Acquired benign tracheo­oesophageal fistula secondary to oesophageal stenting for post lye ingestion stenosis: A case report.

Acquired benign trachea-oesophageal fistula is a rare benign pathological entity with varying aetiologies that most often occurs post-intubation. This case report presents the case of a female patient, 31 years old, admitted to the emergency room with sepsis syndrome following bilateral aspiration pneumonia caused by a large trachea-oesophageal fistula. The fistula was the result of intra-tracheal migration of an oesophageal stent placed for post lye ingestion stenosis. Esophageal diversion and partial resection with oesophageal patch to repair the tracheal defect, under general anaesthesia with ventilation using rigid bronchoscopy and high frequency jet ventilation (HFJV), followed at a later date by esophageal replacement with colic graft were the procedures performed with a view to curing the patient. In conclusion, complex cases always require a tailored approach. It is important to note that HFJV may be applied for a longer period of time and the oesophagus can be used as patch for the posterior tracheal wall in selected cases. Staged surgery is also an option when the patients' poor health status does not permit major surgery.

Gastric Pull-up: A Back-up Surgical Solution in the Treatment of Large Hiatal Hernias.

The laparoscopic treatment of the hiatal hernias is nowadays the standard procedure. However, due to the volume and the age of the affliction, there are some situations in which the classical approach is indicated. The latter is associated with specific risks. The appearance of some intra-operatory incidents or accidents could lead to changes in the tactics and the techniques, moreover the abandon of the classical procedure and the use of alternative solutions. These procedures are meant to solve the case with minimum negative effects on the patient. This article presents the case of a 62 year-old female patient, diagnosed with a large type II hiatal hernia on which the surgical team had to intervene through a median xypho-umbilical laparotomy. During the attempt to perform the Nissen procedure, the irreversible lesion of the abdominal esophagus occurred, the esophageal wall having already suffered because of the esophagitis. This led to the restoring of the gastric continuity using the gastric pull-up technique and a cervical anastomosis. The remaining esophagus was removed during the second procedure, 3 moths later. The immediate and the late evolution of the patient was excellent.

Synchronous arterial resection in pancreatic cancer: A case report.

Pancreatic cancer is one of the most lethal malignancies affecting people worldwide. As it is frequently diagnosed in advanced stages of the disease, the 5-year overall survival rate is <10%. Advanced stages are usually characterized by the local invasion of the superior mesenteric axis, celiac axis and portal vein and are considered a sign of unresectable cancer. The association between venous resections and survival outcomes has been widely reported. The effect of arterial invasion remains unclear as only isolated cases have been reported thus far. The present study investigated the preliminary experience in the field of arterial resection for locally advanced pancreatic cancer. Between January 2018 and January 2020 arterial resection was successfully associated with pancreatoduodenectomy in four cases. The mean age at the time of surgery was 48 years, and in all cases the indication of resection was represented by pancreatic head adenocarcinoma. Different types of venous resections were required in all cases. Postoperative reoperation was required in one case, while histopathological studies confirmed microscopic negative resection margins in all but one case. In selected cases, combined pancreatoduodenectomy with venous and arterial resection may be required to increase the chances of radical surgery.

Minimally Invasive Thoracic Surgery - Video Assisted Thoracic Surgery: Technique and Indications.

Video-Assisted Thoracic Surgery (VATS) is already practised worldwide, in almost every condition addressed by open thoracic surgery. As part of minimally invasive thoracic surgery (MITS), VATS offers to patients and to healthcare providers excellent results and great satisfactions. Learning and performing VATS use different pathways in trainees and in experienced surgeons. This article presents VATS in its essence: classification, indications, contraindications, instruments and tools, incisions and access, troubleshooting, learning curve and training. We wish that the information helps our colleagues, both trainees and experienced thoracic surgeons, to start and continue performing VATS as standard care in thoracic surgery.

Anatomical remodeling of the aortic wall in relation with the cause of death.

