BACKGROUND The magnetic compression technique has been used to establish an animal model of tracheoesophageal fistula(TEF),but the commonly shaped magnets present limitations of poor homogeneity of TEF and poor model control.We designed a Tshaped magnet system to overcome these problems and verified its effectiveness via animal experiments.AIM To investigate the effectiveness of a T-shaped magnet system for establishing a TEF model in beagle dogs.METHODS Twelve beagles were randomly assigned to groups in which magnets of the Tshaped scheme(study group,n=6)or normal magnets(control group,n=6)were implanted into the trachea and esophagus separately under gastroscopy.Operation time,operation success rate,and accidental injury were recorded.After operation,the presence and timing of cough and the time of magnet shedding were observed.Dogs in the control group were euthanized after X-ray and gastroscopy to confirm establishment of TEFs after coughing,and gross specimens of TEFs were obtained.Dogs in the study group were euthanized after X-ray and gastroscopy 2 wk after surgery,and gross specimens were obtained.Fistula size was measured in all animals,and then harvested fistula specimens were examined by hematoxylin and eosin(HE)and Masson trichrome staining.RESULTS The operation success rate was 100%for both groups.Operation time did not differ between the study group(5.25 min±1.29 min)and the control group(4.75 min±1.70 min;P=0.331).No bleeding,perforation,or unplanned magnet attraction occurred in any animal during the operation.In the early postoperative period,all dogs ate freely and were generally in good condition.Dogs in the control group had severe cough after drinking water at 6-9 d after surgery.X-ray indicated that the magnets had entered the stomach,and gastroscopy showed TEF formation.Gross specimens of TEFs from the control group showed the formation of fistulas with a diameter of 4.94 mm±1.29 mm(range,3.52-6.56 mm).HE and Masson trichrome staining showed scar tissue formation and hierarchical structural disorder at the fistulas.Dogs in the study group did not exhibit obvious coughing after surgery.X-ray examination 2 wk after surgery indicated fixed magnet positioning,and gastroscopy showed no change in magnet positioning.The magnets were removed using a snare under endoscopy,and TEF was observed.Gross specimens showed well-formed fistulas with a diameter of 6.11 mm±0.16 mm(range,5.92-6.36 mm),which exceeded that in the control group(P<0.001).Scar formation was observed on the internal surface of fistulas by HE and Masson trichrome staining,and the structure was more regular than that in the control group.CONCLUSION Use of the modified T-shaped magnet scheme is safe and feasible for establishing TEF and can achieve a more stable and uniform fistula size compared with ordinary magnets.Most importantly,this model offers better controllability,which improves the flexibility of follow-up studies. 展开更多

BACKGROUND The goal of therapy for traumatic carotid-cavernous fistula(TCCF)is the elimination of fistula while maintaining patency of the parent artery.The treatment for TCCF has evolved from surgery to endovascular management using detachable balloons,coils,liquid embolic agents,covered stents,or flow-diverter stent through arterial or venous approaches.Despite the withdrawal of detachable balloons from the market in the United States since 2004,transarterial embolization with detachable balloons has currently remained the best initial treatment for TCCF in several countries.However,the pseudoaneurysm formation following transarterial detachable balloon embolization has rarely been observed in long-term follow-up.AIM To determine the occurrence and long-term follow-up of pseudoaneurysm after transarterial detachable balloon for TCCF.METHODS Between January 2009 and December 2019,79 patients diagnosed with TCCF were treated using detachable latex balloons(GOLDBAL)of four sizes.Pseudoaneurysm sizes were stratified into five grades for analysis.Initial and follow-up assessments involved computed tomography angiography at 1 month,6 month,1 year,and longer intervals for significant cases.Clinical follow-ups occurred semi-annually for 2 years,then annually.Factors analyzed included sex,age,fistula size and location,and balloon size.RESULTS In our cohort of 79 patients treated for TCCF,pseudoaneurysms formed in 67.1%,with classifications ranging from grade 0 to grade 3;no grade 4 or giant pseudoaneurysms were observed.The majority of pseudoaneurysms did not progress in size,and some regressed spontaneously.Calcifications developed in most large pseudoaneurysms over 5-10 years.Parent artery occlusion occurred in 7.6%and recurrent fistulas in 16.5%.The primary risk factors for pseudoaneurysm formation were identified as the use of specific balloon sizes,with balloon SP and No.6 significantly associated with its occurrence(P=0.005 and P=0.002,respectively),whereas sex,age,fistula size,location,and the number of balloons used were not significant predictors.CONCLUSION Pseudoaneurysm formation following detachable balloon embolization for TCCF is common,primarily influenced by the size of the balloon used.Despite this,all patients with pseudoaneurysms remained asymptomatic during long-term follow-up. 展开更多

