Abstract
PURPOSE The purpose of the study was to evaluate the efficacy and safety of percutaneous drainage for palliation of symptoms and sepsis in patients with cystic or necrotic tumors in the abdomen and pelvis. MATERIALS AND METHODS This is a single center retrospective study of 36 patients (18 men, mean age = 51.1 years) who underwent percutaneous drainage for management of cystic or necrotic tumors in the non-postoperative setting over an 11-year period. Nineteen patients with intraabdominal fluid collections associated with primary malignancies included: cervical (n = 7), colorectal (n = 3), urothelial (n = 3), and others (n = 6). The 17 patients with fluid collections associated with intraabdominal metastases stemmed from the following primary malignancies: oropharyngeal squamous cell carcinoma (n = 3), colorectal (n = 3), ovarian (n = 2), lung (n = 2), melanoma (n = 2) along with others (n = 5). Indications for percutaneous drainage were as follows: pain (36/36; 100%); fever and/or leukocytosis (34/36; 94%), and mass effect (21/36; 58%). Seven patients underwent additional sclerosis with absolute alcohol. Criteria for drainage success were temporary or definitive relief of symptoms and sepsis control. RESULTS Successful sepsis control was achieved in all patients with sepsis (34/34; 100%) and 30/36 (83%) patients had improvement in pain. Duration of catheterization ranged from 2 to 90 days (mean = 22 days). There were four cases of fluid re-accumulation and one patient developed catheter tract seeding. Alcohol ablation was successful in two patients (2/7; 29%). Nearly all patients (34/36; 94%) died during the follow-up period. CONCLUSIONS Percutaneous drainage was effective for palliative treatment of symptomatic cystic and necrotic tumors in the majority of patients in this series.

Abstract
Intraabdominal fluid collections can be a significant cause of morbi-mortality among patients with acute pancreatitis and those who underwent surgery, especially oncological ones. Nowadays, the treatment tends to be minimally invasive, so that the patient's recovery would be shorter and the quality of life higher. EUS (endoscopic ultrasound) has emerged in the last decade to fulfill that demand, alongside percutaneous and surgical drainage in the management of perigastric collections. Objectives: The main objective of this paper is to evaluate the efficacy of EUS guided drainage in terms of techincal and clinical success. Secondary objectives refer to the assessment of complete resolution of intraabdominal collection, presence of infection after drainage, overall survival. Methods: We conducted a prospective study by enrolling 31 patients who were diagnosed using EUS with perigastric intraabdominal fluid collections, from an overall of 788 EUS performed over a period of 2 years. We analyzed their evolution during 6 months after treatment, by regular examinations (ultrasound/endoscopic/computed tomography). All of them were in-patients of Bucharest Clinical Emergency Hospital, either in Endoscopy or in Surgery Departments. Data collected was processed in IBM SPSS Statistics 20. Results: Overall mean age was 51 year and intraabdominal collections average was 109 mm (range 34 250 mm) and was correlated with the method of treatment (p 0.005). Patients underwent different methods for their intraabdominal collections: EUS drainage, CT (computed-tomography)- guided percutaneous drainage, surgical intervention, alone or combined when needed. Overall mortality was 9,3% and was mainly related to the severity of the case and sepsis. Conclusions: We conclude that endoscopic ultrasound can be the first choice for drainage of intraabdominal perigastric fluid collections because it is a safe and effective technique with 100 % technical success, and with over 80 % clinical success assures a better quality of life. For collections with a diameter larger than 127 mm, we can expect however the need of combined treatment, EUS and surgery.

Abstract
RATIONALE Critical care ultrasound identifies the signs of free intraperitoneal air and echogenic free fluid always indicates hollow viscus perforation (HVP) and needs immediate surgical interventions. However, in rare cases, these classic signs may also mislead proper clinical decisions. We report perforated viscus associated large peritoneal effusion with initial critical care ultrasound findings, whereas computed tomography (CT) examination confirmed a giant stomach due to superior mesenteric artery syndrome (SMAS). PATIENT CONCERNS A 70-year-old man was admitted to our emergency department with a complaint of recurrent vomiting with coffee ground emesis for 15 hours and worsen with hypotension for 6 hours. During gastric tube placement, the sudden cardiac arrest occurred. With 22 minutes resuscitation, sinus rhythm was restored. DIAGNOSES Quick ultrasound screen showed large echogenic fluid distributed in the whole abdomen. Diagnostic paracentesis collected "unclotted blood" and combined with a past history of duodenal ulcer, HVP was highly suspected. However, surgical intervention was not performed immediately as unstable vital signs and unfavorable coma states. After adequate resuscitation in intensive care unit, the patient was transferred to perform enhanced CT. Surprisingly, there was no evidence of HVP. Instead, CT showed a giant stomach possibly explained by SMAS. INTERVENTIONS Continuous gastric decompression was performed and 3100 mL coffee ground content was drainage within 24 hours of admission. OUTCOMES Abdominal distension was significantly relieved with improved vital signs. However, as the poor neurological outcome, family members abandon further treatment, and the patient died. LESSONS SMAS is a rare disorder, characterized by small bowel obstruction and severe gastric distension. Nasogastric tube insertion should be aware to protect airway against aspiration. Caution should be utilized to avoid over interpretation of ultrasonography findings on this condition.

Abstract
BACKGROUND Patients with adhesive small bowel obstruction (ASBO) often develop intraabdominal free fluid (IFF). While IFF is a finding on abdominopelvic computed tomography (CT) associated with the need for surgical intervention, many patients with IFF can be still managed non-operatively. A previous study suggested that a higher red blood cell count of IFF is highly predictive of strangulated ASBO. We hypothesized that radiodensity in IFF (Hounsfield unit (HU)) on CT would predict the need for surgical intervention. STUDY DESIGN Patients with clinicoradiological evidence of ASBO between January 2009 and December 2013 were identified. In patients with IFF > 3 cm2 identified on CT, the HU was measured in the largest pocket of IFF. A sensitivity analysis was performed to determine a high-density HU threshold. The HU of patients who underwent therapeutic laparotomy was compared with those successfully discharged with non-operative management. RESULTS A total of 318 patients with ASBO (median age 52 years, 56.0 % male) were identified. Of 111 patients who had IFF on CT, 55.9 % underwent therapeutic laparotomy and 15.3 % required bowel resection. Radiodensity of IFF in the operative group was significantly higher than that in the non-operative group (18.2 vs. 7.0 HU, p < 0.01). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of high-density IFF (>10 HU) to predict the need for surgical intervention were 83.9, 65.3, 75.4, 76.2, and 75.6 %, respectively. CONCLUSIONS High-density IFF on CT was significantly associated with the need for surgical intervention in patients with ASBO. Prospective study to validate the predictive value of high-density IFF on CT will be warranted.

