Late-Onset Chronic Corneal Fistula Following Phototherapeutic Keratectomy: A Case Report and Importance of Early Detection.

BACKGROUND We report a case of late-onset chronic fistula in a decompensated cornea after multiple ocular surgeries and a recent phototherapeutic keratectomy (PTK). CASE REPORT A 73-year-old woman presented to our service with a past ocular history of bilateral chronic angle closure glaucoma and pseudophakic bullous keratopathy in the left eye. Given a history of long-term uncontrolled glaucoma with advanced disc cupping and poor visual potential, the patient underwent multiple palliative procedures, including, most recently, a PTK. Few years later she presented with a spontaneous late onset of slowly appearing corneal leak on fluorescein staining upon routine clinical examination. Corrected distance visual acuity was hand motion and intraocular pressure (IOP) was 40 mmHg in the affected eye. Serial anterior segment optical coherence tomography (AS-OCT) sections were obtained, which aided in understanding the current presentation and revealed distinctive multilayer corneal changes during the healing process. The patient was successfully managed with cyanoacrylate corneal gluing and ocular hypotensive medications, which halted the corneal leak. CONCLUSIONS We report a case of a rare finding of corneal fistula in an eye with multiple previous ocular surgeries, and provide an explanation of the possible etiopathogenesis. We also highlight the pivotal role of AS-OCT for evaluating such cases and stress the importance of early detection of similar subtle leaks in the setting of a formed anterior chamber, which can often be missed, carrying a risk of infection.

Conservative management of postoperative chylous fistula with octreotide and peripheral total parenteral nutrition.

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.

Contact-Force Catheters: Efficacy Versus Safety? Case Report of 2 Atrioesophageal Fistulae.

Contact-force (CF) catheters appear to be more effective compared to standard ablation catheters for complex radiofrequency ablation including atrial fibrillation (AF) ablation when optimal CF >10 g is achieved. Some have suggested that this technology could also improve procedural safety. We report 2 cases of atrioesophageal fistulae (AEF), a rare but catastrophic complication of AF ablation. These are to our knowledge the first cases of AEF described after using CF catheters.

Use of autologous platelet-rich plasma in complete cleft palate repair.

OBJECTIVES/HYPOTHESIS: 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. STUDY DESIGN: Case control study. METHODS: 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. RESULTS: 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. CONCLUSION: 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. LEVEL OF EVIDENCE: 3b. Laryngoscope, 126:1524-1528, 2016.

Novel and Effective Almagate Enema for Hemorrhagic Chronic Radiation Proctitis and Risk Factors for Fistula Development.

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

Hyperbaric oxygen therapy as an alternative to surgery for non-healing pharyngocutaneous fistula.

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.

[Pneumoperitoneum after jacuzzi bathing -- an unusual cause for the development of intraperitoneal free air]. / Jacuzzihasználatot követoen kialakult pneumoperitoneum, avagy a szabad hasi levego keletkezésének ritka esete.

Free air within the intraperitoneal cavity most frequently occurs in conjunction with perforation of a hollow viscus and requires urgent surgical intervention. However, approximately 10% of all cases of pneumoperitoneum may not be correlated with disruption of the gastroinestinal tract. In the literature this condition is termed "nonsurgical" (NS) pneumoperitoneum and usually requires conservative management. NS pneumoperitoneum can be classified into the following categories: abdominal, thoracic, gynecologic, and idiopathic. We present a rare case of NS pneumoperitoneum. A 61-year-old woman who underwent a hysterectomy previously is admitted with diffuse abdominal pain without any other symptoms. Chest and abdominal radiographs verified the presence of free air under the diaphragm. We performed an exploration but no evidence of perforated viscus or peritonitis was found. Finally the patient told us that her complaints developed during Jacuzzi usage. We thought therefore that air entered into the intraperitoneal cavity through the vagina by influence of high pressure douche. In the course of postoperative gynecological examination a vaginoperitoneal fistula was detected in the vault which is developed during Jacuzzi usage leading to NS pneumoperitoneum. Essentially, NS pneumoperitoneum usually occurs without signs and symptoms of peritonitis and requires conservative treatment. Detailed physical examination and medical history taking can help to avoid unnecessary surgery in spite of radiological evidence of intraperitoneal free air.

