Postoperative chylous fistula after neck dissection is an uncommon complication associated with significant patient morbidity. Octreotide acetate is a somatostatin analogue established in the treatment of chylothorax; however, its utility in the management of cervical chylous fistulae has not been fully evaluated. The investigators hypothesized that chylous fistula can be managed by a combination of octreotide and peripheral total parenteral nutrition (TPN). A retrospective review of cases compiled at our institution from 2009 to 2015 was conducted. Ten patients, all men, were identified as having a postoperative chylous fistula after a neck dissection. All patients were treated with peripheral TPN and intravenous octreotide. Mean age of the patients was 63.0 years (range 49 to 82). Five (50.0%) had a neck dissection for the management of metastatic nasopharyngeal carcinoma and had previous neck irradiation. In 8 (80%) patients, chylous fistula occurred in the left neck. Seven (70.0%) of the leaks occurred within the first 2 postoperative days. Eight (80%) leaks were controlled using TPN and octreotide, with 2 (20%) patients requiring surgical intervention. No factors were significant in the successful conservative management of chylous fistulae. One patient with a chylous fistula of 1,800 ml/day was managed successfully without surgical intervention. The results of this case series suggest that chylous fistulae may be managed conservatively with octreotide and TPN. However, long-term evaluation is needed to define if and when surgical intervention is required for control.

Background and Aim: The introduction of mesenchymal stromal cells (MSCs) has changed the management of Crohn's fistula, while it remains controversial. The aim of this study was to provide an overview of efficacy and optimum state of MSCs treatment on Crohn's fistula., Methods: Studies reporting MSCs treatment on Crohn's fistula were searched and included. A fixed-effects model was used to assess the efficacy of MSCs, and outcomes of healing and recurrence were used to evaluate the best states of MSCs intervention., Results: Fourteen articles were enrolled (n = 477). Pooled analysis showed MSCs had a significant efficacy compared to other treatments [risk difference: 0.21 (0.09, 0.32), P = 0.000]. Notably, after MSCs treatment, the group of Crohn's disease activity index (CDAI) baseline >150 group had a higher healing rate (HR) and a clinical response (a change in CDAI of >50 points) (79.17 ± 8.78 vs. 47.54 ± 15.90, P = 0.011) compared to CDAI baseline of <150. The duration time of CD and fistulas had a negative correlation with HR accompanied by MSC therapy (r = -0.900, -0.925). Then, a moderate dose MSCs (2-4 × 10 7  cells/ml) had a higher HR (80.07%) and lower recurrence rate (RR 13.98%) compared to other dosages. Moreover, adipose-derived MSCs therapy had an advantage over bone marrow-derived MSCs in terms of low RR (7.4 ± 4.28 vs. 13.39 ± 0.89)., Conclusions: The evidence supported the effect of MSCs at a more appropriate time of Crohn's fistula. And CDAI baseline (the points >150) has been a candidate for evaluating effectiveness of MSCs application on Crohn's fistula.

Background and Study Aims: Post-lobectomy bronchopleural fistula is a rare complication of lung resection surgery, and proper management is crucial for the successful resolution. Most published papers deal with surgical treatment. We report our experience with a new interventional management, endobronchial naso-bronchial lavage (ENBL). The aim of this study was to evaluate the continuing efficacy and safety of this innovative procedure., Patients and Methods: From 2002 to 2012, 17 patients who suffered from post-lobectomy bronchopleural fistula were recruited. An ENBL tube was inserted form nostril through the trachea, bronchus and the fistula into the pleural cavity with bronchoscope. Lavage of the pleural cavity was proceeded form the ENBL tube and drained form thoracostomy drainage tube. All patients were followed up for at least 6 months., Result: All patients received total recovery from the post-lobectomy bronchopleural fistula. The ENBL procedure could be finished in 10-15 min. No blooding without control, pneumonia or damage of trachea associated with this procedure occurred. With an at least 6 months' follow-up of the patients, no further intervention was performed., Conclusions: It suggested that the ENBL may be an alternative interventional treatment for bronchopleural fistula treating other than surgical procedure.

