To assess the primary and secondary patency rates for juxtaanastomotic stenoses, with or without superimposed thromboses, of arteriovenous hemodialysis fistulas treated with angioplasty and to compare it with National Kidney Foundation Dialysis Outcomes Quality Initiative treatment guidelines for stenosed and occluded arteriovenous fistulas (50% primary patency rate at 12 months). This study was a retrospective analysis, covering a period of 5(1/2) years. Forty-three hemodialysis patients were referred due to secondary fistula dysfunction, and angiography was diagnostic of a juxtaanastomotic lesion. Interventions consisted of standard angioplasty techniques along with thrombolysis and/or thrombectomy and intravascular stent placement as needed. Follow-up was performed at the attending dialysis center, and repeat angiography was performed as clinically required. Immediate postprocedural angiography demonstrated an angiographic success rate of 98%. Clinical success, with at least one session of normal dialysis, occurred in 95% of interventions. Primary patency rates at 12 months for the stenosed and stenosed/thrombosed fistulas were 56% and 64%, respectively. Secondary patency rates at 12 months were 64% and 63%, respectively. Half of the stenosed fistulas were patent at 1.5 years, 28% were patent at 4 years, and 13% remained patent at 6 years. No major complications were documented. Four minor complications, which did not require therapy, were noted. The results achieved are comparable to those reported for interventions at nonjuxtaanastomotic sites and exceed those quoted by the National Kidney Foundation Dialysis Outcomes Quality Initiative guidelines. Angioplastic interventions in a juxtaanastomatic area of arteriovenous fistulas are safe, promote prolonged patency, and postpone the need for surgical intervention or creation of a new fistula.

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 technicalmore » 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.« less

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 %,more » 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.« less

The current review and survey aim to assess the effectiveness of acellular dermal matrix (ADM) in the repair of cleft palate and oronasal fistula and to evaluate the current trends of ADM use in palate surgery. A systematic review of English articles was conducted using MEDLINE (1960 to July 1, 2016), the Cochrane Controlled Trials Register (1960 to July 1, 2016), and EMBASE (1991 to July 1, 2016). Additional studies were identified through a review of references cited in initially identified articles. Search terms included "cleft palate," "palatal," "oronasal fistula," "acellular dermal matrix," and "Alloderm®." An online survey was disseminated to members of the American Cleft Palate-Craniofacial Association to assess current trends in ADM use in palate surgery. All studies evaluating the outcome of primary palate repair or repair of oronasal fistula with the use of aceullar dermal matrix products were included in the review. Twelve studies met inclusion criteria for review. Studies were generally of low quality, as indicated by methodological index for non-randomized studies (MINORS) scores ranging from 7 to 14. The pooled estimate for fistula formation after primary palatoplasty following ADM use was 7.1%. The pooled estimate for recurrence of fistula after attempted repair using ADM was 11%. Thirty-six cleft surgeons responded to the online survey study. Of these, 45% used ADM in primary cleft palate repair, while 67% used ADM for repair of oronasal fistulae. Use of ADM products is commonplace in palate surgery. Despite this, there is a paucity of high-quality data demonstrating benefit. Further randomized controlled trials examining ADM in palate surgery are required to help develop structured guidelines and improve care.

An arteriovenous fistula is the optimal form of vascular access in patients with end-stage renal failure requiring haemodialysis. Unfortunately, approximately one-third of fistulae fail at an early stage. Different anaesthetic techniques can influence factors associated with fistula success, such as intraoperative blood flow and venous diameter. A regional anaesthetic brachial plexus block results in vasodilatation and improved short- and long-term fistula flow compared to the infiltration of local anaesthetic alone. This, however, has not yet been shown in a large trial to influence long-term fistula patency, the ultimate clinical measure of success.The aim of this study is to compare whether a regional anaesthetic block, compared to local anaesthetic infiltration, can improve long-term fistula patency. This study is an observer-blinded, randomised controlled trial. Patients scheduled to undergo creation of either brachial or radial arteriovenous fistulae will receive a study information sheet, and consent will be obtained in keeping with the Declaration of Helsinki. Patients will be randomised to receive either: (i) an ultrasound guided brachial plexus block using lignocaine with adrenaline and levobupivicaine, or (ii) local anaesthetic infiltration with lignocaine and levobupivicaine.A total of 126 patients will be recruited. The primary outcome is fistula primary patency at three months. Secondary outcomes include primary patency at 1 and 12 months, secondary patency and fistula flow at 1, 3 and 12 months, flow on first haemodialysis, procedural pain, patient satisfaction, change in cephalic vein diameter pre- and post-anaesthetic, change in radial or brachial artery flow pre- and post-anaesthetic, alteration of the surgical plan after anaesthesia as guided by vascular mapping with ultrasound, and fistula infection requiring antibiotics. No large randomised controlled trial has examined the influence of brachial plexus block compared with local anaesthetic infiltration on the long-term patency of arteriovenous fistulae. If the performance of brachial plexus block increases fistulae patency, this will have significant clinical and financial benefits as the number of patients able to commence haemodialysis when planned should increase, and the number of "redo" or revision procedures should be reduced. This study has been approved by the West of Scotland Research Ethics Committee 5 (reference no. 12/WS/0199) and is registered with the ClinicalTrials.gov database (reference no. NCT01706354).

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 reductionmore » 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.« less

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

Background A review was performed on entero-cutaneous fistula (ECF) repair and early recurrence, adding our twenty adult patients (65% had multiple fistulas). Methods The search yielded 4.098 articles but only 15 were relevant: 1.217 patients underwent surgery. The interval time between fistula’s diagnosis and operative repair was between 3 months and 1 year. A bowel resection with primary anastomosis was performed in 1.048 patients, 192 (18.3%) underwent a covering stoma: 856 patients (81.7%) had a fistula takedown in one procedure. Results The patients had 14.3% recurrence and 13.1% mortality rate. In our experience 75% were surgically treated after a period equal or above one year from fistula occurrence: surgery was very demolitive (in 40% remnant small bowel was less than 100 cm). We performed a bowel resection with a hand-sewn anastomosis (95%) without temporary stoma. In-hospital mortality was 0% and at discharge all were back to oral intake with 0% early re-fistulisation. Conclusions Literature supports our experience: ECF takedown could be safely performed after an adequate period of recovery from 3 months to one year from fistula occurrence. In our series primary repair (bowel resection plus reconnection surgery without temporary stoma) avoided an early recurrence without mortality. PMID:29182901

Perianal manifestations of Crohn’s disease (CD) are common and, of them, fistulas are the most common. Perianal fistulas can be extremely debilitating for patients and are often very challenging for clinicians to treat. CD perianal fistulas usually require multidisciplinary and multimodality treatment, including both medical and surgical approaches. The majority of patients require multiple surgical interventions. CD patients with perianal fistulas have a high rate of primary non-healing, surgical morbidity, and high recurrence rates. This has led to constant efforts to improve surgical management of this disease process. PMID:25331917

Postoperative lymphatic leakage following thyroid surgery represents a management problem with considerate potential morbidity, psychological, and economical impact. Conservative and surgical management strategies for high- and low-output lymph fistulas are inconsistent. Reliable criteria to predict outcome of conservative versus surgical treatment in clinically evident lymph fistula are lacking. A retrospective single-center chart review of consecutively quality-control-documented thyroid surgeries from January 1998 to December 2009 was performed to identify reported postoperative lymph fistulas. Documentation of surgical procedures, drainage, medical, and nutritional management was analyzed to identify risk factors for occurrence and criteria for management of evident lymph fistulas. There were 29 patients identified with postoperative clinical evidence of lymph fistulas following thyroid surgery; incidence was 0.5%. Indication to surgery comprised benign nodular goiter, recurrent nodular goiter, and thyroid carcinoma or local and lymphonodal carcinoma recurrences. There were 12 (41%) primary and 17 (59%) redo surgeries performed. Surgical procedures performed included thyroidectomy, completion thyroidectomy, and primary and redo central and lateral systematic microdissection of lymphatic compartments. All patients were initially submitted to fasting diet and medical treatment, successfully in 19 (66%), whereas ten (34%) patients underwent surgical intervention for fistula closure after failure of conservative treatment. Complications were one wound infection and fistula recurrence in five (26%) patients in the conservative group and two (20%) in the surgical group. Hospital stay was exceedingly prolonged in both groups with a median of 21 and 11 versus 6 days in patients with regular postoperative course following thyroid surgery. Data of this series support definition of the two categories of high- and low-output fistulas according to drainage collection with >300 versus <200 ml/day. Fasting in low-output fistula facilitates conservative treatment with closed drainage, whereas in high-output fistulas surgical intervention should be sought. Attendant criteria for treatment stratification are equally important, like patient's compliance, nutritional, and general health status as well as evidence for wound infection. Surgical closure of lymph fistula may be demanding when identification of the secreting fistula is limited and even muscle flap fortification may fail. Ultimately, in unsuccessfully reoperated fistula recurrences, open drainage may become necessary. Lymph fistulas cause significantly prolonged hospital stay, possible critical clinical decay, and unfavorable cosmetic and oncologic outcome while the superior management remains to be defined.

Laparoscopic surgery is considered in the treatment of diverticular fistula for the possible reduction of overall morbidity and complication rate if compared to open surgery. Aim of this review is to assess the possible advantages deriving from a laparoscopic approach in the treatment of diverticular fistulas of the colon. Studies presenting at least 10 adult patients who underwent laparoscopic surgery for sigmoid diverticular fistula were reviewed. Fistula recurrence, reintervention, Hartmann's procedure or proximal diversion, conversion to laparotomy were the outcomes considered. 11 non randomized studies were included. Rates of fistula recurrence (0.8%), early reintervention (30 days) (2%) and need for Hartmann's procedure or proximal diversion (1.4%) did not show significant difference between laparoscopy and open technique. there is still concern about which surgery in complicated diverticulitis should be preferred. Laparoscopic approach has led to less postoperative pain, shorter hospital stay, faster recovery and better cosmetic results. Laparoscopic resection and primary anastomosis is a possible approach to sigmoid fistulas but its advantages in terms of lower mortality rate and postoperative stay after colon resection with primary anastomosis should be interpreted with caution. When there is firm evidence supporting it, it is likely that minimally invasive surgery should become the standard approach for diverticular fistulas, thus achieving adequate exposure and better visualization of the surgical field. The lack of RCTs, the small sample size, the heterogeneity of literature do not allow to draw statistically significant conclusions on the laparoscopic surgery for fistulas despite this approach is considered safe.

Arteriovenous fistula is a lifeline for end-stage kidney disease patients on dialysis. The quality of the vein and artery to be used plays a crucial role in attaining a functioning, reliable and long-lasting arteriovenous fistula. The aim of the study is to present an alternative for haemodialysis access to preserve the upper arm vasculature for future use - the forearm loop arteriovenous fistula. From October 2015 to September 2016, 202 patients with chronic kidney disease (CKD), stages 4 and 5, underwent arteriovenous fistula creation at the Universiti Sains Malaysia Hospital, Malaysia. Nine patients, with severe atherosclerosis of the distal artery, but with satisfactory veins, underwent forearm loop arteriovenous fistula creation. Maturation of the fistula was based on the classification by the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF KDOQI). All nine patients who underwent forearm loop arteriovenous fistula have had diabetes mellitus for more than 10 years. Only one fistula failed to mature within 6 weeks. Two arteriovenous fistulas thrombosed at 3 and 5 months, respectively, after the commencement of haemodialysis. However, the other six matured fistulas are still functioning well after a year of regular usage. Distal forearm arteries in diabetics may be severely atherosclerotic. Forearm loop arteriovenous fistula can be considered as the primary access for cases decided as inconvenient for fistula creation due to severe occlusive atherosclerotic disease of the forearm arteries; in order to preserve upper arm veins for future access procedures.

2014-12-01

To investigate the value of collateral vein embolization (CVE) as a salvage treatment for nonmaturing native arteriovenous fistulae (AVFs) in patients requiring hemodialysis. A total of 49 patients undergoing CVE (N = 65) for immature native AVFs at a single institution were reviewed. The study included 42 patients treated by 56 embolizations. Average fistula age at time of intervention was 18.2 weeks. Each patient underwent angiographic evaluation for fistula immaturity, with clinical success defined by initiation of single-session hemodialysis through the native fistula. Fistula maturity was achieved in 32 of 42 patients (76.2%). No major complications occurred. Average time from CVE to fistula maturity was 38.4 days. Angioplasty done with CVE was found in a statistically higher percentage of patients with fistula success versus failure (31.3% vs 8.3%; P = .039). Radiocephalic fistulae were seen in a higher percentage of fistula failures compared with successes, but the results were not statistically significant (83.3% vs 59.4%; P = .054). Thirty-four patients underwent CVE without angioplasty, which resulted in successful fistula maturation in 22 cases (64.7%). Radiocephalic fistulae were again seen in a higher percentage of fistula failures compared with successes, but the findings did not meet statistical significance (81.8% vs 54.5%; P = .052). Coil embolization of competing collateral vessels as a salvage treatment for nonfunctioning autologous AVFs is a viable treatment option in the majority of patients. Patients with radiocephalic fistulae may be at higher risk for primary fistula failure, but the present data are inconclusive. Copyright © 2014 SIR. Published by Elsevier Inc. All rights reserved.

Objective To evaluate any association between female genital cutting and vesicovaginal fistula formation during obstructed labor. Methods A comparison was made between 255 fistula patients who had undergone Type I or Type II female genital cutting and 237 patients who had not undergone such cutting. Women were operated on at the Barhirdar Hamlin Fistula Centre in Ethiopia. Data points used in the analysis included age, parity, length of labor, labor outcome (stillbirth or not), type of fistula, site, size and scarring of fistula, outcomes of surgery (fistula closed, persistent incontinence with closed fistula, urinary retention with overflow, site, size, and scarring of any rectovaginal fistula and operation outcomes, as well as specific methods employed during the operation (utilization of a graft or not, application of a pubococcygeal or similar autologous sling, vaginoplasty, catheterization of ureters, and flap reconstruction of vagina). Primary outcomes were site of genitourinary fistula and persistent incontinence despite successful fistula closure. Results The only statistically significant differences between the two groups (p = 0.05) was a slightly greater need to place ureteral catheters at the time of surgery in women who had not undergone a genital cutting operation, and slightly higher use of a pubococcygeal sling at the time of fistula repair and a slightly longer length of labor (by 0.3 of a day) in women who had undergone genital cutting. Conclusion Type I and Type II female genital cutting are not independent causative factors in the development of obstetric fistulas from obstructed labor. PMID:20177289

Artificial nutritional support in patients with gastrointestinal fistulas.

PubMed

Dudrick, S J; Maharaj, A R; McKelvey, A A

1999-06-01

Gastrointestinal (GI) fistulas allow abnormal diversions of GI contents, digestive juices, water, electrolytes, and nutrients from one hollow viscus to another or to the skin, potentially precipitating a wide variety of pathophysiologic effects. Mortality rates have decreased significantly during the past few decades from as high as 40% to 65% to 5.3% to 21.3% largely as a result of advances in intensive care, nutritional support, antimicrobial therapy, wound care, and operative techniques. The primary causes of death secondary to enterocutaneous fistulas have been, and continue to be, malnutrition, electrolyte imbalances, and sepsis, especially in high-output fistulas, which continue to have a mortality rate of about 35%. Priorities in the management of GI fistulas include restoration of blood volume and correction of fluid, electrolyte, and acid-base imbalances; control of infection and sepsis with appropriate antibiotics and drainage of abscesses; initiation of GI tract rest including secretory inhibition and nasogastric suction; control and collection of fistula drainage with protection of the surrounding skin; and provision of optimal nutrition by total parenteral nutrition (TPN) or enteral nutrition (EN) (or both). The role of nutrition support in the management of enterocutaneous fistulas as either TPN or EN is primarily one of supportive care to prevent malnutrition, thereby obviating further deterioration of an already debilitated patient. It has been shown in several studies that TPN has substantially improved the prognosis of GI fistula patients by increasing the rate of spontaneous closure and improving the nutritional status of patients requiring repeat operations. Moreover, other studies have shown that nutritional support decreases or modifies the composition of the GI tract secretions and is thus considered to have a primary therapeutic role in the management of fistula patients. Finally, if a fistula has not closed within 30 to 40 days, or if it is unlikely to close because of a variety of collateral or compounding pathophysiologic conditions, consideration must be given to operative resection of the fistula while continuing to maintain the previous nutritional and metabolic support. The morbidity and mortality rates in such unfortunate patients remain high despite the many recent advances in surgical and metabolic technology.

In patients diagnosed with anal fistula, knowing the quality of life specifically related to the disease can help coloproctology specialists to choose the most appropriate therapeutic strategy for each case. The aim of our study is to analyzse and describe the factors related to the specific quality of life in a consecutive series of patients diagnosed with anal fistula. Observational, cross-sectional study carried out from March 2015 to February 2017. All patients were assessed in the colorectal surgery unit of a hospital in southeast of Spain. After performing an initial anamnesis and a physical examination, patients diagnosed with anal fistula completed the Quality of Life in Ppatients with Anal Fistula Questionnaire (QoLAF-Q). This questionnaire specifically measures quality of life in people with anal fistula and its score range is the following: zero impact = 14 points, limited impact = 15 to 28 points, moderate impact = 29 to 42 points, high impact = 43 to 56 points, and very high impact = 57 to 70 points. A total of 80 patients were included. The median score obtained in the questionnaire for the sample studied was 34.00 (range=14-68). Statistically significant differences between patients with "primary anal fistula" (n=65) and "recurrent anal fistula" (n=15) were observed (mean rank=42.96 vs. mean rank=29.83, p=0.048). Furthermore, an inverse proportion (P=.016) between "time with clinical symptoms" and "impact on quality of life" was found (<6 months: mean rank = 45.55; 6-12 months: mean rank = 44.39; 1-2 years: mean rank = 37.83; 2-5 years: mean rank = 22; >5 years: mean rank = 19.00). There were no statistically significant differences (P=.149) between quality of life amongst patients diagnosed with complex (mean rank = 36.13) and simple fistulae (mean rank = 43.59). Anal fistulae exert moderate-high impact on patients' quality of life. "Shorter time experiencing clinical symptoms" and the "presence of primary fistula" are factors that can be associated with worse quality of life. Copyright © 2018 AEC.

The management of an enterocutaneous fistula poses a significant challenge to surgeons and is often associated with a costly hospital stay and long-term discomfort. The use of fibrin glue in the fistula tract has been shown to promote closure of low output enterocutaneous fistulas. Our previous nonrandomized study demonstrated that autologous platelet-rich fibrin glue treatment significantly decreased time to fistula closure and promoted closure rates. However, there are several limitations in the study, which may lead to bias in our conclusion. Thus, a multicenter, randomized, controlled clinical trial is required. The study is designed as a randomized, open-label, three-arm, multicenter study in nine Chinese academic hospitals for evaluating the efficacy and safety of fibrin glue for sealing low-output fistulas. An established number of 171 fistula patients will undergo prospective random assignment to autologous fibrin glue, commercial porcine fibrin sealants or drainage cessation (1:1:1). The primary endpoint is fistula closure time (defined as the interval between the day of enrollment and day of fistula closure) during the 14-day treatment period. To our knowledge, this is the first study to evaluate the safety and efficacy of both autologous and commercial fibrin glue sealing for patients with low-output volume fistulas. NCT01828892 .

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. Technicalmore » 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.« less

Vascular access dysfunction is a leading cause of morbidity and mortality in patients requiring hemodialysis. Arteriovenous fistulae are preferred over synthetic grafts and central venous catheters due to superior long-term outcomes and lower health care costs, but increasing their use is limited by early thrombosis and maturation failure. ω-3 Polyunsaturated fatty acids (fish oils) have pleiotropic effects on vascular biology and inflammation and aspirin impairs platelet aggregation, which may reduce access failure. To determine whether fish oil supplementation (primary objective) or aspirin use (secondary objective) is effective in reducing arteriovenous fistula failure. The Omega-3 Fatty Acids (Fish Oils) and Aspirin in Vascular Access Outcomes in Renal Disease (FAVOURED) study was a randomized, double-blind, controlled clinical trial that recruited participants with stage 4 or 5 chronic kidney disease from 2008 to 2014 at 35 dialysis centers in Australia, Malaysia, New Zealand, and the United Kingdom. Participants were observed for 12 months after arteriovenous fistula creation. Participants were randomly allocated to receive fish oil (4 g/d) or matching placebo. A subset (n = 406) was also randomized to receive aspirin (100 mg/d) or matching placebo. Treatment started 1 day prior to surgery and continued for 12 weeks. The primary outcome was fistula failure, a composite of fistula thrombosis and/or abandonment and/or cannulation failure, at 12 months. Secondary outcomes included the individual components of the primary outcome. Of 1415 eligible participants, 567 were randomized (359 [63%] male, 298 [53%] white, 264 [47%] with diabetes; mean [SD] age, 54.8 [14.3] y). The same proportion of fistula failures occurred in the fish oil and placebo arms (128 of 270 [47%] vs 125 of 266 [47%]; relative risk [RR] adjusted for aspirin use, 1.03; 95% CI, 0.86-1.23; P = .78). Fish oil did not reduce fistula thrombosis (60 [22%] vs 61 [23%]; RR, 0.98; 95% CI, 0.72-1.34; P = .90), abandonment (51 [19%] vs 58 [22%]; RR, 0.87; 95% CI, 0.62-1.22; P = .43), or cannulation failure (108 [40%] vs 104 [39%]; RR, 1.03; 95% CI, 0.83-1.26; P = .81). The risk of fistula failure was similar between the aspirin and placebo arms (87 of 194 [45%] vs 83 of 194 [43%]; RR, 1.05; 95% CI, 0.84-1.31; P = .68). Neither fish oil supplementation nor aspirin use reduced failure of new arteriovenous fistulae within 12 months of surgery. anzctr.org.au Identifier: CTRN12607000569404.

To investigate the clinical feasibility and efficacy of Y-shaped self-expandable covered metal stents (Y-stents) in the management of thoracostomach-airway fistula. Retrospective analysis was performed for 108 patients treated for thoracostomach-airway fistula with Y-shaped self-expandable coated metal stents between April 2003 and October 2014. Y-stents were designed based on the dimensions of trachea and bronchus and sites of the fistula and then were inserted under DSA monitoring. There were 65 cases with single big Y-stent placement, 26 cases with single small Y-stent placement, 23 cases with double Y-stents placement, and 1 case with 3 Y-stents placement. Stent implantation was successfully accomplished with single manipulation in all patients. Complete occlusion of the fistula was obtained in 104 patients after the primary manipulation, and 4 patients required a secondary manipulation where a double Y-stents was inserted because of failure of primary manipulate. Ninety-two patients completed the follow-up , while 16 were lost. Fifty-nine patients died while 33 were alive with marked improvement in their quality of life. The placement of Y-stents can effectively occlude the thoracostomach-airway fistula in patients who had had the esophageal tumors resected. The technique is not only feasible but reliable to improve the quality of life of the patients.

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.

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 adjacentmore » 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.« less

Digestive system fistula originates most frequently as a complication after surgical procedures, less often occurs in the course of inflammatory diseases, but it can also result from neoplasm and injuries. THE AIM OF THE STUDY was to analyze the causes and retrospectively assess the perioperative procedures as well as the results of digestive system fistula treatment. MATERIAL AND METHODS. Own experience in digestive system fistula treatment was presented. The subject group consisted of 32 patients treated at the General Surgery, Oncology and Endocrinology Clinical Department between 01.05.2005 and 30.04.2010 due to different digestive tract diseases. The causes of the occurrence of digestive system fistula, methods and results of treatment were analyzed. RESULTS. The analysis covered 32 patients with digestive system fistula, among them 15 men and 17 women. Average age for men was 57 years (20-78), and for women 61 years (24-88). In 11 patients idiopathic fistula causally connected with primary inflammatory disease (7 cases) and with neoplasm (4 cases) was diagnosed, in 19 patients fistula was the result of complications after surgery, in 2 - after abdominal cavity injury. Recovery from fistula was achieved in 23 patients (72%) with the use of individually planned conservative therapy (TPN, EN, antibiotics, drainage, and others) and surgery, depending on the needs of individual patient. 5 patients (16%) died, whereas in 4 left (12%) recovery wasn't achieved (fistula in palliative patients, with advanced stages of neoplasm - bronchoesophageal fistula, the recurrence of uterine carcinoma). CONCLUSIONS. Recently the results of digestive system fistula treatment showed an improvement which manifests itself in mortality decrease and shortening of fistula healing time. Yet, digestive system fistula as a serious complication still poses a very difficult surgical problem.

Laparoscopic sleeve gastrectomy (LSG) is gaining acceptance as the preferred option for treating obesity. Risks of leak and subsequent fistula after sleeve gastrectomy still present significant concerns in clinical practice. This current series presents unusual fistulas post-LSG and their surgical management. The series presents chronic leaks that have progressed into fistulas. Three patients with fistulas are presented: gastrocolic, gastropleural, and gastrosplenic. Surgical intervention was warranted in all cases with en-bloc resection of the fistula with subtotal gastrectomy and Roux-en-Y esophagojejunostomy reconstruction. A subtotal colectomy with ileo-descending colon anastomosis was additionally necessary in the gastrocolic patient. The patients with the gastropleural and gastrosplenic fistulas were discharged home on postoperative Day 6 and Day 7, respectively. The patient with the gastrocolic fistula had an extended postoperative hospital course and was discharged home on postoperative Day 35. All cases were negative for staple line leaks. To date, the fistulas healed with no recurrence. En-bloc resection of the fistula with proximal gastrectomy and Roux-en-Y esophagojejunostomy (PGRYEJ) is a surgical option to treat chronic staple line leakage when non-operative therapy is rendered ineffective. Adequate preoperative planning with optimization of nutritional status and control of local and systemic sepsis is paramount for ultimate success. A symptomatic leak requires immediate operation regardless of the time interval between the primary sleeve operation and appearance of the leak.

This review provides a blueprint to deal with the diagnosis and management of recurrent tracheoesophageal fistulas. A retrospective review over 27 years found 26 recurrent tracheoesophageal fistulas. Descriptive statistical analyses were performed. In this cohort of 26 patients, 18 had a leak after their primary operation; and 22 had respiratory symptoms leading to the discovery of the recurrent fistula. The diagnosis was made by contrast study in 24. The repairs entailed placing a catheter through the fistula; separating the trachea and esophagus using sharp dissection; and placing tissue, preferably pericardium, between the suture lines. Postoperative complications included 7 anastamotic leaks, 4 strictures, and 3 recurrent fistulas. Long-term follow-up (median of 84 months) showed that 21 took all of their nutrition by mouth, 3 were tube fed, and 2 required a combination. Of the 23 patients with growth chart data, 16 fell in the first quartile of the growth chart, whereas none fell between the 75th and 100th percentile. This series, the largest to date, describes characteristics of recurrent tracheoesophageal fistulas, including techniques to make the diagnosis and provide a secure closure of the fistula, and the long-term outcomes of these patients.

Surgical treatment of high anal fistulas is associated with the potential risk of faecal incontinence and recurrence. The primary aim of this study was to determine the accuracy of three-dimensional endoanal ultrasound (3D-EAUS) in the assessment of height and type of anal fistulas, compared to the intra-operative findings (gold standard). The secondary aim was to evaluate the inter-observer reproducibility of 3D-EAUS. The study design was a prospective analysis of retrospective data. 299 patients (202 men), mean age 45.3 years, who underwent surgery for anal fistulas, were included. All patients were preoperatively assessed by 3D-EAUS. Two readers independently reviewed the volumes to determine the type and height of fistulas. Sensitivity, specificity, positive and negative predictive values, proportion of agreements and Cohen's kappa coefficient (κ) were calculated for both examiners. Ultrasound findings were compared with intra-operative data (reference standard), evaluated blindly by the surgeons. At surgery, 201 (67%) were transsphincteric, 49 (16%) suprasphincteric, 47 (16%) intersphincteric and two (1%) extrasphincteric fistulas. Intra-operatively, 177 (59%) were low and 122 (41%) high fistulas. The overall accuracy of 3D-EAUS was 91% for fistula type (271/299 fistulas: 97% transsphincteric, 100% intersphincteric, 57% suprasphincteric, 0% extrasphincteric) and 92% for fistula height (275/299 fistulas: 80% high and 100% low). Both readers reported very good agreement with surgery in the assessment of fistula type (proportion of agreement 0.88, κ = 0.89) and height (proportion of agreement 0.90, κ = 0.91). 3D-EAUS is an accurate and reproducible modality for the assessment of type and height of anal fistulas.

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 atmore » 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.« less

Anal fistula anatomy and its relationship with anal sphincters are important factors influencing the results of surgical management. Pre-operative definitions of fistulous track(s) and the internal opening play a primary role in minimizing damage to the sphincters and recurrence of the fistula. To evaluate the relative accuracy of digital examination and endoanal ultrasound for pre-operative assessment of anal fistula by comparing operative findings. A retrospective review was conducted of all patients with anal fistula admitted to the surgical unit between May 2008 and May 2012. Physical examination and hydrogen peroxide-enhanced endoanal ultrasound (utilising a 10 MHz endoprobe, HITACHI: EUB-7500), were performed in 142 consecutive patients. Results were matched with surgical features to establish their accuracy in preoperative anal fistula assessment. A total of 142 patients (107 men, 35 women), 28 of whom had had previous surgery, were included in the study. Their mean age was 40 (range 18-71) years and their mean BMI was 26.37 (range 17.30-36.11) kg/m². The majority of the fistulas were transphincteric (90.4%) and the rest were intersphincteric (9.6%). The accuracy rates of clinical examination and endoanal ultrasound were 55.63 and 95.07 percent (p < 0.01), respectively. Endoanal ultrasound is superior to digital examination for pre-operative classification of anal fistula

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

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

Colovesical fistulas originating from complicated sigmoid diverticular disease are rare. The primary aim of this review was to evaluate the role of laparoscopic surgery in the treatment of this complication. The secondary aim was to determine the best surgical treatment for this disease. A systematic search was conducted for studies published between 1992 and 2012 in PubMed, the Cochrane Register of Controlled Clinical Trials, Scopus, and Publish or Perish. Studies enrolling adults undergoing fully laparoscopic, laparoscopic-assisted, or hand-assisted laparoscopic surgery for colovesical fistula secondary to complicated sigmoid diverticular disease were considered. Data extracted concerned the surgical technique, intraoperative outcomes, and postoperative outcomes based on the Cochrane Consumers and Communication Review Group's template. Descriptive statistics were reported according to the PRISMA statement. In all, 202 patients from 25 studies were included in this review. The standard treatment was laparoscopic colonic resection and primary anastomosis or temporary colostomy with or without resection of the bladder wall. Operative time ranged from 150 to 321 min. It was not possible to evaluate the conversion rate to open surgery because colovesical fistulas were not distinguished from other types of enteric fistulas in most of the studies. One anastomotic leak after bowel anastomosis was reported. There was zero mortality. Few studies conducted follow-up longer than 12 months. One patient required two reoperations. Laparoscopic treatment of colovesical fistulas secondary to sigmoid diverticular disease appears to be a feasible and safe approach. However, further studies are needed to establish whether laparoscopy is preferable to other surgical approaches.

Postoperative enteric fistula is a serious complication and cause of death following gastrointestinal (GI)-tract surgery. Many reports have demonstrated the effectiveness of parenteral nutrition in the spontaneous closure of enteric fistula. Our study was aimed at analyzing the prognostic factors of parenteral nutritional support in the treatment of enteric fistula for patients with GI-tract cancer following surgery. GI-tract cancer patients receiving surgical interventions, which then unfortunately developed enteric fistula, were included in our study. All of them had to have received parenteral nutrition soon after leakages were recognized, and they were subsequently divided into successful and unsuccessful (classified as "failure") groups according to spontaneous closure of fistula or not, respectively. The studied patients' laboratory data were collected to identify the clinically relevant prognostic factors. Fifty-three primary GI-tract cancer patients with postoperative enteric fistulas were enrolled into our study. Of these, 33 patients were considered as successful parenteral nutritional therapy (successful group) and the other 20 patients (failure group) were not. After a period of parenteral nutritional therapy, serum total bilirubin, creatinine, C-reactive protein (CRP), hemoglobin, and albumin were significantly different between these two groups (all p < .05). Using a multivariate logistic regression analysis, it was determined that increased serum albumin level was an independent predictive factor of successful management for enteric fistula (p = .029), in addition to the well-known lower drainage amount (< 500 mL/day) from the enteric fistula (p = .013). Our observations show that both serum albumin levels and drainage amounts from the enteric fistula can be potentially used as important prognostic predictors of healing enteric fistula under total parenteral nutrition in patients following surgery for GI-tract malignancies.

Oronasal fistula represents a functional problem after cleft palate repair; its closure is technically difficult with a high recurrence rate after primary treatment. The aim of this study was to evaluate the efficacy of closure of oronasal fistula using 2 layers of oral mucoperiosteum in a V-Y manner. Fourteen patients were subjected for repair of their oronasal fistulas using 2 layers; the first is the oral mucoperiosteum that is elevated and inverted to close the nasal side as a hinge flap, and the second is also the oral mucoperiosteum that is elevated and sutured in a V-Y manner to close the oral side. In all cases, the fistula was completely closed at first attempt, no cases developed operative or postoperative complications. Recurrence with not recorded in any case after a follow-up period of at least 12 months. Closure of oronasal fistula of the hard palate that may develop after cleft palate repair using a two-layer closure in V-Y manner is an easy and ideal method with a high success rate.

Background A large proportion of newly created arteriovenous fistulas cannot be used for dialysis because they fail to mature adequately to support the hemodialysis blood circuit. The Hemodialysis Fistula Maturation (HFM) Study was designed to elucidate clinical and biological factors associated with fistula maturation outcomes. Study Design Multicenter prospective cohort study. Setting & Participants Approximately 600 patients undergoing creation of a new hemodialysis fistula will be enrolled at 7 centers in the United States and followed up for as long as 4 years. Predictors Clinical, anatomical, biological, and process-of-care attributes identified pre-operatively, intra-operatively, or post-operatively. Outcomes The primary outcome is unassisted clinical maturation defined as successful use of the fistula for dialysis for four weeks without any maturation-enhancing procedures. Secondary outcomes include assisted clinical maturation, ultrasound-based anatomical maturation, fistula procedures, fistula abandonment, and central venous catheter use. Measurements Pre-operative ultrasound arterial and venous mapping, flow-mediated and nitroglycerin-mediated brachial artery dilation, arterial pulse wave velocity, and venous distensibility; intra-operative vein tissue collection for histopathological and molecular analyses; post-operative ultrasounds at 1 day, 2 weeks, 6 weeks, and prior to fistula intervention and initial cannulation. Results Assuming complete data, no covariate adjustment, and unassisted clinical maturation of 50%, there will be 80% power to detect ORs of 1.83 and 1.61 for dichotomous predictor variables with exposure prevalences of 20% and 50%, respectively. Limitations Exclusion of two-stage transposition fistulas limits generalizability. The requirement for study visits may result in a cohort that is healthier than the overall population of patients undergoing fistula creation. Conclusions The HFM Study will be of sufficient size and scope to 1) evaluate a broad range of mechanistic hypotheses, 2) identify clinical practices associated with maturation outcomes, 3) assess the predictive utility of early indicators of fistula outcome, and 4) establish targets for novel therapeutic interventions to improve fistula maturation.

Abstract Esophageal fistula is a critical adverse event in patients treated with chemoradiotherapy (CRT) for locally advanced esophageal cancer. However, risk factors associated with esophageal fistula formation in patients receiving CRT have not yet been elucidated. We retrospectively analyzed data obtained from 140 patients who were enrolled in a phase II/III trial comparing low-dose cisplatin with standard-dose cisplatin administered in combination with 5-flurouracil and concomitant radiotherapy. Inclusion criteria were performance status (PS) 0 to 2 and histologically proven thoracic esophageal cancer clinically diagnosed as T4 and/or unresectable lymph node metastasis for which definitive CRT was applicable. Risk factors for esophageal fistula were examined with univariate analysis using Fisher exact test and multivariate analysis using logistic regression models. Esophageal fistula was observed in 31 patients (22%). Of these, 6 patients developed fistula during CRT. Median time interval between the date of CRT initiation and that of fistula diagnosis was 100 days (inter quartile range, 45–171). Esophageal stenosis was the only significant risk factor for esophageal fistula formation both in univariate (P = 0.026) and in multivariate analyses (odds ratio, 2.59; 95% confidence interval, 1.13–5.92, P = 0.025). Other clinicopathological factors, namely treatment arm, age, sex, PS, primary tumor location, T stage, lymph node invasion to adjacent organs, blood cell count, albumin level, and body mass index, were not risk factors fistula formation. Esophageal stenosis was a significant risk factor for esophageal fistula formation in patients treated with CRT for unresectable locally advanced thoracic esophageal squamous cell carcinoma.

The purpose of this study was to assess the usefulness of percutaneous intervention with transarterial approach in the salvage of nonmaturing native fistulas status post transvenous approach failure. Eight patients (M:F=2:6; mean age, 56.8 years) underwent percutaneous intervention with antegrade transarterial approach when the retrograde transvenous approach failed. Mean time from fistula creation to fistulography was 80.5 days. Five patients had brachiocephalic fistulas and three had radiocephalic fistulas. Brachial or radial arterial access was performed using real-time ultrasound guidance, and balloon angioplasty was performed for hemodynamically significant (>50%) stenosis. Technical and clinical success and complications were evaluated. Patency following percutaneous intervention was estimated with the Kaplan-Meier method. Technical success was achieved in 87.5% (seven of eight patients). Clinical success of normal hemodialysis (fistula maturation) occurred in 87.5% (seven of eight patients). One minor complication (regional hematoma) occurred in one patient. Mean primary patency at 6, 12, and 18 months was 75%, 56.2%, and 37.5%, respectively. Additional angioplasty (n=3) resulted in mean secondary patency at 12 and 18 months of 87.5% and 87.5% of the patients, respectively. In conclusion, percutaneous intervention with the transarterial approach can be a useful method for salvage of nonmaturing native fistulas when the transvenous approach fails.

The objective of this study is to assess the feasibility of primary posterior sagittal anorectoplasty in vestibular fistula without a covering colostomy. Girls presenting from July 1997 to July 2005 with vestibular fistula were included prospectively in the study, in a nonrandomized manner, after excluding those with megarectosigmoid and pouch colon. All underwent primary posterior sagittal anorectoplasty after total gut irrigation with normal saline. They were kept nil per oral until the fifth postoperative day. No patient was started on anal dilatation. Patients were assessed for immediate and delayed complications as well as voluntary bowel movements and continence. A total of 72 patients with an age range of 1.5 months to 8 years (median, 9 months) were studied after excluding 7 with pouch colon and 3 with megarectosigmoid. Of the 72, 3 had undergone previous surgery. Follow-up ranged from 7 months to 8 years. No wound dehiscence or recurrence of fistula was noted. There were 5 mild wound infections. At 1 month postoperative, all patients had 1 to 3 stools per day with no episodes of soiling. None required anal dilatations, laxatives, or enemas. Primary posterior sagittal anorectoplasty in vestibular fistula can be performed without a covering colostomy provided fecal contamination of the wound can be kept to the minimum in the first postoperative week. We achieve this by thorough total gut irrigation preoperatively and keeping the child nil per oral for the first 5 postoperative days. Continence rates are excellent and postoperative constipation is unlikely if megarectosigmoid and pouch colon are ruled out before surgery. Anal dilatation is not required after surgery.

Esophageal involvement in Crohn's disease is very rare. In only a small subgroup of these patients -- up to date fourteen cases have been described in the literature -- the course of the illness may be complicated by esophageal fistula formation. The therapy for fistulizing esophageal Crohn's disease so far has been disappointing, recurrence and progression are likely, and surgery still is the primary treatment modality for refractory patients. We here present a case of severe Crohn's disease with an esophagobronchial fistula and the successful closure of the fistula tract with the novel liquid polymer sealant "Onyx". This approach offers a new option for the treatment of this rare complication of Crohn's disease and should be considered if surgery is not possible.

The aim of this study was to identify risk factors related to pancreatic fistula after left pancreatectomy, considering the difference between the use of mechanical suture and the manual suture to close the pancreatic stump. Sixty-eight patients, undergoing left pancreatectomy, were included in this study during a 10-year period. Eight possible risk factors related to pancreatic fistula were examined, such as demographic data (age and sex), pathology (pancreatic and extrapancreatic), technical characteristics (stump closure, concomitant splenectomy, additional procedures), texture of pancreatic parenchyma, octreotide therapy. Fourty-one patients (60%) underwent left pancreatectomy for primary pancreatic disease and 27 (40%) for extrapancreatic malignancy. Postoperative mortality and morbidity rates were 1.5% and 35%, respectively. Fourteen patients (20%) developed pancreatic fistula: 4 of them were classified as Grade A, 9 as Grade B and only one as Grade C. Three factors have been significantly associated to the incidence of pancreatic fistula: none prophylactic octreotide therapy, spleen preserving and soft pancreatic texture. It's still unclear the influence of pancreatic stump closure (stapler vs hand closure) in the onset of pancreatic fistula. In this study the incidence of pancreatic fistula after left pancreatectomy has been 20%. This rate is lower for patients with fibrotic pancreatic tissue, concomitant splenectomy and postoperative prophylactic octreotide therapy.

Context The arteriovenous fistula is the preferred type of vascular access for hemodialysis because of lower thrombosis and infection rates and lower health care expenditures compared with synthetic grafts or central venous catheters. Early failure of fistulas due to thrombosis or inadequate maturation is a barrier to increasing the prevalence of fistulas among patients treated with hemodialysis. Small, inconclusive trials have suggested that antiplatelet agents may reduce thrombosis of new fistulas. Objective To determine whether clopidogrel reduces early failure of hemodialysis fistulas. Design, Setting, and Participants Randomized, double-blind, placebo-controlled trial conducted at 9 US centers composed of academic and community nephrology practices in 2003–2007. Eight hundred seventy-seven participants with end-stage renal disease or advanced chronic kidney disease were followed up until 150 to 180 days after fistula creation or 30 days after initiation of dialysis, whichever occurred later. Intervention Participants were randomly assigned to receive clopidogrel (300-mg loading dose followed by daily dose of 75 mg; n = 441) or placebo (n = 436) for 6 weeks starting within 1 day after fistula creation. Main Outcome Measures The primary outcome was fistula thrombosis, determined by physical examination at 6 weeks. The secondary outcome was failure of the fistula to become suitable for dialysis. Suitability was defined as use of the fistula at a dialysis machine blood pump rate of 300 mL/min or more during 8 of 12 dialysis sessions. Results Enrollment was stopped after 877 participants were randomized based on a stopping rule for intervention efficacy. Fistula thrombosis occurred in 53 (12.2%) participants assigned to clopidogrel compared with 84 (19.5%) participants assigned to placebo (relative risk, 0.63; 95% confidence interval, 0.46–0.97; P = .018). Failure to attain suitability for dialysis did not differ between the clopidogrel and placebo groups (61.8% vs 59.5%, respectively; relative risk, 1.05; 95% confidence interval, 0.94–1.17; P = .40). Conclusion Clopidogrel reduces the frequency of early thrombosis of new arteriovenous fistulas but does not increase the proportion of fistulas that become suitable for dialysis.

Fistulae between the colon and upper gastrointestinal tract are distressing and uncommon complications of malignancies involving this region. We report a case of a middle-aged man with a locally advanced and metastatic distal transverse colon malignancy who presented with a duodenocolic fistula proximal to the primary tumor and underwent palliative surgery. A 50-year-old Sri Lankan man presented to our hospital with a history of feculent vomiting of 1 week's duration preceded by worsening constipation and abdominal fullness of 2 months' duration. He also complained of anorexia and significant weight loss over the previous month. His physical examination was unremarkable except for his wasted appearance. Flexible sigmoidoscopy done at his local hospital had not revealed any abnormality in the left colon. Gastroduodenoscopy did not reveal fecal matter or any mucosal abnormalities in the stomach or duodenum. An abdominal contrast-enhanced computed tomographic scan showed a mid-to-distal transverse colonic tumor with a duodenocolic fistula proximal to the primary lesion. At laparotomy, he was found to have an unresectable, locally advanced mid transverse colon tumor with diffuse peritoneal and mesenteric deposits and mild ascites. Palliative end ileostomy and gastrojejunostomy were performed before closure. Histology from the malignant deposits revealed a well-differentiated adenocarcinoma. He made an uneventful recovery with good symptomatic relief. Malignant gastric or duodenocolic fistulae are uncommon complications of locally advanced colonic malignancies with direct invasion to the stomach or duodenum. Although the characteristic clinical presentation of feculent vomiting suggests the diagnosis, cross-sectional imaging is confirmative in addition to staging the disease. Management is guided by disease stage, nutritional status, and the general condition of the patient and ranges from extensive bowel resection including the fistula to palliative options.

The aim of this retrospective study was to assess our experience of 41 patients with anal fistulae treated with video-assisted anal fistula treatment (VAAFT). Forty-one consecutive patients with cryptoglandular anal fistulae were included. Patients with low intersphincteric anal fistulae or those with gross perineal abscess were excluded. Eleven (27 %) patients had undergone prior fistula surgery with 5 (12 %) having had three or more previous operations. All patients underwent the diagnostic phase as well as diathermy and curettage of the fistula tracts during VAAFT. Primary healing rate was 70.7 % at a median follow-up of 34 months. Twelve patients recurred or did not heal and underwent a repeat VAAFT procedure utilising various methods of dealing with the internal opening. There was a secondary healing rate of 83 % with two recurrences. Overall, stapling of the internal opening had a 22 % recurrence rate, while anorectal advancement flap had a 75 % failure rate. There was no recurrence seen in six cases after using the over-the-scope-clip (OTSC(®)) system to secure the internal opening. VAAFT is useful in the identification of fistula tracts and enables closure of the internal opening. Adequate closure is essential with the method used to close large or fibrotic internal openings being the determining factor for success or failure. The OTSC system delivered the most consistent result without leaving a substantial perianal wound. Ensuring thorough curettage and drainage of the tract during VAAFT is also important to facilitate healing. We believe that this understanding will bring about a decrease in the high recurrence rates currently seen in many series of anal fistulae.

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 increasemore » 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.« less

Speech-correcting surgeries (pharyngoplasty) are performed to correct velopharyngeal insufficiency (VPI). This study aimed to analyze the need for speech-correcting surgery in children with isolated cleft palate (ICP) and to determine differences among cleft extent, gender, and primary technique used. In addition, we assessed the timing and number of secondary procedures performed and the incidence of operated fistulas. Retrospective medical chart review study from hospital archives and electronic records. These comprised the 423 consecutive nonsyndromic children (157 males and 266 females) with ICP treated at the Cleft Palate and Craniofacial Center of Helsinki University Hospital during 1990 to 2016. The total incidence of VPI surgery was 33.3% and the fistula repair rate, 7.8%. Children with cleft of both the hard and soft palate (n = 300) had a VPI secondary surgery rate of 37.3% (fistula repair rate 10.7%), whereas children with only cleft of the soft palate (n = 123) had a corresponding rate of 23.6% (fistula repair rate 0.8%). Gender and primary palatoplasty technique were not considered significant factors in need for VPI surgery. The majority of VPI surgeries were performed before school age. One fifth of patients receiving speech-correcting surgery had more than one subsequent procedure. The need for speech-correcting surgery and fistula repair was related to the severity of the cleft. Although the majority of the corrective surgeries were done before the age of 7 years, a considerable number were performed at a later stage, necessitating long-term observation.

In spite of the acquired experience with laparoscopic common bile duct exploration (LCBDE) for choledocholithiasis management, there is still a risk of biliary leakage of 5% to 15% following choledochotomy closure. We evaluate the usefulness of fibrin-collagen sealants to reduce the incidence of biliary fistula after laparoscopic choledochorrhaphy. We report a retrospective analysis of 96 patients undergoing LCBDE from March 2009 to March 2017, whose closure of the bile duct was completed by antegrade stenting and choledochorraphy or by performing a primary suture. The study population was divided into two groups according to whether they received a collagen-fibrin sealant covering the choledochorrhaphy or not, analyzing the incidence of postoperative biliary fistula in each group. Thirty-nine patients (41%) received a fibrin-collagen sponge while the bile duct closure was not covered in the remaining 57 patients (59%). The incidence of biliary fistula was 7.7% (3 patients) in the first group and 14% (8 patients) in the second group (P=.338). In patients who underwent primary choledochorraphy, the fibrin-collagen sealant reduced the incidence of biliary leakage significantly (4.5% vs. 33%, P=.020), which was a protective factor with an odds ratio of 10.5. Fibrin-collagen sealants may decrease the incidence of biliary fistula in patients who have undergone primary bile duct closure following LCBDE. Copyright © 2018 AEC.

A five-month-old intact/male Boxer dog was presented 5-days following bite wound trauma to the maxillary region resulting in an oronasal fistula extending from the maxillary canine teeth to the soft palate. Multiple surgical procedures using local, buccal mucosal flaps failed to repair the oronasal fistula. Free tissue transfer of the rectus abdominis myoperitoneal flap using microvascular surgical techniques was successful in providing soft tissue reconstruction of the hard palate area. Complications of these surgical techniques included muscle contraction and subsequent muzzle distortion. Small, refractory oronasal fistulae at the perimeter of the myoperitoneal flap were repaired by primary wound closure.

Transposed brachial-basilic arteriovenous fistulas versus prosthetic upper limb grafts: a meta-analysis.

Controversy exists regarding the best type of arteriovenous (AV) fistula to be formed in secondary and tertiary access procedures when primary fistulas have failed. This meta-analysis aimed to compare transposed brachial-basilic AV fistulas (BBAVFs) with upper limb AV prosthetic grafts. A literature search of the MEDLINE and SCOPUS databases was performed to identify comparative studies reporting outcomes for both BBAVFs with upper limb AV prosthetic grafts. Meta-analysis techniques were applied to identify differences in outcomes between the two groups regarding primary and secondary 1-year failure rates. Eleven relevant studies, involving 1509 patients, met the inclusion criteria and were incorporated in the final analysis; however, only one was randomised controlled trial. The pooled odds' ratio (OR) estimate for the primary and secondary failure rates at 1 year was 0.67 (CI 0.41-1.09) and 0.88 (CI 0.69-1.12), respectively, showing no difference in the outcome between the two groups. The re-intervention rate was higher for prosthetic grafts (0.54 per BBAVF versus 1.32 per graft). In a small subgroup of two studies comparing BBAVFs with forearm grafts the pooled estimate for 1-year primary failure rate was in favour of the BBAVF group (OR 0.3, CI 0.15-0.58, p=0.0004) suggesting that forearm grafts were inferior having a 3-fold risk of failure at 1 year. This analysis supports the use of BBAVF early in difficult access cases prior to the use of prosthetic grafts. However, the latter conclusion is debatable due to heterogeneity, small size and non-randomised design of the included studies.

Artificial embolization of carotid-cavernous fistula with post-operative patency of internal carotid artery

This report deals with a patient of 86 who developed a carotid-cavernous fistula. Artificial embolization alone was considered the safest treatment for this patient and proved to be adequate. Post-operative preservation of the patency of the internal carotid artery was demonstrated by angiography. We believe this method is particularly appropriate for carotid-cavernous fistulas if it is demonstrated by angiography that the major blood flow of the carotid artery pours into the fistula. A soft-iron clip attached to the muscle can be used for external and forceful guidance of the embolus into the fistula with the help of an electromagnet, hence the patency of the internal carotid artery can be preserved. The embolus should be introduced through the external carotid artery. This is the only case known to us in which patency of the internal carotid artery was post-operatively maintained. We have reviewed 545 reported cases of surgically treated carotid-cavernous fistulas and analysed the results from simple cervical carotid ligation to the more sophisticated methods of artificial embolizations. The results obtained by artificial embolization have been consistently good, while the other techniques have failed in large percentages. Artificial embolization should be used as the primary treatment for carotid-cavernous fistula, since ligation of the internal carotid artery precludes its embolization at a later date.

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. 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. 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). 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). PJ of the pancreatic stump during DP does not reduce pancreatic fistula compared with stapler closure.

Technique to Avoid Hemodialysis Catheter in Patients with Failing Aneurysmal Arteriovenous Fistula by Creating a Concomitant New Arteriovenous Fistula.

PubMed

Lara, Kelly A; Chua, Rochelle Anne; Vo, Trung D

2018-05-01

Autogenous arteriovenous fistula (AVF) is the primary recommended access for hemodialysis. Long-term use will not uncommonly result in AVF aneurysmal degeneration. Aneurysm-associated complications encompass pain, skin ulceration, infection, thrombosis, cannulation difficulties, and life-threatening bleeding. Various methods to repair aneurysmal AVFs have been described. However, there may be circumstances when this is not possible and require insertion of a temporary hemodialysis catheter (HDC) until a new arteriovenous access is created. We describe a case series of creating a new simultaneous AVF while continuing to use the primary failing aneurysmal AVF to avoid placement of an HDC. Once the new AVF becomes operational, the primary aneurysmal AVF can be abandoned. Six patients underwent simultaneous new AVF creation, 4 ipsilateral, and 2 contralateral. None of the patients developed symptomatic steal syndrome or congestive heart failure. Five of 6 patients had successful usage of the new AVF, and subsequently underwent ligation and excision of the aneurysmal AVF, thus avoiding a temporary HDC. Close monitoring for skin compromise and bleeding in the aneurysmal AVF is recommended while the new AVF matures. Copyright © 2018 Elsevier Inc. All rights reserved.

Enterovaginal or Vesicovaginal Fistula Control Using a Silicone Cup.

Russell, Katie W; Robinson, Ryan E; Mone, Mary C; Scaife, Courtney L

2016-12-01

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

Background and Objectives Squamous cell carcinoma is the most common pathological type among the cancers of the larynx. Standard treatment for squamous cell carcinoma of the larynx is the combination of chemotherapy, radiotherapy, and laryngectomy. Pharyngocutaneous fistula is a common complication of laryngectomy. We hypothesized that decellularized and lyophilized human amnion/chorion membrane can be an effective, non‐invasive method of treating pharyngocutaneous fistula. Methods A total of 67 patients with laryngeal squamous cell carcinoma were retrospectively analyzed after treatment in a prospective trial. After preoperative chemotherapy, radiotherapy, and total or extended laryngectomy, primary wound healing occurred in 42 (62.7%) patients. Pharyngocutaneous fistula developed in 8 (11.9%) patients. Decellularized and lyophilized human amnion/chorion membrane grafts were used to reconstruct the fistulas. Results The average time for the full healing of the wound in all patients after transplantation of these grafts was 18 days. Conclusion The advantages of using these grafts over other existing methods of pharyngocutaneous fistula treatment are that they are non‐invasive, prevent donor morbidity, and enable management of the wound without using classical wound gauze.