Abstract
This research presents investigation results of the diagnostic efficiency of an azimuthally stable Mueller-matrix method of analysis of laser autofluorescence of polycrystalline films of dried uterine cavity peritoneal fluid. A model of the generalized optical anisotropy of films of dried peritoneal fluid is proposed in order to define the processes of laser autofluorescence. The influence of complex mechanisms of both phase (linear and circular birefringence) and amplitude (linear and circular dichroism) anisotropies is taken into consideration. The interconnections between the azimuthally stable Mueller-matrix elements characterizing laser autofluorescence and different mechanisms of optical anisotropy are determined. The statistical analysis of coordinate distributions of such Mueller-matrix rotation invariants is proposed. Thereupon the quantitative criteria (statistic moments of the first to the fourth order) of differentiation of polycrystalline films of dried peritoneal fluid, group 1 (healthy donors) and group 2 (uterus endometriosis patients), are determined.

Abstract
Results of examination and treatment of 60 patients, suffering pancreatogenic limited liquid accumulations (LLA) were analyzed, of them in 53 — a puncture—draining interventions (PDI) were made under ultrasonographic investigation (USI), 7 — were treated without surgical intervention. For the LLA maturity estimation important significance have their form, and еchogenicity, presence of vascular signals in the wall. Conservative therapy have appeared more effective while presence of a septic LLA, having diameter up to 5 cm without a wall formatted. Less mature are LLA, more probability exists of their regress after PDI, made under ultrasonographic control.

Abstract
OBJECTIVES Crimean-Congo hemorrhagic fever (CCHF) has been endemic in Turkey since 2002. Some radiologic findings are considered common by clinicians and radiologists. In this regard, we aimed to assess the sonographic findings in patents with CCHF in a pilot study to obtain basic knowledge for planning further controlled studies. METHODS An observational descriptive study was planned. Patients with a CCHF diagnosis monitored by the infectious diseases department of a tertiary care hospital were included. Sonographic examinations were conducted by 2 radiologists for each patient, and the findings were recorded. RESULTS Twenty-five patients with CCHF were included. Hepatomegaly (40%), splenomegaly (28%), paraceliac lymphadenopathy (48%), gallbladder wall thickening (36%), increased echogenicity in the renal parenchyma (40%), and fluid/effusion in the perihepatic, perisplenic, pleural, and hepatorenal recesses of the subhepatic space (Morison pouch) as well as between the intestinal loops (52%) were the primary findings. A decrease in the gallbladder wall thickening and limited resorption of intraperitoneal and pleural effusion were noted during follow-up. CONCLUSIONS Hepatosplenomegaly, paraceliac lymphadenopathy, and gallbladder wall thickening as well as intraperitoneal and pleural effusion were the primary findings in CCHF, and they became prominent on the third day of the disease in some patients. The relationship between sonographic findings and disease severity will be investigated in an upcoming study.

Abstract
OBJECTIVES The aim of this study was to detect the onset, evolution, and meaning of extraluminal free fluid in a rat model of small-bowel obstruction using high-frequency microsonography. METHODS Small-bowel obstruction was surgically created in 8 rats divided into 2 groups of 4 rats each. All rats were examined by high-frequency microsonography to monitor the evolution of small-bowel obstruction and the abdominal sonographic findings. In group 2 rats, the obstruction was resolved 2 hours after surgery. RESULTS In all rats, free peritoneal fluid was detected just near the obstructed loop after 1 hour and in the hepatorenal recess after 2 hours. These features progressively increased in the following hours in group 1 rats. In group 2, the amount of free fluid decreased shortly after removing the obstruction. CONCLUSIONS Free fluid is an early finding in small-bowel obstruction, and the increase or decrease of its amount is correlated with the worsening or resolution of the obstruction.

Abstract
OBJECTIVE This study investigated the occurrence of peritoneal fluid in women undergoing intrauterine insemination (IUI) and its correlation with the stage of pelvic endometriosis and its influence on pregnancy outcomes. MATERIALS AND METHODS A retrospective case-control design was used to recruit 272 infertile women with pelvic endometriosis. The treatment protocol consisted of controlled ovarian hyperstimulation with downregulation and gonadotropin for IUI treatment following ultrasound and laparoscopic intervention. The amount and color of the peritoneal fluid were determined during laparoscopy. RESULTS The mean amount of peritoneal fluid with pelvic endometriosis that was detected using transvaginal ultrasound was ~ 15.1 mL. Women whose cycles contained more peritoneal fluid had significantly lower pregnancy rates (17.2% and 31.3%, respectively). The total clinical pregnancy rate was not significantly different between the two groups with reddish and yellowish peritoneal fluid who had pelvic endometriosis. CONCLUSION Pelvic endometriosis and peritoneal fluid, detected through vaginal ultrasound, have negative effects on the pregnancy outcome of IUI treatment.

Abstract
OBJECTIVES The presence of free intraperitoneal fluid on diagnostic imaging (sonography or computed tomography [CT]) may indicate an acute inflammatory process in children with abdominal pain in a nontraumatic setting. Although clinical outcomes of pediatric trauma patients with free fluid on diagnostic examinations without evidence of solid-organ injury have been studied, similar studies in the absence of trauma are rare. Our objective was to study clinical outcomes of children with acute abdominal pain of nontraumatic etiology and free intraperitoneal fluid on diagnostic imaging (abdominal/pelvic sonography, CT, or both). METHODS We conducted a retrospective review of medical records of children aged 0 to 18 years presenting to a pediatric emergency department with acute abdominal pain (nontraumatic) between April 2008 and March 2009. Patients with intraperitoneal free fluid on imaging were divided into 2 groups: group I, imaging suggestive of an intra-abdominal surgical condition such as appendicitis; and group II, no evidence of an acute surgical condition on imaging, including patients with equivocal studies. Computed tomograms and sonograms were reviewed by a board-certified radiologist, and the free fluid volume was quantitated. RESULTS Of 1613 patients who underwent diagnostic imaging, 407 were eligible for the study; 134 (33%) had free fluid detected on diagnostic imaging. In patients with both sonography and CT, there was a significant correlation in the free fluid volume (r = 0.79; P < .0005). A significantly greater number of male patients with free fluid had a surgical condition identified on imaging (57.4% versus 25%; P < .001). Children with free fluid and an associated condition on imaging were more likely to have surgery (94.4% versus 6.3%; P < .001). CONCLUSIONS We found clinical outcomes (surgical versus nonsurgical) to be most correlated with a surgical diagnosis on diagnostic imaging and not with the amount of fluid present.

Abstract
Roux-en-Y gastric bypass (RYGBP) is an increasingly used procedure when treating morbid obesity. Due to the extensive gastrointestinal rearrangement, diagnostic evaluation of patients with gastric bypass and acute abdominal pain can be difficult. We present a case of a perforated duodenal ulcer in a RYGBP operated patient, where free abdominal fluid, but hardly any pneumoperitoneum was seen on a computed tomography. Free intraperitoneal fluid is an important finding and should give suspicion of the need for emergency surgery in RYGBP operated patients with abdominal pain.

