Impact of perioperative chemotherapy on postoperative morbidity after gastrectomy for gastric cancer.

Introduction: The use of perioperative chemotherapy (CT) in patients with advanced gastric carcinoma increases their overall survival. This therapy may also increase the number of patients with R0 resection. Potential drawbacks of this therapy, besides its toxicity, include increased surgical morbidity.

Complete pathological response (pCR) in gastroesophageal cancer: Correlation with metabolic response.

Purpose: Neoadjuvant chemoradiotherapy (nCRT) followed by surgery in patients with resectable esophageal or esophagogastric junctional (GEJ) (Siewert I) cancer is associated with long term overall survival benefits. Up to one third of all patients submitted to nCRT present pathological complete response (pCR). F-fluorodeoxyglucose positron emission tomography with CT (F-FDG PET-CT) is an important tool for assessing treatment response.

Oesophageal GIST.

Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract. Oesophageal GISTs are extremely uncommon, accounting for 0.7% of all GISTs, and their management is surrounded by some debate.

Transitioning from anatomic landmarks to ultrasound guided central venous catheterizations: guidelines applied to clinical practice.

Introduction: Centrally inserted central catheter (CICC) insertion is a commonly performed procedure that may give rise to different complications. Despite the suggestion of guidelines to use ultrasound guidance (USG) for vascular access, not all centers use it systematically. The aim of this study is to illustrate the experience with ultrasound in CICC placement at a high-volume oncological center, in a country where the landmark technique is standard.

Stents in patients with esophageal cancer before chemoradiotherapy: high risk of complications and no impact on the nutritional status.

Preoperative chemoradiotherapy is the standard of care for locally advanced esophageal cancer, causing persistent deterioration in the nutritional status. We performed a prospective study to evaluate the safety and efficacy of esophageal double-covered self-expandable metal stents in patients with esophageal cancer before chemoradiotherapy. The nutritional status and dysphagia were prospectively recorded.

Enteric repair in aortoduodenal fistulas: a forgotten but often lethal player.

Background: An aortoenteric fistula is an abnormal communication between the aorta and the bowel lumen. It is usually caused by previous aortic surgery and involves the duodenum (ADF) in most cases. The treatment of this high-mortality condition is based on the correction of enteric and vascular defects.