A 52-year-old man was referred to our hospital complaining of right lower abdominal pain. He was diagnosed with appendicitis complicated with a liver abscess and underwent an appendectomy. After antibiotic treatment following surgery, the liver abscess penetrated the right lung, which was considered to be drained from a hepatobronchial fistula. Due to the effect of drainage, the liver abscess immediately improved and the patient was subsequently discharged.

Objective: To assess an alternative to bed rest and surgery for suspected perilymphatic fistulas using intratympanic blood injections., Method: A review was conducted of patients' history, physical and audiometric data, before and after treatment by intratympanic blood injections performed from 2009 to 2015., Results: Twelve ears were identified, with trauma associated with air travel, water sports or nose blowing. Ten of these cases had hearing loss, six had vestibular symptoms. Four cases had audiological and vestibular symptoms, two had vestibular symptoms only, and six had audiological symptoms only. Time-to-treat varied from 1 day to 30 days. Magnetic resonance imaging scans were obtained for five cases. Ten cases received steroids. Six out of seven cases showed improvement of hearing loss. Five cases showed positive fistula test results, four with documented resolution. Seven cases had full resolution of all symptoms, four had near-full resolution and one had no improvement., Conclusion: Intratympanic blood injections offer an effective alternative to conservative or surgical therapy. Advantages include sooner time-to-treat, lower financial costs and decreased psychosocial burdens. It allows a more flexible and liberal use of a potential definite treatment for perilymphatic fistula.

Stem cells represent heterogeneous population of undifferentiated cells with unique characteristics of long term self renewal and plasticity. Moreover, they are capable of active migration to diseased tissues, secretion of different bioactive molecules, and they have immunosuppressive potential as well. They occur in all tissues through life and are involved in process of embryogenesis and regeneration. During last decades stem cells attracted significant attention in each field of medicine, including plastic and reconstructive surgery. The main goal of the present review article is to present and discuss the potential of stem cells and to provide information about their safe utilization in chronic wounds and fistulae healing, scar management, breast reconstruction, as well as in bone, tendon and peripheral nerve regeneration.

Objectives: After tuberculous pleurisy, lymphadenitis arising from cervical lesion is the second most common form of extrapulmonary tuberculosis. It is generally treated with antituberculosis agents, but some patients resist chemotherapy. In such cases, surgical resection is often considered as an alternative treatment. This study aims to evaluate the therapeutic outcome of cervical tuberculous lymphadenitis and the future course of treatment of this disease., Methods: We retrospectively reviewed the clinical charts of patients diagnosed at the Tokyo Metropolitan Tama Medical Center between 2009 and 2015 and identified 38 cases of cervical tuberculous lymphadenitis. Precisely 798 patients were registered for primary tuberculosis at our institution during the same period., Results: Patient ages ranged from 21 to 85 years (average: 58.9 years), and the male-to-female ratio was 1:1.2. The range of tuberculosis progression was as follows: 30 (78.9%) in only the cervical lymph node, 3 in the other (axillary, mediastinal, and abdominal) lymph nodes, 1 in the lung and vertebrae lumbales, 2 in the lung, and 1 in the pleural membrane. All 38 patients were initially treated with antituberculous drugs at the Department of Pulmonary Medicine based on guidelines for tuberculosis cases in Japan. In seven cases, the antituberculous drugs were replaced due to side effects. Four cases involved a single drug-resistant strain, and one case involved a double drug-resistant strain. Thirty-three (86.8%) cases were cured by chemotherapy alone. The three patients resistant to chemotherapy were successfully treated through neck dissection. Thirty-six cases (94.7%) were cured by chemotherapy or chemotherapy and surgery., Conclusion: Local therapy could prove effective in cervical tuberculous lymphadenitis patients who exhibit an inadequate response to drugs. The role of neck dissection in cervical tuberculous lymphadenitis remains an important consideration., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

The aim of the study is to examine the utilization of hyperbaric oxygen treatment (HBOT) as an alternative to surgical treatment for non-healing postoperative phayngocutaneous fistula (POPCF). A retrospective study was conducted between 2012 and 2014 of referred patients who had failed conservative treatment for POPCF at other medical centers. Reevaluation at our department was followed by therapeutic management including daily HBOT. Eight male patients with a mean age of 62.3 years were included. The average period of conservative treatment was 1 month before admittance to our department. All patients were managed with HBOT and local debridement. Closure of the POPCF was proved by a barium swallow test in seven patients (87.5 %). HBOT is recommended for patients who have failed conservative treatment for POPCF post-laryngectomy, due to a high rate of successful (87.5 %) closure and should be considered as an alternative to surgical treatment.

