Localization of small islet-cell tumors. Preoperative and intraoperative ultrasound, computed tomography, arteriography, digital subtraction angiogra…
1985
A total of 42 islet-cell tumors were examined between 1972 and 1984. Problems of localization were only encountered in 31 tumors less than 2 cm in diameter. Of 31 small tumors, 27 were correctly localized using a combined diagnostic approach: ultrasound was successful in 12/20 tumors, CT in 9/21, angiography in 20/31, intraarterial digital subtraction angiography in 1/2, and pancreatic venous sampling in 13/16. The smallest tumor found by ultrasound and CT was 7 mm in diameter. Intraoperative ultrasound demonstrated all 9 insulinomas examined. Currently, the most useful techniques for localizing small islet-cell tumors are ultrasound, CT, and angiography. CT is particularly useful for tumor…

Stellenwert des Tumormarkers CA 19–9 in der Differentialdiagnose von Raumforderungen im Pankreaskopf
1996
In 96 patients (ductal pancreatic carcinoma, n = 34; periampullary carcinoma, n = 43; chronic pancreatitis, n = 19) the role of CA 19-9 in the diagnosis of lesions of the head of the pancreas were evaluated. The sensitivity for ductal pancreatic carcinoma was 73.3%, for periampullary carcinoma 48.8%, and specificity was 63.2%. Carcinoembryonic antigen was elevated only in every fifth patient. Even when combining the two tumor markers no increase in sensitivity could be observed. The low specificity of 63%, which decreased to 33% in the case of obstructive jaundice, does not allow adequate preoperative differentiation between cancer patients and those with chronic pancreatitis. In cases of p…
SIRT1 regulation of insulin-signalling pathways in liver, white adipose tissue and pancreas during fasting or calorie restriction
2007
In an excellent review by Yang et al.[1], published in issue 5 of Trends in Endocrinology and Metabolism, the involvement of the human sirtuin SIRT1 in nutrient-sensing and insulin-signalling pathways is explained. The regulation of SIRT1 with fasting in liver, pancreas and white adipose tissue is illustrated (see Figure 2 of Yang et al.). We consider that the depiction in the article by Yang et al. could be misleading for the reader, and we propose a modified version (Figure 1).
Hiatal herniation of the stomach and pancreas in a patient with oxygen desaturations
2013
Hiatal hernia (HH), a neglected cause of cardiorespiratory symptoms, is a frequent entity characterized by the displacement of the gastro- esophageal junction and part of the stomach into the mediastinum. Although often asymptomatic, HH may also exert a wide spectrum of clinical presentations due to cardio-pulmonary compression, including acute cardiovascular events such as arrhythmias, post-prandial syncope, angina-like chest pain, recurrent acute heart failure, hemodynamic collapse, electrocardiographic changes (T-wave inversion, ST elevation) simulating myocardial ischemia or pericarditis, and respiratory manifestations that can range from exercise intolerance and dyspnea on exertion to …
Outcome Quality Standards in Pancreatic Oncologic Surgery in Spain
2018
Introduction: To establish quality standards in oncologic surgery is a complex but necessary challenge to improve surgical outcomes. Unlike other tumors, there are no well-defined quality standards in pancreatic cancer. The aim of this study is to identify quality indicators in pancreatic oncologic surgery in Spain as well as their acceptable limits of variability. Methods: Quality indicators were selected based on clinical practice guidelines, consensus conferences, reviews and national publications on oncologic pancreatic surgery between the years 2000 and 2016. Variability margins for each indicator have been determined by statistical process control techniques and graphically represente…
Preoperative hepatic artery embolization before distal pancreatectomy plus celiac axis resection does not improve surgical results: A Spanish multice…
2021
Distal pancreatectomy with celiac axis resection (DP-CAR) is a surgical procedure with high morbidity and mortality performed in patients with locally advanced pancreatic cancer. Preoperative embolization of hepatic artery (PHAE) has been postulated as a technical option to increase resection rate.comparison of morbidity and mortality at 90 days, operative time, hospital stay and survival between patients that performed DP-CAR with and without PHAE.Observational retrospective multicentre study.patient operated in Spanish centers with DP-CAR for pancreatic cancer from April 2004 until 23 June 2018. Preoperative (PHAE, neodjuvant treatment), intraoperative (operative time and blood loss) and …
Pancreatoduodenectomy with artery-first approach.
2019
"Artery-first approach" encompasses different aspects for the surgical treatment of pancreatic cancer. It is a surgical technique or set of techniques which share in common the dissection of the main arterial vasculature involved in pancreatic cancer, before any irreversible surgical step is performed. On the other hand it represents the need for a meticulous dissection of the arterial planes and clearing of the retropancreatic tissue between the superior mesenteric artery, the common hepatic artery and portal vein in an attempt to achieve R0 resections. The recent expansion of this approach is based mainly on three factors: venous involvement should not be considered a contraindication for…
