Second Look After Retromuscular Repair With the Combination of Absorbable and Permanent Meshes.
Objective: The aim of this study is to describe the macroscopic features and histologic
details observed after retromuscular abdominal wall reconstruction with the combination
of an absorbable mesh and a permanent mesh.
Methods: We have considered all patients that underwent abdominal wall
reconstruction (AWR) with the combination of two meshes that required to be reoperated
for any reason. Data was extracted from a prospective multicenter study from 2012 to
2019.Macroscopic evaluation of parietal adhesions and histological analysis were carried
out in this group of patients.
Results: Among 466 patients with AWR, we identified 26 patients that underwent a
reoperation after abdominal wall reconstruction using absorbable and permanent mesh.
In eight patients, the reoperation was related to abdominal wall issues: four patients were
reoperated due to recurrence, three patients required an operation for chronic mesh
infection and one patient for symptomatic bulging. A miscellanea of pathologies was
the cause for reoperation in 18 patients. During the second surgical procedures made
after a minimum of 3 months follow-up, a fibrous tissue between the permanent mesh
covering and protecting the peritoneum was identified. This fibrous tissue facilitated blunt
dissection between the permanent material and the peritoneum. Samples of this tissue
were obtained for histological examination. No case of severe adhesions to the abdominal
wall was seen. In four cases, the reoperation could be carried out laparoscopically with
minimal adhesions from the previous procedure.
Conclusions: The reoperations performed after the combination of absorbable and
permanent meshes have shown that the absorbable mesh acts as a protective barrier
and is replaced by a fibrous layer rich in collagen. In the cases requiring new hernia
repair, the layer between peritoneum and permanent mesh could be dissected without
special difficulty. Few intraperitoneal adhesions to the abdominal wall were observed,
mainly filmy, easy to detach, facilitating reoperations.post-print6360 K
The management of acute venous thromboembolism in clinical practice - study rationale and protocol of the European PREFER in VTE Registry
Background: Venous thromboembolism (VTE) is a major health problem, with over one million events every year in Europe. However, there is a paucity of data on the current management in real life, including factors influencing treatment pathways, patient satisfaction, quality of life (QoL), and utilization of health care resources and the corresponding costs. The PREFER in VTE registry has been designed to address this and to understand medical care and needs as well as potential gaps for improvement. Methods/design: The PREFER in VTE registry was a prospective, observational, multicenter study conducted in seven European countries including Austria, France Germany, Italy, Spain, Switzerland, and the UK to assess the characteristics and the management of patients with VTE, the use of health care resources, and to provide data to estimate the costs for 12 months treatment following a first-time and/or recurrent VTE diagnosed in hospitals or specialized or primary care centers. In addition, existing anticoagulant treatment patterns, patient pathways, clinical outcomes, treatment satisfaction, and health related QoL were documented. The centers were chosen to reflect the care environment in which patients with VTE are managed in each of the participating countries. Patients were eligible to be enrolled into the registry if they were at least 18 years old, had a symptomatic, objectively confirmed first time or recurrent acute VTE defined as either distal or proximal deep vein thrombosis, pulmonary embolism or both. After the baseline visit at the time of the acute VTE event, further follow-up documentations occurred at 1, 3, 6 and 12 months. Follow-up data was collected by either routinely scheduled visits or by telephone calls. Results: Overall, 381 centers participated, which enrolled 3,545 patients during an observational period of 1 year. Conclusion: The PREFER in VTE registry will provide valuable insights into the characteristics of patients with VTE and their acute and mid-term management, as well as into drug utilization and the use of health care resources in acute first-time and/or recurrent VTE across Europe in clinical practice.
