Strong correlations between the grade of fibrosis and cirrhosis, classified using the Ishak scoring system, and the uptake characteristics of Gd-EOB-DTPA with the relative enhancement (RE) of the liver parenchyma have been reported. To confirm the results of a retrospective analysis, patients undergoing liver surgery were prospectively examined with Gd-EOB-DTPA-enhanced liver 3 Tesla MRI to determine the degree of liver fibrosis. Correlations between the grade of fibrosis and cirrhosis, classified using the Ishak scoring system, and RE were investigated and compared with those derived from an initial retrospective study. After validating the cut-off values in the retrospective study (Ishak ≥ 1, RE-cut-off 0.90; Ishak ≥ 2, RE-cut-off 0.79; Ishak ≥ 4, RE-cut-off 0.60; and Ishak = 6, RE-cut-off 0.47), we showed that Gd-EOB-DTPA has a high sensitivity (≥86%) and a high positive predictive value (≥86%). These results support the use of Gd-EOB-DTPA-enhanced liver MRI as a non-invasive method for determining the degree of liver fibrosis and cirrhosis.
Surgical site infections (SSI) in open Hepatopancreatobiliary (HPB) surgery are common complications. They worsen patients’ outcomes and prolong hospital stays. Their economic significance in the German diagnosis related groups (DRG) system is mostly unknown. To investigate their economic importance, we evaluated all cases for SSIs as well as clinical and financial parameters undergoing surgery in our centre from 2015 and 2016. Subsequently, we carried out a cost‐revenue calculation by assessing our billing data and the cost matrix of the InEK (German Institute for the Payment System in Hospitals). A total of 13.5% of the patients developed a superficial, 9% a deep incisional, and 2.4% of the patients an organ space SSI. Compared with Patients without SSI, Patients with SSI had more comorbidities, were older, and their average length of stay was extended by 19 days (P < .001). The financial loss per SSI‐case was €‐7035.65 despite increased reimbursement, which resulted in a calculated total loss for the hospital of €‐802 064.62 in 2015 and 2016. Surgical site infections are common complications of open HPB surgery, which lead to a significant increase in the cost per case. Further prevention strategies need to be developed. Besides, an adjustment of revenues must be demanded.
Background: Risks for living-liver donors are lower in case of a left liver donation, however, due to lower graft volume, the risk for small-for-size situations in the recipients increases. This study aims to prevent small-for-size situations in recipients using an auxiliary two-staged partial resection liver transplantation (LTX) of living-donated left liver lobes. Case presentation: Two patients received a two-stage auxiliary LTX using living-donated left liver lobes after left lateral liver resection. The native extended right liver was removed in a second operation after sufficient hypertrophy of the left liver graft had occurred. Neither donor developed postoperative complications. In both recipients, the graft volume increased by an average of 105% (329 ml to 641 ml), from a graft-to-body-weight ratio of 0.54 to 1.08 within 11 days after LTX, so that the remnant native right liver could be removed. No recipient developed small-for-size syndrome; graft function and overall condition is good in both recipients after a follow-up time of 25 months. Conclusions: Auxiliary two-staged partial resection LTX using living-donor left lobes is technically feasible and can prevent small-for-size situation. This new technique can expand the potential living-donor pool and contributes to increase donor safety.
Background: After pediatric split liver transplantation, intra‐abdominal loss of domain due to large‐for‐size left lateral grafts is a frequent problem for fascial closure and potentially leads to reduced liver perfusion and abdominal compartment syndrome. Therefore, delayed fascial closure with the use of temporary silastic meshes and reoperation or alternative fascial bridging procedures are necessary.Methods: Between March 2019 and October 2021, biologic meshes were used for abdominal wall expansion in 6 cases of pediatric split liver transplantation. These cases were analyzed retrospectively.Results: One male and 5 female children with median age of 6 months (range: 0–57 months) and weight of 6 kg (range: 3.5–22 kg) received a large‐for‐size left lateral graft. Graft‐to‐recipient weight ratio (GRWR) was 4.8% (range: 1.5%–8.5%) in median. Biologic mesh implantation for abdominal wall expansion was done in median 7 days (range: 3–11 days) after transplantation when signs of abdominal compartment syndrome with portal vein thrombosis in 3 and of the liver artery in 1 case occurred. In 2 cases, bovine acellular collagen matrix and 4 cases ovine reinforced tissue matrix was used. Median follow‐up was 12.5 months (range: 4–28 months) and showed good liver perfusion by sonography and normal corporal development without signs of ventral hernia. One patient died because of fulminant graft rejection and emergency re‐transplantation 11 months after the initial transplantation.Conclusions: Biologic meshes can be used as safe method for abdominal wall expansion to achieve fascial closure in large‐for‐size liver transplant recipients. Usage for primary fascial closure can be considered in selected patients.
Development of subcutaneous abdominal wound healing impairment (SAWHI) can greatly affect patient care. Complications from SAWHI include delayed healing, increased risk of infection, and fascial dehiscence resulting in increased patient care and associated costs. Treatment options include conventional wound treatment or negative pressure wound therapy, both of which can be used in the out‐of‐hospital setting. However, limited published evidence on cost‐effectiveness exists. A conservative health economic model was created to assess the cost–benefit of negative pressure wound therapy in the out‐of‐hospital setting for the management of SAWHI. Study data from a published multicentre randomised controlled trial were used and represented 221 patients that received care in the out‐of‐hospital setting. The mean per‐patient total cost within 42 days was slightly higher in the negative pressure wound therapy group (2034.98 € versus 1918.91 €); however, when wound closure rates were considered, a cost savings of 4155.98 € per closed wound was observed with the use of negative pressure wound therapy (4324.34 € versus 8480.32 €). A cost‐effectiveness analysis was constructed, and negative pressure wound therapy was observed to have a lower cost of care and a higher incremental closure rate.
Background: Incisional surgical site infections (iSSI) in hepatopancreatobiliary (HPB) surgery usually lead to prolonged hospital stays, consume valuable resources, and impact on patients’ outcome. Prophylactic closed incision negative pressure wound therapy (ciNPWT) to decrease wound complications has become available. Owing to an increasing number of studies, evidence for superiority in many indication areas has accumulated; however, in general surgery, there are a few data and those have shown contradictory results. Methods: In this monocentric, prospective, randomized, controlled, two-armed study, the influence of ciNPWT on incisional surgical site infection rates after HPB operations will be investigated. A total of 222 patients will be randomized 1:1 to an interventional group (7-day treatment with ciNPWT) or a control group (treated with gauze dressing). The primary parameter to evaluate efficacy is the rate of incisional SSIs within 30 days after surgery. Additionally, several clinically relevant secondary outcomes will be assessed. Discussion: A reduction in the rate of incisional SSIs would not only lead to a significant cost reduction and shorter postoperative length of stay, but may also improve postoperative quality of life for patients. While earlier publications have shown advantages for ciNPWT, recent studies did not confirm a positive effect regarding iSSI rate. Even if iSSI rate is not reduced, findings obtained from the secondary endpoints may be of clinical relevance, such as reduction of wound complication rates. Trial registration: This trial has been registered in the German Clinical Trials Register, DRKS 00015136. Registered on 19 February 2019 and has been approved by the local ethics committee of the University of Regensburg: 18-1225-101.
