Comparative StudyInvestigation of colonic and whole-gut transit with wireless motility capsule and radiopaque markers in constipation.
Colonic transit time (CTT) traditionally is assessed with radiopaque markers (ROMs), which requires radiation and is hindered by lack of standardization and compliance. We assessed regional and CTT with the SmartPill (SmartPill Corporation, Buffalo, NY), a new wireless pH and pressure recording capsule, in constipated and healthy subjects and compared this with ROM. ⋯ The SmartPill is a novel ambulatory technique of assessing regional (gastric, small bowel, colonic) and WGTT without radiation. It reveals hitherto unrecognized gender differences and upper-gut dysfunction in constipation. It correlates well with ROM and offers a standardized method of discriminating normal from slow colonic transit.

Comparative StudyA comparison of hepatic mucinous cystic neoplasms with biliary intraductal papillary neoplasms.
There is controversy regarding the term biliary intraductal papillary neoplasms (IPN-B) and their pathology, which frequently are confused with hepatic mucinous cystic neoplasms (MCN). We aimed to summarize the clinicopathologic features of IPN-B and differentiate them from MCN. ⋯ Intrahepatic IPN-B represents a distinct clinicopathologic entity that differs clinically, histologically, and radiologically from MCN. Curative resection has a favorable prognosis for patients with IPN-B, but further studies of its subtype are required.
