To assess the feasibility, safety and efficacy of the use of a fully covered self-expandable stent for the treatment of airway fistula. From August 2005 to November 2011, 9 patients underwent treatment by the introduction of a tracheo-bronchial or bronchial fully covered self-expandable metallic stent. There were 7 males and 2 females, aged from 28-65 years with a mean of 46 years. In this group, 7 cases were diagnosed as bronchopleural fistula, 1 case as tracheopleural fistula, 1 case as broncho-esophageal fistula, 8 cases with thoracic empyema. The fistula orifices were from 3.5-25.0 mm in diameter with a mean 8.4 mm. All patients received topical anesthesia, and L-shaped stent was placed in 6 patients and I-shaped stent in 3 patients under fluoroscopic guidance. After the stent placement, the patients with empyema were treated with continual irrigation of the empyema cavity. Stent placement in the tracheo-bronchial tree was technically successful in all patients, without procedure-related complications. The operating time was from 5-16 minutes, mean time (10 ± 4) minutes. Except for 1 patient, immediate closure of the airway fistula was achieved in the other patients after the procedure, as shown by the immediate cessation of bubbling in the chest drain system or the contrast examination. In this study, 1 patient coughed the inserted stent out due to irritable cough on the 5th day and had to receive repositioning of a new stent. Among the patients who were with empyema, 1 patient died of septicemia on the 8th day and 1 patient died of brain metastases from lung cancer 6 months after the stent insertion with empyema not cured, the other 6 patients' empyema healed from 2-5 months, mean time 3.7 months. Seven patients were followed from 3 to 36 months with a median of 13.5 months. During follow-up, 1 stent was removed from a patient 8 months after the stent implantation without empyema recurred. The remaining patient presented good tolerability to the existence of

Lung suppurative diseases in children are usually responsive to medical treatment or percutaneous drainage. Rarely, pulmonary resection is required for lung abscess in childhood, particularly in presence of co-morbidities. In these cases, a lobectomy is usually performed through an open thoracotomy, with a reported incidence of bronco-pleural fistula up to 9.1% of pediatric series. This consequence is mainly due to the inflammatory condition; however the lack of knowledge of pediatric and thoracic surgeons with this rare condition in childhood can also play a role. In adults with lung cancer, the buttressing of bronchial stump with the additional support of an intercostal muscle (ICM) flap has proved to prevent this complication, as well as to reduce post-operative pain. We report the first pediatric experience of ICM flap used in 2 immunocompetent children requiring lobectomy for suppurative lung conditions. Our preliminary experience confirms the feasibility of protecting the bronchial stump after lobectomy in children, especially in conditions at risk for bronco-pleural fistula development.

In patients with a bronchocutaneous fistula, positive pressure ventilation leads to air leakage and potential hypoxemia. A male patient with a right upper bronchocutaneous fistula was scheduled for esophageal reconstruction. His preoperative chest computed tomography image revealed aeration in the right middle and lower lobe, a large bulla in the left upper lobe, and pleural effusion and pneumonia in the left lower lobe. Therefore, left one-lung ventilation was considered to result in hypoxemia. Before anesthesia induction, the bronchocutaneous fistula was covered with gauze and film to prevent air leakage. After anesthesia induction, mask ventilation was performed with a peak positive pressure of 10 cmH 2 O. A left-sided double lumen endobronchial tube (DLT) was then inserted into the right main bronchus for occluding only the right superior bronchus, and two-lung ventilation was performed to minimize airway pressure and maintain oxygenation, which did not cause air leakage through the fistula. During anesthesia, no ventilation-related difficulty was faced. The method of inserting a left-sided DLT into the right main bronchus and occluding the right upper bronchus selectively by bronchial cuff is considered to be an option for mechanical ventilation in patients with a right upper bronchial fistula, as demonstrated in the present case.

A bronchobiliary fistula (BBF), which is defined by an abnormal communication between the biliary system and the bronchial tree, is an uncommon complication after hemihepatectomy, trauma, hydatid disease, choledocholithiasis and other causes of biliary obstruction. We report the case of a 56-year-old man with colon cancer, who developed a BBF 2 months after right hemihepatectomy for liver metastases. The findings at endoscopic retrograde cholangiopancreaticography (ERCP), computed tomography (CT) and magnetic resonance cholangiography (MRC) included a stricture of the common bile duct and biliary leakage from the liver resection plane with biliary infiltration of the right lower lobe of the lung. The patient was treated successfully by endoscopic insertion of a biliary plastic stent which bridged the stricture and lead to closure of the fistula

Objective: Massive hemoptysis is always a life-threatening respiratory disease and requires emergency management. This study is to evaluate the clinical efficacy and safety of bronchial artery embolization (BAE) by using permanent particles in the management of massive hemoptysis. Methods: Thirty-three patients with massive hemoptysis who had failed to respond to medical management received BAE. The causative diseases included bronchiectasis (n = 24), bronchogenic carcinoma (n = 4), bronchiectasis complicated with tuberculosis (n = 2), bronchial disease (n = 2) and traumatic destroyed lung (n = 1). Embolization with sodium alginate microspheres (KMG) was performed in all patients, and additional use of microcoils was carried out in patients complicated with bronchial-pulmonary fistulae. All patients were followed up for at least 3 months. Results: BAE was successfully accomplished in all patients. The cessation of hemoptysis was immediately obtained in all patients, with a success rate of 100%. Recurrence of hemoptysis within one month after BAE was seen in 3 patients (9.1%, 3/33). No serious complications occurred and the mean postoperative hospitalization days of the patients were 10 days. Conclusion: With satisfactory instant clinical results, BAE by using permanent particles is a safe, effective treatment for the massive hemoptysis. (authors)

Bronchopleural fistula (BPF) is still a life-threatening complication after pulmonary resection. Several factors were identified to contribute BPF. Meticulous surgical technique and the liberal use of prophylactic, pedicled flaps are important for prevention. Although these patients often present compromised and moribund, evaluation and management should proceed in a logical, stepwise fashion. In high-risk surgical patients, bronchoscopic procedures using different glues and sealants may serve as a temporary bridge until the patient's recovery or as a permanent resolution. However persistent conservative therapy may deteriorate patient's condition. Immediate creation of open window thoracotomy has been shown to be a significant predictor of wound closure afterwards. Pedicled muscle or omental flaps are useful to close bronchial stump and to fill the residual space in the thorax after pulmonary resection. Once fistula closed, the pleural space is filled with an antibiotic solution and then the open window thoracotomy closed in layers as Clagett procedure. The transternal transpericardial approach to recalcitrant postpneumonectomy BPF can be considered when patients have failed prior closure attempt. To conclude, survival and excellent result of BPF depends on early diagnosis, and aggressive surgical intervention.

Full Text Available A 7-month-old girl with failure to thrive, who, on clinical and diagnostic evaluation [echocardiography & CT angiography] to rule out congenital heart disease, revealed a rare vascular anomaly called systemic artery to pulmonary venous fistula. In our case, there was dual abnormal supply to the entire left lung as1 anomalous supply by normal systemic artery [internal mammary artery]2 and an aberrant feeder vessel from the abdominal aorta. Left Lung had normal bronchial connections and normal pulmonary vasculature. The fistula drained through the pulmonary veins to the left atrium leading to ‘left–left shunt’. Percutaneous intervention in two stages was performed using Amplatzer vascular plugs and coil embolization to close them successfully. The patient gained significant weight in follow up with other normal developmental and mental milestones.

The purpose of the current study is to present the clinical and surgical results in patients who underwent hybrid video-assisted thoracic surgery with segmental-main bronchial sleeve resection. Thirty-one patients, 27 men and 4 women, underwent segmental-main bronchial sleeve anastomoses for non-small cell lung cancer between May 2004 and May 2011. Twenty-six (83.9%) patients had squamous cell carcinoma, and 5 patients had adenocarcinoma. Six patients were at stage IIB, 24 patients at stage IIIA, and 1 patient at stage IIIB. Secondary sleeve anastomosis was performed in 18 patients, and Y-shaped multiple sleeve anastomosis was performed in 8 patients. Single segmental bronchiole anastomosis was performed in 5 cases. The average time for chest tube removal was 5.6 days. The average length of hospital stay was 11.8 days. No anastomosis fistula developed in any of the patients. The 1-, 2-, and 3-year survival rates were 83.9%, 71.0%, and 41.9%, respectively. Hybrid video-assisted thoracic surgery with segmental-main bronchial sleeve resection is a complex technique that requires training and experience, but it is an effective and safe operation for selected patients.

In the developed world, urethrovaginal fistulas are most the likely the result of iatrogenic injury. These fistulas are quite rare. Proper surgical repair requires careful dissection and tension-free closure. The objective of this video is to demonstrate the identification and surgical correction of an urethrovaginal fistula. The case presented is of a 59-year-old woman with a history of pelvic organ prolapse and symptomatic stress urinary incontinence who underwent vaginal hysterectomy, anterior colporrhaphy, posterior colporrhaphy, and synthetic sling placement. Postoperatively, she developed a mesh extrusion and underwent sling excision. After removal of her synthetic sling, she began to experience continuous urinary incontinence. Physical examination and cystourethroscopy demonstrated an urethrovaginal fistula at the midurethra. Options were discussed and the patient wished to undergo transvaginal fistula repair. The urethrovaginal fistula was intubated with a Foley catheter. The fistula tract was isolated and removed. The urethra was then closed with multiple tension-free layers. This video demonstrates several techniques for identifying and subsequently repairing an urethrovaginal fistula. Additionally, it demonstrates the importance of tension-free closure. Urethrovaginal fistulas are rare. They should be repaired with careful dissection and tension-free closure.

A 67-year-old man suffered a traffic accident and was transferred to an emergency hospital close to the scene. He was diagnosed to have bilateral pneumohemothorax with a lung contusion, an anterior fracture dislocation of the C6-vertebra and a cervical cord injury at the level of C7. On the 48th day, massive hemoptysis was suddenly recognized. He was transferred in a state of shock to our hospital to undergo hemostasis for the bleeding. On the day of admission, a selective arteriogram showed extravasation from the left bronchial artery, for which embolization was carried out using Gelfoam. In spite of this treatment, his hemoptysis continued. On the next day, a selective left internal mammary arteriogram showed an arteriovenous fistula between the left internal mammary artery and the left pulmonary vein without any apparent extravasation. The arteriovenous fistula was successfully embolized using platinum fiber coils. The patient no longer demonstrated any hemoptysis after embolization

The objective of the present work was to search for the tissue and cellular markers of remodeling of bronchial mucosa in the patients with different clinical forms of bronchial asthma (BA). The use of up-to-date morphometric techniques has demonstrated that mild and moderately severe forms of bronchial asthma are accompanied by the development of Th2-immune response associated with increased production of interleukin-4 and marked degranulation of eosinophilic granulocytes resulting in desquamation of epithelium and goblet cell hyperplasia. The severe BA phenotype of "chronic asthma with fixed obstruction" is associated with the development of non-atopic inflammation in the bronchial mucous membrane that manifests itself as the increased concentration of interleukin-8 in bronchial mucosa and its neutrophilic infiltration leading to the development of pronounced subepithelial fibrosis, thickening of the basal membrane, and atrophy of epithelium. Specific structural changes in bronchial mucosa of the patients presenting with BA underlie functional disturbances that cause severe bronchial obstructive syndrome.

Full Text Available The article highlights the results of the act test based bronchial asthma supervision evaluation among teenagers and defines the interrelation of the objective and subjective asthma supervision parameters. The researchers examined 214 male teenagers aged from 16 to 18, suffering from the bronchial asthma, who were sent to the allergy department to verify the diagnosis. Bronchial asthma supervision evaluation was assisted by the act test. The research has showed that over a half (56% of teenagers, suffering from mild bronchial asthma, mention its un control course, do not receive any adequate pharmacotherapy and are consequently a risk group in terms of the bronchial asthma exacerbation. Act test results correlate with the functional indices (fev1, as well as with the degree of the bronchial hyperresponsiveness, which is one of the markers of an allergic inflammation in the lower respiratory passages.Key words: bronchial asthma supervision, act test, teenagers.

Updating radon daughter bronchial dosimetry

International Nuclear Information System (INIS)

Harley, N.H.; Cohen, B.S.

1990-01-01

It is of value to update radon daughter bronchial dosimetry as new information becomes available. Measurements have now been performed using hollow casts of the human bronchial tree with a larynx to determine convective or turbulent deposition in the upper airways. These measurements allow a more realistic calculation of bronchial deposition by diffusion. Particle diameters of 0.15 and 0.2 μm were used which correspond to the activity median diameters for radon daughters in both environmental and mining atmospheres. The total model incorporates Yeh/Schum bronchial morphometry, deposition of unattached and attached radon daughters, build up and decay of the daughters and mucociliary clearance. The alpha dose to target cells in the bronchial epithelium is calculated for the updated model and compared with previous calculations of bronchial dose

Medical records, radiographs, and bronchial cytologic abnormalities of 65 cats with bronchial disease were reviewed. Bronchial disease was defined as abnormality of the lower airways to the exclusion of disease originating or mainly involving the alveoli, interstitium, vasculature, or pleura. Cats with bronchial disease were more likely to be female and older. Siamese cats were over represented and had more chronic disease. In order of frequency, the following clinical signs were reported: coughing, dyspnea, occasional sneezing, wheezing, and vomiting. Radiography revealed prominent bronchial markings, with some cats having collapse of the middle lobe of the right lung (n = 7), overinflation of the lungs (n = 9), or aerophagia (n = 13). Of 65 bronchial washes, 58 were considered exudative, with the predominant cell type being eosinophil in 24%, neutrophil in 33%, macrophage in 22%, and mixed population of cells in 21%. Cultures for bacteria were considered positive in 24% of the cats. Circulating eosinophilia was not helpful in predicting the predominant cell type in bronchial cytologic exudates. Hyperproteinemia without dehydration was present in a third of the cats, indicating an immunologic response. Half the cats had resolution of clinical signs, whereas half the cats required continuing medication with bronchodilators, antimicrobial agents, or corticosteroids

Objective Oronasal fistula is an important complication of cleft palate repair that is frequently used to evaluate surgical quality, yet reliability of fistula classification has never been examined. The objective of this study was to determine the reliability of oronasal fistula classification both within individual surgeons and between multiple surgeons. Design Using intraoral photographs of children with repaired cleft palate, surgeons rated the location of palatal fistulae using the Pittsburgh Fistula Classification System. Intrarater and interrater reliability scores were calculated for each region of the palate. Participants Eight cleft surgeons rated photographs obtained from 29 children. Results Within individual surgeons reliability for each region of the Pittsburgh classification ranged from moderate to almost perfect (κ = .60-.96). By contrast, reliability between surgeons was lower, ranging from fair to substantial (κ = .23-.70). Between-surgeon reliability was lowest for the junction of the soft and hard palates (κ = .23). Within-surgeon and between-surgeon reliability were almost perfect for the more general classification of fistula in the secondary palate (κ = .95 and κ = .83, respectively). Conclusions This is the first reliability study of fistula classification. We show that the Pittsburgh Fistula Classification System is reliable when used by an individual surgeon, but less reliable when used among multiple surgeons. Comparisons of fistula occurrence among surgeons may be subject to less bias if they use the more general classification of "presence or absence of fistula of the secondary palate" rather than the Pittsburgh Fistula Classification System.

Surgical Management of Enterocutaneous Fistula

International Nuclear Information System (INIS)

Lee, Suk Hwan

Enterocutaneous (EC) fistula is an abnormal connection between the gastrointestinal (GI) tract and skin. The majority of EC fistulas result from surgery. About one third of fistulas close spontaneously with medical treatment and radiologic interventions. Surgical treatment should be reserved for use after sufficient time has passed from the previous laparotomy to allow lysis of the fibrous adhesion using full nutritional and medical treatment and until a complete understanding of the anatomy of the fistula has been achieved. The successful management of GI fistula requires a multi-disciplinary team approach including a gastroenterologist, interventional radiologist, enterostomal therapist, dietician, social worker and surgeons. With this coordinated approach, EC fistula can be controlled with acceptable morbidity and mortality.

Vesicovaginal fistula in Uganda.

Kitovu Hospital in Masaka, Uganda, is a leading obstetric fistula repair centre in the country with the highest rates of fistula in the world. In this retrospective case review, the regional incidence and causative factors were studied in patients with vesicovaginal fistula (VVF) who were admitted at Kitovu Hospital. Fistula history included severity (ICIQ score), causes and outcomes of VVF were measured. Women suffered with symptoms of VVF for an average of 4.97 years with an average ICIQ severity score of 7.21. Patients travelled an average distance of 153 km and the majority travelled by public transport. Rates of prolonged labour were high. 69% of fistula-causing delivery resulted in stillbirth and 12% resulted in early neonatal death. Following surgery, 94% of patients were dry on discharge. Impact statement What is already known on this subject? Vesicovaginal fistula (VVF) is a severe, life-changing injury. Although largely eradicated from the Western world thanks to modern obstetric practice, VVF is still highly prevalent in developing countries where factors such as young childbearing age and poor access to emergency obstetric care increase the incidence (Wall et al. 2005 ). At the current rate of fistula repair, it is estimated that it would take 400 years to treat those already suffering with fistula, providing that no new cases emerged (Browning and Patel 2004 ). What do the results of this study add? The Ugandan women in this study reiterate tales of foetal loss, social isolation and epic journeys in search of fistula repair, as previously described in the literature. The study offers some hope for prompt help-seeking during labour and after fistulas are developed. It demonstrates the success of fistula repairs at Kitovu Hospital but highlights the paucity of service provision across Uganda. What are the implications of these findings for clinical practice and/or further research? Further epidemiological research is required to quantify the true

Bronchial dosimeter for radon progeny

Traditionally, assessments of the bronchial dose from radon progeny were carried out by measuring the unattached fraction (f{sub p}) of potential alpha energy concentration (PAEC), the total PAEC, activity median diameters (AMDs) and equilibrium factor, and then using dosimetric lung models. A breakthrough was proposed by Hopke et al. (1990) to use multiple metal wire screens to mimic the deposition properties of radon progeny in the nasal (N) and tracheobronchial (T-B) regions directly. In particular, they were successful in using four layers of 400-mesh wire screens with a face velocity of 12 cm s{sup -1} for the simulation of radon progeny deposition in the T-B region. Oberstedt and Vanmarcke (1995) carried out precise calibrations for the system, and named the system as the 'bronchial dosimeter'. Based on these, Yu and Guan (1998) proposed a portable bronchial dosimeter similar to a normal measurement system for radon progeny or PAEC and consisted of only a single sampler and employed only one 400-mesh wire screen and one filter. However, all these 'bronchial dosimeters' in fact only determined the fraction of potential alpha energy from radon progeny deposited in the T-B region, which required certain assumptions and calculations to further give the final bronchial dose. In the present work, a true 'bronchial dosimeter' was designed, which consisted of three 400-mesh wire screens and a filter. With a face velocity of 11 cm s{sup -1}, the deposition pattern on the wire screens was found to satisfactorily match the variation of the dose conversion factor (in the unit of mSv/WLM) with the size of radon progeny from 1 to 1000 nm. In this way, this bronchial dosimeter directly gave the bronchial dose from the alpha counts recorded on the wire-screens and the filter paper. With the development of this bronchial dosimeter, the present practice of 'dose estimation' from large-scale radon surveys can be replaced by large

To review the surgical anatomy and histopathology of second branchial cleft fistulae. Retrospective study of patients treated for second branchial cleft fistulae at a tertiary care pediatric hospital. The senior author noted anatomic and histologic features of second branchial cleft fistulae, not previously described. Tertiary care children's hospital. Retrospective examination of 28 patients was conducted who were operated upon for second branchial cleft fistula. Data collected included age at surgery, initial presentation, imaging characteristics prior to surgery, laterality of the fistula tract, pathology results and follow-up data. Twenty-eight patients met the criteria for inclusion. Three patients (11%) had bilateral fistulae. 11 (39%) were male and 17 (61%) were female. 23 (74.2%) tracts were lined with ciliated columnar epithelium, 3 (9.7%) had cuboidal epithelium, and 5 (16.7%) had squamous epithelium. Nineteen (61.3%) tracts contained salivary tissue. Of the unilateral fistula tracts, 25 (100%) were on the right side. Of the 3 patients with bilateral lesions, 2 (66%) had associated branchio-oto-renal syndrome (BORS). Second branchial cleft fistulae are rare. They are usually right-sided. If bilateral fistulae are present, one should consider an underlying genetic disorder. The histology of the fistulae mostly demonstrates ciliated columnar epithelium with the majority of specimens showing salivary tissue. There is a clear association with the internal jugular vein (IJV). Dissection should continue until superior to the hyoid bone, ensuring near complete surgical dissection and less risk of recurrence.

The two main sources of blood supply to the lungs and their supporting structures are the pulmonary and bronchial arteries. The bronchial arteries account for 1% of the cardiac output but can be recruited to provide additional systemic circulation to the lungs in various acquired and congenital thoracic disorders. An understanding of bronchial artery anatomy and function is important in the identification of bronchial artery dilatation and anomalies and the formulation of an appropriate differential diagnosis. Visualization of dilated bronchial arteries at imaging should alert the radiologist to obstructive disorders that affect the pulmonary circulation and prompt the exclusion of diseases that produce or are associated with pulmonary artery obstruction, including chronic infectious and/or inflammatory processes, chronic thromboembolic disease, and congenital anomalies of the thorax (eg, proximal interruption of the pulmonary artery). Conotruncal abnormalities, such as pulmonary atresia with ventricular septal defect, are associated with systemic pulmonary supply provided by aortic branches known as major aortopulmonary collaterals, which originate in the region of the bronchial arteries. Bronchial artery malformation is a rare left-to-right or left-to-left shunt characterized by an anomalous connection between a bronchial artery and a pulmonary artery or a pulmonary vein, respectively. Bronchial artery interventions can be used successfully in the treatment of hemoptysis, with a low risk of adverse events. Multidetector computed tomography helps provide a vascular road map for the interventional radiologist before bronchial artery embolization. RSNA, 2015

Retrograde Instillation of Methylene Blue in the Difficult Diagnosis of BPF

Directory of Open Access Journals (Sweden)

F. Ravenna

2012-01-01

Full Text Available We report two cases in which we were able to diagnose bronchopleural fistula through retrograde methylene blue instillation during bronchoscopy. In the first case, methylene blue was injected through an abdominal drain, followed by air instillation and detected in the left bronchial tree, demonstrating the presence of a fistula in the lingula’s bronchus. In the second case, methylene blue was injected into a pleural drain, through a breach on a surgical suture and detected in the right bronchial tree, demonstrating the presence of a fistula in the right inferior bronchus. The retrograde instillation of methylene blue, through a drain in the abdomen or the thoracic wall, is a safe, cheap, and practical method that allows the bronchoscopist to identify the presence of a fistula and, more importantly, to identify the exact point on the bronchial tree where a fistula is located. This provides the possibility of sealing the fistula with a variety of devices. It is our opinion that this procedure should be considered a primary method of diagnosis when a bronchopleural fistula is suspected and a drain on the thoracic or abdominal wall is positioned such that effusions are able to drain.

Until now, it is unknown whether and to what extent arteriosclerotic disease affects the bronchial arteries. We conducted this pilot study to estimate the prevalence of arteriosclerosis of the bronchial arteries, to correlate it with certain clinicolaboratory arteriosclerotic parameters or any coexistent coronary artery disease (CAD) and to validate the clinical significance. Bronchial arteries 10-15 mm long were obtained from 40 patients with a mean age of 62.3 years who underwent major thoracic procedures. Their medical history and detailed clinical and laboratory arteriosclerotic risk factors were documented. The mean diameter of bronchial artery specimens was 0.97 mm. Histology revealed medial calcific sclerosis only in 1 patient (2.5%) without simultaneous, established atherosclerotic lesions or narrowing of the lumen. Furthermore, the vessel diameter was significantly correlated not only with the advanced stage of the disease (p = 0.031), but also with the proximal occlusion of the bronchial tree (p = 0.042). We noted a marginally not significant correlation between arteriosclerosis and metabolic syndrome (p = 0.075), independent from a history of CAD (p = 0.84). Bronchial arteries exhibit only medial calcific sclerosis. CAD and chronic obstructive pulmonary disease do not seem to affect them in terms of atherosclerotic alteration findings or vessel diameter changes. The bronchial resistance to arteriosclerosis might support the mediastinal status quo through their anastomoses, contributing to all its structures, and might be indirect evidence of a different physiological function of the bronchial endothelium, which needs to be further investigated.

Out of 136 patients with radiation-induced intestinal complications, 45 had fistulae. Twenty-eight patients had rectovaginal fistulae while the remainder had a total of 13 different types of fistulae. Thirty-seven patients were treated operatively and eight were treated conservatively. Thirty-three patients were submitted to operation for rectal fistulae. Of these, 28 were treated by defunctioning colostomy, three were treated by Hartmann's method and resection and primary anastomosis was carried out in two patients. In the course of the period of observation, 35% of the patients developed new radiation damage. The frequency in the basic material without fistulae was 21% (0.05< p<0.10).

Full Text Available Background: Coverage of the bronchial stumps (BSs with adjacent tissues can improve healing and reduce bronchial complications in complex thoracic surgery. There is no evidence for the application of human amnion allograft for prevention of air leak from the BS. The comparison of the amniotic membrane (AM and pleural patch for BS healing after lobectomy in dogs was our aim in this study. Materials and Methods: A total of eight males and females 12-24-month-old dogs between 17 and 22 kg body-weight were used in this study in 2010, Isfahan University of Medical Sciences. Animals were separated into two groups: group A (n = 4; amniotic membrane and group P (n = 4; pleural patch according to the BS closure technique performed. After lobectomy of the right middle lobe, the BS was closed, while a small bronchopleural fistula (BPF was created by inserting a catheter via edges of closed stump. Then, it was covered with a piece of AM3 × 3 cm in group A and with a pedicle graft of pleura in group P. Rethoracotomy was performed after 15 days of observation, and the BS was removed for histological examination. Histological healing was classified as complete or incomplete healing. Neoangiogenesis was measured by Von Willebrand expression using immunohistochemistry (IHC. Data were analyzed by SPSS version 15 using Fisher′s exact test, Mann-Whitney test, and T tests. Results: BPF complications were not seen during observation period. There was no significant difference in histological healing between two groups. Similarly, no significant difference was observed between the groups in terms of neoangiogenesis based on IHC examination (P value = 0.69. Conclusion: Human amnion allograft could be as effective as pleural patch for BS wrapping following pulmonary resections.

In patients with bronchial tumors, we frequently consider endoscopic treatment as the first treatment of choice. All computed tomography (CT) must satisfy several conditions necessary to analyze images by Synapse Vincent. To select safer and more precise approaches for patients with bronchial tumors, we determined the indications and efficacy of virtual navigation intervention for the treatment of bronchial tumors. We examined the efficacy of virtual navigation bronchial intervention for the treatment of bronchial tumors located at a variety of sites in the tracheobronchial tree using a high-speed 3-dimensional (3D) image analysis system, Synapse Vincent. Constructed images can be utilized to decide on the simulation and interventional strategy as well as for navigation during interventional manipulation in two cases. Synapse Vincent was used to determine the optimal planning of virtual navigation bronchial intervention. Moreover, this system can detect tumor location and alsodepict surrounding tissues, quickly, accurately, and safely. The feasibility and safety of Synapse Vincent in performing useful preoperative simulation and navigation of surgical procedures can lead to safer, more precise, and less invasion for the patient, and makes it easy to construct an image, depending on the purpose, in 5-10 minutes using Synapse Vincent. Moreover, if the lesion is in the parenchyma or sub-bronchial lumen, it helps to perform simulation with virtual skeletal subtraction to estimate potential lesion movement. By using virtual navigation system for simulation, bronchial intervention was performed with no complications safely and precisely. Preoperative simulation using virtual navigation bronchial intervention reduces the surgeon's stress levels, particularly when highly skilled techniques are needed to operate on lesions. This task, including both preoperative simulation and intraoperative navigation, leads to greater safety and precision. These technological instruments

Video-Assisted Anal Fistula Treatment: Pros and Cons of This Minimally Invasive Method for Treatment of Perianal Fistulas

Full Text Available Purpose. The purpose of this paper is to present results of a single-center, nonrandomized, prospective study of the video-assisted anal fistula treatment (VAAFT. Methods. 68 consecutive patients with perianal fistulas were operated on using the VAAFT technique. 30 of the patients had simple fistulas, and 38 had complex fistulas. The mean follow-up time was 31 months. Results. The overall healing rate was 54.41% (37 of the 68 patients healed with no recurrence during the follow-up period. The results varied depending on the type of fistula. The success rate for the group with simple fistulas was 73.3%, whereas it was only 39.47% for the group with complex fistulas. Female patients achieved higher healing rates for both simple (81.82% versus 68.42% and complex fistulas (77.78% versus 27.59%. There were no major complications. Conclusions. The results of VAAFT vary greatly depending on the type of fistula. The procedure has some drawbacks due to the rigid construction of the fistuloscope and the diameter of the shaft. The electrocautery of the fistula tract from the inside can be insufficient to close wide tracts. However, low risk of complications permits repetition of the treatment until success is achieved. Careful selection of patients is advised.

Anal fistula is a common disease. It is also quite difficult to be solved without recurrence or damage to the anal sphincter. Several techniques have been described for the management of anal fistula, but there is no final conclusion of their application in the treatment. This article summarizes the history of anal fistula management, the current techniques available, and describes new technologies. Internet online searches were performed from the CNKI and Wanfang databases to identify articles about anal fistula management including seton, fistulotomy, fistulectomy, LIFT operation, biomaterial treatment and new technology application. Every fistula surgery technique has its own place, so it is reasonable to give comprehensive individualized treatment to different patients, which may lead to reduced recurrence and avoidance of damage to the anal sphincter. New technologies provide promising alternatives to traditional methods of management. Surgeons still need to focus on the invention and improvement of the minimally invasive techniques. Besides, a new therapeutic idea is worth to explore that the focus of surgical treatment should be transferred to prevention of the formation of anal fistula after perianal abscess.

Martius procedure revisited for urethrovaginal fistula

N P Rangnekar

2000-01-01

Full Text Available Background: Urethrovaginal fistula is a dreadful com-plication of obstetric trauma due to prolonged labour or obstetric intervention commonly seen in developing coun-tries. Due to prolonged ischaemic changes, the fistula is resistant to healing. The strategic location of the fistula leads to postoperative impairment of continence mecha-nism. Anatomical repair was previously the commonest mode of surgical management, but was associated with a miserable cumulative cure rate ranging from 16-60%. Hence we tried to study the efficacy of Martius procedure in the management of urethrovaginal fistula. Material and Methods: We studied the outcome of 12 urethrovaginal fistulae, all caused by obstetric trauma, treated surgically with Martius procedure in 8 and with anatomical repair in 4, retrospectively. 9 patients had re-current fistulae while I patient had multiple fistulae. Pa-tients were followed up for the period ranging from 6 months to 4′/2 years for fistula healing, continence and postoperative complications like dvspareunia. Results: Cumulative cure rate ofMartius procedure was 87.5% with no postoperative stress incontinence, while fistula healing rate of anatomical repair was only 25% (I patient out of 4 which was also complicated by Intrin-sic Sphincter Deficiency (ISD. In case of recurrent fistu-lae the success rate of anatomical repair was 0% compared to 83.33% with Martius procedure. Conclusions: Martius procedure has shown much bet-ter overall cure rate compared to anatomical repair be-cause - a it provides better reinforcement to urethral suture line, b it provides better blood supply and lymph drainage to the ischaemic fistulous area, c provides sur-face for epithelialization and, d helps to maintain conti-nence. Hence we recommend Martius procedure as a surgical modality for the treatment of urethrovaginal fis-tula.

Vesicouterine fistulae as an obstetrical complication have been reported only in women with a history of cesarean. We present a patient with no such history who developed a vesicouterine fistula after vaginal delivery. A 43-year-old gravida 5 at term with no history of cesarean presented in the latent phase of labor. Gross hematuria was noted intrapartum, and a foley catheter was placed. A cystogram showed an extraperitoneal bladder perforation. The patient had urinary incontinence despite Foley catheter drainage. The diagnosis of vesicouterine fistula was made by cystoscopy and fistulogram. The patient had a successful repair at 3 months. This is a rare case of a vesicouterine fistula developing during a pregnancy with no previous cesarean. Accurate diagnosis is essential because surgical repair has an excellent outcome.

Full Text Available Broncho-pleural fistula (BPF and esophago-pleural fistula (EPF after pulmonary resection are challenging to manage. BPF is controlled by irrigation and sterilization, but such therapy is not sufficient to promote closure of EPF, which usually requires surgical management. However, it is generally difficult to select an appropriate surgical method for closure of BPF and EPF. Here, we report a case of concomitant BPF and EPF after left completion pneumonectomy, in which both fistulas were closed through a right thoracotomy.

Fistula is considered to be any abnormal passage which connects two epithelial surfaces. Parks’ fistulae classification demonstrates the biggest practical significance and divides fistulae into: intersphincteric, transsphincteric, suprasphincteric and extrasphincteric. Etiology of perianal fistulae is most commonly linked with the inflammation of anal glands in Crohn’s disease, tuberculosis, pelvic infections, pelvic malignant tumours, and with the radiotherapy. Diagnostic method options are: RTG fistulography, CT fistulography and magnetic resonance imaging (MRI) of pelvic organs. We have included 24 patients with perirectal fistulae in the prospective study. X-rays fistulography, CT fistulography, and then MRI of the pelvic cavity have been performed on all patients. Accuracy of each procedure in regards to the patients and the etiologic cause have been statistically determined. 29.16% of transphincteric fistulae have been found, followed by 25% of intersphincteric, 25% of recto-vaginal, 12.5% of extrasphincteric, and 8.33% of suprasphincteric. Abscess collections have been found in 16.6% patients. The most frequent etiologic cause of perianal fistulae was Crohn’s disease in 37.5%, where the accuracy of classification of MRI was 100%, CT was 11% and X-rays 0%. Ulcerous colitis was the second cause, with 20.9% where the accuracy of MRI was 100%, while CT was 80% and X-rays was 0%. All other etiologic causes of fistulae were found in 41.6% patients. MRI is a reliable diagnostic modality in the classification of perirectal fistulae and can be an excellent diagnostic guide for successful surgical interventions with the aim to reduce the number of recurrences. Its advantage is that fistulae and abscess are visible without the need to apply any contrast medium

Traumatic subarachnoid-pleural fistulas are rare. The authors found nine cases reported since 1959. Seven have been secondary to trauma and two following thoracotomy. One patient's death is thought to be directly related to the fistula. The diagnosis should be suspected in patients with a pleural effusion and associated vertebral trauma. The diagnosis can usually be confirmed with contrast or radioisotopic myelography. Successful closure of the fistula will usually occur spontaneously with closed tube drainage and antibiotics; occasionally, thoracotomy is necessary to close the rent in the dura

Modern LDR brachytherapy has drastically reduced rectal toxicity and decreased the occurrence of rectourethral fistulas to <0.5% of patients. Therefore, symptoms of late-onset sequelae are often ignored initially. These fistulas cause severe patient morbidity and require interdisciplinary treatment. We report on the occurrence and management of a rectourethral fistula which occurred 4 years after (125)I seed implantation. Copyright 2009 S. Karger AG, Basel.

Rios, Hugo Palma; Goulart, André; Rolanda, Carla; Leão, Pedro

2017-09-01

Video-assisted anal fistula treatment (VAAFT) is a novel minimally invasive and sphincter-saving technique to treat complex anal fistulas described by Meinero in 2006. An enterocutaneous fistula is an abnormal communication between the bowel and the skin. Most cases are secondary to surgical complications, and managing this condition is a true challenge for surgeons. Postoperative fistulas account for 75-85% of all enterocutaneous fistulas. The aim of paper was to devise a minimally invasive technique to treat enterocutaneous fistulas. We used the same principles of VAAFT applied to other conditions, combining endoluminal vision of the tract with colonoscopy to identify the internal opening. We present a case of a 78-year-old woman who was subjected to a total colectomy for cecum and sigmoid synchronous adenocarcinoma. The postoperative course was complicated with an enterocutaneous fistula, treated with conservative measures, which recurred during follow-up. We performed video-assisted fistula treatment using a fistuloscope combined with a colonoscope. Once we identified the fistula tract, we performed cleansing and destruction of the tract, applied synthetic cyanoacrylate and sealed the internal opening with clips through an endoluminal approach. The patient was discharged 5 days later without complications. Two months later the wound was completely healed without evidence of recurrence. This procedure represents an alternative treatment for enterocutaneous fistula using a minimally invasive technique, especially in selected patients not able to undergo major surgery.

[Thoracic surgery for patients with bronchial asthma].

Science.gov (United States)

Iyoda, A; Satoh, Y

2012-07-01

Thoracic surgery poses a risk for complications in the respiratory system. In particular, for patients with bronchial asthma, we need to care for perioperative complications because it is well known that these patients frequently have respiratory complications after surgery, and they may have bronchial spasms during surgery. If we can get good control of their bronchial asthma, we can usually perform surgery for these patients without limitations. For safe postoperative care, it is desirable that these patients have stable asthma conditions that are well-controlled before surgery, as thoracic surgery requires intrabronchial intubation for anesthesia and sometimes bronchial resection. These stimulations to the bronchus do not provide for good conditions because of the risk of bronchial spasm. Therefore, we should use the same agents that are used to control bronchial asthma if it is already well controlled. If it is not, we have to administer a β₂ stimulator, aminophylline, or steroidal agents for good control. Isoflurane or sevoflurane are effective for the safe control of anesthesia during surgery, and we should use a β₂ stimulator, with or without inhalation, or steroidal agents after surgery. It is important to understand that we can perform thoracic surgery for asthma patients if we can provide perioperative control of bronchial asthma, although these patients still have severe risks.

MRI is routinely used in the investigation of colovesical fistulae at our institute. Several papers have alluded to its usefulness in achieving the diagnosis; however, there is a paucity of literature on its imaging findings. Our objective was to quantify the MRI characteristics of these fistulae. We selected all cases over a 4-year period with a final clinical diagnosis of colovesical fistula which had been investigated with MRI. The MRI scans were reviewed in a consensus fashion by two consultant uroradiologists. Their MRI features were quantified. There were 40 cases of colovesical fistulae. On MRI, the fistula morphology consistently fell into three patterns. The most common pattern (71%) demonstrated an intervening abscess between the bowel wall and bladder wall. The second pattern (15%) had a visible track between the affected bowel and bladder. The third pattern (13%) was a complete loss of fat plane between the affected bladder and bowel wall. MRI correctly determined the underlying aetiology in 63% of cases. MRI is a useful imaging modality in the diagnosis of colovesical fistulae. The fistulae appear to have three characteristic morphological patterns that may aid future diagnoses of colovesical fistulae. To the authors' knowledge, this is the first publication of the MRI findings in colovesical fistulae.

Enterovesical Fistulae: Aetiology, Imaging, and Management

Full Text Available Background and Study Objectives. Enterovesical fistula (EVF is a devastating complication of a variety of inflammatory and neoplastic diseases. Radiological imaging plays a vital role in the diagnosis of EVF and is indispensable to gastroenterologists and surgeons for choosing the correct therapeutic option. This paper provides an overview of the diagnosis of enterovesical fistulae. The treatment of fistulae is also briefly discussed. Material and Methods. We performed a literature review by searching the Medline database for articles published from its inception until September 2013 based on clinical relevance. Electronic searches were limited to the keywords: “enterovesical fistula,” “colovesical fistula” (CVF, “pelvic fistula”, and “urinary fistula”. Results. EVF is a rare pathology. Diverticulitis is the commonest aetiology. Over two-thirds of affected patients describe pathognomonic features of pneumaturia, fecaluria, and recurrent urinary tract infections. Computed tomography is the modality of choice for the diagnosis of enterovesical fistulae as not only does it detect a fistula, but it also provides information about the surrounding anatomical structures. Conclusions. In the vast majority of cases, this condition is diagnosed because of unremitting urinary symptoms after gastroenterologist follow-up procedures for a diverticulitis or bowel inflammatory disease. Computed tomography is the most sensitive test for enterovesical fistula.

Labyrinthine fistula is one of the most common complications associated with cholesteatoma. It represents an erosive loss of the endochondral bone overlying the labyrinth. Reasons for cholesteatoma-induced labyrinthine fistula are still poorly understood. Evaluate patients with cholesteatoma, in order to identify possible risk factors or clinical findings associated with labyrinthine fistula. Secondary objectives were to determine the prevalence of labyrinthine fistula in the study cohort, to analyze the role of computed tomography and to describe the hearing results after surgery. This retrospective cohort study included patients with an acquired middle ear cholesteatoma in at least one ear with no prior surgery, who underwent audiometry and tomographic examination of the ears or surgery at our institution. Hearing results after surgery were analyzed according to the labyrinthine fistula classification and the employed technique. We analyzed a total of 333 patients, of which 9 (2.7%) had labyrinthine fistula in the lateral semicircular canal. In 8 patients, the fistula was first identified on image studies and confirmed at surgery. In patients with posterior epitympanic and two-route cholesteatomas, the prevalence was 5.0%; and in cases with remaining cholesteatoma growth patterns, the prevalence was 0.6% (p=0.16). In addition, the prevalence ratio for labyrinthine fistula between patients with and without vertigo was 2.1. Of patients without sensorineural hearing loss before surgery, 80.0% remained with the same bone conduction thresholds, whereas 20.0% progressed to profound hearing loss. Of patients with sensorineural hearing loss before surgery, 33.33% remained with the same hearing impairment, whereas 33.33% showed improvement of the bone conduction thresholds' Pure Tone Average. Labyrinthine fistula must be ruled out prior to ear surgery, particularly in cases of posterior epitympanic or two-route cholesteatoma. Computed tomography is a good diagnostic

Physiologic assessment of coronary artery fistula

Coronary artery fistula is an uncommon clinical entity. The most common coronary artery fistula is from the right coronary artery to the right side of the heart, and it is less frequent to the pulmonary artery. The effect of a coronary artery fistula may be physiologically significant because of the steal phenomenon resulting in coronary ischemia. Based on published reports, it is recommended that patients with congenital coronary artery fistulas be considered candidates for elective surgical correction to prevent complications including development of congestive heart failure, angina, subacute bacterial endocarditis, myocardial infarction, and coronary aneurysm formation with rupture or embolization. A patient is presented in whom treadmill-exercise thallium imaging was effective in determining the degree of coronary steal from a coronary artery fistula, leading to successful corrective surgery.

Purpose: To evaluate the role of MR imaging in the localisation of cerebrospinal fluid (CSF) fistulae. Material and Methods: A total of 36 consecutive unselected patients with either clincally proven CSF leakage (n=26) or suspected CSF fistula (n=10) were prospectively evaluated by MR. All MR examinations included fast spin-echo T2-weighted images in the 3 orthogonal planes. Thin-section CT was performed following equivocal or negative MR examination. MR and CT findings were correlated with surgical results in 33 patients. Results: CSF fistula was visualised as a dural-bone defect with hyperintense fluid signal continuous with that in the basal cisterns on T2-weighted images. MR was positive in 26 cases, in 24 of which the fistula was confirmed surgically. In 2 patients the CSF leakage was directly demonstrated on MR. MR sensitivity of 80% compared favourably with the reported 46-81% of CT cisternography (CTC). No significant difference in MR sensitivity in detecting CSF fistula was found between active and inactive leaks. (orig.)

