OBJECTIVETo explore the diagnostic value of 3D-indirectmagnetic resonance (MR) arthrography in detecting meniscustears of the knees.

METHODSForm January 2013 to January 2014, routine plain MR of the knees followed by the 3D-indirect MR arthrography was performed in 42 patients with suspected meniscal tears clinically. There were 31 males and 11 females, with an average age of 38.4 years old (ranged, 21 to 67 years old). The duration of the course ranged from 2 h to 15 d. The clinical symptom was knee pain. All the patients got subsequently arthroscopic examination or operation. The sensitivity and specificity of routine plain MR and 3D-indirect MR arthrography were compared based on the results of arthroscopic examination or operation.

RESULTSThe signal intensity in the area of meniscal tears on image of 3D-indirect MR arthrography was obviously higher than that of routine plain MR. The sensitivity of 3D-indirect MR arthrography was 85.79% (87/102), while the routine plain MR was 52.94% (54/102), and the specificity improved from 67.78%(61/90) to 86.67%(78/90). The difference was statistically significant (χ2 = 25.90, P < 0.01; χ2 = 9.13, P < 0.01).

CONCLUSIONIn comparison with the routine plain MR findings, 3D-indirect MR arthrography demonstrates meniscus tears of the knee with the better sensitivity and specificity.

OBJECTIVETo compare the clinical safety and efficacy of laparoscopic versus open colorectal resection in octogenarians. Methods Studies comparing laparoscopic colorectal resection with open colorectal resection in octogenarians were identified from the Medline, Embase, Ovid, and Cochrane databases from 1990 to 2012. The methodological quality of the selected studies was assessed to determine studies suitable for inclusion. Meta-analysis was performed by fixed or random effects model.

RESULTSFive observational studies with a total of 685 patients (330 laparoscopic colorectal resections and 355 open colorectal resections) were identified. Laparoscopic colorectal resection was associated with a prolonged operative time (WMD=27.89, P<0.01) and a lower rate of overall complications (OR=0.58, P<0.01), wound infection (OR=0.50, P<0.05), cardiovascular complication(OR=0.53, P<0.05), quicker bowel function return (WMD=-0.83, P<0.01), and shorter length of hospital stay (WMD=-3.60, P<0.05). No differences were found with regard to anastomotic leak (OR=1.13, P>0.05), prolonged ileus (OR=0.71, P>0.05), respiratory complication (OR=0.59, P>0.05),mortality (OR=0.67, P>0.05), and reoperation (OR=0.85, P>0.05).

CONCLUSIONLaparoscopic colorectal resection is as safe as open colorectal resection, and is more favorable in terms of length of hospital stay and bowel function return in octogenarians.
