Components separation technique is feasible for assisting delayed primary fascial closure of open abdomen

Background and aims: The goal after open abdomen treatment is to reach primary fascial closure. Modern negative pressure wound therapy systems are sometimes inefficient for this purpose. This retrospective chart analysis describes the use of the ‘components separation’ method in facilitating primary fascial closure after open abdomen. Material and methods: A total of 16 consecutive critically ill surgical patients treated with components separation during open abdomen management were analyzed. No patients were excluded. Results: Primary fascial closure was achieved in 75% (12/16). Components separation was performed during ongoing open abdomen treatment in 7 patients and at the time of delayed primary fascial closure in 9 patients. Of the former, 3/7 (43%) patients reached primary fascial closure, whereas all 9 patients in the latter group had successful fascial closure without major complications (p = 0.019). Conclusion: Components separation is a useful method in contributing to successful primary fascial closure in patients treated for open abdomen. Best results were obtained when components separation was performed simultaneously with primary fascial closure at the end of the open abdomen treatment.
