Full text linkA 71-year-old man presented with a thymic mass involving the superior vena cava. A mediastinoscopical biopsy initially suggested a diagnosis of type A thymoma. After neoadjuvant chemotherapy, the patient underwent en-bloc thymectomy and vascular resection for a pathology-confirmed type B3 thymoma involving the superior vena cava, the left brachiocephalic vein and the distal part of the right brachiocephalic vein. Adjuvant radiotherapy was administered. Two years after the primary surgery, abdominal computed tomography (CT) and whole body fluorodeoxyglucose (18-FDG) positron emission tomography (PET) scans showed a single hepatic lesion that was treated with wedge liver resection. Pathological examination confirmed metastatic type B3 thymoma. Almost 4 years later, abdominal CT and 18-FDG PET revealed a 2.9-cm solid mass involving the body of the pancreas. Distal pancreatectomy with lymph node dissection was performed. Pathological examination showed a pancreatic metastasis from a type B3 thymoma, without lymph node involvement. The patient is alive and free of disease 6 months after the pancreatectomy (68 months after the initial thymectomy surgery). Intra-abdominal recurrence and pancreatic metastases are very uncommon manifestations of thymoma, but this event should be kept in mind when an abdominal mass is seen during follow-up
International Guidelines And Recommendations For Surgery During Covid-19 Pandemic: A Systematic Review
No full textDuring the COVID-19 pandemic, surgical departments were forced to re-schedule their activity giving priority to urgent procedures and non-deferrable oncological cases. There is a lack of evidence-based literature providing clinical and organizational guidelines for the management of a general surgery department. Aim of our study was to review the available recommendations published by general Surgery Societies and Health Institutions and evaluate the underlying Literature
Simultaneous laparoscopic resection of distal pancreas and liver nodule for pancreatic neuroendocrine tumor
Full text linkLaparoscopic distal pancreatectomy (LDP) with or without splenic preservation is increasingly performed for benign or border-line neoplasms of the body and tail of the pancreas. Pancreatic neuroendocrine tumors appear as an excellent indication for laparoscopic resection and this procedure is becoming the gold standard for the surgical treatment of such neoplasms. The safety and advantage of laparoscopic resection over open distal pancreatectomy (ODP) have been proven. In this video, we present a LDP with splenectomy for a neuroendocrine tumor of distal pancreas, with associated wedge resection of a liver nodule. Technical considerations were also discussed
Metastatic tumors to the pancreas: a systematic review and meta-analysis
Full text linkINTRODUCTION:
Metastases to the pancreas from other primary tumors are increasingly recognized in clinical practice, but the real role of surgery remains unclear. This study was designated to evaluate by a meta-analytic approach the results of surgical treatment for the most common malignancies metastasizing to the pancreas.
EVIDENCE ACQUISITION:
MEDLINE, PubMED, Scopus and Web of Sciences were searched from January 2000 to December 2015. Studies reporting postoperative complications, postoperative mortality, disease-free and overall survival of patients undergoing resection for secondary tumours of the pancreas, were included.
EVIDENCE SYNTHESIS:
Fourteen publication with 281 patients met the inclusion criteria and were subjected to the analysis. Operative morbidity and mortality were 34% and 1.3% respectively. Pancreatic resection for renal cell cancer showed better survival compared to other non-renal cell cancer (ratio of mean 1.83; 95% CI: 1.42-2.36, I2=74.52%, P<0.001). Disease-free interval was longer for metastatic renal cell carcinoma patients (mean difference 6.36, 95% CI: 3.803-8.912 years, I2=76:54%, P<0.001). A meta-regression was used to correlate the two endpoints and showed that a longer DFI is associated to a longer survival.
CONCLUSIONS:
Pancreatic resection for metastasis should be reserved to patients in good health conditions, with isolated disease from renal cell cancer. For other types of tumor, surgery should be performed only in individual basis. There is a need of studies evaluating the role of chemotherapy in the neoadjuvant setting or the best sequential use of multimodality treatment (targeted therapy, radiotherapy, surgery, etc.)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
PET/CT incidental detection of second tumor in patients investigated for pancreatic neoplasms
Full text linkPositron Emission Tomography/computed tomography (PET/CT) is an imaging technique which has a role in the detection and staging malignancies (both in first diagnosis and follow-up). The finding of an unexpected region of FDG (Fluorodeoxyglucose) uptake can occur when performing whole-body FDG-PET, raising the possibility of a second primary tumor. The aim of this study was to evaluate our experience of second primary cancer incidentally discovered during PET/CT examination performed for pancreatic diseases, during the initial work-up or follow-up after surgical resection
