Abstract
Aim
This study aimed to compare open abdominal management (OAM) between visible negative pressure wound therapy (NPWT) and commercial NPWT to determine whether NPWT can detect intestinal ischemia in its early stages without causing complications or worsening prognosis, and to determine whether the actual visualization results in early detection.
Methods
Patients were divided into two groups: those who underwent OAM with visible NPWT (A: 32 patients) and those who underwent OAM with commercial NPWT (B: 12 patients). We compared background factors, disease severity, vital signs, blood test values, and 28‐day outcomes between the two groups. We also checked the records to determine how many visualized cases were detected early and operated on. We then examined the weaknesses of this method.
Results
No differences were observed in the background factors or disease severity between the two groups. The duration of the open abdomen and intensive care unit stay were significantly shorter for group A than for group B. The groups showed no significant differences in lactate levels, 28‐day outcomes, complications during OAM, or other factors. After a review of the medical records, ischemic progression was detected early, and surgery could be performed in seven cases in the visible NPWT group. The progression of ischemia was confirmed at the time of the second‐look operation in two cases in the ascending colon.
Conclusion
The visualization device allowed us to gain insights into the intra‐abdominal cavity and determine the appropriate time for closing the abdomen without worsening the prognosis.
