Carcinomas of the colon and rectum are the third most common in the world in men and second in women. About 60% of cases occur in developed countries. Colorectal carcinomas are observed more frequently in men than women. In Poland most cases of colorectal cancers occur after the age of 50 -about 94%, with more than 75% of cases in both sexes falls on the population of the elderly over 60 years. Approximately 20% of patients with colorectal cancer have distant metastasis at time of diagnosis. Up to 29% patients with colorectal cancer present symptoms of bowel obstruction such as: vomiting and abdominal pain. Due to age, serious multiple comorbidities and metastatic disease, colonic stenting is safe and effective alternative approach for palliation. The authors of this article presented a case of a 76-year-old Caucasian man who was admitted to the Department of Surgical Oncology because of colorectal carcinoma which was located in descending colon. Due to age and serious multiple comorbidities, doctors with the patient decided to palliative treatment by using self-expanding metallic stent. The authors performed a literature review on enteral metallic stents for the management of malignant colorectal cancers.

A 63-year-old female patient was admitted to the hospital for an in-depth diagnosis of accidentally found pancreatic cystic lesion. The lesion was detected by computed tomography scan and magnetic resonance imaging of the abdomen and identified as potentially malignant mucinous cystic neoplasm (MCN). Endoscopic ultrasound-guided fine-needle aspiration biopsy with the analysis of the fluid from the cyst was performed as well and it confirmed the malignancy of the cystic lesion. The patient was qualified for surgery and the final diagnosis based on histopathological examination of the surgical material confirmed MCN with the accompanying invasive pancreatic adenocarcinoma.
