ABSTRACT
Objective To investigate the therapeutic strategies, methods, safety and efficacy of simultaneous placement of sel--expanding metallic stent (SEMS) in the bile duct and duodenum under endoscope for treatment ofmalignant biliary and duodenal obstruction. Methods The clinical data of patients with obstructive jaundice combined with severe duodenal stricture, who were treated with simultaneous placement of biliary SEMS and duodental SEMS under endoscope during January 2009 to June 2012, were retrospectively analyzed. The success rate of endoscopic management, complications, relief of jaundice and results of gastric outlet obstruction scoring system (GOOSS) were analyzed. Results Totally ten patients meeting the criteria were analyzed in this study. The patients included 5 cases with pancreatic cancer, 2 with gallbladder cancer, 2 with cancer of bile duct and one with duodenal papilla caner. Five patients with type I duodenal stricture (without invading duodenal papilla) successfully received biliary stents through endoscopic retrograde cholangiopancreatography (ERCP) after placement of duodenal stents. One patient with type I duodenal stricture was implanted with a 9 cm duodenal stent before endoscopic anterograde cholangiopancreatography (EACP), then a SEMS was implanted in the bile duct through endoscopic ultrasonography-guided biliary drainage (EUS-BD). Three patientswith type H duodenal stricture (with invading duodenal papilla) underwent EACP and biliary stent placement through EUS-BD, and then the duodenal stent was deployed in duodenum after EACP. The patient with type m (away from the duodenal papilla) was implanted with biliary and duodenal stents. The success rate of endoscopic management was 100%. Two patients had self-controlled bleeding of intestinal mucosa, which was caused by endoscope friction when passing through the duodenal stricture, but without any continuous bleeding or perforation. Symptoms of jaundice and gastric outlet obstruction were greatly relieved after treatment. Conclusion For patients with unresectable malignant biliary obstruction combined with duodenal stricture, endoscopic placement of SEMS in the bile duct and duodenum simultaneously is a safe and effective method to palliate dual malignant obstruction via different endoscopic managements.
ABSTRACT
Objective To investigate the value, safety and efficacy of fully-covered self-expandable metallic stent (FCSEMS) in endoscopic retrograde cholangiopancreatography (ERCP) procedures for pancreatic-biliary diseases. Methods The clinical data of 56 patients with pancreatic-biliary diseases, who underwent FCSEMS treatment via ERCP from January 2008 to June 2012, were retrospectively analyzed. The stents of different lengths and types were chosen according to the condition of patients. The stentswere removed under endoscope. The therapeutic effects at end point, stent removing rate and associated complicationswere observed. Results FCSEMS was placed in 49 patients with benign stricture, including pos-- liver transplant stricture (32), iatrogenic biliary stricture (12) and chronic pancreatitis-associated stricture (5). The mean follow time was (15±8. 6) months (range 5-38 months), -the mean stent duration was (8.4±5. 3) months (1-15 months), and the effective rate was 89.8% (44/49). FCSEMS was placed in 7 patients with biliary complications, including bleeding after endoscopic sphincterotomy (EST) (4), perforation after EST (1), and bile leakage following liver transplantation (2). The mean follow time was (5±3. 7) months (range 1-12 months), themean stent duration was (1. 8±0. 5) months (1-8 months), and the effective rate was 100%. All FCSEMS were successfully retrieved. The short-term complication rate associated with stentwas 8.9% (5/56), including post-ERCP pancreatitis (2), early cholangitis (2) and cholecystitis (1). The long-term complication ratewas 12. 5% (7/56), including stent slip (2), stent translocation (3) and stent-associated cholangitis (2). Conclusion FCSEMS can not only be used to treat traditional benign pancreatic-biliary strictures, but alto serve as a potential substitute for safe and effective treatment of serious biliary complications.
ABSTRACT
Liver transplantation (LT) has become an important treatment for end stage hepatobiliary disorders. However, biliary complications following LT are common and greatly hamper the clinical efficacy. Endoscopic therapy has been the first-line modality for these biliary problems, though technically difficult and complex. We have managed more than 1 000 cases of complications following LT via endoscopic approach. Here we summarized the therapeutic methods and strategies of our center, hoping to provide evidence for better clinical practice.
ABSTRACT
Objective To study on the metal clip installation to avoid post-operative bleeding in pa- tients accepted papilla sphinctecotomy.Methods One hundred and eighty five patients who accepted ERCP +EST were divided into two groups:Group 1 was given routine regimen alone(N=95),group 2,given routine regimen and metal clip to prevent post-operative bleeding.Results The postoperative bleeding hap- pened in 3(3.2%)cases of Group 1 and none in Group 2,there is significant difference between these two groups(P＜0.05).The breeding cases in group 1 were controlled by metal clip under endoscopy successful- ly.Conclusion Preventive usage of metal clip was significantly decreased the incidence of post-operative bleeding in EST patients.
