Myéloradiculopathie chronique progressive chez un homme de 61 ans [Chronic progressive myeloradiculopathy in a 61-year-old man]

A painful worsening of known difficulties in walking led us to investigate a man who presented a spastic paraparesis. Radiological investigations had to be repeated three times before making a diagnosis of a right C6 spinal dural arteriovenous fistula after a 22-month follow-up. Knowing the mechanisms leading to spinal venous hypertension may explain the low yield of the early radiological investigations that should be repeated. The efficiency of the treatment depends on the severity of the presurgical neurologic manifestations.

Predictors for hospitalization and outpatient visits in patients with inflammatory bowel disease: results from the Swiss Inflammatory Bowel Disease Cohort Study.

OBJECTIVES: Patients with inflammatory bowel disease (IBD) have a high resource consumption, with considerable costs for the healthcare system. In a system with sparse resources, treatment is influenced not only by clinical judgement but also by resource consumption. We aimed to determine the resource consumption of IBD patients and to identify its significant predictors. MATERIALS AND METHODS: Data from the prospective Swiss Inflammatory Bowel Disease Cohort Study were analysed for the resource consumption endpoints hospitalization and outpatient consultations at enrolment [1187 patients; 41.1% ulcerative colitis (UC), 58.9% Crohn's disease (CD)] and at 1-year follow-up (794 patients). Predictors of interest were chosen through an expert panel and a review of the relevant literature. Logistic regressions were used for binary endpoints, and negative binomial regressions and zero-inflated Poisson regressions were used for count data. RESULTS: For CD, fistula, use of biologics and disease activity were significant predictors for hospitalization days (all P-values <0.001); age, sex, steroid therapy and biologics were significant predictors for the number of outpatient visits (P=0.0368, 0.023, 0.0002, 0.0003, respectively). For UC, biologics, C-reactive protein, smoke quitters, age and sex were significantly predictive for hospitalization days (P=0.0167, 0.0003, 0.0003, 0.0076 and 0.0175 respectively); disease activity and immunosuppressive therapy predicted the number of outpatient visits (P=0.0009 and 0.0017, respectively). The results of multivariate regressions are shown in detail. CONCLUSION: Several highly significant clinical predictors for resource consumption in IBD were identified that might be considered in medical decision-making. In terms of resource consumption and its predictors, CD and UC show a different behaviour.

La lymphadénite à mycobactérie atypique [Lymphadenitis due to atypical mycobacteria]

La lymphadénite est une maladie courante dans l'enfance et un motif fréquent de consultation pédiatrique ou ORL. Elle est habituellement due à une infection des voies respiratoires hautes et est autolimitée. Chez l'enfant présentant une lymphadénite cervicale subaiguë ou chronique qui ne répond pas aux antibiotiques habituels, une infection à mycobactérie atypique doit être évoquée. L'infection touche surtout les enfants en bonne santé entre un et cinq ans. Le diagnostic précoce est essentiel car le traitement de choix est l'exérèse des ganglions atteints, avant l'apparition d'une nécrose cutanée et d'une fistulisation. Cet article revoit les présentations cliniques spécifiques, les méthodes diagnostiques et le traitement des lymphadénites à mycobactéries atypiques. Cervical lymphadenitis is common in childhood and is a frequent source of consultation at the pediatrician's or ENT's office. It is usually caused by a viral upper respiratory tract infection and is self limited. In children with subacute or chronic cervical lymphadenitis which fails to respond to conventional antibiotics, infection due to atypical mycobacteria should always be considered. Infections occur predominantly in an otherwise healthy child of 1 to 5 years of age. The early diagnosis is essential as the treatment of choice is early surgical excision before skin necrosis and fistula occur. This article reviews the specific clinical manifestations, diagnostic tools and treatment of lymphadenitis due to atypical mycobacteria.

Removal of unusual, large high-velocity metallic maxillary sinus foreign bodies by a modified free bone flap technique.

Metallic foreign bodies are rarely found in the maxillary sinus, and usually they have a dental origin.Potential complications related to foreign bodies include recurrent sinusitis, rhinolith formation, cutaneous fistula,chemical poisoning, facial neuralgic pain and even malignancies.Two main surgical approaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus techniques. We are reporting two unusual cases of large high-velocity foreign bodies removed by a modified maxillary lateral antrotomy,with free bone flap repositioning and fixation with a titanium miniplate.

Fistulizing Crohn's disease.

