    A 59 year-old patient was admitted with upper gastrointestinal bleeding. The clinical exam showed mild hypotension and blood samples revealed acute anemia (hemoglobin = 7.5 g/dl). Emergency computed tomography showed an infrarenal abdominal aortic aneurysm and extravasation of the arterial contrast material toward the digestive tract. The patient was transported to the operating room for emergency laparotomy, which showed an aortoduodenal fistula. After proximal and distal aortic vascular control, the two anatomical structures were dissected with duodenorrhaphy, patch repair of the aortic tear and omentum interposition. The postoperative recovery was uneventful, with discharge after 12 days. PMID:27737411

    Primary aorto-duodenal fistula (PADF) is a rare condition that may result in rapid exsanguination if untreated. PADF due to radiotherapy appears to be extremely rare with only a few cases reported in the medical literature. We report the case of a 61-year-old man who presented with massive gastrointestinal bleeding 25 years after surgery and radiotherapy for seminoma of the testicle and was successfully treated at our institution. We also review the literature on this very uncommon condition. A Medline search was conducted for the period from 1966 to June 2006 to identify case reports of PADF following radiotherapy. Only 7 cases of PADF due to radiotherapy were identified in addition to our own, 4 males and 3 females, aged 40 to 73 years, all treated for various forms of abdominal malignancies. The latency period ranged from 2 weeks to 25 years. None of the aortas were aneurysmatic. One patient died before he could be taken to the operating room. 5 patients underwent surgical repair and 4 survived. 2 patients underwent endovascular treatment but did not survive. PADF may develop up to 25 years after radiotherapy. Diagnosis should be considered when massive upper gastrointestinal bleeding develops in a patient who had previous abdominal radiotherapy, no matter how long before the episode of bleeding. Prompt surgical repair offers a reasonable chance of cure. Endovascular procedures do not appear to be efficacious. PMID:21897792

    Aortoenteric fistula (AEF) is an uncommon source of upper gastrointestinal (GI) tract hemorrhage, commonly occurring in persons with previous aortic surgery. Non-surgery related AEFs (primary AEFs) may occur in association with atherosclerotic lesions, infections, malignancies, or, rarely, result from penetrating/eroding foreign bodies. Given its rarity, primary AEF is not commonly considered in the pathologist's preliminary list of differential diagnoses at the commencement of an autopsy; however, the use of postmortem cross-sectional imaging may allow for the identification of primary AEF as a reasonable differential diagnoses prior to conventional autopsy. The current case outlines the forensic presentation, postmortem computed tomography (PMCT) features, and autopsy findings of a recent case of primary AEF resulting in lethal gastrointestinal hemorrhage. In such cases, PMCT features supporting primary AEF as the underlying cause of death include an atherosclerotic aneurysm abutting a segment of the GI tract with no definite soft tissue plane of separation, luminal GI contents of similar radiographic density to the aortic contents, lack of previous aortic surgery, and lack of a competing explanation for GI hemorrhage or a competing cause of death. Deaths from massive enteric hemorrhage without a medical history to suggest an underlying cause for the hemorrhage would fall under medicolegal jurisdiction and may, by examination of scene and circumstances alone, initially seem suspicious. This case demonstrates how PMCT could be used by a team of expert forensic radiologists and forensic pathologists to rapidly feedback vital information on the cause and manner of death to the criminal justice system.

    The aortoduodeonal fistula is a rare condition and has high mortality. We report five retrospective cases of digestive hemorrhage due to an aortoduodenal fistula (4 secondary and 1 primary) between 1986 and 1990. Three of them died. Attention is called to the importance of clinical suspicion and the main diagnostic methods in early diagnosis such as oral endoscopy. We also enhance the importance of emergency surgery for survival.

    Secondary aortoenteric fistula (SAEF) is a rare, life-threatening complication of aortic reconstructive surgery. Graft excision associated with gut repair and extra-anatomic bypass or in situ aortic reconstruction is the best option. However, it is associated with high mortality rates, especially when undertaken in unstable patients with severe comorbidities. We present a case of SAEF successfully treated by endovascular repair and gut restoration. After laparotomy, a dense inflammatory "frozen" mass was found around the involved part of the duodenum and the aortic sac. Because of his comorbidities, the difficulty in dissection of the aortic sac and the risk of damage in adjacent organs, the initial plan for aortic reconstruction was abandoned. A surgical isolation of the third portion of the duodenum and a duodenum-jejunal anastomosis were performed. An Endurant endograft 32-16-16 mm (Medtronic, Inc., Minneapolis, MN) was implanted to achieve aortic continuity. Twenty months postdischarge, the patient remains in good general condition, afebrile, and with normal laboratory tests and inflammation markers. In high-risk patients, endovascular intervention combined with gut repair without further aortic reconstruction can be a permanent solution requiring, however, close surveillance. PMID:25780328

    On the basis of a case of aorto-duodenal fistula due to fissuration of a tuberculous sub-renal aneurysm, the authors review the difficult question of primary and secondary aorto-digestive fistulae. Primary fistulae are due to the rupture of an artheromatous or infectious aneurysm. The latter possibility must always be borne in mind. Aneurysms secondary to an aortic suture are more common in practice. There is also often a troublesome infectious element, requiring axillobifemoral bypass prior to treatment of the aneurism itself.

    Uretero-iliac fistula is a rare cause of frank haematuria. The aetiology of such fistula is commonly iatrogenic. We present a unique case of a primary aorto-iliac fistula in the absence of an aneurysm or arteriovenous malformation. The diagnosis was demonstrated by ureteroscopy and real-time retrograde ureterogram. Multiple arterial embolisation of the fistula had failed, and the patient underwent a successful ureterolysis and ligation of fistula. We demonstrate the diagnostic difficulties and treatment dilemma of such rare cause of haematuria.

    Objectives Primary teeth work as guides for the eruption of permanent dentition, contribute for the development of the jaws, chewing process, preparing food for digestion, and nutrient assimilation. Treatment of pulp necrosis in primary teeth is complex due to anatomical and physiological characteristics and high number of bacterial species present in endodontic infections. The bacterial presence alone or in association in necrotic pulp and fistula samples from primary teeth of boys and girls was evaluated. Material and Methods Necrotic pulp (103) and fistula (7) samples from deciduous teeth with deep caries of 110 children were evaluated. Bacterial morphotypes and species from all clinical samples were determined. Results A predominance of gram-positive cocci (81.8%) and gram-negative coccobacilli (49.1%) was observed. In 88 out of 103 pulp samples, a high prevalence of Enterococcus spp. (50%), Porphyromonas gingivalis (49%), Fusobacterium nucleatum (25%) and Prevotella nigrescens (11.4%) was observed. Porphyromonas gingivalis was detected in three out of seven fistula samples, Enterococcus spp. in two out of seven samples, and F. nucleatum, P. nigrescens and D. pneumosintes in one out of seven samples. Conclusions Our results show that Enterococcus spp. and P. gingivalis were prevalent in necrotic pulp from deciduous teeth in boys from 2 to 5 years old, and that care of the oral cavity of children up to five years of age is important.

    2016-01-01

    Aortoenteric fistulas (AEFs) are deadly, abnormal connections between the aorta and gastrointestinal (GI) tract. While secondary aortoenteric fistulas (SAEFs) are more common and arise after aortic reconstruction, primary aortoenteric fistulas (PAEFs) are generally caused by abdominal aortic aneurysms (AAAs). PAEFs may present with self-limited GI bleeds called “herald bleeds,” and the fistula often goes undiagnosed until patients undergo laparotomy for a massive GI bleed. We describe a case of a PAEF in a 79-year-old man with known AAA. Due to variable clinical presentations and the rarity of the condition, many patients with PAEF die before an accurate diagnosis is made. In interpreting computed tomography (CT) scans of AEFs, the role of the radiologist is critical in the management of PAEF patients. PMID:27725922

    Arteriovenous fistulas (AVFs) can be posttraumatic or congenital vascular malformations. In the initial arteriographic evaluation, chronic AVFs potentially can be confused with arteriovenous malformations (AVMs). The authors studied five patients with a single AVF and one patient with numerous AVFs. Three patients had undergone surgery for treatment of their AVFs, one patient had undergone isobutyl-2-cyanoacrylate (IBCA) embolization, and two patients had undergone no prior therapy. The AVFs recurred in the three patients who had undergone surgery and in the patient who had undergone IBCA embolization. All patients underwent ethanol embolization of their AVFs. Angiograms obtained immediately after embolization documented closure of all AVFs. At follow-up, none of the embolized lesions have recurred. The authors conclude that ethanol embolotherapy can cure these problematic lesions. Extreme caution, however, must be employed with the use of intravascular ethanol because nontarget embolization can potentially result in tissue devitalization. In this study, two patients developed a small focal area of skin necrosis that did not require skin grafting and healed with conservative management.

    A patient admitted for treatment of an aorto-iliac aneurism presented himself with swelling of the lower extremities and a low grade bruit over the abdomen continuous throughout systole and diastole. Aortography demonstrated the presence of a suspected ilio-caval fistula. Surgical treatment consisted of closure of the fistula and vascular replacement with an appropriate aorto-bifemoral prosthesis. Large statistics report an incidence of aortocaval fistula up to 4% in association with rupturing aortic aneurisms. The grave clinical signs and aortography confirm the diagnosis. Some of those may obstruct themselves spontaneously only to reopen at the time of operation as in the case reported. The greatest peroperatory problems with closure of those fistulae are pulmonary emboli by air and aneurismal contents. In our first case a temporary caval clip was placed as a part in the management of the lesion. PMID:525160

    Primary aortoenteric fistula (PAEF) is a rare but catastrophic cause of massive gastrointestinal bleeding. Diagnosis of PAEF is difficult to make and is frequently delayed without strong clinical suspicion. Timely surgical intervention is essential for patient's survival. We report on a case of an 86-year-old woman with no history of abdominal surgery, who presented with abdominal pain. Initially, computed tomography scan showed an intra-abdominal abscess, located anterior to the aortic bifurcation. However, she was discharged without treatment because of spontaneous improvement on a follow-up computed tomography scan, which showed a newly developed right common iliac artery aneurysm. One week later, she was readmitted due to recurrent abdominal pain. On the second day of admission, sudden onset of gastrointestinal bleeding occurred for the first time. After several endoscopic examinations, an aortoenteric fistula bleeding site was found in the sigmoid colon, and aortography showed progression of a right common iliac artery aneurysm. We finally concluded that intra-abdominal abscess induced an infected aortic aneurysm and enteric fistula to the sigmoid colon. This case demonstrated an extremely rare type of PAEF to the sigmoid colon caused by an infected abdominal aortic aneurysm, which has rarely been reported. PMID:24755749

    Aim. To evaluate the technical success and patency rates following primary cutting balloon angioplasty for venous stenoses in native dialysis fistulas. Methods. Forty-one patients (26 men, 15 women; age range 26-82 years, average age 59 years) underwent 50 (repeat procedures in 9 patients) primary cutting balloon (PCB) angioplasty procedures in three institutions by three primary operators. The indication was primary stenosis in 21 patients, recurrent lesions in 15, and immature fistulas in 5. A PCB was used alone in 17 cases, but was followed by a larger standard balloon in 33 cases. Follow-up included ultrasound, flow analysis and urea reduction ratio, and ranged from 2 to 30 months (mean 14 months). Results. The technical success rate was 98%. All procedures were relatively painless. Two PCBs burst and 4 leaked, but without causing any morbidity. Nineteen fistulas were still working at last follow-up. Primary patency rates at 6, 12, and 24 months using Kaplan-Meier analysis were 88%, 73%, and 34%, respectively, and the primary assisted patencies were 90%, 75%, and 50%, respectively. Conclusion. PCB angioplasty has high technical success and low complication rates. The long-term patency rates are favorable for PCB angioplasty and compare favorably with other series.

    Secondary aortoenteric fistula (SAEF) is a rare yet lethal cause of gastrointestinal bleeding and occurs as a complication of an abdominal aortic aneurysm repair. Clinical presentation may vary from herald bleeding to overt sepsis and requires high index of suspicion and clinical judgment to establish diagnosis. Initial diagnostic tests may include computerized tomography scan and esophagogastroduodenoscopy. Each test has variable sensitivity and specificity. Maintaining the hemodynamic status, control of bleeding, removal of the infected graft, and infection control may improve clinical outcomes. This review entails the updated literature on diagnosis and management of SAEF. A literature search was conducted for articles published in English, on PubMed and Scopus using the following search terms: secondary, aortoenteric, aorto-enteric, aortoduodenal, aorto-duodenal, aortoesophageal, and aorto-esophageal. A combination of MeSH terms and Boolean operators were used to device search strategy. In addition, a bibliography of clinically relevant articles was searched to find additional articles (Appendix A). The aim of this review is to provide a comprehensive update on the diagnosis, management, and prognosis of SAEF. PMID:26653698

  16. Primary aorto-esophageal fistula: Great masquerader of esophageal variceal bleeding.

    Kokatnur, Laxmi; Rudrappa, Mohan

    2015-02-01

    Aorto-esophageal fistula is a rare cause of upper gastrointestinal bleeding. Thoracic aneurysm, the most common cause of this condition, will slowly increase over time and can erode the wall of the aorta creating a fistula and leading to torrential bleeding. High clinical suspicion is required for timely diagnosis as common investigations routinely done for gastrointestinal (GI) bleeding, including esophagogastroduodenoscopy, fails to detect most cases. The classical triad of midthoracic pain, herald bleeding and fatal hematemesis described in this condition is seen in only one-third of cases. Physician should be wary of this condition, especially in elderly patients with uncontrolled GI bleeding and who are also at risk of thoracic aneurysm. Computed tomography angiogram detects most cases and emergent endovascular repair with stents controls the initial bleeding. Later, both the aorta and the esophagus are repaired and reconstructed in staged procedures. PMID:25722556

    Mycotic aortic aneurysms account for 1–3% of all aortic aneurysms. The management of this disease is controversial. Since open surgical repair is associated with high morbidity and mortality rates, endovascular aneurysm repair is an alternative treatment method with promising early and midterm outcomes, although its long-term durability is unknown. Secondary aortoenteric fistulas may occur iatrogenically after either aortic reconstructive surgery or endovascular repair. As the number of aneurysms managed with endovascular aneurysm repair has substantially increased, cases of aortoenteric fistulas referred for endovascular repair are augmented. We report the case of an aortoduodenal fistula manifested with duodenal perforation after staged endovascular and surgical treatment of a mycotic aortic aneurysm. PMID:27365559

    2012-09-01

    We present the laparoscopic management of genitourinary fistulae, mainly five types of fistulae, vesicovaginal, ureterovaginal, vesicouterine, rectourethral and rectovesical fistula. Vesicovaginal fistula (VVF) is mostly secondary to urogynecologic procedures in developed countries, abdominal hysterectomy being the main cause of this condition; they represent 84.9% of the genitourinary fistulae (1).Management has been described for this type of fistula, where low success rate (7-12%) has been reported. Ureterovaginal fistulas may occur following pelvic surgery, particularly gynecological procedures, or as a result of vaginal foreign bodies or stone fragments after shock wave lithotripsy, patients typically present with global and persistent urine leakage through the vagina, this causes patient discomfort, distress, and typically protection is used to stay dry, the initial management is often conservative but typically fails. Vesicouterine fistula is a rare condition that only occurs in 1 to 4% of genitourinary fistulas, the primary cause is low segment cesareansection, and clinically presents in three different forms, which will be described. Treatment of this type of fistulae has been conservative,with hormone therapy and surgery, depending on the presenting symptoms. Recto-urinary (rectovesical and rectourethral) fistulae (RUF) are uncommon and can be difficult to manage clinically. Although they may develop in patients with inflammatory bowel disease and perirectal abscesses, rectourethral fistula frequently result as an iatrogenic complication of extirpative or ablative prostate procedures. Rectovesical fistula usually develops following radical prostatectomy, and occurs along the vesicourethral anastomotic line or along the suture line of a posterior "racquet-handle" closure of the bladder. Conservative management consisting of urinary diversion, broad-spectrum antibiotics and parenteral nutrition is often initially attempted but these measures often fail

    Vascular access micro-calcification is a risk factor for cardiovascular morbidity and mortality in hemodialysis (HD) patients but its influence on vascular access patency is still undetermined. Our study aimed to determine the impact of arterial micro-calcification (AMiC) on the patency of vascular access in HD patients. One-hundred fourteen HD patients receiving arteriovenous fistula (AVF) operation were included in this study. During the operation, we obtained partial arterial specimen and performed pathological examination by von Kossa stain to identify AMiC. We compared primary unassisted AVF failure within 1 year between positive and negative AMiC groups, and performed Cox regression analysis for evaluating risk factor of AVF failure. The incidence of AMiC was 37.7% and AVF failure occurred in 45 patients (39.5%). The AVF failure rate within 1 year was greater in the positive AMiC group than those in the negative AMiC group (53.5% vs. 31.0%, p = 0.02). Kaplan-Meier analysis showed that the positive AMiC group had a lower AVF patency rate than the negative AMiC group (p = 0.02). The presence of AMiC was an independent risk factor for AVF failure. In conclusion, preexisting AMiC of the vascular access is associated with primary unassisted AVF failure in incident HD patients.

    Tracheoesophageal fistula (TEF) is a relatively rare congenital anomaly. Surgical intervention is required to establish esophageal continuity and prevent aspiration and overdistension of the stomach. Since the first successful report of thoracoscopic TEF repair in 2000, the minimally invasive approach has become increasingly utilized. The main advantages of the thoracoscopic technique include avoidance of a thoracotomy, improved cosmesis, and superior visualization of the anatomy and fistula afforded by the laparoscope׳s magnification.

    Recurrent tracheoesophageal fistula (TEF) is still difficult to diagnose and repair. In almost all cases, recurrence appears relatively soon after the primary surgery. We herein describe a case of recurrent TEF that appeared 10 years after the primary repair. At 2 years of age, the patient suffered from mental retardation due to encephalitis and developed a hiatus hernia with gastro-esophageal reflux. He underwent the repair of a hiatus hernia and fundoplication at 3 years of age. However, the hiatus hernia recurred 6 months after the operation. The patient suffered from recurrent pneumonia for 6 years after the appearance of the recurrent hiatus hernia. At 9 years of age, he was hospitalized frequently due to recurrent severe pneumonia. After admission at 9 years of age, an endoscopic study under general anesthesia was performed and revealed subglottic stenosis and a dilated esophagus with a recurrent hiatus hernia. Tracheotomy or laryngotracheal separation was first planned in order to improve his upper airway and facilitate the safer repair of the recurrent hiatus hernia. After laryngotracheal separation, the patient still suffered from severe pneumonia. In addition, a small volume of nutritional supplement was aspirated from the tracheostomy. Thus, recurrent TEF was suspected. Tests using dye under both esophagoscopy and bronchoscopy confirmed recurrent TEF. The fistula recurred in the cervical area because of the elevation of the esophagus due to the recurrent hiatus hernia. The fistula was surgically closed, with a sternothyroid muscle flap to prevent re-recurrence. At 4 months after this operation, the recurrent hiatus hernia was repaired. Thereafter, the patient's respiratory symptoms showed a dramatic improvement. The patient is now doing well and free from further recurrences of TEF and hiatus hernia at 2 years after the final operation. PMID:27589983

    ABSTRACT Vesicovaginal fistula is an abnormal communication between the bladder and vagina and represents the most frequent type of fistula in the urinary tract. The most common cause in Brazil is iatrogenic fistula, secondary to histerectomia. Classically these women present continuous urinary leakage from the vagina and absence of micturition, with strong negative impact on their quality of life. We present a case of totally continent vesicovaginal fistula, with a follow-up of 11 years with no complications. PMID:23579756

    Background: Magnetic resonance imaging (MRI) is highly accurate for the depiction of both the primary tract of fistula and abscesses, in patients with perianal disease. In addition, MRI can be used to evaluate the activity of fistulas, which is a significant factor for determining the therapeutic strategy. Objectives: This study aimed to determine the usefulness of diffusion-weighted (DW) MRI for assessing activity and visibility of perianal fistula. Patients and Methods: Fifty-three patients with 56 perianal fistulas were included in the current retrospective study. The T2-weighted imaging (T2WI) and DWMRI were performed and apparent diffusion coefficient (ADC) values of fistulas were measured. Fistulas were classified into two groups: only perianal fistulas and fistulas accompanied by abscess. Fistulas were also classified into two groups, based on clinical findings: positive inflammatory activity (PIA) and negative inflammatory activity (NIA). Results: Mean ADC value (mm2/s) of PIA group was significantly lower than that of NIA group, regarding lesions in patients with abscess-associated fistulas (1.371 × 10-3 ± 0.168 × 10-3 vs. 1.586 × 10-3 ± 0.136 × 10-3; P = 0.036). No statistically significant difference was found in mean ADC values between PIA and NIA groups, in patients with only perianal fistulas (P = 0.507). Perianal fistula visibility was greater with combined evaluation of T2WI and DWMRI than with T2WI, for two reviewers (P = 0.046 and P = 0.014). Conclusion: The DWMRI is a useful technique for evaluating activity of fistulas with abscess. Perianal fistula visibility is greater with combined T2WI and DWMRI than T2WI alone. PMID:26715982

    Enterovesical fistulae are difficult to demonstrate by conventional radiographic methods. Computed tomography (CT), a sensitive, noninvasive method of documenting the presence of such fistulae, is unique in its ability to outline the extravesical component of the primary disease process. Twenty enterovesical fistulae identified by CT were caused by diverticulitis (nine), carcinoma of the rectosigmoid (two), Crohn disease (three), gynecologic tumors (two), bladder cancer (one), cecal carcinoma (one), prostatic neoplasia (one), and appendiceal abscess (one). The CT findings included intravesical air (90%), passage of orally or rectally administered contrast medium into the bladder (20%), focal bladder-wall thickening (90%), thickening of adjacent bowel wall (85%), and an extraluminal mass that often contained air (75%). CT proved to be an important new method in the diagnosis of enterovesical fistulae.

    A case in which an infiltrating mucinous carcinoma developed within a suprasphincteric fistula-in-ano is presented. The diagnosis was suspected on biopsy and confirmed by repeat biopsy. The clinical and histological features of this case establish with certainty that the carcinoma arose within the fistula and was not a secondary manifestation of the tumour. It is suggested that this rare complication of chronic fistula-in-ano may be prevented by prompt expert management of complex primary fistula. Images Figure 1 PMID:2829151

    One hundred and nineteen patients with gastrointestinal fistulas were treated in the Massachusetts General Hospital, Boston, in the period from January 1960 to January 1970. None of these patients was hyperalimented. The mortality in this seris amounted to 15%; 78.2% of the patients had their fistulas closed. These results are correlated with primary disease, etiology, fistula output, fistula location, type of treatment, malnutrition, electrolyte disturbances and sepsis. In the discussion it is concluded that treatment based on sound surgical principles acquired in the past decades, with the support of modern techniques of intensive patient care, should considerably diminish mortality and improve closure rate.

    The authors report a study on 120 patients with anal fistula (111 males and 9 females). The average age was 44.3 years (median 44, SD +/- 14.807). 64.1% of patients had an intersphincteric fistula, 23.3% hanal transphincteric fistula, 1.6% a suprasphincteric fistula, 7.5% a horseshoe fistula and the 3.3% an extrasphincteric fistula. We treated 14 patients (11.66%) with direct surgical treatment. The other 106 had various types of treatment depending on the localisation and the involvement of the anorectal sphincter. We had 11 cases (9.1%) of complications, such as recurrence in 5 patients (4.1%) transitory incontinence in 2 cases (1.6%) and finally postoperative bleeding in 3 patients (2.5%). PMID:9324655

    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.

    The Fistula First Initiative has strongly encouraged nephrologists, vascular access surgeons, and dialysis units in the United States to make valiant efforts to increase fistula use in the hemodialysis population. Unfortunately, the rigid "fistula first" recommendations are not based on solid, current, evidence-based data and may be harmful to some hemodialysis patients by subjecting them to prolonged catheter dependence with its attendant risks of bacteremia and central vein stenosis. Once they are successfully cannulated for dialysis, fistulas last longer than grafts and require fewer interventions to maintain long-term patency for dialysis. However, fistulas have a much higher primary failure rate than grafts, require more interventions to achieve maturation, and entail longer catheter dependence, thereby leading to more catheter-related complications. Given the tradeoffs between fistulas and grafts, there is equipoise about their relative merits in patients with moderate to high risk of fistula nonmaturation. The time is right for definitive, large, multicenter randomized clinical trials to compare fistulas and grafts in various subsets of chronic kidney disease patients. Until the results of such clinical trials are known, the optimal vascular access for a given patients should be determined by the nephrologist and access surgeon by taking into account (1) whether dialysis has been initiated, (2) the patient's life expectancy, (3) whether the patient has had a previous failed vascular access, and (4) the likelihood of fistula nonmaturation. Careful clinical judgment should optimize vascular access outcomes and minimize prolonged catheter dependence among hemodialysis patients. PMID:21030576

    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

    Anal fistulae are common and debilitating; they are characterized by severe pain and discharge. They arise following infection near the anal canal, or as a primary event from an abscess in the abdomen, fistulating into the vagina or perianal skin. The term ‘cryptoglandular’ is given to abscesses arising from the anal glands. For many years, the treatment of choice was to lay open the fistula; however, this risks causing incontinence with potentially devastating consequences. Alternative surgical treatments include setons, fibrin glue, collagen plugs and flaps to cover the internal fistula opening. These have achieved varying degrees of success, as will be discussed. The present review also discusses anal fistulae in light of much recently published literature. Currently, anal fistulae remain challenging and require specialist expertise; however, new treatment options are on the horizon. PMID:22175058

    Objective: To evaluate the two year patency rate of functioning arteriovenous fistula. Methodology: This prospective case series study was conducted at Department of Urology, Jinnah Postgraduate Medical Centre, Karachi, from 1st January 2009 to 31st December, 2010. Patients were chosen for CBRC arteriovenous fistula at wrist and patients undergoing other types of vascular access or secondary fistula formation were excluded. Results:One hundred and eighty two patients underwent arteriovenous fistula formation. The mean ± SD age was 63 ± 13 years and there were 102 (56%) males and 80 (44%) females. 12.6% fistulae failed within first month without dialysis. The primary patency rate was 66.5% at three months and 57.7% at six months. Failing arteriovenous fistula was managed by new arteriovenous fistula in our series. 28.6% patients had redo arteriovenous fistula. This study demonstrated a poor outcome for fistulas in diabetic patients. Fifteen out of 23 (65.2%) who failed primarily were diabetics and out of these diabetics 13 (86.7%) failed in first three months. Infection and burst fistulae were found in nine (4.9%), pseudo aneurysm in 3.2%, fever 4.9%, peri-operative failure 0.55% and burst fistulae 3.2%. Conclusions: One-third of radiocephalic fistulas fail within two years. The outcome is worse for women and diabetic patients. This information may be useful in assessing and counseling patients with end-stage renal failure. Arteriovenous fistula is the better and ideal choice for haemodialysis. A Radiocephalic fistula in forearm seems to have better results as comparison to cubital fossa arteriovenous fistula. End to side anastomosis results are better than side to side anastomosis.

    Coronary artery fistula is an uncommon finding during angiographic exams. We report a case series of five patients with congenital coronary fistulas. The first patient was 56 years old and had a coronary fistula associated with a partial atrio ventricular defect, the second patient was 54 years old and had two fistulas originating from the right coronary artery with a severe atherosclerotic coronary disease, the third patient was 57 years old with a fistula originating from the circumflex artery associated with a rheumatic mitral stenosis, the fourth patient was 50 years old and had a fistulous communication between the right coronary artery and the right bronchial artery, and the last patient was 12 years old who had bilateral coronary fistulas draining into the right ventricle with an aneurismal dilatation of the coronary arteries. Angiographic aspects of coronary fistulas are various; management is controversial and depends on the presence of symptoms.

    Chyle fistula is a potentially devastating phenomenon that results from violation of the thoracic duct or right lymphatic duct in the neck, most commonly during radical neck dissection. It may impair nutrition, compromise and delay wound healing, and prolong hospitalization. In view of the morbidity produced by chyle leak discovered postoperatively and the lack of success of its management by aggressive surgical techniques, we have employed a different protocol for the past six years. It is based on careful intraoperative inspection of the neck for possibly chyle fistula, minimal but specific surgical handling of the damaged duct, and a postoperative nutritional program designed to reduce chyle formation and facilitate spontaneous closure. The nutritional element involves the use of medium chain triglycerides (MCT) that are easily ingested, rapidly absorbed, and readily metabolized directly into the portal venous system, bypassing the thoracic duct lymphatic system. During a four-year period, 1976 to 1980, 574 radical neck dissections were performed with only six chyle fistulas being detected postoperatively. All have been successfully treated by the protocol with no patients requiring reexploration. There have been no deaths owing to chyle fistula and no complications or side effects from the use of medium chain triglycerides.

    The aetiology of congenital coronary artery fistulas remains a challenging issue. Coronary arteries with an anatomically normal origin may, for obscure reasons, terminate abnormally and communicate with different single or multiple cardiac chambers or great vessels. When this occurs, the angiographic morphological appearance may vary greatly from discrete channels to plexiform network of vessels. Coronary arteriovenous fistulas (CAVFs) have neither specific signs nor pathognomonic symptoms; the spectrum of clinical features varies considerably. The clinical presentation of symptomatic cases can include angina pectoris, myocardial infarction, fatigue, dyspnoea, CHF, SBE, ventricular and supraventricular tachyarrhythmias or even sudden cardiac death. CAVFs may, however, be a coincidental finding during diagnostic coronary angiography (CAG). CAG is considered the gold standard for diagnosing and delineating the morphological anatomy and pathway of CAVFs. There are various tailored therapeutic modalities for the wide spectrum of clinical manifestations of CAVFs, including conservative pharmacological strategy, percutaneous transluminal embolisation and surgical ligation.

    Fistulas of the genitourinary tract have diverse anatomic locations, causes, and clinical features. They can involve the upper urinary tract (kidney, ureter), the lower urinary tract (bladder, urethra), or the female reproductive tract (vagina, uterus). Causes include infection, inflammatory disease, neoplasms, congenital conditions, trauma, and iatrogenic injury. Diagnosis of genitourinary tract fistulas usually requires radiologic studies performed with fluoroscopic or cross-sectional modalities. Fistulography is the most direct means of visualizing a fistula and should be considered when feasible (eg, cutaneous fistulas). Intravenous urography and pyelography or ureterography are mainstays of investigation of the upper tract. Likewise, voiding cystourethrography and urethrography are central to study of the lower tract. Cross-sectional techniques, in particular computed tomography, are increasingly useful for diagnosis and are considered the primary test in some cases. Radiologists should be familiar with the radiologic features of genitourinary tract fistulas for accurate diagnosis and treatment planning. Management approaches depend on the type of fistula, the degree of morbidity, and the overall functional status of the patient and vary from conservative observation to aggressive surgical repair.

    PurposeTo evaluate the usefulness of an approach through the radial artery distal to the arteriovenous anastomosis for salvaging nonmaturing radiocephalic arteriovenous fistulas.MethodsProcedures that fulfilled the following criteria were retrospectively reviewed: (1) autogenous radiocephalic fistulas, (2) fistulas less than 3 months old, (3) distal radial artery approach for salvage. From 2005 to 2011, a total of 51 patients fulfilling the above criteria were enrolled. Outcome variables were obtained from angiographic, clinical and hemodialysis records, including the success, complication, and primary and secondary patency rates.ResultsThe overall anatomical and clinical success rates for the distal radial artery approach were 96 and 94 %, respectively. The average procedure time was 36 {+-} 19 min. Six patients (12 %) experienced minor complications as a result of extravasations. No arterial complication or puncture site complication was noted. The postinterventional 6-month primary patency rate was 51 %, and the 6-month secondary patency rate was 90 %. When the patients were divided into a stenosed group (20 patients) and an occluded group (31 patients), there were no differences in the success rate, complication rate, or primary and secondary patency rates.ConclusionAn approach through the radial artery distal to the arteriovenous anastomosis is an effective and safe alternative for the salvage of nonmaturing radiocephalic arteriovenous fistulas, even for occluded fistulas.

  3. Modern management of anal fistula

    Ideal surgical treatment for anal fistula should aim to eradicate sepsis and promote healing of the tract, whilst preserving the sphincters and the mechanism of continence. For the simple and most distal fistulae, conventional surgical options such as laying open of the fistula tract seem to be relatively safe and therefore, well accepted in clinical practise. However, for the more complex fistulae where a significant proportion of the anal sphincter is involved, great concern remains about damaging the sphincter and subsequent poor functional outcome, which is quite inevitable following conventional surgical treatment. For this reason, over the last two decades, many sphincter-preserving procedures for the treatment of anal fistula have been introduced with the common goal of minimising the injury to the anal sphincters and preserving optimal function. Among them, the ligation of intersphincteric fistula tract procedure appears to be safe and effective and may be routinely considered for complex anal fistula. Another technique, the anal fistula plug, derived from porcine small intestinal submucosa, is safe but modestly effective in long-term follow-up, with success rates varying from 24%-88%. The failure rate may be due to its extrusion from the fistula tract. To obviate that, a new designed plug (GORE BioA®) was introduced, but long term data regarding its efficacy are scant. Fibrin glue showed poor and variable healing rate (14%-74%). FiLaC and video-assisted anal fistula treatment procedures, respectively using laser and electrode energy, are expensive and yet to be thoroughly assessed in clinical practise. Recently, a therapy using autologous adipose-derived stem cells has been described. Their properties of regenerating tissues and suppressing inflammatory response must be better investigated on anal fistulae, and studies remain in progress. The aim of this present article is to review the pertinent literature, describing the advantages and limitations of

    The aim of this study was to analyze the features of Crohn's anal fistulas and to evaluate the efficacy of seton treatment. In 119 patients with Crohn's disease, the incidence of anal fistula was 56% (67/119), with no significant difference in the incidence among patients with ileitis, colitis, and ileocolitis. "Intractable" anal fistulas were found in 17% of patients with ileitis, compared to 64% of those with colitis (P = 0.051) and 68% of those with ileocolitis (P = 0.014). Seton treatment, i.e., non-cutting, long-term seton drainage, was performed for 21 patients (5 with intersphincteric, and 16 with transsphincteric fistulas). In the 16-month follow up, 9 patients required redrainage for recurrent fistulous abscess, mainly because of progressive colorectal disease. Finally, a good result was obtained in 17 of the 21 patients (81%) and no recurrent fistulous abscess developed in the 8 patients in whom all setons were removed. Anal continence was preserved in all the patients. These results indicate that anal fistulas with Crohn's ileitis were cured more easily than those with colitis or ileocolitis, and that seton treatment was effective for intersphincteric fistula with multiple fistula openings and for transphincteric fistulas in patients exhibiting remission of intestinal Crohn's disease.

    Introduction Cholecystocolic fistula is a rare complication of gallbladder disease. Its clinical presentation is variable and nonspecific, and the diagnosis is made, mostly, incidentally during intraoperative maneuver. Cholecystectomy with closure of the fistula is considered the treatment of choice for the condition, with an increasingly reproducible tendency to the use of laparoscopy. Aim To describe the laparoscopic approach for cholecystocolic fistula and ratify its feasibility even with the unavailability of more specific instruments. Technique After dissection of the communication and section of the gallbladder fundus, the fistula is externalized by an appropriate trocar and sutured manually. Colonic segment is reintroduced into the cavity and cholecystectomy is performed avoiding the conversion procedure to open surgery. Conclusion Laparoscopy for resolution of cholecystocolic fistula isn't only feasible, but also offers a shorter stay at hospital and a milder postoperative period when compared to laparotomy.

    The purpose of this study was to evaluate the efficacy and safety of a new hydrodynamic percutaneous thrombectomy catheter in the treatment of thrombosed hemodialysis fistulas and grafts. Twenty-two patients (median age: 47 years; range: 31-79 years) underwent mechanical thrombectomy for thrombosed hemodialysis fistulas or polytetrafluoroethylene (PTFE) grafts. In all cases, an Oasis hydrodynamic catheter was used. Five patients had native fistulas and 17 had PTFE grafts. Six patients required repeat procedures. All patients with native fistulas and 15 of the 17 with PTFE grafts also underwent angioplasty of the venous limb following the thrombectomy. Major outcome measures included technical success, clinical success, primary and secondary patency, and complication rates. Twenty-eight procedures were performed in total. The technical success rate was 100% and 90% and clinical success was 86% and 76% for native fistulas and grafts, respectively. The primary patency at 6 months was 50% and 59% for fistulas and grafts, respectively, and the secondary patency at 6 months was 75% and 70% for fistulas and grafts, respectively. Two patients died of unrelated causes during the follow-up period. The Oasis catheter is an effective mechanical device for the percutaneous treatment of thrombosed hemodialysis access. Our initial success rate showed that the technique is safe in the treatment of both native fistulas and grafts.

    Purpose The purpose of this study was to determine the incidence of and risk factors for pharyngocutaneous fistula in patients undergoing total laryngectomy at a single institution. Materials and methods The records of 59 patients undergoing primary or salvage total laryngectomy at our institution from 2001 to 2012 were retrospectively reviewed. Data collected included patient, tumor and treatment characteristics, and surgical technique. Risk factors were analyzed for association with pharyngocutaneous fistula formation. Results Twenty patients (34%) developed fistulas. Preoperative tracheostomy (OR 4.1; 95% CI 1.3–13 [p = 0.02]) and low postoperative hemoglobin (OR 9.1; 95% CI 1.1–78 [p = 0.04]) were associated with fistula development. Regarding surgical technique, primary sutured closure of the total laryngectomy defect had the lowest fistula rate (11%). In comparison, primary stapled closure and pectoralis onlay flap over primary closure had nonsignificantly increased fistula rates (43%, OR 6.0; 95% CI 1.0–37.3 [p = 0.06] and 25%, OR 2.7; 95% CI 0.4–23.9 [p = 0.38], respectively). Pectoralis flap incorporated into the suture line had a significantly increased fistula rate (50%, OR 7.1; 95% CI 1.4–46 [p = 0.02]). After stratification for salvage status, patient comorbidities were associated with fistula in non-salvage cases whereas disease-related characteristics were associated with fistula in salvage cases. Fistula development was associated with increased length of hospital stay (p < 0.001) and increased time before oral diet initiation (p < 0.001). Conclusions Pharyngocutaneous fistula is a common complication of total laryngectomy. Preoperative tracheostomy, postoperative hemoglobin, and surgical technique are important in determining the risk of fistula. PMID:25245411

    Extraanatomical bypass has been advocated as the primary technique in adolescents or adults presenting with aortic coarctation. This approach carries significant morbidity, and graft-related complications may be more important in the young patient population. A 52-year-old man who had previously undergone extraanatomical bypass of aortic coarctation was diagnosed with a distal anastomotic pseudoaneurysm and aortoesophageal fistula. This was managed by proximal bypass plugging with an occluder, endovascular exclusion with a stent-graft in the thoracic descending aorta covering the pseudoaneurysm, and coarctation balloon dilation. Aortoesophageal fistula is a late complication observed after extraanatomical bypass for coarctation. This case illustrates this rare complication.

    To describe the etiology, anatomy and pathophysiology of rectovaginal fistulas (RVFs); and to describe a systematic surgical approach to help achieve optimal outcomes. A current review of the literature was performed to identify the most up-to-date techniques and outcomes for repair of RVFs. RVFs present a difficult problem that is frustrating for patients and surgeons alike. Multiple trips to the operating room are generally needed to resolve the fistula, and the recurrence rate approaches 40% when considering all of the surgical options. At present, surgical options range from collagen plugs and endorectal advancement flaps to sphincter repairs or resection with colo-anal reconstruction. There are general principles that will allow the best chance for resolution of the fistula with the least morbidity to the patient. These principles include: resolving the sepsis, identifying the anatomy, starting with least invasive surgical options, and interposing healthy tissue for complex or recurrent fistulas.

    A case of aortocaval fistula complicating a ruptured infrarenal aortic aneurysm is reported. As the length of the defect and the thickness of the aortic wall made repair from within the aorta unsafe, the defect was repaired from within the vena cava. The details of the technique are reported. It can be a useful alternative to inferior vena cava ligation, when standard repair of aortocaval fistulae from within the aorta is risky or difficult to attempt.

    Purpose: To review the place of interventional radiology in arteriovenous access for hemodialysis. Methods: Prophylactic dilation of stenoses greater than 50% associated with clinical abnormalities such as flow-rate reduction is warranted to prolong access patency. Stents are placed only in selected cases with clearly insufficient results of dilation but they must never overlap major side veins and obviate future access creation. Thrombosed fistulae and grafts can be declotted by purely mechanical methods or in combination with a lytic drug. Results: The success rates are over 90% for dilation, with frequent resort to stents in central veins. Long-term results in the largest series are better in forearm native fistulae compared with grafts (best 1-year primary patency: 51% versus 40%). The success rates for declotting are better in grafts compared with forearm fistulae but early rethrombosis is frequent in grafts so that primary patency rates can be better for native fistulae from the first month's follow-up (best 1-year primary patency: 49% versus 26%). Conclusion: Radiology achieves results comparable with surgery, with minimal invasiveness and better venous preservation. However, wide variations in the results suggest that the degree of commitment of physicians might be as important as the type of technique used.