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., Competing Interests: Conflicts of Interest: None declared

Aim: Bone osteoradionecrosis is a serious complication of radiation treatment. Current treatment approaches are not curative and treatment response is often poor leading to high social and healthcare costs., Case Report: We report on the first case of osteoradionecrosis with successful restitutio ab integro by repeated administration of platelet gel (PLT-gel) and surgery in a critically ill patient. The administration of PLT-gel during a severe septic episode helped regeneration of bone and soft tissues, shortening the hospital stay of the patient. It was also noted that following applications of PLT-gel, both the use of morphine and the numbers of infective episodes were reduced., Conclusion: Additional studies are needed to confirm the promising effect of PLT-gel for the treatment of osteoradionecrosis.

OBJECTIVE In most patients with spontaneous intracranial hypotension, a spinal CSF leak can be found, but occasionally, no leak can be demonstrated despite extensive spinal imaging. Failure to localize a CSF leak limits treatment options. The authors recently reported the discovery of CSF-venous fistulas in patients with spontaneous intracranial hypotension and now report on the use of digital subtraction myelography in patients with spontaneous intracranial hypotension but no CSF leak identifiable on conventional spinal imaging (i.e., non-digital subtraction myelography). METHODS The patient population consisted of 53 consecutive patients with spontaneous intracranial hypotension who underwent digital subtraction myelography but in whom no spinal CSF leak (i.e., presence of extradural CSF) was identifiable on conventional spinal imaging. RESULTS The mean age of the 33 women and 20 men was 53.4 years (range 29-71 years). A CSF-venous fistula was demonstrated in 10 (19%) of the 53 patients. A CSF-venous fistula was found in 9 (27%) of the 33 women and in 1 (5%) of the 20 men (p = 0.0697). One patient was treated successfully with percutaneous injection of fibrin sealant. Nine patients underwent surgery for the fistula. Surgery resulted in complete resolution of symptoms in 8 patients (follow-up 7-25 months), and in 1 patient, symptoms recurred after 4 months. CONCLUSIONS In this study, the authors found a CSF-venous fistula in approximately one-fifth of the patients with recalcitrant spontaneous intracranial hypotension but no CSF leak identifiable on conventional spinal imaging. The authors suggest that digital subtraction myelography be considered in this patient population.

Objective: Tarlov cyst is an abnormal expansion of the spinal nerve sleeve, and it communicates with the subarachnoid cavity via a perineural fistula. This study presents our experience of a balloon-assisted fistula sealing procedure in treating Tarlov cyst., Methods: Twenty-two patients with symptomatic Tarlov cysts were surgically treated. An emulsion balloon was placed into the lumbar subarachnoid cistern through a trocar, so as to temporarily block cerebrospinal fluid flow, then the thecal sac was opened and the inlet of the fistula was sealed by suture of a muscular patch and reinforced by fibrin glue. Finally, the cyst wall was imbricated and the bony cavity was filled with pedicled muscle flaps., Results: Comparing the preoperative and postoperative pain scores according to visual analog scale, 2 patients were slightly improved and 18 patients were substantially improved, including 3 completely pain-free cases. Only 2 patients were unchanged in pain, and both of them had multiple cysts. As a whole, the postoperative pain score was much better than the preoperative score (2.4 vs. 7.5; P < 0.01). Bladder weakness was slightly improved, and bowel dysfunction was almost unchanged after operation. During follow-up, cyst recurrence was found in 1 patient., Conclusions: The balloon-assisted fistula sealing procedure is safe and effective for Tarlov cyst, especially for the single cyst. It is a good complement to the cyst wall imbricating procedure., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Introduction: 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., Methods: 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., Results: 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., Conclusion: 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.