Management of intestinal fistulae in open abdominal wounds remains a significant clinical challenge for those caring for patients surviving damage control abdominal operations. Breaking the cycle of tissue inflammation, infection, and sepsis, resulting from leakage of enteric contents, should be a major goal in the approach to these complex patients. We describe a technique utilizing vacuum assisted closure (VAC) which achieves control of enteric flow from fistulae in open abdominal wounds. The fistula-VAC is fashioned from standard sponge supplies, negative pressure pumps, and ostomy appliances. The fistula-VAC was changed every three days prior to split thickness skin grafting, and every five days following grafting. Five patients underwent application of the fistula-VAC. All patients had complete diversion of enteric contents. This enteric diversion allowed for successful skin grafting in all patients. Application of the fistula-VAC should be considered a useful option in treating patients with intestinal fistulae in open abdominal wounds.

Obstetric fistula is treatable by surgery, although access is usually limited, particularly in the context of conflict. This study examines the profile of women attending fistula repair surgery in three hospitals in Somalia. A cross-sectional study was conducted in Somalia from August to September 2016. Structured questionnaires were administered to 81 women who registered for fistula repair surgery in the Garowe, Daynile, and Kismayo General Hospitals in Somalia. Findings revealed that 70.4% of the study participants reported obstetric labor as the cause of their fistula, and 29.6% reported iatrogenic causes. Regarding the waiting time for the repair surgery, 45% waited for the surgery for over one year, while the rest received the surgery within a year. The study suggests that training for fistula surgery has to be provided for healthcare professionals in Somalia, fistula centers should be established, and access to these facilities has to be guaranteed for all patients who need these services.

We studied the effects of aerosolized as well as intravenous infusion of acetylcholine on bronchial blood flow in six anesthetized sheep. Intravenous infusion of acetylcholine, at a dose of 2 microg/kg, increased bronchial blood flow from 45 +/- 15 (SE) to 74 +/- 30 ml/min, and vascular conductance increased by 76 +/- 22%. In contrast, aerosolized acetylcholine at doses of 2 and 20 microg/kg decreased bronchial vascular conductance by approximately 10%. At an aerosolized dose of 200 microg/kg, the bronchial vascular conductance increased by approximately 15%, and there was no further increase in conductance when the aerosolized dose was increased to 2,000 microg/kg. Pretreatment of animals with a nitric oxide synthase inhibitor, Nomega-nitro-L-arginine methyl ester hydrochloride, partially blocked the vasodilatory effects of intravenous acetylcholine and completely blocked the vasodilatory effects of high-dose aerosolized acetylcholine. These data suggest that aerosolized acetylcholine does not readily penetrate the vascular wall of bronchial circulatory system and, therefore, has minimal vasodilatory effects on the bronchial vasculature.

A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

The purpose of this case report was to describe the surgical correction of a cholecystocutaneous fistula in a dog. A 6 yr old Vizsla presented with a 2 mo history of a chronic draining wound on the right ventral thorax. Diagnostics revealed numerous fistulous tracts opening at a single site on the right ventrolateral chest wall, extending caudodorsally through the chest wall and diaphragm to the region of the right medial liver lobe. Exploratory laparotomy revealed the apex of the gallbladder adhered to the diaphragm with a tract of fibrous tissue extending along the diaphragm laterally to the right thoracic wall. Cholecystectomy was performed. The fistulous tract was incised to expose the lumen of the fistula, and the fistula was omentalized. Twenty-eight months after surgery, the dog had had no recurrence of the fistulous tract. Exploratory laparotomy allowed excellent visualization of the intra-abdominal path of the fistula and facilitated the ease of resection of the source. Cholecystectomy resulted in rapid and complete resolution of the fistula without the need for excision of the fistula. Although rare, gallbladder disease should be a differential for chronic fistulous tracts.

Recent developments regarding periostin in bronchial asthma

Full Text Available Although it is currently recognized that bronchial asthma is not a single disease but a syndrome, we have not yet made use of our new understanding of this heterogeneity as we treat asthma patients. To increase the efficacy of anti-asthma drugs and to decrease costs, it is important to stratify asthma patients into subgroups and to develop therapeutic strategies for each subgroup. Periostin has recently emerged as a biomarker for bronchial asthma, unique in that it is useful not in diagnosis but in categorizing asthma patients. We first found that periostin is a novel component of subepithelial fibrosis in bronchial asthma downstream of IL-13 signals. Thereafter, it was shown that periostin can be a surrogate biomarker of type 2 immune responses, the basis of the notion that a detection system of serum periostin is potentially a companion diagnostic for type 2 antagonists. Furthermore, we have recently shown that serum periostin can predict resistance or hyporesponsiveness to inhaled corticosteroids, based on its contribution to tissue remodeling or fibrosis in bronchial asthma. Thus, serum periostin has two characteristics as a biomarker for bronchial asthma: it is both a surrogate biomarker of type 2 immune responses and a biomarker reflecting tissue remodeling or fibrosis. We can take advantage of these characteristics to develop stratified medicine in bronchial asthma.

Arteriovenous fistulae of the cavernous sinus are rare and difficult to diagnose. They are classified into dural cavernous sinus fistulae or direct carotid-cavernous fistulae. Despite the similarity of symptoms between both types, a precise diagnosis is essential since the treatment is specific for each type of fistula. Imaging findings are remarkably similar in both dural cavernous sinus fistulae and carotid-cavernous fistulae, but it is possible to differentiate one type from the other. Amongst the available imaging methods (Doppler ultrasonography, computed tomography, magnetic resonance imaging and digital subtraction angiography), angiography is considered the gold standard for the diagnosis and classification of cavernous sinus arteriovenous fistulae. The present essay is aimed at didactically presenting the classification and imaging findings of cavernous sinus arteriovenous fistulae. (author)

Gastrobronchial fistulous communications are uncommon complications of disease processes with only 36 previously reported cases. Described as complication of a number of conditions, such as previous gastroesophageal surgery, subphrenic abscess, and gastric ulcers (Jha P, Deiraniya A, Keeling-Robert C, et al. Gastrobronchial fistula--a recent series. Interact Cardiovasc Thorac Sur 2003;2:6-8), we report a case of fistulization caused by ingestion of a foreign body. A patient with mental retardation, admitted for the treatment of osteomyelitis, presented during hospitalization symptoms of high fever, vomiting, and respiratory distress. Endoscopy showed the presence of a gastrobronchial fistula, which developed after ingestion of a toothbrush. The toothbrush was extracted endoscopically, and the fistula was subsequently closed by surgery. The patient recovered completely. We report the first case of a gastrobronchial fistula as a complication of foreign body ingestion.

To evaluate peculiarities of a clinical course and changes in bronchial mucosa in bronchial asthma (BA) patients with chronic obstructive pulmonary disease (COPD) in combination with hyperoxaluria (HOU); informative value of some laboratory and device findings including oxalates assay in bronchial lavage fluid for specification of the diagnosis, role of oxalates in development of obstructive syndrome and choice of optimal therapy. Oxalates were examined in daily urine, bronchoalveolar lavage fluid and exhaled air condensate of 104 patients with BA and COPD, 77 of which had HOU and an atypical course of bronchial obstruction syndrome. Conception of airways inflammation in patients with oxalate metabolism disturbances is proposed. It is shown that insoluble oxalates participate in pathogenesis of bronchial obstruction. Oxalate metabolism disturbances are an important factor in pathogenesis of airways inflammation and development of bronchial obstruction in predisposed patients. Therefore, administration of insoluble oxalates lowering therapy may effectively prevent formation and progression of obstructive pulmonary diseases in this group of patients.

We report cases of posterior cranial fossa arteriovenous fistula (AVF) with presenting with exophthalmos, chemosis and tinnitus in 26- and 66-year-old men. The final diagnoses was vertebral artery AVF and AVF of the marginal sinus, respectively. The dominant venous drainage was the cause of the unusual presentation: both drained from the jugular bulb or marginal sinus, via the inferior petrosal and cavernous sinuses and superior ophthalmic vein. We used endovascular techniques, with coils and liquid adhesives to occlude the fistulae, with resolution of the symptoms and signs. (orig.)

Objective: To evaluate the ability of CT angiography in identifying and demonstrating the origins and courses of bronchial arteries by using the three-dimensional reformation technique. Methods Four hundred and forty-three eases were examined with thin-section enhanced MSCT. Three-dimensional images of bronchial arteries were processed at the workstation. Spatial anatomical characters of the bronchial arteries using volume rendering(VR), muhiplanar reconstruction (MPR), and maxium intensity projection (MIP) were observed. Results: At least one bronchial artery was clearly displayed in VR in 359 eases. The right bronchial arteries mainly appeared to originate from the right intercostal artery (213/436, 48.85% ) and descending aorta (207/436, 47.48%), while the left bronchial arteries mainly from the descending aorta (363/371, 97.84%). The right bronchial arteries of the descending aorta were mainly arised from fight wall (95/207, 45.89%), and then the anterior wall (88/207, 42.51%), while the left bronchial arteries of the descending aorta mainly arised from anterior wall of the aorta (272/363, 74.93%). The common trunk originated from the descending aorta mainly positioned in the anterior wall (57/77, 74.03%). 49.31% (215/436) of the fight bronchial arteries were coursing across the posterior edge of the right main bronchi, 35.55% (155/436) coursing the inferior edge, while 60.11% (223/371) of left bronchial arteries coursing forward across the superior edger of the left main bronchi, the others coursing the inferior or the posterior edge. There were eleven bronchial artery distribution patterns, with the right and left ones predominating (192/359, 53.48%), and then two right and one left (63/359, 17.55%). Conclusion: The bronchial artery anatomy was complicated, and CT angiography could clearly visualize the features. (authors)

Peri-anal fistulae are a worldwide health problem that can affect any person anywhere. Surgical management of these fistulae is not free from risks. Recurrence and fecal incontinence are the most common complica-tions after surgery. The cumulative personal surgical experience in managing cases with anal fistulae is sig-nificantly considered as necessary for obtaining better results with minimal adverse effects after surgery. The purpose for conducting this survey is to facilitate better outcome after surgical interventions in idiopathic anal fistulae' cases.

Objective: To evaluate the radiological findings of bronchial mucoid impaction in 28 patients in order to improve diagnostic efficacy. Methods: Standard posteroanterior high voltage radiographs were performed in all 28 cases. Among them CT scans were taken in 14 cases, while 3 patients underwent HRCT examination at the same time. Twenty-two patients had a history of expectoration of mucous plugs; in one case with pulmonary atelectasis, a mucous plug was picked out through bronchoscopy. The other 5 cases experienced a lung operation, and a tumor and bronchial mucoid impaction were discovered. Results: Radiographs showed most mucoid impaction as thick, branching structures resembling branches of tree; others were in the shapes of spherical, small clubs, and cuttle fish. In one patient, pulmonary atelectasis was the only radiographic finding. Similarly on CT, most bronchial mucoid impaction were likened to tree branches; the rest presented as small clubs and bunches of grape. A prominent feature of bronchial mucoid impaction, either on plain radiograph or on CT, was that its axis pointed to the hilum, completely consistent with the branching and distribution of the bronchi, and accompanied by bronchiectasis. Conclusions: It is an optimal approach to exploit plain radiograph combined with CT to find out bronchial mucoid impaction. An awareness of its clinical and radiological features may improve better understanding and recognition of the disease

Milk Fistula: Diagnosis, Prevention, and Treatment.

Milk fistula is an uncommon condition which occurs when there is an abnormal connection that forms between the skin surface and the duct in the breast of a lactating woman, resulting in spontaneous and often constant drainage of milk from this path of least resistance. A milk fistula is usually a complication that results from a needle biopsy or surgical intervention in a lactating patient. Here, the authors present an unusual case of a spontaneous milk fistula which developed from an abscess in the breast of a lactating woman. The patient initially presented to the office with a large open wound on her breast, formed from skin breakdown, within which milk was pooling. She was treated with local wound care and cessation of breastfeeding, with appropriate healing of the wound and closure of the fistula with 6 weeks. Diagnosis, prevention, and treatment of milk fistula were reviewed. © 2015 Wiley Periodicals, Inc.

Vesicovaginal fistula is a preventable calamity, which has been an age-long menace in developing countries. To review the causes, complications, and outcome of Vesicovaginal fistula in Nigeria. Studies on Vesicovaginal fistula were searched on the internet. Information was obtained on PubMed(medline), WHO website, Bioline International, African Journal of Line, Google scholar, Yahoo, Medscape and e Medicine. Many Nigerian women are living with Vesicovaginal fistula. The annual obstetric fistula incidence is estimated at 2.11 per 1000 births. It is more prevalent in northern Nigeria that southern Nigeria. Obstetric fistula accounts for 84.1%-100% of the Vesicovaginal fistula and prolonged obstructed labour is consistently the most common cause (65.9%-96.5%) in all the series. Other common causes include caesarean section, advanced cervical cancer, uterine rupture, and Gishiri cut. The identified predisposing factors were early marriage and pregnancy, which were rampant in northern Nigeria, while unskilled birth attendance and late presentation to the health facilities was common nationwide. Among the significant contributory factors to high rate of unskilled birth attendance and were poverty, illiteracy, ignorance, restriction of women's movement, non-permission from husband and transportation. All but one Nigerian studies revealed that primiparous women were the most vulnerable group. Pregnancy outcome was dismal in most cases related to delivery with still birth rate of 87%-91.7%. Stigmatization, divorce and social exclusion were common complications. Overall fistula repair success rate was between 75% and 92% in a few centres that offer such services. Vesicovaginal fistula is prevalent in Nigeria and obstetric factors are mostly implicated. It is a public health issue of concern.

Hemodynamic Simulations in Dialysis Access Fistulae

Science.gov (United States)

McGah, Patrick; Leotta, Daniel; Beach, Kirk; Riley, James; Aliseda, Alberto

2010-11-01

Arteriovenous fistulae are created surgically to provide adequate access for dialysis in patients with End-Stage Renal Disease. It has long been hypothesized that the hemodynamic and mechanical forces (such as wall shear stress, wall stretch, or flow- induced wall vibrations) constitute the primary external influence on the remodeling process. Given that nearly 50% of fistulae fail after one year, understanding fistulae hemodynamics is an important step toward improving patency in the clinic. We perform numerical simulations of the flow in patient-specific models of AV fistulae reconstructed from 3D ultrasound scans with physiologically-realistic boundary conditions also obtained from Doppler ultrasound. Comparison of the flow features in different geometries and configurations e.g. end-to-side vs. side-to-side, with the in vivo longitudinal outcomes will allow us to hypothesize which flow conditions are conducive to fistulae success or failure. The flow inertia and pulsatility in the simulations (mean Re 700, max Re 2000, Wo 4) give rise to complex secondary flows and coherent vortices, further complicating the spatio- temporal variability of the wall pressure and shear stresses. Even in mature fistulae, the anastomotic regions are subjected to non-physiological shear stresses (>10.12pcPa) which may potentially lead to complications.

[External pancreatic fistulas management].

Stepan, E V; Ermolov, A S; Rogal', M L; Teterin, Yu S

The main principles of treatment of external postoperative pancreatic fistulas are viewed in the article. Pancreatic trauma was the reason of pancreatic fistula in 38.7% of the cases, operations because of acute pancreatitis - in 25.8%, and pancreatic pseudocyst drainage - in 35.5%. 93 patients recovered after the treatment. Complex conservative treatment of EPF allowed to close fistulas in 74.2% of the patients with normal patency of the main pancreatic duct (MPD). The usage of octreotide 600-900 mcg daily for at least 5 days to decrease pancreatic secretion was an important part of the conservative treatment. Endoscopic papillotomy was performed in patients with major duodenal papilla obstruction and interruption of transporting of pancreatic secretion to duodenum. Stent of the main pancreatic duct was indicated in patients with extended pancreatic duct stenosis to normalize transport of pancreatic secretion to duodenum. Surgical formation of anastomosis between distal part of the main pancreatic duct and gastro-intestinal tract was carried out when it was impossible to fulfill endoscopic stenting of pancreatic duct either because of its interruption and diastasis between its ends, or in the cases of unsuccessful conservative treatment of external pancreatic fistula caused by drainage of pseudocyst.

2010-01-01

INTRODUCTION. The pharyngocutaneous fistula is clinically detected by appearance of saliva together with deglutition. It is more frequent in postoperative period of total laryngectomies and may to appear in a spontaneous way by dehiscence of pharyngeal suture provoked by deglutition movements of patient or to go with a infection or necrosis. METHODS. A descriptive and bilateral study was conducted on the behavior of pharyngocutaneous fistulas in Cervicofacial Oncology Surgery Service of ''Vladimir Ilich Lenin'' University Hospital in Holguin province. Study sample included all patients operated on by total laryngectomy from 2003 to 2008. There was a total 158 patients and all underwent a manual closure of hypofarynx. RESULTS. Fistulas were present in the 5,6% of cases. The 77,7% of patients had underwent radiotherapy before surgery and the 66,4% of them underwent tracheostomies at surgical operation. In all patients operated on by pharyngotome there was postsurgical sepsis and feeding was started at 10 and 12 days in the 88,4% of cases. CONCLUSIONS. The wide predominance of male patients is directly related to usual toxic habits in this sex. Presurgical tracheostomy is accepted by surgeons as a risk factor for development of fistula, but in present paper wasn't significant. Onset of oral feeding in patients presenting with layngectomies must to fluctuate between 10 and 14 days, never before, but there isn't a hypopharynx healing allowing the foods passage. Also, so it is possible to avoid the appearance of complications like the pharyngocutaneous fistulas. (author)

Causes and management of postoperative enterocutaneous fistulas

Memon, A.S.; Siddiqui, F.G

2004-01-01

Objective: To identify the causes of postoperative enterocutaneous fistulas and to evaluate the results of conservative and operative treatment including the effectiveness of octreotide in the management of these fistulas. Subjects and Methods: Forty patients with postoperative fistula were studied. Demographic variables, causes and management outcome was observed and recorded. Results: There were 25 males and 15 females with 50% of the patients being in age group of 21-30 years. Emergency surgery for typhoid perforation(45%) and intestinal tuberculosis (30%) were the commonest causes. Ileum and jejunum were the commonest sites of fistulation found in 85% cases. Twenty-one patients were started on conservative treatment with spontaneous closure occurring in 15 (71.4%) patients. Nineteen patients were operated within three days of admission due to generalized peritonitis (73.7%) and local intra-abdominal collections (26.3%). Wound infection was the commonest complication in the operative group. The mortality rate in this series was 7.5%. All the deaths occurred following surgery. Conclusion: Postoperative enterocutaneous fistula has a high morbidity and a significant mortality. Sepsis in the peritoneal cavity is the major cause of mortality. Conservative treatment has a good outcome for these fistulas. The use of octreotide is highly recommended as it definitely converts high output fistulas to low output fistulas. (author)

Bronchial and pulmonary scintigraphy with radioactively marked aerosols

Wuerstle, T.

1982-01-01

In 97 patients with bronchitis, bronchial asthma, tuberculosis, sarcoidosis, pneumoconiosis, or tumors the mucociliary clearance and/or deposit pattern after inhalation of radioactively marked aerosols (1 mCi 99m Tc sulfur colloid) was studied. Normal values of the mucociliary 30 min. clearance for the central bronchial/lung periphery are 21%/15%. There was a decreased clearance with bronchitis (11/8%), bronchial asthma, emphysema, tuberculosis, sarcoidosis, trachiobronchial amyloidosis, pleural scarring or interstitial pneumona. Increased clearance (29/19%) was shown with pneumoconiosis. The correlation of deposit pattern and disease, for example, bronchitis, bronchial asthma, bullous emphysema, pleural scarring, partial lung resection, bronchopneumonia, or bronchial restriction, is described. In comparison of aerosol scintigraphy to perfusion scintigraphy and ventilation with gaseous xenon, the aerosol scintigraphy is superior to xenon for certain indications. The aerosol particles, which are larger in comparison to xenon, settle easier by obstructions or flow variations and thereby give better clinical indications of regional differences. (orig.) [de

CLINICAL STUDY OF FISTULA IN ANO

Full Text Available BACKGROUND Fistula in ano is one of the common problem faced in today’s world. Fistula in ano is track lined by granulation tissue that connect deeply in the anal canal or rectum and superficially on the skin around the anus. It usually results from cryptoglandular infection causing abscess, which burst spontaneously or was drained inadequately. The study is conducted to find most common aetiological factor and to evaluate various surgical technique and their outcome. The aim of the study is to- 1. Study the incidence of various aetiologies of fistula in ano. 2. Study the clinical presentation of fistula in ano. 3. Evaluate different modalities of surgical approach and their outcome. MATERIALS AND METHODS This prospective study was conducted at Late Lakhiram Agrawal Memorial Government Medical College, Raigarh, during the study period of July 2015 to July 2016. All the 50 cases were included in this study who were above 15 year of age diagnosed with fistula in ano on the basis of clinical examination who underwent surgical procedure. RESULTS In present study of 50 cases, 60% of cases were in the age group of 31-50 years. Male:female ratio was 9:1. 80% of cases belong to low socioeconomic status. The most common mode of presentation was discharging sinus in 96% of cases. 70% of patient had past history of burst abscess or surgical drainage of abscess. 90% of cases have single external opening. 80% of cases had posterior external opening. Most of the fistula are of low anal type, which was 92% and rest of the patient had an internal opening situated above the anorectal ring. The most common surgical approach done was fistulectomy. Only fistulectomy was done in 80% of patients. Fistulectomy with sphincterectomy was done in two patients. These two patients had associated anal fissure. Fistulectomy with seton placement was done in two patients of high level of fistula type. Fistulotomy was done in four patients (8%, these were of low fistula type

Modified prosthesis for the treatment of malignant esophagotracheal fistula

1988-01-01

Esophagotracheal fistula is usually a sequela of irradiation or laser treatment of advanced carcinoma of the esophagus or the tracheobronchial tree. Resection of the tumor in these cases is not possible, and palliative bypass surgery is highly risky. The peroral placement of a prosthesis is less invasive, but conventional prostheses often fail to occlude the fistula. The authors regularly use an endoscopic multiple-diameter bougie for dilation. After dilation, a specially designed prosthesis is pushed through the tumor stenosis to block the fistula. This procedure can be done without general anesthesia. The funnels of conventional prostheses cannot cover the fistula when there is either a wide, proximal esophagus above the fistula or a high fistula. To cope with this particular situation, a special fistula funnel was developed. It perfectly occludes the fistulas in all patients. Of 21 patients, 19 were discharged without further aspiration

To detect abnormalities of the lower respiratory tract (trachea, principal bronchi, and lobar bronchi) in brachycephalic dogs by use of endoscopy, evaluate the correlation between laryngeal collapse and bronchial abnormalities, and determine whether dogs with bronchial abnormalities have a less favorable postsurgical long-term outcome following correction of brachycephalic syndrome. Prospective case series study. 40 client-owned brachycephalic dogs with stertorous breathing and clinical signs of respiratory distress. Brachycephalic dogs anesthetized for pharyngoscopy and laryngoscopy between January 2007 and June 2008 underwent flexible bronchoscopy for systematic evaluation of the principal and lobar bronchi. For dogs that underwent surgical correction of any component of brachycephalic syndrome, owners rated surgical outcome during a follow-up telephone survey. Correlation between laryngeal collapse and bronchial abnormalities and association between bronchial abnormalities and long-term outcome were assessed. Pugs (n = 20), English Bulldogs (13), and French Bulldogs (7) were affected. A fixed bronchial collapse was recognized in 35 of 40 dogs with a total of 94 bronchial stenoses. Abnormalities were irregularly distributed between hemithoraces; 15 of 94 bronchial abnormalities were detected in the right bronchial system, and 79 of 94 were detected in the left. The left cranial bronchus was the most commonly affected structure, and Pugs were the most severely affected breed. Laryngeal collapse was significantly correlated with severe bronchial collapse; no significant correlation was found between severity of bronchial abnormalities and postsurgical outcome. Bronchial collapse was a common finding in brachycephalic dogs, and long-term postsurgical outcome was not affected by bronchial stenosis.

Of the 604 patients, 24 (4%) reported that their fistulas had been caused by sexual violence; of these, 5 (0.8%) had developed fistulas as a direct result of forced penetration with foreign objects and/or gang rapes. Of the remaining patients, 6 had a fistula before they were raped, 9 developed iatrogenic fistulas following inappropriate instrumentation to manage rape-induced spontaneous abortion or stillbirth, or after abdominal hysterectomy, and 4 developed fistulas after prolonged and obstructed labor. Traumatic fistulas are rare compared to obstetric fistulas. Fistulas indirectly related to sexual violence are likely to be more common than those directly related. All fistulas resulting from sexual violence, whether direct or indirect, should be considered traumatic and special care should be given to these women.

Full Text Available Introduction Collaural fistula or cervico-aural fistula is rare and accounts for less than 8% of branchial cleft anomalies. Their rarity and diverse presentations have frequently led to misdiagnosis and inappropriate treatment. Case Report We report one such case of a 7 year old girl who presented to us with two discharging cutaneous openings on the left side; one in the floor of the left external auditory canal and another in the upper neck and lower face (infra-auricular region. Discussion Surgical exploration and excision is the definitive treatment of a collaural fistula. A sinus/ fistula opening into the external auditory canal, should be removed with skin and cartilage. If more than 30% of the circumference of the external auditory canal is denuded, split thickness skin grafting and stenting are recommended. The potential post-operative complications are facial nerve paralysis and recurrence of the lesion. Fistulogram is a useful diagnostic tool.

Benign duodenocolic fistula (DCF), known as a fistula between the duodenum and colon with or without cecum of nonmalignant origin, is an unusual complication of different gastrointestinal diseases. The present paper records a case in which the patient presented with chronic diarrhea, abdominal pain, weight loss as well as having a history of gastric ulcer. Most frequently the condition presents with signs of malabsorption such as weight loss and diarrhea, but other symptoms include nausea, vomiting (sometimes with fecal), and abdominal pain. Gastrointestinal inflammatory conditions are the usual causes. The most common ones are perforated duodenal ulcer and Crohn's disease. Barium enemas are usually diagnostic. Treatment consists of excising the fistula and repairing the duodenal and colonic defects. Closure of the fistula provides quick relief.

Urinary Tract Infection (UTI) causes a serious health problem and affects millions of people worldwide. Patients with obstetric fistula usually suffer from incontinence of urine and stool, which can predispose them to frequent infections of the urinary tract. Therefore the aim of this study was to determine the etiologic agents, drug resistance pattern of the isolates and associated risk factor for urinary tract infection among fistula patients in Addis Ababa fistula hospital, Ethiopia. Across sectional study was conducted from February to May 2015 at Hamlin Fistula Hospital, Addis Ababa, Ethiopia. Socio-demographic characteristics and other UTI related risk factors were collected from study participants using structured questionnaires. The mid-stream urine was collected and cultured on Cysteine lactose electrolyte deficient agar and blood agar. Antimicrobial susceptibility was done by using disc diffusion method and interpreted according to Clinical and Laboratory Standards Institute (CLSI). Data was entered and analyzed by using SPSS version 20. Out of 210 fistula patients investigated 169(80.5%) of the patient were younger than 25 years. Significant bacteriuria was observed in 122/210(58.1%) and 68(55.7%) of the isolates were from symptomatic cases. E.coli 65(53.7%) were the most common bacterial pathogen isolated followed by Proteus spp. 31(25.4%). Statistical Significant difference was observed with history of previous UTI (P = 0.031) and history of catheterization (P = 0.001). Gram negative bacteria isolates showed high level of resistance (>50%) to gentamicin and ciprofloxacin, while all gram positive bacteria isolated were showed low level of resistance (20-40%) to most of antibiotic tested. The overall prevalence of urinary tract infection among fistula patient is 58.1%. This study showed that the predominant pathogen of UTI were E.coli followed by Proteus spp. It also showed that amoxicillin-clavulanic acid was a drug of choice for urinary tract

Combined radiobronchological examination of patients with chronic pneumonia in the phase of reverse development of the disease has been performed. Severity, localization and extent of bronchial obstruction have been studied, depending on the phase of chronic pneumonia and aspects of lung tissue alterations. Bronchial lesions characteristic of chronic pneumonia were defined, as well as importance of x-ray examination methods for bronchial obstruction diagnosis. Three types of bronchial obstruction were distinguished: bronchoconstriction, bronchodilatation and their combination. With regard to the character and severity of bronchial and pulmonary tissue lesions 3 variants of chronic pneumonia are offered to be differentiated: bronchitic, bronchoectatic, and abscess-forming. The main significance in diagnosis of chronic pneumonia is attributed to combined x-ray examination, which also includes radiobronchological investigation in the first two variants of the disease [ru

Maturation of arteriovenous fistula: Analysis of key factors

Full Text Available The growing proportion of individuals suffering from chronic kidney disease has considerable repercussions for both kidney specialists and primary care. Progressive and permanent renal failure is most frequently treated with hemodialysis. The efficiency of hemodialysis treatment relies on the functional status of vascular access. Determining the type of vascular access has prime significance for maximizing successful maturation of a fistula and avoiding surgical revision. Despite the frequency of arteriovenous fistula procedures, there are no consistent criteria applied before creation of arteriovenous fistulae. Increased prevalence and use of arteriovenous fistulae would result if there were reliable criteria to assess which arteriovenous fistulae are more likely to reach maturity without additional procedures. Published studies assessing the predictive markers of fistula maturation vary to a great extent with regard to definitions, design, study size, patient sample, and clinical factors. As a result, surgeons and specialists must decide which possible risk factors are most likely to occur, as well as which parameters to employ when evaluating the success rate of fistula development in patients awaiting the creation of permanent access. The purpose of this literature review is to discuss the role of patient factors and blood markers in the development of arteriovenous fistulae.

We report a case of complete congenital branchial fistula with an internal opening near the tonsillar fossa. Cysts, fistulas, and sinuses of the second branchial cleft are the most common developmental anomalies arising from the branchial apparatus. In our case, a 43-year-old man presented with a several-year history of a discharging sinus from the right side of his neck, consistent with a branchial fistula. He underwent various investigations and finally was treated with a one-stage complete surgical excision of the fistula tract. We describe the general clinical presentation, investigations, and surgical outcome of this case.

Vesico-vaginal fistula is not life threatening medical problem, but the woman face demoralization, social boycott and even divorce and separation. The aetiology of the condition has been changed over the years and in developed countries obstetrical fistula are rare and they are usually result of gynaecological surgeries or radiotherapy. Urogenital fistula surgery doesn't require special or advance technology but needs experienced urogynaecologist with trained team and post operative care which can restore health, hope and sense of dignity to women. This prospective study was carried out to analyze the success rate in patients attending the referral hospital and sent from free gynaecological surgery camps held at interior of Sindh, and included preoperative evaluation for route of surgery, operative techniques and postoperative care. Total 70 patients were admitted from the patients attending the camp. Out of these, 29 patients had uro-genital fistula. Surgical repair of the fistula was done through vaginal route on 27 patients while 2 required abdominal approach. Out of 29 surgical repairs performed, 27 proved successful. Difficult and complicated fistulae need experienced surgeon. Establishment of separate fistula surgery unit along with appropriate care and expertise accounts for the desired results. (author)

Acquired recto-spinal fistula has been described elsewhere as a rare complication of colorectal malignancy and Crohn's enterocolitis. We treated a young man who developed a recto-spinal fistula as a result of a high fall injury. The patient presented with meningeal signs, sepsis and perianal laceration. Computerized axial tomography revealed air in the supersellar cistern. Gastrografin enema showed that contrast material was leaking from the rectum into the spinal canal. Surgical management included a diverting sigmoid colostomy, sacral bone curettage and wide presacral drainage. To the best of our knowledge, rectospinal fistula of traumatic origin has not been previously reported in the English literature. (orig.)

Full Text Available Jennifer Lindberg,1 Emilie Rickardsson,1 Margrethe Andersen,2 Lars Lund1,2 1Clinical Institute, University of Southern Denmark, Odense, 2Department of Urology, Odense University Hospital, Odense C, Denmark Objective: To establish an animal model of a vesicovaginal fistula that can later be used in the development of new treatment modalities.Materials and methods: Six female pigs of Landrace/Yorkshire breed were used. Vesicotomy was performed through open surgery. An standardized incision between the bladder and the vagina was made, and the mucosa between them was sutured together with absorbable sutures. A durometer ureteral stent was introduced into the fistula, secured with sutures to the bladder wall, allowing for the formation of a persistent fistula tract. Six weeks postoperatively cysto-scopy was performed to examine the fistula in vivo. Thereafter, the pigs were euthanized with intravenous pentobarbital.Results: Two out of four (50% pigs developed persistent fistulas. No per- or postoperative complications occurred.Conclusion: This study indicates that this pig model of vesicovaginal fistula can be an effective and cheap way to create a fistula between the bladder and vagina.

Duodenocolic fistula is a rare complication of malignant colonic disease especially when involving and originating from the sigmoid colon. We aim to discuss the unusual clinical presentation of this case as well as the investigation and management of duodenocolic fistulas. A 91 year old lady presented as an emergency to a general surgical service at a District General Hospital with diarrhoea, vomiting and weight loss. Computed Tomography (CT) reported a large ovarian cyst elevating the sigmoid colon into immediate proximity of the duodenum. Adenocarcinoma was confirmed on histology obtained by colonoscopy. A classic apple core lesion with fistulating tract from the sigmoid colon to the duodenum was synchronously demonstrated on barium enema. Sigmoido-duodenal fistulae represent a complex manifestation of gastrointestinal pathologies. Management options must be considered in the context of patient wishes, their co-morbidities, and predicted post-operative outcome. In most cases this is likely to represent a non-operative approach, however surgical resection may benefit selected cases on occasion. Copyright © 2014 The Authors. Published by Elsevier Ltd..

Full Text Available Colocutaneous fistula caused by diverticulitis is relatively rare, and a delayed recrudescent case of colocutaneous fistula is very uncommon. We herein report a rare case of a Japanese 56-year-old male with delayed recrudescent sigmoidocutaneous fistula due to diverticulitis. A colocutaneous fistula was formed after a drainage operation against a perforation of the sigmoid colon diverticulum. After 5 years from treatment, he was admitted to our hospital because of lower abdominal pain. We diagnosed the recrudescent sigmoidocutaneous fistula by abdominal computed tomography and gastrografin enema, and managed the patient with total parenteral nutrition and antibiotics. As the fistula formation did not improve, a low anterior resection with fistulectomy was performed. The postoperative course was uneventful and the patient was discharged. It has been reported that, in fistulas of the skin caused by diverticular disease, complete closure of the fistula by conservative therapy may not be possible. This case also implies the possibility of a recurrence of the fistula even if the conservative treatment was effective. In cases of colocutaneous fistulas due to diverticulitis, radical surgery is considered necessary because of possibility of recurrence of the fistula.

Objective was to evaluate the efficacy of bronchial arteriography and bronchial artery embolization (BAE) in the management of massive hemoptysis in a developing Asian country. A retrospective review was carried out from March 2000 to March 2005 to evaluate the demographics, clinical presentation, radiographic studies, bronchoscopy results, and complications of bronchial arteriography and BAE at a tertiary care hospital in Pakistan. Fourteen patients (9males, 5 females) with a mean age of 49 years underwent bronchial arteriography and BAE for massive hemoptysis. Hemoptysis was caused by bronchiectasis (10 patients), active pulmonary tuberculosis (3 patients), and lung malignancy (one patient). A CT scan of the chest was carried out in 11 patients, which revealed bronchiectasis (8 patients), cavity with infiltrates (3 patients), and mass lesion (one patient). Bronchoscopy was performed in all patients. Bleeding lobe or segment was identified in 12 patients. Bronchial arteriography revealed hypervascularity (13 patients), bronchial artery hypertrophy (5 patients), hypervascularity with shunting (one patient), dense soft tissue staining (7 patients), extravasation of contrast (one patient) pseudoaneurysm (one patient). Bronchial artery embolization was carried out in all patients. Rebleeding occurred within 24 hours in 2 patients who underwent surgery and within one week another 2 patients who were managed with repeat BAE. The complication of embolization occurred in one patient (transverse myelitis). Thirteen patients improved and were discharged home. One patient with terminal lung carcinoma died due to cardiogenic shock secondary to acute myocardial infarction. Bronchial artery embolization is an effective method for management of massive hemoptysis in developing countries and has a low complication rate. (author)

We report our experience in using Guglielmi electrolytically detachable coils (GDC) alone or in combination with other materials in the treatment of intracranial or cervical high-flow fistulae. We treated 14 patients with arteriovenous fistulae on brain-supplying vessels - three involving the external carotid or the vertebral artery, five the cavernous sinus and six the dural sinuses - by endovascular occlusion using electrolytically detachable platinum coils. The fistula was caused by trauma in six cases. In one case Ehlers-Danlos syndrome was the underlying disease, and in the remaining seven cases no aetiology could be found. Fistulae of the external carotid and vertebral arteries and caroticocavernous fistulae were reached via the transarterial route, while in all dural fistulae a combined transarterial-transvenous approach was chosen. All fistulae were treated using electrolytically detachable coils. While small fistulae could be occluded with electrolytically detachable coils alone, large fistulae were treated by using coils to build a stable basket for other types of coil or balloons. In 11 of the 14 patients, endovascular treatment resulted in complete occlusion of the fistula; in the remaining three occlusion was subtotal. Symptoms and signs were completely abolished by this treatment in 12 patients and reduced in 2. On clinical and neuroradiological follow-up (mean 16 months) no reappearance of symptoms was recorded.

Enterovesical fistula is a relatively rare condition in Crohn's disease. This study was undertaken to examine clinicopathological features and management of enterovesical fistula complicating Crohn's disease. Thirty patients with enterovesical fistula complicating Crohn's disease, treated between 1970 and 1997, were reviewed. Urological symptoms were present in 22 patients; pneumaturia in 18, urinary tract infection in 7, and haematuria in 2. In 5 patients clinical symptoms were successfully managed by conservative treatment, and they required no surgical treatment for enterovesical fistula. Twenty-five patients required surgery. All the patients were treated by resection of diseased bowel and pinching off the dome of the bladder. No patients required resection of the bladder. The Foley catheter was left in situ for an average of 2 weeks after operation. Three patients developed early postoperative complications; two bowel anastomotic leaks, and one intra-abdominal abscess. All these complications were associated with sepsis and multiple fistulas at the time of laparotomy. After a median follow-up of 13 years, 3 patients having postoperative sepsis (anastomotic leak or abscess) developed a recurrent fistula from the ileocolonic anastomosis to the bladder, which required further surgery. In the other 22 patients without postoperative complications there has been no fistula recurrence. In conclusion, the majority of patients with enterovesical fistula required surgical treatment: resection of the diseased bowel and oversewing the defect in the bladder. The fistula recurrence was uncommon, but the presence of sepsis and multiple fistulas at the time of laparotomy increased the incidence of postoperative complications and fistula recurrence.

Objective: To investigate the safety and the effect of superselective bronchial artery chemoembolization in the treatment of lung cancer. Methods: Three hundred and twenty-nine cases of lung cancer diagnosed by pathology and treated with simply bronchial artery infusion or superselective bronchial artery chemoembolization were investigated. (1) Simply bronchial artery infusion (n=221): 40-60 mg Cisplatin or 200-300 mg Carboplatin combined with 10-20 mg Mitomycin-C or 100-200 mg Etoposide were infused through the catheter which was placed in the bronchial artery trunk or intercostal-bronchial artery trunk after angiography, re-infusion was performed at 2-4 weeks intervals, 549 times of infusion were performed in 221 cases. (2) Superselective bronchial artery chemoembolization (n=108): microcatheter was superselectively inserted into the distal of feeding artery guided with road-map after selective angiography, then anticarcinogen (same as simply bronchial artery infusion) and embolic material were infused through microcatheter. 30-50 Gelfoam particles and/or 3-8 ml Lipiodol was used as embolic material. Chemoembolization was reperformed at 6-9 weeks intervals, 266 times of chemoembolization were done in 108 cases. Results: No severe complications such as spinal injury were found. 28 cases in 221 cases performed with simply bronchial infusion got complete response (CR), meanwhile, partial response (PR) in 79 cases, stable(S) in 88 cases, and processes (P) in 26 cases. The effective rate (CR + PR) was 48.4%, survival rate of 1 year and 2 years were 53.8% and 44.8%, respectively. In the 108 cases performed with superselective bronchial artery chemoembolization, there were 16 cases of CR, 53 cases of PR, 32 cases of S, and 7 cases of P. The effective rate (CR + PR) was 63.9%, survival rate of 1 year and 2 years were 77.8% and 65.7%, respectively. There were significant statistic differences in the effective rate and survival rate of 1 year and 2 years between the two

An analysis of bronchial mucus proteins was carried out by crossed immunoelectrophoresis. Before electrophoretic migration, sputum was treated with Ecteola-cellulose, which retains acid mucins. The proteins were then extracted by a phosphate/saline buffer pH 7.5. Crossed immunoelectrophoresis of the "bronchial extracts" was carried out with an anti-human serum: fifteen proteins were detected. Among them, IgA and protease inhibitiors play an important role in bronchial pathology. Bronchial extracts were also studied with immune serums against milk proteins, whole saliva and proteins of bronchial mucus. Bronchotransferrin, amylase and two esterases were characterized. Four other proteins were also detected with immune serums against bronchial mucus-proteins: their biological role is still unknown.

Uro-genital fistulas, majority of which are vesico-vaginal fistulas (VVF), are a great challenge for women in developing countries. It is commonly caused by prolong obstructed labour and is one of the worst complications of child birth and poor obstetric care. The objective of this descriptive study was to review the cases of genitourinary fistulae so as to understand the magnitude of the problem and its aetiology and to share our experience of surgical repair with other specialists in this field. The study was conducted at Gynaecological Unit-II, Liaquat University Hospital Hyderabad, Pakistan from June 1996 to December 2007. The case records of all patients admitted and managed during study period were reviewed. The information regarding characteristics, risk factors and surgical management was collected. The data was analysed by SPSS and mean, range, standard deviation and percentage were calculated. During the study period, 278 patients with genitourinary fistulae were admitted and managed. The mean age of patients with urinary fistulae was 31.5+-7.5 years, parity was 4.2+-2.8, and duration of labour was 38.4+-6.5 hours. The duration of fistulae ranged from 1 day to 25 years. Obstructed labour 246 (88.4%) was the most common cause of urinary fistulae, followed by gynaecological surgeries mainly hysterectomies 26 (9.35%). The most common type of urinary fistula was vesico-vaginal fistula (VVF) 250 (89.9%). A total of 268 underwent surgery. Almost all 261 (97.3%) urinary fistulae were repaired transvaginally except patients with ureterovaginal and vesico-uterine fistulae. The most common surgical procedure used was layered closure. Martius graft was used in 3 (1.1%) patients, who required creation of new urethra. The success rate following first, second and third attempt was 85%, 91% and 96% respectively. Urogenital fistulae are rarity in developed world, but are frequently encountered problem in developing countries like Pakistan, often resulting from prolonged

Chronic Pulmonary Aspergillosis Complicating Bronchial Atresia

Full Text Available Bronchial atresia is a rare pulmonary developmental anomaly characterized by the presence of a focal obliteration of a segmental or lobar bronchial lumen. The lung distal to the atretic bronchus is typically emphysematous along with the presence of mucus filled ectatic bronchi (mucoceles. BA is usually asymptomatic but pulmonary infections can rarely develop in the emphysematous lung distal to the atretic bronchus. We present a unique case of chronic pulmonary aspergillosis (CPA in a patient with BA with no evidence of immune dysfunction. The patient was treated initially with voriconazole and subsequently underwent surgical excision of the involved area. On follow-up, she has done extremely well with no evidence for recurrence. In summary, we describe the first case of chronic pulmonary aspergillosis in an immunocompetent patient with bronchial atresia.

