- Abstract
Objective: To evaluate the early outcomes of radical surgical treatment of patients with resectable periampullary tumors and previous acute pancreatitis (AP)., Material and Methods: A retrospective analysis included 9 patients. AP was diagnosed in all patients at different times of preoperative period (post-manipulative AP in 7 cases, alcoholic AP in 2 cases). Pancreaticoduodenectomy was performed in 5 patients, total pancreatectomy (TP) - in 4 patients., Results: Severe postoperative complications occurred in 3 patients after pancreaticoduodenectomy. There were no complications after TP. All complications after pancreaticoduodenectomy were associated with a pancreatic stump that required urgent surgical interventions. Three patients died from surgical complications. All postoperative deaths were observed after pancreaticoduodenectomy., Conclusion: TP may be a safer surgical option compared to pancreaticoduodenectomy in patients with resectable periampiullary tumors and preoperative AP.

- Abstract
Background: Malignant potential of small (≤20 mm) nonfunctional pancreatic neuroendocrine tumors (sNF-PNET) is difficult to predict and management remain controversial. The aim of this study was to assess the prognosis of sporadic nonmetastatic sNF-PNETs., Methods: Patients were identified from databases of 16 centers. Outcomes and risk factors for recurrence were identified by uni- and multivariate analyses., Results: sNF-PNET was resected in 210 patients, and 66% (n = 138) were asymptomatic. Median age was 60 years, median tumor size was 15 mm, parenchyma-sparing surgery was performed in 42%. Postoperative mortality was 0.5% (n = 1), severe morbidity rate was 14.3% (n = 30), and 14 of 132 patients (10.6%) with harvested lymph nodes had metastatic lymph nodes. Tumor size, presence of biliary or pancreatic duct dilatation, and WHO grade 2-3 were independently associated with recurrence. Patients with tumors sized ≤10 mm were disease free at last follow-up. The 1-, 3- and 5-year disease-free survival rates for patients with tumors sized 11-20 mm on preoperative imaging were 95.1%, 91.0%, and 87.3%, respectively., Conclusions: In sNF-PNETs, the presence of biliary or pancreatic duct dilatation or WHO grade 2-3 advocate for surgical treatment. In the remaining patients, a wait-and-see policy might be considered., (Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

- Abstract
Background: Non-functional pancreatic neuroendocrine tumors (NF-PNET) are rare neoplasms being increasingly diagnosed. Surgical treatment or expectant management are both suggested for small NF-PNETs. The aim of this study was to evaluate the outcome of surveillance strategy for small NF-PNETs., Methods: A systematic search was performed up to March 2016 in MEDLINE, EMBASE and the Cochrane Library according to the PRISMA guidelines. Data was pooled using the random-effects model., Results: Nine articles including 344 patients with sporadic and 64 patients with MEN1 related NF-PNET were selected. Tumor growth was observed in 22% and 52%, development of metastases were reported on 0% and 9%, and rate of secondary surgical resection was 12% and 25% in patients with sporadic or MEN1 related NF-PNETs, respectively. All metastases (1 distant, 4 nodal) were reported by a single study in patients with MEN1. Reason for secondary surgery was tumor growth in half of patients undergoing surgery., Discussion: Expectant management of small asymptomatic, sporadic, NF-PNETs could be a reasonable option in highly selected patients. However, the level of evidence is low and longer follow-up is needed to identify patients could benefit from upfront surgery instead of expectant treatment., (Copyright © 2017 International Hepato-Pancreato-Biliary Association Inc.

- Abstract
Aim: To analyze the results of radical surgery for upper GI cancer in patients ≥80 years old., Material and Methods: For the period November 2010 - June 2015 there were 14 radical operations in elderly (≥80 years) patients with gastric, liver and pancreatic tumors. There were 4 Whipple procedures, 4 total and 2 distal gastrectomies, 1 total pancreatectomy as well as a central liver resection, one laparoscopic 5 segment resection and one 2, 3, 7 segment resection. We analyzed blood loss, duration of surgery, 90-day mortality, morbidity (Dindo-Clavien scoring), length of hospital-stay., Results: Blood loss ranged from 0 to 1500 ml, mean duration of surgery - from 150 to 560 min. There was one case of in-hospital mortality: one patient after a Whipple procedure died in 17 days after surgery due to massive arrosive bleeding. Complications developed in 8 patients, 3 of them required reoperation. Mean hospital-stay was 15±6 (8-29) days., Conclusion: Advanced upper GI surgery for cancer is feasible in octagenarians and does not lead to inappropriate mortality and morbidity. Comprehensive preoperative examination alongside with enhanced recovery protocol are prerequisites for this type of surgery.

- Abstract
Aim: To assess safety and clinical-economic effectiveness of complex postoperative rehabilitation after pancreatoduodenectomy., Material and Methods: 73 patients were included in the study. Main group consisted of 39 patients who underwent accelerated postoperative rehabilitation that was developed in our clinic. In the control group of 34 patients this protocol was not applied. The main components of rehabilitation were multicomponent analgesia, early enteral nutrition, physical rehabilitation by using of exercise therapy and physiotherapy., Results: There were no significant differences in the incidence of postoperative complications and mortality (58.8% and 74.3%; p=0.213, 5.8% and 7.7%; p=0.678, respectively). Median of postoperative hospital-stay in the study group was 13 days (9; 16), in the control group - 15 days (9; 24). An estimated economic effect in the study group was 558 764, 84 rubles., Conclusion: Accelerated postoperative rehabilitation after pancreatoduodenectomy is safe and does not lead to increased number of postoperative complications and mortality. Developed protocol has clinical advantages and is cost-effective.
