Necrotizing pancreatitis represents a severe variant of acute pancreatitis characterized by the death of pancreatic tissue (necrosis). This condition commonly stems from inflammation and damage to the pancreas, leading to the development of areas of dead tissue within the organ. Pleural effusion, on the other hand, involves the accumulation of fluid within the pleural cavity. Typically, these effusions are of mild to moderate severity and tend to occur on the left side. In the following case report, we present a 25-year-old male who was diagnosed with necrotizing pancreatitis and bilateral pleural effusion. It is important to emphasize that cardiopulmonary physiotherapy plays a crucial role in managing pleural effusion. Such interventions, which encompass breathing exercises and thoracic expansion exercises, are pivotal for optimizing lung ventilation, enhancing oxygen levels, and preventing complications such as atelectasis and pneumonia. By boosting oxygenation and improving lung compliance, physiotherapy helps reduce the risk of respiratory problems and expedites the recovery process. This approach enables young individuals to regain their lung function and overall quality of life. In this particular case, the patient received medical management and pulmonary rehabilitation, resulting in a decrease in the Modified Medical Research Council Scale score and an improvement in the six-minute walk test (6 MWT), which subsequently enhanced their quality of life.
