Rare complications of acute pancreatitis: Clinical cases

Background. Acute pancreatitis is recognized as a common disease, occasionally accompanied by the development of local complications that require surgical debridement. Rare complications of pancreatitis may occur in clinical practice, which is one of the reasons for their untimely diagnosis and treatment. Pancreaticopleural fistula and high small bowel obstruction develop in less than 1% of acute pancreatitis cases. Therefore, possible options for management of these complications are considered valuable. Description of clinical cases. The clinical examples, provided in the present paper, describe pancreaticopleural fistula and high small bowel obstruction that develop against the peripancreatic mass in the abdominal cavity. Patient K., 44, was hospitalized to the Regional Clinical Hospital of Emergency Medical Care, Krasnodar Krai, and preliminary diagnosed with bilateral hydrothorax and type II respiratory failure; pleural puncture was performed. Following the extended examination, a clinical diagnosis was made as follows: “Acute necrotic pancreatitis spreading to a pancreatic tail cyst. Reactive double pleurisy”. The postoperative period was indicated with repeated recurrence of right hydrothorax, and pancreaticopleural fistula (diagnosed by measuring amylase activity in the brown fluid effused from the right pleural cavity, which appeared to be 41216 IU/l (not normally determined)). The right pleural cavity and pseudocyst of the pancreatic tail were drained, resulting in obliteration of the pancreatbcopleural fistula. Patient V., 50, was hospitalized and transferred to the surgical department of the Regional Clinical Hospital No. 2, Krasnodar Krai, and diagnosed with “pancreonecrosis, extensive purulent-necrotic peripancreatitis.” The patient underwent puncture-drainage treatment. The postoperative period was complicated by acute small bowel obstruction. Surgical treatment involved Braun enteroesterostomy. The patient recovered. Conclusion. Pancreaticopleural fistula refers to a rare complication of acute pancreatitis, manifested by hydrothorax. Its diagnosis is based on the determination of amylase activity in the effusion. Drainage of the pleural cavity and pancreatic pseudocyst contributes to obliteration of the fistula. The intestinal obstruction, another complication of pancreatitis, requires open surgical treatment when a conservative therapy appears ineffective.