Full Text Available Anterior palatal fistulae or residual anterior clefts are a frequent problem following palatoplasty. Various techniques have been used to repair such fistulae, each having its own advantages and disadvantages. We have successfully used orbicularis oris musculomucosal flap to close anterior fistula and residual clefts in 25 patients. This study shows the superiority of this flap over other techniques because of its reliable blood supply, easy elevation and transfer to fistula site and finally because it is a single-stage procedure.

The tentorial artery is often involved in arterial supply to tentorial dural fistulas. The hypertrophied tentorial artery is accessible to embolization, either with glue or with particles. Six patients are presented with tentorial dural fistulas, mainly supplied by the tentorial artery. Two patients presented with intracranial hemorrhage, two with pulsatile tinnitus and one with progressive tetraparesis, and in one patient the tentorial dural fistula was an incidental finding. Different endovascular techniques were used to embolize the tentorial artery in the process of endovascular occlusion of the fistulas. All six tentorial dural fistulas were completely occluded by endovascular techniques, confirmed at follow-up angiography. There were no complications. When direct catheterization of the tentorial artery was possible, glue injection with temporary balloon occlusion of the internal carotid artery at the level of the tentorial artery origin was effective and safe. Different endovascular techniques may be successfully applied to embolize the tentorial artery in the treatment of tentorial dural fistulas. (orig.)

A case of rectovesicovaginal fistula caused by pelvic radiation for uterine cancer is presented. A 62-year-old woman visited our department complaining of macroscopic hematuria, mictional pain and pollakisuria. She had a history of total hysterectomy and radiation therapy for cervical cancer 26 years earlier. Melena was noted in March 1994 and an escape of stool from the vagina followed nine months later. She consulted a surgeon about it, however no active treatment was performed before coming under our care. Computed tomography demonstrated that the posterior bladder wall was extremely thin and the possibility of the formation of vesical perforation was strongly suggested. We constructed transverse-colostomy, however, a rectovesicovaginal fistula developed seven months later. Therefore, in order to regain a dry life, an ileal conduit was constructed and her quality of life began to improve. It is probable that the rectovesicovaginal fistula could have been prevented if colostomy had been carried out soon after the appearance of melena or soon after the formation of the rectovaginal fistula.

A case of rectovesicovaginal fistula caused by pelvic radiation for uterine cancer is presented. A 62-year-old woman visited our department complaining of macroscopic hematuria, mictional pain and pollakisuria. She had a history of total hysterectomy and radiation therapy for cervical cancer 26 years earlier. Melena was noted in March 1994 and an escape of stool from the vagina followed nine months later. She consulted a surgeon about it, however no active treatment was performed before coming under our care. Computed tomography demonstrated that the posterior bladder wall was extremely thin and the possibility of the formation of vesical perforation was strongly suggested. We constructed transverse-colostomy, however, a rectovesicovaginal fistula developed seven months later. Therefore, in order to regain a dry life, an ileal conduit was constructed and her quality of life began to improve. It is probable that the rectovesicovaginal fistula could have been prevented if colostomy had been carried out soon after the appearance of melena or soon after the formation of the rectovaginal fistula.

Stenosis of arteriovenous (A-V) fistulae secondary to neointimal hyperplasia (NIH) compromises dialysis delivery, which worsens patients' quality of life and increases medical costs associated with the maintenance of vascular accesses. In the present study, we evaluated the role of the receptor tyrosine kinase c-Kit in A-V fistula neointima formation. Initially, c-Kit was found in the neointima and adventitia of human brachiobasilic fistulae, whereas it was barely detectable in control veins harvested at the time of access creation. Using the rat A-V fistula model to study venous vascular remodeling, we analyzed the spatial and temporal pattern of c-Kit expression in the fistula wall. Interestingly, c-Kit immunoreactivity increased with time after anastomosis, which concurred with the accumulation of cells in the venous intima. In addition, c-Kit expression in A-V fistulae was positively altered by chronic kidney failure conditions. Both blockade of c-Kit with imatinib mesylate (Gleevec) and inhibition of stem cell factor production with a specific short hairpin RNA prevented NIH in the outflow vein of experimental fistulae. In agreement with these data, impaired c-Kit activity compromised the development of NIH in A-V fistulae created in c-KitW/Wv mutant mice. These results suggest that targeting of the c-Kit signaling pathway may be an effective approach to prevent postoperative NIH in A-V fistulae. PMID:25186298

Full Text Available Background and objective Treating airway fistulas, including esophagorespiratory fistulas (ERFs, bronchopleural fistulas (BPFs, and tracheomediastinal fistulas (TMFs, is difficult. The aim of this study is to evaluate the safety and clinical efficacy of metallic covered Z-type stents (CZTS for the treatment of airway fistulas through bronchoscopy or fluroscopy. Methods Thirty-eight patients with fistulas between the esophagus, mediastina, and airways (32 ERFs, 5 BPFs, and 1 TMF were retrospectively reviewed after treatment with covered metallic esophageal and airway stents. The fistulas were caused by esophageal (n=26, bronchogenic (n=11, and thyroid (n=1 carcinomas. Results Forty-six fistulas were found in 38 patients. The fistula size ranged from 0.5 cm to 7.0 cm. Forty airway covered metal stents (24 Y-type, 8 L-type, and 8 I-type and 24 esophageal metal stents were placed. Complete responses to the sealing effects of fistulas were noted in 4.3% of all the fistulas, 60.9% showed complete clinical responses, 23.9% showed partial responses, and 10.9% showed no response. An effectivity rate of 89.1% was observed, and the median survival duration of all patients was 5 months. Conclusion The use of CZTS appears to be safe and feasible for the palliative treatment of ERFs, BPFs, and TMFs. Airway stent placement is recommended for patients with ERF. In the event that airway stents fail, esophageal stents should be given. Airway bifurcation stents were observed to be especially suitable for the sealing of fistulas near the trachea carina.

Transarterial chemoembolization (TACE) is a common treatment modality to locally manage hepatocellular carcinoma. Liver abscess and bile duct injury are common complications of TACE. However, hepatobronchial fistula is a rare complication. Herein, we report a case of lung abscess due to hepatobronchial fistula after TACE. A 67-year-old man, who had underwent TACE 6 months ago, presented cough and bile-colored sputum. He was diagnosed with lung abscess and hepatobronchial fistula. We performed endoscopic retrograde cholangiopancreatography; however, there was no improvement in his symptoms. Thereafter, partial hepatectomy and repair of fistula were successively conducted.

Carotid cavernous fistulas are pathologic connections between the internal and/or external carotid artery and the cavernous sinus. According to Barrow one can distinguish between direct (high flow) and indirect (low flow) fistulas, whereby direct fistulas are often traumatic while indirect fistulas more frequently occur spontaneously in postmenopausal women. Diagnosis can easily be established using MRI and angiography, which allow exact visualization of the anatomy of fistulas to plan the interventional neurological therapy that in recent years has replaced surgical therapy. This article provides an overview on imaging findings, diagnosis using MRI and angiography as well as interventional treatment strategies. (orig.) [de

[Diagnostic and therapeutic concepts for vesicovaginal and ureterovaginal fistulas].

2018-02-01

 Vesico- and ureterovaginal fistulas are defined as abnormal connections between the urinary tract, on the one side, and the female genital system, on the other. Despite being highly prevalent as an acquired pathology of the urogenital system, there has as yet been no standardized protocol in place for diagnosing and treating these fistulas. This review analyses the current literature concerning vesico- and ureterovaginal fistulas in order to profile common diagnostic and therapeutic concepts.  Literature research was carried out using the data bases of Medline and PubMed. A general internet research was added as well as the subsequent analysis of textbooks. Subsequently 40 scientific publications, four textbooks and one internet source were consulted.  In the diagnostic process of not only vesicovaginal, but also ureterovaginal fistulas a timely vaginal examination followed by a cystoscopy and further imaging by retrograde vaginal methylene blue instillation should be carried out. In order to further the differential diagnosis of ureterovaginal fistulas in particular, additional imaging techniques may be required. However, the therapies of both fistulas manifest essential differences. Ureterovaginal fistulas are closed in a two-stage procedure. At first, a percutaneous nephrostomy is placed to decompress the renal collecting system and further drain the urine, followed by a second intervention, which closes the fistula. The management of vesicovaginal fistulas includes both conservative and surgical concepts, the latter of which may in turn be divided into a transabdominal and/or a transvaginal approach. Essentially, transabdominal fistula surgery should, at first, include the identification of the orifices of both ureters to subsequently splint them as indicated. This should be followed by the excision of the fistula. In the case of large fistulas a flap reconstruction of the area may be considered after the mobilisation of the surrounding tissue. Despite

The purpose of this study was to determine non-invasively the frequency of ectopic bronchial arteries (BA) (i.e., bronchial arteries originating at a level of the descending aorta other than T5-T6 or from any aortic collateral vessel) on multidetector-row CT angiograms (CTA) obtained in patients with hemoptysis. Over a 5-year period (2000-2005), 251 consecutive patients with hemoptysis underwent multidetector-row CT angiography of the thorax. From this population, 37 patients were excluded because of a suboptimal CTA examination (n = 19), the presence of extensive mediastinal disease (n = 15) or severe chest deformation (n = 3) precluding any precise analysis of the bronchial arteries at CTA. Our final study group included 214 patients who underwent a thin-collimated CT angiogram (contrast agent: 300 to 350 mg/ml) on a 4- (n = 56), 16- (n = 119) and 64- (n = 39) detector-row scanner. The site of origin and distribution of bronchial arteries were analyzed on transverse CT scans, maximum intensity projections and volume-rendered images. The site of the ostium of a bronchial artery was coded as orthotopic when the artery originated from the descending aorta between the levels of the fifth and sixth thoracic vertebrae; all other bronchial arteries were considered ectopic. From the studied population, 137 (64%) patients had only orthotopic bronchial arteries, whereas 77 patients (36%) had at least one bronchial artery of ectopic origin. A total of 147 ectopic arteries were depicted, originating as common bronchial trunks (n = 23; 19%) or isolated right or left bronchial arteries (n = 101; 81%). The most frequent sites of origin of the 124 ostiums were the concavity of the aortic arch (92/124; 74%), the subclavian artery (13/124; 10.5%) and the descending aorta (10/124; 8.5%). The isolated ectopic bronchial arteries supplied the ipsilateral lung in all but three cases. Bronchial artery embolization was indicated in 26 patients. On the basis of CTA information, (1

Objectives: To evaluate the outcome of trans-vaginal repair of vesico-vaginal fistula through vaginal approach. Study Design: Prospective study. Material and Methods: This study was carried out in Department of Urology, Shaikh Zayed Postgraduate Medical Institute and National institute of Kidney Diseases, Lahore for the period extending from April 2009 to April 2014. Total 17 patients were included in the study. History, physical examination and findings on investigations were reviewed. In all patients cystoscopy and vaginal examination was performed to see fistula site and ureteral orfices. Then trans-vaginal repair was done in all cases. Results: VVF repair was performed on 17 patients aging 25 to 45 years (mean 35.83 ± 7.37 years). The symptoms preceded for a period of 3 months to 8 years. The cause was gynecological hysterectomy 8 (47.05%), obstetric C-section 7 (41.17%) and obstructed labor 2(11.76%). In three of our patients VVF was previously repaired trans-abdominally. On cystoscopy no patients had more than one fistula. In two (11.76%) patients fistula was supratrigonal. The average size of fistula was 2.05 em, detail of fistula site and size is given in table. One patient had leakage on second postop day that was managed with change of Foleys catheter. Successful repair was achieved in all patients and no patient required second attempt. No ureteric injury and other complications were observed. Conclusion: Trans-vaginal repair of VVF avoid laparotomy and bladder bisection. It has reduced hospital stay and morbidity. (author)

Bronchial rupture is a rare and serious complication of blunt chest trauma in children. The diagnosis of this injury is challenging and requires a high degree of clinical suspicion. It is frequently associated with other severe injuries that may draw the focus of attention away from this potentially catastrophic but treatable injury. The radiographic findings of bronchial rupture have been reported in very few series. We report the findings in two children with bronchial rupture diagnosed by CT, in whom CT resulted in a significant change in patient management. (orig.)

The transgenic arteriovenous fistula model, surgically constructed with transgenic mouse aorta interposed in common carotid artery-to-external jugular vein fistulae in nude rats, has a 4-month experimental window because patency and transgenic phenotype are lost over time. We adapted this model to investigate occlusive arteriopathy in brain arteriovenous malformations after radiosurgery by radiating grafted aorta before insertion in the fistula. We hypothesized that high-dose radiation would reproduce the arteriopathy observed clinically within the experimental time window and that deletions of endoglin (ENG) and endothelial nitric oxide synthase (eNOS) genes would modify the radiation response. Radiation arteriopathy in the common carotid arteries of 171 wild-type mice was examined with doses of 25, 80, 120, or 200 Gy (Experiment 1). Radiation arteriopathy in 68 wild-type arteriovenous fistulae was examined histologically and morphometrically with preoperative radiation doses of 0, 25, or 200 Gy (Experiment 2). Radiation arteriopathy in 51 transgenic arteriovenous fistulae (36 ENG and 15 eNOS knock-out fistulae) was examined using preoperative radiation doses of 0, 25, or 200 Gy (Experiment 3). High-dose radiation (200 Gy) of mouse common carotid arteries induced only mild arteriopathy (mean score, 0.66) without intimal hyperplasia and with high mortality (68%). Radiation arteriopathy in wild-type arteriovenous fistulae was severe (mean score, 3.5 at 200 Gy), with intimal hyperplasia and medial disruption at 3 months, decreasing luminal areas with increasing dose, and no mortality. Arteriopathy was robust in transgenic arteriovenous fistulae with ENG +/- and with eNOS +/-, with thick intimal hyperplasia in the former and distinct smooth muscle cell proliferation in the latter. The transgenic arteriovenous fistula model can be adapted to rapidly reproduce radiation arteriopathy observed in resected brain arteriovenous malformations after radiosurgery. High

The purpose of this study is to retrospectively examine the postoperative pulmonary fistula as a complication after the use of either electrocautery or a harmonic scalpel without stapling devices. The subjects of this study consisted of 28 patients who received a segmentectomy for a pulmonary malignant tumor, 25 cases of lung cancer and 3 of metastatic lung tumor. The electrocautery was used in 17 patients (EC group) and the harmonic scalpel in 11 (HS group). The levels of postoperative air leakage and postoperative complications were examined among the two groups retrospectively. The histological findings of the cut surface of the segmentectomy by electrocautery and harmonic scalpel were also examined. Hemostasis and air leakage both were well controlled during the operation, and the postoperative drainage period was short. No major postoperative complications occurred, and all patients began walking in the early postoperative days. However, 1 to 3 postoperative months after discharge, 8 patients showed late onset of a pulmonary fistula, 3 of the 17 (18%) in the EC group and 5 of the 11 (45%) in the HS group. The histological findings of the cut surface of the segmentectomy showed that most of the layer of coagulation necrosis by the harmonic scalpel measured 2 mm thick, and it was denser than that cut from electrocautery. The lumen of the bronchus markedly decreased in size, but it remained, as it also did under the effects of electrocautery. In the months following the operation, the incidence of the late onset of a pulmonary fistula was higher when the harmonic scalpel was used. It was believed that the small bronchial stump could not tolerate the airway pressure because the thick coagulation necrosis delayed healing of the postoperative wound. It was necessary to ligate the stump of a small bronchus, even though the stump had been temporally closed by coagulation necrosis with the electrocautery or harmonic scalpel during the operation.

Full Text Available Allthough infrequent, digestive fistulae in HIV/AIDS patients have been reported throughout the digestive tract from the esophagus to the anus, with predominance of esophageal fistulae. AIDS/HIV-associated opportunistic infections may invade the digestive system and lead to fistula formation. Tuberculosis is the most common infection associated with these esophageal fistulae. We report here one case of bile duct-duodenal fistula in a female AIDS patient with associated abdominal Mycobacterium tuberculosis infection compromising lymphnodes of the hepatic pedicle where the fistula was found. According to the reviewed literature, this is the third case of bile duct-duodenal fistula associated with abdominal tuberculosis in AIDS patient, and the first where both the fistula and the tuberculosis infection were diagnosed at laparotomy for acute abdomen. Whether the AIDS patient with abdominal pain needs or not a laparotomy to treat an infectious disease is often a difficult matter for the surgeon to decide, as most of the times appropriate medical treatment will bring more benefit.

Full Text Available   Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. General characteristics of the patients including age, gender, etiology, and thorax computed tomograms, findings of bronchial angiographic, results of the embolization, complications related to bronchial artery embolization and clinical outcome during follow-up were reviewed. Results: The etiology included previous pulmonary tuberculosis in 20 cases, previous tuberculosis with bronchiectasis in 16 cases, bronchiectasis in 6 cases, and active pulmonary tuberculosis in one case. No identifiable causes could be detected in three patients. Moreover, massive hemoptysis was successfully and immediately controlled following the embolization procedure in all patients. One patient developed recurrent hemoptysis during one month following the procedure and was treated by re-embolization. No major procedure–related complication such as bronchial infarction was identified However none of the patientsexperienced neurological complications. Conclusion: Bronchial artery embolization is a safe and effective means of controlling massive hemoptysis and should be regarded as the first-line treatment for this condition.

Objective: Vesicovaginal and ureterovaginal fistulas are unusual complications secondary to pelvic surgery or pelvic diseases. The therapeutic success in these cases depends on an appropriate preoperative evaluation for diagnosis and visualization of the fistulous tract. The present study is aimed at demonstrating the potential of magnetic resonance urography for the diagnosis of vesicovaginal and ureterovaginal fistulas as well as for defining the fistulous tracts. Materials And Methods: Seven female patients clinically diagnosed with vesicovaginal or ureterovaginal fistulas had their medical records, radiological and magnetic resonance images retrospectively reviewed. Magnetic resonance urography included 3D-HASTE sequences with fat saturation. Results: Six patients presented vesicovaginal fistulas and, in one patient, a right-sided ureterovaginal fistula was diagnosed. Magnetic resonance urography allowed the demonstration of the fistulous tract in six (85.7%) of the seven patients evaluated in the present study, without the need of bladder catheterization or contrast injection. Conclusion: This study demonstrates both the potential and applicability of magnetic resonance urography in the evaluation of these types of fistulas. (author)

Non-matured arteriovenous fistulae for haemodialysis: diagnosis, endovascular and surgical treatment

Directory of Open Access Journals (Sweden)

Marko Malovrh

2010-04-01

Full Text Available Non-maturation is a feature of autologous vascular access. The autologous arteriovenous fistula needs time to mature and for the vein to enlarge to a size where it can be needled for dialysis. A fistula that fails early is one that either never develops adequately to support dialysis or fails within the first three months of its use. Two variables are required for fistula maturation. Firstly, the fistula should have adequate blood flow to support dialysis and secondly, it should have enough size to allow for successful repetitive cannulation. Three main reasons for maturation failure are: arterial and venous problems and the presence of accessory veins. Early diagnostics and intervention for fistula maturation minimizes catheter use and its associated complications. The identification of immature fistulae is relatively simple. Physical examination has been highlighted to be a valuable tool in assessing fistula. Any fistula that fails to mature adequately and demonstrates abnormal physical findings should be studied aggressively. Ultrasonography can successfully identify candidates who fail to meet the recently developed criteria for immature fistulae. In recent years, digital subtraction angiography and contrast-enhanced magnetic resonance angiography has been introduced for assessment of dysfunctional haemodialysis conduits, including immature fistulae. A great majority of non-matured fistulae can be successfully salvaged using percutaneous techniques. In addition to endovascular techniques, surgical intervention can also be an option. This paper reviews the process of fistula maturation and presents information regarding how to obtain a mature fistula.

Teixeira, Sérgio; Costa, Joana; Bartosch, Isabel; Correia, Bernardo; Silva, Álvaro

2017-06-01

Pharyngocutaneous fistula is a common complication of laryngopharyngeal surgery and is associated with increased morbidity and mortality. Beyond the classical management, negative-pressure wound therapy (NPWT) can be an alternative and effective treatment. Two patients with pT3N0M0 squamous cell carcinoma of pyriform sinus were subjected to total laryngectomy and pharyngoesophageal reconstruction of a circular (patient 1) and an anterior wall defect (patient 2) with radial forearm free flap and pectoralis major muscle flap, respectively. Both developed a pharyngocutaneous fistula and NPWT was used.A significant decrease of the fistula aperture and exudate was observed after 22 and 21 days of NPWT in patients 1 and 2, respectively. After that standard wound care was instituted and closure of the fistulae was accomplished in 5 and 7 days, respectively. Negative-pressure wound therapy can be an effective treatment for pharyngocutaneous fistula closure, either in the setting of fistulae that persist besides multiple surgical revisions using muscle flaps or as a first-line therapy when fistulae develops.

The records of 23 patients with vesicovaginal fistulae (VVF) probably caused by irradiation treatment for cancer of the uterine cervix were analyzed. The median latency between irradiation and fistula formation was 17 years. Ten patients had histologically verified cancer recurrence besides a VVF. In addition, nine patients had a rectovaginal- and one an ileovaginal fistula. Twelve patients were treated primarily with ureteroileocutaneostomy a.m. Bricker. Six had bladder drainage, and four of these had ureteroileocutaneostomy performed at a later stage. Four patients initially underwent percutaneous nephrostomy. One patients had a unilateral ureteroileocutaneostomy performed. Eight patients are alive today (median observation time 2.5 years), and all of these had had ureteroileocutaneostomy performed. Three of these patients (39%) were completely relieved of symptoms while the rest occasionally experienced pain, vaginal discharge and bladder empyema. We conclude that ureteroilocutaneostomy a.m. Bricker is a satisfactory procedure for vesicovaginal fistulae because the socially incapacitating symptoms disappear or are considerably diminished.

Rangel, Alberto; Muñoz-Castellanos, Luis; Solorio, Sergio

2003-01-01

The authors present the clinical cases of three adult patients (49, 53 and 61 year-old), with rheumatic cardiac valvulopathy, and bilateral coronary arteriovenous fistulae draining in the main pulmonary artery. Based on documental investigation, the authors speculate about the predeterminate origin of coronary arteriovenous fistulae. At first glance, it seems obvious that congenital cardiopathies occur at random, i.e., embryonic development deviate or stops due to unknown reasons, originating the persistence of lacunar blood spaces prior to the development of coronary arteries cords. There are two factors involved in the genesis of congenital malformations: a genomic preexisting factor and the presence of an environmental precipitating factor, i.e., isolated pulmonary valve atresia or left ventricular hypoplastic syndrome, with mitral and aortic valve stenosis, can predispose development of coronary arteriovenous fistulae. Recently, the question has been raised whether there is a relation of coronary arteries fistulae with: ethnic groups, hereditary gigantism, autoimmune diseases, such as polymyositis, hereditary hemorrhagic telangiectasia, and apical hypertrophic myocardiopathy. Coronary arteriovenous fistulae, as well as some congenital cardiopathies, could be due to chromosome alterations or might be related to hereditary diseases, such as hemorrhagic telangiectasia, induced by a disturbed genetic program. Although, there is no concrete evidence that a genetic factor is related to the development of coronary arteriovenous fistulae, there are signs that suggest that such a possibility could be investigated.

2002-01-01

A 70-year-old man with recurrent undiagnosed episodes of bronchial cast expectoration and pulmonary infiltrates on chest radiography for 15 years is described. The diagnosis of chyloptysis was established by chemical analysis of the bronchial aspiration. We emphasize the radiological findings of this rare observation. The CT-associated lymphangiography showed mediastinal lymphangiectasis with retrograde opacification of mediastinal and hilar lymph nodes as well as submucosal lymphatic vessels protruding into the lumen of the tracheo-bronchial tree without evidence of thoracic duct obstruction as well as a ''crazy-paving appearance.'' Congenital incompetence of the valves of the lymphatic vessels originating from the thoracic duct is held to be the cause. Chyloptysis and pulmonary lymphatic disorder should be sought in cases of bronchial cast expectoration. (orig.)

Sellars, N.; Belli, A.M.

2001-01-01

Two patients presented with recurrent, massive haemoptysis. Arteriography, including thoracoabdominal aortograms, revealed in both cases large non-bronchial collaterals arising from the left gastric artery. In the first case the non-bronchial collateral supplied the upper left lobe and in the second case it supplied the middle right lobe. Percutaneous embolisation of bronchial and non-bronchial collateral branches has become an accepted procedure in controlling massive or recurrent haemoptysis. Accurate identification of the non-bronchial collateral arterial feeders is essential for successful embolotherapy. (orig.)

Objective: To evaluate the pulmonary metastatic tumor response to different ways of transcatheter arterial infusion. Methods: Thirty-five patients with pulmonary metastatic tumors were randomized divided into two groups: 15 patients with 49 lesions treated with bronchial arterial infusion (BAI) and 20 patients with 65 lesions treated with bronchial arterial infusion (BM)combined with pulmonary arterial infusion (PAI). The therapeutic response was assessed by the WHO evaluation criteria. Results: The total effective rate(CR + PR) of BAI was 65.3% (32/49), PAI + BAI was 61.5%(40/65) showing no statistical difference. The median survival time of BAI was 9 mo, BAI + PAI was 11.5 mo, demonstrating no statistical significance. Conclusions: BAI should be the primary treatment for pulmonary metastatic tumor. (authors)

Bronchial Thermoplasty in Asthma

Directory of Open Access Journals (Sweden)

Wayne Mitzner

2006-01-01

Full Text Available In this review we discuss the potential of a new procedure, termed Bronchial Thermoplasty to prevent serious consequences resulting from excessive airway narrowing. The most important factor in minimizing an asthmatic attack is limiting the degree of smooth muscle shortening. The premise that airway smooth muscle can be either inactivated or obliterated without any long-term alteration of other lung tissues, and that airway function will remain normal, albeit with reduced bronchoconstriction, has now been demonstrated in dogs, a subset of normal subjects, and mild asthmatics. Bronchial Thermoplasty may thus develop into a useful clinical procedure to effectively impair the ability for airway smooth muscle to reach the levels of pathologic narrowing that characterizes an asthma attack. It may also enable more successful treatment of asthma patients who are unresponsive to more conventional therapies. Whether this will remain stable for the lifetime of the patient still remains to be determined, but at the present time, there are no indications that the smooth muscle contractility will return. This successful preliminary experience showing that Bronchial Thermoplasty could be safely performed in patients with asthma has led to an ongoing clinical trial at a number of sites in Europe and North America designed to examine the effectiveness of this procedure in subjects with moderately severe asthma.

Thirteen bronchial arterial perfusion studies were performed in a total of 13 patients with lung tumors (11 cases of lung cancer, one metastatic tumor and one abscess), utilizing 99m TcO 4 - or 99m Tc-labeled macroaggregated albumin ( 99m Tc-MAA). Regions of interest (ROI) of the same size were set over areas of tumor, the mediastinum and healthy lung areas, and each ROI count was calculated by a nuclear medicine computer during an acquisition time period of 20 min with each tracer for 7 min to evaluate tumor part perfusion. The count ratios of tumor to healthy parts ranged from 1.7 to 6.5 (mean±s.d.; 3.8±1.9) in the 99m TcO 4 - group (10 patients) and from 130 to 230 (mean±s.d.; 163±30) in the 99m Tc-MAA group (3 patients), respectively. Tumor reduction rates 2 weeks after CDDP bronchial artery infusion therapy correlated positively to the count ratio in the 99m TcO 4 - lung cancer group, although significant correlation was not obtained. This study suggests that bronchial arterial infusion of anticancer agents may result in higher concentrations of anticancer agents in the tumors than with systemic chemotherapy and chemoembolic materials may exert more potent anticancer effects on tumors than nonparticulated anticancer agents.

Our aim was to confirm the usefulness of magnetic resonance in the evaluation of perianal fistulas, and in conjunction with a thought anatomical review of affected areas. This would allow for the building of a proper surgical plan, which would necessarily differ according to the fistula's complexity. We studied 75 patients with perianal fistulas and performed 81 MR studies by means of axial, sagittal and coronal T1 and T2 sequences. Fistula type, degree, etiology and correlation to surgical findings were all studied. Fifty-five patients underwent surgical treatment, and 26 underwent a more conservative treatment with MR follow-up. Ninety-nine fistulas were observed and classified according to norms set down by St. James University Hospital. Of the 55 cases submitted to surgery, 46 showed concordance between the surgical report and MR, whose sensitivity was 84%. In 9 patients, there was no correlation. In the study of perianal fistulas, it is important to establish both the fistulous tract and relationship to the sphincter complex. MR permits an identification of the sprinter complex and a more precise anatomical localization of the fistulous trajectory. It is also capable of differentiating between fibrosis and abscess. Therefore, MR is an appropriate technique for the study of perianal fistulas and related surgical planning. (Author) 6 refs.

A 7-year-old girl with a right-sided congenital arteriovenous fistula in the neck was admitted with signs of cardial incompensation. Her fistula was fed from the right vertebral artery in antegrade as well as retrograde directions. A steal from the intracranial arteries was established. In addition, smaller feeding arteries from the neck were found. She was operated on with ligation of the right vertebral artery proximal to the fistula but the attempted ligation of the artery cranially to the fistula was unsuccessful. She was therefore embolized by the formation of a plug of platinum fiber coils in the upper right vertebral artery. Catheterization was performed from the left vertebral artery via the basilar artery. Persisting minor feeders to the fistula from cervical arteries were embolized in a second session. Finally, surgical extirpation of the fistula was performed together with the operative ligation of a crossover feeding artery from the left vertebral artery. Her heart size, heart rate and blood pressure were successively normalized. (orig.)

A fourth branchial pouch remnant is well known as a pyriform sinus fistula. However, there has been no report of a fistula composed of the complete remnant of the fourth branchial apparatus. We experienced patients with a congenital lower neck cutaneous fistula which was thought to be the skin-side remnant of the fourth branchial cleft. Seven children were referred to our hospital from 2009 to 2015 for the treatment of a cutaneous fistula situated near the sternoclavicular joint. All of them were surgically resected and their pathological characteristics were examined. Clinical charts were retrospectively reviewed. In six cases, the left side was affected. All cutaneous fistulas had a small skin orifice near the sternoclavicular joint and they were situated at the anterior edge of the sternocleidomastoid muscle. Abscess formation was seen in four cases. Surgical resection was performed at the age of 6 months to 9 years. These fistulas ran deep into the subcutaneous tissue and had a blind end. Pathological examination showed that the epithelial layer was mainly composed of a stratified squamous epithelium. In two cases the epithelium was composed of ciliated columnar epithelium. Recurrence has not been observed in any of the cases. The seven cases had a common clinical feature and were a definite clinical entity. Judging from the characteristics of our cases and the previous literature, we concluded that this lower neck cutaneous fistula was most likely a congenital skin-side remnant of the fourth branchial cleft.

The objective of this study was to review the outcome of endovascular transcatheter repair of emergent arterioenteric fistulas. Cases of abdominal arterioenteric fistulas (defined as a fistula between a major artery and the small intestine or colon, thus not the esophagus or stomach), diagnosed over the 3-year period between December 2002 and December 2005 at our institution, were retrospectively reviewed. Five patients with severe enteric bleeding underwent angiography and endovascular repair. Four presented primary arterioenteric fistulas, and one presented a secondary aortoenteric fistula. All had massive persistent bleeding with hypotension despite volume substitution and transfusion by the time of endovascular management. Outcome after treatment of these patients was investigated for major procedure-related complications, recurrence, reintervention, morbidity, and mortality. Mean follow-up time was 3 months (range, 1-6 months). All massive bleeding was controlled by occlusive balloon catheters. Four fistulas were successfully sealed with stent-grafts, resulting in a technical success rate of 80%. One patient was circulatory stabilized by endovascular management but needed immediate further open surgery. There were no procedure-related major complications. Mean hospital stay after the initial endovascular intervention was 19 days. Rebleeding occurred in four patients (80%) after a free interval of 2 weeks or longer. During the follow-up period three patients needed reintervention. The in-hospital mortality was 20% and the 30-day mortality was 40%. The midterm outcome was poor, due to comorbidities or rebleeding, with a mortality of 80% within 6 months. In conclusion, endovascular repair is an efficient and safe method to stabilize patients with life-threatening bleeding arterioenteric fistulas in the emergent episode. However, in this group of patients with severe comorbidities, the risk of rebleeding is high and further intervention must be considered

To establish the effects of BPC 157 on the healing of rat colovesical fistulas, Wistar Albino male rats were randomly assigned to different groups. BPC 157, a stable gastric pentadecapeptide, has been used in clinical applications-specifically, in ulcerative colitis-and was successful in treating both external and internal fistulas. BPC 157 was provided daily, perorally, in drinking water (10µg/kg, 12ml/rat/day) until sacrifice or, alternatively, 10µg/kg or 10ng/kg intraperitoneally, with the first application at 30min after surgery and the last at 24h before sacrifice. Controls simultaneously received an equivolume of saline (5.0ml/kg ip) or water only (12ml/rat/day). Assessment (i.e., colon and vesical defects, fistula leaking, fecaluria and defecation through the fistula, adhesions and intestinal obstruction as healing processes) took place on days 7, 14 and 28. Control colovesical fistulas regularly exhibited poor healing, with both of the defects persisting; continuous fistula leakage; fecaluria and defecation through the fistula; advanced adhesion formation; and intestinal obstruction. By contrast, BPC 157 given perorally or intraperitoneally and in µg- and ng-regimens rapidly improved the whole presentation, with both colon and vesical defects simultaneously ameliorated and eventually healed. The maximal instilled volume was continuously raised until it reached the values of healthy rats, there were no signs of fecaluria and no defecation through the fistula, there was counteraction of advanced adhesion formation or there was an intestinal obstruction. In conclusion, BPC 157 effects appear to be suited to inducing full healing of colocutaneous fistulas in rats. Copyright © 2016 Elsevier B.V. All rights reserved.

Coronary Arteriovenous Fistula Causing Hydrops Fetalis

Full Text Available Fetal heart failure and hydrops fetalis may occur due to systemic arteriovenous fistula because of increased cardiac output. Arteriovenous fistula of the central nervous system, liver, bone or vascular tumors such as sacrococcygeal teratoma were previously reported to be causes of intrauterine heart failure. However, coronary arteriovenous fistula was not reported as a cause of fetal heart failure previously. It is a rare pathology comprising 0.2–0.4% of all congenital heart diseases even during postnatal life. Some may remain asymptomatic for many years and diagnosed by auscultation of a continuous murmur during a routine examination, while a larger fistulous coronary artery opening to a low pressure cardiac chamber may cause ischemia of the affected myocardial region due to steal phenomenon and may present with cardiomyopathy or congestive heart failure during childhood. We herein report a neonate with coronary arteriovenous fistula between the left main coronary artery and the right ventricular apex, who presented with hydrops fetalis during the third trimester of pregnancy.

Full Text Available Bronchial asthma is a prevalent chronic allergic disease of lungs at early ages. A priority  task in allergology  is to search  biological  markers  related  to uncontrolled atopic  bronchial asthma. Cytokines fulfill their distinct function in pathogenesis of atopic  bronchial asthma, participating at the initiation, development and persistence of allergic inflammation in airways, causing different  variations of clinical course of the disease (with  respect  to its acuteness, severity, frequency of exacerbations. The  present  work has studied  indices  of cellular  and  humoral links of immunity, as well as levels of some  pro and  anti-inflammatory cytokines in peripheral blood serum (IL-4, IL-10, IL-2 and TNFα, aiming to determine potential markers of uncontrolled atopic bronchial asthma in children. A group of Caucasian (European children was involved into the research: Cohort 1, moderate atopic  bronchial asthma with controlled course during the last 3 months (n = 59; Cohort 2, severe/moderate-severe atopic bronchial asthma with uncontrolled course of the disease within last 3 months (n = 51,  Cohort 3 – control, practically healthy  children without signs of atopy  (n = 33. All the  children included in the group with atopic  bronchial asthma underwent regular mono/combined basic therapy  at high/ intermediate therapeutic doses.  We performed a comparative analysis  of cell  population indices  reflecting certain cellular  immunity links,  and  determined significantly  lower  levels of CD3+   lymphocytes, as well as decrease in relative  and  absolute  contents of CD4+  and  CD8+  cells in the  cohort with  uncontrolled course of atopic  bronchial asthma, as compared with controlled-course cohort. When  evaluating concentrations  of cytokines in peripheral blood serum of the patients with controlled and uncontrolled atopic  bronchial asthma, we revealed  significantly  higher

The radiocephalic arteriovenous fistula remains the method of choice for haemodialysis access. In order to assess their suitability for fistula formation, the radial arteries and cephalic veins were examined preoperatively by ultrasound colour flow scanner in conjunction with a pulse-generated run-off system. Intraoperative blood flow was measured after construction of the fistulae. Post-operative follow-up was performed at various intervals to monitor the development of the fistulae. Radial artery and cephalic vein diameter less than 1.6 mm was associated with early fistula failure. The intraoperative fistula blood flow did not correlate with the outcome of the operation probably due to vessel spasm from manipulation. However, blood flow velocities measured non-invasively 1 day after the operation were significantly lower in fistulae that failed early compared with those that were adequate for haemodialysis. Most of the increase in fistula diameter and blood flow occur within the first 2 weeks of surgery.

Full Text Available Summary:. An alternative surgical treatment is proposed for closure of tracheocutaneous fistulas. The authors present a new technique for reconstruction of persistent tracheocutaneous fistula resultant from temporary tracheostomy. The single-stage closure under local anesthesia involves a fistulous tract turnover flap with a perforated 0.15 mm polydioxanone plate between the flap and the subcutaneous closure. This article presents 3 cases of persistent tracheocutaneous fistula treated by this method. At follow-up examination after follow-up, no recurrent fistula formation had occurred, and no respiratory deformity was present.

It is very difficult to treat postoperative fistulas of head and neck cancer by irradiation and other preoperative therapy. We reviewed 179 patients with oral cancer, mesopharyngeal and hypopharyngeal cancer underwent reconstruction between 1994 and 2003. Our analysis reveals that the incidence of fistula is 18.4% and exposure dose is predisposing factor for fistula formation. We observed many fistulas in posterior of oral floor and pedicle flap more than free flap. There are 14 patients of surgical repair, we detected pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA) in them. (author)

Congenital cervical salivary duct fistulae are rare entities and can mimic branchial cleft fistulae. Ectopic salivary tissue associated with these pharyngocervical tracts may have malignant potential. We present a case report of a novel surgical approach and review of the literature. A 27-year-old man presented with complaint of drainage from the right side of his neck since early childhood. A tract was found from the posterior tonsillar pillar into the neck and ectopic salivary tissue was found along the tract. A congenital hearing loss was also present. Transoral robotic (TORS)-assisted surgery was used in the management of this patient and allowed excellent visualization of the pharyngeal component of the lesion and a minimally invasive approach. The patient did well with no recurrence. TORS was helpful for management of a congenital salivary fistula and may be helpful for branchial cleft fistulae. These lesions may be associated with the branchio-oto-renal (BOR) syndrome. © 2015 Wiley Periodicals, Inc.

To determine the usefulness of CT for the evaluation of peripheral bronchopleural fistulas. CT scans of 22 patients with persistent air leak, as seen on serial chest PA, and a clinical history, were retrospectively evaluated. We determined the visibility of direct communication between the lung and pleural space, and the frequency and location of this, and if direct communications were not visualized the probable cause. A bronchopleural fistula(n=13) or its probable cause(n=6) was visualized in 19 patients(86%). Direct communications between the lung and pleural space were seen in 13 patients(59%) ; there were six cases of tuberculous empyema, three of tuberculosis, two of necrotizing empyema, one of trauma, and one of postobstructive pneumonitis. In six patients, bronchiectatic change in peripheral lung adjacent to the pleural cavity was noted, and although this was seen as a probable cause of bronchopleural fistula, direct communication was invisible. Bronchopleural fistula or its probable cause was multiple in 18 of 19 patients, involving the upper and lower lobe in eight, the upper in nine, and the lower in two. CT is useful for evaluating the presence of bronchopleural fistula, and its frequency and location, and in patients in whom the fistula is not directly visualized, the cause of this

Background The importance of the role of bronchial arteries is notable in modern days thoracic surgery. The significance of their anastomoses with adjusted structures has not yet been sufficiently rated, especially in cases of haemoptysis, heart-lung transplantations and treatment of aneurysms of the thoracic aorta. The need of a thorough study is more relevant than ever and appropriate laboratory animals are required. Methods We review the literature in order to highlight the ideal experimental animal for the implementation of pilot programs relative to the bronchial circulation. A comparative analysis of the anatomy of the bronchial arterial system in humans along with these of pigs, dogs, rats, and birds, as being the most commonly used laboratory animals, is presented in details. Results The pig has the advantage that the broncho-oesophageal artery usually originates from the aorta as a single vessel, which makes the recognition and dissection of the artery easy to perform. In dogs, there is significant anatomical variation of the origin of the bronchial arteries. In rats, bronchial artery coming from the aorta is a rare event while in birds the pattern of the bronchial artery tree is clearly different from the human analog. Conclusions The pig is anatomically and physiologically suited for experimental studies on the bronchial circulation. The suitable bronchial anatomy and physiology along with the undeniable usefulness of the pig in experimental research and the low maintenance cost make the pig the ideal model for experiments in bronchial circulation.

Full Text Available A vesicovaginal fistula is one of the complications that a gynaecologist is bound to face after oncological operations, especially in postmenopausal women. Over the years there have been introduced many techniques of surgical treatment of this entity, including transabdominal and transvaginal approaches.We present a case of a 46-year-old patient who suffered from urinary leakage via the vagina due to the presence of a vesicovaginal fistula that developed after radical abdominal hysterectomy and subsequent radiotherapy. The decision was made to repair it laparoscopically due to retracted, fibrous and scarred tissue in the vaginal apex that precluded a transvaginal approach. A small cystotomy followed by an excision of fistula borders was performed. After six-month follow-up no recurrence of the disease has been noted.We conclude that laparoscopy is an interesting alternative to traditional approaches that provides comparable results.

Full Text Available Graves′ ophthalmopathy (GO is one of the frequent manifestations of the disorder which is an inflammatory process due to fibroblast infiltration, fibroblast proliferation and accumulation of glycosaminoglycans. Eye irritation, dryness, excessive tearing, visual blurring, diplopia, pain, visual loss, retroorbital discomfort are the symptoms and they can mimic carotid cavernous fistulas. Carotid cavernous fistulas are abnormal communications between the carotid arterial system and the cavernous sinus. The clinical manifestations of GO can mimic the signs of carotid cavernous fistulas. Carotid cavernous fistulas should be considered in the differential diagnosis of the GO patients especially who are not responding to the standard treatment and when there is a unilateral or asymmetric eye involvement. Here we report the second case report with concurrent occurrence of GO and carotid cavernous fistula in the literature.