Duodenal injury is a serious abdominal organ injury. Duodenal fistula is one of the most serious complications in gastrointestinal surgery, which is concerned for its critical status, difficulty in treatment and high mortality. Thoracic and abdominal compound closed injury and a small part of open injury are common causes of duodenal injury. Iatrogenic or traumatic injury, malnutrition, cancer, tuberculosis, Crohn's disease etc. are common causes of duodenal fistula, however, there has been still lacking of ideal diagnosis and treatment by now. The primary treatment strategy of duodenal fistula is to determine the cause of disease and its key point is prevention, including perioperative parenteral and enteral nutrition support, improvement of hypoproteinemia actively, avoidance of stump ischemia by excessive separate duodenum intraoperatively, performance of appropriate duodenum stump suture to ensure the stump blood supply, and avoidance of postoperative input loop obstruction, postoperative stump bleeding or hematoma etc. Once duodenal fistula occurs, a simple and reasonable operation can be selected and performed after fluid prohibition, parenteral and enteral nutrition, acid suppression, enzyme inhibition, anti-infective treatment and maintaining water salt electrolyte and acid-base balance. Double tube method, duodenal decompression and peritoneal drainage can reduce duodenal fistula-related complications, and then reduce the mortality, which can save the lives of patients.

Transsphincteric fistulotomy is associated with a variable degree of fecal incontinence that is directly related to the thickness of the sphincter mechanism overlying the fistula. Staged fistulotomy with seton or the use of cutting seton designed to reduce the proportionate incontinence rates have failed to do so. This has resulted in attempts to find novel sphincter-sparing techniques in the past 2 decades including draining seton, fibrin sealant, anal fistula plug, dermal advancement, and endorectal advancement flaps. These operations have a variable success rates of 30% to 80% reported in the literature. In 2007, Rojanasakul from Thailand demonstrated a novel technique, ligation of intersphincteric fistula tract, and reported a 94% success rate in a small series. Since then, a few other small cohorts of patients have been reported in the literature with success rates varying from 57% to 82%. An institutional review board-approved study was proposed to measure our results and compare them with the published data. This study was undertaken to evaluate the success of ligation of intersphincteric fistula tract procedures in a group of unselected transsphincteric fistulas deemed unsuitable for lay-open fistulotomy. The procedure was performed in 3 different settings: a public institution, a major university hospital, and a large private hospital. A total of 40 patients underwent 41 ligation of intersphincteric fistula tract procedures performed by 6 Board-certified colon and rectal surgeons. In a mean follow-up of 18 weeks, 74% of the patients achieved healing. In patients who underwent ligation of intersphincteric fistula tract as their primary procedure, the healing rate was 90%. The limitation of this study is its "case series" nature and the short mean follow-up period of 18 weeks. Ligation of intersphincteric fistula tract has had excellent success in transsphincteric fistulas in multiple small series. A larger number of patients and longer follow-up period are needed to validate the early favorable results.

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

Laser soldering technique for sutureless urethral surgery.

Investigators have attempted sutureless surgery to decrease operative time, lessen the inflammatory response, maintain luminal continuity, and increase the ease of performing technically difficult surgery. Only recently has laser-tissue welding (LTW) been used for urologic reconstruction in humans. Herein, we present our technique of laser soldering with the half-watt diode laser and wavelength matched albumin-based solder. Our methodology of LTW relies on bonding between the outer surface of the wound edges and the solder. The 808-nm diode wavelength does not penetrate deep tissue, and thus relies on indocyanine green dye to localize photon absorption. Since 1994, we have performed LTW, as an adjunct to suturing (N = 25) and as a primary means of tissue closure (N = 11). Preoperative diagnoses included hypospadias, urethral stricture, urethral diverticulum, and urethral fistulae. Follow-up ranged between 3 months and 3 years to identify complications of wound healing, stricture, and fistula formation. In the 37 patients undergoing urethral surgery, no strictures or diverticula have resulted. None of the patients have had wound infections or poor wound healing. Overall, five patients have developed fistulas between 2 weeks and 6 months postoperatively. The location of the hypospadiac meatus was scrotal or penoscrotal in four of these patients. Two fistulas developed following sutureless urethroplasty (reoperative) after traumatic catheterization for urinary retention (one case for inadvertent catheter removal). In our initial experience, the overall complication rate using laser soldering was 19% compared to 24% in an historical control group. Half of the complications occurred in a reoperative situation. More recently, the overall fistula rate was 14%; however, for primary cases, the current fistula rate is only 6%. LTW is safe and easy to perform. The application of protein solders (+/-chromophores) have permitted far greater tensile strengths to be achieved than laser alone. Temperature-control and chromophore-control have permitted safety and efficacy to be achieved. Solder application site and technique are equally important in the success of the LTW process. A randomized, prospective study comparing LTW to suturing is ongoing.

Although urethral covering during hypospadias repair minimizes the incidence of fistula, wide variation in results among surgeons has been reported. To investigate what type of flap used during Snodgrass or fistula repair reduces the incidence of fistula occurrence. We systematically reviewed published results for urethral covering during Snodgrass and fistula repair procedures. An initial online search detected 1740 reports. After exclusion of ineligible studies at two stages, we included all patients with clear data on the covering technique used (dartos fascia [DF] vs tunica vaginalis flap [TVF]) and the incidence of postoperative fistula. A total of 51 reports were identified involving 4550 patients, including 33 series on DF use, 11 series on TVF use, and seven retrospective comparative studies. For distal hypospadias, double-layer DF had the lowest rate of fistula incidence when compared to single-layer DF (5/855 [0.6%] vs 156/3077 [5.1%]; p=0.004) and TVF (5/244, 2.0%), while the incidence was highest for single-layer DF among proximal hypospadias cases (9/102, 8.8%). Among repeat cases, fistula incidence was significantly lower for TVF (3/47, 6.4%) than for DF (26/140, 18.6%; p=0.020). Among patients with fistula after primary repair, the incidence of recurrence was 12.2% (11/90) after DF and 5.1% (5/97) after TVF (p=0.39). The absence of a minimum follow-up time and the lack of information regarding skin complications and rates of urethral stricture are limitations of this study. A double DF during tubularized incised plate urethroplasty should be considered for all patients with distal hypospadias. In proximal, repeat, and fistula repair cases, TVF should be the first choice. On the basis of these findings, we propose an evidence-based algorithm for surgeons who are still in their learning phase or want to improve their results. We systematically reviewed the impact of urethral covering in reducing fistula formation after hypospadias repair. We propose an algorithm that might help to maximize success rates for tubularized incised plate urethroplasty. Copyright © 2016 European Association of Urology. Published by Elsevier B.V.

Current practices in treatment of female genital fistula: a cross sectional study.

Maternal outcomes in most countries of the developed world are good. However, in many developing/resource-poor countries, maternal outcomes are bleaker: Every year, more than 500,000 women die in childbirth, mostly in resource-poor countries. Those who survive often suffer from severe and long-term morbidities. One of the most devastating injuries is obstetric fistula, occurring most often in south Asia and sub-Saharan Africa. Fistula treatment and care are available in many countries across Africa and Asia, but there is a lack of reliable data around clinical factors associated with the success of fistula repair surgery. Most published research has been retrospective. While these studies have provided useful information about the care and treatment of fistula, they are limited by the design. This study was designed to identify practices in care that could lead to the design of prospective and randomized controlled trials. Self-administered questionnaires were completed by 40 surgeons known to provide fistula treatment services in Africa and Asia at private and government hospitals. The questionnaire was divided into three parts to address the following issues: prophylactic use of antibiotics before, during, and after fistula surgery; urethral catheter management; and management practices for patients with urinary incontinence following fistula repair. The results provide a glimpse into current practices in fistula treatment and care across a wide swath of geographic, economic, and organizational considerations. There is consensus in treatment in some areas (routine use of prophylactic antibiotics, limited bed rest until the catheter is removed, nonsurgical treatment for postsurgical incontinence), while there are wide variations in practice in other areas (duration of catheter use, surgical treatments for postsurgical incontinence). These findings are based on a small sample and do not allow for recommending changes in clinical care, but they point to issues for possible clinical trial research that would contribute to more efficient and effective fistula care. The findings from the survey allowed us to consider clinical practices most influential in the cost, efficacy, and safety of fistula treatment. These considerations led us to formulate recommendations for eight randomized controlled trials on the following subjects: 1) Efficacy/safety of short-term catheterization; 2) efficacy of surgical and nonsurgical therapies for urinary incontinence; 3) technical measures during fistula repair to reduce the incidence of post-surgery incontinence; 4) identification of predictive factors for "incurable fistula"; 5) usefulness of urodynamic studies in the management of urinary incontinence; 6) incidence and significance of multi-drug resistant bacteria in the fistula population; 7) primary management of small, new fistulas by catheter drainage; and 8) antibiotic prophylaxis in fistula repair.

Vaginal calculi are rarely encountered and are often misdiagnosed as bladder calculi because of the difficulty in achieving an appropriate diagnosis. Most vaginal calculi result from the presence of a urethrovaginal fistula; those occurring in the absence of such fistulas are extremely rare. We present a case of a 42-year-old bedridden woman with mental and physical disabilities who had been misdiagnosed for a decade as having a bladder calculus. We removed the calculus nonsurgically and the analyzed the components. Results demonstrated the presence of a primary vaginal calculus. Vaginal calculi may occasionally occur in disabled women, but further investigation of the etiology of such calculi is required.

Female genital fistula is a devastating maternal complication of delivery in developing countries. We sought to analyse the incidence and proportion of fistula recurrence, residual urinary incontinence, and pregnancy after successful fistula closure in Guinea, and describe the delivery-associated maternal and child health outcomes. We did a longitudinal study in women discharged with a closed fistula from three repair hospitals supported by EngenderHealth in Guinea. We recruited women retrospectively (via medical record review) and prospectively at hospital discharge. We used Kaplan-Meier methods to analyse the cumulative incidence, incidence proportion, and incidence ratio of fistula recurrence, associated outcomes, and pregnancy after successful fistula closure. The primary outcome was recurrence of fistula following discharge from repair hospital in all eligible women who consented to inclusion and could provide follow-up data. 481 women eligible for analysis were identified retrospectively (from Jan 1, 2012, to Dec 31, 2014; 348 women) or prospectively (Jan 1 to June 20, 2015; 133 women), and followed up until June 30, 2016. Median follow-up was 28·0 months (IQR 14·6-36·6). 73 recurrent fistulas occurred, corresponding to a cumulative incidence of 71 per 1000 person-years (95% CI 56·5-89·3) and an incidence proportion of 18·4% (14·8-22·8). In 447 women who were continent at hospital discharge, we recorded 24 cases of post-repair residual urinary incontinence, equivalent to a cumulative incidence of 23·1 per 1000 person-years (14·0-36·2), and corresponding to 10·3% (5·2-19·6). In 305 women at risk of pregnancy, the cumulative incidence of pregnancy was 106·0 per 1000 person-years, corresponding to 28·4% (22·8-35·0) of these women. Of 50 women who had delivered by the time of follow-up, only nine delivered by elective caesarean section. There were 12 stillbirths, seven delivery-related fistula recurrences, and one maternal death. Recurrence of female genital fistula and adverse pregnancy-related maternal and child health outcomes were frequent in women after fistula repair in Guinea. Interventions are needed to safeguard the health of women after fistula repair.

To perform a retrospective study on the experience of the Clinic of General, Liver, Biliary and Pancreatic Surgery, Alexandrovska Hospital in the diagnosis and treatment of patients with acquired entero-cutaneus fistulas and to analyse the early postoperative results. We treated 24 patients with postoperative entero-cutaneous fistulas in the period Jan., 2000 - Aug., 2004. The male sex and the age above 50 were dominent. The primary disease was of oncological origin in 22 cases (91.66%). Anemia, hypoprotenemia and hypoalbuminemia were predisposing and risk factors in 19 cases (79.17%). Fistulography was routinely used for establishing the diagnosis. Surgical treatment was received by all the 6 patients (100%) with small bowel fistulas and by 15 from the 18 patients with large bowel fistulas (83.33%). EARLY POSTOPERATIVE RESULTS: The mortality rate was 4.54% (1 fatal outcome from 22 operated patients). The morbidity rate was 36,36% (8 cases) but none of the complications needed a reoperation. 1. The most frequent causal factor for entero-cutaneus fistulas in our material was an anastomotic leakige after bowel resection (95.83%); 2. The risk for such a coplication is higher in cancer patients with other predisposing pathological factors; 3. From the pahtological and clinical point of view the entero-cutaneus fistulas caused significant disturbances in base-alkaline and electrolyte balance, malnutrition and cahexia; 4. The clinical signs and the fistulography prooved to be reliable diagnostic methods; 5. The preoperative substitution and nutritional therapy had a significant benefit on the postoperative results, especially in cases of small bowel fistulas; 6. The open surgery was the main therapeutical method in the complex treatment of those patients.

Postoperative pancreatic fistula is the most common and potentially life-threatening complication after pancreatic surgery. Although nutritional support is a key component of conservative therapy in such cases, there have been no well-designed clinical trials substantiating the superiority of either total parenteral nutrition or enteral nutrition. This study was conducted to compare the efficacy and safety of both routes of nutritional intervention. A randomized clinical trial was conducted in a tertiary surgical center of pancreatic and gastrointestinal surgery. Seventy-eight patients with postoperative pancreatic fistula were treated conservatively and randomly assigned to groups receiving for 30 days either enteral nutrition or total parenteral nutrition. The primary end point was the 30-day fistula closure rate. After 30 days, closure rates in patients receiving enteral and parenteral nutrition were 60% (24 of 40) and 37% (14 of 38), respectively (P=.043). The odds ratio for the probability that fistula closes on enteral nutrition compared to total parenteral nutrition was 2.571 (95% confidence interval [CI]: 1.031-6.411). Median time to closure was 27 days (95% CI: 21-33) for enteral nutrition, and no median time was reached in total parenteral nutrition (P=.047). A logistic regression analysis identified only 2 factors significantly associated with fistula closure, ie, enteral nutrition (odds ratio=6.136; 95% CI: 1.204-41.623; P=.043) and initial fistula output of ≤200 mL/day (odds ratio=12.701; 95% CI: 9.102-47.241; P<.001). Enteral nutrition is associated with significantly higher closure rates and shorter time to closure of postoperative pancreatic fistula. Copyright © 2011 AGA Institute. Published by Elsevier Inc.

To evaluate the safety and efficacy of arteriovenous fistula (AVF) creation with a thermal resistance anastomosis device (TRAD). From January 2014 to March 2015, 26 patients underwent ultrasound (US)-guided percutaneous creation of proximal radial artery-to-perforating vein AVFs with a TRAD that uses heat and pressure to create a fused anastomosis. Primary endpoints were fistula creation, patent fistula by Doppler US, two-needle dialysis at the prescribed rate, and device-related complications. Technical success rate of fistula creation was 88% (23 of 26). Procedure time averaged 18.4 minutes (range, 5-34 min), and 96% of anastomoses (22 of 23) were fused. At 6 weeks, 87% of AVFs (20 of 23) were patent, 61% (14 of 23) had 400-mL/min brachial artery flow, 1 patient was receiving dialysis, 2 fistulae had thrombosed, and 1 patient had died unrelated to the procedure. Eighty percent (16 of 20), 70% (14 of 20), and 60% (12 of 20) of patients were receiving dialysis at 3, 6, and 12 months; 4 patients died, 3 fistulae failed, and one patient was lost to follow-up. Overall, 87% of AVFs (20 of 23) had an additional procedure at a mean of 56 days (range, 0-239 d), including balloon dilation in 43% (n = 10), brachial vein embolization in 26% (n = 6), basilic vein ligation in 17% (n = 4), venous transposition in 30% (n = 7), and valvulotomy in 4% (n = 1). There were no major complications related to the device. Percutaneous AVFs created with a TRAD met the safety endpoints of this study. Midterm follow-up demonstrated intact anastomoses and fistulae suitable for dialysis. Copyright © 2016 SIR. Published by Elsevier Inc. All rights reserved.

Dural arteriovenous fistula (DAVF) is a rare type of cerebral arteriovenous malformation. Common presenting symptoms are related to hemorrhage. However, rarely these patients may present with myelopathy. We present two cases of DAVF presenting as rapidly progressive myelopathy. Two treatment options are available: microsurgical interruption of the fistula and endovascular embolization. These treatment options of DAVFs have improved significantly in the last decade. The optimal treatment of DAVFs remains controversial, and there is an ongoing debate as to whether primary endovascular or primary microsurgical treatment is the optimal management for these lesions. However, despite treatment a high percentage of patients are still left with severe disability. The potential for functional ambulation in patients with DAVF is related to the time of intervention. This emphasizes the important of early diagnosis and early intervention in DAVF. The eventual outcome may depend on several factors, such as the duration of symptoms, the degree of disability before treatment, and the success of the initial procedure to close the fistula. The usage of magnetic resonance imaging and selective angiography has significantly improved the ability to characterize DAVFs, however, these lesions remain inefficiently diagnosed. If intervention is delayed even prolonged time in rehabilitation does not change the grave prognosis. This review outlines the presentation, classication and management of DAVF as well as discussing patient outcomes. PMID:25516869

The Relationship Between Neutrophil–Lymphocyte Ratio and Primary Patency of Percutaneous Transluminal Angioplasty in Hemodialysis Arteriovenous Fistula Stenosis When Using Conventional and Drug-Eluting Balloons

ObjectiveThe aim of this study is to investigate the potential association of neutrophil–lymphocyte ratio (NLR) between primary patency of percutaneous transluminal angioplasty (PTA) in hemodialysis arteriovenous fistula stenosis and type (Conventional and Drug-Eluting) of balloons used in PTA.Material-MethodThis retrospective study consists of 78 patients with significant arteriovenous fistulas stenosis who were treated with PTA by using Drug-Eluting Balloon (DEB) (n = 29) or Conventional Balloon (CB) (n = 49). NLR was calculated from preinterventional blood samples. All patients were classified into two groups. Group A; primary patency <12 months (43/78), Group B; primary patency ≥12 months (35/78). Cox regression analysis and Kaplan–Meier method were used to determine respectivelymore » independent factors affecting the primary patency and to compare the primary patency for the two balloon types.ResultsNLR ratio and balloon type of the two groups were significantly different (p = 0.002, p = 0.010). The cut-off value of NLR was 3.18 for determination of primary patency, with sensitivity of 81.4 % and specificity of 51.4 %. Primary patency rates between PTA with DEB and CB displayed statistically significant differences (p < 0.05). The cut-off value was 3.28 for determination of 12-month primary patency with the conventional balloon group; sensitivity was 81.8 % and specificity was 81.3 %. There was no statistical relation between NLR levels and the drug-eluting balloon group in 12-month primary patency (p = 0.927).ConclusionIncreased level of NLR may be a risk factor in the development of early AVF restenosis after successful PTA. Preferring Drug-Eluting Balloon at an increased level of NLR can be beneficial to prolong patency.« less

The arteriovenous fistula (AVF) is the preferred hemodialysis access type because it has better patency rates and fewer complications than other access types. However, primary failure remains a common problem impeding AVF maturation and adding to patients' morbidity and mortality. Juxta-anastomotic (or inflow) stenosis is the most common reason leading to primary failure, and percutaneous transluminal angioplasty continues to be the gold-standard treatment with excellent success rates. Intimal hyperplasia (IH) has been traditionally blamed as the main pathophysiologic culprit, but new evidence raises doubts regarding the contribution of IH alone to primary failure. We report a 64-year-old man with a 2-stage brachiobasilic AVF that was complicated by failure 4 months after creation. An angiogram showed multiple juxta-anastomotic and midfistula stenotic lesions. Percutaneous transluminal angioplasty was successful in assisting maturation and subsequently cannulating the AVF for hemodialysis treatment. We failed to identify the underlying cause of stenosis because biopsy specimens from fistula tissue obtained at the time of transposition revealed no occlusive IH. This case emphasizes the need for additional research on factors contributing to AVF failure besides IH and highlights the need for more therapeutic options to reduce AVF failure rate.

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-twomore » 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.« less

Post-traumatic urethral damage resulting in urethrovaginal fistulas or strictures, though rare, should be suspected in patients who have unexpected urinary incontinence or lower urinary tract symptoms after pelvic surgery, pelvic fracture, a long-term indwelling urethral catheter, or pelvic radiation. Careful physical examination and cystourethroscopy are critical to diagnose and assess the extent of the fistula. A concomitant vesicovaginal or ureterovaginal fistula should also be ruled out. The two main indications for reconstruction are sphincteric incontinence and urethral obstruction. Surgical correction intends to create a continent urethra that permits volitional, painless, and unobstructed passage of urine. An autologous pubovaginal sling, with or without a Martius flap at time of reconstruction, should be considered. The three approaches to urethral reconstruction are anterior bladder flaps, posterior bladder flaps, and vaginal wall flaps. We believe vaginal flaps are usually the best option. Options for vaginal repair of fistula include primary closure, peninsula flaps, bilateral labial pedicle flaps, and labial island flaps. Outcomes are optimized by using exacting surgical principles during repair and careful postoperative management by an experienced reconstructive surgeon.

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 wasmore » 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.« less

Formal preoperative ultrasound (US) mapping of vascular anatomy by radiology is recommended before hemodialysis access surgery. We hypothesized that US performed by general surgery residents in place of formal US would decrease the time from initial consult to creation of dialysis access without affecting patient outcomes. This is a retrospective review of all patients who underwent dialysis access surgery from November 2014 to July 2016 and received preoperative upper extremity US vein and artery evaluation by either radiology or general surgery residents. The primary endpoints were days from initial consult to dialysis access creation, rate of arteriovenous fistula (AVF) creation, fistula maturation, and 1-year primary assisted patency. Of 242 patients, 167 (69%) had formal US, and 75 (31%) had only a resident US. The resident US group had 100% AVF creation compared with the formal US group with 92.2% AVF creation (P = 0.01). There was no difference between the groups in rate of fistula maturation (P = 0.1) and 1-year assisted patency (P = 0.9). Of the resident US 90.7% occurred in the outpatient setting. On multivariable analysis controlling for outpatient consult, the average time to the operating room was 13.7 days longer for the formal US group in the outpatient setting (P = 0.0006). Ultrasound vein and artery evaluation at the time of the initial consult by general surgery residents can decrease the time to dialysis access creation by bypassing the need for formal US with a higher rate of AVF creation and no difference in fistula maturation or 1-year primary assisted patency.

Hemodialysis vascular access recommendations promote arteriovenous (AV) fistulas first; however, it may not be the best approach for all hemodialysis patients, because likelihood of successful fistula placement, procedure-related and subsequent costs, and patient survival modify the optimal access choice. We performed a decision analysis evaluating AV fistula, AV graft, and central venous catheter (CVC) strategies for patients initiating hemodialysis with a CVC, a scenario occurring in over 70% of United States dialysis patients. A decision tree model was constructed to reflect progression from hemodialysis initiation. Patients were classified into one of three vascular access choices: maintain CVC, attempt fistula, or attempt graft. We explicitly modeled probabilities of primary and secondary patency for each access type, with success modified by age, sex, and diabetes. Access-specific mortality was incorporated using preexisting cohort data, including terms for age, sex, and diabetes. Costs were ascertained from the 2010 USRDS report and Medicare for procedure costs. An AV fistula attempt strategy was found to be superior to AV grafts and CVCs in regard to mortality and cost for the majority of patient characteristic combinations, especially younger men without diabetes. Women with diabetes and elderly men with diabetes had similar outcomes, regardless of access type. Overall, the advantages of an AV fistula attempt strategy lessened considerably among older patients, particularly women with diabetes, reflecting the effect of lower AV fistula success rates and lower life expectancy. These results suggest that vascular access-related outcomes may be optimized by considering individual patient characteristics. Copyright © 2015 by the American Society of Nephrology.

Redo esophageal surgery: the diagnosis and management of recurrent tracheoesophageal fistula.

PubMed

Coran, Arnold G

2013-10-01

This article presents a 30-year review of 38 recurrent tracheoesophageal fistulas. The initial 26 cases were presented in 2009 at the annual meeting of the British Association of Pediatric Surgeons and the European Association of Pediatric Surgeons Joint Conference and published in the Journal of Pediatric Surgery (Bruchet al. J Pediatr Surg 45:337-340, 2010). In the initial cohort of 26 patients, 18 had a leak after their primary operation and 22 had respiratory symptoms leading to the discovery of the recurrent fistula. The diagnosis was made by a contrast study in 24. The repairs entailed replacing a catheter through the fistula, separating the trachea and esophagus completely using sharp dissection and placing vascularized tissue, either pleura or pericardium between the suture lines. Postoperative complications included seven anastomotic leaks, four strictures and three recurrent fistulas. Long-term follow-up (median of 84 months) showed that 21 took all of their nutrition by mouth, three were tube fed and two required a combination of both. Of the 23 patients with growth chart data, 16 fell into the first quartile of the growth chart, whereas none fell between the 75th and 100th percentile. In conclusion, this initial series of 26 patients along with the updated additional series of 12 patients is the largest series thus far reported in the literature. All 38 patients represent the characteristics of recurrent tracheoesophageal fistulas, including techniques to make the diagnosis and to provide a secure closure of the fistula, and the long-term outcomes of these patients.

To evaluate the effect of percutaneous transluminal angioplasty (PTA) on haemodialysis fistulas utilising drug-coated balloons with plain balloon vessel preparation (DCB). In the study group, 31 patients (16 men; mean age 62.8 ± 17.2 years) with failing arteriovenous fistulas were treated, with DCB, and compared with a control group (31 patients; 15 men; mean age 67.0 ± 8.44 years), in which only plain balloon PTA was performed. All stenoses were dilated with regular PTA balloons. After achieving haemodynamic success (< 30% residual stenosis), drug-coated balloons were used for drug administration in the study group. The follow-up intervals were 6, 12 and 24 months. Target lesion primary patency, primary assisted patency and secondary patency were compared. The statistical significance was set at 0.05. Target lesion primary patency was compared in both groups and was significantly higher in the study group (DCB) at 6 months (90.3 vs. 61.3%; p = 0.016), 12 months (77.4 vs. 29%; p = 0.0004) as well as 24 months (45.2 vs. 16.1%; p = 0.026). Kaplan-Meier survival curves also showed a significant difference for target lesion primary patency (534.2 vs. 315.7 days; p = 0.0004). There were no significant differences in target lesion primary assisted patency and in secondary patency. However, only 38.7% of patients in the study group were treated twice or more versus 80.6% in the control group (p = 0.002). DCB increases target lesion primary patency during the first 24 months and decreases the rate of reinterventions.

High-intensity focused ultrasound can be used for the primary treatment of prostate cancer and biochemical recurrence after radical prostatectomy or radiation. Complications of high-intensity focused ultrasound include urinary retention, urethral stenosis, stress incontinence, urinary tract infections, dysuria, impotence, and rarely, rectourethral or rectovesicular fistula. We describe a patient presenting with urinary retention, urinary tract infections and intermittent stress incontinence, later found to be associated with pubic bone osteomyelitis stemming from a prostatopubic fistula.

Sinister undesirable pathologies often accompany malignancies. Though the entire emphasis is on cancer management, these benign conditions are more life-threatening than the primary malignancy itself. We report an interesting imaging finding of broncho-esophageal fistula leading to lung abscess on (18)F- fluoro-deoxy-glucose positron emission tomography/computed tomography (FDG PET/CT) in large middle esophageal cancer, which due to early detection, was promptly managed.

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.

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 themore » 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.« less

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.

Obstetric fistula and sociocultural practices in Hausa community of Northern Nigeria.

Obstetric Fistula is a childbirth injury that disproportionately affects women in sub-Saharan Africa. Although poverty plays an important role in perpetuating obstetric fistula, sociocultural practices has a significant influence on susceptibility to the condition. This paper aims to explore narratives in the literature on obstetric fistula in the context of Hausa ethno-lingual community of Northern Nigeria and the potential role of nurses and midwives in addressing obstetric fistula. Three major cultural practices predispose Hausa women to obstetric fistula: early marriages and early child bearing; unskilled birth attendance and female circumcision and sociocultural constraints to healthcare access for women during childbirth. There is a failure to implement the International rights of the girl child in Nigeria which makes early child marriage persist. The Hausa tradition constrains the decision making power of women for seeking health care during childbirth. In addition, there is a shortage of nurses and midwives to provide healthcare service to women during childbirth. To improve health access for women, there is a need to increase political commitment and budget for health human resource distribution to underserved areas in the Hausa community. There is also a need to advance power and voice of women to resist oppressive traditions and to provide them with empowerment opportunities to improve their social status. The practice of traditional birth attendants can be regulated and the primary health care services strengthened. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd.

Endoscopic control of enterocutaneous fistula by dual intussuscepting stent technique.

Large high-output enterocutaneous fistulas pose great difficulties, especially in the setting of recent surgery and compromised skin integrity. This video demonstrates a new technique of endoscopic control of enterocutaneous fistula by using two covered overlapping stents. In brief, the two stents are each inserted endoscopically, one proximal, and the other distal to the fistula with 2 cm of each stent protruding cutaneously. Following this, the proximal stent is crimped and intussuscepted into the distal stent with an adequate overlap. A prolene suture is passed through the anterior wall of both stents to prevent migration. The two stents used were evolution esophageal stents-10 cm long, fully covered, double-flared with non-flared and flared diameters being 20 and 25 mm, respectively (product number EVO-FC-20-25-10-E, Cook Medical, Bloomington, IN, USA). The patient featured in this video developed a high-output enterocutaneous fistula proximal to a loop ileostomy, which was created following a small bowel leak after a curative surgery for bladder cancer. Using the technique featured in this video (schematic depicted in Fig. 1), the patient was nutritionally optimized with oral feeds from albumin of 0.9-3.4 g/dl within 2 months despite prior failure to achieve nutrition optimization and adequate skin protection with combination of oral and/or parenteral nutrition. Three months after stenting, following nutritional optimization and improvement of skin coverage, definitive procedure consisted of uncomplicated fistula resection with primary stapled side-to-side functional end-to-end anastomosis. The stents were not completely incorporated into the mucosa and were rather easily pulled through the residual fistula opening just prior to the surgery. Only minimal fibrosis was noted and less than 20 cm of involved small bowel needed to be resected. Had the fistula have closed completely, the options would have included (1) proceeding to bowel resection with removal of the stents regardless of closure, or (2) cutting the securing prolene stitch and observation. Considering the placement of the stents in mid-small bowel, their endoscopic retrieval would have been difficult unless they were to migrate into the colon. Although a prior attempt at managing an enterocutaneous fistula with a stent deployed through a colostomy site was previously reported [1], there is no published account of bridging an enterocutaneous fistula with overlapping endoscopic stents through the fistula itself. This video serves as a proof of concept for temporizing enterocutaneous fistulas with endoscopic stenting.

Complex perirectal sepsis: clinical classification and imaging.

2006-07-01

The use of specialized imaging to assess cryptogenic fistula-in-ano is selective, aimed at delineation of the site of the internal fistula opening and the relationship of the primary and secondary tracks and collections to the main levator plate. Advanced imaging also permits definition of the destructive effects of perirectal sepsis (e.g. internal or external anal sphincter damage, perineal body destruction and an ano- or rectovaginal fistula), which may require secondary reconstructive surgery. We performed a PubMed search of outcomes for fistula management in the English and non-English literature, and summarized results regarding the accuracy of internal opening and horseshoe detection as well as the operative correlation for cryptogenic and non-cryptogenic fistula-in-ano using endoanal ultrasound (EAUS) and magnetic resonance (MR) imaging. Only literature defining these characteristics was included. The advantages and limitations of the main forms of imaging are discussed in this review with emphasis on EAUS and endoanal or pelvic phased-array MR fistulography. The new technique of transperineal sonography is highlighted. A small but important group of patients with complex fistula-in-ano require specialized imaging. There are specific limitations of endoanal ultrasound (EAUS) which necessitate pelvic phased-array MR imaging. Initial work suggests that EAUS may have a role in intraoperative use for image-guided drainage of recurrent abscesses where operative interpretation can be difficult. The coloproctologist in a tertiary referral center must acquire the skills of ultrasound performance in order to successfully treat fistulous disease, suggesting a role for formal imaging accreditation as part of coloproctological training. Future studies should determine both what sequential imaging algorithms for imaging are cost-effective as well as predictive of fistula cure.

Isolated segmental, sectoral and right hepatic bile duct injuries

The treatment of isolated segmental, sectoral and right hepatic bile duct injuries is controversial. Nineteen patients were treated over a 26-year period. Group one was comprised of 4 patients in whom the injury was primarily repaired during the original surgery; 3 over a T-tube, 1 with a Roux-en-Y. These patients had an uneventful recovery. The second group consisted of 5 patients in whom the duct was ligated; 4 developed infection, 3 of which required drainage and biliary repair. Two patients had good long-term outcomes; the third developed a late anastomotic stricture requiring further surgery. The fourth patient developed a small bile leak and pain which resolved spontaneously. The fifth patient developed complications from which he died. The third group was comprised of 4 patients referred with biliary peritonitis; all underwent drainage and lavage, and developed biliary fistulae, 3 of which resolved spontaneously, 1 required Roux-en-Y repair, with favorable outcomes. The fourth group consisted of 6 patients with biliary fistulae. Two patients, both with an 8-wk history of a fistula, underwent Roux-en-Y repair. Two others also underwent a Roux-en-Y repair, as their fistulae showed no signs of closure. The remaining 2 patients had spontaneous closure of their biliary fistulae. A primary repair is a reasonable alternative to ligature of injured duct. Patients with ligated ducts may develop complications. Infected ducts require further surgery. Patients with biliary peritonitis must be treated with drainage and lavage. There is a 50% chance that a biliary fistula will close spontaneously. In cases where the biliary fistula does not close within 6 to 8 wk, a Roux-en-Y anastomosis should be considered. PMID:19322912

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 endovascularmore » 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. Patients with cancer may only need treatment for the acute bleeding episode, and an endovascular approach has the advantage of low morbidity.« less

Background Post-intubation tracheoesophageal fistula (PITEF) is an often mistreated, severe condition. This case series reviewed for both the choice and timing of surgical technique and outcome PITEF patients. Methods This case series reviewed ten consecutive patients who had undergone esophageal defect repair and airway resection/reconstruction between 2000 and 2014. All cases were examined for patients: general condition, medical history, preparation to surgery, diagnostic work-up, timing of surgery and procedure, fistula size and site, ventilation type, nutrition, post-operative course and complications. Results All patients were treated according to Grillo’s technique. Overall, 6/10 patients had undergone a preliminary period of medical preparation. Additionally, 3 patients had already had a tracheostomy, one had had a gastrostomy and 4 had both. One patient had a Dumon stent with enlargement of the fistula. Concomitant tracheal stenosis had been found in 7 patients. The mean length of the fistulas was 20.5 mm (median 17.5 mm; range, 8–45 mm), at a median distance from the glottis of 43 mm (range, 20–68 mm). Tracheal resection was performed in all ten cases. The fistula was included in the resection in 6 patients, while it was excluded in the remaining 4 due to their distance. Post-repair tracheotomy was performed in 3 patients. The procedure was performed in 2 ventilated patients. Morbidity related to fistula and anastomosis was recorded in 3 patients (30%), with one postoperative death (10%); T-Tube placement was necessary in 3 patients, with 2/3 decannulations after long-stenting. Definitive PITEF closure was obtained for all patients. At 5-year follow-up, the 9 surviving patients had no fistula-related morbidity. Conclusions Primary esophageal closure with tracheal resection/reconstruction seemed to be effective treatment both short and long-term. Systemic conditions, mechanical ventilation, detailed preoperative assessment and appropriate preparation were associated with outcome. Indeed, the 3 patients who had received T-Tube recovered from anastomotic complications. PMID:28275475

The entero-cutaneous fistulas (ECF) are abnormal communications between intestine and abdominal skin. They can occur spontaneously, or after an injury or a surgical procedure. They are associated with a high rate of morbidity and mortality. Spontaneous fistulas can mainly occur in patients affected by cancer, inflammatory bowel disease, diverticulitis, appendicitis, as a result of radiotherapy or injuries. Surgical procedures, carried out in case of neoplastic diseases, inflammatory bowel disease, adhesions removal, represent the primary cause in the development of a postoperative fistulas. Malnourishment, poor general conditions of the patient, high output fistula along with anatomical site of development, and the presence of abscesses, represent the negative factors influencing the spontaneous healing of fistulas. The experience reported here is about three ECF cases occurred after surgery and treated only with medical therapy. The first case is a woman in good general conditions who underwent surgery to remove a recurrent retroperitoneal myxoid liposarcoma situated in the right lower quadrant. The patient had never undergone surgery for an intestinal resection. The other two patients analyzed were affected by sepsis and metabolic unbalance and had developed a fistula after colonic resection. Fluids and electrolytes adjustments and sepsis management have preceded any other kind of therapy. Continuous infusion with somatostatin, fast, proton pump inhibitors and loperamide have been taken up to decrease secretions and intestinal motility. Total parenteral nutrition has been essential to recover nutritional status and improve patients' general conditions. In order to heal and protect peri-fistula skin we have used sterile washing solutions, absorbable ionic exchange resin, silver and polyurethanes based medications and colostomy bags adhesive systems. Since surgical treatment of ECF is associated with high rates of morbidity and mortality, conservative treatment should always be taken into consideration. When conservative treatment fails, delayed surgical intervention has been related to a higher rate of success. The purpose of this study is to describe diagnostic and therapeutic guidelines to general surgeons, like ourselves, whenever they have to deal with ECF cases.

Background: One of the mandates of the Canadian Society of Nephrology’s (CSN) Vascular Access Working Group (VAWG) is to inform the nephrology community of the current status of vascular access (VA) practice within Canada. To better understand VA practice patterns across Canada, the CSN VAWG conducted a national survey. Objectives: (1) To inform on VA practice patterns, including fistula creation and maintenance, within Canada. (2) To determine the degree of consensus among Canadian clinicians regarding patient suitability for fistula creation and to assess barriers to and facilitators of fistula creation in Canada. Design: Development and implementation of a survey. Setting: Community and academic VA programs. Participants: Nephrologists, surgeons, and nurses who are involved in VA programs across Canada. Measurements: Practice patterns regarding access creation and maintenance, including indications and contraindications to fistula creation, as well as program-wide facilitators of and barriers to VA. Methods: A small group of CSN VAWG members determined the scope and created several VA questions which were then reviewed by 5 additional VAWG members (4 nephrologists and 1 VA nurse) to ensure that questions were clear and relevant. The survey was then tested by the remaining members of the VAWG and refinements were made. The final survey version was submitted electronically to relevant clinicians (nephrologists, surgeons, and nurses) involved or interested in VA across Canada. Questions centered around 4 major themes: (1) Practice patterns regarding access creation (preoperative assessment and maturation assessment), (2) Practice patterns regarding access maintenance (surveillance and salvage), (3) Indications and contraindications for arteriovenous (AV) access creation, and (4) Facilitators of and barriers to fistula creation and utilization. Results: Eighty-two percent (84 of 102) of invited participants completed the survey; the majority were nurses or VA coordinators (55%) with the remainder consisting of nephrologists (21%) and surgeons (20%). Variation in practice was noted in utility of preoperative Doppler ultrasound, interventions to assist nonmaturing fistulas, and procedures to salvage failing or thrombosed AV-access. Little consensus was seen regarding potential contraindications to AV-access creation (with the exception of limited life expectancy and poor vasculature on preoperative imaging, which had high agreement). Frequent barriers to fistula utilization were primary failure (77% of respondents) and long maturation times (73%). Respondents from centers with low fistula prevalence also cited long surgical wait times as an important barrier to fistula creation, whereas those from centers with high fistula prevalence cited access to multidisciplinary teams and interventional radiology as keys to successful fistula creation and utilization. Conclusions: There is significant variation in VA practice across Canada and little consensus among Canadian clinicians regarding contraindications to fistula creation. Further high-quality studies are needed with regard to appropriate fistula placement to help guide clinical practice. PMID:29511569

Spontaneous cholecystocutaneous fistula (SCF) is a rare complication of neglected calculous biliary disease and also an extremely rare complication of gallbladder neoplasm. This pathology has become even rarer because of prompt diagnosis and expedient surgical intervention for gallstones. So far, there is one published report of a SCF due to gallbladder adenocarcinoma. We present the case of a woman aged 87 years, admitted to the Vth Department of Surgery, Clinical Municipal Hospital of Cluj-Napoca (Romania) for a tumoral mass located in the epigastrium. In the epigastrium, the patient had three skin orifices of about 1-2 mm each, through which purulent secretion occurred. The abdominal ultrasound highlighted a cholecystocutaneous fistula with the presence of a subcutaneous gallstone. Intraoperatively, we found a cholecystocutaneous fistula, a 1 cm subcutaneous gallstone, gallbladder with thickened walls containing a cylinder-shaped gallstone of 5÷3 cm. Fistulectomy, gallstones extraction and cholecystectomy were performed. The histopathological examination highlighted gallbladder adenocarcinoma. In conclusion, SCF can be the first significant manifestation of gallbladder cancer associated with neglected calculous biliary disease.

The purpose of this study was to evaluate the results and complications of standard ePTFE versus stretch ePTFE AV fistulas. Prospective randomised trial. University Hospital. During a 2-year period 37 patients received 17 stretch and 20 standard ePTFE graft AV fistulas. Patients were evaluated for the occurrence of complications and graft patency. Regular Duplex scans were performed to detect stenoses in the fistula circuit. Thrombotic events occurred in 40% of the standard ePTFE grafts, compared to 12% of the stretch ePTFE prostheses (p < 0.001). The incidence of puncture complications was similar in both groups. The cumulative primary patency rate in the stretch ePTFE group was significantly higher compared to the standard ePTFE group (1-year patency rates of 59% and 29%, respectively; p < 0.01). No differences in the duration of puncture site bleeding were observed. Duplex scanning showed a significantly greater number of stenoses in the standard ePTFE grafts. The new stretch ePTFE prosthesis has better primary patency rates and less stenoses due to intimal hyperplasia as compared to standard ePTFE grafts.

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.

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 international congresses. Trial registration number NCT02336867; pre-result. PMID:26674505

Urogenital fistula in the UK: a personal case series managed over 25 years.

Hilton, Paul

2012-07-01

Study Type - Therapy (case series) Level of Evidence 4 What's known on the subject? and What does the study add? Whilst several very large series of obstetric fistulae from the developing world have been published, data on fistulae as seen in the developed world are relatively few. Most fistulae in the UK are known to follow hysterectomy, and several risk factors are recognised. We have confirmed the common association with pelvic surgery, and in particular hysterectomy, but also show the broad range of other associated operations, including so called 'minimally invasive' procedures. High rates of both anatomical fistula closure and continence are shown, when a consistent approach to assessment, selection of surgical procedure, and postoperative care are applied. Successful closure is seen more often in women who have not undergone previous attempts at repair before referral, and as a result a pattern of surpra-regional management is proposed. Whilst overall the number of urogenital fistulae seen in the UK appears to be decreasing, there is a suggestion from these data that the rate of fistula formation following hysterectomy may be increasing; we are currently investigating this possibility through detailed interrogation of a national dataset. To review demography, aetiology, surgery and outcomes of women with urogenital fistula seen in one unit over the last 25 years; to provide data for comparison with a parallel study based on Hospital Episode Statistics. This is a prospective case series from a tertiary urogynaecology centre providing a de facto supra-regional fistula service. The women included had confirmed urogenital fistula referred between January 1986 and December 2010. Index cases were identified from a surgical database; data were entered prospectively and updated as appropriate; statistics are largely descriptive. The primary outcome is the patient's report of absence of urinary leakage. Secondary outcomes include operative or postoperative complications, anatomical closure of the fistula, other residual or new urinary symptoms, and the need for further intervention. In all, 348 women with urogenital fistula were referred; two-thirds were of surgical aetiology, with almost half following hysterectomy. Although 11% followed childbirth, most of these followed operative obstetric interventions. Spontaneous closure occurred in 6.9% of women and 291 underwent surgical treatment. The anatomical closure rate at first operation was 95.7%, although 2.2% reported residual urinary incontinence. The success rates were similar regardless of aetiology, although successful fistula closure was significantly more likely in women who had not had attempts at closure before referral (98.2 vs 88.2%; Fisher's exact test; P= 0.003). High rates of fistula closure are reported regardless of aetiology, although previous unsuccessful repair militates against successful outcome; this emphasises the appropriateness of centralisation of the management of this increasingly rare condition in UK practice. © 2011 THE AUTHOR.

Although malnutrition was found to increase the risk of intraabdominal and systemic complications in surgical patients, data for distal pancreatic resections are scarce. Data on 132 consecutive patients undergoing distal pancreatectomy as the primary procedure for pancreatic pathology, between 1996 and 2005, were reviewed to identify risk factors for postoperative complications and determine the impact of nutritional status. Nutritional assessment was performed with clinical and laboratory variables, including unintentional weight loss, body mass index, blood albumin level, lymphocyte count, and Nutritional Risk Index (NRI) and Instant Nutritional Assessment (INA) scores. Seventy-five (56.8%) patients developed 1 or more complications, including 18 (13.6%) cases of pancreatic fistula. The median values of NRI were significantly lower in patients with pancreatic fistula (96.9; 95% CI, 89.8 to 101.0) compared with those in the remaining subjects (102.5; 95% CI, 101.5 to 105.5; p=0.014). In the univariate analysis, the incidence of malnutrition defined by NRI (61% versus 30%, p=0.019) and the Instant Nutritional Assessment (67% versus 34%, p=0.017) was significantly higher in patients who developed pancreatic fistula. In the multivariate analysis, malnutrition characterized as NRI of 100 or less was the only factor that significantly increased the risk of pancreatic fistula, with an odds ratio of 8.12 (95% CI, 1.06 to 22.30). Malnutrition, as defined by composite nutritional assessment scales consisting of clinical and laboratory parameters, is a major risk factor for pancreatic fistula after distal pancreatectomy.

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 performedmore » 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.« less

Vascular access for home haemodialysis.

Home haemodialysis has been advocated due to improved quality of life. However, there are very little data on the optimum vascular access for it. A retrospective cohort study was carried on all patients who initiated home haemodialysis between 2011 and 2016 at a large university hospital. Access-related hospital admissions and interventions were used as primary outcome measures. Our cohort consisted of 74 patients. On initiation of home haemodialysis, 62 individuals were using an arteriovenous fistula as vascular access, while the remaining were on a tunnelled dialysis catheter. Of the 12 patients who started on a tunnelled dialysis catheter, 5 were subsequently converted to either an arteriovenous fistula ( n = 4) or an arteriovenous graft ( n = 1). During the period of home haemodialysis use, four arteriovenous fistula failed or thrombosed with patients continuing on home haemodialysis using an arteriovenous graft ( n = 3) or a tunnelled dialysis catheter ( n = 1). To maintain uninterrupted home haemodialysis, interventional rates were 0.32 per arteriovenous fistula/arteriovenous graft access-year and 0.4 per tunnelled dialysis catheter access-year. Hospital admission rates for patients on home haemodialysis were 0.33 per patient-year. Our study has shown that home haemodialysis can be safely and independently performed at home within a closely managed home haemodialysis programme. The authors also advocate the use of arteriovenous fistulas for this cohort of patients due to both low complication and intervention rates.

Open abdomen (OA) treatment in patients with peritonitis is increasing worldwide. Various temporary abdominal closure devices are being used. This study included patients with complicated diffuse secondary peritonitis, OA, and vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM). The aim of this study was to describe mortality and major morbidity in terms of delayed primary fascial closure and enteroatmospheric fistula rates. This was a single-academic-center retrospective study of consecutive patients with diffuse peritonitis, OA, and VAWCM between years 2008 and 2016. Descriptive and univariate analyses were performed. Forty-one patients were identified and analyzed. Median age was 59 years, preoperative septic shock was diagnosed in 54% (n = 22), and 59% (n = 24) had a postoperative peritonitis. Mortality was 29% (n = 12), and 76% (n = 31) of patients were admitted in the intensive care unit. The median duration of OA was 7 days with a median of two dressing changes. Delayed primary fascial closure rate among survivors was 92% (n = 33), and enteroatmospheric fistulas developed in 7% (n = 3). In a subgroup analysis, patients with OA in the primary laparotomy for peritonitis (n = 27) were compared with patients with OA in the subsequent laparotomies (n = 14). There were no significant differences between groups. The VAWCM technique in patients with complicated secondary diffuse peritonitis and OA yields excellent results in terms of delayed primary fascial closure rate and a low number of enteroatmospheric fistulas. It seems to be safe to close the abdomen at the index laparotomy, if possible, even if there is a risk of a need of OA later. Therapeutic/care management study, level IV.

Enterovesical fistula are pathological connections between the bladder and pelvic intestinal segments. It consists of a rare complication of neoplastic and inflammatory pelvic disorders, in addition to iatrogenic or traumatic injuries, and correlates with both high morbidity and mortality indexes. Male patient, 61 years old, admitted at the hospital clinics featuring abdominal pain and distension, vomiting and fecal retention. Patient's pathological precedents include high blood pressure, diabetes mellitus, vesical dysfunction and recurrent urinary tract infection on the past three years. Magnetic resonance imaging of abdomen and pelvis revealed enterovesical fistula in association with colon diverticular disease of the sigmoid. Management of choice consisted of partial colectomy with bowel lowering and partial cystectomy with surgical double-J stent insertion. Although consisting of a gastrointestinal primary affection, patients with enterovesical fistula usually search for medical help charging urinary tract features. In this particular case, our patient was admitted with gastrointestinal symptoms, reasoned by diagnostic delay, as the patient had already attended at multiple centers with urinary symptoms. Despite being an unusual affection, recurrent urinary tract infection associated with colon diverticular disease must always be considered at differential diagnosis of recurrent urinary tract infection as it concurs with high morbidity and mortality.

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. Copyright © 2016 Elsevier Ltd. All rights reserved.

Patients undergoing salvage laryngectomy are predisposed to radiation-induced hypothyroidism and impaired wound healing secondary to the tissue effects of prior treatment. The impact of hypothyroidism on postoperative wound healing is not established. A single-institution retrospective case series was performed. The inclusion criteria specified preoperatively euthyroid adults who underwent salvage laryngectomy with concurrent neck dissection between 1997 and 2015 for persistent or recurrent laryngeal squamous cell carcinoma after radiation or chemoradiation therapy (n = 182). The principal explanatory variable was postoperative hypothyroidism, defined as thyroid-stimulating hormone (TSH) higher than 5.5 mIU/L. The primary end points of the study were pharyngocutaneous fistulas and wounds requiring reoperation. Multivariate analysis was performed. The fistula rate was 47% among hypothyroid patients versus 23% among euthyroid patients. In the multivariate analysis, the patients who experienced hypothyroidism in the postoperative period had a 3.6-fold greater risk of fistula [95% confidence interval (CI) 1.8-7.1; p = 0.0002]. The hypothyroid patients had an 11.4-fold greater risk for a required reoperation (24.4 vs 5.4%) than the euthyroid patients (95% CI 2.6-49.9; p = 0.001). The risk for fistula (p = 0.003) and reoperation (p = 0.001) increased with increasing TSH. This corresponds to an approximate 12.5% incremental increase in the absolute risk for fistula and a 10% increase in the absolute risk for reoperation with each doubling of the TSH. Postoperative hypothyroidism independently predicts postoperative wound-healing complications. The association of hypothyroidism with fistula formation may yield opportunities to modulate wound healing with thyroid supplementation or to provide a biomarker of wound progression.

Thoracic duct fistula at the cervical level is a severe but rare complication following thyroid surgery, particularly associated to lateral dissection of the neck and to mediastinal goiter. we retrospectively analyzed chylous fistulas observed in a cohort of 13.224 patients underwent surgery for thyroid disease since 1986 to 2014, in the Unit of Endocrine Surgery, S. Maria University Hospital, Terni, Italy. We observed 20 cases of chylous fistula. Thirteen patients underwent primary surgery in our institution while the remaining 7 cases had been referred to our Department from other hospitals for an already diagnosed lymphatic leak. Surgical procedures carried out included total thyroidectomy for mediastinal goiter in 4 patients, total thyroidectomy for cancer in 2 patients, unilateral functional lymphadenectomy in 11 patients and bilateral in 3. Intraoperative repair was carried out in 4 cases. Of the remaining 16 cases, 4 of the 6 fistulas with low flow leakage healed in about 30 days of conservative treatment, 2 cases instead required surgical repair. All 10 patients with "high-flow" fistula underwent surgery. Despite surgery was performed later, postoperative course in patients with late surgical repair is similar to what observed in those patients with early surgical repair. Both groups underwent cervical drainage removal in post-operative day 4. Healing of a cervical chylous fistula can be achieved by conservative medical therapy (nutritional and pharmacological) but in case of therapeutic failure with rapid decrease of general condition, the surgical approach is necessary. In our experience, duct ligation after unsuccessful conservative treatment, is the only resolutive treatment. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

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. 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. 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-threatening 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%). 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.

J. Marion Sims and the Vesicovaginal Fistula: Historical Understanding, Medical Ethics, and Modern Political Sensibilities.

PubMed

Wall, L Lewis

To review the historical background surrounding the early work of Dr. J. Marion Sims, who developed the first consistently successful surgical technique for the repair of obstetric vesicovaginal fistulas by operating on a group of young, enslaved, African American women who had this condition between 1846 and 1849. Review of primary source documents on Sims and his operations, early 19th century clinical literature on the treatment of vesicovaginal fistula, the introduction of ether and chloroform anesthesia into surgical practice, and the literature on the early 19th century medical ethics pertaining to surgical innovation. The goals are to understand Sims's operations within the clinical context of the 1840s and to avoid the problems of "presentism," in which beliefs, attitudes, and practices of the 21st century are anachronistically projected backward into the early 19th century. The object is to judge Sims within the context of his time, not to hold him accountable to standards of practice which were not developed until a century after his death. A narrative of what Sims did is presented within the context of the therapeutic options available to those with fistula in the early 19th century. Review of the available material demonstrates that Sims' first fistula operations were legal, that they were carried out with express therapeutic intent for the purpose of repairing these women's injuries, that they conformed to the ethical requirements of his time, and that they were performed with the patients' knowledge, cooperation, assent, and assistance.

