Air leak and intraoperative bleeding in thoracic surgery: a Delphi consensus among the members of Italian society of thoracic surgery.

Background: Persistent air leak and the management of intraoperative blood loss are common threats in thoracic surgical practice. The availability of new procedures, technology and materials is constantly evolving topical hemostats and surgical sealants must be added to this toolkit. Topical hemostats and surgical sealants differ according to their chemical nature and physical characteristics, to their origin and mechanism of action, regulatory/registration and vigilance paths. A Delphi consensus was set to highlight the different points of view on the use of topical haemostatic products and sealants among the members of Italian Society of thoracic surgery. Methods: The board was formed by a group of five Italian experts; in the first phase after a careful review of the scientific literature and two rounds, the board finally generated 16 consensus statements for testing across a wider audience. During the second phase, the statements were collated into a questionnaire, which was electronically sent to a panel of 46 Italian surgeons, experts in the field. Results: Out of 46 Italian surgeons, 33 (72%) panel members responded to the Delphi questionnaire. All the items reached a positive consensus, with elevated levels of agreement, as demonstrated by the presence of a 100% consensus for nine items. For the remaining 7 statements the minimum level of consent was 88% (29 participants approved the statement and 4 disagreed) and the maximum was 97% (32 participants approved the statement and 1 was in disagreement). Conclusions: The present Delphi analysis shows that air leak and intraoperative bleeding are clinical problems well known among thoracic surgeons. Nevertheless, the aim of the scientific societies and of the group of experts is to execute the education activities in the surgery community. This Delphi survey suggest the need of wider and updated scientific information about technical and registration characteristics of most recent technologic solutions, such as the of topical hemostats and surgical sealants to provide healthcare and administrative staff with the opportunity to work and interact through a common and shared language and eventually to guarantee minimal requirements of assistance.

Stenting of the superior vena cava and right pulmonary artery in a woman with a mediastinal mass and acute respiratory distress syndrome (ARDS).

We report the case of a woman with a mass in the anterior and middle mediastinum (a non-small-cell lung carcinoma), determining significant compression of both superior vena cava and right pulmonary artery. The patient developed acute respiratory distress syndrome , necessitating intubation and admission to the Intensive Care Unit . Radiotherapy sessions to reduce the mass effect were attempted, without significant clinical improvement. Due to the persistence of severe hypoxemia, stenting of the superior vena cava and the right pulmonary artery was performed, the latter resulting in a significant improvement of the arterial blood gas parameters, allowing extubation of the patient. In our opinion, stenting of the superior vena cava and the pulmonary artery (or its branches) is an effective and safe treatment; it should be considered in similar cases, especially if other - less invasive - treatments fail.

Virtual Multidisciplinary Tumor Boards: A Narrative Review Focused on Lung Cancer.

To date, the virtual multidisciplinary tumor boards (vMTBs) are increasingly used to achieve high-quality treatment recommendations across health-care regions, which expands and develops the local MTB team to a regional or national expert network. This review describes the process of lung cancer-specific MTBs and the transition process from face-to-face tumor boards to virtual ones. The review also focuses on the project organization's description, advantages, and disadvantages. Semi-structured interviews identified five major themes for MTBs: current practice, attitudes, enablers, barriers, and benefits for the MTB. MTB teams exhibited positive responses to modeled data feedback. Virtualization reduces time spent for travel, allowing easier and timely patient discussions. This process requires a secure web platform to assure the respect of patients' privacy and presents the same unanswered problems. The implementation of vMTB also permits the implementation of networks especially in areas with geographical barriers facilitating interaction between large referral cancer centers and tertiary or community hospitals as well as easier access to clinical trial opportunities. Studies aimed to improve preparations, structure, and conduct of MTBs, research methods to monitor their performance, teamwork, and outcomes are also outlined in this article. Analysis of literature shows that MTB participants discuss 5-8 cases per meeting and that the use of a vMTB for lung cancer and in particular stage III NSCLC and complex stage IV cases is widely accepted by most health professionals. Despite still-existing gaps, overall vMTB represents a unique opportunity to optimize patient management in a patient-centered approach.

Primary Aorto-Duodenal Fistula in Association with Chronic Ischemic Enteritis: A Case Report.

BACKGROUND: Primary aorto-duodenal fistula (PADF) is a rare but life-threatening condition that should be taken into account when considering upper gastrointestinal bleeding in elderly patients with history of abdominal aortic aneurysm. Unfortunately, its diagnosis is often unsuspected until surgery or at postmortem. PRESENTATION OF CASE: We report a case of a 69 years old man with massive gastrointestinal bleeding secondary to a primary aortic duodenal fistula without a history of abdominal aortic aneurysm and with a misleading diagnosis of chronic ischemic enteritis. Repeated endoscopies and a prior CT angiography failed to document a proper diagnosis. Finally, the aorto-duodenal fistula was identified with a further abdominal CT angiography. Despite a prompt endovascular treatment with aortic endoprosthesis placement, the patient died due to a severe hemorrhagic shock consequent to the massive blood loss. DISCUSSION: Primary aorto-duodenal fistula represents a very rare (<0.1% of incidence) cause of severe upper gastrointestinal bleeding most often leading to patient's death for hemorrhagic shock. It is frequently associated to aortic atherosclerosis. Its prompt diagnosis with endoscopy and CT angiography is very often difficult and almost never immediate. Furthermore, these exams may be misleading. In case of massive upper GI bleeding without a certain diagnosis in patients with severe aortic atherosclerosis, laparotomy with careful inspection of the distal duodenum is strongly recommended for aortic repair and bowel suture. CONCLUSIONS: The diagnosis of PADF should be taken into account in patients with upper gastrointestinal bleeding associated with aortic atherosclerosis with strong suspect of penetrating ulcer.