Artem'eva, E G; Latfullin, I A

2002-01-01

To study bronchial reactivity and sensitivity with consideration of histamine, serotonin and catecholamines concentration in bronchial mucosa in patients with acute bronchitis (AB) as possible criteria of its becoming chronic. Before the treatment 116 patients with verified AB were examined using inhalation provocative tests (IPT) with histamine, serotonin and obsidian in increasing doses. Also, external respiration function was studied. IPT were repeated after the course of treatment. 87 of 116 AB patients exhibited high bronchial sensitivity and reactivity to inhalations of histamine, serotonin, obsidian. In parallel, there was a rise in the levels of histamine and serotonin and a fall in the level of catecholamines in bronchial mucosa (alveolar macrophages, lymphocytes, neutrophils, mast and APUD-cells). Changes in monoamines concentration in bronchial mucosa were relevant to activity of bronchial inflammation and the presence of obstructive syndrome. Persistent bronchial hyperreactivity to inhalations of histamine and obsidian along with high histamine levels and low level of catecholamines in alveolar macrophages, lymphocytes and mucus is a criterion of bronchitis transformation to chronic one.

Gastrojejunocolic fistula after gastrojejunostomy: a case series

2008-06-01

Full Text Available Abstract Introduction Gastrojejunocolic (GJC fistulae represent a significant post-surgical cause of morbidity and mortality. GJC fistulae represent rare post-surgical complications, and most are associated with gastric surgery. In the past, this complication has been under-recognized because a fistula may form years after surgery. Case presentation We describe two cases of gastrojejunocolic fistula in men aged 67 and 60 who both initially presented with watery diarrhea and weight loss. Upper GI studies with small bowel follow-through or barium contrast enema studies allowed a conclusive diagnosis to be made. Both patients underwent one-stage en bloc resection, and their postoperative course was uneventful. Conclusion With surgery, this condition is entirely correctable. Pre-operative nutritional status should be evaluated in patients undergoing corrective surgery, and total parenteral nutrition plays a major role in the provision of bowel rest to allow recovery in malnourished patients.

Purpose: CSF fistulae represent the 4%-8% of complications after a serious encephalocranial trauma in the infant population. The experience in 3 patients using MRI with Spin-Eco T2 and Cine-GRE sequences is presented. Material and method: Three male patients 6, 11 and 13 years old were studied, who presented encephalocranial trauma and the common complication was Diplococcus Pneumoniae meningitis. They were studied in a 0.5 T equipment with FSE T2 multiplanar sequences with 3 mm slice thickness and Cine-GRE also 3 mm in four phases of 16 images each. Results: Multiple fistulas were found in the temporomastoidic region in two patients. In one case MRI showed only one fistula though the cribiform plate of the ethmoid bone. Conclusions: MRI is a highly reliable method for CSF fistula detection in patients with encephalocranial trauma. FSE-T2-weighted images and Cine-GRE are sensitive sequences. (author)

Pancreatico-pleural Fistula: Case Series

2018-01-01

Full Text Available Pancreatico-pleural fistula is a rare but serious complication of acute and chronic pancreatitis. The pleural effusion caused by pancreatico-pleural fistula is usually massive and recurrent. It is predominately left-sided but right-sided and bilateral effusion does occur. We report four cases of pancreatico-pleural fistula admitted to our hospital. Their clinical presentation and management aspects are discussed. Two patients were managed by pancreatic endotherapy and two patients were managed conservatively. All four patients improved symptomatically and were discharged and are on regular follow-up. Most of these patients would be evaluated for their breathlessness and pleural effusion delaying the diagnosis of pancreatic pathology and management. Hence, earlier recognition and prompt treatment would help the patients to recover from their illnesses. Pancreatic pleural fistula diagnosis requires a high index of suspicion in patients presenting with chest symptoms or pleural effusion. Extremely high pleural fluid amylase levels are usual but not universally present. A chest X-ray, pleural fluid analysis, and abdominal imaging (magnetic resonance cholangiopancreatography/magnetic resonance imaging abdomen more useful than contrast-enhanced computed tomography abdomen would clinch the diagnosis. Endoscopic retrograde cholangiopancreatography with stent or sphincterotomy should be considered when pancreatic duct (PD reveals a stricture or when medical management fails in patients with dilated or irregular PD. Surgical intervention may be indicated in patients with complete disruption of PD or multiple strictures.

To study the social integration of women supported in the urology department of the University Hospital of Point G for obstetric urogenital fistula. Prospective study conducted over a period of 13 months from June 2008 to June 2009 in the Department of Urology at the University Hospital of Point G. The study included all patients who have been operated on at least twice for obstetric fistula genitourinary. Records of surgical, medical records and tracking sheets for each patient were the media database. Situation before treatment: before surgical treatment, 76.92% of patients were rejected by their spouses. The family attended the patient in 84.62% of cases. Situation after treatment: after treatment, 90.31% of women with fistula lived in the matrimonial home or family. The resumption of business activity was announced by 11.2% of patients. Among the women, 93.7% participated in housework. The number of patient intervention ranged from two to five. Healing (fistula closed and no sphincter dysfunction) was complete in 50% of cases. Among the women, 11.54% had sphincter dysfunction after closure of the fistula, which makes a total of fistula closed more than 61% after at least two attempts. The urogenital fistulas are not a fatal disease but is a real handicap for women who suffer to conduct a socio-cultural and economic mainstream. Generally excluded from the ongoing operations of the company, these women are more integrated after successful surgical treatment of the fistula. Copyright © 2013 Elsevier Masson SAS.

Full Text Available Benign duodenocolic fistula (DCF, known as a fistula between the duodenum and colon with orwithout cecum of nonmalignant origin, is an unusual complication of different gastrointestinal diseases. Thepresent paper records a case in which the patient presented with chronic diarrhea, abdominal pain, weight lossas well as having a history of gastric ulcer. Most frequently the condition presents with signs ofmalabsorption such as weight loss and diarrhea, but other symptoms include nausea, vomiting (sometimeswith fecal, and abdominal pain. Gastrointestinal inflammatory conditions are the usual causes. The mostcommon ones are perforated duodenal ulcer and Crohn’s disease. Barium enemas are usually diagnostic.Treatment consists of excising the fistula and repairing the duodenal and colonic defects. Closure of thefistula provides quick relief.

Although it has been postulated that inflammatory cells cause the bronchial hyperresponsiveness which is diagnostic of asthma, until recently there has been little direct evidence of such a link. We have recently shown that calcium ionophore-activated human neutrophils and eosinophils can induce a state of human airway hyperresponsiveness in vitro. In this study we have shown that the anti-inflammatory agent nedocromil sodium, 10(-7) M, inhibited the hyperresponsiveness induced by products released from ionophore activated neutrophils but did not inhibit the release of leukotriene B4 from the same cells. Neutrophil-induced bronchial hyperresponsiveness was also inhibited by pre-treatment of the bronchial tissues with a thromboxane A2 and prostaglandin receptor antagonist, GR32191, 10(-7) M. These findings indicate that cyclooxygenase products are involved in bronchial hyperresponsiveness induced by inflammatory cell products in vitro and that their release can be inhibited by nedocromil sodium.

The goal of this study was to estimate the 2-year cumulative thrombosis-free survival of basilic vein transposition (BVT) and brachiocephalic fistulae in children. All children who underwent BVT or brachiocephalic fistula construction at a tertiary care children's hospital from June 2001 to July 2006 were reviewed. Kaplan-Meier analysis, log-rank test, and proportional hazards regression were done. Sixteen children (7 girls) with inadequate forearm veins underwent creation of 18 fistulae (12 BVT, 6 brachiocephalic). Median age was 14 (9-19) years. Mean (+/-SE) operative times for BVT and brachiocephalic fistulae were 3.4 (+/- 0.6) hours and 1.9 (+/-0.4) hours, respectively. The overall 2-year cumulative survival rate was 74% (BVT, 66%; brachiocephalic fistula, 83%). Four fistulae failed (1 brachiocephalic, 3 BVT) and 14 fistulae were censored (5, patent fistula; 4, renal transplantation; 2, unrelated death; 1, elective conversion to peritoneal dialysis; 1, surgical ligation of fistula; 1, lost to follow-up). Of 18 fistulae, 6 underwent additional interventions (4, percutaneous angioplasty; 2, surgical thrombectomy). There were no significant differences in survival times based on fistula type, prior transplant status, age, or operative time. Brachiocephalic and BVT fistulae create reliable hemodialysis access for children who have inadequate forearm veins to allow construction of more distal fistulae.

There have been several reports describing rectovaginal fistula development after bevacizumab treatment, and these fistulas were diagnosed by CT scan or colonoscopy. We report a case of sigmoid-vaginal fistula diagnosed by fistulography. The case is a 53-year-old woman who was treated for chronic myelogenous leukaemia and gynaecological cancers 8 years previously. At 52 years of age, she was diagnosed with colon cancer and had a partial colectomy performed. One year after surgery, colon cancer recurred, and she was treated with anticancer agents, including bevacizumab. During chemotherapy, she complained of a foul smelling discharge from the vagina. Fistulography revealed a sigmoid-vaginal fistula. This is the first report of vaginal fistulography performed on a patient who was treated with bevacizumab. Fistulography may be useful for detecting sigmoid-vaginal fistula. © 2016 John Wiley & Sons Ltd.

The bronchial diameter measured on computed tomography (CT) can be used to guide double-lumen tube (DLT) sizes objectively. The bronchus is known to be measured most accurately in the so-called bronchial CT window. The authors investigated whether using the bronchial window results in the selection of more appropriately sized DLTs than using the other windows. CT image analysis and prospective randomized study. Tertiary hospital. Adults receiving left-sided DLTs. The authors simulated selection of DLT sizes based on the left bronchial diameters measured in the lung (width 1,500 Hounsfield unit [HU] and level -700 HU), bronchial (1,000 HU and -450 HU), and mediastinal (400 HU and 25 HU) CT windows. Furthermore, patients were randomly assigned to undergo imaging with either the bronchial or mediastinal window to guide DLT sizes. Using the underwater seal technique, the authors assessed whether the DLT was appropriately sized, undersized, or oversized for the patient. On 130 CT images, the bronchial diameter (9.9 ± 1.2 mm v 10.5 ± 1.3 mm v 11.7 ± 1.3 mm) and the selected DLT size were different in the lung, bronchial, and mediastinal windows, respectively (p study, oversized tubes were chosen less frequently in the bronchial window than in the mediastinal window (6/110 v 23/111; risk ratio 0.38; 95% CI 0.19-0.79; p = 0.003). No tubes were undersized after measurements in these two windows. The bronchial measurement in the bronchial window guided more appropriately sized DLTs compared with the lung or mediastinal windows.

The surgical management of anal fistulas is still a matter of discussion and no clear recommendations exist. The present study analyses the results of the ligation of the intersphincteric fistula tract (LIFT) technique in treating complex anal fistulas, in particular healing, fecal continence, and recurrence. Between October 2010 and February 2012, a total of 26 consecutive patients underwent LIFT. All patients had a primary complex anal fistula and preoperatively all underwent clinical examination, proctoscopy, transanal ultrasonography/magnetic resonance imaging, and were treated with the LIFT procedure. For the purpose of this study, fistulas were classified as complex if any of the following conditions were present: tract crossing more than 30% of the external sphincter, anterior fistula in a woman, recurrent fistula, or preexisting incontinence. Patient's postoperative complications, healing time, recurrence rate, and postoperative continence were recorded during follow-up. The minimum follow-up was 16 months. Five patients required delayed LIFT after previous seton. There were no surgical complications. Primary healing was achieved in 19 patients (73%). Seven patients (27%) had recurrence presenting between 4 and 8 weeks postoperatively and required further surgical treatment. Two of them (29%) had previous insertion of a seton. No patients reported any incontinence postoperatively and we did not observe postoperative continence worsening. In our experience, LIFT appears easy to perform, is safe with no surgical complication, has no risk of incontinence, and has a low recurrence rate. These results suggest that LIFT as a minimally invasive technique should be routinely considered for patients affected by complex anal fistula. © The Author(s) 2013.

Full Text Available The effi ciency of lung transplantation is considerably limited by the complications associated with the bronchial pathologies. Despite the progress of the treatment methods, bronchial complications are still remaining as an actual problem in the postoperative period with frequency of occurrence from 7 to 29%. However, the bronchial stenosis are the most common bronchial complications after lung transplantation with mortality from 2 to 4%.Aim. To study an experience of our center of bronchial stenosis treatment in lung recipients. Materials and methods. 34 patients underwent lung transplantation from September 2014 to January 2017. 6 (16% of them had a stenosis of lobar or segmental bronchi from 84 to 494 postoperative day. 5 (83% of them have demonstrated multifocal lesions. In all of the cases there was performed an endoscopic bougienage, which involved a balloon dilatation and electrocoagulated incision of granular tissue under X-ray control. After that the patients were administrated by everolimus.Results. Restenosis was formed in 132,0 ± 94,2 postoperative day after primary treatment in all patients. In four cases (67% we used nitinol stent placement under X-ray control. There were no complications. In 3 cases stents were dislocated distally, so we needed to use repeated endoscopic bougienage to replace the stent. Using of everolimus has allowed to decrease the rate of restenosis, but it need future research.Conclusion. Distal bronchial stenosis after lung transplantation can be managed with endoscopic bougienage and stent placement. Adding everolimus has not signifi cantly affected the risk of frequency of restenosis.

Objective: To evaluate the CT features of aorto-right atrial fistula after aortic valve replacement (AVR) or ascending aortic replacement. Methods: Eighty-seven patients with aortic-right atrial fistula underwent CT after operation. The CT features were retrospectively analyzed. Fistula was measured according to maximum width of the shunt. Results: Aorto-right atrial fistula was detected in 87 patients after aortic valve replacement or ascending aortic replacement by CT scan. Among them, 25 patients were diagnosed as mild aorto-right atrial fistula, 47 patients as moderate, and 15 patients as severe. Thirty-seven patients underwent follow-up CT.Among them, 10 patients with mild to moderate aorto-right atrial fistula were considered to have complete regression, 8 patients with mild aorto-right atrial fistula considered to have incomplete regression, 14 patients with mild to moderate aorto-right atrial fistula considered to have stable condition, and 5 patients with moderate aorto-right atrial fistula considered to have progression at the 3-month follow-up. Conclusion: CT is a useful tool for defining aorto-right atrial fistula after AVR or ascending aortic replacement and for evaluating it in follow-up. (authors)

Sonographic diagnosis of vesicouterine fistula.

Park, O-R; Kim, T-S; Kim, H-J

2003-07-01

Vesicouterine fistula is one of the least common types of urogenital fistula, accounting for only 1-4% of all cases. We report a case of vesicouterine fistula after vacuum delivery in a woman with a history of a previous Cesarean section. The 29-year-old woman was hospitalized due to continuous serosanguinous vaginal leakage and hematuria. Transvaginal sonography demonstrated the presence of a fistulous tract between the uterus and the bladder. Cystoscopy demonstrated a small opening in the posterior bladder wall and a cystogram revealed a fistulous tract between the posterior portion of the bladder and the uterine cavity. Since the patient could not tolerate her symptoms, we decided to close the fistulous tract surgically. The fistulous tract was excised and the bladder and uterus were closed primarily. The bladder was drained with a Foley catheter for 12 days and subsequent follow-up of the patient has demonstrated urinary continence. Copyright 2003 ISUOG. Published by John Wiley & Sons, Ltd.

2007-01-01

Thirteen patients with pyriform sinus fistula treated surgically at our department were clinically evaluated. Twelve (92%) fistulae occurred in the left pyriform sinus, and one (8%) in the right. There were a mean of 4 infectious episodes before the final diagnosis. The median age at the first infection was 5 years, and the median age at surgery was 13 years, although there were 2 elderly patients (over 60 years old) in this series. Association with pharyngeal foreign body was suspected in the case with onset at 81 years of age. There was a history of previous surgery for cervical disease in 54% of the patients. The final diagnosis was based on delineation of the fistula by hypopharyngography, although coronal section of CT and MRI were also useful for understanding the morphopathology. The surgical procedure consisted of identification and staining of the fistula under direct hypopharyngoscopy, followed by identification and extirpation of the fistula until the distal end via a cervical approach. There was no recurrence of infections, although resection of the thyroid gland and identification of the recurrent laryngeal nerve were not always performed. The most important surgical principle is considered to be complete disconnection of the lesion from the hypopharynx, and complete identification and extirpation of the fistula by the procedure used at our department is considered to be a useful surgical strategy.

Rectal mucosal advancement flaps (RMAF) and fistula plugs (FP) are techniques used to manage complex anal fistulas. The purpose of this study was to review and compare the results of these methods of repair. A retrospective review of all complex anal fistulas treated by either a RMAF or a FP at Auckland City Hospital from 2004 to 2008. Comparisons were made in terms of successful healing rates, time to failure and the use of magnetic resonance imaging. Overall, 70 operations were performed on 55 patients (55.7% male). The mean age was 44.9 years. Twenty-one patients (30%) had had at least one previous unsuccessful repair. Indications for repair included 57 high cryptoglandular anal (81%), 4 Crohn's anal (6%), 7 rectovaginal (10%), 1 rectourethral (1%) and 1 pouch-vaginal fistula (1%). All patients were followed up with a mean of 4.5 months. Forty-eight RMAFs (69% of total) were performed with 16 successful repairs (33%). Twenty-two FPs (31% of total) were performed with 7 successful repairs (32%, P = 0.9). In failed repairs, there was no difference in terms of mean time to failure (RMAF 4.8 months versus FP 4.1 months, P = 0.62). Magnetic resonance imaging was performed in 21 patients (37%) before the repair. The success rate in these patients was 20%. The results of treatment of complex anal fistulas are disappointing. The choice of operation of either a RMAF or a FP did not alter the poor healing rates of about one third of patients in each group.

Full Text Available The study involved 30 students with severe bronchial asthma and 30 children with moderate to severe course. Patients with severe bronchial asthma revealed a clear tendency to increase the relative content of interleukin 4 in peripheral blood, which indirectly indicates the severity of inflammation in the bronchi. Almost every second child suffering from severe bronchial asthma reported an increase in the concentration of immunoglobulin E (more than 545.3 IU/ml, and the odds ratio was 1.9 (95% CI 1.1–3.4. In the group of patients with severe bronchial asthma, cases of increased skin sensitivity to household allergens were significantly more frequent compared to the second group. Thus, the size of hyperemia over 15.0 mm was recorded in 81.5 % of children of the first group and only in 51.9 % of persons (Pϕ < 0.05 in the second one. Clinical and epidemiological risk and diagnostic value of individual indicators of atopic reactivity were determined to verify the phenotype of severe bronchial asthma.

Most tracheobronchial and parenchymatous congenital abnormalities of the respiratory system are diagnosed in early life. However, some lesions may be initially silent and diagnosed only in adulthood. These cases included congenital abnormalies of the tracheobronchial tract (tracheal and/or bronchial stenosis, bronchogenic cysts, bronchial atresia, oesotracheal fistula, oesobronchial fistula, and tracheal diverticulum), and lung parenchyma itself (pulmonary sequestration, congenital cystic adenomatoïd malformation, lobar emphysema, lobar or lung hypoplasia). To avoid dreadful complications, these rare cases deserve surgical management, and must be known by chest physicians and surgeons. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Full Text Available Objective: To explore the related risk factors for pancreatic fistula after pancreaticoduodenectomy to provide a theoretical evidence for effectively preventing the occurrence of pancreatic fistula. Methods: A total of 100 patients who were admitted in our hospital from January, 2012 to January, 2015 and had performed pancreaticoduodenectomy were included in the study. The related risk factors for developing pancreatic fistula were collected for single factor and Logistic multi-factor analysis. Results: Among the included patients, 16 had pancreatic fistula, and the total occurrence rate was 16% (16/100. The single-factor analysis showed that the upper abdominal operation history, preoperative bilirubin, pancreatic texture, pancreatic duct diameter, intraoperative amount of bleeding, postoperative hemoglobin, and application of somatostatin after operation were the risk factors for developing pancreatic fistula (P<0.05. The multi-factor analysis showed that the upper abdominal operation history, the soft pancreatic texture, small pancreatic duct diameter, and low postoperative hemoglobin were the dependent risk factors for developing pancreatic fistula (OR=4.162, 6.104, 5.613, 4.034, P<0.05. Conclusions: The occurrence of pancreatic fistula after pancreaticoduodenectomy is closely associated with the upper abdominal operation history, the soft pancreatic texture, small pancreatic duct diameter, and low postoperative hemoglobin; therefore, effective measures should be taken to reduce the occurrence of pancreatic fistula according to the patients’ own conditions.

33 abdominal abscesses associated with fistulae in 31 patients were treated by percutaneous drainage. 19 of these patients had had surgery immediately preceding the drainage. In 64% the percutaneous drainage led to a diagnosis of an internal fistula. Additional therapeutic measures, because of the fistula, were necessary in 45% (operation, biliary drainage, repositioning of catheter). The average duration of drainage was 29 days. 77% of those abscesses which could be drained were treated successfully. Mortality in the entire series was 19%. (orig.) [de

2018-03-01

The objective was to determine the contribution of female genital cutting to genital fistula formation in Niger from the case records of a specialist fistula hospital. A retrospective review was undertaken of the records of 360 patients seen at the Danja Fistula Center, Danja, Niger, between March 2014 and September 2016. Pertinent clinical and socio-demographic data were abstracted from the cases identified. A total of 10 fistulas resulting from gurya cutting was obtained: 9 cases of urethral loss and 1 rectovaginal fistula. In none of the cases was genital cutting performed for obstructed labor or as part of ritual coming-of-age ceremonies, but all cutting procedures were considered "therapeutic" within the local cultural context as treatment for dyspareunia, lack of interest in or unwillingness to engage in sexual intercourse, or female behavior that was deemed to be culturally inappropriate by the male spouse, parents, or in-laws. Clinical cure (fistula closed and the patient continent) was obtained in all 10 cases, although 3 women required more than one operation. Gurya cutting is an uncommon, but preventable, cause of genital fistulas in Niger. The socio-cultural context which gives rise to gurya cutting is explored in some detail.

Extrahepatic arteriovenous fistulas involving the gastroduodenal artery and the portal venous system are rare and almost always a late complication of gastric surgery. Secondary portal hypertension and mesenteric ischemia may provoke abdominal pain, upper and lower gastrointestinal hemorrhage, diarrhea, and weight loss. Until recently, surgical excision has been the therapy of choice with excellent results. The authors report a case of gastroduodenal arterioportal fistula with a rare large interpositioned aneurysm in a cardiopulmonary-compromised patient who was considered a non-surgical candidate. The gastroduodenal arterioportal fistula was occluded endovascularly by means of a detachable balloon. A survey of the literature of this rare type of arterioportal fistula is included. (orig.)

2015-02-01

In this study, we aimed to reveal the normal anatomy and variations of the bronchial arterial system and to determine the sex distribution of these variations by retrospectively reviewing the images of patients who underwent thoracal multidetector computed tomographic angiography for various reasons. Multidetector computed tomographic images of a total of 208 patients (151 men; mean age, 59 years) were retrospectively reviewed to assess the normal anatomy and variations of the bronchial arterial system. A total of 531 bronchial arteries (median, 3; minimum, 1; maximum, 5; mean, 2.5) were detected. The number (mean diameter) of the right bronchial arteries were higher than the left bronchial arteries (290 [1.43 mm] and 241 [1.26 mm], respectively; P arteries were higher with men than with women (2.58 [1.45 mm] and 2.47 [1.32 mm], respectively; P artery, and, secondarily (13.46%), the combination of 2 right (1 intercostal-bronchial trunk and 1 bronchial artery) and 1 left bronchial arteries. Seventy-eight ectopic bronchial arteries were detected in 59 cases (28.3%). They most commonly originated from the aortic arch (37.2%), the descending aorta below the level of T6 (35.9%), or the aortic branches (16.7%). The number of right ectopic bronchial arteries was significantly higher than the left ectopic bronchial arteries (50 [64%] vs 28 [36%]; P arteries was statistically higher with men versus women (45 [29.8%] vs 14 [24.6%]; P arteries can vary substantially among individuals. Multidetector computed tomographic angiography enables a detailed road map of the bronchial arterial system to interventional radiologists and thoracic surgeons.

We assessed the ability of visualization of bronchial artery (BA) by using thin-slice axial images of 4-detector multidetector row CT in 65 patients with hemoptysis. In all patients, the origins of BA were well identified with observation of consecutive axial images with 1 mm thickness by paging method and bronchial arterial embolization (BAE) was performed successfully. Thin-slice axial images were considered to be useful to recognize BA and to perform BAE in patients with hemoptysis. (author)

Purpose: We aimed to retrospectively evaluate bronchial and nonbronchial systemic arteries using multi-detector row helical computed tomographic (MDCT) angiography in patients with pulmonary disorders. Materials and Methods: Thirty-nine patients (24 men, 15 women; mean age, 63.4 years; range, 20-82 years) with congenital and acquired pulmonary disorders of the bronchial and nonbronchial systemic arteries underwent multi-detector row helical computed tomographic angiography of the thorax using a 16-detector row scanner. Each of these patients had experienced an episode of hemoptysis. Computed tomographic angiogram data, which included maximum intensity projections, multiplanar reconstruction, and three-dimensional volume-rendered images, were used to retrospectively analyse the characteristics of the bronchial and nonbronchial systemic arteries. Results: We identified a total of 128 bronchial arteries (76 on the right side and 52 on the left) in 39 patients. We detected 42 nonbronchial systemic artery branches, including 19 internal mammary artery branches, 8 subclavian artery branches, 8 inferior phrenic artery branches, 5 intercostal artery branches, 1 thyrocervical trunk branch, and 1 celiac trunk branch. Thirty-five dilated and tortuous nonbronchial systemic arteries entered into the lung parenchyma and extended down to the lesions. Every case, except the one case of sequestration, was associated with pleural thickening where the vascular structures passed through the extrapleural fat. Conclusions: The variations in both the bronchial artery anatomy and the location and type of the nonbronchial arteries were great. Nonbronchial arteries may be a significant source of hemoptysis. MDCT angiography can be used to detect detailed anatomical information about the origins and courses of bronchial and nonbronchial systemic arteries and their pathophysiologic features.

Open liver trauma causing hepatico caval fistula successfully treated by embolization

Directory of Open Access Journals (Sweden)

Zeineb Mzoughi

2017-02-01

Full Text Available Introduction: Traumatic arteriovenous fistula results from a breach of vascular integrity between a vein and an adjacent artery. Hepato caval fistula is a rare entity. Open surgical approaches have increasingly given way to radiological embolization techniques in the treatment of these arteriovenous fistulae, especially in intrahepatic locations. Case report: We report the case of a patient diagnosed with a fistula, from the right branch of the liver artery to the right hepatic vein, developed following an open liver trauma. Successful embolization through the transarterial route was achieved with simple outcomes. Conclusion: The interventional radiology for endovascular management has revolutionized the treatment of hepatic liver traumas. The conservative treatment is henceforth the common approach even if hepatic artery or hepatic veins are involved in case of arteriovenous fistula.

We present the MRI features of a congenital urethroperineal fistula diagnosed in a 12-year-old boy being evaluated after a single urinary tract infection. This diagnosis was initially suggested by voiding cystourethrogram and confirmed by MRI. Imaging revealed an abnormal fluid-filled tract arising from the posterior urethra and tracking to the perineal skin surface that increased in size during micturition. Surgical resection and histopathological evaluation of the abnormal tract confirmed the diagnosis of congenital urethroperineal fistula. MRI played important roles in confirming the diagnosis and assisting surgical planning. (orig.)

Nigeria task force alerts public to fistula hazards.

Science.gov (United States)

1994-01-01

Nigeria's National Task Force on Vesico-vaginal Fistula has published a booklet to draw public attention to the problem of fistulae. The 20-page booklet explains how fistulae happen and what can be done to prevent them. It makes clear that early marriage and early pregnancy are major causes of fistulae that lead to the social rejection of many young women. The booklet tells the story of two girls in a series of color pictures with accompanying text in Hausa and English. One girl is given in marriage to an older man at the age of nine, becomes pregnant before she is fully grown, suffers obstructed labor, is denied obstetric care and is left with a vesico-vaginal fistula. With urine leaking from her bladder through her vagina, she smells constantly of urine and is thrown out of the house by her husband. Her parents also reject her and she is reduced to begging until one day she hears of a hospital where fistulae can be repaired. After the repair she is warned that if she has any more babies they must be delivered in a hospital. The other girl is not given away in marriage but goes to school, graduates from university and marries a man of her choice. She becomes pregnant only when her body is fully developed, attends the antenatal clinic, has an easy labor and safe delivery. full text

Clinical and echocardiographic features of aorto-atrial fistulas

2005-01-01

Full Text Available Abstract Aorto-atrial fistulas (AAF are rare but important pathophysiologic conditions of the aorta and have varied presentations such as acute pulmonary edema, chronic heart failure and incidental detection of the fistula. A variety of mechanisms such as aortic dissection, endocarditis with pseudoaneurysm formation, post surgical scenarios or trauma may precipitate the fistula formation. With increasing survival of patients, particularly following complex aortic reconstructive surgeries and redo valve surgeries, recognition of this complication, its clinical features and echocardiographic diagnosis is important. Since physical exam in this condition may be misleading, echocardiography serves as the cornerstone for diagnosis. The case below illustrates aorto-left atrial fistula formation following redo aortic valve surgery with slowly progressive symptoms of heart failure. A brief review of the existing literature of this entity is presented including emphasis on echocardiographic diagnosis and treatment.

The assessment of airway dimensions in patients with airway disease by using computed tomography (CT) has been limited by the obliquity of bronchi, the ability to identify the bronchial generation, and the limited number of bronchial measurements. The aims of the present study were (i) to analyze cross-sectional bronchial dimensions after automatic orthogonal reconstruction of all visible bronchi on CT images, and (ii) to compare bronchial morphometry between smokers and nonsmokers. CT and pulmonary function tests were performed in 18 males separated into two groups: 9 nonsmokers and 9 smokers. Bronchial wall area (WA) and lumen area (LA) were assessed using dedicated 3D software able to provide accurate cross-sectional measurements of all visible bronchi on CT. WA/LA and WA/(WA+LA) ratios were computed and all parameters were compared between both groups. Smokers demonstrated greater WA, smaller LA, and consequently greater LA/WA and LA/(WA+LA) ratios than nonsmokers. These differences occurred downward starting at the fourth bronchial generation. 3D quantitative CT method is able to demonstrate significant changes in bronchial morphometry related to tobacco consumption.

Objective: To evaluate the difference of internal diameter of bronchial artery in big lung cancer, small lung cancer, and normal lung with multiple slice CT. Methods: MSCT angiographies of 44 patients with lung cancer confirmed by pathology were retrospectively analyzed, and 29 patients were with big lung cancer (≥3 cm) and 15 patients with small lung cancer (<3 cm). Contrast enhanced helical thin slice CT scan was performed in all patients. Three dimensional images of bronchial artery were processed on workstation. The internal diameter of bronchial artery was measured. Results: The diameter of bronchial artery was (1.9±0.4) mm in 15 small lung cancer and (2.5±0.5) mm in 29 big lung cancer, respectively. There was a significant difference in internal diameter of bronchial artery between big and small lung cancer (P<0.05). Conclusion: Bronchial artery in lung cancer is dilated, and the dilation of bronchial artery in big lung cancer is more prominent than in small lung cancer. (authors)

Low rates of arteriovenous fistula (AVF) maturation prevent optimal fistula use for hemodialysis; however, the mechanism of venous remodeling in the fistula environment is not well understood. We hypothesized that the embryonic venous determinant Eph-B4 mediates AVF maturation. In human AVF and a mouse aortocaval fistula model, Eph-B4 protein expression increased in the fistula vein; expression of the arterial determinant Ephrin-B2 also increased. Stimulation of Eph-B-mediated signaling with ...

Background: A well-functioning mature arteriovenous fistula is essential for the maintenance of haemodialysis in patients with chronic renal failure. The Brescia-Cimino arteriovenous fistula has the best survival characteristics and low rate of complications. The most common reason of fistula failure is thrombosis caused by stenosis. Colour Doppler ultrasonography has proven to be effective in the assessment of anatomical vascular features. The majority of studies were done in patients with clinically presumed arteriovenous fistula complications. However, only limited data are available about the well-functioning mature arteriovenous fistulas. The purpose of the present study was to evaluate completely asymptomatic, mature arteriovenous fistulas with colour Doppler ultrasound. Materials and methods: From July 2001 to April 2003, we examined 139 patients with the end-stage renal disease. They were in the range of 19-79 years of age (mean, 46.7 years). The study included only the patients who met the following criteria: (1) no difficulties with haemodialysis (as reported by nurses); (2) normal venous diastolic blood pressure (<150 mmHg) at monthly evaluation; (3) normal urea clearance x time/urea volume of distribution; (4) blood cells count, plasma electrolytes, and liver function at monthly evaluation. The mean fistula age was 26 months (S.D. = 21.9). The mean time of dialysis therapy was 49 months. Thirty-eight percent patients had primary fistulas, 23%-secondary, 11%-third and 11%-fourth, 4%-fifth, 5%-sixth, and 8% patients had more than sixth. Results: There was no correlation between: (1) patient's age and fistula age; (2) patient's age and number of fistulas in one patient; (3) fistula age and number of fistulas in one patient; (4) localization of fistula and fistula age. There was a strong correlation between dialysis therapy period and number of fistulas in one patient. The mean flow volume was 1204.1 ml/min (S.D. = 554). It was significantly higher in the

2003-01-01

Our aim was to confirm the usefulness of magnetic resonance in the evaluation of perianal fistulas, and in conjunction with a thought anatomical review of affected areas. This would allow for the building of a proper surgical plan, which would necessarily differ according to the fistula's complexity. We studied 75 patients with perianal fistulas and performed 81 MR studies by means of axial, sagittal and coronal T1 and T2 sequences. Fistula type, degree, etiology and correlation to surgical findings were all studied. Fifty-five patients underwent surgical treatment, and 26 underwent a more conservative treatment with MR follow-up. Ninety-nine fistulas were observed and classified according to norms set down by St. James University Hospital. Of the 55 cases submitted to surgery, 46 showed concordance between the surgical report and MR, whose sensitivity was 84%. In 9 patients, there was no correlation. In the study of perianal fistulas, it is important to establish both the fistulous tract and relationship to the sphincter complex. MR permits an identification of the sprinter complex and a more precise anatomical localization of the fistulous trajectory. It is also capable of differentiating between fibrosis and abscess. Therefore, MR is an appropriate technique for the study of perianal fistulas and related surgical planning. (Author) 6 refs

Necrotizing fasciitis secondary to enterocutaneous fistula: three case reports.

Gu, Guo-Li; Wang, Lin; Wei, Xue-Ming; Li, Ming; Zhang, Jie

2014-06-28

Necrotizing fasciitis (NF) is an uncommon, rapidly progressive, and potentially fatal infection of the superficial fascia and subcutaneous tissue. NF caused by an enterocutaneous fistula has special clinical characters compared with other types of NF. NF caused by enterocutaneous fistula may have more rapid progress and more severe consequences because of multiple germs infection and corrosion by digestive juices. We treated three cases of NF caused by postoperative enterocutaneous fistula since Jan 2007. We followed empirically the principle of eliminating anaerobic conditions of infection, bypassing or draining digestive juice from the fistula and changing dressings with moist exposed burn therapy impregnated with zinc/silver acetate. These three cases were eventually cured by debridement, antibiotics and wound management.

To focus on both positive and negative aspects of the interaction between asthmatic patients and the social networks, and to highlight the need of a psychological approach in some individuals to integrate pharmacological treatment is the purpose of review. There is evidence that in some asthmatic patients, the excessive use of social networks can induce depression and stress triggering bronchial obstruction, whereas in others their rational use can induce beneficial effects in terms of asthma management. The increasing asthma prevalence in developed countries seen at the end of last century has raised concern for the considerable burden of this disease on society as well as individuals. Bronchial asthma is a disease in which psychological implications play a role in increasing or in reducing the severity of bronchial obstruction. Internet and, in particular, social media are increasingly a part of daily life of both young and adult people, thus allowing virtual relationships with peers sharing similar interests and goals. Although social network users often disclose more about themselves online than they do in person, there might be a risk for adolescents and for sensitive individuals, who can be negatively influenced by an incorrect use. However, although some studies show an increased risk of depression, other observations suggest beneficial effects of social networks by enhancing communication, social connection and self-esteem.

A Case of Pyriform Sinus Fistula Infection with Double Tracts

Directory of Open Access Journals (Sweden)

Masato Shino

2014-01-01

Full Text Available Pyriform sinus fistula is a rare clinical entity and the precise origin remains controversial. The fistula is discovered among patients with acute suppurative thyroiditis or deep neck infection of the left side of the neck and is usually located in the left pyriform sinus. To the best of our knowledge, only a single tract has been reported to be responsible for pyriform sinus fistula infection. We present a case of a 13-year-old female patient with a pyriform sinus fistula that caused a deep infection of the left side of the neck and showed double-tract involvement discovered during surgical resection of the entire fistula. Both tracts arose around the pyriform sinus and terminated at the upper portion of the left lobe of the thyroid.

Aortoduodenal fistula is a rare and life-threatening cause of gastrointestinal hemorrhage. The patient was a 44-year-old woman who repeated intermittent hematemesis and melena after hysterectomy, para-aortic lymph node dissection, and subsequent radiotherapy. Angiography revealed no bleeding point. Upper gastrointestinal endoscopy showed an ulcer at the third portion of the duodenum. Emergency laparotomy revealed an aortoduodenal fistula which was inferred to be caused by radiotherapy because no recurrence of malignancy was detected. After the fistula was closed, the patient repeated hematemesis and anal bleeding. She died of acute hemorrhagic shock, in spite of three operations including axillo-femoral bypass. We propose that radiation might have played a role in the pathogenesis of the aortoduodenal fistula in our case. The new case of primary aortoduodenal fistula following radiotherapy is added to four cases previously reported in the literature. Six cases in which the lesion of the duodenum could be demonstrated by endoscopy, have been reported in Japan. Aortoduodenal fistula should be considered as a probable diagnosis in patients presenting massive gastrointestinal hemorrhage after radiotherapy. Rapid surgical treatments are needed, and operative procedures to be considered include resection of the aorta with aortic stump closure and axillo-femoral bypass. (author)

Objective: To evaluate the efficiency and safety of intraluminal stent as a treatment of malignant obstruction of digestive tract and esophago-bronchial fistula. Methods: In total 71 patients suffered with malignant obstruction or esophago-bronchial fistula were treated with permanent nickel-titanium alloy, partially covered stents. All the procedures were performed under DSA guidance. Inserted via the oral anal access, the stents were placed at the sites of obstructions or the fistulas. Esophagogram or colonogram were done before and post the intervention. The clinical efficiency was assessed by function of swallowing or defecation in follow-up. Results: In 62 patients (96.9%), function of swallowing was restored after the stent was placed in upper digestive tract without drinking triggered coughing. Symptoms were immediately relieved after the stent was placed in sigmoid colon or rectum. Displacement of stents was seen in 2 cases (2.8%); restenosis in 2 (2.8%); hoarse voice was noted in 1 case (1.4%); intense thoracic pain was complained in 2 cases (2.8%); mild pain was noted in 12 cases (16.9%); and massive hemorrhage was complicated in 1 case (1.4%). All complications were successfully controlled after proper treatment. Conclusion: It is an effective, easy and safe method to treat malignant obstruction of digestive tract or esophago-bronchial fistula using partially covered nickel-titanium alloy stent. (authors)

2017-10-01

Gastropleural fistula (GPF) is a serious complication after bariatric surgery. Multiple treatment modalities including pharmacologic, endoscopic, and revisional surgery have been proposed. We present a case of a GPF managed successfully with a laparoendoscopic approach utilizing a fistula plug. A 43-year-old male patient presented with a GPF after a revisional bariatric surgery. A laparoendoscopic approach including lysis of adhesions, identification of the fistula, plugging the fistula with a BioGore A® fistula plug, placement an enteric stent, placement of a feeding tube, and surgical drainage was performed. The multimedia video illustrates the technique used. Postoperatively, upper gastrointestinal (UGI) imaging showed no evidence of leak. The enteric stent was removed after 2 months after verifying complete healing of the fistula. A laparoendoscopic approach to GPF repair with the use of fistula plug is effective, safe, and feasible.

Schulze, B; Ho, Y-H

2015-02-01

Ligation of intersphincteric fistula tract (LIFT) is a relatively new technique in the treatment of complex anorectal fistulas. As it spares the anal sphincter, rates of post-operative incontinence may be lower when compared to conventional treatment. To date, there have not been enough reports of long-term fistula recurrence rates. We performed a long-term follow-up study of 75 patients who underwent LIFT following seton drainage and partial fistulotomy. Only patients with complex cryptogenic anorectal fistulas were included. After seton insertion and partial fistulotomy, the tract was reviewed at 4 months for the absence of anorectal sepsis. Patients then underwent LIFT in a day surgery setting. Operative time, complications, recurrences and incontinence were evaluated. Between May 2008 and June 2013, 75 patients [51 men, mean age 49.5 years, standard error of the mean (SEM) 1.4 years] were treated with a LIFT protocol. The mean operating time for LIFT was 13.2 min (SEM 1.5 min). Complications included minor bleeding, superficial wound dehiscence and perianal pain. At a mean follow-up of 14.6 months (SEM 1.7 months), there were nine (12 %) recurrences, diagnosed at a mean 9.2 months (SEM 2.7 months). They were treated with seton insertion followed by LIFT with biomesh or anorectal advancement flap, and there were no subsequent recurrences. Review of preoperative and post-operative continence scores revealed only one (1.3 %) patient with minor incontinence following LIFT. Recurrences were significantly related to fistulas with multiple tracts (p < 0.001). Our results suggest that the protocol of seton insertion and partial fistulotomy followed by LIFT is associated with a low recurrence rate comparing well with published results from studies involving other techniques and protocols for treating anal fistula.

The purpose of this investigation was to compare the response of human cell types (bronchial epithelial cells and fibroblasts and skin fibroblasts) to various DNA damaging agents. Repair of DNA single strand breaks (SSB) induced by 5 krads of X-ray was similar for all cell types; approximately 90% of the DNA SSB were rejoined within one hour. During excision repair of DNA damage from u.v.-radiation, the frequencies of DNA SSB as estimated by the alkaline elution technique, were similar in all cell types. Repair replication as measured by BND cellulose chromatography was also similar in epithelial and fibroblastic cells after u.v.-irradiation. Similar levels of SSB were also observed in epithelial and fibroblastic cells after exposure to chemical carcinogens: 7,12-dimethylbenz[a]anthracene; benzo[a]pyrene diol epoxide (BPDE); or N-methyl-N-nitro-N-nitrosoguanidine. Significant repair replication of BPDE-induced DNA damage was detected in both bronchial epithelial and fibroblastic cells, although the level in fibroblasts was approximately 40% of that in epithelial cells. The pulmonary carcinogen asbestos did not damage DNA. DNA-protein crosslinks induced by formaldehyde were rapidly removed in bronchial cells. Further, epithelial and fibroblastic cells, which were incubated with formaldehyde and the polymerase inhibitor combination of cytosine arabinoside and hydroxyurea, accumulated DNA SSB at approximately equal frequencies. These results should provide a useful background for further investigations of the response of human bronchial cells to various DNA damaging agents

Typhoid fever is an enteric infection caused by Salmonella typhi. In Indonesia, typhoid fever is endemic with high incidence of the disease. In daily practice we frequently have patients with bronchial asthma, and it is becoming worse when these patients get typhoid fever. After oral ingestion, Salmonella typhi invades the the intestine mucosa after conducted by microbial binding to epithelial cells, destroying the microfold cells (M cell) then passed through the lamina propria and detected by dendritic cells (DC) which express a variety of pathogen recognition receptors on the surfaces, including Toll-Like Receptor (TLR). expressed on macrophages and on intestinal epithelial cells inducing degradation of IB, and translocation of NF-B (Nuclear Factor-Kappa Beta). This process initiates the induction of pro-inflammatory gene expression profile adhesion molecules, chemokines, adhesion molecules, and other proteins that induce and perpetuate the inflammation in host cells then will induce acute ant intractable attack of bronchial asthma. The role of typhoid fever in bronchial asthma, especially in persons with acute attack of bronchial asthma, is not well understood. In this article, we will discuss the role of typhoid fever in the bronchial asthma patients which may cause bronchial asthma significantly become more severe even triggering the acute and intractable attack of bronchial asthma. This fact makes an important point, to treat completely the typhoid fever in patients with bronchial asthma.