Abstract
OBJECTIVES Free intraperitoneal fluid is a secondary sign of abdominal disorders. The detection of small volumes of fluid has been documented as a normal finding in women of childbearing age and also in pediatric sonography. However, the finding of free fluid in asymptomatic men has not been similarly documented by sonography. We postulate that with high-frequency linear probes, small volumes of fluid may be detected in asymptomatic men without underlying abdominal disorders. METHODS Ten healthy male volunteers underwent targeted abdominal sonographic examinations after an overnight fast and in an immediate postprandial state. The findings were documented, and representative images were saved for analysis. RESULTS We found small slivers or geometric collections of fluid between bowel loops in 4 of the 10 volunteers. No obvious correlation between the detection of fluid and the nutritional or hydration status of the patient was identified. CONCLUSIONS The findings suggest that small volumes of pelvic free fluid in healthy men can be normal and do not necessarily indicate underlying disorders. The role of free fluid identification as an indicator of major intra-abdominal disorders must be viewed with caution and with careful clinical correlation.

Abstract
INTRODUCTION Enteric fever is a common infection in endemic areas; however, there are few reports describing the computed tomography (CT) manifestations of enteric fever. We aim to describe and illustrate CT findings in enteric fever in this study. MATERIALS AND METHODS A retrospective search of medical records in our institute for patients with positive blood cultures for Salmonella typhi, and Salmonella paratyphi organisms yielded 39 cases. Among these patients, 12 had undergone a CT study of the abdomen. The CT images, laboratory and clinical findings of these 12 patients were reviewed. RESULTS The most common clinical presentation was fever (100%). Typical features of gastroenteritis were present in only over half of the patients. Liver function tests were abnormal in all patients. The most common abdominal manifestations on CT were the presence of mesenteric lymphadenopathy and splenomegaly (75%). Other features were circumferential small bowel wall thickening (58.3%) and free intraperitoneal fluid (50%). Three patients were found to have complications; one with bleeding from terminal ileal ulceration, another with an ileal perforation and the third with renal abscess formation. CONCLUSION CT is useful in evaluating enteric fever in patients with severe forms of presentation, a longer clinical course or less specific symptoms. Although the imaging features overlap with other abdominal infections, when combined with clinical features, travel history to endemic areas and presence of transaminitis, the diagnosis of enteric fever should be considered. CT in particular, is useful for the detection of complications such as perforation, bleeding and abscess formation.

Abstract
The purpose of this study was to test the hypothesis that with improved technology, the presence of abscess in a postoperative fluid collection may be prospectively made. This is an Institutional Review Board-approved, Health Insurance Portability and Accountability Act-compliant retrospective review of computed tomography (CT)-guided intra-abdominal fluid collection drainages. The diagnostic CT scans of 95 consecutive patients performed on 16- and 64-multidetector CT (MDCT) were reviewed by four readers with varying abdominal imaging expertise. Readers were asked to determine fluid content, to document whether infection was present, and to rate reader confidence for infection. A fifth radiologist reviewed the collections for imaging characteristics. The gold standard for presence of infection was microbiological Gram stain and culture. The logistic regression model showed that both fluid collections containing gas or high attenuation fluid (average CT density 20 or greater Hounsfield units) are significant predictors of infection (P = 0.001). The average sensitivity over the four readers for determining presence of infection was 83.4 per cent and specificity was 39.3 per cent. Even in the era of MDCT, the ability to predict whether or not a fluid collection is infected or not, based on imaging findings alone, is limited. Presence of gas is a strong indicator of infection, but no imaging finding is characteristic of a sterile fluid collection.

Abstract
BACKGROUND Free intraperitoneal fluid can be an important sign in an abdominal inflammatory process or abdominal trauma. It is often present in children with abdominal pain, but it is a nonspecific finding. A minimal amount of free intraperitoneal fluid is considered normal. OBJECTIVE The purpose of this study was to evaluate the incidence, location and volume of free fluid in the abdomen and pelvis in a population of asymptomatic children. MATERIALS AND METHODS In this prospective study, we performed clinically indicated abdominal and pelvic sonography, using high-resolution transducers, in 200 asymptomatic children: 104 (52%) girls, 96 (48%) boys; ages 6 days-15 years (mean 3 years 8 months). US studies were performed and prospectively evaluated by two experienced pediatric radiologists. Patients with any condition that could result in the accumulation of free intraperitoneal fluid as well as postpubertal girls were excluded from the study. RESULTS Free intraperitoneal fluid was seen in 12 children (6%), only in the pelvis. Fluid volume never exceeded 1 ml. CONCLUSION Our study suggests that 1 ml or less of free intraperitoneal fluid detected in the pelvis is probably insignificant.

Abstract
BACKGROUND Our objective was to evaluate the accuracy of paramedic-performed Focused Assessment with Sonography in Trauma (PFAST) for detection of free fluid in patients admitted to the Emergency Department (ED) following trauma. METHODS After four hours of didactic and four hours of hands-on training, four paramedics prospectively evaluated trauma patients. Our gold standard was the official radiologist reports of ultrasonography and computerized abdominal tomography (CAT). The sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio of PFAST were calculated and analyzed using SPSS 15.0 with ?2 testing. RESULTS One hundred and twenty-seven patients were evaluated by the paramedics. Fourteen patients had positive free fluid in the abdomen. Of these, 11 were corroborated by radiology reports and CAT (true positives), and three were found to be negative (false positives). In 113 cases, PFAST was negative for free fluid. Of these, 111 were determined not to have free fluid (true negatives), whereas free fluid was detected by CAT in 2 (false negatives). The sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio of PFAST were 84.62, 97.37, 32.15, 0.16, and 203.50, respectively. CONCLUSION Our study shows that paramedics can perform FAST in hospital Eds with a high degree of accuracy.