The primary failure rate for arteriovenous fistula (AVF) creation under local anesthesia for hemodialysis is about 30%. Axillary brachial plexus block (BPB) may improve blood flow through blood vessels used in fistula creation; it may improve the AVF blood flow and thus may reduce the primary failure rate after 3 months. Hundred and forty patients with chronic renal failure scheduled for AVF creation for hemodialysis were divided into two equal groups; Group 1 (AxBP-G) received ultrasound (US) guided axillary BPB, and Group 2 (LI-G) received local infiltration. We recorded the measurements of the brachial and radial arteries before and after anesthesia and the AVF blood flow in both groups at three different time points. Furthermore, the primary failure rate was recorded in each group and compared. After anesthesia, the mean radial artery blood flow in the AxBP-group was 3.52 ml/min more than the LI-group, and the brachial artery diameter was also 0.68 mm more than in the LI-group, both differences were statistically significant ( P < 0.05). There were significant increases ( P < 0.05) in the AVF blood flow in the AxBP-group more than the LI-group with mean differences of 29.6, 69.8, and 27.2 ml/min at 4 h, 1 week, and 3 months, respectively. The overall mean of AVF blood flow was 42.21 ml/min more in the AxBP group than the LI-group a difference which is statistically significant ( P < 0.001). The primary failure rate was 17% in the AxBP group versus 30% in the LI-group; however, this difference is not significant statistically ( P = 0.110). The US-guided axillary block increases AVF blood flow significantly more than local infiltration and nonsignificantly decreases the primary failure rate of the AVF after 3 months.

Gastrointestinal fistula is the most serious complication of esophageal and gastric cardiac cancer surgery. According to occurrence of organ, gastrointestinal fistula can be divided into anastomotic fistula, gastric fistula; According to occurrence site, fistula can be divided into cervical fistula, thoracic fistula; According to time of occurrence, can be divided into early, middle and late fistula. There are special types of fistula including ‘thoracic cavity’-stomach-bronchial fistula, ‘thoracic cavity’-stomach-aortic fistula. Early diagnosis needs familiarity with various types of clinical gastrointestinal fistulas. However, Prevention of gastrointestinal fistula is better than cure, including perioperative nutritional support, respiratory tract management, and acid suppression, positive treatment of complications, antibiotic prophylaxis, and gastrointestinal decompression and eating timing. Prevention can effectively reduce the incidence of postoperative gastrointestinal fistula. Collectively, early diagnosis and treatment, nutritional supports are key to reducing mortality of gastrointestinal fistula.

Spinal dural arteriovenous fistulas: the most frequent vascular malformations of the spinal cord.

PubMed

Iglesias Gordo, J; Martínez García, R

Spinal dural arteriovenous fistulas are produced by direct communication between the arterial and venous systems of the spinal cord, causing hypertension in the latter with spinal cord dysfunction. It is a rare pathology with unknown etiology and non-specific clinical symptoms that usually results in a delayed diagnosis. Often radiologists are the first to guide the disease towards an adequate diagnosis. Characteristic findings can be seen through MR or MR angiography, and may even locate the fistula in a high percentage of cases, although the pathology must be confirmed by spinal angiography. There are two treatment modalities: endovascular and surgical therapy. Endovascular treatment has improved in recent years with the advantages of a less invasive approach and is therefore usually chosen as primary therapy. In this article we review the main clinical manifestations, imaging findings and treatment of this pathology. Copyright © 2017 SERAM. Publicado por Elsevier España, S.L.U. All rights reserved.

PLF is considered rare, but is known to occur during childbirth, straining, weightlifting, head trauma, and diving with middle ear equalizing problems. It has also, anecdotally, been described in connection with flying. The symptoms are uncharacteristic vertigo and, in some cases, hearing impairment and tinnitus. This study describes four cases of PLF during a period of 6 mo in a major Scandinavian airline company employing approximately 3000 cabin attendants (CAs). None of the cases were diagnosed at the primary health care level. All were referred to the Aviation Medical Center for investigation. The PLF diagnosis was based on the case history, Platform Pressure Test (a fistula test), and other vestibular tests. Only one CA has been able to return to flying duties. The article emphasizes the risk of flying with poor middle ear equalization and the necessity of reminding crews and airline companies to "never fly with a common cold".

The purpose of this paper is to communicate our experience in the salvage of thrombosed haemodialysis vascular accesses using interventional radiology techniques. In the last four years, we have treated, by radiological means, 101 thrombosed haemodialysis vascular accesses. There were 44 autologous arteriovenous fistulas (43.56%) and 57 PTFE grafts (56.44%). There were 69 men (68.3%) and 32 women (31.7%). The mean age was 67.73 years (range 33-84). The mean vascular access age was 23.79 months (range 1-132). Manual catheter-directed aspiration was used. Fragmented, triturated or pushed the thrombus against the pulmonary circulation was avoided in all cases. 78 accesses were salvaged (77.2%). Autologous fistulas average and PTFE grafts success rate were 84.44% and 71.42% respectively. Angioplasty in one or more lesions after thromboaspiration was performed in all accesses, except six (5.9%). Metallic endoprostheses were implanted in 14 accesses (13.9%). Mean follow-up was 9 months (range 0-44). Primary patency was 42.3% +/- 5 at 6 months and 32% +/- 4 at one year. Autologous fistulas patency was better than PTFE grafts patency (p < or =0,05). Our results suggest thrombosed autologous arteriovenous fistulas salvage is better than PTFE grafts. This justifies interventional radiology techniques in these situations.

Arteriovenous access failure frequently occurs in people on hemodialysis and is associated with morbidity, mortality and large healthcare expenditures. Omega-3 polyunsaturated fatty acids (omega-3 PUFA) may improve access outcomes via pleiotropic effects on access maturation and function, but may cause bleeding complications. Systematic review with meta-analysis. Adults requiring hemodialysis via arteriovenous fistula or graft. Trials evaluating omega-3 PUFA for arteriovenous access outcomes identified by searches in CENTRAL, MEDLINE, and Embase to 24 January 2017. Omega-3 PUFA. Primary patency loss, dialysis suitability failure, access abandonment, interventions to maintain patency or assist maturation, bleeding, gastrointestinal side-effects, all-cause and cardiovascular mortality, hospitalization, and treatment adherence. Treatment effects were summarized as relative risks (RR) and 95% confidence intervals (CI). Evidence was assessed using GRADE. Five eligible trials (833 participants) with a median follow-up of 12 months compared peri-operative omega-3 PUFA supplementation with placebo. One trial (n=567) evaluated treatment for fistulae and four (n=266) for grafts. Omega-3 PUFA supplementation prevented primary patency loss with moderate certainty (761 participants, RR 0.81, CI 0.68-0.98). Low quality evidence suggested, that omega-3 PUFA may have had little or no effect on dialysis suitability failure (536 participants, RR 0.95, CI 0.73-1.23), access abandonment (732 participants, RR 0.78, CI 0.59-1.03), need for interventions (732 participants, RR 0.82, CI 0.64-1.04), or all-cause mortality (799 participants, RR 0.99, CI 0.51-1.92). Bleeding risk (793 participants, RR 1.40, CI 0.78-2.49) or gastrointestinal side-effects (816 participants, RR 1.22, CI 0.64-2.34) from treatment were uncertain. There was no evidence of different treatment effects for grafts and fistulae. Small number and methodological limitations of included trials. Omega-3 PUFA supplementation probably protects against primary loss of arteriovenous access patency, but may have little or no effect on dialysis suitability failure, access interventions or access abandonment. Potential treatment harms are uncertain. Copyright © 2018 National Kidney Foundation, Inc. All rights reserved.

The Glans-Urethral Meatus-Shaft (GMS) score is a concise and reproducible way to describe hypospadias severity. We classified boys undergoing primary hypospadias repair to determine the correlation between GMS score and postoperative complications. Between February 2011 and August 2013, patients undergoing primary hypospadias repair were prospectively scored using the GMS classification. GMS scoring included a 1-4 scale for each component: G - glans size/urethral plate quality, M - meatal location, and S - degree of shaft curvature, with more unfavorable characteristics assigned higher scores [Figure]. Demographics, repair type, and complications (urethrocutaneous fistula, meatal stenosis, glans dehiscence, phimosis, recurrent chordee and stricture) were assessed. Total and individual component scores were tested in uni- and multivariate analysis. Two-hundred and sixty-two boys (mean age 12.3 ± 13.7 months) undergoing primary hypospadias repair had a GMS score assigned. Mean GMS score was 7 ± 2.5 (G 2.1 ± 0.9, M 2.4 ± 1, S 2.4 ± 1). Mean clinical follow-up was 17.7 ± 9.3 months. Thirty-seven children (14.1%) had 45 complications. A significant relationship between the total GMS score and presence of any complication (p < 0.001) was observed; for every unit increase in GMS score the odds of any postoperative complication increased 1.44 times (95% CI, 1.24-1.68). Urethrocutaneuous fistula was the most common complication, occurring in 21 of 239 (8.8%) of single-stage repairs. Patients with mild hypospadias (GMS 3-6) had a 2.4% fistula rate vs. 11.1% for moderate (GMS 7-9) and 22.6% for severe (GMS 10-12) hypospadias (p < 0.001). Degree of chordee was an independent predictor of fistula on multivariate analysis; S4 (>60° ventral curvature) patients were 27 times more likely to develop a fistula than S1 (no curvature) boys (95% CI, 3.2-229). The GMS score is based on anatomic features (i.e. glans size/urethral plate quality, location of meatus, and degree of chordee) felt to most likely impact functional and cosmetic outcomes following hypospadias repair. We demonstrated a statistically significant increase in the likelihood of any postoperative complication with every unit increase in total GMS score. The concept that factors aside from meatal location affect hypospadias repair and outcomes is not novel, and degree of ventral curvature and urethral plate quality are often cited as important factors. In our series, boys with greater than 60° of ventral curvature undergoing a single-stage repair were 27 times more likely to develop a fistula than those without chordee on multivariate analysis, making severe curvature an independent predictor of urethrocutaneous fistula formation. That meatal location did not retain significance on multivariate analysis highlights the importance of considering the entire hypospadias complex when determining severity, rather than just evaluating the position of the meatus. Our study has several limitations that warrant consideration. While GMS scores were assigned prospectively, the data was collected retrospectively, subjecting it to flaws inherent with such study design. Furthermore, type of repair is influenced by surgeon preference and subjective assessment of hypospadias characteristics not incorporated in our scoring system (i.e. tissue quality, urethral hypoplasia, penoscrotal transposition). Despite these limitations, our study demonstrates a strong correlation between the GMS classification and surgical complications, furthering supporting its potential as a tool to standardize hypospadias severity and gauge postoperative complications. The Glans-Urethral Meatus-Shaft (GMS) classification provides a means by which hypospadias severity and reporting can be standardized, which may improve inter-study comparison of reconstructive outcomes. There is a strong correlation between complication risk and total GMS score. Degree of chordee (S score) is independently predictive of fistula rate.

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.

The objective of this study is to test the null hypothesis that an S-shaped surgical incision versus conventional (straight) skin incision in the creation of autogenous radiocephalic arteriovenous fistulas (RCAVFs) have no impact on the primary end-point of primary functional maturation and secondary end points of stenosis and thrombosis. A prospective observational comparative consecutive study with intention-to-treat on individuals undergoing only radiocephalic arteriovenous fistula (RCAVFs) over a period of 12 months was conducted. Variables on patient's demographics, comorbidities, anesthesia type, mean arterial blood pressure, thrill, laterality, cephalic vein and radial artery diameter were collated. The test of probability was assessed through Chi-Square, Kaplan-Meier survival estimator and Log-Rank analysis. Total of n = 83 individuals with median age of 67 years (IQR, 20-89) and male predominance 83% during this period were subjected to RCAVF formation. Total of n = 45 patients in straight skin incision were compared to n = 38 individuals in S-shaped group. Despite equal prevalence of demographics, comorbidities, anesthesia type, mean arterial blood pressure (MAP), thrill, laterality, cephalic vein and radial artery diameter ( p  > 0.05) higher incidence of juxta-anastomotic stenosis was noted in the straight skin incision group ( p  = 0.029) in comparative and survival analysis (Log-Rank, p  = 0.036). The maturation of the entire cohort was 69% (S-shaped 76% vs. straight group 62%) (p > 0.05). The outcome of this study demonstrates that S-shaped surgical skin incision is associated with a lower incidence of stenosis in comparison to straight incision type in RCAVF formation.

To compare the efficacy and safety of cutting balloon angioplasty (CBA) versus high-pressure balloon angioplasty (HPBA) for the treatment of hemodialysis autogenous fistula stenoses resistant to conventional percutaneous transluminal angioplasty (PTA). In a prospective, randomized clinical trial involving patients with dysfunctional, stenotic hemodialysis arteriovenous fistulas (AVFs), patients were randomized to receive CBA or HPBA if conventional PTA had suboptimal results (ie, residual stenosis > 30%). A total of 516 patients consented to participate in the study from October 2008 to September 2011, 85% of whom (n = 439) had technically successful conventional PTA. The remaining 71 patients (mean age, 60 y; 49 men) with suboptimal PTA results were eventually randomized: 36 to the CBA arm and 35 to the HPBA arm. Primary and secondary target lesion patencies were determined by Kaplan-Meier analysis. Clinical success rates were 100% in both arms. Primary target lesion patency rates at 6 months were 66.4% and 39.9% for CBA and HPBA, respectively (P = .01). Secondary target lesion patency rates at 6 months were 96.5% for CBA and 80.0% for HPBA (P = .03). There was a single major complication of venous perforation following CBA. The 30-day mortality rate was 1.4%, with one non-procedure-related death in the HPBA group. Primary and secondary target lesion patency rates of CBA were statistically superior to those of HPBA following suboptimal conventional PTA. For AVF stenoses resistant to conventional PTA, CBA may be a better second-line treatment given its superior patency rates. © 2014 SIR Published by SIR All rights reserved.

It is estimated that as many as 3.5 million women worldwide suffer from obstetric urinary fistula. This public health tragedy is a result of obstructed labor and inadequate access to health care, and its eradication lies in prevention and treatment. Efforts at prevention should be made through targeted education and public intervention for improved nutrition, access to health care, and women's social status. Diagnosis and treatment in limited resource settings can occur, and there are specific recommendations regarding nonsurgical and surgical approaches to care. Treatment success may be complicated by social, psychological, and clinical factors, with reintegration a primary concern for this group of women.

The aim of this study is to evaluate the etiology of perianal abscess or discharges in neonates and infants and some of them are perianal sinuses with blind inner end without connection to the anal canal, and some of these cases have a different histological pattern. Complete surgical excision and primary closure of their wounds can cure these patients. Between January 1988 and December 2000, (81) neonates and infants (aged 2 weeks to 2 years) with perianal sinuses, fistula-in-ano abscess dealt in the Al-Zahrawi and Al-Khansa Teaching Hospitals, Mosul, Iraq, were studied. Fifty-one patients displayed an onset of symptoms during their first year of age, all cases had a gentle probing and proctoscopy under general anesthesia, and the discharge from abscess from the patients were sent for culture. Thirty patients with proper sinuses had excision of the sinus and primary closure; children with fistulae underwent fistulectomy; perianal abscesses drained. All the excised specimens were examined histopathologically. All children, except 3, were boys. Out of the 81 cases studied, 30 patients (37%) proved to have proper sinuses with blind inner end. Eight of these showed a different histological pattern, and in 2 cases, the histopathology was that of rectal duplication, the microbiology of the discharge from the proper sinuses was showing a predominance of non-gut derived organisms. All patients cured by excision of the sinuses and primary closure. Fistulae are the most common perianal discharging lesions in neonates and infants, blind sinuses are another cause in a considerable number. We propose a diagnostic strategy and treatment for those children presenting with discharging perianal lesions; for anticipation of these sinuses 3 points need to be considered before attempting surgery. 1) Blind sinus tract on gentle probing. 2) Normal anal and rectal mucosa on proctoscopy. 3) High bacterial yield of non-gut derived organisms on culture of the pus or discharge. Their treatment is by simple excision (coring) and primary closure; this method will shorten the healing and recovery time.

We present the largest recorded case series of holmium:YAG laser use in otolaryngology. This laser's hand-held delivery device is easier to manipulate compared with other ENT lasers, and its pulsed delivery mode gives it enhanced cutting and coagulation properties. We conducted a 12-year, retrospective study of holmium:YAG laser use in a tertiary referral centre. Sixty-eight patients were included. Nineteen received primary laser treatment of squamous cell carcinoma of the upper aerodigestive tract (nine with simultaneous neck dissection), and 49 underwent either palatine or lingual tonsillectomy for benign disease. One cancer patient developed a pharyngo-cutaneous fistula, and a second suffered a secondary haemorrhage. No other complications were recorded. There were no local recurrences. The holmium:YAG laser is safe and effective for benign and malignant otolaryngological conditions. In cancer treatment, it may be best to delay neck dissection until the primary site has healed, in order to avoid fistula formation.

Predictors of Salivary Fistulas in Patients Undergoing Salvage Total Laryngectomy

Wang, Steven J.

2014-01-01

Background. Salivary fistula is a common complication after salvage total laryngectomy. Previous studies have not considered the number of layers of pharyngeal closure and have not classified fistulas according to severity. Our objective was to analyze our institutional experience with salvage total laryngectomy, categorize salivary fistulas based on severity, and study the effect of various pharyngeal closure techniques on fistula incidence. Methods. Retrospective analysis of 48 patients who underwent salvage total laryngectomy, comparing pharyngeal closure technique and use of a pectoralis major flap with regard to salivary fistula rate. Fistulas were categorized into major and minor fistulas based on whether operative intervention was required. Results. The major fistula rate was 18.8% (9/48) and the minor fistula rate was 29.2% (14/48). The overall (major plus minor) fistula rate was 47.9%. The overall fistula and major fistula rates decreased with increasing the number of closure layers and with use of a pectoralis major flap; however, these correlations did not reach statistical significance. Other than age, there were no clinicopathologic variables associated with salivary fistulas. Conclusion. For salvage total laryngectomies, increasing the number of closure layers or use of a pectoralis major flap may reduce the risk of salivary fistula. PMID:27355065

The extension of the surgery and closure type of the pharynx can be the determinants in the pharyngocutaneous fistula development. The objective of the study is to evaluate the incidence of pharingocutaneous salivary fistulae after total laryngectomies comparing manual and mechanical sutures. The study is designed as non-randomized, prospective clinical study. Sixty patients with squamous cell carcinoma were submitted to total laryngectomies. In 30 cases, the linear stapler (75 mm) closure (surgical technique described in details) and in other 30 cases manual suture was used. The cases of mechanical suture were prospective and consecutive and the cases of manual suture were a review series of patients who underwent a manual suture of pharynx, in the same period of time. The statistical analysis between the two groups concluded that both were comparable. Fistulae incidence was 6.7% (2/30) in the group with the mechanical suture and 36.7% (11/30) in the group with manual suture closure, presenting a significant difference (p = 0.0047). The total laryngectomy with mechanical closure is an easy and fast learning technique, allowing watertight closure of the pharynx with a low risk of contamination of the surgical field. It is an assured method, even in previously irradiated patients, since we respect the limits of its indication regarding the extension of primary tumor that must be confirmed by previous suspension laryngectomy performed in the operating room.

The ARM-Net (anorectal malformation network) consortium held a consensus meeting in which the classification of ARM and preoperative workup were evaluated with the aim of improving monitoring of treatment and outcome. The Krickenbeck classification of ARM and preoperative workup suggested by Levitt and Peña, used as a template, were discussed, and a collaborative consensus was achieved. The Krickenbeck classification is appropriate in describing ARM for clinical use. The preoperative workup was slightly modified. In males with a visible fistula, no cross-table lateral X-ray is needed and an anoplasty or (mini-) posterior sagittal anorectoplasty can directly be performed. In females with a small vestibular fistula (Hegar size <5 mm), a primary repair or colostomy is recommended; the repair may be delayed if the fistula admits a Hegar size >5 mm, and in the meantime, gentle painless dilatations can be performed. In both male and female perineal fistula and either a low birth weight (<2,000 g) or severe associated congenital anomalies, prolonged preoperative painless dilatations might be indicated to decrease perioperative morbidity caused by general anesthesia. The Krickenbeck classification is appropriate in describing ARM for clinical use. Some minor modifications to the preoperative workup by Levitt and Peña have been introduced in order to refine terminology and establish a comprehensive preoperative workup.

From 1969 to 1985, 129 patients with combined pancreatoduodenal injuries were treated at one urban trauma center. A total of 104 patients (80.6%) had penetrating wounds, and multiple visceral and vascular injuries were usually associated with the pancreatoduodenal injury. Primary repair or resection of one or both organs coupled with pyloric exclusion and gastrojejunostomy (68 patients) and drainage was used in 79 patients (61.2%) in the entire study and in 59% (36 of 61) of all patients treated since 1976. Simple primary repair of one or both organs and drainage was performed in 31 patients (24%), whereas the remaining 19 patients (14.8%) had pancreatoduodenectomies (13 patients) or no repair before exsanguination (six patients). Major pancreatoduodenal complications occurring in the 108 patients surviving more than 48 hours included pancreatic fistulas (25.9%), intra-abdominal abscess formation (16.6%), and duodenal fistulas (6.5%). The overall mortality rate for the study was 29.5% (38 of 129). The acute mortality rate with these injuries will remain high secondary to injuries to associated organs and vascular structures. The morbidity and late mortality rates related to the moderate to severe pancreatoduodenal injury itself can be decreased by the addition of pyloric exclusion and gastrojejunostomy to the primary repairs.

Background Obstetric fistula although virtually eliminated in high income countries, still remains a prevalent and debilitating condition in many parts of the developing world. It occurs in areas where access to care at childbirth is limited, or of poor quality and where few hospitals offer the necessary corrective surgery. Methods This was a prospective observational study where all women who attended Mbarara Regional Referral Hospital in western Uganda with obstetric fistula during the study period were assessed pre-operatively for social demographics, fistula characteristics, classification and outcomes after surgery. Assessment for fistula closure and stress incontinence after surgery was done using a dye test before discharge Results Of the 77 women who were recruited in this study, 60 (77.9%) had successful closure of their fistulae. Unsuccessful fistula closure was significantly associated with large fistula size (Odds Ratio 6 95% Confidential interval 1.46-24.63), circumferential fistulae (Odds ratio 9.33 95% Confidential interval 2.23-39.12) and moderate to severe vaginal scarring (Odds ratio 12.24 95% Confidential interval 1.52-98.30). Vaginal scarring was the only factor independently associated with unsuccessful fistula repair (Odds ratio 10 95% confidential interval 1.12-100.57). Residual stress incontinence after successful fistula closure was associated with type IIb fistulae (Odds ratio 5.56 95% Confidential interval 1.34-23.02), circumferential fistulae (Odds ratio 10.5 95% Confidential interval 1.39-79.13) and previous unsuccessful fistula repair (Odds ratio 4.8 95% Confidential interval 1.27-18.11). Independent predictors for residual stress incontinence after successful fistula closure were urethral involvement (Odds Ratio 4.024 95% Confidential interval 2.77-5.83) and previous unsuccessful fistula repair (Odds ratio 38.69 95% Confidential interval 2.13-703.88). Conclusions This study demonstrated that large fistula size, circumferential fistulae and marked vaginal scarring are predictors for unsuccessful fistula repair while predictors for residual stress incontinence after successful fistula closure were urethral involvement, circumferential fistulae and previous unsuccessful fistula repair.

The impact of pregnancy on the course of Crohn disease is largely unknown. Retrospective surveys have suggested a variable effect, but there are limited population-based clinical data. We hypothesized pregnant women with Crohn disease will have similar rates of surgical disease as a nonpregnant Crohn disease cohort. International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify female Crohn patients from all patients admitted using the Nationwide Inpatient Sample (1998-2009). Women were stratified as either pregnant or nonpregnant. We defined Crohn-related surgical disease as peritonitis, gastrointestinal hemorrhage, intra-abdominal abscess, toxic colitis, anorectal suppuration, intestinal-intestinal fistulas, intestinal-genitourinary fistulas, obstruction and/or stricture, or perforation (excluding appendicitis). Of the 92,335 women admitted with a primary Crohn-related diagnosis, 265 (0.3%) were pregnant. Pregnant patients were younger (29 versus 44 y; P<0.001) and had lower rates of tobacco use (6% versus 13%; P<0.001). Pregnant women with Crohn disease had higher rates of intestinal-genitourinary fistulas (23.4% versus 3.0%; P<0.001), anorectal suppuration (21.1% versus 4.1%; P<0.001), and overall surgical disease (59.6% versus 39.2%; P<0.001). On multivariate logistic regression analysis controlling for malnutrition, smoking, age, and prednisone use, pregnancy was independently associated with higher rates of anorectal suppuration (odds ratio [OR], 5.2; 95% confidence interval [CI], 3.8-7.0; P<0.001), intestinal-genitourinary fistulas (OR, 10.4; 95% CI, 7.8-13.8; P<0.001), and overall surgical disease (OR, 2.9; 95% CI, 2.3-3.7; P<0.001). Pregnancy in women with Crohn disease is a significant risk factor for Crohn-related surgical disease, in particular, anorectal suppuration and intestinal-genitourinary fistulas.

Creation of an arteriovenous fistula (AVF) in patients with advanced atherosclerotic changes of the artery is often a challenge for the physician due to difficulties in suturing the vein to the side of the frangible artery. The sleeve technique relies on advancing the end of the artery into the lumen of the vein and protecting the anastomosis by adventitial sutures. The sleeve technique was performed in 23 patients with chronic kidney disease stage IV and V and included hemodialysis patients. Their mean age was 60.8 ± 14.8 years and hemodialysis treatment time 49.8 ± 40.2 months. The most frequent causes of chronic kidney disease are ischemic nephropathy (43%, n = 10) and type l diabetes (21%, n = 5). Only patients with extremely advanced atherosclerotic were recruited and analyzed. The primary patency rate was 67%, 59%, 44% and 28% at 6, 12, 24, and 36 months, respectively. The secondary patency rate was 67%, 61%, 50% and 37% at 6, 12, 24, and 36 months, respectively. In three patients the AVF failed directly after the operation. Delayed fistula failure occurred in seven patients. The overall success in the creation of a functioning fistula was achieved in 15 of the 23 patients (65%). No serious complications were observed. In patients with calcified atherosclerotic plaques, which constitute a barrier or make it difficult to suture the vein to the side of the artery, the sleeve method may be considered as an alternative before abandoning the creation of a fistula on the forearm. The technique is much simpler than the standard end-to-side or side-to-side anastomosis.

Basilic vein transposition fistulas (BVTFs) and prosthetic bridge grafts (PBGs) provide good vascular access for hemodialysis. To evaluate the patency and complication rates after arteriovenous fistula formation, a concurrent series of patients was reviewed. Between September 2003 and September 2009, 147 hemodialysis access procedures were performed in 147 consecutive patients at Van Research and Training Hospital and Yuzuncu Yil University Hospital, Van, Turkey. All access procedures were planned on the basis of preoperative duplex scans of arm and forearm veins. Functional patency was defined as the ability to cannulate hemodialysis patients successfully. Primary and secondary cumulative functional patency rates of BVTFs and PBGs were determined with life-table analysis and differences were analyzed with retrospective study. Differences in revision rates, including thrombolysis thrombectomies and operative revisions, were analyzed with the Fisher exact t-test. Mean follow-up was 15 months (range, 3-24 months). Risk factors were similar between the two groups. BVTFs had better patency at 15 months. The dialysis access complications were higher in the PBG group versus BVTF group, and the PBG group had a higher infection rate than the BVTF group. The primary and secondary patency rates were superior in the BVTF group. Our data strongly support the contention that as long as the patient is a candidate for an upper arm BVTF based on anatomical criteria, BVTF always be considered before a PBG. Copyright © 2011.

Introduction Gastrocutaneous fistulas remain an uncommon complication of upper gastrointestinal surgery. Less common but equally problematic are gastrocutaneous fistulas secondary to non-healing gastrostomies. Both are associated with considerable morbidity and mortality. Surgical repair remains the gold standard of care. For those unfit for surgical intervention, results from conservative management can be disappointing. We describe a case series of seven patients with gastrocutaneous fistulas who were unfit for surgical intervention. These patients were managed successfully in a minimally invasive manner using the Surgisis® (Cook Surgical, Bloomington, IN, US) anal fistula plug. Methods Between September 2008 and January 2009, seven patients with gastrocutaneous fistulas presented to Wishaw General Hospital. Four gastrocutaneous fistulas represented non-healing gastrostomies, two followed an anastomotic leak after an oesophagectomy and one following an anastomotic leak after a distal gastrectomy. All patients had poor nutritional reserve with no other identifiable reason for failure to heal. All were deemed unfit for surgical intervention. Five gastrocutaneous fistulas were closed successfully using the Surgisis® anal fistula plug positioned directly into the fistula tract under local anaesthesia and two gastrocutaneous fistulas were closed successfully using the Surgisis® anal fistula positioned endoscopically using a rendezvous technique. Results For the five patients with gastrocutaneous fistulas closed directly under local anaesthesia, oral alimentation was reinstated immediately. Fistula output ceased on day 12 with complete epithelialisation occurring at a median of day 26. For the two gastrocutaneous fistulas closed endoscopically using the rendezvous technique, oral alimentation was reinstated on day 5 with immediate cessation of fistula output. Follow-up upper gastrointestinal endoscopy confirmed re-epithelialisation at eight weeks. In none of the cases has there been fistula recurrence (range of follow-up duration: 30–59 months). Conclusions Surgisis® anal fistula plugs can be used safely and effectively to close gastrocutaneous fistulas in a minimally invasive manner in patients unfit for surgical intervention.

To determine the magnitude of traumatic gynecologic fistulas caused by sexual violence in the Democratic Republic of Congo. A retrospective analysis of hospital records from 604 consecutive patients who received treatment for gynecologic fistulas at Panzi Hospital between November 2005 and November 2007. Of the 604 patients, 24 (4%) reported that their fistulas had been caused by sexual violence; of these, 5 (0.8%) had developed fistulas as a direct result of forced penetration with foreign objects and/or gang rapes. Of the remaining patients, 6 had a fistula before they were raped, 9 developed iatrogenic fistulas following inappropriate instrumentation to manage rape-induced spontaneous abortion or stillbirth, or after abdominal hysterectomy, and 4 developed fistulas after prolonged and obstructed labor. Traumatic fistulas are rare compared to obstetric fistulas. Fistulas indirectly related to sexual violence are likely to be more common than those directly related. All fistulas resulting from sexual violence, whether direct or indirect, should be considered traumatic and special care should be given to these women.

Assessment and classification of fistula-in-ano in patients with Crohn's disease by hydrogen peroxide enhanced transanal ultrasound.

Crohn's disease is well known for its perianal complications, among which fistulas-in-ano are the most common abnormalities. Fistulas-in-ano in Crohn's disease tend to be complex and have a high recurrence rate. Therefore the role of surgery is generally more conservative. Hydrogen peroxide enhanced transanal ultrasound has proven superior to physical examination, fistulography, computed tomography, and conventional ultrasound in demonstrating the fistula tract. This study examined the fistula tracks in patients with Crohn's disease. Forty-one patients with Crohn's disease and fistula-in-ano were investigated using physical examination, sondage of the fistula, proctoscopy and transanal ultrasound. Hydrogen peroxide was infused via a small catheter into the fistula. The main track and the ramification of the fistula were classified according to the anatomical Parks' classification. Only 9 (22%) patients had a single inter- or transsphincteric fistula. In 5 (12%) patients a single supra- or extrasphincteric fistula (high fistula) was found, in 14 (34%) more than one fistula track (ramified), and in 13 (32%) an anovaginal fistula. Thus 78% of patients had a surgically difficult to treat fistula. In the ramified fistula the main track follows the Parks' classification, but ramifications can have a bizarre pattern which is not in agreement with this classification. Optimal documentation by means of hydrogen peroxide enhanced transanal ultrasound is therefore mandatory before surgery or before other therapies such as anti-tumor necrosis factor treatment.

Fistulous tracts are a hallmark of Crohn's Disease. However, solid organ to intestinal fistulas are rare with previously few case reports of colosplenic fistulas and one case report of an enterohepatic fistula. We review the available literature and present the first case report of an enterohepatic fistula in a female with Crohn's Disease to be treated operatively. The patient did well postoperatively with complete resolution of her fistula. Crohn's Disease is an inflammatory bowel disease that can present with fistulas. However, a fistula between the liver and bowel is exceedingly rare with only one previous case report. This is the first report of an enteroheptic fistula that has been managed successfully with an operation. Not all enteroenteric fistulas are apparent preoperatively. When discovered, laparoscopic enterohepatic fistula takedown is feasible for this rare disease process manifestation. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

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

Fistulas represent failure of cleft palate repair. Secondary and tertiary fistula repair is challenging, with high recurrence rates. In the present retrospective study, we review the efficacy of using acellular dermal matrix as an interposition layer for cleft palate fistula closure in 20 consecutive patients between 2013 and 2016. Complete fistula closure was obtained in 16 patients; 1 patient had asymptomatic recurrent fistula; 2 patients had partial closure with reduction of fistula size and minimal nasal regurgitation; 1 patient developed a recurrent fistula without changes in symptoms (success rate of 85%). We conclude that utilizing acellular dermal matrix for cleft palate fistula repair is safe and simple with a high success rate.

In 2005, the International Study Group of Pancreatic Fistula developed a definition and grading of postoperative pancreatic fistula that has been accepted universally. Eleven years later, because postoperative pancreatic fistula remains one of the most relevant and harmful complications of pancreatic operation, the International Study Group of Pancreatic Fistula classification has become the gold standard in defining postoperative pancreatic fistula in clinical practice. The aim of the present report is to verify the value of the International Study Group of Pancreatic Fistula definition and grading of postoperative pancreatic fistula and to update the International Study Group of Pancreatic Fistula classification in light of recent evidence that has emerged, as well as to address the lingering controversies about the original definition and grading of postoperative pancreatic fistula. The International Study Group of Pancreatic Fistula reconvened as the International Study Group in Pancreatic Surgery in order to perform a review of the recent literature and consequently to update and revise the grading system of postoperative pancreatic fistula. Based on the literature since 2005 investigating the validity and clinical use of the original International Study Group of Pancreatic Fistula classification, a clinically relevant postoperative pancreatic fistula is now redefined as a drain output of any measurable volume of fluid with an amylase level >3 times the upper limit of institutional normal serum amylase activity, associated with a clinically relevant development/condition related directly to the postoperative pancreatic fistula. Consequently, the former "grade A postoperative pancreatic fistula" is now redefined and called a "biochemical leak," because it has no clinical importance and is no longer referred to a true pancreatic fistula. Postoperative pancreatic fistula grades B and C are confirmed but defined more strictly. In particular, grade B requires a change in the postoperative management; drains are either left in place >3 weeks or repositioned through endoscopic or percutaneous procedures. Grade C postoperative pancreatic fistula refers to those postoperative pancreatic fistula that require reoperation or lead to single or multiple organ failure and/or mortality attributable to the pancreatic fistula. This new definition and grading system of postoperative pancreatic fistula should lead to a more universally consistent evaluation of operative outcomes after pancreatic operation and will allow for a better comparison of techniques used to mitigate the rate and clinical impact of a pancreatic fistula. Use of this updated classification will also allow for more precise comparisons of surgical quality between surgeons and units who perform pancreatic surgery. Copyright © 2016 Elsevier Inc.

Use of arteriovenous fistulas, the most preferred type of access for hemodialysis, is limited by their high maturation failure rate. The aim of this study was to assess whether aggressive surveillance with routine duplex ultrasound and intervention can decrease the maturation failure rate of arteriovenous fistulas. We conducted a single-center, parallel-group, randomized, controlled trial of patients undergoing autogenous arteriovenous fistula. Patients were randomly assigned (1:1) to either the routine duplex or selective duplex group. In the routine duplex group, duplex ultrasound and physical examination were performed 2, 4, and 8 weeks postoperatively. In the selective duplex group, duplex examination was performed only when physical examination detected an abnormality. The primary end point was the maturation failure rate 8 weeks after fistula creation. Maturation failure was defined as the inability to achieve clinical maturation ( i.e. , a successful first use) and failure to achieve sonographic maturation (fistula flow >500 ml/min and diameter >6 mm) within 8 weeks. Between June 14, 2012, and June 25, 2014, 150 patients were enrolled (75 patients in each group), and 118 of those were included in the final analysis. The maturation failure rate was lower in the routine duplex group (8 of 59; 13.6%) than in the selective duplex group (15 of 59; 25.4%), but the difference was not statistically significant (odds ratio, 0.46; 95% confidence interval, 0.18 to 1.19; P =0.10). Factors associated with maturation failure were women (odds ratio, 3.84; 95% confidence interval, 1.05 to 14.06; P =0.04), coronary artery disease (odds ratio, 6.36; 95% confidence interval, 1.62 to 24.95; P <0.01), diabetes (odds ratio, 6.10; 95% confidence interval, 1.76 to 21.19; P <0.01), and the preoperative cephalic vein diameter (odds ratio, 0.30; 95% confidence interval, 0.13 to 0.71; P <0.01). Postoperative routine duplex surveillance failed to prove superiority compared with selective duplex after physical examination for reducing arteriovenous fistula maturation failure. However, the wide 95% confidence interval for the effect of intervention precludes a firm conclusion that routine duplex surveillance was not beneficial.

We have devised a modified seton technique that resects the external fistula tract while preserving the anal sphincter muscle. This study assessed the technique when used for the management of complex anal fistulas. Between January 2006 and December 2007, 239 patients (208 males and 31 females, median age: 41 years) underwent surgery for complex anal fistulas using the technique. Of the 239 patients, 198 patients had trans-sphincteric fistula and 41 patients had supra-sphincteric fistula. The durations of the surgeries were 17 min (47, 13) [median (range, interquartile range)] for trans-sphincteric fistulas and 38 (44, 16) for supra-sphincteric fistulas. The durations of the surgeries were significantly (P < 0.05) longer for supra-sphincteric fistula than trans-sphincteric fistula. The hospital stays were 4 (13, 2) days and 5 (14, 3) days, respectively, for trans- and supra-sphincteric fistulas. The durations of seton placement until the spontaneous dropping of the seton were 42 (121, 48) and 141 (171, 55) days respectively. The recurrence rate was 0 % in patients with trans-sphincteric fistulas and 4.9 % (2 of 41) in patients with supra-sphincteric fistulas (P < 0.01). Serious incontinence was not observed. The technique provided favorable results for the treatment of complex anal fistulas and could be safely applied while preserving the sphincter function and conserving fecal continence.

Rectourethral fistulas are a rare but devastating complication of pelvic surgery and radiation. We review, analyze and describe the management and outcomes of nonradiated and radiation/ablation induced rectourethral fistulas during a consecutive 12-year period. We performed a retrospective review of patients undergoing rectourethral fistula repair between January 1, 1998 and December 31, 2009. Patient demographics as well as preoperative, operative and postoperative data were obtained. All rectourethral fistulas were repaired using an anterior transperineal approach with a muscle interposition flap and selective use of a buccal mucosal graft urethral patch onlay. A total of 74 patients with rectourethral fistulas underwent repair with an anterior perineal approach and muscle interposition flap (68 gracilis muscle interposition flaps, 6 other muscle interposition flaps). We compared 35 nonradiated and 39 radiated/ablation induced rectourethral fistulas. Concurrent urethral strictures were present in 11% of nonradiated and 28% of radiated/ablation rectourethral fistulas. At a mean followup of 20 months 100% of nonradiated rectourethral fistulas were closed with 1 procedure while 84% of radiated/ablation rectourethral fistulas were closed in a single stage. Of the patients with nonradiated rectourethral fistulas 97% had the bowel undiverted. Of those undiverted cases 100% were without bowel complication. Of the patients with radiated/ablation rectourethral fistulas 31% required permanent fecal diversion. Successful rectourethral fistula closure can be achieved for nonradiated (100%) and radiation/ablation (84%) rectourethral fistulas using a standard anterior perineal approach with an interposition muscle flap and selective use of buccal mucosal graft, providing a standard for rectourethral fistula repair. Even the most complex radiation/ablation rectourethral fistula can be repaired avoiding permanent urinary and fecal diversion.

Multiple factors and comorbidities have been implicated in the ability of arteriovenous fistulas (AVF) to mature, including vessel anatomy, advanced age, and the presence of coronary artery disease or peripheral vascular disease. However, little is known about the role of uremia on AVF primary failure. In this study, we attempt to evaluate the effect of uremia on AVF maturation by comparing AVF outcomes between pre-dialysis chronic kidney disease (CKD) stage five patients and those who had their AVF created after hemodialysis (HD) initiation. We included 612 patients who underwent AVF creation between 2003 and 2015 at the University of Miami Hospital and Jackson Memorial Hospital. Effects of uremia on primary failure were evaluated using univariate statistical comparisons and multivariate logistic regression analyses. Primary failure occurred in 28.1% and 26.3% of patients with an AVF created prior to or after HD initiation, respectively (p = 0.73). The time of HD initiation was not associated with AVF maturation in multivariate logistic regression analysis (p = 0.57). In addition, pre-operative blood urea nitrogen (p = 0.78), estimated glomerular filtration rate (p = 0.66), and serum creatinine levels (p = 0.14) were not associated with AVF primary failure in pre-dialysis patients. Our results show that clearance of uremia with regular HD treatments prior to AVF creation does not improve the frequency of vascular access maturation.

Enterocutaneous fistulas: an overview.

Enterocutaneous fistulas remain a difficult management problem. The basis of management centers on the prevention and treatment of sepsis, control of fistula effluent, and fluid and nutritional support. Early surgery should be limited to abscess drainage and proximal defunctioning stoma formation. Definitive procedures for a persistent fistula are indicated in the late postoperative period, with resection of the fistula segment and reanastomosis of healthy bowel. Even more complex are the enteroatmospheric fistulas in the open abdomen. These enteric fistulas require the highest level of multidisciplinary approach for optimal outcomes.

Urethrocutaneous fistula, which occurs after hypospadias surgery, is often a baffling problem and its treatment is challenging. The study aimed to evaluate the results of the simple procedure (Durham Smith vest-over-pant technique) for this complex problem (post-hypospadias repair fistula). During the period from 2011 to 2015, 20 patients with post-hypospadias repair fistulas underwent Durham Smith repair. Common age group was between 5 and 12 years. Site wise distribution of fistula was coronal 2 (10%), distal penile 7 (35%), mid-penile 7 (35%), and proximal-penile 4 (20%). Out of 20 patients, 15 had fistula of size <5 mm (75%) and 5 patients had fistula of size >5 mm (25%). All cases were repaired with Durham Smith vest-over-pant technique by a single surgeon. In case of multiple fistulas adjacent to each other, all fistulas were joined to form single fistula and repaired. We have successfully repaired all post-hypospadias surgery urethrocutaneous fistulas using the technique described by Durham Smith with 100% success rate. Durham Smith vest-over-pant technique is a simple solution for a complex problem (post hypospadias surgery penile fistulas) in properly selected patients. © 2017 S. Karger AG, Basel.

Tridimensional endoanal ultrasonography (3D-EAUS) has been used for the assessment of various anorectal lesions. Previous studies have reported good accuracy of 3D-EAUS in preoperative assessment of fistula-in-ano (FIA). This study aimed to assess the diagnostic utility of 3D-EAUS in preoperative evaluation of primary and recurrent FIA and its role in detection of associated anal sphincter (AS) defects. Prospectively collected data of patients with FIA who were investigated with 3D-EAUS were reviewed. The findings of EAUS were compared with the intraoperative findings, the reference standard, to find the degree of agreement regarding the position of the internal opening (IO) and primary tract (PT), and presence of secondary tracts using kappa (k) coefficient test. A subgroup analysis was performed to compare the accuracy and sensitivity of EAUS for primary and recurrent FIA. Of the patients, 131 were included to the study. EAUS had an overall accuracy of 87, 88.5, and 89.5% in detection of IO, PT, and AS defects, respectively. There was very good concordance between the findings of EAUS and intraoperative findings for the investigated parameters (kappa = 0.748, 0.83, 0.935), respectively. Accuracy and sensitivity of EAUS in recurrent FIA were insignificantly lower than primary cases. EAUS detected occult AS defects in 5.3% of the patients studied. The diagnostic utility of 3D-EAUS was comparable in primary and recurrent FIA. 3D-EAUS was able to detect symptomatic and occult AS defects with higher accuracy than clinical examination.

A patient with extensive burns was intubated with an 8.0 mm internal diameter endotracheal tube (ETT) equipped with a subglottic suction port (Mallinckrodt HiLo Evac). The ETT was secured to a left upper molar with wire sutures throughout the hospitalization course to ensure airway stability. On the 40th day of intubation, the patient exsanguinated and died from a tracheo-innominate artery fistula. Postmortem examination revealed a 1 cm lesion of the left anterior tracheal wall at the position of the ETT tip. The prolonged stationary position of the ETT was considered the primary factor responsible for the fistula. Yet tracheo-innominate artery fistula normally is associated with high cuff pressures rather than with the tube tip. The special ETT construction required for the subglottic suction feature was suspected to have increased tube rigidity and may have played a contributory role. The rigidity of the Mallinckrodt HiLo Evac was measured with a mechanical model and compared to 5 other commercially-available ETTs. Rigidity was expressed as the force generated by the ETT tip when the tube curvature was altered by 5 cm and 10 cm of flexion from its resting position. The mean force exerted by the Mallinckrodt HiLo Evac was 10.1 +/- 2.8 g at 5 cm of flexion and 17.7 +/- 5.1 g at 10 cm of flexion. This was significantly greater than all other ETT brands tested (by one-way analysis of variance and Student-Newman-Kuels test, p < 0.05). This case of fatal tracheo-innominate artery fistula formation associated with an ETT tip was unusual because of the extended duration of endotracheal intubation and the complexity of the patient's airway management problems. Our data suggest that the higher rigidity of the HiLo Evac ETT may have contributed to fistula development at the tube tip. However, we do not believe that the higher rigidity of the HiLo Evac ETT necessarily poses any greater risk than other ETTs under normal circumstances, in which the tube tip is not fixed in a stationary position for an extended period.

A substantial number of patients with autologous arteriovenous fistulas (AVFs) develop diffuse aneurysmal degeneration, which frequently interferes with successful access. These AVFs are often deemed unsalvageable. We hypothesize that long-segment plication in these patients can be performed safely with acceptable short-term AVF salvage rates. We reviewed a prospectively maintained database to identify all patients with extensive AVF aneurysmal disease operated on for this problem. Thirty-five patients, 25 (71%) male and 10 (29%) female were operated on between July 2012 and January 2014. AVFs included 23 (66%) brachiocephalic, 5 (14%) radiocephalic, and 7 brachiobasilic (20%) fistulae (one first stage only but in use). The cohort had one or a combination of local pain, arm edema, cannulation issue, recurrent thrombosis, dysfunctional during dialysis, or extreme tortuousity. Time range for AVF creation to consultation ranged from 3 months to 11 years. All underwent long-segment plication over a 20-Fr Bougie with or without segmental vein resection; 3 underwent concomitant first rib resection for costoclavicular stenosis; 21 patients had tunneled catheter placement for use while healing, whereas 13 were allowed segmental use of their AVF during the perioperative period (1 patient was not yet on dialysis). Early in our experience, AVFs were left under the wound, whereas all but one repaired since early 2013 were left under a lateral flap. All patients were followed by clinical examination and duplex. In the 30-day postoperative period, 2 AVFs (5.7%) became infected requiring excision, 2 occluded (5.7%), 1 day 1 and the other at 24 days out, 1 patient developed steal and required DRIL 1 week postoperatively, and 1 patient died, unrelated to his surgery. Postoperative functional primary patency was 88% (30 of 34). Of the patients needing temporary access catheter, mean time to first fistula use was 44 days. No wound or bleeding complications have occurred in repaired AVF left under skin flaps. In this group of patients whose access was threatened by diffuse aneurysmal degeneration, long-segment placation allowed salvage of 88% of fistulae with relatively low morbidity. Fewer complications are associated by covering the revised fistula with intact skin. Copyright © 2015 Elsevier Inc. All rights reserved.

Intimal hyperplasia and stenosis are often cited as causes of arteriovenous fistula maturation failure, but definitive evidence is lacking. We examined the associations among preexisting venous intimal hyperplasia, fistula venous stenosis after creation, and clinical maturation failure. The Hemodialysis Fistula Maturation Study prospectively observed 602 men and women through arteriovenous fistula creation surgery and their postoperative course. A segment of the vein used to create the fistula was collected intraoperatively for histomorphometric examination. On ultrasounds performed 1 day and 2 and 6 weeks after fistula creation, we assessed fistula venous stenosis using pre-specified criteria on the basis of ratios of luminal diameters and peak blood flow velocities at certain locations along the vessel. We determined fistula clinical maturation using criteria for usability during dialysis. Preexisting venous intimal hyperplasia, expressed per 10% increase in a hyperplasia index (range of 0%-100%), modestly associated with lower fistula blood flow rate (relative change, -2.5%; 95% confidence interval [95% CI], -4.6% to -0.4%; P =0.02) at 6 weeks but did not significantly associate with stenosis (odds ratio [OR], 1.07; 95% CI, 1.00 to 1.16; P =0.07) at 6 weeks or failure to mature clinically without procedural assistance (OR, 1.07; 95% CI, 0.99 to 1.15; P =0.07). Fistula venous stenosis at 6 weeks associated with maturation failure (OR, 1.98; 95% CI, 1.25 to 3.12; P =0.004) after controlling for case mix factors, dialysis status, and fistula location. These findings suggest that postoperative fistula venous stenosis associates with fistula maturation failure. Preoperative venous hyperplasia may associate with maturation failure but if so, only modestly. Copyright © 2017 by the American Society of Nephrology.

The use of dural grafts is very useful when primary dural closure cannot be achieved. Our primary objective was to study the incidence of postoperative cerebrospinal fluid leak, including fistula and pseudomeningocele, and postoperative infection by comparing autologous material and a new collagen graft. A prospective nonrandomized study with a new collagen-based product derived from porcine cells (Peridry) was performed. It was used for dural replacement in 50 patients who underwent a variety of neurosurgical procedures requiring the use of a dural graft. These results were compared with a control group of 50 patients who were treated with autologous duraplasty material. The follow-up period was 3 months. Postoperative overall cerebrospinal fluid fistula occurred in 6% of both groups. No patient in the collagen group developed any sort of infection. One patient in the control developed osteomyelitis in the bone flap. The new collagen-based product derived from porcine cells (Peridry), compared with an autologous tissue, is safe, effective, easy to use, as well as time saving in cranial neurosurgery.

Negative Pressure Wound Therapy for the Treatment of the Open Abdomen and Incidence of Enteral Fistulas: A Retrospective Bicentre Analysis

PubMed Central

Dold, Stefan; Doberauer, Johannes P.; Mai, Peter

2013-01-01

Introduction. The open abdomen (OA) is often associated with complications. It has been hypothesized that negative pressure wound therapy (NPWT) in the treatment of OA may provoke enteral fistulas. Therefore, we analyzed patients with OA and NPWT with special regard to the occurrence of intestinal fistulas. Methods. The present study included all consecutive patients with OA treated with NWPT from April 2010 to August 2011 in two hospitals. Patients' demographics, indications for OA, risk factors, complications, outcome and incidence of fistulas before, during and after NPWT were recorded. Results. Of 81 patients with OA, 26 had pre-existing fistulas and 55 were free from a fistula at the beginning of NPWT. Nine of the 55 patients developed fistulas during (n = 5) or after NPWT (n = 4). Seventy-five patients received ABThera therapy, 6 patients other temporary abdominal closure devices. Only diverticulitis seemed to be a significant predisposing factor for fistulas. Mortality was slightly lower for patients without fistulas. Conclusion. The present study revealed no correlation between occurrence of fistulas before, during, and after NWPT, with diverticulitis being the only risk factor. Fistula formation during NPWT was comparable to reports from literature. Prospective studies are mandatory to clarify the impact of NPWT on fistula formation. PMID:24285953

The aim of this study was to evaluate the success rate of urethrocutaneous fistula repair using buccal mucosal graft in patients with a previous hypospadias repair. We reviewed records of our patients with urethrocutaneous fistula developed after hypospadias repair in whom buccal mucosal graft fistula repair had been performed. All of the patients had been followed up for 24 postoperative months. A successful surgical operation was defined as no fistula recurrence or urethral stricture. Retrograde urethrography and urethrocystoscopy would be performed in patients who had any history of decreased force and caliber of urine or any difficulty in urination. Fistula repair using buccal mucosa patch graft had been done in 14 children with urethrocutaneous fistula developing after hypospadias reconstruction. The mean age of the children was 8.70 +/- 1.99 years old (range, 4 to 11 years). Seven fistulas were in the midshaft, 4 were in the penoscrotal region, and 3 were in the coronal region. Repair of the fistulas was successful in 11 of 14 patients (78.6%). In the remaining children, the diameter of the fistula was smaller than that before the operation, offering a good opportunity for subsequent closure. Our findings showed that fistula repair using buccal mucosal graft can be one of the acceptable techniques for repairing fistulas developed after hypospadias repair.

The development of de novo dural arteriovenous fistula(s) following endovascular embolization of a prior high-flow pial arteriovenous fistula (PAVF) has not previously been reported and the natural history is unknown. The anatomic basis, pathophysiologic mechanism, management and outcome are discussed. Treatment-completed congenital PAVFs treated at our center between January 2005 and August 2011 were analyzed retrospectively. Among 16 cases of PAVFs treated by endovascular embolization, four developed de novo dural arteriovenous fistulas during treatment or on follow-up that were not present before treatment. Information was collected from the clinical case records, imaging by MRI on presentation and during follow-up, all angiographic images and records during each of the procedures and during follow-up. The time interval between the last embolization and identification of a dural fistula ranged from 3 to 14 months. Ten fistulas were identified in four patients, seven of which were embolized, four with glue, two with Onyx18 and one with absolute alcohol. None recanalized, while one patient developed fistula in an adjacent location that was subsequently treated with radiosurgery. Not all fistulas need treatment; small fistulas with a minimal flow can safely be observed. De novo dural fistulas following endovascular embolization of high-flow PAVFs is not an uncommon development. They are mostly asymptomatic and develop anywhere along the drainage of the fistula, maturing over time and diagnosed during follow-up studies, emphasizing the need for follow-up angiography. They can be effectively treated by endovascular embolization. Localized refractory dural fistulas can be dealt with by radiosurgery.