Prognostic and predictive value of combined HE-4 and CA-125 biomarkers during chemotherapy in patients with epithelial ovarian cancer.

INTRODUCTION: At present there is no predictive value univocally associated with the success of chemotherapy. Biomarkers produced by ovarian cancer (HE4 and Ca125) could have a good prognostic significance. The aim of this study is to prove the ability of biomarkers to identify patients with the highest risk of non-optimal response during the chemotherapy, and to predict which patients will most likely develop recurrence of disease. METHODS: We analyzed 78 patients with epithelial ovarian cancers who underwent surgery in the biennium 2016-2017. All the patients underwent chemotherapy after surgery or interval debulking surgery following neoadjuvant therapy. Serum levels of HE4 and Ca125 were measured at diagnosis and at each cycle of chemotherapy. We established the degree of response to the treatment by computed tomography scan, and the patients were followed up (median: 10 months). The parameters of progression-free survival and disease-free survival were related to serum levels of biomarkers. RESULTS: Both CA125 and HE4 values became negative at the fourth cycle in the patients with good response to chemotherapy. HE4 increased earlier than Ca125. The parameters that best correlated with a long progression-free survival were: negativization of the marker after the third cycle of chemotherapy (HE4: odds ratio (OR) 5.5; Ca125: OR 9.1) and biomarker serum levels lower than the mean value in the affected population at the time of diagnosis (HE4: OR 3.4; Ca125: OR 3.7). CONCLUSIONS: We can conclude that the monitoring of HE4 and Ca125 during chemotherapy, especially at the third cycle, is recommended, because their variation is a good prognostic factor.

Type III pleuropulmonary blastoma in a 7-month-old female baby with impending respiratory failure: a case report.

INTRODUCTION: Pleuropulmonary blastoma is a very rare, aggressive, embryonal pulmonary neoplasm which mostly affects children under the age of 5. According to the histopathological features, three subtypes of pleuropulmonary blastoma have been recognized: type I (purely cystic), type II (grossly visible cystic and solid elements) and type III (purely solid). Characteristics of type I and type II blastoma allow an earlier diagnosis compared with type III. Here we present a case report of an unusual presentation of type III pleuropulmonary blastoma. CASE PRESENTATION: We describe the case of a 7-month-old female baby of Italian mother and Kurdish father who was diagnosed with type III pleuropulmonary blastoma, which entirely occupied her right hemithorax. CONCLUSIONS: The reported case is an unusual presentation because type III pleuropulmonary blastoma typically occurs in older children. The complete re-expansion of her residual, previously totally compressed, right lung observed immediately after the resection of the lesion suggests an atypical rapid growth of this embryonal tumor in the late phase of gestation or after delivery. This case report suggests that, in addition to other childhood tumors, type III pleuropulmonary blastoma should be included in the differential diagnosis of solid nonhomogeneous thoracic large masses, compressing the mediastinal and chest wall structures in infants. This is an original case report of interest for several specialities such us pediatrics, radiology, surgery and oncology.

Paclitaxel, carboplatin and gemcitabine combination as induction chemotherapy for stage IIIA N2 bulky non-small cell lung cancer.

BACKGROUND: Induction chemotherapy followed by surgical resection or definitive radiotherapy for patients affected by stage IIIA N2 bulky non-small cell lung cancer (NSCLC) has been investigated in several trials. PATIENTS AND METHODS: In this present study, 52 patients with stage IIIA N2 bulky NSCLC with cytologically or histologically confirmed mediastinal lymph node involvement received paclitaxel 175 mg/mq on day 1, carboplatin AUC 5 on day 1 and gemcitabine 1,000 mg/mq on day 1 and 8 every 3 weeks for three cycles as induction chemotherapy. RESULTS: Objective response (4 complete remission and 36 partial remission) was achieved in 40/52 patients. No early or toxic deaths were observed. Twenty-two patients were surgically explored. Fifteen were excluded for resection for biopsy-proven residual tumour in mediastinal nodes. Complete surgical resection was performed in 15 patients with confirmed pathological downstaging. Pathological complete response was achieved in 4 patients. No surgery-related mortality or significant morbidity was reported. Adjuvant radiotherapy was delivered in 15 patients, and 30 patients received definitive radiotherapy. CONCLUSION: In the present study, the combination of paclitaxel, carboplatin and gemcitabine has been a safe and active regimen in poor-prognosis stage IIIA N2 bulky NSCLC.