Fistula formation to the inferior vena cava is a rare complication of aortic aneurysm which is often misdiagnosed clinically. In one hundred of reported arteriocaval fistulae, none was originating from the right common iliac artery. We report a case of ileo-caval fistula due to a iatrogenic pseudoaneurysm. High resolution 3D imaging using breath-hold CT angiography is highly specific in identifying the location, extent of the aortocaval fistula as well as the neighbouring anatomic structures.

Congenital lung malformations are increasingly detected before birth. However, bronchial atresia is rarely identified in utero and not always recognized in neonates. There are two types of atresia: (1) proximal, located at the level of the mainstem or the proximal lobar bronchi, which is extremely rare and usually lethal during pregnancy, causing a tremendous volume increase of the distal involved lung with secondary hypoplasia of the normal lung, and (2) peripheral, located at the segmental/subsegmental bronchial level, which may present as an isolated lesion or as part of a complex congenital malformation. Prenatal findings are mostly nonspecific. Postnatal exams show overinflated lung areas and focal bronchial dilations. The typical fluid-filled bronchoceles are not always observed in neonates but develop progressively in the first months of life. This pictorial essay describes the spectrum of imaging findings of bronchial atresia in fetuses, neonates and infants. (orig.)

Diagnosis and management of pancreaticopleural fistula.

Science.gov (United States)

Tay, Clifton Ming; Chang, Stephen Kin Yong

2013-04-01

Pancreaticopleural fistula is a rare diagnosis requiring a high index of clinical suspicion due to the predominant manifestation of thoracic symptoms. The current literature suggests that confirmation of elevated pleural fluid amylase is the most important diagnostic test. Magnetic resonance cholangiopancreatography is the recommended imaging modality to visualise the fistula, as it is superior to both computed tomography and endoscopic retrograde cholangiopancreatography (ERCP) in delineating the tract within the pancreatic region. It is also less invasive than ERCP. While a trial of medical regimen has traditionally been the first-line treatment, failure would result in higher rates of complications. Hence, it is suggested that management strategies be planned based on pancreatic ductal imaging, with patients having poor chances of spontaneous closure undergoing either endoscopic or surgical intervention. We also briefly describe a case of pancreaticopleural fistula in a patient who was treated using a modified Puestow procedure after failed endoscopic treatment.

To evaluate the characteristics of tracheal and main bronchial diverticula in relation with emphysema. A total of 967 CT images were reconstructed with 1.25 mm axial images over 2 months. The incidence, size, number, and location of the tracheal and main bronchial diverticula were analyzed using 3D medical software (Seoul, Korea). The incidence of emphysema and the relationship between emphysema and the size of the diverticula were analyzed. In total, 50 patients (5.1%) showed tracheal diverticula in the right posterolateral wall. In addition, 51 patients (5.2%) showed 89 (9.4%) main bronchial diverticula in the inferior wall, while 68 (72%) showed diverticula in the left posterolateral wall. Tracheal diverticula (6.4 {+-} 5.0 mm, 1.0 {+-} 0.2) were larger and fewer than the main bronchial diverticula (2.1 {+-} 2.0 mm, 1.8 {+-} 1.6) (p<0.05). Moreover, tracheal diverticula (10.3 {+-} 7.4 mm) with emphysema in 13 patients (26%), were larger than those without emphysema (5.1 {+-} 3.0 mm) (p<0.05). On thin-section MDCT, the rates of incidence for tracheal and main bronchial diverticula are about 5%, respectively. Tracheal diverticula in the right posterolateral wall are smaller and fewer than the main bronchial diverticula, which are located primarily in the inferior wall of the left bronchus. Tracheal diverticula with emphysema are larger than those without emphysema.

The effects of continuous positive airway pressure (CPAP) treatment on the function of the lower airways are poorly understood. One of the methods used to determine the influence of positive pressure breathing on lower airways is the bronchial hyperreactivity test. Some authors report that CPAP increases bronchial hyperreactivity, while others report decreases. To assess the influence of CPAP treatment on bronchial reactivity and the effects of bronchial hyperreactivity on compliance to CPAP treatment. The study group consisted of 101 obstructive sleep apnea syndrome patients (88 men and 13 women) with a mean age of 51 ± 11 years, mean apnea-hypopnea index of 53 ± 20 and mean body mass index of 32.6 ± 5.4. Patients were randomly assigned to a treatment group that received 3 weeks of CPAP therapy (group 1) or to a nontreatment control group (group 2). Pulmonary function tests and the methacholine bronchial provocation test were performed at baseline and 3 weeks later. There were no statistically significant differences between treated and control groups in anthropometry and polysomnography variables. At baseline, bronchial hyperreactivity was found in 6 patients from group 1 and 5 patients from group 2. A significant increase in bronchial reactivity was observed after CPAP treatment. Log PC20M decreased from 1.38 ± 0.30 at baseline to 1.26 ± 0.50 (p bronchial hyperreactivity during CPAP treatment were characterized by significantly lower FEV1, FVC and MEF50 values. CPAP produces statistically significant bronchial hyperreactivity. However, there were no clinical symptoms and it is not necessary to withdraw previous therapies. Copyright © 2009 S.

Enterocutaneous (EC) fistula is an abnormal communication between the gastrointestinal tract and the skin. The majority of EC fistulas result from surgery. Only 15-25% of EC fistulas are spontaneous and they often result from underlying diseases such as Crohn's disease, radiation and chemotherapy. A 62-year old woman who, in 2012, underwent Pylorus-preserving cephalic pancreaticoduodenectomy (PPPD sec. Traverso-Longmire), due to an advanced pancreatic ductal adenocarcinoma (pT3N1M1). After surgery, the patient underwent chemotherapy with folfirinox regimen. In December 2016, as a result of the appearance of metastatic liver lesions and perianastomotic recurrence, the patient underwent second line treatment with Gemcitabine and pab-paclitaxel. After five months from the beginning of this new second line therapy she presented an EC fistula. The fistula of the patient was successfully treated with total parenteral nutrition and with percutaneous injection of cyanoacrylic sealant. The result suggests the advisability of percutaneous injection of sealant devices, such as cyanoacrylate glue; in order to successfully control stable Enterocutaneous fistulas with acceptable morbidity and mortality especially in particular situations, such as, with low output EC fistulas without signs of complications or on patients considered not suitable for surgery, a conservative approach could ensure the control of the fistula. This approach is easy and safe, viable and useful for future trials on the efficacy in conservative treatment of EC fistula.

Radiation enteritis can cause late complications including stenosis, perforation, fistulization, and bleeding, which sometimes necessitate surgical treatment, but a complication of ileocutaneous fistula is rarely reported. In this paper, an excellent result of an operation for ileocutaneous fistula due to radiation enteritis is described. A 68-year-old woman had undergone extended total histerectomy and radiation therapy on uterine cervical cancer. After the operation and the radiation therapy, frequent abdominal pain bothered her and then the intestinal fistula ensued resulted in the fistulization. The fistula was located between two stenotic lesions of the intestine caused by radiation enteritis. Resection of ileum including the two stenotic lesion and the fistula and end-to-end anastomosis relieved the symptoms and the treatment course has been satisfactory. The two stenotic lesions were resected because it was suggested that the two stenotic lesions directly led the fistulization. She is now followed asymptomatically. (author).

The radiocephalic arteriovenous fistula remains the method of choice for haemodialysis access. In order to assess their suitability for fistula formation, the radial arteries and cephalic veins were examined preoperatively by ultrasound colour flow scanner in conjunction with a pulse-generated run-off system. Intraoperative blood flow was measured after construction of the fistulae. Post-operative follow-up was performed at various intervals to monitor the development of the fistulae. Radial artery and cephalic vein diameter less than 1.6 mm was associated with early fistula failure. The intraoperative fistula blood flow did not correlate with the outcome of the operation probably due to vessel spasm from manipulation. However, blood flow velocities measured non-invasively 1 day after the operation were significantly lower in fistulae that failed early compared with those that were adequate for haemodialysis. Most of the increase in fistula diameter and blood flow occur within the first 2 weeks of surgery. Copyright © 2011. Published by Elsevier Ltd.

2006-01-01

Objective: To assess the diagnostic value of multi-slice spiral CT virtual bronchoscopy (CTVB) in tracheal and bronchial disease. Methods: Forty-two patients including central lung cancer (n=35), endobronchial tuberculosis (n=3), intrabronchial benign tumor (n=3), and intrabronchial foreign body (n=1) were examined by using multi-slice spiral CT examinations. All the final diagnosis were proved by pathology except 1 patient with endoluminal foreign body was proved by clinic. All patients were scanned on GE Lightspeed 99 scanner, using 10 mm collimation, pitch of 1.35, and reconstructed at 1 mm intervals and 1.25 mm thickness. The chest images of transverse CT and virtual bronchoscopy were viewed by two separate radiologists who were familiar with the tracheal and bronchial anatomy. Results: Among the 42 patients, the tumor of trachea and bronchial lumen appeared as masses in 22 of 35 patients with central lung cancer and bronchial stenosis was found in 13 of 35 patients with central lung cancer, and bronchial wall thickening was revealed on transverse CT in all 35 cases. 3 patients of endobronchial tuberculosis showed bronchial lumen narrowing on CTVB, the bronchial wall thickening was revealed on transverse CT, and the length of the wall thickening was long. 3 patients with intrabronchial benign tumor showed nodules in trachea and bronchial lumen on CTVB, and without wall thickening on transverse CT. CTVB could detect the occlusion of bronchial lumen in 1 patient with intrabronchial foreign body and CTVB was able to visualize the areas beyond stenosis, and the bronchial wall was without thickening on transverse CT. Conclusion: Multi- slice spiral CTVB could reflect the morphology of tracheal and bronchial disease. Combined with transverse CT, it could provide diagnostic reference value for bronchial disease.

2013-09-01

Full Text Available Introduction The standard treatment of colo-vesical fistula is the exeresis of fistula, suture of bladder wall, colic resection with or without temporary colostomy. Usually the approach is open because conversion rates and morbidity are lower than laparoscopy. The aim of video is to show the steps of a new mini-invasive approach of colo-vesical fistula without colic resection. Materials and Methods A 69 years old male underwent laparoscopic conservative treatment of colo-vesical fistula due to endoscopic polipectomy in sigmoid diverticulum. 12 mm trocar for the camera was placed at the umbilicus, two 10 mm trocars were placed along bisiliac line and 5 mm port was placed along left emiclavear line; Trendelenburg position was 20°. The fistulous loop was carefully isolated, clipped with Hem-o-lock® clips and removed. Since diverticular disease appeared slight and no inflammation signs were evident, colon resection was not performed. We sutured and sinked the sigmoid wall; after curettage of the fistula site, the bladder wall was sutured. Fat tissue was placed between sigmoid and bladder wall to reduce the risk of fistula recurrence. Results Operative time, estimated blood loss, catheterization time, time to flatus and hospital stay were respectively 210 minutes, 300 mL, 10 days, 48 h and 8 days. The histological examination showed colonic inflammatory and necrotic tissue. No complications or fistula recurrence occurred at 54 months follow-up. Conclusions The laparoscopic conservative treatment of colo-vesical fistula is a safe and feasible technique, in particular when the diverticular disease is limited and the fistula is not due to diverticulitis.

Full Text Available Abstract Background Maternal outcomes in most countries of the developed world are good. However, in many developing/resource-poor countries, maternal outcomes are bleaker: Every year, more than 500,000 women die in childbirth, mostly in resource-poor countries. Those who survive often suffer from severe and long-term morbidities. One of the most devastating injuries is obstetric fistula, occurring most often in south Asia and sub-Saharan Africa. Fistula treatment and care are available in many countries across Africa and Asia, but there is a lack of reliable data around clinical factors associated with the success of fistula repair surgery. Most published research has been retrospective. While these studies have provided useful information about the care and treatment of fistula, they are limited by the design. This study was designed to identify practices in care that could lead to the design of prospective and randomized controlled trials. Methods Self-administered questionnaires were completed by 40 surgeons known to provide fistula treatment services in Africa and Asia at private and government hospitals. The questionnaire was divided into three parts to address the following issues: prophylactic use of antibiotics before, during, and after fistula surgery; urethral catheter management; and management practices for patients with urinary incontinence following fistula repair. Results The results provide a glimpse into current practices in fistula treatment and care across a wide swath of geographic, economic, and organizational considerations. There is consensus in treatment in some areas (routine use of prophylactic antibiotics, limited bed rest until the catheter is removed, nonsurgical treatment for postsurgical incontinence, while there are wide variations in practice in other areas (duration of catheter use, surgical treatments for postsurgical incontinence.

A gastrosplenic fistula is a rare complication of a gastric or splenic lesion. We report a case of Hodgkin's lymphoma (nodular sclerosis) involving the spleen that was complicated by spontaneous gastrosplenic fistula. The fistula was closed laparoscopically and the patient underwent partial gastrectomy and gastric wall repair followed by successful chemotherapy. This is also the first reported case in published literature where the closure of gastrosplenic fistula and partial gastrectomy was carried out laparoscopically. We recommend that extensive open surgical procedures including total gastroectomy, splenectomy and pancreatectomy may be avoided in the management of gastrosplenic fistula and the patient could be managed by less radical, simple laparoscopic fistulectomy, with partial gastric resection. If the fistula is caused by a malignant process, the surgical repair should be followed by definitive treatment with chemotherapy and radiotherapy. (author)

Coronary artery to left ventricle fistula

Full Text Available Abstract Background Coronary cameral fistulas are an uncommon entity, the etiology of which may be congenital or traumatic. They involve abnormal termination of a coronary artery, usually the right coronary, into a cardiac chamber, usually the right ventricle. Case Presentation We describe a case of female patient with severe aortic stenosis and interventricular septal hypertrophy that underwent bioprosthetic aortic valve replacement with concomitant septal myectomy. On subsequent follow-up an abnormal flow traversing the septum into the left ventricle was identified and Doppler interrogation demonstrated a continuous flow, with a predominantly diastolic component, consistent with coronary arterial flow. Conclusion The literature on coronary cameral fistulas is reviewed and the etiology of the diagnostic findings discussed. In our patient, a coronary artery to left ventricle fistula was the most likely explanation secondary to trauma to the septal perforator artery during myectomy. Since the patient was asymptomatic at the time of diagnosis no intervention was recommended and has done well on follow-up.

Bronchial foreign bodies by children are dangerous and require immediate therapeutic measures. Findings and significance of chest film in the diagnosis of bronchial foreign bodies in 24 children were analysed. All patients were symptomatic. 18 patients had an abnormal and 6 normal auscultation finding. In three cases the physician did not suspect aspiration, and the diagnosis was delayed, which caused the death of one child. Roentgenpositive foreign bodies were found in 8 and -negative in 16 cases. Secondary changes (obstructive emphysema, atelectasis, pneumonia) were seen in 16 cases. In emergency cases the chest films were analysed by physician and later by a radiologist, who found 88% of them to be abnormal. Fluoroscopy of expiratory chest film helps to detect the unilateral emphysema more distinctly. The diagnosis must always be confirmed with bronchoscopy and extraction thereby is the adequate treatment of bronchial bodies. (orig.) [de

We report a case of successful double-lumen endotracheal tube exchange with a soft-tipped extra firm exchange catheter in a patient with severe subcutaneous emphysema. A 70-year-old man underwent right lower lobectomy for primary lung cancer under general anesthesia. He developed pneumothorax on postoperative day (POD) 14, which led to subcutaneous emphysema. An emergent operation was performed on POD20 to close the pulmonary fistula under general anesthesia with a single-lumen endotracheal tube and bronchial blocker. Subcutaneous emphysema became worse and pharyngeal emphysema was also suspected; re-operation to close the pulmonary or bronchial fistula was planned. We decided to place a double-lumen tube to precisely detect the fistula. Under the guide of a Pentax-AWS Airwayscope, the single-lumen endotracheal tube was exchanged uneventfully to a 35 Fr double-lumen endotracheal tube with a 110 cm soft-tipped extra firm exchange catheter. The fistula was detected by a leak test and the operation was performed uneventfully, leading to improvement of subcutaneous emphysema.

Pancreatic Pseudocyst Pleural Fistula in Gallstone Pancreatitis

Directory of Open Access Journals (Sweden)

Sala Abdalla

2016-01-01

Full Text Available Extra-abdominal complications of pancreatitis such as pancreaticopleural fistulae are rare. A pancreaticopleural fistula occurs when inflammation of the pancreas and pancreatic ductal disruption lead to leakage of secretions through a fistulous tract into the thorax. The underlying aetiology in the majority of cases is alcohol-induced chronic pancreatitis. The diagnosis is often delayed given that the majority of patients present with pulmonary symptoms and frequently have large, persistent pleural effusions. The diagnosis is confirmed through imaging and the detection of significantly elevated amylase levels in the pleural exudate. Treatment options include somatostatin analogues, thoracocentesis, endoscopic retrograde cholangiopancreatography (ERCP with pancreatic duct stenting, and surgery. The authors present a case of pancreatic pseudocyst pleural fistula in a woman with gallstone pancreatitis presenting with recurrent pneumonias and bilateral pleural effusions.

Background. To date, bronchial diverticula have generally been treated as a pathological condition associated with chronic obstructive pulmonary disease (COPD), although only a limited amount of published information is available on the relationship between bronchial diverticula as depicted by multidetector computed tomography (MDCT) and airflow limitations. Purpose. To evaluate the relationship between airflow limitations and main bronchial diverticula in the subcarinal region using spirometry and thin-section MDCT. Material and Methods. A total of 189 consecutive adult patients were retrospectively evaluated based on spirometry and thin-section MDCT of the chest. All examinations were performed at our institution between June and October 2008. The study group included 70 women and 119 men with a mean age of 65 years (range 19-86 years). The relationship between the FEV1% and bronchial diverticula in the subcarinal region was analyzed (Student's t-test). Results. The indications for conducting the examinations were pulmonary diseases (82 patients), cardiovascular diseases (22), extrapulmonary malignancies (74), and other conditions (11). A total of 84/189 (44.4%) patients showed bronchial diverticula, and the FEV 1 % of 70/84 (83.3%) patients was above 70. The FEV 1 % of patients with lesions ranged from 26.0 to 97.8 (mean 76.8), whereas the range was 28.1-94.4 (mean 73.7) in those without lesions. There was no significant association between the FEV 1 % and the presence of subcarinal bronchial diverticula (P > 0.05). Conclusion. Our data demonstrate that thin-section chest CT commonly demonstrates main bronchial diverticula in the subcarinal region in patients without airflow limitations. We propose that the presence of a small number of tiny bronchial diverticula under the carina may not be a criterion for the diagnosis of COPD

Biliptysis is an important clinical feature to recognize as it is associated with bronchobiliary fistula, a rare entity. Bronchobiliary fistulas have been diagnosed with planar cholescintigraphy. However, cholescintigraphy with single-photon emission computed tomography (SPECT) can better spatially localize a bronchobiliary fistula as compared to planar cholescintigraphy alone, and is useful for preoperative planning if surgical treatment is required. Here, we present the case of a 23-year-old male who developed a bronchobiliary fistula in the setting of posttraumatic and postsurgical infection, which was diagnosed and localized by cholescintigraphy with SPECT

Advice concerning the early diagnosis of bronchial carcinoma

International Nuclear Information System (INIS)

1982-01-01

Bronchial carcinoma is in the Netherlands for men the most frequent type of cancer; the incidence in women is rising. In the Netherlands nowadays, per year about 7100 persons die of this disease which therefore constitutes an important public health problem. The request of advice asks - among other things - whether in the future the periodical X-ray examination of the thorax for the detection of tuberculosis of persons over 40 years can be continued for presymptomatic cases of bronchial carcinoma. The available relevant literature does not yet give indications that periodical mass radiography has any influence on the morbidity and mortality of the disease. On the other hand, literature describing clinical experience shows that the prognosis of patients with bronchial carcinoma, detected in an early presymptomatic stage, is essentially better than in the case of patients with symptomatic disease. A critical analysis of the literature does not furnish epidemiological arguments to recommend periodical mass radiography for bronchial carcinoma. However, because lungcancer forms an extremely important public health problem and because the scarcity of randomized; controlled studies in this field, the committee advises - from a scientific point of view - to perform such a study in one or preferably two regions in the Netherlands. A number of conditions are mentioned which such a study at least should meet. (Auth.)

To describe the surgical management of second branchial fistulae that extend to the pharynx, specifically to determine whether tonsillectomy, along with surgical excision of the tract affects the rate of recurrence. Retrospective chart review of pediatric patients (agebranchial anomalies at a tertiary-care children's hospital between January 1, 2006 and September 1, 2011. Sinus tracts that extended to the pharynx were considered to be fistulae. Seventy-four patients were identified who underwent surgical excision of 85 total second branchial anomalies - 20 cysts (23.5%), 29 sinuses (34.1%), and 36 fistulae (42.4%). The 36 fistulae were removed from 32 patients, 23 males and 9 females, with an average age of 43.3 months. There were 16 right, 11 left, and 5 bilateral lesions. In 14 (43.8%) of the fistulae cases, a tonsillectomy was performed. There was only one recurrence (2.8%), which occurred 41 months postoperatively. No statistically significant difference for recurrence (p=1.0) was found between the group of patients that underwent tonsillectomy and those that did not. Pediatric branchial anomalies can present as a cyst, sinus, or fistula. They are developmental failures in the involution of the branchial apparatus during the embryologic period. Management of second branchial anomalies is with surgical excision of the tract and ligation of the terminal attachment to the pharynx. Our results suggest that the recurrence rates are not affected by whether or not an ipsilateral tonsillectomy is performed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Obstetric fistula is a debilitating birth injury that affects an estimated 2-3 million women globally, most in sub-Saharan Africa and Asia. The urinary and/or fecal incontinence associated with fistula affects women physically, psychologically and socioeconomically. Surgical management of fistula is available with clinical success rates ranging from 65-95 %. Previous research on fistula repair outcomes has focused primarily on clinical outcomes without considering the broader goal of successful reintegration into family and community. The objectives for this study are to understand the process of family and community reintegration post fistula surgery and develop a measurement tool to assess long-term success of post-surgical family and community reintegration. This study is an exploratory sequential mixed-methods design including a preliminary qualitative component comprising in-depth interviews and focus group discussions to explore reintegration to family and community after fistula surgery. These results will be used to develop a reintegration tool, and the tool will be validated within a small longitudinal cohort (n = 60) that will follow women for 12 months after obstetric fistula surgery. Medical record abstraction will be conducted for patients managed within the fistula unit. Ethical approval for the study has been granted. This study will provide information regarding the success of family and community reintegration among women returning home after obstetric fistula surgery. The clinical and research community can utilize the standardized measurement tool in future studies of this patient population.

TEMS: an alternative method for the repair of benign recto-vaginal fistulae.

Science.gov (United States)

Darwood, R J; Borley, N R

2008-07-01

The repair of high recto-vaginal fistula can be challenging since access may be limited via the endo-anal approach yet the alternative trans-abdominal route carries significant morbidity. We report the use of TEMS to repair a recto-vaginal fistula following anterior resection and pelvic radiotherapy. The patient was placed prone and a 25 cm rectoscope was inserted. A proximally based mucosal advancement flap was raised to repair the fistula. The patient was discharged 2 days later and a contrast study confirmed closure of the fistula. COMPARISON WITH OTHER TECHNIQUES: TEMS allows excellent visualisation of a rectovaginal fistula compared to standard endo-anal or trans-vaginal techniques. The morbidity is lower than the trans-abdominal route. TEMS is a useful technique for the repair of benign recto-vaginal fistula and has distinct advantages over conventional techniques.

Malignant colo-duodenal fistula; case report and review of the literature

Directory of Open Access Journals (Sweden)

2006-12-01

Full Text Available Abstract Background Colo-duodenal fistula is a rare complication of malignant and inflammatory bowel disease. Cases with malignant colo-duodenal fistulae can present with symptoms from the primary, from the fistula or from metastatic disease. The fistula often results in diarrhoea and vomiting with dramatic weight loss. Upper abdominal pain is usually present as is general malaise both from the presence of the disease and from the metabolic sequelae it causes. The diarrhoea relates to colonic bacterial contamination of the upper intestines rather than to a pure mechanical effect. Vomiting may be faeculant or truly faecal and eructation foul smelling but in the case reports this 'classic' symptomatology was often absent despite a fistula being present and patent enough to allow barium through it. Occasionally patients will present with a gastro-intestinal bleed. Case presentation We present an unusual case of colorectal carcinoma, where a 65 year old male patient presented with diarrhoea and vomiting secondary to a malignant colo-duodenal fistula near the hepatic flexure. Adenocarcinoma was confirmed on histology from a biopsy obtained during the patient's oesophageogastroduodenoscopy, and the fistula was demonstrated in his barium enema. Staging computed tomography showed a locally advanced carcinoma of the proximal transverse colon, with a fistula to the duodenum and regional lymphadenopathy. The patient was also found to have subcutaneous metastasis. Following discussions at the multidisciplinary meeting, this patient was referred for palliation, and died within 4 months after discharge from hospital. Conclusion We present the case, discuss the management and review the literature. Colo-duodenal fistulae from colonic primaries are rare but early diagnosis may allow curative surgery. This case emphasises the importance of accurate staging and repeated clinical examination.

Characterization of the upper pouch tracheo-oesophageal fistula in oesophageal atresia.

A small proportion of infants with oesophageal atresia (OA) are thought to have a proximal tracheoesophageal fistula (TOF). Failure to recognize these can hamper mobilization of the upper pouch and lead to life-threatening episodes of aspiration once oral feeding starts. We reviewed our experience of upper pouch fistulae to identify characteristic features of proximal TOF. A retrospective review of TOF/OA patient notes and bronchoscopy photographs and videos, identified from our database from 01/01/2006 to 12/31/2015, was performed. Eight (6.1%) infants were identified (M:F 5:3) from a total population of 131 newly diagnosed TOF/OA infants during the period. Their median gestational age was 33 (range 28-39) weeks, and median birth weight was 1647g (range 1100-3400g). Five were initially diagnosed with pure OA and 3 with a distal TOF. All patients underwent rigid bronchoscopy at the initial surgery but only one proximal fistula was identified. The 7 missed proximal fistulae were subsequently found either during on-table oesophagograms for gap assessment (n=2), at the time of thoracotomy when mobilizing the upper pouch (n=3), or during subsequent bronchoscopy for symptoms post OA repair (n=2). Two patients needed a further operation to divide the fistula. Review of the bronchoscopy videos identified four characteristic differences between upper and lower pouch fistulae. Proximal fistulae are found just distal to the vocal cords, are very small, often no more than a pit, do not open and close with ventilation, and are best identified by insufflation of the esophagus. Upper pouch fistulae are relatively easy to miss because of different characteristics compared with H-type or distal fistulae that have not previously been mentioned in the literature. level IV.

This article offers a risk assessment of bronchial asthma development in children with atopic dermatitis by applying fuzzy-set theory to accumulated statistical data. It is shown that with a view to executing the said task one should exercise a complex approach involving factors such as "IgE level", "existence of obstructions" and "burdened bronchial asthma heredity of immediate relatives". The obtained results will assist in making adequate and well-informed medical decisions as well as facilitate the decrease of the risk of developing bronchial asthma in children with atopic dermatitis.

2010-10-01

Hepatico-portal fistula (HPF) is a rare condition, most often of post-traumatic or iatrogenic origin and occasionally secondary to a ruptured aneurysm of the hepatic artery into the portal vein. HPF in extrahepatic locations often results in portal hypertension (PHT). While Doppler ultrasound, CT angiography, and magnetic resonance angiography are usually demonstrative, arteriography remains indispensable to clarify the exact anatomical configuration. In the treatment of these arteriovenous (AV) fistulas, open surgical approaches have increasingly given way to radiological embolization techniques, especially in intrahepatic locations, but surgery remains indicated for AV fistulas of the hepatic pedicle where maintenance of hepatic arterial flow is a priority of treatment. We report a patient who had an AV fistula of the hepatic pedicle with resultant PHT presenting 5 years after open abdominal trauma. Treatment was surgical; the immediate and long-term postoperative course was uneventful with regression of PHT. Through analysis of this case and a review of the literature, we discuss the clinical, paraclinical, therapeutic, and prognostic features of this lesion. Copyright © 2010.

We report a case of hypopharyngeal fistula which was suspected of being a late complication due to radiotherapy. The patient was 54-year-old female who had undergone total thyroidectomy for thyroid carcinoma in 1967, receiving a total of 75 Gy postoperative irradiation. In 2001 she came to our hospital complaining of neck pain and difficulty in swallowing. On pharyngoesophagogram we found a hypopharyngeal fistula. The fistula was located under the posterior wall of the hypopharynx between C4 and C7. It was undetectable with flexible fiberscope but was detected with rigid endoscope under the general anesthesia. We suspected it was a late complication of the irradiation. We performed endoscopic laser surgery (KTP), resected the tissue between the upper and lower openings of the fistula, and vertically exposed the fistula in the hypopharyngeal space. Her dysphagia improved. We discuss the mechanism of fistula formation in this case. (author)

Eguchipsammia fistula Microsatellite Development and Population Analysis

KAUST Repository

Mughal, Mehreen

2012-12-01

Deep water corals are an understudied yet biologically important and fragile ecosystem under threat from recent increasing temperatures and high carbon dioxide emissions. Using 454 sequencing, we develop 14 new microsatellite markers for the deep water coral Eguchipsammia fistula, collected from the Red Sea but found in deep water coral ecosystems globally. We tested these microsatellite primers on 26 samples of this coral collected from a single population. Results show that these corals are highly clonal within this population stemming from a high level of asexual reproduction. Mitochondrial studies back up microsatellite findings of high levels of genetic similarity. CO1, ND1 and ATP6 mitochondrial sequences of E. fistula and 11 other coral species were used to build phylogenetic trees which grouped E. fistula with shallow water coral Porites rather than deep sea L. Petusa.

The aim of this study was to compare a new MRI method for detecting the existence of cerebrospinal fluid (CSF) fistulae, i. e. MR cisternography, with CT cisternography. In a prospective study, 30 patients with post-traumatic CSF fistulae were examined. The MR examinations were performed with a 1.0-T whole-body MR system, using two T2 * -weighted sequences, a 3D PSIF (time-inversed fast imaging with steady-state precession, FISP) and a 3D constructive interference steady-state (CISS) sequence. The results of MRI and CT cisternography were compared with the surgical findings. The sensitivity in detecting CSF fistulae with MR cisternography (PSIF: 89.9 %; CISS: 93.6 %) was higher than with CT cisternography (72.3 %). The sensitivity of CT cisternography at detecting CSF fistulae in patients with a size of dural lesion less than 2 mm or in patients with multiple dural lesions is significantly lower compared with the MR method. Although the localization of CSF fistulae always proved possible with MR cisternography, this could only be accomplished wih CT in 70 % of cases. The MR cisternography technique is a new examination method with a higher sensitivity for the detection of CSF fistulae than CT cisternography. The CISS technique is superior compared with PSIF and should be used in patients with high-flow CSF fistulas. (orig.)

Kranz, Peter G; Amrhein, Timothy J; Gray, Linda

2017-12-01

The objective of this study is to describe the anatomic and imaging features of CSF venous fistulas, which are a recently reported cause of spontaneous intracranial hypotension (SIH). We retrospectively reviewed the records of patients with SIH caused by CSF venous fistulas who received treatment at our institution. The anatomic details of each fistula were recorded. Attenuation of the veins involved by the fistula was compared with that of adjacent control veins on CT myelography (CTM). Visibility of the CSF venous fistula on CTM and a modified conventional myelography technique we refer to as dynamic myelography was also compared. Twenty-two cases of CSF venous fistula were identified. The fistulas were located between T4 and L1. Ninety percent occurred without a concurrent epidural CSF leak. In most cases (82%), the CSF venous fistula originated from a nerve root sleeve diverticulum. On CTM, the abnormal veins associated with the CSF venous fistula were seen in a paravertebral location in 45% of cases, centrally within the epidural venous plexus in 32%, and lateral to the spine in 23%. Differences in attenuation between the fistula veins and the control veins was highly statistically significant (p CSF venous fistulas are an important cause of SIH that can be detected on both CTM and dynamic myelograph y and may occur without an epidural CSF leak. Familiarity with the imaging characteristics of these lesions is critical to providing appropriate treatment to patients with SIH.

In a previous study a higher than expected prevalence of asthma was found in Lake Munmorah, a coastal town near two power stations, compared with another coastal control town. This study aimed to compare atopy, bronchial hyperreactivity, and reported symptoms of asthma in the power station town and a second control area with greater socioeconomic similarity. A cross sectional survey was undertaken. Lake Munmorah, a coastal town near two power stations, and Dungog, a country town in the Hunter Valley, NSW, Australia. All children attending kindergarten to year 6 at all schools in the two towns were invited to participate in 1990. The response rates for the questionnaire for reported symptoms and associated demographic data were 92% in Lake Munmorah and 93% in Dungog, with 84% and 90% of children respectively being measured for lung function, atopy, and bronchial reactivity. There were 419 boys and 432 girls aged 5 to 12 years. Main outcome measures were current wheeze and bronchial hyper-reactivity, defined as a fall in forced expiratory volume in 1 second (FEV1) or peak expiratory flow (PEF) of 20% or more. Current wheeze was reported in 24.8% of the Lake Munmorah children compared with 14.6% of the Dungog children. Bronchial hyper-reactivity was similar for both groups--25.2% in Lake Munmorah and 22.3% in Dungog. The mean baseline FEV1 was lower in Lake Munmorah than in Dungog (p power station town, but bronchial hyper-reactivity and skin test defined atopy were similar in the two communities. These results are consistent with the previous study and confirm the increased presence of reported symptomatic illness in the town near power stations.

Aortoenteric fistula is a rare but significant clinical entity associated with high morbidity and mortality if remain untreated. Clinical presentation and imaging findings may be subtle and prompt diagnosis can be difficult. Herein, we present a patient who initially presented with abdominal pain and computed tomography showed an aortic aneurysm compressing duodenum without any air bubbles. One month later, the patient presented with gastrointestinal bleeding and computed tomography revealed air bubbles within aneurysm. With a diagnosis of aortoenteric fistula, endovascular aneurysm repair was carried out. This case uniquely presented the computed tomography findings in progression of an aneurysm to an aortoenteric fistula

Helical CT in evaluation of the bronchial tree

Perhomaa, M.; Laehde, S.; Rossi, O.; Suramo, I.

1997-01-01

Purpose: To establish a protocol for and to assess the value of helical CT in the imaging of the bronchial tree. Material and Methods: Noncontrast helical CT was performed in 30 patients undergoing fiberoptic bronchoscopy for different reasons. Different protocols were compared; they included overlapping 10 mm, 5 mm, or 3 mm slices and non-tilted, cephalad or caudal tilted images. Ordinary cross-sectional and multiplanar 2D reformats were applied for visualization of the bronchial branches. The effect of increasing the helical pitch was tested in one patient. Results: A total of 92.1-100% of the segmental bronchi present in the helical acquisitions were identified by the different protocols. The collimation had no significant impact on the identification of the bronchial branches, but utilization of 3-mm overlapping slices made it easier to distinguish the nearby branches and provided better longitudinal visualization of the bronchi in 2D reformats. The tilted scans illustrated the disadvantage of not covering all segmental bronchi in one breath-hold. An increase of the pitch from 1 to 1.5 did not cause noticeable blurring of the images. CT and bronchoscopic findings correlated well in the area accessible to bronchoscopy, but CT detected 5 additional pathological lesions (including 2 cancers) in the peripheral lung. Conclusion: Helical CT supplemented with bronchography-like 2D reformats provides an effective method complementary to bronchoscopy in the examination of the bronchial tree. (orig.)

Full Text Available Antibodies to IgE are a totally new class of medications currently used to enhance the supervision over severe persistent atopic bronchial asthma. Omalizumab is the most well studied, first and only medication of this group, which is recommended for the application and is allowed for treatment of uncontrolled bronchial asthma among adults and children aged 12 and over in different countries of the world, including Russia. High omalizumab assisted treatment costs, as well as the need in the monthly visits to the doctor for the omalizumab injections are justified for the patients, requiring repeat hospitalizations, emergency medical aid, using high doses of the inhalation and/or systemic glucocorticosteroids. The article reviews the criteria for the selection of patients fit for omalizumab assisted treatment.Key words: omalizumab, anti-ige-antibodies, bronchial asthma, allergic rhinitis, treatment, children.

Elevated Shear Stress in Arteriovenous Fistulae: Is There Mechanical Homeostasis?

Science.gov (United States)

McGah, Patrick; Leotta, Daniel; Beach, Kirk; Aliseda, Alberto

2011-11-01

Arteriovenous fistulae are created surgically to provide access for dialysis in patients with renal failure. The current hypothesis is that the rapid remodeling occurring after the fistula creation is in part a process to restore the mechanical stresses to some preferred level (i.e. mechanical homeostasis). Given that nearly 50% of fistulae require an intervention after one year, understanding the altered hemodynamic stress is important in improving clinical outcomes. We perform numerical simulations of four patient-specific models of functioning fistulae reconstructed from 3D Doppler ultrasound scans. Our results show that the vessels are subjected to `normal' shear stresses away from the anastomosis; about 1 Pa in the veins and about 2.5 Pa in the arteries. However, simulations show that part of the anastomoses are consistently subjected to very high shear stress (>10Pa) over the cardiac cycle. These elevated values shear stresses are caused by the transitional flows at the anastomoses including flow separation and quasiperiodic vortex shedding. This suggests that the remodeling process lowers shear stress in the fistula but that it is limited as evidenced by the elevated shear at the anastomoses. This constant insult on the arterialized venous wall may explain the process of late fistula failure in which the dialysis access become occluded after years of use.

Full Text Available Tracheoinnominate artery fistula (TIF is a serious complication of tracheostomy. If untreated, it could be life-threatening. The emergency approach to the condition that includes prompt diagnosis, rapid control of bleeding with a clear airway, and operation with or without interruption of the innominate artery are the most important factors influencing patient outcome. Tracheoesophageal fistula (TEF is another complication of tracheostomy. In association with compromised quality of life, this condition is really hard to be treated. We report a case of combined TIF and TEF in a 27-year-old man with quadriplegia who suffered a car accident but was successfully managed with interruption and ligature of the innominate artery repair of trachea.

To evaluate the immediate and long-term results of arterial embolisation in the management of haemoptysis and to identify factors influencing outcome. A retrospective analysis was carried out of the medical records and angiograms of 50 patients who underwent transarterial embolisation for haemoptysis. The most frequent causes of haemoptysis included bronchiectasis (16%), active tuberculosis (12%) and aspergilloma (12%). A total of 126 bronchial and non-bronchial systemic arteries were embolised in 62 procedures. Immediate cessation of haemoptysis was achieved in 43 patients (86%). Haemoptysis was controlled in 36 patients (72%), recurred in 14 (28%) and 11 (22%) required repeat embolisation. The worst outcomes were observed in patients with aspergilloma: all six suffered recurrent bleeding and three (50%) died from massive haemoptysis. Aspergilloma was also associated with an increased risk of haemoptysis recurrence (p<0.05). A good clinical outcome was achieved in those with active tuberculosis and malignancy. Complication rates were low and included transient chest pain, false aneurysm and one case of lower limb weakness. Bronchial artery embolisation (BAE) is an effective and safe procedure for haemoptysis control in most cases. However, high recurrence and mortality rates are associated with aspergilloma. Early intervention with repeat embolisation is recommended in these patients and elective surgery should be considered. (orig.)

A rare complication of Meckel's diverticulum: A fistula between Meckel's diverticulum and the appendix

Full Text Available Meckel diverticulum is the most common congenital anomaly of the small intestine, occurring in about 2%–4% of the population. Meckel diverticulum results from incomplete closure of the omphalomesenteric duct. The presentation of symptomatic Meckel diverticulum includes gastrointestinal hemorrhage, intestinal obstruction, volvulus, intussusception, diverticulitis, and neoplasms. The development of fistula is an extremely rare complication. Previous literature has even shown an enterocolonic fistula, a vesicodiverticular fistula, ileorectal fistula, and fistula-in-ano. To the best of our knowledge, we present the first case of the fistula complicated between Meckel diverticulum and the appendix in a review of the English literature.

We describe a man with the Marfan syndrome and a prior ascending aortic aneurysm resection who presented with knee pain and concern of endocarditis. Transesophageal echocardiogram showed no vegetations, and computed tomography angiogram of the heart showed a possible pseudoaneurysm. Cardiac catheterization and aortogram revealed the diagnosis of an aorto-right atrial fistula, which was then operatively repaired. This case highlights the role that cardiac catheterization with aortogram can play in the detection of aorto-atrial fistula.

Kiyan, Guersu; Dagli, Tolga E.; Tugtepe, Halil; Kodalli, Nihat

2003-01-01

Congenital H-type and recurrent tracheo-esophageal fistulas (TEF) are always difficult to diagnose. For a more accurate diagnosis we designed a new double balloon catheter, which is a modification of esophageal dilatation balloon. The catheter has two balloons to occlude the esophagus proximal and distal to the fistula. The fistula can be identified by passing of the contrast material to the tracheal tree, which was injected into the esophageal segment between the inflated balloons. To prove the efficiency of this catheter, a TEF was created surgically in a New Zealand rabbit. On the postoperative fourteenth day the catheter was tried and the fistula could be visualized easily by injecting the contrast material. We think this technique may be of use in the diagnosis of TEF in children. (orig.)

Congenital coronary artery fistula is a rare malformation with an incidence of 0.4% of congenital heart disease. Among the various subtypes, fistula to the left ventricle is extremely rare with 6 reported cases till 1983. We present a case of coronary artery fistula between the right coronary artery and the left ventricle. The dilated right coronary artery formed a mass like bulging the right lower heart border in the plain chest PA, we think this is first case with a coronary artery fistula to the left ventricle, reported in Korea

Bronchopleural cutaneous fistula due to Eikenella corrodens.