One of the complications of pancreatic disease is the formation of pancreatic fistulae. The presence of fistula leads to body wasting and cachexia. The standard treatment is intubation of the Wirsung duct and in cases where there are no improvements the next proposed form of treatment is surgery. The aim of the study was to evaluate the efficacy of pancreatic fistula closure using interventional radiology techniques. In 2009 to 2014, 46 patients diagnosed with pancreatic fistula were treated with interventional radiology techniques. Treatment consisted of vascular coil implanted at the entry of the fistula and then sealed with tissue glue adhesive during endoscopic procedure. Technical success of vascular coil implantation and the use of tissue glue adhesive were reported in all patients. Pancreatic fistula recurred in 7 patients (15.2%). The latter group of patients underwent statistical analysis to determine what the risk factors in recurring pancreatic fistulas were. The results indicate a significant relationship between etiology of the fistula and treatment effect. (1) the use of interventional radiology methods in the closure of pancreatic fistula is an effective and safe procedure; and (2) the recurrence of fistula is dependent on the etiology and often occurs after surgery or trauma.

Perioperative management of infants with esophageal atresia and tracheoesophageal fistula (EA/TEF) is frequently based on surgeon experience and dogma rather than evidence-based guidelines. This study examines whether commonly perceived important aspects of practice affect outcome in a contemporary multi-institutional cohort of patients undergoing primary repair for the most common type of esophageal atresia anomaly, proximal EA with distal TEF. The Midwest Pediatric Surgery Consortium conducted a multicenter, retrospective study examining selected outcomes on infants diagnosed with proximal EA with distal TEF who underwent primary repair over a 5-year period (2009-2014), with a minimum 1-year follow up, across 11 centers. 292 patients with proximal EA and distal TEF who underwent primary repair were reviewed. The overall mortality was 6% and was significantly associated with the presence of congenital heart disease (OR 4.82, p=0.005). Postoperative complications occurred in 181 (62%) infants, including: anastomotic stricture requiring intervention (n=127; 43%); anastomotic leak (n=54; 18%); recurrent fistula (n=15; 5%); vocal cord paralysis/paresis (n=14; 5%); and esophageal dehiscence (n=5; 2%). Placement of a transanastomotic tube was associated with an increase in esophageal stricture formation (OR 2.2, p=0.01). Acid suppression was not associated with altered rates of stricture, leak or pneumonia (all p>0.1). Placement of interposing prosthetic material between the esophageal and tracheal suture lines was associated with an increased leak rate (OR 4.7, p<0.001), but no difference in the incidence of recurrent fistula (p=0.3). Empiric postoperative antibiotics for >24h were used in 193 patients (66%) with no difference in rates of infection, shock or death when compared to antibiotic use ≤24h (all p>0.3). Hospital volume was not associated with postoperative complication rates (p>0.08). Routine postoperative esophagram obtained on day 5 resulted in no delayed/missed anastomotic leaks or a difference in anastomotic leak rate as compared to esophagrams obtained on day 7. Morbidity after primary repair of proximal EA and distal TEF patients is substantial, and many common practices do not appear to reduce complications. Specifically, this large retrospective series does not support the use of prophylactic antibiotics beyond 24h and empiric acid suppression may not prevent complications. Use of a transanastomotic tube was associated with higher rates of stricture, and interposition of prosthetic material was associated with higher leak rates. Routine postoperative esophagram can be safely obtained on day 5 resulting in earlier initiation of oral feeds. Treatment study. III. Copyright © 2017 Elsevier Inc. All rights reserved.

CSF Venous Fistulas in Spontaneous Intracranial Hypotension: Imaging Characteristics on Dynamic and CT Myelography.

The objective of this study is to describe the anatomic and imaging features of CSF venous fistulas, which are a recently reported cause of spontaneous intracranial hypotension (SIH). We retrospectively reviewed the records of patients with SIH caused by CSF venous fistulas who received treatment at our institution. The anatomic details of each fistula were recorded. Attenuation of the veins involved by the fistula was compared with that of adjacent control veins on CT myelography (CTM). Visibility of the CSF venous fistula on CTM and a modified conventional myelography technique we refer to as dynamic myelography was also compared. Twenty-two cases of CSF venous fistula were identified. The fistulas were located between T4 and L1. Ninety percent occurred without a concurrent epidural CSF leak. In most cases (82%), the CSF venous fistula originated from a nerve root sleeve diverticulum. On CTM, the abnormal veins associated with the CSF venous fistula were seen in a paravertebral location in 45% of cases, centrally within the epidural venous plexus in 32%, and lateral to the spine in 23%. Differences in attenuation between the fistula veins and the control veins was highly statistically significant (p < 0.0001), with a threshold of 70 HU perfectly discriminating fistulas from normal veins in our series. When both CTM and dynamic myelography were performed, the fistula was identified on both modalities in 88% of cases. CSF venous fistulas are an important cause of SIH that can be detected on both CTM and dynamic myelograph y and may occur without an epidural CSF leak. Familiarity with the imaging characteristics of these lesions is critical to providing appropriate treatment to patients with SIH.

Complicating causality: patient and professional perspectives on obstetric fistula in Nigeria.

Obstetric fistula, a preventable maternal morbidity characterised by chronic bladder and/or bowel incontinence, is widespread in Nigeria. This qualitative, multi-site study examined the competing narratives on obstetric fistula causality in Nigeria. Research methods were participant observation and in-depth interviews with 86 fistula patients and 43 healthcare professionals. The study found that both patient and professional narratives identified limited access to medical facilities as a major factor leading to obstetric fistula. Patients and professionals beliefs regarding the access problem, however, differed significantly. The majority of fistula patients reported either delivering or attempting to deliver in medical facilities and most patients attributed fistula to a lack of trained medical staff and mismanagement at medical facilities. Conversely, a majority of health professionals believed that women developed obstetric fistula because they chose to deliver at home due to women's traditional beliefs about womanhood and childbirth. Both groups described financial constraints and inadequate transport to medical facilities during complicated labour as related to obstetric fistula onset. Programmatic insights derived from these findings should inform fistula prevention interventions both with healthcare professionals and with Nigerian women.

to explore the cultural, social and economic needs and challenges of women in northern Ghana as they resume their day-to-day lives post obstetric fistula repair. a critical ethnographic approach. a state run fistula treatment center in Tamale, northern Ghana, and 24 rural communities in northern Ghana. ninety-nine (N=99) participants were recruited using purposive, convenience and snowball sampling. The sample consisted of women (N=41) who had experienced an obstetric fistula repair and their family members (N=24). Health care providers (N=17) and stakeholders (N=17) who had specialised knowledge about reintegration programs at a community or national level were also included. the needs and challenges of northern Ghanaian women post obstetric fistula repair were historically and culturally rooted. A woman's psychosocial acceptance back into her community post obstetric fistula was significant to her well-being but many women felt they had to 'prove' themselves worthy of acceptance and hid any signs of urinary incontinence post obstetric fistula repair. The cost of treatment compounded by a woman's inability to work while having the obstetric fistula exaggerated her economic needs. Skills training programs offered assistance but were often not suited to a woman's physical capability or geographic location. Many women who have experienced obstetric fistula along with women leaders have initiated obstetric fistula awareness campaigns in their communities with the aim of overcoming the challenges and improving the reintegration experiences of others who have had an obstetric fistula repair. developing understanding about the needs and challenges of women post obstetric fistula is an important step forward in creating social and political change in obstetric fistula care and reintegration. Strategies to support women reintegrating to their communities post obstetric fistula repair include exploring alternative forms of skills training and income generation activities, creating innovative pre and post obstetric fistula health education and community awareness to reduce the perception of the condition as 'incurable', and promoting peer advocacy.

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

Administration of ε-aminocaproic acid (εACA), as adjuvant therapy following incompletely embolized cranial dural arteriovenous (dAVFs) and direct carotid artery to cavernous sinus fistulae (CCFs), is a strategy to promote post-procedural thrombosis. However, the efficacy of εACA to treat incompletely obliterated dAVFs and CCFs has not been published. The purpose of this study was to determine if administration of εACA following incomplete embolization of cranial dAVFs or CCFs was associated with an increased likelihood of cure on follow-up imaging compared with patients not given adjuvant εACA. A retrospective cohort study was performed. All patients who underwent treatment of a dAVF or CCF at our institution between 1998 and 2016 were reviewed (n=262). Patients with residual shunting following the first attempted endovascular embolization were included in the analysis (n=52). The study groups were those treated with εACA following incomplete obliteration of the fistula and those who were not. The primary outcome was obliteration of the fistula on initial follow-up imaging. Complication rates between cohorts were compared. 20 (38%) patients with incompletely obliterated fistulae were treated with adjuvant εACA. A trend towards an improved rate of complete obliteration on initial follow-up imaging was observed in the group treated with εACA (55% vs 34% in the group not treated with εACA, p=0.14). No difference in clinical outcomes or thromboembolic complications was observed between the groups. In summary, these data suggest that administration of εACA is a safe adjuvant therapy in the management of cranial dAVFs and CCFs that are incompletely treated endovascularly. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

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

Females with Krickenbeck low-type anorectal malformations - vestibular fistula (VF) and perineal fistula (PF) - are managed either by a primary definitive or conventional three-staged approach. Ultimate outcome in these children may be affected by wound dehiscence leading to healing by fibrosis. Most of the literature favors one approach over other based on retrospective analysis of their outcomes. Whether a statistically significant difference in wound dehiscence rates between these approaches exists needed to be seen. A randomized controlled trial for girls <14 years with VF or PF was done. Random tables were used to randomize 33 children to Group I (primary procedure) and 31 to Group II (three-staged procedure). Statistical analysis was done for significance of difference ( P < 0.05) in the primary outcome (wound dehiscence) and secondary outcomes (immediate and early postoperative complications). Of the 64 children randomized, 54 (84%) had VF. Both groups were comparable in demography, clinical profile and age at surgery. The incidence of wound dehiscence (39.4% vs. 18.2%; P = 0.04), immediate postoperative complications (51.5% vs. 12.9%; P = 0.001), and early postoperative complications (42.4% vs. 12.9%; P = 0.01) was significantly higher in Group I as compared to Group II. Six of 13 children (46.2%) with dehiscence in Group I required a diverting colostomy to be made. Females with VF or PF undergoing primary definitive procedure have a significantly higher incidence of wound dehiscence ( P = 0.04), immediate ( P = 0.001) and early postoperative complications ( P = 0.01).

Fistula Isolation and the Use of Negative Pressure to Promote Wound Healing: A Case Study.

PubMed

Reider, Kersten E

A 54-year-old morbidly obese woman with a small bowel obstruction and large ventral hernia was admitted to hospital. She underwent an exploratory laparotomy, lysis of adhesions, and ventral hernia repair with mesh placement. She subsequently developed an enteroatmospheric fistula; several months of hospital care was required to effectively manage the wound and contain effluent from the fistula. Several approaches were used to manage output from the fistula during her hospital course. She was initially discharged to a skilled nursing facility where a fistula management pouch was used for several months to encompass the wound and contain effluent, but this method ultimately proved ineffective. The fistula was then isolated using a collapsible enteroatmospheric fistula isolation device and an ostomy appliance to contain effluent. The application of the collapsible enteroatmospheric fistula isolation and effluent containment devices in conjunction with negative-pressure wound therapy produced positive patient outcomes; it improved patient satisfaction with fistula management, promoted wound healing, and diminished cost.

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

Pancreatic fistula is the most common complication following distal pancreatectomy. We have developed a fibrin adhesive sealing method which covers the cut surface and parenchyma of the pancreas, to prevent pancreatic fistula. We performed 25 distal pancreatectomies. Fibrin adhesive (TachoComb) was applied to the staple line of the pancreas before stapling. Pancreatic fistula was defined and graded according to the International Study Group of Postoperative Pancreatic Fistula (ISGPF) definition. The overall incidence of pancreatic fistula was five cases (20%). Four cases (16%) were classified as Grade A. Only one case (4%) was classified as Grade B. In patients with or without pancreatic fistula, the mean length of postoperative hospital stay was not significant. The fibrin adhesive sealing method is a simple and effective method of preventing postoperative pancreatic fistula formation after distal pancreatectomy.

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

Experience of flow control techniques during endovascular treatment of intracranial dural arteriovenous fistulas (DAVFs) using the Onyx liquid embolic system is reported, with an emphasis on high flow shunts. Data were evaluated in patients with DAVFs treated endovascularly with Onyx. Adjunctive techniques with coils, acrylics and balloon assistance were utilized to reduce the rate of flow with transarterial and transvenous approaches. The following types of adjunctive techniques were used in 58 patients who underwent a total of 84 embolization sessions with Onyx: transvenous coiling with transvenous or transarterial Onyx embolization in 36 patients, transarterial coiling with transarterial Onyx embolization in eight patients, arterial or venous balloon assisted technique with transarterial or transvenous Onyx embolization in 11 patients, transarterial high concentration acrylics with transarterial Onyx embolization in one patient and staged transarterial or transvenous coiling and Onyx embolization in two patients. Complete obliteration of the fistulae was achieved in 41 patients (70.7%) and 27 patients (65.9%) with high flow fistulae after endovascular treatment alone. Periprocedural complications were encountered in 16 patients, and 13 complications were associated with the adjunctive techniques. There were four neurologic and two non-neurologic clinical sequelae. Distal Onyx migration occurred in four, microcatheter retention in three and cranial neuropathy in three patients. There was one instance each of cerebellar hemorrhage, thromboembolism, coil stretching and retention, and dissection. 56 survivors experienced complete resolution or significant improvement of their symptoms on follow-up. Flow control techniques are safe and effective adjunctive methods in primary endovascular Onyx embolization of high flow DAVFs.

Evaluate the effect of topical application of autologous platelet-rich plasma (PRP) in primary repair of complete cleft palate and then compare the result with another group of patients using the same surgical technique, without application of PRP with regard to the incidence of oronasal fistula, velopharyngeal closure, and grade of nasality. Case control study. This study was carried on 44 children with complete cleft palate with age range from 12 to 23 months. The children were divided into two age- and gender-matched groups: All children were subjected to the same technique of V-Y pushback repair of the complete cleft palate. In group A (22 children), the PRP prepared from the patient was topically applied between the nasal and oral mucosa layer during palatoplasty, whereas in group B (22 children) the PRP was not applied. All cases were recovered smoothly without problems. In group A, no oronasal fistula was reported, whereas in group B three patients (13.6%) had postoperative fistulae and two patients (9.1%) needed revision palatoplasty. At 6 months postoperative assessment, group A (with PRP application) showed significantly better grade of nasality (P = 0.024) and better endoscopic velopharyngeal closure (P = 0.016) than group B. Usage of autologous PRP in complete cleft palate repair is simple; effective; can decrease the incidence of oronasal fistula; and also significantly improves the grade of nasality and velopharyngeal closure, which decreases the need of further surgical intervention in cleft palate patients. 3b.

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

2002-01-01

Enteric fistulas are nowadays considered an important therapeutic challenge. Artificial, total parenteral and enteral nutrition have allowed an improvement in the healing of these fistulas and a lower incidence of mortality. Fourteen patients with enteric fistulas (10 men, 4 women; mean age: 64.4 years; range: 20-80 years) were observed. The fistula was located in the large bowel in 11 patients, in the ileum in 2, and in the jejunum in 1. Thirteen patients received enteral nutrition. The patient with the jejunal fistula received total parenteral nutrition for 30 days and then enteral nutrition. The fistulas were successfully treated in 11 patients. One patients underwent surgery after 6 weeks of treatment with enteral nutrition because of lack of improvement of the symptomatology. In two patients, with advanced cancer of the colon and stomach, respectively, only a reduction of the fistula output was achieved. Nutritional support in the treatment of enteric fistulas is an effective procedure widely utilised to restore adequate nutritional status and bowel rest, which are two important targets for achieving fistula closure. Nutritional support is also useful in the management of patients undergoing surgery in order to reduce the postoperative complication rate.

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

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

Optimal surgical treatment for anal fistula should result in healing of the fistula track and preserve anal continence. The aim of this study was to evaluate Permacol™ collagen paste (Covidien plc, Gosport, Hampshire, UK) injection for the treatment of complex anal fistulas, reporting feasibility, safety, outcome and functional results. Between May 2013 and December 2014, 21 consecutive patients underwent Permacol paste injection for complex anal fistula at our institutions. All patients underwent fistulectomy and seton placement 6-8 weeks before Permacol™ paste injection. Follow-up duration was 12 months. Eighteen patients (85.7%) had a high transsphincteric anal fistula, and three female patients (14.3%) had an anterior transsphincteric fistula. Fistulas were recurrent in three patients (14.3%). Seven patients (33%) had a fistula with multiple tracts. After a follow-up of 12 months, ten patients were considered healed (overall success rate 47.6%). The mean preoperative FISI score was 0.33 ± 0.57 and 0.61 ± 1.02 after 12 months. Permacol™ paste injection was safe and effective in some patients with complex anal fistula without compromising continence.

Female genital fistula remains a public health concern in developing countries. From January 2007 to September 2013, the Fistula Care project, managed by EngenderHealth in partnership with the Ministry of Health and supported by USAID, integrated fistula repair services in the maternity wards of general hospitals in Guinea. The objective of this article was to present and discuss the clinical outcomes of 7 years of work involving 2116 women repaired in three hospitals across the country. This was a retrospective cohort study using data abstracted from medical records for fistula repairs conducted from 2007 to 2013. The study data were reviewed during the period April to August 2014. The majority of the 2116 women who underwent surgical repair had vesicovaginal fistula (n = 2045, 97%) and 3% had rectovaginal fistula or a combination of both. Overall 1748 (83%) had a closed fistula and were continent of urine immediately after surgery. At discharge, 1795 women (85%) had a closed fistula and 1680 (79%) were dry, meaning they no longer leaked urine and/or faeces. One hundred and fifteen (5%) remained with residual incontinence despite fistula closure. Follow-up at 3 months was completed by 1663 (79%) women of whom 1405 (84.5%) had their fistula closed and 80% were continent. Twenty-one per cent were lost to follow-up. Routine programmatic repair for obstetric fistula in low resources settings can yield good outcomes. However, more efforts are needed to address loss to follow-up, sustain the results and prevent the occurrence and/or recurrence of fistula. © 2015 The Authors.

Arteriovenous (AV) fistulas are crucial in patients requiring long-term hemodialysis (HD). Dysfunctions of these fistulas are the most common causes of recurrent hospitalizations. This study aimed to evaluate the feasibility, safety and usefulness of contrast-enhanced magnetic resonance angiography (CE-MRA) in the evaluation of HD fistulas complications, and the condition of the central veins before HD access. This study comprised 30 consecutive patients (15 females, 15 males; age range 25-66 yrs, mean +/- SD 51.2 +/- 9.9 yrs). Of 30 patients, 26 had native AV fistulas and the remaining four patients, who had a history of previous subclavian vein catheterization, were candidates for HD fistulas. Nine patients had a radiocephalic fistula, 15 had a brachiobasilic fistula, one had a saphenous vein graft, and one had brachiobasilic vein transposition. To observe the fistula complications in these cases, three-dimensional (3-D) CE-MRA using gadolinium was performed. The results were considered normal in three patients (10%), who were candidates for AV fistula construction; one patient had central vein occlusion due to previous catheterization. Thirteen patients (43.3%) had venous stenosis or occlusion; three of them (10%) had low CE arteries distal to fistula region, leading to ischemic complications, and six (20%) had stenosis at the fistula region. Seven patients (23.3%) had venous pseudoaneurysms, whereas two of them had both pseudoaneurysms and fistula region stenosis, and one had both venous stenosis and pseudoaneurysm. There were no adverse or allergic-like reactions or heat and taste sensations observed in our series. 3-D CE-MRA is a useful, safe and a practical imaging modality in complicated fistula diagnosis with fewer complications and side-effects in comparison to fistulography.

In Western countries, tuberculous anal fistula may not be an issue because tuberculosis [TB] is not common, and this is a very rare form of extrapulmonary manifestation of TB. However in TB-endemic countries, careful diagnostic differentiation is required because the clinical features of TB anal fistula and Crohn's disease [CD] anal fistula are similar, with distinguishing features remaining unclear. We aimed to analyse the clinical features of TB versus CD anal fistulas. Among 13872 patients who underwent anal fistula surgery from 2003 to 2014, 87 patients with TB fistulas and 116 patients with CD fistulas were included. Data on the annual incidence of TB and CD, as well as the clinical, pathological, ultrasonographic, colonoscopic and surgical data were analysed. Compared with CD, the TB group was older [median: 37 vs 22 years] and underlying chronic illness was more common [20.3% vs 2.6%]. In the TB group, 46 patients [59.7%] showed active or inactive pulmonary TB, and acid-fast bacilli and caseating granuloma were found in 56.3% and 62.1%, respectively. During colonoscopy, mucosal lesions were observed more frequently in CD [96.9% vs 16.9%]. TB anal fistula is clinically very similar to CD anal fistula. In Korea, the incidence of CD anal fistula has recently increased in prevalence, whereas the prevalence of TB anal fistula is decreasing but is still persistent. We recommend that clinicians should prepare for a possibility of TB as well as CD anal fistula in TB-endemic countries including Korea.

This study was conducted to investigate the risk factors of anastomotic fistula after the radical resection of esophageal-cardiac cancer. Five hundred and forty-four esophageal-cardiac cancer patients who underwent surgery and had complete clinical data were included in the study. Fifty patients diagnosed with postoperative anastomotic fistula were considered the case group and the remaining 494 subjects who did not develop postoperative anastomotic fistula were considered the control. The potential risk factors for anastomotic fistula, such as age, gender, diabetes history, smoking history, were collected and compared between the groups. Statistically significant variables were substituted into logistic regression to further evaluate the independent risk factors for postoperative anastomotic fistulas in esophageal-cardiac cancer. The incidence of anastomotic fistulas was 9.2% (50/544). Logistic regression analysis revealed that female gender (P < 0.05), laparoscopic surgery (P < 0.05), decreased postoperative albumin (P < 0.05), and postoperative renal dysfunction (P < 0.05) were independent risk factors for anastomotic fistulas in patients who received surgery for esophageal-cardiac cancer. Of the 50 anastomotic fistulas, 16 cases were small fistulas, which were only discovered by conventional imaging examination and not presenting clinical symptoms. All of the anastomotic fistulas occurred within seven days after surgery. Five of the patients with anastomotic fistulas underwent a second surgery and three died. Female patients with esophageal-cardiac cancer treated with endoscopic surgery and suffering from postoperative hypoproteinemia and renal dysfunction were susceptible to postoperative anastomotic fistula. © 2017 The Authors.

Radiation therapy is an integral part of treatment for head and neck cancer, but its use is not without complications. We describe the first reported sternoclavicular-tracheal fistula resulting from osteoradionecrosis (ORN) at the medial clavicle. This ORN resulted from definitive radiation therapy for a primary pyriform sinus squamous cell carcinoma. The diagnosis of ORN was made by fiberoptic bronchoscopy. The physiologic damage of ORN is based on a compromised blood supply and altered metabolism of bone formation secondary to effects of ionizing radiation. Treatment requires meticulous hygiene, antibiotics, and debridement as conservative therapy. Radical surgery and reconstruction may be indicatedmore » in refractory cases. A thorough preirradiation assessment of patients is mandatory to decrease the incidence of radiation-induced ORN.« less

Carotid-cavernous fistulas are abnormal communications between carotid arteries or their branches and the cavernous system caused mostly by trauma. Posttraumatic fistulas represent 70% of all carotid-cavernous fistulas and they are mostly high-flow shunts (type A). This type gives characteristic eye symptoms. This paper presents a 44-year old male patient with carotid-cavernous fistula as a result of penetrating head injury. In clinical presentation the patient had exophthalmos, conjunctival chemosis and weakening of vision on the right eye, headache and diplopia. Digital subtracted angiography showed high-flow carotid-cavernous fistula, which was vascularised from the left carotid artery and from vertebrobasilar artery. Endovascular embolization with platinum coils was performed through the transarterial route (endoarterial approach). Check angiogram confirmed that the fistula was closed and that no new communications developed. Embolization of complex carotid-cavernous fistula type A was successfully performed with platinum coils by endovascular approach.

To evaluate the long-term clinical efficacy and safety of double-layered polytetrafluoroethylene membrane-covered self-expandable segmental metallic stents (Uventa) in patients with chronic ureteral obstruction. In a retrospective study, a total of 50 ureter units (44 patients) with chronic obstructions were included from July 2010 to May 2015. Indications for Uventa placement were primary stenting for malignant ureteral obstruction, failed conventional polymeric Double-J stent (PS), or percutaneous nephrostomy (PCN) technique, with comorbidities or fears limiting PS/PCN changes, or with irritation or pain due to PS/PCN. Patients underwent Uventa stent placement using the antegrade or retrograde approach. There were no immediate procedure-related complications, and all stents were placed in the proper sites. During the median follow-up of 30.9 (interquartile range [IQR], 8.1-49.0) months, the primary (no obstruction and no additional intervention) and overall success (no obstruction and no additional intervention except supplementary Uventa) was 30.0% and 34.0%, respectively. Moreover, 14 of 50 ureter units (28.0%) experienced major complications (≥Clavien-Dindo class IIIb), such as ureteroarterial fistula (three cases, 6.0%), ureteroenteric fistula (three, 6.0%), ureterovaginal fistula (one, 2.0%), ureter perforation (one, 2.0%), uncontrollable bleeding (one, 2.0%), and complete obstruction (five, 10.0%). On univariate analysis, major complications were associated with female (odds ratio [OR] = 6.000), cervical cancer (OR = 4.667), ureteral stricture length (≥6.0 cm, OR = 4.583), and placement duration (≥24.0 months, OR = 20.429; all p < 0.05). In long-term follow-up, the Uventa stent demonstrated poor treatment outcomes with frequent major complications in patients with chronic ureteral obstructions.

The formation of a fistula between the lacrimal sac and the skin is a classic outcome of resistant lacrimal sac abscesses. There is currently no consensus about treatment in such cases. The goal of this study was to describe the natural history of acquired fistulas between the lacrimal sac and the skin, occurring before planned endonasal dacryocystorhinostomy (DCR) and without any treatment of the fistula. This prospective study was only descriptive and included patients between 1999 and 2012. The patients included were adults with a nasolacrimal duct (NLD) obstruction that was planned to be treated with endonasal DCR. A resistant lacrimal sac abscess appeared a few days before the planned surgery, and fistulized spontaneously despite medical treatment. The surgery was not delayed. The DCR was endoscopic. Nothing was done for the fistula. Its healing was spontaneous. The exclusion criteria were the following: congenital fistulas, post-traumatic and/or iatrogenic fistulas, fistulas which had regressed by the day of the surgery, postoperative follow-up less than 5 months, post-traumatic and/or iatrogenic fistulas, any history of previous DCR or any other lacrimal surgery, children. Twenty adults (25 cases) were included in the analysis. Mean age was 79 years old (from 41 to 90). The mean follow-up was 41 months (from 5 to 108 months). The fistula spontaneously disappeared in all cases, less than one month after it had appeared and in a permanent fashion. No unsightly scar developed. Spontaneously acquired fistulas between the lacrimal sac and the skin may occur in the natural course of abscessed acute dacryocystitis. Our study showed spontaneous healing of the fistula post-endoscopic DCR. Fistula excision in fistulous acute dacryocystitis does not seem essential to its healing. The laisser-faire approach appears adequate for aesthetic outcomes as well as for functional outcomes of DCR. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

The aim of this study was to evaluate the effectiveness of Octreotide as an adjunct treatment to total parenteral nutrition in the spontaneous closure of postoperative enterocutaneous fistulas. Medical records of 39 patients with postoperative enterocutaneous fistulas treated in our Department between January 1988 and August 2000 were reviewed. Sixteen patients had duodenal fistulas and 23 had jejunal or ileal fistulas. According to the daily output, there were 20 low fistula output and 19 high fistula output. Conservative treatment consisted of nutritional support with total parenteral nutrition in all the patients. Administration of Octreotide (100 micrograms every 8 hours, subcutaneously) was done in 21 consecutive patients until spontaneous closure of the fistulas or their subsequent surgical closure. The occurrence of fistulas closure was compared using the Fisher's exact test. A mean reduction of 50% of fistula output was noted in all the patients who received Octreotide, within 24 hours of its administration. Spontaneous closure was achieved in 13 patients of the Octreotide group (mean closure time: 15.3 days, range: 6-35) and in 12 patients treated only with total parenteral nutrition (mean closure time: 13.9 days, range: 7-25); this difference was not significant (P = 0.5). Also, the fistula closure rate was not influenced by the anatomic site, the high or low output, and the age of the patient. The results of this study suggest that, as an adjunct treatment to total parenteral nutrition, Octreotide reduces rapidly the fistula output without significant influence in the spontaneous closure rate.

The Demographic and Health Surveys (DHS), which include standardised questions on female genital fistula symptoms, provide a unique opportunity to evaluate the epidemiology of fistula. This study sought to examine associations between self-reported fistula symptoms and experience of gender-based violence (GBV) among women interviewed in DHS surveys. This study used data from thirteen DHS surveys with standardised fistula and domestic violence modules. Data from the most recent survey in each country were pooled, weighting each survey equally. Multivariable logistic regressions controlled for maternal and demographic factors. Prevalence of fistula symptoms in this sample of 95 625 women ranges from 0.3% to 1.8% by country. The majority of women reporting fistula symptoms (56%) have ever experienced physical violence, and more than one-quarter have ever experienced sexual violence (27%), compared with 38% and 13% among women with no symptoms, respectively. Similarly, 16% of women with fistula symptoms report recently experiencing sexual violence-twice the percentage among women not reporting symptoms (8%). Women whose first experience of sexual violence was from a non-partner have almost four times the odds of reporting fistula symptoms compared with women who never experienced sexual violence. These associations indicate a need to investigate temporal and causal relationships between violence and fistula. The increased risk of physical and sexual violence among women with fistula symptoms suggests that fistula programmes should incorporate GBV into provider training and services. © 2017 The Authors.

Fistulizing Crohn's disease represents an evolving, yet unresolved, issue for multidisciplinary management. Perianal fistulas are the most frequent findings in fistulizing Crohn's disease. While enterocutaneous fistulas are rare, they are associated with considerable morbidity and mortality. Detailed evaluation of the fistula tract by advanced imaging techniques is required to determine the most suitable management options. The fundamentals of perianal fistula management are to evaluate the complexity of the fistula tract, and exclude proctitis and associated abscess. The main goals of the treatment are abscess drainage, which is mandatory, before initiating immunosuppressive medical therapy, resolution of fistula discharge, preservation of continence and, in the long term, avoidance of proctectomy with permanent stoma. The management of enterocutaneous fistulas comprises of sepsis control, skin care, nutritional optimization and, if needed, delayed surgery.

[Effects of nutritional support on the hypermetabolism of patients with digestive tract fistula].

2012-05-01

Digestive tract fistulas are abnormal connections between gastrointestinal tract and other organs that most commonly occur after surgery. Morbidity and mortality associated with postoperative fistulas are substantial as they are highly associated with nutritional deficits, hypermetabolism, septic complications and concomitant diseases that may appear during prolonged hospital stay. Digestive tract fistula is a challenging condition that involves a multidisciplinary approach to management. The main treatment includes intestinal rest,correction of electrolytic disturbances, parenteral nutrition,protection of the skin surrounding the fistula, and treatment and prophylaxis of any related local or systemic septic complications. Nutritional support, which is an effective and promising treatment for patients with digestive tract fistulas, can promote the closure of the fistula and decrease the duration of hospital stay.

2017-01-01

Abstract Background: Fistulae between the prostatic urethra and the rectum are rare. They may result from prostatic or rectal surgery. Predisposing factors are previous radiation or immunosuppression. The repair of such fistulae usually involves major surgery. Recently, clips that can be deployed over an endoscope have been developed to close gastrointestinal fistulae or access points for natural orifice surgery. We report the first case of effective treatment of a prostatorectal fistula with a rectal “over-the-scope” clip. Case Presentation: A 64-year-old man under chronic immunosuppression presented with an iatrogenic fistula between the prostatic urethra and the rectum after transurethral resection of the prostate. A transverse colostomy was placed but the fistula failed to heal conservatively. The fistula was effectively closed with an endorectal clip. Six weeks after the procedure, spontaneous micturition was started. Two weeks further, the colostomy was reversed. At 32 months of follow-up, the remains closed, micturition is unimpaired. Conclusion: In select cases of prostatorectal fistula, an endorectal clip may be effectively used for closure. PMID:29098198

Significant hemobilia due to arterio-biliary fistula is a very rare complication of chemoradiation therapy (CRT) for unresectable intrahepatic cholangiocarcinoma (ICC). Here we report a case of arterio-biliary fistula after CRT for unresectable ICC demonstrated by angiographic examinations. This fistula was successfully treated by endovascular embolization. Hemobilia is a rare complication, but arterio-biliary fistula should be considered after CRT of ICC. PMID:21160700

Management of enterocutaneous fistulas.

PubMed

Schecter, William P

2011-06-01

Management of enterocutaneous fistulas (ECFs) involves (1) recognition and stabilization, (2) anatomic definition and decision, and (3) definitive operation. Phase 1 encompasses correction of fluid and electrolyte imbalance, skin protection, and nutritional support. Abdominal imaging defines the anatomy of the fistula in phase 2. ECFs that do not heal spontaneously require segmental resection of the bowel segment communicating with the fistula and restoration of intestinal continuity in phase 3. The enteroatmospheric fistula (EAF) is a malevolent condition requiring prolonged wound care and nutritional support. Complex abdominal wall reconstruction immediately following fistula resection is necessary for all EAFs. 2011 Elsevier Inc. All rights reserved.

Urethrocutaneous fistulae after hypospadias repair: When do they occur?

PubMed

Liao, Adelene Y; Smith, Grahame Hh

2016-05-01

The aim is to determine the incidence and timing of urethrocutaneous fistula diagnosis after hypospadias surgery. A retrospective review of all patients who had both initial hypospadias surgery and subsequent fistula repair from 1995 to 2012. A comparison was made between patients who had an initial onlay island flap procedure and those who had a tubularised incised plate repair. Patient age at initial surgery ranged from 6 months to 16 years of age. The median time to fistula presentation was 8.5 months with a range of less than 1 month to 13.9 years post-hypospadias surgery. The median time to fistula repair was 17 months. The overall fistula rate was 8%. There was no significant difference between the rates of fistulae for onlay island flap (9%) versus tubularised incised plate procedure (7%). Urethrocutaneous fistulae can present many years after the original hypospadias repair. The majority are diagnosed within the first year after surgery. Rates of fistulae are probably underreported due to short follow-up, but more importantly, due to patients transferring to other surgeons for fistula repair. © 2016 The Author Journal of Paediatrics and Child Health © 2016 Paediatrics and Child Health Division (Royal Australasian College of Physicians).

Enterocutaneous fistula: a review of 82 cases.

Enterocutaneous fistula is an unpleasant and troublesome complication of abdominal operations. The objective was to review the outcome of treatment of patients treated for enterocutaneous fistula. This is a retrospective study of 82 teenage and adult patients, who suffered from enterocutaneous fistula, seen over an 11 year period, in the University of Nigeria Teaching Hospital, Enugu. Patients' charts were reviewed for biodata, etiology of the fistula, volume of the fistula output, and result of treatment. Majority of the fistulas occurred after abdominal operations; many by general practitioners. After treatment for correction of fluid and electrolyte deficits, they were all tried on conservative therapy with enteral nutritional support as the main stay of management. Those, whose fistulas did not close, underwent surgical treatment. Total parenteral nutrition, octreotide, fibrin glue, and wound vacuum assisted closure (VAC) were not used for treating these patients. Spontaneous healing of fistulas occurred in 26 patients (31.7%), whereas 42 patients out of 50 (84%) healed after definitive operation. Fourteen patients (17%) in this study, died. Proper management of fluid and electrolyte imbalances, enteral nutritional support, control of sepsis and correctly timed surgical therapy, resulted in this good healing rate and acceptable mortality, without the use of parenteral nutrition, biologic fibrin glue injection or VAC. Suggestions are offered about steps that may help in eradicating some of these enterocutaneous fistulas.

Objective The goal of this study was to evaluate the first formal counseling program for obstetric fistula patients in Eritrea. Methods To evaluate the impact of the counseling program, clients were interviewed both before pre-operative counseling and again after post-operative counseling. A questionnaire was used in the interviews to assess women's knowledge about fistula, self-esteem, and their behavioral intentions for health maintenance and social reintegration following surgical repair. In addition, two focus groups were conducted with a total of 19 clients assessing their experiences with the surgical care and counseling. Results Data from the questionnaires revealed significant improvements in women's knowledge about fistula, self-esteem, and behavioral intentions following counseling. Focus group data also supported increased knowledge and self-esteem. Conclusion Evaluation of the short-term impact of an initial formal counseling program for fistula patients in sub-Saharan Africa affirmed the positive effects that such a program has for fistula patients, with increased knowledge about the causes of fistula, fistula prevention and enhanced self-esteem. Practical implications Culturally appropriate counseling can be incorporated into services for surgical repair of obstetric fistula in low-resource settings and has the potential to improve the physical and mental well-being of women undergoing fistula repair.

2017-01-01

Since 2007, ligation of the intersphincteric fistula tract (LIFT) for the management of anal fistula was all introduced with initial success and excitement. It remains controversial which surgical procedure is suitable for transsphincteric fistula, especially to complex anal fistula. This retrospective study was designed to evaluate the results in patients with recurrent anal fistula by LIFT. A retrospective study of 55 complex fistula patients who underwent LIFT procedure in a single medical center was analyzed. Patients and fistula characteristics, complications, and recurrences were reviewed. All 55 patients underwent the procedure with a median follow-up of 16 months. Median operative time was 44 (range 23-88) minutes. Of the 55 patients, 33 (60%) healed completely and did not require any further surgical treatment at end of follow-up. Twenty-two (40%) recurrences and six complications were observed. Compared with patients who had undergone more than two surgical procedures, LIFT was more suitable for patients who had undergone one to two surgical procedures, and significant difference was observed in number of operations before LIFT ( p = 0.002). Clinicians can consider the use of LIFT for the treatment of recurrent anal fistulas. A larger number of patients and prospective study are needed to be performed.

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

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

To summarize the social, economic, emotional, and psychological consequences incurred by women with obstetric fistula; present the results of a meta-analysis for 2 major consequences, divorce/separation and perinatal loss; and report on improvements in health and self-esteem and on the possibility of social reintegration following successful fistula repair. We conducted a review of the literature published between 1985 and 2005 on fistula in developing countries. We then performed a meta-analysis for 2 of the major consequences of having a fistula, divorce/separation and perinatal child loss. Studies suggest that surgical treatment usually closes the fistula and improves the physical and mental health of affected women. With additional social support and counseling, women may be able to successfully reintegrate socially following fistula repair.

Conflicts in wound classification of neonatal operations.

2009-06-01

This study sought to determine the reliability of wound classification guidelines when applied to neonatal operations. This study is a cross-sectional web-based survey of pediatric surgeons. From a random sample of 22 neonatal operations, participants classified each operation as "clean," "clean-contaminated," "contaminated," or "dirty or infected," and specified duration of perioperative antibiotics as "none," "single preoperative," "24 hours," or ">24 hours." Unweighted kappa score was calculated to estimate interrater reliability. Overall interrater reliability for wound classification was poor (kappa = 0.30). The following operations were classified as clean: pyloromyotomy, resection of sequestration, resection of sacrococcygeal teratoma, oophorectomy, and immediate repair of omphalocele; as clean-contaminated: Ladd procedure, bowel resection for midgut volvulus and meconium peritonitis, fistula ligation of tracheoesophageal fistula, primary esophageal anastomosis of esophageal atresia, thoracic lobectomy, staged closure of gastroschisis, delayed repair and primary closure of omphalocele, perineal anoplasty and diverting colostomy for imperforate anus, anal pull-through for Hirschsprung disease, and colostomy closure; and as dirty: perforated necrotizing enterocolitis. There is poor consensus on how neonatal operations are classified based on contamination. An improved classification system will provide more accurate risk assessment for development of surgical site infections and identify neonates who would benefit from antibiotic prophylaxis.

Participants for in-depth interviews and observation included women affected by obstetric fistula, their partners, parents, relatives, nurses and doctors. presentation of obstetric fistula information, particularly by Non-Governmental Organisations was not in a format that was readily understandable for many women and their families. Food and other basic requirements for daily living were not necessarily available in the fistula treatment centre. Travelling for care was costly and frequently not easily accessed from their communities. Fistula repair surgery was available at unpredictable times and only for a few days every one to two months. women perceived support from spouses/partner, family members, and other relatives but much of this is limited to tangible support. Perceptions of support were particularly focused on access to information and finances. the implementation of strategies to increase support for women living with obstetric fistula include improving access to fistula repair treatment, directing resources to create a dedicated specialist fistula centre located where most cases of OF occur and providing education to front-line workers. Strategies to prevent fistula as well as identify and support safe motherhood practices are needed for women affected by obstetric fistula. Copyright © 2016 Elsevier Ltd. All rights reserved.

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

PubMed Central

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

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

Social Experiences of Women with Obstetric Fistula Seeking Treatment in Kampala, Uganda.

Obstetric fistula is a preventable and treatable condition predominately affecting women in low-income countries. Understanding the social context of obstetric fistula may lead to improved prevention and treatment. This study investigated social experiences of women with obstetric fistula seeking treatment at Mulago Hospital in Kampala, Uganda. A descriptive study was conducted among women seeking treatment for obstetric fistula during a surgical camp in July 2011 using a structured questionnaire. Descriptive statistics were computed regarding sociodemographics, obstetric history, and social experience. Fifty-three women participated; 39 (73.58%) leaked urine only. Median age was 29 years (range: 17-58), and most were married or separated. About half (28, 47.9%) experienced a change in their relationship since acquiring obstetric fistula. More than half (27, 50.94%) acquired obstetric fistula during their first delivery, despite almost everyone (50, 94.3%) receiving antenatal care. The median years suffering from obstetric fistula was 1.25. Nearly every participant's social participation changed in at least one setting (51, 96.23%). Most women thought that a baby being too big or having kicked their bladder was the cause of obstetric fistula. Other participants thought health care providers caused the fistula (15, 32.61%; n = 46), with 8 specifying that the bladder was cut during the operation (cesarean section). Knowing someone with obstetric fistula was influential in pursuing treatment. The majority of participants planned to return to family (40, 78.43%; n = 51) and get pregnant after repair (35, 66.04%; n = 53). Study participants experienced substantial changes in their social lives as a result of obstetric fistula, and there were a variety of beliefs regarding the cause. The complex social context is an important component to understanding how to prevent and treat obstetric fistula. Further elucidation of these factors may bolster current efforts in prevention and holistic treatment. Copyright © 2017 Icahn School of Medicine at Mount Sinai. Published by Elsevier Inc.

Complex enterovisceral fistulas are internal fistulas joining a "diseased" organ to any intra-abdominal "victim" organ, with the exception of ileoileal fistulas. Few publications have addressed laparoscopic surgery for complex fistulas in Crohn's disease. The aim of this study was to evaluate the feasibility of such an approach. This study is a retrospective, case-match review. This study was conducted at a tertiary academic hospital. : All patients who underwent a laparoscopic ileocecal resection for complex enterovisceral fistulas between January 2004 and August 2011 were included. They were matched to a control group undergoing operation for nonfistulizing Crohn's disease according to age, sex, nutritional state, preoperative use of steroids, and type of resection performed. Matching was performed blind to the peri- and postoperative results of each patient. The 2 groups were compared in terms of operative time, conversion to open surgery, morbidity and mortality rates, and length of stay. Eleven patients presenting with 13 complex fistulas were included and matched with 22 controls. Group 1 contained 5 ileosigmoid fistulas (38%), 3 ileotransverse fistulas (23%), 3 ileovesical fistulas (23%), 1 colocolic fistula (8%), and 1 ileosalpingeal fistula (8%). There were no significant differences between the groups in terms of operative time (120 (range, 75-270) vs 120 (range, 50-160) minutes, p = 0.65), conversion to open surgery (9% vs 0%, p = 0.33), stoma creation (9% vs 14%, p = 1), global postoperative morbidity (18% vs 32%, p = 0.68), and major complications (Dindo III: 0% vs 9%, p = 0.54; Dindo IV: 0% vs 0%, p = 1), as well as in terms of length of stay (8 (range, 7-32) vs 9 (range, 5-17) days, p = 0.72). No patients died. This is a retrospective review with a small sample size. A laparoscopic approach for complex fistulas is feasible in Crohn's disease, with outcomes similar to those reported for nonfistulizing forms.

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

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

Orocutaneous fistula sometimes occurs in locallyadvanced unresectable or recurrent oral squamous cell carcinoma. The developed orocutaneous fistula results in constant leakage of saliva, ingested foods and liquids and decline in patients' quality of life(QOL). A 47-year-old Japanese man had received treatment for tongue carcinoma. At the routine follow-up, a cystic lesion in the right submandibular region was detected. Biopsyof the specimen of the cystic lesion revealed squamous cell carcinoma. After chemotherapy, an orocutaneous fistula between the right oropharyngeal and the right submandibular region developed and graduallyincreased. Although closure and dressing of the orocutaneous fistula with various materials was attempted, it was ultimatelyunsuccessful. Finally, application of a rubber film and silicone adhesive agent to the skin was successful for closure and dressing of the fistula. Orocutaneous fistula is one of major contributors to decline in patients' QOL. The sharing of information regarding effective methods or materials for closure and dressing of orocutaneous fistula is necessaryto maintain patients' QOL.

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

Introduction Gastrointestinal fistulas are serious complications and are associated with high morbidity and mortality rates. In majority of the patients, fistulas are treatable. However, the treatment is very complex and often multiple therapies are required. These highly beneficial treatment options which could shorten fistula closure time also result in considerable hospital cost savings. Aim This study was planned to study aetiology, clinical presentation, morbidity and mortality of enterocutaneous fistula and to evaluate the different surgical intervention techniques for closure of enterocutaneous fistula along with a comparative evaluation of different techniques for management of peristomal skin with special emphasis on aluminum paint, Karaya gum (Hollister) and Gum Acacia. Materials and Methods This prospective observational study was conducted in the Department of Surgery, M.L.N. Medical College, Allahabad and its associated hospital (S.R.N. Hospital, Allahabad) for a period of five years. Results Majority of enterocutaneous fistula were of small bowel and medium output fistulas (500-1000 ml/24hours). Most of the patients were treated with conservative treatment as compared to surgical intervention. Large bowel fistula has maximum spontaneous closure rate compare to small bowel and duodenum. Number of orifice whether single or multiple does not appear to play statistically significant role in spontaneous closure of fistula. Serum Albumin is a significantly important predictor of spontaneous fistula closure and mortality. Surgical management appeared to be the treatment of choice in distal bowel fistula. The application of karaya gum (Hollister kit), Gum Acacia and Aluminum Paint gave similar outcome. Conclusion Postoperative fistulas are the most common aetiology of enterocutaneous fistula and various factors do play role in management. Peristomal skin care done with Karaya Gum, Gum Acacia and Aluminum Paint has almost equal efficiency in management of skin excoriation. However, role of Gum Acacia was found to be good with inflamed, excoriated and ulcerative skin in comparison to Aluminum Paint and as efficacious as Karaya Gum but at much lower cost. PMID:26816943

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.

The use of open abdomen in the management of gastrointestinal fistula complicated with severe intra-abdominal infection is uncommon. This study was designed to evaluate outcomes of our staged approach for the infected open abdomen. Patients who had gastrointestinal fistula and underwent open abdomen treatment were retrospectively reviewed. Various materials such as polypropylene mesh and a modified sandwich package were used to achieve temporary abdominal closure followed by skin grafting when the granulation bed matured. A delayed definitive operation was performed for final abdominal closure without implant of prosthetic mesh. Between 1999 and 2009, 56 (68.3%) of 82 patients survived through this treatment. Among them, 42 patients achieved final abdominal closure. Spontaneous fistula closure occurred in 16 patients with secondary fistula recorded in six patients. Besides, wound complications occurred in 13 patients with two cases for pulmonary infection. Within a 12-month follow-up period after definitive closure, no additional fistula was recorded excluding planned ventral hernia repair. Open abdomen treatment was effective for gastrointestinal fistula complicated by severe intra-abdominal infection. A delayed and deliberate operative strategy aiming at fistula excision and fascial closure, with simultaneous abdominal wall reconstruction, was required for the infected open abdomen.

The occurrence of an enteric fistula in the middle of an open abdomen is called an enteroatmospheric fistula, which is the most challenging and feared complication for a surgeon to deal with. It is in fact not a true fistula because it neither has a fistula tract nor is covered by a well-vascularized tissue. The mortality of enteroatmospheric fistulae was as high as 70% in past decades but is currently approximately 40% due to advanced modern intensive care and improved surgical techniques. Management of patients with an open abdomen and an enteroatmospheric fistula is very challenging. Intensive care support of organs and systems is vital in order to manage the severely septic patient and the associated multiple organ failure syndrome. Many of the principles applied to classic enterocutaneous fistulae are used as well. Control of enteric spillage, attempts to seal the fistula, and techniques of peritoneal access for excision of the involved loop are reviewed in this report. Additionally, we describe our recent proposal of a lateral surgical approach via the circumference of the open abdomen in order to avoid the hostile and granulated surface of the abdominal trauma, which is adhered to the intraperitoneal organs.

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

Lang, Isabelle Joy; Fisch, Margit; Kluth, Luis Alex

2018-02-01

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

Vesicovaginal fistula secondary to obstructed labor continues to be an all-too-common occurrence in underdeveloped nations throughout Africa and Asia. Vesicovaginal fistula remains largely an overlooked problem in developing nations as it affects the most marginalized members of society: young, poor, illiterate women who live in remote areas. The formation of obstetric fistula is a result of complex interactions of social, biologic, and economic influences. The key underlying causes of fistula are the combination of a lack of functional emergency obstetric care, poverty, illiteracy, and low status of women. In order to prevent fistula, some strategies include creation of governmental policy aimed toward reducing maternal mortality/morbidity and increasing availability of skilled obstetric care, as well as attempts to increase awareness about its prevention and treatment among policymakers, service providers, and communities. Whereas prevention will require the widespread development of infrastructure within these developing countries, treatment of fistula is an act which can be done "in the now." Treatment and subsequent reintegration of fistula patients requires a team of specialists including surgeons, nurses, midwives, and social workers, which is largely unavailable in developing countries. However, there is increasing support for training of fistula surgeons through standardized programs as well as establishment of rehabilitation centers in many nations. The eradication of fistula is dependent upon building programs that target both prevention and treatment. © 2011 Mount Sinai School of Medicine.

Anal fistulas are common pathologies with a significant social impact; however, their treatment is often complex and the recurrence rate can be significant. Some surgical treatments for fistula are also associated with the risk of sphincter injury. In this technical note, we aim to evaluate the feasibility and efficacy of the Fat GRAFT technique (Fat Grafting in Anal Fistula Treatment) in the treatment of recurrent anal fistulas. All patients presenting with recurrent trans-sphincteric anal fistulas over an 18-month period were included. After abdominal fat harvesting and fat preparation, fat grafting was performed in the track and peripheral area of the fistula. The internal and external openings of the fistula were closed to maximally preserve the retention of the adipocyte graft in the fistula. Eleven patients underwent the Fat GRAFT procedure (seven men, four women). The average re-injected volume for each fistula was 21 ml (range 10-30 ml). The postoperative course was uneventful. At 6 months three patients developed recurrence (73% healed). There were no postoperative complications. The Fat GRAFT technique appears to be a promising technique with a low risk of anal incontinence, in contrast to other techniques. This method was effective in > 70% of patients in a single session.

The objective of this study is to gain insight into the nature of obstetric fistulae in Africa through patient perspectives. At l'Hôpital Saint Jean de Dieu in Tanguieta, Benin, 37 fistula patients underwent structured interviews about fistula cause, obstacles to medical care, prevention, and reintegration by 2 physicians via interpreters. The majority of participants (43%) thought their fistulae were a result of trauma from the operative delivery. Lack of financial resources (49%) was the most commonly reported obstacle to care, and prenatal care (38%) was most frequently reported as an intervention that may prevent obstetric fistulae. The majority (49%) of the participants requested no further reintegration assistance aside from surgery. Accessible emergency obstetric care is necessary to decrease the burden of obstetric fistulae in Africa. This may be accomplished through increased and improved health care facilities and education of providers and patients.

Subareolar abscess of the male breast is a rare condition, which can be complicated by a fistula from the areolar skin into a lactiferous duct. In 1951, Zuska et al first characterised this entity in women. Literature on mammillary fistulas in men is scarce and therefore standardisation of treatment does not exist. We present two cases of recurrent subareolar abscesses with draining fistulas. Both patients were successfully treated by complete excision of the lactiferous duct fistula, and continue to do well with no evidence of disease recurrence. When male patients present with a draining subareolar abscess, one should have a high index of suspicion for a mammillary fistula. Failure to identify and surgically excise the fistula may lead to recurrence of the abscess and prolonged morbidity. The most effective management of this uncommon entity includes complete excision of the lactiferous duct fistula. PMID:24706699

Rectovaginal fistula is a devastating condition providing more than 99% of patients for surgical treatment. We hypothesized that rectovaginal fistula may be healed by therapy with stable gastric pentadecapeptide BPC 157, in consistence with its initial clinical application and effect on external fistulas. BPC 157 (10μg/kg or 10ng/kg) was given perorally, in drinking water (0.16μg/ml or 0.16ng/ml, 12ml/rat/day) till sacrifice, or alternatively, intraperitoneally, first application at 30min after surgery, last at 24h before sacrifice. Controls simultaneously received an equivolume of saline (5.0ml/kg ip) or water only (12ml/rat/day). The assessment (i.e., rectal and vaginal defect, fistula leakage, defecation through the fistula, adhesions and intestinal obstruction as healing processes) was at day 1, 3, 5, 7, 10, 14 and 21. Regularly, rectovaginal fistulas exhibited poor healing, with both of the defects persisting, continuous fistula leakage, defecation through the fistula, advanced adhesion formation and intestinal obstruction. By contrast, BPC 157 given perorally or intraperitoneally, in μg- and ng-regimens rapidly improved the whole presentation, with both rectal and vaginal defects simultaneously ameliorated and eventually healed. The maximal instilled volume was continuously raised till the values of healthy rats were achieved, there were no signs of defecation through the fistula. A counteraction of advanced adhesion formation and intestinal obstruction was achieved. Microscopic improvement was along with macroscopic findings. BPC 157 effects appear to be suited to induce a full healing of rectovaginal fistulas in rats. Copyright © 2016 Elsevier Inc. All rights reserved.