Cell sheet technology opens new perspectives in tissue regeneration therapy by providing readily implantable, scaffold-free 3D tissue constructs. Many studies have focused on the therapeutic effects of cell sheet implantation while relatively little attention has concerned the fate of the implanted cells in vivo. The aim of the present study was to track longitudinally the cells implanted in the cell sheets in vivo in target tissues. To this end we (i) endowed bone marrow-derived mesenchymal stem cells (BMMSCs) with imaging properties by double labeling with fluorescent and magnetic tracers, (ii) applied BMMSC cell sheets to a digestive fistula model in mice, (iii) tracked the BMMSC fate in vivo by MRI and probe-based confocal laser endomicroscopy (pCLE), and (iv) quantified healing of the fistula. We show that image-guided longitudinal follow-up can document both the fate of the cell sheet-derived BMMSCs and their healing capacity. Moreover, our theranostic approach informs on the mechanism of action, either directly by integration of cell sheet-derived BMMSCs into the host tissue or indirectly through the release of signaling molecules in the host tissue. Multimodal imaging and clinical evaluation converged to attest that cell sheet grafting resulted in minimal clinical inflammation, improved fistula healing, reduced tissue fibrosis and enhanced microvasculature density. At the molecular level, cell sheet transplantation induced an increase in the expression of anti-inflammatory cytokines (TGF-ß2 and IL-10) and host intestinal growth factors involved in tissue repair (EGF and VEGF). Multimodal imaging is useful for tracking cell sheets and for noninvasive follow-up of their regenerative properties.

Pelvic lymphoceles/lymph fistulas are commonly observed after kidney allotransplantation, especially when the kidney is placed in a retroperitoneal position. While the majority are <5 cm in diameter and resolve without intervention, some may continue to enlarge, and cause local or systemic symptoms or graft dysfunction. Among 1662 recipients of both living and deceased donor kidney transplants between January 2003 and July 2014, we found 46 (2.7%) patients with symptomatic lymphoceles requiring intervention. We studied the clinical outcomes and charges for three treatment modalities including open surgical drainage (22), laparoscopic surgical drainage (11), and percutaneous fibrin glue injections into the drained lymphocele cavity (13). The patient demographics and clinical characteristics were comparable for each treatment group, although maintenance immunosuppressive drugs differed by era. We found fibrin glue injections resulted in significantly lower (p = 0.04) rates of recurrence (1; 7.7%) than either laparoscopic (6; 54%) or open surgical drainage (6; 27.3%). In addition, fibrin glue injections generated significantly (p < 0.001) lower median ($4559) charges compared to either laparoscopic ($26,330) or open surgical drainage ($23,758). Fibrin glue treatment has the advantage of being an outpatient procedure, performed with the patient under local anesthesia, and does not incur the expense of an operative procedure or hospital admission associated with laparoscopic or open surgery., (© Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.)

The coronary fistula is a link between one or more of the coronary arteries and cardiac cavity or great vessel. The exact occurrence is unknown. The majority of these fistulas are congenital in origin. However, they may occasionally be detected after cardiac surgery. For a long time, fistulas are asymptomatic, especially if they are small; the frequency of the symptoms and especially the complications rise with age. The potential complications are: cardiac failure, endocarditis, endarteritis, atrial fibrillation, ventricular arrhythmias, rupture, and thrombosis. The main differential diagnosis is patent arterial duct, while other congenital arteriovenous shunts need to be excluded. Even though echocardiography Doppler can help to differentiate shunts, the coronary angiography remains the main diagnostic tool for the description of the anatomy. For a long time, the surgery was the only therapeutic means, up till now, percutaneous occlusion is the first line therapy of coronary fistulas and that the different devices can be tailored to meet different anatomic and functional characteristics., (Copyright © 2013 Elsevier Masson SAS.