    The digestive fistula is one of the most serious complications that might appear following different types of resectional digestive surgery. This condition still carries a considerable morbidity and mortality rate and therefore all surgical and ICU staff pay a great deal of attention and intensify their care to avoid the fatalities. The postoperative digestive fistulas, through their physiopathological and clinical complexity induce the disturbance of the biological equilibrium with vital consequences. The trend of the last decades is the increasing of digestive fistulas incidence with a variable mortality rate after different authors. A therapeutic algorithm is needed. The mortality rate due to digestive fistulas, two decades ago was, around 60%; at the present there is a decrease of the mortality rate, which is around 10%. The explanation is the introduction of the new methods of treatment such as lactic acid lavage aspiration for alkaline fistulas or total parenteral nutrition, continuous enteral nutrition and antiexocrine chemotherapy. A fistula is a communication between two epithelial or endothelial surfaces, lined by granulation tissue. It can be a life-threatening condition. PMID:21495307

    Uroenteric fistulae can occur between any part of the urinary tract and the small and large bowel. Classification is generally based on the organ of origin in the urinary tract and the termination of the fistula in the segment of the gastrointestinal tract. Surgery is often necessary. Congenital fistulae are rare, with most being acquired. Uroenteric fistulae most frequently occur in a setting of inflammatory bowel disease. Imaging often helps in the diagnosis. Management of urinary fistulae includes adequate nutrition, diversion of the urinary tract, diversion of the gastrointestinal tract, treatment of underling inflammatory process or malignancy, and surgery.

    ABSTRACT Objective: The purpose of this video is to present the laparoscopic repair of a VUF in a 42-year-old woman, with gross hematuria, in the immediate postoperative phase following a cesarean delivery. The obstetric team implemented conservative management, including Foley catheter insertion, for 2 weeks. She subsequently developed intermittent hematuria and cystitis. The urology team was consulted 15 days after cesarean delivery. Cystoscopy indicated an ulcerated lesion in the bladder dome of approximately 1.0cm in size. Hysterosalpingography and a pelvic computed tomography scan indicated a fistula. Materials and Methods: Laparoscopic repair was performed 30 days after the cesarean delivery. The patient was placed in the lithotomy position while also in an extreme Trendelenburg position. Pneumoperitoneum was established using a Veress needle in the midline infra-umbilical region, and a primary 11-mm port was inserted. Another 11-mm port was inserted exactly between the left superior iliac spine and the umbilicus. Two other 5-mm ports were established under laparoscopic guidance in the iliac fossa on both sides. The omental adhesions in the pelvis were carefully released and the peritoneum between the bladder and uterus was incised via cautery. Limited cystotomy was performed, and the specific sites of the fistula and the ureteral meatus were identified; thereafter, the posterior bladder wall was adequately mobilized away from the uterus. The uterine rent was then closed using single 3/0Vicryl sutures and two-layer watertight closure of the urinary bladder was achieved by using 3/0Vicryl sutures. An omental flap was mobilized and inserted between the uterus and the urinary bladder, and was fixed using two 3/0Vicryl sutures, followed by tube drain insertion. Results: The operative time was 140 min, whereas the blood loss was 100ml. The patient was discharged 3 days after surgery, and the catheter was removed 12 days after surgery. Discussion: Laparoscopy has

    Broadly, complex fistulas are those that are not low transsphincteric or intersphincteric. The objectives of surgical management are to achieve fistula healing, prevent recurrences and maintain continence. The risk of incontinence associated with treatment ranges from 10% to 57%. The objective of this manuscript is to review the current literature to date on the ligation of the intersphincteric fistula tract procedure (LIFT procedure) as a treatment option in these types of fistula. A search was conducted in Medline, PUBMED, EMBASE and ISI Web of Knowledge, and studies published from January 2009 to May 2013 were included. The primary outcomes were fistula healing rates, mean healing time and patient satisfaction with this surgical technique. Eighteen studies were included in this review. The total number of patients included was 592 (65% male). The median age reported was 42.8 years. The most common type of fistula included was transsphincteric (73.3% of cases). The mean healing rate reported was 74.6%. The risk factors for failure discovered were obesity, smoking, multiple previous surgeries and the length of the fistula tract. The mean healing time was 5.5 wk, and the mean follow-up period was 42.3 wk. The patient satisfaction rates ranged from 72% to 100%. No de novo incontinence developed secondary to the LIFT procedure. There is not enough evidence that variants in the surgical technique achieve better outcomes (Bio-LIFT, LIFT-Plug, LIFT-Plus). This review indicates that the LIFT procedure is primarily effective for transsphincteric fistulas with an overall fistula closure of 74.6% and has a low impact on fecal continence. This procedure produces better outcomes at the first surgical attempt.

    AIM: To compare the efficacy and safety of acellular dermal matrix (ADM) bioprosthetic material and endorectal advancement flap (ERAF) in treatment of complex anorectal fistula. METHODS: Ninety consecutive patients with complex anorectal fistulae admitted to Anorectal Surgical Department of First Affiliated Hospital, Xinjiang Medical University from March 2008 to July 2009, were enrolled in this study. Complex anorectal fistula was diagnosed following its clinical, radiographic, or endoscopic diagnostic criteria. Under spinal anesthesia, patients underwent identification and irrigation of the fistula tracts using hydrogen peroxide. ADM was securely sutured at the secondary opening to the primary opening using absorbable suture. Outcomes of ADM and ERAF closure were compared in terms of success rate, fecal incontinence rate, anorectal deformity rate, postoperative pain time, closure time and life quality score. Success was defined as closure of all external openings, absence of drainage without further intervention, and absence of abscess formation. Follow-up examination was performed 2 d, 2, 4, 6, 12 wk, and 5 mo after surgery, respectively. RESULTS: No patient was lost to follow-up. The overall success rate was 82.22% (37/45) 5.7 mo after surgery. ADM dislodgement occured in 5 patients (11.11%), abscess formation was found in 1 patient, and fistula recurred in 2 patients. Of the 13 patients with recurrent fistula using ERAF, 5 (11.11%) received surgical drainage because of abscess formation. The success rate, postoperative pain time and closure time of ADM were significantly higher than those of ERAF (P < 0.05). However, no difference was observed in fecal incontinence rate and anorectal deformity rate after treatment with ADM and ERAF. CONCLUSION: Closure of fistula tract opening with ADM is an effective procedure for complex anorectal fistula. ADM should be considered a first line treatment for patients with complex anorectal fistula. PMID:20614483

    Occasionally surgeons have to operate on patients who have had previous abdominal or pelvic operations and irradiations for malignancies. Bowel resection with primary anastomosis under these circumstances is fraught with major complications such as anastomotic breakdown with intra-abdominal sepsis or recurrent enterocutaneous fistula, which are refractory to conventional management. New techniques for using vascularized muscle flaps from a distant nonirradiated field to achieve safe repair of the bowel defects in three such instances are presented.

    Achieving Dialysis Outcomes Quality Initiative guidelines for native arteriovenous fistulae using the radiocephalic forearm fistula (lower-arm fistula [LAF]) is difficult. This study reports results using the upper-arm native arteriovenous fistula (UAF). From a prospective access database (1992 to 1998), this study was based on 204 patients (322 accesses). Average patient age was 56 +/- 1 years, 63% were men, and 47% had diabetes. A native fistula was the first access in 73% of patients (36%, LAFs; 37%, UAFs) and accounted for 48% of subsequent accesses (13%, LAFs; 35%, UAFs). Younger men were more likely to receive an LAF, but there was no demographic difference between patients receiving a UAF or arteriovenous graft (AVG). Both primary unassisted and cumulative access patencies were significantly better for UAFs than either LAFs or AVGs. For first accesses, cumulative access patency rates at 1, 3, and 5 years were 71%, 57%, and 57% for UAFs; 54%, 46%, and 36% for LAFs; and 54%, 28%, and 0% for AVGs (P < 0.01). Despite shorter access survival, AVGs required more total access procedures than either UAFs or LAFs (procedures per access: 2.5, 1.0, and 0.6 for AVGs, UAFs, and LAFs, respectively). When used, catheters were required for dialysis for a longer time for UAFs (median catheter days, 36, 53, and 56 for AVGs, LAFs, and UAFs, respectively; P < 0.05). Access flow rates were greater in UAFs (1,247 mL/min; n = 48; P < 0.01) than AVGs (851 mL/min; n = 30) or LAFs (938 mL/min; n = 31). There was no evidence that UAFs were banded or ligated for steal syndromes or heart failure more often than AVGs or LAFs. These results show that the UAF is a good alternative to an AVG for achieving Dialysis Outcomes Quality Initiative guidelines.

    The functional outcome of fistula surgery can be quantitated by anal manometry. A closed, water-filled microballoon (0.5 X 1.0 cm) system was used to measure resting anal pressure and maximal squeeze pressure in 47 patients with anal fistulas at St. Mark's Hospital. After treatment of intersphincteric fistulas, there was a significant reduction in resting pressure in the distal 2 cm. In treated transphincteric fistulas and suprasphincteric fistulas, anal pressure was reduced in the distal 3 cm. A significant lower pressure was measured in patients having the external sphincter divided, compared with those having the muscle preserved. Disturbance of continence was related to abnormally low resting pressure in six patients. This study supports attempts at sphincter preservation in fistula surgery. PMID:6825520

    Despite over 40 years of research there has been little progress in the prevention of obstetric fistula and women continue to suffer in unacceptable numbers. Gender power imbalance has consistently been shown to have serious implications for women's reproductive health and is known to persist in regions where obstetric fistula occurs. Yet, there is limited research about the role gender power imbalance plays in childbirth practices that put women at risk for obstetric fistula. This information is vital for developing effective maternal health interventions in regions affected by obstetric fistula.

    This report reviews a prospective database applying a systematic fistulomy technique in 101 patients requiring surgery for fistula in ano at LAC+USC Medical Center during a 15-month period. Data were collected for the reliability of primary crypt palpation, success of tract injection with peroxide/methylene blue, and the accuracy of Goodsall's rule. Time to healing, recurrence, and incontinence according to type of procedure were also recorded. Palpation of the primary crypt was possible in 93 per cent. Hydrogen peroxide/methylene blue injection successfully delineated the tract in 83 per cent. Goodsall's rule was correct in 81 per cent. Each fistula was categorized as intersphincteric (n = 72), transphincteric (n = 33), extrasphincteric (n = 1), or submucosal (n = 6). At a mean follow-up period of 44 weeks, 89.2 per cent of patients were cured. Reasons for recurrence included wound bridging (n = 6), misdiagnosis of the tract (n = 3), and two blind-ended fistulae (n = 2). Time to healing in weeks was (mean, range): simple fistulotomy (12, 3-21), seton (16, 4-28), Hanley procedure (28, 8-48). Patients with a marsupialized tract healed at an average of 6 weeks (range 4-8). Four (3.9%) patients reported postoperative incontinence (1 gas, 3 liquid, 0 solids). PMID:16494174

    Posttraumatic esophagomediastinal fistula is an uncommon clinical entity that warrants surgical awareness due to its life-threatening potential. Its management, especially in previously operated field, is controversial and several endoscopic methods are being proposed as alternatives. Ours is the first report of endoscopic fulguration and fibrin injection in successful closure of such fistula. A 9-year-old female sustained complete tracheoesophageal transection from a gunshot wound to the neck and underwent immediate primary repair. She presented nine months later with fevers and swelling over anterior neck. CT revealed air tracking posteriorly to the dorsal neck and inferiorly to the mediastinum. Considering difficulty of open surgical approach, endoscopic intervention was attempted. Posterior wall fistula was identified via microlaryngoscopy above the esophageal anastomosis. The fistula tract was de-epithelialized via a Bugbee fulgurating electrode and then sealed with fibrin glue. Consequent imaging studies demonstrated complete occlusion of the fistula. Posterior posttraumatic esophagomediastinal fistula presents a challenging scenario from a surgical standpoint, as it combines difficulty of safe approach, high rate of injury to surrounding structures, and significant postoperative recurrence rate. Endoscopic Bugbee fulguration and fibrin glue injection are a safe and effective alternative to the traditional approach. PMID:27670565

    Background: Secondary palatal fistula and velopharyngeal insufficiency (VPI) are two major complications of palatoplasty. Various methods have been introduced for surgical repair of these complications; however, most of them are associated with a high recurrence rate and morbidity. This study was designed to evaluate the use of the buccinator myomucosal flap in the reconstruction of palatal fistula and velopharyngeal insufficiency following primary palatoplasty. Materials and Methods: This study was performed on 25 patients who had either secondary palatal fistula or velopharyngeal insufficiency. Their defects were repaired by buccinator myomucosal flaps (BMFs). Patients were followed for 8 weeks and follow-up visits were arranged at 1, 2, 4, and 8 weeks after discharge. Results: All BMFs were harvested and transposed successfully. The length of the soft palate increased 15.14 ± 1.13 mm postoperatively. One patient (4%) had flap dehiscence 6 days after the operation with no flap ischemia or necrosis. Another patient (4%) experienced recurrence of the palatal fistula with marginal necrosis of the BMF 6 weeks after the operation. Otherwise, no case of fistula recurrence, infection, flap ischemia or necrosis and donor-site morbidity was observed during follow-up sessions. Conclusion: This study demonstrated that using BMFs could be a safe, effective and promising method of treatment for post palatoplasty fistula and VPI. However, further investigations on a larger sample size with longer follow-up are recommended for more accurate conclusion. PMID:26322283

    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.

    AIM: To evaluate accuracy of three-dimensional endoanal ultrasound (3D-EAUS) as compared to 2D-EAUS and physical examination (PE) in diagnosis of perianal fistulas and correlate with intraoperative findings. METHODS: A prospective observational consecutive study was performed with patients included over a two years period. All patients were studied and operated on by the Colorectal Unit surgeons. The inclusion criteria were patients over 18, diagnosed with a criptoglandular perianal fistula. The PE, 2D-EAUS and 3D-EAUS was performed preoperatively by the same colorectal surgeon at the outpatient clinic prior to surgery and the fistula anatomy was defined and they were classified in intersphincteric, high or low transsphincteric, suprasphincteric and extrasphincteric. Special attention was paid to the presence of a secondary tract, the location of the internal opening (IO) and the site of external opening. The results of these different examinations were compared to the intraoperative findings. Data regarding location of the IO, primary tract, secondary tract, and the presence of abscesses or cavities was analysed. RESULTS: Seventy patients with a mean age of 47 years (range 21-77), 51 male were included. Low transsphincteric fistulas were the most frequent type found (33, 47.1%) followed by high transsphincteric (24, 34.3%) and intersphincteric fistulas (13, 18.6%). There are no significant differences between the number of IO diagnosed by the different techniques employed and surgery (P > 0.05) and, there is a good concordance between intraoperative findings and the 2D-EAUS (k = 0.67) and 3D-EAUS (k = 0.75) for the diagnosis of the primary tract. The ROC curves for the diagnosis of transsphincteric fistulas show that both ultrasound techniques are adequate for the diagnosis of low transsphincteric fistulas, 3D-EAUS is superior for the diagnosis of high transsphincteric fistulas and PE is weak for the diagnosis of both types. CONCLUSION: 3D-EAUS shows a higher

    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.

    Background 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. Patients and methods 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. Results 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. Conclusions 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. PMID:22933919

    Bronchopleural fistula (BPF) produced by endotracheal suction catheter is a known cause of persistent pneumothorax in preterm infants in intensive care nurseries. This report describes the pulmonary pathology of a neonate who had sustained this injury. The observation suggests that the abnormal airflow results in severe damage of the involved lobe and an unusually mild bronchopulmonary dysplasia in the rest of the lung. This is in agreement with the fact that BPF acts as the path of least resistance for the oxygen-rich air from the ventilator.

    Injury to the thoracic duct, leading to chyle leak, occurs in 1-2,5% of patients who undergo neck dissection. Associated complications include malnutrition, immune compromise, fistula formation and carotid blowout. No definitive treatment algorithm can be deduced from the current literature, but on last reviews, there is an agreement on the conservative management. Medical management is based on that decreasing chyle flow will allow for spontaneous closure of the chyle leak. Conservative treatment includes: closed vacuum drainage, bed-rest, nutrition modification and synthetic somatostatin analog. Nutrition modification involves a low-fat diet supplemented with medium-chain triglycerides (MCT), enteral nutrition with high percentage of MCT or parenteral nutrition.

Maler in 1940 independently observed that loculated BPF pockets conform in shape to the adjacent chest wall. With the most common posterior costophrenic angle location, there is a wide air-fluid level in the frontal view, but on lateral films the anteroposterior diameter is narrow. In contrast, abscess cavities tend to be spherical and farther from the ribs. Use of these plain film criteria permits earlier and more confident diagnosis.

    A middle-age man presented with acute urinary retention and a history of passage of urine and stones through a fistula at the root of the penis of 7 years' duration. Computed tomography of the soft tissue penis revealed multiple calculi in the urethra. After an initial suprapubic cystostomy, he underwent Johanson's Stage I urethroplasty with excision of the fistulous tract and retrieval of the urethral stones. Intraoperatively, dense stricture of the distal penile urethra was found, with complete obliteration in places. A urethral stricture, if not promptly managed, can lead to devastating complications necessitating complex surgical management.

    Perforations, leaks and fistula involving gastrointestinal (GI) tract are increasing encountered in clinical practice. There is a changing paradigm for their management with surgical approach being replaced by conservative approach including endoscopic therapy. Clips (through the scope and over the scope) and covered stent are front runners for endotherapy for GI leaks and fistula. Over the scope clips introduced recently, can treat larger defects compared to through the scope clips. Covered stents are suited for larger defects and those associated with luminal narrowing. However cervical esophagus, gastro-esophageal junction, stomach and right colonic lesions may be better for clip therapy rather than stenting. Recent developments in this field include use of endovac therapy which consists of a sponge with suction device, biodegradable stent, use of fibrin glue and some endo-suturing device. Conservative therapy with no surgical or endoscopic intervention, may be suitable for a small subset of patients. An algorithm based on location, size of defect, associated stricture, infection and available expertise needs to be developed to reduce the mortality and morbidity of this difficult clinical problem.

    Over 2 million women worldwide have an obstetric fistula, with the majority of cases occurring in resource-poor countries. Afflicted women tend to be young, primiparous, impoverished, and have little or no access to medical care. Incontinent of urine and/or stool, these women become ostracized and shunned by their community. Most obstetric fistulas are surgically correctible, although surgical outcomes have been poorly studied. Programs that improve nutrition, delay the age of marriage, improve family planning, and increase access to maternal and obstetric care are necessary to prevent obstetric fistula. PMID:19173024

    Pneumobilia is the finding of air in the biliary tree. Most cases are iatrogenic in origin, especially after sphincterotomy and after hepaticojejunostomy or choledochojejunostomy. In patients without such history, the presence of pneumobilia needs further investigation. Most patients are likely to have an enterobiliary fistula. Although patients may be asymptomatic, possible complications include gallstone ileus, Bouveret syndrome or recurrent episodes of cholangitis. We present a case of a 38-year-old man presenting with obstructive jaundice and pneumobilia in whom choledochoduodenal fistula was diagnosed at endoscopic retrograde cholangiography. A description of different types of choledochoduodenal fistulas and management recommendations are also provided. PMID:25312898

    A 2-year-old female Siberian Husky was referred for evaluation of a rectocutaneous fistula of unknown etiology. On evaluation, a rectal tear and an associated perivulvar abscess and draining tract were identified. Several attempts were made to repair the rectocutaneous fistula and associated rectal tear. Primary repair and fascia lata graft repair failed. Successful management was achieved via a laparoscopic-assisted end-on jejunostomy for fecal diversion, and the wound healed readily by second intention. During the period of hospitalization, the dog lost a considerable amount of weight. Particular care should be taken regarding fluid therapy, administration of antimicrobials, and adequate nutrition in patients with rectocutaneous fistulas. Overall, the use of laparoscopic-assisted end-on jejunostomy for fecal diversion in the management of rectocutaneous fistulas in dogs appears to be feasible; end-on or loop jejunostomy may also be an option for the treatment of other diseases of the distal portion of the gastrointestinal tract.

    Objective To examine the incidence and type of obstetric fistula presenting to Hamlin Fistula Ethiopia over a 4-year period. Study design This is a 4-year retrospective survey of obstetric fistula treated at three Hamlin Fistula Hospitals in Ethiopia, where approximately half of all women in the country are treated. The operation logbook was reviewed to identify all new cases of obstetric fistula presenting from 2011 to 2015. New cases of urinary fistula were classified by fistula type (high or low), age, and parity of the woman. Results In total, 2,593 new cases of urinary fistulae were identified in the study period. The number of new cases fell by 20% per year over the 4 years (P<0.001). A total of 1,845 cases (71.1%) were low (ischemic) fistulae, and 804 cases (43.6%) of these had an extreme form of low circumferential fistula. A total of 638 (24.6%) women had a high bladder fistula, which predominantly occurs following surgery, specifically cesarean section or emergency hysterectomy, and 110 (4.2%) women had a ureteric fistula. The incidence of high fistulae increased over the study period from 26.9% to 36.2% (P<0.001). A greater proportion of multiparous women had a high bladder fistula (70.3%) compared with primigravid women (29.7%) (P<0.001). Conversely, a greater proportion of primiparous women experienced a low circumferential fistulae (68.6%) compared with multiparous women (31.4%) (P<0.001). Conclusion There appears to be a decline in the number of Ethiopian women being treated for new obstetric urinary fistulae. However, the type of fistula being presented for treatment is changing, with a rise in high fistulae that very likely occurred following cesarean section and a decline in the classic low fistulae that arise following obstructed childbirth.

    Secondary aortoenteric fistula is a rare and dreaded complication of aortic graft replacement. This case demonstrates successful management of a patient with thoracic aortic graft infection resulting in aortoesophageal fistula and the feasibility of combined endovascular approach as a temporary measure to stabilize the patient in extremis, followed by a definitive surgical repair. The patient had a remote history of descending aortic repair and an emergent thoracic endovascular aortic repair for upper gastrointestinal bleeding 2 months ago. We performed a three-staged operation involving extraanatomic bypass, total infected aortic graft excision, and primary closure of the esophageal perforation with muscle flap coverage, from which he eventually recovered.

    Purpose: To evaluate the value of duplex ultrasound assistance during thromboaspiration of thrombosed arteriovenous fistulae for haemodialysis. Materials and Methods: We prospectively studied 54 thrombosed native fistulae (23 with total thrombosis and 31 with partial thrombosis), in which we performed manual thromboaspiration guided by ultrasonography associated with fluoroscopy. Results: The fistulae were located in the forearm (n = 39) or in the upper arm (n = 15) of 46 patients. Mean patient age was 65 years, and hypertension was the most common risk factor (74 %). Mean access age was 928 days (range 69-2,290), and most fistulae were on the left side (41 cases, 75.92 %). The success rate was 83 % in the total thrombosis group and 100 % in the partial thrombosis group. Including initial failures, the respective primary patency rates in the total thrombosis group and the partial thrombosis group were, respectively, 83 {+-} 8 % (n = 20) and 87 {+-} 6 % (n = 28) at 1 month, 39 {+-} 10 % (n = 10) and 61 {+-} 8 % (n = 20) at 6 months, and 17 {+-} 8 % (n = 5) and 26 {+-} 8 % (n = 9) at 1 year. The mean decrease of fluoroscopy time with ultrasound was 3 min (range 1-5). The mean decrease of radiation dose was 2.6 Gy cm Superscript-Two (range 0.9-4.3]. Conclusion: Ultrasound is a feasible and useful tool in the management of thrombosed native fistulae, thus decreasing radiation exposure, and has no detrimental effect on success rates.

    Esophageus or gaster resection in patients with malignant disease is still a treatment of choice. It is obvious that each surgical procedure in these patients carries some possibility of complications. Esophageo-gastric or esophageo-jejuno anastomosis has a 4-27% frequency of fistula occurrence. All these result in 65% mortality in cases of poorer prognosis. The aim of this paper is not to present all types of complications but to objectively analyse the usefulness of the covered stent placement in the treatment of anastomotic fistulas. We present six patients who were treated for postoperative fistula of esophageo-gastric anastomosis (1 case) or esophageo-jejuno anastomosis (5 cases). All patients were treated with stapler suture for digestive tract reconstruction after malignancy removal during the primary surgical procedure. Signs and symptoms of suture leak between 5-8 days post-surgery were observed. Conservative therapy was not effective. Thus a new method of treatment was employed - covered stent placement. The procedure was performed under X-ray control. In all treated patients there was change for the better and quick reduction of secretion from the fistulas was observed. All patients were discharged from the department after several days and all had survived at 30 days follow-up. Covered esophageal stent placement seems to be a safe and promising method of treatment for patients with anastomotic fistula which significantly reduces mortality and improves quality of live. Our experiences confirms that of other investigators.

    Intra-articular joint capsule injection is a common method used to control postoperative pain as a result of primary total knee arthroplasty (TKA). It is generally considered a safe practice and is highly effective in reducing the need for postoperative opioid administration as well as decreasing recovery time through early mobilization. However, any injection into the posterior knee space has the potential to injure the vascular structures surrounding the knee. Iatrogenic formation of an arteriovenous fistula is a rare complication after TKA, and there are no reported cases of arteriovenous fistula formation as a direct result of intra-articular injection. This case report describes this complication that occurred several days after TKA. The patient had acute pain and swelling in the treated leg. An arteriovenous fistula of the popliteal artery and vein was identified with bilateral Doppler ultrasound and confirmed by angiogram. The most likely inciting event for the formation of the arteriovenous fistula was intra-articular injection of bupivacaine, which likely pierced the popliteal artery and vein, allowing the formation of the patent channel. The patient was treated successfully with stent placement through interventional radiology. Orthopedic surgeons performing intra-articular injections of the knee should refamiliarize themselves with the anatomy and location of the popliteal artery, use smaller-gauge needles, and aspirate the syringe before the injection to decrease the risk of iatrogenic damage to the vasculature or fistula formation.

    Ulnar-basilic fistula (UBF) is an autogenic vascular access option for hemodialysis (HD) first reported in 1967. However, only a few reports dealing with its complications and survival rates have been published in the literature. In the present work the results of 61 UBFs done in 60 adult patients on chronic HD are reported. Forty UBFs were created as primary access and the remaining 21 UBF as secondary access after: (a) thrombosis of an ipsilateral radiocephalic fistula (RCF) in 6 cases, (b) thrombosis of a contralateral RCF in 7 cases, and (c) thrombosis of a brachiocephalic fistula in 2 cases. No episodes of surgical complications, arterial steal, or ulnar nerve damage were observed. Five UBFs thrombosed within the first week after surgery. The 1-, 3-, and 5-year unassisted survival rates were 70.9%, 67.7%, and 57.3%, respectively, which were significantly higher than those reported previously. The inclusion of UBF in routine access plans is recommended.

    Dialysis access procedures and complications are important causes of morbidity and hospitalization for chronic hemodialysis patients. The number of complicated subjects on dialysis is increasing, and creating a successful native arteriovenous fistula for these patients is a challenge. The classic Brescia-Cimino fistula may not be the best first choice for a native vascular access. We describe the surgical technique of middle-arm fistula (MAF) for hemodialysis. A total of 112 surgical procedures were performed on 106 patients with primary unassisted 24- and 48-month patency rates of 93% and 83%, respectively, and a very low incidence of complications. Our approach was found to be a useful method in patients with comorbid factors.

    Pancreas fistula is a well-known and severe complication of pancreaticoduodenectomy. It is difficult to control with conservative therapy, inducing further complications and severe morbidity. Until now, re-operation has been the only way to resolve pancreatic fistula causing complete dehiscence of the pancreatic-enteric anastomosis (complete pancreatic fistula). Percutaneous transgastric fistula drainage is one of the treatments for pancreatic fistula. This procedure allows both pancreas juice drainage and anastomosis re-construction at the same time. This is effective and minimally invasive but difficult to adapt to a long or complicated fistula. In particular, dilatation of the main pancreatic duct is indispensable. This paper reports the successful resolution of a postoperative pancreatic fistula by a two-way-approach percutaneous transgastric fistula drainage procedure. Using a snare catheter from the fistula and a flexible guidewire from the transgastric puncture needle, it can be performed either with or without main pancreatic duct dilatation.

    Acquired fistulas between the tracheobronchial tree and the gastrointestinal tract are rare but serious complications of laparoscopic sleeve gastrectomies with significant morbidity and mortality. With the rising popularity and widespread acceptance of bariatric surgery techniques, the occurrence of gastrobronchial fistulas is being increasingly recognised. We present the case of a 26-year-old woman who underwent laparoscopic sleeve gastrectomy for morbid obesity and presented later with a history of chronic productive cough. Upper gastrointestinal series showed the presence of a communicating fistula between the stomach and the lung, with extravasation of contrast into the lung. The aim of this paper is to highlight the importance of considering the diagnosis of a gastrobronchial fistula in cases of persistent respiratory infections in the postoperative period following bariatric surgery and to review its incidence, clinical manifestations and treatment.

    In three cases of pancreaticocolonic fistula presenting before the stage of exsanguinating hemorrhage of severe sepsis the problem was diagnosed on the basis of the clinical history, visualization of the terminal part of the fistula by roentgenography after a barium enema had been given and, in two cases, demonstration of the communication with the pancreatic ductal system by endoscopic retrograde pancreatography. The lesions were repaired surgically. Pancreaticocolonic fistula should be suspected in a patient with upper abdominal pain who has a history of abdominal pain and excessive alcohol consumption and in whom diarrhea and fever, hematochezia or a disappearing abdominal mass develops. Characteristically barium will collect in the terminal part of the fistula and thus permit a tentative diagnosis; the diagnosis can then be confirmed by endoscopic retrograde pancreatography. With this approach surgical treatment can be carried out earlier and the often fatal course of the disorder can be averted. Images FIG. 1 FIG. 2 FIG. 3 FIG. 4 PMID:709471

    Colocutaneous fistulae secondary to diverticular disease are rare, especially spontaneous fistulae. We report a case of a 74-year-old lady, with no previous history of diverticular disease, presenting with necrotising fasciitis of the anterior abdominal wall in the left iliac fossa, without any other symptoms. Urgent surgery was performed. An initial diagnostic laparoscopy demonstrated a perforated sigmoid diverticulum forming a fistula to the anterior abdominal wall. Following soft tissue debridement, a sigmoid colectomy was performed through a midline laparotomy. Gastrointestinal pathology should be considered as a potential cause of abdominal wall necrotising fasciitis. Our approach of using laparoscopic visualisation to assess for intra-abdominal sources in this context (in the absence of preoperative imaging when imaging could delay treatment) has not been described before. To our knowledge, only two cases of abdominal wall necrotising fasciitis secondary to diverticular disease with a colocutaneous fistula have been reported in the English literature. PMID:27241606

    Arteriovenous (AV) fistulas of cerebral and spinal arteries are characterized angiographically by an immediate AV transition without a capillary bed or "nidus" as occurs in AV malformations (AVM's). The clinical presentation, morphology, radiology, and treatment of 12 patients with cerebral AV fistulas and of 12 patients with spinal AV fistulas are reviewed. In the patients with cerebral lesions, headache and seizure disorders were the most common presentations followed by subarachnoid hemorrhage, cardiac failure, progressive neurological dysfunction, and incidental detection on prenatal ultrasound study. In patients with spinal AV fistulas, weakness and sensory disturbance in the lower extremities were the most frequent clinical presentations followed by back pain, disturbances of micturition, and grand mal seizure. The etiology of the symptom complex produced by AV fistulas in each of these locations differed, with venous hypertension being important in spinal cord lesions. Of the patients with cerebral lesions, nine had a single AV fistula, one had two fistulas, and two had multiple fistulas. An AVM was observed in five patients with fistulas (two large, three small). Nine patients exhibited extramedullary AV fistulas of the spine, of whom eight had a single fistula and one had three fistulas; three patients had intramedullary spinal AV fistulas. An arterial aneurysm was found in association with two fistulas, one cerebral and one spinal. Venous ectasias or varices, frequently exhibiting mural calcification, were observed to be prominent in all AV fistulas involving cerebral arteries and in two involving spinal arteries. The location and size of the venous complexes reflected the diameter of the fistula. In addition to conventional imaging techniques (cerebral angiography, computerized tomography, and magnetic resonance (MR) imaging), MR angiography was a helpful adjunct in the evaluation of fistulas.

    Background Odontogenic cutaneous fistula appears as dimpling or a nodule with purulent discharge, usually in the chin or jaw. Affected patients usually seek help from dermatologists or surgeons rather than from dentists. However, clinical symptoms of facial skin fistula without dental problems can lead to misdiagnosis. Objective The purpose of this study was to investigate the clinical characteristics of patients with odontogenic cutaneous fistulas. Methods This retrospective observational study was performed at Chungbuk National University Hospital by analyzing patients who visited from April 1994 to September 2014. Following clinical and radiographic examinations, the paths and origins of sinus fistulas were determined. Investigated factors were gender, age, morphology, location, originating tooth, time to evolution, recurrence, and treatment method. Results Thirty-three patients (22 males, 11 females; average age 49.2 years) were examined during the investigation period. Thirty-four fistulas were diagnosed as odontogenic cutaneous fistulas. The most common morphology was dimpling (n=14, 41.2%). The various locations observed were related to the originating tooth. The most common site was the mandibular body related to mandibular molars. The referral clinical diagnosis was of odontogenic origin in 6 cases (18.2%). The majority of patients had experienced recurrence after treatment in previous clinics that had failed to diagnose odontogenic cutaneous fistula. Surgical fistulectomy and/or tooth treatment were performed in all cases. All patients were followed-up for 1 year. None showed signs of recurrence. Conclusion Extraoral and dental examinations are required to make a diagnosis of odontogenic cutaneous fistula. Thus, cooperation between dermatologists and dentists is essential. PMID:27489421

    This study evaluates AngioJet thrombectomy of occluded autogenous dialysis fistulae and polytetrafluoroethylene (PTFE) grafts in a UK hemodialysis population. Comparison is made with published data of alternative percutaneous thrombectomy methods. All patients with occluded dialysis fistulae who sought care at the Royal Liverpool University Hospital between October 2006 and June 2008 were included in the study. All patients were treated with the AngioJet Rheolytic Thrombectomy Device (Possis, Minneapolis, MN). Demographics, time of occlusion, adjunctive therapies, complications, and follow-up data have been prospectively recorded. A total of 64 thrombectomy procedures were performed in 48 patients. Forty-four autogenous fistulas were treated in 34 patients (19 brachiocephalic, 8 radiocephalic, and 7 transposed brachiobasilic). Twenty PTFE grafts were treated in 14 patients (9 brachioaxillary, 3 brachiocephalic loop grafts, 1 brachiobasilic, and 1 femoro-femoral). The average length of occlusion was 24 cm. Average time to intervention was 4 days. Immediate primary patency was 91%. Primary patency at 1, 3, and 6 months, respectively, was 71%, 60%, and 37%. Secondary patency at 3, 6, and 12 months was 87%, 77%, and 62%, respectively. Angioplasty was carried out in all procedures. Patients required stent insertion in 34 of the 64 thrombectomies to treat angioplasty-resistant stenoses. Complications included a puncture-site hematoma, and three angioplasty-related vein ruptures in one patient, all treated with covered stent grafts. Two cases of distal brachial arterial embolization were successfully treated by thrombosuction. AngioJet thrombectomy in dialysis access occlusion is safe and effective, comparing favorably with other methods.

    AIM: To prospectively perform the PERFACT procedure in supralevator anal fistula/abscess. METHODS: Magnetic resonance imaging was done preoperatively in all the patients. Proximal cauterization around the internal opening, emptying regularly of fistula tracts and curettage of tracts (PERFACT) was done in all patients with supralevator fistula or abscess. All types of anal fistula and/or abscess with supralevator extension, whether intersphincteric or transsphincteric, were included in the study. The internal opening along with the adjacent mucosa was electrocauterized. The resulting wound was left open to heal by secondary intention so as to heal (close) the internal opening by granulation tissue. The supralevator tract/abscess was drained and thoroughly curetted. It was regularly cleaned and kept empty in the postoperative period. The primary outcome parameter was complete fistula healing. The secondary outcome parameters were return to work and change in incontinence scores (Vaizey objective scoring system) assessed preoperatively and at 3 mo after surgery. RESULTS: Seventeen patients were prospectively enrolled and followed for a median of 13 mo (range 5-21 mo). Mean age was 41.1 ± 13.4 years, M:F - 15:2. Fourteen (82.4%) had a recurrent fistula, 8 (47.1%) had an associated abscess, 14 (82.4%) had multiple tracts and 5 (29.4%) had horseshoe fistulae. Infralevator part of fistula was intersphincteric in 4 and transsphincteric in 13 patients. Two patients were excluded. Eleven out of fifteen (73.3%) were cured and 26.7% (4/15) had a recurrence. Two patients with recurrence were reoperated on with the same procedure and one was cured. Thus, the overall healing rate was 80% (12/15). All the patients could resume normal work within 48 h of surgery. There was no deterioration in incontinence scores (Vaizey objective scoring system). This is the largest series of supralevator fistula-in-ano (SLF) published to date. CONCLUSION: PERFACT procedure is an effective single

Patients were treated using 4 operative approaches: fistulotomy, fistulectomy, seton placement and rectal advancement flap. Data analyzed included: age, gender, type of fistula, operative intervention, healing rate, postoperative complications, reinterventions and recurrence. Results Etiologies of fistulas were cryptoglandular (n = 218), Crohn's disease (n = 26) and Ulcerative Colitis (n = 3). Fistulae were classified as simple -intersphincteric 57 (23%), low transphincteric 28 (11%) and complex -high transphicteric 122 (49%), suprasphincteric 2 (0.8%), extrasphinteric 2 (0.8%), recto-vaginal 7 (2.8%) Crohn 26 (10%) and UC 3 (1.2%). The most common surgical procedure was the placement of seton (62%), usually applied in case of complex fistulae and Crohn's patients. Eighty-five patients (34%) underwent fistulotomy, mainly for intersphincteric and mid/low transphincteric tracts. Crohn's patients were submitted to placement of one or more loose setons. The main treatment successfully eradicated the primary fistula tract in 151/247 patients (61%). Three cases of major incontinence (1.3%) were detected during the follow-up period; Furthermore, three patients complained minor incontinence that was successfully treated by biofeedback and permacol injection into the internal anal sphincter. Conclusions This prospective audit demonstrates an high proportion of complex anal fistulae treated by seton

    Background Bronchopleural fistula (BPF) is an infrequent but life-threatening complication after lung surgery. Tentative closure of the fistula and irrigation have been the conventional treatments, but are also surgically challenging and associated with a considerable failure rate. This study reports on a conservative practice of this difficult issue, in aim to examine its outcomes. Method All enrolled cases were handled consecutively from September 2006 to June 2015. The empyema was first properly drained till disseminated pneumonia controlled. After conducting lavage, tube drainage was gradually transited to postural drainage. During the follow-up, information on tube removal, fistula healing, and survival were recorded. Results Thirteen cases were enrolled, including 9 rights and 4 lefts. The primary diseases were lung cancer [10], lung abscess [1], organizing pneumonia [1], and aspergillosis [1]. Early fistula (≤30 days postoperatively) occurred in 8 cases and late fistula (>30 days postoperatively) in 5 cases. Two patients underwent debridement to ascertain complete drainage. Chest tubes retained from 7 to 114 days (mean 40.54±30.49 days) before removal. At follow-up, we observed gradually narrowing-down of all residual cavities, and symptoms of fistula and empyema eventually disappeared in all patients. No complication or death occurred during the follow-up. Conclusions Conservative management by a combination of tube and postural drainage provides an effective and safe treatment for empyema-complicated post-lobectomy BPFs. PMID:27499946

    Objectives: The aim of this study was to evaluate in a multicenter randomized controlled trial (RCT) whether pancreaticojejunostomy (PJ) of pancreatic stump decreases the incidence of pancreatic fistula after distal pancreatectomy (DP) compared with stapler closure. Background: Several studies reported that PJ of pancreatic stump reduces the incidence of pancreatic fistula after DP. However, no RCT has confirmed the efficacy of PJ of pancreatic stump. Methods: One hundred thirty-six patients scheduled for DP were enrolled in this study between June 2011 and March 2014 at 6 high-volume surgical centers in Japan. Enrolled patients were randomized to either stapler closure or PJ. The primary endpoint was the incidence of pancreatic fistula based on the International Study Group on Pancreatic Fistula criteria. This RCT was registered with ClinicalTrials.gov (NCT01384617). Results: Sixty-one patients randomized to stapler and 62 patients randomized to PJ were analyzed by intention-to-treat. Pancreatic fistula occurred in 23 patients (37.7%) in the stapler closure group and 24 (38.7%) in the PJ group (P = 0.332) in intention-to-treat analysis. The incidence of clinically relevant pancreatic fistula (grade B or C) was 16.4% for stapler closure and 9.7% for PJ (P = 0.201). Mortality was zero in both groups. In a subgroup analysis for thickness of pancreas greater than 12 mm, the incidence of clinically relevant pancreatic fistula occurred in 22.2% of the patients in the stapler closure group and in 6.2% of the PJ group (P = 0.080). Conclusions: PJ of the pancreatic stump during DP does not reduce pancreatic fistula compared with stapler closure. PMID:26473652

    Stone formation within the intestinal lumen is called enterolith. This stone can encroach into the lumen causing obstruction and surgical emergency. Jejunal obstruction by an enterolith is a very rare entity and often missed preoperatively. To our knowledge, most cases of jejunal obstruction, secondary to stone, were associated with biliary disease (cholecystoenteric fistula), bezoar, jejunal diverticulosis, or foreign body. Hereby we present a rare case report of small bowel obstruction in an elderly man who was diagnosed lately to have primary proximal jejunal obstruction by an enterolith without evidence of a cholecystoenteric fistula or jejunal diverticulosis. This patient underwent laparotomy, enterotomy with stone extraction, and subsequent primary repair of the bowel. PMID:27803836

    PurposeThis study aimed to retrospectively assess the efficacy of a bare intervascular tunnel for salvage of a thrombosed hemodialysis fistula. We examined the clinical outcomes and provided follow-up images of the bare intervascular tunnel.Materials and MethodsEight thrombosed fistulas lacked available recanalizable outflow veins were included in this study. These fistulas were salvaged by re-directing access site flow to a new outflow vein through a percutaneously created intervascular tunnel without stent graft placement. The post-intervention primary and secondary access patency rates were calculated using the Kaplan–Meier method.ResultsThe procedural and clinical success rates were 100 %. Post-intervention primary and secondary access patency at 300 days were 18.7 ± 15.8 and 87.5 ± 11.7 %, respectively. The mean follow-up period was 218.7 days (range 10–368 days). One patient died of acute myocardial infarction 10 days after the procedure. No other major complications were observed. Minor complications, such as swelling, ecchymosis, and pain around the tunnel, occurred in all of the patients.ConclusionsPercutaneous creation of a bare intervascular tunnel is a treatment option for thrombosed hemodialysis fistulas without recanalizable outflow in selected patients.

