    Endoscopic ultrasound-guided choledochoduodenostomy and duodenal stenting in patients with unresectable periampullary cancer: one-step procedure by using linear echoendoscope
    (2013) ARTIFON, Everson L. A.; FRAZAO, Mariana S. V.; WODAK, Stephanie; CARNEIRO, Fred Olavo A. A.; TAKADA, Jonas; RABELLO, Carolina; APARICIO, Dayse; MOURA, Eduardo Guimaraes Hourneaux De; SAKAI, Paulo; OTOCH, Jose Pinhata
    Objective. Describe a case series of endoscopic ultrasound (EUS)-guided choledochoduodenostomy (BUS-CD) associated with duodenal self-expandable metal stents (SEMS) placement using solely the linear echoendoscope in seven patients with obstructive jaundice and duodenal obstruction due to unresectable periampullary cancer. Material and methods. EUS-CD in the first portion of the duodenum, associated with duodenal SEMS placement was performed in seven patients with unresectable periampullary cancer with obstructive jaundice and invasive duodenal obstruction. Laboratory tests and clinical follow-up were performed until patient's death. The procedure was performed by an experienced endoscopist under conscious sedation. The puncture position was chosen based on EUS evaluation, at the common bile duct (CBD) above the tumor, through the distal part of the duodenal bulb. After that, the needle was withdrawn and a wire-guided needle knife was used to enlarge the site puncture in the duodenal wall. Then, a partially covered SEMS was passed over the guide, through the choledochoduodenal fistula. Duodenal SEMS placement was performed during the same endoscopic procedure. Results. The procedure was performed in seven patients, ranging between 34 and 86 years. Technical success of EUS-CD, by the stent placement, occurred in 100% of the cases. There were no early complications. Duodenal SEMS placement was effective in 100% of the cases that remained alive after a follow-up of 7 and 30 days. Conclusion. The results suggest therapeutic BUS one-step procedure drainage as an alternative for these patients, with good clinical success, feasible technique and safety.

    Role of EUS evaluation after endoscopic eradication of esophageal varices with band ligation
    (2016) CARNEIRO, Fred Olavo Aragao Andrade; RETES, Felipe Alves; MATUGUMA, Sergio Eiji; ALBERS, Debora Vieira; CHAVES, Dalton Marques; SANTOS, Marcos Eduardo Lera dos; HERMAN, Paulo; CHAIB, Eleazar; SAKAI, Paulo; D'ALBUQUERQUE, Luiz Augusto Carneiro; MALUF FILHO, Fauze
    Background and Aims: Variceal recurrence after endoscopic band ligation (EBL) for secondary prophylaxis is a frequent event. Some studies have reported a correlation between variceal recurrence and variceal rebleeding with the EUS features of paraesophageal vessels. A prospective observational study was conducted to correlate EUS evaluation of paraesophageal varices, azygos vein, and thoracic duct with variceal recurrence after EBL variceal eradication in patients with cirrhosis. Methods: EUS was performed before and 1 month after EBL variceal eradication. Paraesophageal varices, azygos vein, and thoracic duct maximum diameters were evaluated in predetermined anatomic stations. After EBL variceal eradication, patients were submitted to endoscopic examinations every 3 months for 1 year. We looked for EUS features that could predict variceal recurrence. Results: Thirty patients completed a 1-year endoscopic follow-up. Seventeen patients (57%) presented variceal recurrence. There was no correlation between azygos vein and thoracic duct diameter with variceal recurrence. Larger paraesophageal varices predicted variceal recurrence in both evaluation periods. Paraesophageal varices diameters that best correlated with variceal recurrence were 6.3 mm before EBL (52.9% sensitivity, 92.3% specificity, and .749 area under the receiver operating characteristic curve [AUROC]) and 4 mm after EBL (70.6% sensitivity, 84.6% specificity, and .801 AUROC). Conclusions: We conclude that paraesophageal varices diameter measured by EUS predicts variceal recurrence within 1 year after EBL variceal eradication. Paraesophageal diameter after variceal eradication is a better recurrence predictor, because it has a lower cut-off parameter, higher sensitivity, and higher AUROC.