Background: Dialysate leakage into the pericardium is a rare but potentially life-threatening complication of peritoneal dialysis (PD). There has been one reported pediatric case of spontaneous peritoneo-pericardial fistula in a 2-year-old boy with tissue fragility due to malnutrition and two reported adult cases in PD patients with a history of previous cardiac surgery and/or pericardiocentesis., Case-Diagnosis/treatment: We describe a 15-year-old girl with end-stage renal disease secondary to granulomatosis with polyangiitis, with recurrent pericardial effusions secondary to a peritoneo-pericardial fistula while on continuous cycling peritoneal dialysis (CCPD). She had previously presented with chylous pericardial effusion that required pericardiocentesis and subsequently developed recurrent pericardial effusions when she was commenced on CCPD 9 months later. Pericardial fluid chemistry revealed a sterile, serous fluid containing 15.1 mmol/L of glucose and <0.11 mmol/L of triglycerides. Peritoneal scintigraphy with Tc-99m labeled sulfur colloid injected intra-peritoneally confirmed the presence of a peritoneo-pericardial fistula. The pericardial effusions resolved upon switching the patient to hemodialysis (HD)., Conclusions: Our case of recurrent pericardial effusions in a child on PD secondary to a peritoneo-pericardial fistula highlights the need for close follow-up in patients with a history of previous pericardiocentesis who are commenced on PD.

Purpose: Peripheral bronchopleural fistulas (BPF) are communications between a peripheral bronchus or the lung parenchyma and the pleural space. Although reported cases with peripheral BPF might have typical symptoms, we postulate that there may be BPF patients without typical symptoms who are diagnosed on computed tomography (CT) for the first time., Materials and Methods: We searched retrospectively for how frequently BPF is found on CT in cases with known or suspected empyema or hydropneumothorax. Also, we examined the clinical charts to ascertain if a diagnosis of BPF was suspected in the CT reports or clinically, and to determine the outcome of each case., Results: Thirteen thoracic cavities of 12 patients were included in this study. Of these, BPF was suspected clinically in only 1. Mention in the CT report about the presence of BPF was found in 2 cases. An apparent finding of BPF on CT was found in 7 of 13 (53%) thoracic cavities of 6 cases. The outcomes were that 1 patient died 1 month later due to multiple organ failure, and 1 patient was discharged subsequently after CT. In the other 10 cases, there was no exacerbation of the symptom regardless of definite evidence of BPF on CT., Conclusions: In conclusion, when there is hydropneumothorax on CT, it is important for radiologists to diligently search for findings of peripheral BPF and to document it. However, a reference about the need for a surgical approach for BPF may not be required.

Surgery, the usual treatment option for vesicouterine fistula (VUF), is often delayed to allow involution of the uterus. The authors report a case of successful treatment with urinary catheterization. A 39-year-old, gravida 7, para 6, woman presented at term with obstructed labor. She had one previous cesarean section followed by a vaginal birth before. She underwent emergency cesarean section. She was readmitted after one week because of pelvic collection. Aspiration revealed pus and urine. Retrograde cystogram and pelvic MRI confirmed the presence of VHF. Urinary bladder catheterization for six weeks resulted in the successful treatment of the fistula. Urinary catheterization in the early postpartum period can result in resolution of post-cesarean section VUF, without delaying surgical intervention if it becomes necessary.

Pyriform sinus fistula is a rare branchial pouch anomaly, which causes recurrent neck abscess. Although complete excision of the fistula tract is considered as a definitive treatment for pyriform sinus fistula, it has been suggested that chemocauterization with trichloroacetic acid (TCA) of the internal opening is a reasonable treatment. For this purpose identifying the existence of an internal opening is important. Here, we describe the Modified Killian's method, a recently proposed simple endoscopic technique to observe a wider area of the hypopharyngeal space, and show that it is helpful to identify the internal opening of the pyriform sinus fistula. The Modified Killian's method is a suitable examination for pyriform sinus fistula prior to TCA chemocauterization., (Copyright © 2016 Elsevier Inc. All rights reserved.)

