The clinical diagnosis and treatment of 32 cases of pancreatic duct stones / 中华内分泌外科杂志

ABSTRACT

Objective:To investigate the diagnosis, classification and treatment of pancreatic duct stones (PDS) .Methods:Clinical data and prognosis of 32 patients with PDS treated in our hospital from Jan. 2010 to Dec. 2019 were retrospectively analyzed. The treatment methods were summarized.Results:All 32 cases were diagnosed with PDS by imaging examinations such as B ultrasonography, CT, endoscopic retrograde cholangiopancreatography (ERCP) or magnetic resonance cholangiopancreatography (MRCP) . The diagnosis accuracy was 81.3% (26/32) for B-ultrasound, 86.2% (25/29) for CT, 90.4% (19/21) for MRCP, and 100% (8/8) for ERCP. According to the location of stones and intraoperative exploration, the 32 patients were divided into 3 groups Type I, 17 patients, the stones were located in the main pancreatic duct; TypeⅡ, 11 patients, the stones were located in both main and branch pancreatic duct; Type Ⅲ, 4 patients, the stones were located in the branch pancreatic duct. Different treatment methods were employed according to the different types. No patient died in the perioperative period. 11 (34.3%) patients had postoperative complications. 3 (9.3%) patients had postoperative residual stones. 32 cases were followed up for a period of 6 to 60 months. The abdominal pain and steatorrhea disappeared or significantly improved postoperatively. 2 patients complicated with pancreatic cancer died 12 to 35 months after operation.Conclusions:The treatment and diagnosis of the PDS still remains complicated. Imaging examinations are the main methods for diagnosis of PDS. The accurate classification and individual treatment are important. Surgery is the most commonly used method for PDS.