    Introduction Subjects who undergo haemodialysis are living longer, which necessitates increasingly complex procedures for formation of arteriovenous fistulas. Basilic veins provide valuable additional venous 'real estate' but surgical transposition of vessels is required, which required a cosmetically disfiguring incision. A minimally invasive transposition method provides an excellent aesthetic alternative without compromised outcomes. Methods A retrospective review was made of minimally invasive brachiobasilic fistula transpositions (using two short incisions of <4 cm) between February 2005 and July 2011. Primary endpoints were one-year patency as well as the perioperative and late complications of the procedure. Results Thirty-one patients underwent 32 transposition procedures (eight pre-dialysis cases; 24 haemodialysis patients). All patients were treated with a minimally invasive method. Thirty-one procedures resulted in primary patency, with the single failure refashioned successfully. The only indication for a more invasive approach was intraoperative complications (two haematomas). All other complications presented late and were amenable to intervention (one aneurysm, one peri-anastomotic stricture). Conclusion Formation of arteriovenous fistulae using minimally invasive methods is a novel approach that ensures fistula patency with improved aesthetic outcomes and without significant morbidity.

    Five cases of aorto-enteric fistula (AEF) are reported. The first case was a primary AEF from rupture of the infrarenal section of the abdominal aorta treated successfully by an obliteration and graft. The second patient had a primary AEF from rupture of an abdominal aorta aneurysm, complicated after an obliteration and graft of the primary AEF, requiring excision of the graft and an extra-anatomical shunt (EAS): healing following parenteral hypernutrition. The third case, a patient with a primary AEF from rupture of an aortic adventitial cyst in the left colon, died from septic complications. The fourth case died with heart rhythm disorders on the 4th day after resection and EAS for an aortic fistula. The fifth patient had a secondary AEF with cataclysmic digestive hemorrhage: excision of the graft with digestive closure and aortofemoral bypass did not prevent a fatal outcome on the 20 th day. Digestive hemorrhage and septic signs may be combined or occur as isolated complications. The most valid complementary investigation is fibroscopy, bacteriological culture of arterial blood distal to the prosthesis having an orientation value. Ultrasound, computed tomography or Gallium scintigraphy imaging may detect a retroperitoneal abscess. Effective treatment of all aneurysms can prevent primary AEF and avoidance of infection and interpositioning of viable tissue between duodenum and anastomotic line reduce the risk of secondary AEF. Maximum chances of success require aggressive surgery: aortic ligature; excision of all septic material and duodenal closure or segmental digestive resection with discharge of proximal pocket. Lower limb ischemia is treated by insertion of an EAS.

    Aims: The purpose of the study was to evaluate the role of Magnetic Resonance Imaging in detection and characterization of perianal fistulae and correlating it with surgical findings. Methods: Fifty consecutive patients with suspected perianal fistulae having one or more external openings were prospectively selected for MRI evaluation. Previously operated or patients with recurrent perianal disease were excluded from the study. MRI findings were recorded according to “St. James’s University Hospital MR Imaging Classification of Perianal Fistulae” and correlated with surgical observations. Finally, comparison between T2-weighted fat saturated and postcontrast T1-weighted fat saturated sequences was done. Results: Amongst the total of 50 patients, per-operative findings confirmed perianal fistulae in 45 patients. The sensitivity and specificity of MRI in correctly detecting and grading the primary tract was found to be 95.56% and 80% respectively; for abscess, it was 87.50% and 95.24% respectively. High sensitivity was also discerned in identification of secondary tract (93.75%), correct localization of internal opening (95.83%) and for correctly detecting the horse-shoeing (87.50%). Our assumption of null hypothesis was accepted on comparing results of T2-weighted fat saturated sequences and postcontrast T1-weighted fat saturated sequences. Conclusion: Magnetic Resonance Imaging (MRI) was highly accurate in assessment of surgically important parameters (primary tract and its grading, internal opening, secondary tract, abscess, horseshoeing) of perianal fistulae. Comparison of results of imaging findings on T2-weighted and postcontrast T1-weighted fat saturated sequences were statistically similar, so contrast study can be omitted, particularly while evaluating primary / previously unoperated perianal fistulae.

    Pharyngocutaneous fistulae are rare complications of anterior spine surgery occurring in less than 0.1% of all anterior surgery cases. We report a case of a 19 year old female who sustained a C6 burst fracture with complete quadriplegia. She was treated urgently with a C6 corpectomy with anterior cage and plating followed by posterior cervical stabilization at another institution. Post operatively she developed a pharyngocutaneous fistula that failed to heal despite several attempts of closure and esophageal exclusion with a Jpeg tube. The patient was eventually successfully treated with a three-stage procedure consisting of firstly a posterior approach to reinforce the posterior stabilization of the cervical spine that was felt to be inadequate, secondly an anterior approach with removal of all the anterior instrumentation followed by iliac crest bone graft and thirdly a superior based sternocleidomastoid flap that was interposed between the esophagus and the anterior cervical spine. The patient's fistula healed successfully. However, yet asymptomatic, the anterior iliac crest bone graft resorbed almost completely at 16 months follow up. In light of this complication, we discuss the surgical options for the treatment of pharyngocutaneous fistulae and the closure of this fistula using a superiorly based sternocleidomastoid muscle flap.

    Gastrointestinal leaks and fistulae can be serious acute complications or chronic morbid conditions resulting from inflammatory, malignant, or postsurgical states. Endoscopic closure of gastrointestinal leaks and fistulae represents major progress in the treatment of patients with these complex presentations. The main goal of endoscopic therapy is the interruption of the flow of luminal contents across a gastrointestinal defect. In consideration of the proper endoscopic approach to luminal closure, several basic principles must be considered. Undrained cavities and fluid collections must often first be drained percutaneously, and the percutaneous drain provides an important measure of safety for subsequent endoscopic luminal manipulations. The size and exact location of the leak/fistula, as well as the viability of the surrounding tissue, must be defined. Almost all complex leaks and fistulae must be approached in a multidisciplinary manner, collaborating with colleagues in nutrition, radiology, and surgery. Currently, gastrointestinal leaks and fistulae may be managed endoscopically by using 1 or more of the following modalities: stent placement, clip closure (including through-the-scope clips and over-the-scope devices), endoscopic suturing, and the injection of tissue sealants. In this article, we discuss these modalities and review the published outcomes data regarding each approach as well as practical considerations for successful closure of luminal defects.

    Background Low transsphincteric fistulas less than 1/3 of the sphincter complex are easy to treat by fistulotomy with a high success rate. High transsphincteric fistulas remain a surgical challenge. Various surgical procedures are available, but recurrence rates of these techniques are disappointingly high. The mucosal flap advancement is considered the gold standard for the treatment of high perianal fistula of cryptoglandular origin by most colorectal surgeons. In the literature a recurrence rate between 0 and 63% is reported for the mucosal flap advancement. Recently Armstrong and colleagues reported on a new biologic anal fistula plug, a bioabsorbable xenograft made of lyophilized porcine intestinal submucosa. Their prospective series of 15 patients with high perianal fistula treated with the anal fistula plug showed promising results. The anal fistula plug trial is designed to compare the anal fistula plug with the mucosal flap advancement in the treatment of high perianal fistula in terms of success rate, continence, postoperative pain, and quality of life. Methods/design The PLUG trial is a randomized controlled multicenter trial. Sixty patients with high perianal fistulas of cryptoglandular origin will be randomized to either the fistula plug or the mucosal advancement flap. Study parameters will be anorectal fistula closure-rate, continence, post-operative pain, and quality of life. Patients will be followed-up at two weeks, four weeks, and 16 weeks. At the final follow-up closure rate is determined by clinical examination by a surgeon blinded for the intervention. Discussion Before broadly implementing the anal fistula plug results of randomized trials using the plug should be awaited. This randomized controlled trial comparing the anal fistula plug and the mucosal advancement flap should provide evidence regarding the effectiveness of the anal fistula plug in the treatment of high perianal fistulas.

    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. PMID:27066439

    Six cases of full spontaneous closure of congenital coronary artery fistulas, and one case of near closure, as seen by colour Doppler echocardiography, are presented. It is worth reconsidering the classical view that nearly all cases of spontaneous closure are eligible for surgical or percutaneous correction to prevent the development of significant and potentially fatal complications. As the natural course of coronary artery fistulas is still poorly defined, asymptomatic patients, especially those under 7 years old with small shunts, should be periodically followed up by echocardiography rather than be subjected to operative closure, even by catheterisation.

    Six patients with congenital coronary artery fistula underwent successful corrective surgery. Precise diagnosis was established either by retrograde aortography or more recently by selective arteriography. The left coronary artery was involved in four and the right in two cases. The fistula communicated with the right ventricle in three and the right atrium in three subjects. The operative approach is dictated by the site of entry of the vessel into the cardiac chamber. The use of cardiopulmonary bypass for intracardiac repair allows accurate closure of the fistula thereby reducing the chances of recurrence. A follow-up of one to seven years showed that all patients are asymptomatic and leading normal lives. Images PMID:7314003

    Surgery is considered to be the treatment of choice for vascular injuries caused by trauma. However, endovascular techniques are emerging as an alternative means of treatment. In this article, we describe three patients with posttraumatic arteriovenous fistulae in different body regions that were managed using endovascular techniques. Each case had its unique set of associated problems requiring innovative methods and a multidisciplinary approach. While the short-term results are encouraging, long-term follow-up of posttraumatic arteriovenous fistulae that have been treated with endovascular techniques is still required.

    A fistula is an abnormal opening between two or more organs or structures. Wound drainage containment is a key component of nonsurgical fistula management and may include pouches, skin barriers, transparent dressings, troughing procedures, saddle bagging, bridging, and condom and suction catheters used in combination with complex or routine pouching. Following extensive abdominal surgery, the wound of a 50-year-old woman dehisced and a colocutaneous fistula formed inside the wound. The wound containing the fistula, which was draining liquid stool, was too large for existing commercial pouching systems. When initial management efforts, including negative pressure wound therapy, failed to achieve containment goals, clinicians adapted the negative pressure wound therapy dressing to surround the fistula, which helped facilitate therapy while providing a platform for an ostomy appliance to contain the fistula drainage. The system was changed every 2 days until discharge. The wound and fistula management combination improved patient comfort and mobility, facilitated healing, and reduced patient dietary restrictions.

    Surgical management of labyrinthine fistulas caused by cholesteatoma remains controversial. In 213 patients with middle ear surgery for cholesteatoma, 18 patients (18 ears-8.5%) presented a labyrinthine fistula. These cases are reviewed in the present paper. Symptoms, audiometry, pre-operative imaging, surgical procedure and results are discussed. In all cases total removal of the pathology was pursued with preservation of cochlear function. A two-stage closed technique was used. During the first stage reconstruction with tympano-ossicular allografts, according to the technique of J. Marquet, was performed. A second look followed one year later. Three ears were deaf pre-operatively. Improvement of bone conduction was observed in more than 50% and hearing preservation in all other cases but one. In one ear total deafness occurred from extensive intralabyrinthine invasion by cholesteatoma, demanding a labyrinthectomy. The hearing was preserved in four cases in which an amputation of a large part of the membranous labyrinth could be observed. Since neither pre-operative clinical examination nor imaging can be relied on to reveal a fistula, the surgeon needs to be prepared for unexpected fistulas. PMID:8213141

    Congenital fistulas are the most common of the coronary arterial malformations and with the widespread use of selective coronary arteriography are being recognized with increasing frequency. Twenty-eight patients with congenital coronary fistulas have been evaluated at the Duke University Medical Center between 1960 and 1981. An additional 258 patients have previously been reported in the literature, making a total of 286 available for review. The right coronary artery is most commonly involved, and the fistulous communication is most often to the right ventricle, right atrium or pulmonary artery. Slightly more than half of the patients with coronary fistulas are symptomatic at the time the diagnosis is made. Surgical correction is strongly recommended to prevent the development of congestive heart failure, angina, subacute bacterial endocarditis, myocardial infarction, and pulmonary hypertension, as well as coronary aneurysm formation, with subsequent rupture or embolization. There were no operative or late deaths in the patients who underwent operations. Moreover, there have been no recurrent fistulas during a mean follow-up period of ten years. The risks of operative correction appear to be considerably less than the potential for development of serious and potentially fatal complications, even in asymptomatic patients. Images Fig. 2a.

    This article describes a 22-year-old man who presented to the Howard University Hospital emergency room with acute onset of swelling, proptosis, and decreased vision in the right eye preceded by 24 hours of nausea and vomiting. The patient's visual acuity was count fingers in the involved eye with marked proptosis and limitation of ocular motility. There was no history given of any ocular or head trauma. A computed tomography scan of the orbits showed diffuse symmetric enlargement of the extraocular muscles of the right eye, felt to be consistent with an orbital inflammatory pseudotumor. The patient was treated with intravenous steroids initially, then placed on oral prednisone. After minimal improvement on the steroids, a selective external carotid angiogram showed a moderate-sized dural cavernous sinus fistula. The patient underwent selective embolization of the fistula with rapid resolution of periorbital edema and proptosis. Visual acuity was stabilized at 20/200 in the right eye. The differential diagnosis and pathogenesis of carotid cavernous sinus fistulas and the likely pathogenesis of the fistula in this case are discussed. Images Figure 1 Figure 2 Figure 3 PMID:8046763

    Biliary fistula is an occasional complication of cholecystectomy and are usually associated to retained biliary stones, surgical trauma of the biliary ducts and local infection. They were mainly treated by surgical methods up to the acquisition of the new endoscopic and percutaneous techniques used together with parenteral and enteral nutrition and new antibiotics. A total of seven patients with diagnosis of biliary fistula were seen between 1984 and 1990 at the "Unidad de Gastroenterología y Cirugía Digestiva" of the Clínica Sanatrix en Caracas. Average age was 50 with ranged between 31 and 76, 4 were male and 3 female. The fistulas were in 1 due to necrotizing pancreatitis, in 3 to lost of the ligation of the cystic duct, 2 were due to accidental injury of the common duct and the last case was a partial dehiscence of a choledoco-jejunostomy after the resection of a common duct cyst. Four of the cases were choledoco-cutaneous fistula, one hepatocutaneous, two hepatoduodenal. All the seven patients had subhepatic collections, one had a retroperitoneal collection, two had subdiaphragmatic collections and one had multiple hepatic abscesses. The abdominal collections were treated by percutaneous drainage using mainly the Ring-McLean and Van Sonnenberg tubes. The fistula was occluded with biliary prosthesis in four cases, using either endoscopic, percutaneous or mixed technique to place the stent. Patency of the stents ranged between 2 weeks and 24 months. Control time was from 2 to 40 months.(ABSTRACT TRUNCATED AT 250 WORDS)

Case 1 was a 70-year-old man who underwent resection of the right lower pulmonary lobe due to right lung metastasis of sigmoid colon cancer. A bronchopleural fistula was found on day 28 after surgery. Infection was controlled by antibiotic administration and tube drainage. Closure of the bronchopleural stump, thoracoplasty and plombage of latissimus dorsi muscles were performed for single-stage closure without open treatment, based on a negative pleural effusion culture. Case 2 was a 64-year-old man who underwent right lower pulmonary lobe resection due to right lung cancer. A bronchopleural fistula was found on day 14 after surgery. In single-stage closure, thoracoplasty and plombage of latissimus dorsi muscles were performed due to infection control and a negative pleural effusion culture. Both cases had a good postoperative course. PMID:26004108

    Introduction Non-maturation and post-maturation venous stenosis are the primary causes of failure within arteriovenous fistulae (AVFs). Although the exact mechanisms triggering failure remain unclear, abnormal hemodynamic profiles are thought to mediate vascular remodelling and can adversely impact on fistula patency. Aim The review aims to clarify the role of shear stress on outward remodelling during maturation and evaluate the evidence supporting theories related to the localisation and development of intimal hyperplasia within AVFs. Methods A systematic review of studies comparing remodelling data with hemodynamic data obtained from computational fluid dynamics of AVFs during and after maturation was conducted. Results Outward remodelling occurred to reduce or normalise the level of shear stress over time in fistulae with a large radius of curvature (curved) whereas shear stress was found to augment over time in fistulae with a small radius of curvature (straight) coinciding with minimal to no increases in lumen area. Although this review highlighted that there is a growing body of evidence suggesting low and oscillating shear stress may stimulate the initiation and development of intimal medial thickening within AVFs. Further lines of evidence are needed to support the disturbed flow theory and outward remodelling findings before surgical configurations and treatment strategies are optimised to conform to them. This review highlighted that variation between the time of analysis, classification of IH, resolution of simulations, data processing techniques and omission of various shear stress metrics prevented forming pooling of data amongst studies. Conclusion Standardised measurements and data processing techniques are needed to comprehensively evaluate the relationship between shear stress and intimal medial thickening.

    PurposeThe study was designed to assess outcomes of arteriovenous (AV) accesses after interventional stent-graft deployment in haemodialysis patients.Materials and Methods63 haemodialysis patients with 66 AV fistulas and AV grafts were treated by interventional stent-graft deployment from 2006 to 2012 at our hospital. Data of these patients were retrospectively analysed for location of deployed stent-grafts, occurrence and location of (re-)stenosis and (re-)thrombosis. Complex stenosis was the most frequent indication for stent-graft deployment (45.5 %), followed by complications of angioplasty with vessel rupture or dissection (31.8 %).ResultsA high rate of procedural success was achieved (98.5 %). The most frequent location of the deployed stent-graft was the draining vein (66.7 %). Stent-graft deployment was more frequent in AV grafts than in AV fistulas. Primary patency was 45.5 % at 6 month, 31.3 % at 12 month and 19.2 % at 24 month. Primary patency was significantly better for AV fistulas than for AV grafts with deployed stent-grafts. Patency of the deployed stent-graft was much better than overall AV access primary patency with deployed stent-graft. Re-stenosis with thrombosis was the most frequent indication for re-intervention. Most frequent location of re-stenosis was the draining vein (37.1 %), followed by stenosis at the AV access (29.5 %) and the deployed stent-graft (23.5 %).ConclusionRe-stenosis and re-thrombosis remain frequent in AV fistulas and AV grafts in haemodialysis patients despite stent-graft deployment. Re-stenosis of the deployed stent-graft is, only in the minority of the cases, responsible for AV access dysfunction.

    A lower urinary tract fistula consist in an abnormal connection between bladder, urethra and adjacent abdominal organs or skin. There are several types of urinary fistulas in paediatric age and they may be congenital or acquired. Etiology may be due to embriological defects, infectious processes, malignant tumours, pelvic irradiation as well as complications following surgical procedures, especially postsurgical repair of hypospadia or epispadia. Clinical presentation depends on the type of fistula and diagnosis is based on signs, symptoms and radiological or endoscopic examinations. We performed PubMed research using terms such as lower urinary fistulae, urology and paediatrics and we consulted medical texts. We reviewed selected articles and used the relevant ones to perform our study concentrating on classification, diagnosis and treatment of different types of fistulas. Paediatric lower urinary fistulas are an uncommon pathology, but the knowledge of their etiology and classification is important to recognise them and lead the physician to an appropriate treatment, which is surgical in most cases.

    Superior mesenteric arteriovenous fistulas are rare, especially when iatrogenic in origin. Management of these fistulas can be surgical or endovascular. Endovascular embolisation is the preferred modality with a low rate of complications. Among the reported complications, bowel ischaemia is considered an unlikely occurrence. We report a case of a complex iatrogenic arterioportal fistula that was managed by endovascular embolisation and controlled through both its inflow and outflow, and was later complicated by bowel ischaemia.

    Chyle leak following axillary lymph node clearance is a rare yet important complication. The treatment of postoperative chyle fistula still remains unclear. Conservative management is the first line of treatment. It includes axillary drains on continuous suction, pressure dressings, bed rest, and nutritional modifications. The use of somatostatin analogue is well documented as a treatment for chylous fistulas after neck surgery. We present a case of chylous fistula after axillary surgery resolved with the use of octreotide. PMID:26925285

    Nineteen consecutive cases of simple fistula-in-ano treated with fistulotomy and marsupialisation were retrospectively reviewed. Fourteen cases were simple intersphincteric and the remaining 5 cases were uncomplicated transphincteric fistulae. The cases were followed up for between 3 to 10 months (mean 6.9 months). There were no reports of bowel incontinence or recurrence of fistula. The advantages of this 'tissue conserving' procedure are discussed in the paper. PMID:1631585

    Objective: To investigate the clinical efficacy of laparoscopic repair of iatrogenic vesicovaginal fistulas (VVF) and rectovaginal fistulas. Methods: Seventeen female patients with iatrogenic fistulas (11 cases of VVF and 6 cases of high rectovaginal fistulas) were included. All patients were hospitalized and underwent laparoscopic fistula repair in our hospital between 2008 and 2012. The mean age of the patients was 44.8 ± 9.1 years. The fistulas and scar tissue were completely excised by laparoscopy, orifices were tension-free closed using absorbable sutures, omental flaps were interposed between the vagina and the bladder or rectum, and drainage was kept after repair. Results: Laparoscopic repair of fistulas was successful in all 17 patients. No complication was found during or after repair. No reoperation was needed after the repair. The operative time was 80.2 ± 30.0 minutes (range 50-140 minutes). The blood loss was 229.4 ± 101.6 ml (range 100-400 ml). The double J catheters were placed in 7 patients and removed 1-2 months after repair. Eight VVF patients underwent cystoscopy 3 months after laparoscopic repair and there were no abnormal findings. The follow-up time was 17.1 ± 6.5 months (range 8-29 months). Conclusion: Laparoscopic repair of VVF and rectovaginal fistulas is a safe and an effective minimally invasive procedure for treatment of iatrogenic fistula. PMID:25932174

    2016-09-01

    Pelvic fistulae are an abnormal communication among the genitourinary tract, the gastrointestinal tract, and the vagina or perineum. Genital tract fistulae have been described in the medical literature for the past several thousand years. Advancements in both the diagnosis and treatment of vaginal fistulae have been obtained over the past century as surgical interventions have become safer and surgical techniques have improved. The most common cause of fistulae worldwide is obstructed labor. In developed countries, fistulae most commonly occur after benign gynecologic surgery, but obstructed labor, malignancy, radiation exposure, and inflammatory bowel disease can also cause fistulae. Fistulae significantly affect quality of life. Diagnostic studies and radiologic imaging can help aid the diagnosis, but a thorough physical examination is the most important component in the evaluation and diagnosis of a fistula. Temporizing treatments are available to help ease patient suffering until surgical management can be performed. Surgical repairs can be performed using an abdominal, vaginal, or transanal approach. Although technically challenging, surgical repair is usually successful, but closure of the fistula tract does not guarantee continence of urine or feces, because there is often underlying damage to the bowel and bladder.

    Summary Magnetic resonance imaging (MRI) depicts infectious foci in the perianal region better than any other imaging modality. MRI allows definition of the fistula, associated abscess formation and its secondary extensions. Accurate information is necessary for surgical treatment and to obtain a decrease in the incidence of recurrence and complications. Radiologists should be familiar with anatomical and pathological findings of perianal fistulas and classify them using the MRI – based grading system. The purpose of this article was to provide an overview for evaluation of perianal fistulas, examples of various fistula types and their classification. PMID:25550766

    Summary Carotid-cavernous fistulas are abnormal communications between the carotid system and the cavernous sinus. Elevated venous pressure produces congestion in the orbit with resultant transudation of fluid and increased intraocular pressure, thereby leading to secondary glaucoma which may result in visual loss. Immediate treatment is hence, warranted in these cases. The planning of endovascular management is dependent on many parameters, the most important of which are the size and location of the fistula. Since these are high-flow fistulas, assessment requires certain manoeuvers. Heuber manoeuver is one of the manoeuvers used to demonstrate the size of the fistula. PMID:27781074

    A fistula of the lesser sphenoid wing sinus is a rare dural arteriovenous fistula resulting from a connection between the middle meningeal artery and recipient vein in the sinus of the lesser sphenoid wing. In this report, MRI/magnetic resonance angiography of a 54-year-old man who presented with sudden-onset glaucoma and proptosis revealed a fistula in this anatomic location. Drainage patterns here may account for the absence of serious complications and optimistic prognosis following embolization. Care in diagnosis is required to avoid superfluous procedures, because classic signs of the more common carotid-cavernous fistula are absent. PMID:19966661

    In the present report, the first reported case of cytomegalovirus (CMV)-associated enterocolic fistula in an HIV/AIDS patient is described. CMV colitis is the second most common presentation of CMV infection in immunocompromised patients. CMV-associated enteric fistulae are an exceedingly rare complication, with only four previous cases described: a gastrocolic, an enterocutaneous, a rectovaginal and a colocutaneous fistula. Management of these patient demonstrates the importance of treating the precipitating viral infection before considering surgical intervention of the enterocolic fistula.

    We report an unusual case of a pancreatic fistula communicating with an appendicectomy wound. This occurred following an episode of acute haemorrhagic pancreatitis. The patient was initially admitted with signs and symptoms indicating appendicitis and went to theatre for an open appendicectomy. However, this did not resolve his symptoms and a laparotomy was performed the next day revealing haemorrhagic pancreatitis. He endured a stormy post-operative course, the cause of which was found to be an external pancreatic fistula with discharge of amylase-rich fluid from the Lanz incision. A trial of conservative management failed despite multiple percutaneous drainage procedures and treatment with broad-spectrum antibiotics. After a second opinion was sought, it was decided to fit a roux loop anastomosis between the head of the pancreas and the duodenum to divert the fistulous fluid. This procedure was a success and the patient remains well 2 years later.

    Pharyngocutaneous fistula (PCF) is the most common complication following total laryngectomy and the most difficult to manage. It often causes increased morbidity, delays starting adjuvant therapy, prolongs hospitalisation, increases treatment costs and reduces the quality of life (QoL). The objective of this study is to analyse the predisposing factors and the most important nutritional parameters related to the development of PCF in patients undergoing total laryngectomy and to suggest medical alternatives that might improve results. We performed a retrospective study of 69 patients who underwent either primary or salvage total laryngectomy in our department between January 2008 and January 2012. Risk factors for fistula formation were analysed including tumour characteristics (histology, grading, AJCC stage), treatment (primary or salvage surgery, extent of resection, flap reconstruction, preoperative radiotherapy), comorbidity and nutritional status (preoperative haemoglobin, albumin and prealbumin levels and their changes during hospitalisation). Twenty-four patients developed a PCF (overall incidence 34.8%). Fistula formation was significantly higher in patients with diabetes, preoperative malnutrition (identified from low preoperative albumin and prealbumin levels). After specific nutritional evaluation and support, no patient developed a PCF. Risk factors for PCF formation are extensively treated in the literature but identification of high-risk patients is still controversial. Our study demonstrates that nutritional status of the patient, assessed by preoperative albumin, is also an important risk factor for PCF formation in addition to classical factors. Maintenance of a normal perioperative nutritional status can be helpful to avoid this complication. PMID:26824210

    Invasive pulmonary aspergillosis (IPA) is commonly seen in immunocompromised patients, and tracheoesophageal fistula (TEF) induced by IPA is rare and seldom reported. Management of these critically ill patients is challenging and often requires a multidisciplinary approach. The authors reported an adult suffering from aplastic anemia who developed TEF caused by IPA. The diagnosis was confirmed following bronchoscopy and histopathological examination. Antifungal and bronchoscopic intervention provided a cure without any recurrence as yet.

    With the development of endoscopic techniques, the treatment of tracheoesophageal fistula (TEF) has made marked progress. As surgical intervention is often not an advisable option due to advanced malignancy and poor performance status of the patients, bronchoscopic intervention provides a good choice to palliate symptoms and reconstruct the airway and esophagus. In this review, we focus on the application of interventional therapy of TEF, especially the application of airway stenting, and highlight some representative cases referred to our department for treatment.

    The primary pancreatic hydatid (echinococcal) cyst is extremely rare with a reported incidence of <1%. Owing to its rareness and a considerable overlap of imaging features, a preoperative diagnosis is usually difficult. The dilemma in confirming this benign diagnosis has often questioned the extent of radical pancreatic resection. The involvement of pancreatic duct (cystopancreatic duct fistula) further complicates the management of such cystic lesions. In this report, we present a case of isolated hydatid cyst of the pancreatic body and tail communicating with the pancreatic duct. Cystogastrostomy preceded by partial cystectomy in the same setting has never been reported to date. The patient had an uneventful postoperative course and follow-up showed no evidence of cyst recurrence or dissemination. We consider this a safe surgical option in longstanding large cysts, especially if a cystopancreatic fistula is detected beforehand. The success of such a procedure however may rely on the size and thickness of the cyst wall to support this anastomosis. PMID:27512554

    Obstetric experience, clinical and socio-economic characteristics, and reasons for preference of place of delivery of 639 fistula patients admitted to the Addis Ababa Fistula Hospital between May 1999 and February 2000 are described About 94% of fistula patients were married and 83.6% had been through with the delivery caused the fistula before the age of 20. The mean ages at the first marriage and at the causative delivery were 14.7 (sd=2.6) and 17.8 (sd=3.2) years respectively. Mean height of fistula patients studied was 149 cms (sd=8). About 64% were primiparous, 44% (279) delivered at home, and labor lasted for 3.8 days on average. Majority of fistula patients mentioned distance as a main problem for the delays. Lack of money, poor knowledge and delay in referral were the other frequently mentioned reasons for the delays. About 62%(399) of fistula patients owned nothing valuable. Of 279 patients delivered at home 186 were those who owned nothing. Out of 180-fistula patients mentioned distance as the major problem, 103 (57%) stayed at home for delivery. About 54% of fistula patients were already divorced on arrival to the hospital and this figure varied among women with different parity and among those owning different property. Teenage and short stature are observed features of fistula patients. The study also showed the huge problems faced by fistula patients in accessing emergency obstetric care services. Analytic study is recommended to compare the magnitude of these problems among other mothers with different obstetric outcome. Meanwhile, community education about problems following teenage pregnancy, sign and symptoms of obstructed labor and the advantage of institutional delivery might reduce the occurrence rate of obstetric fistula. Community organized fund and maternity waiting areas for young and short expecting mothers are among other recommendations to be considered. PMID:15884272

    Introduction Complex anal fistulas are responsible for pain, faecal incontinence and impaired quality of life. The rectal mucosa advancement flap (RMAF) procedure to cover the internal opening of the fistula remains a strategy of choice. However, a new procedure for closing anal fistulas is now available with the use of a nitinol closure clip (OTSC Proctology, OVESCO), which should ensure a better healing rate. This procedure is currently becoming more widespread, though without robust scientific validation, and it is therefore essential to carry out a prospective evaluation in order to determine the efficacy and safety of this new medical device for complex anal fistulas. Methods and analysis The FISCLOSE trial is aimed at evaluating the efficacy and safety of a nitinol closure clip compared to the RMAF procedure for the management of complex anal fistulas. This trial is a prospective, randomised, controlled, single-blind, bicentre and interventional study. Patients (n=46 per group) will be randomly assigned for management with either a closure clip or RMAF. The main objectives are to improve the healing rate of the anal fistula, lessen the postoperative pain and faecal incontinency, enhance the quality of life, and lower the number of reinterventions and therapeutic management costs. The primary outcome is the proportion of patients with a healed fistula at 3 months. The secondary outcomes are anal fistula healing (6 and 12 months), proctological pain (visual analogue scale), the faecal incontinence score (Jorge and Wexner questionnaire), digestive disorders and quality of life (Gastrointestinal Quality of Life Index and Euroqol EQ5D-3 L) up to 1 year. Ethics and dissemination The study was approved by an independent medical ethics committee 1 (IRB00008526, CPP Sud-Est 6, Clermont-Ferrand, France) and registered by the competent French authority (ANSM, Saint Denis, France). The results will be disseminated in a peer-reviewed journal and presented at

    The transradial artery approach to angioplasty has rarely been reported as a method for treating dysfunctional Brescia-Cimino fistulas. This study evaluated the feasibility, safety, and 1-year efficacy of this method for treating dysfunctional Brescia-Cimino fistulas. We retrospectively evaluated 154 consecutive procedures in 131 patients (age, 58.3 {+-} 11.6 years; male, 48.1%) who underwent the transradial approach in dysfunctional Brescia-Cimino fistulas in the 1-year period after the procedure. The operator determined the use of a regular or a cutting balloon (two cases) in combination with urokinase injection (one case) or catheter thromboaspiration. Radial artery puncture was successful in all cases. Fifty-two cases (33.8%) had totally occluded fibrotic lesions. The overall anatomic success rate and clinical success rate were 61% (94/154) and 81.1% (125/154), respectively. In cases with a totally occluded fibrotic lesion, the clinical success rate was 46%. Successful intervention was associated with a significant reduction in the radial arterial systolic and diastolic pressures. There were no complications of symptomatic arterial embolization or pulmonary embolism, and one complication of venous rupture was successfully treated by compression. The primary patency rates based on intention-to-treat were 75.3% at 30 days and 39.0% at 1 year after the procedure. Excluding the cases with a totally occluded lesion, the clinical success rate was 99% (101/102) and the primary patency rates were 84.3% (86/102) and 52.0% (53/102) at 3 months and 1 year after the procedure, respectively. In conclusion, the transradial approach is a feasible, safe, and effective alternative for catheter intervention for dysfunctional Brescia-Cimino fistulas. Its success rate in cases with a totally occluded fibrotic lesion is unsatisfactory.

    We reviewed records of 86 consecutive fistula explorations over 12 years. Four cases were children under age 18. There were 35 fistulas, all in adults. Since this series, we have identified five more children with fistula explorations for a total of nine patients. Two had bilateral explorations. Presenting symptoms were hearing loss and dizziness. None of the children had a definite fistula. Of the nine patients, one patient had a significant improvement in hearing postoperatively, five had no change, and two had worse hearing. There was no follow-up in two patients or in the second ear of a bilateral case. We feel that a fistula should be considered in any case of progressive or fluctuating sensorineural hearing loss, especially in cases with a congenital inner ear deformity. In such cases, an exploration may be reasonable to rule out a fistula. Otherwise, we are hesitant to explore patients for fistulas regardless of whether they are children or adults. Sudden, progressive, and fluctuating sensorineural hearing loss, dizziness, and meningitis have been attributed to perilymph fistulas in both adults and children. The literature reports fistulas in all types of conditions. The incidence and degree of success of treatment have varied widely. When Goodhill first reported round window rupture as a cause of sudden sensorineural hearing loss (SNHL), the Otologic Medical Group (OMG) began routine exploration of all cases of sudden SNHL for the presence of fistulas. After 50 consecutive cases were explored and no fistulas were found, we became selective in our exploration candidates.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2610242

    Purpose. To carry out a systematic review of randomized trials comparing surgery vs. endovascular therapy for occluded fistulas and grafts. Methods. All randomized trials which compared surgery and endovascular therapy for occluded fistulas and grafts were retrieved from 1990 onwards. The following search terms were used: 'haemodialysis,' 'thrombosis,' 'arteriovenous fistula,' 'arteriovenous shunt,' 'end stage renal failure' on Medline and PubMed. The results of the pooled data were analysed by a fixed-effect model. Results. There were no randomized trials comparing surgery vs. endovascular therapy for native fistulas and vein grafts. Six randomized studies reporting on 573 occluded grafts were identified. Technical success, need for access line and primary patency at 30 days were similar between the two groups (odds ratio [OR] 1.40, 95 % confidence interval [CI] 0.91-2.14; OR 0.77, 95 % CI 0.44-1.34; and OR 1.15, 95 % CI 0.79-1.68, respectively). There was no significant difference in morbidity at 30 days between groups (OR 1.12, 95 % CI 0.67-1.86). There were no statistical difference between the two groups for 1 year primary patency (OR 2.08, 95 % CI 0.97-4.45). Primary assisted patency at 1 year was better with surgery (OR 3.03, 95 % CI 1.12-8.18) in a single study. Conclusion. Comparable results to surgery have been achieved with endovascular techniques for occluded prosthetic grafts for dialysis access. Long-term data comparing the two groups were lacking. Further trials designed to encompass variation in methods are warranted in order to obtain the best available evidence particularly for native fistulas.

    Congenital pulmonary arteriovenous fistula is frequently associated with hereditary haemorrhagic telangiectasia (Rendu-Osler-Weber disease). With the increased blood flow in pregnancy such fistulas enlarge, occasionally giving rise to haemothorax, which generally has a poor prognosis. A familial case is presented in which massive haemothorax required emergency thoracotomy in the 27th week of pregnancy.

    1998-07-01

    Textual and contextual evidence suggests that the French king's fistula, a central plot device in Shakespeare's play All's Well That Ends Well, is a fistula-in-ano. Anal fistula was known to the lay public in Shakespeare's time. In addition, Shakespeare may have known of the anal fistula treatise of John Arderne, an ancestor on Shakespeare's mother's side. Shakespeare's use of anal fistula differs from all previous versions of the story, which first appeared in Boccaccio's Decameron and from its possible historical antecedent, the fistula of Charles V of France. This difference makes sense given the conventions of Elizabethan comedy, which included anal humor. It is also understandable when one looks at what wounds in different locations mean in European legend. In this light, it is not surprising that subsequent expurgations treat Boccaccio's and Shakespeare's fistulas differently, censoring only Shakespeare's. This reading has implications for the staging of All's Well That Ends Well, and for our view of the place of anal fistulas in cultural history.

    We report a case of a venous aneurysm secondary to an acquired ileocolic arteriovenous fistula in a 64-year-old woman with recurrent abdominal pain and history of appendectomy. The aneurysm was diagnosed by ultrasound and computed tomography. Angiography showed an arteriovenous fistula between ileocolic branches of the superior mesenteric artery and vein. This vascular abnormality was successfully treated with coil embolization.

    Congenital coronary pulmonary artery fistula (CAF) is rare, and systemic-to-pulmonary artery fistula (SPAF) is even more so. Furthermore, congenital coronary pulmonary fistula associated with congenital SPAF is extremely rare. As far as we know, CAF and SPAF connected with an aneurysm have not been described very often. We described an 83-year-old woman with an aneurysm originating from a CAF connected to an aortopulmonary artery fistula. Chest radiography revealed a shadow at the left edge of the heart line. Multi-detector-row computed tomography (MDCT) with contrast enhancement and coronary cine angiography revealed that the shadow was an aneurysm connected to a tortuous fistula at the left anterior descending coronary artery. The aneurysm was formed by congenital coronary pulmonary and aortopulmonary artery fistulae. Echocardiography revealed predominantly systolic blood flow in the fistula from the left anterior descending coronary artery (LAD). Although neither MDCT, echocardiography nor coronary angiography alone could provide a comprehensive image of the anomaly, including the hemodynamics in the fistulae and their relationship with surrounding organs and tissues, their combination could provided important facts the led to a deeper understanding of this very uncommon occurrence.

    Enterocutaneous fistula is the most common of all intestinal fistulas. Is a condition that requires prolonged hospital stay due to complications such as electrolyte imbalance, malnutrition, metabolic disorders and sepsis. Nutritional support is an essential part of the management; it favors intestinal and immune function, promotes wound healing and decreases catabolism. Despite the recognition of the importance of nutrition support, there is no strong evidence on its comprehensive management, which can be limiting when establishing specific strategies. The metabolic imbalance that a fistula causes is unknown. For low-output fistulas, energy needs should be based on resting energy expenditure, and provide 1.0 to 1.5 g/kg/d of protein, while in high-output fistulas energy requirement may increase up to 1.5 times, and provide 1.5 to 2.5 g/kg of protein. It is suggested to provide twice the requirement of vitamins and trace elements, and between 5 and 10 times that of Vitamin C and Zinc, especially for high-output fistulas. A complete nutritional assessment, including type and location of the fistula, are factors to consider when selecting nutrition support, whether is enteral or parenteral nutrition. The enteral route should be preferred whenever possible, and combined with parenteral nutrition when the requirements cannot be met. Nutritional treatment strategies in fistulas may include the use of immunomodulators and even stress management.

