Primary Synovial Sarcoma of the Kidney: Diagnostic Approach and Therapeutic Modalities for a Rare Nosological Entity.

Synovial sarcoma (SS) is a rare mesenchymal entity that represents 5-10% among soft tissue sarcomas (STS). Primary renal synovial sarcoma (PRSS) is an uncommon, rapidly growing tumor, with potential metastatic dissemination. The main prognostic factors of PRSS include tumor size and histologic grade, while translocation t (X; 18) (p11.

Identifying the role of preoperative oral/dental health care in post-esophagectomy pulmonary complications: a systematic review and meta-analysis.

Esophageal surgery has traditionally been associated with high morbidity rates. Despite the recent advances in the field of minimally invasive surgery and the introduction of enhanced recovery after surgery (ERAS) protocols, post-esophagectomy morbidity, especially that attributed to the respiratory system, remains a concern. In that respect, preoperative intensification of oral care or introduction of structured oral/dental hygiene regimens may lead to tangible postoperative benefits associated with reduced morbidity (respiratory or otherwise) and length of hospital stay.

Objective: To evaluate niraparib safety profile, as maintenance therapy, in women with platinum-sensitive EOC.

Esophageal cancer surgery in Greece during the era of the financial crisis.

The aim of this study is to describe outcomes of esophageal cancer surgery in a quaternary upper gastrointestinal (GI) center in Athens during the era of the Greek financial crisis. We performed a retrospective analysis of patients that underwent esophagectomy for esophageal or gastroesophageal junction (GEJ) cancer at an upper GI unit of the University of Athens, during the period January 2004-June 2019. Time-to-event analyses were performed to explore trends in survival and recurrence.

Gastric ischemic preconditioning may reduce the incidence and severity of anastomotic leakage after οesophagectomy: a systematic review and meta-analysis.

Anastomotic leakage after esophagectomy is a severe and life-threatening complication. Gastric ischemic preconditioning is a strategy for the improvement of anastomotic healing. Aim of this systematic review and meta-analysis is to investigate the impact of gastric ischemic preconditioning on postoperative morbidity.

Glycoprotein non-metastatic melanoma B expression after hepatic ischemia reperfusion and the effect of silibinin.

Background: Glycoprotein non-metastatic melanoma B (GPNMB) is a transmembrane glycoprotein with various roles in inflammation regulation, tissue remodeling and oncogenesis. Clinical situations implicating alterations in its expression include ischemic injury, cirrhosis and fatty liver disease amongst other. We examine its expression in hepatic and renal tissue following hepatic ischemia-reperfusion (I/R) in a rat model, with and without intravenous silibinin administration, as a silibinin-hydroxypropyl-β-cyclodextrin lyophilized complex (SLB-HP-β-CD).

Pseudoachalasia: a systematic review of the literature.

Pseudoachalasia, also known as secondary achalasia, is a clinical condition mimicking idiopathic achalasia but most commonly caused by malignant tumors of gastroesophageal junction (GEJ). Our aim was to systematically review and present all available data on demographics, clinical features, and diagnostic modalities involved in patients with pseudoachalasia. A systematic search of literature published during the period 1978-2019 was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (end-of-search date: June 25th, 2019).

Dealing With Burn Patients in War Zones.

Objective: Treating burn patients in the battlefield is one of the biggest challenges that military doctors and medical personnel can face. Wound patterns have been changed over time due to the introduction of new weapons, and many different aspects play a major role in the management of those burns nowadays. There is a potential gap in care of burn patients in war zones.

New insights into irritable bowel syndrome: from pathophysiology to treatment.

Irritable bowel syndrome (IBS) is the most common reason to visit a gastroenterologist. IBS was believed to be a functional disease, but many possible pathophysiologic mechanisms can now explain the symptoms. IBS patients are classified into subtypes according to their predominant bowel habit, based on the Rome IV criteria.

Staged esophagectomy: surgical legacy or a bailout option?

Staged esophagectomy was developed in the mid-twentieth century in an attempt to reduce high rates of postoperative morbidity and mortality. Nowadays, the operation has almost been abandoned due to its significant disadvantages, especially the need for multiple surgeries, inability of patients to feed between operations, and morbidity of esophageal stoma. However, staged esophagectomy is still occasionally useful for very high-risk patients and in particular cases, for example multiple cancers of the aerodigestive tract and emergent esophagectomy.

Hybrid Laparoscopic and Endoscopic Partial Gastrectomy for Ulcerated GIST: Surgical Technique with Video.

Introduction: Gastrointestinal stromal tumors of the gastric cardia pose several technical difficulties to their resection because they are difficult to access, and they must be removed respecting oncological principles, and due to their proximity to the gastroesophageal junction, excessive removal of gastric tissue may cause deformation with gastric dysfunction, or gastroesophageal reflux.

Method: Hybrid laparoscopic endoscopic partial gastrectomy is a technique that avoids these problems making use of three principles. First the tumor is pinpointed, marked, and resected under combined laparoscopic and endoscopic control to assure that it is completely resected without compromising the structure of the gastroesophageal junction.

Synchronous resection of esophageal cancer and other organ malignancies: A systematic review.

Background: Neoplasms arising in the esophagus may coexist with other solid organ or gastrointestinal tract neoplasms in 6% to 15% of patients. Resection of both tumors synchronously or in a staged procedure provides the best chances for long-term survival. Synchronous resection of both esophageal and second primary malignancy may be feasible in a subset of patients; however, literature on this topic remains rather scarce.

The profile of patients receiving public and private surgical services in Greece during the economic crisis: a comparative study.

Background: International experience has shown that deterioration of healthcare services is a common consequence of socio-economic crises. Exact mechanism of this deterioration varies with respect to particularities of each healthcare system, government and administrative policies and local epidemiological conditions. The aim of the present study was to evaluate the effect of Greek economic crisis on the profile and the satisfaction rates of patients seeking surgical services in public and private hospitals.

Arc of Bühler: the surgical significance of a rare anatomical variation.

Purpose: The arc of Bühler, an anastomotic vessel between celiac artery and superior mesenteric artery, is a rare anatomic variation. Various radiologic and surgical procedures can be affected by its existence. We aim to review all available information and identify possible clinical implications.

Collision Tumors of the Gastrointestinal Tract: A Systematic Review of the Literature.

Background/aim: Collision tumors are rare neoplasms which consist of two or more distinct neoplasms that develop adjacent to one another and coexist with no or minimal intermingling between them. Their diagnosis is often incidental and their behavior remains widely unknown. Several theories have been proposed regarding their pathogenesis.

Favoring D-Lymphadenectomy in Gastric Cancer.

The role of extended lymphadenectomy in the surgical treatment of gastric cancer has been debated for many years. So far six prospective randomized trials and a number of meta-analyses comparing D- to D-lymphadenectomy in open surgery have been published with contradicting results. The possible oncologic benefit of radical lymphadenectomy has been blurred by a number of reasons.