Abstract
BACKGROUND Proper management of small bowel obstruction (SBO) requires a methodology to prevent nontherapeutic laparotomy while minimizing the chance of overlooking strangulation obstruction causing intestinal ischemia. Our aim was to identify preoperative risk factors associated with strangulating SBO and to develop a model to predict the need for operative intervention in the presence of an SBO. Our hypothesis was that free intraperitoneal fluid on computed tomography (CT) is associated with the presence of bowel ischemia and need for exploration. METHODS We reviewed 100 consecutive patients with SBO, all of whom had undergone CT that was reviewed by a radiologist blinded to outcome. The need for operative management was confirmed retrospectively by four surgeons based on operative findings and the patient's clinical course. RESULTS Patients were divided into two groups: group 1, who required operative management on retrospective review, and group 2 who did not. Four patients who were treated nonoperatively had ischemia or died of malignant SBO and were then included in group 1; two patients who had a nontherapeutic exploration were included in group 2. On univariate analysis, the need for exploration (n = 48) was associated (p < 0.05) with a history of malignancy (29% vs. 12%), vomiting (85% vs. 63%), and CT findings of either free intraperitoneal fluid (67% vs. 31%), mesenteric edema (67% vs. 37%), mesenteric vascular engorgement (85% vs. 67%), small bowel wall thickening (44% vs. 25%) or absence of the "small bowel feces sign" (so-called fecalization) (10% vs. 29%). Ischemia (n = 11) was associated (p < 0.05 each) with peritonitis (36% vs. 1%), free intraperitoneal fluid (82% vs. 44%), serum lactate concentration (2.7 +/- 1.6 vs. 1.3 +/- 0.6 mmol/l), mesenteric edema (91% vs. 46%), closed loop obstruction (27% vs. 2%), pneumatosis intestinalis (18% vs. 0%), and portal venous gas (18% vs. 0%). On multivariate analysis, free intraperitoneal fluid [odds ratio (OR) 3.80, 95% confidence interval (CI) 1.5-9.9], mesenteric edema (OR 3.59, 95% CI 1.3-9.6), lack of the "small bowel feces sign" (OR 0.19, 95% CI 0.05-0.68), and a history of vomiting (OR 4.67, 95% CI 1.5-14.4) were independent predictors of the need for operative exploration (p < 0.05 each). The combination of vomiting, no "small bowel feces sign," free intraperitoneal fluid, and mesenteric edema had a sensitivity of 96%, and a positive predictive value of 90% (OR 16.4, 95% CI 3.6-75.4) for requiring exploration. CONCLUSION Clinical, laboratory, and radiographic factors should all be considered when making a decision about treatment of SBO. The four clinical features-intraperitoneal free fluid, mesenteric edema, lack of the "small bowel feces sign," history of vomiting-are predictive of requiring operative intervention during the patient's hospital stay and should be factored strongly into the decision-making algorithm for operative versus nonoperative treatment.

Abstract
OBJECTIVE To assess the accuracy of the assessment of peritoneal fluid volumes of up to 1 L by transvaginal ultrasonography and to re-evaluate the formula used to calculate total volume from the dimensions of the largest pocket. METHODS Patients (n = 13) enrolled for a minor laparoscopic procedure were prospectively recruited. At the end of the procedure, with the patient in the 30 degrees anti-Trendelenburg position, Ringer's lactate was instilled into the abdomen in discrete steps up to 1 L. Following equilibration the diameters of the single pocket of fluid were measured by transvaginal ultrasonography in order to calculate the volume, and regression models were used to determine the relationship between this and the instilled volume. The body mass index (BMI) of the patient was evaluated as a parameter for predicting the instilled volume more accurately. RESULTS The intra-abdominal fluid volume could be calculated from the measured volume using a quadratic regression equation with an overall coefficient of variation of 19%. In individual patients, changes in volume could be assessed with a coefficient of variation of 7.3%. BMI was not found to be a significant parameter in relating the measured to the instilled volume. CONCLUSION Transvaginal ultrasound in a standardized setting can accurately estimate the volume of peritoneal fluid, with the accuracy consistent for small and large volumes. Changes in peritoneal fluid volume over time in the same individual can be measured more accurately than the total volume present.

Abstract
PURPOSE To investigate the correlation between the 'smallest fluid depth' (SFD) measured on sonography (US) at the 'paracentesis pocket' with the amount of fluid drained in patients referred for US-guided large-volume paracentesis. METHODS US examinations performed to guide 60 paracenteses in 29 patients with large-volume ascites were reviewed and the SFD measured at the site of the paracentesis. The SFD was measured from the most superficial bowel loop to the abdominal wall. The SFD measurements were compared with the drained fluid volume (DFV) measurements. RESULTS The average DFV per paracentesis was 5.2 L with an average SFD measurement of 5.4 cm. For every 1-cm increase in the measured SFD, there was an average 1-L increase in the DFV. After applying this relationship to the measured depth in each case, the comparison between the estimated fluid volume (EFV) on US and the DFV demonstrated a <1-L difference in 38 of 60 paracenteses (63.3%) and a <2-L difference in 51 of 60 paracenteses (85%). CONCLUSION The SFD measured at the site of paracentesis shows a correlation with the drained fluid volume and can be used for fluid volume estimation on US.

Abstract
INTRODUCTION Bedside ultrasonography is a modern and progressive examinating method. During the past two decades, performing of bedside ultrasonography has repeteadly shown its clinical and economical advantages. Bedside ultrasonography appears to be cost-effective method which provides minimall patient and staff stress. AIM AND METHOD 132 critically ill patients were involved, regardless of basic diagnosis and surgical procedure they undervent. In these patients both bedside USG and CT were performed in order to prove a fluid collections in one of the following anatomical locations pleural cavity, peritoneal cavity and abdominal wall. The prospective study assessed and compared sensitivity of bedside USG to CT. Results of the study should by further applied in hardly transportable critically ill, for that CT could be hazardous. RESULTS AND CONCLUSION Bedside USG had comparable sensitivity to CT in fluidothrorax and abdominal wall colections detection, in some cases even more. For intraabdominal fluid USG represent less accurate method to CT, benefit of CT should be then discussed in each patient individually considering general health condition and basic diagnosis.

Abstract
BACKGROUND Predicting the clinical course in adhesional small bowel obstruction is difficult. There are no validated clinical or radiologic features that allow early identification of patients likely to require surgical intervention. METHODS We conducted a retrospective review of 100 patients consecutively admitted to a tertiary level teaching hospital over a 3-year period (2002-2004) who had acute adhesional small bowel obstruction and underwent computed tomography (CT). The primary outcomes that we assessed were conservative management or the need for surgical intervention. We investigated time to physiologic gastrointestinal function recovery as a secondary outcome. We examined independent predictors of surgical intervention in a bivariate analysis using a stepwise logistic regression analysis. RESULTS Of the 100 patients investigated, we excluded 12. Of the 88 remaining patients, 58 (66%) were managed conservatively and 30 (34%) underwent surgery. Peritoneal fluid detected on a CT scan (n = 37) was associated more frequently with surgery than conservative management (46% v. 29%, p = 0.046, chi(2)). Logistical regression identified peritoneal fluid detected on a CT scan as an independent predictor of surgical intervention (odds ratio 3.0, 95% confidence interval 1.15-7.84). CONCLUSION The presence of peritoneal fluid on a CT scan in patients with adhesional small bowel obstruction is an independent predictor of surgical intervention and should alert the clinician that the patient is 3 times more likely to require surgery.

