Minimal-invasive hepatectomy (MIH) has been increasingly performed for benign and malignant liver lesions with most promising short-term results. However, the oncological role of MIH in the treatment of patients with colorectal liver metastases (CRLM) needs further investigation. Clinicopathological data of patients who underwent liver resection for CRLM between 2012 and 2017 at the Department of Surgery, Charité-Universitätsmedizin Berlin, and the Inselspital Bern were assessed. Postoperative outcomes und long-term survivals of patients following MIH were compared with those after conventional open hepatectomy (OH) after 1:1 propensity score matching. During the study period, 229 and 91 patients underwent liver resection for CRLM at the Charité Berlin and the Inselspital Bern, respectively. Patients who underwent MIH in one of the two centers (n = 69) were compared with a matched cohort of patients who underwent OH. MIH was associated with lower complication rates (23% vs. 44%, p = 0.011), shorter length of intensive care unit stay (ICU, 1 vs. 2 days, p = 0.043), shorter length of hospital stay (7 vs. 11 days, p < 0.0001), and a reduced need for intraoperative transfusions (12% vs. 25%, p = 0.047) compared to OH. R0 status was achieved in 93% and 75% of patients after MIH and OH, respectively (p = 0.005). After a median follow-up of 31 months, MIH resulted in similar five-year overall survival (OS) rate (56% vs. 48%, p = 0.116) in comparison to OH. MIH for CRLM is associated with lower postoperative morbidity, shorter length of ICU and hospital stay, reduced need for transfusions, and comparable oncologic outcomes compared to the established OH. Our findings suggest that MIH should be considered as the preferred method for the treatment of curatively resectable CRLM.

Abdominal wall closure after pediatric liver transplantation (pLT) in infants may be hampered by graft‐to‐recipient size discrepancy. Herein, we describe the use of a porcine dermal collagen acellular graft (PDCG) as a biological mesh (BM) for abdominal wall closure in pLT recipients. Patients <2 years of age, who underwent pLT from 2011 to 2014, were analyzed, divided into definite abdominal wall closure with and without implantation of a BM. Primary end‐point was the occurrence of postoperative abdominal wall infection. Secondary end‐points included 1‐ and 5‐year patient and graft survival and the development of abdominal wall hernia. In five out of 21 pLT recipients (23.8%), direct abdominal wall closure was achieved, whereas 16 recipients (76.2%) received a BM. BM removal was necessary in one patient (6.3%) due to abdominal wall infection, whereas no abdominal wall infection occurred in the no‐BM group. No significant differences between the two groups were observed for 1‐ and 5‐year patient and graft survival. Two late abdominal wall hernias were observed in the BM group vs none in the no‐BM group. Definite abdominal wall closure with a BM after pLT is feasible and safe when direct closure cannot be achieved with comparable postoperative patient and graft survival rates.

BackgroundOver the course of the COVID-19 pandemic, previous studies have shown that the physical as well as the mental health of children and adolescents significantly deteriorated. Future anxiety caused by the COVID-19 pandemic and its associations with quality of life has not previously been examined in school children.MethodsAs part of a cross-sectional web-based survey at schools in Mecklenburg-Western Pomerania, Germany, two years after the outbreak of the pandemic, school children were asked about COVID-19-related future anxiety using the German epidemic-related Dark Future Scale for children (eDFS-K). Health-related quality of life (HRQoL) was assessed using the self-reported KIDSCREEN-10. The eDFS-K was psychometrically analyzed (internal consistency and confirmatory factor analysis) and thereafter examined as a predictor of HRQoL in a general linear regression model.ResultsA total of N = 840 8–18-year-old children and adolescents were included in the analysis. The eDFS-K demonstrated adequate internal consistency reliability (Cronbach's α = 0.77), and the confirmatory factor analysis further supported the one-factor structure of the four-item scale with an acceptable model fit. Over 43% of students were found to have low HRQoL. In addition, 47% of the students sometimes to often reported COVID-19-related fears about the future. Children with COVID-19-related future anxiety had significantly lower HRQoL (B = – 0.94, p &lt; 0.001). Other predictors of lower HRQoL were older age (B = – 0.63, p &lt; 0.001), and female (B = – 3.12, p &lt; 0.001) and diverse (B = – 6.82, p &lt; 0.001) gender.ConclusionTwo years after the outbreak of the pandemic, school-aged children continue to exhibit low HRQoL, which is further exacerbated in the presence of COVID-19-related future anxiety. Intervention programs with an increased focus on mental health also addressing future anxiety should be provided.

Background: Laparoscopic techniques have become the standard approach for most liver resections.Clinical studies providing conclusive evidence which patients benefit most from minimal-invasive surgery remain limited.Methods: We retrospectively analyzed data of all consecutive cases of laparoscopic liver resection between 2015 and 2018 at our center. We compared patients with and without prior abdominal surgeries with respect to postoperative complications (Clavien-Dindo score), length of operation, length of ICU stay and length of hospitalization in univariate and multivariate analyses. Results: Within the study period 319 patients underwent laparoscopic liver resections, 44% of which had a history of abdominal surgeries. Pre-operative characteristics were similar to patients without prior surgeries. Both groups showed comparable rates of post-operative complications (Clavien-Dindo score 3a; 12% in patients without vs. 16% with prior surgeries, p = 0,322). There were no significant differences in length of surgery or length of stay in the ICU or in the hospital. Conclusion:Our data suggest that history of prior abdominal surgery is not a risk factor for postoperative complications after laparoscopic liver resection. We conclude that prior abdominal surgery should not be considered a contra-indication for laparoscopic approach in liver resection.