The aim of this paper is to review the subject and to report on and discuss a case of bronchopleural cutaneous fistula due to Eikenella corrodens. A 16-year-old girl was brought to our hospital with fever and blood-tinged sputum 2 weeks prior to her admission. She suffered from neurologic sequelae of herpetic encephalitis and had been bed-ridden since 5 years of age. A longitudinal paraspinal soft mass had been noted in the previous week by her mother. She had been given oral feeding despite frequent choking for the past few years. On palpation, the mass can be squeezed to follow the least resistance of subcutaneous space longitudinally extending to the lower thoracic region. Chest computed tomography scan revealed right lower lobe necrotizing pneumonitis and a pleuro-cutaneous fistula leading to the subcutaneous air locules. A protracted course of antibiotics was prescribed and subcutaneous air trapping decreased in size over 8 weeks. Eikenella corrodens has increasingly been implicated as a potential causative pathogen in pleuropulmonary infections. Pleuro-cutaneous fistula and abscess formation complicating empyema and necrotizing pneumonitis due to E. corrodens infection have not been reported. A bulging thoracic subcutaneous lesion waxes and wanes with respiration suggest the possibility of a pleruo-cutaneous fistula. Treatment of Eikenella empyema using antibiotics without surgical decortication requires a prolonged course of antibiotic therapy.

Full Text Available Appendico-cutaneous fistulas not related to acute appendicitis or cancer are rare and show spontaneous resolution after conservative treatment, mainly when they show low output, absence of obstruction or sepsis and in patients with good nutritional status. We found no report in the literature on appendico-cutaneous fistula after hysterectomy. The evolution of this case shows that this type of fistula can have low, but persistent debt, requiring definitive surgery. Resumo: Fístulas apendico-cutâneas não relacionadas à apendicite aguda ou neoplasias são raras e de resolução espontânea após tratamento conservador, sobretudo quando se apresentam com baixo débito, ausência de obstrução ou sepse e em pacientes em bom estado nutricional. Não encontramos relato na literatura de fístula apendico-cutânea após histerectomia. A evolução desse caso demonstra que a esse tipo de fístula pode apresentar débito baixo, mas persistente, demandando cirurgia definitiva.

Full Text Available Abstract. We propose a protocol of treatment in cases of bronchial asthma with cytomegalovirus (CMV persistence. This basic therapy is administered depending on the disease severity, according to the National Programme 2009. The treatment includes administration of human immunoglobulin, with dosage according on CMV antibodies titers. The study has revealed that such regimen of antibody administration based on the content of anti-CMV antibodies in bronchial asthma treatment stops active CMV replication in bronchial mucous membrane, alleviates clinical course of the disease, diminishes changes of immune system typical to children suffering from bronchial asthma and CMV reactivation, thus allowing to reduce the volume of basic therapy, along with maintaining control of asthma control.

lower limb ischemia were obtained. Direct measurements of proximal and distal blood pressures in the graft were taken and simultaneous determinations of volume blood flow proximally and distally in the graft with ultrasound transit time technique before and after closure of residual fistulae were made......The objective was to study the intraoperative hemodynamic effects of closure of residual arteriovenous fistulae during in situ saphenous vein graft procedures. Data on 60 residual arteriovenous fistulae in nine patients (five men) with a median age of 74 years (range 64-83 years) with critical....... Closure of a fistula with blood flow around or below 100 mL/min did not increase distal outflow, whereas closure of fistulae with higher blood flow resulted in unpredictable changes in distal outflow. Only fistulae with a blood flow above approximately 100 mL/min may be of hemodynamic significance....

Data concerning the incidence and treatment of pancreatic fistula after necrosectomy in severe acute necrotizing pancreatitis (SAP) are scarce. Our aim was to assess the incidence of pancreatic fistula, and the feasibility and results of endoscopic transpapillary stenting (ETS) in patients with SAP after necrosectomy. From January 2009 to December 2012 twenty-nine consecutive patients with SAP and necrosectomy in Oulu University Hospital were enrolled into this study. Five patients died before ETS because of the rapid progress of the disease and were, therefore, excluded. ERP was performed for the remaining 24 patients demonstrating fistula in 22/24 patients (92 %). ETS was successful in 23 patients and the fistula closed in all of them after a median of 82 (2-210) days with acceptable morbidity and no procedure-related mortality. All patients after necrosectomy for SAP seem to have internal or external pancreatic fistula. EST aimed at internal drainage of the necrosectomy cavity is a feasible and effective therapy in these patients.

The purpose of this study was to analyze the incidence, clinical presentation, diagnosis, and treatment of false traumatic aneurysms and arteriovenous fistulas as well as the outcomes of the patients. A retrospective, 16-year survey has been conducted regarding the cases of patients who underwent surgery for false traumatic aneurysms (FTA) of arteries and traumatic arteriovenous fistulas (TAVF). Patients with iatrogenic AV fistulas and iatrogenic false aneurysms were excluded from the study. There were 36 patients with TAVF and 47 with FTA. In all, 73 (87.95%) were male, and 10 (12.05%) were female, with an average age of 36.93 years (13-82 years). In 25 (29.76%) cases TAVF and FTA appeared combat-related, and 59 (70.24%) were in noncombatants. The average of all intervals between the injury and surgery was 919. 8 days (1 day to 41 years) for FTA and 396.6 days (1 day to 9 years) for TAVF. Most of the patients in both groups were surgically treated during the first 30 days after injury. One patient died on the fourth postoperative day. There were two early complications. The early patency rate was 83.34%, and limb salvage was 100%. There were no recurrent AV fistulas that required additional operations. Because of their history of severe complications, FTA and TAV fistulas require prompt treatment. The treatment is simpler if there is only a short interval between the injury and the operation. Surgical endovascular repair is mostly indicated.

2014-01-01

Full Text Available Arteriovenous fistula (AVF is an anomalous communication between an artery and a vein, caused by an iatrogenic or traumatic etiology. Surgically created upper limb AVF remains the preferred vascular access for patients on maintenance hemodialysis. Nonetheless central vein cannulation for hemodialysis is a common procedure done in patients who need hemodialysis. We incidentally detected a thyrocervical artery - jugular fistula in a patient on maintenance hemodialysis. He underwent a successful intra arterial coil embolization of the feeding vessel. Review of literature has shown that, a thyrocervical artery - internal jugular vein arteriovenous fistula following a central venous catheterization has not been reported so far.

Esophago-pleural fistula (EPF) is an uncommon condition, despite of an anatomical proximity of these structures. Causes of EPF include pneumonectomy for suppurative or tubercular disease of lung and carcinoma lung, malignancy of esophagus. Benign EPF is rare and may be due to trauma or infection. The most common infectious cause is tuberculosis. Spontaneous development of fistula between esophagus and pleura is rarely described in literature. We, hereby present a spontaneous case of such a rare entity in a middle-aged male.

New Surgical Approach for treatment of complex vesicovaginal fistula. Vesical autoplasty; Avances en la cirugia de la fistula vesicovaginal compleja. Autoplastia vesical

2009-07-01

Although currently complex ve sico-vaginal fistulae are an uncommon finding, their solution still remains a problem since no effective surgical technique is yet available. We describe a new vesical autoplasty procedure for solving this entity. Once the fistulae has been thoroughly resected and its borders have been unfolded, a graft is obtained from the posterior-superior vesical wall, which is then slid down to the vesical neck thereby covering great extensions where tissue has been lost, even in the presence of low-capacity bladders. This new operation has led to a 100% cure rate of the 42 consecutive cases of vesico-vaginal fistulae operated on and that had undergone repeated surgery using other thecniques. (Author) 8 refs.

Objective: To investigate the value of treating mediastinoesophageal fistula with covered stent through nasal esophagus drainage tube. Methods: Ten patients with mediastinoesophageal fistula were treated by 5F catheter inserting into the abscess cavities through nasal esophageal fistula, with stent placement in the esophagus. The abscess cavities were washed and angiograghied through drainage tube and the sites of the drainage tube were adjusted in time until withdrawal of the tube. Results: The drainage tubes were pulled out within 10-25 days with disappearance of the abscess cavities and normal diet intake without difficulty. Conclusions: Treating mediastinoesophageal fistula with covered stent through nasal esophagus drainage tube is safe, microinvasive economic and acceptable, worth to be recommended. (authors)

The maintenance of vascular access patency for end-stage renal disease patients on hemodialysis is necessary for survival. Many nephrologists, nurse practitioners, and nurses have limited experience with the physical examination of the arteriovenous fistula. In this review, we define key terms used in the assessment of an arteriovenous fistula. We discuss the arteriovenous fistula physical exam, including details of inspection, palpation, and auscultation. Using these concepts, we review the abnormal findings that can assist practitioners in determining the location of a stenosis. We review the existing literature that validates physical exam findings with gold standard tests such as ultrasound and angiography. Finally, we review data supporting the value of training physicians and nurses in arteriovenous fistula physical examination.

Cervical artery fistulas are rare arteriovenous malformations. The etiology of the vertebral arteriovenous fistulas (AVF) can be traumatic or spontaneous. They tend to be asymptomatic or palpation or continuous vibration in the cervical region. An arteriography is necessary for a definitive diagnosis. The treatment is complete embolization of the fistula. We present the case of a two year-old male, where the mother described it «like a washing machine in his head». On palpation during the physical examination, there was a continuous vibration, and a continuous murmur in left cervical region. A vascular malformation in vertebral region was clinically suspected, and confirmed with angio-MRI and arteriography. AVF are rare in childhood. They should be suspected in the presence of noises, palpation or continuous vibration in the cervical region. Early diagnosis can prevent severe complications in asymptomatic children.

Systemic-pulmonary arteriovenous fistula of traumatic origin: A case report

International Nuclear Information System (INIS)

Hirsch, M.; Maroko, I.; Gueron, M.; Goleman, L.

1983-01-01

Arteriovenous fistulas between the systemic circulation and the pulmonary artery are extremely rare. Continuous precordial murmur is the usual clinical sign while unilateral rib notching may be the only radiologic manifestation of this condition. Selective angiographic investigation is necessary to localize the site of such an arteriovenous (AV) fistula before surgery is performed. In a review of the literature of 15 published cases, the majority were of congenital origin, with four of these systemic-pulmonary AV fistulas of traumatic origin, of which one occurred after insertion of an intercostal catheter. We describe one case of traumatic origin 9 years after percutaneous thoracic drainage for spontaneous pneumothorax, in which transcatheter embolic occlusion of the feeding arteries of an AV fistula was attempted. The advantages and the disadvantages of the non-surgical and surgical therapeutic approaches are discussed. (orig.)

Full Text Available ABSTRACTObstetric fistula (OF is one of the major potential complications of childbirth mostly young women in developing countries including Ethiopia. Though few scientific studies have been conducted related to its causes and consequences, it is challenging to find a comprehensive figure about obstetric fistula in Ethiopia. Therefore, this paper sought that to review the causes and consequences of obstetric fistula in Ethiopia. A number of relevant obstetrics and gynaecology websites and journals were reviewed. Google, Pubmed, and Hinari searching engines were used to find out relevant references. Year of publication, location, language and its type of publication were the inclusion criteria used for reviewing literatures. It is observed that obstetric fistula has been a major burdened mainly for women in the rural Ethiopian and its causes and consequences are very deep and diverse. The great majority of obstetric fistula causes in Ethiopia is due to Obstetric labour. Distance to the health care facility, transportation access, economic factors (poverty, poor knowledge related to the problem, poor health seeking behaviour of the affected women and age at first marriage are the other triggering factors. Stigma and discrimination of obstetric fistula patients by their husbands and families, economic dependency and psychological disorder are often mentioned as consequences for OF patients in Ethiopia.

Hypothalamic digoxin and hemispheric chemical dominance in relation to the pathogenesis of bronchial asthma.

The isoprenoid pathway produces three key metabolites--digoxin (membrane sodium-potassium ATPase inhibitor and regulator of neurotransmitter transport), dolichol (regulator of N-glycosylation of proteins), and ubiquinone (free radical scavenger). The isoprenoid pathway was assessed in patients with bronchial asthma. The pathway was also assessed in patients with right hemispheric, left hemispheric, and bihemispheric dominance to find out the role of hemispheric dominance in the pathogenesis of bronchial asthma. The pathway was upregulated with increase in digoxin synthesis in bronchial asthma. There was an increase in tryptophan catabolites and a reduction in tyrosine catabolites in patients with bronchial asthma. The ubiquinone levels were low and lipid peroxidation increased in these patients. There was increase in dolichol and glycoconjugate levels and reduction in lysosomal stability in these patients. The cholesterol:phospholipid ratio was increased and glycoconjugate levels were reduced in the membranes of these patients. The patterns noticed in bronchial asthma were similar to those in patients with right hemispheric chemical dominance. Bronchial asthma occurs in right hemispheric chemically dominant individuals. Ninety percent of the patients with bronchial asthma were right-handed and left hemispheric dominant by the dichotic listening test. But their biochemical patterns were similar to those obtained in right hemispheric chemical dominance. Hemispheric chemical dominance is a different entity and has no correlation with handedness or the dichotic listening test.

Measurement of the thickness of the bronchial epithelium

Cancer of the lung in uranium miners is thought to be related to the inhalation of gaseous radon daughters which become attached to molecules of water vapour or to dust particles. Since, the depth of tissue penetration by alpha particles is short, the thickness of the epithelium that lines the bronchial tree may be a critical factor in the development of cancers at specific sites in the lung. The objectives of the present study were: 1) to measure the thickness of human bronchial epithelium; 2) to determine the distribution and depth of the nuclei of basal cells in the bronchial epithelium; and 3) to compare these parameters in groups of smokers and non-smokers. Twenty-nine surgically removed specimens of the lung were examined (26 smokers, 3 non-smokers). The specimens were fixed and prepared for examination by light and electron microscopy. Blocks of tissue were oriented so that the maximum number of bronchi were cut in cross-section; measurements included bronchi of all sizes from bronchial generations (1≥ 9.01 mm) diameter to the smallest bronchioles, generations 7 - 16 (0.26 - 2.0 mm). Comparison of measurements in smokers and non-smokers show no significant differences, so that the 29 cases are considered to represent a homogeneous group. With progressive divisions of the bronchi, the epithelium decreases in thickness. Of more importance are the figures relating to the distance from the cell surface to the underlying nucleus. Here too, with the exception of goblet cells, the measurements are significantly smaller in generations 7 - 16 than in generation 1

Objective: To explore DSA findings curative measures and effects of bronchial arterial embolization (BAE)of bronchiectasis with massive hemoptysis. Methods: 35 patients with massive hemoptysis due to bronchiectasis were performed selective bronchial arterial DSA and BAE referring to image data of chest plain film and CT. Embolic materials were polyvinyl alcohol (PVA)and/or gelatinum sponge particles. Curative effects were followed-up for 3 months to 3 years. Results: (1)DSA revealed bronchial artery as being the only abnormal vessel accounted for 74.3%, bronchial artry combined with nonbronchial systemic artery as 22.9% and only non-bronchial artery involved 2.9%. Abnormal vessel number was 1-5 (mean 1.8) per case; Direct and indirect bleeding sign was displayed as 25.7% and 100% respectively. (2)Curative and embolization effects were shown as 61 target vessels of 34 patients being embolized and total effective rate reaching 85.3%; of which 16 cases were adopted super-selective technique, 1 case was failure of stopping bleeding for two times within 3 days, 4 cases recurred within 3 months and 2 cases recurred over 3 months; with recurrent rate of 20.6%, but no serious complications such as spinal cord injury. Conclusions: DSA examination and selective BAE of bronchiectasis with massive hemoptysis could provide high positive angiographic features and reliable curative effect. (authors)

Spontaneous bronchoesophageal fistula in an adult – A possible delayed sequela of pulmonary tuberculosis

Directory of Open Access Journals (Sweden)

Surendra Patel

2015-01-01

Full Text Available Spontaneous bronchoesophageal fistula in the adult is a rare clinical entity. Most bronchoesophageal fistulae are due to malignancy, prolonged endotracheal intubation or trauma. Granulomatous infections like tuberculosis, HIV and mediastinitis are rare causes of acquired bronchoesophageal fistula. We report a case of a 50 year old man, treated for pulmonary tuberculosis 15 years ago, who developed a spontaneous bronchoesophageal fistula between the mid-esophagus and right main stem bronchus, having no history of malignancy or trauma. Surgical closure of the fistula was done and post operative recovery was uneventful. In this case, the bronchoesophageal fistula probably developed as a delayed sequela of pulmonary tuberculosis as the patient had no active signs of pulmonary tuberculosis clinically or histopathologically.

The management of symptomatic pancreatic fistula after pancreaticoduodenectomy is complex and associated with increased morbidity and mortality. We here report continuous irrigation and drainage of the pancreatic remnant to be a feasible and safe alternative to total pancreatectomy. Between 2005 and 2011, patients were analyzed, in which pancreaticojejunal anastomosis was disconnected because of grade C fistula, and catheters for continuous irrigation and drainage were placed close to the pancreatic remnant. Clinical data were monitored and quality of life was evaluated. A total of 13 of 202 patients undergoing pancreaticoduodenectomy required reoperation due to symptomatic pancreatic fistula. Ninety-day mortality of these patients was 15.3%. Median length of stay on the intensive care unit and total length of stay was 18 d (range 3-45) and 46 d (range 33-96), respectively. Patients with early reoperation (<10 d) had significantly decreased length of stay on the intensive care unit and operation time (P < 0.05). Global health status after a median time of 22 mo (range 6-66) was nearly identical, when compared with that of a healthy control group. Mean follow-up was 44.4 mo (±27.2). Four patients (36.6 %) died during the follow-up period; two patients from tumor recurrence, one patient from pneumonia, and one patient for unknown reasons. Treatment of pancreatic fistula by continuous irrigation and drainage of the preserved pancreatic remnant is a simple and feasible alternative to total pancreatectomy. This technique maintains a sufficient endocrine function and is associated with low mortality and reasonable quality of life. Copyright © 2015 Elsevier Inc. All rights reserved.

A 5-year-old boy presented with an infected left-sided branchial fistula. Despite antibiotic treatment and repeated excision of the fistula, purulent discharge from the wound persisted. Three-dimensional computed tomography (3D CT) reconstruction greatly facilitated the diagnosis and management of this case by showing the course of the fistulous tract. The complexity of the tract suggests that this represents a variant arch anomaly because it contains features of first, second, third, and fourth arch remnants. Copyright 2001 by W.B.

Hybrid management of a spontaneous ilio-iliac arteriovenous fistula: a case report

LENUS (Irish Health Repository)

O'Brien, Gavin C

2011-08-22

Abstract Introduction Spontaneous iliac arteriovenous fistulae are a rare clinical entity. Such localized fistulation is usually a result of penetrating traumatic or iatrogenic injury. Clinical presentation can vary greatly but commonly includes back pain, high-output congestive cardiac failure and the presence of an abdominal bruit. Diagnosis, therefore, is often incidental or delayed. Case presentation We report a case of a spontaneous ilio-iliac arteriovenous fistula in a 68-year-old Caucasian man detected following presentation with unilateral claudication and congestive cardiac failure. Following computed tomography evaluation, the fistula was successfully treated with a combined endovascular (aorto-uni-iliac device) and open (femoro-femoral crossover) approach. Conclusion Endovascular surgery has revolutionized the management of such fistulae and we report an interesting case of a high-output iliac arteriovenous fistulae successfully treated with a hybrid vascular approach.

A simple novel technique [PUIT] for closure of urethrocutaneous fistula after hypospadias repair: Preliminary results

Full Text Available Urethrocutaneous fistula is a common complication of urethroplasty for severe hypospadias, even when a microsurgical technique is applied, the closure of the fistula is a challenging problem. We present a simple surgical procedure, posterior urethral incision technique [PUIT] to close the fistula in our department. Between February 2001 and December 2004 we prospectively evaluated 32 patients, 26 patients with initial hypospadias fistulas and 6 with recurrent fistulas who underwent closure of urethrocutaneous fistula after hypospadias repair. The mean age of patients was 5 years, the operation consisted of trimming the fistula edge after mobilization of the skin all-around then a midline posterior urethral incision was done 2 mm above and 2 mm below the fistula opening then re-approximation of the urethral edges using 6/0 vicryl sutures with loop magnification. The timing of fistula repair was between 6 and 13 months after it was formed, all of these were effectively closed except three cases with stricture and fistula. Of these, two were completely relieved after repeated urethral dilatation, three times a week for 2 weeks. The third failed case will need another sitting after 6 months. The posterior midline urethral incision gives a good opportunity for repair without tension with a good cosmetic outcome. This may be done under local anesthesia in adults. The procedure is considered simple rapid and easy to be done for variable fistulas types whatever of its site and the age.

Wall, C. 3rd; Casselbrant, M. L.

1992-01-01

An acute animal model has been developed in the chinchilla for the study of perilymphatic fistulas. Micropunctures were made in three sites to simulate bony, round window, and oval window fistulas. The eye movements in response to pressure applied to the external auditory canal were recorded after micropuncture induction and in preoperative controls. The main pressure stimulus was a pseudorandom binary sequence (PRBS) that rapidly changed between plus and minus 200 mm of water. The PRBS stimulus, with its wide frequency bandwidth, produced responses clearly above the preoperative baseline in 78 percent of the runs. The response was better between 0.5 and 3.3 Hz than it was below 0.5 Hz. The direction of horizontal eye movement was toward the side of the fistula with positive pressure applied in 92 percent of the runs. Vertical eye movements were also observed. The ratio of vertical eye displacement to horizontal eye displacement depended upon the site of the micropuncture induction. Thus, such a ratio measurement may be clinically useful in the noninvasive localization of perilymphatic fistulas in humans.

Rendu-Osler-Weber syndrome presenting with pulmonary arteriovenous fistula

A pulmonary arteriovenous fistula is an abnormal connection between pulmonary arteries and veins. Patients with Rendu-Osler-Weber syndrome may present with this vascular malformation, which is a typical finding of the disease. Approximately 5-15% of Rendu-Osler-Weber syndrome patients have pulmonary arteriovenous malformations (AVM) and there is usually a family history of AVM in these patients. The malformations are usually located in the lower lobes. In this paper, I describe a 49-year-old male patient with dyspnoea, cough, haemoptysis and epistaxis. Physical examination showed nasal telangiectasias, cyanosis of the lips and nails, and a systolic bruit over the left lung. Chest X-ray revealed a 5-cm mass in the left lower lobe and after magnetic resonance examination, together with 3-D magnetic resonance angiography, it was demonstrated to be a pulmonary arteriovenous fistula. The history of a niece with a similar history of suspected pulmonary arteriovenous fistula led me to consider the possibility of Rendu-Osler-Weber syndrome presenting with a pulmonary arteriovenous fistula.

Bronchial artery embolization has been effective in the treatment of massive hemoptysis. The purpose of this study was to report the effectiveness of bronchial artery embolization in patients with chronic recurrent hemoptysis intractable to medical treatment. This study included 25 patients who were admitted for treatment of chronic recurrent hemoptysis with bronchial artery embolization. Chronic recurrent hemoptysis was defined as condition in tractable to medical treatment persistently and occurring over two times per two months The target vessels for embolization were selected in consideration of the results of aortography as well as the finding of chest radiography and bronchoscopy. After selective arteriography for embolization by using 5-French Simmons catheter, embolic agents(mainly polyvinyl alcohol(PVA) and additionally gelfoam and coils) were released through the catheter. The results of the embolization were assessed with review of medical records. The cases of the hemoptysis were pulmonary tuberculosis(n=12.48%), bronchiectasis(n=6.24%), aspergilloma(n=3.12%), chronic obstructive pulmonary disease(n=2.8%), chronic bronchitis(n=1.4%) and lung abscess(n=1.4%). Selective embolization was carried out in 49 sites(42 in bronchial artery and 7 in nonbronchial systemic collaterals). Early success rate within 2 months was 96%. After long-term follow up study (6-30 months, average 15 months), complete remission was 72%, partial remission 12% and recurrence 12% respectively. During and after embolization, major complications such as spinal cord injury or bronchial wall necrosis was not found. Minor complications were chest pain, shoulder pain and chilling sense, which were relieved spontaneously within a few days. High success rate and relatively low recurrence with no significant complication were achieved with bronchial artery embolization in the patients complaining of chronic recurrent hemoptysis.

Full Text Available OBJECTIVE To assess the increased diagnostic yield for pulmonary tuberculosis using bronchial washing cultures compared with sputum cultures. METHODS Study conducted with 61 adults in Lima, Peru, from January 2006 to December 2007. The yield of sputum cultures was compared with the yield of acid-fast bacilli smears and cultures of bronchial washing for diagnosing pulmonary tuberculosis in suspected cases of clinical tuberculosis with negative acid fast bacilli sputum smears. RESULTS Twenty seven (95%CI 32;58 of the cases were eventually diagnosed with smear-negative pulmonary tuberculosis. Bronchial washing samples detected 23 (95%CI 72;99 of the smear-negative pulmonary tuberculosis cases compared with 15 (95%CI 37;74 for sputum cultures (p = 0.02. The incremental diagnostic yield of acid fast bacilli smear and culture of bronchial washing specimens over sputum culture was 44% (95%CI 25;65. CONCLUSIONS In function of the epidemiological context and the resources available, bronchoscopy should be deployed as part of a comprehensive work up that optimizes smear-negative pulmonary tuberculosis diagnosis and minimizes risk and costs.

Bronchobiliary fistulae are rare disorders, with inflammatory diseases of the liver, trauma, previous surgery and biliary obstruction being frequent causative factors. Endoscopic or transhepatic biliary drainage has been used successfully to avoid surgical treatment. We describe a case of a bronchobiliary fistula a 78-year-old man with biliary obstruction caused by impacted calculi. Without surgical or endoscopic intervention, fistulae were treated by percutaneous transhepatic biliary drainage and removal of calculi, in conjunction with balloon sphincteroplasty

Harwood, Lori E.; Wilson, Barbara M.; Oudshoorn, Abe

2016-01-01

Background Arteriovenous fistulas (AVFs) are the preferred access for hemodialysis (HD) yet they are underutilized. Cannulation of the fistula is a procedure requiring significant skill development and refinement and if not done well can have negative consequences for patients. The nurses' approach, attitude and skill with cannulation impacts greatly on the patient experience. Complications from miscannulation or an inability to needle fistulas can result in the increased use of central venous catheters. Some nurses remain in a state of a ‘perpetual novice’ resulting in a viscous cycle of negative patient consequences (bruising, pain), further influencing patients' decisions not to pursue a fistula or abandon cannulation. Method This qualitative study used organizational development theory (appreciative inquiry) and research method to determine what attributes/activities contribute to successful cannulation. This can be applied to interventions to promote change and skill development in staff members who have not advanced their proficiency. Eighteen HD nurses who self-identified with performing successful cannulation participated in audio-recorded interviews. The recordings were transcribed verbatim. The data were analyzed using content analysis. Results Four common themes, including patient-centered care, teamwork, opportunity and skill and nurse self-awareness, represented successful fistula cannulation. Successful cannulation is more than a learned technique to correctly insert a needle, but rather represents contextual influences and interplay between the practice environment and personal attributes. Conclusions Practice changes based on these results may improve cannulation, decrease complications and result in better outcomes for patients. Efforts to nurture positive patient experiences around cannulation may influence patient decision-making regarding fistula use. PMID:26985384

Clinical experience has shown that allergic and non-allergic respiratory, metabolic, mental, and cardiovascular disorders sometimes coexist with bronchial asthma. However, no study has been carried out that calculates the chance of manifestation of these disorders with bronchial asthma in Saarland and Rhineland-Palatinate, Germany. Using ICD10 diagnoses from health care institutions, the present study systematically analyzed the co-prevalence and odds ratios of comorbidities in the asthma population in Germany. The odds ratios were adjusted for age and sex for all comorbidities for patients with asthma vs. without asthma. Bronchial asthma was strongly associated with allergic and with a lesser extent to non-allergic comorbidities: OR 7.02 (95%CI:6.83-7.22) for allergic rhinitis; OR 4.98 (95%CI:4.67-5.32) allergic conjunctivitis; OR 2.41 (95%CI:2.33-2.52) atopic dermatitis; OR 2.47 (95%CI:2.16-2.82) food allergy, and OR 1.69 (95%CI:1.61-1.78) drug allergy. Interestingly, increased ORs were found for respiratory diseases: 2.06 (95%CI:1.64-2.58) vocal dysfunction; 1.83 (95%CI:1.74-1.92) pneumonia; 1.78 (95%CI:1.73-1.84) sinusitis; 1.71 (95%CI:1.65-1.78) rhinopharyngitis; 2.55 (95%CI:2.03-3.19) obstructive sleep apnea; 1.42 (95%CI:1.25-1.61) pulmonary embolism, and 3.75 (95%CI:1.64-8.53) bronchopulmonary aspergillosis. Asthmatics also suffer from psychiatric, metabolic, cardiac or other comorbidities. Myocardial infarction (OR 0.86, 95%CI:0.79-0.94) did not coexist with asthma. Based on the calculated chances of manifestation for these comorbidities, especially allergic and respiratory, to a lesser extent also metabolic, cardiovascular, and mental disorders should be taken into consideration in the diagnostic and treatment strategy of bronchial asthma. PREVALENCE OF CO-EXISTING DISEASES IN GERMANY: Patients in Germany with bronchial asthma are highly likely to suffer from co-existing diseases and their treatments should reflect this.

In a retrospective study of 66 PTFE arteriovenous fistulae and 71 BCH arteriovenous fistulae for dialysis access, PTFE had a higher patency rate than BCH at 12 months (62.4 versus 32.5%). PTFE was easier to work with and easier to handle in the face of infection. The lateral upper arm approach to placement of the PTFE graft is desirable in patients who have had multiple previous access procedures because this area is usually free from scarring, is distant from neurovascular structures, and provides a greater length of graft for needle punctures.

Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.

Radioaerosol inhalation imaging (RII) has been used in radionuclide pulmonary studies for the past 20 years. The method is well accepted for assessing regional ventilation because of its usefulness, easy fabrication and simple application system. To evaluate its clinical utility in the study of impaired regional ventilation in bronchial asthma, we obtained and analysed RIIs in 31 patients (16 women and 15 men; age ranging 21-76 years) with typical bronchial asthma at the Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Medical college, from January, 1988 to August, 1989. Scintiscans were obtained with radioaerosol produced by a HARC(Bhabha Atomic Research Center, India) nebulizer with 15 mCi of 99m Tc-phytate. The scanning was performed in anterior, posterior and lateral projections following 5-minute inhalation of radioaerosol on sitting position. The scans were analysed and correlated with the results of pulmonary function study and the findings of chest radiography. Fifteen patients had concomitant lung perfusion image with 99m Tc-MAA. Follow-up scans were obtained in 5 patients after bronchodilator therapy. 1 he patients were divided into (1) attack type (4 patients), (2) resistant type (5 patients), (3) remittent type (10 patients) and (4) bronchitic type (12 patients). Chest radiography showed hyperinflation, altered pulmonary vascularity, thickening of the bronchial wall and accentuation of hasal interstitial markings in 26 of the 31 patients. Chest radiographs were normal in the remaining 5 patients. Regardless of type, the findings of RII were basically the same, and characterized by the deposition of radioaerosol in the central parts or in the main respiratory air ways along with mottled nonsegmental ventilation defects in the periphery. Peripheral parenchymal defects were more extensive than that of expected findings from clinical symptoms, pulmonary function test and chest radiograph. Broomstick sign was present in 1.7 patients

CT examination of a 53-year-old patient with endocarditis and clinical signs of hepatosplenomegaly revealed an atypical vascular morphology in the hilum of the spleen, for which no diagnosis could be established. Angiography indicated the presence of a symptom-free splenoportal fistula, the histological study of which suggested its congenital genesis. The paper describes the morphology, as ascertained by CT, of the splenic vessels characterised by changed haemodynamics due to a hilar splenoportal fistula.

First branchial arch fistula: diagnostic dilemma and improvised surgical management.

Prabhu, Vinod; Ingrams, Duncan

2011-01-01

First branchial cleft anomalies are uncommon, and only sporadic case reports are published in the literature. They account for 1% to 8% of all the branchial abnormalities. The often variable presentation and tract siting of first arch fistulae have led to misdiagnosis. The misdiagnosis results in inappropriate/ineffective treatment and recurrence of the sinus tract. We present a 19-year-old woman who presented to the ENT outpatient department with episodic discharge from a long-standing fistula anterior to the left sternomastoid muscle. This was associated with repeated episodes of ipsilateral tonsillitis. In relation to the history and because of the position of the fistula, a diagnosis of second branchial arch fistula was made. An attempt at excision was unfortunately followed by early recurrence of discharge. At review following the procedure, a defect of the left tympanic membrane in the form of a fibrous band was noted, and a revised diagnosis of first branchial arch sinus was made. Wide surgical excision of the tract with partial parotidectomy was performed. An uneventful postoperative course followed, with no recurrence of symptoms after 24 months of review. We discuss the case, the diagnostic pathway, and the wide local excision technique used for removal of branchial fistulae. Copyright © 2011 Elsevier Inc. All rights reserved.

Transitional Flow in an Arteriovenous Fistula: Effect of Wall Distensibility

McGah, Patrick; Leotta, Daniel; Beach, Kirk; Aliseda, Alberto

2012-11-01

Arteriovenous fistulae are created surgically to provide adequate access for dialysis in patients with end-stage renal disease. Transitional flow and the subsequent pressure and shear stress fluctuations are thought to be causative in the fistula failure. Since 50% of fistulae require surgical intervention before year one, understanding the altered hemodynamic stresses is an important step toward improving clinical outcomes. We perform numerical simulations of a patient-specific model of a functioning fistula reconstructed from 3D ultrasound scans. Rigid wall simulations and fluid-structure interaction simulations using an in-house finite element solver for the wall deformations were performed and compared. In both the rigid and distensible wall cases, transitional flow is computed in fistula as evidenced by aperiodic high frequency velocity and pressure fluctuations. The spectrum of the fluctuations is much more narrow-banded in the distensible case, however, suggesting a partial stabilizing effect by the vessel elasticity. As a result, the distensible wall simulations predict shear stresses that are systematically 10-30% lower than the rigid cases. We propose a possible mechanism for stabilization involving the phase lag in the fluid work needed to deform the vessel wall. Support from an NIDDK R21 - DK08-1823.

Elevated Plasma Level of Leukotrienes in Bronchial Asthma Patients: A Possible Clinical Relevance

Full Text Available Plasma from bronchial asthma patients and healthy controls was investigated for the content of lipoxygenase products. After lipid extraction using SEP-PAK C18 Cartridges, the lipoxygenase products were measured by Enzyme-Immunoassay. Elevated chemotactic B4 was found in plasma from asthmatic patients with mean value (483±75 pmoUL, while the mean value in normal healthy donors was (140± 12.1 pmol/L (M±SE. The levels of spasmogenic cysteinyl containing leukotrienes were also very high in the bronchial asthma patients. Elevations of leukotriene B4 and cysteinyl containing leukotrienes were detected during attacks of bronchial asthma. These results suggest that leukotriene B4 may be important in the pathogenesis of bronchial asthma and confirmed that peptidoleukotrienes playa role as chemical mediators during the asthmatic attack.

Postoperative pancreatic fistula is a potentially life-threatening complication after pancreatoduodenectomy. Evidence for best management is lacking. To evaluate the clinical outcome of patients undergoing catheter drainage compared with relaparotomy as primary treatment for pancreatic fistula after pancreatoduodenectomy. A multicenter, retrospective, propensity-matched cohort study was conducted in 9 centers of the Dutch Pancreatic Cancer Group from January 1, 2005, to September 30, 2013. From a cohort of 2196 consecutive patients who underwent pancreatoduodenectomy, 309 patients with severe pancreatic fistula were included. Propensity score matching (based on sex, age, comorbidity, disease severity, and previous reinterventions) was used to minimize selection bias. Data analysis was performed from January to July 2016. First intervention for pancreatic fistula: catheter drainage or relaparotomy. Primary end point was in-hospital mortality; secondary end points included new-onset organ failure. Of the 309 patients included in the analysis, 209 (67.6%) were men, and mean (SD) age was 64.6 (10.1) years. Overall in-hospital mortality was 17.8% (55 patients): 227 patients (73.5%) underwent primary catheter drainage and 82 patients (26.5%) underwent primary relaparotomy. Primary catheter drainage was successful (ie, survival without relaparotomy) in 175 patients (77.1%). With propensity score matching, 64 patients undergoing primary relaparotomy were matched to 64 patients undergoing primary catheter drainage. Mortality was lower after catheter drainage (14.1% vs 35.9%; P = .007; risk ratio, 0.39; 95% CI, 0.20-0.76). The rate of new-onset single-organ failure (4.7% vs 20.3%; P = .007; risk ratio, 0.15; 95% CI, 0.03-0.60) and new-onset multiple-organ failure (15.6% vs 39.1%; P = .008; risk ratio, 0.40; 95% CI, 0.20-0.77) were also lower after primary catheter drainage. In this propensity-matched cohort, catheter drainage as first intervention for severe

[Can obstructive bronchitis be a risk factor of bronchial asthma in infants and small children?].

Science.gov (United States)

Gasiorowska, Joanna; Czerwionka-Szaflarska, Mieczysława

2009-01-01

One of more frequent reasons for hospitalizations concerning infants and small children are obstructive bronchitis. Great prevalence of bronchial tree obturation during infancy and in small children is a result of anatomical and functional differences of airways and immunological differences that occur in infants and small children. The most frequent cause of bronchial tree obturation is infection induced by viruses, rarely by bacteria. Recurrences of bronchial tree obturation are observed in some patients. Obturation recurrences can be caused by number of diseases that appear during infancy and in small children, for example cystic fibrosis of the pancreas. Also the presence of foreign body in the airways, immotile cilia syndrome, immunological disturbances, innate anomalies of the respiratory system and the circulatory system and bronchial asthma can result in obturation recurrences. Various clinical criteria are established and new markers of allergic inflammation are searched in view of difficulties to diagnose bronchial asthma in the youngest children. There are no unequivocal rules to diagnose bronchial asthma in infants and small children despite these searches.

Obstetric fistula is a serious medical condition which affects women in low income countries. Despite the progress of research on fistula, there is little data on long term follow-up after surgical repair. The objective of this study is to analyse the factors associated with the recurrence of fistula and the outcomes of pregnancy following fistula repair in Guinea. A descriptive longitudinal study design will be used. The study will include women who underwent fistula repair between 2012 and 2015 at 3 fistula repair sites supported by the Fistula Care Project in Guinea (Kissidougou Prefectoral Hospital, Labé Regional Hospital and Jean Paul II Hospital of Conakry). Participants giving an informed consent after a home visit by the Fistula Counsellors will be interviewed for enrolment at least 3 months after hospital discharge The study enrolment period is January 1, 2012 - June 30, 2015. Participants will be followed-up until June 30, 2016 for a maximum follow up period of 48 months. The sample size is estimated at 364 women. The cumulative incidence rates of fistula recurrence and pregnancy post-repair will be calculated using Kaplan-Meier methods and the risk factor analyses will be performed using adjusted Cox regression. The outcomes of pregnancy will be analysed using proportions, the Pearson's Chi Square (χ2) and a logistic regression with associations reported as risk ratios with 95 % confidence intervals. All analyses will be done using STATA version 13 (STATA Corporation, College Station, TX, USA) with a level of significance set at P < 0.05. This study will contribute to improving the prevention and management of obstetric fistula within the community and support advocacy efforts for the social reintegration of fistula patients into their communities. It will also guide policy makers and strategic planning for fistula programs. ClinicalTrials.gov Identifier: NCT02686957 . Registered 12 February 2016 (Retrospectively registered).

The aim was to display variations of right bronchial tree. The bronchial tree images of 238 patients were reconstructed using the postprocessing technique of CT. We revealed four cases rare bronchial branching patterns of right superior lobe. 1 case was referred to as tracheal bronchus. In 1 case, B1 was located in the place of the right superior lobar bronchus and B2 + 3 arose from the right merge of the IB. In 1 case, the right superior lobar bronchus has only two divisions for B1 and B3, and the bronchus B2 arose from the right merge of the IB. In 1 case, B1 branched into four bronchi. We revealed 15 cases of rare bronchial branching patterns of right inferior lobe. In nine cases, the basal trunk bronchus bifurcated into B7 + 8 and B9 + l0. In three cases, B8 branched from the basal trunk bronchus before B7. In two cases, basal trunk bronchus bifurcated into B7 + 8 + 9 and B10. In 1 case, the basal trunk bronchus bifurcated into the common stem of B7 + 10 and B8 + 9. Variations of right bronchial tree were displayed in the present study. This information may have important implications for diagnosis of symptomatic patients and performing certain procedures, including bronchoscopy, endotracheal intubation, and lung resection.

Association of Gene Polymorphisms in Interleukin 6 in Infantile Bronchial Asthma.

The genetic background of bronchial asthma is complex, and it is likely that multiple genes contribute to its development both directly and through gene-gene interactions. Cytokines contribute to different aspects of asthma, as they determine the type, severity and outcomes of asthma pathogenesis. Allergic asthmatics undergoing an asthmatic attack exhibit significantly higher levels of pro-inflammatory cytokines, such as interleukins and chemokines. In recent years, cytokines and their receptors have been shown to be highly polymorphic, and this prompted us to investigate interleukin 6 promoter polymorphisms at position -174G/C (rs1800795) and at -572G/C (rs1800796) in relation to asthma in children. Interleukin 6 promoter polymorphisms were analyzed in bronchial asthma patients and healthy children using polymerase chain reaction-restriction fragment length polymorphism analysis. We observed a significant association between polymorphism at -174G/C and bronchial asthma (OR=3.4, 95% CI: 2.045-5.638, P<.001). Higher associations between polymorphism at IL-6 -174G/C and bronchial asthma were observed in atopic patients (OR=4.1, 95% CI: 2.308-7.280, P<8.10 -7 ). Interleukin 6 polymorphism is associated with bronchial asthma, particularly its atopic phenotype. Expression and secretion of interleukins in asthmatic patients may be affected by genetic polymorphisms, and could have a disease-modifying effect in the asthmatic airway and modify the therapeutic response.

BACKGROUND: The treatment of complex anocutaneous fistulas remains a major therapeutic challenge balancing the risk of incontinence against the chance of permanent closure. OBJECTIVE: The purpose of this study was to investigate the efficacy of a nitinol proctology clip for closure of complex ano...... with those of other noninvasive, sphincter-sparing techniques for high-complex anocutaneous fistulas, with no risk of incontinence. Predictive parameters for fistula healing using this technique remain uncertain. See Video Abstract at http://links.lww.com/DCR/A347....

Fistula-in-ano, or perianal fistula, is a challenging clinical condition for both diagnosis and treatment. Imaging modalities such as fistulography, anal endosonography, perineal sonography, magnetic resonance imaging (MRI), and computed tomography (CT) are available for its evaluation. MRI is considered as the modality of choice for an accurate delineation of the tract in relation to the sphincter complex and for the detection of associated complications. However, its availability and affordability is always an issue. Moreover, the requirement to obtain multiple sequences to depict the fistula in detail is cumbersome and confusing for the clinicians to interpret. The inability to show the fistula in relation to normal anatomical structures in a single image is also a limitation. Multi detector computed tomography fistulography ( MDCTF ) is an underutilized technique for defining perianal fistulas. Acquisition of iso-volumetric data sets with instillation of contrast into the fistula delineates the tract and its components. Post-processing with thin sections allows for a generation of good quality images for presentation in various planes (multi-planar reconstructions) and formats (volume rendered technique, maximum intensity projection). MDCTF demonstrates the type of fistula, its extent, whether it is simple or complex, and shows the site of internal opening and associated complications; all in easy to understand images that can be used by the surgeons. Its capability to represent the entire pathology in relation to normal anatomical structures in few images is a definite advantage. MDCTF can be utilized when MRI is contraindicated or not feasible. This pictorial review shares our initial experience with MDCT fistulography in evaluating fistula-in-ano, demonstrates various components of fistulas, and discusses the types of fistulas according to the standard Parks classification.

