Laparoscopic resection for Meckel's diverticulum causing intestinal obstruction.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal system with an estimated incidence of approximately 2% of the population. Although most cases are asymptomatic, it has the potential to create complications, such as hemorrhage, inflammation, intestinal obstruction, perforation, and intussusception. Meckel's diverticulum is generally diagnosed incidentally or upon investigation of unexplained gastrointestinal bleeding, perforation, inflammation, or obstruction for both pediatric and adult patients. Complications are often present as surgical emergencies and require resection of the diseased intestinal segment. In doubtful cases, laparoscopy should be the surgical method for both diagnosing and treating MD. Here we present a case of MD causing intestinal obstruction and that was treated by laparoscopic resection.

Retrospective evaluation of patients with elevated digoxin levels at an emergency department.

OBJECTIVES: We investigated the demographic characteristics, clinical and laboratory findings, treatment strategies and clinical outcomes of patients presenting at emergency department (ED) with digoxin levels at or above 1.2 ng/ml. MATERIALS AND METHODS: The demographic and clinical characteristics of patients with serum digoxin levels at or above 1.2 ng/ml admitted to an ED between January 2010 and July 2011 were investigated in this cross-sectional descriptive study. Patients with ECG and clinical findings consistent with digoxin toxicity and no additional explanation of their symptoms were evaluated for digoxin toxicity. RESULTS: In this study 137 patients were included, and 68.6% of patients were women with mean age 76.1 ± 12.2. There was no significant difference between gender and digoxin intoxication. The mean age of intoxicated group was significantly higher than the non-intoxicated group (P = 0.03). The most common comorbidities were congestive heart failure (n = 91) and atrial fibrillation (n = 74). The most common symptoms were nausea, vomiting and abdominal pain. The levels of hospitalization and mortality in this group were significantly higher. CONCLUSION: Digoxin intoxication must be suspected in patients present in the ED, particularly those with complaints that include nausea and vomiting, as well as new ECG changes; serum digoxin levels must be determined.

A rare entity in ED: Normal lipase level in acute pancreatitis.

Acute pancreatitis can have a variable presentation and diagnosis is based on clinical presentation, serum amylase and lipase levels and computed tomography. Negative predictive value of serum lipase in diagnosing acute pancreatitis is approximately to 100 percent and a normal blood lipase level in acute pancreatitis is an extremely rare condition. Here we reported two cases with normal serum amylase and lipase levels.

Bibliometric analysis of top 100 most-cited clinical studies on ultrasound in the Emergency Department.

STUDY OBJECTIVE: We identify and characterize the most highly cited articles related to ultrasonographic evaluations occurring in the emergency department. METHOD: We retrieved the top 100 articles in terms of citations pertaining to ultrasonographic evaluations in the emergency department from the Scopus database. We determined the number of citations of each article, the number of citations per year, the number of Google Scholar citations, the ultrasonographical study fields, the number of patients evaluated in each study, and the specialties of the researchers conducting the studies and ultrasonographies. We then used the ANOVA test to compare the multivariate groups. RESULTS: The median citation number of the articles in the Scopus database was 115 (range: 75-681), and the number of citations per year was 7.5 (range: 3.8-40.1). Focused assessment with sonography in trauma and non-traumatic abdominal ultrasonography were conducted in 32 and 13 studies, respectively. The primary authors were emergency medicine specialists in 46 studies. We found that vascular and lung ultrasonography studies were characterized by the largest number of citations per year. CONCLUSION: The most frequently cited studies conducted in the emergency department pertaining to the use of ultrasonography included a wide range of topics, and approximately half of the primary authors of these studies were emergency medicine specialists.

Laparoscopic splenectomy for a wandering spleen causing chronic pelvic pain.

Wandering spleen is a rare condition with a reported incidence of less than 0.5% in which the spleen migrates from its normal anatomical location to any other position in the abdomen. Women constitute 80% of cases and one third of the overall patients are children. It has different clinical presentations such as asymptomatic, painless mass in the abdomen, intermittent abdominal pain and acute abdomen due to torsion of the vascular pedicle. Here we present a case of wandering spleen causing chronic pelvic pain. Laparoscopic splenopexy was the treatment choice but it could not be performed due to huge size of the wandering spleen.

Recognizing acute appendicitis criteria on abdominal CT: do emergency physicians need a preliminary report?