BACKGROUND Enterocutaneous fistula(ECF)is an abnormal connection between the gastrointestinal tract and the skin.ECF can lead to massive body fluid loss,hypercatabolism,and malnutrition.Therefore,nutritional support plays a crucial role in managing ECFs and promoting the healing of fistulas.For nutritional support,enteral nutrition(EN)is the preferred method when gastrointestinal function is recovering.Currently,various EN approaches have been applied for different anatomical positions of the ECF.However,the effectiveness of administering EN support for treating lower ECFs still needs further exploration and improvement.CASE SUMMARY We present the case of a 46-year-old male who underwent gastrointestinal stromal tumour resection.Six days after the surgery,the patient presented with fever,fatigue,severe upper abdominal pain,and septic shock.Subsequently,lower ECFs were diagnosed through laboratory and imaging examinations.In addition to symptomatic treatment for homeostasis,total parenteral nutrition support was administered in the first 72 h due to dysfunction of the intestine.After that,we gradually provided EN support through the intestinal obstruction catheter in consideration of the specific anatomic position of the fistula instead of using the nasal jejunal tube.Ultimately,the patient could receive optimal EN support via the catheter,and no complications were found during the treatment.CONCLUSION Nutritional support is a crucial element in ECF management,and intestinal obstruction catheters could be used for early EN administration. 展开更多

BACKGROUND Previous studies have validated the efficacy of both magnetic compression and surgical techniques in creating rabbit tracheoesophageal fistula(TEF)models.Magnetic compression achieves a 100%success rate but requires more time,while surgery,though less frequently successful,offers rapid model establishment and technical maturity in larger animal models.AIM To determine the optimal approach for rabbit disease modeling and refine the process.METHODS TEF models were created in 12 rabbits using both the modified magnetic compression technique and surgery.Comparisons of the time to model establishment,success rate,food and water intake,weight changes,activity levels,bronchoscopy findings,white blood cell counts,and biopsies were performed.In response to the failures encountered during modified magnetic compression modeling,we increased the sample size to 15 rabbit models and assessed the repeatability and stability of the models,comparing them with the original magnetic compression technique.RESULTS The modified magnetic compression technique achieved a 66.7%success rate,whereas the success rate of the surgery technique was 33.3%.Surviving surgical rabbits might not meet subsequent experimental requirements due to TEF-related inflammation.In the modified magnetic compression group,one rabbit died,possibly due to magnet corrosion,and another died from tracheal magnet obstruction.Similar events occurred during the second round of modified magnetic compression modeling,with one rabbit possibly succumbing to aggravated lung infection.The operation time of the first round of modified magnetic compression was 3.2±0.6 min,which was significantly reduced to 2.1±0.4 min in the second round,compared to both the first round and that of the original technique.CONCLUSION The modified magnetic compression technique exhibits lower stress responses,a simple procedure,a high success rate,and lower modeling costs,making it a more appropriate choice for constructing TEF models in rabbits. 展开更多

Introduction: Prevention of obstetric fistula (OF) remains a challenge in Chad where its incidence is 464 cases/year. The present study aims to determine the knowledge and attitudes of nursing staff towards obstetric fistula. Patients and Method: This was a cross-sectional, descriptive and analytical study including nursing staff at the Abéché University Hospital. The survey took place from March to May 2023 and the sampling was exhaustive. Data collection was done using a form including a questionnaire on sociodemographic parameters, knowledge and attitudes. Participation in the study was voluntary and individual. Results: Participation in the study was 76.11%. Emergency department staff were the most represented, followed by gynecology-obstetrics staff with 34.4% and 20.91% of cases respectively. Nurses represented 53.17% of participants followed by doctors (23.52%). An exact definition of obstetric fistula was reported by 7.84% of participants and it was partial in 80.39%. The level of knowledge of risk factors was considered good in 12.41%. Exact knowledge of clinical signs was reported by 74.5% of cases. Among the participants, 1.96% reported that the treatment of obstetric fistula is traditional. Knowledge about means of prevention was considered good by 13.72% (n = 21), and attitudes by 26.79%? Obstetric fistula knowledge was influenced by profession (doctor, p = 0.011) and attitudes by service (p = 0.004) and profession (doctor, p = 0.001). Conclusion: Obstetric fistula is a curable disease whose prevention remains possible and requires good knowledge of the disease and the promotion of safe motherhood. This study should serve as a basis for the establishment of the obstetric fistula module in the curriculum of healthcare personnel and the promotion of continuing training for its eradication. 展开更多

