Randomized Controlled Trial Clinical Trial
Drainage after cholecystectomy. A prospective randomized clinical trial.
This prospective clinical study was done to assess the efficacy of postcholecystectomy drainage. A total of 173 cholecystectomized patients were randomized into two groups; group A (86 patients) without drainage and group B (87 patients) with drainage. Group B included two types of patients; B1 (52 patients) with suction drain and B2 (35 patients) with gravity drain. ⋯ There was no significant difference in the rate of wound infection or atelectasis in either group, although there was apparent increase of lung complications and subhepatic collections in Group B1. The average postoperative hospital stay was significantly increased in group B patients. Considering all the parameters of this study, it was found that drainage with gravity was attended with the least morbidity.

A classification system for ankle fractures was developed. The system was based on 2 general fracture divisions, namely uni-, bi-, and tri-malleolar ankle fractures, and the localisation of the fracture at the level of the fibula. The use of the system in 612 ankle fractures that were surgically treated at the Leuven University Hospital between 1978 and 1988 led to the following conclusions: 1. ⋯ The system was easy workable also for young residents and physiotherapists. 3. It was accessible to repetition, allowing for comparisons between different subjects. 4. Taking into account the type of fracture, the final result could be predicted.
