@entity516 ( @entity516 ) is a safe and effective procedure in the treatment of large incisional @entity547 (size > 10 cm in width or length) with loss of domain (LIHLD). There is no consensus in the literature on the amount of gas that must be insufflated in a @entity516 program or even how long it should be maintained. We describe a technique for calculating the @entity547 ( @entity547 ) and @entity6675 ( @entity6675 ) based on abdominal computerized tomography (ACT) scanning that eliminates the need for subjective criteria for inclusion in a @entity516 program and shows the amount of gas that must be insufflated into the abdominal cavity in the @entity516 program. Our technique is indicated for all @entity1 with large or recurrent incisional @entity547 evaluated by a senior surgeon with suspected LIHLD. We reviewed our experience from 2001 to 2008 of 23 consecutive @entity547 surgical procedures of LIHLD undergoing preoperative evaluation with CT scanning and @entity516 . An ACT was required in all @entity1 with suspected LIHLD in order to determine @entity547 and @entity6675 . The @entity516 was performed only if the volume ratio @entity547 / @entity6675 (VR = @entity547 / @entity6675 ) was >or=25% (VR >or= 25%). We have performed this procedure on 23 @entity1 , with a mean age of 55.6 years (range 31-83). There were 16 @entity1 and 7 @entity1 with an average age of 55.6 years (range 31-83), and a mean BMI of 38.5 kg/m(2) (range 23-55.2). Almost all @entity1 (21 of 23 @entity1 -91.30%) were overweight; 43.5% (10 @entity1 ) were severely @entity28 ( @entity28 class III). The mean calculated volumes for @entity6675 and @entity547 were 9,410 ml (range 6,060-19,230 ml) and 4,500 ml (range 1,850-6,600 ml), respectively. The @entity516 is performed by permanent catheter placed in a minor surgical procedure. The total amount of @entity515 insufflated ranged from 2,000 to 7,000 ml (mean 4,000 ml). @entity1 required a mean of 10 @entity516 sessions (range 4-18) to achieve the desired volume of gas (that is the same volume that was calculated for the @entity547 ). Since @entity516 sessions were performed once a day, 4-18 days were needed for preoperative preparation with @entity516 . The mean VR was 36% (ranged from 26 to 73%). We conclude that ACT provides objective data for volume calculation of both @entity4036 and also for estimation of the volume of gas that should be insufflated into the abdominal cavity in @entity516 .