AIM: The authors set out to evaluate the correlations between three of the main morphological aortic parameters (aortic diameter, intima, and media thickness) and the cause of death. MATERIALS AND METHODS: Study group included 28 people died of a cardiovascular (CV) disease and 62 people died of a noncardiovascular (NCV) disease. Four aortic cross-sections (base, cross, thoracic, abdominal) were collected during autopsy from the selected cases, fixed in 10% buffered formalin and photographed together with a calibrating ruler. Then, they were processed using the classical histopathological (HP) technique (formalin fixation and paraffin embedding), stained with Hematoxylin-Eosin (HE) and Orcein, and the obtained histological slides were transformed into virtual slides. Aortic diameters were determined on calibrated photos using a custom-made software, developed in MATLAB (MathWorks, USA). Intima and media thicknesses were determined on virtual slides using a dedicated image analysis software. RESULTS AND DISCUSSIONS: The most frequent CV causes of death were the ischemic heart diseases and the most frequent NCV causes of death were the inflammatory diseases. Aortic diameter decreased from the aortic origin till the aortic end, with larger values in women than in men and in CV diseases than in NCV diseases. The difference in the remodeling of the aortic diameter between the two groups is smaller towards the abdominal region. Intima thickness increased from the aortic origin till the aortic end and was larger especially in women died of CV diseases, whereas in men there were some shifts at the extremities of the aorta. The difference in the remodeling of the intimal thickness between the two groups is extremely variable. Media was thicker in almost all of its segments in CV group than in NCV. It was a divergent evolution of the correlation degree trends in the two groups. CONCLUSIONS: The three morphological parameters of the aorta (diameter, intima, and media thicknesses) are more or less influenced by the pathological status that caused patient's death by the patient's sex and by the topographic region where the measurement was made.

Assessment of the aortic wall histological changes with ageing.

AIM: The authors aimed to quantitatively assess the variation with age of three of the main components of the aortic wall, namely elastic fibers (FE) and collagen fibers [FC(COL)], and smooth muscle cells (SMCs). MATERIALS AND METHODS: Four aortic cross sections (base, cross, thoracic, abdominal) were collected during autopsy from 90 cases of all ages, processed using the classical histopathological (HP) technique (formalin fixation and paraffin embedding) and stained with Orcein and Goldner's trichrome. The obtained histological slides were transformed into virtual slides. Quantitative measurements of the three components were made on identical regions of interest (ROIs) selected from two-paired slides stained with the above-mentioned techniques using custom-made software, developed in MATLAB (MathWorks, USA). RESULTS AND DISCUSSIONS: FE revealed an obvious decreasing general trend with age, present at all four levels of investigation. Smooth muscle fibers (FM) density showed almost no variation with age regardless of the level at which the measurement was made. FC(COL) density had an obvious increasing trend with age, expressed in all four aortic regions FE densities and FM densities were higher in men than in women, while FC(COL) densities were higher in women than in men in three of the aortic regions excepting, in all cases, the cross region. CONCLUSIONS: There were differences between men and women concerning the composition of aortic wall cellular and extracellular compartments. FE and FC(COL) dominated the age-related remodeling process of the aortic wall. The process evolved in the same way in all regions of the aorta. Studies need to be continued to define more clearly this complex process of vascular wall remodeling with aging.

Infra-hepatic caval resection en bloc with right nephrectomy followed by caval reconstruction for locally advanced caval leiomyosarcoma: A case report and literature review.

Retroperitoneal sarcomas often require complex surgical procedures in order to achieve complete resection; in such cases both vascular and visceral resections are needed. When it comes to the need for vascular reconstruction, the type of graft as well as the type of reconstructive process are chosen according to the length and location of the resected segment. Meanwhile, depending on the location of the resected segment, other vascular reconstructions may be needed such as the reimplantation of the renal veins. However, in certain cases, this reimplantation is not mandatory, an adequate renal outflow being reported through the collateral network at this level. We present the case of a 43-year-old patient diagnosed with a large retroperitoneal sarcoma originating from the cava vein invading the right kidney. Resection of the tumor was performed en bloc with caval resection and right nephrectomy, without reimplantation of the left renal vein at the level of the graft. Extended visceral and vascular resections might be needed in order to achieve complete resection of inferior cava vein sarcomas; re-implantation of the left renal vein being not mandatory if rich collateral circulation is present.

Neoadjuvant intraperitoneal chemotherapy for advanced stage gastric cancer (Review).

Gastric cancer remains one of the most lethal malignancies especially when diagnosed in advanced stages of the disease; most often patients diagnosed later during the progression of their disease will present a certain degree of peritoneal contamination such as positive peritoneal cytology or peritoneal metastatic nodules. In such cases most often they then progress to peritoneal carcinomatosis and succumb to the disease within one year. In order to increase the lifespan in such cases multiple therapeutic strategies have been proposed such as radical surgery and intraperitoneal heated chemotherapy or direct intraperitoneal chemotherapy followed by radical surgery. To date, the benefits of intraperitoneal heated chemotherapy at the time of resection have been widely investigated; however the method is still associated with increased rates of perioperative complications. Therefore, attention was focused on investigating the benefits of such procedures as neoadjuvant therapies followed by radical surgery. The aim of the present review was to examine the most efficient therapeutic strategies in advanced-stage gastric cancer such as neoadjuvant laparoscopic heated intraperitoneal chemotherapy, perioperative heated intraperitoneal chemotherapy and neoadjuvant systemic and peritoneal chemotherapy.

