Background:Endoscopic retrograde cholangiopancreatography (ERCP), followed by laparoscopic cholecystectomy (LC), remains the standard way of management for patients with cholecystocholedocholithiasis. Laparoendoscopic rendezvous (LERV), a combined procedure for removing the gallbladder laparoscopically and clearing the common bile duct (CBD) endoscopically at the same time, could be an attractive alternative. The aim of this study was to compare LERV with classic ERCP in patients with cholecystocholedocholithiasis.Methods:886 patients with cholecystocholedocholithiasis were treated either with the LERV technique (90 patients), or with the 2-stage approach, which includes preoperative ERCP followed by LC (796 patients). The primary endpoint was any difference in the success of CBD cannulation and clearance; secondary endpoints were the detection of differences in morbidity (especially post-ERCP pancreatitis [PEP]), and the feasibility of the two approaches.Results:Successful cannulation of the CBD was more frequent with conventional ERCP compared with the LERV technique (89.8% vs. 75.5%, P=0.0001). LERV appears to be as effective as conventional ERCP for complete CBD clearance (85.5% vs. 82.8%, P<0.1). None of the patients in the LERV group had an episode of clinical PEP, whereas in the conventional ERCP group there were 23 episodes of PEP and one death. The median amylase level was higher in patients undergoing conventional ERCP group compared to patients in LERV group.Conclusion:Classic ERCP has a higher rate of successful CBD cannulation and a similar rate of CBD clearance compared to LERV.

Our study evaluated the role of the T2–fluid-attenuated inversion recovery (FLAIR) mismatch sign in detecting isocitrate dehydrogenase (IDH) mutations based on a mixed sample of 24 patients with low- and high- grade gliomas. The association between the two was realized using univariate and multivariate logistic regression analysis. There was a substantial agreement between the two raters for the detection of the T2–FLAIR mismatch sign (Cohen’s kappa coefficient was 0.647). The T2–FLAIR mismatch sign when co-registered with the degree of tumor homogeneity were significant predictors of the IDH status (OR 29.642; 95% CI 1.73–509.15, p = 0.019). The probability of being IDH mutant in the presence of T2–FLAIR mismatch sign was as high as 92.9% (95% CI 63–99%). The sensitivity and specificity of T2–FLAIR mismatch sign in the detection of the IDH mutation was 88.9% and 86.7%, respectively. The T2–FLAIR mismatch sign may be an easy to use and helpful tool in recognizing IDH mutant patients, particularly if formal IDH testing is not available. We suggest that the adoption of a protocol based on imaging and histological data for optimal glioma characterization could be very helpful.

BackgroundThe incidence of adrenal injury after trauma is very rare. Bilateral adrenal injury, which may lead to acute adrenal insufficiency and death, whereas unilateral adrenal trauma is often asymptomatic and masked by injuries to other organs. However, when unilateral adrenal trauma is associated with multiple injuries including brain trauma, critical illness‑related corticosteroid insufficiency (CIRCI) may be present; despite the importance, criteria for the diagnosis are not well established.Case presentationWe report a 16-year-old multi-trauma, brain-injured patient with unilateral adrenal gland injury. An intraparenchymal catheter for intracranial pressure (ICP) monitoring was inserted and craniectomy was performed. Postoperatively, the patient was admitted in the Intensive Care Unit (ICU) under sedation. He presented severe circulatory shock (noradrenaline dose of 1.86 μg/kg/min). which was not reversed despite red blood cell transfusions (noradrenaline increased to 2 μg/kg/min, lactate 1.8-2.1 mmol/L, although Hct was stabilized to 34 g/dl). Empiric hydrocortisone (150 mg intravenously) was administered for suspected adrenal insufficiency, after a blood sample for cortisol levels was drawn. An abrupt improvement in hemodynamics was noted [noradrenaline dose was reduced by half (1 μg/ kg/min) in less than 1 hour, and almost became insignificant during the next 8 hours, while lactate normalized (0.9 mmol/L)]. Hydrocortizone administration was continued for nine days. Fluid balance was restored after the first day. Baseline cortisol levels were 11.45 μg/dl. ICP was steadily less than 20 mmHg. Adrenal hematoma dimensions had increased (4 x 2.7 cm), as seen in the abdominal CT scan performed 9 hours after admission. Twenty days later, a follow up CT scan revealed regression of the hematoma. His remaining ICU course was complicated by fever and sepsis and remained in the ICU for 41 days.ConclusionAlthough, data do not support the use of empiric steroids in trauma patients (with or without brain injury), this case demonstrates that adrenal insufficiency must be considered in the differential diagnosis when shock exists; adrenal gland injury, even unilateral, may play an additional factor. An urgent decision is needed, that can influence outcome.