BACKGROUND: Computed tomography (CT) is invaluable for the diagnosis of acute appendicitis (AA) in the emergency setting when used appropriately with proper risk stratification. The aim of this study is to investigate the capability and accuracy of emergency physicians (EPs) at recognizing AA criteria in intravenous contrast-enhanced abdominal CT and to investigate the level of interobserver agreement among them. METHODS: Consecutive patients who presented to Izmir University Hospital from January 1, 2014, to December 31, 2014, were evaluated. Patients with histopathologically confirmed AA and had intravenous contrast-enhanced abdominal CT were enrolled. Abdominal CT were interpreted by 4 EPs in a blind fashion. To compare differences in performances between observers, sensitivity, specificity, positive predictive value, negative predictive value, and κ values were calculated. The results were then compared with the radiology department's official reports. RESULTS: There were 48 patients eligible for the study. Among these patients, 19 were male (41%), with a mean age of 34.4 years (±11.3 years). Five patients were CT-negative appendicitis according to official radiology reports that were accepted as the criterion standard. The best sensitivity and negative predictive values were achieved at criterion "enlargement of the appendix," whereas the least sensitivity was for criterion "lack of opacification in an enlarged appendix." CONCLUSIONS: The recognition of the CT criteria for AA among EPs is substantial at best, and their ability to recognize the primary criteria for diagnosing AA is good. Emergency physicians have to gain a higher level of expertise to use this invaluable diagnostic tool more efficiently.

Inter-Observer Agreement on Diffusion-Weighted Magnetic Resonance Imaging Interpretation for Diagnosis of Acute Ischemic Stroke Among Emergency Physicians.

OBJECTIVES: Diffusion-weighted magnetic resonance imaging (DW-MRI) is a highly sensitive tool for the detection of early ischemic stroke and is excellent at detecting small and early infarcts. Nevertheless, conflict may arise and judgments may differ among different interpreters. Inter-observer variability shows the systematic difference among different observers and is expressed as the kappa (Κ) coefficient. In this study, we aimed to determinate the inter-observer variability among emergency physicians in the use of DW-MRI for the diagnosis of acute ischemic stroke. METHODS: Cranial DW-MRI images of 50 patients were interpreted in this retrospective observational cross-sectional study. Patients who were submitted to DW-MRI imaging for a suspected acute ischemic stroke were included in the study, unless the scans were ordered by any of the reviewers or they were absent in the system. The scans were blindly and randomly interpreted by four emergency physicians. Inter-observer agreement between reviewers was evaluated using Fleiss' Κ statistics. RESULTS: The mean kappa value for high signal on diffusion-weighted images (DWI) and for reduction on apparent diffusion coefficient (ADC) were substantial (k=0.67) and moderate (k=0.60) respectively. The correlation for detection of the presence of ischemia and location was substantial (k: 0.67). There were 18 false-positive and 4 false-negative evaluations of DWI, 15 false positive and 8 false-negative evaluations of ADC. CONCLUSIONS: Our data suggest that DW-MRI is reliable in screening for ischemic stroke when interpreted by emergency physicians in the emergency department. The levels of stroke identification and variability show that emergency physicians may have an acceptable level of agreement.

Acute pancreatitis due to extracorporeal shock wave lithotripsy: a rare complication.

Extracorporeal shock wave lithotripsy (ESWL) is considered the treatment of choice for most renal and upper ureteral stones. Although extensive data have documented its safety, serious complications have been reported in 1% of patients, including acute pancreatitis, perirenal hematoma, urosepsis, venous thrombosis, biliary obstruction, bowel perforation, lung injury, and rupture of aortic aneurysms. Here, we report a 41-year-old woman who underwent ESWL for a calculus at the right renal pelvis and immediately developed acute pancreatitis after the procedure. Although the possibility of post-ESWL acute pancreatitisis extremely low, physicians must be aware of this complication in emergency departments.

Spontaneous Bladder Rupture and Pelvic Fracture Due To Bladder Cancer.

Bladder rupture is a rare complication following bladder cancer, but has a high mortality rate. Since bladder rupture is an emergency, the diagnosis and treatment of the cancer is usually delayed. Here we report a 56-year-old male patient who presented to our emergency department with severe abdominal pain, abdominal distension, left leg pain and difficulty in walking without history of significant trauma and ended up with diagnoses of spontaneous bladder rupture and non-traumatic pelvic fracture caused by bladder carcinoma.

An unusual cause of death: spontaneous urinary bladder perforation.