We report two cases of bilothorax that occurred as a complication of percutaneous transhepatic biliary drainage. In an 86-year-old woman who had undergone percutaneous transhepatic biliary drainage for obstructive jaundice, bilothorax occurred after accidental removal of the tube. She recovered with chest drainage only. An 83-year-old man who had undergone percutaneous transhepatic biliary drainage for cholecystitis developed bilothorax with infection. He recovered with thoracoscopic curettage. Although bilothorax is a rare complication of percutaneous transhepatic biliary drainage, appropriate diagnosis and prompt treatment is important, especially when bilothorax is accompanied by infection., (© The Author(s) 2015.)

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

Background: Chylous leakage is a relevant clinical problem after major abdominal surgery leading to an increased length of stay., Data Sources: A systematic search of MEDLINE/PubMed and the Cochrane Library was performed according to the PRISMA statement. The search for the MeSH terms "chylous ascites" and/or "lymphatic fistula" retrieved a total of 2,348 articles, of which 36 full-text articles were reviewed by 2 independent investigators., Results: Chylous ascites is described with an incidence of up to 11%, especially after pancreatic surgery. The incidence is increasing with the number of lymph nodes harvested. In patients treated with total parenteral nutrition, conservative treatment is demonstrated to be effective in up to 100% of cases., Conclusions: The extent of abdominal surgery mainly predicts the risk of chylous ascites. Conservative treatment has been shown to be effective in almost all cases and is the treatment of choice., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Parotid fistula is a rare complication of surgical or non-surgical trauma on or in the vicinity of parotid gland. Many pharmacological agents and surgical methods are used to treat it with their own merits, demerits and patient preferences. Injection of hypertonic hot saline along with compression dressing is an economical, patient-preferred and almost complication-free method to deal parotid fistula with promising results.

Objective: Cervical chylous fistula is an uncommon complication after neck dissection, but it might lead to some serious clinical outcomes. Although most cervical chylous fistulas can heal in a few days with standard treatments, some can be intractable. In this study, we describe a new method with local application of Pseudomonas aeruginosa injection for intractable cervical chylous fistula., Study Design: Case series with chart review., Setting: West China Hospital, Sichuan University, Chengdu, China., Subjects and Methods: The charts of 18 patients who were treated with P aeruginosa injection (PAI) for intractable cervical chylous fistula were retrospectively reviewed., Results: All patients were successfully treated with PAI. Mild fever (temperature, <38°C) occurred in 9 patients, moderate fever (38°C-39°C) in 4 patients, and severe fever (>39°C) in 5 patients. All patients had mild to severe neck pain., Conclusions: Local application of PAI is an effective method for the treatment of intractable cervical chylous fistula, of which the most common side effects are transient fever and local pain., (© American Academy of Otolaryngology-Head and Neck Surgery Foundation 2015.)

A 47-year-old woman presented to a tertiary emergency department with an 8-day history of odynophagia, a 4 cm swelling on her left neck and intermittent fevers. Shortly following her birth, a congenital oesophageal atresia had been managed surgically with colonic interposition graft. Contrast CT of the neck demonstrated several large diverticula within her interposition graft at the level of the cervical vertebrae. A colocutaneous fistula was identified between the colon and left neck, with an associated abscess. The patient received intravenous meropenem followed by abscess drainage. A high output fistula developed at the drainage site, and the patient required intravenous fluids and stoma placement to manage fluid discharge. She left the hospital after a 17-day stay. At 6-month follow-up, the wound was erythematous, but the patient was otherwise well. We believe that this is the first reported case of diverticular disease arising in what was originally neonatal colon interposed for oesophageal atresia at birth., (2015 BMJ Publishing Group Ltd.)

