Robotic-assisted minimally invasive esophagectomy - our first experience.

Introduction: Minimally invasive esophagectomy is associated with lower postoperative morbidity and better quality of life compared to open esophagectomy in patients with comparable oncological outcomes. Robotic-assisted surgery represents the next step in the development of mini- mally invasive surgery. We aim to present the results of a pilot cohort of patients undergoing robotic-assisted minimally invasive esophagectomy (RAMIE).

The TRAIL in the Treatment of Human Cancer: An Update on Clinical Trials.

TRAIL (tumor-necrosis factor related apoptosis-inducing ligand, CD253) and its death receptors TRAIL-R1 and TRAIL-R2 selectively trigger the apoptotic cell death in tumor cells. For that reason, TRAIL has been extensively studied as a target of cancer therapy. In spite of the promising preclinical observations, the TRAIL-based therapies in humans have certain limitations.

Prognostic role of early 18-FDG PET/CT during neoadjuvant chemotherapy for resectable adenocarcinoma of the esophagus and esophagogastric junction.

We prospectively investigated whether metabolic response assessed by 18F-fluorodeoxyglucose positron emission tomography combined with computed tomography (PET/CT) early in the course of neoadjuvant chemotherapy is predictive of survival in patients with adenocarcinoma of the esophagus and esophagogastric junction. PET/CT was performed before and in the third week after the initiation of the first cycle of neoadjuvant chemotherapy, which consisted of epirubicin, cisplatin, and 5-fluorouracil or capecitabine. The metabolic response was defined as a relative decrease in the peak standardized uptake value (SUL) of the tumor by ≥35% or total lesion glycolysis (TLG) by ≥66%.

Treatment of anastomotic leak after Ivor Lewis esophagectomy.

Introduction: Anastomotic leak (AL) is one of the most serious surgical complications after esophagectomy. Endoscopic, radiological and surgical methods are used in the treatment of AL. The aim of this study was to retrospectively evaluate our therapeutic procedures and results of AL treatment after Ivor Lewis esophagectomy (ILE).

Tumoral and paratumoral NK cells and CD8 T cells of esophageal carcinoma patients express high levels of CD47.

In a limited number of human malignancies, anti-CD47 therapy leads to the rapid clearance of tumor cells by macrophages. In esophageal squamous cell carcinoma, anti-CD47 treatment has shown promising results in vitro. However, the CD47 expression pattern in tumor-infiltrating lymphocytes (TILs), which are associated with prolonged overall survival and serve as a positive prognostic factor, is largely unknown.

The paratumoral immune cell signature reveals the potential for the implementation of immunotherapy in esophageal carcinoma patients.

Purpose: Esophageal cancer (EC) is one of the most lethal gastrointestinal malignancies. Immunotherapy is a promising treatment modality for this disease. However, broader implementation of EC immunotherapy has been discouraged because of insufficient understanding of tumor interactions with the immune system.

[ F]Fluorodeoxyglucose PET/CT and prediction of histopathological response to neoadjuvant chemotherapy for adenocarcinoma of the oesophagus and oesophagogastric junction.

Background: The aim of this prospective study was to assess whether [ F]fluorodeoxyglucose PET can be used to predict histopathological response early in the course of neoadjuvant chemotherapy in patients with adenocarcinoma of the oesophagus and oesophagogastric junction.

Methods: Following the PET response criteria in solid tumours (PERCIST 1.0) as a standardized method for semiquantitative assessment of metabolic response, FDG-PET/CT was performed before (PET1) and after (PET2) initiation of the first cycle of chemotherapy.

Anastomotic leak and stricture after hand-sewn versus linear-stapled intrathoracic oesophagogastric anastomosis: single-centre analysis of 415 oesophagectomies.

Objectives: There seems to be a decreased anastomotic leak rate and a late stricture formation after linear-stapled (LS) cervical oesophagogastric anastomosis compared with hand-sewn (HS) technique. The aim of our study was to compare the surgical outcomes of intrathoracic side-to-side LS and end-to-end HS anastomosis after transthoracic oesophagectomy.

Methods: We conducted a retrospective review of all patients undergoing Ivor Lewis oesophagectomy with LS or HS anastomosis for neoplasia at our institution from 2005 to 2012.

[Intramural haematoma of the oesophagus - a case report and literature review].

Intramural hematoma of the oesophagus is a rare diagnosis presenting with retrosternal pain, dysphagia and haematemesis. It is caused by barotrauma or direct injury to the esophagus, or it may occur spontaneously without apparent cause, which is more common in patients taking antiplatelet or anticoagulant medications. In most cases, treatment is conservative.

The effect of postoperative pain treatment on the incidence of anastomotic insufficiency after rectal and rectosigmoideal surgery.

The aim of prospective study was to evaluate the pain relief in the postoperative period and consumption of opioid and non-opioid analgesics as a risk factor of the anastomotic insufficiency after rectal and rectosigmoideal resection for carcinoma. Anastomotic insufficiency is one of the most feared and life threatening early complications. No articles about the effect of the response to opioid therapy in the postoperative period on the risk of this major clinical problem have been published.

[Are antibiotics necessary in the treatment of uncomplicated diverticulitis?].

Introduction: This paper deals with the results of recently published studies on the importance of the use of antibiotics in the treatment of uncomplicated diverticulitis. It is based on the articles available in the Medline database.

Conclusion: The prevalence of diverticulosis in the developed countries of the Western world is increasing and, along with it, the costs of treatment of diverticulitis.

[Esophageal perforation].

Objective: Evaluation of patients with acute esophageal perforations with single institution experience.

Material And Methods: The authors evaluate the set of 64 consecutive patients with esophageal perforation treated in our department between January 2000 and December 2010. In all patients were before decision making performed CT scans and X-ray examination with contrast agent administration.