Introduction: Obstetric fistula (OF) is an abnormal communication between the genital and urinary tracts and/or associated with a recto-vaginal communication resulting from prolonged dystocic delivery. It is a frequent pathology in underdeveloped countries. In Zinder no study has been carried out on obstetric fistula. The aim of this study was to evaluate the epidemiological, social impact and therapeutic aspects of obstetric fistula at the CSME of Zinder. Patient and Method: This was a descriptive cross-sectional study of obstetric fistula care at CSME during the period of (January 2018 to June 2020). Results: A total of 196 cases were collected over 30 months. This represents an annual incidence of 78.4 fistulas. The median age of the patients was 18.63 years, and more than 65% were over 20 years old. One hundred and ninety-one patients (97.45%) did not attend school, and 56.12% (n = 110) lived in polygamous households. One hundred and fifty-one women (n = 151), 77.04% had full assistance from their husband during the first four (4) months of the pathology. Twenty-four (12.24%) had been notified of repudiation. Obstetrical risk of dystocia was found in 39.79% (n = 78) of the patients, of whom 24.49% (n = 48) had a focused antenatal consultation (CPNR). The labour lasted more than 24 hours in 100%. The majority of women are multiparous and 60% had at least 2 pregnancies. vesicovaginal fistula is the main pathological type with 86.23%. Fistulas were closed in 83.16% and 68.87% exited without urine loss. Conclusion: Obstetric fistula is a devastating disease affecting girls and young women in Niger, as in other countries in Africa and Asia. It is a major concern worldwide and is a social tragedy because it is disabling and depressing. 展开更多

It is a major public health problem in developing countries. Objective: Study the epidemiology and treatment of obstetric fistulas at the Departmental University Hospital Centre of Borgou and Alibori (CHUD-B/A) in Parakou, Benin. Study Method: This was a descriptive and analytical cross-sectional study with prospective data collection on women treated during OF care missions from February 2020 to April 2021 in CHUD-B/A in Parakou, Benin. The data concerned their socio-demographic characteristics, obstetric history, the clinic and therapeutic characteristics of their obstetric fistulas. Results: In total 97 patients with OF were treated during the 14-month period. The average age of the patients was 36.42 ± 11.75 years old. The patients were married (51.54%), without professional occupation (54.64%) and had no formal education (73.20%). The vesico-vaginal variety was predominating (54.64%). The fistulas were of Type I (46.39%), Type II (20.62%) and Type III (32.99%) according to the classification of Waaldjik Kees. The patients were operated on under spinal anesthesia (94.79%), and vaginally (55.67%) according to the principle of Chassar Moir (68, 60%). The associated procedures were lengthening urethroplasty (17.53%), and interposition of the Martius flap (1.03%). The overall success rate without Stress Urinary Incontinence was 71.13%. The factors associated with the failure of the fistula repair were: the nutritional status of the patients (p = 0.004), the previous repair failure (p = 0.001), the high size of the fistula (p = 0.007), the fistula severity (p and a urethral reconstruction (p Conclusion: OF is a relatively frequent pathology in Benin. Vesico-vaginal fistula is the most common form. The success rate of the surgical treatment is satisfactory, but depends on some factors. 展开更多

Every minute, a woman dies in pregnancy, and for every woman who dies 20 - 30 others will survive with morbidity, one of which is obstetrical fistula. Women who suffer from obstetric fistula experience continuous incontinence of urine and/or stool, stigma, social isolation and associated health problems. The World Health Organization estimates that there are currently more than 2 million women living with untreated obstetric fistula mostly in sub-Saharan Africa and South-East Asia, as well as in various other parts of the world. Caring for fistula patients and nursing them back to full physical and mental health can be one of the most challenging and also rewarding tasks undertaken by nurses. The surgery cannot succeed without proper pre-, peri- and post-operative care. The patients undoubtedly recover better with high-quality care—meaning the truly holistic, generous, and selfless care of a nurse who has the skills, understanding and determination to help these very vulnerable patients. Objective: This research seeks to assess the strategies of obstetric fistula management by nurses/midwives of Yaoundé central hospital and CHU by exploring the care they offer to clients pre-operatively, post-operatively, and when they are discharged from the hospital. Achieving Millennium Development Goal (MDG) 3 still remains a challenge to the developing countries although maternal mortality reduction is a priority agenda of each country. Methodology: This retrospective cross-sectional descriptive study design employed a sample of 100 nurses/midwives on active service, and who have at least managed a case of obstetric fistula. A quantitative questionnaire was used to collect data, which was analyzed using SPSS version 23. Results: The study proved a highly significant difference between management and qualification, with a p-value of 0.002. Also, it showed that there was a statistically significant difference between longevity of service and management with a p-value of 0.001. A majority of respondents were nurse assistants (52%), and up to 43% of respondents had 11 - 20 years of work experience. Up to 53% did not offer standard care with respect to their qualification, and up to 52% did not offer standard care with respect to their longevity in service. Conclusion: VVF is the most common type of obstetric fistula with a frequency of 6 to 10 cases, there is an overall poor management of obstetric fistula by nurses and midwives in YCH and CHU. There is an urgent need to train and retrain these health workers on the management strategies of obstetric fistula and to remind them of their personal commitment as care givers. 展开更多