Abstract
UNLABELLED Recurrent pelvi-abdominal multilocular fluid collections in female patients may be of various aetiology: infections, haemorrhage, benign or malignant tumours. PURPOSE Diagnosis of such fluid collections is complex, imaging examinations (ultrasonography, computed tomography, MRI) and biochemical, cytological and histological examinations must be included. Some cases, however, are difficult to diagnose, and their treatment is uncertain. MATERIALS AND METHODS We present the case of a 22-year-old unmarried female patient with minor symptoms, not correlated with a pelvi-peritoneal fluid collection extending into the infra-mesocolic space, revealed by ultrasonography and MRI. The aetiology was uncertain after biological examinations and cytology. The disease course was recurrent during 14 months, under anti-inflammatory treatment and surgical intervention with removal of the fluid (2.5 l), resection of the right ovary (histological examination revealed small ovarian mucinous cysts) and excision of a fibroma of the right utero-sacral ligament. Follow-up sonography was the chosen method for repeated diagnostic and therapeutic echo-guided punctures. Finally, after immuno-stimulating treatment, we observed almost complete remission of the peritoneal fluid collection. RESULTS This paper reveals significant discordances between the clinical appearance and the presence of a large peritoneal fluid collection, between locally recurrent appearance and cytological and histopathological "benign" results, between positive intradermal reaction to tuberculin and negative culture of B. Koch from aspirate. There were concordances between immune electrophoresis and some cytological elements and between three dimensional and panoramic SieScape ultrasonography and MRI. We must, however, note the superiority of MRI in the designation of anatomical findings and analysis of the histological structure. CONCLUSION The importance of this case is derived from the atypical clinical appearance and course, with uncertain aetiology after complex imaging, biological and surgical explorations.

Abstract
BACKGROUND There is little in the literature regarding the use of gray-scale and Doppler sonography of the bowel in necrotizing enterocolitis (NEC) and how findings depicted by this modality might assist in predicting outcome and influence management. OBJECTIVE To correlate sonographic findings with outcome in NEC. MATERIALS AND METHODS This was a retrospective analysis of clinical and abdominal ultrasonography (AUS) findings in NEC from January 2003 to December 2005. AUS findings were evaluated for portal venous gas, free gas, peritoneal fluid, bowel wall thickness, echogenicity, perfusion and intramural gas. Patients were categorized into two groups, according to their outcome. RESULTS A total of 40 infants were identified who had AUS for NEC prior to any surgical intervention. Group A comprised 18 neonates treated medically and recovered fully, and group B comprised 22 neonates who required surgery or died. Free gas (six patients) and focal fluid collections (three patients) were only found in group B. Increased bowel wall echogenicity, absent bowel perfusion, portal venous gas, bowel wall thinning, bowel wall thickening, free fluid with echoes and intramural gas were seen in both groups, but more frequently in group B. Anechoic free fluid was seen more frequently in group A. Increased bowel perfusion was seen equally in both groups. CONCLUSION An adverse outcome was associated with the sonographic findings of free gas, focal fluid collections or three or more of the following: increased bowel wall echogenicity, absent bowel perfusion, portal venous gas, bowel wall thinning, bowel wall thickening, free fluid with echoes and intramural gas. Sonographic findings are useful in predicting outcome and therefore might help guide management.

A 70-year-old woman presented at a local clinic because of shortness of breath. Since she was found to have pleural effusion, she was referred to our hospital for further evaluation. She had no history of trauma or surgery. Pleural effusion examination revealed a milky-white, chylous, odorless fluid with increased triglycerides. Further evaluation led to a diagnosis of idiopathic chylothorax. Althought she was found to have transudative ascites, abdominal ultrasonography and computed tomography revealed no significant findings including cirrhosis of the liver. As a result of intravenous hyperalimentation with fasting, the chylous pleural fluid became serous and decreased. Ascites disappeared simultaneously, suggesting a possible relationship between the chylothorax and transudative ascites.

Abstract
A 3-month-old male Golden Retriever puppy was evaluated for lethargy and fever of 2-days duration. Results of a CBC and biochemical profile revealed marked eosinophilia (6.3 X 10(3)/microL; reference interval 0.1-1.2 X 10(3)/microL), moderate thrombocytopenia, and increased activities of alanine aminotransferase, aspartate aminotransferase, and creatine kinase. Hepatomegaly and peritoneal effusion were found using abdominal ultrasound. Peritoneal fluid analysis revealed eosinophilic inflammation (23,000 nucleated cells/microL with 88% eosinophils). Despite supportive treatment the puppy's condition deteriorated rapidly; euthanasia was requested, and a necropsy performed. Microscopically, there was marked necrosuppurative and eosinophilic hepatitis with vasculitis. Numerous hepatocytes contained protozoal organisms suspected to be Toxoplasma gondii or Neospora caninum. However, serum was negative for both T gondii and N caninum antibodies; polymerase chain reaction assay on hepatic tissue was negative for both organisms; and immunohistochemical evaluation of hepatic tissue using serum raised against T gondii, N caninum, and Sarcocystis neurona also was negative. Schizont morphology suggested that merozoites replicated by endopolygeny, forming rosettes around a central residual body. Transmission electron microscopy revealed that merozoites lacked rhoptries. These findings were consistent with a diagnosis of Sarcocystis canis, an apicomplexan parasite with an unknown life cycle.

Abstract
Modalities available for the diagnosis of blunt abdominal traumatic (BAT) injuries include focused abdominal sonography for trauma, diagnostic peritoneal lavage, and computed tomography (CT) of the abdomen/pelvis. Hollow viscous and/or mesenteric injury (HVI/MI) can still be challenging to diagnose. Specifically, there is debate as to the proper management of BAT when CT findings include free peritoneal fluid but no evidence of solid organ injury (SOI). Our objective was to determine the incidence of HVI/MI and to evaluate the management of BAT patients with CT findings of peritoneal fluid without evidence of SOI. An Institutional Review Board-approved retrospective chart review was conducted of all BAT patients with peritoneal fluid on CT admitted to Kern Medical Center from January 1, 2003 to July 31, 2004. A total of 2651 trauma admissions yielded 79 patients. Fourteen of these had no evidence of SOI. Nonoperative management was successful in only 2 of these 14, whereas 12 required an operation, with 11 being therapeutic. Trigger to operate and time from presentation to laparotomy was hypotension in three patients (164 minutes), signs of HVI/MI on CT in two patients (235 minutes), diaphragm injury on CT in one patient (95 minutes), and for peritoneal signs in six patients (508 minutes). In BAT patients with peritoneal fluid on CT without evidence of SOI, there should be a high suspicion of HVI/MI. Relying on increasing abdominal tenderness to trigger laparotomy can result in delayed treatment.

