Objective: To analyze the immediate results of PDE in patients younger and older 70 years., Material and Methods: The study included patients who underwent PDE for various indications from March 2010 to February 2019. All patients are divided into 2 groups: <70 years old and ≥70 years old. Primary endpoints were postoperative mortality and complication rate., Results: There were 110 procedures within 9 years. There were 93 patients aged <70 years (group 1) and 17 patients aged ≥70 years (group 2). ASA (American Society of Anesthesiologists) and PMP scores (Preoperative Mortality Predictor) were higher in group 2: 3 (2-3) vs 2 (1-3) (p=0,002) and 12 (6-15) vs 6.5 (5-15) (p<0.001), respectively. Mortality rate was higher in group 2 (11.7% vs. 3.2%) without statistical significance (p=0.16). Overall morbidity (72% vs 76%; p=1.0), incidence of major complications grade ≥IIIa (29% vs 29%), delayed gastric emptying B/C (17.2% vs 17.6%), pancreatic fistula grade B/C (23.6% vs 35.3%, p=0.3), biliary fistula grade B/C (7.5% vs 11.8%; p=0.62), postoperative hospital-stay [22 (8-165) days vs 23 (9-71) days; p=0.92] were comparable in both groups., Conclusion: Short-term results of PDE in patients aged <70 and ≥70 years are comparable despite higher ASA and PMP scores in the group 2. General status and concomitant diseases should be considered during selection of patients with resectable tumors for PDE. Age per se is not a contraindication for surgery.

Aim: To analyze immediate and long-term results of surgical treatment of patients with non-functioning pancreatic neuroendocrine tumors (pNETs)., Material and Methods: Outcomes in 21 patients with non-functioning pNETs were retrospectively analyzed., Results: Long-term results were followed-up in 18 (85%) cases, median follow-up was 39 months. Postoperative mortality was 4.7%. The incidence of postoperative complications Clavien-Dindo degree IIIA and over was 20.8%, overall 5-year survival - 89%, desease-free 5-year survival - 78%., Conclusion: At present time surgical intervention remains the only radical method of non-functioning pNETs management. Threshold tumor dimension should be 15 mm that determines surgical intervention or active surveillance. From an oncological point of view tumor enucleation is permissible only in case of small dimensions (up to 2 cm) and full confidence in low degree of malignancy. Lymphadenectomy should be performed in all cases in standard fashion because lymph node involvement is reliably poor prognostic sign.

Aim: To present own experience of surgical treatment of isolated pancreatic metastases of renal cell carcinoma., Material and Methods: There are 3 cases of pancreatic metastases of renal cell carcinoma. They were diagnosed in women aged 55, 66 and 67 years in 9, 11 and 23 years after nephrectomy respectively., Results: The tumors were placed in head (60 mm), body (10 and 5 mm) and tail (30 mm) of the pancreas. There were 2 distal pancreatectomy with splenectomy and 1 pancreatoduodenectomy. All patients are alive within 39, 49 and 8 months after surgery respectively. One woman has been diagnosed pulmonary metastases after 19 months. 20-month sunitinib administration contributes to regression of the disease. There was no recurrent disease in other two patients., Conclusion: Isolated pancreatic metastases of renal cell carcinoma can occur in decades after nephrectomy. Therefore, lifelong follow-up is necessary. Pancreatectomy for focal lesion is associated with good long-term outcome.
