[Gender medicine in diseases of the upper gastrointestinal tract].

Benign and malignant diseases of the upper gastrointestinal tract show gender-specific differences. The frequent gastroesophageal reflux disease is a prime example: men have an erosive reflux disease more often than women and are also younger at the time of onset. The rate of progression to a metaplastic Barrett's esophagus is also higher in men.

International External Validation of Risk Prediction Model of 90-Day Mortality after Gastrectomy for Cancer Using Machine Learning.

Background: Radical gastrectomy remains the main treatment for gastric cancer, despite its high mortality. A clinical predictive model of 90-day mortality (90DM) risk after gastric cancer surgery based on the Spanish EURECCA registry database was developed using a matching learning algorithm. We performed an external validation of this model based on data from an international multicenter cohort of patients.

Premature mortality for patients after completely resected early adenocarcinoma of the esophagus or stomach.

Objective: To establish the life expectancy burden of esophago-gastric cancer by analyzing years of life lost (YLL) for a Western patient population after treatment of early esophageal (EAC) or early gastric (GAC) adenocarcinoma.

Background: For patients with early EAC or GAC, the short-term prognosis after surgical resection is very good. Little data is available regarding long-term prognosis when compared to the general population.

[Esophageal cancer: standards and innovations in multidisciplinary treatment].

Esophageal cancer is a severe disease that requires a combined therapeutic approach to improve the prognosis. Once the initial assessment is completed, the patient's case should be discussed in a multidisciplinary conference in a specialized center to decide on an appropriate therapeutic strategy taking into account the stage of the disease and the patient's general condition. Several advances in treatment, both from a surgical technique standpoint, with the advent of minimally invasive and robotic surgery, and from a medical perspective, with the use of immunotherapy under certain conditions, have dramatically improved mortality rates.

Assessment of predictors of early postoperative complications after primary robotically assisted Roux-en-Y gastric bypass: a multicenter, retrospective cohort study.

Background: Robotic Roux-en-Y gastric bypass (RRYGB) is performed in an increasing number of bariatric centers worldwide. Previous studies have identified a number of demographic and clinical variables as predictors of postoperative complications after laparoscopic Roux-en-Y gastric bypass (LRYGB). Some authors have suggested better early postoperative outcomes after RRYGB compared to LRYGB.

Outcome of endoscopic vacuum therapy for duodenal perforation.

Background: Duodenal defects are complex clinical situations, and their management is challenging and associated with high mortality. Besides surgery, endoscopic treatment options exist, but the size and location of the perforation can limit their application. We present a retrospective study, demonstrating a successful application of endoscopic vacuum therapy (EVT) for duodenal leaks.

Implementation and validation of a competency assessment tool for laparoscopic cholecystectomy.

Background: Achieving proficiency in a surgical procedure is a milestone in the career of a trainee. We introduced a competency assessment tool for laparoscopic cholecystectomy in our residency program. Our aim was to assess the inter-rater reliability of this tool.

[Chemotherapy and Radio-Chemotherapy of Locally Advanced Esophageal Cancer].

Chemotherapy and Radio-Chemotherapy of Locally Advanced Esophageal Cancer Surgical resection alone of locally advanced esophageal carcinoma leads to long-term survival in only about 30% of cases. The multimodal strategy for locally advanced tumors, especially neoadjuvant radiochemotherapy and chemotherapy, has significantly improved the long-term prognosis. Multimodal therapy concepts have been developed which improve overall survival.

[Modern Multimodal Concepts for Advanced and Metastatic Esophageal Cancer].

Modern Multimodal Concepts for Advanced and Metastatic Esophageal Cancer In case of locally advanced esophageal carcinoma, the clear recommendation for multimodal therapy has been established in the guidelines. This also applies to systemic therapy in the palliative, metastatic situation. Against the background of increasing experience with multimodal concepts and a parallel trend towards more and more personalized tumor therapy, therapy options that go beyond this are increasingly being used.

Multimodal treatment in oligometastatic gastric cancer.

Gastric cancer is generally diagnosed at an advanced stage, especially in countries without screening programs. Previously, the metastatic stage was synonymous with palliative management, and surgical indications were only for symptomatic relief. However, this therapeutic option is associated with poor prognosis.

Predictive Value of Preoperative Endoscopic Ultrasound (EUS) After Neoadjuvant Chemotherapy in Locally Advanced Esophagogastric Cancer - Data From a Randomized German Phase II Trial.

Purpose: The role of EUS before or after neoadjuvant chemotherapy (nCTX) in advanced esophagogastric cancer (EGC) is still unclear. The phase II NEOPECX trial evaluated perioperative chemotherapy with or without panitumumab in this setting. The aim of this sub-study was to investigate the prognostic value of EUS-guided preoperative staging before and after nCTX.