    Perianal fistula is a clinical entity with multiple surgical treatment options. Recently, magnetic resonance imaging (MRI) has emerged as an important imaging modality in the management of perianal fistulas. It provides accurate description of the fistula within the anal canal in relation to the sphincter complex and other pelvic floor structures as well as the associated complications such as abscess. By understanding the surgical viewpoint, the appearance of perianal fistulas, associated complications, and post-treatment findings of commonly used surgical interventions can more accurately be interpreted to aid clinicians. The objective of the article is to review MRI indications and findings, radiological versus surgical classification schemes, and surgical treatment options for perianal fistulas. PMID:23242265

    A 7-year-old warmblood mare showed sudden onset of mild intermittent haemoptysis. Clinical examination revealed no significant abnormalities. Haematological examination showed mild anaemia, hypoalbuminaemia and neutrophilia. Coagulation tests were normal. Endoscopic examination revealed unilateral pulmonary haemorrhage with blood clots in the bronchi and trachea. Treatment with antibiotics was started and the horse was given stable rest. Two weeks later, the horse was found dead with blood and frothy sputum leaking from the nostrils. Post-mortem examination revealed a large thoracic aortic aneurysm communicating with a pseudoaneurysm that had formed a fistula into a right bronchial branch. Microscopical examination of the aneurysm showed extensive medial fibrosis with prominent degeneration, fragmentation and mineralization of the elastic fibres and deposition of mucoid material in the tunica media. The pseudoaneurysm was lined by collagen bundles admixed with fibroblasts and a small amount of adipose tissue. Aortobronchial fistula is a rare condition in man that is usually associated with primary aortic pathology, most often aneurysms. To the authors' knowledge this is the first case of a fatal aortobronchial fistula in a horse or any other animal species. PMID:27535296

    The objective of this retrospective study was to present the authors' experience on the management of labyrinthine fistula secondary to cholesteatoma. 695 patients, who underwent tympanoplasty for cholesteatoma, in a University Hospital between 1993 and 2013 were reviewed, to select only those with labyrinthine fistulas. 42 patients (6%) had cholesteatoma complicated by fistula of the lateral semicircular canal (LSCC). The following data points were collected: symptoms, pre- and postoperative clinical signs, surgeon, CT scan diagnosis, fistula type, surgical technique, preoperative vestibular function and audiometric outcomes. Most frequent symptoms were unspecific, such as otorrhea, hearing loss and dizziness. However, preoperative high-resolution computed tomography predicted fistula in 88 %. Using the Dornhoffer and Milewski classification, 16 cases (38 %) were identified as stage 1, 22 (52 %) as stage II, and 4 (10 %) as stage III. The choice between open or closed surgical procedure was independent of the type of fistulae. The cholesteatoma matrix was completely removed from the fistula and immediately covered by autogenous material. In eight patients (19 %), the canal was drilled with a diamond burr before sealing with autologous tissue. After surgery, hearing was preserved or improved in 76 % of the patients. There was no statistically significant relationship between the extent of the labyrinthine fistula and the hearing outcome. In conclusion, a complete and nontraumatic removal of the matrix cholesteatoma over the fistula in a one-staged procedure and its sealing with bone dust and fascia temporalis, with sometimes exclusion of the LSCC, is a safe and effective procedure to treat labyrinthine fistula.

    In African American hemodialysis patients, the prevalence of autogenous arteriovenous fistula (AVF) use is lower yet AVF complications are higher. However, the adequacy and survival rates of AVF in African American patients have not been clarified. These rates were evaluated in this study. A prospective surveillance of AVF was conducted at the Morehouse School of Medicine affiliated dialysis units. A database was generated to adequately document the dates of AVF creation, cannulation, and failure; anatomic fistula sites; and demographic and pertinent clinical information. A total of 167 AVF were created in 140 African American patients between 1997 and 2001. The mean age of the patients was 56 +/- 14 (21-83) years, and the mean duration of follow-up was 40 +/- 3 (1-200) weeks. Only 92 of 167 (55%) AVF were adequate for cannulation; 12% (20 of 167) failed to mature and 33% (55 of 167) developed early failure. Unassisted primary patency rates at 6 and 12 months were 85% and 61%, respectively. Both fistula adequacy and survival were greater in younger (aged < 65 years), male patients and in nondiabetic patients, but the differences were not significant. Logistic regression analysis showed that advanced age (> or = 65 years), female gender, and diabetic state did not significantly alter AVF adequacy. However, the presence of peripheral vascular disease adversely affected AVF adequacy [Odds Ratio 0.4 (confidence interval 0.2-1.0), p = 0.048]. The adequacy and survival rates of AVF in African Americans are comparable with those reported in other populations. Fistula adequacy and survival appear to be independent of ethnicity but dependent on individual comorbid conditions and the integrity of the vasculature. Discriminant AVF site selection and adequate preoperative assessment of the vasculature remain crucial to AVF survival.

    A 61-year-old woman visited our hospital complaining of right flank pain and fever. The radiograph demonstrated multiple renal calculi. Radio renography showed no uptake in the right kidney. Therefore, we diagnosed her with pyonephrosis, and recommended open nephrectomy. However, she selected the conservative treatment with extra corporeal shockwave lithotripsy (ESWL). In spite of disappearance of multiple calculi, pyuria continued for 3 months after ESWL. Retrograde pyelography showed a fistula from the right pelvis into the duodenum. The patient was successfully treated by nephrectomy and duodeno-fistelectomy.

    Arteriovenous fistulae are surgically created to provide adequate access for dialysis patients suffering from end-stage renal disease. It has long been hypothesized that the rapid blood vessel remodeling occurring after fistula creation is, in part, a process to restore the mechanical stresses to some preferred level, i.e., mechanical homeostasis. We present computational hemodynamic simulations in four patient-specific models of mature arteriovenous fistulae reconstructed from 3D ultrasound scans. Our results suggest that these mature fistulae have remodeled to return to ''normal'' shear stresses away from the anastomoses: about 1.0 Pa in the outflow veins and about 2.5 Pa in the inflow arteries. Large parts of the anastomoses were found to be under very high shear stresses >15 Pa, over most of the cardiac cycle. These results suggest that the remodeling process works toward restoring mechanical homeostasis in the fistulae, but that the process is limited or incomplete, even in mature fistulae, as evidenced by the elevated shear at or near the anastomoses. Based on the long term clinical viability of these dialysis accesses, we hypothesize that the elevated nonhomeostatic shear stresses in some portions of the vessels were not detrimental to fistula patency.

    Coronary artery fistulae represent the most frequent congenital anomalies of the coronary arteries, but remain a relatively uncommon clinical problem. Moreover, multiple fistulae originating from both the left and the right coronary arteries and draining into the left ventricular chamber are a rare condition. Due to the low prevalence of these anomalies, the appropriate management of patients with symptomatic coronary artery fistulae is controversial. Transcatheter closure approaches have emerged as a less invasive strategy and are nowadays considered a valuable alternative to surgical correction with similar effectiveness, morbidity and mortality. The percutaneous management, however, is mainly limited by the individual anatomic features of the fistula and an appropriate patient's selection is considered as a key determining factor to achieve complete occlusion. Thus, success rates of transcatheter closure techniques reported in the literature are extremely variable and highly dependent upon the nature of the follow up, which, at present, is not standardized. The optimal management of symptomatic patients with multiple coronary artery fistulae still remains a challenging problem and has been traditionally considered as an indication for cardiac surgery. We report here the case of a patient with double bilateral congenital coronary artery fistulae arising from both the left and right coronary arteries and draining individually into the left ventricular chamber. This patient underwent successful transcatheter anterograde closure of both fistulae using a microcoil embolization technique.

    Bronchobiliary fistula is a rare and is an uncommon but severe complication of hydatid disease of the liver. Treatment has traditionally been surgical resection, but embolization and stent placement have been described. The invasive method seems to be a key component of patient treatment. We describe a case of a 58-year-old woman who, 25 years before, had undergone surgery for a hydatid cyst. A total cystectomy without previous puncture or parasite extraction was carried out. The lower aspect of the cyst was found to be completely perforated over the biliary duct. During the postoperative course, the patient had subphrenic right-sided pleural effusion and biliary fistula that subsided with medical treatment. Afterward, the patient came to the outpatient area of our hospital complaining of leakage of purulent exudate through the cutaneous opening, pain located on the right hypochondrium radiating to the right hemithorax, malaise, fever, chronic cough, and occasional vomiting of bile. Fistulography revealed an anfractuous cavity communicating with a residual cystic cavity on the right hepatic lobe. We observed communication with the intrahepatic canaliculi. Computed tomographic scan revealed a fistulous tract on the anterior liver border through the abdominal wall. There were no posttreatment complications. The patient is asymptomatic.

    Purpose. The carotid-cavernous fistula (CCF) is an abnormal arteriovenous communication and its drainage pathways may affect the clinic presentation and change treatment approach. We evaluated drainage patterns of CCFs by digital subtraction angiography (DSA) and categorized drainage pathways according to their types and etiology. Materials and Methods. Venous drainage patterns of 13 CCFs from 10 subjects were studied and categorized as anterior, posterior, superior, inferior, and contralateral on DSA. Drainage patterns were correlated to types and etiology of CCFs. Diagnosis of CCFs was first made by noninvasive imaging techniques. Results. On DSA, traumatic CCFs were usually high flow, direct type while spontaneous CCFs were usually slow flow, indirect type. Bilaterality and mixed types were observed among the indirect spontaneous CCFs. In all CCFs, anterior and inferior drainages were the most common. Contrary to the literature, posterior and superior drainages were noted only in high flow and long standing direct fistulas. Contralateral drainage was not observed in all, supporting plausible compartmentalization of cavernous sinuses. Conclusion. Types, etiology, and duration of the CCFs may affect their drainage patterns. DSA is valuable for categorization of CCFs and verification of drainage patterns. Drainage pathways may affect the clinic presentation and also change treatment approach. PMID:24967298

    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. PMID:26875638

    The management of labyrinthine fistula is a controversial issue. Hearing preservation represents a major challenge. Retrospective study of 31 patients with labyrinthine fistula confirmed intra-operatively during cholesteatoma surgery. In all cases, total matrix removal was performed, and the fistula covered with bone dust, periostium and/or cartilage. Twenty-five patients received a high intra-operative dosage (500 mg) of intravenously applied steroids at least 15 min before handling the fistula. Outcome measurements included comparison of the pre-operative and post-operative bone conduction to assess inner ear function. The results were, the fistula was located in the lateral semicircular canal (LSC) in 22 patients (71.8%) and in the oval window in eight. One patient had a double localization in the superior and lateral semicircular canals. Out of the LSC fistulas, five patients (16.12%) had a fistula type I, 8 had type IIa (25.8%), four (12.9%) type IIb, and six patients type III (19.35%). Three out of eight patients with fistula located in the oval window had a total absence of the footplate, other four presented a partial anterior resorption at the level of the fissula antefenestram and the remaining one had a fractured platina. Pre-operatively, the bone conduction displayed a mean threshold of 35 dB. Twenty-two (85%) out of 26 patients treated intra-operatively with steroids showed preservation or improvement of bone conduction. Patients with fistulas of the oval window, type I, IIa and III fistulas in the LSC treated with cortisone presented good sensorineural hearing outcome (preservation or significant improvement of inner ear function in the majority of cases-91%); the auditory results for group IIb were inconclusive. Five patients did not receive steroids, four of them developed partial sensorineural hearing loss and one went deaf. To conclude, cholesteatoma surgery with a single-staged matrix removal on perilymphatic fistulas, after intra

    A parotid fistula is a rare, extremely unpleasant disease. It may be due to chronic pathologies of the facial soft tissues, trauma (tangential injury to face), infection or congenital. Various treatment modalities including surgical and conservative management are present to treat this disease. Conservative management plays a vital role in patients who are systemically compromised and unfit for surgery. In the present case report an alternative conservative technique of parotid fistula management has been described in a 28-year-old girl who was severe anemic with parotid fistula since last 25 yrs.

    Postirradiation rectovaginal fistula is a complex problem in colorectal surgery. The modified Parks procedure curettage of rectal mucosa heavily damaged by radiation is introduced. Fifteen cases of coloanal sleeve anastomosis for the repair of rectovaginal postirradiation fistula are described. All patients previously were irradiated heavily because of carcinoma of the uterine cervix. Three patients had simultaneous repair of vesicovaginal fistula. One postoperative death was observed. Of the surviving patients, functional results have been good in 11. In the seven patients with difficult stripping of the rectal mucosa, surgical curettage was performed. The latter procedure is suggested as the method of choice in relevant cases.

    Oroantral and oronasal fistulas present with a broad range of causation, size, duration, and extent of infection involving the nose and paranasal sinuses. Accurate diagnosis of the extent of the disease with appropriate radiographic evaluation will guide the surgeon to select an approach that addresses all of the infected sites. When significant sinus disease is found, an endoscopic approach to restoring drainage in all of the involved sinuses can promote predictably successful closure of oroantral and oronasal fistulas. The multispecialty team approach to this disease, with the concomitant management of the sinusitis and fistula closure, is a significant advance in the successful management of this chronic condition.

    Abstract Gastrointestinal (GI) fistula is a well-recognized complication of acute pancreatitis (AP). However, it has been reported in limited literature. This study aimed to evaluate the incidence and outcome of GI fistulas in AP patients complicated with infected pancreatic or peripancreatic necrosis (IPN). Between 2010 and 2013 AP patients with IPN who diagnosed with GI fistula in our center were analyzed in this retrospective study. And we also conducted a comparison between patients with and without GI fistula regarding the baseline characteristics and outcomes. Over 4 years, a total of 928 AP patients were admitted into our center, of whom 119 patients with IPN were diagnosed with GI fistula and they developed 160 GI fistulas in total. Colonic fistula found in 72 patients was the most common form of GI fistula followed with duodenal fistula. All duodenal fistulas were managed by nonsurgical management. Ileostomy or colostomy was performed for 44 (61.1%) of 72 colonic fistulas. Twenty-one (29.2%) colonic fistulas were successfully treated by percutaneous drainage or continuous negative pressure irrigation. Mortality of patients with GI fistula did not differ significantly from those without GI fistula (28.6% vs 21.9%, P = 0.22). However, a significantly higher mortality (34.7%) was observed in those with colonic fistula. GI fistula is a common finding in patients of AP with IPN. Most of these fistulas can be successfully managed with different procedures depending on their sites of origin. Colonic fistula is related with higher mortality than those without GI fistula.

    Chyle fistula is an uncommon serious complication of neck surgery, occurring in 1-3% of radical neck dissections. An untreated chyle leak is a potentially dangerous condition that may rarely lead to hypovolemia, hyponatremia, hypochloremia, hypoproteinemia and lymphopenia. Anatomic variants of the terminal portion of the thoracic duct and suction drainage in the neck wound play a primary role in causing this kind of lesion. Poor is the literature concerning chyle fistula, due to its rarity, and mostly case reports; still debated--prevalently empiric--is the management of this disease. The Authors report a case of chyle fistula following a reintervention of cervical bilateral lymphectomy for medullary carcinoma of the thyroid in a 75 years old female. In the reported case the chyle fistula was successfully treated conservatively, in early post-operative period with a low-fat diet and total parenteral nutrition, definitely followed by sclerosant therapy. The injection of a sclerosant agent (4 g of sterile medical talc diluted in isotonic sodium chloride solution) into the supraclavicular wound bed, through the drainage tube (clamped for 2 hours), determined rapid decline in fistula output, hence obviating surgical intervention.

    BACKGROUND: Enterocutaneous fistulae (ECFs) after typhoid perforation have been previously recorded postoperatively due to repair leak or new perforation. Spontaneous ECF formation due to primary intra-abdominal pathologic processes has been attributed to infectious diseases such as tuberculosis and Crohn's disease. A review of the literature has shown no previous report of spontaneous ECF caused primarily by salmonella typhi infection. OBJECTIVE: To report a case of spontaneous ECF due to salmonella typhi infection. CASE REPORT: An eight-year-old female presented with high fever and weight loss of two weeks' duration and a one-week history of a foul-smelling umbilical discharge. She was ill looking, wasted, with evidence of peritonitis. An emergency exploratory laparotomy revealed multiple perforations at the antimesenteric border of the ileocecal valve. With intestinal resection and anastomosis and the use of broad spectrum antibiotics, her clinical state improved. Tissue biopsy showed hemorrhagic necrosis with infiltration by mononuclear inflammatory cells. CONCLUSION: ECF is a rare complication of enteric fever, Enteric fever should therefore be considered in ill children presenting with ECF in the absence of a history of previous surgery, or blunt or penetrating trauma.

    Aortoenteric fistula is an uncommon but life-threatening cause of gastrointestinal blood loss. We report a case of a 70-year-old man who presented to the emergency department with an episode of melena and infection in the left inguinal region. Diagnosis of secondary aortoenteric fistula was made between the left limb of the aortobifemoral graft and the descending colon. We performed excision of the infected graft and in situ silver acetate coating of prosthetic vascular graft replacement (aortoleft femoral) on the patient. This study reports a rare type of secondary aortoenteric fistula to the left colon, and it describes an unusual and successful surgical treatment. Antimicrobial coating of prosthetic vascular grafts may be a good alternative in the presence of graft infection associated with aortoenteric fistula because in situ grafts may carry an increased risk of reinfection.

    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. PMID:24976737

    Anal fistulas are a common manifestation of Crohn’s disease (CD). The first manifestation of the disease is often in the peri-anal region, which can occur years before a diagnosis, particularly in CD affecting the colon and rectum. The treatment of peri-anal fistulas is difficult and always multidisciplinary. The European guidelines recommend combined surgical and medical treatment with biologic drugs to achieve best results. Several different surgical techniques are currently employed. However, at the moment, none of these techniques appear superior to the others in terms of healing rate. Surgery is always indicated to treat symptomatic, simple, low intersphincteric fistulas refractory to medical therapy and those causing disabling symptoms. Utmost attention should be paid to correcting the balance between eradication of the fistula and the preservation of fecal continence. PMID:25309057

A nulliparous 19-year-old female presented with a 3-week history of a foreign body in the vagina causing urinary incontinence and offensive vaginal discharge. Her guardian allegedly inserted the foreign body after she refused a pre-arranged marriage. A plastic container was removed from the vagina under general anesthesia. A large vesico-vaginal fistula was discovered, which was successfully surgically repaired. We recommend urgent removal of the foreign body, preferably under general anesthesia. However, if the history or physical examination reveals prolonged exposure, repair of the fistula should be delayed to allow for adequate debridement in order to prevent any life-threatening complications.

    Summary We describe a case of arteriovenous fistula (AVF) successfully treated by coil embolization with an anchor coil inserted in the varix to facilitate dense packing at the shunting site. AVF of the left anterior choroidal artery (AChoA) draining into the ipsilateral basal vein of Rosenthal was incidentally found in a newborn female. A single detachable coil was inserted as an anchor into the varix adjacent to the shunt, and the microcatheter was pulled back to the shunting point. Three more detachable coils were delivered at the shunting point without migration under the support of the anchor coil, and the AVF was successfully obliterated with preservation of AChoA blood flow. The anchor coil technique can reduce the risk of coil migration and the number of coils required. PMID:24976089

    Second reason for consultations in proctology in our department after hemorroïds-linked illnesses, fistulas in ano constitute a chronic disease which causes therapeutic difficulties linked mainly to the futur functionning of the sphincter, especially in its most complex types. In our group of 43 patients in whom surgical exploration with stylet was the key of the diagnosis, the anorectoscopy and even less chirurgical examination were not often contributive, the fear of post-operative incontinence forced us to prefer ligation-section with rubber every time that the sphincter was involved. With our results, the majority of patients (41/43) healed in normal periods with a sufficient functionning of the anus. This result confirmed our attitude towards the sphincter: that is to save if possible.

    Introduction Primary aortoenteric fistula (PAEF) is a pathological communication between the aorta and any portion of the gastrointestinal tract. The pathology is very rare and easily overlooked during the diagnostic process. Presentation of Case We report the exceptional case of an 86-year-old man with episodes of abdominal pain and rectal bleeding of unknown cause over a period of 1,5 months due to a PAEF to the sigmoid. A sigmoidectomy was performed and a rifampicin-soaked aortic graft was placed. The patient had an uneventful post-operative recovery. The duration of symptoms, the anatomic location of the fistula and the outcome after surgery makes this case unique. Discussion With an incidence of 0.04–0.07% in all patients with aortic aneurysms a PAEF is very rare. Only 2% of PAEF's involves the sigmoid. The most common cause is an atherosclerotic aortic aneurysm. Patients with PAEF can present with a triad of symptoms including gastrointestinal bleeding, abdominal pain and a pulsating mass. A contrast-enhanced computer-tomography scan (CTa) is the most accurate tool to demonstrate a PAEF. Without a strong clinical suspicion, diagnosing a PAEF is hard and frequently delayed. The overall PAEF-related mortality is high (61–100%) and decreases after surgery (30–40%). Conclusion A primary aortoenteric fistula involving the sigmoid is very rare. Clinical presentation can vary, diagnosis can be difficult and surgical options may differ. Even with low suspicion of PAEF, we recommend performing a CTa. With a high overall mortality of more than 60% due to exsanguinating, surgical treatment is always indicated. PMID:26741274

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

    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.

  7. A two-layer closure of sino-orbital fistula.

    PubMed

    1989-11-01

    A two-layer closure of sino-orbital fistulae using tension-free local flaps is described. For small fistulae, the opening is first closed with a mucosal turnover flap; this is combined on the orbital surface with a local rotational advancement flap of the orbital skin. For larger fistulae where a mucosal turnover flap cannot be fashioned, a two-stage, delayed, composite mucocutaneous rotational flap is used. The advantages of these techniques are: (1) a mucous membrane to provide nasal or sinus lining, insulating the raw ventral surface of the skin flap; (2) each flap has an independent blood supply; (3) local flaps are used, avoiding the use of a pedicle flap from forehead; (4) excellent cosmesis since tissues outside the orbital rim are not disturbed; and (5) does not require refitting of exenteration prosthesis since the integrity of the orbital rim is maintained. The authors have used these techniques in six patients with chronic sino-orbital fistulae of the exenterated socket. In one patient, a wound dehiscence occurred and a small fistula measuring 3 to 4 mm in diameter persisted. The fistulae of the remaining five patients were successfully closed.

    Background An increased incidence of nasolacrimal duct fistula in the offspring of dam J and three of her sons (bulls A, B and C) prompted a study to investigate the prevalence and clinical manifestation of this anomaly. The dam J, bull B, 255 direct offspring of bulls A, B, and C and eight other direct and indirect offspring of cow J were examined. The periocular region of each animal was examined for unilateral or bilateral nasolacrimal duct fistula and the location, appearance and size of the lesions. Results Of 265 cattle examined, 54 had unilateral (n = 24) or bilateral fistula (n = 30). The prevalence of affected offspring differed significantly among the three bulls. The fistulae were located medial to the medial canthus of the eye and were 1 to 10 mm (median, 1 mm) in height and 1 to 12 mm (median, 2 mm) in length. The shape of the opening was circular in 58, oval in 23 and slit-like in three. One other animal had a large opening with an atypical shape and another had an abnormal medial canthus with several fistulous openings. Seventy openings were pigmented and 52 were hairless. The fistulae were clinically significant in 12 animals. Conclusions The findings suggest a hereditary cause of nasolacrimal duct fistula in Brown Swiss cattle. PMID:24548799

    We present a case of an aortocaval fistula (ACF) without bleeding because a clot was covering the fistula. A 60-year-old man was diagnosed as having a ruptured abdominal aortic aneurysm (AAA) and an aortocaval fistula, by enhanced computed tomography (CT). After the aneurysm had been opened, the fistula was detected, but there was no bleeding because it was covered with clot. After graft repair, bleeding from the fistula occurred when the clot was removed by suction. Direct closure of the fistula was achieved after bleeding was controlled by digital compression.

    The purpose of this study was to assess the value of percutaneous transluminal angioplasty (PTA) for the salvage of arteriovenous fistulas (AVFs) that fail to mature. From November 1998 to February 2003, 19 patients who were treated with PTA due to immature forearm AVFs were selected. Fistulography and PTA were performed via a retrograde transvenous approach after direct puncture of the fistular vein. Technical success was defined as less than a 30% residual stenosis, whereas clinical success was defined as the ability to perform at least one session of normal hemodialysis after PTA. Findings of fistulograms, success rates of PTA, and patency rates were evaluated. On initial fistulograms, stenoses were observed in all cases and 68% (13/19) of the stenoses were located in the perianastomotic area of these immature AVFs. The initial technical success rate was 84% (16/19). Technical failures comprised two patients with diffuse narrowing and segmental thrombosis of the cephalic veins and one case of elastic recoil of the anastomotic site stenosis after PTA. Two patients were immediately lost on follow-up. The remaining 14 cases underwent successful hemodialysis 0 to 33 (mean = 15) days after PTA, showing 74% (14/19) clinical success. Although accessory branch veins were noted in most cases (74%, 14/19), leaving them alone did not affect the maturation of AVFs following PTA. There was no significant procedural or late complication. Primary and secondary patency rates at 1 year were 61 and 82%, respectively. For those AVFs that failed to mature, there were stenoses along their vascular courses as underlying causes. For the percutaneous procedure, the retrograde transvenous approach was a reasonable one. As PTA is effective and quick for the salvation of immature AVFs, it can be considered a primary method for salvaging these immature AVFs.

    Background To compare outcomes of open and endovascular repair of aortocaval fistulas (ACFs) in the setting of abdominal aortic aneurysms (AAAs). Methods A literature review was undertaken on Pubmed from 1999 to 2014 to identify reported cases of both endovascular and open repair of ACF, including the index case, presented here. Primary outcomes for endovascular repair were: complications, presence of endoleak, and death. Primary outcomes for open repair were: complications and death. Results Forty articles were reviewed with a total of 67 patients, including the index case. Endovascular approach was used in 26 patients (39%). Endoleaks were present in 50%, whereas similarly 46% of patients had a reported complication. Five deaths (19%) occurred in the endovascular group. Open repair was performed in 41 cases (61%). The rate of complication and the death in open repair were 36% and 12%, respectively (P = 0.327 and P = 0.910, respectively) compared with endovascular. Mean follow-up was 7.7 months for the endovascular group and 8.5 months in the open group. Conclusions Previous demonstrations of high morbidity and mortality with open repair of ACF in the setting of AAA have motivated endovascular approaches. However, endoleaks are a significant problem and were present in 50% of ACF cases. The continued presence of an endoleak in the setting of an ACF may result in persistence of the ACF, unlikely thrombosis of the endoleak, and continued sac enlargement. Endovascular repair presents theoretical benefit, yet is not associated with a reduced rate of complication or death versus open repair in this contemporary review. PMID:26597238

    Summary We report our experience in treatment of traumatic direct carotid cavernous fistula (CCF) via endovascular intervention. We hereof recommend an additional classification system for type A CCF and suggest respective treatment strategies. 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

    Esophagocutaneous fistulas are a failure of the NO-system, due to NO-synthase blockage by the NOS-blocker L-NAME consequently counteracted by l-arginine and gastric pentadecapeptide BPC 157 (l-arginine fistulas. We treated rats with established cervical esophagocutaneous fistulas throughout four days (both open skin and esophageal defects, with significant leakage) with BPC 157 (parenterally and perorally) and L-NAME (blocking NO genesis) and l-arginine (NO-substrate) alone or in combination. RT-PCR investigated eNOS, iNOS, COX-2 mRNA levels in the fistulas. We evidenced a closely inter-related process of unhealed skin, esophageal defects, unhealed fistulas (up regulated eNOS, iNOS and COX2 mRNA levels), usually lethal, particularly NO-system related and therapy dependent. Generally, the course of fistula healing was accelerated either to a greater extent (with BPC 157 (in particular, less eNOS gene expression) completely counteracting L-NAME effects, in L-NAME+BPC 157 and L-NAME+l-arginine+BPC 157 groups), or to a lesser extent (with l-arginine). Conversely, the process was aggravated, rapidly and prominently (with L-NAME). In particular, BPC 157 was effective either given per-orally/intraperitoneally, in μg- and ng-regimens. Shortly, defects started to heal, with less fistula leakage and no mortality at day 4. Failure of pyloric and lower esophageal sphincter pressure was restored, with practically no esophagitis.

  14. Congenital and acquired perilymph fistula: review of the literature.

    PubMed

    Perilymph fistula is caused by an abnormal communication between the perilymph space and the middle ear. The etiology is either congenital or acquired. The congenital fistula can be associated or not with clinical symptoms or radiologically detectable abnormalities of the temporal bone. In patients presenting congenital fistula without symptoms or radiologically detectable abnormalities, little malformations of the middle ear may be detected during surgery. The acquired fistula can be caused by iatrogenic trauma, physical injury or erosion. As far as therapy is concerned, surgical treatment can be performed and the perilymph fistula thus represents one of the few causes of sensorineural hearing loss that can be treated surgically. However, the main challenge is the identification of those patients that need to undergo an exploratory tympanotomy, since there are no clinical-audiologic symptoms or radiographic indicators that can be considered pathognomonic of perilymph fistula. The aim of this review of the literature is to define the guidelines for preoperative diagnosis to indicate exploratory tympanotomy both in children and in adults. On the basis of our results, exploratory tympanotomy should be performed in patients with vertigo and/or progressive, sudden or fluctuating hearing loss in association with one or more than one of the following elements: a history of cranial trauma, radiographically detectable abnormalities of the inner ear, congenital malformations of the head, recurring meningitis, positive fistula test. The surgical treatment consists in placing a graft of temporalis fascia or tragal perichondrium and it usually results in a significant improvement of vestibular symptoms and sometimes of the hearing function as well.

  15. A review article on the diagnosis and treatment of cerebrospinal fluid fistulas and dural tears occurring during spinal surgery

    2013-01-01

    Background: In spinal surgery, cerebrospinal fluid (CSF) fistulas attributed to deliberate dural opening (e.g., for tumors, shunts, marsupialization of cysts) or inadvertent/traumatic dural tears (DTs) need to be readily recognized, and appropriately treated. Methods: During spinal surgery, the dura may be deliberately opened to resect intradural lesions/tumors, to perform shunts, or to open/marsupialize cysts. DTs, however, may inadvertently occur during primary, but are seen more frequently during revision spinal surgery often attributed to epidural scarring. Other etiologies of CSF fistulas/DTs include; epidural steroid injections, and resection of ossification of the posterior longitudinal ligament (OPLL) or ossification of the yellow ligament (OYL). Whatever the etiology of CSF fistulas or DTs, they must be diagnosed utilizing radioisotope cisternography (RIC), magnetic resonance imaging (MRI), computed axial tomography (CT) studies, and expeditiously repaired. Results: DTs should be repaired utilizing interrupted 7-0 Gore-Tex (W.L. Gore and Associates Inc., Elkton, MD, USA) sutures, as the suture itself is larger than the needle; the larger suture occludes the dural puncture site. Closure may also include muscle patch grafts, dural patches/substitutes (bovine pericardium), microfibrillar collagen (Duragen: Integra Life Sciences Holdings Corporation, Plainsboro, NJ), and fibrin glues or dural sealants (Tisseel: Baxter Healthcare Corporation, Deerfield, IL, USA). Only rarely are lumbar drains and wound-peritoneal and/or lumboperitoneal shunts warranted. Conclusion: DTs or CSF fistulas attributed to primary/secondary spinal surgery, trauma, epidural injections, OPLL, OYL, and other factors, require timely diagnosis (MRI/CT/Cisternography), and appropriate reconstruction.

    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.

    Radiation proctitis is a common complication after radiotherapy for pelvic malignant tumors. This study was conducted to assess the efficacy of novel almagate enemas in hemorrhagic chronic radiation proctitis (CRP) and evaluate risk factors related to rectal deep ulcer or fistula secondary to CRP. All patients underwent a colonoscopy to confirm the diagnosis of CRP and symptoms were graded. Typical endoscopic and pathological images, risk factors, and quality of life were also recorded. A total of 59 patients were enrolled. Gynecological cancers composed 93.1% of the primary malignancies. Complete or obvious reduction of bleeding was observed in 90% (53/59) patients after almagate enema. The mean score of bleeding improved from 2.17 to 0.83 (P<0.001) after the enemas. The mean response time was 12 days. No adverse effects were found. Moreover, long-term successful rate in controlling bleeding was 69% and the quality of life was dramatically improved (P=0.001). The efficacy was equivalent to rectal sucralfate, but the almagate with its antacid properties acted more rapidly than sucralfate. Furthermore, we firstly found that moderate to severe anemia was the risk factor of CRP patients who developed rectal deep ulcer or fistulas (P= 0.015). We also found abnormal hyaline-like thick wall vessels, which revealed endarteritis obliterans and the fibrosis underlying this disease. These findings indicate that almagate enema is a novel effective, rapid and well-tolerated method for hemorrhagic CRP. Moderate to severe anemia is a risk factor for deep ulceration or fistula.

    The colo-uterine fistula is a rare complication of diverticular disease of the colon; the literature review has shown only few well studied cases. The fistula, among the complications of the sigma diverticulitis, is 20% of the observed cases; generally, the bladder is the most involved organ, but also the skin or gut can be interested. If we consider the aetiology of the colo=uterine fistula of the observed case, the presence of the sigma locked stenosis with an endocolic pressure increase, associated with a peridiverticulitis condition, seems to have a relevant rule. The clinical symptomatology is represented by vague abdominal pain localized in particular in the left iliac cavity and by emission of blood, purulent material and stools from the vagina. The diagnosis of colo-uterine fistula is not easily reached: barium enema, Fallopian tube endoscopy and colon endoscopy not always allow to visualize in a right manner the fistula and only the oral administration of non-absorbable substances to be searched in the vaginal tampon, clear each doubt. Regarding the therapy to be carried out, we think that, colic resection en bloc with the uterus is the treatment of choice, while, in emergency, the Hartman operation is the most suitable to avoid the beginning of septic complications.

    Obstetric fistula is a complication of childbirth that often follows obstructed labor and is almost exclusive to low-resource countries. The original Global Burden of Disease Study (GBD 1990 Study) reported an incidence of 8.68 per 100000 and a prevalence of 51.35 per 100,000 for women aged 15-44 years in low-resource regions. The most cited global prevalence estimate is 2 million women. Although the global burden of obstetric fistula remains unclear, the number of women suffering from the condition is increasing, while surgical treatment remains limited. There are few experienced fistula surgeons and past surgical training approaches have been inconsistent. The Global Competency-Based Fistula Surgery Training Manual developed by FIGO and partners contains a set curriculum and, to ensure its implementation, a global strategy and training program have been developed. This paper describes key elements of the training program and its implementation. The anticipated impact of the training program is a reduction in global morbidity caused by obstetric fistula.

  4. Transitional Flow in an Arteriovenous Fistula: Effect of Wall Distensibility

    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.

    The acquired entero-cutaneous fistulas are a current problem in the field of abdominal surgery. Most of them are postoperative--after an intestinal resection and/or anastomosis. Crohn's disease and coplicated colonic diverticulosis rank second as causal factors. The risk factors for the development of an entero-cutaneous fistula and for the poor prognosis at the same time are the next: (1) Most of the patients suffer of severe main and co-exhisting diseases; (2) The presence of previous laparotomies, radion and chemotherapy, significant disturbances in the base-acid and water-electrolyte balance; (3) The fistula itself worsens these disturbances and may doom to fail the substitutional and nutritional therapy. The diagnostics of a fistula, including its location is comparatively easy. The surgical treatment plays an important role in the therapeutic scheme, especially in cases of high-output fistulas of the small intestin. At the same time the adequate total parenteral nutrition and correction of the base-acid and water-electrolyte disbalance is also very important. Recently there are some new diagnostic methods and alternatives of the basic surgical procedures, some of them quite contraversial.

    2016-01-01

    Summary Background Urethroscrotal fistula (USF) is an abnormal communication between the urethra and the scrotum. This rare abnormality may be iatrogenic or secondary to perforation of the urethra by a stone. After the passage of urine to the scrotum through the fistula, painless scrotal swelling develops, which disappears completely with manual compression, and voiding can be maintained in this way. Retrograde urethrography (RU) and voiding cystourethrography (VCU) are traditional diagnostic methods, but they have limitations, such as technical difficulties and inability to evaluate the surrounding tissues. Multidetector CT (MDCT), together with reformatted images, can provide valuable information about the surrounding tissues and associated pathologies. Case Report We present a case of a 36-year-old male patient who had painless scrotal swelling after cystolithotomy and urethral stone surgery. The patient indicated that the swelling disappeared after manual compression. A fistula between the bulbous urethra and the scrotum was discovered by MDCT. In our case, we believe that the fistula developed iatrogenically during stone excision or secondary to perforation of the urethra by a stone. Conclusions As a rare pathology, urethroscrotal fistula should be considered in men with a history of urethral stone surgery and symptoms, including painless scrotal swelling, which can be manually compressed after voiding.

    There are many ethical issues involved in medical missions to developing countries. The Current Opinion/Update "Humanitarian ventures or 'fistula tourism?': the ethical perils of pelvic surgery in the developing world" raised many concerns about surgical trips to treat obstetric fistula. Despite a lack of experience with obstetric fistula, western surgeons may still bring surgical and public health techniques that may be of value to health systems in developing countries. Emphasis should be placed on program development and assessment first. This should include not only surgical training but also help with counseling, prevention and reintegration. Participation in clinical trials should be up to the health care personnel in the country being helped, and aide should not depend on such participation. Success will likely be determined by a national effort and integration into existing health systems, not isolated "fistula champions." The appalling situation of obstetric fistula in the twenty-first century should be a wake-up call to obstetricians/gynecologists and urologists. The dictum "first do no harm" must not evolve into "first do nothing." PMID:17252312

    A uterocutaneous fistula is a rare clinical presentation that occurs following Cesarean section and other pelvic operations. There are only a few reports discussing the treatments. We describe a patient with successful surgical management and review the literature. A 25-year-old woman referred to our department 13 months after her first Cesarean section. She had a history of an abdominal mass and collection 2 months after surgery and some fistula opening with discharge from her previous incision. She had a previous surgical operation and antibiotic therapy without complete response. We performed fistulography to evaluate the tracts. In the operation — she had fistula tracts, one of which was between the uterus and skin. We debrided the necrotic tissue in the uterus, excised the fistula tracts, and drained the uterine cavity. At 8 months’ postoperative follow-up, she had no recurrence. A uterocutaneous fistula is a rare condition with many causes and needs proper investigation and timely medical and surgical management.

    Neointimal hyperplasia (NIH) and impaired dilatation are important contributors to arteriovenous fistula (AVF) failure. It is unclear whether chronic kidney disease (CKD) itself causes adverse remodeling in arterialized veins. Here we determined if CKD specifically triggers adverse effects on vascular remodeling and assessed whether these changes affect the function of AVFs. For this purpose, we used rats on a normal diet or on an adenine-rich diet to induce CKD and created a fistula between the right femoral artery and vein. Fistula maturation was followed noninvasively by high-resolution ultrasound (US), and groups of rats were killed on 42 and 84 days after surgery for histological and immunohistochemical analyses of the AVFs and contralateral femoral vessels. In vivo US and ex vivo morphometric analyses confirmed a significant increase in NIH in the AVFs of both groups with CKD compared to those receiving a normal diet. Furthermore, we found using histological evaluation of the fistula veins in the rats with CKD that the media shrank and their calcification increased significantly. Afferent artery dilatation was significantly impaired in CKD and the downstream fistula vein had delayed dilation after surgery. These changes were accompanied by significantly increased peak systolic velocity at the site of the anastomosis, implying stenosis. Thus, CKD triggers adverse effects on vascular remodeling in AVFs, all of which contribute to anatomical and/or functional stenosis.

Ophthalmologists are called to diagnose and manage the condition in cases that present with ocular features. A 73-year-old female was referred to our glaucoma center clinic. Eight years before, she had started receiving medication for glaucoma and had undergone laser iridotomy, but a satisfactory management of intraocular pressure (IOP) had not been achieved. The patient was complaining of intermittent diplopia, bilateral proptosis, and conjunctival chemosis over the past 6 months. Best-corrected visual acuity in the right (OD) and left eye (OS) was 9/10 and 10/10, respectively. Visual field testing showed slight paracentral field defects mostly in OS. IOP was 20 mm Hg in OD and 34 mm Hg in OS. We referred the patient to neuroradiology, and MRI angiography revealed a CCF with angiographic classification of Cognard grade 2. Closure of the CCF by transarterial embolization was performed in the neuroradiology department. One week following the procedure, the clinical signs of diplopia, proptosis, and conjunctival chemosis had greatly improved, and IOP was reduced to 12 mm Hg OD and 19 mm Hg in OS. Glaucoma treatment was maintained with topical brimatoprost, brinzolamide, and timolol. Owing to the risk of vision loss associated with vascular stasis, retinal ischemia, and high IOP, ophthalmologists must be aware of the clinical features of CCF and should request appropriate imaging studies such as MRI angiography in order to confirm the diagnosis and plan multidisciplinary treatment.

