RATIONALE: Abdominal apoplexy is a rare and fatal emergency event, which is coined as a comparison to the cerebrovascular apoplexy. The exact mechanism of abdominal apoplexy was unclear, but arteriosclerosis, hypertension, abdominal aneurysm, and other predisposing angiopathy were considered to be the main reasons of abdominal apoplexy. The development of the imaging technology gave us more opportunities to confirm the diagnosis of abdominal apoplexy. However, the diagnosis and identification of the bleeding sites still continued to be a challenge. PATIENT CONCERNS: A 55-year-old man presented to the emergency department with chief complains of sudden severe abdominal pain. DIAGNOSIS: The patient was diagnosed as abdominal apoplexy with 2 synchronous bleeding sites. INTERVENTIONS: Angiography confirmed diagnosis of abdominal apoplexy and revealed 2 synchronous bleeding sites in gastroduodenal artery (GDA) and inferior pancreaticoduodenal artery (IPDA). Transcatheter embolization was performed immediately. OUTCOMES: The patient recovered and was discharged very soon. Two months later, the patient totally recovered and the hematoma disappeared in the CT imaging. LESSONS: The reported case is rare, given the very low incidence of abdominal apoplexy with 2 synchronous bleeding sites in GDA and IPDA. The awareness of abdominal apoplexy was still the key point in the management of this disease. Quick diagnosis by the imaging and immediate embolization were very important for the treatment.

Inflammatory bowel diseases
BACKGROUND: The expression of elafin in inflammatory bowel disease (IBD) is controversial. Here, we detected the expression of elafin in the peripheral blood and colonic mucosa of patient with IBD and then explored its role and value in assessing the activity and severity of IBD. MATERIALS AND METHODS: Sixty-eight patients with IBD were selected as an experimental group. The control group included 38 healthy individuals. The expression of elafin mRNA in peripheral blood leukocytes and in serum was detected by qRT-PCR and enzyme-linked immunosorbent assay, respectively. The inflamed and noninflamed tissues were collected by colonoscopy. The expression of elafin in the intestinal mucosa was determined by immunohistochemistry staining and qRT-PCR. The expression of elafin between groups and among each stage of IBD was compared. The correlations of elafin expression with erythrocyte sedimentation rate and C-reactive protein were determined by Spearman's correlation analysis and with clinical disease activity indices (Best Crohn's Disease Activity Index and modified Mayo scores) by Pearson's correlation analysis. RESULTS: Elafin mRNA levels decreased significantly in active ulcerative colitis (UC) but increased in remission UC. However, in Crohn's disease (CD), we did not detect the aforementioned significant differences. Although serum IL-8 levels increased, serum elafin concentrations decreased both in UC and in CD, but the differences among stages were not significant. The expression of elafin in the inflamed colonic mucosa in both CD and UC was lower than that in the normal mucosa in controls and lower than that in the noninflamed mucosa in IBD. Moreover, the relative expression of elafin mRNA in peripheral blood leukocytes in UC was negatively correlated with erythrocyte sedimentation rate, C-reactive protein, and modified Mayo scores, and in CD, it was negatively correlated with Best Crohn's Disease Activity Index scores. CONCLUSIONS: Elafin decreased in active patients with IBD and was negatively correlated with disease activity, suggesting that elafin may play a protective role and could be used as an index to evaluate disease activity in IBD.

Diffusion-weighted imaging (DWI) is an increasingly utilized sequence in the assessment of abdominal and pelvic lesions. Benign lesions containing hemorrhagic products, with conglomerates of tightly packed blood cells or fibers, can have restricted water diffusion on DWI and apparent diffusion coefficient maps. Such lesions can have restricted diffusion erroneously attributed to malignancy. This review illustrates benign hemorrhagic lesions displaying restricted diffusion, with histopathologic correlation in relevant cases.

Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine
OBJECTIVES: The traditional activation ratio divides contracted muscle thickness by resting muscle thickness while an abdominal draw-in maneuver is performed during hook lying. Ultrasound imaging during function, such as standing or gait, or peak knee flexion in a single-leg squat allows for further visualization of muscle activity. The goal of this study was to examine activation ratio calculations for transverse abdominis function in supine versus loaded conditions to determine the most informative normalization strategy for muscle activity based on thickness values. METHODS: Transverse abdominis thickness was measured via ultrasound in 35 healthy participants under 4 different conditions. Comparisons were made between the traditional activation ratio tabletop, standing activation ratio (standing abdominal draw-in maneuver thickness/quiet standing thickness), and functional activation ratio (single-leg squat thickness/quiet standing thickness). Additionally, a cued activation ratio (single-leg squat with cued abdominal draw-in maneuver thickness/single-leg squat thickness) during the single-leg squat was obtained. Activation ratios of greater than 1.0 indicated that participants could activate the muscle during activity, and values were compared by analysis of variance. RESULTS: The participants included 23 women and 12 men with a mean age ± SD of 21.3 ± 2.7 years, mass of 66.1 ± 14.4 kg, and height of 168.5 ± 10.1 cm. Activation ratios exceeded 1.0 in 94.3% for the traditional activation ratio, 85.7% for the standing activation ratio, 82.9% for the cued activation ratio, and 82.9% for the functional activation ratio. With groups defined as tabletop activated or not, the standing, cued, and functional activation ratios were all significantly different (all P < .05). CONCLUSIONS: Normalizing muscle thickness to the corresponding functional position quiet value provides a useful functional activation ratio and may help clinicians better understand the transverse abdominis role during complex functional tasks. Assessment techniques using various formulas for activation ratios reveal that the muscle functions differently during weight bearing compared to traditional measures.

The diagnosis of gallstone ileus relies on a radiological approach, and herein we discuss the benefits and drawbacks of the use of different modalities of radiological imaging: plain abdominal films, computed tomography, magnetic resonance imaging, and ultrasound scanning. Based on our case experience and review of the literature, the authors conclude that although an effective first-line tool, plain abdominal ...

Gastrointestinal endoscopy
BACKGROUND & AIMS: Assessment of prognostic factors in Crohn's disease (CD) patients is of pivotal importance for early intervention and "treat-to-target" strategies. Confocal Laser Endomicroscopy (CLE) enables on demand in vivo characterization of mucosal inflammatory and architectural changes during endoscopy. We prospectively assessed the value of CLE for prediction of clinical outcome parameters in CD. METHODS: Consecutive patients with CD undergoing colonoscopy were included in a multicentre study. Confocal imaging focused on two highly reproducible histological hallmarks of active colonic inflammation: focal cryptitis and crypt architectural abnormality. It was evaluated whether CLE, CD endoscopic index of severity (CDEIS), serum C-reactive protein (CRP) and CD activity index (CDAI) were associated with the risk of medical treatment escalation, transmural adverse events, and CD-related hospitalization or surgery during a 4-year follow-up. RESULTS: Among forty-nine patients (53% men, median age 39 years), baseline CRP was ≥5 mg/L in 47%, CDEIS≥3 in 75%, and CDAI >150 in 51%. Focal cryptitis and crypt architectural abnormality were observed in 63% ("CLE+ group"). CLE+ patients showed an increased incidence of medical treatment escalation (P < 0.001, RR=3.27) and transmural lesions (P=0.025, RR=1.70), whereas patients showing CRP ≥5 mg/L with CD-related hospitalization and surgery (P=0.020, RR=2.71) at 1-year follow-up. No further association with prognostic clinical outcomes was found over the 1-year follow-up as well as for CDEIS and CDAI at any time. CONCLUSIONS: CLE reveals CD-related features of mucosal inflammation and allows for early prediction of relevant clinical outcomes. Further studies should now address whether this promising prognostic tool could refine the timing of treatment strategies in patients with CD.
