Disconnected Pancreatic Duct Syndrome (DPDS) is an important but often overlooked complication of acute necrotising pancreatitis (ANP) that occurs due to necrosis of the main pancreatic duct (PD). This segmental necrosis leads on to disconnection between the viable upstream pancreatic parenchyma and the duodenum. The disconnected and functional segment of pancreas continues to secrete pancreatic juice that is not drained into the gastrointestinal tract and lead on to recurrent pancreatic fluid collections (PFC), refractory external pancreatic flstulae and chronic abdominal pain/recurrent pancreatitis. Because of lack of awareness of this important complication of ANP, the diagnosis of DPDS is usually delayed. The delay in diagnosis increases the morbidity of the disease as well as increase the cost of treatment and duration of hospital stay. Surgery has remained the cornerstone for management of patients with DPDS. The conventional surgical approaches have been either resection or internal drainage procedures. Surgery for DPDS in the setting of ANP is often difficult due to presence of local inflammation and extensive venous collaterals in the operative field due to splenic vein thrombosis and therefore is associated with significant morbidity. Advancement in therapeutic endoscopy, especially advent of therapeutic endoscopic ultrasound has opened an exciting new field of minimally invasive therapeutic options for management of DPDS. The present review discusses the current understanding of the clinical manifestations, imaging features and management strategies in patients with DPDS.