    This is a case of choriocarcinoma that did not regress after chemotherapy treatment. A 30-year-old female patient (gravida 2, para 2), presented to our ER with stroke and persistent mild pelvic pain 2 months after a Caesarean section. Computed tomography (CT) revealed an ischemic left hemicerebellar region and a hypervascular mass in the pelvic region. This mass was not present on routine fetal ultrasound during pregnancy. The lesion was treated by chemotherapy after closure of a foramen ovale and insertion of an inferior vena cava (IVC) filter. After that, 2 courses of EMACO (Etoposide, Methotrexate, Actinomycin D, Cyclophosphamide, and Vincristine) chemotherapy regimen were given. Posttreatment CT showed the hypervascular mass without any changes. Arteriography showed the arteriovenous fistulae that were embolized successfully with plugs, coils, and glue. Embolization was considered due to the risk of acute hemorrhagic life-threatening complications. Eight chemotherapy courses were added after embolization. Treatment by endovascular approach and reduction of the hypervascular mass can be a valuable adjunct to chemotherapy treatment of choriocarcinoma. PMID:27403360

    Pancreatic duct leaks can occur as a result of both acute and chronic pancreatitis or in the setting of pancreatic trauma. Manifestations of leaks include pseudocysts, pancreatic ascites, high amylase pleural effusions, disconnected duct syndrome, and internal and external pancreatic fistulas. Patient presentations are highly variable and range from asymptomatic pancreatic cysts to patients with severe abdominal pain and sepsis from infected fluid collections. The diagnosis can often be made by high-quality cross-sectional imaging or during endoscopic retrograde cholangiopancreatography (ERCP). Because of their complexity, pancreatic leak patients are best managed by a multidisciplinary team comprised of therapeutic endoscopists, interventional radiologists, and surgeons in the field of pancreatic interventions. Minor leaks will often resolve with conservative management while severe leaks will frequently require interventions. Endoscopic treatments for pancreatic duct leaks have replaced surgical interventions in many situations. Interventional radiologists also have the ability to offer therapeutic interventions for many leak patients. The mainstay of endotherapy for pancreatic leaks is transpapillary pancreatic duct stenting with a stent that bridges the leak if possible, but varies based on the manifestation and clinical presentation. Fluid collections that result from leaks, such as pseudocysts, can often be treated by endoscopic transluminal drainage with or without endoscopic ultrasound or by percutaneous drainage. Endoscopic interventions have been shown to be effective and have an acceptable complication rate.

    2016-09-15

    The topographical distribution of dural arteriovenous fistulas (DAVFs) was analyzed based on the embryological anatomy of the dural membrane. Sixty-six consecutive cases of intracranial and spinal DAVFs were analyzed based on the angiography, and each shunt point was identified according to the embryological bony structures. The area of dural membranes was categorized into three different groups: a ventral group located on the endochondral bone (VE group), a dorsal group located on the membranous bone (DM group) and a falco-tentorial group (FT group) located in the falx cerebri, tentorium cerebelli, falx cerebelli, and diaphragm sellae. The FT group was designated when the dural membrane was formed only with the dura propria (meningeal layer of the dura mater) and not from the endosteal dura. Cavernous sinus, sigmoid sinus, and anterior condylar confluence was categorized to VE group, which had a female predominance, more benign clinical presentations, and a lower rate of cortical and spinal venous reflux. Transverse sinus, confluence, and superior sagittal sinus belonged to the DM group. Olfactory groove, falx, tent of the cerebellum, and nerve sleeve of spinal cord were categorized to the FT group, which presented later in life and which had a male predominance, more aggressive clinical presentations, and significant cortical and spinal venous reflux. The DAVFs was associated with the layers of the dural membrane characterized by the two different embryological bony structures. The FT group was formed only with the dura propria as an independent risk factor for aggressive clinical course and hemorrhage of DAVFs. PMID:27250699

  2. Perilymph Fistula: Fifty Years of Controversy

    PubMed Central

    2012-01-01

    Perilymph fistula (PLF) is defined as a leak of perilymph at the oval or round window. It excludes other conditions with “fistula” tests due to a dehiscent semi circular canal from cholesteatoma and the superior canal dehiscence syndrome. It was first recognized in the early days of stapedectomy as causing disequilibrium and balance problems before sealing of the stapedectomy with natural tissue became routine. It then became apparent that head trauma and barotraumatic trauma from flying or diving could be a cause of PLF. Descriptions of “spontaneous” PLF with no trauma history followed. A large literature on PLF from all causes accumulated. It became an almost emotional issue in Otolaryngology with “believers” and “nonbelievers.” The main criticisms are a lack of reliable symptoms and diagnostic tests and operative traps in reliably distinguishing a perilymph leak from local anaesthetic. There are extensive reviews on the whole topic, invariably conveying the authors' own experiences and their confirmed views on various aspects. However, a close examination reveals a disparity of definitions and assumptions on symptoms, particularly, vestibular. This is an intentionally provocative paper with suggestions on where some progress might be made. PMID:23724269

    Background: Middle meningeal arteriovenous fistulas (MMAVFs) are rare lesions with a poorly established natural history. We report our experience with patients with MMAVFs who presented with intracranial hemorrhage. Methods: We reviewed our prospectively maintained endovascular database for patients with MMAVFs, who were treated by embolization during a 15-year period. Hospital and outpatient medical records and imaging studies were reviewed. Results: Nine patients with MMAVFs, who presented with intracranial hemorrhage, underwent embolization (mean age 60.3 years, range 21–76; four male and five female). Four patients presented after trauma and five after spontaneous hemorrhage. All nine patients were angiographically cured after embolization of the fistula with liquid embolic agents (n = 8) or coils (n = 1). There were no procedure-related complications. Conclusion: MMAVFs represent a rarely reported class of vascular lesions. They are typically associated with trauma, but also develop spontaneously, and may be associated with intracranial hemorrhage, which warrants classification of these lesions as high risk. Endovascular treatment is safe and effective and should be considered for these patients, particularly for those who have lesions with intracranial venous drainage. PMID:27127711

    Background The abscesses and anal fistulas represent about 70% of perianal suppuration, with an estimated incidence of 1/10000 inhabitants per year and representing 5% of queries in coloproctology. Aim To evaluate the effectiveness of the interesphincteric ligation technique of the fistulous tract in the treatment of anal fistula. Methods The records of eight patients who underwent this technique, evaluating age, gender and presence of incontinence were studied. Was named technical first-step the passage of cotton thread to promote the correct individualization of the fistula and, as the second, the surgical procedure. Results Two patients were men and eight women. The mean age was 42.8 years. Of these, seven (87.5%) had complete healing of the fistula; six were cured only with this procedure and one required additional operation with simple fistulotomy. Only one patient developed fecal incontinence which was documented by anorectal manometry. There were no deaths in this series. Conclusion The interesphincteric ligation technique of the fistulous tract proved to be effective for the treatment of anal fistula and should not be discouraged despite the occurrence of eventual fecal incontinence.

    A 72-year-old man underwent en masse lobectomy of the lower left lobe because of continued hemoptysis. We chose en masse lobectomy as a last resort because the patient had cardiopulmonary problems including chronic obstructive pulmonary disease (COPD), pulmonary hypertension, and continued hemoptysis. The patient developed a bronchopleural fistula 2 weeks later, so the Clagett window procedure was performed. After gauze exchange and cleaning of the pleural space, the Clagett window was closed using a latissimus dorsi muscle flap. He was discharged about 3 months after the initial operation. One of the most critical complications after en masse lobectomy is a bronchopleural fistula because the bronchial stump and vessel are too close to each other. The space between the bronchus and vessel can fill with tissue, such as pulmonary parenchyma or lymph nodes, which cover the fistula.

    Vascular complications of lumbar disc surgery are rare. Few cases have been reported. Arteriovenous fistulas are the most common. They are due to anatomical relationships between the last lumbar vertebrae, the corresponding discs, and the iliac vessels; degenerative lesions of the intervertebral discs facilitate instrumental vessel perforation, and operative difficulty. Computed tomography is particularly accurate for making the diagnosis. Treatment strategies consist in surgery or endovascular management. Percutaneous endovascular treatment using a stent-graft is a reasonable option for treating arteriovenous fistula. We describe the case of a 50-year-old patient who developed an iliocaval arteriovenous fistula following lumbar disc hernia surgery. The lesion was excluded by a stent-graft. The postoperative period was uneventful. PMID:26920402

    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.

    The uncommon presentation of an arterioportal fistula (APF) involving the superior mesenteric artery (SMA) associated with a pseudoaneurysm represents a therapeutic challenge. We present the case of a 24-year-old female admitted to the hospital after multiple gunshot wounds to the abdomen; the patient underwent multiple surgeries and, in the process, developed a SMA pseudoaneurysm and fistula. The vascular interventional radiology team was consulted for treatment of the pseudoaneurysm and fistula. A covered stent was inserted percutaneously to exclude the APF and the pseudoaneurysm in a single procedure. The patient returned to our service after 21 months for a follow-up CT scan, which demonstrated the stent and the distal vasculature to be patent.

    The authors describe the therapeutic results assembled with perianal fistulae in 130 patients. The best and most reliable method for treatment of the above mentioned lesions is discision or excision of the fistula followed by the so-called "open method" of healing. Since 1988 by this method 74 patients were treated where only two relapses were recorded. Postoperative treatment is simple, dietetic provisions are not necessary. Regular digital control of the wound hastens granulation. After rapid epithelization the wound heals by an almost linear scar. As in particular intersphincteric and low transphincteric fistulae calt for careful sphincterotomy of an appropriate extent it is essential that these operations should be performed by a surgeon adequately experienced in proctosurgery.

A fistula is the preferred access for hemodialysis, and clients must continually monitor and protect their fistula. In this qualitative, ethnographic study, data were collected during fieldwork and semistructured interviews. Constructivism and a cultural negotiation model provided frameworks for the study. Fourteen clients were interviewed; interviews lasted 1.5 to 4 hours. Results revealed new insights into informants'perspectives and experiences with a vascular access. The overarching theme was vulnerability, and underlying themes were body awareness, dependency, mistrust, and stigma. The response to vulnerability was to be continually vigilant and assertive to protect the holistic self Stigma of the vascular access was an important issue for informants and evoked the greatest emotional responses.

    Langerhans cell histiocytosis (LCH) is an uncommon clinically heterogeneous disorder characterized by the proliferation and accumulation of Langerhans cells with local infiltration of tissues and organ destruction. LCH takes many clinical forms, affecting different systems and different sites in the same system with variable outcomes. Bone, skin, lymph node, pituitary, liver, lung, bone marrow and spleen involvement can be seen in patients with LCH. Involvement of the perianal site is rare. In this article, a 16-month-old boy with multiple organ involvement including skin, liver, lung, and bone is presented. Aside from these systemic involvements, he also had a simple anal fistula. According to our best knowledge, this case of LCH with anal fistula is only the second to be reported in childhood. We would like to emphasize that LCH may be associated with anal fistula; therefore, we suggest that patients with LCH should be examined for this condition. PMID:20505285

    We report the case of an 86-year-old man, who had undergone subtotal esophagectomy and reconstruction with a gastric tube through the retrosternal route 7 years ago, who was referred for treatment of a brachiocephalic arteriogastric fistula. An emergency stent-graft placement was performed to prevent massive bleeding from the fistula. After 2 weeks, a follow-up esophagogastroscopy revealed that the gastric tube ulcer had been penetrated, and the stent graft was exposed. Therefore, surgical treatment was indicated. After a carotid-carotid arterial bypass graft was made, the brachiocephalic artery was resected with the stent graft and the gastric wall. The defect between the cervical esophagus and the remnant gastric tube was replaced by a free jejunal graft. The patient tolerated these procedures well and was transferred to the referral hospital 3 months after surgery. Therefore, both an early diagnosis and the administration of multidisciplinary treatment are essential to save patients presenting with an arterioenteric fistula.

    We reported a case in which a nasogastric tube was inserted into the gastrocutaneous fistula, diagnosed by abdominal computed tomography. A 78-year-old man with a history of recurrent cerebral hemorrhage had a percutaneous endoscopic gastrostomy tube due to dysphagia for 2 years. However, soft tissue infection at the gastrostomy site caused the removal of the tube. Immediately, antibiotic agents were infused. For appropriate hydration and medication, a nasogastric tube was inserted. However, there was no significant improvement of the soft tissue infection. Moreover, the amount of bloody exudate increased. Abdominal computed tomography revealed the nasogastric tube placed under the patient's skin via gastrocutaneous fistula. The nasogastric tube was removed, and an antibiotic agents were maintained. After 3 weeks, the signs of infection fully improved, and percutaneous endoscopic gastrostomy was performed again. This case shows necessities of an appropriate interval between removal of the gastrostomy tube and insertion of a nasogastric tube, and suspicion of existence of gastrocutaneous fistula.

    Rectovaginal fistula is a disastrous complication of Crohn's disease (CD) that is exceedingly difficult to treat. It is a disabling condition that negatively impacts a women's quality of life. Successful management is possible only after accurate and complete assessment of the entire gastrointestinal tract has been performed. Current treatment algorithms range from observation to medical management to the need for surgical intervention. A wide variety of success rates have been reported for all management options. The choice of surgical repair methods depends on various fistula and patient characteristics. Before treatment is undertaken, establishing reasonable goals and expectations of therapy is essential for both the patient and surgeon. This article aims to highlight the various surgical techniques and their outcomes for repair of CD associated rectovaginal fistula.

    2011-01-01

    “Why do we have to review our experience in managing idiopathic fistula-in-ano regularly?” In order to answer this apparently simple question, we reviewed our clinical and surgical cases and most important relevant literature to find a rational and scientific answer. It would appear that whatever method you adopt in fistula management, there is a price to pay regarding either rate of recurrence (higher with conservative methods) or impairment of continence (higher with traditional surgery). Since, at the moment, reliable data to identify a treatment as a gold standard in the management of anal fistulas are lacking, the correct approach to this condition must consider all the anatomic and clinicopathological aspects of the disease; this knowledge joined to an eclectic attitude of the surgeon, who should be familiar with different types of treatment, is the only guarantee for a satisfactory treatment. As a conclusion, it is worthwhile to remember that adequate initial treatment significantly reduces recurrence, which, when it occurs, is usually due to failure to recognise the tract and primary opening at the initial operation.

    Cephalic arch stenosis (CAS) is an important and common cause of dysfunction in autogenous haemodialysis fistulas that requires multiple reinterventions and aggressive surveillance. We evaluated the safety and efficacy of the Viabahn stent-graft for the management of CAS. Between April 2005 and October 2011, 11 consecutive patients [four men and seven women (mean age 56.7 years)] with CAS and dysfunctional fistulas were treated with insertion of 11 Viabahn stent-grafts. Six stent-grafts were inserted due to residual stenosis after angioplasty and five for fistuloplasty-induced rupture. No patient was lost to follow-up. The technical and clinical success rate was 100 %. Primary access patency rates were 81.8 % [95 % confidence interval (CI) 0.482-0.977] at 6 months and 72.7 % (95 % CI 0.390-0.939) at 12 months. Secondary access patency rates were 90.9 % at 6 months (95 % CI 0.587-0.997). There were no procedure-related complications. Mean follow-up was 543.8 days (range 156-2,282). The use of the Viabahn stent-graft in the management of CAS is technically feasible and, in this small series, showed patency rates that compare favorably with historical data of angioplasty and bare stents.

    Actinomycosis is a chronic granulomatous infection caused by Actinomyces species which may involve only soft tissue or bone or the two together. Actinomycotic osteomyelitis of maxilla is relatively rare when compared to mandible. These are normal commensals and become pathogens when they gain entry into tissue layers and bone where they establish and maintain an anaerobic environment with extensive sclerosis and fibrosis. This infection spreads contiguously, frequently ignoring tissue planes and surrounding tissues or organ. The portal of entry may be pulpal, periodontal infection, and so forth which may lead to involvement of adjacent structures as pharynx, larynx, tonsils, and paranasal sinuses and has the propensity to damage extensively. Diagnosis is often delayed and is usually based on histopathology as they are cultured in fewer cases. The chronic clinical course without regional lymphadenopathy may be essential in diagnosis. The management of actinomycotic osteomyelitis is surgical debridement of necrotic tissue combined with antibiotics for 3–6 months. The primary actinomycosis arising within the maxilla with contiguous involvement of paranasal sinus with formation of oroantral fistula is rare. Hence, we present a 50-year-old female patient with chronic sclerosing osteomyelitis of maxilla which presented as oroantral fistula with suppurative and sclerotic features. PMID:26451261

    The authors describe the endovascular treatment of a high-output, large-caliber, postnephrectomy aortocaval fistula using a mixture of cyanoacrylate and lipiodol combined with Gianturco coil embolization. Thirty-nine coils were used to decrease the flow through the fistula so that a fast-polymerizing glue mixture could be injected into the fistula. During rapid polymerization, the N-butyl-2-cyanoacrylate (NBCA) mixture was trapped within the coils, providing an easily controllable glue cast in the fistula, thereby preventing inadvertent embolization into the lungs. This approach can be of considerable benefit for the endovascular treatment of central high-output fistulas.

    Proximal enteroatmospheric fistulae are difficult to manage and carry high mortality from sepsis and electrolyte imbalances. Conservative management with total parenteral nutrition, exclusion of fistula, resection and anastomosis are conventional methods of treatment with low success rate. Providing muscle cover to manage an enteroatmospheric fistula is a noble concept. A postoperative high-output gastroatmospheric fistula (GAF) was repaired by superior epigastric artery-based rectus abdominis muscle flap (RAMF). Postoperative recovery was uneventful. This technique may be useful for closure of proximal enteroatmospheric fistulae that fail to heal through medical and conventional surgical management.

    Gastropleural fistula may occur after pulmonary resection, perforated paraesophageal hernia, perforated malignant gastric ulcer at the fundus, or gastric bypass surgery for morbid obesity. We describe a case of gastropleural fistula after stomach perforation by a nasogastric tube in a patient who underwent Billroth II gastric resection for adenocarcinoma. Left biliopneumothorax occurred and was treated by thoracic drainage with -20 cm H2O aspiration. As gastropleural fistula persisted, laparotomy was repeated and gastric and diaphragmatic perforations were sutured. Gastropleural fistula is rare and, to our knowledge, this is the first reported case of gastropleural fistula and biliopneumothorax caused by gastric and diaphragmatic perforation by a nasogastric tube.

    Background: Although traumatic fistula is frequently encountered, high-output heart failure due to fistula is a very rare condition. Despite an indefinitive history of trauma, arteriovenous (AV) fistula may develop insidiously, and therefore identification of a shunt is highly important for treatment. Case Report: Here we report a 46-year-old male patient with heart failure due to traumatic femoral arteriovenous fistula developed following a penetrating stab injury 17 years ago. Conclusion: Traumatic AV fistula is a curable cause of heart failure. Also, careful examination of the patient is as significant as radiological imaging methods. PMID:26185721

    Anal fistula (AF) presents a chronic problem for patients and colorectal surgeons alike. Surgical treatment may result in impairment of continence and long-term risk of recurrence. Treatment options for AFs vary according to their location and complexity. The ideal approach should result in low recurrence rates and minimal impact on continence. New technical approaches involving biologically derived products such as biological mesh, fibrin glue, fistula plug, and stem cells have been applied in the treatment of AF to improve outcomes and decrease recurrence rates and the risk of fecal incontinence. In this review, we will highlight the current evidence and describe our personal experience with these novel approaches. PMID:25435826

    The anterior condylar confluence (ACC) is a small complex venous structure located medial to the jugular vein and adjacent to the hypoglossal canal. To our knowledge, this is the first report of transvenous Onyx embolization for ACC dural arteriovenous fistula (DAVF). Three patients with ACC DAVF were treated using the Onyx liquid embolic agent with or without detachable coils. Complete angiographic obliteration of the fistulas was achieved in all cases without permanent lower cranial neuropathy. This report suggests that the controlled penetration of Onyx is advantageous in order to obliterate ACC DAVFs with a small amount of embolic material.

Therefore, they merit special consideration in both clinical care and research settings. Adoption of a formal bill of rights for patients with fistula similar to the one proposed in the present report should be encouraged at all facilities where these women are treated. Acknowledgment of their rights would help to improve their care and end the abuses they are exposed to in institutional settings.

    Persistent tracheocutaneous fistulae (PTCFs) are sequelae of long-term tracheostomy tube use, and while many procedures exist to correct this issue, several are invasive and incur risk to the patient. This case study discusses a minimally invasive approach to closure of small PFTFs with a coblator device that may reduce the risks associated with other closure procedures. We demonstrated successful tracheocutaneous fistulae closure after coblation in all 4 patients that the operation was performed. We believe this technique can be considered for patients under select circumstances and can be part of a surgeon's armamentarium for the treatment of small PTCFs.

    Aortoenteric fistula (AEF) is an uncommon but serious complication occurring after aortic surgery and may occur at any site in the gastrointestinal tract, with the duodenum being the most common. Conventional surgical repair of secondary AEF has high mortality, whereas endovascular repair has emerged as an alternative treatment despite concerns about persistent or recurrent infection. We report the case of a 91-year old man who was admitted with rectal bleeding from an aorto-appendiceal fistula 9 years after open abdominal aortic aneurysm repair. This rare site for AEF was diagnosed on computed tomography, and we present the first case of endovascular treatment of this uncommon complication.

    We reported a case of a 78-year-old patient with esophagopericardial fistula who was referred for angiographic and interventional management. Emergent implantation of the esophageal stent could not lengthen or even save the patient’s life. One week later, the patient died of multiple organ failure, which was probably from formation of granulation tissue and stent migration. Therefore, if the inflammatory to the esophagopericardial fistula had been better controlled initially, and the implantation of the esophageal stent delayed, our patient would have survived.

    Pancreaticocutaneous fistulas (PCFs) may be refractory to medical therapy or endoscopic retrograde cholangopancreaticography. Four patients underwent endoscopic ultrasound-guided management of refractory PCFs, which were internalized by endoscopic ultrasound-guided transmural puncture of the pancreatic duct (n = 2), fistula tract (n = 1), or both (n = 1), with placement of transmural stents providing internal drainage to the stomach (n = 3) or duodenum (n = 1). Drainage from PCFs ceased in all patients, and all percutaneous drains were removed; internal stents were left in place indefinitely. Endoscopic ultrasound-guided interventions may successfully treat PCFs, allowing removal of percutaneous drains, and are an attractive alternative for patients who might otherwise require pancreatic resection.

Intraoperatively, an abscess that had formed on the aortic annulus and perforated to the right atrium was unexpectedly found, the fistula being occluded by vegetations. Even when no left-to-right shunts are detected by imaging, vegetations adjacent to the atrioventricular septum may conceal a left ventricle-right atrium fistula, resulting in prosthetic valve endocarditis presenting clinically as subaortic stenosis without perivalvular leakage.

    Penetrating injuries in the base of the neck are considered to be the most dangerous due to the potential combination of vascular and intrathoracic lesions. We describe an extremely rare case of combined injury of the trachea and innominate artery, which resulted in formation of a traumatic acute tracheoinnominate fistula. Previously, these fistulas have been described as an iatrogenic complication of tracheostomy, presenting with massive peristomal bleed or hemoptysis. This case demonstrates that a combination of lesions to vital anatomical structures in the neck can change their clinical presentation, making them extremely difficult to diagnose.

    We report a case in which a spontaneous choledochoduodenal fistula occurred after biliary covered self-expanding metal stent (SEMS) placement and a late transfistula migration of the stent in a patient with malignant distal biliary obstruction. A partially covered WallFlex biliary stent (Boston Scientific) was appropriately implanted in the common bile duct. Subsequently the patient received chemotherapy with gemcitabine. After 7 months of the SEMS insertion, the patient presented with frequent vomiting. Abdominal computed tomography revealed the obstruction of the duodenal descending part and the migrated stent in the stomach. A choledochoduodenal fistula was observed endoscopically at the proximal point of the duodenal obstruction. These findings can cleanly account for the SEMS migration through the fistula. The mechanism of formation of the fistula is mostly associated with a mechanical contact between the bile duct wall and the SEMS edge, which is pushed up in the direction of the duodenum because of the enlargement of the primary tumor, finally penetrating through the duodenal wall. To our knowledge, this is an extreme unusual case, which has been unreported previously. Therefore, we emphasize the necessity of being alert to the potential for such complications in cases involving placement of SEMS for malignant biliary obstruction.

    Patient: Female, 81 Final Diagnosis: Gallbladder papillomatosis Symptoms: Epigastric pain Medication: — Clinical Procedure: — Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Biliary papillomatosis (BP) with sole involvement of the gall bladder or gall bladder papillomatosis (GBP) is very rare. Biliary-enteric fistula, particularly the cholecystocolonic fistula (CCF) type, is also very rare. The combination of both types of lesions in a single patient has never previously been reported in the English literature. Case Report: We report herein the case of an 81-year-old woman who was diagnosed with both disease entities, which occurred in a cause-and-effect relationship. She underwent resection of the gall bladder with closure of the fistula, and was discharged improved afterwards. Conclusions: GBP is a premalignant condition that warrants extensive resection. An absent Murphy’s sign or jaundice on physical examination should not rule out this disease or accompanying biliary tract infection because a biliary-enteric fistula may be present. Thorough review of the radiologic images should be performed, since subtle details could be easily missed or dismissed, thus affecting the postoperative course. A CCF should alert the physician that another disease entity is present. PMID:25351203

    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.

    Spontaneous gastrojejunal fistula formation is an extremely rare complication of gastric ulcer disease. We report a 77-year old woman who presented with diffuse abdominal pain, weight loss, malaise, nausea, and occasional dark stools. Laboratory tests showed extreme hyposideremic anemia with inflammatory syndrome. In addition, biochemical parameters of malnourishment were presented. Upper endoscopy revealed the patent esophagus along the full length without any pathological changes. Large and deep ulceration with perforation in the small intestine was detected in the posterior gastric wall. The small intestine loop was reached by endoscope through spontaneously developed gastrojejunal fistula. Polytopic biopsies of described ulcerative change were carried out. Histopathologically reepithelialized ulcerous zone was seen in the gastric mucosa. Also, gastrojejunal fistula was visualized after wide opening of hepatogastric and gastrocolic ligament. Jejunal loop 25 cm from ligament of Treitz was attached to mesocolon and posterior gastric wall because of ulcer penetration. Postoperative course was uneventful. Per oral intake started on the 4(th) postoperative day, and the patient was discharged on the 8(th) postoperative day. In summary, this case indicates that persistent symptoms of peptic ulcer disease associated with nutritional disturbances may be caused by gastrojejunal fistula.

    Cerebrospinal fluid (CSF) fistula as a consequence of brain missile injury and following infectious complications has been recognized for years. Different methods of treatment have been advocated. Missiles used in war cause extensive destruction of the skull and brain as a result of their high kinetic energy. On its transfer through the skull, such high kinetic energy causes fractures called "discontinuous fractures," which are distant from the entry wound and not related to the fracture of the vault. The role of the timely diagnosis of CSF fistulas and their early repair in the management of these wounds is emphasized. Data on 312 patients with missile injuries of the brain inflicted during the war in Croatia were retrieved and analyzed, with special reference to the complications of CSF fistulas and infection. Forty-five patients developed CSF fistula, 15 (33%) of them at the wound site, 23 (51%) as CSF rhinorrhea, and seven (15%) as CSF otorrhea. Six patients developed infectious complications. The presented strategy and operative approach resulted in a low incidence of infectious complications in the study series.

    Perianal fistulization is an inflammatory condition that affects the region around the anal canal, causing significant morbidity and often requiring repeated surgical treatments due to its high tendency to recur. To adopt the best surgical strategy and avoid recurrences, it is necessary to obtain precise radiologic information about the location of the fistulous track and the affected pelvic structures. Until recently, imaging techniques played a limited role in evaluation of perianal fistulas. However, magnetic resonance (MR) imaging now provides more precise information on the anatomy of the anal canal, the anal sphincter complex, and the relationships of the fistula to the pelvic floor structures and the plane of the levator ani muscle. MR imaging allows precise definition of the fistulous track and identification of secondary fistulas or abscesses. It provides accurate information for appropriate surgical treatment, decreasing the incidence of recurrence and allowing side effects such as fecal incontinence to be avoided. Radiologists should be familiar with the anatomic and pathologic findings of perianal fistulas and classify them using the St James's University Hospital MR imaging-based grading system.

    Perianal sepsis is a common condition ranging from acute abscess to chronic fistula formation. In most cases, the source is considered to be a non-specific cryptoglandular infection starting from the intersphincteric space. The key to successful treatment is the eradication of the primary track. As surgery may lead to a disturbance of continence, several sphincter-preserving techniques have been developed. This consensus statement examines the pertinent literature and provides evidence-based recommendations to improve individualized management of patients.

    CONTEXT: Sparse literature exists on laparoscopic repair of urogenital fistulae (UGF). AIMS: The purpose of the following study is to report our experience of laparoscopic UGF repair with emphasis on important steps for a successful laparoscopic repair. SETTINGS AND DESIGN: Data of patients who underwent laparoscopic repair of UGF from 2003 to 2012 was retrospectively reviewed. MATERIALS AND METHODS: Data was reviewed as to the aetiology, prior failed attempts, size, number and location of fistula, mean operative time, blood loss, post-operative storage/voiding symptoms and episodes of urinary tract infections (UTI). RESULTS: Laparoscopic repair of 22 supratrigonal vesicovaginal fistulae (VVF) (five recurrent) and 31 ureterovaginal fistulae (UVF) was performed. VVF followed transabdominal hysterectomy (14), lower segment caesarean section (LSCS) (7) and oophrectomy (1). UVF followed laparoscopy assisted vaginal hysterectomy (18), transvaginal hysterectomy (2) and transabdominal hysterectomy (10) and LSCS (1). Mean VVF size was 14 mm. Mean operative time and blood loss for VVF and UVF were 140 min, 75 ml and 130 min, 60 ml respectively. In 20 VVF repairs tissue was interposed between non-overlapping suture lines. Vesico-psoas hitch was done in 29 patients of urterovaginal fistulae. All patients were continent following surgery. There were no urinary complaints in VVF patients and no UTI in UVF patients over a median follow-up of 3.2 years and 2.8 years respectively. CONCLUSION: Laparoscopic repair of UGF gives easy, quick access to the pelvic cavity. Interposition of tissue during VVF repair and vesico-psoas hitch during UVF repair form important steps to ensure successful repair. PMID:25336817

    It is uncertain whether postoperative pancreatic fistulas after distal and central pancreatectomies behave similarly to those after pancreaticoduodenectomy. To date, this concept has not been validated either clinically or economically. Overall, 256 consecutive pancreatic resections from October 2001 to February 2006 (184 pancreaticoduodenectomies, 66 distal pancreatectomies, and 6 central pancreatectomies) were evaluated according to the International Study Group of Pancreatic Fistula classification scheme. Pancreatic fistula was defined as any measurable drainage on or after postoperative day 3, with amylase content greater than three times the normal serum value. Outcomes were divided into four grades: (1) no fistula, (2) grade A: biochemical fistula without clinical sequelae, (3) grade B: fistula requiring any therapeutic intervention, or (4) grade C: fistula with severe clinical sequelae. Grades B and C are considered clinically relevant fistulas based on worsening morbidity, increased length of stay, frequent hospital readmission, and increased costs/resource utilization. Clinical and economic outcomes were compared-grade for grade-across the three resection types. Fistulas of any extent (Grades A-C) occurred in one third of all patients; two thirds had no fistula. Overall, there were 16 readmissions (6%), six reoperations (2%), and no deaths attributable to pancreatic fistula. Outcomes between no fistula and grade A patients were identical across resection types, though grade A fistula was more common in distal pancreatectomy. For each resection type, length of stay and costs progressively increased with grades B and C. However, the negative impact of these clinically relevant fistulas varied between resection types. Rates for intensive care unit admission and rehabilitation placement were higher among pancreaticoduodenectomy patients. Total parenteral nutrition and antibiotic use were similar, but percutaneous drainage was used more often for distal

    Arteriovenous fistulas (AVF) for hemodialysis access have a 1-year primary patency rate of only 60%, mainly as a result of maturation failure that is caused by insufficient outward remodeling and intimal hyperplasia. The exact pathophysiology remains unknown, but the inflammatory vascular response is thought to play an important role. In the present study we demonstrate that targeted liposomal delivery of prednisolone increases outward remodeling of the AVF in a murine model. Liposomes accumulate in the post-anastomotic area of the venous outflow tract in which the vascular pathology is most prominent in failed AVFs. On a histological level, we observed a reduction of lymphocytes and granulocytes in the vascular wall. In addition, a strong anti-inflammatory effect of liposomal prednisolone on macrophages was demonstrated in vitro. Therefore, treatment with liposomal prednisolone might be a valuable strategy to improve AVF maturation. PMID:27460883

    Objectives Rectovaginal fistulae (RVFs) are often debilitating and there are no established treatment algorithms. We sought to describe current diagnosis and management strategies for RVFs across the United States. Methods This institutional review board–approved multicenter retrospective study included 12 sites. Cases were identified using International Classification of Diseases, Ninth Revision codes during a 5-year period. Demographics, management, and outcomes of RVF treatment were collected. Results Three hundred forty-two charts were identified; 176 (52%) met criteria for inclusion. The mean (SD) age was 45 (17) years. Medical history included hypertension (21%), cancer (17%), Crohn disease (11%), and diabetes (7%). Rectovaginal fistulae were often associated with obstetric trauma (42%), infection/inflammation (24%), and cancer (11%). Overall, most RVFs were primary (94%), small (0.5–1.5 cm; 49%), transsphincteric (31%), and diagnosed via vaginal and rectal (60%) examination. Eighteen percent (32/176) were initially managed conservatively for a median duration of 56 days (interquartile range, 29–168) and 66% (21/32) of these resolved. Almost half (45%) of RVFs treated expectantly were tiny (<0.5 cm). Eighty-two percent (144/176) of subjects were initially managed surgically and 81% (117/144) resolved. Procedures included simple fistulectomy with or without Martius graft (59%), transsphincteric repair (23%), transverse transperineal repair (10%), and open techniques (8%), and 87% of these procedures were performed by urogynecologists. Conclusions In this large retrospective review, most primary RVFs were treated surgically, with a success rate of more than 80%. Two thirds of RVFs managed conservatively resolved spontaneously, and most of these were tiny (<0.5 cm). These success rates can be used in counseling to help our patients make informed decisions about their treatment options. PMID:25730438

    AIM: To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip (OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas. METHODS: From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients (48.8%) presented with severe upper-gastrointestinal (GI) bleeding, 3 (3.6%) patients with lower-GI bleeding, 7 patients (8.3%) underwent perforation closure, 18 patients (21.4%) had prevention of secondary perforation, 12 patients (14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection (ESD) and 3 patients (3.6%) had an intervention on a chronic fistula. RESULTS: In 78/84 patients (92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients (89.28%). The overall mortality in the study patients was 11/84 (13.1%) and was seen in patients with life threatning upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41 (85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 (100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen (2%). CONCLUSION: This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use. PMID:26855543

    Intravenous drug abusers commonly develop endocarditis due to injection of particulate matter that can cause endothelial damage to the valves. The frequent need to access the venous system can result in vascular traumas with potential complications including arteriovenous (AV) fistulas. Here, we present the case of an intravenous drug abuser with endocarditis and an unusually large AV fistula in the groin. The patient was successfully operated for endocarditis. However, the AV fistula was at the time not acknowledged. The combination of ileofemoral vein thrombosis and a large AV fistula led to pulmonary septic embolism and life-threating, right-sided heart failure. Computed tomography scan did not reveal the AV fistula, but suspicion was raised. Ultrasound diagnosed and revealed the magnitude of the AV fistula, and the patient was treated with a minimally invasive percutaneous technique. PMID:26829963

    Heterotopic gastric mucosa patches are congenital gastrointestinal abnormalities and have been reported to occur anywhere along the gastrointestinal tract from mouth to anus. Complications of heterotopic gastric mucosa include dysphagia, upper gastrointestinal bleeding, upper esophageal ring stricture, adenocarcinoma and fistula formation. In this case report we describe the diagnosis and treatment of the first case of esophago-bronchial fistula due to heterotopic gastric mucosa in mid esophagus. A 40-year old former professional soccer player was referred to our department for treatment of an esophago-bronchial fistula. Microscopic examination of the biopsies taken from the esophageal fistula revealed the presence of gastric heterotopic mucosa. We decided to do a non-surgical therapeutic endoscopic procedure. A sclerotherapy catheter was inserted through which 1 mL of ready to use synthetic surgical glue was applied in the fistula and it closed the fistula opening with excellent results. PMID:21160729

    We report a case of vesicocervical fistula following intrauterine device (Lippes loop) erosion following insertion 45 years ago. Vesicocervical fistula was suspected clinically. Ultrasound and magnetic resonance imaging confirmed the presence of a foreign body. Biopsy and magnetic resonance imaging were performed to rule out malignancies of the urogenital tract. The fistula was managed by laparotomy, hysterectomy, and bladder flap closure. We report this case because of its rarity.

    Fistulas, either between oral cavity and external face or between oral and nasal cavity, are major complications after microsurgical head and neck reconstruction. Any flaw in surgical planning, design, and execution may lead to this untoward outcome. Once fistula develops, it may interface with oncologic treatment, endanger the reconstruction, and increase overall patient suffering. This article analyzes individual factors involved in development of fistulas in spite of successful transfer of a free flap and proposes treatment guideline.

    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.

    2013-01-01

    Background Obstetric fistula is a severe condition which has devastating consequences for a woman’s life. The estimation of the burden of fistula at the population level has been impaired by the rarity of diagnosis and the lack of rigorous studies. This study was conducted to determine the prevalence and incidence of fistula in low and middle income countries. Methods Six databases were searched, involving two separate searches: one on fistula specifically and one on broader maternal and reproductive morbidities. Studies including estimates of incidence and prevalence of fistula at the population level were included. We conducted meta-analyses of prevalence of fistula among women of reproductive age and the incidence of fistula among recently pregnant women. Results Nineteen studies were included in this review. The pooled prevalence in population-based studies was 0.29 (95% CI 0.00, 1.07) fistula per 1000 women of reproductive age in all regions. Separated by region we found 1.57 (95% CI 1.16, 2.06) in sub Saharan Africa and South Asia, 1.60 (95% CI 1.16, 2.10) per 1000 women of reproductive age in sub Saharan Africa and 1.20 (95% CI 0.10, 3.54) per 1000 in South Asia. The pooled incidence was 0.09 (95% CI 0.01, 0.25) per 1000 recently pregnant women. Conclusions Our study is the most comprehensive study of the burden of fistula to date. Our findings suggest that the prevalence of fistula is lower than previously reported. The low burden of fistula should not detract from their public health importance, however, given the preventability of the condition, and the devastating consequences of fistula. PMID:24373152

    A 10-y-old ovariohysterectomized ring-tailed lemur (Lemur catta) was presented for exacerbation of respiratory signs. The lemur had a history of multiple examinations for various problems, including traumatic lacerations and recurrent perivulvar dermatitis. Examination revealed abnormal lung sounds and a femoral arteriovenous fistula with a palpable thrill and auscultable bruit in the right inguinal area. A diagnosis of congestive heart failure was made on the basis of exam findings, radiography, abdominal ultrasonography, and echocardiography. The lemur was maintained on furosemide until surgical ligation of the fistula was performed. Postoperative examination confirmed successful closure of the fistula and resolution of the signs of heart failure. Arteriovenous fistulas are abnormal connections between an artery and a vein that bypass the capillary bed. Large arteriovenous fistulas may result in decreased peripheral resistance and an increase in cardiac output with consequent cardiomegaly and high output heart failure. This lemur's high-flow arteriovenous fistula with secondary heart failure may have been iatrogenically induced during blood collection by prior femoral venipuncture. To our knowledge, this report is the first description of an arteriovenous fistula in a prosimian. Successful surgical correction of suspected iatrogenic femoral arteriovenous fistulas in a cynomolgus monkey (Macaca fascicularis) and a rhesus macaque (Macaca mulatta) have been reported previously. Arteriovenous fistula formation should be considered as a rare potential complication of venipuncture and as a treatable cause of congestive heart failure in lemurs.

    Background Obstetric fistula is a childbirth injury prevalent in sub-Saharan Africa that causes uncontrollable leaking of urine and/or feces. Research has documented the social and psychological sequelae of obstetric fistula, including mental health dysfunction and social isolation. Purpose This cross-sectional study sought to quantify the psychological symptoms and social support in obstetric fistula patients, compared with a patient population of women without obstetric fistula. Methods Participants were gynecology patients (N = 144) at the Kilimanjaro Christian Medical Center in Moshi, Tanzania, recruited from the Fistula Ward (n = 54) as well as gynecology outpatient clinics (n = 90). Measures included previously validated psychometric questionnaires, administered orally by Tanzanian nurses. Outcome variables were compared between obstetric fistula patients and gynecology outpatients, controlling for background demographic variables and multiple comparisons. Results Compared to gynecology outpatients, obstetric fistula patients reported significantly higher symptoms of depression, posttraumatic stress disorder, somatic complaints, and maladaptive coping. They also reported significantly lower social support. Conclusions Obstetric fistula patients present for repair surgery with more severe psychological distress than gynecology outpatients. In order to address these mental health concerns, clinicians should engage obstetric fistula patients with targeted mental health interventions. PMID:25670025

    Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-old woman with a fistula between the right upper bronchus and bronchus intermedius. A diagnosis of inter-bronchial fistula caused by endobronchial tuberculosis was based on the results of chest computed tomography scans, bronchoscopy, and microbiological and pathological tests. The patient was treated with anti-tuberculous medication, and her symptoms gradually improved.