Long-term antibiotic therapy in late onset pouch-urethral fistula after ileoanal anastomosis for ulcerative colitis may be effective and well tolerated.

A 25-year-old male patient underwent restorative proctocolectomy and ileoanal anastomosis in 1991 for refractory ulcerative colitis. In February 2001, he presented with pneumaturia, faecaluria, pelvic 'pressure' and watery diarrhoea caused by passage of urine through the anal canal. A fistula between the pouch and the membranous urethra was demonstrated by a pouchogram contrast study. In October 2002, he was started on ciprofloxacin 250 mg once daily and metronidazole 400 mg twice daily. Apart from a short break in 2003 the patient has remained on this regimen until the time of writing (now over 10 years) and has had sustained remission, excellent quality of life and no adverse effects.

Treatment of lymphocutaneous fistulas after vascular procedures of the lower limb: accurate wound reclosure and 3 weeks of consistent and continuing drainage.

BACKGROUND: Lymphocutaneous fistulas occurring after vascular procedures of the lower limb are a rare, but frustrating, complication. Many treatment options exist, but may lead to inconsistent results, with infection, delayed wound healing, and prolonged hospital stay. We present a simple surgical treatment of wound closure and drainage. METHODS: In this single-center, single-intervention, observational clinical study (case series), prospectively collected data of 23 consecutive lymphocutaneous fistulas in 22 patients (19 male and three female; age, 42 to 91 years) treated between June 2005 and October 2008 were retrospectively analyzed. Twenty-two fistulas were situated in the groin and one at the knee incision. The standardized therapy consisted of the installation of a Redon to drain the lymph, and accurate closure of the wound. Postoperatively, drainage was maintained for 21 days: suction Redon drainage for the first 7 days, passive Redon drainage for the next 7 days, and further drainage in a pouch after removal of the drain for the last 7 days. RESULTS: In 19 of the initial 23 lymphocutaneous fistulas, the whole drainage procedure was completed, with healing of the wound, without infection, recurrence, or lymphocele formation after 1 year of follow-up. In these cases, there had been a steady decrease of daily lymph drainage: a mean of 163.4 (standard error on the mean, 39.6) mL on the first day of suction, 56.8 (15.5) mL on the first day of passive drainage, 11.6 (4.3) mL on the last day of passive drainage, and 2.1 (0.9) mL on the 21st day when the drainage treatment was stopped. In four fistulas, this treatment was considered a failure because of inadvertent early drain removal (two cases), infection (one case), and lymphorrhea recurrence with wound breakdown (one case). CONCLUSION: This standardized surgical therapy, consisting of accurate wound closure and 3 weeks of drainage, allowed the healing of 19 of 23 postoperative lymphocutaneous fistulas (an 82.6 % success rate), without infection, recurrence, or lymphocele formation after 1 year of follow up.

Pharyngoesophageal junction neoplasia--therapeutic management.

Not only the anatomy but the treatment and the prognosis of these tumors are intermediate between hypopharyngeal and esophageal tumors. After a portion of the esophagus is removed or complete esophagectomy, a conduit must be established. The authors reviewed the experience of Prof. Cristian Popescu in total pharyngo-laryngectomy and his technique of pharyngoesophageal reconstruction with synthetic esophageal prosthesis. We have some 21 patients who underwent an esophageal reconstruction with Montgomery esophageal tube. This is a very important new, modem, interdisciplinary approach bewteen the head and neck surgeon and the general/thoracic surgeon to treat the pharyngo-laryngo-esofageal neoplasia with one stage reconstruction. The follow up for these patients shows that this reconstruction method is a good, reliable choice with low costs and considerable advantages for the quality of life. Surgery for these patients should be considered primarily palliative and the optimal reconstruction should preserve the quality of life for the duration of survival.