Chronic pancreaticocutaneous fistulas can be difficult to treat. This article presents a snare-target technique for draining a nondilated pancreatic duct into the stomach, diverting pancreatic fluid away from the pancreaticocutaneous fistula to allow it to heal. Internal or internal/external transgastric pancreatic duct or fistula drains were placed in six patients. After an average of 4 months of drainage, all six patients experienced resolution of the cutaneous fistula. Two patients developed a pseudocyst but no recurrent fistula after drain removal, and the other four patients had no pseudocyst or fistula after an average 27-month follow-up (range, 6-74 mo).

Full Text Available Abstract Background: Nowadays, an optimal and effective medical surgery remains the gold standard for perianal fistulas. Hereby we reported preliminary results in favor of using Argentum-quartz solution for both primary and recurrent perianal fistulas. Methods: Three patients with intersphincteric and extrasphincteric fistulas were enrolled. Argentum-quartz solution was administrated twice a week for a period of 4 weeks, followed by a pause of 8 days and then another 4 weeks of treatment, totally 16 administrations. After treatment, all patients were monitored for a 4-month follow-up. Results: Complete closures of 2 extrasphincteric fistulas and a partial closure with absence of inflammation and superative phenomena in the intrasphincteric fistula were both manifested. Conclusion: Selective treatment of perianal fistulas with an argentum-quartz solution is safe and effective, and may represent a reliable alternative.

The relationship between obstructive sleep apnea syndrome (OSAS) and bronchial hyperresponsiveness (BHR) is not well known. In this study, we investigated the association between BHR and disease severity in patients with OSAS. Fourty seven (37 male/10 female) OSAS patients admitted with polysomnography enrolled to the study. Histamine bronchial challenge test was performed and body mass index (BMI, kg/m2) was calculated. Presence of BHR was diagnosed as positivity of bronchial provocative test (BPT) (PD values ≤ 16 mg/mL). Patients were questioned with Epworth sleepiness scale (ESS). Histamine bronchial challenge test was positive in 21 of 47 patients. There were significant negative correlations between PD 20 value and AHI (r= -0.47, p= 0.03), BMI (r= -0.45, p= 0.03), and ESS score (r= -0.45, p= 0.03) in the patients with BHR. In addition, AHI (p= 0.03), BMI (p= 0.02), ESS scores (p= 0.03) were higher in patients with BHR (21 patients) than in patients not having BHR (26 patients). Significant negative relation was found between PD 20 value and AHI (b=-0.45, p= 0.03) and significant positive relation was found between presence of BHR and AHI (p= 0.04), BMI (p= 0.03) independently of age and sex in multiple regression analysis. BHR is common in patients with OSAS. As severity of OSAS increased, severity of BHR increased. In addition, obesity may trigger presence of BHR in patients with OSAS.

2009-02-01

Full Text Available Abstract Background Airway narrowing associated with chronic asthma results in the transmission of injurious compressive forces to the bronchial epithelium and promotes the release of pro-inflammatory mediators and the denudation of the bronchial epithelium. While the individual effects of compression or denudation are well characterized, there is no data to elucidate how these cells respond to the application of mechanical compression in the presence of a compromised epithelial layer. Methods Accordingly, differentiated normal human bronchial epithelial cells were exposed to one of four conditions: 1 unperturbed control cells, 2 single scrape wound only, 3 static compression (6 hours of 30 cmH2O, and 4 6 hours of static compression after a scrape wound. Following treatment, wound closure rate was recorded, media was assayed for mediator content and the cytoskeletal network was fluorescently labeled. Results We found that mechanical compression and scrape injury increase TGF-β2 and endothelin-1 secretion, while EGF content in the media is attenuated with both injury modes. The application of compression after a pre-existing scrape wound augmented these observations, and also decreased PGE2 media content. Compression stimulated depolymerization of the actin cytoskeleton and significantly attenuated wound healing. Closure rate was partially restored with the addition of exogenous PGE2, but not EGF. Conclusion Our results suggest that mechanical compression reduces the capacity of the bronchial epithelium to close wounds, and is, in part, mediated by PGE2 and a compromised cytoskeleton.

2017-05-01

Full Text Available Pharynx fistula is a pathological state that can pose serious problems for both physician and patient and can lead up to the death of the patient in complicated cases. The authors describe a series of guidelines for the management of the pharynx fistula regarding the complications of the instrumentation of the upper digestive tract. Most of the cases that are addressed to our clinic can be treated with a conservative approach and a nutrition therapy plan tailored to each case. In selected cases surgery is the method of choice for therapy. The management of the pharynx fistula can be well managed in a multidisciplinary approach using resources from the E.N.T. and H.N.S. department and more important from the ICU department.

The primary importance of magnetic resonance (MR) imaging in evaluating anal fistulas lies in its ability to demonstrate hidden areas of sepsis and secondary extensions in patients with fistula in ano. MR imaging is relatively expensive, so there are many healthcare systems worldwide where access to MR imaging remains restricted. Until recently, computed tomography (CT) has played a limited role in imaging fistula in ano, largely owing to its poor resolution of soft tissue. In this article, the different imaging features of the CT and MRI are compared to demonstrate the relative accuracy of CT fistulography for the preoperative assessment of fistula in ano. CT fistulography and MR imaging have their own advantages for preoperative evaluation of perianal fistula, and can be applied to complement one another when necessary.

Most primary aortoduodenal fistulas occur in the presence of an aortic aneurysm, which can be part of immunoglobulin G4 (IgG4)-related sclerosing disease. We present a case who underwent endovascular grafting of an aortoduodenal fistula associated with a high serum IgG4 level. A 56-year-old male underwent urgent endovascular reconstruction of an aortoduodenal fistula. The patient received antibiotics and other supportive therapy, and the postoperative course was uneventful, however, elevated levels of serum IgG, IgG4 and C-reactive protein were noted, which normalized after the introduction of steroid therapy. Control computed tomography angiography showed no endoleaks. The primary aortoduodenal fistula may have been associated with IgG4-related sclerosing disease as a possible complication of IgG4-related inflammatory aortic aneurysm. Endovascular grafting of a primary aortoduodenal fistula is an effective and minimally invasive alternative to standard surgical repair. PMID:23155348

Most arise as a complication of prostate cancer treatment. Several procedures have been described to repair rectourethral fistulas with varying outcomes. We review the etiology, management, and outcomes of patients with rectourethral fistulas at our institution.Materials and methods: A retrospective review of patients undergoing repair of rectourethral fistulas was undertaken. Data were collected on patient demographics, fistula etiology, operative procedure, fecal and urinary diversion, and clinical outcome. Patients with urinary and/or fecal diversion underwent radiographic evaluation to confirm closure of the fistula prior to reversal of the diversion.Results: Fistula repair was performed on 22 patients from 1999 to 2009. All the patients were male of an average age of 69 years (range: 39–82 years. All patients, except one, had prostate cancer. Fistula formation was associated with radiotherapy in 54.4% of patients, brachytherapy in 36.4% of patients, and with external beam radiation therapy in 18.2% of patients. Other causes included prostatectomy (seven patients, 31.8%, cryotherapy (two patients, 9.1%, and perianal abscess (one patient, 4.5%. Procedures performed for fistula repair included transanal repair (eleven patients, 50%, transperineal repair (five patients, 22.7%, transabdominal repair (three patients, 13.6%, and York–Mason repair (three patients, 13.6%. Fourteen patients (63.6% had urinary diversion. Fecal diversion was performed in 16 (72.7% patients. Five (22.7% patients had had previous attempts at fistula repair. Of the 22 patients treated, repair was successful in 20 patients (91%. The average

Arteriovesical fistulas are extremely rare. Only eleven cases were previously reported in the literature. They can occur iatrogenically, traumatically or spontaneously. We report an unusual case of a 62-year-old woman with arteriovesical fistula that developed fatal hematuria after transurethral electrocoagulation. Computed tomography (CT) and selective angiography revealed a pseudoaneurysm of the right superior vesical artery with arteriovesical fistula formation, which was managed by transarterial embolization. Contrast enhanced CT or CT angiography should be performed when a pulsatile hemorrhage is revealed during cystoscopy. Therapeutic vesical arterial embolization should be considered as a safe and effective procedure for arteriovesical fistulas. Transurethral electrocoagulation may cause severe hematuria for pulsatile bladder bleeding in patients with pelvic vascular malformation.

Full Text Available Continuous positive airways pressure (CPAP is a well known and safe method of treatment patients with obstructive sleep apnoea syndrome (OSAS. The effects of CPAP administration on the upper respiratory tract are known. However its effects on the lower respiratory tract still needs to be determined. Studies on bronchial hyperreactivity in patients treated by CPAP are contradictory. The aim of the study was to assess the influence of a 3-week CPAP treatment in patients with OSAS and to evaluate associations between changes in bronchial reactivity and clinical features of OSAS and lung function tests (LFT. Patients with newly diagnosed OSAS and lack of infection or chronic illness of the respiratory tract or other conditions which could influence bronchial hyperreactivity (BHR were included. Investigations were performed in 101 patients. There were 88 males and 13 females, mean age 51.5±11.2 years and BMI 32.6±5.4 kg·m–2. Qualified patients were randomly divided into 2 groups: 76 patients to CPAP treatment group, 25 control group. Both groups did not differ in anthropometrics features, severity of OSAS and LFT. Metacholine challenge test (MchCT was performed at baseline and repeated after 3 weeks. Analysis of the individual results showed that in 11 patients the MchCT was positive (6 in the CPAP and 5 in the control groups. After 3 weeks in the group of CPAP treated patients an increase of BHR was noted. Log PC20M decreased from 1.38±0.3 to 1.26±0.5 (p<0.05. The number of patients with a positive result in the MchCT increased from 6 to 16 patients. There was no significant change in BHR in the control group. It was found that CPAP treated patients with BHR were older, had less severe OSAS and lower FEV1 (p<0.05. In none of the patients positive result of BHR did no affect compliance to CPAP treatment. Conclusions: CPAP therapy increases bronchial reactivity, but does not affect compliance to treatment.

Full Text Available Background/Aim. There are limited data examining variations in the local expression of inflammatory mediators in anal fistulas where it is anticipated that an improved understanding of the inflammatory milieu might lead to the potential therapeutic option of instillation therapy in complicated cases. The aim of the present study was to examine prolactin receptors (PRLR as inflammatory markers and to correlate their expression with both the complexity of anal fistulas and the likelihood of fistula recurrence. Methods. Microarray was used to screen the differentially expressed gene profile of anal fistula using anal mucosa samples with hemorrhoids with ageand sex-matched patients as controls and then a prospective analysis of 65 patients was conducted with anal fistulas. PRLR immunohistochemistry was performed to define expression in simple, complex and recurrent anal fistula cases. The quantitative image comparison was performed combining staining intensity with cellular distribution in order to create high and low score PRLR immunohistochemical groupings. Results. A differential expression profile of 190 genes was found. PRLR expression was 2.91 times lower in anal fistula compared with control. Sixty-five patients were assessed (35 simple, 30 complex cases. Simple fistulas showed significantly higher PRLR expression than complex cases with recurrent fistulae showing overall lower PRLR expression than de novo cases (p = 0.001. These findings were reflected in measurable integrated optical density for complex and recurrent cases (complex cases, 8.31 ± 4.91 x 104 vs simple cases, 12.30 ± 6.91 x 104; p < 0.01; recurrent cases, 7.21 ± 3.51 x 104 vs primarily healing cases, 8.31 ± 4.91 x 104; p < 0.05. In univariate regression analysis, low PRLR expression correlated with fistula complexity; a significant independent effect maintained in multivariate analysis odds ratio [(OR low to high PRLR expression = 9.52; p = 0.001]. Conclusion. PRLR

As fistula occurring between the stomach and other abdominal internal organs or to the surface of the body is usually encountered as a complication of stomach cancer or colon cancer, peptic ulcer disease, or other variable causes. The most common type of gastric fistula is a gastro-colic fistula that is mainly found as a complication of a gastric carcinoma or of a carcinoma of the transverse colon invading each other. Sometimes, a benign gastric ulcer perforation also can cause a gastro-colic fistula. However, as far as we know, a fistula occurring between the stomach and the umbilicus has not been reported. Here we present a case report of a gastro-umbilical fistula in a young woman that manifested as a umbilical discharge.

An enterovaginal or vesicovaginal fistula is a complication resulting in vaginal discharge of succus, urine, or stool that can lead to significant complications. For low-volume fistulae, tampons or pads may be used. With high-volume fistulae, frequent product change can be painful and unpredictable in terms of efficacy. The psychologic distress is profound. Surgery may not be an option, making symptom control the priority. We report the use of a reusable menstrual silicone vaginal cup placed to divert and contain drainage. The menstrual cup provided significant symptom relief. Drainage is immediately diverted from tissue, unlike with tampon or pad use, which involves longer contact periods with caustic fluids. A system was created by adapting the end of the cup by adding silastic tubing and an external leg bag to provide long-term drainage control. Improvement in quality of life is of primary importance when dealing with fistula drainage. This simple and inexpensive device should be considered in those cases in which the drainage can be diverted as a viable option, especially in those who are symptomatic and awaiting surgical repair or in those for whom surgery cannot be performed.

The purpose of this paper is to describe a unique 'eighth note' deformity of the autogenous radiocephalic fistula for hemodialysis and to retrospectively evaluate the efficacy and safety of its endovascular treatment. Over 3 years, a total of 808 patients and 558 autogenous radiocephalic fistulas were treated for vascular access dysfunction or thrombosis. These included 14 fistulas in 14 patients (9 men, 5 women; mean age, 58.2 ± 2.8 years; range 27-79 years) whose fistulograms before treatment resembled a musical note, the eighth note. Endovascular treatment sought to remodel the deformed vascular access to a classic radiocephalic fistula and increase the number of cannulation sites available for hemodialysis. The technical and clinical success rates were each 92.8% (13/14). Fistula remodeling was successful in 13 patients. The postintervention primary patency was 100% at 90 days, 91.7 ± 0.8% at 120 days, 78.6 ± 13.9% at 180 days, 62.9 ± 17.9% at 360 days, 31.4 ± 24.0% at 540 days, and 0% at 720 days. The postintervention secondary patency was 100% at 90 days, 100% at 120 days, 100% at 180 days, 85.7 ± 13.2% at 360 days, and 85.7 ± 13.2% at 720 days. No major complications were noted. Minor complications were found in 71.4% of patients, all of which resolved spontaneously. In conclusion, endovascular treatment of fistulas with the eighth note deformity can effectively increase the number of available cannulation sites, facilitate fistula maturation, and facilitate thromboaspiration after fistula thrombosis.

An aortodigestive fistula can be revealed by a peripheral septic wound when patient have aortic endovascular prosthesis. Our clinical case is about a 69-year-old patient with an abscess of the lateral aspect of his left lower limb. He has been treated few years ago for an aorto-abdominal anevrysm by an aortobifemoral prosthesis. In spite of a negative initial assessment for an aortodigestive fistula, anaerobic germs were found into the abscess. The initial treatment associated debridement, negative pressure therapy, dermal substitute and a split thickness skin graft for the loss of cutaneous substance. Months later, in front of an unexplained skin healing delay and fever, we realised new assessment bringing to light an aortodigestive fistula. Furthermore, the local bacterial samples from the wound and the hemocultures found both a lot of Escherichia Coli. The change of the aorto-bifemoral prosthesis and the cure of the aortodigestive fistula allowed the complete healing of the loss of cutaneous substance of the leg. The aortodigestive fistulas have a very high mortality. Because of their difficult diagnosis, their clinical suspicion has to start a complete medical assessment. Every septic wound when patients have vascular prosthesis is suggestive of an aortodigestive fistula. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

Background The role of immune cells in arteriovenous fistulae (AVF) maturation is poorly understood and has received, until quite recently, little attention. This study examines the role of T lymphocytes in AVF vascular remodeling. Methods Experimental fistulae were created in athymic rnu nude rats lacking mature T lymphocytes and euthymic control animals by anastomosing the left superior epigastric vein to the nearby femoral artery. Blood flow rates, wall morphology and histological changes were assessed in AVF 21 days after creation. The effect of CD4+ lymphocytes on AVF maturation in athymic animals was analyzed by adoptive transfer of cells after fistula creation. Results The absence of T lymphocytes compromised blood flow in experimental fistulae. Histopathological inspection of AVF from athymic rats revealed that T cell immunodeficiency negatively affected venous vascular remodeling, as evidenced by a reduced lumen, a thick muscular layer and a low number of inflammatory cells compared to control animals. Adoptive transfer of CD4+ lymphocytes from euthymic rats into athymic animals before and after fistula creation improved blood flow and reduced intima-media thickness. Conclusion These results point at the protective role of CD4+ lymphocytes in the remodeling of the AVF vascular wall. PMID:25999254

To detect and analyze the characteristic miRNAs profile of anal fistula and explore their possible target genes and potential clinical significance. The anal mucosa close to the hemorrhoids were collected from three patients undergoing fistulectomy and hemorrhoidectomy (fistula group) as well as three patients receiving only hemorroidectomy(hemorrhoids group), matching with fistula group in age, gender and body weight. miRNA microarray was used to compare the expression of 1 285 human miRNAs of the anal mucosa between two groups. Cluster analysis was adopted to analyze the accumulation of the differentially expressed miRNAs(Pcharacteristic miRNAs profile in anal fistula patients, which may play a role in the occurrence and development of anal fistula.

The absorption of 212 Pb ions from bronchial epithelium to blood has been investigated in anaesthetized rabbits. The 212 Pb ions were introduced by intubation either into the trachea or into smaller, more distal bronchi. Removal from lung was followed by external γ-counting. Mucociliary clearance to the GI tract was blocked by tracheostomy. Two distinct phases of clearance from bronchial epithelium to blood were observed. Approximately 20% of deposited 212 Pb was rapidly absorbed with a half-time of about 4 min, the remainder with a biological half-time of about 9 h, irrespective of the site of instillation in the bronchial tree. Two hours after deposition, the 212 Pb remaining in lung was found to be partitioned between mucus and the bronchial epithelium, with a substantial but minor fraction in the epithelium. Uptake of 212 Pb in the skeleton was estimated to be about 20% of the 212 Pb entering the blood circulation. Removal by the kidneys, at 25%, was comparable with skeletal uptake. These results are compared with previously published work using rodents, dogs and man which demonstrated either rapid or slow absorption but not both phases occurring together. (author)

We tested the null hypothesis that there were no differences between patients with obstetric fistula and parous controls without fistula. A unmatched case-control study was carried out comparing 75 women with a history of obstetric fistula with 150 parous controls with no history of fistula. Height and weight were measured for each participant, along with basic socio-demographic and obstetric information. Descriptive statistics were calculated and differences between the groups were analyzed using Student's t test, Mann-Whitney U test where appropriate, and Chi-squared or Fisher's exact test, along with backward stepwise logistic regression analyses to detect predictors of obstetric fistula. Associations with a p value divorce/separation, and lived in more impoverished circumstances than controls. Fistula patients had worse reproductive histories, with greater numbers of stillbirths/abortions and higher rates of assisted vaginal delivery and cesarean section. The final logistic regression model found four significant risk factors for developing an obstetric fistula: age at marriage (OR 1.23), history of assisted vaginal delivery (OR 3.44), lack of adequate antenatal care (OR 4.43), and a labor lasting longer than 1 day (OR 14.84). Our data indicate that obstetric fistula results from the lack of access to effective obstetrical services when labor is prolonged. Rural poverty and lack of adequate transportation infrastructure are probably important co-factors in inhibiting access to needed care.

Full Text Available Introduction. The course of bronchial asthma in children is often accompanied by gastrointestinal (GI diseases associated with H.pylori infection. The presence of H.pylori leads to the activation and maintenance of inflammatory process with release of cytokines and mediators of inflammation and subsequent systemic effects. Objective: to study the peculiarities of interferon gamma (IFN-γ and interleukin (IL-4, -5 and -13 production as markers of allergic inflammation severity in children with bronchial asthma infected with H.pylori. Materials and methods. There were examined 120 children with bronchial asthma aged 6 to 18 years. Identification of H.pylori was carried out with the help of brea­thing Helic-test (LLC AMA, Russia. Serum concentrations of IFN-γ and IL‑4, -5 and -13 were determined by enzyme-linked immunoassay (Diaclone test-kits, France before and 7 days after the end of treatment for GI pathology. Statistical processing was performed using the methods of variation statistics implemented in the software package Statistica 6.1. Results. 78 children with bronchial asthma were diagnosed with GI disease, including 37 cases associated with H.pylori infection. To study the influence of H.pylori on the course of bronchial asthma, children were divided into 3 groups: I group — 37 children with bronchial asthma and GI pathology, infected with H.pylori, II — 41 H.pylori-negative children with bronchial asthma and GI pathology, III — 42 H.pylori-negative children with bronchial asthma without GI disorders. Duration of bronchial asthma in group I was 7.80 ± 0.17 years, in II — 5.90 ± 0.26 years, in group III — 3.90 ± 0.48 years (p < 0.05. The presence of H.pylori infection in children with bronchial asthma was accompanied by lower concentrations of IFN-γ compared to children of group II (8.47 ± 0.14 pg/ml and 9.69 ± 0.32 pg/ml, respectively, p < 0.05. The level of IL‑13 in the blood serum was

In patients with post-tuberculosis bronchial stenosis (PTBS), the severity of bronchial stenosis affects the restenosis rate after the silicone stent is removed. In PTBS patients with incomplete bronchial obstruction, who had a favorable prognosis, the timing of stent removal to ensure airway patency is not clear. We evaluated the time for silicone stent removal in patients with incomplete PTBS. A retrospective study examined PTBS patients who underwent stenting and removal of a silicone stent. Incomplete bronchial stenosis was defined as PTBS other than total bronchial obstruction, which had a luminal opening at the stenotic segment on bronchoscopic intervention. The duration of stenting was defined as the interval from stent insertion to removal. The study included 44 PTBS patients and the patients were grouped at intervals of 6 months according to the duration of stenting. Patients stented for more than 12 months had a significantly lower restenosis rate than those stented for less than 12 months (4% vs. 35%, P = 0.009). Multiple logistic regression revealed an association between stenting for more than 12 months and a low restenosis rate (odds ratio 12.095; 95% confidence interval 1.097-133.377). Moreover, no restenosis was observed in PTBS patients when the stent was placed more than 14 months previously. In patients with incomplete PTBS, stent placement for longer than 12 months reduced restenosis after stent removal.

Lymphogranuloma venereum (LGV) is a rare form of the sexually transmitted disease caused by Chlamydia trachomatis. In the United States, there are fewer than 350 cases per year. In a review of the world's literature, there has not been a case reported in the last thirty years of a case of LGV presenting as a rectovaginal fistula. We present a case of an otherwise healthy American woman who presented with a rectovaginal fistula. Although uncommon, LGV does occur in developed countries and may have devastating tissue destruction if not recognized and treated before the tertiary stage. PMID:10449269

Assessment of perianal fistulas is important to guide management of Crohn's disease (CD). Our objectives were to analyze the feasibility of magnetization transfer (MT) imaging to assess fistulas and to evaluate its contribution in assessing disease activity. During 15 months, all patients referred for perianal fistulas in CD underwent 3T-MRI including diffusion, T2/T1-weighted gadolinium-enhanced sequences and MT sequences (one with an off-resonance saturation pulse of 800 and one with 1200 Hz). We collected Van Assche score, fistula activity signs by analyzing T2, diffusion and contrast enhancement. We calculated MT ratio (MTR) with a ROI in the largest fistula. Twenty-nine patients (mean 34.9 years, range 17-53) were included. Van Assche score was 11.7, range 4-21. In 22 patients, the fistula presented with a bright T2 and diffusion signal with contrast enhancement, and was characterized as active. Mean MTR was respectively 47.2 (range 12-68) and 34.3 (range 11-57) at 800 and 1200 Hz. MTR at 800 Hz was significantly lower in non-active (34, range 12-55) than in active fistulas (51, range 24-68) (p < 0.02). MTR is feasible for the assessment of fistulas in CD and in the future could be used to help identify active and non-active fistulas. (orig.)

In this series, the authors describe a modification of the facial artery musculomucosal flap for oronasal fistula repair. The spacer facial artery musculomucosal flap technique is characterized by a pedicle inset into the retromolar trigone and palate, obviating a second operative stage. This was performed in 14 patients with a 5.2-cm mean fistula size. Average follow-up was 4.3 years, with one partial flap necrosis but no recurrent oronasal fistula. There was a mean decrease of 18 percent in the distance between the velum and the posterior pharyngeal wall. The spacer facial artery musculomucosal flap provides a single-stage reconstruction of oronasal fistula while lengthening the palate through a pushback mechanism. Although further study of velopharyngeal function is needed, the spacer facial artery musculomucosal flap may be beneficial for patients with a short velum and an oronasal fistula. Therapeutic, IV.

Obstructive sleep apnea syndrome (OSA) is associated with systemic and upper airway inflammation. Pharyngeal inflammation has a potential role in upper airway collapse, whereas systemic inflammation relates to cardiovascular morbidity. However, the presence of an inflammatory involvement of lower airway has been poorly investigated. The aim of the study was to demonstrate an inflammatory process at the bronchial level in patients with OSA and to analyze effects of continuous positive airway pressure (CPAP) application and humidification on bronchial mucosa. The study was conducted by using sequential induced sputum for cell analysis and IL-8 production, nitric oxide exhalation measurement, and methacholine challenge before and after CPAP. Bronchial neutrophilia and a high IL-8 concentration were observed in untreated OSA compared with controls (75% +/- 20% vs 43% +/- 12%, P Obstructive sleep apnea syndrome is associated with bronchial inflammation. Our data demonstrate CPAP effect on the development of AHR, possibly facilitated by the pre-existing inflammation. Both issues should be evaluated during long-term CPAP use. Results showing a spontaneous bronchial inflammation in OSA and the development of a CPAP-related AHR require a long-term follow-up to evaluate consequences on chronic bronchial obstruction.

Objective: To investigate the establishment and bronchial arteriography of the models of canine lung cancer, and to facilitate further diagnosis and treatment of lung cancer. Methods: Twenty-two dogs were respectively administrated with 3 ml suspension of lipiodol-ultrafluid mixed with 3- methylcholanthrene (MCA) and diethylnitrosamine (DEN). The suspension was injected into the diaphragmic lobe of right lung with the co-axial catheter through endotracheal intubation. The dogs were randomly divided into 5 groups, group A (4 dogs), B (4), C (4), D (5), and E (5), which were sacrificed after observation for 1, 3, 6, 12, and 18 months, respectively. Then the image analysis and histopathologic examinations were carried out at different period. 5 dogs in group E were examined by bronchial arteriography. Results: Peribronchiolitis and atelectasis appeared at early stage (one month). Chronic granulomatous inflammation and fibrosis of lung tissue were gradually formed after 3 months. Proliferation of stem cells in bronchioles and atypical hyperplasia were found from 6 to 12 months. At last, the squamous carcinoma and bronchioloalveolar carcinoma were induced after 18 months. The lung cancer and precancerous lesion were found in 4 of 5 dogs at the 18 th month. The bronchial arteriography in the 5 dogs showed that 3 bronchial arteries were found as the supplying blood artery to the tumor. Conclusion: The suspension of lipiodol-ultrafluid mixed with MCA and DEN was exactly injected with the co-axial catheter through endotracheal intubation to establish the models of canine lung cancer. The inducible rate of the method was high and the location of lung cancer was accurate. It was affirmed that the blood supply artery of canine lung cancer was bronchial artery. Bronchial arteriography was of momentous significance to the diagnosis of early lung cancer. The establishment of the models of canine lung cancer was significant in the diagnosis and treatment of lung cancer. The models

Congenital coronary artery fistula (CCAF) is communication of a coronary artery or its main branch with one of the atria or ventricles, the coronary sinus, the superior vena cava, or the pulmonary artery. In Korean peoples, only 4 cases of the CCAF were reported as rare as worldwide and authors want to report another case of CCAF, confirmed by operation. 10-year-old girl shows a fistula between sinus node artery of the right coronary artery and right atrium on root aortogram with left-to-right shunt and Qp/Qs=1.58, in which simple ligation of the sinus node artery from right coronary artery was performed. All of the 5 Korean CCAF (4 were previously reported and 1 of authors) were originated from right coronary artery, and of which 4 were opening into right ventricle and 1 of authors were into right atrium. Associated cardiac anomaly was noted in only 1 case as single coronary artery. Ages were from 9 months of age to 10 years old and no adult left case were found. 3 were female and 2 were male patients.

Indirect carotid-cavernous fistula or dural arterio-venous fistula of cavernous sinus is relatively rare pathologic finding. Different classifications of carotid-cavernous fistulae are proposed. Now days more and more they are treated by endovascular approach. A case of authors' practice of transvenous embolization of carotid-cavernous fistula via upper ophthalmic vein in 52 year old female is presented with review of the literature. A week later ocular symptoms of the patient regressed. Control angiography at the third month follow up does not visualize fistula. The transvenous approach in management of carotid cavernous fistulae is safe and effective in cases direct arterial approach is absent or technically impossible.

Carotid-cavernous fistulas (CCFs) are anomalous communications between the carotid arterial system and the venous cavernous sinus. They can arise because of spontaneous or trauma causes. Most caroticocavernous fistulas are of spontaneous origin and unknown etiology. Spontaneous CCF may also be associated with cavernous sinus pathology such as arteriosclerotic changes of the arterial wall, fibromuscular dysplasia, or Ehler-Danlos syndrome. Traumatic CCFs may occur after either blunt or penetrating head trauma. Their clinical presentation is related to their size and to the type of venous drainage, which can lead to a variety of symptoms, such as visual loss, proptosis, bruit, chemosis, cranial nerve impairment, intracranial hemorrhage (rare), and so on. Treatment by endovascular transarterial embolization with electrolytically detachable coils is a very effective method for CCF with good outcomes. Carotid-cavernous fistulas have been rarely reported after craniofacial surgery and are uncommon pathologies in otolaryngology practice. In this study, we report a 40-year-old woman with CCF secondary to blunt trauma of functional endoscopic sinus surgery.

Tracheoesophageal Fistula due to a Damaged Tracheal Stent

Full Text Available We describe the management of a tracheoesophageal fistula due to a damaged tracheal stent, which was first inserted to treat tracheal stenosis. A 29-year-old woman with a history of treated epilepsy had a seizure and suffered from smoke inhalation during a fire. Breathing difficulties appeared and gradually worsened; consultation was obtained two years afterward. After undergoing a thorough examination, the patient was diagnosed with tracheal strangulation. A noncovered, metallic stent was inserted. When the patient was 37 years old, she was admitted to our hospital for the treatment of a tracheoesophageal fistula. We diagnosed it as a tracheoesophageal fistula due to the collapse of the damaged tracheal stent toward the esophageal side, and we decided to perform a mediastinal tracheostomy. Granulation may be formed in the circumference of a stent that has been present for a prolonged period, and removal of the stent may become difficult. This case suggests that insertion of a noncovered, metallic stent is contraindicated for a benign disease.

Purpose: To evaluate the efficacy of percutaneous drainage of fluid collections following pancreaticoduodenectomy (Whipple's procedure). Methods: We performed a retrospective review of 19 patients referred to our service with fluid collections following pancreaticoduodenectomy. The presence of associated enteric or biliary fistulas, the route(s) of access for image-guided drainage, the incidence of positive bacterial cultures, and the duration and success of percutaneous management were recorded. Results: Fistulous communication to the jejunum in the region of the pancreatico-jejunal anastomosis was demonstrable in all 19 patients by gentle contrast injection into drainage tubes. Three patients had concurrent biliary fistulas. In 18 of 19 patients, fluid samples yielded positive bacterial cultures. Successful percutaneous evacuation of fluid was achieved in 17 of 19 patients (89%). The mean duration of drainage was 31 days. Conclusion: Percutaneous drainage of abscess following pancreaticoduodenectomy is effective in virtually all patients despite the coexistence of enteric and biliary fistulas

Arteriobiliary fistula is a rare complication of hepatic intra-arterial chemotherapy. We report successful coil embolization of an arteriobiliary fistula. An 80-year-old woman underwent percutaneous placement of an indwelling catheter into the replaced right hepatic artery for intra-arterial chemotherapy of liver metastases. Coil embolization of the left hepatic artery was not performed. The patient complained of abdominal pain during intra-arterial chemotherapy. Angiography revealed a fistula between the replaced right hepatic artery and the common bile duct. The fistula was successfully treated by coil embolization via the indwelling catheter, and the indwelling catheter was removed. Although such complications usually herald the termination of intra-arterial chemotherapy, the patient underwent percutaneous implantation of a new catheter-port system, and intra-arterial chemotherapy was restarted

Purpose: To treat the esophagotracheal fistula that was the main cause of death in patients with esophageal carcinoma, the placement of the stent was studied. Materials and methods: Under the fluoroscopic guidance, 28 stents (5 stents made in USA and 23 in China) were successfully implanted in all the 28 patients with esophagotracheal fistula. Results: The aphagia of the patients was greatly improved and a normal diet could be swallowed at once after the placement of the stents. The 27 cases of inhalation pneumonia that caused by the fistula was recovered. Conclusion: The result indicated that the treatment with the placement of the covered self-expanding stent is simple, safe, and effective for most patients with aphagia and pneumonia due to esophagotracheal fistula

A 22-year-old man suffered a hiking accident with perineal trauma and developed a nonpainful priapism secondary to bilateral arterial-cavernosal fistulas. To minimize the risk of impotence in this young patient, successive selective embolizations with autologous blood clot were performed to close the fistulas. This led to an uncomplicated full recovery. No fistula was detectable on Doppler ultrasonography at 1-year follow-up. Review of the literature confirms the safety of embolization with autologous clot

Full Text Available The prevalence of congenital abnormalities of coronary artery is about 2% of general population. Of these abnormalities 5% were related to coronary artery fistulae (CAF. We report a case of 66 year old diabetic woman who presented with retrosternal chest pain. Her chest pain was associated with exercise and progressively deteriorated over the last 6 months. Electrocardiography showed right bundle branch block and Echo Color Doppler revealed hypo kinetic lateral wall. Coronary angiogram detected nothing abnormal except an aberrant tortuous branch of left circumflex. CT scan revealed a calcified sac medial to the descended thoracic aorta. A contrast enhancement was also done. All these imaging impressions were suggestive of coronary-to-pulmonary fistula. Ibrahim Med. Coll. J. 2007; 1(1: 32-33

Pulmonary hemodynamic disorders depend on the inflammatory phases and severity of the obstructive syndrome. However, the effect of asthma bronchial obstruction on the state of peripheral hemodynamics remains insufficiently known. To study the effects of airway obstruction on skin blood flow parameters and its regulatory systems in patients with persistent atopic bronchial asthma in the remission state. A comparative study of the skin peripheral blood flow in patients with bronchial asthma with severe airway obstruction (1st group) and without obstruction (2nd group) was conducted. 20 patients with confirmed diagnosis of atopic asthma of 50–74 years old participated in the study. All patients received basic therapy in a constant dosing of high doses of inhaled glucocorticosteroids/long-acting beta-2-agonists. The control group included 20 healthy volunteers without evidence of bronchial obstruction. The study lasted for 3 months. The forced expiratory volume in 1 s (FEV1) was used to evaluate the bronchial obstruction by spirometry technique. Skin blood perfusion changes were recorded by laser Doppler flowmetry at rest and in response to short-term local ischemia. Registered peripheral blood flow signals were examined using the amplitude temporal filtering in five frequency intervals to identify the functional features of the peripheral blood flow regulation systems. Consistent two-fold decrease of the oscillation amplitudes was found in the neurogenic interval at rest (p=0.031), as well as in the myogenic (p=0.043; p=0.031) and endothelial intervals (p=0.037; p≤0.001) both at rest and during the postocclusive reactive hyperemia respectively in the 1st group of patients with bronchial obstruction (FEV1 obstruction, FEV1 >80%) in comparison to control subjects. The presence of bronchial obstruction has a significant impact on the changes of the amplitudes of skin blood flow oscillations in patients with bronchial asthma in the myogenic, neurogenic and endothelial

Full Text Available Coronary artery fistula (CAF is a rare congenital anomalywith an incidence of 1 in 50 000 live births. The fistula wasobserved at the right coronary artery in 53%, the left coronaryartery in 42% and both coronary artery in 5% of thecases. Echocardiography examination in a 46 year-oldwoman with the symptoms of chest pain, palpitation anddyspnea revealed a severe mitral valve insufficiency anda moderate to severe tricuspid valve insufficiency. A CAForiginating from the proximal part of the left anterior descendingartery (LAD and another fistula originating fromosteal part of the right coronary artery (RCA were detectedby coronary angiography. Both fistulas were draininginto the main pulmonary artery. The coronary artery fistulaclosed under cardiopulmonary by-pass. Mitral insufficiencyoriginated from the posterior leaflet was diagnosedintra-operative exploration, and thereafter it was repairedwith mitral annuloplasty including a quadrangular resectionand use of a 32 No St Jude mitral ring. Tricuspid valvewas repaired with Calangos Ring annuloplasty. Followingsix day hospital stay, the woman was discharged free ofany symptom.Key words: Dyspnea, double arteriovenous fistula, mitral and tricuspid insufficiency

Purpose: To evaluate the dose–response relationship between radiation-induced atelectasis after stereotactic body radiation therapy (SBRT) and bronchial dose. Methods and Materials: Seventy-four patients treated with SBRT for tumors close to main, lobar, or segmental bronchi were selected. The association between incidence of atelectasis and bronchial dose parameters (maximum point-dose and minimum dose to the high-dose bronchial volume [ranging from 0.1 cm 3 up to 2.0 cm 3 ]) was statistically evaluated with survival analysis models. Results: Prescribed doses varied between 4 and 20 Gy per fraction in 2-5 fractions. Eighteen patients (24.3%) developed atelectasis considered to be radiation-induced. Statistical analysis showed a significant correlation between the incidence of radiation-induced atelectasis and minimum dose to the high-dose bronchial volumes, of which 0.1 cm 3 (D 0.1cm3 ) was used for further analysis. The median value of D 0.1cm3 (α/β = 3 Gy) was EQD 2,LQ = 147 Gy 3 (range, 20-293 Gy 3 ). For patients who developed atelectasis the median value was EQD 2,LQ = 210 Gy 3 , and for patients who did not develop atelectasis, EQD 2,LQ = 105 Gy 3 . Median time from treatment to development of atelectasis was 8.0 months (range, 1.1-30.1 months). Conclusion: In this retrospective study a significant dose–response relationship between the incidence of atelectasis and the dose to the high-dose volume of the bronchi is shown

A 28-year-old G1P1 presented complaining of urine leakage per vaginum following caesarean delivery, accompanied by amenorrhoea, cyclic haematuria and cyclic pelvic pain. Examination findings were suggestive of vesicouterine fistula and the patient was taken for exploratory laparotomy, during which the foley catheter could not be identified within the bladder. During separation of the bladder from the uterus, the catheter was found to be traversing the fistulous tract into the uterine cavity. Vesicouterine fistula is a fairly uncommon type of urogenital fistula that is frequently associated with caesarean section. Surgical treatment remains the mainstay and successfully cured this patient. Published by Oxford University Press and JSCR Publishing Ltd. All rights reserved. © The Author 2013.

A 53-year old female visited our hospital with a complaint of continuous urinary incontinence after sexual intercourse. She had been diagnosed with carcinoma of uterine cervix stage I b2 and had undergone radical hysterectomy and radiation therapy (45 Gy). Cystoscopy revealed vesicovaginal fistula in the trigone which measured almost 3 cm. We repaired it by transabdominal and vaginal routes 5 days after the injury. She was discharged with a Foley catheter. Three months after the operation, cystography revealed improvement of vesicovaginal fistula. (author)

Thalhammer, A.; Jacobi, V.; Balzer, J.; Straub, R.; Vogl, T.J.

2002-01-01

Introduction: Acute pulmonary emergencies in patient with cystic fibrosis (CF) can be found in cases of pneumothorax as well as hemoptysis. If the bleeding cannot be stopped by conservative methods, an embolization of the bronchial arteries should be done. Materials and Method: 11 patients were embolized using a combination of PVA particles and microcoils. Results: From January 1996 to June 2001 17 bronchial arteries in 11 patients were embolized. 7 patients suffered from chronical hemoptysis, 4 patients had an acute hemoptysis. In 4 patients both sides were embolized, in 3 patients only one side. The remaining 4 patients needed a second intervention, embolizing the other side. The primary embolizated bronchial artery was still closed in all 4 patients. In 1 patient the selective catheterization of a bronchial artery was not successful, thus the embolization could not be carried out. 1 patient died 5 days after the intervention due to a fulminant pneumonia (Pseudomonas aeruginosa) without recurrent bleeding. In two patients atypical branches from intercostal arteries feeding the bronchial arteries were detected and successfully embolized. All patients profited from the therapy, as bleeding could be stopped or at least be reduced. 3 patients suffered from back pain during or after intervention. There were no severe complications like neurological deficiencies or necroses. (orig.) [de

Diagnosis of a colovesical fistula is often challenging, and usually involves numerous invasive and expensive tests and procedures. The poppy seed test stands out as an exception to this rule. We evaluated the accuracy and cost-effectiveness of various established diagnostic tests used to evaluate a suspected colovesical fistula. We identified 20 prospectively entered patients with surgically confirmed colovesical fistulas between 2000 and 2006. Each patient was evaluated preoperatively with a (51)chromium nuclear study, computerized tomography of the abdomen and pelvis with oral and intravenous contrast medium, and the poppy seed test. Costs were calculated using institutional charges, 2006 Medicare limiting approved charges and the market price, respectively. The z test was used to compare the proportion of patients who tested positive for a fistula with each of these modalities. The chromium study was positive in 16 of 20 patients (80%) at a cost of $490.83 per study. Computerized tomography was positive in 14 of 20 patients (70%) at a cost of $652.92 per study. The poppy seed test was positive in 20 of 20 patients (100%) at a cost of $5.37 per study. The difference in the proportion of patients who tested positive for a fistula on computerized tomography and the poppy seed test was statistically significant (p = 0.03). There was no difference between the chromium group and the computerized tomography or poppy seed group (p = 0.72 and 0.12, respectively). The poppy seed test is an accurate, convenient and inexpensive diagnostic test. It is an ideal initial consideration for evaluating a suspected colovesical fistula.

Pharyngocutaneous or esophagocutaneous fistula formation is not a rare complication after surgical treatment of head/neck cancer. In cases having developed such fistula, conservative treatment with local manipulation or surgical closure of the fistula using a local or pedicled flap is often possible. We recently encountered a case with an intractable gastrocutaneous fistula which occurred a long time after gastric pull-up reconstruction of the pharynx and esophagus. The patient was a 58-year-old female. As treatment for hypopharyngeal and thoracic esophageal cancers, the patient underwent total resections of the laryngopharynx and esophagus and gastric pull-up reconstruction of the esophagus. Postoperatively, 50 Gy radiation was applied to the neck. Although there was no recurrence of cancer, a salivary fistula above the tracheostomy occurred six years after surgery. Closure of the fistula with a local flap was attempted twice, but did not succeed. The fistula was then closed with a deltopectoral (DP) flap, but a fistula recurred five months later. Finally, by resecting the cervical segment of the pulled-up stomach, the esophagus was reconstructed successfully with a free jejunal graft. An intractable fistula should be replaced using tissue with rich blood flow, such as a free jejunal graft. (author)

Heart Failure with Transient Left Bundle Branch Block in the Setting of Left Coronary Fistula

2011-01-01

Full Text Available Coronary arterial fistulas are rare communications between vessels or chambers of the heart. Although cardiac symptoms associated with fistulas are well described, fistulas are seldom considered in the differential diagnosis of acute myocardial ischemia. We describe the case of a 64-year-old man who presented with left shoulder pain, signs of heart failure, and a new left bundle branch block (LBBB. Cardiac catheterization revealed a small left anterior descending (LAD-to-pulmonary artery (PA fistula. Diuresis led to subjective improvement of the patient's symptoms and within several days the LBBB resolved. We hypothesize that the coronary fistula in this patient contributed to transient ischemia of the LAD territory through a coronary steal mechanism. We elected to observe rather than repair the fistula, as his symptoms and ECG changes resolved with treatment of his heart failure.