Abstract
OBJECTIVE To evaluate the usefulness of ultrasonographic examinations as a diagnostic tool for emergency physicians in out-of-hospital settings. METHODS Prospective study performed in a French teaching hospital. Eight emergency physicians given ultrasound training for out-of-hospital diagnosis of pleural, peritoneal, or pericardial effusion; deep venous thrombosis; and arterial flow interruption. After clinical examination, a probability of diagnosis ("clinical score") was assigned on visual analog scale from 0 (absent lesion) to 10 (present lesion). Clinical score between 3 and 7 was considered as clinically doubtful. After ultrasound examination, a second probability ("ultrasound score") was similarly determined. Potential usefulness of ultrasound examination was evaluated by calculating the absolute difference between clinical and ultrasound scores. Patients were followed up to determine final diagnosis: present or absent lesion. "Ultrasound usefulness score" (USS) was determined attributing a positive (when ultrasonography increased diagnostic accuracy) or a negative (when ultrasonography decreased diagnostic accuracy) value to the absolute difference between clinical and ultrasound scores. RESULTS One hundred sixty-nine patients were included and 302 ultrasound examinations performed. Median duration of examination was 6 minutes (5-10 minutes). The suspected lesion was found in 45 cases (17%). Mean USS was +2 (0-4). Ultrasonographic examination improved diagnostic accuracy (ie, positive USS) in 181 (67%) cases, decreased it (ie, negative USS) in 22 (8%) cases, and was not contributive (ie, USS was 0) in 67 (25%) cases. When initial diagnosis was uncertain (n = 115), diagnostic performance reached +4 (3-5) and ultrasonographic examination improved diagnostic accuracy in 103 (90%) cases. CONCLUSION Out-of-hospital ultrasonography increased diagnostic accuracy in out-of-hospital settings.

Abstract
BACKGROUND Ultrasonography (US) has become indispensable in assessing the status of the injured patient. Although hand-held US equipment is now commercially available and may expand the availability and speed of US in assessing the trauma patient, it has not been subjected to controlled evaluation in early trauma care. METHODS A 2.4-kg hand-held (HH) US device was used to perform focused abdominal sonography for trauma (FAST) on blunt trauma victims at 2 centres. Results were compared with the "truth" as determined through formal FAST examinations (FFAST), CT, operative findings and serial examination. The ability of HHFAST to detect free fluid, intra-abdominal injuries and injuries requiring therapeutic interventions was assessed. RESULTS HHFAST was positive in 80% of 313 patients who needed surgery or angiography. HHFAST test performances (sensitivity, specificity, positive and negative predictive values, likelihood ratios of positive and negative test results) were 77%, 99%, 96%, 94%, 95%, 95 and 0.2, respectively, for free fluid, and 64%, 99%, 96%, 89%, 90%, 74 and 0.4, respectively, for documented injuries. HHFAST missed or gave an indeterminate result in 8 (3%) of 270 patients with injuries who required therapeutic intervention and 25 (9%) of 270 patients who did not require intervention. FFAST performance was comparable. CONCLUSIONS HHFAST performed by clinicians detects intraperitoneal fluid with a high degree of accuracy. All FAST examinations are valuable tests when positive. They will miss some injuries, but the majority of the injuries missed do not require therapy. HHFAST provides an early extension of the physical examination but should be complemented by the selective use of CT, rather than formal repeat US.

Abstract
OBJECTIVE To review the diagnostic imaging studies in patients with surgically proven uterine incisional necrosis/dehiscence complicating cesarean section and to compare these studies with the findings at surgery. STUDY DESIGN Over a 6-year period, the records of 7 patients with imaging studies prior to surgery for uterine incisional necrosis/dehiscence complicating cesarean delivery were reviewed and compared with the findings at surgery. RESULTS Four cases underwent computed tomography (CT) and sonography, 1 underwent CT only, and 2 underwent sonography only. Abnormal findings included abdominal free fluid in 4, pleural effusions in 3, dilated bowel in 3, possible bladder flap hematoma in 2 and single instances of liver abscess and retained products of conception. In no cases were all the studies normal, and necrosis/dehiscence was not demonstrated in any patient. CONCLUSION Abdominal free fluid, bowel distension, pleural effusion and bladder flap hematoma seen on CT or sonogram in the postcesarean context suggest the possibility of uterine incisional necrosis/dehiscence. Magnetic resonance imaging (MRI) might then be indicated since MRI may be superior to CT in evaluating complications at the incisional site because of its multiplanar capability and greater degree of soft tissue contrast.

Abstract
Patients presenting with hypotension may be evaluated with a FAST (Focused Abdominal Sonography for Trauma) examination as recent literature has suggested its utility in the unstable patient. Those who are found to have intraperitoneal fluid on the FAST examination may have solid organ injury from unknown trauma, ruptured abdominal aortic aneurysm (AAA), hemorrhaging ovarian cyst, ruptured ectopic pregnancy, or other disease process responsible for intra-periteal blood. However, because ultrasound does not assist in fluid identification, it is possible that the fluid present is not blood, but ascites. Further, a decision may need to be made regarding emergent surgical intervention or blood transfusion vs. aggressive fluid resuscitation or pressors followed by other testing such as computed tomography. This case series illustrates the utility of an ultrasound guided, emergent diagnostic paracentesis in the management of unstable patients found to have a positive FAST examination. Six unstable patients were evaluated with the FAST examination and found to have large quantities of intraperitoneal fluid. In each case the fluid was sampled and proposed management changed due to fluid identification.

Abstract
Endosonography ultrasound (EUS) is a minimally invasive technology using a high-frequency ultrasound transducer that is incorporated into the tip of a conventional endoscope. This technique permits high-resolution imaging of the gastrointestinal wall and structures in its vicinity, as well as real-time endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA). This is a review of the literature on EUS-guided FNA of the mediastinal and abdominal lymph nodes, the pancreas, intramural gastrointestinal masses, and other miscellaneous organs and body cavities. EUS-guided FNA is a recently developed procedure that has established itself as a safe, highly accurate, and clinically useful modality.

Abstract
OBJECTIVE To evaluate the importance of isolated pelvic free fluid (FF) detected by ultrasound examination in pregnant patients and in non-pregnant reproductive age women with blunt abdominal trauma (BAT). METHODS Reproductive age women aged 10-50 years who presented with BAT and underwent focused abdominal sonography for trauma (FAST) from January 1995 to June 2002 at a Level 1 trauma center were included. Patients were assigned to four groups according to the location of FF detected by ultrasound (Group 1, no FF; Group 2, FF in pelvis; Group 3, FF in abdomen; Group 4, FF in abdomen and pelvis). Ultrasound findings were compared with intra-abdominal and pelvic injuries detected by computed tomography and/or laparotomy. Pair-wise comparison was performed using a Fisher's exact test. RESULTS Ultrasound detection of FF in the abdomen alone or FF in the abdomen and pelvis was significantly associated with intra-abdominal injury (IAI) compared to those without FF (P < 0.001) for both pregnant and non-pregnant reproductive age women. FF isolated to the pelvis was also associated with a higher injury rate compared to no FF in pregnant women (30% vs. 3%, P = 0.005) and in non-pregnant reproductive age women (39.5% vs. 3.7%, P < 0.001). CONCLUSIONS In reproductive age women with BAT, ultrasound detection of FF in the abdomen alone, in both the abdomen and pelvis, or isolated to the pelvis is associated with a higher IAI rate. Therefore, isolated FF in the pelvis should not necessarily be considered physiological in pregnant and non-pregnant patients with BAT.

