In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
question:
Context: Acute pancreatitis is the most common adverse event of endoscopic retrograde cholangiopancreatography (ERCP). We aimed to evaluate the efficacy of intramuscular diclofenac sodium for prophylaxis of post-ERCP pancreatitis (PEP) in comparison to the rectal form.', 'One hundred and fifty consecutive patients who underwent ERCP were enrolled in this single-center, prospective, randomized controlled study. Patients were randomized into three groups. The first group received 75 mg of diclofenac sodium via intramuscular route and the second group received 100 mg of diclofenac sodium rectally 30-90 min before the procedure. The third group served as the control group. Patients were evaluated for post-ERCP pancreatitis with serum amylase levels and abdominal pain 24 h after the procedure.', 'The overall incidence of PEP was 6% (n = 9) and 2% (n = 1) in the intramuscular (IM) and rectal groups, respectively, and 14% in the control group (P = 0.014). Nineteen (12.7%) patients developed post-ERCP abdominal pain (8% in IM, 10% in rectal, and 20% in control group; P = 0.154). Twenty-five (16.6%) patients developed post-ERCP hyperamylasemia (10% in IM, 12% in rectal, and 24% in control group; P = 0.03).\Question: Does rectal or intramuscular diclofenac reduce the incidence of pancreatitis afterendoscopic retrograde cholangiopancreatography?
answer:
Prophylaxis with diclofenac given rectally or intramuscularly is an effective option for the management of post-ERCP pancreatitis.

question:
Context: Interobserver and intraobserver reliability study of improved method to evaluate radiographs of patients with scoliosis.', 'To determine the reliability of a computer-assisted measurement protocol for evaluating Cobb angle and King et al classification.', 'Evaluation of scoliosis radiographs is inherently unreliable because of technical and human judgmental errors. Objective, computer-assisted evaluation tools may improve reliability.', 'Posteroanterior preoperative radiographic images of 27 patients with adolescent idiopathic scoliosis were each displayed on a computer screen. They were marked 3 times in random sequence by each of 5 evaluators (observers) who marked 70 standardized points on the vertebrae and sacrum in each radiograph. A computer program (Spine 2002;27:2801-5) that identified curves, calculated Cobb angles, and generated the King et al classification automatically analyzed coordinates of these points. The interobserver and intraobserver variability of the Cobb angle and King et al classification evaluations were quantified and compared with values obtained by unassisted observers.', 'Average Cobb angle intraobserver standard deviation was 2.0 degrees for both the thoracic and lumbar curves (range 0.1 to 8.3 degrees for different curves). Interobserver reliability was 2.5 degrees for thoracic curves and 2.6 degrees for lumbar curves. Among the 5 observers, there was an inverse relationship between repeatability and time spent marking images, and no correlation with image quality or curve magnitude. Kappa values for the variability of the King et al classification averaged 0.85 (intraobserver).\Question: Do computer-assisted algorithms improve reliability of King classification and Cobb angle measurement of scoliosis?
answer:
Variability of Cobb measurements compares favorably with previously published series. The classification was more reliable than achieved by unassisted observers evaluating the same radiographs. The same principles may be applicable to other radiographic measurement and evaluation procedures.

question:
Context: The aim of this study was to evaluate the value and accuracy of multiplanar reconstruction (MPR) of three-dimensional (3D) transthoracic echocardiographic data sets in assessing mitral valve pathology in patients with surgical mitral valve prolapse (MVP).', 'Sixty-four patients with surgical MVP and preoperative two-dimensional (2D) and 3D transthoracic echocardiography were analyzed. The descriptions obtained by 3D MPR and 2D were compared in the context of the surgical findings.', 'Two-dimensional echocardiography correctly identified the prolapsing leaflets in 32 of 64 patients and 3D MPR in 46 of 64 patients (P=.016). Among the 27 patients with complex pathology (ie, more than isolated middle scallop of the posterior leaflet prolapse), 3D MPR identified 20 correctly, as opposed to 6 with 2D imaging (P<.001).\Question: Does multiplanar reconstruction of three-dimensional transthoracic echocardiography improve the presurgical assessment of mitral prolapse?
answer:
Interpretation of 3D transthoracic echocardiographic images with MPR improved the accuracy of the description of the MVP compared with 2D interpretation. This added value of 3D MPR was most important in extensive and/or commissural prolapse.