Objective To report the associations of oro-nasal fistulae on the patient-centered outcomes oral health–related quality of life and self-reported speech outcomes in school aged-children. Design Prospective, nonrandomized multicenter design. Setting Six ACPA-accredited cleft centers. Participants Patients with cleft palate at the age of mixed dentition. Interventions None. Main Outcome Measures Prevalence of fistula and location of fistula (Pittsburgh Classification System). Patients were placed into one of three groups based on the following criteria: alveolar cleft present, no previous repair (Group 1); alveolar cleft present, previously repaired (Group 2); no congenital alveolar cleft (Group 3). Presence of fistula and subgroup classification were correlated to oral health–related quality of life (Child Oral Health Impact Profile [COHIP]) and perceived speech outcomes. Results The fistula rate was 5.52% (62 of 1198 patients). There was a significant difference in fistula rate between the three groups: Group 1 (11.15%), Group 2 (4.44%), Group 3 (1.90%). Patients with fistula had significantly lower COHIP scores (F1,1188 = 4.79; P = .03) and worse self-reported speech scores (F1,1197 = 4.27; P = .04). Group 1 patients with fistula had the lowest COHIP scores (F5,1188 = 4.78, P =.02) and the lowest speech scores (F5,1188 = 3.41, P = .003). Conclusions Presence of palatal fistulas was associated with lower oral health–related quality of life and perceived speech among youth with cleft. The poorest outcomes were reported among those with the highest fistula rates, including an unrepaired alveolar cleft. PMID:26437081

To investigate the pathology characteristics of congenital preauricular fistula with infection, in order to reduce the recurrence rate after surgery and improve operative technique. Twenty-five patients diagnosed as congenital preauricular fistula with infection were analyzed. There were 14 patients in infection history group, 9 in infective stage group, and 2 in recurrence group respectively. The whole piece of fistula and scar tissue was completely excised during operation. The specimens were observed by naked eye and serial tissue sections were analyzed. (1) Macroscopically, in infection history group, initial morphology can be maintained near the fistula orifice, but the distal tissue was dark red scar tissue. In infective stage group, the distal tissue of the specimens was granulation tissue and cicatricial tissue. The granulation tissue was crisp and bright red. In recurrence group, multicystic lesions with severe edema was observed, with a classical dumb-bell appearence. (2) Microscopically, in infection history group and recurrence group, we can see that the distal fistula tissue was discontinuous and was separated by scar tissue. In infective stage group, we can find neo-angiogenesis and infiltration of plasma cells, lymphocytes, neutrophil between interrupted fistula tissues. (3) All patients were followed up for 6-12 month, without recurrence. The fistula tissue of congenital preauricular fistula with infection was divided by the scar tissue, and they did not communicate with each other. Complete delineation of fistula is hardly achieved by methylene blue staining. Radical excision of the fistula and scar tissue may help to avoid leaving viable squamous epithelial remnants and reduce the recurrence rate.

Esophagopleural fistula (EPF) is a rare condition that is usually accompanied by severe infection and life-threatening morbidity. Here, we report the successful treatment of an EPF by closing an esophageal orifice using the over-the-scope-clip (OTSC) system without postprocedural complications. A 41-year-old man had serious thoracic and abdominal trauma due to a traffic accident. Computed tomography revealed findings suggestive of esophageal rupture due to Boerhaave syndrome. An emergent explorative operation was performed for primary repair with the insertion of a vacuum-assisted closure device. A postoperative upper gastrointestinal series revealed an EPF tract connecting the left pleural space and distal esophagus. We performed an endoscopic procedure using the "traumatic-type"OTSC to seal the EPF, and the esophageal orifice was completely healed 2 weeks postoperatively. The OTSC system might represent a safe and feasible modality for the treatment of EPF.

Extrahepatic portal obstruction is one of the causes of portal hypertension, in which well-developed hepatopetal pathways are commonly recognized. Herein an extremely rare case of extrahepatic portal obstruction without hepatopetal pathway, probably caused by arterioportal fistula, is reported. The patient was a normally matured 16-year-old girl admitted for further evaluation of jaundice, presenting with the clinical manifestations of the portal hypertension associated with hypersplenism and portosystemic venous shunt. Celiac angiography clearly demonstrated an intrahepatic arterial aneurysm fed by the right hepatic artery shunting to the superior mesenteric vein, and portography disclosed complete obstruction of the portal trunk with conspicuous hepatofugal pathway but no hepatopetal collateral veins. The exact mechanism of this phenomenon is not known and whether the extrahepatic portal obstruction was primary or secondary is still obscure. However, this is the first case report in the world literature describing extrahepatic portal obstruction with absence of hepatopetal pathway.

To prevent the pancreatic fistulas, we designed a technique termed "no naked pancreatic surface in the cavity of jejunum" on pancreaticojejunostomy. We adopted pancreatic exocrine secretions following the pancreatic duct by drainage; there was no naked pancreatic surface in the cavity of jejunum, and entail 2-3 cm sheath of the jejunum to the pancreatic stump. Only 3 (2.27%) cases developed pancreatic fistulas, 1 patient had a grade A leak, and 2 patients had grade B leakage. The overall morbidity was 25.76%. There was no dilatation of pancreatic duct or pancreatic enzyme deficiency shown during followed-up. The duration for accomplishing the anastomosis was 20 minutes averagely. The technique of no naked pancreatic surface in the cavity of jejunum can be routinely used in any case with pancreaticojejunostomy. It is a safe, simple, and effective technique that avoids the primary complication of anastomotic leakage.

The ideal closure technique of the pancreas after distal pancreatectomy is unknown. We postulated that standardised closure with a stapler device would prevent pancreatic fistula more effectively than would a hand-sewn closure of the remnant. This multicentre, randomised, controlled, parallel group-sequential superiority trial was done in 21 European hospitals. Patients with diseases of the pancreatic body and tail undergoing distal pancreatectomy were eligible and were randomly assigned by central randomisation before operation to either stapler or hand-sewn closure of the pancreatic remnant. Surgical performance was assessed with intraoperative photo documentation. The primary endpoint was the combination of pancreatic fistula and death until postoperative day 7. Patients and outcome assessors were masked to group assignment. Interim and final analysis were by intention to treat in all patients in whom a left resection was done. This trial is registered, ISRCTN18452029. Between Nov 16, 2006, and July 3, 2009, 450 patients were randomly assigned to treatment groups (221 stapler; 229 hand-sewn closure), of whom 352 patients (177 stapler, 175 hand-sewn closure) were analysed. Pancreatic fistula rate or mortality did not differ between stapler (56 [32%] of 177) and hand-sewn closure (49 [28%] of 175; OR 0·84, 95% CI 0·53–1·33; p=0·56). One patient died within the fi rst 7 days after surgery in the hand-sewn group; no deaths occurred in the stapler group. Serious adverse events did not differ between groups. Stapler closure did not reduce the rate of pancreatic fistula compared with hand-sewn closure for distal pancreatectomy. New strategies, including innovative surgical techniques, need to be identified to reduce this adverse outcome. German Federal Ministry of Education and Research.

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.

Intracranial pial arteriovenous fistulas, also known as nongalenic fistulas, are rare vascular malformations affecting predominantly the pediatric population. Hydrocephalus is an unusual presentation in which the exact pathophysiology is not fully understood. The aim of treatment in these cases is occlusion of the fistula prior to considering ventricular shunting. Here, the authors describe the hydrodynamic considerations of the paravascular pathway and the resolution of hydrocephalus with endovascular treatment of the fistula.

A 67-year-old woman who had undergone rhytidectomy 5 years before her presentation experienced increasing pulsatile tinnitus on the left side that had begun 2 years earlier. Angiography revealed a direct arteriovenous fistula between the superficial temporal artery and superficial temporal vein in front of her left ear. There was a scar from the earlier cosmetic surgery at the site. The fistula was embolized with N-butyl cyanoacrylate, and her tinnitus disappeared. We posit that the fistula was a complication of rhytidectomy and that a small arteriovenous fistula formed at the time of surgery and enlarged over time. This case indicates that arteriovenous fistulae can occur as a delayed complication of cosmetic surgery.

To analyze the outcomes of arteriovenous fistulae (AVFs) creation in octogenarians. A retrospective study of 47 AVFs created in patients aged 80 years and above from 2008 to 2014. Patient and AVF characteristics and outcomes were evaluated. Predictors of patency were analyzed with multivariate analysis and Kaplan-Meier patency, and survival analysis was performed. Forty-seven of 1,259 AVFs created were for octogenarians (4%). Mean age was 83 years old (range: 80-91 years), with 27 male (57%) and 35 with tunneled dialysis catheters in situ (75%). There were a total of 15 (32%) radiocephalic AVFs, 30 (64%) brachial-cephalic AVFs, and 2 (4%) brachial-basilic transposition AVFs. At 12 months, assisted primary patency rate was 28% (13 patients) while primary failure rate was 72% (34 patients). Subset analysis showed brachial-cephalic AVFs to have the highest assisted primary patency rate at 33%. Within 24 months, tunneled dialysis catheter-related sepsis rate was 31% (11 patients). Multivariate analysis did not reveal any factor to be statistically significant in predicting AVF patency. Kaplan-Meier survival curve showed a 50% survival rate at 63 months after AVF creation. In view of high AVF primary failure rate and relatively low tunneled dialysis catheter bacteremia rate, long-term tunneled dialysis catheters as the main form of hemodialysis renal access may be a viable option. However, with 50% of end-stage renal failure patients surviving up to 63 months after AVF creation, the risks and benefits of long-term tunneled dialysis catheters must be balanced against those of AVF creation.

Outcomes of mechanical stapling for postlaryngectomy open pharyngotomy closure.

PubMed

Paddle, Paul; Husain, Inna; McHugh, Lauren; Franco, Ramon

2017-03-01

A total laryngectomy (TL) is performed as a primary or salvage therapy for laryngeal carcinoma. Pharyngotomy closure after TL is typically performed using manual sutures. Automatic stapling devices are routinely used in thoracoabdominal surgery, but have not been widely accepted for use in pharyngotomy closure. Previously described closed stapling techniques of pharyngeal closure do not allow direct evaluation of surgical margins and are limited to endolaryngeal disease. We describe an open technique for pharyngotomy closure using a mechanical stapling device. Retrospective review. A review was conducted of 16 total laryngectomies performed from May 2008 to August 2015 utilizing an Ethicon Endopath ETS Compact-Flex 45 stapler. Sixteen patients (15 male, one female), mean age 69 years, received open TL (14 salvage, two primary) with endostapler pharyngeal closure and primary tracheoesophageal puncture (TEP). Surgical time averaged 218 minutes. Median time to swallowing was 4 days (range, 2-240 days) and mean hospital stay 6 days (range, 3-10 days). Fistula incidence was 31% (5/16) overall and 36% (5/14) in the postradiation patients. Mechanical stapling is a simple method for postlaryngectomy open pharyngotomy closure. This technique allows evaluation of margins, easy primary TEP, and the opportunity for early swallowing and shorter hospital stays. In addition, it can be performed for closure of salvage laryngectomies with rates of fistula formation similar to that found in the literature using suture closure techniques. Future studies are necessary to compare oncological results and surgical complications between the open and closed stapling techniques and to traditional suture closure. 4 Laryngoscope, 127:605-610, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

A 69-year-old male had catheter-based ablation for atrial fibrillation. He was admitted with high fever and had neurological disorder; he was diagnosed with atrioesophageal fistula by CT scan. Intraoperative findings showed that the fistula existed adjacent to the left lower pulmonary vein with a vegetation. The esophageal fistula was repaired, and the left atrial fistula was closed. A nasogastric tube tip was placed in the esophagus for decompression and advanced into the stomach for nutritional support. After vomiting, the patient showed loss of consciousness and left hemiplegia. CT scan revealed a micro-air embolism to the brain. The nasogastric tube tip was pulled back into the esophagus. Gastrointestinal fiberscopy showed a pinhole at the fistula, and a percutaneous endoscopic gastrostomy was made. After conservative treatment, the esophageal fistula was closed and mediastinitis was improved. He was discharged with a little neurological deficit.

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.

Esophageal fistula is a serious and common complication of radiotherapy for esophageal cancer. Therefore, early diagnosis and treatment is necessary. Because of side effect of barium esophagography, it cannot be used to screening esophageal fistula during radiotherapy. Meglumine diatrizoate is an ionic contrast agent, its adverse reactions were rarely seen when it was used in the body cavity. The purpose of this trial is identified the sensitivity and specificity of oral meglumine diatrizoate in an esophagogram for screening esophageal fistula during radiotherapy. This trial was a prospective, multicenter, diagnostic clinical trial. A total of 105 patients with esophageal cancer will swallowed meglumine diatrizoate and underwent a radiographic examination weekly during radiotherapy, medical personnel observed the esophageal lesions to determine whether an esophageal fistula formed. If an esophageal fistula was observed, esophagofiberoscopy and/or computer tomography was used to further confirm the diagnosis. And the sensitivity and specificity of meglumine diatrizoate should be calculated for screening esophageal fistula during radiotherapy. To our knowledge, this study protocol is the first to identify the sensitivity and specificity of oral meglumine diatrizoate in an esophagogram for screening esophageal fistula during radiotherapy. If oral meglumine diatrizoate can be used to screening esophageal fistula, more patients will benefit from early detection and treatment.

To derive a comprehensive system that allows a single score to define relative fistula severity. The present observational study included women with urogenital fistula treated at the Panzi Hospital, Democratic Republic of Congo, or its outreach clinics across the Democratic Republic of Congo between September 1, 2013, and December 31, 2014. Fistula severity was assessed by Goh and Waaldijk classifications and surgical success was ascertained. Logistic regression was used to select fistula characteristics predictive of surgical failure, and to preliminarily verify the newly derived Panzi score. Overall, 837 women were included in the analysis. Goh or Waaldijk fistula descriptors associated with a higher probability of poor surgical outcomes in the unadjusted bivariate analysis were circumferential defect (P=0.007), proximity to the external urethral orifice (P=0.001), and size (P=0.001). These fistula characteristics were used to construct the Panzi score, which varied from 3 (most severe) to 0 (minor fistula). For each increase above 0, the odds of surgical failure increase by a factor of 1.65 (P<0.001). The Panzi score of urogenital fistula provided a data-driven, simple, comprehensive, and parsimonious score. It could be used to report group data, to provide continuous level data for use in higher order statistics, and to resolve issues such as the cut-off point for referring women to hospital in accordance with fistula complexity.

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

OBJECTIVE: This study determined whether there are any laboratory or other features that will enable prediction of spontaneous closure in patients with gastrointestinal cutaneous fistulas. SUMMARY BACKGROUND DATA: Although the anatomic criteria for spontaneous closure of gastrointestinal cutaneous fistulas have been presented by several authors, less than 50% of such fistulas tend to close, even in the most recent series. METHODS: A group of patients with gastrointestinal cutaneous fistulas with anatomical features favorable to study were investigated with respect to a series of parameters including the usual demographic parameters, plus fistula output, number of blood transfusions, presence of sepsis, as well as metabolic parameters including serum transferrin, retinol-binding protein, thyroxin-binding prealbumin, and serum albumin. RESULTS: Of 79 patients with 116 fistulas, 16 (20.3%) died. Causes of death were uncontrolled sepsis in eight patients and cancer in five patients. Postoperative fistulas constituted 80% of the group. The presence of local sepsis, systemic sepsis, remote sepsis (such as pneumonia or line sepsis), the number of fistulas, fistula output, and the number of blood transfusions were not predictive of spontaneous closure, whereas serum transferrin was predictive of spontaneous closure. Serum transferrin, retinol-binding protein, and thyroxin-binding prealbumin were predictive of mortality. CONCLUSIONS: Serum transferrin does not appear to be an entirely independent variable, but seems to identify those patients with significant remote sepsis, systemic sepsis, and neoplasia in whom these processes are clinically significant. The results, if confirmed, and provided that nutritional needs are met, suggest that short-turnover proteins, particularly serum transferrin, might be useful in predicting which patients with gastrointestinal cutaneous fistulas should undergo surgery despite anatomic criteria favorable for spontaneous closure.

Community-based screening for obstetric fistula in Nigeria: a novel approach

PubMed Central

2014-01-01

Background Obstetric fistula continues to have devastating effects on the physical, social, and economic lives of thousands of women in many low-resource settings. Governments require credible estimates of the backlog of existing cases requiring care to effectively plan for the treatment of fistula cases. Our study aims to quantify the backlog of obstetric fistula cases within two states via community-based screenings and to assess the questions in the Demographic Health Survey (DHS) fistula module. Methods The screening sites, all lower level health facilities, were selected based on their geographic coverage, prior relationships with the communities and availability of fistula surgery facilities in the state. This cross-sectional study included women who presented for fistula screenings at study facilities based on their perceived fistula-like symptoms. Research assistants administered the pre-screening questionnaire. Nurse-midwives then conducted a medical exam. Univariate and bivariate analyses are presented. Results A total of 268 women attended the screenings. Based on the pre-screening interview, the backlog of fistula cases reported was 75 (28% of women screened). The backlog identified after the medical exam was 26 fistula cases (29.5% of women screened) in Kebbi State sites and 12 cases in Cross River State sites (6.7%). Verification assessment showed that the DHS questionnaire had 92% sensitivity, 83% specificity with 47% positive predictive value and 98% negative predictive value for identifying women afflicted by fistula among women who came for the screenings. Conclusions This methodology, involving effective, locally appropriate messaging and community outreach followed up with medical examination by nurse-midwives at lower level facilities, is challenging, but represents a promising approach to identify the backlog of women needing surgery and to link them with surgical facilities.

Obstetric fistula is a worldwide problem that affects women and girls mostly in Sub Saharan Africa. It is a devastating medical condition consisting of an abnormal opening between the vagina and the bladder or rectum, resulting from unrelieved obstructed labour. Obstetric fistula has devastating social, economic and psychological effect on the health and wellbeing of the women living with it. This study aimed at exploring social-cultural experiences of women living with obstetric fistula in rural Tanzania. Women living with obstetric fistula were identified from the fistula ward at CCBRT hospital. Sixteen individual semi structured interviews and two (2) focus group discussions were conducted among consenting women. Interviews were transcribed verbatim and transcripts analysed independently by two researchers using a thematic analysis approach. Themes related to the experiences of living with obstetric fistula were identified. Four themes illustrating the socio-cultural experiences of women living with obstetric fistula emerged from the analysis of women experiences of living with incontinence and odour. These were keeping clean and neat, earning an income, maintaining marriage, and keeping association. Women experiences of living with fistula were largely influenced by perceptions of people around them basing on their cultural understanding of a woman. Living with fistula reveals women's day-to-day experiences of social discrimination and loss of control due to incontinence and odour. They cannot work and contribute to the family income, cannot satisfy their husband's sexual needs and or bear children, and cannot interact with members of the community in social activities. Women experience of living with fistula was influenced by perceptions of people around them. In the eyes of these people, women who leak urine were of less value since they were not capable of carrying out ascribed social roles.

Revisiting an ancient treatment for transphincteric fistula-in-ano ‘There is nothing new under the sun’ Ecclesiastes 1v9

Objective The history of treatments for fistula-in-ano can be traced back to ancient times. Current treatment of transphincteric fistulae is controversial, with many options available. We reviewed the history of treatment using cutting setons and present our series of transphincteric fistulae in the light of the series in the literature. Design Literature review and case series. Setting Hospital based coloproctology service Participants 140 consecutive patients presenting with fistula-in-ano were included. Main Outcome Measures The literature pertaining to treatment of transphincteric fistula was reviewed, along with the outcome of various treatment methods for this condition. Data were collected for 140 consecutive patients presenting with fistula- in-ano were assessed for fistula healing, recurrence and complications. Results A total of 140 consecutive patients with fistula-in-ano were identified, of which 111 were cryptoglandular (79.3%). Eighty-one of these 111 were transphincteric (73.0%). At a median follow-up of 35 months (range, 2–83 months), 70 transphincteric fistulae had healed (86.4%), 10 were still undergoing treatment (12.3%) and one patient was lost to follow-up prior to treatment (1.2%). Two patients in this group required a stoma (2.5%), six patients developed recurrence (7.4%); three ‘true’ recurrences (3.7%). One (1.2%) developed a chronic fissure. There were no reported cases of incontinence. Conclusions The management of transphincteric fistula-in-ano is complex and controversial, for which no clear surgical procedure has gained acceptance as the gold standard. This study demonstrates that transphincteric fistulae can be successfully treated using cutting setons. A high healing rate (86.4%), low recurrence rate (7.4%) and a low complication rate (3.7%) are shown, which compares favourably with published rates over a long follow-up. PMID:26152674

Obstetric fistula classic symptoms of faecal and urinary incontinence cause women to live with social stigma, isolation, psychological trauma and lose their source of livelihoods. There is a paucity of studies on the health seeking behaviour trajectories of women with fistula illness although women live with the illness for decades before surgery. We set out to establish the complete picture of women's health seeking behaviour using qualitative research. We sought to answer the question: what patterns of health seeking do women with obstetric fistula display in their quest for healing? We used grounded theory methodology to analyse data from narratives of women during inpatient stay after fistula surgery in 3 hospitals in Kenya. Emergent themes contributed to generation of substantive theory and a conceptual framework on the health seeking behaviour of fistula patients. We recruited 121 participants aged 17 to 62 years whose treatment pathways are presented. Participants delayed health seeking, living with fistula illness after their first encounter with unresponsive hospitals. The health seeking trajectory is characterized by long episodes of staying home with illness for decades and consulting multiple actors. Staying with fistula illness entailed health seeking through seven key actions of staying home, trying home remedies, consulting with private health care providers, Non-Governmental organisations, prayer, traditional medicine and formal hospitals and clinics. Long treatment trajectories at hospital resulted from multiple hospital visits and surgeries. Seeking treatment at hospital is the most popular step for most women after recognizing fistula symptoms. We conclude that the formal health system is not responsive to women's needs during fistula illness. Women suffer an illness with a chronic trajectory and seek alternative forms of care that are not ideally placed to treat fistula illness. The results suggest that a robust health system be provided with expertise and facilities to treat obstetric fistula to shorten women's treatment pathways.

Obstetric fistula is a childbirth injury caused by prolonged obstructed labor that results in destruction of the tissue wall between the vagina and bladder. Although obstetric fistula is directly caused by prolonged obstructed labor, many other factors indirectly increase fistula risk. Some research suggests that many women in rural Malawi have limited autonomy and decision-making power in their households. We hypothesize that women's limited autonomy may play a role in reinforcing childbirth practices that increase the risk of obstetric fistula in this setting by hindering access to emergency care and further prolonging obstructed labor. A medical student at Baylor College of Medicine partnered with a Malawian research assistant in July 2015 to conduct in-depth qualitative interviews in Chichewa with 25 women living within the McGuire Wellness Centre's catchment area (rural Central Lilongwe District) who had received obstetric fistula repair surgery. This study assessed whether women's limited autonomy in rural Malawi reinforces childbearing practices that increase risk of obstetric fistula. We considered four dimensions of autonomy: sexual and reproductive decision-making, decision-making related to healthcare utilization, freedom of movement, and discretion over earned income. We found that participants had limited autonomy in these domains. For example, many women felt pressured by their husbands, families, and communities to become pregnant within three months of marriage; women often needed to seek permission from their husbands before leaving their homes to visit the clinic; and women were frequently prevented from delivering at the hospital by older women in the community. Many of the obstetric fistula patients in our sample had limited autonomy in several or all of the aforementioned domains, and their limited autonomy often led both directly and indirectly to an increased risk of prolonged labor and fistula. Reducing the prevalence of fistula in Malawi requires a broad understanding of the causes of fistula, so we recommend that the relationship between women's autonomy and fistula risk undergo further investigation.

Enterocutaneous fistula: are treatments improving?

We studied the etiology, treatment, and outcome of enterocutaneous fistulas in 106 patients to evaluate our current practice and the impact of newer therapies-octreotide, wound vacuum-assisted closure (VAC), and fibrin glue-on clinical outcomes. Review of the literature and our own 1990 study indicate a mortality rate of 5% to 20% for enterocutaneous fistula, and a healing rate of 75% to 85% after definitive surgery. We reviewed all cases of gastrointestinal-cutaneous fistula from 1997 to 2005 at 2 large teaching hospitals. We identified 106 patients with enterocutaneous fistula; patients with irritable bowel disease and anorectal fistulas were excluded. The origin of the fistula was the small bowel in 67 patients, colon in 26, stomach in 8, and duodenum in 5. The etiology of the fistula was previous operation in 81 patients, trauma in 15, hernia mesh erosion in 6, diverticulitis in 2, and radiation in 2. Of the 106 patients in the study, 31 had a high output fistula (greater than 200 mL/day), 44 had a low output fistula, and, in 31 patients, the fistula output was low but there was no record of volume. Initial treatment was nonoperative except for patients with an abscess who needed urgent drainage. In 24 patients, the effect of octreotide was monitored: in 8 patients, fistula output declined; in 16 patients, octreotide was of no benefit. Fibrin glue was used in 8 patients and was of benefit to 1. The wound VAC was used in 13 patients: 12 patients still required operative repair of the fistula, whereas the fistula was healed in 1 patient. The main benefit of the VAC system was improved wound care in all patients before definitive surgery. Total parenteral nutrition was used in most patients to provide nutritional support. Operative repair was performed in 77 patients and was successful in 69 (89%), failing in 6 patients with persistent cancer or infection. Nonoperative treatment was used in 29 patients and resulted in healing in 60%. Of 106 patients, 7 (7%) died of fistula complications. The cause of death was persistence or recurrence of cancer in 4 patients and persistent sepsis in 3. Enterocutaneous fistula continues to be a serious surgical problem. The wound VAC and fibrin glue had anecdotal successes (n = 2), and one-third of patients responded to octreotide. We believe that octreotide should be tried in most patients and that the wound VAC has a role in selected patients. Although 7% overall mortality is lower than in previous studies, the number managed without operation (27%) remains the same. In addition to early control of sepsis, nutritional support, and wound care, a well-timed operation was the most effective treatment.

We report a case of a 57-year-old man with typical angina due to a coronary artery-to-pulmonary artery fistula, which was evident on transthoracic and transesophageal echocardiography with color Doppler flow mapping. The diagnosis was confirmed by coronary angiography. The patient underwent surgical ligation of the fistula. However, repeated transesophageal echocardiography and coronary angiography revealed persistence of the fistula with significant left-to-right shunt. The orifice of the fistula was then obliterated by stent-graft implantation, which was proven successful by angiography and echocardiography. PMID:24570733

Enterocutaneous fistulas occur most commonly following surgery. A minority of them is caused by a myriad of other etiologies including infection, malignancy, and radiation. While some fistulas may close spontaneously, most patients will eventually need surgery to resolve this pathology. Successful treatment entails adoption of various methods of treatment aimed at control of sepsis, protection of surrounding skin and soft tissue, control of fistula output, and maintenance of nutrition, with eventual spontaneous or surgical closure of the fistula. The aim of this article is to review the various treatment options in their appropriate context. PMID:28825016

Severe acute necrotising pancreatitis is associated with numerous local and systemic complications. Abdominal compartment syndrome requiring urgent decompressive laparotomy is a potential complication of this disease process and is associated with increased morbidity and mortality. We describe the case of a pancreaticoatmospheric fistula following decompressive laparotomy in a patient with severe acute necrotising pancreatitis. While this fistula was managed successfully using the current standard of care for pancreatic fistulas, the wound care for in this patient with drainage of the fistula through an open abdomen, is a significant challenge.

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

Obstetric fistula: what about gender power?

2012-01-01

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.

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

Fistula rates after salvage laryngectomy: comparing pectoralis myofascial and myocutaneous flaps.

Salvage laryngectomy after failed organ preservation often has a high complication rate, pharyngocutaneous fistulas being the most common. These fistulas increase morbidity, prolong hospitalization, and potentially delay adjuvant treatment. Fistula rates in the literature range from 3% to 65%. Use of the pectoralis flap to prevent fistula formation has been adopted as a common practice at our institution. A review of our experience using the overlay myofascial showed a higher than desired complication rate. The aim of this study is to assess whether the use of integrated myocutaneous flap results in a lower fistula rate. A retrospective review of 30 patients followed by a pilot study of 10 patients. All underwent salvage laryngectomy after failed organ preservation. The operation notes of 40 laryngectomy patients were analyzed. The patient/tumor characteristics, pretreatment, neck dissection, flap type, and fistula rate were documented. The patient sample was 25% female. All patients received prior radiotherapy, but only 37.5% received prior chemoradiation. Neck dissections were performed in 80% of these patients, 76% of the myocutaneous group, and 84% of the myofascial group. Advanced tumor stage was found in 42% of the myofascial group and 52% of the myocutaneous group. Five of the 19 myofascial patients developed a fistula, whereas seven of the 21 myocutaneous patients developed a fistula. The use of the pectoralis myocutaneous flap (PMCF) in this pilot series did not show a lower rate of fistula; other alternatives should be pursued to decrease this complication. 4. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

We tested the null hypothesis that there were no differences between patients with obstetric fistula and parous controls without fistula. A unmatched case-control study was carried out comparing 75 women with a history of obstetric fistula with 150 parous controls with no history of fistula. Height and weight were measured for each participant, along with basic socio-demographic and obstetric information. Descriptive statistics were calculated and differences between the groups were analyzed using Student's t test, Mann-Whitney U test where appropriate, and Chi-squared or Fisher's exact test, along with backward stepwise logistic regression analyses to detect predictors of obstetric fistula. Associations with a p value <0.05 were considered significant. Patients with fistulas married earlier and delivered their first pregnancies earlier than controls. They had significantly less education, a higher prevalence of divorce/separation, and lived in more impoverished circumstances than controls. Fistula patients had worse reproductive histories, with greater numbers of stillbirths/abortions and higher rates of assisted vaginal delivery and cesarean section. The final logistic regression model found four significant risk factors for developing an obstetric fistula: age at marriage (OR 1.23), history of assisted vaginal delivery (OR 3.44), lack of adequate antenatal care (OR 4.43), and a labor lasting longer than 1 day (OR 14.84). Our data indicate that obstetric fistula results from the lack of access to effective obstetrical services when labor is prolonged. Rural poverty and lack of adequate transportation infrastructure are probably important co-factors in inhibiting access to needed care.

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

Fistuloclysis: An Interprofessional Approach to Nourishing the Fistula Patient.

Enteric fistulas can be classified as enterocutaneous and/or enteroatmospheric. Both are devastating complications of bowel disease, abdominal surgery, and/or open abdomen. Enteric fistulas are associated with a mortality rate varying from 1% to 33%; the main cause of death is sepsis. Coordinated and skillful efforts of an interprofessional team are required in customizing successful treatment regimens appropriate to each patient's unique clinical scenario. A 65-year-old white woman experienced an enteroatmospheric fistula patient after ventral hernia repair. Care of this patient was based on the complementary relationship between professionals from 2 disciplines: the wound and ostomy continence nurse (WOC nurse) and the nutrition support registered dietitian/nutritionist. Working together, they developed a comprehensive wound, ostomy, and nutritional plan. Initially, the patient received parenteral nutrition exclusively. After the fistula tract was clearly defined, a feeding tube was placed into the distal limb of the fistula, and she received nourishment via a fistuloclysis (ie, enteral feedings administered via the fistula). A special wound management system was created to contain fistula output while allowing feeding through the distal limb of the fistula. Enterocutaneous and enteroatmospheric fistulas originating from the small bowel present a management challenge to the entire healthcare team. WOC nurses are often called upon to meet the challenge of maintaining skin health while promoting dignity and function. Nutrition support via registered dietitian/nutritionists play a critical role in managing the nutrition regimen for these patients. In this case, the use of fistuloclysis met the patient's nutritional needs while avoiding the risks associated with parenteral nutrition.

Delays in arteriovenous fistula maturation can cause care delays and increased costs. Increased distention pressure and intermittent wall shear stress may dilate veins based on prior research. Early use of non-invasive devices may help assist clinical arteriovenous fistula dilation. This was an Institutional Review Board approved study. After arteriovenous fistula creation, a novel, intermittent pneumatic compression device (Fist Assist ® ) was applied 15 cm proximal to arteriovenous fistula enabling 60 mmHg of cyclic compression for 6 h daily for 30 days. Among the patients who completed 1 month follow-up, 30 (n = 30) arteriovenous fistula patients were in the study arm to test vein dilation with Fist Assist. Controls (n = 16) used a sham device. Vein size was measured and recorded at baseline and after 30 days by duplex measurement. Clinical results (percentage increase) were recorded and tested for significance. No patients experienced thrombosis or adverse effects. Patient compliance and satisfaction was high. After 1 month, the mean percentage increase in vein diameter in the Fist Assist treatment group was significantly larger (p = 0.026) than controls in the first 5 mm segment of the fistula after the anastomosis. All fistulas treated with Fist Assist are still functional with no reported thrombosis or extravasations. Early application of an intermittent pneumatic compression device may assist in arteriovenous fistula dilation and are safe. Non-invasive devices like Fist Assist may have clinical utility to help fistulae development and decrease costs as they may eventually assist maturation.

Closing the internal opening by a clip ovesco has been recently proposed for healing the fistula tract, but, to date, data on benefit are poorly analyzed. The aim was to report a preliminary multicenter experience. Retrospective study was undertaken in six different French centers: surgical procedure, immediate complications, and follow-up have been collected. Nineteen clips were inserted in 17 patients (M/F, 4/13; median age, 42 years [29-54]) who had an anal fistula: 12 (71%) high fistulas (including 4 rectovaginal fistulas), 5 (29%) lower fistulas (with 3 rectovaginal fistulas), and 6 (35%) Crohn's fistulas. Out of 17 patients, 15 had a seton drainage beforehand. The procedure was easy in 8 (47%) patients and the median operative time was 27.5 min (20-36.5). Postoperative period was painful for 11 (65%) patients. A clip migration was noted in 11 patients (65%) after a median follow-up of 10 days (5.5-49.8). Eleven patients (65%) who failed had reoperation including 10 new drainages within the first month (0.5-5). After a mean follow-up of 4 months (2-7),, closing the tract was observed in 2 patients (12%) following the first insertion of the clip and in another one after a second insertion. Treatment of anal fistula by placing a clip on the internal opening is disappointing and deleterious for some patients. A better assessment before dissemination is recommended.

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.

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

A newborn male weighing 3,650 g was born without an anal opening and a perineal fistula. However, an invertography showed rectal gas below the ischium. At the age of 1 day, the patient underwent colostomy. Based on colonourethrography that revealed a fistula between the rectum and the spongy urethra, the patient was diagnosed with an anopenile urethral fistula (APUF). At the age of 7 months, the patient underwent anterior sagittal anorectoplasty (ASARP). The sphincter muscles were divided at the midline. After ligating the fistula, the rectum was pulled through to the anal dimple. At the age of 11 months, a colostomy closure was performed. Consequently, the fistula in the corpus spongiosum penis was not removed. It has been 14 years since the operation was performed, and the patient has had no problems with regard to urination and defecation. According to the embryological studies of the anorectum, APUF could occur due to the following reasons: incomplete descent of the urorectal septum, failed disappearance of the dorsal cloacal membrane, and excessive elongation of the urorectal septum in the phallus. The ASARP provides a superior operative field to identify the fistula and the sphincter muscles. Complete removal of the fistula in the corpus spongiosum penis is unnecessary.

Managing complex, high-output, enterocutaneous fistulas: a case study.

Gastrointestinal (GI) fistulas are an uncommon but serious complication. Following diagnosis, management strategies may have to be adapted frequently to address changes in fistula output, surrounding skin or wound condition, overall patient clinical and nutritional status, mobility level, and body contours. Following a motor vehicle accident, a 49-year-old man with a body mass index of 36.8 and a history of multiple previous surgeries, including gastric bypass, experienced excessive output from a fistula within a large open abdominal wound measuring 45 cm x 40 cm x 5 cm. Abdominal creases and the need to protect a split-thickness skin graft of the wound surrounding his fistula complicated wound management. During his prolonged 4-month hospital stay, the patient underwent several surgical procedures, repeated wound debridement, and various nutritional support interventions; a wide variety of wound and fistula management systems were utilized. One year after the initial trauma, the fistula was surgically closed. One week later, the patient died from a cardiac event. This case study confirms that GI fistulas increase costs of care and hospital length of stay and require the experience and expertise of a wide array of patient support staff members and clinicians.

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

Vacuum effects over the closing of enterocutaneous fistulae: a mathematical modeling approach.

PubMed

Cattoni, D I; Chara, O

Enterocutaneous fistulae are pathological communications between the intestinal lumen and the abdominal skin. Under surgery the mortality of this pathology is very high, therefore a vacuum applying system has been carried previously on attempting to close these fistulae. The objective of this article is the understanding of how these treatments might work through deterministic mathematical modelling. Four models are here proposed based on several assumptions involving: the conservation of the flow in the fistula, a low enough Reynolds number justifying a laminar flow, the use of Poiseuille law to model the movement of the fistulous liquid, as well as phenomenological equations including the fistula tissue and intermediate chamber compressibility. Interestingly, the four models show fistulae closing behaviour during experimental time (t<60 sec). To compare the models, both, simulations and pressure measurements, carried out on the vacuum connected to the patients, are performed. Time course of pressure are then simulated (from each model) and fitted to the experimental data. The model which best describes actual measurements shows exponential pumping flux kinetics. Applying this model, numerical relationship between the fistula compressibility and closure time is presented. The models here developed would contribute to clarify the treatment mechanism and, eventually, improve the fistulae treatment.

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

Delayed Diagnosis of Vesicouterine Fistula After Treatment for Mixed Urinary Incontinence: Menstrual Cup Management and Diagnosis.

Goldberg, Leah; Elsamra, Sammy; Hutchinson-Colas, Juana; Segal, Saya

2016-01-01

A vesicouterine fistula is a rare form of urogenital fistula, yet there is increasing prevalence in the United States because of the rising rate of cesarean deliveries. Vesicouterine fistulas have various presentations including menouria, hematuria, or urinary incontinence. A 39-year-old multiparous woman presented with urine leakage after her third cesarean delivery. She had been treated for mixed urinary incontinence with overactive bladder medications and a midurethral sling with continued complaints of urine leakage. The patient noticed her symptoms of urine leakage improved during menses when she used a menstrual cup. After confirmation of vesicouterine fistula, the patient underwent robotic-assisted surgery and her symptoms of insensible urine leakage resolved. When evaluating women with urinary incontinence and a history of cesarean deliveries, use of menstrual cup may aid in the diagnosis of vesicouterine fistula. Robotic-assisted laparoscopic repair with tissue interposition flap is an efficacious minimally invasive method for treatment of vesicouterine fistula.

The efficacy of a crude hydro-alcoholic extract of Cassia fistula (golden shower tree) fruit to protect the kidney against bromobenzene-induced toxicity was studied. Negative control mice received normal saline; positive control mice were given 460 mg/kg of bromobenzene; Cassia fistula treated mice received 200, 400, 600 and 800 mg/kg of Cassia fistula fruit extract followed by 460 mg/kg bromobenzene (daily by oral gavage for 10 days). On the 11th day, the mice were sacrificed, blood samples were obtained to assess blood urea nitrogen (BUN) and creatinine levels, and kidneys were removed for histological examination. We found that bromobenzene induced significant nephrotoxicity reflected by an increase in levels of BUN and creatinine that was dose dependently prevented by the Cassia fistula fruit extract. The nephroprotective effect of the Cassia fistula fruit extract was confirmed by the histological examination of the kidneys. To the best of our knowledge, this is the first study to demonstrate the protective effect of Cassia fistula in nephrotoxicity.

To assess the effectiveness of buccal mucosa patch graft in the treatment of recurrent large urethrocutaneous fistula after hypospadias repair. A free graft of buccal mucosa was used for closure in 7 boys (mean age 4.8 years) with large (>4 mm) urethocutaneous fistula. Four fistulas were in the midshaft, 2 of them penoscrotal and 1 coronal type. All patients had undergone at least two previous unsuccessful fistula repairs, and 3 of them had undergone three attempts for closure. Fistula repairs were similar in all cases. The repair was successful in 6 out of 7 cases, and in these cases the urinary stream was good after the removal of the catheter. The unsuccessful case was the coronal one. Based on our experience it seems that in cases with recurrent large fistula after hypospadias reconstruction, the use of buccal mucosa patch graft for closure is a good treatment choice.

In patients with Crohn's disease, perianal fistulas recur frequently, causing substantial morbidity. We performed a 12-patient, 6-month, phase 1 trial to determine whether autologous mesenchymal stem cells, applied in a bioabsorbable matrix, can heal the fistula. Fistula repair was not associated with any serious adverse events related to mesenchymal stem cells or plug placement. At 6 months, 10 of 12 patients (83%) had complete clinical healing and radiographic markers of response. We found placement of mesenchymal stem cell-coated matrix fistula plugs in 12 patients with chronic perianal fistulas to be safe and lead to clinical healing and radiographic response in 10 patients.

2013-01-01

Graves’ ophthalmopathy (GO) is one of the frequent manifestations of the disorder which is an inflammatory process due to fibroblast infiltration, fibroblast proliferation and accumulation of glycosaminoglycans. Eye irritation, dryness, excessive tearing, visual blurring, diplopia, pain, visual loss, retroorbital discomfort are the symptoms and they can mimic carotid cavernous fistulas. Carotid cavernous fistulas are abnormal communications between the carotid arterial system and the cavernous sinus. The clinical manifestations of GO can mimic the signs of carotid cavernous fistulas. Carotid cavernous fistulas should be considered in the differential diagnosis of the GO patients especially who are not responding to the standard treatment and when there is a unilateral or asymmetric eye involvement. Here we report the second case report with concurrent occurrence of GO and carotid cavernous fistula in the literature. PMID:23571267

Among the different factors described, nutritional support has been associated to prevention and management of enterocutaneous fistulae (ECF). To assess the influence that the parameters related to nutritional, clinical status, and surgical variables have on the occurrence of ECF. An observational case/control retrospective study was performed on patients admitted to the General and Digestive Surgery Department. The parameters analyzed were: diagnosis, body mass index (BMI), pathologic personal history, number of surgical interventions (SI) and complications (previous infection, bleeding, and ischemia). In patients with SI, we analyzed: number and type of SI, time until onset of nutritional support, and type of nutritional support. We performed a multiple logistic uni- and multivariate regression analysis by using the SPSSv.19.0 software. The primary diagnoses related to the occurrence of ECF were pancreatic pathology (OR = 5.346) and inflammatory bowel disease (IBD) (OR = 9.329). The surgical variables associated to higher prevalence of ECF emergency SI (OR = 5.79) and multiple SI (OR = 4.52). Regarding the nutritional variables, the late onset of nutrition (more than three days after SI) was associated to the occurrence of ECF (OR = 3.82). In surgical patients, early nutritional support , independently of the route of administration, decreases the occurrence of fistulae. Pancreatic pathology, IBD, emergency SI, and multiple SI were associated to higher prevalence of ECF. The variable hyponutrition appears as a risk factor that should be confirmed in further studies.

Transverse mucoperiosteal flap inset by rotation for cleft palate repair: technique and outcomes.

PubMed

Black, Jonathan S; Gampper, Thomas J

2014-01-01

Cleft palate is a relatively common deformity with various techniques described for its repair. Most techniques address the hard palate portion of the cleft with bilateral mucoperiosteal flaps transposed to the midline. This results in superimposed, linear closure layers directly over the cleft and may predispose the repair to oronasal fistula formation. This report details an alternative technique of flap rotation with an outcome analysis. A retrospective chart analysis was performed of all patients having undergone primary palatoplasty for cleft palate. Demographics and cleft Veau type were recorded. Postoperative speech outcomes were assessed by standardized speech evaluation performed by 2 speech language pathologists. The presence and location of oronasal fistulae was assessed and recorded by the surgeon and speech language pathologists in follow-up evaluations. The study revealed an overall incidence of velopharyngeal insufficiency of 5.7% using this surgical technique. It also revealed a fistula rate of 8.6%. Secondary surgery has been successful in those patients in which it was indicated. Eleven (31%) patients were diagnosed with Robin sequence. This technique demonstrates excellent early outcomes in a difficult subset of cleft patients including a high proportion of those with Pierre Robin sequence. The technique addresses the inherent disadvantages to a linear closure over the bony cleft. The variability in its design provides the surgeon another option for correction of this deformity.

2012-05-01

The aim of this study was to compare velopharyngeal closure between patients who underwent Furlow palatoplasty and two-flap palatoplasty. A retrospective review of 88 patients with incomplete palate cleft was performed. 48 patients (17 males; 31 females) aged 2-28 years received Furlow palatoplasty. 40 patients (17 males; 23 females) aged 2-21 years received two-flap palatoplasty. Velopharyngeal function was categorized as adequate, marginal or inadequate. Complications associated with the operation were documented. Statistically significant differences were not found amongst sex distribution, age at operation, follow-up time, and preoperative speech intelligibility. After primary repairs using Furlow and two-flap palatoplasty, the surgeon's incidence of postoperative palatal fistula was 0%. The complications were not significantly different between the two groups. The authors achieved the lowest reported incidence of postoperative palatal fistulas in primary Furlow palatoplasty. The outcomes of the velopharyngeal closure were better in patients who received Furlow palatoplasty (P<0.05). Furlow palatoplasty was more effective than two-flap palatoplasty in obtaining perfect velopharyngeal closure. A probable explanation may be that Furlow palatoplasty can reposition and overlap the divergent palatal muscle and lengthen the soft palate.

Primary peri-anal adenocarcinoma of intestinal type - a new proposed entity.

PubMed

Gill, Pelvender S; Wong, Newton A C S

2018-02-21

The currently recognised subtypes of anal canal/peri-anal adenocarcinoma are those arising from low rectal mucosa or columnar cuff, fistula-related tumours and anal gland carcinoma. This report presents two examples of a hitherto undescribed subtype of peri-anal adenocarcinoma with an intestinal phenotype. A 74-year-old man had a peri-anal tumour locally excised, whereas a 73-year-old female underwent an abdominoperineal resection for peri-anal Paget's disease with an underlying carcinoma. Neither patient had a history of perineal fistulae, Crohn's disease or previous gastrointestinal neoplasia, and neither showed clinical, radiological or endoscopic evidence of another abdominal or pelvic tumour. Both resection specimens contained adenocarcinoma, which were similar in demonstrating an intestinal morphology and CDX2 immunopositivity. The man has shown a disease-free outcome thus far, but the woman has suffered with nodal and pelvic recurrence within a few months of surgery. The name 'primary peri-anal adenocarcinoma of intestinal type' is proposed for this previously unrecognised subtype of perineal neoplasia. Awareness of its distinct existence - by recognising its intestinal morphology and immunophenotype while excluding metastasis from the intestinal tract - should help to collate data to determine its specific prognosis and to formulate its best management. © 2018 John Wiley & Sons Ltd.

The prevention and treatment of obstetric fistula still remains a concern and a challenge in low income countries. The objective of this study was to estimate the overall proportions of failure of fistula closure and incontinence among women undergoing repair for obstetric fistula in Guinea and identify its associated factors. This was a retrospective cohort study using data extracted from medical records of fistula repairs between 1 January 2012 and 30 September 2013. The outcome was the failure of fistula closure and incontinence at hospital discharge evaluated by a dye test. A sub-sample of women with vesicovaginal fistula was used to identify the factors associated with these outcomes. Overall, 109 women out of 754 (14.5 %; 95 % CI:11.9-17.0) unsuccessful repaired fistula at discharge and 132 (17.5 %; 95 % CI:14.8-20.2) were not continent. Failure of fistula closure was associated with vaginal delivery (AOR: 1.9; 95 % CI: 1.0-3.6), partially (AOR: 2.0; 95 % CI: 1.1-5.6) or totally damaged urethra (AOR: 5.9; 95 % CI: 2.9-12.3) and surgical repair at Jean Paul II Hospital (AOR: 2.5; 95 % CI: 1.2-4.9). Women who had a partially damaged urethra (AOR: 2.5; 95 % CI: 1.5-4.4) or a totally damaged urethra (AOR: 6.3; 95 % CI: 3.0-13.0) were more likely to experience post-repair urinary incontinence than women who had their urethra intact. At programmatic level in Guinea, caution should be paid to the repair of women who present with a damaged urethra and those who delivered vaginally as they carry greater risks of experiencing a failure of fistula closure and incontinence.

Purpose: We aim to present our experience for the repair of vesicovaginal fistula (VVF) with special reference to surgical approach. Materials and Methods: From January 1999 to June 2005, 52 VVF patients with mean age of 32 years underwent operative treatment. Fistulas were divided into two groups, simple and complex, depending on site, size, etiology and associated anomalies. Simple VVFs were approached through the vaginal route and complex VVFs via the transabdominal route. Patients were evaluated at two to three weeks initially, three-monthly twice and later depending on symptoms. Results: Thirty-two (61.5%) had simple fistulas and 20 (38.5%) complex fistulas. The most common etiology was obstetric trauma in 31 (59.6%) patients, while the second most common cause was post hysterectomy VVF. Thirty-two (61.5%) patients were managed by transvaginal route, of which 17 had supratrigonal and 15 trigonal fistulas. Twenty (38.5%) patients with complex fistulas were managed by abdominal route. The mean blood loss, postoperative pain and mean hospital stay were shorter in transvaginal repair. Eleven (21.2%) patients required ancillary procedures for various other associated anomalies at the time of fistula repair. Three patients failed repair giving a success rate of 94.2%. At a mean follow-up of three years 48 women were sexually active, of these 10 (19.2%) complained of mild to moderate dyspareunia. Conclusion: Most of the simple fistulas irrespective their locations are easily accessible transvaginally while in complex fistulas we recommend the transabdominal approach. Depending on the clinical context both the approaches achieved comparable success rates. PMID:19718291

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

Malignant transformation of perineal fistula in Crohn's disease has rarely been reported. The aim of this study is to define the patient's characteristics and clinical presentation of this rare disease. A systematic review of case series and reports published in English language between 1950 and 2008 was conducted. All cases with malignancy in low pelvic/perineal fistula in patients with Crohn's disease were included. All selected cases were then analyzed with respect to age, gender, duration of Crohn's disease and fistula, location of fistula, presenting symptoms, method of diagnosis, delay in diagnosis, histopathology, treatment, and outcome. Data analyses were done using chi-squared or Fisher's exact test and the Mann-Whitney test. Literature review revealed 61 cases of carcinomas arising in perineal fistulas in Crohn's disease. Sixty-one percent (37) of the patients were females. Females were significantly younger than males at the time of diagnosis of cancer (47 vs. 53 years, P < 0.032). Males were also noted to have significantly longer duration of Crohn's disease compared to females (24 vs. 18 years, P = 0.005). However, females were noted to have the fistula for significantly shorter duration prior to cancer transformation when compared to males (8.3 vs. 16 years, P = 0.0035). On initial examination, malignancy was suspected and proven only in 20% of patients (n = 12). Adenocarcinoma was the most common histology (59%, n = 36), followed by squamous cell carcinoma (31%, n = 19). In most patients (59%, n = 36), the fistula was rectal in origin. A high suspicion for malignancy in chronic perineal fistulas associated with Crohn's disease should be maintained in spite of negative biopsies. Especially in women, the shorter duration of Crohn's fistulas prior to malignant degeneration necessitates an aggressive approach to rule out cancer.

Patient Male, 32 FINAL DIAGNOSIS: Dural arterio-venous fistula Symptoms: Eye redness • post-trauma headache • tinnitus - Clinical Procedure: Fistula embolization Specialty: Neurology. Mistake in diagnosis. A dural arteriovenous fistula (DAVF), is an abnormal direct connection (fistula) between a meningeal artery and a meningeal vein or dural venous sinus. The pathogenesis of DAVF still remains unclear. Sinus thrombosis, head trauma, chronic central nervous system, hypercoagulable state, surgery, and hormonal influence are the pre-disposing factors that initiate this disease. The symptoms experienced by the patient will depend on the location of the fistula. Thirty-two year old Hispanic male who presented one day after a rear ended motor vehicle collision (MVC) with a severe throbbing headache in the left parietal region, left eye redness but no retro-orbital pain and tinnitus in the left ear. He was initially misdiagnosed to have a carotid-cavernous fistula but upon cerebral angiogram was actually diagnosed with a dural arterio-venous fistula in the posterior fossa venous system followed by successful embolization of the fistula. A cerebral angiography is the gold standard for detection and characterization of a DAVF and will distinguish it from a CCF. Endovascular surgery involves a catheter-based technique for embolization of the lumen of arteries feeding the DAVF, or directly into the vein draining the DAVF. It is very important to recognize the typical findings of patients presenting with a DAVF then quickly proceeding with a cerebral angiogram to determine the exact location of the fistula and the appropriate treatment plan. By diagnosing and treating a DAVF as early as possible, the associated fatal complications can be averted.

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

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.

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. PMID:25187726

Summary Background and objectives Guidelines promote early fistula creation to avoid central venous catheter use. This practice may lead to fistula creations in patients who never receive dialysis. The objective of this study was to estimate the risk of fistula nonuse with long-term follow-up. Design, setting, participants, & measurements Administrative health data identified 1929 predialysis adults who had their first fistula creation between April of 2002 and March of 2006. Patients were followed for a minimum of 2 years or until they began dialysis, received a kidney transplant, or died. Results The median follow-up times in patients who started dialysis, died without receiving dialysis, and remained in predialysis were 6.1, 11.5, and 38.7 months, respectively. Eighty-one percent of patients initiated dialysis; 9% of patients died without receiving dialysis, and 10% of patients remained predialysis. Forty percent of patients had their first fistula creation 3–12 months before initiating dialysis (the recommended window). Thirty percent were created within 90 days of starting dialysis; 30% were created more than 1 year before starting dialysis, and 10% were created more than 2 years before starting dialysis. Older patients, females, and patients with less comorbidity were not as likely to initiate dialysis after incident fistula creation. Conclusions Most patients who underwent fistula creation before starting dialysis eventually received dialysis with extended follow-up, but the risk was significantly modified by age, sex, and comorbidity. Many patients had fistula creations earlier or later than recommended. PMID:22344512

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

Anal fistula (AF) is a pathological connection between anus and skin in its surroundings. The main reason for the formation of anal fistula is a bacterial infection of the glands within the anal crypts. One of the modern techniques for the treatment of fistulas that do not interfere with the sphincters consists in implantation of a plug made from collagen material. We are presenting the first Polish experience with a new model of biomaterial plug for the treatment of anal fistula. We also point out key elements of the procedure (both preoperative and intraoperative) associated with this method. In the authors' opinion, the method is simple, safe and reproducible. Innovative shape of the plug minimizes the risk of its migration and rotation. It also perfectly blends with and adapts to the course and shape of the fistula canal, allowing it to become incorporated and overgrown with tissue in the fistula canal. The relatively short operation time, minor postoperative pain and faster convalescence are with no doubt additional advantages of the method. Long-term observation involving more patients is essential for evaluation of the efficacy of the treatment of fistulas with the new type of plug.