Atrioesophageal fistula after cryoballoon pulmonary vein isolation.

The risk of atrioesophageal fistula after cryoballoon pulmonary vein isolation is thought to be much lower than after radiofrequency ablation, seeing that no data exist on this complication so far. We report for the first time on the occurrence of an atrioesophageal fistula 4 weeks after cryoballoon ablation at the site of the left inferior pulmonary vein. We suggest that even when using cryothermal ablation technique, an imaging modality to assess the proximity of esophagus and left atrium should be routinely performed to avoid this fatal complication.

Genital fistulas in female Crohn's disease patients.: clinical characteristics and response to therapy.

BACKGROUND: Genital fistulas (GF) can arise in the course of Crohn's disease (CD), are difficult to manage and determine a significant alteration of the quality of life. AIMS: To review the joint experience of the Inflammatory Bowel Disease Units in six University Hospitals in the management of GF in Crohn's disease on female patients. RESULTS: A total of 47 patients with GF were identified, affecting 3.8% of women with CD treated in our centers. A 47.5% of patients were smokers. The median of time from the diagnosis of CD reached 102 months. According to anatomical type, GF were classified as rectovaginal (74.5%), anovaginal/anovulvar (21.3%) and enterovaginal (4.3%). Main symptoms were vaginal discharge of fecal material (55.3%), vaginal passage of gas (40.4%), or both. Fistulas were treated with antibiotics in 59.6% of patients, without any lasting success. Thiopurines were used in 80.9% of cases, with 13.2% of complete and 23.7% of partial responses. Anti TNF-alpha therapy was applied in 63.8%, with a 16.7% of complete and a 30% of partial responses (all responding patients received infliximab). Surgery was indicated in 38.3% of patients, with a 22% of complete responses after a first operation and 38.8% after reintervention. In all, definitive closure after one or more of these therapies was achieved in only 31.9% of cases. CONCLUSION: Genital fistulas are a significant problem in female Crohn's disease patients. Therapy is not well defined and only partially effective (one in three cases). Surgical therapy stands out as the most effective treatment.

Post-operative wound infection in salvage laryngectomy: does antibiotic prophylaxis have an impact?

Salvage laryngectomy carries a high risk of post-operative infection with reported rates of 40-61%. The purpose of this study was to analyse infections in our own patients and review the potential impact of our current antibiotic prophylaxis (AP). A retrospective analysis of infection in 26 consecutive patients between 2000 and 2010 undergoing salvage total laryngectomy (SL) following recurrent laryngeal cancer after failed radiotherapy or chemo-radiation was undertaken. The antibiotic prophylaxis was intravenous teicoplanin, cefuroxime and metronidazole at induction and for the following 24 h. Infection was defined by Tabet and Johnson's grade 5, categorized as pharyngocutaneous fistula. Fifteen patients (58%) developed a post-operative wound infection, which occurred on average at 12 days after surgery. Univariate analysis demonstrated three risk variables that had a significant correlation with infection: alcohol consumption (p = 0.01), cN stage of tumour (p < 0.01), and pre-operative albumin levels <3.2 g/L (p = 0.012). There was a trend, though not significant, for increased infection in patients with high or low BMIs. The most common organisms isolated from clinical samples from infected patients were methicillin-resistant Staphylococcus aureus MRSA (43%), Pseudomonas aeruginosa (36%), Serratia marcescens, Proteus mirabilis and Enterococcus faecalis (7% each). All these organisms are typical hospital-acquired pathogens. Pseudomonas and Serratia were not covered by the prophylactic regime we used. The current antibiotic regime following SL is inadequate as the rate of infection is high. It would therefore seem logical to trial a separate antibiotic protocol of AP for patients undergoing SL that would include an extended course of antibiotics after the standard prophylaxis. In addition, infection rates may also be reduced by improving the metabolic state of patients pre-operatively by multi-disciplinary action. Steps should also be taken to reduce cross-infection with nosocomial pathogens in these patients. Other aspects of surgical management should be also taken in consideration.