    The authors report an extremely rare case of spinal intraosseous epidural arteriovenous fistula (AVF) with perimedullary vein reflux causing symptoms of myelopathy. The intraosseous fistula tracts were completely obliterated with Onyx embolic agent, resulting in a total resolution of symptoms. The unique features of this case include the rare location of the fistula in the vertebral body and the association of the fistula with a compressive fracture. Imaging studies confirmed these hemodynamic findings and provided clarity and direct evidence regarding the association of epidural AVF formation with the vertebral compressive fracture. The authors also propose a possible disease evolution based on the previously adduced reflux-impending mechanism.

    Laminar shear stress (SS) induces an antiproliferative and anti-inflammatory endothelial phenotype and increases Klf2 expression. We altered the diameter of an arteriovenous fistula (AVF) in the mouse model to determine whether increased fistula diameter produces disturbed SS in vivo and if acutely increased disturbed SS results in decreased Klf2 expression. The mouse aortocaval fistula model was performed with 22, 25, or 28 gauge needles to puncture the aorta and the inferior vena cava. Duplex ultrasound was used to examine the AVF and its arterial inflow and venous outflow, and SS was calculated. Arterial samples were examined with western blot, immunohistochemistry, and immunofluorescence analysis for proteins and qPCR for RNA. Mice with larger diameter fistulae had diminished survival but increased AVF patency. Increased SS magnitudes and range of frequencies were directly proportional to the needle diameter in the arterial limb proximal to the fistula but not in the venous limb distal to the fistula, with 22-gauge needles producing the most disturbed SS in vivo. Klf2 mRNA and protein expression was diminished in the artery proximal to the fistula in proportion to increasing SS. Increased fistula diameter produces increased SS magnitude and frequency, consistent with disturbed SS in vivo. Disturbed SS is associated with decreased mRNA and protein expression of Klf2. Disturbed SS and reduced Klf2 expression near the fistula are potential therapeutic targets to improve AVF maturation. PMID:25780089

    Superior mesenteric arteriovenous fistula is a rare vascular disorder. Endovascular embolization has been widely used to treat this disease. Patients receiving successful fistula embolization generally have good prognoses. We present a man with iatrogenic superior mesenteric arteriovenous fistula who received endovascular embolization. Portal thrombus was detected on postoperative day 2, and the patient eventually died of multiple organ failure on postoperative day 13 despite having received antithrombotic and antiplatelet therapy. We identified portal thrombosis as a serious complication of transcatheter superior mesenteric arteriovenous fistula embolization.

    Congenital anterior urethrocutaneous fistula and megalourethra are both rare anomalies. These anomalies are commonly associated with other anorectal or genitourinary anomalies and evaluated with voiding cystourethrography. We examined a 34-month-old boy who presented with a fistula at the penoscrotal junction. A voiding cystourethrogram showed a jet of urine coming through the fistula and proximal saccular dilatation of the penile urethra. We present the imaging findings of the first case of an association between a congenital anterior urethrocutaneous fistula at the penoscrotal junction and a proximal penile megalourethra. We also discuss the etiology, management, and differential diagnosis of this entity, and review the literature. PMID:27200160

    A case of bilateral coronary artery fistula into main pulmonary artery which courses with crisis of angina and subepicardial ischaemic changes in anterolateral leads is presented. The interest of the case reported is based on the peculiar anatomy of the fistula; there is only an unique collector to the pulmonary artery for both fistula and they present a completely different way of emerging: an unique vessel from the right coronary artery and several vessels from the anterior descending coronary artery. Ligation of the fistula was performed successfully and postoperative course was uneventful.

    A 22-year-old female patient was treated for spino-renal fistula as a result of a high-velocity gunshot injury to her abdomen. The patient presented with meningeal signs, a headache and right monoparesis. A CT scan of her abdomen revealed a leak of contrast from the right kidney into the perirenal space and tracking further into the thecal sac. An MRI scan showed a stable fracture of L3 with slight compression of the thecal sac and features of cord contusion caused by the shockwave of the bullet. To the best of our knowledge a spino-renal fistula of traumatic origin has not previously been reported in the English language literature.

    Congenital deformities of the labyrinth of the inner ear can be associated with a fistulous communication between the intracranial subarachnoid space and the middle ear cavity. We describe seven such cases, six confirmed by high resolution CT and one by postmortem histological section. The seven patients all presented with meningitis although a cerebrospinal fluid fistula was demonstrated at subsequent surgery or postmortem. The lesions were bilateral in three patients, unilateral in three and probably bilateral in the postmortem case although only one temporal bone was obtained. In every case there was a dilated sac instead of the normal two and a half turn cochlea on the affected side and this was confirmed at surgery. The demonstration of the basal cochlear turn is of paramount importance in any deaf child presenting with meningitis. A true Mondini deformity with a normal basal turn and some hearing is not at risk of developing a fistula. PMID:8345296

    Peroneal artery arteriovenous fistulas and pseudoaneurysms are extremely rare with the majority of reported cases due to penetrating, orthopedic, or iatrogenic trauma. Failure to diagnose this unusual vascular pathology may lead to massive hemorrhage or limb threatening ischemia. We report an interesting case of a 14-year-old male who presented with acute musculoskeletal pain of his lower extremity. Initial radiographs were negative. Further imaging workup revealed a peroneal arteriovenous fistula with a large pseudoaneurysm. After initial endovascular intervention was unsuccessful, the vessels were surgically ligated in the operating room. Pathology revealed papillary endothelial hyperplasia consistent with an aneurysm and later genetic testing was consistent with Ehlers-Danlos syndrome Type IV. This case illustrates an unusual cause of acute atraumatic musculoskeletal pain and uncommon presentation of Ehlers-Danlos syndrome. PMID:25349770

    In the October 2005 Earthquake in mountainous Azad Kashmir and adjacent areas in Pakistan, a young female sustained crush injury chest and upper abdomen. She remained hospitalized with lower chest pain. All initial investigations were normal and she was discharged symptom-free on conservative management. Six months later, she developed acute left sided chest pain and dyspnoea. Provisional diagnosis of empyema was made on X-ray, and tube thoracostomy was done. Diagnostic VATS revealed gastropleural fistula secondary to necrosis of herniated stomach. Resection of necrosed stomach, repair of diaphragm and decortication and transthoracic repair with lower thoracoplasty two months later was performed but both were unsuccessful. After another 02 months, a Roux-en-Y gastrojejunostomy at fistula site was fashioned which proved curative.

    Abstract Background: To report the first case of the spontaneous appendicovesical fistulas' (AVF) repair with robot assisted laparoscopy. Case Presentation: A 29-year-old male patient with urgent persistant bacteriuria and dysuria was referred to our clinic. Physical examination and blood tests were normal. He had used various antibiotics due to recurrent UTI for about 20 years. Computed tomography revealed the fistula tract between the distal end of the appendix and right lateral wall of the bladder dome. He was successfully treated with robot-assisted laparoscopic repair. Following this surgery, the patient's complaints were resolved completely. Conclusion: AVF is the rare condition. Robot-assisted laparoscopy repair of AVF is safe and effective treatment option.

    Obstetric fistulas continue to be a problem in low- and middle-income nations, affecting women of childbearing age during pregnancy and labor and resulting in debilitating urinary and/or fecal incontinence. Historically, this predicament also affected women in high-income nations until the middle of the last century. This is not a "new world" crisis therefore, but simply one of economic and health development. In the last two decades, new global initiatives have been instituted to improve training and education in preventative and curative fistula treatment by developing a unified and competency-based learning tool by surgeons in the field in partnership with FIGO and its global partners. This modern approach to the management of a devastating condition can only serve to achieve the WHO objective of health security for women throughout their life span.

    Reverse total shoulder arthroplasty is becoming a common form of shoulder arthroplasty that is often performed in the setting of rotator cuff pathology. Infection is a rare complication but is more common in reverse total shoulder arthroplasty than in hemiarthroplasty or anatomic total shoulder arthroplasty. We present the case of a 69-year-old patient with a reverse total shoulder arthroplasty who presented with purulent drainage from the skin of his anterior shoulder. Computed tomography arthrogram confirmed the presence of a synovial cutaneous fistula. Synovial cutaneous fistula is a rare variant of periprosthetic infection that, to our knowledge, has not been described previously in the setting of a reverse total shoulder arthroplasty. Computed tomography arthrogram proved to be a reliable method for confirming the diagnosis and was used for operative planning to remove the hardware. PMID:27257460

    Vesicovaginal fistula (VVF) is a condition associated with a number of physical and psychological consequences. In order to gain a deeper understanding of the issues faced by women diagnosed with VVF, a qualitative exploratory study was carried out to explore the experiences of women suffering from VVF. The study included 8 women hospitalized with the diagnosis of vesicovaginal fistula at Kohi Goth Women's Hospital, Karachi, Pakistan. Semi structured interviews of each participant were conducted, recorded, and transcribed. Five major themes were identified, among which all of the participants experienced physical discomforts, psychological disturbances, issues with social and interpersonal relationships and financial constraints. However, concerns with religious practices were experienced by 87.5% of the participants. Pakistani women who are suffering through VVF face many challenges. Combined efforts should be made to offer supportive services to women suffering from this condition. PMID:24169399

    Bronchobiliary fistula (BBF) is a rare condition in which an abnormal communication exists between the bile ducts and the bronchial tree. Malignancy is the most common etiology of BBF, although many others are possible. A 74-year-old male patient with an inoperable Klatskin tumor presented with a complaint of yellow-green sputum and cough; the patient underwent fiber-optic bronchoscopy based on a preliminary diagnosis of bronchobiliary fistula. Using fiber-optic rigid bronchoscopy, the laterobasal segment of the lower right lung lobe was occluded using three pieces of 5-mm Endobronchial Watanabe Spigot. Bile drainage subsequently ceased. A bronchoscopic approach provides an alternative option for BBF treatment, particularly in patients who choose not to undergo surgery, or for whom surgery is not an option due to their underlying general condition.

    The occurrence of multiple spinal dural arteriovenous fistulas (AVFs) is rare. The majority of cases reported are synchronous and the lesions are mainly found at different spinal levels. Metachronous AVFs have been defined as lesions that manifest in a temporal sequence after treatment of a first AVF. In this report, we present two distinct cases of multiple spinal AVFs. Also, we review the main features of the cases previously reported, with emphasis on the proposed theories for the origin of multiple AVFs. In patients with failure to improve after treatment of a spinal DAVF, a whole-spine angiographic examination is mandatory, not only to ascertain the complete closure of the treated fistula, but also to look for a possible second lesion at a different spinal level.

    A captive adult male grizzly bear (Ursus arctos horribilis) was evaluated due to multifocal wounds of the skin and subcutaneous tissues sustained as a result of trauma from another grizzly bear. On presentation, one lesion that was located in the perineal region seemed to be a deep puncture with purple tissue protruding from it. This perineal wound did not heal in the same manner or rate as did the other wounds. Twenty-five days after initial detection, substantial active hemorrhage from the lesion occurred and necessitated anesthesia for examination of the bear. The entire lesion was surgically excised, which later proved curative. An acquired arteriovenous fistula was diagnosed via histopathology. Arteriovenous fistulas can develop after traumatic injury and should be considered as a potential complication in bears with nonhealing wounds.

    A 28-year-old woman was referred to our institution with hope for another child after having an abortion several months previously to avoid a potential risk of catastrophic hemorrhage from a retroperitoneal arteriovenous fistula (AVF) with enlarged and twisted draining veins in the pelvis. Multiple branches coming from the right lumbar arteries and the right iliac arteries fed fistulae converging on an enlarged venous pouch anterior to the psoas major muscle in the right retroperitoneal space. It seemed impossible to achieve complete occlusion of the lesion in a single session by either transarterial or transvenous approach. A laparotomy and direct puncture of the enlarged draining vein immediately downstream of the venous pouch was performed and embolization was done with n-butyl cyanoacrylate and the aid of coils. Complete occlusion of the retroperitoneal AVF was achieved and confirmed in control angiography 5 months later.

    Ureteroarterial fistulas (UAFs) are defined as an abnormal communication between one of the major arteries and the ureter. Urologists most frequently encounter iatrogenic fistulas occurring in patients with a history of pelvic extirpative surgery, chronic ureteral catheterization, and history of pelvic radiation. We present two cases of UAFs in patients with no history of prior radiation, who underwent open radical cystectomy and robot-assisted radical cystectomy with intracorporeal ileal conduit. Both patients developed postoperative ureteroileal anastomotic leaks that were managed with indwelling ureteral catheters. Furthermore, both patients were having left-sided UAF after presenting with nonlife threatening gross hematuria, which became brisk and pulsatile during ureteral stent exchange. Endovascular stenting was performed in both patients with resolution of hemorrhage and full recovery. In one patient, nephrostomy tubes were placed and ureteral catheters were removed; the second patient was managed with continued ureteral catheterization without further episodes of hematuria.

    Summary A 34-year-old woman presented with a history of persisting headache for years, and a newly developed dizziness, left facial palsy and right hemiparesis two days prior to this admission. Initial computed tomographic angiography of the head demonstrated an area of increased density in the left middle and posterior fossae. Multiple aneurysmally dilated venous ectasias with contrast enhancement at the left pre-pontine cistern causing a massive mass effect to the brainstem were also noted, suggesting a huge vascular abnormality. Digital subtraction angiography revealed an abnormal vascular lesion surrounding the brainstem, which indicated a left direct carotid-cavernous fistula with posterior drainage. As her consciousness deteriorated the next day, a follow-up computed tomography scan was done which revealed a pontine hemorrhage. Subsequently, endovascular closure of the fistula with sacrifice of the left ICA was performed, which successfully eliminated the imaging abnormalities. PMID:25207913

    We report the case of a 25-year-old woman who developed a tracheocarotid fistula secondary to an infected endovascular stent placed in the right carotid artery after the patient experienced hemorrhage on her first tracheostomy change. The patient originally had the tracheostomy placed at an outside hospital in September 2014, due to prolonged intubation after a motor vehicle accident. The patient presented to the otolaryngology service with an acute tracheal hemorrhage. This necessitated a neck exploration, median sternotomy, right carotid stent removal with subclavian to carotid bypass, and sternocleidomastoid flap reconstruction. This paper addresses the epidemiology and anatomy of a tracheocarotid fistula and discusses methods to treat such a complication. PMID:26693370

    Sarcoidosis is a common multisystem granulomatous condition of unknown aetiology, predominantly involving the respiratory system. Tracheal stenosis has been described but we believe that we present the first case of a tracheo-oesophageal fistula secondary to chronic sarcoidosis. A 57-year-old woman with sarcoidosis, a known tracheal stricture and a Polyflex(®) stent in situ presented with stridor. Bronchoscopy confirmed in-stent stenosis, by exuberant granulation tissue. The stent was removed and the granulation tissue was resected accordingly. Postoperatively, the patient was noticed to have an incessant cough and video fluoroscopy raised the suspicion of a tracheo-oesophageal fistula. A repeat bronchoscopy demonstrated marked granulation tissue, accompanied by a fistulous connection with the oesophagus at the mid-lower [middle of the lower] third of the trachea. Three Polyflex(®) stents were sited across the entire length of the trachea. Sarcoidosis presents with varying clinical manifestations and disease progression. Tracheal involvement appears to be a rare phenomenon and usually results in stenosis. To date, there has been little or no documented literature describing the formation of a tracheo-oesophageal fistula resulting from sarcoidosis. Early reports documented the presence of sarcoidosis induced weakening in the tracheal wall, a process termed tracheal dystonia. Weaknesses are more apparent in the membranous aspect of the trachea. Despite the rare nature of such pathology, this case report highlights the need to consider the presence of a tracheo-oesophageal fistula in sarcoidosis patients presenting with repeat aspiration in the absence of an alternate pathology.

    Objective Treatment of intracranial dural arteriovenous fistulas (dAVFs) remains a challenge. However, after introduction of Onyx, transarterial approach is the preferred treatment option in many centers. We report our experience of dAVFs embolization with special emphasis on transarterial approach. Methods Seventeen embolization procedures were performed in 13 patients with dAVFs between Jan 2009 and Oct 2014. Clinical symptoms, location and type of fistulas, embolization methods, complications, radiological and clinical outcomes were evaluated using charts and PACS images. Results All 13 patients had symptomatic lesions. The locations of fistulas were transverse-sigmoid sinus in 6, middle fossa dura in 4, cavernous sinus in 2, and superior sagittal sinus in 1 patient. Cognard types were as follows : I in 4, IIa in 2, IIa+IIb in 5, and IV in 2. Embolization procedures were performed ≥2 times in 3 patients. Nine patients were treated with transarterial Onyx embolization alone. One of these required direct surgical puncture of middle meningeal artery. Complete obliteration of fistulas was achieved in 11/13 (85%) patients. There were no complications except for 1 case of Onyx migration in cavernous dAVF. Modified Rankin scale score at post-operative 3 months were 0 in 11, and 3 in 2 patients. Conclusion Transarterial Onyx embolization can be a first line therapeutic option in patients with dAVFs. However, transvenous approach should be tried first in cavernous sinus dAVF because of the risk of intracranial migration of liquid embolic materials. Furthermore, combined surgical endovascular approach can be considered as a useful option in inaccessible route. PMID:26885282

    Context: Chronic pancreatitis is an inflammatory condition that may result in progressive parenchymal damage and fibrosis which can ultimately lead to destruction of pancreatic tissue. Fistulas to the pleura, peritoneum, pericardium, and peripancreatic organs may form as a complications of pancreatitis. This case report describes an exceedingly rare complication, pancreaticoureteral fistula (PUF). Only two additional cases of PUF have been reported. However, they evolved following traumatic injury to the ureter or pancreatic duct. No published reports describe PUF as a complication of pancreatitis. Case Report: A 69-year-old Hispanic female with a past medical history of cholecystectomy, pancreatic pseudocyst, and recurrent episodes of pancreatitis presented with severe, sharp, and constant abdominal pain. Upon imaging, a fistulous tract was visualized between the left renal pelvis (at the level of an upper pole calyx) and the pancreatic duct and a ureteral stent was placed to facilitate fistula closure. Following the procedure, the patient attained symptomatic relief and oral intake was resumed. A left retrograde pyelogram was repeated 2 months after the initial stent placement and demonstrating no evidence of a persistent fistulous tract. Conclusion: Due to PUF's unclear etiology and possible variance of presentation, it is important for physicians to keep this rare complication of pancreatitis in mind, especially, when evaluating a patient with recurrent pancreatitis, urinary symptoms and abnormal imaging within the urinary collecting system and pancreas.

  6. Endoscopic therapies for leaks and fistulas after bariatric surgery.

    2014-02-01

    Bariatric surgery is the most effective treatment for the medical comorbidities associated with morbid obesity. Though uncommon, staple line or anastomotic leaks after bariatric surgery are highly morbid events and challenging to treat. In selected patients without severe sepsis or distant pollution, endoscopic transluminal peritoneal drainage may provide source control. For leaks within 3 days of surgery, endoscopic stenting does not appear to speed closure but does permit oral nutrition. In uncomplicated situations, the risk of migration and resulting complications of enteric stents appear to overshadow the benefits. Initial treatment failures and leaks presenting more than 48 hours after surgery respond to enteric diversion by endoscopic stenting. Occlusion of the leak by injection of fibrin glue also shows promise; however, these case series are limited to a small number of patients. Endoclips may work best to occlude leaks and close fistulas if the epithelium is debrided. As suturing technology improves, direct internal closure of fistulas may prove feasible. Therapeutic endoscopy offers several technologies that can assist in the closure of early leaks and that are essential to the treatment of late leaks and fistulas after bariatric surgery.

    Delonix regia and Cassia fistula seed extracts were evaluated for their antioxidant activity, total phenolics, ash, zinc and fatty acid content. Fourier Transform Infrared Spectroscopy (FTIR) was utilized to assess the chemical functionalities present within the seeds. Antioxidant activity was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Trolox equivalent antioxidant capacity (TEAC) assays. Total phenolics were determined by the Folin-Ciocalteu assay. Lipid extracts were characterized by nuclear magnetic resonance spectroscopy and gas chromatography/mass spectrometry. Zinc concentration was determined by atomic absorption spectroscopy. Extracts from the seeds of C. fistula had a higher antioxidant activity, free radical scavenging activity, and phenolic content than D. regia. FTIR revealed that the seeds are a rich source of protein with small quantities of fat. C. fistula extracts contained a higher percentage of total fat than D. regia. Palmitic acid was identified as the predominant saturated fatty acid in both extracts. Oleic acid and linoleic acid were identified in smaller quantities. Seed extracts may be considered for use in food and nutraceutical applications. PMID:27034834

    A 64-year-old woman with a history of a Stamey procedure for stress incontinence 20 years previously, underwent a diagnostic flexible cystoscopy to investigate recurrent urinary sepsis. Cystoscopic examination demonstrated a large vesicular calculus. When traction was applied to the calculus it was shown to be attached to a 10 cm length of non-absorbable suture material. The suture was attached to two further calculi, apparently originating from outside the bladder wall. All visible calculi and the suture were removed. In the following weeks the patient reported passage of air and faeculent material per-urethra. A repeat cystoscopy revealed an opening in the posterolateral bladder wall and CT confirmed the presence of an enterovesical fistula. Laparoscopy demonstrated a fistula between the terminal ileum and bladder wall. A further 10 cm length of non-absorbable suture material was removed from the terminal ileum and omentum. Laparoscopic repair of the fistula was performed successfully and the patient has remained symptom free following the procedure. PMID:25239995

Antioxidant activity was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and Trolox equivalent antioxidant capacity (TEAC) assays. Total phenolics were determined by the Folin-Ciocalteu assay. Lipid extracts were characterized by nuclear magnetic resonance spectroscopy and gas chromatography/mass spectrometry. Zinc concentration was determined by atomic absorption spectroscopy. Extracts from the seeds of C. fistula had a higher antioxidant activity, free radical scavenging activity, and phenolic content than D. regia. FTIR revealed that the seeds are a rich source of protein with small quantities of fat. C. fistula extracts contained a higher percentage of total fat than D. regia. Palmitic acid was identified as the predominant saturated fatty acid in both extracts. Oleic acid and linoleic acid were identified in smaller quantities. Seed extracts may be considered for use in food and nutraceutical applications. PMID:27034834

    Chronic expanding hematoma of the thorax is not typically accompanied by a bronchopleural fistula or purulent lesion. We report an extremely rare case of chronic expanding hematoma with a bronchopleural fistula and empyema space in a 66-year-old man with a history of tuberculous pleurisy admitted because of fever and bloody sputa. Computed tomography and a magnetic resonance imaging revealed a huge mass and an air space in the right thorax. A fiber-optic bronchoscope examination showed hemorrhagic effusion from the apical bronchus of the right lower lobe. First, open-window thoracostomy was undertaken to control the septic state and to prevent aspiration of infected pleural fluid. At operation, air leakage was found at the most superior portion in the rear of the thoracic empyema space; this was thought to be from the bronchopleural fistula. Enterococcus casseliflavus was detected in cultures for bacteria of the effusion from the empyema space. After an improvement of his general condition, a radical operation, including the complete extirpation of the hematoma and intrathoracic muscle transposition using the latissimus dorsi muscle, was successfully performed.

    Gastrointestinal perforations, leaks and fistulas may be serious and life-threatening. The increasing number of endoscopic procedures with a high risk of perforation and the increasing incidence of leakage associated with bariatric operations call for a minimally invasive treatment for these complications. The therapeutic approach can vary greatly depending on the size, location, and timing of gastrointestinal wall defect recognition. Some asymptomatic patients can be treated conservatively, while patients with septic symptoms or cardio-pulmonary insufficiency may require intensive care and urgent surgical treatment. However, most gastrointestinal wall defects can be satisfactorily treated by endoscopy. Although the initial endoscopic closure rates of chronic fistulas is very high, the long-term results of these treatments remain a clinical problem. The efficacy of endoscopic therapy depends on several factors and the best mode of treatment will depend on a precise localization of the site, the extent of the leak and the endoscopic appearance of the lesion. Many endoscopic tools for effective closure of gastrointestinal wall defects are currently available. In this review, we summarized the basic principles of the management of acute iatrogenic perforations, as well as of postoperative leaks and chronic fistulas of the gastrointestinal tract. We also described the effectiveness of various endoscopic methods based on current research and our experience. PMID:26457014

    Evaluation of the characteristics of urogenital fistula with a retrospective study at the clinic of Urology Ginecologica in the Instituto Nacional de Perinatologia between March 1992 to June 1995, information of the location, etiopathogenesis of the disease, urinary tract infection and surgical treatment were obtained form de patients records in the clinic. The etiophatogenesis of the disease was surgical gynecological procedures in 51.1%, and obstetric cause 48.5%; the location were 14 (66.6%) vesicovaginal, 5 (23.5% 0 ureterovaginal and 2 (urethrovaginal). The abdominal approach were in 8 patients and vaginal route in 9, no surgical treatment were 2. Successfully repair fistula were in 80.9%. Urinary tract infections before treatment agreed on the obstetric etiology was 47.6%, and for surgical gynecological procedures 52.2%. There is an increase in the incident of obstetric vesicovaginal fistula, we believe it depends on the patients that we have in de Instituto Nacional de Perinatologia, most of them are obstetric patients.

    Background A vesicovaginal fistula (VVF) is an abnormal fistulous tract between the bladder and vagina, causing continuous loss of urine via the vagina. VVF is a relatively uncommon condition, but there is a drastically higher prevalence in the developing world. Furthermore, iatrogenic postoperative VVF is most common in developed countries, compared to mainly obstetric trauma in developing countries. In this review we focus on the development of current management techniques for VVF. Methods Medline was searched to identify articles related to urogenital fistulae, including VVF. Based on these reports we focus on the aetiology, clinical presentation, diagnosis and management of VVF. This in-depth review includes the optimal surgical timing, different surgical approaches (including minimally invasive techniques such as laparoscopic and robotic surgery), recommendations for postoperative care, surgical complications, and the need for further research in the use of robotic surgery to treat this condition. Results In all, 60 articles were identified and included in this review; eight were related to the aetiology, 12 to diagnosis, and 40 to the management of VVF. A thorough evaluation of VVF is imperative for planning the repair. Although the surgeonís experience typically influences the surgical approach, special situations will dictate the best approach. Conclusion The treatment of genitourinary fistulae with robotic assistance continues to develop, but further research is necessary to fully understand the use of this technology. PMID:26019933

    A prospective trial was performed comparing the accuracy of digital examination and anal endosonography in defining the anatomy of anal fistulae. Before operation 38 consecutive patients were assessed by the consultant in charge of the case, by a research fellow and by anal endosonography involving two radiologists. These findings were compared with the operative findings. Consultants correctly identified 26 of 33 internal openings, 29 of 34 primary tracks and 15 of 21 secondary tracks. The research fellow correctly identified 26 internal openings, 24 primary tracks and 10 secondary tracks. There was no significant difference between the accuracy of consultants and the research fellow. Anal endosonography identified 10 internal openings based on initial criteria. This rose to 24 when revised ultrasonographic criteria were applied. There was no statistical difference between consultant assessment and anal ultrasonography in correctly identifying intersphincteric and transphincteric tracks. Ultrasonography is unable to assess primary superficial, suprasphincteric and extrasphincteric tracks or secondary supralevator and infralevator tracks. Consultant assessment of secondary supralevator and infralevator tracks was correct in 78 per cent of cases. PMID:2032103

    Aortic arch calcification (AAC) is recognized as an important cardiovascular risk factor in patients with end-stage renal disease (ESRD). The aim of the study was to evaluate the impact of AAC grade on patency rates of arteriovenous fistula (AVF) in this specific population. The data of 286 ESRD patients who had an initial AVF placed were reviewed. The extent of AAC identified on chest radiography was divided into four grades (0–3). The association between AAC grade, other clinical factors, and primary patency of AVF was then analyzed by Cox proportional hazard analysis. The multivariate analysis demonstrated that the presence of AAC grade 2 (hazard ratio (95% confidence interval): 1.80 (1.15–2.84); p = 0.011) and grade 3 (3.03 (1.88–4.91); p < 0.001), and higher level of intact-parathyroid hormone (p = 0.047) were associated with primary patency loss of AVF. In subgroup analysis, which included AVF created by a surgeon assisted with preoperative vascular mapping, only AAC grade 3 (2.41 (1.45–4.00); p = 0.001), and higher intact-parathyroid hormone (p = 0.025) level were correlated with AVF patency loss. In conclusion, higher AAC grade and intact-parathyroid hormone level predicted primary patency loss of AVF in an ESRD population. PMID:27101807

  16. Obstetric Fistula in Burundi: a comprehensive approach to managing women with this neglected disease

    2013-01-01

    Background In Burundi, the annual incidence of obstetric fistula is estimated to be 0.2-0.5% of all deliveries, with 1000–2000 new cases per year. Despite this relatively high incidence, national capacity for identifying and managing obstetric fistula is very limited. Thus, in July 2010, Medecins Sans Frontieres (MSF) set up a specialised Obstetric Fistula Centre in Gitega (Gitega Fistula Centre, GFC), the only permanent referral centre for obstetric fistula in Burundi. A comprehensive model of care is offered including psychosocial support, conservative and surgical management, post-operative care and follow-up. We describe this model of care, patient outcomes and the operational challenges. Methods Descriptive study using routine programme data. Results Between July 2010 and December 2011, 470 women with obstetric fistula presented for the first time at GFC, of whom 458 (98%) received treatment. Early urinary catheterization (conservative management) was successful in four out of 35 (11%) women. Of 454 (99%) women requiring surgical management, 394 (87%) were discharged with a closed fistula, of whom 301 (76%) were continent of urine and/or faeces, while 93 (24%) remained incontinent of urine and/or faeces. In 59 (13%) cases, the fistula was complex and could not be closed. Outcome status was unknown for one woman. Median duration of stay at GFC was 39 days (Interquartile range IQR, 31–51 days). The main operational challenges included: i) early case finding and recruitment for conservative management, ii) national capacity building in obstetric fistula surgical repair, and iii) assessing the psychosocial impact of this model. Conclusion In a rural African setting, it is feasible to implement a comprehensive package of fistula care using a dedicated fistula facility, and satisfactory surgical repair outcomes can be achieved. Several operational challenges are discussed. PMID:23965150

    Patient: Male, 32 Final Diagnosis: Thoracic duct chylous fistula Symptoms: Fistula Medication: — Clinical Procedure: A boneless muscle flap transplantatio Specialty: — Objective: Rare disease Background: As patients with thoracic duct injuries often suffer from severe local soft tissue defects, integrated surgical treatment is needed to achieve damage repair and wound closure. However, thoracic duct chylous fistula is rare in burn patients, although it typically involves severe soft tissue damage in the neck or chest. Case Report: A 32-year-old male patient fell after accidentally contacting an electric current (380 V) and knocked over a barrel of sulfuric acid. The sulfuric acid continuously poured onto his left neck and chest, causing combined electrical and sulfuric acid burn injuries to his anterior and posterior torso, and various parts of his limbs (25% of his total body surface area). During treatment, chylous fistula developed in the left clavicular region, which we diagnosed as thoracic duct chylous fistula. We used diet control, intravenous nutritional support, and continuous somatostatin to reduce the chylous fistula output, and hydrophilic silver ion-containing dressings for wound coverage. A boneless muscle flap was used to seal the left clavicular cavity, and, integrated, these led to resolution of the chylous fistula. Conclusions: Patients with severe electric or chemical burns in the neck or chest may be complicated with thoracic duct injuries. Although conservative treatment can control chylous fistula, wound cavity filling using a muscle flap is an effective approach for wound healing. PMID:27725628

    Although hemodialysis catheters predispose to infection which, in turn, causes inflammation, we studied whether they induce inflammation independent of infection. We compared the level of the inflammatory marker C-reactive protein (CRP) in maintenance hemodialysis patients, comparing those dialyzed using a non-infected catheter to those using arteriovenous fistulas. All incident patients had catheters and fistula placement at dialysis initiation. In 35 patients the fistulas matured, the catheters were removed and the patients were evaluated at 6 months (catheter-fistula). These results were compared to 15 patients in whom the fistula did not mature and catheter use persisted for 6 months (catheter-catheter). There was a significant 82% reduction in the CRP level in the catheter-fistula group but a 16% increase in the catheter-catheter group at 6 months. The changes in CRP did not differ by gender, diabetes status, or by race, and was not correlated with a change in phosphorus, age, or urea reduction ratio at 1 month following hemodialysis initiation. Decreased CRP was associated with increased hemoglobin and albumin. Patients with persistent fistula use from dialysis initiation through 6 months had consistently low CRP levels over that time period. Our study shows that catheters might contribute to increased inflammation independent of infection, and supports avoidance of catheters and a timely conversion to fistulas with catheter removal.

    A colopleural fistula is a rare condition reported to be caused by Crohn's disease, a malignant tumor of the gastrointestinal tract, and other clinical conditions. Some studies have noted that a sub-diaphragmatic abscess, usually organized following abdominal surgery, may play some role in the formation of this type of fistula. Therefore, a colopleural fistula is a complication very rarely encountered by thoracic surgeons after lung resection.We experienced an extremely rare case of colopleural fistula following a left lower lobectomy for lung aspergillosis. Here, we report a 71-year-old man with a surgical history of proximal gastrectomy for gastric cancer. He underwent left lower lobectomy of the lung for aspergillosis, and a colopleural fistula occurred on the second operative day as a complication. Aspergillus might be responsible for forming a fistula between the colon and lung via the diaphragm, and lung surgery manifested this rare condition. Although some reports suggest that surgical treatment is mandatory to cure this fistula, an immediate colostomy in our case reduced the internal pressure of the colon, thus enabling spontaneous closure of the fistula with appropriate drainage and antibiotics. The patient was discharged in a good condition.

    Enterocutaneous fistula is a challenging clinical condition with serious complications and considerable morbidity and mortality. Early nutritional support has been found to decrease these complications and to improve the clinical outcome. Location of the fistula and physiological status affect the nutrition management plan in terms of feeding route, calories, and protein requirements. This study investigated the nutritional management procedures at the Universiti Kebangsaan Malaysia Medical Center, and attempted to determine factors that affect the clinical outcome. Nutritional management was evaluated retrospectively in 22 patients with enterocutaneous fistula seen over a 5-year period. Medical records were reviewed to obtain data on nutritional status, biochemical indices, and route and tolerance of feeding. Calories and protein requirements are reported and categorized. The results show that surgery was the predominant etiology and low output fistula was the major physiological category; anatomically, the majority were ileocutaneous. The spontaneous healing rate was 14%, the total healing rate was 45%, and the mortality rate was 22%, with 14% due to fistula-associated complications. There was a significant relationship between body mass index/serum albumin levels and fistula healing; these parameters also had a significant relationship with mortality. Glutamine was used in 50% of cases; however, there was no significant relationship with fistula healing or mortality rate. The nutritional status of the patient has an important impact on the clinical outcome. Conservative management that includes nutrition support is very important in order to improve nutritional status before surgical repair of the fistula.

    The formation of an appendico-cutaneous fistula is rare. Few case reports have been published; most describe the formation of a fistula after appendicitis. Here we describe the case of a 79-year-old woman presenting with an appendico-cutaneous fistula after groin hernia repair. She was referred to our outpatient department with a painful mass in the right groin. An ultrasound showed a fluid containing mass. Incision and drainage was performed. After 9 weeks she was referred again with a persisting open wound. Fistulogram and CT scan showed a fistuleous tract involving the appendix. Wound culture showed Escherichia coli. Diagnostic laparoscopy showed an appendix stuck to the ventral wall of the abdomen without any sign of previous infection. After an appendectomy, pathological investigation revealed an appendix sana. After operation, the fistula persisted due to a polypropylene plug from the previous groin hernia correction. The (infected) plug was removed and the fistula healed. PMID:23921697

    A patient with an abdominal aortic aneurysm with a preaortic left renal vein fistula is presented. Review of the 7 reported cases of aorto-left renal vein fistulae demonstrates many similarities in the clinical presentation with aorto-caval fisulae. However, in addition to the triad of pain, pulsatile abdominal mass and bruit, commonly found in aorto-caval fistulae, the presence of hematuria, proteinuria, and azotemia suggests a renal vein fistula. Radiographic studies often demonstrate a large non-functional left kidney. Operative management of the fistula may be performed by a variety of maneuvers. All 7 patients survived. When repair was undertaken without delay, function in the left kidney returned to normal within two months postoperatively. Images Fig. 1. Fig. 3. PMID:938115

    A subclavian artery-esophageal fistula usually occurs on the right side of an aberrant subclavian artery. It also rarely appears in the site between a non-aberrant subclavian artery and the esophagus due to the ingestion of a foreign body. Upper gastrointestinal bleeding in the case of a subclavian artery-esophageal fistula is rare but often fatal. Here, we report on a 62-year-old male patient with a left subclavian arteryesophageal fistula complicated by hemorrhagic shock. He swallowed a foreign body at a birthday party. An upper gastrointestinal endoscopy indicated a paper star lodged at 20 cm from the incisors, inducing a kissing esophageal ulcer around the esophageal sphincter. One month later, he suffered an unusually strong episode of hematemesis. Subsequently, a computed tomography angiography was performed and demonstrated a left subclavian artery-esophageal fistula. Finally, the fistula induced by the ingestion of a paper star was successfully treated by endovascular stent grafting. PMID:27514535

    We report four cases in which a pericardium (Tutoplast) plug was used to repair a corneoscleral fistula after Ahmed Glaucoma Valve (AGV) explantation. In four cases in which the AGV tube had been exposed, AGV explantation was performed using a pericardium (Tutoplast) plug to seal the defect previously occupied by the tube. After debridement of the fistula, a piece of processed pericardium (Tutoplast), measured 1 mm in width, was plugged into the fistula and secured with two interrupted 10-0 nylon sutures. To control intraocular pressure, a new AGV was implanted elsewhere in case 1, phaco-trabeculectomy was performed concurrently in case 2, cyclophotocoagulation was performed postoperatively in case 3 and anti-glaucomatous medication was added in case 4. No complication related to the fistula developed at the latest follow-up (range: 12-26 months). The pericardium (Tutoplast) plug seems to be an effective method in the repair of corneoscleral fistulas resulting from explantation of glaucoma drainage implants.

    This case report describes a novel approach to the repair of perineal urethrocutaneous fistulae (UCF) after abdominoperineal resection (APR). A 62-year-old patient developed a UCF after an APR for rectal cancer complicated by perineal abscess formation. The patient presented with continuous urinary drainage from the fistula that persisted despite a number of conservative and surgical measures. The patient underwent successful repair of the urethrocutaneous fistula in prone position—an approach that has not previously been described in the literature. Repair was performed by the multi-disciplinary team of a reconstructive urologist, colorectal surgeon, and plastic surgeon. Post-operative retrograde urethrogram demonstrated the absence of a persistent fistula tract and the patient has been continent for 18 months. The prone approach for UCF repair allows for excellent access to the fistula tract for posterior urethroplasty in a patient that has had prior APR. PMID:26834897

    A review of patients undergoing aortic aneurysmectomy between 1970 and 1979 at the Emory University Hospital and the Atlanta Veterans Administration Medical Center disclosed six patients with aortovenous fistulas. Four fistulas were aorta to vena cava; one, aorta to left renal vein; and one, aorta to left iliac vein. Four of the arteriovenous fistulas were identified preoperatively. In another patient the symptoms and signs were masked by concomitant retroperitoneal rupture of the aneurysm. The final patient was asymptomatic preoperatively, but had an occluded fistula discovered at operation when laminated thrombus was removed from the wall of the aneurysm. One patient died while being prepared for operation; five were operated upon and survived. Successful management of this problem is contingent upon preoperative recognition, careful manipulation of the aneurysm with endoaneurysmal closure of the fistula, and judicious perioperative fluid management.

    Acquired eso-respiratory fistulae are usually consecutive to an eso-tracheal or an eso-bronchial fistula. Esophago-pulmonary fistulae have been rarely described. We report a case of esophago-pulmonary fistula in a patient with esophageal carcinoma. Our patient presented progressive necrotizing pneumonia. CT scan of the thorax demonstrated necrosis of the esophagal wall and communication between the esophagus and the lung parenchyma. Furthermore, the biochemical analysis of the lung abcess fluid revealed a high level of amylase. Outcome was poor despite drainage of the lung abcess and insertion of an esophageal stent. Based on this case, we reviewed the cases of esophago-pulmonary fistulae described in the literature.