Distal Pancreatectomy With Celiac Axis Resection for Locally Advanced Pancreatic Body Cancer - A Case Report and Literature Review.

BACKGROUND: Locally advanced pancreatic cancer invading the surrounding vascular structures has long been considered as unresectable and, therefore, patients were usually submitted to palliative chemotherapy. CASE REPORT: We present the case of a 44-year-old male investigated for weight loss and abdominal pain and diagnosed with a locally advanced pancreatic tumor invading the celiac axis. An endoscopic ultrasound was performed and a biopsy was retrieved demonstrating the presence of a moderately differentiated pancreatic adenocarcinoma. After discussing with the patient the risks and the benefits of performing an extended surgical procedure, the patient consented to distal pancreatectomy en bloc with celiac axis resection. Postoperatively, the patient was submitted to low-molecular-weight heparin therapy for 3 weeks followed by oral anticoagulant for 2 months. Histopathological studies confirmed the presence of a moderately differentiated pancreatic adenocarcinoma invading the celiac axis and described negative resection margins. CONCLUSION: Although celiac axis invasion has been considered for a long period of time as a sign of unresectable disease due to the high rates of perioperative complications, it seems that in selected cases, surgery can be safely performed with curative intent, especially if negative resection margins are achieved.

A Rare Thymic Tumor - Lipofibroadenoma - Always a Postoperative Surprise.

BACKGROUND/AIM: Thymic lipofibroadenoma is a benign growth of unknown etiology extremely rarely described in the literature, morphologically resembling lipofibroadenoma of the breast. The diagnosis is usually a postoperative surprise and is made by the anatomopathologist. Surgical resection is curative. CASE REPORT: The presented case is the first reported in a woman, to date. The patient was successfully submitted to surgery and complete resection of the giant intrathoracic tumor was performed. The histopathological and immunohistochemical studies came to demonstrated the presence of a thymic lipofibroadenoma while the postoperative outcomes were favorable. CONCLUSION: In cases presenting large intrathoracic tumors complete resection is able to provide a significant improvement of the general condition of the patient, as well as a chance for cure.

Superior Mesenteric Vein Resection Followed by Porto-Jejunal Anastomosis During Pancreatoduodenectomy for Borderline Resectable Pancreatic Cancer - A Case Report and Literature Review.

BACKGROUND/AIM: Pancreatic cancer represents the most lethal abdominal malignancy, the only chance for achieving an improvement in terms of survival being represented by radical surgery. Although it has been considered that venous invasion represents a contraindication for resection, recently it has been demonstrated that in regards to overall survival after radical resection, it is similar to the one reported after standard pancreatoduodenectomy. CASE REPORT: A 53-year-old patient with no significant medical past was diagnosed with a borderline resectable pancreatic adenocarcinoma invading the superior mesenteric vein. The patient was submitted to pancreatoduodenectomy en bloc with superior mesenteric vein resection; the two jejunal veins were further anastomosed to the remnant portal vein. The postoperative outcome was favorable; the patient was discharged in the 10th postoperative day. CONCLUSION: Although technically more demanding, pancreatoduodenectomy en bloc with superior mesenteric vein resection and jejunal portal anastomosis is feasible and might offer a chance for long-term survival in borderline pancreatic head carcinoma invading the superior mesenteric vein.

Extended Venous Resections for Borderline Resectable Pancreatic Head Adenocarcinoma-A Retrospective Studies of Nine Cases.

BACKGROUND: pancreatic cancer is one of the most lethal malignancies and a leading cause of cancer-related death worldwide. The only chance to improve the long-term outcomes of patients with pancreatic cancer is surgery with radical intent. METHODS: in the present paper, we aim to describe a case series of 9 patients submitted to radical surgery for borderline resectable pancreatic cancer. RESULTS: in all cases, negative resection margins were achieved. The types of venous resection consisted of tangential portal vein resection in four cases, circumferential portal vein resection with direct reanastomosis in one case and circumferential resection with graft placement in another four cases; postoperatively, one patient developed a vascular surgery-related complication consisting of graft thrombosis and thus necessitated prolonged anticoagulant therapy. CONCLUSIONS: extended venous resections can be a safe and efficient way to maximize the benefits of radical surgery in locally advanced, borderline resectable pancreatic cancer.

