This paper is an update of the diagnostic and therapeutic recommendations of the National Consultant for Gastroenterology and the Polish Society of Gastroenterology from 2012. It contains 46 recommendations for the diagnosis and treatment, both pharmacological and surgical, of Crohn's disease in adults. The guidelines were developed by a group of experts appointed by the Polish Society of Gastroenterology and the National Consultant in the field of Gastroenterology. The methodology related to the GRADE methodology was used to assess the quality and strength of the available recommendations. The degree of expert support for the proposed statement, assessment of the quality of evidence and the strength of the recommendation was assessed on a 6-point Likert scale. Voting results, quality and strength ratings with comments are included with each statement.

Neoplasms may be missed by CE, especially in the proximal SB. In overt obscure gastrointestinal bleeding, complementary endoscopic and/or radiologic diagnostic tests are indicated.

Five or more CMV IHC-positive cells per biopsy section were indicative of a greater colectomy risk. CMV infection was related to more severe inflammation. Blood CMV PCR is a useful tool in UC.

Because most esophageal cancers are diagnosed at an advanced stage, a majority of patients require palliative dysphagia treatment. Dysphagia severity and the need for repeated re-canalization procedures signifi cantly affect patients ' quality of life (QoL). The aim of this study was to establish whether combining argon plasma coagulation (APC) of the neoplastic esophageal tissue with another re-canalization method results in a longer dysphagia-free period compared with APC alone. METHODS:We conducted a randomized trial in 93 patients with malignant dysphagia. Patients were followed until death. We compared three regimens of esophageal re-canalization; APC combined with high dose rate (HDR) brachytherapy, APC combined with photodynamic therapy (PDT), and APC alone. The primary outcome measure was the dysphagia-free period following randomization. Secondary measures were survival, QoL, treatment-associated complications, and treatment tolerance. A per-protocol analysis was carried out. RESULTS:The time to fi rst dysphagia recurrence was signifi cantly different between each combination treatment group and the control group (overall test: P = 0.006; HDR vs. control, log-rank P = 0.002, PDT vs. control, log-rank P = 0.036), but not different between the combination groups (HDR vs. PDT, log-rank P = 0.36). The median time to fi rst dysphagia recurrence was 88, 59, and 35 days in the HDR, PDT, and control groups, respectively. There was no difference in overall survival between the study groups ( P = 0.27). No deaths, perforations, hemorrhages, or fi stula formations were attributed to treatment. The only major complication was fever, occurring in three PDT patients. Minor complications were observed signifi cantly more often in the combination treatment groups and included pain in both groups, transient dysphagia worsening, and skin sensitivity in the PDT group. The QoL 30 days after treatment in the HDR group was signifi cantly better than in the other groups.CONCLUSIONS: In patients with inoperable esophageal cancer, palliative combination treatment of dysphagia with APC and HDR or PDT was signifi cantly more effi cient than APC alone, and was safe and well tolerated. APC combined with HDR resulted in fewer complications and better QoL than APC with PDT or APC alone (CONSORT 1b).SUPPLEMENTARY MATERIAL is linked to the online version of the paper at
