ABSTRACT
The authors present a 57-year-old patient with synchronous left atrial myxoma and gastric cancer undergoing staged treatment. Distal gastrectomy with gastroduodenostomy at the first stage was followed by resection of the left atrial myxoma after 22 days. Postoperative period was uneventful after both interventions. The follow-up examination revealed favorable clinical status and no cancer progression.

OBJECTIVE: To summarize the results of pancreaticoduodenectomy (PD) for pancreatic tumors and complications of chronic pancreatitis regarding prediction and prevention of postoperative complications. MATERIAL AND METHODS: There were 336 PD procedures between 2016 and mid-2022 in two centers. We assessed the factors influencing specific postoperative complications (postoperative pancreatitis, pancreatic fistula, gastric stasis, arrosive bleeding). Several risk factors were distinguished: baseline pancreatic disease and tumor size, CT-signs of a «soft¼ gland, intraoperative assessment of the pancreas, number of functioning acinar structures. We assessed surgical prevention of pancreatic fistula via preserving adequate blood supply to the pancreatic stump. The last one is provided by extended pancreatic resection and reconstructive stage of surgery, i.e. Roux-en-Y hepatico- and duodenojejunostomy with isolation of pancreaticojejunostomy on the second loop. RESULTS: Postoperative pancreatitis underlies specific complications after PD. The risk of pancreatic fistula in case of postoperative pancreatitis increases by 5.3 times compared to patients without pancreatitis. Postoperative pancreatic fistula is more common in patients with T1 and T2 tumors. According to univariate analysis, only pancreatic fistula significantly affects the risk of gastric stasis. Among 336 people who underwent PD, pancreatic fistula occurred in 69 patients (20.5%), gastric stasis - in 61 (18.2%), pancreatic fistula complicated by arrosive bleeding - in 45 (13.4%) patients. Mortality rate was 3.6% (n=15). CONCLUSION: Modern prognostic criteria are valuable to predict specific complications after PD. A promising way to prevent postoperative pancreatitis can be extended pancreatic resection considering angioarchitectonics of the pancreatic stump. Roux-en-Y pancreaticojejunostomy is advisable to reduce aggressiveness of pancreatic fistula.

AIM: To optimize surgical treatment of multiple and advanced pancreatic tumors. MATERIAL AND METHODS: There were 852 patients with various pancreatic tumors for the period 2011 - September 2019. Duodenopancreatectomy (DPE) was performed in 18 patients. Locally advanced ductal adenocarcinoma was diagnosed in 10 patients, acinar cell carcinoma - in 1 patient, multiple neuroendocrine tumors - in 4 cases, intraductal papillary mucinous tumor - in 2 patients, multiple metastases of renal cell carcinoma - in 1 patient. This procedure was avoided in 9 patients who underwent alternative operations: pancreatoduodenectomy (PDE) with pancreatic body resection for intraductal papillary mucinous tumor - 5 cases, two-stage (2) and one-stage (1) distal pancreatectomy and PDE for multiple neuroendocrine tumors - 2 patients, simultaneous pancreatic head resection and distal pancreatectomy for multiple metastases of renal cell carcinoma - 1 patient. RESULTS: Postoperative complications occurred in 14 patients after DPE (77.8%) and in 5 patients after alternative operations (55.5%). Alternative procedures in patients with neuroendocrine tumors, intraductal papillary mucinous tumors and metastases of renal cell carcinoma ensured radical surgical treatment. These patients did not need for insulin replacement therapy and enzyme drugs. CONCLUSION: Strict adherence to oncological canons and differentiated approach in patients with multiple neuroendocrine tumors, metastases of renal cell carcinoma and intraductal papillary mucinous tumors are essential to avoid DPE in some cases in favor of alternative operations.