Transcervical Mediastinoscopic Closure of Left-Sided Postpneumonectomy Bronchial Stump Fistula.

INTRODUCTION: This article presents a series of patients on which the transcervical approach was used to close a left-sided postpneumonectomy fistula. MATERIALS AND METHODS: The series comprises nine patients with a left pneumonectomy performed for a tuberculosis-related suppurative disease in five cases and for lung cancer in the remaining four. This procedure can be performed under certain conditions, the most important one being the length of the bronchial stump, which should be at least 1 cm, ideally 1.5 cm. The transcervical stump closure was successfully achieved in all patients, having been more technically demanding in cancer cases with previous lymphadenectomy. The postpneumonectomy infected cavity was subsequently treated. RESULTS: The follow-up continued for at least 1 year; one individual from the cancer patients group died from an uncontrolled sepsis during the postoperative period, another one died 17 months later from metastatic cancer and two of them are alive, with no signs of neoplastic or infectious relapse 15 and 37 months, respectively, after the cervical procedure. One patient from the suppurative disease group had a relapse of the fistula 2 months after surgery, requiring additional surgical procedures to deal with this issue; all the other patients are alive, with no signs of recurrence. CONCLUSIONS: The transcervical approach is a very suitable maneuver in selected patients with a bronchial stump at least 1 cm long, ideally 1.5 cm.

Anesthetic considerations for tracheobronchial resection in oncologic surgery.

PURPOSE OF REVIEW: Anesthesia for the resection and reconstruction of the tracheobronchial tree for neoplastic disease is challenging, both from surgical as well as anesthetic points of view. There are no published recommendations or guidelines addressing anesthetic and airway management dilemmas that arise during these surgical interventions. This review presents key aspects of preoperative imaging evaluation, surgical planning, as well as anesthesia and airway management during these complex cases. RECENT FINDINGS: Newly published articles highlight both the surgical and anesthetic challenges encountered during tracheobronchial resections and emphasize the importance of creating specialized, high-volume centers for good patient outcomes. Of great importance is the development of a preoperative joint anesthetic-surgical plan which includes a patient-specific airway management strategy. This review presents newer and less commonly employed anesthetic management strategies which have been recently described in the literature to allow expansion of care to patients who were previously deemed too high risk for surgery. SUMMARY: With advances in technology, the use of classical ventilation methods in conjunction with newer alternatives, such as extracorporeal membrane oxygenation, creates the premise for a more individualized, safer and controlled approach to tracheobronchial resections for oncologic purposes.

Post-Pneumonectomy ARDS and Ogilvie Syndrome - A Case Report.

INTRODUCTION: The Acute Respiratory Distress Syndrome (ARDS) is a severe hypoxemic acute lung injury that may complicate lung resections. Reported mortality is very high, up to 50%. This report covers an ARDS case occurring post left pneumonectomy, with a favorable outcome, despite association with an acute colonic pseudo-obstruction syndrome (Ogilvie syndrome) that required abdominal surgery for decompression. CASE REPORT: A 60-year old Caucasian male, diagnosed with a stage IIIA left lung tumor underwent a left pneumonectomy. On the second postoperative day, the patient developed ARDS, requiring ventilatory support. Two days later, as the multiple organ dysfunction worsened, a bowel obstruction occurred. With an acute colonic pseudo-obstruction diagnosis, the decision was to perform laparotomy and a temporary cecostomy. A subsequent improvement in the respiratory parameters and vital functions resulted in weaning from ventilator 8 days after the onset of the ARDS and transfer to the surgery ward 14 days after pneumonectomy.

Comparative Study of Early Postoperative Complications: Thoracic Anastomosis vs Cervical Anastomosis - in Esophageal Replacement with Gastric Graft.

Gastric pull-up is the most commonly used procedure for esophageal replacement in both malignant and benign conditions. In our article we compare the differences in mortality and morbidity between thoracic anastomosis and cervical anastomosis during gastric pull-up. The study group comprised of 126 patients - 58 patients (56%) with cervical anastomosis and 68 patients (64%) with thoracic anastomosis. The overall mortality in the study group was 5.55% (7 patients), while the overall morbidity was higher at 28%. There were no significant differences between the two subgroups regarding mortality and morbidity, although the rate of anastomotic leakage was higher in the cervical subgroup (13.8% vs 1.5%). We recommend performing thoracic anastomosis during gastric pull-up whenever the location of the lesion allows it, since the procedure is safe, relatively easy to master and it shortens operating time by excluding the cervical approach.

