Incidental Carcinoma after Cholecystectomy for Benign Disease of the Gallbladder: A Meta-Analysis.

This study aimed to determine the incidence and the prognosis of incidental carcinoma of the gallbladder (IGBC) after cholecystectomy through a meta-analysis. This meta-analysis included 51 studies and 436,636 patients with cholecystectomy. The incidence rate of IGBC after cholecystectomy was 0.

Comparison between Conventional Smear and Liquid-Based Preparation in Endoscopic Ultrasonography-Fine Needle Aspiration Cytology of Pancreatic Lesions.

The present study aimed to compare the diagnostic accuracy between conventional smear (CS) and liquid-based preparation (LBP) in endoscopic ultrasonography-fine needle aspiration cytology (EUS-FNAC) of pancreatic lesions. Using 31 eligible studies, the diagnostic accuracy of cytologic examination in CS and LBP was evaluated through a conventional meta-analysis and diagnostic test accuracy review. Overall concordance rates were 82.

Comparison of the osteogenic potentials of autologous cultured osteoblasts and mesenchymal stem cells loaded onto allogeneic cancellous bone granules.

We compared the bone regeneration potentials of autologous cultured osteoblasts and of bone-marrow-derived autologous MSCs in combination with allogeneic cancellous bone granules in a rabbit radial defect model. Radial shaft defects over 15 mm were made in 26 New Zealand white rabbits. The animals underwent insertion of allogeneic cancellous bone granules containing autologous osteoblasts into right-side defects (the experimental group) and of allogeneic cancellous bone granules with autologous MSCs into left-side defects (the control group).
