SIX MONTH FOLLOW-UP OF PATIENTS SUBMITTED TO TOTAL KNEE ARTHROPLASTY WITH AND WITHOUT PLACEMENT OF SUCTION DRAINAGE DEVICES.

Objective: The aim of this study was to prospectively evaluate the evolution and postoperative complication patterns relating to the use of suction drains, in comparison with not using these devices in total knee arthroplasty (TKA) procedures.

Methods: Forty-two patients at a knee surgery referral clinic were included. Fifteen patients did not receive suction drainage postoperatively and 27 received suction drainage.

Displaced radial neck fractures in children: association of the Métaizeau and Böhler surgical techniques.

Objectives: To evaluate the results of surgical treatment of displaced radial neck fractures in children using an association of the Böhler reduction technique and the intramedullary fixation described by Métaizeau.

Methods: Of the 68 children diagnosed with radial neck fractures, 28 (41.1%) were classified as O'Brien type III and surgically treated by the association of Böhler and Métaizeau techniques between December 1998 and April 2007.

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.
