ABSTRACT

BACKGROUND: Endoscopic retrograde cholangiopancreatography may fail because of malignant involvement of the second portion of the duodenum and the major papilla. Alternatives include percutaneous transhepatic biliary drainage (PTBD) or surgical bypass. Endoscopic ultrasonography-guided choledochoduodenostomy (EUS-CD) has been reported as an alternative. OBJECTIVE: To prospectively compare EUS-CD and PTBD in patients with unresectable malignant biliary obstruction. DESIGN: Prospective and randomized study. SETTING: Tertiary center. MAIN OUTCOME MEASUREMENTS: Success and efficacy comparison EUS-CD with PTBD. RESULTS: Twenty-five subjects were randomized (13 EUS-CD and 12 PTBD). Mean age was 67 years (SD, 11.9). The 2 groups were similar before intervention in terms of quality of life [EUS-CD (58.3) vs. PTBD (57.8); P=0.78], total bilirubin (16.4 vs. 17.2; P=0.7), alkaline phosphatase (539 vs. 518; P=0.7), and gamma-glutamyl transferase (554.3 vs. 743.5; P=0.56). All procedures were technically and clinically successful in both groups. At 7-day follow-up there was a significant reduction in total bilirubin in both the groups (EUS-CD, 16.4 to 3.3; P=0.002 and PTBD, 17.2 to 3.8; P=0.01), although no difference was noted comparing the 2 groups (EUS-CD to PTBD; 3.3 vs. 3.8; P=0.2). There was no difference between the complication rates in the 2 groups (P=0.44), EUS-CD (2/13; 15.3%) and PTBD (3/12; 25%). Costs were similar in the 2 groups also ($5673-EUS-CD vs. $7570-PTBD; P=0.39). LIMITATIONS: Small sample size and single center study. CONCLUSIONS: EUS-CD can be an effective and safe alternative to PTBD with similar success, complication rate, cost, and quality of life.

ABSTRACT

BACKGROUND: Self-expandable metal stents (SEMS) are often used for biliary drainage due to obstruction of neoplastic etiology, with better results than plastic stents, but seldom for biliary drainage of benign etiology. OBJECTIVE: Primary end point: Verify bile duct patency after placement of self-expandable metal and (multiple) plastic stents in patients with benign strictures resulting from bile duct surgery with follow-up above five years. Secondary end point: Evaluate long-term complication rate in patients with metal self-expandable and plastic stents. RESULTS: Self-expandable stents were placed in 15 patients and multiple plastic stents in 16. Mean age was 45 years with prevalence of female patients in both groups and no statistical difference between groups was observed (SEMS: 66.7%; plastic multistent: 62.5%; p=0.8). Complication rate resulting from stents occurred more often in the metal stent group (40% versus 25%; p=0.37). In the metal stent group, most frequent complications were hemorrhage (n=3; 20%), stent migration (n=2; 13.3%) and perforation (n=1; 6.7%). In plastic multistent group, most frequent complications were perforation (n:2; 12.5%), hemorrhage (n=1; 6.2%) and ulcer (n=1; 6.2%). Long-term patency rate after biliary drainage was higher in the self-expandable metal stent group, SEMS: 81.67% ± 2.56; CI: 76.47-86.54; plastic multistent: 71.88% ± 2.93; CI: 66.08-77.27. CONCLUSION: The temporary passage of partially covered self-expandable metal stents is a feasible option for patients with benign bile duct strictures.

ABSTRACT

FUNDAMENTO: Los Stent de metal autoexpandibles se utilizan a menudo para el drenaje biliar en obstrucción de origen neoplásico, con mejores resultados que los stents plásticos, pero son rara vez utilizados en el drenaje biliar en estenosis de etiología benigna. OBJETIVO: El objetivo final primario: Es verificar la permeabilidad de la vía biliar después de la colocación de los stents auto-expandible de metal y (múltiples) prótesis plásticas en pacientes con estenosis benignas derivadas de la cirugía del conducto biliar con un seguimiento superior a cinco años. Punto final secundario: Evaluar a largo plazo la tasa de complicaciones en pacientes con stents metálicos autoexpandibles y plástico. RESULTADOS: Los stents autoexpandibles de metal se colocaron en 15 pacientes y múltiples stents de plástico en 16. La edad media fue de 45 años, con prevalencia de pacientes de sexo femenino en ambos grupos y no hubo diferencia estadística entre los grupos se observó (Stent metálico: 66,7%; plástico multistent: 62,5%, p = 0,8). La tasa de complicaciones resultantes de los stents fueron más frecuentes en el grupo de stent de metal (40% versus 25%, p = 0,37). En el grupo de stent de metal, las complicaciones más frecuentes fueron hemorragia (n = 3; 20%), la migración del stent (n = 2; 13,3%) y perforación (n = 1; 6,7%). En el grupo multistent plástica, las complicaciones más frecuentes fueron la (n: 2, un 12,5%), hemorragia (n = 1; 6,2%) y la úlcera (n = 1; 6,2%). A largo plazo la tasa de permeabilidad tras el drenaje biliar fue mayor en el grupo de metal autoexpandible, SEMS: 81,67% ± 2,56, IC: 76,47-86,54; plástico multistent: 71,88% ± 2,93, IC: 66.08-77.27. CONCLUSIÓN: El paso temporal de los stents metálicos cubiertos parcialmente auto-expandible es una opción viable para los pacientes con estenosis benignas del conducto biliar.
