Tapering pressure of wall vacuum-assisted closure for the treatment of patients with pancreatic fistula in traumatic pancreatic injury: Report of two cases

摘要

Introduction Traumatic injury to the pancreas is rare and difficult to diagnose, requiring immediate operative management. It also has high mortality and morbidity rates. Postoperative pancreatic fistula is one of the complications that is considered a nightmare for digestive surgeons. The prevalence of POPF is estimated at 13%–41%, with 28% of mortality rate and the most common cause of death is retroperitoneal sepsis and hemorrhage. It requires complex treatment and a long duration of hospitalization of patients with a large cost burden. Presentation of case Here we report 2 cases of POPF after pancreatic injury in abdominal trauma. The patients underwent emergency laparotomy. In the hospital ward, the patients developed wound dehiscence and a clear viscous pancreatic juice came out from the wound with high output. The installation of wall VAC using wall suction with pressure adjustments according to the number of products per day was performed. The patients showed good outcomes, the pancreatic juice output decreased and diminished, and the wound also narrowed and closed. Discussion VAC using wall suction is a device that applies the technique of NPWT and an emerging procedure used to treat patients with complex wounds. NPWT can reduce pooling of fluid, while reducing shear stress and tissue hypoxia at the wound edges, and stimulating the release of vascular endothelial growth factor in wound milieu. Conclusions Tapering pressure of VAC using wall suction for treatment of pancreatic fistula in post laparotomy pancreatic injury patients is a simple and easy procedure with good outcomes.
