BACKGROUND Conventional upper endoscopy (EGD), EGD with side-view endoscope and ileoscopy are established procedures for endoscopic evaluation of patients with familial adenomatous polyposis (FAP). However, we still have little data on the frequency and relevance of adenomas in those parts of the small bowel which are not accessible to EGD and ileoscopy.(More)
INTRODUCTION Peutz-Jeghers syndrome (PJS) is characterised by a combination of hamartomatous gastrointestinal polyps and mucocutaneous melanin pigmentation. The polyps occur mainly in the small bowel and can lead to intestinal obstruction, intussusception and bleeding. Until only a few years ago, primary surgical resection and intraoperative endoscopy and(More)
BACKGROUND AND AIM Second-generation argon plasma coagulation (APC; APC 2/VIO APC) with its modes 'forced', 'pulsed', and 'precise' is a further development of the ICC/APC 300 system (first-generation APC). Until now, only limited data has existed on the use of APC 2. METHODS Fundamental data on the characteristics of the various APC 2 modes and clinical(More)
CASE REPORT A 69-year-old woman with splenic marginal-zone lymphoma was admitted with progressive abdominal pain and splenomegaly as the suspected cause of pain. Rituximab treatment (375 mg/m) had been initiated on the day of admission. Abdominal computerized tomography revealed splenic infarction. Laboratory tests showed elevation of liver enzymes and(More)
OBJECTIVE Shunting of the microcirculation contributes to the pathology of sepsis and septic shock. The authors address the hypothesis that shunting of the microcirculation occurs after superior mesenteric artery occlusion (SMAO) and reperfusion, and explore functional consequences. METHODS Spontaneously breathing animals (rats) (n = 30) underwent SMAO(More)
We evaluated late (4 hrs) effects of reperfusion on hemodynamics after 30 or 60 min occlusion of the superior mesenteric artery (SMA) in a rat model. Spontaneously breathing animals (n=30) underwent occlusion of the SMA for 0 (sham), 30 (SMAO_30) or 60 min (SMAO_60) followed by reperfusion with normal saline. Abdominal blood flow (ABF), SMA blood flow(More)
Activated complement contributes significantly to reperfusion injury after ischemia. This study explores functional consequences of C1-esterase inhibitor (C1-INH) treatment after superior mesenteric artery occlusion (SMAO)/reperfusion using intravital microscopy. Thirty anesthetized, spontaneously breathing, male Sprague-Dawley rats underwent SMAO for 60(More)
BACKGROUND The aim of this study was to evaluate the effect of 2nd generation argon plasma coagulation (VIO APC) with respect to the tissue destruction capacity, and to compare it with standard APC and Nd:YAG laser. METHODS 2nd generation APC (VIO APC2, Erbe, Germany), standard APC (APC 300/Erbotom ICC 200, Erbe) and Nd:YAG laser (KTP/YAG XP 800;(More)