The two sides of the coin: Similarities and differences in the pathomechanisms of fistulas and stricture formations in irritable bowel disease.

Fistulas and fibrosis or strictures represent frequent complications in irritable bowel disease (IBD) patients. To date, treatment options for fistulas are limited and surgery is often required. Similarly, no preventive treatment for fibrosis and stricture formation has been established. Frequently, stricture formation and fibrosis precede fistula formation, indicating that both processes may be connected or interrelated. Knowledge about the pathology of both processes is limited. A crucial role for the epithelial-to-mesenchymal transition (EMT) in fistula development has been demonstrated. Of note, EMT also plays a major role in the pathogenesis of fibrosis in many organs, and most likely also plays that role in the intestine. In addition, aberrant matrix remodeling, as well as soluble factors such as tumor necrosis factor (TNF), interleukin 13 (IL-13) and tumor growth factor beta (TGFβ) were involved, both in the onset of the fistula and fibrosis formation. Both fistulas and fibrosis may occur due to deregulated wound healing mechanisms from chronic and severe intestinal inflammation; however, further research is required to obtain a better understanding of the complex pathophysiology of fistula and intestinal fibrosis formation, to allow the development of new and more effective preventive treatment options for those important disease complications.

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.

Provision of a summary on the physiologic effects of arteriovenous fistula creation and description of previously published human data on the efficacy of a percutaneously implanted device creating an arteriovenous fistula. Though antihypertensive therapy is effective, some patient's blood pressure remains poorly controlled despite adherence to optimal medical therapy. Moreover, some patients are not compliant with recommended medical therapy due to side effects or personal decision. This has prompted exploration of alternative, device-based antihypertensive therapies including, among others, the percutaneous creation of an arteriovenous fistula. An arteriovenous fistula is accompanied by a number of favorable physiologic changes that may lower blood pressure. These physiologic changes, conduction of the procedure, and previously published human experience are summarized in this review article. The results of a recently published trial comparing arteriovenous fistula creation and standard antihypertensive therapy versus standard antihypertensive therapy alone are summarized. Creation of an arteriovenous fistula is accompanied by a significant blood pressure reduction likely related to a reduction in total arterial resistance, perhaps blood volume reduction, inhibition of the baroreceptor reflex, and release of natriuretic peptides. These findings foster further interest in studying the impact of an arteriovenous fistula and arterial blood pressure. The design of a large randomized trial comparing arteriovenous fistula creation to sham control is outlined.

The vesicovaginal fistula from prolonged obstructed labor is a condition that is no longer seen in the affluent, industrialized world, yet it continues to exist in epidemic proportions in sub-Saharan Africa, where several million women are estimated to suffer from this condition. The unremitting urinary incontinence that is produced by a fistula causes these women to become social outcasts. The problem is particularly acute in Nigeria, where the Federal Ministry of Women's Affairs estimates that there may be as many as 800,000 unrepaired fistula cases. Because of the social stigma attached to their condition, fistula victims have often been subjected to major psychosocial trauma. Finding ways to help such patients reintegrate into social networks is an important part of their treatment. When fistula patients meet one another, they realize that they are not alone in their suffering. This article describes the use of a "praise song" by a group of Nigerian fistula patients as a vehicle for building group identity as part of a "sisterhood of suffering." A transcription and translation of a Hausa praise song about vesicovaginal fistulas is presented, along with a commentary on the text that sheds new light on a problem that is unfamiliar to most Western obstetrician-gynecologists.

Postoperative residual shunting is a significant concern in patients with coronary arteriovenous fistulas, especially in fistulas originating from the proximal left coronary artery, because of the limited surgical field. We report a case of fistulas originating from the proximal coronary artery in a 63-year-old woman in whom the ascending aorta and pulmonary artery were transected to obtain good surgical exposure. After complete transection of both great arteries, fistulas arising from the left main trunk were ligated externally, and their intracardiac openings were closed internally. Postoperative examination revealed no residual shunt flow. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Transarterial Embolization of a Spontaneous Intraorbital Arteriovenous Fistula With n-BCA Glue.

Konstas, Angelos A; Rootman, Daniel B; Quiros, Peter A; Ross, Ian B

Arteriovenous fistulae of the orbit are exceedingly rare. They are high-flow vascular malformations involving a fistula from the ophthalmic artery to one of the draining ophthalmic veins. Presenting symptoms can mimic those of carotid cavernous fistulae or of ophthalmic venous varices, and include diplopia, proptosis, chemosis, decreased visual acuity, and retro-orbital pain. Very few case reports are published on the treatment of this aggressive vascular malformation, and they uniformly describe techniques involving a transvenous access for the embolization of the fistula. To the best of authors' knowledge, they report the first case of transarterial embolization of an intraorbital AVF.

Congenital tracheo-or-bronchobiliary fistula or congenital he-patopulmonary fistula is a rare malformation with high morbidity and mortality if the diagnosis is not made early. The tracheo-or-bronchobiliary fistula is a communication between the respiratory (trachea or bronchus) and biliary tract. To date, only 35 cases have been published worldwide. We report a case of a neonate with right pneumonia and bilious fluid in the endotracheal tube. Diagnosis was made using bronchoscopy with fluoroscopy. Videothoracoscopy was used to remove the bronchobiliary fistula. Subsequently, a left he-patectomy with Roux-en-Y biliary-digestive anastomosis was performed as bile ductus hypoplasia was present.

Ureteral stents and ureteral catheters externalized through the urethra are not ideal solutions to manage complicated upper urinary tract fistulae. We sought an effective method of drainage, minimally invasive, reproducible allowing a rapid patient's discharge. Between November 2013 and February 2015, an ureteral stent was exteriorized in trans-vesico-parietal by an endoscopic and percutaneous access in patients with complicated upper urinary tract fistulae. Monitoring of tolerance, complications and urinary fistula healing was performed. Nine consecutive patients had an ureteral stent exteriorized in trans-vesico-parietal to manage complicated upper urinary tract fistulae. There was no failure in introducing the catheter, or postoperative complication. Catheters were left in place on average 36.1days (24-55). The patients were able to return home with the catheter in place in 77.8% of cases. The tolerance of the catheter was good. All fistulae were able to be treated conservatively at the end of the drainage period. Trans-vesico-parietal ureteral catheters enable efficient and reproducible conservative treatment of upper tract urinary fistulae regardless of their cause. 5. Copyright © 2016 Elsevier Masson SAS.

2018-01-03

Spontaneous right hepatic artery branch gallbladder fistula is a rare condition. Our case reported a spontaneous fistula between the right branch of the hepatic artery and the gall bladder. It constitutes a rare cause of haemobilia. In fact, the most common aetiology of haemobilia is traumatic or iatrogenic secondary to hepatobiliary surgery or interventions. Diagnosis of vascular-biliary fistula is not easy. The gallbladder endoluminal clot can mimic a mass, as in our patient. Selective arterial angiography is helpful in identifying the source of gastrointestinal haemorrhage. It can demonstrate the presence of arteriobiliary fistula. The differential diagnosis is arterial pseudoaneurysm in the vicinity of the vessel. Mini-invasive treatment of this fistula constitutes the best treatment. We here report a case of haemobilia with upper cataclysmic gastrointestinal bleeding revealing a spontaneous fistula between the right branch of the hepatic artery and the gall bladder. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

This article presents findings from qualitative interviews with women seeking medical care for obstetric fistula in Eritrea. The interviews were designed to inform programme design for the prevention and treatment of obstetric fistula. Interviews were conducted with 11 new fistula repair patients, 15 women returning for follow-up for their fistula repairs, and five accompanying family members at Massawa Hospital in the Northern Red Sea Zone of Eritrea during November-December 2004. The women described long delays in accessing emergency obstetric care due to delayed recognition of the seriousness of the problem and lack of transportation from remote villages. Follow-up patients described improvements in their conditions, but many continued to have problems with incontinence and sexual health. Both new and returning patients lacked specific information about their condition, what to expect in terms of treatment and recovery, and how to care for themselves. The findings point to a need for community mobilization and education on safe motherhood for prevention of fistula, as well as for improved information, counselling, follow-up, and social services for women who develop obstetric fistulas.

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

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 experienced sacrifice of the parent vessels and it was associated with sizes of the fistula. Total severe complication was about 2.4% which included 1 death (0.6%) due to vagal shock; 1 transient hemiparesis post-sacrifice occlusion of the carotid artery but the patient had recovered after 3 months; 1 acute thrombus embolism and the patient was completely saved with recombinant tissue plaminogen activator (rTPA); 1 balloon dislodgement then got stuck at the anterior communicating artery but the patient was asymptomatic. Endovascular intervention as the treatment of direct traumatic CCF had high cure rate and low complication with its ability to preserve the carotid artery. It also can supply flexible accesses to the fistulous site with various alternative embolic materials. The new classification of type A CCF based on angiographic features was helpful for planning for the embolization. Coil should be considered as the first embolic material for small size fistula meanwhile detachable balloons was suggested as the first-choice embolic agent for the medium and large size fistula.

A two-year-old neutered/male mixed-breed dog had received partial maxillectomy for fibrosarcoma. An oronasal fistula occurred as a complication of the surgical procedure. An island palatal mucoperiosteal flap was developed and rotated to repair the oronasal fistula. Acute (1-month) and long-term (8-months) follow-up indicated appropriate healing of the transposed island palatal mucoperiosteal flap with resolution of clinical signs indicative of oronasal fistula.

To evaluate efficacy and cost of using cyclosporine and ketoconazole for the treatment of perianal fistulas in dogs. Clinical trial. 12 dogs with perianal fistulas. Dogs received cyclosporine and ketoconazole orally (target whole blood trough cyclosporine concentrations of 400 to 600 ng/ml). Study endpoints were resolution of clinical signs, remission, and recurrence of disease. Adverse effects and cost of medications were reported. Results were compared with those from previous studies in humans and in dogs in which single agent cyclosporine treatment for perianal fistulas was used. All dogs had resolution of clinical signs. Eight dogs went into remission; however, 5 of those 8 had recurrence of fistulas. Adverse effects of treatment were minimal and well tolerated. Cost of treatment was comparable to traditional surgical options and less than single agent cyclosporine treatment. Administration of cyclosporine with ketoconazole is an effective and cost-comparable treatment for perianal fistulas in dogs.

Pharmaconutrition, which is a supportive nutritional care of surgical patients, has been proven to shorten hospital stay, decrease the incidence of infection, and reduce hospital costs in selected groups of patients. Arginine, one of the most essential pharmaconutrients, has also been proven to enhance would healing process. In severely malnourished patients like bronchopleural fistula with resultant empyema, aggressive nutritional approach should be mandatory. And management of the fistula is also important in stabilizing the ongoing infection. Our hypothesis was that basic nutritional support enhanced with arginine would be effective in not only improving the general condition including nutritional status but also in healing the fistula. We report a case of major bronchopleural fistula in which arginine-supplemented diet as well as aggressive nutritional support could accelerate the postoperative recovery after open thoracic window, ultimately leading to the healing of the fistula.

To evaluate the incidence of pharyngocutaneous fistula after total laryngectomy and try to identify its predictors. From May 2005 to April 2010, 93 patients underwent total laryngectomy. We evaluated complications during and after surgery and compared them with the following variables: gender, nutritional status, previous tracheotomy, tumor location, type of surgery, TNM staging, prior treatment with chemotherapy and/or radiotherapy, use of flaps for reconstruction and surgical margin. All patients presented with advanced neoplastic disease according to TNM. 14 (15.1%) patients developed postoperative salivary fistula. The mean time to onset of salivary fistula was 3.5 days, with a standard deviation of 13.7 days. Comparing salivary fistula with TNM variables, type of operation and neck dissection, prior tracheotomy, use of flap, preoperative radio and chemotherapy and surgical margin, there was no statistically significant difference (p> 0,05). The incidence of salivary fistula was 15.1% and no predictive factor for its formation was found.

Spacer Facial Artery Musculomucosal Flap: Simultaneous Closure of Oronasal Fistulas and Palatal Lengthening.

Lee, Jonathan Y; Alizadeh, Kaveh

2016-01-01

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

Management of a complicated pulmonary fistula caused by lung cancer using a fibrin glue-soaked polyglycolic acid sheet covered with an intercostal muscle flap.

Pulmonary fistulas caused by tumours are very fragile and difficult to suture directly. It is impossible to close pulmonary fistulas with tissue sealants when massive air leakage occurs in the low pressure of the respiratory tract. A 73-year-old man with a pneumothorax caused by lung cancer had suffered a persistent massive air leakage for more than one month. We used a fibrin glue-soaked polyglycolic acid (PGA) sheet for sealing the complicated fistula. In addition, the visceral pleura of the fistula was wrapped with the pedicle of an intercostal muscle (ICM) flap to prevent massive air leakage. The pneumothorax did not reappear after surgery. Thus, a fibrin glue-soaked PGA sheet covered with an ICM flap was effective for sealing an intractable air-leaking fistula caused by lung cancer.

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

Anal fistula with foot extension—Treated by kshara sutra (medicated seton) therapy: A rare case report

PubMed Central

Ramesh, P. Bhat

2013-01-01

INTRODUCTION An ‘anal’ fistula is a track which communicates anal canal or rectum and usually is in continuity with one or more external openings. Distant communication from rectum is rare. It is a challenging disease because of its recurrence especially, with high level and distant communications. Ksharasutra (medicated seton) therapy is being practiced in India with high success rate (recurrence of 3.33%) in the management of complicated anal fistula. PRESENTATION OF CASE A 56 year old man presented with recurrent boils in the left lower limb at different places from thigh to foot. He underwent repeated incision and drainage at different hospitals. Examination revealed sinus with discharge and multiple scars on left lower limb from thigh up to foot. Suspecting anal fistula, MRI was advised which revealed a long cutaneous fistula from rectum to left lower limb. Patient was treated with Ksharasutra therapy. Within 6 months of treatment whole tract was healed completely. DISCUSSION Sushrutha (500BC) was the first to explain the role of surgical excision and use of kshara sutra for the management of anal fistula. Ksharasutra therapy showed least recurrence. Fistula from rectum to foot is of extremely rare variety. Surgical treatment of anal fistula requires hospitalization, regular post-operative care, is associated with a significant risk of recurrence (0.7–26.5%) and a high risk of impaired continence (5–40%). CONCLUSION Rectal fistula communicating till foot may be a very rare presentation in proctology practice. Kshara sutra treatment was useful in treating this condition, with minimal surgical intervention with no recurrence. PMID:23702360

this study aimed to gain understanding of the views of community members in relation to obstetric fistula. a qualitative, grounded theory approach was adopted. Data were collected using in-depth interviews with 45 community members. The constant comparison method enabled generation of codes and subsequent conceptualisations, from the data. participants were from communities served by two hospitals in Kenya; Kisii and Kenyatta. Interviews took place either in the home, place of work, or hospital. the core category (central concept) is 'secrecy hinders support'. This was supported by three themes: 'keeping fistula hidden', 'treatment being a lottery' and 'multiple barriers to support.' These themes represent the complexities around exposure of individual fistula sufferers and the impact that lack of information and women's status can have on treatment. Keeping fistula secret reinforces uncertainties around fistula, which in itself fuels myths and ignorance regarding causes and treatments. Lack of openness, at an individual level, prevents support being sought or offered. A multi-layered strategy is required to support women with fistula. At a societal level, the status of women in LMIC countries needs elevation to a level that provides equity in health services. At a national level, laws need to protect vulnerable women from mistreatment as a direct result of fistula. Furthermore, resources should be available to ensure provision of timely management, as part of routine services. At community level, awareness and education is required to actively engage members to support women locally. Peer support before and after fistula repair may be beneficial, but requires further research. Copyright © 2016 Elsevier Ltd. All rights reserved.

Use of an Amplatzer Device for Endoscopic Closure of a Large Bronchopleural Fistula following Lobectomy for a Stage I Squamous Cell Carcinoma.

Bronchopleural fistulas can occur as a rare but severe complication after pulmonary resection. Established guidelines for the proper treatment of patients with bronchopleural fistulas do not exist. Apart from attempts to close the fistula, emphasis is placed on preventive measures, early treatment with antibiotics, drainage of the empyema and aggressive nutritional and rehabilitative support. For inoperable patients, endoscopic procedures are the only therapeutic option. Unfortunately, large (>8 mm) or central bronchopleural fistulas are usually not suitable for such endoscopic management. Recently, some groups have published a few case reports about a novel technique for the endobronchial closure of bronchopleural fistulas, using an Amplatzer device, originally designed for transcatheter closure of cardiac septal defects. We applied the same technique as a life-saving treatment in a ventilated patient who was considered inoperable due to a high oxygen need. The operation was successful. The patient could be weaned from ventilation and was eventually discharged from the hospital to a rehabilitation facility several weeks after the insertion of the device. Until now, endoscopic techniques have only been useful for the treatment of small, peripheral, bronchopleural fistulas and even then only as a bridge to surgery in high-risk surgical patients. In this case report, we demonstrate that the use of an Amplatzer device can expand the importance of endoscopic techniques in the treatment of bronchopleural fistulas. An Amplatzer device, for endobronchial closure, can indeed be administered for large and central bronchopleural fistulas. Moreover, it can be considered as a definite alternative to surgery in inoperable patients.

[Treatment of enteric fistula in open abdomen].

PubMed

Evenson, R A; Fischer, J E

2006-07-01

Formation of enteric fistulas frequently complicates the open abdomen in patients who have sustained traumatic injury. The post-traumatic subset of patients with enterocutaneous fistula enjoy better than average recovery. To optimize this recovery, a systematic management approach is required. Patients must first be stabilized with nutritional support, control of sepsis, and special wound management systems to prevent further deterioration of the abdominal wall. Investigation of the origin, course, and characteristics of the fistula provides information about its likelihood to close without operation. Definitive operative therapy may be necessary to resolve the fistula and close the abdominal wall. Finally, healing support includes nutritional support and physical and occupational therapies to restore patients to pre-injury states.

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.

A 29-year-old healthy woman bore monozygotic male twins at 37 weeks of gestation by cesarean section. They weighed 2,350 and 2,140 g, respectively. Twin B was found to have a ventricular septal defect. They were diagnosed with esophageal atresia (EA) with tracheoesophageal fistula and underwent primary end-to-end esophageal anastomosis at the age of 1 day. Their postoperative courses were uneventful. Although the incidence of EA is higher in twins than in singletons, usually, EA affects only one of twins. There have been only 20 pairs of twins concordant for the EA anomaly. There is no distinct difference between sporadic EA and EA in both twins (EABT) with regard to sexuality, classification, and incidence of associated anomalies. The zygosity of EABT consisted of 15 monozygosities (83.3%) and 3 dizygosities (16.7%). An overwhelmingly higher incidence of monozygosity than that of dizygosity in EABT suggests that genetic factors must play a considerable role in the embryology in EABT cases.

Multiple left anterior descending coronary artery to left ventricular fistula - A case series and literature review.

PubMed

Iyer, Praneet; Yelisetti, Rishitha

2017-10-01

Coronary artery fistulas (CAFs) are found in 0.3-0.8% of patients who undergo coronary angiography. CAFs are defined as single or multiple, small or large direct communications that arise from one or more coronary arteries and enter into one of the four cardiac chambers or major vessels. We present two cases of multiple coronary artery fistulas arising from diagonal and left anterior descending (LAD) branches of left coronary artery draining into the left ventricle. In both the cases, No intervention was performed. Of the congenital fistulas, two major groups are identified: solitary CAFs or coronary artery-left ventricular multiple micro-fistulas (CALVMMFs). Noninvasive techniques such as transthoracic echocardiography, transesophageal echocardiography and magnetic resonance imaging are becoming increasingly popular for diagnosis and follow-up of CAFs. Despite the advent of these newer non-invasive modalities, coronary angiography remains the gold standard for diagnosis. Treatment of CAFs is indicated when the patients are symptomatic with left ventricular volume overload, myocardial ischemia, left ventricular dysfunction or in the presence of a large or increasing left-to-right shunt. If the fistula is small and hemodynamically insignificant, it can be managed with conservative management. Multiple left anterior descending to left ventricle (LV) fistulas are extremely rare and, as per our literature review, we noted only a few case reports of coronary artery fistulas between branches of LAD and left ventricle.

High intensity focused ultrasound (HIFU) has come forward as alternative treatment for carcinoma of the prostate. Though minimally invasive,HIFUhas potential side effects. Urethrorectal fistula is one such rare side effect. Management of these fistulas has been described by Vanni et al. This case report describes points of technique that will help successful management of resilient rectourethral fistula. Urinary and faecal diversion in the form of suprapubic catheter and colostomy is vital. Adequate time between stoma formation, fistula closure and then finally stoma closure is needed. Lithotomy position and perineal approach gives best exposure to the fistula. The rectum should be dissected 2cm above the fistula; this aids in tension free closure of the rectal defect. Similarly buccal mucosal graft was used on the urethra to achieve tension free closure. A good vascular pedicle gracilis muscle flap is used to interpose between the two repairs. This not only provides a physical barrier but also provides a vascular bed for BMG uptake. Perfect haemostasis is essential, as any collection may become a site of infection thus compromising results.  We strongly recommend rectourethral fistula be directly repaired with gracilis muscle flap with reinforced buccal mucosa graft without attempting any less invasive repairs because the "first chance is the best chance".

2006-11-01

The vesico-vaginal fistula from prolonged obstructed labor has become a rarity in the industrialized West but still continues to afflict millions of women in impoverished Third World countries. As awareness of this problem has grown more widespread, increasing numbers of American and European surgeons are volunteering to go on short-term medical mission trips to perform fistula repair operations in African and Asian countries. Although motivated by genuine humanitarian concerns, such projects may serve to promote 'fistula tourism' rather than significant improvements in the medical infrastructure of the countries where these problems exist. This article raises practical and ethical questions that ought to be asked about 'fistula trips' of this kind, and suggests strategies to help insure that unintended harm does not result from such projects. The importance of accurate data collection, thoughtful study design, critical ethical oversight, logistical and financial support systems, and the importance of nurturing local capacity are stressed. The most critical elements in the development of successful programs for treating obstetric vesico-vaginal fistulas are a commitment to developing holistic approaches that meet the multifaceted needs of the fistula victim and identifying and supporting a 'fistula champion' who can provide passionate advocacy for these women at the local level to sustain the momentum necessary to make long-term success a reality for such programs.

To evaluate the prevalence of fistulas after palate repair and analyze their location and association with possible causal factors. Retrospective analysis of patient records and evaluation of preoperative initial photographs. Tertiary craniofacial center. Five hundred eighty-nine individuals with complete unilateral cleft lip and palate that underwent palate repair at the age of 12 to 36 months by the von Langenbeck technique, in a single stage, by the plastic surgery team of the hospital, from January 2003 to July 2007. The cleft width was visually classified by a single examiner as narrow, regular, or wide. The following regions of the palate were considered for the location: anterior, medium, transition (between hard and soft palate), and soft palate. Descriptive statistics and analysis of association between the occurrence of fistula and the different parameters were evaluated. Palatal fistulas were observed in 27% of the sample, with a greater proportion at the anterior region (37.11%). The chi-square statistical test revealed statistically significant association (P ≤ .05) between the fistulas and initial cleft width (P = .0003), intraoperative problems (P = .0037), and postoperative problems (P = .00002). The prevalence of palatal fistula was similar to mean values reported in the literature. Analysis of causal factors showed a positive association between palatal fistulas with wide and regular initial cleft width and intraoperative and postoperative problems. The anterior region presented the greatest occurrence of fistulas.

External pancreatic fistula (EPF) is a common sequel to surgical or percutaneous intervention for infective complications of acute severe pancreatitis. The present study was aimed at studying the clinical profile, course and outcome of patients with EPF following surgical or percutaneous management of these infective complications. A retrospective analysis of clinical data of patients with EPF following intervention (surgical or percutaneous) for acute severe pancreatitis managed between January 1989 and April 2002 recorded on a prospective database was done. Univariate analysis of various factors (etiology, imaging findings prior to intervention, fistula characteristics and management) that could predict early closure of fistula was performed. Of 210 patients with acute severe pancreatitis, 43 (20%) patients developed EPF (mean age 38 (range 16-78) years, M:F ratio 5:1) following intervention for infected pancreatic necrosis (n=23) and pancreatic abscess (n=20) and constituted the study group. The fistula output was categorized as low (<200 ml), moderate (200-500 ml) and high (>500 ml) in 29 (67%), 11 (26%) and 3 (7%) patients, respectively. Fifteen patients (35%) had morbidity in the form of abscess (n=5), bleeding (n=1), pseudoaneurysm (n=2) and fever with no other focus of infection (n=7). Spontaneous closure of the fistula occurred in 38 (88%) patients. The average time to closure of fistula was 109+/- 26 (median 70) days. Fistula closed after intervention in 5 patients (2 after endoscopic papillotomy, 1 after fistulojejunostomy and 2 after downsizing the drains). Of the 38 patients with spontaneous closure, 9 (24%) patients developed a pseudocyst after a mean interval of 123 days of which 7 underwent surgical drainage of the cyst. Univariate analysis of various factors (etiology, imaging findings prior to intervention, fistula characteristics and management) failed to identify any factors that could predict early closure of fistula. EPF is a common sequel following intervention in acute severe pancreatitis. The majority of these are low output fistulae and close spontaneously with conservative management. One-fourth of patients with spontaneous closure develop a pseudocyst as a sequel, requiring surgical management. Copyright (c) 2005 S. Karger AG, Basel.

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

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

Internal obturator and/or semitendinosus muscle flaps were used to reinforce primary appositional rectal wall repair in three dogs and one cat in this case series. All three dogs incurred rectal wall compromise during surgical excision of anal sac tumours. The cat sustained bite wounds to the perianal region resulting in abscessation and a rectal tear. Our results indicate that application of an internal obturator and/or semitendinosus muscle flap can reduce the risk of rectal wall dehiscence after primary repair, and consequently the risk of pararectal abscess or rectocutaneous fistula formation. © 2018 British Small Animal Veterinary Association.

While very rarely reported, duodenocutanenous fistula research might alter the duodenal ulcer disease background and therapy. Our research focused on rat duodenocutaneous fistulas, therapy, stable gastric pentadecapeptide BPC 157, an anti-ulcer peptide that healed other fistulas, nitric oxide synthase-substrate L-arginine, and nitric oxide synthase-inhibitor L-nitro-arginine methyl ester (L-NAME). The hypothesis was, duodenal ulcer-healing, like the skin ulcer, using the successful BPC 157, with nitric oxide-system involvement, the "wound healing-therapy", to heal the duodenal ulcer, the fistula-model that recently highlighted gastric and skin ulcer healing. Pressure in the lower esophageal and pyloric sphincters was simultaneously assessed. Duodenocutaneous fistula-rats received BPC 157 (10 μg/kg or 10 ng/kg, intraperitoneally or perorally (in drinking water)), L-NAME (5 mg/kg intraperitoneally), L-arginine (100 mg/kg intraperitoneally) alone and/or together, throughout 21 days. Duodenocutaneous fistula-rats maintained persistent defects, continuous fistula leakage, sphincter failure, mortality rate at 40% until the 4(th) day, all fully counteracted in all BPC 157-rats. The BPC 157-rats experienced rapidly improved complete presentation (maximal volume instilled already at 7(th) day). L-NAME further aggravated the duodenocutaneous fistula-course (mortality at 70% until the 4(th) day); L-arginine was beneficial (no mortality; however, maximal volume instilled not before 21(st) day). L-NAME-worsening was counteracted to the control level with the L-arginine effect, and vice versa, while BPC 157 annulled the L-NAME effects (L-NAME + L-arginine; L-NAME + BPC 157; L-NAME + L-arginine + BPC 157 brought below the level of the control). It is likely that duodenocutaneous fistulas, duodenal/skin defect simultaneous healing, reinstated sphincter function, are a new nitric oxide-system related phenomenon. In conclusion, resolving the duodenocutanenous fistulashealing, nitric oxide-system involvement, should illustrate further wound healing therapy to heal duodenal ulcers.

To share our experience involving seven patients with type II first branchial cleft anomalies (hereafter, type II anomalies), to determine whether the location of the external fistula openings of the anomalies are associated with the location of the facial nerve tract, and elucidate the relationship between the location of the fistula opening and the facial nerve. The medical records of seven patients who underwent surgery from 2005 to 2013 for type II anomalies were retrospectively examined. The relationship between the fistula opening and the facial nerve was evaluated in each patient with respect to whether the fistula opening was superior or inferior to the mandibular angle. All patients underwent partial parotidectomy, facial nerve exposure, and total excision of the mass together with connection of a small cuff of the external auditory canal skin to the fistula tract. The fistula tracts were located medially to the facial nerve in two patients, and both fistulae had openings inferior to the mandibular angle. The fistula tracts were located laterally to the facial nerve in the remaining five patients: one patient had no external opening, one had an opening inferior to the mandibular angle, and the remaining three had openings superior to the mandibular angle. Because type II anomalies are rare, their diagnosis is difficult. Surgery of such lesions is challenging and associated with a high risk due to their proximity to the facial nerve. We believe that the location of the fistula opening may help to identify the relationship between the anomalous lesion and facial nerve. Studies involving larger series of cases are needed to confirm our hypothesis; however, because of the rarity of this specific anomaly, it will not be easy to compile a large number of cases. We believe that our study will encourage further investigation on this subject. Copyright © 2014. Published by Elsevier Ireland Ltd.

Objective To develop a risk score to identify women with vesicovaginal fistula at high risk of residual urinary incontinence after surgical repair. Methods We conducted a prospective cohort study among 401 women undergoing their first vesicovaginal fistula repair at a referral fistula repair center in Lilongwe, Malawi, between September 2011 and December 2014, who returned for follow-up within 120 days of surgery. We used logistic regression to develop a risk score to identify women with high likelihood of residual urinary incontinence, defined as incontinence grade 2-5 within 120 days of vesicovaginal fistula repair, based on preoperative clinical and demographic characteristics (age, number of years with fistula, HIV status, body mass index, previous repair surgery at an outside facility, revised Goh Classification, Goh vesicovaginal fistula size, circumferential fistula, vaginal scaring, bladder size, and urethral length). The sensitivity, specificity, positive and negative predictive values of the risk score at each cut-point were assessed. Results Overall, 11 (3%) women had unsuccessful fistula closure. Of those with successful fistula closure (n=372), 85 (23%) experienced residual incontinence. A risk score cut-point of 20 had sensitivity 82% (95% CI 72%, 89%) and specificity 63% (95% CI 57%, 69%) to potentially identify women with residual incontinence. In our population, the positive predictive value for a risk score cut-point of _20 or higher was 43% (95% CI 36%, 51%) and the negative predictive value was 91% (95% CI 86%, 94%). Forty-eight percent of our study population had a risk score ≥20 and therefore, would have been identified for further intervention. Conclusions A risk score 20 or higher was associated with an increased likelihood of residual incontinence, with satisfactory sensitivity and specificity. If validated in alternative settings, the risk score could be used to refer women with high likelihood of postoperative incontinence to more experienced surgeons. PMID:27741181

To present the management of open abdomen with colorectal fistula by application of intrarectal negative pressure system (NPS) in addition to abdominal NPS. Twenty-year old man had a history of injuries by a close-range gunshot to the abdomen eight days ago and he had been treated by bowel repairs, resections, jejunal anastomosis and Hartman's procedure. He was referred to our center after deterioration, evisceration with open abdomen and enteric fistula in septic shock. There were edematous, fibrinous bowels and large multiple fistulas from the edematous rectal stump. APACHE II, Mannheim Peritoneal Index and Björck scores were 18, 33 and 3, respectively (expected mortality 100%). After intensive care for 5 days, he was treated by abdominal and intrarectal NPS. NPS repeated for 5 times and the fistula was recovered on day 18 completely. Fascial closure was facilitated with a dynamic abdominal closure system (ABRA) and he was discharged on day 33 uneventfully. There was no herniation and any other problem after 12 months follow-up. Management of fistula in OA can be extremely challenging. Floating stoma, fistula VAC, nipple VAC, ring and silo VAC, fistula intubation systems are used for isolation of the enteric effluent from OA. Several biologic dressings such as acellular dermal matrix, pedicled flaps have been used to seal the fistula opening with various success. Resection of the involved enteric loop and a new anastomosis of the intestine is very hard and rarely possible. In all of these reports, usually patients are left to heal with a giant hernia. In contrast to this, there is no hernia in our case during one year follow up period. Combination of intra and extra luminal negative pressure systems and ABRA is a safe and successful method to manage open abdomen with colorectal fistula. Copyright © 2014 The Authors.

Sinus stenosis occasionally occurs in dural arteriovenous fistulas. Sinus stenosis impedes venous outflow and aggravates intracranial hypertension by reversing cortical venous drainage. This study aimed to analyze the likelihood of sinus stenosis and its impact on cerebral hemodynamics of various types of dural arteriovenous fistulas. Forty-three cases of dural arteriovenous fistula in the transverse-sigmoid sinus were reviewed and divided into 3 groups: Cognard type I, type IIa, and types with cortical venous drainage. Sinus stenosis and the double peak sign (occurrence of 2 peaks in the time-density curve of the ipsilateral drainage of the internal jugular vein) in dural arteriovenous fistula were evaluated. "TTP" was defined as the time at which a selected angiographic point reached maximum concentration. TTP of the vein of Labbé, TTP of the ipsilateral normal transverse sinus, trans-fistula time, and trans-stenotic time were compared across the 3 groups. Thirty-six percent of type I, 100% of type IIa, and 84% of types with cortical venous drainage had sinus stenosis. All sinus stenosis cases demonstrated loss of the double peak sign that occurs in dural arteriovenous fistula. Trans-fistula time (2.09 seconds) and trans-stenotic time (0.67 seconds) in types with cortical venous drainage were the most prolonged, followed by those in type IIa and type I. TTP of the vein of Labbé was significantly shorter in types with cortical venous drainage. Six patients with types with cortical venous drainage underwent venoplasty and stent placement, and 4 were downgraded to type IIa. Sinus stenosis indicated dysfunction of venous drainage and is more often encountered in dural arteriovenous fistula with more aggressive types. Venoplasty ameliorates cortical venous drainage in dural arteriovenous fistulas and serves as a bridge treatment to stereotactic radiosurgery in most cases. © 2017 by American Journal of Neuroradiology.

Iliac Artery-Uretero-Colonic Fistula Presenting as Gastrointestinal Hemorrhage and Hematuria: A Case Report.

Background: The experience with uretero-arterial fistulas has been limited. However, the aggressive treatment of pelvic tumors with surgical resection and radiotherapy, along with liberal use of ureteral catheters, has been attributed to an increase in their incidence. Unless they are promptly diagnosed and treated, uretero-arterial fistulas are associated with considerably high rates of morbidity and mortality. Urologists need maintain a high degree of suspicion for uretero-arterial fistula in high-risk patients. We herein present the clinical course of an iliac artery-uretero-colonic fistula. Case Presentation: A 67-year-old woman with a history of colon cancer who underwent laparoscopic high anterior resection in July 2010. A ureteral stent inserted to right ureteral stricture, which developed as a result of local recurrence of the tumor in September 2010. She had undergone chemoradiotherapy, but the lesion had slowly increased in size. During the replacement of the ureteral stent in April 2016, she immediately experienced bladder tamponade, bloody bowel discharge, and hypotension. Contrast CT revealed a complex fistula between the right distal ureter and the right internal iliac artery. Furthermore, contrast medium flowed into the intestinal tract through the tumor. The patient was therefore diagnosed with internal iliac artery-uretero-colonic fistula. Arteriography revealed a right uretero-internal iliac artery fistula, and the embolization of the right internal iliac artery was performed. The right ureteral stent was removed. Her hematuria and bloody bowel discharge disappeared, but right nephrostomy was performed because she presented with acute pyelonephritis to ureteral obstruction. Conclusion: In the present case, the uretero-arterial fistula was caused by the long use of an indwelling stent, chemoradiotherapy, infection, and an increase in the size of the lesion. When a suspected uretero-arterial fistula is accompanied by bloody bowel discharge, we should consider the possibility of traffic to the intestinal tract.

A vesicovaginal fistula is an abnormal fistulous tract extending between the bladder and the vagina that allows the continuous involuntary discharge of urine into the vaginal vault. In addition, the sequelae from these fistulae have a profound effect on the patients in view of their physical, psychological, and social dimensions. The treatment of vesicovaginal fistula is surgical in most cases and the choice of the repair technique is controversial. We evaluated the benefits of a laparoscopic approach in a patient with vesicovaginal fistulae. Here, we present our first experience using a simplified laparoscopic approach technique to repair vesicovaginal fistulae in our country. A 46-year-old Javanese woman presented with urinary incontinence following an abdominal hysterectomy 3 months earlier and received laparoscopic repair. A cystoscopy was performed to confirm the fistula orifice and a stent was inserted into the fistula tract from her bladder to her vagina. A tamponade was inserted into her vagina up to the vaginal apex, to be able to identify the vagina. She had adhesions; therefore, adhesiolysis was performed using a combination of sharp and blunt dissection to expose the vaginal stump and the superior aspect of her bladder. A simple cystotomy was performed and extended to include the fistulae site, and then the defect was repaired by using a running stitch. A second layer of closure was performed in an imbricating fashion with the same suture. The vagina defect was not closed separately but covered with an omental flap. This procedure takes approximately 2.5 hours; estimated blood loss was minimal and there were no intraoperative complications. She had no recurrent symptoms 6 months after surgery. Our case report concludes that the simplified laparoscopic approach to vesicovaginal fistulae is a viable option for successful repair and that it reduces the size of bladder opening, causes minimal bleeding, and gives successful relief.

Assistance of intraoperative microvascular Doppler in the surgical obliteration of spinal dural arteriovenous fistula: cases description and technical considerations.

Intraoperative microvascular Doppler may be valuable in assisting in the surgical obliteration of dural arteriovenous fistula of the spinal cord. It enables identification, through flow spectrum analysis, of the anatomic components and haemodynamic features of this type of vascular malformation. In two cases, intraoperative microvascular Doppler was used to assist in the surgical obliteration of dural arteriovenous fistula of the spinal cord. The fistulas were identified prior to the dura opening, and for this only minimally invasive surgery was required. Direct recordings of the arterialised draining vein and the nidus of the fistula demonstrated a pathological spectrum caused by the arterial supply and the disturbed venous outflow in which a high-resistance flow pattern and low diastolic flow resembling an arterial-like flow velocity were observed. The fistulas were obliterated by interruption of the draining vein, and Doppler measurements provided information on flow velocity changes in the medullary veins from an arterial to a venous pattern. The absence of any residual flow in the draining vein confirmed successful haemodynamic treatment. Intraoperative microvascular Doppler recording is valuable assistance in surgical closure of spinal arteriovenous fistula.

Traumatic thoracobiliary fistula is a rare but serious complication. A series of thoracobiliary fistulas secondary to penetrating trauma and analysis of trends in management are presented. We retrospectively reviewed all patients with traumatic thoracobiliary fistula, treated from April 2008 to February 2010. There were 5 patients: 4 suffered gunshot wounds and 1 was stabbed. The mean injury severity score was 22. Initial treatment was insertion of a chest tube in all cases. One patient underwent damage-control surgery and hepatic packing, and 3 were managed with laparotomy, a perihepatic closed drain, and suture of the diaphragm. Two patients developed bronchobiliary fistulas and 3 had pleurobiliary fistulas. Diagnostic procedures involved determination of bilirubin in pleural effusion, computed tomography, magnetic resonance cholangiography, hepatobiliary iminodiacetic scans, and endoscopic retrograde cholangiography. Definitive treatment included sphincterotomy and stenting in 4 cases, pulmonary decortication in 5, fistulectomy in 2, hepatic suture in 2, perihepatic closed drain placement in 4, and suture of the diaphragm in 4. Traumatic thoracobiliary fistulas are complex lesions. A multidisciplinary approach is required for a timely and successful outcome. Endoscopic retrograde cholangiography is very useful as the initial procedure to confirm the diagnosis and also for treatment.

Infliximab has been proven to be effective for refractory luminal and fistulizing Crohns disease (CD). We performed this study to demonstrate the efficacy of infliximab in Korean CD patients. Medical records of 40 CD patients who had been treated with infliximab were reviewed retrospectively. Among 40 patients, 11 (27.5%) patients were treated for refractory luminal disease, 14 (35%) for fistulizing disease, and 15 (37.5%) for both types. Clinical response rate was higher in 26 patients with refractory luminal disease (Complete response (CR), 73.1%; Partial response (PR), 23.1%) than in 29 patients with fistulizing disease (CR, 41.4%; PR, 31%) (p=0.024). The clinical response rate tended to be higher in 28 patients with external fistulas (CR, 46.4%; PR, 32.2%) than 4 patients with internal fistulas (PR, 25%; NR, 75%) (p=0.064). Among patients with external fistulas, the response rate of 8 patients with enterocutaneous fistulas (CR, 50%; PR, 12.5%) was not different from 20 patients with perianal fistulas (CR, 45%; PR, 40%). Among 20 patients with perianal fistulas, the response rate of 6 patients with perianal fistulas without a history of operation (CR, 83.3%; PR, 0%) was higher than 14 patients with perianal fistulas resistant to previous surgical treatment (CR, 28.6%; PR, 57.1%) (p=0.044). As for adverse reaction, 7 patients experienced mild infusion reaction, and 2 patients developed serious infection. Infliximab is more effective for refractory luminal disease than for fistulizing disease. In addition, clinical responses to infliximab are different according to subtypes of fistulas. These findings should be considered for the proper use of infliximab.

Anal fistula with foot extension-Treated by kshara sutra (medicated seton) therapy: A rare case report.

PubMed

Ramesh, P Bhat

An 'anal' fistula is a track which communicates anal canal or rectum and usually is in continuity with one or more external openings. Distant communication from rectum is rare. It is a challenging disease because of its recurrence especially, with high level and distant communications. Ksharasutra (medicated seton) therapy is being practiced in India with high success rate (recurrence of 3.33%) in the management of complicated anal fistula. A 56 year old man presented with recurrent boils in the left lower limb at different places from thigh to foot. He underwent repeated incision and drainage at different hospitals. Examination revealed sinus with discharge and multiple scars on left lower limb from thigh up to foot. Suspecting anal fistula, MRI was advised which revealed a long cutaneous fistula from rectum to left lower limb. Patient was treated with Ksharasutra therapy. Within 6 months of treatment whole tract was healed completely. Sushrutha (500BC) was the first to explain the role of surgical excision and use of kshara sutra for the management of anal fistula. Ksharasutra therapy showed least recurrence. Fistula from rectum to foot is of extremely rare variety. Surgical treatment of anal fistula requires hospitalization, regular post-operative care, is associated with a significant risk of recurrence (0.7-26.5%) and a high risk of impaired continence (5-40%). Rectal fistula communicating till foot may be a very rare presentation in proctology practice. Kshara sutra treatment was useful in treating this condition, with minimal surgical intervention with no recurrence. Copyright © 2013 Surgical Associates Ltd. Published by Elsevier Ltd.

While ovarian mature cystic teratomas are benign ovarian germ-cell tumors and the most common type of all ovarian tumors, the formation of fistulas into surrounding organs such as the bladder and the intestinal tract is extremely rare. This report documents a case of ovarian mature cystic teratoma with a rectal fistula, thought to be caused by local inflammation. A pelvic mass was diagnosed as an ovarian mature cystic teratoma of approximately 10 cm in diameter on transvaginal ultrasound and magnetic resonance examinations. Endoscopic examination of the lower gastrointestinal tract to investigate diarrhea revealed an ulcerative lesion with hair in the rectal wall adjacent to the ovarian cyst, and formation of a fistula from the ovarian teratoma into the rectum was suspected. Laparotomy revealed extensive inflammatory adhesions between a left ovarian tumor and the rectum. Left salpingo-oophorectomy and upper anterior resection of the rectum were performed. The final pathological diagnosis was ovarian mature cystic teratoma with no malignant findings, together with severe rectal inflammation and fistula formation with no structural disorders such as diverticulitis of the colon or malignant signs. The formation of fistulas and invasion into the neighboring organs are extremely rare complications for ovarian mature cystic teratomas. The invasion of malignant cells into neighboring organs due to malignant transformation of the tumor is reported as the cause of fistula formation into the neighboring organs. A review of 17 cases including the present case revealed that fistula formation due to malignant transformation comprised only 4 cases (23.5 %), with inflammation as the actual cause in the majority of cases (13 cases, 76.5 %). Although malignancy is the first consideration when fistula formation is observed between ovarian tumors and surrounding organs, in mature cystic teratoma, local inflammation is more likely than malignant transformation.

To correlate the operative findings of patients with fistula-in-ano with preoperative MRI and quantify the information added with MRI. All consecutive fistula-in-ano patients operated between July 2013 and May 2015 were prospectively enrolled. Preoperative MRI was done in every patient. The details of tracts, internal opening and "complex parameters" (additional tract or additional internal opening, horseshoe tract, associated abscess and supralevator extension) found at surgery were compared to the findings determined by MRI. A total of 229 patients (424 tracts) with mean age-49.0 ± 11.3 years were included. M/F 198/31. James hospital classification: Type I 58, II 20, III 49, IV 86 and V 16. The sensitivity and specificity of MRI in diagnosing fistula tracts were 98.8 and 99.7%, respectively, and in identifying internal opening were 97.7 and 98.6%, respectively. MRI added significant information in 46.7% (107/229) patients which was presence of additional tracts in 71 (66.3%), horseshoe tract in 63 (58.8%), supralevator extension in 16 (14.9%), unsuspected abscess in 11 (10.3%) and multiple internal openings in one patient (1%). The proportion of simple/complex fistula (based on history and clinical examination alone) was 32.8/67.2% which changed to 21.4/78.6% after the MRI scan. MRI added significant information about unsuspecting complex parameters which were missed on history and clinical examination in more than one-third (26/75: 34.6%) of simple fistulae and more than half (81/154: 52.5%) of already known complex fistulae. MRI is highly accurate in diagnosing fistula-in-ano and added significant information about unsuspected complex parameters in over one-third (34.6%) of simple and in half (52.5%) of complex fistula-in-ano.

Background: Perianal fistula is a topic both hard to understand and to teach. The key to understanding the treatment options and the likely success is deciphering the exact morphology of the tract(s) and the amount of sphincter involved. Our aim was to explore alternative platforms better to understand complex perianal fistulas through three-dimensional (3D) imaging and reconstruction. Methods: Digital imaging and communications in medicine images of spectral attenuated inversion recovery magnetic resonance imaging (MRI) sequences were imported onto validated open-source segmentation software. A specialist consultant gastrointestinal radiologist performed segmentation of the fistula, internal and external sphincter. Segmented files were exported as stereolithography files. Cura (Ultimaker Cura 3.0.4) was used to prepare the files for printing on an Ultimaker 3 Extended 3D printer. Animations were created in collaboration with Touch Surgery™. Results: Three examples of 3D printed models demonstrating complex perianal fistula were created. The anatomical components are displayed in different colours: red: fistula tract; green: external anal sphincter and levator plate; blue: internal anal sphincter and rectum. One of the models was created to be split in half, to display the internal opening and allow complexity in the intersphincteric space to better evaluated. An animation of MRI fistulography of a trans-sphincteric fistula tract with a cephalad extension in the intersphincteric space was also created. Conclusion: MRI is the reference standard for assessment of perianal fistula, defining anatomy and guiding surgery. However, communication of findings between radiologist and surgeon remains challenging. Feasibility of 3D reconstructions of complex perianal fistula is realized, with the potential to improve surgical planning, communication with patients, and augment training. PMID:29854001

The study aimed to report a primary vaginal stone, an extremely rare entity, without vesicovaginal fistula in a woman with disability. We describe the case of a large primary vaginal calculus in a 22-year-old woman with paraplegia, which, surprisingly, was not diagnosed until she was examined under general anesthesia during a preparation for laparoscopy for an adnexal mass. The stone had not been identified by physical examination with the patient in a recumbent position or by transabdominal ultrasonography and pelvic tomography during the preoperative preparation. Vaginoscopy was not performed because the vagina was completely filled with the mass. As a result of its size and hard consistency, a right-sided episiotomy was performed and a 136-g stone was removed using ring forceps. A vesicovaginal fistula was excluded. There was no evidence of a foreign body or other nidus on the cut section of the stone, and it was determined to be composed of 100% struvite (ammonium magnesium phosphate). Culture of urine obtained via catheter showed Escherichia coli. After the surgical removal of the calculus without complications, a program of intermittent catheterization was started. The follow-up period was uneventful, and the patient was symptom free at 6 months after the operation. We postulate that the calculus formed as a consequence of urinary contamination of the vagina in association with incontinence and prolonged maintenance in a recumbent posture. This report is important because it highlights that, although vaginal stones are very rare, their possibility should be considered in the differential diagnosis of individuals with long-term paraplegia.

Salvage laryngectomy (SL) is associated with high levels of morbidity. Rates of pharyngocutaneous fistulae (PCF) are as high as 35 % in some series. Patients at highest risk of such complications may be candidates for altered surgical management in terms of additional tissue transfer, or delayed tracheoesophageal puncture. This study investigates the relationship between the time from primary radiotherapy (RT) to salvage surgery and the development of PCF. 26 consecutive patients who underwent SL between 2000 and 2010 were identified from our institutional database. Demographic, staging, treatment and complication data were collected. Subgroup analysis was performed using the Student's t test or Mann-Whitney U test for continuous variables and either Chi-squared test or Fisher's Exact test for categorical variables. 26 patients underwent SL between October 2003 and July 2010. Of these, 15 (58 %) developed a PCF. On analysis of the time between pre-operative RT and surgery, a significant difference was seen, with a mean time of 19.5 months in those who developed a PCF versus 47.0 months in those who did not (p = 0.02). Patient characteristics, treatment, and pathology results were comparable between the two groups. There was no significant difference in distribution of the other covariates between the PCF and non-PCF groups. We reported a high rate of PCF and identified an association between PCF and a short time from primary treatment to salvage surgery. Identifying factors associated with higher rates of post-operative morbidity allows surgeons to adapt surgical planning in an attempt to minimize rates of PCF.

Posterior communicating artery (PCoA) aneurysm-cavernous sinus fistulae are an extremely rare complication of head injury . The treatment of PCoA aneurysm-cavernous sinus fistulae has not been well described. A 27-year-old man was admitted with a retroocular bruit and blurred vision of the left eye seven months after a severe head injury. We report the angiographic appearance of a posterior communicating artery (PCoA) aneurysm with a fistula to the cavernous sinus. This injury had been previously misinterpreted to be a PCoA aneurysm by computerized tomographic angiography (CTA). The patient was successfully treated with coils and Onyx of a fistula between the PCoA aneurysm and cavernous sinus.

Management of enterocutaneous fistulas and problem stomas with silicone casting of the abdominal wall defect.

Streza, G A; Laing, B J; Gilsdorf, R B

1977-12-01

Silicone casting of abdominal wall defects around enteric fistulas in six patients and problem stomas in three patients proved to be an effective means of controlling the output of the fistulas, reducing wound care time, and reducing or eliminating parenteral nutrition needs. Outpatient management was possible in seven of the nine patients. It is observed that the wounds healed rapidly with this method of fistula control. Epithelialization occurred more rapidly than expected. This method of management may tend to make the fistulas remain open longer than by other means of care, but the significant increase in patient comfort, the financial savings, and the relative safety warrant continued utilization and observation of this method of management.

Interventional Management of Gastrointestinal Fistulas

Gastrointestinal (GI) fistulas are frequently very serious complications that are associated with high morbidity and mortality. GI fistulas can cause a wide array of pathophysiological effects by allowing abnormal diversion of the GI contents, including digestive fluid, water, electrolytes, and nutrients, from either one intestine to another or from the intestine to the skin. As an alternative to surgery, recent technical advances in interventional radiology and percutaneous techniques have been shown as advantageous to lower the morbidity and mortality rate, and allow for superior accessibility to the fistulous tracts via the use of fistulography. In addition, new interventional management techniques continue to emerge. We describe the clinical and imaging features of GI fistulas and outline the interventional management of GI fistulas.

Fistulas complicating an abdominal aortic aneurysm (AAA) are rare, and fistulas involving the left renal vein are particularly uncommon. We highlight here a fistula between an infrarenal aortic aneurysm and a retroaortic left renal vein, revealed by left flank pain associated with hematuria and acute renal failure. The multislice CT angiography performed in this 68-year-old patient revealed communication and equal enhancement between the aorta and the left gonadic vein, suggesting the presence of a fistula. The three-dimensional VRT reconstructions presented in this case were of great value in the preoperative planning, enabling immediate visualization of this unusual feature.

