Strict closed-system drainage for treating XXXX .

@entity1 @entity260 @entity6087 @entity6675 @entity5099 @entity1585 @entity6659
A comparative study chiefly of the recurrence rate of @entity6087 after two treatment modalities was conducted. @entity1 were divided into a burr hole strict closed-system drainage group ( @entity5099 group; n=56) and a burr hole closed-system drainage with irrigation group ( @entity6659 group; n=45). The burr hole strict closed-system drainage involved simply inserting a drainage tube into the @entity6675 as quickly as possible after minimally incising the haematoma capsule. The introduction of air into the @entity6675 was prevented, and irrigation was not performed. Symptoms in both @entity1585 disappeared soon after surgery, with no @entity260 . Haematoma recurred in one @entity1 (1.8%) of the @entity5099 group compared with 5 (11.1%) of the @entity6659 group. The rate of recurrence was significantly lower for the @entity5099 than for the @entity6659 group (p<0.05). In 4 of 5 recurrences in the @entity6659 group, the volume of residual intracapsular air was sufficient after initial surgery. These results suggested that postoperative residual intracapsular air is a factor contributing to recurrence. Burr hole strict closed-system drainage is a simple, less invasive procedure with which to treat @entity6087 and the outcome is excellent. Furthermore, prevention of intracapsular air intrusion during surgery might help prevent recurrence.
