Metabolic Evaluation of 94 Patients 5 to 16 Years After Ileocecal Pouch (Mainz Pouch 1) Continent Urinary Diversion
2003
PURPOSE In continent urinary diversion metabolic disturbances may be encountered in long-term followup. We evaluated metabolic consequences in patients with a minimum followup of 5 years after Mainz pouch 1 urinary diversion.At our institution continent urinary diversion using the ileocecal segment was performed between 1983 and 1995 in 458 patients. A total of 94 patients with an ileocecal pouch for a minimum of 5 years were reevaluated for metabolic changes. Median followup was 9.0 years. Routine laboratory parameters, blood gas analysis, vitamin B12, vitamin D25, cross-laps, bone specific alkaline phosphatase, osteocalcin and propeptide of type I collagen were obtained. Bone density was …
Surgical complications after endoscopic transsphenoidal pituitary surgery.
2009
Between January 2004 and June 2007 we conducted a retrospective analysis to assess post-operative complications related to endoscopic pituitary surgery in a series of 150 patients. Patients were treated with an endoscopic endonasal transsphenoidal approach to the sellar region for removal of pathological sellar and suprasellar lesions. We analysed the complications in groups according to the anatomical structures of the approach and the functional systems of the pituitary gland (anterior and posterior endocrine systems), and compared them to a large historical series using the traditional microsurgical transsphenoidal approach. Overall, we observed a decreased incidence of complications wit…
Conservative Surgery of Renal Carcinoma: The EIRSS Experience
1981
Summary— Seventy-two patients with renal carcinoma (RC) in a solitary kidney or bilateral synchronous tumours underwent parenchyma-sparing excision of their neoplasms. This was performed in situin 51 and extracorporeally in 21 kidneys, with a complication rate respectively of 1 7 and 43%. The 5-year survival rates were 78% for unilateral disease, 48% for bilateral synchronous and 38% for bilateral asynchronous disease. Survival correlated with Pcategory, grade and diameter of the tumour. Vascular invasion and spindle cells indicated a poor prognosis; the position of the tumour, oncocytic elements, calcification, lymphocytic infiltration or the predominance of clear cell or granular cells di…
The role of endoscopic retrograde cholangiopancreatography in the management of iatrogenic bile duct injury after cholecystectomy
2019
espanolIntroduccion: la lesion yatrogenica de la via biliar (LYVB) es una complicacion con elevada morbilidad tras la colecistectomia. En los ultimos anos la endoscopia ha adquirido un papel fundamental en el manejo de esta patologia. Metodos: estudio retrospectivo de LYVB tras colecistectomia abierta (CA) o colecistectomia laparoscopica (CL) tratadas en nuestro centro entre 1993 y 2017. Se analizaron los datos referentes a las caracteristicas clinicas, tipo de lesion segun la clasificacion de Strasberg-Bismuth, diagnostico, tecnica de reparacion y seguimiento. Resultados: se estudian 46 pacientes. La incidencia LYVB fue de 0,48%, 0,61% para las CL y 0,24% para las CA. El diagnostico se rea…
Cardiac surgery outcomes in patients with coronavirus disease 2019 (COVID-19): A case-series report
2020
Abstract Objective The impact of coronavirus disease 2019 (COVID-19) on the postoperative course of patients after cardiac surgery is unknown. We experienced a major severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak in our cardiac surgery unit, with several patients who tested positive early after surgery. Here we describe the characteristics, postoperative course, and laboratory findings of these patients, along with the fate of the health care workers. We also discuss how we reorganize and reallocate hospital resources to resume the surgical activity without further positive patients. Methods After diagnosis of the first symptomatic patient, surgery was suspended. Naso…
Lack of association of Aspergillus colonization with the development of bronchiolitis obliterans syndrome in lung transplant recipients: An internati…
2019
BACKGROUND: Bronchiolitis obliterans syndrome (BOS) is a major limitation in the long-term survival of lung transplant recipients (LTRs). However, the risk factors in the development of BOS remain undetermined. We conducted an international cohort study of LTRs to assess whether Aspergillus colonization with large or small conidia is a risk factor for the development of BOS.METHODS: Consecutive LTRs from January 2005 to December 2008 were evaluated. Rates of BOS and associated risk factors were recorded at 4 years. International Society of Heart and Lung Transplantation criteria were used to define fungal and other infections. A Cox proportional-hazards-model was constructed to assess the a…
Incidence of venous thromboembolism in patients undergoing thoracotomy for lung cancer
2008
Limited information exists on the incidence of symptomatic venous thromboembolism (vTE) in patients undergoing chest surgery for lung cancer. Several factors increase the thromboembolic risk in patients undergoing surgery for lung cancer: the intrinsic procoagulant effect of cancer,extensive surgical intervention, dependent limb position in the operating room, and vessel injury consequent to the operation. Furthermore,these patients might be especially vulnerable to pulmonary embolism (PE) because of the loss of lung tissue and the presence of chronic obstructive pulmonary disease and cardiovascular diseases caused by smoking.t Older studies found a very high incidence of thromboembolic eve…
Analysis of risk factors for neurological dysfunction in patients with acute aortic dissection type A: data from the German Registry for Acute Aortic…
2012
OBJECTIVES: Acute aortic dissection type A (AADA) is associated with major adverse events, such as transient or persistent neurological dysfunction (ND), which may be patient-, disease- or surgery-related. There is a lack of consensus regarding risk factors for ND in AADA patients. The aim of this study was to analyse and identify risk factors for new postoperative ND after aortic repair for AADA. METHODS: Between July 2006 and June 2010, 2137 AADA patients were enrolled in the multi-centre, prospective German Registry of AADA (GERAADA). Perioperative data were prospectively gathered from 50 institutes in Austria, Switzerland and Germany, and multivariate logistic regression analysis was pe…
Reproducibility of digital image analysis for measuring corneal haze after myopic photorefractive keratectomy.
1997
Purpose To evaluate the usefulness of digital image analysis for quantifying corneal haze by determining the reproducibility of its measurements at the corneal plane. Methods In a prospective study, 20 randomly selected eyes that had undergone myopic photorefractive keratectomy were photographed focusing the slit beam on their anterior corneal surface. Each photograph was examined using computer image analysis techniques that detect the edge of the reticular pattern of the image. Quantification of the difference between two areas, treated and adjacent untreated cornea, each containing 3,750 pixels with a resolution of 256 gray levels, was performed. Intra-analyzer variation was determined b…
Phakic intraocular lenses to correct high myopia
2003
Abstract Purpose: To evaluate the feasibility and safety of using phakic intraocular lenses (IOLs) to correct high myopia by comparing 3 IOL models: Adatomed, Staar, and Artisan. Setting: La Fe University Hospital, Department of Ophthalmology, and the Fundacion Oftalmologica del Mediterraneo, Valencia, Spain. Methods: In this prospective comparative study, a phakic IOL was implanted in 217 highly myopic eyes (118 patients). Fifty-nine eyes received an Adatomed IOL, 21 eyes a Staar IOL, and 137 eyes an Artisan IOL. The mean preoperative spherical equivalent was −15.39 diopters (D) ± 2.83 (SD), −16.00 ± 5.05 D, and −16.17 ± 2.75 D in the Adatomed, Staar, and Artisan groups, respectively. The …
