Method of forming a pancreatogastric anastomosis after pancreatoduodenal resection

Aim. To evaluate the reproducibility and safety of the developed pancreatogastric anastomosis with various surgical approaches during pancreatoduodenectomy.Materials and methods. The experience of surgical treatment of 47 patients with malignant tumours of the periampullary zone, who underwent pancreatoduodenectomy, was considered. The proposed variant of anastomose was performed to 14 (29.8%) patients: in 7 cases with a minimally invasive approach to perform pancreatoduodenectomy; and in 7 cases with an open approach. To compare retrospectively 33 (70.2%) patients who underwent pancreatogastric anastomosis according to the Bassi technique: 9 – with minimally invasive surgery, 24 – with open surgery. The frequency of pancreatic fistulas, the number of repeated interferences, and hospital mortality were taken into account.Results. A significant advantage of the new method of forming an anastomosis in the duration of the operation was noted in comparison with the Bassi technique. There were no statistically significant differences in blood loss while various types of anastomoses (p > 0.05). When using the proposed technique, the formation of pancreatic fistulas was not revealed. The development of pancreatic fistula was observed in 4 (16.7%) patients after open surgery and in 7 (77.8%) patients after minimally invasive Bassi anastomose formation. Reoperations were performed after open surgery in 3 (12.5%) cases and in 4 (44.4%) cases of minimally invasive surgery according to the Bassi technique. There were 2 (22.2%) deaths in the minimally invasive group.Conclusion. The proposed pancreatogastric anastomosis is applicable in clinical practice. This method allows to create relatively fast and less challenging anastomosis, including with a minimally invasive approach. The use of this technique makes it possible to reduce mortality and postoperative complications in patients with a “complex” pancreas.