Preventive HIPEC in combination with perioperative FLOT versus FLOT alone for resectable diffuse type gastric and gastroesophageal junction type II/III adenocarcinoma - the phase III "PREVENT"- (FLOT9) trial of the AIO /CAOGI /ACO.

Background: The main reason for treatment failure after curative surgical resection of gastric cancer is intra-abdominal spread, with 40-50% peritoneal seeding as primary localization of recurrence. Peritoneal relapse is seen in 60-70% of tumors of diffuse type, compared to only 20-30% of intestinal type. Hyperthermic IntraPEritoneal Chemoperfusion (HIPEC) is an increasingly used therapy method for patients with peritoneal metastases.

[Treatment options for oligometastatic gastric cancer].

Background: At the time of diagnosis of gastric cancer approximately one third of patients already have metastases. It is important to differentiate between oligometastasis and the diffuse metastatic situation. For the first time the definition of oligometastasis has been integrated into the German S3 guidelines.

Current surgical treatment standards for esophageal and esophagogastric junction cancer.

A number of different surgical techniques for the treatment of cancer of the esophagus and the esophagogastric junction have been proposed. Guidelines generally recommend a transthoracic approach for esophageal cancer, including Siewert type I tumors. In tumors of the proximal esophageal third, transthoracic esophagectomy may be extended to a three-field approach, including resection of cervical lymph nodes.

[Esophageal and esophago-gastric junction cancer : management and multimodal treatment].

Esophageal cancer remains an oncological burden with a low survival rate. Multidisciplinary management is essential to offer an adjusted treatment to the patient general condition and the tumor stage. New minimally invasive surgical treatments help to reduce the surgical trauma and improve post-operative patient recovery.

Minimal length of proximal resection margin in adenocarcinoma of the esophagogastric junction: a systematic review of the literature.

The minimal length of proximal margin (PM) in esophagogastric junction cancer has not been established yet and its impact on patient survival remains unclear. Pubmed, Embase and Scopus databases were searched for "adenocarcinoma of the esophagogastric junction", "adenocarcinoma of the gastroesophageal junction" and "cardia cancer", each combined with "proximal margin". English written studies that specified PM length in AEG were included.

Pressurized intraperitoneal aerosol chemotherapy (PIPAC) in combination with standard of care chemotherapy in primarily untreated chemo naïve upper gi-adenocarcinomas with peritoneal seeding - a phase II/III trial of the AIO/CAOGI/ACO.

Background: Peritoneal metastasis is a common and dismal evolution of several gastrointestinal (GI) tumors, including gastric, colorectal, hepatobiliary, pancreatic, and other cancers. The therapy of peritoneal metastasis is largely palliative; with the aim of prolonging life and preserving its quality. In the meantime, a significant pharmacological advantage of intraperitoneal chemotherapy was documented in the preclinical model, and numerous clinical studies have delivered promising clinical results.

Neoadjuvant chemoradiation for patients with advanced oesophageal cancer - which response grading system best impacts prognostic discrimination?

Aims: Neoadjuvant chemoradiation reduces tumour volume and improves the R0 resection rate, followed by extended survival for patients with advanced oesophageal cancer. The degree of tumour regression has high prognostic relevance. To date, there is still no generally accepted tumour regression grading system.

Multimodal treatment in locally advanced gastric cancer.

According to the data of the GLOBOCAN-network of the World Health Organization, there were 952,000 (6.8% of the total) new cases of gastric cancer in 2012, making it the fifth most common malignancy in the world. It represents a substantive change since the very first estimates in 1975 when stomach cancer was the most common neoplasm.

The presence of an asymptomatic aberrant right subclavian artery: A potential risk factor in esophageal surgery?

Bleeding of an aberrant right subclavian artery following transthoracic en bloc esophagectomy and intrathoracic gastric reconstruction is a rare but severe complication in esophageal surgery. Preoperative diagnosis can be achieved by computed tomography or magnetic resonance angiography (MRA). Various treatment options are available; thus, the treatment can be challenging and should be adjusted to the severity of the symptoms.

[Foreign-Body Ingestion: A Rare Cause of Abdominal Pain].

History And Findings Upon Admission: A 50-year-old man presented at the emergency unit with abdominal pain in the right lower quadrant and dysuria. He described an increase in pain during micturition.

Examinations: After multiple examinations (CT-scan, MR-scan, ileocolonoscopy) were performed to no avail, a toothpick was detected in the terminal ileum during an ultrasound scan of the small intestine.
