Abstract:
Objective:To study the relationship between pancreaticobiliary maljunction (PBM) with cholangiopancreatic diseases, and to evaluate the efficacy and safety using endoscopic therapy for PBM.Methods:The clinical data of 734 patients treated with ERCP at the Affiliated Hospital of Guizhou Medical University from May 2016 to April 2020 were analyzed retrospectively. Of 31 PBM patients who were finally included in this study, there were 23 patients with benign diseases and 8 patients with malignant diseases. Using the diameter of bile duct, these patients were divided into two groups: dilated bile duct group and the non-dilated bile duct group. The general characteristics of patients, incidences of cholangiopancreatic disease, endoscopic treatment, therapeutic efficacy and follow-up data were analyzed.Results:Of the 31 patients with PBM, 11 were males and 20 were females, aged (56.7±16.2) years. There were 4 patients with choledochal cyst (12.9%) and 6 patients with biliary cancer (19.4%). The incidences were significantly higher than those in non-PBM patients (0.9% and 5.3%, respectively, P<0.05). All 31 patients with PBM underwent endoscopic EST treatment, including 15 patients (48.4%) treated with endoscopic naso-biliary drainage (ENBD), 9 patients (29.0%) with endoscopic retrograde biliary drainage (ERBD), 4 patients (12.9%) with endoscopic papillary balloon dilatation (EPBD)+ ENBD, 1 patient (3.2%) with endoscopic metal biliary endoprothesis (EMBE)+ ENBD, 1 patient with ERBD+ endoscopic retrograde pancreatic drainage (3.2%), and 1 patient with EPBD+ ERBD+ EMBE (3.2%). The operative success rate was 100%. Serum AST, ALT, ALP, GGT, TBil and DBil levels of patients in the benign group and malignant group were significantly decreased postoperatively when compared with the preoperative levels (all P<0.05). One patient (3.2%) developed post ERCP pancreatitis. The preoperative and postoperative NRS scores of the patients in the benign group were 7(6, 8) points compared to 0 (0, 1) points, respectively ( P<0.05). All the 23 patients in the benign group were followed up for (25.13±12.90) months. There were no patients who were loss to follow-up. There was no malignant transformation. Three PMB patients with dilated bile ducts still had attacks of abdominal pain or jaundice. The symptoms of the remaining 20 patients were completely relieved, giving a treatment efficacious rate of 87.0% (20/23). Conclusions:PBM was closely related to choledochal cysts, biliary cancer and other diseases. Endoscopic treatment was efficacious and safe, and provided a safe and feasible treatment in preventing future cholangiopancreatic attacks.