Postintubation Tracheoesophageal Fistula - Diagnosis, Treatment and Prognosis.

Introduction: Postintubation tracheoesophageal fistula is a severe complication occurring under certain conditions in patients that require prolonged mechanical ventilation. MATERIAL AND METHODS: This article focuses on a sample of 11 patients with postintubation tracheoesophageal fistula, operated in our department between 2005 and 2015. The anterior approach with tracheal resection was performed in 10 of these patients, while an atypical surgical technique was preferred in a case involving a large-sized fistula. Three of these patients were subject to surgery while still on the ventilator, in order to help weaning them from mechanical ventilation. Two patients were operated following a relapse of the fistula, after attempts of closing it in other surgical units. Results: Two patients (of those who were still on mechanical ventilation) died from intubation-related complications that persisted after tracheal resection (anastomotic dehiscence with mediastinitis and tracheoarterial fistula in the brachiocephalic arterial trunk). The nine remaining patients improved, with their airways restored and having regained normal deglutition. Conclusions: The surgical approach of this pathology is successful in surgical units that are specialised in tracheal and oesophageal surgery. Adequately timing the surgery is crucial for a good outcome.

Surgery and pleuro-pulmonary tuberculosis: a scientific literature review.

Tuberculosis (TB) is still a major public health concern, mostly affecting resource-constrained settings and marginalized populations. The fight against the disease is hindered by the growing emergence of drug-resistant forms whose management can be rather challenging. Surgery may play an important role to support diagnosis and treatment of the most complex cases and improve their therapeutic outcome. We conducted a non-systematic review of the literature based on relevant keywords through PubMed database. Papers in English and Russian were included. The search was focused on five main areas of intervention as follows: (I) diagnosis of complicated cases; (II) elimination of contagious persisting cavities, despite appropriate chemotherapy; (III) treatment of destroyed lung; (V) resection of tuberculomas; (VI) treatment of tuberculous pleural empyema. Although specific practical guidelines concerning surgical indications and approaches are currently unavailable, a summary of the evidence emerged from the scientific literature was elaborated to help the clinician in the management of severely compromised TB patients. The decision to proceed to surgery is usually individualized and a careful assessment of the patient's risk profile is always recommended before performing any procedure in addition to appropriate chemotherapy.

Pulmonary metastasectomy--general issues.

Pulmonary metastasectomy has been widely accepted by thoracic surgeons and is applied to the treatment of a variety of histologies, but the evidence that the patient may benefit from lung metastasectomy is not yet elucidated and the best way of integrating oncologic therapies (induction or adjuvant chemotherapy or radiotherapy) with surgical resection are still unknown. When there is no good clinical alternative, the resection of pulmonary metastases can give some patients long-lasting disease free intervals. Patients should be carefully selected on the basis of clinical staging with defined prognostic indicators. In order to obtain suitable results the management of these patients should be based on a multidisciplinary team decision.

Tissue prints for the rapid diagnosis of malignancy in lung cancer.

UNLABELLED: Rapid diagnosis of malignancy during oncological surgery is crucial for making decisions related to the extension of the resection. The tissue prints, used initially for plant biology but also for prostate or breast cancer diagnosis, might be useful as a rapid cytological diagnosis. MATERIALS AND METHODS: Tissue prints were done from freshly sectioned excised tissue fragments in patients operated between March 2010 and February 2012 in the Department of Surgery for cancer or benign lesions. Tissue prints were examined by a cytologist and considered as malignant or benign. Same fragments were then processed in the pathology laboratory using the typical paraffin-embedding method. All slides were examined by the same pathologist and considered the golden standard for malignancy and histological type. RESULTS: Three hundred and eleven fragments were examined, obtained from lung masses, lymph nodes, pleura and mediastinal masses, pathology showed 208 malignant and 103 benign. Tissue prints identified 227 malignant and 84 benign. For identifying malignancy, tissue prints had a sensibility of 0.91, specificity 0.64. Positive predictive value was 0.86 and negative predictive value 0.78. For lymph nodes, the specificity was better. In lymphomas and adenocarcinomas, tissue prints identified also the histology type in most cases. CONCLUSIONS: Tissue prints are rapid, easy to perform, cheap, with high sensibility but specificity lower than literature data on frozen sections. This might be improved by a better selection of cases where tissue prints are used for rapid diagnosis.
