Dexon mesh splenorrhaphy for intraoperative splenic injuries

The preferred management option for intraoperative splenic injuries is organ repair and preservation rather than splenectomy given the important immunologic function of the spleen. Wrapping the injured spleen with a Dexon mesh has been shown to be an effective alternative to splenectomy for significant splenic bleeding. However, this technique uses a foreign body that carries a theoretical infectious risk particularly in cases in which the alimentary tract has been opened. This study was undertaken to evaluate whether Dexon mesh splenorrhaphy when used for intraoperative splenic injuries was associated with significant infectious complications. The clinical courses of 23 patients who had Dexon mesh splenorrhaphy performed at a university teaching hospital for intraoperative splenic injury from 1991 to 1999 were reviewed. Eleven patients (48%) had their gastrointestinal tract opened during the surgery. No patients developed an intra-abdominal abscess or required reoperation for bleeding. The most common postoperative complications were left lower lobe atelectasis (18 patients, 78%), postoperative fever (13 patients, 56%), and left pleural effusion (12 patients, 52%). Dexon mesh splenorrhaphy effectively controls splenic bleeding due to intraoperative injury without significant infectious complications.
