Gastric emptying before and after cholecystectomy in patients with cholecystolithiasis.

Background/aims: The objective of the present study was to measure gastric emptying time of solids and semisolids in dyspeptic individuals with cholecystolithiasis before and 6 months after cholecystectomy in order to determine whether cholecystectomy interferes with gastric emptying.

Methodology: A prospective, self-pairing study was conducted on 29 patients selected according to appropriate inclusion and exclusion criteria. Gastric emptying time of solids and semisolids was determined before and six months after laparoscopic cholecystectomy by the 13C-octanoic acid and 13C-acetate breath tests, respectively.

Sensorineural hearing loss in chronic suppurative otitis media with and without cholesteatoma.

Unlabelled: Sensorineural hearing loss (SNHL) related to chronic suppurative otitis media (CSOM) was studied to clarify the involvement of cholesteatomas in this context.

Aim: to evaluate SNHL related to CSOM and its association with cholesteatomas, disease duration and patients ages.

Methods: Retrospective analysis of 115 patients with CSOM with and without cholesteatoma submitted to surgical treatment.