Spontaneous urinary bladder perforation is a rare and life-threatening condition similar to traumatic and iatrogenic perforation. The connection with the underlying bladder damage due to previous radiotherapy, inflammation, malignancy, obstruction, or other causes can be found in almost all cases. The symptoms are often nonspecific, and misdiagnosis is common. Here, we present a case of spontaneous urinary bladder perforation due to bladder necrosis in a diabetic woman. She presented to the emergency department with abdominal pain. Exploratory laparotomy was performed by surgeons and revealed necrosis of the anterior and lateral walls of the urinary bladder. Microscopic examination revealed necrotic changes throughout the bladder wall. Ghost-like cellular outlines were compatible with coagulative necrosis. Clusters of bacteria were also present in some necrobiotic tissues. Malignant cells were not present. It appears probable that the infection was due to local interference with the blood supply (arterial, capillary, or venous) combined with the systemic metabolic upset that led to the bladder condition. In our case, we observed partial necrosis of the bladder rather than distortion of the entire blood supply to the bladder as consequences of the microvascular effects of diabetes. Urinary bladder perforation must be considered in the differential diagnosis of patients presenting with free fluid in the abdomen/peritonitis, decreased urine output, and hematuria, and in whom increased levels of urea/creatinine are detected in serum and/ or peritoneal fluid aspirate.

Ability of emergency physicians to detect early ischemic changes of acute ischemic stroke on cranial computed tomography.

OBJECTIVE: The objective of this study was to evaluate the ability of emergency physicians (EPs) to diagnose early ischemic changes due acute ischemic stroke on cranial computed tomography (CT). SUBJECTS AND METHODS: Three EPs interpreted CT scans obtained within 3 h of symptom onset in 50 patients with acute stroke. The CT scans were interpreted by the EPs and compared to official neuroradiologist reports as a gold standard. ĸ statistics were calculated to determine agreement among the three readers. Sensitivities and specificities were analyzed for each reader. RESULTS: The EPs' sensitivities were 50, 45.5, and 45.5%, and specificities were 64.3, 82.1, and 64.3%, respectively. Focal parenchymal hypodensity was the criterion for which the EPs were the most sensitive (77.3%). The ability of EPs to recognize early ischemic changes on CT scans in acute ischemic stroke was moderate based on sensitivities. CONCLUSION: Based on this study, EPs must be trained especially for recognizing early ischemic changes in acute ischemic stroke to improve their accuracy of interpretation.

Comparison of existing syncope rules and newly proposed anatolian syncope rule to predict short-term serious outcomes after syncope in the Turkish population.

BACKGROUND: We wished to compare the San Francisco Syncope Rule (SFSR), Evaluation of Guidelines in Syncope Study (EGSYS) and the Osservatorio Epidemiologico sulla Sincope nel Lazio (OESIL) risk scores and to assess their efficacy in recognising patients with syncope at high risk for short-term adverse events (death, the need for major therapeutic procedures, and early readmission to the hospital). We also wanted to test those variables to designate a local risk score, the Anatolian Syncope Rule (ASR). METHODS: This prospective, cohort study was conducted at the emergency department of a tertiary care centre. Between December 1 2009 and December 31 2010, we prospectively collected data on patients of ages 18 and over who presented to the emergency department with syncope. RESULTS: We enrolled 231 patients to the study. A univariate analysis found 23 variables that predicted syncope with adverse events. Dyspnoea, orthostatic hypotension, precipitating cause of syncope, age over 58 years, congestive heart failure, and electrocardiogram abnormality (termed DO-PACE) were found to predict short-term serious outcomes by logistic regression analysis and these were used to compose the ASR. The sensitivity of ASR, OESIL, EGSYS and SFSR for mortality were 100% (0.66 to 1.00); 90% (0.54 to 0.99), 80% (0.44 to 0.97) and 100% (0.66 to 1.00), respectively. The specificity of ASR, OESIL, EGSYS and SFSR for mortality were 78% (0.72 to 0.83); 76% (0.70 to 0.82); 80% (0.74 to 0.85) and 70% (0.63 to 0.76). The sensitivity of ASR, OESIL, EGSYS and SFSR for any adverse event were 97% (0.85 to 1.00); 70% (0.52 to 0.82); 56% (0.40 to 0.72) and 87% (0.72 to 0.95). The specificity of ASR, OESIL, EGSYS and SFSR for any adverse event were 72% (0.64 to 0.78); 82% (0.76 to 0.87); 84% (0.78 to 0.89); 78% (0.71 to 0.83), respectively. CONCLUSION: The newly proposed ASR appears to be highly sensitive for identifying patients at risk for short-term serious outcomes, with scores at least as good as those provided by existing diagnostic rules, and it is easier to perform at the bedside within the Turkish population. If prospectively validated, it may offer a tool to aid physicians' decision-making.
