem to be influenced by the chemicals.