Background: Endoscopic management of post-bariatric surgery leaks using self-expandable metal stents (SEMSs) is an alternative to revisional surgery. We evaluated the effectiveness of a standardized protocol for management of post-bariatric surgery leaks in a large cohort of patients., Methods: Data from patients with anastomotic leaks after bariatric surgery endoscopically treated with partially covered SEMS in our institution between January 2006 and December 2012 were retrospectively reviewed. Patients were divided into four categories: (1) healing of fistula after only one SEMS, (2) healing of fistula after multiple SEMSs and/or additional therapy, (3) healing of fistula after salvage endoscopic procedure despite SEMS failure, and (4) SEMS and endoscopic failure for fistula healing., Results: Ninety-one patients (median age 42 years; 33 males) were considered suitable for inclusion. Our standardized stenting policy was successful in 74 patients (81 %). Among the 17 patients with SEMS failure, 6 patients were ultimately healed by internal drainage of the leakage (7 %). Endoscopic treatment failed in 11 patients (12 %). In univariate analysis, male gender (p = 0.024), higher prebariatric surgery BMI (p = 0.025), and shorter delay between surgery and SEMS placement (p = 0.011) were more frequently observed in the one-step treatment group (group 1) as compared to the other groups. In multivariate analysis, gender (p = 0.035) and delay between surgery and SEMS placement (p = 0.042) were independent predictive factors of endoscopic success., Conclusions: Endoscopic management using SEMS for anastomotic leaks after bariatric surgery is effective and may avoid risky surgical reintervention in 81 % of patients. Early stenting was a major significant factor associated with increased success.

A patient with a history of rheumatic mitral valve disease and valve replacement in childhood presented with severe, persistent dyspnea. During an electrophyisiologic procedure, she was discovered to have a fistula from the left ventricle to the coronary sinus. She had severe pulmonary hypertension and elevated filling pressures, with a significant left-to-right shunt. Percutaneous closure of the fistula was performed using two vascular plugs. Subsequently the patient's hemodynamics improved and her symptoms subsided. Here, we describe the case and review the literature., (© 2014 Wiley Periodicals, Inc.)

Objective: To study the clinical usefulness of ultrasound-guided alcohol sclerosis as a treatment alternative to surgical intervention for breast fistulas., Material and Methods: This was a retrospective study of data collected in a hospital breast unit over a three-year period (January 2011 through December 2013). The procedure consists of introducing a sclerosing solution into the lumen of the breast fistula under ultrasound guidance. All cases were reviewed by a multidisciplinary committee; patients were offered ultrasound-guided alcohol sclerosis as a first treatment option with surgical intervention as a rescue therapy for those with unsatisfactory outcomes., Results: Ten fistulas were treated in 9 women (median age, 33 y; interquartile range 18.5 y). Five patients (50%) attributed the clinical findings to recurrent mastitis, four (40%) to a previous surgical intervention, and one (10%) to lactation. Seven patients (78%) were smokers. The procedure was well tolerated: nine patients (90%) rated the pain as one or 2 (mild pain) on a visual analogue scale. There were no immediate complications. The response to treatment was considered excellent (absence of secretion and complete closure) in eight fistulas (80%)., Conclusion: Ultrasound-guided alcohol sclerosis achieved excellent outcomes in 80% of cases and is a viable alternative to surgical treatment., (Copyright © 2014 SERAM.

Congenital median dermoid is an uncommon disease. Surgery is the main curative treatment. To review a clinical case and to summarise the characteristics and treatment experience of this disease, referring to the related literature, it is expected that we can provide more clinical thought and therapeutic method for congenital median dermoid fistula of nasal dorsum.

A previous phase II clinical trial of adipose-derived stem cell (ASC) therapy for fistulae associated with Crohn's disease, a devastating condition with a high recurrence rate, demonstrated safety and therapeutic potential with a 1-year sustained response. In the present study, 41 of the 43 phase II trial patients were followed for an additional year, regardless of response in the initial year. At 24 months, complete healing was observed in 21 of 26 patients (80.8%) in modified per protocol analysis and 27 of 36 patients (75.0%) in modified intention-to-treat analysis. No adverse events related to ASC administration were observed. Furthermore, complete closure after initial treatment was well-sustained. These results strongly suggest that autologous ASCs may be a novel treatment option for Crohn's fistulae., (©AlphaMed Press.)

We report on a 6-year-old boy with a huge right coronary artery to the right ventricle fistula, who had previously been treated by device closure at the right ventricular exit point. However, 3 years later, the right coronary artery aneurysm showed progressively dilation and compressed the right ventricle. To prevent further complications related to the aneurysm, the proximal part of the aneurysm was successfully occluded by a vascular plug.