Fistulas are common in Crohn's disease. A population-based study has shown a cumulative risk of 33% after 10 years and 50% after 20 years. Perianal fistulas were the most common (54%). Medical therapy is the main option for perianal fistula once abscesses, if present, have been drained, and should include antibiotics (both ciprofloxacin and metronidazole) and immunomodulators. Infliximab should be reserved for refractory patients. Surgery is often necessary for internal fistulas.

Vacuum-assisted closure device for the management of infected postpneumonectomy chest cavities.

BACKGROUND: Infected postpneumonectomy chest cavities may be related to chronic postpneumonectomy empyema or arise in rare situations of necrotizing pneumonia with complete lung destruction where pneumonectomy and pleural debridement are required. We evaluated the safety and efficacy of an intrathoracic vacuum-assisted closure device (VAC) for the treatment of infected postpneumonectomy chest cavities. METHOD: A retrospective single institution review of all patients with infected postpneumonectomy chest cavities treated by VAC between 2005 and 2013. Patients underwent surgical debridement of the thoracic cavity, muscle flap closure of the bronchial stump when a fistula was present, and repeated intrathoracic VAC dressings until granulation tissue covered the entire chest cavity. After this, the cavity was obliterated by a Clagett procedure and closed. RESULTS: Twenty-one patients (14 men and 7 women) underwent VAC treatment of their infected postpneumonectomy chest cavity. Twelve patients presented with a chronic postpneumonectomy empyema (10 of them with a bronchopleural fistula) and 9 patients with an empyema occurring in the context of necrotizing pneumonia treated by pneumonectomy. In-hospital mortality was 23%. The median duration of VAC therapy was 23 days (range, 4-61 days) and the median number of VAC changes per patient was 6 (range, 2-14 days). Infection control and successful chest cavity closure was achieved in all surviving patients. One adverse VAC treatment-related event was identified (5%). CONCLUSIONS: The intrathoracic VAC application is a safe and efficient treatment of infected postpneumonectomy chest cavities and allows the preservation of chest wall integrity.

Place actuelle de la papillotomie chirurgicale transduodénale [Current status of surgical transduodenal papillotomy].

The treatment of biliary lithiasis has changed during the past 20 years. Cholecystectomy remains the gold standard for cholelithiasis, but many options are available for calculi of the common bile duct. Among them are surgical open or laparoscopic choledochotomy, biliary-enteric anastomosis, transduodenal sphincterotomy (TDS), endoscopic sphincterotomy. With the aim to describe the current place of TDS, we reviewed the patients operated on in our department between 1976 and 1992. We found 78 patients with a mean age of 58 years (26-89 years). 34 (43%) of them had acute cholecystitis, with 26 being operated on urgently. 47 (60%) were jaundiced, 15 (19%) had pancreatitis and 12 (15%) had cholangitis before operation. Indications for TDS have been impacted stone or absence of progression of the contrast medium on intraoperative cholangiography in 71 patients (91%). 3 patients died (1 pulmonary embolism, 1 sepsis of pulmonary origin, 1 MOF syndrome complicating preoperative necrotizing pancreatitis). 30 patients (38%) had complications, of which 20 were directly related to TDS. Hemorrhage occurred in 4 cases, and resolved spontaneously without transfusion. Hyperamylasemia occurred in 17 instances, but clinical pancreatitis developed in only 1 case, with complete resolution. 1 duodenal fistula healed after conservative therapy. No death is attributable directly to TDS. Today, the importance of endoscopic sphincterotomy is increasing. This retrospective study shows that TDS, if performed with caution, does not increase the operative risks even in emergent operations. During surgical exploration of the common bile duct, TDS is indicated to remove an impacted stone, or as a bilio-enteric anastomosis if multiple stones are present with a thin common duct.(ABSTRACT TRUNCATED AT 250 WORDS)

Aorto-bronchial and aorto-pulmonary fistulation after thoracic endovascular aortic repair: an analysis from the European Registry of Endovascular Aortic Repair Complications.

