143. Operationsindikation bei akuter Pankreatitis

Zusammenfassung Die Indikation zur Operation bei der AHNP ist bestimmt durch den Schweregrad und die Verlaufsdynamik der Erkrankung: Beides muß täglich neu kontrolliert und abgeschätzt werden, wobei hilfreiche Parameter vor allem das klinische Bild und einfache Labordaten sind. Die Computertomographie trägt nur bedingt zur Indikation bei. Eine Frühoperation ist indiziert bei Versagen der Intensivtherapie, Sepsis und vor allem bei drohender Nieren- und Lungeninsuffizienz. Eine Operation im postakuten Stadium sollte ebenfalls bei septischen Komplikationen durchgeführt werden. Engmaschige Verlaufskontrollen sind hier erforderlich.

Indication for surgery in acute pancreatitis

Summary The indication for surgery in acute hemorrhagic necrotizing pancreatitis (AHNP) depends on the severity of the disease and the clinical course. Both factors must be determined daily, based on clinical and laboratory data. CAT-scan does not contribute much to indication. An early operation is necessary if despite an optimal intensive care septic symptoms and signs persist and renal and respiratory failure occur. Surgery is indicated 2–3 weeks after onset of AHNP if septic complications (re)-occur. A close follow up is mandatory.

An uncommon cause of acute right ventricular failure and high mixed venous oxygen saturation

Ruptured sinus of Valsalva aneurysms are rare. We report a case in which the usual clinical manifestations were not present and the patient was initially treated as an acute pulmonary embolus. Despite three negative echocardiograms an intra-cardiac shunt was suspected because of a persistently elevated mixed venous oxygen saturation. Cardiac catheterisation confirmed the diagnosis. Surgical repair was performed and post operative recovery was uneventful.     

Interdigestive small bowel motility and duodenal bacterial overgrowth in experimental acute pancreatitis

The objective of this study is to investigate the effects of an acute necrotizing pancreatitis (ANP), without biliary obstruction, on the migrating motor complex (MMC), small bowel bacterial overgrowth (SBBO), bacterial translocation (BT) and infection of the pancreas simultaneously. Rats were divided into four groups: mild pancreatitis, control, ANP and sham operated control. Jejunal myoelectrodes were used to measure MMCs. Blood, peritoneal fluid, bile, and abdominal organs were harvested for microbial culturing 72 h after induction of pancreatitis. The splenic portion of the pancreas was taken for histology. During ANP the MMC cycle length was significantly increased from 14.1 +/- 0.2 to 22.4 +/- 1.9 min (P < 0.05). The duodenum of ANP rats was in contrast with the other groups characterized by Enterobacteriacae (> 3 log 10 CFU g-1 in seven of 12 rats, P < 0.05). A positive correlation (r = 0.78, P < 0.01) existed between duodenal Gram-negative and anaerobic flora and the MMC cycle. Correlation between MMC cycle length and BT to the pancreas was positive as well (r = 0.70, P < 0.01). A positive correlation (r = 0.85, P < 0.01) was found between the severity of pancreatitis and duodenal bacterial overgrowth. During ANP without biliary obstruction, the jejunal MMC is disturbed and consequently SBBO occurs. The correlation between the severity of pancreatitis, the disturbance of the MMC and SBBO suggests an important pathophysiological role of the proximal small bowel in the infection of pancreatic necrosis.     

Practical selection criteria for unenhanced cranial CT in patients with acute headache

We studied clinical predictors of cranial computed tomography (CT) abnormalities in patients with acute or acutely worsened headache. Data were collected from chart review of 333 consecutive patients presenting to an emergency department and who were clinically selected for cranial CT. Patients with a positive neurologic examination were at 10.7 times greater risk for a positive CT than the rest of the sample (p<1.5 – 10⁻¹⁰). Using only neurologic examination to select patients for CT would have missed 30.3% of the positive scans. The amnesia, depressed sensorium, and hypertension variables had CT yields approximating 10% or greater even in the presence of a negative neurologic examination. Together with a positive neurologic examination, these variables detected 87.9% of the patients in this sample with positive scans; their absence had a negative predictive value of 98.0%. Of the four patients with positive scans who would have been missed using this strategy, one was discharged directly from the emergency department anyway and the other three developed positive neurologic examinations within 24 hours. One died of causes unrelated to the intracranial pathology. Positive neurologic examination, hypertension, history of amnesia, or a depressed sensorium provide reasonable initial guidelines to select for CT patients with an acute headache.     

Late Effects of Childhood Acute Leukemia and Its Treatment

Late effects of childhood acute leukemia and its treatment were studied in 766 patients (684 ALL, 73 ANLL, and 9 others) in Japan who had remained in remission for more than 1 year after their first complete remission. Delayed adverse sequelae involve a wide variety of organs and their functions. Short stature was present in 2.61%, obesity in 3.79%, abnormalities of growth hormone secretion in 1.5%, delayed secondary sex characteristics in 1.5% of males and 0.6% of females, motor disturbances in 1.17%, sensory disturbances in 0.91%, intellectual and learning disabilities in 2.48%, abnormal findings in routine neurologic examinations in 1.31%, EEG abnormalities in 4.30%, brain CT abnormalities in 5.09% and cardiac dysfunction in 1.07%. Various other disorders were seen in 20 patients. Many of these delayed adverse sequelae are caused by or related to central nervous system prophylaxis and systemic combination chemotherapy. The results suggest that it is needed to improve therapeutic methods through the stratification of patients by risk factors and detailed analysis of prognostic factors. Moreover it is important to render medical and psychosocial support to long-term survivors of childhood leukemia through interactions between the patient, parents and medical staff.     

急性心肌梗塞静脉溶栓治疗冠脉再通者早期ST段再抬高的临床意义

急性心肌梗塞早期静脉溶栓治疗后，一些溶栓再通患者中，可见早期降低的ＳＴ段再度出现抬高现象。本文回顾溶栓成功者８１例，其中早期出现ＳＴ段再度抬高者２１例（占３５％），与ＳＴ段非再度抬高者相比，ＣＰＫ、ＣＰＫ－ＭＢ峰值，心功能及院内死亡率等无显著差异。笔者认为，此现象也为再通的标志之一。因此，急性心肌梗塞溶栓治疗的早期连续监测心电图对确认再通与否非常重要