Abstract
This is the second of a two-part review on the application of bedside ultrasonography in the ICU. In this part, the following procedures will be covered: (1) echocardiography and cardiovascular diagnostics (second part); (2) the use of bedside ultrasound to facilitate central-line placement and to aid in the care of patients with pleural effusions and intra-abdominal fluid collections; (3) the role of hand-carried ultrasound in the ICU; and (4) the performance of bedside ultrasound by the intensivist. The safety and utility of bedside ultrasonography performed by adequately trained intensivists has now been well demonstrated. This technology, as a powerful adjunct to the physical examination, will become an indispensable tool in the management of critically ill patients.

Abstract
PURPOSE To determine retrospectively the accuracy of screening ultrasonography (US) in patients with hypotension (systolic blood pressure <or= 90 mm Hg) after blunt abdominal trauma. MATERIALS AND METHODS The investigational review board approved the study and waived informed consent. The study group consisted of 128 hypotensive patients with blunt abdominal trauma who underwent screening US over a 9-year period. Abdomens were scanned for free fluid and for parenchymal heterogeneity in visceral organs; scans that depicted these were considered positive. Prospective reports were used to calculate diagnostic performance. Patients were retrospectively given a fluid score according to the number of fluid pockets visualized (0, 1, or > or =2) (consensus by three readers) and were assigned to a low- or high-risk group according to the presence of hematuria and/or axial fracture on radiographs. Screening US results were compared with findings with the best available reference standard (computed tomography [CT]), repeat US, other diagnostic test, laparotomy, autopsy, clinical course). Data were compared by using chi(2) or Fisher exact test, depending on expected frequencies, with Bonferroni correction for multiple comparisons. Continuous variables were compared by using unpaired Student t test or Mann-Whitney U test, depending on data distribution. RESULTS The study included 77 male and 51 female patients (mean age, 42 years). Sensitivity was 85% (44 of 52) for detection of any injuries, 97% (30 of 31) for surgical injuries (ie, injuries requiring surgery), and 100% (10 of 10) for fatal injuries. Specificity was 96% (73 of 76), 82% (80 of 97), and 69% (81 of 118), and accuracy was 91% (117 of 128), 86% (110 of 128), and 71% (91 of 128), for respective injury categories. One nonfatal surgical injury was missed in a high-risk patient. For each injury category, frequency of injury in patients with a fluid score of 2 or more was nine times that in patients with a score of 0 (P < .001 for all comparisons). Frequency of false-negative US findings in high-risk patients was eight times that in low-risk patients (P < .01). CONCLUSION In patients who are hypotensive after blunt abdominal trauma and not hemodynamically stable enough to undergo diagnostic CT, negative US findings virtually exclude surgical injury, while positive US findings indicate surgical injury in 64% of cases.

Abstract
STUDY OBJECTIVE To determine if emergency center ultrasound (ECUS) can be of value to emergency physicians in the evaluation of possible ascites and accompanying decisions to perform emergent paracentesis. METHODS During a 7-month period, patients suspected of having ascites and potentially requiring paracentesis were prospectively entered into a randomized study in an urban public hospital emergency center (>140 000 annual visits). Patients were randomized to receive paracentesis using the traditional or the bedside ECUS-assisted technique. Indications for paracentesis included known liver disease and obvious ascites as well as suspected ascites or suspected subacute bacterial peritonitis. Participating physicians had received a minimum of 1 hour of formal didactic ultrasound training that included gallbladder, renal, vascular, and bladder studies as well as the focused abdominal sonography for trauma examination for trauma and the detection of ascites. A portable Terason 2000 laptop ultrasound machine with a 5-MHz probe was used to scan the patients. Data collected included the patients' characteristics, estimation of ascitic fluid volume, number of attempts made to obtain fluid, speed of paracentesis, and the operator's overall evaluation of the ECUS-assisted technique, if used. RESULTS Of 100 enrolled patients, 56 received the ECUS-assisted technique. Of 42 patients with ascites, 40 (95%) were successfully aspirated and 14 (25%) did not receive paracentesis because no ascites or insignificant amount of ascites was visualized. One patient was noted to have a large cystic mass in the left lower quadrant and another patient had a ventral hernia. Of the 44 patients randomized to the traditional technique, 27 (61%) were successfully aspirated. In 17 (39%) of these patients, fluid could not be obtained using traditional methods. Of these 17 failed attempts by traditional methods, 15 patients received ECUS in a "break" from the study protocol. Ascitic fluid was obtained in 13 of these 15 patients; of the 2 remaining patients, 1 did not have enough fluid to be sampled and the other had no fluid visualized. CONCLUSION Ninety-five percent (P=.0003) of the patients who were randomized in the ECUS group and in whom a needle paracentesis was performed had ascitic fluid successfully obtained, as compared with the traditional method group.

Abstract
This study was performed to find out whether ultrasound is an important adjunct to clinical and laboratory profile in diagnosing dengue fever or dengue haemorrhagic fever and to further determine whether ultrasound is useful in predicting the severity of the disease. Ultrasound was performed on 128 patients (2-9 years) with clinical suspicion of dengue fever. Serological tests were performed to confirm the diagnosis. 40 patients were serologically negative for dengue fever and later excluded from the study. Of the remaining 88 serologically positive cases, 32 patients underwent ultrasound on second to third day, repeated on fifth to seventh day of fever and in 56 patients ultrasound was done only on fifth to seventh day of fever. Of the 32 patients who underwent the study on second to third day of fever, all showed gall bladder wall thickening and pericholecystic fluid, 21% had hepatomegaly, 6.25% had splenomegaly and right minimal pleural effusion. Follow-up ultrasound on fifth to seventh day revealed ascites in 53% left pleural effusion in 22% and pericardial effusion in 28%. Of the 56 patients who underwent the study on fifth to seventh day of fever for the first time all had gall bladder wall thickening, 21% had hepatomegaly, 7% had splenomegaly, 96% had ascites, 87.5% had right pleural effusion, 66% had left pleural effusion and 28.5% had pericardial fluid. To conclude, in an epidemic of dengue, ultrasound features of thickened gall bladder wall, pleural effusion and ascites should strongly favour the diagnosis of dengue fever.