Recently, we described a model system which included corrections of high-resolution computed tomography (HRCT) bronchial measurements based on the adjusted subpixel method (ASM). To verify the clinical application of ASM by comparing bronchial measurements obtained by means of the traditional eye-driven method, subpixel method alone and ASM in a group comprised of bronchial asthma patients and healthy individuals. The study included 30 bronchial asthma patients and the control group comprised of 20 volunteers with no symptoms of asthma. The lowest internal and external diameters of the bronchial cross-sections (ID and ED) and their derivative parameters were determined in HRCT scans using: (1) traditional eye-driven method, (2) subpixel technique, and (3) ASM. In the case of the eye-driven method, lower ID values along with lower bronchial lumen area and its percentage ratio to total bronchial area were basic parameters that differed between asthma patients and healthy controls. In the case of the subpixel method and ASM, both groups were not significantly different in terms of ID. Significant differences were observed in values of ED and total bronchial area with both parameters being significantly higher in asthma patients. Compared to ASM, the eye-driven method overstated the values of ID and ED by about 30% and 10% respectively, while understating bronchial wall thickness by about 18%. Results obtained in this study suggest that the traditional eye-driven method of HRCT-based measurement of bronchial tree components probably overstates the degree of bronchial patency in asthma patients.

Background This study was conducted to investigate the risk factors of anastomotic fistula after the radical resection of esophageal‐cardiac cancer. Methods Five hundred and forty‐four esophageal‐cardiac cancer patients who underwent surgery and had complete clinical data were included in the study. Fifty patients diagnosed with postoperative anastomotic fistula were considered the case group and the remaining 494 subjects who did not develop postoperative anastomotic fistula were considered the control. The potential risk factors for anastomotic fistula, such as age, gender, diabetes history, smoking history, were collected and compared between the groups. Statistically significant variables were substituted into logistic regression to further evaluate the independent risk factors for postoperative anastomotic fistulas in esophageal‐cardiac cancer. Results The incidence of anastomotic fistulas was 9.2% (50/544). Logistic regression analysis revealed that female gender (P < 0.05), laparoscopic surgery (P < 0.05), decreased postoperative albumin (P < 0.05), and postoperative renal dysfunction (P < 0.05) were independent risk factors for anastomotic fistulas in patients who received surgery for esophageal‐cardiac cancer. Of the 50 anastomotic fistulas, 16 cases were small fistulas, which were only discovered by conventional imaging examination and not presenting clinical symptoms. All of the anastomotic fistulas occurred within seven days after surgery. Five of the patients with anastomotic fistulas underwent a second surgery and three died. Conclusion Female patients with esophageal‐cardiac cancer treated with endoscopic surgery and suffering from postoperative hypoproteinemia and renal dysfunction were susceptible to postoperative anastomotic fistula.

Obstetric fistula is a devastating childbirth injury caused by unrelieved obstructed labor. Obstetric fistula leads to chronic incontinence and, in most cases, significant physical and emotional suffering. The condition continues to blight the lives of 1-2 million women in low-resource settings, with 50 000-100 000 new cases each year adding to the backlog. A trained, skilled fistula surgeon is essential to repair an obstetric fistula; however, owing to a global shortage of these surgeons, few women are able to receive life-restoring treatment. In 2011, to address the treatment gap, FIGO and partners released the Global Competency-Based Fistula Surgery Training Manual, the first standardized curriculum to train fistula surgeons. To increase the number of fistula surgeons, the FIGO Fistula Surgery Training Initiative was launched in 2012, and FIGO Fellows started to enter the program to train as fistula surgeons. Following a funding boost in 2014, the initiative has grown considerably. With 52 fellows involved and a new Expert Advisory Group in place, the program is achieving major milestones, with a record-breaking number of fistula repairs performed by FIGO Fellows in 2017, bringing the total number of repairs since the start of the project to more than 6000. © 2018 International Federation of Gynecology and Obstetrics.

In patients diagnosed with anal fistula, knowing the quality of life specifically related to the disease can help coloproctology specialists to choose the most appropriate therapeutic strategy for each case. The aim of our study is to analyzse and describe the factors related to the specific quality of life in a consecutive series of patients diagnosed with anal fistula. Observational, cross-sectional study carried out from March 2015 to February 2017. All patients were assessed in the colorectal surgery unit of a hospital in southeast of Spain. After performing an initial anamnesis and a physical examination, patients diagnosed with anal fistula completed the Quality of Life in Ppatients with Anal Fistula Questionnaire (QoLAF-Q). This questionnaire specifically measures quality of life in people with anal fistula and its score range is the following: zero impact = 14 points, limited impact = 15 to 28 points, moderate impact = 29 to 42 points, high impact = 43 to 56 points, and very high impact = 57 to 70 points. A total of 80 patients were included. The median score obtained in the questionnaire for the sample studied was 34.00 (range=14-68). Statistically significant differences between patients with "primary anal fistula" (n=65) and "recurrent anal fistula" (n=15) were observed (mean rank=42.96 vs. mean rank=29.83, p=0.048). Furthermore, an inverse proportion (P=.016) between "time with clinical symptoms" and "impact on quality of life" was found (5 years: mean rank = 19.00). There were no statistically significant differences (P=.149) between quality of life amongst patients diagnosed with complex (mean rank = 36.13) and simple fistulae (mean rank = 43.59). Anal fistulae exert moderate-high impact on patients' quality of life. "Shorter time experiencing clinical symptoms" and the "presence of primary fistula" are factors that can be associated with worse quality of life. Copyright © 2018 AEC.

We have devised a modified seton technique that resects the external fistula tract while preserving the anal sphincter muscle. This study assessed the technique when used for the management of complex anal fistulas. Between January 2006 and December 2007, 239 patients (208 males and 31 females, median age: 41 years) underwent surgery for complex anal fistulas using the technique. Of the 239 patients, 198 patients had trans-sphincteric fistula and 41 patients had supra-sphincteric fistula. The durations of the surgeries were 17 min (47, 13) [median (range, interquartile range)] for trans-sphincteric fistulas and 38 (44, 16) for supra-sphincteric fistulas. The durations of the surgeries were significantly (P trans-sphincteric fistula. The hospital stays were 4 (13, 2) days and 5 (14, 3) days, respectively, for trans- and supra-sphincteric fistulas. The durations of seton placement until the spontaneous dropping of the seton were 42 (121, 48) and 141 (171, 55) days respectively. The recurrence rate was 0 % in patients with trans-sphincteric fistulas and 4.9 % (2 of 41) in patients with supra-sphincteric fistulas (P < 0.01). Serious incontinence was not observed. The technique provided favorable results for the treatment of complex anal fistulas and could be safely applied while preserving the sphincter function and conserving fecal continence.

Nuclear angiocardiography with sup(99m)TcO 4 - was performed for the purpose of the delineation of the systemic perfusion in various lung diseases, using a scintillation camera with a digital minicomputer system. The images of the bronchial blood flow were obtained in cases with primary lung cancer, pulmonary tuberculosis, lung abscess, bronchiectasis and chronic bronchitis. The fair images of the bronchial blood flow were taken in cases of peripheral type, adenocarcinoma and primary foci of atelectatic type in primary lung cancer. The grade of delineation of the bronchial blood flow and vascularity of bronchial artery in foci of primary lung cancer were correlative to the grade of accumulation of 197 HgCl 2 , respectively. The joint use of nuclear angiocardiography and other imagings such as tumor or perfusion one was useful for evaluation of the pulmonary and systemic circulation, and that made isotope diagnosis of primary lung cancer more reliable too. The image as a isocount map extracted out of the image of 197 HgCl 2 or sup(99m)Tc-MAA, was superimposed to the brightness image of the nuclear angiocardiogram (aortic phase). This image superimposition methods were valuable to improve anatomic orientation of the nuclear angiocardiogram. The delineation of the bronchial blood flow on the subtraction image, which obtained from the two time-different images in aortic phase of the nuclear angiocardiogram, was better than that of the original images.

2013-01-01

Full Text Available Context: In patients with post-tuberculosis bronchial stenosis (PTBS, the severity of bronchial stenosis affects the restenosis rate after the silicone stent is removed. In PTBS patients with incomplete bronchial obstruction, who had a favorable prognosis, the timing of stent removal to ensure airway patency is not clear. Aims: We evaluated the time for silicone stent removal in patients with incomplete PTBS. Settings and Design: A retrospective study examined PTBS patients who underwent stenting and removal of a silicone stent. Methods: Incomplete bronchial stenosis was defined as PTBS other than total bronchial obstruction, which had a luminal opening at the stenotic segment on bronchoscopic intervention. The duration of stenting was defined as the interval from stent insertion to removal. The study included 44 PTBS patients and the patients were grouped at intervals of 6 months according to the duration of stenting. Results: Patients stented for more than 12 months had a significantly lower restenosis rate than those stented for less than 12 months (4% vs. 35%, P = 0.009. Multiple logistic regression revealed an association between stenting for more than 12 months and a low restenosis rate (odds ratio 12.095; 95% confidence interval 1.097-133.377. Moreover, no restenosis was observed in PTBS patients when the stent was placed more than 14 months previously. Conclusions: In patients with incomplete PTBS, stent placement for longer than 12 months reduced restenosis after stent removal.

To assess bronchial morphology and abnormality, 14 children with congenital heart diseases including 2 postoperative patients (age, 2 m.-4 yr) were studied by digital video subtraction fluorography (DVSF) using digital subtraction and image processing system (Philips, DVI-2). This newly developed technique clearly defined bronchial anatomy in all 14 patients. Bronchial situs could be determined in all 8 patients with complex heart anomalies. Out of 8 patients with respiratory distress in this study, obvious bronchial stenosis or obstruction was found by DVSF in 5 patients. Thus, DVSF image defined anatomies of main and lobar bronchi more clearly than previous noninvasive methods. Moreover, DVSF is noninvasive and easily performed even for small infants and critically ill patients. In conclusion, DVSF may be a useful technique to assess bronchial morphology and abnormality in patients with congenital heart diseases. (author)

The Use of Extracorporeal Membrane Oxygenation in the Surgical Repair of Bronchial Rupture

2016-02-01

Full Text Available Extracorporeal membrane oxygenation (ECMO has been used successfully in critically ill patients with traumatic lung injury and offers an additional treatment modality. ECMO is mainly used as a bridge treatment to delayed surgical management; however, only a few case reports have presented the successful application of ECMO as intraoperative support during the surgical repair of traumatic bronchial injury. A 38-year-old man visited our hospital after a blunt chest trauma. His chest imaging showed hemopneumothorax in the left hemithorax and a finding suspicious for left main bronchus rupture. Bronchoscopy was performed and confirmed a tear in the left main bronchus and a congenital tracheal bronchus. We decided to provide venovenous ECMO support during surgery for bronchial repair. We successfully performed main bronchial repair in this traumatic patient with a congenital tracheal bronchus. We suggest that venovenous ECMO offers a good option for the treatment of bronchial rupture when adequate ventilation is not possible.

1975-09-01

Diagnostic and therapeutic problems in a patient with ectopic ACTH syndrome caused by a malignant bronchial adenoma are discussed. Persistent Cushing's syndrome was present following apparent total adrenalectomy, but radioactive scanning with 131I-19-iodocholesterol showed the presence of residual adrenal tissue in the right suprarenal bed. Amelioration of the hypercortisolism occurred after removal of the bronchial adenoma. A paradoxical elevation of adrenocortical activity followed administration of dexamethasone and data are presented which suggest that periodic secretion of ACTH accounted for this phenomenon.

Only type A CCF patients (Barrow's classification) would be recruited for the study. Based on the angiographic characteristics of the CCF, we classified type A CCF into three subtypes including small size, medium size and large size fistula depending on whether there was presence of the anterior carotid artery (ACA) and/or middle carotid artery (MCA). Angiograms with opacification of both ACA and MCA were categorized as small size fistula. Angiograms with opacification of either ACA or MCA were categorized as medium size fistula and those without opacification of neither ACA nor MCA were classified as large size fiatula. After the confirm angiogram, endovascular embolization would be performed impromptu using detachable balloon, coils or both. All cases were followed up for complication and effect after the embolization. A total of 172 direct traumatic CCF patients were enrolled. The small size fistula was accountant for 12.8% (22 cases), medium size 35.5% (61 cases) and large size fistula accountant for 51.7% (89 cases). The successful rate of fistula occlusion under endovascular embolization was 94% with preservation of the carotid artery in 70%. For the treatment of each subtype, a total of 21/22 cases of the small size fistulas were successfully treated using coils alone. The other single case of small fistula was defaulted. Most of the medium and large size fistulas were cured using detachable balloons. When the fistula sealing could not be obtained using detachable balloon, coils were added to affirm the embolization of the cavernous sinus via venous access. There were about 2.9% of patient experienced direct carotid artery puncture and 0.6% puncture after carotid artery cut-down exposure. About 30% of cases experienced

Omalizumab therapy of non-atopic asthmatics reduces bronchial mucosal IgE and inflammation and preserves/improves lung function when disease is destabilised by staged withdrawal of therapy.18 symptomatic, non-atopic asthmatics were randomised (1:1) to receive omalizumab or identical placebo treatment in addition to existing therapy for 20 weeks. Bronchial biopsies were collected before and after 12-14 weeks of treatment, then the patients destabilised by substantial, supervised reduction of their regular therapy. Primary outcome measures were changes in bronchial mucosal IgE + cells at 12-14 weeks, prior to regular therapy reduction, and changes in lung function (forced expiratory volume in 1 s) after destabilisation at 20 weeks. Quality of life was also monitored.Omalizumab but not placebo therapy significantly reduced median total bronchial mucosal IgE + cells (pomalizumab treated patients, with significant differences in absolute (p=0.04) and % predicted forced expiratory volume in 1 s (p=0.015).Omalizumab therapy of non-atopic asthmatics reduces bronchial mucosal IgE + mast cells and improves lung function despite withdrawal of conventional therapy.

Perianal fistula surgery can damage the anal sphincters which may cause faecal incontinence. By measuring regional pressures, 3D-HRAM potentially provides better guidance for surgical strategy in patients with perianal fistulas. The aim was to measure regional anal pressures with 3D-HRAM and to compare these with 3D-EUS findings in patients with perianal fistulas. Consecutive patients with active perianal fistulas who underwent both 3D-EUS and 3D-HRAM at a clinic specialised in proctology were included. A group of 30 patients without fistulas served as controls. Data regarding demographics, complaints, previous perianal surgical procedures and obstetric history were collected. The mean and regional anal pressures were measured with 3D-HRAM. Fistula tract areas detected with 3D-EUS were analysed with 3D-HRAM by visual coding and the regional pressures of the corresponding and surrounding area of the fistula tract areas were measured. The study was granted by the VUmc Medical Ethical Committee. Forty patients (21 males, mean age 47) were included. Four patients had a primary fistula, 19 were previously treated with a seton/abscess drainage and 17 had a recurrence after previously performed fistula surgery. On 3D-HRAM, 24 (60%) fistula tract areas were good and 8 (20%) moderately visible. All but 7 (18%) patients had normal mean resting pressures. The mean resting pressure of the fistula tract area was significantly lower compared to the surrounding area (47 vs. 76 mmHg; p < 0.0001). Only 2 (5%) patients had a regional mean resting pressure < 10 mmHg of the fistula tract area. Using a Δ mean resting pressure ≥ 30 mmHg difference between fistula tract area and non-fistula tract area as alternative cut-off, 21 (53%) patients were identified. In 6 patients 3D-HRAM was repeated after surgery: a local pressure drop was detected in one patient after fistulotomy with increased complaints of faecal incontinence. Profound local anal pressure drops are found

Obscure pulmonary masses: bronchial impaction revealed by CT

1983-01-01

Dilated bronchi impacted with mucus or tumor are recognized on standard chest radiographs because they are surrounded by aerated pulmonary parenchyma. When imaged in different projections, these lesions produce a variety of appearances that are generally familiar. This report characterizes less familiar computed tomographic (CT) findings in eight patients with pathologic bronchial distension of congenital, neoplastic, or infectious etiologies and correlates them with chest films. In seven patients, CT readily revealed dilated bronchi and/or regional lung hypodensity. In four of these cases, CT led to the initial suspicion of dilated bronchi. CT should be used early in the evaluation of atypical pulmonary mass lesions or to confirm suspected bronchial impaction because of the high probability it will reveal diagnostic features

Full Text Available Abstract Background Gastrocolic fistula is a rare presentation of both benign and malignant diseases of the gastrointestinal tract. Malignant gastrocolic fistula is most commonly associated with adenocarcinoma of the transverse colon in the Western World. Despite radical approaches to treatment, long-term survival is rarely documented. Case presentation We report a case of a 24-year-old woman who presented with the classic triad of symptoms associated with gastrocolic fistula. Radical en-bloc surgery and adjuvant chemotherapy were performed. She is still alive ten years after treatment. Conclusions Gastrocolic fistula is an uncommon presentation of adenocarcinoma of the transverse colon. Radical en-bloc surgery with adjuvant chemotherapy may occasionally produce long-term survival.

Full Text Available There were performed Doppler echocardiography investigations of functional state of the right heart in 42 children aged 5–17 years old in attack period of bronchial asthma of moderate to severe degree. Changes of intra-cardiac hemodynamics of the right heart in children in attack period of bronchial asthma were characterized by disturbance of systolic and diastolic function of the right ventricle and right atrium. Combined systolic-diastolic variant of the right ventricle dysfunction was typical for attack period of bronchial asthma in children and developed in 95.5 % of cases. Elevation of pressure in pulmonary artery was typical and significantly more often occurred in severe asthma attack, herewith pulmonary hypertension of the second degree predominated.

Full Text Available OBJECTIVE: Recto-urethral fistula formation following radical prostatectomy is an uncommon but potentially devastating event. There is no consensus in the literature regarding the treatment of these fistulas. We present here our experiences treating recto-urethral fistulas. MATERIAL AND METHODS: We analyzed 8 cases of rectourethral fistula treated at our institution in the last seven years. Seven of the patients underwent repair of the fistula using the modified York-Mason procedure. RESULTS: The causes of the fistula were radical retropubic prostatectomy in five patients, perineal debridement of Fournier's gangrene in one, transvesical prostatectomy in one and transurethral resection of the prostate in the other patient. The most common clinical manifestation was fecaluria, present in 87.5% of the cases. The mean time elapsed between diagnosis and correction of the fistula was 29.6 (7-63 months. One spontaneous closure occurred after five months of delayed catheterization. Urinary and retrograde urethrocystography indicated the site of the fistula in 71.4% of the cases. No patient presented recurrence of the fistula after its correction with the modified York-Mason procedure. CONCLUSION: The performance of routine colostomy and cystostomy is unnecessary. The technique described by York-Mason permits easy access, reduces surgical and hospitalization times and presents low complication and morbidity rates when surgically correcting recto-urethral fistulas.OBJETIVO: As fístulas reto-uretrais são de acesso difícil e por vezes complexo, sendo seu fechamento espontâneo raro.

Rectovaginal fistula (RVF) refers to a pathological passage between the rectum and vagina, which is a public health challenge. This study was aimed to explore the clinical value of endoluminal biplane ultrasonography in the diagnosis of rectovaginal fistula (RVF). Thirty inpatients and outpatients with suspected RVF from January 2006 to June 2013 were included in the study, among whom 28 underwent surgical repair. All 28 patients underwent preoperative endoluminal ultrasonography, and the obtained diagnostic results were compared with the corresponding surgical results. All of the internal openings located at the anal canal and rectum of the 28 patients and confirmed during surgery were revealed by preoperative endosonography, which showed a positive predictive value of 100 %. Regarding the 30 internal openings located in the vagina during surgery, the positive predictive value of preoperative endosonography was 93 %. The six cases of simple fistulas confirmed during surgery were revealed by endosonography; for the 22 cases of complex fistula confirmed during surgery, the positive predictive value of endosonography was 90 %. Surgery confirmed 14 cases of anal fistula and 14 cases of RVF, whereas preoperative endoluminal ultrasonography suggested 16 cases of anal fistula and 12 cases of RVF, resulting in positive predictive values of 92.3 and 93 %, respectively. The use of endoluminal biplane ultrasonography in the diagnosis of RVF can accurately determine the internal openings in the rectum or vagina and can relatively accurately identify concomitant branches and abscesses located in the rectovaginal septum. Thus, it is a good imaging tool for examining internal and external anal sphincter injuries and provides useful information for preoperative preparation and postoperative evaluation

Despite numerous modifications of surgical technique, pancreatic fistula remains a serious problem and occurs in about 10% of patients following pancreas resection. BioGlue is a new sealant that creates a flexible mechanical seal within minutes independent of the body's clotting mechanism. Application of BioGlue sealant will reduce the incidence of pancreatic fistula following pancreas resection. A retrospective cohort study was performed with 64 patients undergoing pancreas resection. BioGlue sealant was applied to the pancreatic anastomosis (Whipple) or resection margin (distal pancreatectomy) in 32 cases. Factors that could affect the rate of postoperative pancreatic fistula were recorded. Pancreatic fistula was defined as greater than 50 ml of drain output with an amylase content greater than three times normal serum value after postoperative day 10. To improve the sensitivity of our study, we also examined pancreatic fistula with a strict definition of any drain output on or after postoperative day 3 with a high amylase content and graded the fistulas in terms of clinical severity. Grade A leaks were defined as subclinical. Grade B leaks required some response such as making the patient nil per os, parenteral nutrition, octreotide, antibiotics, or a prolonged hospital stay. Grade C leaks were defined as serious and life threatening. They were associated with hemorrhage, sepsis, resulted in deterioration of other organ systems, and mandated intensive care. Comparisons between the two groups were made using the chi-square test or Fisher's exact test for categorical variables and by the Wilcoxon rank-sum test for continuous variables. P values of 0.05 or less were deemed statistically significant. There were no differences between the patients who received BioGlue and the control cohort in terms of comorbid conditions, tumor location, texture of the pancreas, size of the pancreatic duct, or surgical technique. By the common definition, pancreatic fistula occurred

A Rare Complication of Composite Dual Mesh: Migration and Enterocutaneous Fistula Formation

Full Text Available Introduction. Mesh is commonly employed for abdominal hernia repair because it ensures a low recurrence rate. However, enterocutaneous fistula due to mesh migration can occur as a very rare, late complication, for which diagnosis is very difficult. Presentation of Case. Here we report the case of an enterocutaneous fistula due to late mesh migration in a mentally retarded, diabetic, 35-year-old male after umbilical hernia repair with composite dual mesh in 2010. Discussion. Mesh is a foreign substance, because of that some of the complications including hematoma, seroma, foreign body reaction, organ damage, infection, mesh rejection, and fistula formation may occur after implantation of the mesh. In the literature, most cases of mesh-associated enterocutaneous fistula due to migration involved polypropylene meshes. Conclusion. This case serves as a reminder of migration of composite dual meshes.

To investigate clinical aspects and a new operative method for resecting third branchial fistula. The clinical aspects of 4 patients with third branchial fistula were retrospectively analyzed. It is difficult to locate the inner orifice of fistula through neck path due to tiny diameter of inner orifice. The inner orifice could be found and closed effectively by inserting yellow zebra guidewire from sinus piriformis with gastroscope. The mucous membrane of sinus piriformis could not be damaged due to the soft pointed end of yellow zebra guidewire. 4 cases were treated successfully without pharyngeal fistula or recurrent laryngeal nerve injury. No recurrent infections were found in all cases with follows-up of 6-66 months. Ineffectiveness of radiography with meglumine diatrizoate or oral administration of methylene blue before operation indicates tiny fistula. In this case, resection of third branchial fistula with the assistance of gastroscope and yellow zebra guidewire under general anesthesia can be performed. This innovative method of diagnosis and treatment is worth of application clinically.

To explore women's expectations, worries, and hopes related to returning to their family and community after fistula repair. We used a concurrent mixed methods design with a hospital survey and qualitative interviews. One hundred fifty-one women completed a questionnaire, eight were interviewed in hospital after fistula repair, and one woman was followed up at home for six months during the reintegration phase. Women were concerned about where they could live and about not being accepted by their husbands and in-laws. While 51% feared that their husbands would not accept them despite full recovery, 53% said their parents would accept them. In the qualitative study women wished to live with their parents, whereas almost one half (49.7%) of the women in the quantitative study, who had lived with fistula for a shorter time, wished to live with their husbands. All women hoped to have children in the future, although many women, especially those with no children, were worried about whether they could bear children in the future. Despite fears related to economic survival and social acceptance, women were optimistic about regaining a normal social life. Women's expectations of going home after fistula repair are linked to their history of living with obstetric fistula. For women who have lived with a fistula for many years, reintegration involves re-establishing an identity that is clean and respected. To facilitate this transition, fistula repair needs to be accompanied by psychological and social rehabilitation and assistance in returning to reproductive capabilities.

106 patients with inoperable malignant tumours constricting the central bronchial tree underwent endobronchial small-field radiotherapy with iridium-192 at high dose between June 1983 and September 1985. Treatment was performed using the computer-guided after-loading technique and a flexible bronchoscope under local anaesthesia. In complete occlusion of a bronchus by the tumour, a neodymium YAG-laser was applied (57 patients) to allow insertion of the afterloading probe. Endoscopy showed tumour regression in 75% of the patients, accompanied by clinical improvement. Pulmonary function tests, arterial blood gas analyses and pulmonary perfusion scans yielded a highly significant improvement of data after treatment. The procedure also proved effective upon exhaustion of external radiation. Apart from its positive palliation, endobronchial small-field radiotherapy using high doses of iridium-192 also has a curative effect, thus opening up a new approach to the therapy of advanced bronchial carcinoma.

Sorenson, Thomas J; La Pira, Biagia; Hughes, Joshua; Lanzino, Giuseppe

2017-08-01

Dural arteriovenous fistulas (DAVFs) of the craniocervical junction are uncommon vascular lesions, which often require surgical treatment even in the endovascular era. Most commonly, the fistula is placed laterally, and surgical ligation is performed through a lateral suboccipital craniotomy. After dural opening, the area is inspected, and the arterialized vein is identified emerging from the dura, often adjacent to the entry point of the vertebral artery, and ligated. A far lateral craniotomy is the authors' preferred surgical approach for accessing and treating dural arteriovenous fistulas of the craniocervical junction that cannot be reached endovascularly.

Acute suppurative neck infections associated with third or fourth branchial arch fistulas are frequently recurrent. Third and fourth branchial arch anomalies are much less common than those of second arch and usually present with left thyroid lobe inflammation. The authors present their experience with 15 cases of pyriform sinus fistulae (PSF) of third branchial arch origin and 3 cases of fourth arch origin, all of which presented as recurrent neck infection mainly on the left side. A retrospective review of 18 cases of third and fourth arch fistulae treated at JIPMER from 2005 to 2010. This study includes 18 patients with PSF diagnosed by the existence of fistulous tract radiologically and intraoperatively with pathological correlation. Neck exploration with excision of tract and left hemithyroidectomy was performed in all cases. The patients consisted of 7 males and 11 females, and the ages ranged from 3 to 15 years. All of them presented with recurrent episodes of neck infection. Investigations performed include computed tomography (CT) fistulography, barium swallow and ultrasound which were useful in delineating pyriform sinus fistulous tract preoperatively. All cases were on the left side and the fistula was identified by barium swallow in 14 cases (80%), while intraoperative and pathologic confirmation of the tract was possible in all cases (100%). Neck exploration with an emphasis on complete exposure of the recurrent laryngeal nerve and exposure of the pyriform sinus opening to facilitate complete fistulous tract excision with left hemithyroidectomy was successful in all patients. A follow up period of 1-3 years showed no recurrence. Recurrent neck infection in a child should alert the physician to the possibility of an underlying pyriform sinus fistula of branchial origin and CT fistulography should be performed after the resolution of the neck infection to delineate the tract anatomically.

Benign bronchial stenosis is managed by surgical or bronchoscopic methods. Although surgical approach is definitive, it is technically demanding and is costlier than bronchoscopic treatment. Here, we report the case of a 27-year-old female patient with symptomatic benign bronchial stenosis of the left main bronchus. The stenosis was dilated successfully through a fibreoptic bronchoscope by electrocautery followed by balloon bronchoplasty and application of mitomycin-C. On follow up, there was no evidence of re-stenosis.

Radioaerosol inhalation lung scintigraphy in bronchial asthma

International Nuclear Information System (INIS)

Chiba, Takashi

1993-01-01

A study on obstructive changes in airways and mucociliary clearance in children and youth with bronchial asthma was performed. Radioaerosol inhalation lung scintigraphies using 99T c-human serum albumin (HSA) were applied to 50 children and youth with bronchial asthma. The deposition patterns of the radioaerosol and aerosol clearance curves were evaluated. Abnormal deposition patterns, which consisted of non-homogeneous distribution and/or hot spot formation, were likely to be seen in patients with asthmatic attacks at the time of measurements. However, a few asymptomatic patients also revealed abnormal deposition patterns. The deposition patterns were related to FEV 1.0 %, MMF, V 50 and V 25 , but especially to FEV 1.0 %. As an index of mucociliary clearance, β, the rate constant of the 99m Tc-HSA aerosol clearance curve, was introduced. β was significantly lower in patients with abnormal aerosol deposition patterns than in normal persons. β was also significantly lower in patients undergoing asthmatic attack at the time of the measurements than in asymptomatic patients. β correlated negatively with FEV 1.0 %, MMF, V 50 and V 25 , but especially with FEV 1.0 %. Although patients with long term affection or moderate-to-severe asthma tended to reveal abnormal deposition patterns and had low β values, these differences were not statistically significant. Radioaerosol inhalation lung scintigraphy with 99m Tc-HSA is useful for evaluating not only obstructive changes in the airways but also for evaluating mucociliary clearance in children with bronchial asthma.

Pancreatic fistulae are a major complication of distal pancreatectomy (DP). Some cases of severe pancreatic fistula require invasive procedures. There have been some reports concerning the effectiveness of pancreatic duct drainage through an endoscopic transpapillary approach for pancreatic fistulae. We herein present a case of a pancreatic fistula after DP that was successfully treated with percutaneous pancreatic duct drainage, which was performed using a combined percutaneous and endoscopic approach, named the "rendezvous technique". In our case, we performed distal pancreatectomy with celiac artery resection for a locally advanced pancreatic body cancer. On postoperative day (POD) 7, the drain amylase level increased up to 37,460 IU/l. Computed tomography (CT) revealed peripancreatic fluid collections. On POD 10, we placed a catheter in the main pancreatic duct using the rendezvous technique. CT on POD 14 revealed a decrease in the size of the peripancreatic fluid collection, and contrast imaging from the drains on POD 22 revealed almost complete disappearance of the fluid collection. We withdrew the pigtail catheter on POD 27 and the percutaneous pancreatic duct drain on POD 36. This patient was discharged from our hospital on POD 40. We herein report a new approach called the "rendezvous technique" for the management of pancreatic fistulae after DP that can be used instead of a stressful nasopancreatic tube.

Scrotales fistulas are rare and often represent secondary lesions of tuberculosis. Mucinous adenocarcinomas are tumors containing at least 50% of extracellular mucus. They occur most commonly in the rectosigmoid; scrotal location is rare. We report the case of a 54-year old patient, with no particular past medical history, with secondary mucinous adenocarcinoma of the scrotum revealed by scrotal fistulas. The patient had suffered from recurrent scrotal fistulas for two years, with no other associated signs. Clinical examination showed multiple scrotal fistulas with discharge of thick pus. Rectal examination was normal. Urological examinations (IVU, UCRM, cystoscopy, …) were normal, the assessment of infectious diseases as well as the detection of BK virus in urine and sputum were negative. Biopsy of sample of scrotal tissue was in favor of moderately differentiated mucinous adenocarcinoma. Immunohistochemical examination was in favor of primary colorectal cancer. Patient's evolution was marked by the occurrence of complex anal fistulas, which appeared on MRI as active, supplying several pelvic peritoneal collections resulting in fleshy buds. There is no consensus on the therapeutic approach due to the rarity of this cancer. Surgical resection is the treatment of choice for this disease. Preoperative chemotherapy and radiation therapy are recommended for this type of cancer, but their role is not well established. The patient underwent primary neoadjuvant chemotherapy and radiation therapy, before abdominoperineal excision.

We report a case in a neonate of concurrent bronchial atresia and bronchogenic cyst. An accurate, noninvasive, preoperative diagnosis of this unusual combination of anomalies was made by ultrafast computed tomography (UFCT). This case supports the hypothesis that bronchial atresia results from an event occurring in the 5th-6th week of embryological development, rather than after the 16th week as previously believed.

Huang, Dong-e; Guo, Jian-hong; Lin, Ying

2010-02-01

Based on the retrieval of literatures in recent fifteen years, the time factors in the acupoint sticking therapy for the bronchial asthma are analyzed and compared in terms of the stage classification of patients, timing selection of acupoint sticking therapy and medication application, and times of application. The acupoint sticking therapy is mostly practiced during remittent stage of bronchial asthma; the timing selection is mostly during the hottest period of summer, the timing selection in certain cases is the coldest period of winter or any day; the duration of medication application is not consistent; therefore, the effectiveness of these cases is different. It may be that the ef fectiveness is proportional to the times and courses of acupoint sticking therapy for the bronchial asthma. In the future, the scientific designs which involve time factor are needed to elucidate the importance of time factor in acupoint sticking therapy for the bronchial asthma.

Background: Although cleft lip and cleft palate are among the most common congenital malformations, the presence of an isolated congenital palatal fistula along with a submucous cleft is very rare. This appears as an oval-shaped, full-thickness fenestration in the palatal midline that does not fully extend anteriorly or posteriorly, accompanied by the findings of a submucous cleft. Because of the uncommon nature of this entity, there is controversy about its etiology, diagnosis, and management. Methods: Two cases of children with congenital palatal fistulae and a submucous cleft palate are presented who were treated in different settings by different surgeons. Cases are discussed along with a thorough review of the available literature. Results: Patient 1 presented at 4 years of age with “a hole in the palate” since birth and abnormal speech. His palatal fistula and submucous cleft were repaired with a modified von Langenbeck technique in Ethiopia. At a 2-year follow-up, the palate remained closed, but hypernasal speech persisted. Patient 2 was a 1-year-old presenting with failure to thrive and nasal regurgitation, who underwent a Furlow palatoplasty in the United States with good immediate results. She was unfortunately lost to follow-up. Conclusions: A congenital fenestration of the palate is rare. Reports reveal suboptimal speech at follow-up, despite various types of repair, especially when combined with a submucous cleft. Available literature suggests that repair should not focus on fistula closure only but instead on providing adequate palate length to provide good velopharyngeal function, as in any cleft palate repair.

Purpose: To compare the rectal and prostatic radiation doses for a prospective series of 503 patients, 44 of whom developed persistent rectal bleeding, and 2 of whom developed rectal-prostatic fistulas. Methods and Materials: The 503 patients were randomized and treated by implantation with 125 I vs. 103 Pd alone (n = 290) or to 103 Pd with 20 Gy vs. 44 Gy supplemental external beam radiotherapy (n = 213) and treated at the Puget Sound Veterans Affairs Medical Center (n = 227), Schiffler Cancer Center (n 242) or University of Washington (n = 34). Patients were treated between September 1998 and October 2001 and had a minimum of 24 months of follow-up. The patient groups were treated concurrently. Treatment-related morbidity was monitored by mailed questionnaires, using standard American Urological Association and Radiation Therapy Oncology Group criteria, at 1, 3, 6, 12, 18, and 24 months. Patients who reported Grade 1 or greater Radiation Therapy Oncology Group rectal morbidity were interviewed by telephone to clarify details regarding their rectal bleeding. Those who reported persistent bleeding, lasting for >1 month were included as having Grade 2 toxicity. Three of the patients with rectal bleeding required a colostomy, two of whom developed a fistula. No patient was lost to follow-up. The rectal doses were defined as the rectal volume in cubic centimeters that received >50%, 100%, 200%, or 300% of the prescription dose. The rectum was considered as a solid structure defined by the outer wall, without attempting to differentiate the inner wall or contents. Results: Persistent rectal bleeding occurred in 44 of the 502 patients, 32 of whom (73%) underwent confirmatory endoscopy. In univariate analysis, multiple parameters were associated with late rectal bleeding, including all rectal brachytherapy indexes. In multivariate analysis, however, only the rectal volume that received >100% of the dose was significantly predictive of bleeding. Rectal fistulas occurred

To evaluate the preoperative diagnostic concordance of morphologic classification of anorectal fistula by endoanal ultrasonography (EUSG) and endoanal magnetic resonance imaging (EMRI). Between January 1998 and March 1999, 17 patients with anorectal fistula underwent endoanal ultrasonography and magnetic resonance imaging for preoperative assessment. The types of fistula and abscess formation were evaluated, and the findings compared with those obtained during surgery. The overall accordance of anorectal fistula was 76% (13 of 17 cases) on ultrasonography and 94% (16 of 17 cases) on magnetic resonance imaging. According to the findings of EUSG, the accordance of each type of anorectal fistula was as follows: transphineteric, 92% (11 of 12 cases); suprasphinteric, 33% (1 of 3); and extrasphincteric, 50% (1 of 2), while for EMRI, the respective figures were 100% (12 of 12 cases), 67% (2 of 3), and 100% (2 of 2). An analysis of reproducibility using kappa value showed that overall concordance between endoanal ultrasonography and surgery (κ=0.820) as well as between endoanal MRI and surgery (κ=0.866), was very close. For the evaluation of anorectal fistula, preoperative endoanal magnetic resonance imaging was more accurate and informative than endoanal ultrasonography

Obstetric fistula is a worldwide problem that is devastating for women in developing countries. The cardinal cause of obstetric fistula is prolonged obstructed labour and delay in seeking emergency obstetric care. Awareness about obstetric fistula is still low in developing countries. The objective was to assess the awareness about risk factors of obstetric fistulae in rural communities of Nabitovu village, Iganga district, Eastern Uganda. A qualitative study using focus group discussion for males and females aged 18-49 years, to explore and gain deeper understanding of their awareness of existence, causes, clinical presentation and preventive measures for obstetric fistula. Data was analyzed by thematic analysis. The majority of the women and a few men were aware about obstetric fistula, though many had misconceptions regarding its causes, clinical presentation and prevention. Some wrongly attributed fistula to misuse of family planning, having sex during the menstruation period, curses by relatives, sexually transmitted infections, rape and gender-based violence. However, others attributed the fistula to delays to access medical care, induced abortions, conception at an early age, utilization of traditional birth attendants at delivery, and some complications that could occur during surgical operations for difficult deliveries. Most of the community members interviewed were aware of the risk factors of obstetric fistula. Some respondents, predominantly men, had misconceptions/myths about risk factors of obstetric fistula as being caused by having sex during menstrual periods, poor usage of family planning, being a curse.

Full Text Available Tracheobronchomegaly(Mounier–Kuhn syndrome is dilatation of the trachea and major bronchi because of atrophy or absence of elastic fibers and smooth muscle cells .Patients presenting to primary care physician with lower respiratory tract symptoms like dyspnoea and wheezing are often diagnosed with COPD or asthma and started on treatment. There are uncommon conditions like Mounier-Kuhn syndrome (MKS that can present with similar symptoms and it is important for the primary care physician to keep them in mind when evaluating the patients. It is important to identify MKS, as early recognition can lead to better management and prevention of complications. Very few cases of MKS with Bronchial Asthma have been reported so far. We present a case of 65 year old male who presented with intermittent episodes of cough with productive sputum ,wheezing and breathing difficulty since last 35 years and was treated for Bronchial Asthma since last 25 years. He was later diagnosed with Mounier–Kuhn syndrome with Bronchial Asthma by clinical history supported by Radiological evidences.

With the recent introduction and development of the detachable balloon system, it has become the treatment of choice in the management of carotid cavernous fistulas(CCFs). But, since most delivery systems for embolization of CCF mainly depend on flow guidance for balloon delivery, in case of small fistula, pseudo aneurysm and arterialized venous collaterals, failure of balloon embolization can occur. To overcome these limitation, the authors designed and used a new versatile, steerable, and flow-guided detachable balloon system by using a Tracker catheter system with silicone or latex balloons. Using this maneuver, we could get successful fistula occlusion in 7 out of 8 patients (silicone balloon). But in one case, we had to occlude the internal carotid artery at the fistula site, proximal and distal cervical portions of the internal carotid artery. This balloon delivery system proved to provide high selectivity for fistula and relatively ease of handing

The misfortunate incident of formation of a urogenital fistula remains a major challenge for surgical urologists worldwide. Such fistulae may not be a life-threatening problem, but surely the women face demoralization, social boycott and even divorce and separation. The fistula may be vaginal, recto-vaginal or a combination of the two. The World Health Organization (WHO) has estimated that in the developing nations, nearly 5 million women annually suffer severe morbidity with obstetric fistulae being the foremost on the list. The objective of our study was to enunciate the patient demography, patient profile, incidence, type of surgery, as well as the long-term outcomes encountered in the management of all types of genital fistulae at a tertiary care centre. 50 consecutive patients, attending the outpatient department with urogenital fistulae, were studied during the period of 5 years from July 2005 to July 2009. All female patients with complaints of urinary incontinence and fecal incontinence and dribbling, patients having a history of obstructed labor, radiotherapy, instrumental delivery, foreign body or trauma and with a history of hysterectomy (abdominal/ vaginal) and lower segment caesarean section (LSCS) were included. A thorough urological examination included a dye study using methylene blue, Renal function tests, X-ray KUB and intravenous urography (IVU). Cystoscopy along with examination under anaesthesia (EUA) were done to assess the actual extent of injury. All patients were subjected to appropriate surgical interventions via the same combination of surgeons . Post operatively, prophylactic antibiotics were administered to all patients and patients were managed till discharge and followed thereafter via regular outpatient visits for a period of 3 years. Age of patients ranged from 21 to 40 years. 64% patients hailed from rural areas, 76% were from the lower socio-economic strata, 40% illiterate and 69% were short Statured.

Although much has been written on methods of dealing with pharyngocutaneous fistulas once they have formed, there are few reports of methods of preventing fistula formation from occurring. We examined the use of laser-weld techniques with the neodymium:yttrium aluminum garnet (Nd:YAG) and diode lasers to seal pharyngotomy closures. Laser-weld techniques have been used successfully in many other tissues, but reports documenting use in the upper aerodigestive tract are minimal. Indocyanine-green dye-enhanced collagen and fibrinogen were studied as laser solder materials for the diode laser. Twenty-nine experimental animals were studied. Neither the Nd:YAG nor the diode laser was successful in preventing fistula formation. Tensiometric studies documented significant strength of the laser welds ex vivo, but this finding was not clinically significant.