OBJECTIVES: To learn upon incidence, underlying mechanisms and effectiveness of treatment strategies in patients with central airway and pulmonary parenchymal aorto-bronchial fistulation after thoracic endovascular aortic repair (TEVAR). METHODS: Analysis of an international multicentre registry (European Registry of Endovascular Aortic Repair Complications) between 2001 and 2012 with a total caseload of 4680 TEVAR procedures (14 centres). RESULTS: Twenty-six patients with a median age of 70 years (interquartile range: 60-77) (35% female) were identified. The incidence of either central airway (aorto-bronchial) or pulmonary parenchymal (aorto-pulmonary) fistulation (ABPF) in the entire cohort after TEVAR in the study period was 0.56% (central airway 58%, peripheral parenchymal 42%). Atherosclerotic aneurysm formation was the leading indication for TEVAR in 15 patients (58%). The incidence of primary endoleaks after initial TEVAR was n = 10 (38%), of these 80% were either type I or type III endoleaks. Fourteen patients (54%) developed central left bronchial tree lesions, 11 patients (42%) pulmonary parenchymal lesions and 1 patient (4%) developed a tracheal lesion. The recognized mechanism of ABPF was external compression of the bronchial tree in 13 patients (50%), the majority being due to endoleak formation, further ischaemia due to extensive coverage of bronchial feeding arteries in 3 patients (12%). Inflammation and graft erosion accounted for 4 patients (30%) each. Cumulative survival during the entire study period was 39%. Among deaths, 71% were attributed to ABPF. There was no difference in survival in patients having either central airway or pulmonary parenchymal ABPF (33 vs 45%, log-rank P = 0.55). Survival with a radical surgical approach was significantly better when compared with any other treatment strategy in terms of overall survival (63 vs 32% and 63 vs 21% at 1 and 2 years, respectively), as well as in terms of fistula-related survival (63 vs 43% and 63 vs 43% at 1 and 2 years, respectively). CONCLUSIONS: ABPF is a rare but highly lethal complication after TEVAR. The leading mechanism behind ABPF seems to be a continuing external compression of either the bronchial tree or left upper lobe parenchyma. In this setting, persisting or newly developing endoleak formation seems to play a crucial role. Prognosis does not differ in patients with central airway or pulmonary parenchymal fistulation. Radical bronchial or pulmonary parenchymal repair in combination with stent graft removal and aortic reconstruction seems to be the most durable treatment strategy.

Endovascular treatment of pulmonary arteriovenous malformations in hereditary haemorrhagic telangiectasia.

PRINCIPLES: To assess the efficiency and complication rates of vaso-occlusion of pulmonary arteriovenous malformations (PAVMs) in Rendu-Osler-Weber disease (hereditary haemorrhagic telangectasia; HHT). METHODS: Seventy-two patients were investigated in our institution for HHT between March 2000 and November 2011. Sixteen presented PAVMs (22.2%), and 11 (68.8%) were treated with vaso-occlusion for a total of 18 procedures. Procedures included coils, plugs and combined approaches. Immediate success and recurrence rate, complication were recorded, as well as persistent and new PAVMs during clinical and computed tomography (CT) follow-up. RESULTS: Eighteen procedures were performed and a total of 37 PAVMs were treated, 19 with coils, 16 with plugs and 2 with combined treatment. Mean CT follow-up time was 41 months (1‒164). No major complication was observed. One distal translocation was treated during the same intervention. Two PAVMs persisted after treatment (5.7%), both treated by means of plug embolisation. One new PAVM was observed during follow-up CT. PAVMs with an afferent artery of less than 3mm or asymptomatic PAVMs were not treated. CONCLUSION: Recent studies have demonstrated that vaso-occlusion has become the gold standard treatment for PAVM. This study is in accordance with previous results and shows a minimal complication rate and little recurrence, whether by coils, plugs, or combined treatments.

Effect of Antecolic versus Retrocolic Gastroenteric Reconstruction after Pancreaticoduodenectomy on Delayed Gastric Emptying: A Meta-Analysis of Six Randomized Controlled Trials.

BACKGROUND: One of the most frequent complications of pancreaticoduodenectomy (PD) is delayed gastric emptying (DGE). The study aim was to evaluate the impact of the type of gastro/duodenojejunal reconstruction (antecolic vs. retrocolic) after PD on DGE incidence. METHODS: A systematic review was made according to the PRISMA guidelines. Randomized controlled trials (RCTs) comparing antecolic vs. retrocolic reconstruction were included irrespective of the PD techniques. A meta-analysis was then performed. RESULTS: Six RCTs were included for a total of 588 patients. The overall quality was good. General risk of bias was low. DGE was not statistically significantly different between the antecolic and retrocolic group (OR 0.6, 95% CI 0.31-1.16, p = 0.13). The other main surgery-related complications (pancreatic fistula, hemorrhage, intra-abdominal abscess, bile leak and wound infection) were not dependent on the reconstruction route (OR 0.84, 95% CI 0.41-1.70, p = 0.63). No statistically significant difference in terms of length of hospital stay was found between the 2 groups. There was also no difference of DGE incidence if only pylorus-preserving PD was considered and between the DGE grades A, B or C. CONCLUSION: This meta-analysis shows that antecolic reconstruction after PD is not superior to retrocolic reconstruction in terms of DGE.