2014-01-01

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

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

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

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

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

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

Surgical operation in treating obesity and type 2 diabetes is popularizing rapidly in China. Correct prevention and recognition of perioperation-related operative complications is the premise of ensuring surgical safety. Familiar complications of the operation include deep venous thrombosis, pulmonary artery embolism, anastomotic bleeding, anastomotic fistula and marginal ulcer. The prevention of deep venous thrombosis is better than treatment. The concrete measures contain physical prophylaxis (graduated compression stocking and intermittent pneumatic compression leg sleeves) and drug prophylaxis (unfractionated heparin and low molecular heparin), and the treatment is mainly thrombolysis or operative thrombectomy. The treatment of pulmonary artery embolism includes remittance of pulmonary arterial hypertension, anticoagulation, thrombolysis, operative thrombectomy, interventional therapy and extracorporeal membrane oxygenation (ECMO). Hemorrhage is a rarely occurred but relatively serious complication after bariatric surgery. The primary cause of anastomotic bleeding after laparoscopic gastric bypass is incomplete hemostasis or weak laparoscopic repair. The common bleeding site in laparoscopic sleeve gastrectomy is gastric stump and close to partes pylorica, and the bleeding may be induced by malformation and weak repair technique. Patients with hemodynamic instability caused by active bleeding or excessive bleeding should timely received surgical treatment. Anastomotic fistula in gastric bypass can be divided into gastrointestinal anastomotic fistula and jejunum-jejunum anastomotic fistula. The treatment of postoperative anastomotic fistula should vary with each individual, and conservative treatment or operative treatment should be adopted. Anastomotic stenosis is mainly related to the operative techniques. Stenosis after sleeve gastrectomy often occurs in gastric angle, and the treatment methods include balloon dilatation and stent implantation, and surgical treatment should be performed when necessary. Marginal ulcer after gastric bypass is a kind of peptic ulcer occurring close to small intestine mucosa in the junction point of stomach and jejunum. Ulcer will also occur in the vestige stomach after laparoscopic sleeve gastrectomy, and the occurrence site locates mostly in the gastric antrum incisal margin. Preoperative anti-HP (helicobacter pylorus) therapy and postoperative continuous administration of proton pump inhibitor (PPI) for six months is the main means to prevent and treat marginal ulcer. For patients on whom conservative treatment is invalid, endoscopic repair or surgical repair should be considered. Different surgical procedures will generate different related operative complications. Fully understanding and effectively dealing with the complications of various surgical procedures through multidisciplinary cooperation is a guarantee for successful operation.

This study was performed to investigate speech outcomes after three different types of palatoplasty for the same cleft type. The objective of this study was to investigate the surgical techniques that are essential for normal speech on the basis of each surgical characteristic. Thirty-eight consecutive nonsyndromic patients with unilateral complete cleft of the lip, alveolus, and palate were enrolled in this study. Speech outcomes, i.e., nasal emission, velopharyngeal insufficiency, and malarticulation after one-stage pushback (PB), one-stage modified Furlow (MF), or conventional two-stage MF palatoplasty, were evaluated at 4 (before intensive speech therapy) and 8 (after closure of oronasal fistula/unclosed hard palate) years of age. Velopharyngeal insufficiency at 4 (and 8) years of age was present in 5.9% (0.0%), 0.0% (0.0%), and 10.0% (10.0%) of patients who underwent one-stage PB, one-stage MF, or two-stage MF palatoplasty, respectively. No significant differences in velopharyngeal function were found among these three groups at 4 and 8 years of age. Malarticulation at 4 years of age was found in 35.3%, 10.0%, and 63.6% of patients who underwent one-stage PB, one-stage MF, and two-stage MF palatoplasty, respectively. Malarticulation at 4 years of age was significantly related to the presence of a fistula/unclosed hard palate (P<0.01). One-stage MF palatoplasty that was not associated with postoperative oronasal fistula (ONF) showed significantly better results than two-stage MF (P<0.01). Although the incidences of malarticulation at 8 years of age were decreased in each group compared to at 4 years of age, the incidence was still high in patients treated with two-stage MF (45.5%). On the whole, there was a significant correlation between ONF/unclosed hard palate at 4 years of age and malarticulation at 8 years of age (P<0.05). Appropriate muscle sling formation can compensate for a lack of retropositioning of the palate for adequate velopharyngeal closure. Early closure of the whole palate and the absence of a palatal fistula were confirmed to be essential for normal speech. To avoid fistula formation, multilayer repair of the whole palate may be critical. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

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

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. PMID:19096247

SUMMARY The pectoralis major myocutaneous flap (PMMF) is a safe and versatile flap used widely for head and neck cancer reconstructions, but one of the major and most feared complications is oro- or pharyngocutaneous fistula. Herein, we attempt to establish risk factors for fistula formation in reconstructions of mucosal defects in the head and neck using PMMF through retrospective analysis of PMMF performed during 3 years at a single institution, with a total of 84 procedures. There were 69 men and 15 women, with a mean age of 59.5 years. There were 15 cases of partial flap loss, two total flap losses and 31 fistulas. The independent risk factors for fistula formation were preoperative serum hemoglobin < 13 g/dl, preoperative serum albumin < 3.4 g/dl and hypopharynx reconstruction. The PMMF is still a very useful flap and this is the first multivariate analysis analysing risk factors for fistula formation. These findings are helpful in selecting patients with elevated risk of fistula formation, and therefore preventive measures can be undertaken to avoid potentially serious complications.

Esophagojejunal fistula is a serious complication after total gastrectomy in gastric cancer patients. This study describes the successful conservative management in 3 gastric cancer patients with esophagojejunal fistula after total gastrectomy using total enteral nutrition. Between January 2004 to December 2008, 588 consecutive patients with a proven diagnosis of gastric cancer were taken to the operation room to try a curative treatment. Of these, 173 underwent total gastrectomy, 9 of them had esophagojejunal fistula (5.2%). In three selected patients a trans-anastomotic naso-enteral feeding tube was placed under fluoroscopic vision when the fistula was clinically detected and a complete polymeric enteral formula was used. The complete closing of the esophagojejunal fistula was obtained in day 8, 14 and 25 respectively. In some selected cases it is possible to make a successful enteral nutrition using a feeding tube distal to the leak area inserted with the help of fluoroscopic vision. The specialized management of a gastric surgery unit and nutritional therapy unit are highlighted.

Pancreatic fistula( PF) is a challenging postoperative complication. We report a case of PF following gastrectomy successfully treated using intravenous coagulation factor XIII( FXIII).A 78-year-old man with early gastric cancer underwent total gastrectomy with Roux-en-Y reconstruction. PF developed postoperatively, following which, leakage from the duodenal stump was observed. Percutaneous drainage and re-operative surgery were performed. A somatostatin analogue, antibiotic drugs, and gabexate mesilate were administrated along with nutritional support. The pancreatic and duodenal fistula had been producing duodenal juice for over 30 days since the re-operative surgery. As suspected, reduced FXIII activity was confirmed in the patient. After administering FXIII for 5 days, the amount of duodenal juice from the fistula markedly reduced, and the fistula closed immediately afterwards. The results of our study suggest that administration of FXIII could be a reasonable and effective treatment for patients with pancreatic or/and enterocutaneous fistula who are resistant to standard treatments.

Non perianal fistulas in Crohn's disease and short bowel syndrome: what we can do?

2009-01-01

Crohn's disease (CD) is a lifelong disease arising from an interaction between genetic and environmental factors, but seen predominantly in the developed countries of the world. The precise etiology is unknown and therefore a causal treatment is not yet available. Fistulating Crohn's disease includes fistulas arising in the perianal area, together with those communicating between the intestine and other organs or the abdominal wall. Non perianal fistulas include fistulas communicating with other viscera (urinary bladder, vagina), loops of intestine (enteroenteral fistulas) or the abdominal wall (enterocutaneus fistulas). The diagnostic approach is a crucial aspect in the management of fistulating CD as the findings influence the therapeutic strategy. Short bowel syndrome caused by extensive bowel resection should be initially treated with nutritional support and can caused serious treatment and reevaluating problems. We review this uncommon manifestation in a high risk patient after multiple operations and severely shortened bowel and also with non perianal fistulating CD.

Intra-abdominal pedicled rectus abdominis muscle flap for treatment of high-output enterocutaneous fistulae: case reports and review of literature.

Despite advances in nutritional supplementation, sepsis management, percutaneous drainage and surgical technique, enterocutaneous fistulae remain a considerable source of morbidity and mortality. Use of adjunctive modalities including negative pressure wound therapy and fibrin glue have been shown to improve the rapidity of fistula closure; however, the overall rate of closure remains poor. The challenge of managing chronic, high-output proximal enterocutaneous fistulae can be successfully achieved with appropriate medical management and intra-abdominal placement of pedicled rectus abdominis muscle flaps. We report two cases of recalcitrant high output enterocutaneous fistulae that were treated successfully with pedicled intra-abdominal rectus muscle flaps. Indications for pedicled intra-abdominal rectus muscle flaps include persistent patency despite a reasonable trial of non-operative intervention, failure of traditional operative interventions (serosal patch, Graham patch), and persistent electrolyte and nutritional abnormalities in the setting of a high-output fistula.

2017-10-01

Eastern Sudan has high prevalence of female circumcision and child marriage constituting a risk for developing obstetric fistula. Few studies have examined gender roles' relation with obstetric fistula in Sudan. To explore the associated power-relations that may put women at increased risk for developing obstetric fistula, we conducted nine interviews with women living with obstetric fistula in Kassala in eastern Sudan. Using a Foucauldian discourse analysis, we identified three discourses: powerlessness, normalization, and covert resistance. Existing power-relations between the women and other societal members revealed their internalization of social norms as absolute truth, and influenced their status and decision-making power in regard to circumcision, early marriage, and other transformative decisions as well as women's general behaviors. The women showed subtle resistance to these norms and the harassment they encountered because of their fistula. These findings suggest that a more in-depth contextual assessment could benefit future maternal health interventions.

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

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.

To describe the clinical entity and therapeutic challenges of bisphosphonate-related osteonecrosis of the jaws (BRONJ). The use of vascularized bone grafts for reconstruction of the mandible in extensive BRONJ is proposed. Multi-institutional retrospective review. Patients undergoing mandible reconstruction with vascularized bone grafts after segmental mandible resection for BRONJ were evaluated. Mandible reconstruction was only performed on patients with intractable pain, fistulae, or pathologic fracture and after failure of comprehensive conservative therapy. No patients had a history of primary or metastatic head and neck malignancy or radiation therapy. Bone union was established with follow-up radiography. Eleven patients met inclusion criteria. Mean patient age was 61.3 years. Median follow-up was 13.9 months. All patients had undergone therapy with bisphosphonates and had no other identifiable cause of mandible osteonecrosis. Preoperatively, pathologic mandible fractures were present in 73% of patients, and 36% had orocutaneous fistulae. Fibula osteocutaneous flaps were used in all cases with no failures. In all patients, bony union was demonstrated clinically and radiographically. Postoperative wound complications occurred in 36% of patients but were all treated successfully with conservative therapy. There was no BRONJ recurrence within the study follow-up period. Osteonecrosis is a significant complication of bisphosphonate therapy, and current literature does not support vascularized reconstruction. We demonstrate that vascularized bone graft reconstruction with the fibula free flap offers a high success rate of bony union and fistula closure and should be offered to selected patients with advanced cases of BRONJ.

Percutaneous transluminal angioplasty (PTA) and fistula reconstruction surgery are therapeutic options for vascular access occlusion in hemodialysis patients. However, owing to its convenience, PTA has gradually become the preferred therapeutic option for fistula stenosis or occlusion. This study investigated the effects of the two therapeutic methods on the vascular access maintenance duration (number of days) and maintenance costs of fistula in dialysis patients from different dialysis units. In this study, 544 hemodialysis patients from 2 dialysis units in a teaching hospital in the southern area of Taiwan were included in the analysis of the frequency of PTA or revascularization surgery and the use of related medical resources by conducting a retrospective chart review. The frequency of PTA in the patients undergoing long-term hemodialysis was not significantly associated with their demographic characteristics. The efficacy of PTA has declined with shorter maintenance duration with increasing PTA frequency. The cost profile of PTA was more expensive than that of fistula revascularization surgery. In this study, PTA was found to be just a temporary solution for fistula thrombosis, whereas fistula reconstruction surgery is inexpensive and improves survival time. Therefore, dialysis units should establish an appropriate standard of care to avoid over-reliance on PTA in order to reduce the fistula failure rate, improve the dialysis efficacy, and reduce the psychological stress in patients, as well as to reduce the maintenance costs and rationalize the medical expenses.

To evaluate 2- and 12-month outcomes after ligation of the intersphincteric fistula tract (LIFT) in Crohn's disease (CD). Surgical approaches to perianal fistulas in CD are frequently ineffective and hampered by concerns over adequate wound healing and sphincter injury. The efficacy of LIFT in CD patients is unknown. Consecutive cases of CD patients with transsphincteric fistulas were prospectively analyzed. Fistula healing and 2 validated quality-of-life indices were assessed. Fifteen CD patients (9 women; mean age = 34.8 years) were identified. Location of the fistula was lateral (n = 10; 67%) or midline (n = 5; 33%). LIFT site healing was seen in 9 patients (60%) at 2-month follow-up. No patient developed fecal incontinence. LIFT site healing was seen in 8 of the 12 patients (67%) with complete 12-month follow-up. Significant factors for long-term LIFT site healing were lateral versus midline location (P = 0.02) and longer mean fistula length (P = 0.02). Patients who had successful operations significantly improved both their mean Wexner Perianal Crohn's Disease Activity Index and McMaster Perianal Crohn's Disease Activity Index quality-of-life scores at 2-month follow-up (14.0-3.8, P = 0.001, and 10.4-1.8, P = 0.0001, respectively). CD-associated anal fistulas may be treated with LIFT. This surgical procedure is a safe, outpatient procedure that minimizes both perianal wound creation and sphincter injury.

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

The aims of the cleft palate repair techniques are to reduce the velopharyngeal insufficiency risk and oronasal fistula development to minimal levels without affecting the maxillofacial development. In this article, we present a retrospective study comparing the conventional palatoplasty techniques with the new technique of rotation palatoplasty for the risk of development of oronasal fistula. Of the 100 patients who were operated on because of cleft palate between the years 2002 and 2008, 12 patients had Furlow palatoplasty, and 88 patients received the Veau-Wardill-Kilner (V-Y pushback) operation (group C). A total of 67 patients who were operated on between 2008 and 2011 had rotation palatoplasty (group R). One hundred patients were men, and 67 were women. Among all the patient groups, 22.8% were classified as Veau 1, 24.6% were classified as Veau 2, 37.1% were classified as Veau 3, and 15.6% were classified as Veau 4. The rate of fistula was found to be 17.7% in all patients. Fistula development was found in 6% of the patients in group R (4/67) and in 18% of the patients in group C (18/100). The difference between group R and group C regarding the number of patients who developed fistula was statistically significant (P = 0.011). The Veau classification of the cleft palate affects the risk of fistula development, and the risk for fistula after rotation palatoplasty is lower than that associated with the V-Y pushback technique.

Omphalomesenteric fistula is a complete persistence of the omphalomesenteric duct communicating between the umbilicus and the intestine. The presence of intestinal contents suggests the diagnosis in its typical form. We report a case of omphalomesenteric fistula in a 3-year-old boy to show that intestinal parasitic infection associated with ascariasis expulsion through the umbilicus can be the incidental finding of the omphalomesenteric fistula. This case needs no paraclinical investigation and treatment consists in partial transumbilical resection followed by umbilicus restitution. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

The authors present the case of a 3-year-old girl with a history of complicated surgery for removing a third branchial cleft fistula. An endoscopic approach using N-butyl-2-acrylate and metacrilosisolfolane glue (GLUBRAN 2) to seal the fistula was performed. The clinical and radiological 6-year follow-up confirmed the absence of the fistulous orifice and the persistence of scar due to previous open-neck surgical procedures. endoscopic Glubran 2 sealing has been an effective treatment procedure for branchial fistula.

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

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

A man in his 30s, who had undergone retrocolic Billroth II reconstruction for perforated duodenal ulcer, presented with watery diarrhea for 2 years and suspected fatty liver. He was referred to our hospital for management of chronic diarrhea, weight loss, hepatopathy and hypoalbuminemia. Initial upper and lower gastrointestinal endoscopies were negative. Since a small bowel lesion was suspected, peroral single-balloon enteroscopy was performed, which identified feces-like residue near the Billroth II anastomotic site and a connection to the colon separate from the afferent and efferent loops. Transanal single-balloon enteroscopy identified a fistula between the gastrojejunal anastomosis and transverse colon, with the scope reaching the stomach transanally. Barium enema confirmed flow of contrast medium from the transverse colon through the fistula to the anastomotic site, allowing the diagnosis of gastrojejunocolic fistula. Liver biopsy showed relatively severe steatohepatitis (Brunt's classification: stage 2-3, grade 3). Resection of the anastomotic site and partial transverse colectomy were performed to remove the fistula, followed by Roux-en-Y reconstruction. Postoperatively, watery diarrhea resolved and the stools became normal. Hepatopathy and hypoproteinemia improved. One year later, liver biopsy showed marked improvement of steatosis. This case demonstrated marked improvement of both diarrhea/nutritional status and steatohepatitis after treatment of gastrojejunocolic fistula, suggesting that the fistula caused non-alcoholic steatohepatitis.

The present study was designed to evaluate the effects of guided treatment of patients with an enterocutaneous fistula and to evaluate the effect of prolonged period of convalescence on outcome. All consecutive patients with an enterocutaneous fistula treated between 2006 and 2010 were included in this study. Patient information was gathered prospectively. Treatment of patients focused on sepsis control, optimization of nutritional status, wound care, establishing the anatomy of the fistula, timing of surgery, and surgical principles. Outcome included spontaneous and surgical closure, mortality, and postoperative recurrence. The relationship between period of convalescence and recurrence rate was determined by combining the present prospective cohort with a historical cohort from our group. Between 2006 and 2010, 79 patients underwent focused treatment for enterocutaneous fistula. Cox regression analysis showed that period of convalescence related significantly with recurrence of the fistula (hazard ratio 0.99; 95 % confidence interval 0.98-0.999; p = 0.04). Spontaneous closure occurred in 23 (29 %) patients after a median period of convalescence of 39 (range 7-163) days. Forty-nine patients underwent operative repair after median period of 101 (range 7-374) days and achieved closure in 47 (96 %). Overall, eight patients (10 %) died. Prolonging period of convalescence for patients with enterocutaneous fistulas improves spontaneous closure and reduces recurrence rate.

Lateral congenital anomalies of the pharyngeal apparatus: part III. cadaveric representation of the course of second and third cleft and pouch fistulas.

"Stepladder" surgery for fistula from second or third pharyngeal cleft and pouch is "blind." Neither intraoperative methylene blue injection and probing nor preoperative imaging (fistulogram ultrasound, computed tomography, magnetic resonance imaging) reveal three-dimensional anatomic relations of fistulas. This article describes the most common second and third fistula courses and demonstrates representation of their tracts with wires in human cadavers. A second cleft and pouch fistula, at its external opening, pierces superficial cervical fascia (and platysma), then investing cervical fascia, and travels under the sternocleidomastoid muscle, superficial to the sternohyoid and anterior belly of omohyoid. It ascends along the carotid sheath, and at the upper border of the thyroid cartilage it pierces the pretracheal fascia. Characteristically, it courses between the carotid bifurcation and over the hypoglossal nerve. After passing beneath the posterior belly of the digastric muscle and the stylohyoid, it hooks around both glossopharyngeal nerve and stylopharyngeus muscle. The fistula reaches the pharynx below the superior constrictor muscle. The course of a third cleft and pouch fistula is similar until it has pierced pretracheal fascia; then it passes over the hypoglossal nerve and behind the internal carotid, finally descending parallel to the superior laryngeal nerve, reaching the thyrohyoid membrane cranial to the nerve.

Women living with obstetric fistula often live in poverty and in remote areas far from hospitals offering surgical repair. These women and their families face a range of costs while accessing fistula repair, some of which include: management of their condition, lost productivity and time, and transport to facilities. This study explores, through women's, communities', and providers' perspectives, the financial, transport, and opportunity cost barriers and enabling factors for seeking repair services. A qualitative approach was applied in Kano and Ebonyi in Nigeria and Hoima and Masaka in Uganda. Between June and December 2015, the study team conducted in-depth interviews (IDIs) with women affected by fistula (n = 52) - including those awaiting repair, living with fistula, and after repair, and their spouses and other family members (n = 17), along with health service providers involved in fistula repair and counseling (n = 38). Focus group discussions (FGDs) with male and female community stakeholders (n = 8) and post-repair clients (n = 6) were also conducted. Women's experiences indicate the obstetric fistula results in a combined set of costs associated with delivery, repair, transportation, lost income, and companion expenses that are often limiting. Medical and non-medical ancillary costs such as food, medications, and water are not borne evenly among all fistula care centers or camps due to funding shortages. In Uganda, experienced transport costs indicate that women spend Ugandan Shilling (UGX) 10,000 to 90,000 (US$3.00-US$25.00) for two people for a single trip to a camp (client and her caregiver), while Nigerian women (Kano) spent Naira 250 to 2000 (US$0.80-US$6.41) for transportation. Factors that influence women's and families' ability to cover costs of fistula care access include education and vocational skills, community savings mechanisms, available resources in repair centers, client counseling, and subsidized care and transportation. The concentration of women in poverty and the perceived and actual out of pocket costs associated with fistula repair speak to an inability to prioritize accessing fistula treatment over household expenditures. Findings recommend innovative approaches to financial assistance, transport, information of the available repair centers, rehabilitation, and reintegration in overcoming cost barriers.

An oro-antral communication is an unnatural opening between the oral cavity and maxillary sinus. When it fails to close spontaneously, it remains patent and is epithelialized to develop into an oro-antral fistula. Various surgical and non-surgical techniques have been used for treating the condition. Surgical procedures include flaps, grafts and other techniques like re-implantation of third molars. Non-surgical techniques include allogenic materials and xenografts. To assess the effectiveness and safety of various interventions for the treatment of oro-antral communications and fistulae due to dental procedures. We searched the Cochrane Oral Health Group's Trials Register (whole database, to 3 July 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2015, Issue 6), MEDLINE via OVID (1946 to 3 July 2015), EMBASE via OVID (1980 to 3 July 2015), US National Institutes of Health Trials Registry (http://clinicaltrials.gov) (whole database, to 3 July 2015) and the World Health Organization (WHO) International Clinical Trials Registry Platform (http://www.who.int/ictrp/en/) (whole database, to 3 July 2015). We also searched the reference lists of included and excluded trials for any randomised controlled trials (RCTs). We included RCTs evaluating any intervention for treating oro-antral communications or oro-antral fistulae due to dental procedures. We excluded quasi-RCTs and cross-over trials. We excluded studies on participants who had oro-antral communications, fistulae or both related to Caldwell-Luc procedure or surgical excision of tumours. Two review authors independently selected trials. Two review authors assessed trial risk of bias and extracted data independently. We estimated risk ratios (RR) for dichotomous data, with 95% confidence intervals (CI). We assessed the overall quality of the evidence using the GRADE approach. We included only one study in this review, which compared two surgical interventions: pedicled buccal fat pad flap and buccal flap for the treatment of oro-antral communications. The study involved 20 participants. The risk of bias was unclear. The relevant outcome reported in this trial was successful (complete) closure of oro-antral communication.The quality of the evidence for the primary outcome was very low. The study did not find evidence of a difference between interventions for the successful (complete) closure of an oro-antral communication (RR 1.00, 95% Cl 0.83 to 1.20) one month after the surgery. All oro-antral communications in both groups were successfully closed so there were no adverse effects due to treatment failure.We did not find trials evaluating any other intervention for treating oro-antral communications or fistulae due to dental procedures. We found very low quality evidence from a single small study that compared pedicled buccal fat pad and buccal flap. The evidence was insufficient to judge whether there is a difference in the effectiveness of these interventions as all oro-antral communications in the study were successfully closed by one month after surgery. Large, well-conducted RCTs investigating different interventions for the treatment of oro-antral communications and fistulae caused by dental procedures are needed to inform clinical practice.

Fistula-in-ano is a common medical problem affecting thousands of patients annually. In the past, the options for treatment of fistula-in-ano were limited to fistulotomy and/or seton placement. Current treatment options also include muscle-sparing techniques such as a dermal island flap, endorectal advancement flap, fibrin sealent injection, anal fistula plug, and most recently ligation of the intersphincteric fistula tract (procedure). This study seeks to evaluate types and time trends for treatment of fistula-in-ano. A retrospective review from 1975 to 2009 was performed. Data were collected and sorted into 5-year increments for type and time trends of treatment. Fistulotomy and partial fistulotomy were grouped as cutting procedures. Seton placement, fibrin sealant, dermal flap, endorectal flap, and fistula plug were grouped as noncutting procedures. Statistical analysis was performed for each time period to determine trends. With institutional review board approval, the records of 2,267 fistula operations available for analysis were included. Most of the patients were men (74 vs. 26%). Cutting procedures comprised 66.6% (n = 1510) of all procedures. Noncutting procedures were utilized in 33.4% (n = 757), including Seton placement alone 370 (16.3%), fibrin sealant 168 (7.4%), dermal or endorectal flap 147 (6.5%), and fistula plug 72 (3.2%). The distribution of operations grouped in 5-year intervals is as follows: 1975-1979, 78 cutting and one noncutting; 1980-1984, 170 cutting and 10 noncutting; 1985-1989, 54 cutting and five noncutting; 1990-1994, 37 cutting and six noncutting; 1995-1999, 367 cutting and 167 noncutting; 2000-2004, 514 cutting and 283 noncutting; 2005-2009, 290 cutting and 285 noncutting. The percentage of cutting and noncutting procedures significantly differed over time, with cutting procedures decreasing and noncutting procedures increasing proportionally (χ(2) linear-by-linear association, p < 0.05). Fistula-in-ano remains a common complex disease process. Its treatment has evolved to include a variety of noncutting techniques in addition to traditional fistulotomy. With the advent of more sphincter-sparing techniques, the number of patients undergoing fistulotomy should continue to decrease over time. Surgeons should become familiar with various surgical techniques so the treatment can be tailored to the patient.

A good digital examination is usually sufficient for the diagnosis and the treatment planning of anal fistulae. Cross-sectional imaging techniques, however, can accurately identify deep abscesses and characterize complex fistulae. MRI is well suited for this examination, with almost no motion artifact, excellent contrast between muscles and fatty spaces, and multiplanar acquisition. A fistula starts from an internal opening in the digestive tube and can end in an abscess cavity or open at the skin at an external opening. The cryptoglandular anal fistulae (fistula-in-ano) are non-specific in origin and are usually simple, whereas specific fistulae are due to many diseases such as Crohn's disease, tuberculosis, trauma, radiation, colloid carcinoma, hidradenitis suppurative, actinomycosis or lymphoma and are often complex. MRI appears useful in the cases with recurrent fistulae, Crohn's disease, when the secondary orifice is atypically placed, during a multistep treatment for complex fistulae, or when an anal stenosis forbids a clinical or ultrasound examination. A good knowledge of the perineum anatomy is required for analysing the fistula tracts. The muscle planes separate fatty spaces which have an important role in the spread of the disease: sub-mucosal space, marginal space, intersphincteric space, postanal space of Courtney, supralevator space, and the two ischioanal spaces on both sides of the anal canal. The anal canal is surrounded by the ring-like internal sphincter, which continues the internal muscularis propria of the rectum, and the external sphincter, which is intermingled with the puborectalis muscle. We perform our MRI examination with an external phased array coil, and we place a cannula to identify the anal canal. The T2W sequences give the more interesting information, but the sequences with fat-suppression and gadolinium chelate injection are also very useful. The MRI examination allows the analysis of: 1) the location of the fistula tracts according to Park's classification, 2) the location of the internal opening, 3) the locations of the external opening(s), 4) the location of deep abscesses, 5) the long distance extensions, 6) the state of the ano-rectal wall and the perirectal spaces, 6) the damages of the anal sphincter.

Overcoming phase 1 delays: the critical component of obstetric fistula prevention programs in resource-poor countries

PubMed Central

2012-01-01

Background An obstetric fistula is a traumatic childbirth injury that occurs when labor is obstructed and delivery is delayed. Prolonged obstructed labor leads to the destruction of the tissues that normally separate the bladder from the vagina and creates a passageway (fistula) through which urine leaks continuously. Women with a fistula become social outcasts. Universal high-quality maternity care has eliminated the obstetric fistula in wealthy countries, but millions of women in resource-poor nations still experience prolonged labor and tens of thousands of new fistula sufferers are added to the millions of pre-existing cases each year. This article discusses fistula prevention in developing countries, focusing on the factors which delay treatment of prolonged labor. Discussion Obstetric fistulas can be prevented through contraception, avoiding obstructed labor, or improving outcomes for women who develop obstructed labor. Contraception is of little use to women who are already pregnant and there is no reliable screening test to predict obstruction in advance of labor. Improving the outcome of obstructed labor depends on prompt diagnosis and timely intervention (usually by cesarean section). Because obstetric fistulas are caused by tissue compression, the time interval from obstruction to delivery is critical. This time interval is often extended by delays in deciding to seek care, delays in arriving at a hospital, and delays in accessing treatment after arrival. Communities can reasonably demand that governments and healthcare institutions improve the second (transportation) and third (treatment) phases of delay. Initial delays in seeking hospital care are caused by failure to recognize that labor is prolonged, confusion concerning what should be done (often the result of competing therapeutic pathways), lack of women’s agency, unfamiliarity with and fear of hospitals and the treatments they offer (especially surgery), and economic constraints on access to care. Summary Women in resource-poor countries will use institutional obstetric care when the services provided are valued more than the competing choices offered by a pluralistic medical system.

Severe post-operative complications after pancreaticoduodenectomy (PD) are largely due to pancreatic fistula onset. The occlusion of the main pancreatic duct using synthetic glue may prevent these complications. Aim of this study is to describe this technique and to report short- and long-term results as well as the post-operative endocrine and exocrine insufficiency. Two hundred and four patients who underwent PD with occlusion of the main pancreatic duct in a period of 15 years were retrospectively analyzed. Post-operative complications and their management were the main aim of the study with particular focus on pancreatic fistula incidence and its treatment. At 1-year follow-up endocrine and exocrine functions were analyzed. We observed a 54 % pancreatic fistula incidence, most of which (77/204 patients) were a grade A fistula with little change in medical management. Twenty-eight patients developed a grade B fistula while only 2 % of patients (5/204) developed a grade C fistula. Nine patients required re-operation, 5 of whom had a post-operative grade C fistula. Post-operative mortality was 3.4 %. At 1-year follow-up, 31 % of patients developed a post-operative diabetes while exocrine insufficiency was encountered in 88 % of patients. The occlusion of the main pancreatic duct after PD can be considered a relatively safe and easy-to-perform procedure. It should be reserved to selected patients, especially in case of soft pancreatic texture and small pancreatic duct and in elderly patients with comorbidities, in whom pancreatic fistula-related complications could be life threatening.

Intraductal papillary mucinous neoplasms (IPMNs) occasionally involve formation of fistulas with other adjacent organs. Pancreatobiliary fistulas associated with IPMNs are rare, but affected patients often develop obstructive jaundice and cholangitis. A 79-year-old man was referred to our hospital for evaluation of abnormal biliary enzymes. Contrast-enhanced computed tomography and endoscopic retrograde cholangiopancreatography demonstrated multiple cystic lesions with septa in the pancreatic head and fistulas between the cystic lesions and common bile duct. The clinical diagnosis was pancreatobiliary fistula associated with a mixed-type IPMN and accompanying obstructive jaundice. The patient underwent subtotal stomach-preserving pancreaticoduodenectomy. The resected specimen showed fistulas between the cystic lesions and common bile duct. Histopathological examination showed that the main and branch ducts of the pancreatic head were dilated and filled with mucus. The epithelia of the pancreatic ducts revealed papillary proliferation and an invasive adenocarcinoma arising from an intraductal neoplasm. Immunohistochemistry examination showed CDX2- and MUC2-positive reactions. The final diagnosis was an intraductal papillary mucinous carcinoma of the intestinal-type. The patient remained disease-free for 9 months postoperatively. The causes of death in patients who have pancreatobiliary fistulas associated with IPMNs without resection are cholangitis or hepatic insufficiency. Nonoperative treatment is limited for cases with obstructive jaundice. It is necessary to prevent obstructive jaundice and cholangitis due to a large quantity of mucinous material. Surgical resection should be considered, if possible, in patients with pancreatobiliary fistulas associated with IPMNs. A better prognosis is expected with prevention of obstructive jaundice or cholangitis. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

Magnetic resonance imaging (MRI) is considered the imaging standard for diagnosis and characterization of perianal complications associated with Crohn disease in children and adults. To define MRI criteria that could act as potential predictors of treatment response in fistulizing Crohn disease in children, in order to guide more informed study interpretation. We performed a retrospective database query to identify all children and young adults with Crohn disease who underwent serial MRI studies for assessment of perianal symptoms between 2003 and 2010. We examined imaging features of perianal disease including fistula number, type and length, presence and size of associated abscess, and disease response/progression on follow-up MRI. We reviewed imaging studies and electronic medical records. Statistical analysis, including logistic regression, was performed to associate MR imaging features with treatment response and disease progression. We included 36 patients (22 male, 14 female; age range 8-21 years). Of these, 32 had a second MRI exam and 4 had clinical evidence of complete response, obviating the need for repeat imaging. Of the parameters analyzed, presence of abscess, type of fistula according to the Parks classification, and multiplicity were not predictors of treatment outcome. Maximum length of the dominant fistula and aggregate fistula length in the case of multiple fistulae were the best predictors of treatment outcome. Maximum fistula length <2.5 cm was a predictor of treatment response, while aggregate fistula length ≥2.5 cm was a predictor of disease progression. Perianal fistula length is an important imaging feature to assess on MRI of fistulizing Crohn disease.

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.

Ten patients with giant intradural spinal arteriovenous fistulas (perimedullary Types II and III) were treated with embolization alone (three patients) or in combination with surgery (seven patients). Their ages at the time of treatment ranged from 2 to 40 years, with a mean of 19.5 years. The indications for treatment included progressive myelopathy in five patients, spinal subarachnoid hemorrhage in four, and acute paraplegia in one. Associated conditions included Rendu-Osler-Weber syndrome in two patients, and Cobb's syndrome in two patients. In one patient, the cause of the fistula may have been related to epidural anesthesia traumatizing a low tethered cord. Angiographically, the fistulas were subclassified in three groups: a single-hole fistula supplied by a single feeding medullary artery (three patients); a single-hole fistula supplied by multiple medullary arteries (three patients); and multiple separate fistulas supplied by multiple medullary arteries (four patients). Eight patients were classified as perimedullary Type III and two as perimedullary Type II. Embolic agents were delivered from transarterial routes in 14 procedures and transvenous routes in 2 procedures. A total of 16 embolizations and 8 operations were performed in 10 patients. Seven patients were cured of their fistula (as demonstrated by angiography), two patients had 5% residual filling and are scheduled for future therapy. One refused a follow-up angiographic examination. Complications related to embolization included rupture of the anterior spinal artery by a detachable balloon, resulting in transient worsening of paraplegia with recovery to baseline. Transient worsening of symptoms after surgery was common, but all patients returned to baseline or better. Dramatic improvement was observed in four patients.(ABSTRACT TRUNCATED AT 250 WORDS)

To summarize the clinical characteristics and therapeutic experience of A/H5N1 infected patient with intractable bronchopleural fistula. The data of a patient with A/H5N1 infection complicated with bronchopleural fistula was collected and analyzed. A 44-year-old woman with pneuminian was diagnosed as A/H5N1 infection by reverse-transcription polymerase chain reaction (RT-PCR) in laboratory from the sample of secretion of respiratory tracts. She had exposed to sick or dead poultry 3 days before development of illness. She developed acute respiratory distress syndrome 7 days after onset of sickness. After comprehensive management with antiviral agents, antibiotics, convalescent serum and invasive ventilation, her clinical condition improved and turned to stable. However, 16 days after onset of illness, her clinical situation deteriorated due to ventilator-associated pneumonia, bilateral pneumothorax and persistent right bronchopleural fistula. After partly failure of beside assist thoracoscopy to fix the pleural fistula, transbronchoscopic bronchial occlusion by autoblood was explored and the air leakage stopped soon after occlusion. Three days after the autoblood clot was expectorated out and air leak recurred. Then, bronchopleural fistula on the surface of visceral pleura was successfully blocked by biogel and OB gel through pleural cavity by fibrobronchoscopy. The patient was discharged from the hospital 99 days after onset of illness (at the 94th hospital day). Bronchopleural fistula was an intractable complication for patient with A/H5N1 infection. Occlusion operation by biogel and OB gel through bronchoscopy might be an alternative choice for fixing the bronchopleural fistula.

Background and objectives: Conversion from central venous catheters to a graft or a fistula is associated with lower mortality risk in long-term hemodialysis (HD) patients; however, a similar association with hospitalization risk remains to be elucidated. Design, setting, participants, & measurements: We conducted a prospective observational study all maintenance in-center HD patients who were treated in Fresenius Medical Care, North America legacy facilities; were alive on January 1, 2007; and had baseline laboratory data from December 2006. Access conversion (particularly from a catheter to a fistula or a graft) during the 4-month period from January 1 through April 30, 2007, was linked using Cox models to hospitalization risk during the succeeding 1-year follow-up period (until April 30, 2008). Results: The cohort (N = 79,545) on January 1, 2007 had 43% fistulas, 29% catheters, and 27% grafts. By April 30, 2007, 70,852 patients were still on HD, and among 19,792 catheters initially, only 10.3% (2045 patients) converted to either a graft or a fistula. With catheters as reference, patients who converted to grafts/fistulas had similar adjusted hazard ratios (0.69) as patients on fistulas (0.71), while patients with fistulas/grafts who converted to catheters did worse (1.22), all P < 0.0001. Conclusions: Catheters remain associated with the greatest hospitalization risk. Conversion from a catheter to either graft or fistula had significantly lower hospitalization risk relative to keeping the catheter. Prospective studies are needed to determine whether programs that reduce catheters will decrease hospitalization risk in HD patients. PMID:20884778

Different types of vaginal fistulas is a relatively uncommon condition in the Western world but very frequent in developing countries. In the past, conventional vaginography was the radiological examination of choice for exploring this condition. CT and MRI are now both used for this purpose. Our objective was to test the feasibility and to explore the potential role of a new CT imaging technique implementing vaginal introitus obstruction and opacification of the vagina with iodine contrast agent, to show patency of a fistula. We describe the technical protocol of CT-vaginography as performed in Geneva University Hospitals, including vaginal catheterization with a Foley catheter and obstruction of the introitus by inflating the balloon of the catheter. We also report three cases of patients with suspected vaginal fistula who underwent CT-vaginography. The examinations were technically successful. In one patient, it revealed the presence of fistulous pathways from the vaginal fornix along the bilateral infected surgical prostheses. In a second patient, it showed a fistula between the vagina and the necrotic cavity of a recurrent cervical cancer. In a third patient, it proved the absence of a suspected vaginal fistula. CT-vaginography is a technically feasible CT protocol that provides anatomical and functional information on clinically suspected vaginal fistulas. Advances in knowledge: After the abandon of conventional vaginography in the era of transaxial imaging, the current modalities of imaging vaginal fistulas provide excellent anatomical detail but less functional information concerning the permeability of a vaginal fistulous pathway. We propose the use of CT-vaginography, a technical protocol that we describe in detail.

Anal fistula in association with chronic anal fissure (fissure-fistula) is infrequently described. Recognizing this association and managing both components may help prevent some treatment failures seen with chronic anal fissure. This study aims to report on the outcomes of 20 consecutive patients with fissure-fistula managed with fistulotomy and injection of botulinum A toxin. The study is a retrospective, observational study, assessing the success of symptom resolution following fistulotomy with botulinum A toxin, in patients identified as having a chronic anal fissure with associated anal fistula. The study included all patients with this condition treated with combination treatment by a single surgeon at a tertiary care hospital between January 2013 and January 2016. Twenty patients with fissure-fistula treated with fistulotomy and botulinum toxin A were identified. The median cohort age was 44 years (range 25-78), with a predominance of males (80%) and posterior fissure position (80%). The most common presenting symptoms were anal pain (70%), rectal bleeding (55%), anal discharge (35%) and anal pruritus (35%). Mean follow-up was 10.5 weeks and all patients who attended follow-up appointments reported resolution of symptoms. There were no cases of incontinence and none of the cohort required further surgical intervention for the condition. Chronic anal fissure with associated anal fistula can be successfully managed with fistulotomy and injection of botulinum toxin A. Further studies would be helpful in determining if recognition and management of the fistula component in isolation with fistulotomy is as effective as fistulotomy plus botulinum A toxin. © 2017 Royal Australasian College of Surgeons.

Patients with postradiation therapy for malignancies and/or extensive colorectal surgery are prone to the development of enteroperineal fistulas. Application of biological meshes may prove beneficial in treating complicated enteroperineal fistulas as they provide a stable ground for closing pelvic defects even in contaminated fields.

Transcatheter Amplatzer vascular plug-embolization of a giant postnephrectomy arteriovenous fistula combined with an aneurysm of the renal pedicle by through-and-through, arteriovenous access

PubMed Central

Kayser, Ole; Schäfer, Philipp

2013-01-01

Although endovascular transcatheter embolization of arteriovenous fistulas is minimally invasive, the torrential flow prevailing within a fistula implies the risk of migration of the deployed embolization devices into the downstream venous and pulmonary circulation. We present the endovascular treatment of a giant postnephrectomy arteriovenous fistula between the right renal pedicle and the residual renal vein in a 63-year-old man. The purpose of this case report is to demonstrate that the Amplatzer vascular plug (AVP) can be safely positioned to embolize even relatively large arteriovenous fistulas (AVFs). Secondly, we illustrate that this occluder can even be introduced to the fistula via a transvenous catheter in cases where it is initially not possible to advance the deployment-catheter through a tortuous feeder artery. Migration of the vascular plug was ruled out at follow-up 4 months subsequently to the intervention. Thus, the Amplatzer vascular plug and the arteriovenous through-and-through guide wire access with subsequent transvenous deployment should be considered in similar cases. PMID:23326248

Dural arteriovenous fistulas located in the vicinity of the jugular foramen are complex vascular malformations and belong to the most challenging skull base lesions to treat. The authors comprehensively analyze multiple features in a series of dural arteriovenous fistulas with transosseous arterial feeders involving the jugular bulb. Four patients who underwent surgery via the transcondylar approach to treat dural arteriovenous fistulas around the jugular foramen were retrospectively reviewed. Previously, endovascular treatment was attempted in all patients. The success of the surgical treatment was examined with postoperative angiography. Complete obliteration of the dural arteriovenous fistulas (DAVFs) was achieved in three patients, and significant flow reduction in one individual. All patients had a good postoperative outcome, and only one experienced mild hypoglossal nerve palsy. Despite extensive bone drilling, an occipitocervical fusion was necessary in only one patient with bilateral lesions. The use of an individually tailored transcondylar approach to treat dural arteriovenous fistulas at the region of the jugular foramen is most effective. This approach allows for complete obliteration of the connecting arterial feeders, and removal of bony structures containing pathological vessels.

The aim of this study was to primarily investigate the usefulness of computerized tomographic (CT) fistulography in the diagnosis and management of branchial cleft fistulae and sinuses. Fifteen patients with confirmed branchial fistulae or sinuses who had undergone CT fistulography were included. The diagnoses were confirmed by clinical, radiologic, or histopathologic examinations. The internal openings, distribution, and neighboring relationship of the lesions presented by CT fistulography were analyzed to evaluate the usefulness in comparison with x-ray fistulography. Nine patients were diagnosed with first branchial fistulae or sinuses, 2 with second branchial fistulae, and 4 with third or fourth branchial fistulae. The presence and location of the lesions could be seen on x-ray fistulography. The distribution of the lesions, internal openings, and neighboring relationship with parotid gland, carotid sheath, and submandibular gland could be clearly demonstrated on CT cross-sectional or volume-rendering images. CT fistulography could provide valuable information and benefit surgical planning by demonstrating the courses of branchial anomalies in detail. Copyright © 2012 Elsevier Inc. All rights reserved.

Certain broncho-oesophageal fistulae require surgical repair. Herein, we describe an innovative surgical technique combining intercostal flap and endobronchial stenting. Two patients, each with a with complex broncho-oesophageal fistula 2 years after radio-chemotherapy, were hospitalised for severe respiratory infection and extension of the fistula despite previous endoscopic treatment. The first patient presented with respiratory distress (ARDS). She had emergency surgery under extra corporeal membrane oxygenation: oesophagectomy and reconstruction of the left bronchus by a vascularised intercostal flap. Stenting was performed on day 10, due to persistence of the fistula. At 3 months the bronchus was healed, but the patient died of cerebral bleeding. For the second patient, repair was proposed before severe ARDS with the same surgical and ventilatory strategy and a stent was preventively inserted after surgery. After 3 months, the stent was removed and the left bronchus was healed. Complex post-radiotherapy broncho-oesophageal fistulae should be treated surgically before respiratory complications arise, by combining reconstruction with a vascularised flap and transient stenting.

The effects of obstetric fistula surpass the individual woman and affect husbands, relatives, peers and the community at large. Few studies have documented the experiences of men who live with wives suffering from fistula. In this study, our objective was to understand how fistula affects these men's lives. We conducted 16 in-depth interviews with men in central and western Uganda. We used thematic narrative analysis and discuss our findings based on Connell's theory of hegemonic masculinity. Findings show that the men's experiences conflicted with Ugandan norms of hegemonic masculinity. However, men had to find other ways of explaining their identity, such as portraying themselves as small men but still be responsible, caring husbands and fathers. The few individuals who married a second wife remained married to the wife with the fistula. These men viewed marriage as a lifetime promise before God and a responsibility that should not end because of a fistula. Poverty, love, care for children and social norms in a patriarchal society compelled the men to persevere in their relationship amidst many challenges.

The appropriate surgical stump closure after distal pancreatectomy (DP) is still controversial. This study investigated the benefits and risks of stapler closure during DP. The risk factors of pancreatic fistulas were investigated in 122 DPs among 3 types of stump closure: hand-sewn suture (n = 32), bipolar scissors (n = 45), and stapler closure (n = 45). There was no significant difference in the incidence of pancreatic fistula between the 3 types of stump closure (hand-sewn suture [44%] vs bipolar scissors [37.7%] vs stapler closure [35.5%]). By using receiver operating characteristics curves, 12 mm was the best cutoff value of the thickness of the pancreas for pancreatic fistulas after DP using stapler closure. Three factors (ie, male sex, body mass index >25 kg/m(2), and stapler closure) were independent risk factors of pancreatic fistulas after DP with a pancreas thicker than 12 mm. A pancreas thicker than 12 mm significantly increased the incidence of pancreatic fistulas after DP using stapler closure. Copyright © 2013 Elsevier Inc. All rights reserved.

Neoplastic sigmoid-uterine fistula is an extremely rare condition because the uterus is a thick and muscular organ. A 74-year-old woman was admitted to the First Aid Station suffering from abdominal pain and foul smelling vaginal discharge. Gynaecological examination showed fecal drainage from the cervical orifice, while the uterus was regular in size but very firm and painful. Ovaries and fallopian tubes were not palpable owing to abdominal tenderness. Ultrasounds reveled inhomogeneous thickening of uterine cavity, without detecting fistula. Contrast Medium CT (CMCT) showed Douglas’ recto-uterine pouch occluded. The sigmoid wall was very thin exception a site where a fistula was suspected. At the surgery severe adhesions of the sigma-rectum with the posterior uterine wall were observed. After adhesiolysis, 18 cm colon-sigma-rectum was removed. Total hysterectomy with salpingooophorectomy was performed. Lymphadenectomy ended the procedure. Anatomical specimen confirmed sigmoid-uterine fistula. At histology a mildly differentiated adenocarcinoma of sigma-rectum was shown. Postoperative course was uneventful. Such a case of neoplastic sigmoid-uterine fistula has not been reported so far.

Computed tomography colonography, or virtual colonoscopy, is a good alternative to optical colonoscopy. However, suboptimal patient preparation or colon distension may reduce the diagnostic accuracy of this imaging technique. We report the case of an 83-year-old Caucasian woman who presented with a five-month history of pneumaturia and fecaluria and an acute episode of macrohematuria, leading to a high clinical suspicion of a colovesical fistula. The fistula was confirmed by standard contrast-enhanced computed tomography. Optical colonoscopy was performed to exclude the presence of an underlying colonic neoplasm. Since optical colonoscopy was incomplete, computed tomography colonography was performed, but also failed due to inadequate colon distension. The insufflated air directly accumulated within the bladder via the large fistula. Clinicians should consider colovesical fistula as a potential reason for computed tomography colonography failure.

Postoperative pancreatic fistula and pancreas-specific complications have a significant influence on patient management and outcomes after pancreatoduodenectomy. The aim of the study was to assess the value of serum C-reactive protein on the postoperative day 1 as early predictor of pancreatic fistula and pancreas-specific complications. Between 2013 and 2016, 110 patients underwent pancreaticoduodenectomy. Clinical, biological, intraoperative, and pathological characteristics were prospectively recorded. Pancreatic fistula was graded according to the International Study Group on Pancreatic Fistula classification. A composite endpoint was defined as pancreas-specific complications including pancreatic fistula, intra-abdominal abscess, postoperative hemorrhage, and bile leak. The diagnostic accuracy of serum C-reactive protein on postoperative day 1 in predicting adverse postoperative outcomes was assessed by ROC curve analysis. Six patients (5%) died and 87 (79%) experienced postoperative complications (pancreatic-specific complications: n = 58 (53%); pancreatic fistula: n = 48 (44%)). A soft pancreatic gland texture, a main pancreatic duct diameter < 3 mm and serum C-reactive protein ≥ 100 mg/L on postoperative day 1 were independent predictors of pancreas-specific complications (p < 0.01) and pancreatic fistula (p < 0.01). ROC analysis showed that serum C-reactive protein ≥ 100 mg/L on postoperative day 1 was a significant predictor of pancreatic fistula (AUC: 0.70; 95%CI: 0.60-0.79, p < 0.01) and pancreas-specific complications (AUC: 0.72; 95%CI: 0.62-0.82, p < 0.01). ROC analysis showed that serum C-reactive protein ≥ 50 mg/L at discharge was a significant predictor of 90-day hospital readmission (AUC: 0.70; 95%CI: 0.60-0.79, p < 0.01). C-reactive protein levels reliably predict risks of pancreatic fistula, pancreas-specific complications, and hospital readmission, and should be inserted in risk-stratified management algorithms after pancreaticoduodenectomy.

Postoperative pancreatic fistula represents the most important complication after distal pancreatectomy. The aim of this study was to evaluate the use of a preoperative endoscopic injection of botulinum toxin into the sphincter of Oddi to prevent postoperative pancreatic fistula (German Clinical Trials Register number: DRKS00007885). This was an investigator-initiated, prospective clinical phase I/II trial with an exploratory study design. We included patients who underwent preoperative endoscopic sphincter botulinum toxin injection (100 units of Botox). End points were the feasibility, safety, and postoperative outcomes, including postoperative pancreatic fistula within 30 days after distal pancreatectomy. Botulinum toxin patients were compared with a control collective of patients undergoing distal pancreatectomy without botulinum toxin injection by case-control matching in a 1:1 ratio. Between February 2015 and February 2016, 29 patients were included. All patients underwent successful sphincter of Oddi botulinum toxin injection within a median of 6 (range 0-10) days before operation. One patient had an asymptomatic, self-limiting (48 hours) increase in serum amylase and lipase after injection. Distal pancreatectomy was performed in 24/29 patients; 5 patients were not resectable. Of the patients receiving botulinum toxin, 7 (29%) had increased amylase levels in drainage fluid on postoperative day 3 (the International Study Group of Pancreatic Surgery definition of postoperative pancreatic fistula grade A) without symptoms or need for reintervention. Importantly, no clinically relevant fistulas (International Study Group of Pancreatic Surgery grades B/C) were observed in botulinum toxin patients compared to 33% postoperative pancreatic fistula grade B/C in case-control patients (P < .004). Preoperative sphincter of Oddi botulinum toxin injection is a novel and safe approach to decrease the incidence of clinically relevant postoperative pancreatic fistula after distal pancreatectomy. The results of the present trial suggest its efficacy in the prevention of clinically relevant postoperative pancreatic fistula and are validated currently in the German Federal Government-sponsored, multicenter, randomized controlled PREBOT trial.

Complete closure of the fistula was achieved in 11 patients (79%), with partial closure in the remaining three patients. This technique is simple, causes relatively little discomfort, involves little tissue dissection and can be performed as a day-case procedure. The success rate is comparable with or better than other methods, and we consider it the treatment of choice for small cleft palate fistulae.

Postoperative systemic artery to pulmonary vein fistula is very rare. In this report, we describe an exceptional condition of both intrapulmonary arteriovenous fistula and systemic artery to pulmonary vein fistula, involving all right hemithoracic systemic arteries, inducing left-to-left shunt. This condition was responsible for heart failure, 24 years after a right upper lobectomy for inflammatory tumor. Investigations included computed tomographic angiography, arteriography, and four-dimensional flow magnetic resonance imaging. Differential diagnosis and management are discussed.

2015-01-01

Lower esophageal fistula is a rare complication after upper digestive tract surgery, but it is associated with high morbi-mortality. There is no consensus on therapeutic care, however when reoperation is necessary, a pedicled inter-costal flap from the thoracotomy can be easily harvested to patch a large defect or buttress a direct suture, saving -digestive reconstruction. This technique should be mastered by thoracic and general surgeons. We present here two cases of lower esophagus fistulas cured thanks to this intercostal flap, in which we avoided fistula recurrence with maintenance of digestive continuity.

Nutritional support in patients with gastrointestinal fistula.

PubMed

Yanar, F; Yanar, H

Gastrointestinal fistulas (GIFs) arise as a complication of the surgical treatment of a number of malignant and non-malignant diseases. Fluid loss and electrolyte and nutritional imbalance are related to increased morbidity and mortality in these patients. A multidisciplinary approach under the leadership of the surgeon is essential for successful therapy. Because complication rates are higher in malnourished patients with fistulas, enteral or total parenteral nutritional (TPN) support should be initiated after the patient has been stabilized with respect to fluid loss, acid-base, and sepsis. Pharmacotherapy with somatostatin and octreotide has been shown to reduce fistula output and shorten closure time.

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

2017-08-01

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

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.

