Pancreatic and periampullary tumours: morbidity, mortality, functional results, and long-term survival
2009
Abstract Aims To evaluate postoperative morbidity and mortality, pancreatic function and long-term survival in patients with surgically treated pancreatic or periampullar tumours. Patients and methods Cohort study including 160 patients consecutively operated on: 80 pancreaticoduodenectomies (PD), 30 distal pancreatectomies (DP), 7 total pancreatectomies, 4 central pancreatic resections, and 3 ampullectomies. The tumour was not resected in 36 patients. Pancreatic function was evaluated by oral glucose tolerance test, faecal fat excretion, and elastase. Results Resectability rate was 77.5%. In resected patients (n = 124), 38.7% had complications with a pancreatic fistula rate of 6.4% and a m…
Heterogeneous Oxygenation of Rectal Carcinomas in Humans: A Critical Parameter for Preoperative Irradiation?
1984
The surgical treatment of rectal carcinoma in humans is often combined with irradiation. However, the efficacy of this latter treatment modality is crucially influenced by the oxygenation status of the tumor tissue to be treated. Therefore, the knowledge of the O2 supply to the tumor tissue is a decisive prerequisite for the assessment of the efficiency of radiotherapy.
0432: Impact of admission hyperglycemia on one-year mortality in non-diabetic patients admitted for rescue PCI: Data from the “Observatoire des infar…
2014
BackgroundRescue percutaneous coronary intervention (PCI) is associated with improved clinical outcomes for ST-segment myocardial infarction (STEMI) patients after failed fibrinolysis therapy. Hyperglycemia on admission has been shown to be a powerful predictor of mortality after acute myocardial infarction, particularly in non-diabetic patients. The aim of our study was to assess the predictive value of admission glucose levels on long-term mortality in patients with rescue PCI.Patients and MethodsFrom the “Observatoire des infarctus de Côte d’Or” (RICO) survey, 510 consecutive non-diabetic STEMI patients admitted to the intensive care unit for rescue PCI after failed fibrinolysis therapy …
Endophthalmitis in cataract surgery
1999
Abstract Objective To document perioperative prophylactic treatment and to evaluate the risk factors for endophthalmitis after cataract surgery. Design Cross-sectional study via anonymous survey. Participants Four hundred sixty-nine centers in Germany were queried. Results A total of 311 (67%) questionnaires were received, with each center reporting an average of 900 cataract surgeries per year (total, 340,633 surgeries in 1996). Respondents reported a total of 267 cases of endophthalmitis, which resulted in a mean responder-specific endophthalmitis rate of 0.148% versus a median rate of 0%. Statistical analysis via Poisson regression suggested that sclerocorneal incisions were associated w…
The use of nephrometry scoring systems can help urologists predict the risk of conversion to radical nephrectomy in patients scheduled for partial ne…
2019
Conversion to radical nephrectomy (RN) in patients scheduled for partial nephrectomy (PN) is an important outcome that should be strongly considered during the decision-making process and adequately discussed with patients during their preoperative counseling. This unplanned event could be due to severe intraoperative complications or oncologic reasons. Intraoperative suspicion of hilar and/or perirenal fat tissue involvement, peritumoral venous involvement, tumor multifocality and/or iatrogenic rupture of the tumor are the most common conditions threatening the oncological safety of the procedure.
Supplemental Perioperative Oxygen and the Risk of Surgical Wound Infection<SUBTITLE>A Randomized Controlled Trial</SUBTITLE>
2005
ContextSupplemental perioperative oxygen has been variously reported to halve or double the risk of surgical wound infection.ObjectiveTo test the hypothesis that supplemental oxygen reduces infection risk in patients following colorectal surgery.Design, Setting, and PatientsA double-blind, randomized controlled trial of 300 patients aged 18 to 80 years who underwent elective colorectal surgery in 14 Spanish hospitals from March 1, 2003, to October 31, 2004. Wound infections were diagnosed by blinded investigators using Centers for Disease Control and Prevention criteria. Baseline patient characteristics, anesthetic treatment, and potential confounding factors were recorded.InterventionsPati…
Die Sonoanatomie des Spinalkanales der LWS
2008
UNLABELLED Results of an Experimental Study and Report of Intraoperative Application: AIM Intraoperative sonography has been used in neurosurgery (especially in tumors) and in traumatology (assess reduction of dorsal vertebral body fragments). This study was performed to determine the value of sonography in detecting vertebral disc tissue. RESULTS We examined 6 specimens of the Lumbar spine using the extended flavectomy approach. We found that sono-anatomy was reproducible and that the assessable area was large enough to make sonography useful for detection of sequesters. Dislocated vertebral disc tissue could be differentiated clearly from original disc tissue and from other intraspinal st…
Cerebral Autoregulation in Non-Brain Injured Patients: A Systematic Review.
2021
Introduction: Cerebral autoregulation (CA) plays a fundamental role in the maintenance of adequate cerebral blood flow (CBF). CA monitoring, through direct and indirect techniques, may guide an appropriate therapeutic approach aimed at improving CBF and reducing neurological complications; so far, the role of CA has been investigated mainly in brain-injured patients. The aim of this study is to investigate the role of CA in non-brain injured patients.Methods: A systematic consultation of literature was carried out. Search terms included: “CA and sepsis,” “CA and surgery,” and “CA and non-brain injury.”Results: Our research individualized 294 studies and after screening, 22 studies were anal…
Enteral Nutrition in Pancreaticoduodenectomy: A Literature Review
2015
Pancreaticoduodenectomy (PD) is considered the gold standard treatment for periampullory carcinomas. This procedure presents 30%–40% of morbidity. Patients who have undergone pancreaticoduodenectomy often present perioperative malnutrition that is worse in the early postoperative days, affects the process of healing, the intestinal barrier function and the number of postoperative complications. Few studies focus on the relation between enteral nutrition (EN) and postoperative complications. Our aim was to perform a review, including only randomized controlled trial meta-analyses or well-designed studies, of evidence regarding the correlation between EN and main complications and outcomes af…
Perioperative chemotherapy with fluorouracil plus leucovorin, oxaliplatin, and docetaxel versus fluorouracil or capecitabine plus cisplatin and epiru…
2019
Background Docetaxel-based chemotherapy is effective in metastatic gastric and gastro-oesophageal junction adenocarcinoma. This study reports on the safety and efficacy of the docetaxel-based triplet FLOT (fluorouracil plus leucovorin, oxaliplatin and docetaxel) as a perioperative therapy for patients with locally advanced, resectable tumours. Methods In this controlled, open-label, phase 2/3 trial, we randomly assigned 716 patients with histologically-confirmed advanced clinical stage cT2 or higher or nodal positive stage (cN+), or both, resectable tumours, with no evidence of distant metastases, via central interactive web-based-response system, to receive either three pre-operative and t…
