Abstract
BACKGROUND
Patients with pancreaticobiliary maljunction (PBM) have a common channel (CC) that is too long, causing the Oddi sphincter not to directly affect the pancreaticobiliary junction. As a result, reflux between pancreatic juice and bile occurs, causing various pathological changes in the bile duct or pancreas. Exploring the application and mechanism of minimally invasive endoscopic shortening of the pancreatic bile duct CC channel in PBM has become particularly important, providing patients with another treatment option.
AIM
To investigate the clinical efficacy and safety of minimally invasive endoscopic common channel sphinctertomy (CCEST) in the treatment of patients with PBM.
METHODS
The clinical data of 35 PBM patients treated by minimally invasive CCEST were analyzed, and there were BP type (n = 19) and PB type (n = 16) PBM. All 35 patients underwent CCEST with the help of endoscopic retrograde cholangiopancreatography, and the therapeutic effects and complications of minimally invasive CCEST in PBM patients were analyzed.
RESULTS
A total of 35 patients were diagnosed with PBM, of whom 12 were male and 23 were female. The patients ranged in age from 3 to 89 years, with a mean age of (46 ± 26.38) years. CCEST was performed in all patients to reduce the length of the CC. Among the 35 patients with PBM, 18 (51.43%) had combined biliary and pancreatic duct stones and underwent intraoperative lithotripsy. First-time ERCP stone extraction was successful in 14 patients, with a success rate of 78% (14/18). One week after minimally invasive intervention therapy, the serum biochemistry and C-reactive protein (CRP) and bile amylase in the 35 patients showed a significant decrease compared to the preoperative levels (P < 0.05). Post-ERCP pancreatitis was observed in five patients, but no serious complications such as postoperative bleeding, gastrointestinal perforation, and severe pancreatitis occurred after symptomatic treatment. After a mean follow-up period of (22.05 ± 10.67) mo in the 35 patients, one patient was diagnosed with carcinoma of the bile duct and treated by surgery, and four were treated by ERCP again because of stone recurrence and achieved satisfactory efficacy. The total effective rate of the treatment was 88.6% (31/35).
CONCLUSION
PBM patients often present with an insidious onset. ERCP is a valuable procedure for the diagnosis of PBM. CCEST effectively improves biliopancreatic drainage in early-stage PBM patients by reducing the length of the common biliopancreatic confluence channel. CCEST is a safe and effective minimally invasive intervention for the treatment of PBM patients.
