The method of treatment of chronic pancreatitis, complicated by a complete pancreatic fistula with obstruction of the proximal part of the main pancreatic duct, under conditions of preservation of the left anatomical segment

Annotation. Chronic pancreatitis (CP) is a long-term disease that causes associated complications of the gastrointestinal tract. Pancreatic fistula (PF) is one of the complications of various diseases and pathology of the pancreas, as well as surgical interventions performed by various methods depending on the indications and the reason for their use. Not infrequently, this pathology is complicated by peritonitis with subsequent development of sepsis, which quite often results in the death of the patient. External PF, depending on its flow rate, is dangerous for the exhaustion of the patient, the formation of maldigestion syndrome, malabsorption, and hypoproteinemia. During 2016-2023, operations for PA and pleurisy were performed in 35 patients. In 5 (14.3%) of them, we performed our proposed surgical intervention in patients with complicated CP, for which the copyright was obtained for the work “Method of treatment of chronic pancreatitis complicated by a complete pancreatic fistula with obstruction of the proximal part of the Wirsung duct, under the conditions preservation of the left anatomical segment” No. 120597 dated July 18, 2023. The basis of a useful model is the task of creating such a method of treatment of CP, complicated by virsungolithiasis, a complete fistula of the PP and obstruction of the proximal part of the duct of the pancreas, which would allow, in addition to the removal of the pancreatic fistula, to remove the block in the head area in the simplest way, thus restoring the integrity of the tract while being more physiological and less traumatic with preservation of the tail of the pancreas and, accordingly, endocrine function.