A comparison of a cyanoacrylate [corrected] glue (Glubran) vs. fibrin sealant (Tisseel) in experimental models of partial pulmonary resection and lung incision [corrected] in rabbits.

INTRODUCTION: Bronchopleural fistulas (BPF) and air leaks (AL) present major complications after pulmonary resection. Various tissue sealants have been proposed for their prevention, e.g., fibrin sealant (FS) and cyanoacrylate glues (CA). Contrary to the safety record of FS, substantial side effects such as foreign body reaction and impaired tissue integration have been reported for CA. This study compares the sealing efficacy and biocompatibility as well as side effects of FS and CA in experimental partial pulmonary resection and lung incision in rabbits. METHODS: 26 New Zealand white rabbits (3 kg) were randomized to one of the three groups: partial pulmonary resection (A, acute model; n = 7 FS/ 7CA), lung incision [2 (B; n = 3 FS/ 3 CA)], and 14-day observation period (C; n = 3 FS/ 3 CA). In all groups (A, B, and C), FS was considered as control and CA as treatment. Surgery was carried out in general anaesthesia and mechanical ventilation. For partial lung resection a median thoracotomy was performed and the apex of the left median lobe was resected and the parenchymal surface covered with 0.09 ml of FS and CA. The thoracic cavity was filled with ringer solution after 5 minutes. The inspiratory minute volume (IMV) was increased by 0.02 l after every 4th inspiration. In groups B and C, a left lateral thoracotomy was performed in the 4th intercostal space and the left median lobe was incised with a scalpel. The incision was covered with 0.5 ml of FS or CA. At autopsy (B and C) the operation site was assessed macroscopically. Histology was performed in all animals. RESULTS: In terms of sealing purposes, FS and CA yielded comparable results in all groups. CA elicited a substantial increase of tissue temperature in the acute phase immediately after application (A). After 14 days CA residues were found, whereas FS was completely degraded. Histology showed a pronounced inflammatory response to CA but not to FS. We conclude that although the effect of airtight sealing was equally satisfying, our results emphasize that FS is preferable to CA for the prevention of BPF and AL due to superior biocompatibility and degradability. Longterm effects of CA residues on pulmonary tissue require further experimental testing.

[Neck chylous fistula: conservative treatment]. / Fístula linfática cervical: manejo conservador.

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

High dose of arginine enhanced enteral nutrition in postsurgical head and neck cancer patients. A randomized clinical trial.

OBJECTIVE: Patients with head and neck cancer undergoing surgery have a high incidence of postoperative complications. The aim of our study was to investigate whether postoperative nutrition of head and neck cancer patients, using a higher dose of arginine (20 g per day) could improve nutritional variables. MATERIALS AND METHODS: A population of 72 patients with oral and laryngeal cancer was enrolled. At surgery patients were randomly allocated to two groups: a) patients were receiving an enteral diet supplements with arginine and fiber (group I); b) patients were receiving an isocaloric, isonitrogenous enteral formula (group II). RESULTS: No significant intergroup differences in the trend of the three serum proteins and lymphocytes were detected. Gastrointestinal tolerance (diarrhea) of both formulas was good (7.89% group I and 5.88% group II: ns). The postoperative infections complications were similar in both groups (23.6% group I and 20.6% group II: ns). Fistula was less frequent in enriched nutrition group (5.2% group I and 17.6% group II: p = 0.026). The length of postoperative stay was better 24.3 +/- 14 days in the immunonutrition group than 36.1 +/- 27 days in the control group (p = 0.036). CONCLUSIONS: Enriched formula improves local wound complications in postoperative head and neck cancer patients and decreases length of stay.

Ear trauma caused by a yucca plant leaf spine.

Three uncommon cases of ear trauma caused by a yucca plant leaf spine are presented. One patient presented with tympanic perforation and the second with mixed hearing loss after spontaneous closure. The third patient probably had a perilymphatic fistula with subsequent labyrinthitis and hearing loss. Although the yucca is a ubiquitous plant, to the best of our knowledge, such incidents have not been previously reported.
