MRI studies after treatment of brain tumors in childhood and adolescence
1986
Forty-seven children and adolescents with brain tumors were examined by magnetic resonance imaging (MRI) after tumor resection. The typical changes and complications after surgery and chemotherapy, as well as the corresponding MRI findings, are discussed. Typical examples of boundary-layer lesions, tumor recurrences, hydrocephalus, porencephalic cysts, and hygromas are given.
Sarcoma of the pulmonary artery: Report of two cases and a review of the literature
1992
Primary tumours of the pulmonary arteries are rare neoplasms seldom diagnosed during the patient's life time. We report on two cases of pulmonary artery sarcomas diagnosed during life time of the respective patients in intra-operative frozen sections by histopathological examination. Case 1 was of a 55-year-old man with a fibrosarcoma originating from the main pulmonary trunk. Case 2 was of a 43-year-old woman with a malignant fibrous histiocytoma originating from the right pulmonary artery. In both patients a radical tumour resection under cardiopulmonary bypass was attempted. Both patients, however, had a local tumour recurrence and died 18 months (patient 1) and 6 months (patient 2) afte…
Klatskin Tumour: Meticulous Preoperative Work-Up and Resection Rate
2011
BACKGROUND: Surgery represents the only potentially curative treatment of hilar cholangiocarcinoma (hilCC). It may be suggested that meticulous preoperative work-up in Asian countries leads to higher resection rates. METHOD: One hundred and eighty-two patients treated in our department between 1998 and 2008 were included in an analysis based on our prospectively recorded database. Among them, 75 % had a percutaneous transhepatic cholangiography as part of their diagnostic work-up. A total of 160 patients underwent explorative surgery and 123 patients were resected (77 % of patients undergoing exploration, 68 % of all patients). RESULTS: Ninety-one percent of the patients were diagnosed to h…
Minimally Invasive Pelvic Exenteration for Gynecologic Malignancies: A Multi-Institutional Case Series and Review of the Literature.
2019
ABSTRACT Study Objective To assess the feasibility and efficacy of minimally invasive pelvic exenteration (MIPE) in a multi-institutional Italian case series of women with gynecologic cancer and a review of the literature. Design Retrospective cohort study (Canadian Task Force classification II-2). Setting Three Italian university/teaching hospitals: “Agostino Gemelli” Foundation University Hospital in Rome, "ARNAS Civico Di Cristina Benfratelli” Hospital in Palermo, and “Maggiore della Carita” Hospital in Novara. Patients We reviewed all consecutive cases with gynecologic malignancies in this multi-institutional setting recorded between March 2014 and June 2017. Women with primary or centr…
Myxofibroma of the maxilla. Reconstruction with iliac crest graft and dental implants after tumor resection
2010
Odontogenic fibromyxomas are benign odontogenic tumors of mesenchymal origin of rare presentation in the oral cavity, which exhibit locally aggressive behavior and are prone to local recurrence. The controversy has mainly been on therapeutic management with recommendations varying, depending on the clinical cases, from simple curettage of lesion to segmental bone resection. We present a case report describing the reconstruction of an osseous defect in the maxilla and the restoration with dental implants in a 32 year old female patient after radical surgical excision due to an odontogenic fibromyxoma with locally aggressive behavior. The primary reconstruction of maxillary discontinuity defe…
Identification of High-Risk Atypical Meningiomas According to Semantic and Radiomic Features
2020
Up to 60% of atypical meningiomas (World Health Organization (WHO) grade II) reoccur within 5 years after resection. However, no clear radiological criteria exist to identify tumors with higher risk of relapse. In this study, we aimed to assess the association of certain radiomic and semantic features of atypical meningiomas in MRI with tumor recurrence. We identified patients operated on primary atypical meningiomas in our department from 2007 to 2017. An analysis of 13 quantitatively defined radiomic and 11 qualitatively defined semantic criteria was performed based on preoperative MRI scans. Imaging characteristics were assessed along with clinical and survival data. The analysis include…
Laparoscopic Total Mesometrial Resection (L-TMMR)
2017
Abdominal radical hysterectomy and pelvic lymph node dis- section as introduced by Wertheim and Meigs [1–2] first in the beginning of the century is still regarded as “gold stan- dard” in the surgical treatment of the uterine cervix carci- noma, FIGO stages IA2-IB and IIA. The resection of the parametrial and paracervical tissues proposed by the conventional radical hysterectomy is based on a “centrifu- gal diffusion” from the center of the tumor on the direction of the parametrial (dorsal, lateral and ventral) highways. This imply a classic functional and ligament-focused view of the surgical anatomy.
Dense drug-eluting biodegradable Fe-Ag nanocomposites
2021
Abstract Biodegradable metals in orthopedics are aimed to eliminate secondary the surgical intervention for implant removal, and thus improve patient compliance, reduce surgery costs and the risk of infections. In addition, biodegradable implants could be loaded with different drugs to prevent the growth of pathogens and the development of bone infections, kill remaining cancer cells after tumor resection or stimulate bone regeneration. However, drugs undergo thermal decomposition under the conditions of conventional metal fabrication processes. In this work, we describe the fabrication of a dense drug-eluting biodegradable Fe-Ag nanocomposite containing 10 vol% of Ag and loaded with the an…
Chirurgische, endoskopische oder radiologisch interventionelle Therapie beim Gallengangscarcinom
1990
Die Therapie des Gallengangscarcinoms wird unter dem Eindruck der endoskopischen Behandlungsmoglichkeiten teilweise kontrovers diskutiert. Wenngleich ein Vergleich zwischen den Patienten die chirurgisch und denen die endoskopisch bzw. radiologisch interventionell behandelt wurden aufgrund der unterschiedlichen Zusammensetzung der verschiedenen Patientenkollektive nicht moglich ist, zeigen doch retrospektive Arbeiten, das ein wesentlicher Unterschied in der 30-Tage-Letalitat nicht besteht. Kontrollierte oder gar randomisierte Studien liegen allerdings zu dieser Frage und zur Problematik der Lebensqualitat nicht vor. Bisherige retrospektive Arbeiten zeigen jedoch, das die nichtchirurgischen V…
EP756 Laterally extended endopelvic resection: a comparative analysis between laparotomic and laparoscopically modified approach
2019
Introduction/Background Laterally Extended Endopelvic Resection (LEER) has been identified as a valid therapeutic option for women with gynecological malignancies involving the pelvic side wall. The historical approach to LEER is laparotomic, recently we have proposed the so called Laparoscopically Modified Laterally Extended Endopelvic Resection (LM-LEER).The objective of this study is to compare surgical and oncological outcomes between LEER and LM-LEER in a consecutive series of patients with gynecological malignancies infiltrating the pelvic side wall. Methodology We retrospectively evaluated women submitted to LEER between October 2012 and January 2019. Inclusion criteria for LM-LEER w…