    An intracranial dural arteriovenous fistula(dAVF)was incidentally detected in a 39-year-old man during a medical checkup. Except for a mild episode of pneumonia at the age of 22 years, his medical history was unremarkable. He had no family history of hereditary hemorrhagic telangiectasia(HHT). The dAVF was treated radically via ligation of the fistula, without any complications. Postoperative angiography demonstrated that the dAVF had completely healed, but showed an aberrant, dilatated, and tortuous internal mammary artery. A contrast-enhanced computed tomography scan revealed multiple arterio-arterial fistulas between various systemic arteries and the pulmonary artery(an intercostal artery to the pulmonary artery fistula, an internal mammary artery to the pulmonary artery fistula, and an inferior phrenic artery to the pulmonary artery fistula). These thoracic lesions did not require additional treatment because they did not cause any symptoms, e.g., respiratory or cardiac failure. In most previous cases, such aberrant thoracic arterial fistulas were detected incidentally or based on the presence of minor clinical symptoms. However, in some cases, they caused severe respiratory or cardiac failure and were treated via the embolization of the responsible vessels. Therefore, the co-existence of thoracic arterial fistulas in patients with dAVF should be evaluated, even if the dAVF does not meet the criteria for HHT. Such thoracic lesions might cause a chest murmur that can be detected via a stethoscope or via a blunt costophrenic angle on chest radiography. PMID:27605480

    Here we present a case of successful non-operative management of an iatrogenic recto-urethral fistula in a 13-year-old boy. The fistula was created when urethroscopic repair of a urethral stricture was attempted. Due to the anatomy of the lesion and previous urinary diversion, it was deemed possible to spare this patient diverting colostomy or surgical repair of the fistula. The result was successful closure of the fistula, which was confirmed on retrograde urethrogram. While we do not support the routine use of non-operative management for recto-urethral fistulas we have demonstrated that there are circumstances where it can be safely applied.

    Crohn's disease is a type of chronic inflammatory bowel disease (IBD) of unknown etiology that may affect any part of the gastrointestinal tract from mouth to anus and shows extra-intestinal involvement. It characteristically shows skip lesions. This case report reported in 2014 describes a middle age Pakistani male known to have documented evidence of significant crohn's disease since past 18 years. He was diagnosed with multiple fistulas that are a rare entity of patients with crohn's disease, which is itself a rare disease in Asian countries. PMID:26744714

    The spinal dural arteriovenous fistula (SDAVF) is rare, presenting with progressive, insidious symptoms, and inducing spinal cord ischemia and myelopathy, resulting in severe neurological deficits. If physicians have accurate and enough information about vascular anatomy and hemodynamics, they achieve the good results though the surgery or endovascular embolization. However, when selective spinal angiography is unsuccessful due to neurological deficits, surgery and endovascular embolization might be failed because of inadequate information. We describe a patient with a history of vasospasm during spinal angiography, who was successfully treated by spinal stereotactic radiosurgery using Novalis system. PMID:27446527

    Acquired tracheo-oesophageal fistula (TEF) after tracheostomy is a life threatening complication and can occur in about 1% of cases of tracheostomy. Percutaneous tracheostomy was performed in intensive care unit on a 40 years male patient for long-term mechanical ventilation. Subsequently patient developed TEF as the complication of tracheostomy. He was initially managed with endoscopically inserted self expanding plastic stent but later on required surgery for definitive repair. The problems associated with acquired TEF and its management are discussed hereby. PMID:26522209

    Physical examination has demonstrated its effectiveness in identifying complications of arteriovenous fistula (AVF). It should be initiated at the stage prior to the construction of the AVF and continue in its accomplishment, maturation, and subsequent use in the treatment of hemodialysis. Nurses should incorporate the physical examination in their practices, in order to preserve the vascular net of patients and assist in the recognition of complications of AVF. It is intended to describe aspects of the physical examination that enable the identification of the AVF complications including: infection, accessory veins, venous stenosis, steal syndrome, high-output cardiac failure, and venous hypertension.

    2016-01-01

    Hydrothorax secondary to a pancreaticopleural fistula (PPF) is a rare complication of acute pancreatitis. In patients with a history of pancreatitis, diagnosis is made by detection of amylase in the pleural exudate. Imaging, particularly magnetic resonance cholangiopancreatography, aids in the detection of pancreatic ductal disruption. Management includes thoracocentesis and pancreatic duct drainage or pancreatic resection procedures. We present a case of massive right hydrothorax secondary to a PPF due to recurrent acute pancreatitis. Due to respiratory failure, urgent thoracocentesis was done. Distal pancreatectomy with splenectomy and cholecystectomy was performed. The patient remains well at one-year follow-up. PMID:27747128

    Summary We present an alternative endovascular approach to treat dural carotid cavernous fistulae (dural CCF) that drain only into the superior ophthalmic vein. Four cases of cavernous dural AVFs that could not be treated via the inferior petrosal vein were accessed via the direct superficial temporal vein approach through the superior ophthalmic vein. Successful embolization was documented radiographically and clinically in all patients. The trans-superficial temporal vein approach is safe and useful for inaccessible dural CCFs through the inferior petrosal sinus. PMID:20566079

    This study aimed to present the treatment of a case of delay presenting of traumatic aortocaval fistula (ACF) and its effect on hemodynamic problem. A 59-year-old man was admitted to our hospital with heart failure due to a 41-year-old traumatic ACF. ACF closure was performed by endovascular aortic stenting. His hospital course after procedure was complicated by severe bradycardia and torsades de pointes and excessive diuresis. We concluded the endovascular technique provided an attractive alternative to open surgical methods for repair of chronic ACF. However, in chronic cases, complications such as severe bradycardia (Nicoladoni-Branham sign) and excessive diuresis must be anticipated. PMID:24386026

    Arteriovenous fistula (AVF) formation after penetrating trauma is a well-described phenomenon. However, diagnosis of traumatic AVF is frequently delayed as patients often do not have hard signs of vascular injury at the initial presentation. Late complications of traumatic AVF include arterial and venous dilatation, distal ischemia, venous congestion, and congestive heart failure. This case report describes a traumatic femoral AVF causing distal venous ulceration 3 years after the injury. The AVF was treated with open repair. In the operating room, the Nicoladoni-Branham sign was elicited. The ulcer healed at 1 month and has not recurred at 1-year follow-up.

    Pancreaticopericardial fistula (PPF) is an extremely rare clinical problem encountered in patients with chronic pancreatitis. The diagnosis should be suspected if a patient presents with pericardial effusion on a background of chronic pancreatitis. Significantly raised amylase in the pericardial fluid offers an important clue for the diagnosis. CT is the initial imaging modality to look for pancreatic and pericardial changes. The therapeutic options include medical, endoscopic or surgical interventions. Medical and endoscopic therapies are the preferred modes of treatment while surgery is reserved for those who fail these measures. PMID:27190118

    Coccidioidomycosis (valley fever) is caused by the dimorphic fungi Coccidioides immitis or Coccidioides posadasii. Most infections are asymptomatic or result in self-limited pneumonia; extrapulmonary dissemination via either hematogenous or lymphatic spread is rare. Here, we present a case of cervical C. immitis lymphadenitis that resulted in fistula formation to the esophagus via mediastinal extension. This case highlights a very unusual extrapulmonary manifestation of coccidioidomycosis, the difficulty in diagnosing coccidioidal infection when it is not suspected, and the importance of obtaining a thorough exposure history to assist with diagnosis.

    The oroantral fistula (OAF) is an epithelialized communication between the oral cavity and the maxillary sinus. In most of the cases, this communication occurs after molars and premolars extractions, but other factors may be cause of the communication, such as trauma. This article demonstrates an alternative surgical technique illustrated with a case report in which we perform the surgical treatment of OAF with palatal flap rotation combined with the use of titanium mesh in a victim of gunshot projectile wound in oral cavity.

    The authors describe the case of a 44-year-old woman who presented with recent onset of progressive paraparesis and bladder involvement; she had an asymptomatic lumbosacral lipomatous swelling that was present since birth. Magnetic resonance imaging confirmed the diagnosis of a lipomeningocele. It also revealed intramedullary hyperintensity on T2-weighted images and serpiginous flow voids suggestive of a dural arteriovenous fistula (DAVF) at the same level; the lesion was confirmed by spinal angiography. Both lesions were surgically managed, and the patient subsequently experienced neurological improvement. The coexistence of a DAVF and a lipomeningocele at the same level is unusual and can lead to treatment failure if missed.

    Esophageal duplication (ED) is rarely diagnosed in adults and is usually asymptomatic. Especially, ED that is connected to the esophagus through a tubular communication and combined with bronchoesophageal fistula (BEF) is extremely rare and has never been reported in the English literature. This condition is very difficult to diagnose. Although some combinations of several modalities, such as upper gastrointestinal endoscopy, esophagography, computed tomography, magnetic resonance imaging, and endoscopic ultrasonography, can be used for the diagnosis, the results might be inconclusive. Here, we report on a patient with communicating tubular ED that was incidentally diagnosed on the basis of endoscopy and esophagography during the postoperational evaluation of BEF. PMID:26855929

    A perilymphatic fistula (PLF) is an abnormal communication between the inner and middle ear resulting in vestibular or cochlear symptoms. We review three pediatric traumatic temporal bone fractures with pneumolabyrinth, confirmed radiologically by the presence of air within the cochlea (pneumocochlea) or vestibule (pneumovestibule). Patients were treated conservatively with complete resolution of vestibulopathy. Hearing outcome was variable and worse in two patients with pneumocochlea. A pneumolabyrinth on radiologic imaging confirms a PLF and obviates the need for exploration to reach a diagnosis. We suggest exploration be reserved for patients with persisting cerebrospinal fluid leakage, progressive sensorineural hearing loss, or vestibular symptomatology.

    Transcatheter embolization of renal angiomyolipomas is a routinely performed, nephron-sparing procedure with a favorable safety profile. Complications from this procedure are typically minor in severity, with postembolization syndrome the most common minor complication. Abscess formation is a recognized but uncommon major complication of this procedure and is presumably due to superinfection of the infarcted tissue after arterial embolization. In this case report, we describe the formation of a renoduodenal fistula after embolization of an angiomyolipoma, complicated by intracranial abscess formation and requiring multiple percutaneous drainage procedures and eventual partial nephrectomy.

    The medial tentorial artery arises from the meningohypophyseal trunk, a branch of the cavernous internal carotid artery, and it is poorly visualized on angiography in the absence of pathologically increased blood flow. We present the case of a 38-year-old man with intraventricular hemorrhage from a tentorial dural arteriovenous fistula (DAVF) singularly supplied by a robust medial tentorial artery. Tentorial DAVFs comprise a rare but high-risk subset of DAVFs. The diagnosis was suggested by computed tomography and magnetic resonance imaging findings and confirmed with digital subtraction angiography. PMID:27594958

    Thirteen patients with malignant colovesical fistulae are presented. The underlying pathology was cancer of the colon (seven cases), bladder (four cases) and cervix (two cases). The series demonstrates that wide surgical excision may be needed to achieve tumour clearance and that this may necessitate pelvic exenteration. Three patients who underwent inadequate tumour excision developed recurrence in the bladder, two with a fatal outcome. Wide excision of the bladder may be performed without urinary diversion by subtotal cystectomy and a reconstructive procedure. Substitution cystoplasty was performed on two patients at the time of tumour excision. Urinary tract involvement by such tumours is often extensive and optimal results may be achieved with a multidisciplinary approach.

    2012-01-01

    BACKGROUND: The mainstay of therapy for gastrocutaneous (GC) fistulas has been surgical intervention. However, endoclips are currently used for management of perforations and fistulas but are limited by their ability to entrap and hold the tissue. OBJECTIVE: To report the first North American experience with a commercially available over-the-scope clip (OTSC) device, a novel and new tool for the endoscopic entrapment of tissue for the closure of fistula and perforations. METHODS: The present single-centre study was conducted at a tertiary referral academic gastroenterology unit and centre for advanced therapeutic endoscopy and involved patients referred for endoscopic treatment for the closure of a GC fistula. The OTSC device was mounted on the tip of the endoscope and passed into the stomach to the level of the fistula. The targeted site of the fistula was grasped with the tissue anchoring tripod and pulled into the cap with concomitant scope channel suction. Once the tissue was trapped in the cap, a ‘bear claw’ clip was deployed. RESULTS: The patients recovered with fistula closure. No complication or recurrence was noted. Fistula sizes >1 cm, however, were difficult to close with the OTSC system. The length of stay of the bear claw clip at the fistula site is unpredictable, which may lead to incomplete closure of the fistula. CONCLUSION: Closure of a GC fistula using a novel ‘bear claw’ clip system is feasible and safe. PMID:22506258

    Purpose: This retrospective review aimed to report the outcomes of arteriovenous fistula (AVF) and to evaluate the suitability of AVF as a permanent vascular access in pediatric populations. Materials and Methods: Data were collected for all patients aged 0 to 19 years who underwent AVF creation for hemodialysis between January 2000 and June 2014. Results: Fifty-two AVFs were created in 47 patients. Mean age was 15.7±3.2 years and mean body weight was 46.7±15.4 kg. Of the 52 AVFs, 43 were radiocephalic AVFs, 7 were brachiocephalic AVFs and 2 were basilic vein transpositions. With a mean follow-up of 49.7±39.2 months, primary patency was 60.5%, 51.4%, and 47.7% at 1, 3, and 5 years, respectively and secondary patency was 82.7%, 79.2% and 79.2% at 1, 3, and 5 years, respectively. Age, body weight, AVF type, the presence of a central venous catheter, use of anticoagulation therapy, and history of vascular access failure were not significantly associated with patency rates. There were 9 cases (17.3%) of primary failure; low body weight was an independent predictor. Excluding cases of primary failure, the mean duration of maturation was 10.0±3.7 weeks. During follow-up, 20 patients (42.6%) underwent kidney transplantation, with a median interval to transplantation of 36 months. Conclusion: AVF creation in children and adolescents is associated with acceptable long-term durability, primary failure rate and maturation time. Considering the waiting time and limited kidney graft survival, placement of AVFs should be considered primarily even in patients expected to receive transplantation. PMID:27699158

    Objective An obstetric fistula is a childbirth injury resulting in uncontrollable leakage of urine and/or feces and can lead to physical and psychological challenges, including social isolation. Prior to and after fistula repair surgery, social support can help a woman to reintegrate into her community. The aim of this study was to preliminarily examine the experiences of social support among Tanzanian women presenting with obstetric fistula in the periods immediately preceding obstetric fistula repair surgery and following reintegration. Patients and methods The study used a mixed-methods design to analyze cross-sectional surveys (n=59) and in-depth interviews (n=20). Results Women reported widely varying levels of social support from family members and partners, with half of the sample reporting overall high levels of social support. For women experiencing lower levels of support, fistula often exacerbated existing problems in relationships, sometimes directly causing separation or divorce. Many women were assertive and resilient with regard to advocating for their fistula care and relationship needs. Conclusion Our data suggest that while some women endure negative social experiences following an obstetric fistula and require additional resources and services, many women report high levels of social support from family members and partners, which may be harnessed to improve the holistic care for patients.

    Thirty-eight patients with external gastrointestinal fistulas arising from different levels of the gastrointestinal tract, observed and treated at the Massachusetts General Hospital, from December 1970 to April 1973, are analyzed. Surgical complications were the causes of fistulization in 77% of the cases. The treatment program included parenteral nutrition through a subclavian line in all cases. The 38 patients were fed parenterally for a total of 2311 days. Spontaneous fistula closure occurred in only 11 of the 38 patients. Surgical procedures were necessary in 71.05% of the cases to control fistula complications or persistent fistula drainage. Operative success rate was 70.4%. Parenteral nutrition effects on metabolic parameters, fistula secretion, nutritional status, morbidity and mortality of fistulas are discussed. Parenteral nutrition hazards are also presented. Overall mortality in this series was 21%. Roles of parenteral nutrition and surgery in the total management of external gastrointestinal fistulas are suggested.

The mechanism of such fistula is thought to be related to a previously untreated ulcer in the mucosa of the wall of the gastric wrap or to a subclinical injury to the gastric wall during the process of division of the short gastric vessels and gastric mobilization. This process is greatly aided by herniation of the wrap into the chest in the postoperative period, placing the stomach in intimate contact with the bronchial tree. The diagnosis of GBF is often difficult to establish and requires a high index of suspicion. Most investigative studies tend to be unrevealing. Historically, an upper gastrointestinal series was the recommended study of choice in the literature. Newer reports, however, highlight the value and importance of upper endoscopy as a diagnostic tool in this condition. The majority of GBF were reported in the era of transthoracic Nissen fundoplication. The incidence of this complication seems to have markedly decreased after the widespread adoption of the transabdominal approach to the treatment of GERD. We are reporting the second case in the literature of a GBF developing after a laparoscopic Nissen fundoplication in a 28-year-old male patient. This case report should serve to increase awareness of this uncommon complication that should be considered in the differential diagnosis of patients with recurrent pneumonia or refractory hemoptysis after major upper gastrointestinal surgical procedures.

    In the modern era, the incidence of rectourethral fistula (RUF) has been on a rise due to an increasing number of surgeries being performed for prostatic carcinoma. Other causes of this condition still remain rare and their management differs from that of post prostatectomy RUF. We report a rare case of a young man who presented with leakage of urine per rectum 4 weeks after injection sclerotherapy for haemorrhoids. A Micturating Cystourethrogram/Retrograde Cystourethrogram revealed the presence of RUF arising at the level of prostrato-membranous urethra and the urine examination did not show any fecal contamination of urine. A fistula at the level or verumontanum along with stricture of the distal penile urethra was demonstrated on urethroscopy. The patient was successfully managed by dilatation of the stricture segment and urethral catheterization. RUF can rarely result from injection sclerotherapy and must be thoroughly evaluated. Cases which present early and have minimal contamination of urine by fecal contents can be conservatively managed with a simple Foleys catheterization for 4-6 weeks after ruling out any obstruction distal to the fistulous tract.

    Oesophago-respiratory fistula in most instances in a complication of advanced malignant tumours of the oesophagus or the lung. In our patient group eleven oesophago-respiratory and one gastro-respiratory fistulas were encountered. Three patients were operated upon. In one of them with achalasia, early oesophageal carcinoma was discovered in the background of the fistula. Two patients had fistulas without of oesophageal narrowing, therefore, stent implantation into the trachea and bronchus was performed. One of them was previously managed endoscopically with lyodura plug and fibrin glue, but only temporary occlusion of the fistula was obtained. In five patients, seven conventional oesophageal prosthesis (6 Cook, 1 Rüsch) were used to close the fistulas. In one of these patients, three oesophago-respiratory fistulas developed one after the other at the level of the prosthesis funnel. They were closed with three prostheses connected with short silicone tubes. In the last two patients, Gianturco-Z stent was employed. Its advantages over the plastic prostheses include small basic and lager final luminal diameter, lesser predilatation, easier implantation, lower complication and mortality rate. The silicone coated and double funnel stent with expansile force is effective in fistulas closure. On implantation, stent shortening in minimal, allowing precise placement of the stent even in proximal malignant oesophageal stenosis with oesophago-bronchial fistula. The high price of the stent is compensated for by the lower complication rate, shorter hospitalization and subsequent reduction is hospital expenses. Therefore these metal stents should be financed by the National Health Service, at least in specialized centers for managing patients with dysphagia. PMID:9805459

    Background: Spinal dural AVF is the most common type of spinal vascular malformation. However, presenting symptoms differ according to site of spinal involvement. This study described a case of arteriovenous malformation with paraparesis and incontinence. Case Presentation: Diagnosis of patient was confirmed by clinical and imaging examination using magnetic resonance image and ruling out other possibilities Result: A definitive diagnosis of arterio venous fistula was confirmed by clinical and MRI examination and demonstrated abnormalities compatible with dural arteriovenous fistula. Conclusion: Dural arteriovenous fistula should be considered in patients with paresis in both lower extremities. PMID:27757211

    Coronary-cameral fistulas are rare cardiovascular anomalies. A giant coronary artery aneurysm associated with a coronary-cameral fistula is a very rare condition, with an estimated prevalence of 0.02%. We report the case of middle-aged woman who presented with a huge extracardiac aneurysmal mass and a coronary-cameral fistula from a right coronary artery branch. It was successfully repaired by ligation and excision plus marsupialization of the aneurysm. We believe this is the first such a case reported in literature.

    An oronasal fistula is described in a 53-year-old captive hippopotamus, the animal having shown a nasal discharge, consisting mainly of food particles, during and after feeding for at least 15 years. Necropsy of the emaciated animal revealed an oronasal fistula, measuring 4.5 x 3.5 cm, adjacent to the third left molar tooth, the first and second molars being missing. The fistula was thought to have been caused by an earlier necrotizing alveolitis and osteitis. There was no evidence of rhinitis or aspiration pneumonia. Unrelated findings consisted of a follicular thyroid adenoma and generalized muscle atrophy.

    The authors, on the basis of a long clinical experience with human fibrin glue in general surgery, compared two different extracellular matrix (collagen), Surgisis and TissueDura, with human fibrin glue, applied during the operation, and sometimes in postoperative, to obtain the healing of perianal fistulas. The collagenic extracellular matrix provides, according to the rationale suggested, an optimal three-dimensional structure for the fibroblastic implant and neoangiogenesis, hence for the fistula "fibrotizzation" and closure. The encouraging results for transphincteric fistulas and a simple and easy technique push to researchers on samples statistically significant. PMID:19272233

    Summary: The management of recurrent rectovaginal fistula after obstetric injury and cryptoglandular sepsis is considered a major surgical challenge. The fistula poses a significant negative psychosocial and sexual morbidity. In addition, the poor quality of local tissues due to previous attempts at surgical repair adds to this challenge. There are few data regarding the management of persistent or recurrent fistula in the literature; however, several studies reported high failure rates after 2 or more procedures. We present 4 cases managed successfully in a multidisciplinary approach involving fistulectomy and immediate reconstruction with an internal pudendal artery perforator island flap.

    Esophago-respiratory fistulas (ERF) do not close spontaneously and are uniformly fatal. A somatostatin analogue (octreotide acetate) was used in three consecutive patients to promote the closure of ERF. In 2 patients with esophageal cancer, treatment with octreotide acetate was associated with fistula closure in 30 and 46 days, respectively. In a third patient with virally-induced ERF, treatment was associated with improvement of the inflammation of the fistula before the patient's death from pulmonary aspiration after 40 days of treatment. These preliminary observations suggest that octreotide acetate treatment of ERF should receive further investigative scrutiny.

    We present a typical case of acute suppurative thyroiditis (AST), associated with a piriform sinus fistula. We illustrate the case with an ultrasound picture of a hypoechogenic perithyroid mass and a CT scan using intravenous iodine contrast showing a perithyroid hypodense mass with peripheral enhancement, the mass also having intrathyroid involvement. When clinical and radiological findings suggest the presence of AST, it is necessary to rule out the presence of a piriform sinus fistula by means of a radiological study with barium contrast. Piriform sinus fistula is a rare abnormality derived from the branchial arch which is directly related to recurrent episodes of AST; surgical excision is hence, necessary to avoid such episodes.

    A 57-year-old woman presented with effort angina. A coronary angiogram revealed critical 2-vessel disease, for which she subsequently underwent percutaneous coronary intervention. During angioplasty, a coronary guidewire—inadvertently passed into the right ventricle through the septal branches of the posterior descending coronary artery—caused a coronary artery-to-right ventricular fistula. This fistula was successfully closed percutaneously by coil embolization. To our knowledge, this is the first report of a case in which a coronary artery-to-right ventricular fistula caused by a guidewire was managed successfully by coil embolization. PMID:27547147

    Context • For patients undergoing hemodialysis, the native arteriovenous fistula (AVF) is the primary approach to vascular access (VA). VA failure is the main cause of morbidity and mortality in hemodialysis patients. It has been reported in recent studies that the primary failure rate can be as high as 50%. Objective • The study investigated the effects of iontophoretic administration of Salvia miltiorrhiza (SM) on the maturation of the AVF. Design • The study was a randomized, controlled trial. Setting • The study occurred in Guangdong Provincial Hospital of Traditional Chinese Medicine (Guangzhou, China). Participants • Participants were 40 patients with chronic kidney disease at stage 4 or 5. Intervention • Participants were randomly assigned to one of 2 groups (n = 20 each) after they had received an AVF operation. Patients in the control group were given routine care, and patients in the intervention group were given routine nursing in combination with an iontophoretic SM injection on a targeted area of the fistula after surgery. Outcome Measures • The blood flow of the AVF, the diameter of the artery vein shunt, and the thickness of the AVF from the vascular wall to the skin were observed. Results • The maturation rates of the AVFs after 1 mo were 50% and 85% in the control group and the intervention group, respectively. A significant difference existed between the 2 groups (P < .05). The results of the surgery were significantly different for the control and intervention groups, with the blood flows of the AVF being 1182.05 ± 547.10 mL/min and 705.55 ± 278.63 mL/min (P < .05), respectively, and the diameters of the artery vein shunts being 4.51 ± 1.47 mm and 3.54 ± 0.67 mm (P < .05), respectively, after treatment. Conclusions • Iontophoretically mediated, transdermal delivery of an SM injection to a targeted area of the AVF can significantly shorten the time to maturity of the fistulae. PMID:27622956

    Background: Thoracoscopic treatment of esophageal atresia and tracheoesophageal fistula (EA+TEF) is accepted as a superior technique at least in cosmetic point of view but it is considered as an advance endoscopic procedure that needs a learning curve to be performed perfectly. This is the first report of Iranian group pediatric surgeons in thoracoscopic approach to EA. Methods and Materials: Since 2010, twenty four cases with EA+TEF underwent thoracoscopic approach in Sarvar Children Hospital (Mashhad -Iran). During the first 6 months, thoracoscopic approach to 6 cases of EA+TEF was converted to open procedure because of technical and instrumental problems. The first case of successful thoracoscopic EA repair was accomplished in 2010 and since then, 10 cases of EA+ TEF among 18 patients were treated successfully with thoracoscopic approach Results: Overall conversion rate was 58.3% but conversion rate after the primary learning curve period, was 35.7%. The main conversion causes include difficulties in esophageal anastomosis, limited exposure and deteriorating the patient's condition. Anastomotic leak and stenosis were observed in 20% and 40% respectively. Overall mortality rate was 4.2%. Conclusion: Thoracoscopic repair of esophageal atresia seems feasible and safe with considerable superiorities to the conventional method although acceptable results needs a prolonged learning curve and advanced endoscopic surgical skill. Clear judgment about the best surgical intervention for EA according to all cosmetic and functional outcomes needs further studies. PMID:27471677

    A 33-year-old man fell from a height and was referred to our hospital. Physical examination showed a swelling in the left preauricular region without laceration. No thrill or bruit was detected at this time. A face x-ray and a computed tomographic scan showed a left temporomandibular joint (TMJ) dislocation, Le Fort I fractures, and a mandibular body fracture. Left TMJ dislocation was treated by manual reduction. Two days after admission, a swelling in the left preauricular region progressed, with thrill and bruit. Left external carotid artery angiograms showed an arteriovenous fistula with a dilated pouch near the left TMJ. The fistula was fed by the left superficial temporal artery and drained into the left superficial temporal vein. The fistula was successfully embolized using Tornado coils. This is the first case of an arteriovenous fistula of the superficial temporal artery after manual reduction of TMJ dislocation. PMID:21959481

    Urinary fistulas, abnormal openings of a urinary tract organ, are serious complications and conventional management strategies are not satisfactory. For more effective and non-invasive fistula repair, fluid tissue adhesives or sealants have been suggested. However, conventional products do not provide a suitable solution due to safety problems and poor underwater adhesion under physiological conditions. Herein, we proposed a unique water-immiscible mussel protein-based bioadhesive (WIMBA) exhibiting strong underwater adhesion which was employed by two adhesion strategies of marine organisms; 3,4-dihydroxy-l-phenylalanine (DOPA)-mediated strong adhesion and water-immiscible coacervation. The developed biocompatible WIMBA successfully sealed ex vivo urinary fistulas and provided good durability and high compliance. Thus, WIMBA could be used as a promising sealant for urinary fistula management with further expansion to diverse internal body applications. PMID:26352517

    Vertebrovertebral fistulae are rare vascular malformations that uncommonly can rupture to present clinically as intracranial subarachnoid hemorrhage. We report a 69-year-old man presenting following spontaneous apoplectic collapse. Initial workup revealed diffuse, intracranial subarachnoid hemorrhage, intraventricular hemorrhage and hydrocephalus. However, the etiology was not apparent on CT angiography of the head. Catheter-based angiography was performed, demonstrating a single-hole, high-flow vertebrovertebral fistula, arising from the V2 segment and decompressing into both cervical and skull base venous structures. Definitive treatment consisted of endovascular fistula obliteration with a combination of coil and liquid embolic material. The patient made a full neurological recovery. High cervical and skull base fistulae are rare causes of intracranial hemorrhage; endovascular treatment is effective at disconnection of the arteriovenous shunt.

    Thoracic endovascular aortic repair for thoracic aortic aneurysms is an accepted alternative to open surgery, especially in patients with significant comorbidities. The procedure itself has a low risk of complications and fistulas to surrounding organs are rarely reported. An 86-year-old patient was admitted to our hospital with gastro intestinal (GI) bleeding and a suspected aortoesophageal fistula. Eight months prior, the patient had undergone a stent graft repair of a mycotic thoracic aneurysm. Computerized tomography angiography and upper GI endoscopy confirmed an aortoesophageal fistula, which was treated by esophageal stenting. With early recognition, esophageal stenting may have a role in the initial emergency control of bleeding from and palliation of aortoesophageal fistula. PMID:27574612

    Carotid-cavernous fistulas are an uncommon diseases characterized by abnormal communications between arteries and veins located in the cavernous sinus. According with Barrow´s classification they could be divided in two groups: direct and indirect. The typical symptoms showed by theses pathologies are: pulsating exophthalmos and orbital blow. The present study describes a case of direct posttraumatic carotid-cavernous fistula in a 26 years old man. Furthermore, we present the images that we used to make the diagnosis. In this light, we decided to treat this case with endovascular approach after considering several therapeutic options. The aim of the present report is twofold. First, we examine the importance of the proper management of the direct posttraumatic carotid-cavernous fistula. Second, we describe this rare syndrome with the goal of proposing suitable treatments.

    This study examines the use of laparoscopic upper rectovaginal mobilization to facilitate the transvaginal repair of recurrent rectovaginal fistulas. A 39-year-old female presented with fecal and gas incontinence consequent to an obstetrically related rectovaginal fistula with five unsuccessful transvaginal repairs over a 5-year period. Her condition was successfully treated by a transphincteric approach that combined an extensive laparoscopic dissection of the rectovaginal space from above with transvaginal dissection of the rectovaginal space from below to create complete mobilization between the two organs and to permit an excellent, tension-free closure of the rectal defect. Successful fistula closure and restoration of anal continence were achieved. The patient remains cured 18 months postsurgery. Laparoscopic mobilization of the upper rectovaginal septum followed by transvaginal division of the lower septum permits a more extensive mobilization and release of tension for fistula repair than that typically noted by the vaginal route alone.

    A fistula is an abnormal vascular connection leading to diversion of blood from a high resistance arterial circuit to low resistance venous circuit. Coronary artery fistulas are abnormal communications of the coronary artery with a chamber of the heart, or with any segment of systemic or pulmonary circulation, bypassing the myocardial capillaries. Other unusual fistulas include connection between aorta and the right atrium/superior vena cava, aorta and the inferior vena cava or between a coronary artery bypass graft and a cardiac vein. Abnormal connections also include origin of the coronary artery from the pulmonary artery. In this article, we review the imaging, particularly computed tomography and magnetic resonance imaging of unusual fistulas and connections involving the cardiovascular system, particularly the coronary arteries and the aorta.

    Temporary epicardial pacing wires during open-heart surgery are routinely used both for diagnostic and treatment purposes. In complicated cases where patients are unstable or the wires are difficult to remove, the pacing wires are cut at the skin level and allowed to retract by themselves. This procedure rarely causes complications. However, there have been cases reporting that retained pacing wires are linked to the formation of sterno-bronchial fistulae, which may present a while after the date of operation and are usually infected. This review aims to study the cases presenting sterno-bronchial fistulae due to retained epicardial pacing wires and to highlight the important factors associated with these. It is important to note these complications, as fistulae may cause a variety of problems to the patient if undiagnosed and left untreated. With the aid of scans such as fistulography, fistulae can be identified and treated and will improve the patients’ health dramatically. PMID:27716700

    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.

    Xanthogranulomatous pyelonephritis (XGP) is a rare histological subset of pyelonephritis characterized by being a chronic destructive granulomatous inflammation of the renal parenchyma. XGP is classified according to the extent of disease into two entities: within the renal cortex (focal or segmental XGP) or diffuse spread with pelvic communication (diffuse XGP). Although rare, XGP can have fatal complications including perinephric, psoas abscess, nephro-cutaneous fistula and reno-colic fistula. Only few studies have reported XGP complicated with psaos abcess and reno-colic fistula. Our aim is to add to the literature and share our experience with a case of extensive XGP eroding into the psoas muscle and ascending colon leading to severe sepsis that was successfully managed. We report a 56-year-old woman who was found to have XGP complicated by psoas abscess and reno-colic fistula managed by antibiotics, nephrostomy, and subsequent nephrectomy and partial colectomy.

    Xanthogranulomatous pyelonephritis (XGP) is a rare histological subset of pyelonephritis characterized by being a chronic destructive granulomatous inflammation of the renal parenchyma. XGP is classified according to the extent of disease into two entities: within the renal cortex (focal or segmental XGP) or diffuse spread with pelvic communication (diffuse XGP). Although rare, XGP can have fatal complications including perinephric, psoas abscess, nephro-cutaneous fistula and reno-colic fistula. Only few studies have reported XGP complicated with psaos abcess and reno-colic fistula. Our aim is to add to the literature and share our experience with a case of extensive XGP eroding into the psoas muscle and ascending colon leading to severe sepsis that was successfully managed. We report a 56-year-old woman who was found to have XGP complicated by psoas abscess and reno-colic fistula managed by antibiotics, nephrostomy, and subsequent nephrectomy and partial colectomy.

    Thoracic endovascular aortic repair for thoracic aortic aneurysms is an accepted alternative to open surgery, especially in patients with significant comorbidities. The procedure itself has a low risk of complications and fistulas to surrounding organs are rarely reported. An 86-year-old patient was admitted to our hospital with gastro intestinal (GI) bleeding and a suspected aortoesophageal fistula. Eight months prior, the patient had undergone a stent graft repair of a mycotic thoracic aneurysm. Computerized tomography angiography and upper GI endoscopy confirmed an aortoesophageal fistula, which was treated by esophageal stenting. With early recognition, esophageal stenting may have a role in the initial emergency control of bleeding from and palliation of aortoesophageal fistula. PMID:27574612

  18. Severe hematuria after transurethral electrocoagulation in a patient with an arteriovesical fistula

    PubMed Central

    2013-01-01

    Background Arteriovesical fistulas are extremely rare. Only eleven cases were previously reported in the literature. They can occur iatrogenically, traumatically or spontaneously. Case presentation 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. Conclusions 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. PMID:24289138

    In patients with fistulas that impair function (e.g., feeding, resonance, intelligibility), obturators are used to improve feeding and reduce nasal air emission by occluding the abnormal opening between the oral and nasal cavities. This report describes a novel method for occluding an anterior palatal fistula in patients with cleft palates. The new design for a fixed obturator is based on the Nance appliance, which was originally used as a space maintainer, but has been redesigned for closing an anterior palatal fistula in a patient with cleft lip and palate. The Nance obturator may be used when the surgical closure of the fistula is not feasible and a removable device is not successful. As it is a fixed device, it does not require remaking with maxillary growth. The new design may also function as a fixed space maintainer to preserve molar anchorage and maxillary transverse width.

    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.

    Obstetric fistula is a devastating condition that results from prolonged or unassisted labor. It produces debilitating physical and emotional consequences caused by constant leaking of urine and/or feces. Because high-quality medical care is available throughout the developed world, unrepaired obstetric fistulae are virtually nonexistent in developed nations. However, the condition is rampant in many developing countries, including Niger, a nation in West Africa. This article explains what obstetric fistula is, why it is such a problem, and what nurses and other health care professionals can do to help improve the situation worldwide. It also tells the story of one nurse who went on a volunteer mission to treat obstetric fistulae in Niger, where she met a courtyard full of women she will never forget.

    The present article describes two cases of bronchopleural fistula (BPF) occurring after radiofrequency ablation of lung tumors. Both procedures were carried out using expandable multitined electrodes, with no coagulation of the needle track. After both ablations, ground-glass opacities encompassed the nodules and abutted the visceral pleura. The first patient had a delayed pneumothorax, and the second had a recurrent pneumothorax. Both cases of BPF were diagnosed on follow-up computed tomography chest scans (i.e., visibility of a distinct channel between the lung or a peripheral bronchus and the pleura) and were successfully treated with chest tubes alone. Our goal is to highlight the fact that BPF can occur without needle-track coagulation and to suggest that minimally invasive treatment is sufficient to cure BPFs of this specific origin.

    Orocutaneous fistula (OCF) (of dental origin) is an uncommon but well-described condition in the literature. These are often misdiagnosed by physicians and dentists. Careful selection of investigating modality is important in case of diagnostically challenging cases. A 19-year-old female came with a complaint of a lesion on the chin reported with h/o trauma with the impact on chin presented as diagnostic dilemma because of unusual case history and clinical examination. Commonly used radiographic investigations like IOPA and orthopantomograph did not resolve the dilemma whereas advanced imaging modality like CT scan, 3D volume imaging, and contrast enhanced CT played an important role in the diagnosis of OCF and selecting the treatment plan.

We report three additional cases that share peculiar clinical characteristics, pointing to diagnostic clues. All three cases presented as erythematous nodules developing distally to a proximal arteriovenous fistula (AVF). This presentation was identical to that of two published cases. A survey of all Belgian haemodialysis units during the period 2007–11 yields an estimated incidence of ∼0.9/10 000 patient-years. Although the source of M. chelonae remains unclear, this specific clinical presentation should be added to the listing of potential complications of an AVF and should be recognized, as it is fully treatable if diagnosed by culture and tissue biopsy.

    Perineurial cysts usually affect the lumbosacral spinal nerve roots, but sometimes they can erode the sacrum and reach the retroperitoneal space. In such cases misdiagnosis can lead to an improper treatment and cause serious complications. A presacral mass was diagnosed in a young woman during routine ultrasound investigation, and an exploratory laparotomy was performed. A large, fluid-containing cyst was found and marsupialized into the pelvis. After operation the patient experienced headache, vomiting and VI cranial nerve palsy whenever she stood up. By radiculography a iatrogenic spinopelvic cerebro-spinal fluid fistula was diagnosed, which required further surgery to be repaired. The presence of a giant perineurial cyst in the pelvis in unusual but must be considered in the differential diagnosis of presacral masses; the exceptionally rare case reported in this paper is exemplar of the harmful complications that an incautious procedure can determine.

    Introduction Adenoid cystic carcinoma (ACC) is one of the most frequent malignant salivary gland tumors, which commonly affects the minor salivary glands of the mouth and is rare in the nose and paranasal sinuses. In the maxillary sinus, ACC can mimic inflammatory diseases and has a poor prognosis. Objective To report a case of a 50-year-old man with ACC of the maxillary sinus whose clinical findings in the alveolar ridge mimicked an oroantral fistula. Case Report An excisional biopsy was performed and histopathologic analysis revealed ACC. Lung metastases and residual tumor in the maxillary sinus were detected by imaging methods. In view of the poor general health of the patient, no new surgical intervention was performed and he was only treated by radiotherapy and follow-up. Conclusion Although rare in the maxillary sinus, ACC should be included in the differential diagnosis of lesions affecting this site. PMID:25992095

Conservative management failed to contain the hemorrhage. Hence the fistula was occluded by coil embolization through the renal vein. This endovascular approach enabled rapid and effective stoppage of the venous bleed.There was no recurrence of the bleed or any pertinent complication at 3-month follow-up.

    2016-01-01

    Background Autologous arteriovenous (AV) fistulas are the first choice for vascular access but have a high risk of non-maturation due to insufficient vessel adaptation, a process dependent on nitric oxide (NO)-signaling. Chronic kidney disease (CKD) is associated with oxidative stress that can disturb NO-signaling. Here, we evaluated the influence of CKD on AV fistula maturation and NO-signaling. Methods CKD was established in rats by a 5/6th nephrectomy and after 6 weeks, an AV fistula was created between the carotid artery and jugular vein, which was followed up at 3 weeks with ultrasound and flow assessments. Vessel wall histology was assessed afterwards and vasoreactivity of carotid arteries was studied in a wire myograph. The soluble guanylate cyclase (sGC) activator BAY 60–2770 was administered daily to CKD animals for 3 weeks to enhance fistula maturation. Results CKD animals showed lower flow rates, smaller fistula diameters and increased oxidative stress levels in the vessel wall. Endothelium-dependent relaxation was comparable but vasorelaxation after sodium nitroprusside was diminished in CKD vessels, indicating NO resistance of the NO-receptor sGC. This was confirmed by stimulation with BAY 60–2770 resulting in increased vasorelaxation in CKD vessels. Oral administration of BAY 60–2770 to CKD animals induced larger fistula diameters, however; flow was not significantly different from vehicle-treated CKD animals. Conclusions CKD induces oxidative stress resulting in NO resistance that can hamper AV fistula maturation. sGC activators like BAY 60–2770 could offer therapeutic potential to increase AV fistula maturation.

