[Comparison of outcome of rigid and self-expanding stents for palliation of malignant dysphagia].

Introduction: Between 1984 and 2019, 1005 rigid prostheses and 423 self-expanding stents were inserted for palliation of malignant esophageal stenosis.

Objective: The aim of this study was the comparison of the treatment results using the two types of prosthesis.

Method: Retrospective analysis has been performed comparing the characteristics and treatment results of the two patients groups referring to the technical success of the procedures, procedure-related complications, change in the quality of life, and survival time.

[Oesophagus stricture caused by late metastasis of breast cancer].

Oesophageal strictures due to mediastinal metastases from breast cancer mean a significant diagnostic and therapeutic challenge, since they are relatively rare, difficult to identify and detect. In our case, slowly progressive dysphagia developed 19 years after mastectomy. During dilatation of the stricture, which was thought benign first, the oesophagus was perforated.

In situ lymphoma imaging in a spontaneous mouse model using the Cerenkov Luminescence of F-18 and Ga-67 isotopes.

Cerenkov luminescence imaging (CLI) is a promising approach to image-guided surgery and pathological sampling. It could offer additional advantages when combined to whole-body isotope tomographies. We aimed to obtain evidence of its applicability in lymphoma patho-diagnostics, thus we decided to investigate the radiodiagnostic potential of combined PET or SPECT/CLI in an experimental, novel spontaneous high-grade B-cell lymphoma mouse model (Bc.

[Reconstruction with hypopharyngo-gastrostomy after esophagus extirpation due to spontaneous esophageal perforation].

Despite the significant improvement in surgical and intensive care therapy, esophageal perforation is still a severe, life-threatening condition. As the underlying causes, the accompanying disorders, the localization and the extent of the inflammation vary, the surgeon may sometimes encounter unexpected situations. A 58-year-old female developed necrotizing mediastinitis due to esophageal perforation as the result of incarcerated thoracic hernia of the stomach, therefore, we had to perform esophagus extirpation and cervical esophagostomy.

[Cases of migration of swallowed foreign bodies from the gastrointestinal tract].

Migration of swallowed foreign bodies from the gastrointestinal tract is a rare phenomenon compared with the total number of ingestions. In the reported two cases, the serious septic condition indicated urgent surgical intervention. We found a piece of wire swallowed a few months earlier in the right lobe of the liver and the retroperitoneum in case one, and a piece of wire in the pericardium, which migrated from the stomach through the left lobe of the liver, in case two.

[Surgical excision of a giant schwannoma located in the posterior mediastinum and partially in the retroperitoneum].

A characteristics of mediastinal disorders is that the high anatomical density of vital structures in this region represents a challenge for diagnosis and surgical treatment. Space-occupying lesions can grow without causing overt manifestations - or can progress symptom-free - hence they can reach an extreme size by the time of surgery. A 58-year-old male patient was hospitalized for pleural effusion and an extensive, space-occupying mediastinal lesion, which had been causing respiratory symptoms for 15 years.

[Operative treatment of non-malignant esophageal perforations - a summary of our experiences].

Introduction: Despite significant development in surgical and intensive therapy, esophageal perforation is still a severe, life-threatening condition. Successful therapy depends on several clinical factors, available medical equipments, but most of all on the available expertise and experience.

Patients And Methods: We retrospectively evaluated patients' data operated at the 1st Department of Surgery at Semmelweis University between 2005 and 2017 due to esophageal perforation of non-malignant origin.

[Relationship of consequences of anastomotic insufficiency and bacterial flora of oral cavity in patients with esophageal and cardia cancer].

Introduction: In the course of anastomotic insufficiency following resection of esophageal cancers the bacterial compound of the esophageal substance has a remarkable, presumable role in the outcome of complications.

Aim: The purpose of this study is to compare the consequences of the anastomotic leak with the bacterial flora of patients' oral cavity.

Method: In this prospective study a total of 131 patients were investigated directly before the surgical intervention taking a bacterial sample.

Quantitative liver lesion volume determination by nanoparticle-based SPECT.

Purpose: The aim of this paper is to present a simple and quantitative data analysis method with a new potential in the application of liver single-photon emission computed tomography (SPECT) imaging. We have established quantitative SPECT/computed tomography (CT) in vivo imaging protocols for determination of liver tumor burden based on the known role of Kupffer cells in cancer of the liver.

Procedures: As it is also known that functional Kupffer cells accumulate particulate material contained in the arterial blood of liver supply, we used radiolabeled macro-aggregated albumin particles ([(99m)Tc]-MAA) injected intravenously to image liver disease.

Experience with stent implantation in malignant esophageal strictures: analysis of 1185 consecutive cases.

Purpose: The aim of this retrospective study was to analyze the experience in endoprosthesis implantation in cases of malignant esophageal strictures.

Methods: A total of 1185 consecutive patients underwent endoprosthesis implantation: through open surgery in 42 cases and by endoscopy in 1143 cases.

Results: Stent implantation was performed successfully in 61.

[Palliative management of malignant oesophageal strictures with endoprosthesis implantation -- 25 years experience].

Objectives: The aim of this study was to analyse the feasibility of the use of oesophageal endoprosthesis based on a large series of cases.

Methods: 2952 malignant oesophageal strictures managed between 1984 and 2009 were analysed. While surgical intubation was carried out in 42 patients, endoscopic implantation was feasible in 1143 cases.

[Surgical repair of postintubation esophago-tracheal fistulas: report of two cases surgically repaired].

Persistence of postintubation esophago-tracheal fistulas is a difficult therapeutic problem. Authors present and discuss two successfully operated cases. Surgical reconstruction was done via left lateral cervical approach, including dissection of the fistulous tract, closure of the defect on both sides by suture, exclusion of the esophagus with a linear stapler beyond a loop esophagostomy, separation the suture lines with interposing of omohioid muscle flap, and making a Pezzer-catheter splinted esophagostomy.

Characteristics of esophagorespiratory fistulas resulting from esophageal cancers: a single-center study on 243 cases in a 20-year period.

Background: Esophagorespiratory fistulas are serious complications of esophageal tumors. The main goal of this study was to reveal their characteristics.

Methods: In the period between 1984 and 2004, 243 fistulas were diagnosed among the 1993 patients with esophageal cancer.

Esophagorespiratory fistulas of tumorous origin. Non-operative management of 264 cases in a 20-year period.