Rendu-Osler-Weber syndrome: what radiologists should know. Literature review and three cases report

Rendu-Osler-Weber syndrome or hereditary hemorrhagic telangiectasia is an autosomal dominant vascular disease involving multiple systems whose main pathological change is the presence of abnormal arteriovenous communications. Most common symptoms include skin and mucosal telangiectasias, epistaxis, gastrointestinal, pulmonary and intracerebral bleeding. The key imaging finding is the presence of visceral arteriovenous malformations. The diagnosis is based on clinical criteria and can be confirmed by molecular biology techniques. Treatment includes measures for management of epistaxis, as well as surgical excision, radiotherapy and embolization of arteriovenous malformations, with emphasis on endovascular treatment. The present pictorial essay includes a report of three typical cases of this entity and a literature review.

Use of Bichat"s buccal fat pad for the sealing of orosinusal communications. A presentation of 8 cases

Objectives: To determine the efficacy of the pediculate flap with the buccal fat pad in the sealing of orosinusal communications, describe the surgical technique used, and report the main complications. Patients and method: A retrospective study was made of 8 patients seen in the Service of Oral Surgery of the University of Barcelona Dental Clinic (Spain) for the treatment of orosinusal communications between the years 2007 and 2009. In all cases a pediculate flap with the buccal fat pad was used to solve the problem. Results: All of the orosinusal communications were successfully resolved with this technique. The immediate postoperative complications were pain (37.5%), inflammation (37.5%), edema (32.5%), trismus (37.5%), halitosis (14.3%), suppuration (12.5%) and rhinorrhea (12.5%). Conclusions: The use of Bichat"s buccal fat pad is not regarded as the technique of choice for sealing small to medium sized orosinusal communications. However, in the case of large communications, it is a good option, and the results obtained are optimum.

Conduta terapêutica atual no adenocarcinoma da cárdia e da junção esofagogástrica

Adenocarcinomas of the cardia and gastroesophageal junction are peculiar entities with three different origins, which differ somewhat from other adenocarcinomas of the stomach in their clinical presentation and pathogenesis, and have a poorer prognosis. In this article the authors reviewed definitions, incidence and epidemiology, etiologic factors, genetic implications, clinical presentation, diagnosis, staging and treatment, with emphasis on the surgical approach, discussing the current management of these cancers. The prognostic factors related specifically to the cardia cancers are: esophageal invasion greater than 3cm, microscopic residual tumor and wall penetration (>T2). Preoperative workup should include computed tomography, and endoscopic ultrasonography and laparoscopy when available. Preoperative recognition of T3/ T4/N2 lesions should indicate inclusion in neo-adjuvant protocols whenever possible. The authors present the results of 46 resected cases of adenocarcinomas of the cardia and GE junction of the Instituto Nacional do Câncer- Brazil (1981-1995). Cure was intended in 29 and palliation in 17 patients. The most common type of resection was total gastrectomy with abdominal esophagectomy (28 cases). Morbidity (major and minor) occurred in 50% of the patients. The main causes were of respiratory origin and fistulas (19.6% each). Death occurred in 44% of the patients with fistula. Postoperative death until the 30th day occurred in 17.24% of the curative cases and in 23.52% of the palliative ones. The median survival time was 68.5 months for stage I, 25 months for stage II, 31 months for stage III and 12.5 months for stage IV diseases. The median survival time was 8 months for palliation and 28.5 months for cure. No long-term survival was obtained with the palliative group, whereas 25% survived five years of more in the curative group. The authors conclude that the surgical approach should be the one the surgeon feels more comfortable with. Complete removal of the disease proved by frozen section, splenectomy and D2 lymphadenectomy should be the standard therapy with curative intent.

Apendicite em hérnia femoral com formação de fístula estercoral

The presentation of acute appendicitis in femoral hernia is rare. The gastrointestinal symptons are overshadowed by the local findings. This may lead to delayed diagnosis and complications such as formation of fistula. The authors report a case of a 76-year-old female patient which presented with stercoral fistula after drainage of a right groin abscess ten months earlier.

Coleperitônio após colecistectomia convencional tratado por via laparoscopica

Videolaparoscopy is the estabilished treatment for chronic or acute cholecystitis, with low complications rates. Among operative complications, biliar peritonitis, biliar fistula and common bile duct injuries despite rare, can be difficult to treat. The autors present the results of videolaparoscopic treatment of choleperitoneum in four patients submitted previously to a conventional cholecystectomy. Among operative complications, biliar peritonites, biliary fistula and common bile duct injuries. No complications related to laparoscopic procedure were observed.
