RESUMO
Objective To evaluate curative effects of treatment of malignant biliary and gastric outlet-duodenal obstruction with endoscopically placed self-expandable metal stents.Methods A retrospective analysis was performed in 17 patients who underwent enteral stenting after placement of the biliary stent.The success rate of insertion,the effective palliation of biliary and duodenal obstruction,the rate of complication,recurrent stent obstruction and the median patency were observed.Results In 17 patients,biliary stenting were all performed for obstructive jaundice and then enteral stents were inserted.The levels of tatal billirubin [from (263.4 ± 62.5) μmol/L to (157.6 ± 25.1) μmol/L],direct billirubin [from (1233.2 ±66.5) μmol/L to (130.9 ± 27.7) μmol/L] and alkaline phosphatase [from (233.2 ± 66.5) IU/L to (130.9 ±27.7)IU/L] decreased significantly (P ＜0.01),and the gastric outlet score increased significandy [from (0.9 ± 1.1) points to (2.1 ±0.7) points] (P ＜0.01).No serious complication in all patients.Lifetime of patients ranged from 70 days to 332 days,and the median survival time was 192 day.Conclusion Combined biliary and enteral stenting is an effective method for palliation of malignant biliary and gastric outlet-duodenal obstruction.
RESUMO
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.
