[Vacuum pack technique--a good method for temporal abdominal closure].

UNLABELLED: Abdominal compartment syndrome(ACS) is a clinical entity characterised by increased intraabdominal pressure leading to multiple organ failure, fatal if left untreated. The treatment of abdominal compartment syndrome is surgical decompression with a temporary abdominal wall substitute. To avoid the development of abdominal compartment syndrome, temporary abdominal closure (TAC) should be considered after celiotomy for trauma. A new method for TAC was introduced at Ullevaal University Hospital in 2002, the "vac pac". METHOD: The "vac pac" technique is described and the patients treated with "vac pac" during the first year after introduction are presented. RESULTS: Five patients were treated using the "vac pac". One patient had acute pancreatitis and developed abdominal compartment syndrome. The other patients were severely injured and the indication for TAC was abdominal compartment syndrome in one patient, intestinal oedema in another, and damage control surgery with packing in two patients. Delayed primary closure was achieved within five days in all our patients. There were no fatalities and no complications related to the use of "vac pac" were registered. CONCLUSION: The "vac pac" technique seems to be a good method for TAC.

MRI of slow flow in artificial duct in swine.

Our aim was to evaluate whether it is possible to visualize slow flow within a small catheter placed inside a living animal. We used a flow-sensitive, single-shot turbo spin-echo (SS-TSE) MRI sequence, developed in house, based on diffusion-weighted (DW) techniques. Four anesthetized pigs were used as models. A plastic catheter was surgically placed within the common bile duct (CBD). To mimic flow, the catheter was filled with Ringer's acetate and connected to a pump. b factors (s/m(2)) of 0, 6, and 12, with flow velocities raging from 0 to 1.32 cm/s, were used. A total of 375 images were obtained and examined. After correction for bowel movement artifacts, all images displayed the catheter on zero flow. With a flow of 0.66 cm/s or higher, no images displayed the catheter with a b factor of 6 or 12. On the slower flow velocities, it was variable whether the catheter was visible or not, but at b=6 and flow 0.17 cm/s all catheters were viewable. This method made it possible to perform a semiquantitative evaluation of flow velocities in vivo, dividing flow into three groups.
