Digestiva (Spanish Society of Digestive Endoscopy) and the Sociedad Espanola de Anatomía Patológica (Spanish Society of Pathology), aims to establish recommendations for the screeningof gastric cancer (GC) in low incidence populations, such as the Spanish. To establish the quality of the evidence and the levels of recommendation, we used the methodology based on theGRADE system (Grading of Recommendations Assessment, Development and Evaluation). We obtained a consensus among experts using a Delphi method. The document evaluates screening in the general population, individuals with relatives with GC and subjects with GC precursor lesions (GCPL). The goal of the interventions should be to reduce GC-related mortality. We recommend the use of the OLGIM classification and to determine the intestinal metaplasia(IM) subtype in the evaluation of GCPL. We do not recommend establishing endoscopic massscreening for GC or H. pylori. However, the document strongly recommends treating H. pylori if the infection is detected, and investigation and treatment in individuals with a family history of GC or with GCPL. Meanwhile, we recommend against the use of serological tests to detect GCPL. Endoscopic screening is suggested only in individuals that meet familial GC criteria. As for individuals with GCPL, endoscopic surveillance is only suggested in extensive IM associated with additional risk factors (incomplete IM and/or a family history of GC), after resection of dysplastic lesions or in patients with dysplasia without visible lesion after a high-quality gastroscopy with chromoendoscopy.

These recommendations refer to the current management in pancreatic ductal adenocarcinoma (PDAC), a neoplasia characterised by an aggressive course and extremely poor prognosis. The recommendations regard diagnosis, surgical, adjuvant and palliative treatment, with consideration given to endoscopic and surgical methods. A vast majority of the statements are based on data obtained in clinical studies and experts’ recommendations on PDAC management, including the following guidelines: International Association of Pancreatology/European Pancreatic Club (IAP/EPC), American Society of Clinical Oncology (ASCO), European Society for Medical Oncology (ESMO), National Comprehensive Cancer Network (NCCN) and Polish Society of Gastroenterology (PSG) and The National Institute for Health and Care Excellence (NICE). All recommendations were voted on by members of the Working Group of the Polish Pancreatic Club. Results of the voting and brief comments are provided with each recommendation.

Malignant disease

1 ESGE recommends placement of partially or fully covered self-expandable metal stents (SEMSs) for palliation of malignant dysphagia over laser therapy, photodynamic therapy, and esophageal bypass.

Strong recommendation, high quality evidence.

2 ESGE recommends brachytherapy as a valid alternative, alone or in addition to stenting, in esophageal cancer patients with malignant dysphagia and expected longer life expectancy.

Strong recommendation, high quality evidence.

3 ESGE recommends esophageal SEMS placement for sealing malignant tracheoesophageal or bronchoesophageal fistulas.

Strong recommendation, low quality evidence.

4 ESGE does not recommend SEMS placement as a bridge to surgery or before preoperative chemoradiotherapy because it is associated with a high incidence of adverse events. Other options such as feeding tube placement are preferable.

Strong recommendation, low quality evidence.

Benign disease

5 ESGE recommends against the use of SEMSs as first-line therapy for the management of benign esophageal strictures because of the potential for adverse events, the availability of alternative therapies, and their cost.

Strong recommendation, low quality evidence.

6 ESGE suggests consideration of temporary placement of self-expandable stents for refractory benign esophageal strictures.

Weak recommendation, moderate quality evidence.

7 ESGE suggests that fully covered SEMSs be preferred over partially covered SEMSs for the treatment of refractory benign esophageal strictures because of their very low risk of embedment and ease of removability.

Weak recommendation, low quality evidence.

8 ESGE recommends the stent-in-stent technique to remove partially covered SEMSs that are embedded in the esophageal wall.

Strong recommendation, low quality evidence.

9 ESGE recommends that temporary stent placement can be considered for the treatment of leaks, fistulas, and perforations. No specific type of stent can be recommended, and the duration of stenting should be individualized.

Strong recommendation, low quality of evidence.

10 ESGE recommends considering placement of a fully covered large-diameter SEMS for the treatment of esophageal variceal bleeding refractory to medical, endoscopic, and/or radiological therapy, or as initial therapy for patients with massive bleeding.

Strong recommendation, moderate quality evidence.