A 87-year-old man received radical nephroureterectomy for right renal pelvic cancer in 2009 and left cutaneous ureterostomy after radical cystectomy for bladder cancer in 2013. He visited the hospital for exchanging a 7 or 8 Fr single-J catheter every 2 to 4 weeks. Eleven months after the 2nd operation, massive bleeding from the stoma occurred when ureteral catheter was exchanged. Contrast-enhanced computed tomography showed that left inferior epigastric artery was located close to left ureter. Angiography of the left inferior epigastric artery didn't show an obvious fistula, but revealed the stoma was surrounded by ramified new blood vessels from left inferior epigastric artery. We suspected a rupture of the vessels and performed embolization for the branch of inferior epigastric artery to left ureter. This embolization made it possible for the bleeding to be controlled. Massive bleeding from the branch of inferior epigastric artery is very rare, and we report the case and review the literature.

Background: We evaluated the effectiveness and safety of prophylactic PEG performed for the enteral nutrition support during the oncological treatment of patients with HNCs and as a part of the management of neurological patients experiencing neurogenic dysphagia., Methods: In 2013 we followed up on a group of 23 HNC patients subjected to prophylactic PEG. We assessed the duration of the procedure, intraprocedural incidents and their causes, time to tube-refeeding and discharge after intervention, post interventional analgesia, early and late complications,toleration, costs and postoperative course of these patients after radical surgery maintaining PEG in place. In parallel we followed up on a group of 10 neurological patients who have undergone a PEG placement to improve the nutrional status and to prevent recurrent chest infections due to ND related silent aspiration., Results: The procedures were performed under sedation with Midazolam and the mean duration was about 7 minutes.Postoperative analgesia was minimal. Refeeding through the tube was initiated 2-4h hours later and the patients were discharged 12-24h after the procedure. Early complications were not observed and later we noted 2 cases of peristomal infections, succesfully managed conservatively. After oncologic surgery we noted 2 (8.69%) pharyngocutaneous fistulas.Conservative care obliterated the fistulas at 6 weeks, maintaining the feeding tube in place. We also compared the results with a group of 27 patients fed through the naso-gastric tube and a group of 20 cases with open gastrotomy-tube prophylactically inserted. The 10 neurological patients had varied conditions but degenerative diseases like motor neuron disease (3 cases" 30%) and multiple sclerosis (2 cases -20%) took the lead we encountered one case of peristomal infection and one case of tube blockage resolved by replacement. We evaluated the nutritional status by controling the weight of these patients before and after PEG placement. A mean weight gain of 3.1 kg(range 1.2 â€" 7) was documented., Conclusions: PEG is a simple minimmaly invasive procedure performed safely under sedation. It takes a very short time and is virtually free of major complications. The requirements of analgesics are minimal. The refeeding is started early and the tube is well tolerated by the patient. PEG has an important role in the conservative healing of pharyngocutaneous fistula.PEG is the procedure of choice for the neurological patients.It prevents weight loss and aspiration pneumonia in patients with neurogenic dysphagia with a low rate of complications., (Celsius.)

Objectives: To determine the effectiveness of platelet-rich plasma (PRP) in the treatment of nonhealing fistula in spinal cord-injured patients., Study Design: This was a pilot study of 15 spinal cord-injured patients with chronic pressure ulcers (PrUs) and nonhealing fistulas treated with PRP., Setting: Germany, Rheinland Pfalz, BG Trauma Center Ludwigshafen, Methods: The authors treated 15 patients with PRP who had nonhealing fistulas due to multiple surgical closures of PrUs. According to the National Pressure Ulcer Advisory Panel's stages, 12 patients had Stage III PrUs, and 3 patients had Stage IV PrUs., Results: After 1 week of treatment with PRP, the authors observed low levels of secretion from the fistulas. After 2 weeks, they noted no further secretion from the fistulas. A magnetic resonance imaging control investigation after 3 weeks showed the complete disappearance of the fistulas. No negative effects and no allergic reactions were noted in the use of PRP., Conclusion: The authors' results suggest that the application of PRP in combination with debridement is an effective therapy option and good alternative to recurrent surgical interventions for treating nonhealing fistulas resulting from the surgical closure of PrUs.
