A clinical case of successful surgical treatment of a patient with chronic pancreatitis, complicated by suppuration of a postnecrotic cyst and the formation of a cysto-gastric fistula. As a result of the conservative and minimally invasive treatment, the pseudocyst was drained, and the cystogastric fistula was closed. The staged treatment was completed by resection of the head of the pancreas with the formation of an anastomosis.

Pancreatic pleural fistula is one of the rare and difficulty verifying complication of chronic pancreatitis. We present a rare medical case of a patient with chronic pancreatitis complicated by pancreatic pleural fistula with the formationof multiple lung abscesses. At the same time, the success of the treatment of the patient was due to the staged treatment and the participation of a multidisciplinary team of specialists.
