Tu1253 How Safe Is Sedation in Gastrointestinal Endoscopy? a Prospective Multicenter Trial: an Interim Analysis of 73,941 Endoscopies. Data From Pros…

were those plausibly associated with the procedure and severe enough for the patient to seek medical attention. We compared the proportion of patients with adverse events associated with gastrointestinal endoscopy identified with direct patient contact to the proportion identified through our current infrastructure using the chi-square statistic. Results: During the study period, 11,710 endoscopic procedures were performed on 9,683 patients. Our study personnel made 3205 calls over a three month period and ultimately made contact with 1999 (17%; 84.5% of those called) patients. 28 (1.4%) adverse events were identified through direct patient contact. Our adverse event tracking infrastructure…

Bowel ultrasonography in acute abdomen: beyond acute appendicitis.

2021

Acute abdomen is a common reason for consultation in the emergency department. A broad spectrum of entities, including diverse diseases of the gastrointestinal tract, can cause acute abdomen. Although computed tomography is the technique most widely used to evaluate acute abdomen in the emergency department, abdominal ultrasound is often performed first and allows bowel disease to be suspected. This article describes the ultrasound features of diverse bowel diseases that can cause acute abdomen, such as acute diverticulitis, bowel obstruction, gastrointestinal perforation, bowel ischemia, intraabdominal fat necrosis, and miscellaneous processes such as endometriosis, foreign bodies, or vasc…

An atypical clinical presentation of acute appendicitis in a young man with midgut malrotation

2007

Abstract Midgut malrotation occurs as a result of failure in normal intestinal rotation and fixation during early pregnancy. Pathological conditions reported in the literature involving midgut malrotation predominantly relate to infants and children. In adults malrotation is often revealed as an incidental finding on computed tomography (CT), or the associated altered anatomy can be the cause of atypical clinical symptoms of relatively common intestinal disorders. An unusual presentation of acute appendicitis, with fever and recurrent pain in left iliac fossa is reported. Underlying intestinal malrotation delayed the correct clinical diagnosis of acute appendicitis. It was not until a CT sc…

Surveillance colonoscopy in ulcerative colitis: magnifying chromoendoscopy in the spotlight

2004

Chromoendoscopy in ulcerative colitis may offer the possibility of detecting dysplastic or neoplastic changes at a curable stage, and thus expand the indication for chromoendoscopy from screening to surveillance colonoscopy Colonoscopy is the gold standard for colorectal cancer screening.1–3 Detection and complete removal of adenomas disrupt the adenoma-carcinoma sequence and thus prevent the development of colorectal cancer. However, endoscopists still fear that they may have overlooked relevant lesions despite the availability of modern videoendoscopes. This problem is underlined by a relatively high rate of adenomas missed by conventional endoscopy (up to 27%), as determined by back to b…

Conventional Radiology in the Evaluation of the Small Bowel

2015

For many years, the small bowel has been considered as the “black box” of the gastrointestinal system because it could not be evaluated through endoscopy. For this reason, the conventional radiological methods, such as small bowel enteroclysis and small bowel follow-through, have been considered the standard approach for the evaluation of the small bowel in the diagnosis and management of Crohn’s disease for years. However, due to technological limits, the study of small bowel through conventional radiology has been focused mainly on its function than on its anatomy. To date, the conventional examination with the study of intestinal transit is now rarely used, if not obsolete, but it has st…

Advanced Endoscopic Imaging Methods

2021

Endoscopic imaging is the mainstay of gastrointestinal endoscopy and has experienced remarkable improvements in recent decades. Further endoscopic innovations stemming from major technological advances such as artificial intelligence and deep learning are at advanced stages of development and will be increasingly deployed in routine clinical practice. These will improve the detection and enable real-time optical diagnosis of pathologies in the gastrointestinal tract. Furthermore, the utilization of endoscopic robots may result in higher diagnostic yield and greater patient comfort. This chapter covers the most recent developments around computer-assisted diagnosis, hypoxia and three-dimensi…

Colonoscopy, Tumors, and Inflammatory Bowel Disease - New Diagnostic Methods

2006

Accurate detection of premalignant lesions and early cancers in the colon is essential for curative endoscopic or surgical therapy, since the prognosis for the affected patients is closely related to the size and stage of the neoplastic lesion. Total colonoscopy is the accepted gold standard for screening and surveillance of colorectal cancer. This review summarizes recently published diagnostic developments and key findings in the areas of colonoscopy, colonic tumors, and inflammatory bowel diseases. Relevant findings have been reported for chromo-endoscopy in the diagnosis of colitis-associated neoplasia, as well as flat and depressed adenomas. Real-time Doppler capabilities have now been…

Obere gastrointestinale Blutung mit hämorrhagischem Schock am Ende einer Urlaubsreise: Präklinische und innerklinische Versorgung eines gastrointesti…

2014

ZusammenfassungNach der Rückkehr aus dem Urlaub wurde ein 55-jähriger Patient mit Teerstuhl und hämorrhagischem Schock im Zugabteil eines InterCity der Deutschen Bahn notfallmedizinisch versorgt und in ein Krankenhaus der Maximalversorgung eingeliefert. Hier erfolgte zunächst die weitere notfallmedizinische Behandlung, in deren Rahmen in der internistischen Notaufnahme in interdisziplinärer Zusammenarbeit eine Stabilisierung der Hämodynamik sowie die Sicherung der Atemwege und Atemfunktion erfolgten. Anschließend wurde eine Notfall-Endoskopie des oberen Gastrointestinaltrakts durchgeführt. Ursächlich für das hämorrhagische Schockgeschehen war eine arteriell spritzende, endoskopisch nicht zu…

Clinical pharmacokinetics of atenolol — A review

1982

Atenolol is a hydrophilic betareceptor blocking drug, which is predominantly eliminated via the kidneys, only about 5% of the atenolol is metabolised by the liver. After oral administration atenolol is incompletely absorbed from the intestine, so about 50% of the beta blocker are finally biovailable. In plasma only 3% of atenolol are protein-bound. There exists a linear relationship between the atenolol plasma levels and the degree of beta blocking effect measured by inhibition of the exercise-induced tachycardia. No correlation was found between plasma levels of atenolol and blood pressure lowering activity of the drug. After oral administration elimination half life of atenolol is calcula…
