Abstract:
Objective:To evaluate the curative effect, safety and feasibility of percutaneous transhepatic cholangio drainage(PTCD) combined with balloon dilatation in treating benign biliary-enteric anastomosis stricture(BBES).Methods:The clinical data of 33 patients with benign biliary-enteric anastomosis stricture, who were admitted to the First Affiliated Hospital of Zhengzhou University during the period from January 2013 to May 2019, were retrospectively analyzed. There were 23 cases of benign etiology and 10 cases of malignant etiology, benign strictures of which 15 cases were located in the hepatic hilum and of which 18 cases outside of it. All patients were considered as benign stenosis by at least two imaging examinations of magnetic resonance imaging of pancreatic or enhanced MRI or enhanced CT, laboratory examinations of tumor markers and other clinical data before operation. 10 cases of malignant etiology were confirmed by intraoperative biopsy and pathology. All patients were treated with balloon dilatation at an interval of 1 to 4 weeks after PTCD. The changes of clinical symptoms, bilirubin and liver function before and after operation were compared and analyzed, and the postoperative complications and anastomotic patency rate were followed up.Results:PTCD combined with balloon dilatation was performed successfully in all patients, and the success rate was 100%. After operation, the benign biliary-enteric anastomosis stricture was significantly improved in all patients, and the clinical symptoms were improved obviously. The liver function and bilirubin decreased significantly in all patients after operation, and there was significant statistical significance ( P<0.05). There is no serious complications such as biliary bleeding and biliary fistula were found after operation. At 3 months, 6 months, 12 months, 24 months and 36 months after operation, the anastomotic patency rates of all patients were 90.9%(30/33), 72.7%(24/33), 63.6%(21/33), 63.6%(21/33), 60.6%(20/33), respectively. During the whole follow-up period, anastomotic restenosis happened in 13 patients, of which 9 cases with restenosis, the benign stenosis site of the anastomosis was the hepatic hilum and of which 4 cases located on the outside of the hepatic hilum. After treatment, the incidence of benign restenosis of the anastomosis at the hepatic hilum (60.0%, 9/15) was higher than that at outside of the hepatic hilum (22.2%, 4/18) and it's statistically significant ( P<0.05). Among the 13 patients with recurrence of BBES, 4 cases underwent choledochojejunostomy for malignant causes and 9 cases with benign causes. The recurrence rates after the first balloon dilatation were 40.0% (4/10) and 39.1% (9/23), respectively, and the average recurrence time was 5.8 months and 6.8 months respectively, the difference was not statistically significant( P>0.05). Conclusion:For the treatment of benign biliary-enteric anastomosis stricture, percutaneous transhepatic cholangio drainage combined with balloon dilatation with reliable curative effect, with high safety and less trauma, with less operative complications, and with repeatability, so it is worth applying in clinic.
