A meta-analysis on the efficacy of endoscopic ultrasonography for treatment of pancreatic cancer.

OBJECTIVE: This study aimed to systematically evaluate the efficacy and safety of Endoscopic Ultrasonography (EUS) for the treatment of pancreatic cancer. METHODS: The PubMed, Embase, Web of Science, and Google Scholar databases were searched from the inception of the databases to June 2022. RevMan 5.3.0 software was utilized for data analysis. In total, 13 self-descriptive studies, which enrolled 382 patients, were finally included. RESULTS: It was revealed that EUS for the treatment of pancreatic cancer exhibited a lower incidence of adverse reactions (Relative Risk Ration [RR = 0.23], 95 % Confidence interval [95 % CI 0.23-0.23]), a higher success rate (RR = 0.90, 95 % CI 0.90-0.90), and a low failure rate (RR = 0.06, 95 % CI 0.06-0.06). Moreover, EUS-guided Celiac Plexus Neurolysis (EUS-CPN) not only significantly relieved pancreatic cancer patients' pain (RR = 0.83, 95 % CI 0.83-0.83), but also significantly eliminated pain in some patients (RR = 0.09, 95 % CI 0.09-0.09). The effects of EUS on pancreatic cancer treatment were satisfactory, and few adverse reactions were found. CONCLUSION: Owing to the restricted sample size in this meta-analysis, primarily consisting of descriptive studies, it was imperative to conduct more rigorously designed, multi-center, long-term follow-up, larger sample, and Randomized Controlled Trials (RCTs) to validate the findings.

Derivación biliodigestiva guiada por ultrasonografía endoscópica en el paciente con adenocarcinoma de páncreas y obstrucción de la vía biliar estadio IV: reporte de caso / Biliodigestive shunt guided by endoscopic ultrasonography in patient with stage IV pancreatic adenocarcinoma and obstruction of the bile duct. A case report

Resumen La endosonografía endoscópica es una alternativa que sirve como guía para la realización de derivaciones biliodigestivas en los casos en los que la colangiopancreatografía retrógrada endoscópica (CPRE) ha fallado. Se han descrito técnicas como la coledocoduodenostomía o coledocoantrostomía guiadas por ultrasonografía endoscópica (USE). Se describe el caso de una paciente de 72 años con adenocarcinoma de páncreas, compromiso portal y de paredes duodenales, en quien se usó la CPRE para intentar una derivación paliativa y fue fallida, por lo cual se realizó la colocación de un stent metálico guiado por endosonografía endoscópica, con adecuada respuesta clínica al tratamiento. En conclusión, el procedimiento es seguro y la endosonografía es una vía alterna efectiva en los casos de CPRE fallidas para lograr derivaciones biliares en casos de obstrucción de la vía biliar de origen maligno.

Abstract Endoscopic endosonography is an alternative to guide biliodigestive shunting in cases where endoscopic retrograde cholangiopancreatography (ERCP) has failed. Techniques such as choledoduodenostomy or choledochoantrostomy guided by endoscopic ultrasonography have been described. This is the case of a 72-year-old patient with pancreatic adenocarcinoma, portal vein and duodenal wall involvement, in whom ERCP to try a palliative shunt failed. Therefore, a metal stent was placed using endoscopic endosonography, with adequate clinical response to the procedure and treatment. It is concluded that the procedure is safe and that endosonography is an effective alternative in cases of ERCP failure to achieve biliary bypass in cases of malignant biliary obstruction.