Abstract
INTRODUCTION The main role of the radiologist in the management of patients with suspicion of small bowel obstruction is to help triage patients into those that need immediate surgical intervention from those that require medical therapy or delayed surgery. Ultrasound examination is usually considered not helpful in bowel obstruction because of air in the intestinal lumen that interferes the evaluation of the intestinal loops, however recently some Authors attested the increasing important role of sonography in the acute abdominal disease. Aim of our report is to demonstrate the value of free fluid detected by US in differentiating between low and high-grade small bowel obstruction. MATERIALS AND METHODS The study is based on 742 consecutive patients who presented symptoms of the acute abdomen; all patients had undergone initial serial abdominal plain film and US examinations prior to any medical intervention. We reviewed the imaging findings of 150 cases in whom small bowel obstruction was clinically suspected and confirmed at surgery. We consider the following radiographic and US findings: dilatation of small bowel loops; bowel wall thickness; presence of air-fluid levels; thickness of valvulae conniventes; evidence of peristalsis; presence and echogenicity of extraluminal fluid. We looked at the value of extraluminal peritoneal fluid at US examination in differentiating low and high-grade small bowel obstruction based on the surgical outcome. RESULTS In 46 patients altered peristaltic activity, thin bowel walls, fluid filled loops with hyperechoic spots in the bowel segment proximal to obstruction were noted at US, whereas radiographic features were: moderate dilatation of small bowel loops, with thin bowel wall and evidence of numerous and subtle valvulae conniventes; presence of air-fluid levels was also noted. In 70 other patients, US examination revealed all the findings described in the precedent cases and also the presence of free extraluminal fluid; abdominal plain film showed an increased dilatation of small bowel loops with moderate thickened wall and air-fluid levels. In 34 other patients US examination revealed the presence of thick-walled loops, hypoperistalsis and a larger amount of free extraluminal fluid. Radiographic findings in these patients were: horizontal featured and markedly dilated small bowel loops presenting parietal thickness, presence of intraluminal fluid stasis and evidence of thickened, sparse and incomplete valvulae conniventes. At surgery etiology of small bowel obstructions was various, but most of cases related to adhesions (70 cases). The presence of extraluminal fluid were confirmed at surgery in 104 patients. CONCLUSIONS Our experience using sonography in suspicion of SBO (small bowel obstruction) suggests the usefulness of this imaging modality to differentiate a functional or obstructive ileus, demonstrating the evidence of intestinal peristalsis. Furthermore, the presence of a large amount of fluid between dilated small bowel loops suggests worsening mechanical small bowel obstruction, that requires not a medical therapy but immediate surgery.

Abstract
OBJECTIVE To determine the volume of pelvic fluid and febrile morbidity after hysterectomy in which the peritoneum was or was not closed. DESIGN Prospective single-center study. PARTICIPANTS Fifty-four women undergoing abdominal hysterectomy were enrolled in the study. Patients were randomized into two groups according to peritoneal closure: group I (n = 28) in which the peritoneum was closed, and group II (n = 26) in which the peritoneum was left open. All participants had early postoperative transvaginal ultrasound. OUTCOME MEASURES Volume of pelvic fluid accumulated after hysterectomy, total leukocytic count before and after hysterectomy, body temperature over the first 24 h, and wound healing. RESULTS There was a statistically significant difference between both groups regarding the volume of pelvic fluid collection, the duration of the operation and number of ampoules needed (p < 0.05). There was no statistically significant difference regarding body temperature, TLC, and wound complications. CONCLUSION Peritoneal non-closure does not increase short-term morbidity, however it does cause an increase in peritoneal pelvic fluid. The impact of this on long-term sequelae as adhesions should be investigated.

Abstract
OBJECTIVES To assess whether 10 focused abdominal sonography for trauma (FAST) examinations could be used as a minimum standard for training, as suggested previously. METHODS This was a retrospective review of patients with abdominal trauma who underwent resident-performed FAST examinations before surgical or Department of Radiology evaluation. RESULTS Six hundred ninety-eight patients were examined by resident-performed FAST followed by reference standard evaluations. Four hundred twelve patients were evaluated by residents who previously performed 10 FAST examinations; 154 were evaluated by 29 residents performing their 11th through 30th examinations; and 258 were evaluated by 10 residents performing their 31st and subsequent examinations. The results of resident-performed FAST for intraperitoneal free fluid were as follows: 11 to 20 examinations--sensitivity, 73.9% (95% confidence interval, 51.3%-88.9%); specificity, 98.8% (92.5%-99.9%); true-positive findings, 17; true-negative, 81; false-positive, 1; false-negative, 6; total patients, 105; 21 to 30 examinations--sensitivity, 100% (73.2%-100%); specificity, 97.1% (83.3%-99.9%); true-positive, 14; true-negative, 34; false-positive, 1; false-negative, 0; total patients, 49; 31 and more examinations--sensitivity, 94.8% (88.6%-97.9%); specificity, 98.6% (94.5%-99.8%); true-positive, 110; true-negative, 140; false-positive, 2; false-negative, 6; total patients, 258. CONCLUSIONS The suggestion that 10 examinations could be used as a minimum standard for training in FAST examinations was not validated.

Abstract
Ascites is a not infrequent finding on CT. Causes of ascites include congestive heart failure, hypoalbuminemia, cirrhosis, inflammation, and neoplasm. In most cases the attenuation of ascites is that of clear fluid, measuring around 0 HU. Rarely, however, a considerably higher density of ascites is seen. This finding may be a challenge for the radiologist, particularly since some of the conditions associated with it are of major clinical importance requiring prompt intervention.

Abstract
Two patients who presented to the Emergency Department (ED) in shock with severe pelvic fractures were evaluated for intra-abdominal injury with a focused assessment with sonography in trauma (FAST) examination. Free intraperitoneal fluid was identified in the hepato-renal recess of both patients. At laparotomy both patients were found to have extensive uroperitoneum resulting from intraperitoneal bladder rupture and no other intra-abdominal injuries. The source of shock in both cases was ultimately determined to be arterial hemorrhage from pelvic vessels. The utility of FAST examinations in the setting of major pelvic injury is relatively unstudied. Coincident injuries make the evaluation for source of hemorrhage in this subset of patients challenging. This is a report of sonographic intraperitoneal fluid in the setting of major pelvic injury and hemodynamic instability found to be uroperitoneum and not hemoperitoneum.

Abstract
The multiple-view focused assessment with sonography for trauma (FAST) exam is an integral tool in the assessment of blunt abdominal trauma. A prospective observational study was performed to compute the average minimum volume of detectable intraperitoneal fluid with the pelvic views of the FAST exam. All adult patients from October 1999 to May 2001, who presented to the ED with blunt abdominal trauma and underwent a clinically indicated diagnostic peritoneal lavage (DPL), were candidates for admission to the pelvic ultrasound study. In the supine position, patients were administered lavage fluid in 100 cc increments until the examiner detected the fluid on ultrasound. An independent reviewer also examined the hard-copy ultrasound images for fluid detection. Patients were excluded if they had (1) a positive DPL for hemoperitoneum (defined as 10 cc of gross blood or >100,000 red blood cells/mL), (2) a positive initial ultrasound for free fluid, or (3) lacked sufficient hard-copy ultrasound images. The mean minimal volume of fluid needed for pelvic ultrasound detection by the examiner and reviewer was 157 and 129 cc (n = 7), respectively. The median quantity of fluid for ultrasound detection by both the examiner and reviewer was 100 cc. The pelvic views of the FAST exam identified a significantly smaller quantity of intraperitoneal fluid than previous studies of the right upper quadrant single-view exam.