This study aimed to evaluate the usefulness of four-dimensional CTA before and after embolization treatment with ONYX-18 in eleven patients with cranial dural arteriovenous fistulas, and to compare the results with those of the reference standard DSA. Eleven patients with cranial dural arteriovenous fistulas detected on DSA underwent transarterial embolization with ONYX-18. Four-dimensional CTA was performed an average of 2 days before and 4 days after DSA. Four-dimensional CTA and DSA images were reviewed by two neuroradiologists for identification of feeding arteries and drainage veins and for determining treatment effects. Interobserver and intermodality agreement between four-dimensional CTA and DSA were assessed. Forty-two feeding arteries were identified for 14 fistulas in the 11 patients. Of these, 36 (85.71%) were detected on four-dimensional CTA. After transarterial embolization, one patient got partly embolized, and the fistulas in the remaining 10 patients were completely occluded. The interobserver agreement for four-dimensional CTA and intermodality agreement between four-dimensional CTA and DSA were excellent (κ=1) for shunt location, identification of drainage veins, and fistula occlusion after treatment. Four-dimensional CTA images are highly accurate when compared with DSA images both before and after transarterial embolization treatment. Four-dimensional CTA can be used for diagnosis as well as follow-up of cranial dural arteriovenous fistulas in clinical settings. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

To assess the effect of early pregnancy on obstetric fistula. A prospective observational study was conducted among patients with obstetric fistula caused by a long obstructed labor who presented at Selian Lutheran Hospital, Tanzania, or Kitovu Hospital, Uganda, between January 1, 2015, and January 31, 2016. Demographic and clinical variables were evaluated. Among 270 patients, 162 (60.0%) experienced their first pregnancy up to 2 years after menarche (early group) and 108 (40.0%) experienced their first pregnancy more than 2 years after menarche (late group). No significant differences between the early and late groups were found for median age at presentation (30.0 vs 28.0 years), median parity (both 2.0), stillbirth (n=145 [89.5%] vs n=95 [88.0%]), median duration of labor (both 2.0 days), home delivery (n=31 [19.1%] vs n=17 [15.7%]), cesarean delivery (n=79 [48.8%] vs 58 [53.7%]), median time from obstetric fistula formation to presentation (48.0 vs 24.0 months), and obstetric fistula classifications. Obstetric fistula occurred during the first pregnancy in 99 (61.1%) women in the early group and 71 (65.7%) in the late group (P=0.440). Frequency of obstetric fistula during the first pregnancy is not increased among women who experience their first pregnancy within 2 years of menarche. © 2017 International Federation of Gynecology and Obstetrics.

Thoracic Duct Chylous Fistula Following Severe Electric Injury Combined with Sulfuric Acid Burns: A Case Report.

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.

Embolization of direct carotid cavernous fistulas with the novel double-balloon technique

2015-01-01

Multiple endovascular management of direct carotid cavernous fistula (CCF) has been widely accepted as a treatment option. Embolization of the fistula with detachable balloons or thrombogenic coil-based occlusion has been the main choice to treat direct CCF, with good safety and efficacy. This study investigated the safety and efficacy of embolization of direct CCF with the novel double-balloon technique. A retrospective review of a prospective database on cerebral vascular disease was performed. We identified a total of five patients presenting with high-flow direct CCF. All patients were managed with transarterial embolization with the novel double-balloon technique. Three of the five patients were treated with two detachable balloons, and a completely occluded fistula with preservation of the internal carotid artery was achieved. Of the remaining two patients treated with more detachable balloons, one patient achieved a perfect outcome and the other one suffered from recurrent fistula due to balloon migration 3 weeks after embolization. During a follow-up period of 12–18 months, no symptoms reoccurred in any patient. Thus, the double-balloon treatment may be a promising method for CCF complete occlusion. This novel technique may bring more benefits in the following two cases: 1). A single inflated detachable balloon fails to completely occlude the CCF, which causing the next balloon can not pass into the fistula. 2). A giant CCF needs more balloons for fistula embolization.

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

NASA Astrophysics Data System (ADS)

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

2011-11-01

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

[Multiple coronary arteriovenous fistulae. Hazard or predetermination?].

2003-01-01

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

High levels of mental health dysfunction have been identified in women with genital tract fistula. The aim of this study was to use the General Health Questionnaire-28 (GHQ-28) to screen women in western Uganda with severe pelvic organ prolapse, chronic fourth-degree obstetric tear and genital tract fistula for risk of mental health dysfunction. Women undergoing surgery for severe pelvic organ prolapse, chronic fourth-degree obstetric tear, and genital tract fistula were interviewed using the GHQ-28 to screen for the risk of mental health dysfunction. A total of 125 women completed the GHQ-28, including 22 with pelvic organ prolapse, 47 with fourth-degree obstetric tear, 21 with genital tract fistula, and 35 controls. Nearly all women with these serious gynaecological conditions were positive for the risk of mental health dysfunction. In the domain assessing symptoms of severe depression, women with fourth-degree obstetric tear and genital tract fistula scored higher than women with pelvic organ prolapse. A significant risk of mental health dysfunction was identified in women with severe pelvic organ prolapse and chronic fourth-degree obstetric tear. These rates are similar to the high rates of mental health dysfunction in women with genital tract fistula. Identification and management of mental health dysfunction in women with these conditions should be a priority.

Nigeria task force alerts public to fistula hazards.

PubMed

1994-01-01

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

The purpose of this study was to evaluate the safety and effectiveness of a barbed silicone-covered retrievable expandable nitinol stent in preventing stent migration in patients with tracheal strictures or fistulas. Under fluoroscopic guidance, barbed silicone-covered retrievable expandable nitinol stents were placed in 15 patients with tracheal strictures, two patients with fistulas, two patients with combined strictures and fistulas, and one patient with variable extrathoracic airway obstruction. The three pairs of barbs were attached to the external stent surface at the middle of the stent at equal intervals. Technical success, improvement in respiratory status, complications, and related interventions were evaluated. The technical success rate was 100%, and respiratory status improved or the fistula closed in all 20 patients. Complications included sputum retention (three patients), tumor overgrowth (three patients), pain (one patient), and granulation tissue formation (one patient). No stent migration occurred, even in the three patients without fixed strictures. Four stents subsequently were removed because of complications, and one stent was removed because the patient's condition improved. Stent removal was not difficult and was uneventful. The silicone membranes and barbs of the removed stents were intact. Use of a barbed silicone-covered retrievable expandable nitinol stent relieves dyspnea and facilitates fistula closure in patients with benign or malignant tracheal strictures or fistulas. The barbed design of the stent is important in preventing migration.

Obstetric fistula and pelvic organ prolapse remain highly prevalent in sub-Saharan Africa, where women have poor access to modern health care. Women having these problems tend to stay at home for years before getting treatment. However, information regarding the reasons contributing to late presentation to treatment is scarce, especially at the study area. The objective of this study was to assess the reasons whywomen with obstetric fistula and pelvic organ prolapse at Gondar University Hospital delay treatment. A hospital based cross-sectional study was conducted among 384 women. Delay was evaluated by calculating symptom onset and time of arrival to get treatment at Gondar University Hospital. Regression analysis was conducted to elicit predictors of delay for treatment. Of the total 384 participants, 311 (80.9%) had pelvic organ prolapse and 73(19.1%) obstetric fistula. The proportion of women who delayed treatment of pelvic organ prolapse was 82.9% and that of obstetric fistula 60.9%. Fear of disclosing illness due to social stigma (AOR = 2; 1.03, 3.9) and lack of money (AOR = 1.97; 1.01, 3.86) were associated with the delay of treatment for pelvic organ prolapse,while increasing age (AOR =1.12; 1.01, 1.24) and divorce (AOR = 16.9; 1.75, 165.5) were were responsible for delaying treatment forobstetric fistula. A large numberof women with pelvic organ prolapse and obstetric fistula delayed treatment. Fear of disclosure due to social stigma and lack of moneywere the major factors that contributed to thedelay to seek treatment for pelvic organ prolapse,while increasing age and divorce were the predictors for delaying treatment for obstetric fistula.

Anastomotic leakage is one of the most important causes of morbidity and mortality in gastrointestinal surgery. We investigated the effect of oral glutamine on the healing of high-output intestinal fistula. A tertiary Universitary Hospital of the University of Mato Grosso, Cuiaba, Brazil. 28 patients (25 males and 3 females; median age = 45 [18-71] years old) admitted with high output post-operative small bowel fistulas (median volume in 24 h: 850 [600-2,200] mL) during a 4 years period were retrospectively studied. In the first two years 19 (67.9%) patients received only TPN as the initial nutritional support. In the last two years however, due to a change in the protocol for the nutritional support in cases of intestinal fistula 9 patients (32.1%) received oral glutamine (0.3 g/kg/day; 150 mL/day) in addition to TPN. Endpoints of the study were mortality, resolution of the fistula, and length of hospital stay (LOS). The overall mortality was 46.4% (13 patients). Fistula closure was observed in all other 15 patients (53.6%) that survived. In the subset of survived patients LOS was similar in those who received or not received glutamine. The multivariate regression analysis showed that resolution of the fistula was 13 times greater in patients that received oral glutamine (OR = 13.2 (95% CI = 1.1-160.5); p = 0.04) and 15 times greater in non-malnourished patients (OR = 15.4 [95% CI = 1.1-215.5]; p = 0.04). We conclude that oral glutamine accelerated the healing and diminished the mortality in this series of patients with post-operative high-output intestinal fistula receiving TPN.

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.

This study was intended to examine the effect of selective soothing music on fistula puncture-related pain in hemodialysis patients. This is a randomized clinical trial in which 114 participants were selected from two hemodialysis units by means of a non-random, convenience sampling method. The participants were then allocated in three groups of music (N = 38), headphone (N = 38), and control (N = 38). The fistula puncture-related pain was measured 1 min after venipuncture procedure in all three groups. The music group listened to their self-selected and preferred music 6 min before needle insertion into a fistula until the end of procedure. The headphone group wore a headphone alone without listening to music 6 min before needle insertion into a fistula until the end of procedure. The control group did not receive any intervention from the research team during needle insertion into a fistula. The pain intensity was measured immediately after the intervention in all three groups. This study showed a significant difference between the music and control groups, and the music and headphone groups in terms of the mean pain score after the intervention. However, the analysis did not indicate any significant difference between the headphone and control groups with regard to the mean pain score after the intervention. It is concluded that music can be used effectively for pain related to needle insertion into a fistula in hemodialysis patients. Future research should investigate the comparative effects of pharmacological and non-pharmacological interventions on fistula puncture-related pain. Copyright © 2017 Elsevier Ltd.

External bile duct fistulas are inherent postoperative complications that usually appear after biliary tract surgery, traumatic bile duct injuries and liver surgery for hepatic hydatid disease or liver transplant. The management is highly individualized, while the success and long-term results of endoscopic and surgical techniques are conflicting. The study included 32 cases with external bile duct fistulas managed by endoscopic retrograde cholangiography (ERC) with sphincterotomy and/or stent placement, including "rendez-vous" procedures in 2 cases. The causes of the external fistula were represented by cholecystectomy with/without retained common bile duct stones or strictures (22 cases), cholecystectomy and drainage of a subphrenic abscess caused by severe acute pancreatitis (1 case) and surgical interventions for hepatic hydatid disease (9 cases). Due to the prospective protocol of the study we were able to apply an individualized endoscopic treatment: sphincterotomy with proper relief of the bile duct obstruction (stone extraction) or sphincterotomy with large-size (10 Fr) stent placement for large-sized bile duct defects. The results consisted in closure of the fistula in 3.5 +/- 1.7 days for the subgroup of patients with sphincterotomy alone. Among the patients with stent insertion, fistulas healed slower in 14 +/- 3.5 days. There were no complications after endoscopic treatment; however the stent could not be passed in one patient that required subsequent surgery. In conclusion, endoscopic intervention is the treatment of choice for small external biliary fistulas complicating biliary tract surgery or liver surgery for hepatic hydatid disease. When the fistula is large, the placement of a 10 Fr endoprosthesis becomes necessary, while failure of endoscopic treatment leads to surgery with hepatico-jejunal anastomosis.

One of the frequently encountered disorders of wound healing following laryngectomy is pharyngocutaneous fistula. However, although studies have been performed with the aim of prevention of pharyngocutaneous fistulae, there are very few studies with tissue adhesives and platelet-rich plasma. In this study, our aim was to investigate the histopathologic changes in wound healing caused by various tissue adhesives and platelet-rich plasma, together with their effects on prevention of pharyngocutaneous fistula. 40 male rats were randomly divided into five groups: control, platelet-rich plasma, fibrin tissue adhesive, protein-based albumin glutaraldehyde and synthetic tissue adhesive groups. The pharyngotomy procedure was performed and was sutured. Except the control group, tissue adhesives and platelet-rich plasma were applied. Then, the skin was sutured. On the seventh day, the rats were sacrificed. The skin was opened and pharyngotomy site was assessed in terms of fistulae. The pharyngeal suture line was evaluated histopathologically by using Ehrlich Hunt scale. Inflammatory infiltration was found to be higher in "platelet-rich plasma" group than "fibrin tissue adhesive" and "synthetic tissue adhesive" groups. The fibroblastic activity of "platelet-rich plasma", "fibrin tissue adhesive" and "protein-based albumin glutaraldehyde" groups was higher than the control group. The positive changes created by platelet-rich plasma and fibrin tissue adhesive at the histopathologic level were found together with no detected fistula. Among the study groups, there was no statistical difference for pharyngeal fistula development. This result may be obtained by the small number of animal experiments. These results shed light on the suggestion that platelet-rich plasma and fibrin tissue adhesive can be used in clinical studies to prevent pharyngocutaneous fistula.

To investigate the efficacy and safety of membrane-covered self-expanding metal stent in the treatment of high-positioned esophageal diseases, including esophageal stenosis, esophagotracheal fistula and anastomotic stricture. Clinical data of 84 patients who underwent stenting in our center from May 2005 to July 2013 were retrospectively analyzed. Of 84 patients, 31 were diagnosed as esophageal malignant stenosis, 2 compression stenosis, 10 radiation stenosis, 4 recurrent malignant stenosis, 27 anastomotic stricture, 1 esophageal stenosis after endoscopic submucosal dissection (ESD), 7 esophageal-tracheal fistula, 1 esophageal-mediastinal fistula, and 1 remnant stomach fistula. Distance from stenosis or fistula to central incisor was 15-20 cm in 48 cases, and more than 20 cm in 36 cases. All the patients were treated by 16 mm membrane-covered self-expanding metal stents. Main clinical manifestations and complications were evaluated. A total of 100 stents were placed in 84 patients,with a success rate of 100%. There were no complications such as perforation and bleeding during operation. Dysphagia and cough were improved quickly with a success rate of 100%. After the placement of stents, the incidence of complication was 6.0% (5/84), of which 2 cases were severe retrosternal pain, 1 was tracheal collapse, and 2 were stent displacement. Seventy-six patients (90.5%) received complete follow-up of 1 to 36 months (mean 15 months). Re-stenosis occurred in 4 cases, new esophageal-tracheal fistula in 2 cases. Among these 6 cases, 5 cases underwent successfully stent placement once again, and another one case received Savary bougie and Argon-ion coagulation with good efficacy. Endoscopic membrane-covered self-expanding metal stent placement is effective and safe for the relieve of dysphagia symptoms and the sealing of esophagotracheal fistula.

To evaluate the ability of parents to recall past injuries to their children's maxillary primary incisors. Clinical and radiographic trauma-related major and minor signs observed in the first dental visit of 727 preschool children were recorded. Major signs included crown fracture, coronal discoloration, internal resorption, pulp canal obliteration, swelling, fistula, and periapical lesion. Minor signs included enamel cracks, sensitivity to percussion, dull or metallic sound on percussion, increased mobility, and widened periodontal ligament. Children were divided into groups: CT = certainly traumatized (presenting with at least one major sign or a combination of three minor signs), PT = probably traumatized (presenting with one or two minor signs) and NT = not traumatized. Accompanying parents were asked to recall past injuries to their children's teeth. Possible replies were 'no', 'yes' and 'probably yes'. Disagreement when both parents were present was recorded as 'yes'. Crown fractures involving dentin, coronal discoloration, swelling and fistula were defined as 'observable signs of trauma'. One-hundred and eighteen children were accompanied by fathers, 411 by mothers and 198 by both. The CT group comprised 464 children; the PT group, 103; and the NT group, 160, with no statistically significant differences by gender. Parents' positive recall was similar for boys (33.3%) and girls (31.0%). Mothers recalled trauma in 32.6% and fathers in 27.1% of their children. Parents failed to recall trauma in 52.6% of the CT-group children and in 43.5% of the PT-group children. Parents failed to recall trauma in 37.6% of the children who had observable signs of trauma. Parents' recall of dental trauma occurring in their children's maxillary primary incisors was reliable in <50% of the cases. © 2011 John Wiley & Sons A/S.

To evaluate the role of subdartos fascial tissue as watertight layer in improving outcome for 2-stage proximal hypospadias surgery. The experimental study was conducted at the Department of Urology, Indus Hospital, Karachi, and comprised an audit of patients with proximal hypospadias who underwent surgery from July 1, 2007, to December 31, 2011. The initial two-stage repair of proximal hypospadias led to a high rate of urethrocutanous fistula formation (Group A), and, thus, a modification was introduced and subdartos facial double layer was applied over the urethral suture line (Group B). The results were compared regarding age, type of hypospadias, graft failure and urethrocutanous fistula in these patients. There were 27 patients in Group A and 16(59.3%) of them ended up having urethrocutanous fistula. Group B had 25 patients and only 2(8%) had fistula formation. The application of dartos facial flap waterproofing layer reduced fistula rate.

To summarize the experience in nutritional support for the management of duodenocutaneous fistula. Data of 32 patients with duodenocutaneous fistula in Zhejiang provincial people's hospital from January 1999 to December 2009 were analyzed retrospectively. The mean duration of nutritional support was 35.6 days (range, 8-82 days). Eight received total parenteral nutrition, 2 total enteral nutrition, and 22 parenteral nutrition combined with enteral nutrition respectively. Succus entericus reinfusion with enteral nutrition was used in 11 cases, glutamine-enriched nutritional support in 28 cases, somatostatin in 12 cases. In these patients, the healing rate was 75.0% after conservative treatment. In the 8 patients who underwent surgery, 6 were cured and 2 died (due to severe abdominal infection and multiple organ failure). A total of 30 patients had the fistulas cured and discharged. Parenteral nutrition combined with enteral nutrition, succus entericus reinfusion combined with enteral nutrition, glutamine-enriched nutritional support and somatostatin are important factors for the healing of duodenocutaneous fistulas.

Delayed diagnosis of xanthogranulomatous pyelonephritis in a quadriplegic patient with uncontrolled cutaneous fistula

Abstract Rationale: Xanthogranulomatous pyelonephritis (XGP) is a chronic destructive granulomatous inflammation that is characterized by urinary tract obstruction and invasion of the renal parenchyma. Although rare, XGP can lead to fatal complications, including perinephric inflammation, psoas abscess, and cutaneous fistula. Patient concerns: A quadriplegic patient initially presented to the hospital with a chronic open wound and cutaneous fistula. Diagnoses: Abdominal computed tomography revealed a renal obstructing stone and enlarged right kidney with a perinephric fluid collection that communicated with the cutaneous fistula. Interventions: The patient underwent a right nephrectomy at the department of urology. Outcomes: Two months after surgery, the patient was clinically well with no discharging fistula. Lessons: The XGP accompanied by complications requires an immediate evaluation and early diagnosis. In this case, the diagnosis was delayed because the state of quadriplegia rendered no symptoms of XGP. PMID:29480882

2011-09-01

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.

Indocyanine green video-angiography as an aid to surgical treatment of spinal dural arteriovenous fistulae.

2010-03-01

To illustrate the use of indocyanine green (ICG) video-angiography to confirm abolition of spinal dural arteriovenous fistula (SDAVF) and preserve the normal vascular anatomy intraoperatively. A 73-year-old woman presenting with progressive myelopathy was diagnosed with an SDAVF, where the origin of the fistula was in close proximity to the origin of the posterior spinal artery. ICG was injected intravenously. Using a filter on the microscope, dynamic filling of the abnormal vasculature was visualised. After applying a clip to the fistulous connection, we were able to see the successful interruption of the dural fistula, on-table in real time. ICG video angiography confirmed interruption of the fistula and preservation of the associated posterior spinal artery. We find the application of this relatively new technology has the potential to shorten operating times, gives additional reassurance of completeness of surgical treatment and preservation of normal spinal vasculature.

To know the diagnostic tools and proper management of ureterovaginal fistula following neglected vaginal foreign body in order to achieve optimal outcome. A case of ureterovaginal fistula associated with a neglected vaginal foreign body. The patient was complaining of a foul-smelling vaginal discharge and lower abdominal pain. On vaginal examination, a hard and large foreign body was found. Examination under anesthesia was performed, and an aerosol cap was removed from her vagina. The patient developed urinary incontinence after removal of the foreign body. Subsequent work-up demonstrated the presence of a right ureterovaginal fistula. The patient underwent an abdominal ureteroneocystostomy. At one year follow up, the patient had fully recovered. Ureterovaginal fistula following neglected vaginal foreign body is a serious condition. Early diagnosis, treatment of infection and proper surgical management can improve the outcome and decrease complications. Copyright © 2018. Published by Elsevier B.V.

To present our initial experience using a dermal regeneration sheet as an urethral cover in the repair of recurrent urethrocutaneous fistulae in pediatric patients. Since May 2016 to March a total of 8 fistulaes were repaired using this new technique. We performed the ddissection of the fistulous tract and posterior closure of the urethral defect. A dermal regeneration sheet was used to cover the urethral suture. Finally a rotational flap was performed to avoid overlap sutures. During the follow-up (average 6 months), one patient presented in the immediate postoperative period infection of the surgical wound. This patient presented recurrence of the fistula. 88% of the patients included presented a good evolution with no other complications. In our initial experience the new technique seems easy, safe and effective in the management of the recurrent urethrocutaneous fistulae in pediatric patients. More studies are needed to prove these results.

Obesity is a public health problem, for which the prevalence has increased worldwide at an alarming rate, affecting 1.7 billion people in the world. To describe the technique employed in incomplete penetration of gastric band where endoscopic management and/or primary closure is not feasible. Laparoscopic removal of gastric band was performed in five patients with incomplete penetrance using Foley catheterization in the perforation site that could lead to the development of a gastro-cutaneous fistula. The cases presented include a leak that required surgical lavage with satisfactory outcome, and one patient developed stenosis 3 years after surgical management, which was resolved endoscopically. In all cases, the penetration site closed spontaneously. Gastric band erosion has been reported in 3.4% of cases. The reason for inserting a catheter is to create a controlled gastro-cutaneous fistula, allowing spontaneous closure. Various techniques have been described: the totally endoscopic, hybrid techniques (endoscopic/laparoscopic) and completely laparoscopic. A technique is described here that is useful and successful in cases where the above-described treatments are not viable. Copyright © 2015. Published by Masson Doyma México S.A.

To evaluate the role of selective neck dissection in the treatment of recurrent branchial anomalies. The clinical data of 18 patients with recurrent branchial anomalies were retrospectively analyzed. In accordance with the embryologic and anatomic features of branchial anomalies, different types of selective neck dissection were applied. With dissection and protection of important vessels, nerves and other structures, enbloc resection principles were applied to extirpate branchial lesions, scarrings and inflammatory granuloma during the operation. Of all 18 patients, 16 cases were healed with primary healing, 2 cases with local incision infection were healed after dressing changes. A temporary facial nerve paralysis occurred in 1 case with recurrent first branchial cleft fistula postoperatively, and completely recovered 2 months after operation. A postoperative temporary vocal cord paralysis occurred in 1 case with recurrent fourth branchial cleft fistula, and totally recuperated 1 month after operation. No recurrences were found in all 18 cases with a follow-up period of 12-78 months (average 35 months). Selective neck dissection is a safe and effective surgical procedure for the radical treatment of recurrent branchial anomalies.

A 63-year-old man with bloody stools, anal incompetence, and feeling of fatigue was diagnosed as having a RAS mutanttype rectal cancer with abscess and rectovesical fistula. Computed tomography revealed that the tumor had invaded the seminal vesicle, prostate, and bladder and formed an abscess. In addition, his general condition was poor. Thus, we evaluated the lesion as unresectable. His nutritional status improved, and the infection was controlled after colostomy. Then, we performed chemotherapy with 5-fluorouracil, Leucovorin, and oxaliplatin(FOLFOX)plus bevacizumab. However, after a single course of chemotherapy, the systemic inflammatory reaction was prolonged. Despite treatment of the infection with antibiotics, it was not fully controlled, making it difficult to continue chemotherapy. A new lesion did not appear, but the primary tumor increased in size. Thus, we performed pelvic exenteration. Pathological examination revealed that the tumor was a well-differentiated adenocarcinoma invading the sigmoid colon and bladder. We resected it curatively and administered adjuvant chemotherapy postoperatively. No recurrence was observed during 10 months' follow-up.

2017-04-26

A 68-year-old man presented to the emergency department with haematemesis and shock. Upper endoscopy and selective angiography could not identify the source of bleeding. He underwent selective embolisation of the gastroduodenal artery. The patient then had a period of about 24 hours with relative haemodynamic stability before having another episode of massive upper gastrointestinal bleed. A second attempt to embolise the common hepatic artery and distal coeliac axis was unsuccessful. Hence, he was urgently taken to the operating room for exploratory laparotomy. The source of bleeding could not be identified in the operating room. The patient went into cardiac arrest and expired. Autopsy revealed a fistula between proximal jejunum and a previously unknown abdominal aortic aneurysm (AAA). We present an entity that has only been described a few times in the literature while highlighting the importance of having a broad differential with upper gastrointestinal bleeding, especially when the source is not clearly evident. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

To identify predictors of arteriovenous fistula (AVF) patency in Asian patients with autogenous radio-cephalic arteriovenous fistula (RCAVF). Retrospective review of 436 RCAVFs created between 2009 and 2013. Predictors of patency were identified with univariate and multivariate analysis. Kaplan-Meier survival analysis and log-rank test were used to calculate patency rates. Overall secondary patency rate was 72% at 12 months, 69% at 24 months, 58% at 36 months, 57% at 48 months, 56% at 60 months and 54% at 72 months. Univariate analysis showed that factors which predict for patency include male gender (p = 0.003), good diabetic control (p = 0.025), aspirin use (p = 0.031), pre-dialysis status (p = 0.037), radial artery diameter (p = 0.029) and non-calcified radial arteries (p = 0.002). Age (p = 0.866), cephalic vein diameter (p = 0.630) and surgeon grade (p = 0.472) did not predict for primary AVF failure. Multivariate analysis revealed the male gender to be an independent predictor for patency (odds ratio 1.99, p = 0.01). Subset analysis showed a significantly larger average radial artery diameter of 2.3 mm amongst males, as compared to 1.9 mm amongst females (p = 0.001) and no statistical difference in the average cephalic vein diameter. Within our Asian study population, 12-month patency rate of RCAVF is 72%, 69% at 24 months, 58% at 36 months, 57% at 48 months, 56% at 60 months and 54% at 72 months. Male gender is an independent predictor for RCAVF patency. In females or patients with calcified radial arteries, a more proximal AVF should be considered.

A 75-year-old man referred to the outpatient vascular surgery clinic of Taleghani Hospital (Shaheed Beheshti University of Medicine, Tehran, Iran) due to a local nontender mass in his groin. In his history, it was discovered that the mass had appeared a few months after a gunshot injury. He had a history of shortness of breath with a New York Heart Association functional class fluctuating between II and III, but no history of smoking or addiction. In the physical examination, a 5-cm by 5-cm nonpulsatile mass with engorged vessels was found in the anterior portion of the left groin, which was not tender. An elective arterial angiography revealed an arteriovenous fistula joining the femoral artery to the femoral vein at the left groin. The cardiac assessments revealed cor pulmonale (with a restrictive pattern and diastolic dysfunction) and pulmonary hypertension due to primary pulmonary dysfunction. The patient was anesthetized with a balanced general anesthesia method, considering all relevant cardiac and respiratory monitoring methods and specially withholding drugs increasing pulmonary vascular bed pressure, suppressing the myocardium, or increasing the regurgitant flow across the mitral and, especially, the tricuspid valve. The moment the fistula was closed, a rapid fall in the patient's heart rate was noted, from approximately 60 beats per minute to above 40 beats per minute; this decreased heart rate continued up to a few hours after the surgery and did not accompany any significant hemodynamic derangement including the patient's blood pressure. The patient received his postoperative care in the ordinary surgical ward and was discharged a few days later.

Bronchopleural fistula (BPF) remains a rare but fatal complication of thoracic surgery. The aim of this study was to develop and validate a predictive model of BPF after pulmonary resection and to identify patients at high risk for BPF. From January 2005 to December 2012, 34,000 patients underwent major pulmonary resection (lobectomy, bilobectomy, or pneumonectomy) and were entered into the French National database Epithor. The primary outcome was the occurrence of postoperative BPF at 30 days. The logistic regression model was built using a backward stepwise variable selection. Bronchopleural fistula occurred in 318 patients (0.94%); its prevalence was 0.5% for lobectomy (n = 139), 2.2% for bilobectomy (n = 39), and 3% for pneumonectomy (n = 140). The mortality rate was 25.9% for lobectomy (n = 36), 16.7% for bilobectomy (n = 6), and 20% for pneumonectomy (n = 28). In the final model, nine variables were selected: sex, body mass index, dyspnea score, number of comorbidities per patient, bilobectomy, pneumonectomy, emergency surgery, sleeve resection, and the side of the resection. In the development data set, the C-index was 0.8 (95% confidence interval: 0.78 to 0.82). This model was well calibrated because the Hosmer-Lemeshow test was not significant (χ(2) = 10.5, p = 0.23). We then calculated the logistic regression coefficient to build the predictive score for BPF. This strong model could be easily used by surgeons to identify patient at high risk for BPF. This score needs to be confirmed prospectively in an independent cohort. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Oncologic transoral robotic surgery (TORS) requires in most cases the concurrent or staged surgical treatment of the regional lymph nodes in the neck as well. The purpose of this study was to determine whether the timing of the regional lymphadenectomy (neck dissection) has an impact on the surgical outcomes and on the complication rates. Single-institution, prospective case series with internal control group. Twenty-one patients underwent TORS and appropriate neck dissection concurrently (control group), while 20 patients underwent neck dissection in a timely staged fashion, 8.4 days (median; range, 3-28 days) following their TORS procedure (experimental group). Outcome measures included nodal yield, intraoperative pharyngocervical fistula formation, postoperative fistula formation, postoperative bleeding from the primary and from the neck dissection site, haematoma, seroma, and infection. Nodal yield values, as the oncologic quality indicator of a neck dissection, were comparable in the experimental and in the control group. Complication rates did not differ between the groups: intraoperative and postoperative fistula formation, postoperative bleeding, haematoma and seroma rates were similarly low in the two groups. There was no infection in either group. In the present cohort of 41 TORS-patients, the timing of neck dissection did not make a significant difference in the outcomes. We suggest therefore that aspiring and established TORS-teams do not restrict their appropriate indications due to robotic slot and theatre time constraints, but perform each indicated TORS-case as soon as possible within their given systems, even if the neck dissections cannot be done on the same day.

2007-11-01

Dialysis shunt-associated steal syndrome (DASS) is a rare complication of hemodialysis access (HA) which preferably occurs in brachial fistulas. Treatment options are discussed controversially. Aim of this study was to evaluate flow-controlled fistula banding. Patients treated between 2002 and 2006 were included in this prospective survey. According to a classification we established, patients were typed DASS I-III (I: short history, no dermal lesions; II: long history, skin lesions; III: long history, gangrene). Surgical therapy was HA banding including controlled reduction (about 50% of initial flow) of HA blood flow (patients type I and II). Patients with type III underwent closure of the HA. In 15 patients with relevant DASS, blood-flow-controlled banding was performed. In ten patients (all type I), banding led to restitution of the hand function while preserving the HA. In five patients (all type II), banding was not successful; in two patients, closure of the HA was performed eventually. In five patients (type III), primary closure of the HA was performed. Four patients with DASS type II but only two with DASS type I had diabetes mellitus (p = 0.006). Banding under blood flow control resulting in an approximately 50% reduction in the initial blood flow is an adequate therapeutic option in patients with brachial HA and type I-DASS. In type II-DASS, banding does not lead to satisfying results, more complex surgical options might be more successful. Diabetes is associated with poor HA outcome in case of DASS.

This article describes an unusual case of a vesicocutaneous fistula in a patient with a history of radiation therapy and recent abdominal surgery. A 61-year-old woman was transferred to our acute care facility from a rehabilitation facility, with poor nutritional intake and a concern for urine draining from her wound. A nephrostomy tube was placed (she had only 1 functioning kidney) and negative-pressure wound therapy was used to close the fistula. Urinary diversion via a nephrostomy tube and negative-pressure wound therapy were used to successfully and safely close this vesicocutaneous fistula.

Right-sided valvular (tricuspid, pulmonic) endocarditis is frequently complicated by septic pulmonary embolization. Systemic embolization may also rarely occur due to associated left-sided endocarditis or right-to-left shunting in patients with septal defects. This report documents the occurrence of systemic embolization causing a cerebrovascular accident in an intravenous drug abuser with recurrent tricuspid valve endocarditis due to an isolated peripheral septic pulmonary arteriovenous fistula. Noninvasive diagnosis of the fistula by cardiac auscultation, contrast echocardiography, and nuclear magnetic resonance imaging was confirmed by selective pulmonary angiography. Subselective balloon embolization of the pulmonary arteries feeding this fistula was accomplished.

Temporary banding of the gastroesophageal junction in the critically ill neonate with esophageal atresia and tracheoesophageal fistula.

PubMed

Fagelman, K M; Boyarsky, A

1985-09-01

Patients with esophageal atresia and a distal tracheoesophageal fistula with associated conditions contributing to decreased pulmonary compliance present special problems in management. In the face of positive pressure ventilation, the fistula acts as a vent preventing adequate ventilatory effort from reaching the lungs. A thoracic approach to ligate or divide the fistula carries with it a high mortality rate. A technique is described whereby a silicone rubber band is applied to the gastroesophageal junction to effectively occlude the esophagus. It is designed so that is can be adjusted or removed, without operative intervention, according to the patient's clinical course and growth.

A young intact female dog was presented with urinary incontinence. Abdominal ultrasound revealed the presence of hyperechoic linear structures within the cranial vagina suggestive of foreign material. A computed tomography (CT) retrograde vaginourethrogram demonstrated the presence of a fistulous tract between the urethra and vagina. A presumptive diagnosis of urethrovaginal fistula due to migration of foreign material was made. The grass awn was removed with vaginoscopic-guided retrieval. Fourteen days later, surgical repair of the fistula and an ovariohysterectomy were done. This case report emphasizes the usefulness of CT for diagnosis and precise anatomical localization of genitourinary tract fistulas. © 2015 American College of Veterinary Radiology.

The missing foley catheter: an unusual finding in vesicouterine fistula

A 28-year-old G1P1 presented complaining of urine leakage per vaginum following caesarean delivery, accompanied by amenorrhoea, cyclic haematuria and cyclic pelvic pain. Examination findings were suggestive of vesicouterine fistula and the patient was taken for exploratory laparotomy, during which the foley catheter could not be identified within the bladder. During separation of the bladder from the uterus, the catheter was found to be traversing the fistulous tract into the uterine cavity. Vesicouterine fistula is a fairly uncommon type of urogenital fistula that is frequently associated with caesarean section. Surgical treatment remains the mainstay and successfully cured this patient. PMID:24968444

Is routine drainage necessary after pancreaticoduodenectomy?

2014-01-01

With the development of imaging technology and surgical techniques, pancreatic resections to treat pancreatic tumors, ampulla tumors, and other pancreatic diseases have increased. Pancreaticoduodenectomy, one type of pancreatic resection, is a complex surgery with the loss of pancreatic integrity and various anastomoses. Complications after pancreaticoduodenectomy such as pancreatic fistulas and anastomosis leakage are common and significantly associated with patient outcomes. Pancreatic fistula is one of the most important postoperative complications; this condition can cause intraperitoneal hemorrhage, septic shock, or even death. An effective way has not yet been found to avoid the occurrence of pancreatic fistula. In most medical centers, the frequency of pancreatic fistula has remained between 9% and 13%. The early detection and routine drainage of anastomotic fistulas, pancreatic fistulas, bleeding, or other intra-abdominal fluid collections after pancreatic resections are considered as important and effective ways to reduce postoperative complications and the mortality rate. However, many recent studies have argued that routine drainage after abdominal operations, including pancreaticoduodenectomies, does not affect the incidence of postoperative complications. Although inserting drains after pancreatic resections continues to be a routine procedure, its necessity remains controversial. This article reviews studies of the advantages and disadvantages of routine drainage after pancreaticoduodenectomy and discusses the necessity of this procedure. PMID:25009383

Purpose: Covered, self-expandable metallic stents (SEMS) have been enthusiastically adopted for the treatment of esophagotracheal fistula, but problems with stent migration have yet to be resolved. To overcome this problem, we have developed a new hanging-type esophageal stent designed to prevent migration, and we conducted an animal study to assess the efficacy of our method. Methods: A total of six female pigs were used in this study. The main characteristic of our stent was the presence of a string tied to the proximal edge of the stent for fixation under the skin of the neck. The first experiment was performedmore » to confirm technical feasibility in three pigs with esophagotracheal fistula. The second experiment was performed to evaluate stent migration and esophagotracheal fistula in three pigs. Results: Creation of the esophagotracheal fistula and stent placement were technically successful in all pigs. In the first experiment, esophagotracheal fistula was sealed by stent placement. In the second experiment, no stent migration was seen 11 or 12 days after stent placement. Gross findings showed no fistulas on the esophageal or tracheal wall. Conclusions: Our new hanging-type esophageal stent seems to offer a feasible method for preventing stent migration.« less

Roux-en-Y gastric bypass (RYGB) is amongst the commonest surgical intervention for weight loss in obese patients. Gastrocutaneous fistula, which usually occurs along the vertical staple line of the pouch, is amongst its most alarming complications. Medical management comprised of wound drainage, nutritional support, acid suppression, and antibiotics may be ineffective in as many as a third of patients with this complication. We present outcomes after endoscopic application of SurgiSIS, which is a novel biomaterial for the treatment of this complication. A case series of 25 patients. Twenty-five patients who had failed conservative medical management of gastrocutaneous fistula after RYGB underwent endoscopic application of SurgiSIS--an acellular fibrogenic matrix biomaterial to help fistula healing. Fistula closure as assessed by upper gastrointestinal imaging and endoscopic examination. In patients who had failed medical management lasting 4-25 (median, 7) weeks, closure of the fistulous tract was successful after one application in six patients (30%), two applications in 11 patients (55%), and three applications in three patients (15%). There were no procedure-related complications. Endoscopic application of SurgiSIS-an acellular fibrogenic matrix--is safe and effective for the treatment of gastrocutaneous fistula after RYGB.

Esophagorespiratory fistulas developing from malignant tumors have serious complications by maintaining continuous airway contamination. The objective was to reveal the incidence, causes and characteristics of fistula formation and to examine the possibilities and efficiency of the treatment. In a single-center study between 1984 and 2004, the data of 2113 patients with tumorous esophageal stenosis were analyzed. Esophagorespiratory fistulas were detected in 264 cases (12.5%). Successful esophageal intubation, stent correction or replacement was performed in 188 cases, while there was one lethal complication. Twenty-seven patients had an intervention for nutritional support: 25 gastrostomies, 1 jejunostomy and 1 percutaneous endoscopic gastrostomy. The mean survival period of all patients was 2.8 months; patients with implanted endoprosthesis 3.4 months; with nutritional support 1.1 months and with only supportive therapy 1.3 months, respectively. The differences between the endoprosthesis implanted group and the other two groups were significant (p<0.001). By sealing the fistula, a successful endoscopic esophageal intubation ends the severe respiratory contamination and the inability to swallow, improving the quality of life and survival period. After the procedure, it is the malignant tumor and not the fistula that determines the future of the patient.

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

Thompson, Mary Jo; Epanomeritakis, Emanuel

An accountable fistula management treatment plan focuses on combining effective medical and nursing treatment with effective and efficient pouching technique and equipment to ensure patient comfort. Small bowel fistula following abdominal surgery can provide challenges in patients' medical and nursing management. This article describes a case study of the successful medical and nursing management of a patient post-abdominal surgery. Within days of surgery a small bowel fistula formed within an abdominal wound. Medical management involved the use of total parenteral nutrition, electrolyte balance management, nil orally and Sandostatin medication. The nursing interventions comprised accurate intake and output measurement, effective and efficient pouching systems and appropriate psychological care. The medical and nursing interventions provided during the healing process are outlined together with the assessment and evaluation of a new innovative wound management pouch. This system proved invaluable in the successful containment of a high small bowel effluent and skin preservation. In an attempt to share best practice a pictorial guide is provided to demonstrate the correct application of the pouching system and technique. This article provides details of an accountable fistula management treatment plan which resulted in the successful spontaneous closure of the small bowel fistula coupled with excellent cost-effectiveness and patient comfort.

Aim of the study is to assess the antimicrobial activity Cassia fistula fruit pulp extracts on some bacterial and fungal strains. Hydro alcohol and chloroform extracts of Cassia fistula fruit pulp were evaluated for the potential antimicrobial activity. The antimicrobial activity was determined in both the extracts using the agar disc diffusion method. Extracts were effective on tested microorganisms. The antibacterial and antifungal activities of solvent extracts (5, 25, 50, 100, 250 μg/mL) of C. fistula were tested against two gram positive, two gram negative human pathogenic bacteria and three fungi, respectively. Crude extracts of C. fistula exhibited moderate to strong activity against most of the bacteria tested. The tested bacterial strains were Staphylococcus aureus, Streptococcus pyogenes, Escherichia coil, Pseudomonas aeruginosa, and fungal strains were Aspergillus. niger, Aspergillus. clavatus, Candida albicans. The antibacterial potential of the extracts were found to be dose dependent. The antibacterial activities of the C. fistula were due to the presence of various secondary metabolites. Hence, these plants can be used to discover bioactive natural products that may serve as leads in the development of new pharmaceuticals research activities. PMID:23049197

Laparoscopic anorectoplasty (LARRP) for the treatment of select anorectal malformations has gained popularity due to enhanced visualization of the fistula and the ability to place the rectum within the sphincter complex while minimizing division of muscles and the perineal incision. However, given the technical challenges and reported complications of ligation, a number of techniques have been described, including using clips, suture ligation, endoloops, or division without closure. We aimed to evaluate fistula closure and division for high imperforate anus using a 5-mm stapler (JustRight Surgical, Boulder, CO). A retrospective chart review was performed on patients who underwent LAARP for imperforate anus between March 2015 and December 2016. Four patients underwent LAARP with division of the fistula using the 5-mm stapler. The average age was 3.2 months and average weight was 4.5 kg. The location of the fistula was rectoprostatic in 3 cases and rectobladder neck in 1 case. There were no complications. Division of a fistula at or above the level of the prostate can safely and effectively be performed with the 5-mm stapler. The stapler allows for division flush with the urethra or bladder ergonomically and quickly.

The aim of this study was to demonstrate the technical feasibility and potential benefits of using a circular mechanical stapler with free jejunal transfer for jejunoesophageal anastomosis in total laryngopharyngectomy reconstruction while comparing the rates of fistula and stricture. This study was a retrospective review of 12 free jejunal flaps completed with circular mechanical stapler for the jejunoesophageal anastomosis with comparison to 17 jejunal free flaps where all anastomoses were hand sewn. In all, 29 patients underwent free jejunal transfer: 12 had jejunal free flap with circular mechanical stapler for jejunoesophageal anastomosis, whereas 17 patients had hand-sewn anastomosis. Corresponding rates of fistula and stricture were 0/12 fistulas and 3/12 strictures in the stapler cohort and 2/17 fistulas with 0/17 strictures in the hand-sewn cohort. No statistically significant difference in rate of fistula was observed between each cohort, whereas a trend toward increased rate of stricture (p = .06) was observed in the stapled anastomosis cohort. Use of circular mechanical stapler appears to be a safe and effective technique at the jejunoesophageal anastomosis for total laryngopharyngeal defects with comparable fistula and stricture rates to grafts that are hand sewn.

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.

Objective: Pemphigus is a rare autoimmune disease that may be fatal without proper medical intervention. It is a blistering disease that involves both the skin and mucus membranes, in which the most important causes of death comprise superimposed opportunistic infections and complications of long-term high-dose corticosteroid therapy or prolonged consumption of immune suppressant drugs. Skin lesions are the most important sources of infection, and any local treatment decreasing the healing time of lesions and reducing the total dosage of drugs is favorable. Materials and Methods: Here, we review the probable mechanism of action of a traditional formulary of Cassia fistula (C. fistula) fruit extract in almond oil as a new topical medication for reducing the duration of treatment of pemphigus vulgaris erosions. Results: C. fistula fruit oil has lupeol, anthraquinone compounds as rhein and flavonoids. Previous in vitro and animal studies on C. fistula fruit have demonstrated wound healing, antioxidative, anti-leukotrienes, anti-inflammatory, antibacterial and antifungal effects of this plant. Conclusion: It is hypothesized that C. fistula L. can be a botanical therapeutic choice for treatment of pemphigus erosions. PMID:28348966

Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure in France. It achieves both adequate excess weight loss and significant reduction in comorbidities. However, fistula is still the most common complication after SG, occurring in more than 3 % of cases, even in specialized centers (Gagner and Buchwald in Surg Obes Relat Dis 10:713-723. doi: 10.1016/j.soard.2014.01.016 , 2014). Its management is not standardized, long, and challenging. We have already reported the short-term results of Roux-en-Y fistulo-jejunostomy (RYFJ) as a salvage procedure in patients with post-SG fistula (Chouillard et al. in Surg Endosc 28:1954-1960 doi: 10.1007/s00464-014-3424-y , 2014). In this study, we analyzed the mid-term results of the RYFJ emphasizing its endoscopic, radiologic, and safety outcome. Between January 2007 and December 2013, we treated 75 patients with post-SG fistula, mainly referred from other centers. Immediate management principles included computerized tomography (CT) scan-guided drainage of collections or surgical peritoneal lavage, nutritional support, and endoscopic stenting. Ultimately, this approach achieved fistula control in nearly two-thirds of the patients. In the remaining third, RYFJ was proposed, eventually leading to fistula control in all cases. The mid-term results (i.e., more than 1 year after surgery) were assessed using anamnesis, clinical evaluation, biology tests, upper digestive tract endoscopy, and IV-enhanced CT scan with contrast upper series. Thirty patients (22 women and 8 men) had RYFJ for post-SG fistula. Mean age was 40 years (range 22-59). Procedures were performed laparoscopically in all but 3 cases (90 %). Three patients (10 %) were lost to follow-up. Mean follow-up period was 22 months (18-90). Mean body mass index (BMI) was 27.4 kg/m(2) (22-41). Endoscopic and radiologic assessment revealed no persistent fistula and no residual collections. Despite the lack of long-term follow-up, RYFJ could be a safe and feasible salvage option for the treatment of patients with post-SG fistula, especially those who failed conservative management. Mid-term outcome analysis confirms that fistula control is durable. Weight loss panel is satisfactory.

To evaluate surgical performance in pancreatoduodenectomy using clinically relevant postoperative pancreatic fistula (CR-POPF) occurrence as a quality indicator. Accurate assessment of surgeon and institutional performance requires (1) standardized definitions for the outcome of interest and (2) a comprehensive risk-adjustment process to control for differences in patient risk. This multinational, retrospective study of 4301 pancreatoduodenectomies involved 55 surgeons at 15 institutions. Risk for CR-POPF was assessed using the previously validated Fistula Risk Score, and pancreatic fistulas were stratified by International Study Group criteria. CR-POPF variability was evaluated and hierarchical regression analysis assessed individual surgeon and institutional performance. There was considerable variability in both CR-POPF risk and occurrence. Factors increasing the risk for CR-POPF development included increasing Fistula Risk Score (odds ratio 1.49 per point, P < 0.00001) and octreotide (odds ratio 3.30, P < 0.00001). When adjusting for risk, performance outliers were identified at the surgeon and institutional levels. Of the top 10 surgeons (≥15 cases) for nonrisk-adjusted performance, only 6 remained in this high-performing category following risk adjustment. This analysis of pancreatic fistulas following pancreatoduodenectomy demonstrates considerable variability in both the risk and occurrence of CR-POPF among surgeons and institutions. Disparities in patient risk between providers reinforce the need for comprehensive, risk-adjusted modeling when assessing performance based on procedure-specific complications. Furthermore, beyond inherent patient risk factors, surgical decision-making influences fistula outcomes.

We present our management of urethral stenosis and rectourinary fistula resulting from prostate cancer therapy. We concentrated on cases refractory to minimally invasive treatment, such as dilation, urethrotomy, and urinary and/or fecal diversion. In our prospectively collected urethral reconstruction database we identified patients who underwent reconstruction of urethral stenosis or rectourinary fistula who also received prior treatment for prostate cancer. We documented demographics, prostate cancer pretreatment characteristics, prostate cancer therapy type, urethral reconstruction type and success. A total of 48 patients met the inclusion criteria, including 16 with rectourinary fistula and 32 with urethral stenosis. Urethral complications followed prior radical prostatectomy, brachytherapy, external beam radiotherapy, cryotherapy, thermal ablation and any combination of these procedures. Stenosis repair was successful in 23 of 32 cases (73%) and it differed little between anterior and posterior urethral stenosis. Repair was accomplished by anastomotic urethroplasty in 19 cases, flap urethroplasty in 2, perineal urethrostomy in 2 and a urethral stent in 9. Prior external beam radiotherapy was a risk factor for urethral reconstruction failure. Fistula repair was successful in 14 of 15 patients (93%), excluding 1 who died postoperatively. The complexity of fistula management was dictated by fistula size and the presence or absence of coincident urethral stenosis. Urethral stenosis or rectourethral fistula following prostate cancer therapy can be managed by urethral reconstruction, such that normal voiding via the urethra is maintained, rather than abandoning the urethral outlet and performing heterotopic diversion. This can be accomplished with an acceptable rate of failure, given the complexity of the cases.

To analyze the management of obstetric vesico-vaginal fistula in the three sites of Engender Health in Guinea. It was a retrospective study of descriptive type having helped collect 450 cases of vesico-vaginal fistulas in three support sites engender health between January 2008 and December 2011. The variables studied were epidemiological, clinical and therapeutic reasons and treatment outcomes were evaluated after a decline of at least six months. The mean age of onset of the fistula was 25years, ranging from 12 to 55years and 58.8% (n=265) of patients were aged between 18 and 30years. The mean duration of fistula was 11years, ranging from 1 to 38years. Eighty-two percent (n=416) of patients were housewives and 66.4% (n=299) off school. The complex fistula with 66% (n=297) was the most frequent. The treatment consisted of a fistulorraphie after splitting vesico-vaginal in 93.3% (n=420) of cases. Therapeutic results considered after a mean of 8months have resulted in a cure in 79.3% (n=357) of cases, improvement in 4.2% (n=19) of cases and failure in 16 4% (n=74) of cases. Vesico-vaginal fistula is a major cause of maternal morbidity in Guinea. The establishment of a real health policy based on sound medical and social structures contributes to its eradication. 5.

Complex fistulas of the duodenum and biliary tree are severe complications of gastric surgery. The association of duodenal and major biliary fistulas occurs rarely and is a major challenge for treatment. They may occur during virtually any kind of operation, but they are more frequent in cases complicated by the presence of difficult duodenal ulcers or cancer, with a mortality rate of up to 35%. Options for treatment are many and range from simple drainage to extended resections and difficult reconstructions. Conservative treatment is the choice for well-drained fistulas, but some cases require reoperation. Very little is known about reoperation techniques and technical selection of the right patients. We present the case of a complex iatrogenic duodenal and biliary fistula. A 42-year-old Caucasian man with a diagnosis of postoperative peritonitis had been operated on 3 days earlier; an antrectomy with a Roux-en-Y reconstruction for stenotic peptic disease was performed. Conservative treatment was attempted with mixed results. Two more operations were required to achieve a definitive resolution of the fistula and related local complications. The decision was made to perform a pancreatoduodenectomy with subsequent reconstruction on a double jejunal loop. The patient did well and was discharged on postoperative day 17. In our experience pancreaticoduodenectomy may be an effective treatment of refractory and complex iatrogenic fistulas involving both the duodenum and the biliary tree.

Laparoscopic Roux-en-Y gastric bypass (RYGB) is the most commonly performed bariatric operation in the United States. Although rare, gastrogastric fistulas are an important complication of this procedure. We report a series of 1,292 consecutive patients who underwent a divided RYGB procedure at our institution between January 2000 and November 2004. Of the 1,292 patients, we identified 15 (1.2%) who presented with gastrogastric fistulas after surgery. The mean age, weight, and body mass index of these patients was 39.5 years, 377.5 lb, and 54.9 kg/m(2), respectively. The mean postoperative follow-up was 17.6 months. The overall follow-up success rate in this series at 1 and 2 years postoperatively was 85% and 77%, respectively. Of the 15 patients, 12 (80%) presented with symptoms of nausea, vomiting, and epigastric pain. Esophagogastroscopy revealed marginal ulcers in 8 (53%) of these symptomatic patients. The most sensitive test for the diagnosis of gastrogastric fistula was an upper gastrointestinal contrast study. The mean time to fistula diagnosis was 80 days. Four patients (27%) had had a known leak before their diagnosis of gastrogastric fistula. In all cases, the leaks were managed nonoperatively with drainage, parenteral nutrition, and bowel rest. In this subset of patients, the mean time to fistula diagnosis was 25 days. Four patients (27%) presented to the clinic unsatisfied with their weight loss. The mean excess percentage of weight loss was 60.9%. Of the 15 patients with a diagnosed gastrogastric fistula, 8 (53.3%) presented with concomitant marginal ulcers. When present, marginal ulcers were managed with chronic acid suppressive therapy consisting of proton pump inhibitors and sucralfate. Revisional surgery was performed in 5 (33.3%) of 15 patients because of the combination of constant pain and ulceration refractory to optimal medical treatment and in 1 patient (7%) because of refractory pain unresponsive to medical therapy and weight regain. All revisional procedures (100%) were performed laparoscopically. Gastrogastric fistulas are an uncommon, but worrisome, complication after divided RYGB. Most symptoms of gastrogastric fistula are related to epigastric pain and ulcerations around the anastomotic site, but the fistula can occur anywhere along the divided segment of the gastric wall. They can initially be managed with a conservative, nonoperative approach as long as the patient remains asymptomatic and weight regain does not occur. Refractory ulcers and pain are the main indications for revisional surgery. Weight loss failure or weight regain is an uncommon short-term finding with gastrogastric fistulas after divided RYGB that requires surgical revision as the definitive treatment option. Although we present one of the largest series to date, longer follow-up is needed to better define the management of this patient population and provide a more accurate incidence of its occurrence.
