Prognostic insights after surgery for advances in understanding signet ring cell gastric cancer: a machine learning approach.

Background: Signet ring cell (SRC) gastric carcinoma is traditionally associated with a poor prognosis. However, the literature has presented contradictory results. Linear models are the standard statistical tools typically used to study these conditions.

Pilot Trial on Ischemic Conditioning of the Gastric Conduit in Esophageal Cancer: Feasibility and Impact on Anastomotic Leakage (TIGOAL-I).

Objective: To evaluate the feasibility, safety, and effectiveness of gastric conditioning using preoperative arterial embolization (PAE) before McKeown esophagectomy at a tertiary university hospital.

Background: Cervical anastomotic leakage (AL) is a common complication of esophagectomy. Limited clinical evidence suggests that gastric conditioning mitigates this risk.

Characteristics of gastrointestinal stromal tumors associated to other tumors: Características de los tumores del estroma gastrointestinal asociados a otras neoplasias.

Introduction: Our aim is to analyze the differences between sporadic gastrointestinal stromal tumors and those associated with other tumors.

Methods: Retrospective cohort study including patients with diagnosis of gastrointestinal stromal tumors operated at our center. Patients were divided into two groups, according to whether or not they had associated other tumors, both synchronously and metachronously.

Combined Treatment of an Aortoesophageal Fistula After Aortoplasty for Aortic Stenosis.

The aortoesophageal fistula secondary to the rupture of an aneurysm is a rare entity that usually has a fatal outcome. We present the case of a young patient with an aortoesophageal fistula secondary to a thoracic aortic aneurysm successfully treated with a combination of endoscopic and surgical techniques.