    Background Coronary artery fistula (CAF) is a rare anomaly. Transcatheter CAF closure has been introduced using various materials, but only few data are available on the Guglielmi detachable coil (GDC). The advantage of using GDC for transcatheter CAF closure is more controllable, therefore much safer when compared to other coils. This report is about our experience in transcatheter closure of CAF using fibered GDC in our hospital. Methods & Results From 2002 to 2007, there were 10 patients with CAFs (age range: 28 to 56 year-old, 7 males) who underwent transcatheter CAF closure. There were a total of 19 CAFs which originated from right coronary (n = 5), left circumflex (n = 3), left anterior descending artery (n = 10) and left main trunk (n = 1). Median number of coil deployment for each fistula was 3 (range: 1 to 6). The pulmonary artery was the most common site of the distal communication of CAFs (n = 14), followed by right atrium (n = 3), left atrium (n = 1) and left ventricle (n = 1). Immediate coronary angiography after GDC deployment revealed no residual shunt in 12 (63.2%) CAFs, significant reduction of the flow in 5 (26.3%), while 2 (10.5%) could not be closed due to small size. Nine (90%) patients underwent a repeated angiography within 3 to 8 months. Among 12 CAFs that were occluded immediately post-deployment, there were 2 CAFs with insignificant residual flow. Among 6 CAFs with significantly decreased flow immediately post-deployment, 2 were occluded totally in the follow-up angiography. In total, 12 (70.5%) CAFs were occluded completely and 5 (29.5%) CAFs still had insignificant residual flow, which did not need any additional coil deployment. During a mean follow up of 4.3 ± 0.7 year, all patients remained symptom and complication free. Conclusions The fibered GDC is a safe and effective method for percutaneous closure of the CAFs.

    Readmission rates after pancreaticoduodenectomy (PD) are among the highest of any surgical procedure. The purpose of this study was to identify those factors present at discharge that may predict readmission after PD. All patients undergoing PD between 2010 and 2015 at a very high (>35 PD/year) volume center were entered into a prospective database. Twenty factors present at discharge from index admission identified on univariate analysis were subjected to multivariate analysis to identify those independently predictive of 30-day hospital readmission. A total of 220 patients underwent PD during the study period, 88 per cent of which had cancer. Mean age was 64.4 ± 11.7 years with slight male preponderance (54.5%) and significant African American representation (33.2%). Surgical complications occurred in 67.3 per cent of patients the most common of which included infectious/leak (30%), gastrointestinal (29%), cardiorespiratory (13%), other (13%), minor complications (7%), multi system failure (5%), and new onset diabetes (3%). The 30-day readmission rate was 27.3 per cent and was due to infection (89%), failure to thrive (32%), nausea/vomiting (15%), or other (15%). On multivariate analysis, presence of pancreatic leak/fistula at discharge was the only significant predictor of readmission, present in 62.5 per cent of all readmitted patients (P = 0.001). Comorbidities, length of stay, insurance status, obesity, smoking, and discharge to a care venue other than home did not predict readmission. Patients manifesting pancreatic fistula after PD are at high risk for hospital readmission. Enhanced scrutiny regarding suitability for discharge should be exercised in these patients and measures taken to minimize readmission whenever possible. PMID:27657584

    We retrospectively evaluated the usefulness of both arterial and venous access with the pull-through technique in endovascular treatment of totally occluded Brescia-Cimino fistulas. We treated 26 patients (17 men, 9 women; age range 43-82 years, mean age 66 years) with occluded Brescia-Cimino fistulas. First, the occluded segment was traversed from the antegrade brachial arterial access using a microcatheter-guidewire system. Second, the vein was retrogradely punctured after confirmation of all diseased segments, and a 0.014- or 0.016-inch guidewire was pulled through the venous access when the occluded segment was long. All interventions including thrombolysis, thromboaspiration, angioplasty, and stent placement were performed via the venous access. The occlusion was successfully crossed via the brachial arterial access in 23 patients (88%). In 2 patients it was done from the venous approach. In the remaining patient it was not possible to traverse the occluded segment. The pull-through technique was successful in all 19 attempts. Clinical success was achieved in 96%, the primary patency rates at 6, 12, and 18 months were 83%, 78%, and 69%, the primary assisted patency rates were 92%, 92%, and 72%, and the secondary patency rates were 92%, 92%, and 92%, respectively. Minor complications in 5 patients included venous perforation in 2 (8%), venous rupture in 1 (4%), and regional hematoma in 2 (8%). Our study suggests that endovascular treatments with both arterial and venous access using the pull-through technique are highly effective in restoring function in totally occluded Brescia-Cimino fistulas.

    Percutaneous nephrolithotomy (PCNL) is the first-line treatment for kidney stones. Colon perforation is a rare, but dangerous, complication. Colonic perforation might be very serious if it is not found early. After an unsuccessful extracorporeal shockwave lithotripsy, a 45-year-old female underwent a left-sided PCNL for two 1-cm kidney stones in the left kidney upper pole calyx. During dilatation, a colon perforation was suspected. The procedure was finished by inserting a 14Fr re-entry catheter into the colon. On postoperative day 5, a fluoroscopy was performed by injecting contrast dye through the re-entry catheter, which showed a fistula formation between skin and colon. The catheter was removed completely. A 16Fr external drainage catheter was inserted over the guide-wire through the fistula tract. The fistula was closed by introducing prepared absorbable hemostatic gelatin powder (Spongostan) particles into the fistula tract through the catheter. Fistula tracks can be closed early by injecting absorbable Spongostan particles into the colonic fistula tract, thereby reducing inpatient time and increasing patient comfort.

    Rectal perforations due to glycerin enemas (GE) typically occur when the patient is in a seated or lordotic standing position. Once the perforation occurs and peritonitis results, death is usually inevitable. We describe two cases of rectal perforation and fistula caused by a GE. An 88-year-old woman presented with a large rectal perforation and a fistula just after receiving a GE. Her case was further complicated by an abscess in the right rectal wall. The second patient was a 78-year-old woman who suffered from a rectovesical fistula after a GE. In both cases, we performed direct endoscopic abscess lavage with a saline solution and closed the fistula using an over-the-scope-clip (OTSC) procedure. These procedures resulted in dramatic improvement in both patients. Direct endoscopic lavage and OTSC closure are very useful for pararectal abscess lavage and fistula closure, respectively, in elderly patients who are in poor general condition. Our two cases are the first reports of the successful endoscopic closure of fistulae using double OTSCs after endoscopic lavage of the debris and an abscess of the rectum secondary to a GE.

    2014-06-01

    We present a 47-year-old female patient with spontaneous carotid-cavernous fistula without comorbidities. The symptoms of a carotid-cavernous fistula may be confused with other pathology in the region of the orbit and cavernous sinus such as cavernous sinus thrombosis. Carotid-cavernous fistulas most commonly result from direct injury to the internal carotid artery, as with skull base or surgical trauma, but it can also result from weakness in the arterial wall, as with an aneurysm. Because of the high flow of the internal carotid artery, carotid-cavernous fistulas typically present with rapidly progressive symptoms. The case study presented demonstrates the usefulness of radiologic studies in distinguishing between these similarly presenting disease processes. Clinically, cavernous sinus thrombosis generally presents bilaterally and carotid-cavernous fistula presents unilaterally; however, there are a number of exceptions in the literature. The use of a variety of radiologic and angiographic studies will help differentiate between these pathologies. On magnetic resonance imaging, both pathologies can appear as an enlargement of cavernous sinus. Magnetic resonance angiography sequence can reveal aneurysms communicating with the cavernous sinus, and magnetic resonance venography will define thrombosis within the cavernous sinus. Differentiating between cavernous sinus thrombosis and carotid-cavernous fistula can be clinically difficult, and a team approach including emergency physicians, neurosurgeons, ophthalmologists, and otolaryngologists will be called upon to assist in diagnosis. Prompt diagnosis and management can allow for potentially vision and lifesaving interventions. PMID:24656959

    Background The aim of this study was to compare the outcomes of the management of perianal fistulas in Crohn disease between infliximab, surgery or a combination of surgery and infliximab. Methods We prospectively subdivided 35 consecutive patients with Crohn disease with complex perianal fistulas into 3 groups: 11 patients received infliximab (5 mg/kg intravenously at 0, 2 and 6 wk; group A), 10 underwent surgery (group B) and 14 received a combination of surgery and postoperative infliximab (group C). We evaluated the rate and time of healing of perianal fistulas, the rate of recurrences and time to relapse at a median follow-up of 18.8 (standard deviation [SD] 10.8, range 8–38) months. Results The time to healing of fistulas was significantly shorter among patients who received surgery and infliximab than among those who received surgery alone (p < 0.05) and was close to statistically shorter among those who received both treatments than among those who received infliximab alone (p = 0.06). Patients who received surgery and infliximab had a significantly longer mean time to relapse (p < 0.05) than those who received infliximab (mean 2.6 [SD 0.7] mo) or surgery alone (mean 3.6 [SD 0.5] mo). Conclusion We found better outcomes among patients who received a combination of surgery and infliximab therapy. These patients experienced a short time to healing of fistulas and significantly longer mean time to relapse of complex fistulas. PMID:20858373

    Benign colonic strictures and fistulas are a growing problem presenting most commonly after bowel resection. Standard treatment is with endoscopic bougies or, more usually, balloon dilation. When these approaches are not successful, other solutions are available and different endoscopic and surgical approaches have been used to treat fistulas. We present an additional option--biodegradable stents--for the treatment of colonic strictures and fistulas that have proven refractory to other endoscopic interventions. We analyzed the results from 10 patients with either a postsurgical colorectal stricture (n =7) or rectocutaneous fistula (n =3) treated with the biodegradable SX-ELLA esophageal stent (covered or uncovered). Stents were successfully placed in nine patients, although early migration subsequently occurred in one. Placement was impossible in one patient due to deformity of the area and the fact that the stricture was approximately 30cm from the anus. The fistulas were successfully closed in all patients, although symptoms reappeared in one patient. In the six patients who received stents for strictures, symptoms resolved in five; in the remaining patient, the stent migrated shortly after the endoscopy. Treatment of colonic strictures and rectocutaneous fistulas with biodegradable stents is an effective alternative in the short-to-medium term. The stent does not have to be removed and is subject to very few complications. The drawbacks of this approach are the need to repeat the procedure in some patients and the lack of published series on efficacy.

    Vascular access dysfunction contributes to the mortality of patients undergoing chronic hemodialysis. The present study analyzed the changes that evolve in a femoral arteriovenous fistula in the rat. The venous segment of this model exhibited, at 1 week, activation of pro-inflammatory transcription factors and up-regulation of pro-inflammatory, proliferative, procoagulant, and profibrotic genes; and at 4 weeks, the venous segment displayed neointimal hyperplasia, smooth muscle proliferation, and thrombus formation. These changes were accompanied by endothelial (e) nitric oxide synthase (NOS) and inducible (i) NOS up-regulation. The administration of NG-nitro-L-arginine methyl ester, an inhibitor of NOS activity, increased venous neointimal hyperplasia and pro-inflammatory gene expression (monocyte chemoattractant protein−1 and cytokine-induced neutrophil chemoattractant-1), increased systolic blood pressure, and decreased blood flow through the fistula. In another hypertensive model, the rat subtotal nephrectomy model, venous neointimal hyperplasia in the arteriovenous fistula was also exacerbated. We conclude that this arteriovenous fistula model recapitulates the salient features observed in dysfunctional, hemodialysis arteriovenous fistulas, and that venous neointimal hyperplasia is exacerbated when this model is superimposed in two different models of systemic hypertension. Since the uremic milieu contains increased amounts of asymmetric dimethylarginine, we speculate that such accumulation of this endogenous inhibitor of NOS, by virtue of its pressor or nitric oxide-depleting effects, or a combination thereof, may contribute to the limited longevity of arteriovenous fistulas used for hemodialysis.

    Recto-urinary fistula results as a complication following trauma to the perinium and pelvis. These fistulas are difficult to treat and have a high recurrence rate due to the difficult surgical approach in repairing them. Both the transabdominal or transperineal approaches used in repairing these fistulas are difficult and provide only limited exposure to the fistula being repaired. In the case report, we present a patient with complex recto-urinary fistula due to trauma to the pelvis 20 years previously. In this patient we used the transphincteric York Mason approach to directly approach the fistula, followed by construction of a tube flap connecting the bladder and the urethra. The technique is simple, easy and the outcome has been excellent after 4 years of follow-up. PMID:11560228

    The epithelial coating of the rectal pouch and fistula was studied morphologically in 33 newborn piglets with high and low forms of anal atresia and was found to be similar to the epithelial coating of the anal canal in normal piglets: the typical epithelium of the rectum changed its character into transitional epithelium at the region of the internal sphincter which surrounded the fistulae in all animals. In the caudal part of the fistula the transitional epithelium was followed by squamous epithelium. Only in male piglets with deformities and recto-urethral fistulae no squamous epithelium was found. In these cases transitional epithelium covered all parts of the fistula and the region of the internal sphincter. Anal glands were found in all animals, with or without anorectal malformations. They always invaded the internal sphincter. According to our morphological studies the fistula in anorectal malformations represents an ectopic anal canal.

    Transcatheter closure of coronary artery fistulas can be executed successfully in infants and children with few serious procedural complications. Indications for and long-term outcomes of closure of coronary artery fistulas remain poorly defined. Registries may offer the best opportunity for advancing our knowledge about uncommon interventions such as coil or device closure of coronary artery fistulas, but to do so, they must include sufficient data and evaluate factors potentially associated with salutary or adverse outcome.

    Urethrocavernous fistula is a rare complication of penile prosthesis. Literature lacks any materials regarding this complication's treatment. We report our experience with a 66-year-old man who developed urethrocavernous fistula after penile prosthesis implant. Our technique involves the careful closure of urethral and corpus cavernosum defects with application of TachoSil® above the sutures. After the salvage procedure, no recurrence of fistula occurred and patient was able to have sexual intercourse. We believe that our technique may be successfully used in case of urethrocavernous fistula after penile prosthesis implant. PMID:26925286

    AIM To analyze the risk factors for pancreatic fistula after pancreaticoduodenectomy. METHODS We conducted a retrospective analysis of 539 successive cases of pancreaticoduodenectomy performed at our hospital from March 2012 to October 2015. Pancreatic fistula was diagnosed in strict accordance with the definition of pancreatic fistula from the International Study Group on Pancreatic Fistula. The risk factors for pancreatic fistula were analyzed by univariate analysis and multivariate logistic regression analysis. RESULTS A total of 269 (49.9%) cases of pancreatic fistula occurred after pancreaticoduodenectomy, including 71 (13.17%) cases of grade A pancreatic fistula, 178 (33.02%) cases of grade B, and 20 (3.71%) cases of grade C. Univariate analysis showed no significant correlation between postoperative pancreatic fistula (POPF) and the following factors: age, hypertension, alcohol consumption, smoking, history of upper abdominal surgery, preoperative jaundice management, preoperative bilirubin, preoperative albumin, pancreatic duct drainage, intraoperative blood loss, operative time, intraoperative blood transfusion, Braun anastomosis, and pancreaticoduodenectomy (with or without pylorus preservation).

    Objectives Obstetric fistula is a maternal injury that causes uncontrollable leaking of urine or stool, and most women who develop it live in poverty in low-income countries. Obstetric fistula is associated with high rates of stigma and psychological morbidity, but there is uncertainty about the impact of surgical treatment on psychological outcomes. The objective of this exploratory study was to examine changes in psychological symptoms following surgical fistula repair, discharge and reintegration home. Methods Women admitted for surgical repair of obstetric fistula were recruited from a Tanzanian hospital serving a rural catchment area. Psychological symptoms and social functioning were assessed prior to surgery. Approximately 3 months after discharge, a data collector visited the patients' homes to repeat psychosocial measures and assess self-reported incontinence. Baseline to follow-up differences were measured with paired t tests controlling for multiple comparisons. Associations between psychological outcomes and leaking were assessed with t tests and Pearson correlations. Results Participants (N = 28) had been living with fistula for an average of 11 years. Baseline psychological distress was high, and decreased significantly at follow-up. Participants who self-reported continued incontinence at follow-up endorsed significantly higher PTSD and depression symptoms than those who reported being cured, and severity of leaking was associated with psychological distress. Conclusions Fistula patients experience improvements in mental health at 3 months after discharge, but these improvements are curtailed when women experience residual leaking. Given the rate of stress incontinence following surgery, it is important to prepare fistula patients for the possibility of incomplete cure and help them develop appropriate coping strategies.

    ABSTRACT Background: The anorectal anomalies consist in a complex group of birth defects. Laparoscopic-assisted anorectoplasty improved visualization of the rectal fistula and the ability to place the pull-through segment within the elevator muscle complex with minimal dissection. There is no consensus on how the fistula should be managed. Aim: To evaluate the laparoscopic-assisted anorectoplasty and the treatment of the rectal urinary fistula by a bipolar sealing device. Method: It was performed according to the original description by Georgeson1. Was used 10 mm infraumbilical access portal for 30º optics. The pneumoperitoneum was established with pressure 8-10 cm H2O. Two additional trocars of 5 mm were placed on the right and left of the umbilicus. The dissection started on peritoneal reflection using Ligasure(r). With the reduction in the diameter of the distal rectum was identified the fistula to the urinary tract. The location of the new anus was defined by the location of the external anal sphincter muscle complex, using electro muscle stimulator externally. Finally, it was made an anastomosis between the rectum and the new location of the anus. A Foley urethral probe was left for seven days. Results: Seven males were operated, six with rectoprostatic and one with rectovesical fistula. The follow-up period ranged from one to four years. The last two patients operated underwent bipolar sealing of the fistula between the rectum and urethra without sutures or surgical ligation. No evidence of urethral leaks was identified. Conclusion: There are benefits of the laparoscopic-assisted anorectoplasty for the treatment of anorectal anomaly. The use of a bipolar energy source that seals the rectal urinary fistula has provided a significant decrease in the operating time and made the procedure be more elegant. PMID:27759786

    Fistula is a representative devastating complication in Crohn's patients due to refractory to conventional therapy and high recurrence. In our phase I clinical trial, adipose tissue-derived stem cells (ASCs) demonstrated their safety and therapeutic potential for healing fistulae associated with Crohn's disease. This study was carried out to evaluate the efficacy and safety of ASCs in patients with Crohn's fistulae. In this phase II study, forty-three patients were treated with ASCs. The amount of ASCs was proportioned to fistula size and fistula tract was filled with ASCs in combination with fibrin glue after intralesional injection of ASCs. Patients without complete closure of fistula at 8 weeks received a second injection of ASCs containing 1.5 times more cells than the first injection. Fistula healing at week 8 after final dose injection and its sustainability for 1-year were evaluated. Healing was defined as a complete closure of external opening without any sign of drainage and inflammation. A modified per-protocol analysis showed that complete fistula healing was observed in 27/33 patients (82%) by 8 weeks after ASC injection. Of 27 patients with fistula healing, 26 patients completed additional observation study for 1-year and 23 patients (88%) sustained complete closure. There were no adverse events related to ASC administration. ASC treatment for patients with Crohn's fistulae was well tolerated, with a favorable therapeutic outcome. Furthermore, complete closure was well sustained. These results strongly suggest that autologous ASC could be a novel treatment option for the Crohn's fistula with high-risk of recurrence.

    AIM: To check the efficacy of the PERFACT procedure in highly complex fistula-in-ano. METHODS: The PERFACT procedure (proximal superficial cauterization, emptying regularly fistula tracts and curettage of tracts) entails two steps: superficial cauterization of mucosa at and around the internal opening and keeping all the tracts clean. The principle is to permanently close the internal opening by granulation tissue. This is achieved by superficial electrocauterization at and around the internal opening and subsequently allowing the wound to heal by secondary intention. Along with this, all the tracts are curetted and it is ensured that they remain empty and clean in the postoperative period until they heal completely. The latter step also facilitates the closure of the internal opening by preventing collected fluid in the tracts from entering the internal opening and thus not letting it close. Objective incontinence scoring was done preoperatively and 3 mo after the operation. RESULTS: Fifty-one patients with complex fistula-in-ano were prospectively enrolled. The median follow-up was 9 mo (5-14 mo). The mean age was 42.7 ± 11.3 years. Male:female ratio was 43:8. Fistula was recurrent in 76.5% (39/51), horseshoe in 50.1% (26/51), had multiple tracts in 52.9% (27/51), had an associated abscess in 41.2% (21/51), was anterior in 33.3% (17/51), the internal opening was not found in 15.7% (8/51) and 9.8% (5/51) of fistulas had a supralevator extension. Seven patients were excluded (5 lost to follow up, 2 with tuberculosis leading to/associated with fistula-in-ano). The success rate was 79.5% (35/44) and the recurrence rate was 20.5% (9/44). Out of these recurrences, three underwent reoperation (2 PERFACT procedure, 1 fistulotomy) and all three were successful. Thus, the overall success rate was 86.4%. The only complication was a non-healing tract in 9.1% (4/44) of patients. There was no significant change in objective incontinence scores three months after the operation

    The aim of this study was to examine the clinical technique of using an intraoral camera to monitor the size of residual oronasal fistulas in cleft lip-cleft palate patients, to assess its repeatability on study casts and patients, and to compare its use with other methods. Seventeen plaster study casts of cleft palate patients with oronasal fistulas obtained from a 5-year series of 160 patients were used. For the clinical study, 13 patients presenting in a clinic prospectively over a 1-year period were imaged twice by the camera. The area of each fistula on each study cast was measured in the laboratory first using a previously described graph paper and caliper technique and second with the intraoral camera. Images were imported into a computer and subjected to image enhancement and area measurement. The camera was calibrated by imaging a standard periodontal probe within the fistula area. The measurements were repeated using a double-blind technique on randomly renumbered casts to assess the repeatability of measurement of the methods. The clinical images were randomly and blindly numbered and subjected to image enhancement and processing in the same way as for the study casts. Area measurements were computed. Statistical analysis of repeatability of measurement using a paired sample t test showed no significant difference between measurements, indicating a lack of systematic error. An intraclass correlation coefficient of 0.97 for the graph paper and 0.84 for the camera method showed acceptable random error between the repeated records for each of the two methods. The graph paper method remained slightly more repeatable. The mean fistula area of the study casts between each method was not statistically different when compared with a paired samples t test (p = 0.08). The methods were compared using the limits of agreement technique, which showed clinically acceptable repeatability. The clinical study of repeated measures showed no systematic differences when

    Introduction: Spontaneous nephrocutaneous fistula is a rare manifestation of renal disease that can occur due to various etiologies, such as renal calculus, chronic pyelonephritis, stricture of the ureteropelvic junction, and renal tuberculosis (TB). An autonephrectomy with a nephrocutaneous fistula due to renal tuberculosis can be diagnosed quite late if it is not suspected. Case Presentation: We report a case of a spontaneous nephrocutaneous fistula with tuberculous autonephrectomy. A 40-year-old white male with recurrent flank pain and intermittent purulent drainage from his right flank region for the previous 14 years was admitted to our outpatient clinic. Fistulography and computerized tomography demonstrated a 51 × 60 mm area with a soft-tissue appearance that implied autonephrectomy of the right kidney, and a fistula tract with a 9 mm diameter between the skin and the retroperitoneal space. The patient was successfully treated with nephroureterectomy and excision of the fistulous tract, followed by antituberculous treatment. The pathological examination of the surgical specimen revealed chronic atrophic pyelonephritis, calcifications, and necrotizing granulomatous inflammation suggestive of TB. Conclusions: Urogenital TB is difficult to diagnose due to the lack of specific symptoms and signs. In the case of a nonfunctioning kidney without an obvious cause and a chronic spontaneous nephrocutaneous fistula, the possibility of associated renal TB should be kept in mind, especially in immunocompromised patients or in places where TB is a common health problem.

  4. Effects of wall distensibility in hemodynamic simulations of an arteriovenous fistula.

    PubMed

    2014-06-01

    Arteriovenous fistulae are created surgically to provide adequate access for dialysis patients suffering from end-stage renal disease. It has long been hypothesized that the rapid blood vessel remodeling occurring after fistula creation is in part a process to restore the mechanical stresses to some preferred level, i.e., mechanical homeostasis. The current study presents fluid-structure interaction (FSI) simulations of a patient-specific model of a mature arteriovenous fistula reconstructed from 3D ultrasound scans. The FSI results are compared with previously published data of the same model but with rigid walls. Ultrasound-derived wall motion measurements are also used to validate the FSI simulations of the wall motion. Very large time-averaged shear stresses, 10-15 Pa, are calculated at the fistula anastomosis in the FSI simulations, values which are much larger than what is typically thought to be the normal homeostatic shear stress in the peripheral vasculature. Although this result is systematically lower by as much as 50% compared to the analogous rigid-walled simulations, the inclusion of distensible vessel walls in hemodynamic simulations does not reduce the high anastomotic shear stresses to "normal" values. Therefore, rigid-walled analyses may be acceptable for identifying high shear regions of arteriovenous fistulae. PMID:24037281

    Obstetric fistula is a debilitating childbirth injury that has been associated with high rates of psychological distress. Global efforts have helped to link women to surgical repair, but thus far no evidence-based interventions exist to address the psychological needs of these women during the hospital stay. In this paper, we describe the development of a psychological intervention for women in Tanzania who are receiving surgical care for an obstetric fistula. The intervention was developed based on theories of cognitive behavioral therapy and coping models. Content and delivery were informed by qualitative data collection with a range of stakeholders including women with fistula, and input from a study advisory board. The resulting intervention was six individual sessions, delivered by a trained community health nurse. The session topics were: 1) recounting the fistula story; 2) creating a new story about the fistula; 3) loss, grief and shame; 4) specific strategies for coping; 5) social relationships; and 6) planning for the future. A trial run of the intervention revealed that the intervention could be delivered with fidelity and was acceptable to patients. A future randomized control trial will evaluate the efficacy of this intervention to address the mental health symptoms of this population. PMID:25710896

    Palatal fistula following cleft palate repair, is one of the considerable complications and remains a challenging problem to the surgeons. The reported recurrence rate of the fistula is between 33% to 37%. Due to fibrosis and poor vascularity of adjacent tissues, high recurrence rates are typical. Closure of palatal fistulas can be achieved by different surgical techniques like local, regional and distant flaps, local turnover flaps, pedicled flaps from oral mucosa, buccal fat pad flaps, inter-positional cartilage grafts can be utilized for management of small fistulas. For larger fistualas, tongue flaps, temporalis muscle flaps, musculomucosal flaps, nasal septal flaps and free flaps can be used. These procedures are often cumbersome and leave a raw nasal or oral surface, which may increase the incidence of postoperative problems or some flaps can be bulky and may require a second-stage procedure. Different synthetic materials such as alloderm, Poly-D and L-Lactic Acid or “PdLLA” and collagen membrane are used in multilayer repair represented by the nasal mucosa, the inter-positional graft and oral mucosa. These interpositional grafts provide a scaffold for in growth of tissues, revascularization and mucosal epithelialization. We present a case of closure of an oronasal fistula, using resorbable collagen membrane in three layered repair to avoid recurrence. PMID:27135018

    Arteriovenous fistulae are created surgically to provide adequate access for dialysis patients suffering from end-stage renal disease. It has long been hypothesized that the rapid blood vessel remodeling occurring after fistula creation is in part a process to restore the mechanical stresses to some preferred level, i.e. mechanical homeostasis. The current study presents fluid-structure interaction (FSI) simulations of a patient-specific model of a mature arteriovenous fistula reconstructed from 3D ultrasound scans. The FSI results are compared with previously published data of the same model but with rigid walls. Ultrasound-derived wall motion measurements are also used to validate the FSI simulations of the wall motion. Very large time-averaged shear stresses, 10–15 Pa, are calculated at the fistula anastomosis in the FSI simulations, values which are much larger than what is typically thought to be the normal homeostatic shear stress in the peripheral vasculature. Although this result is systematically lower by as much as 50% compared to the analogous rigid-walled simulations, the inclusion of distensible vessel walls in hemodynamic simulations does not reduce the high anastomotic shear stresses to “normal” values. Therefore, rigid-walled analyses may be acceptable for identifying high shear regions of arteriovenous fistulae. PMID:24037281

    Postoperative pancreatic fistula is still a major complication after pancreatic surgery, despite improvements of surgical technique and perioperative management. We sought to systematically review and critically access the conduct and reporting of methods used to develop risk prediction models for predicting postoperative pancreatic fistula. We conducted a systematic search of PubMed and EMBASE databases to identify articles published before January 1, 2015, which described the development of models to predict the risk of postoperative pancreatic fistula. We extracted information of developing a prediction model including study design, sample size and number of events, definition of postoperative pancreatic fistula, risk predictor selection, missing data, model-building strategies, and model performance. Seven studies of developing seven risk prediction models were included. In three studies (42 %), the number of events per variable was less than 10. The number of candidate risk predictors ranged from 9 to 32. Five studies (71 %) reported using univariate screening, which was not recommended in building a multivariate model, to reduce the number of risk predictors. Six risk prediction models (86 %) were developed by categorizing all continuous risk predictors. The treatment and handling of missing data were not mentioned in all studies. We found use of inappropriate methods that could endanger the development of model, including univariate pre-screening of variables, categorization of continuous risk predictors, and model validation. The use of inappropriate methods affects the reliability and the accuracy of the probability estimates of predicting postoperative pancreatic fistula.

    A prospective non-randomised study fibrin sealant injection to manage patients with fistula-in-ano, with magnetic resonance imaging (MRI) monitoring, was performed during the period 5/6/1999 to 28/2/2000. The aim was to determine whether a fibrin sealant could be used as a treatment modality for anorectal fistula and the usefulness of MRI perineum to monitor the disease activity. Ten patients were included in the study. Mean age was 47 years (range 7 months to 70 years). Male: female ratio was 9:1. Mean follow-up duration was 26.4 weeks. The overall success rate was 60%. The success rate of different fistula types were different (60%, 0%, 100% for intersphincteric, transphincteric, subcutaneous, respectively). Variable decrease in signal on STIR images and contrast enhancement was noted in the patients with successful and failure of fibrin sealant injection. In conclusion, fibrin sealant injection is a useful alternative treatment in the management of fistula-in-ano. MRI is helpful in delineating the anatomy of fistula-in-ano but not a useful tool to follow-up disease activity. PMID:11878300

    Summary We report our experience with transarterial embolization of traumatic carotid-cavernous fistulae (TCCFs) by using Gugliemi detachable coil (GDC). From 2000 to 2007 at our institution, 11 patients with 12 TCCFs underwent transarterial GDC embolization because of failure to occlude fistulae by detachable balloon with preservation of the parent artery. The cause of the failure to occlude the fistula by detachable balloon was small fistula tract (n=9) and/or tortuous parent artery (n=3) or repeated balloon puncture by bony fragment (n=1). All TCCFs were successfully occluded by a single session transarterial GDC embolization. The average number of coils were eight (range, two-16) with an average length of 104 cm (range, 12-283 cm). No statistically significant procedure-related neurological complication or recurrent TCCF was observed in any of the patients. Transarterial GDC embolization is a useful method in the treatment of TCCFs, particularly in those TCCFs with small fistula tract or small CS. PMID:20557793

    Congenital coronary artery fistula is an uncommon heart anomaly involving the coronary arteries. We report here a case of a 4-year-old boy who had a coronary fistula from the right coronary artery to the right ventricle, with a coronary aneurysm. He was asymptomatic, but the calculated ratio of pulmonary blood flow to systemic blood flow was shown to be high [pulmonary flow (Qp)/systemic flow(Qs)=1.78]. The coronary angiography showed that the right coronary artery was dilated beginning at the ostium and had an aneurysm at the acute marginal portion. A large spherical aneurysm approximately 20 mm in diameter was found to have been connected with coronary fistula opening into the right ventricle. Surgical repair by closure of the fistula under direct vision, partial resection and suture closure of the aneurysm was performed. Plication of the proximal portion of the right coronary artery was not performed, and the diffusely dilated artery was left untouched. After this operation, he recovered well under anticoagulant treatment with warfarin and aspirin. Postoperative angiography was performed 17 months after the surgery to evaluate morphological changes in the coronary artery. The angiography confirmed the closure of the fistula and the regression of coronary artery dilatation.

    Esophagorespiratory fistula in adults as a result of corrosive ingestion is a rare occurrence and is a difficult problem to manage. Three young (15-19 years) patients (2F, 1M) out of 115 (incidence 2.6%) of corrosive ingestion who had tracheoesophageal fistula (TEF) were reviewed retrospectively. After initial management, enteral route of nutrition was established. Based on the extent of concomitant esophageal stricture, the fistulae were classified as: type I (short) and type II (long segment). Fistula was repaired through thoracotomy and formation of a neomembranous trachea. Esophageal stricture could be managed either short-segment resection (type I) or resection and replacement (type II). The etiology was aluminum phosphide in two and caustic soda in one. All the patients were operated beyond 9 weeks of ingestion. Tracheal defect was 5, 9 and 30 mm. Fistula could be repaired by neomembranous trachea in all the patients and defect reinforced with pleural flap in two and intercostal muscle flap in one patient. Two patients required colon interposition, while one could be managed with short-segment resection. All the patients are well at follow-up. TEF due to corrosive ingestion is a rare entity in adults. Formation of a neomembranous trachea is feasible in all patients. Management of esophageal stricture depends upon the pattern of involvement of the esophagus.

    Introduction: Spontaneous nephrocutaneous fistula is a rare manifestation of renal disease that can occur due to various etiologies, such as renal calculus, chronic pyelonephritis, stricture of the ureteropelvic junction, and renal tuberculosis (TB). An autonephrectomy with a nephrocutaneous fistula due to renal tuberculosis can be diagnosed quite late if it is not suspected. Case Presentation: We report a case of a spontaneous nephrocutaneous fistula with tuberculous autonephrectomy. A 40-year-old white male with recurrent flank pain and intermittent purulent drainage from his right flank region for the previous 14 years was admitted to our outpatient clinic. Fistulography and computerized tomography demonstrated a 51 × 60 mm area with a soft-tissue appearance that implied autonephrectomy of the right kidney, and a fistula tract with a 9 mm diameter between the skin and the retroperitoneal space. The patient was successfully treated with nephroureterectomy and excision of the fistulous tract, followed by antituberculous treatment. The pathological examination of the surgical specimen revealed chronic atrophic pyelonephritis, calcifications, and necrotizing granulomatous inflammation suggestive of TB. Conclusions: Urogenital TB is difficult to diagnose due to the lack of specific symptoms and signs. In the case of a nonfunctioning kidney without an obvious cause and a chronic spontaneous nephrocutaneous fistula, the possibility of associated renal TB should be kept in mind, especially in immunocompromised patients or in places where TB is a common health problem.

    We present a rare case of cholecystocutaneous fistula draining from an old surgical scar in the right upper abdominal quadrant following chronic calculous cholecystitis. A 71 year old male presented to the emergency department with a persistent bilious drainage from an old surgical scare, from surgical drainage, of the right upper abdominal quadrant for about a week. Cultures from the draining fluid grew Staphylococcus hominis, Escherichia coli and Klebsilla pneumoniae and tigecycline 50 mg twice a day was administrated intravenously to the patient according to sensitivity results. An abdominal US revealed the presence the gallbladder with calculi in a superficial position and the fistulogram revealed a cholecystocytaneous fistula arising from the fundus of the gallbladder. At laparotomy a fistula track was found connecting the gallbladder fundus to the skin, which was dissected and a cholecystectomy was performed. Spontaneous cholecystocutaneous fistula is rarely observed today, mostly as a complication of chronic calculous cholecystitis. Most often it arises from the gallbladder fundus and the clinical presentation is that of a painless draining sinus tract in the right upper quadrant. Diagnosis is aided by abdominal CT scan and ultrasound and treatment is with elective cholecystectomy and excision of the fistula. PMID:22352221

    Aim. This study was performed to evaluate the additional enteral nutrition (EN) in the efficacy of infliximab (IFX) compared with the conventional therapy in managing Crohn's disease (CD) complicated with intestinal fistulas. Methods. A total of 42 CD with intestinal fistulas were randomly divided into infliximab treatment group (n = 20) and conventional therapy group (n = 22). We evaluated the laboratory indexes, Crohn's disease activity index (CDAI), Crohn's disease simplified endoscopic score (SES-CD), and healing of fistula in the two groups before treatment, at 14 weeks, and at 30 weeks, respectively. Results. In the IFX treatment group, the CDAI score, the SES-CD, erythrocyte sedimentation rate, and C-reactive protein levels were significantly decreased during treatment compared with those before treatment. The body mass index and albumin levels were increased in both groups. Moreover, in the IFX treatment group, fistula healing was found in 8 at the 14th week and 18 at the 30th week, respectively, which was greater than that in the conventional therapy group. Conclusion. Our study suggested that infliximab combined with EN is an effective treatment for CD patients complicated with intestinal fistulas. PMID:27738427

    Colonic fistula is a rare and potentially critical sequela of severe acute pancreatitis, which requires surgical treatment. We report two cases that were successfully treated by a colectomy for colonic fistula associated with severe acute pancreatitis. Case 1 is a 71-year-old man infected with pseudocysts owing to severe acute pancreatitis that developed into a colonic fistula as an early complication with a resulting pancreatic abscess. This patient underwent a left hemicolectomy, a transverse colostomy, and drainage of the pancreatic abscess. He has done well without recurrent disease for 35 months following surgery. Case 2 is a 58-year-old woman who had a past history of drainage during a laparotomy for a pancreatic abscess induced by endoscopic retrograde cholangiopancreatography 10 years earlier. She was admitted to our hospital with left lateral abdominal pain and low-grade fever. Abdominal magnetic resonance imaging showed a retroperitoneal abscess and fistula to the descending colon. She underwent a left hemicolectomy and drainage of the retroperitoneal abscess. She has remained symptom-free for 20 months following surgery. The colonic fistula should therefore be recognized as a late complication during long-term follow-up as well as an early sequela associated with severe acute pancreatitis.

    Pulmonary tuberculosis (PTB) is a common infectious disease worldwide. However, mediastinal tuberculous lymphadenitis complicated by oesophageal involvement and oesophago-respiratory fistula is now uncommon due to improved anti-tuberculous regimes and better general awareness. The overall incidence of acquired oesophago-respiratory fistula due to infection is low, and therefore, the lesion is not often a frontrunner in differential diagnosis. Still, tuberculous oesophago-respiratory fistulae can potentially occur in patients with retroviral disease, as they tend to have atypical and more virulent manifestations. In this study, we report the case of multiple oesophago-respiratory fistulae in a patient with PTB and retroviral disease, and highlight the computed tomography features of these lesions as an atypical presentation of PTB in retroviral disease. Clinicians should suspect oesophago-respiratory fistulae if patients present with Ono’s sign, and remain particularly vigilant for patients with underlying PTB and retroviral disease, as early diagnosis and treatment could help to reduce mortality.

    Introduction: Ectopic tooth eruption may result owing to one of 3 processes: developmentalDisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. In rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. When the maxillary sinus is invaded, symptoms usually occur late in the process. Case Report: A 17 years old boy referred to department of Otolaryngology, Head and Neck Surgery of university of medical sciences, Tabriz_Iran in 2010 with chronic recurrent mucoprulent discharge from retromollar trigone , posterior to right superior alveolar ridge. CT scan revealed a dense mass resembling tooth, obstructing sinus ostium with homogenous opacity with ring enhancement, occupying whole sinus and expanding all walls. A Caldwell Luke approach in combination with endoscopy was selected. Conclusion: In the present patient, removal of ectopic tooth resolved the symptoms completely, the fistula obstructed and discharges discontinued. An ectopic tooth is a rare entity obstructing sinus ostium. The etiology of ectopic eruption has not yet been completely clarified, but many theories have been suggested,including trauma, infection, developmental anomalies and pathologic conditions, such as dentigerous cysts. In summary, although the ectopic teeth is rare but it would be assumed in presence of unilateral symptoms of sinonasal cavity. Therefore in peristant unilateral sinonasal symptoms we should complete examining of this site to rule out rare causes of these symptoms. PMID:24303440

    Introduction: Pharyngocutaneous fistula (PCF) is the most common complication after total laryngectomy. Its incidence is extremely variable, with values ranging from 3% and 65%. The management of this problem considerably increases the length and the cost of hospitalization. The aim of this study is to analyze the incidence, predisposing factors, and outcome of PCF in patients undergoing total laryngectomy in a Moroccan teaching hospital in Rabat, Morocco. Materials and Methods: This study is a retrospective study including 136 patients who underwent total laryngectomy for squamous cell carcinoma of the larynx in our institution, between January 2006 and December 2013. Socio-demographical, biological, surgical, and outcome data were included. Risk factors were analyzed for association with PCF formation. Results: The overall PCF rate was 27.8%. The mean age was 58 (32-82 years). Univariate analysis showed age (P= 0,028), hemoglobin (P=0,026), and previous tracheotomy (P=0,028) to be associated with the onset of PCF. However, multivariate analysis revealed that previous tracheotomy (P=0,028) and low level of preoperative hemoglobin (P=0,026) were highly associated with the occurrence of PCF. Conclusion: This is an original work performed in an African country with a large serie. Our findings suggest that age, previous tracheotomy, and low level of haemoglobin are risk factors for PCF onset after total laryngectomy in T4 squamous cell carcinoma. PMID:27280101
