- 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 PinhataObjective. 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 After that, the needle was withdrawn and a wire-guided needle knife was used to enlarge the site puncture in the duodenal wall.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.
article 8 Citação(ões) na Scopus Surgical or endoscopic management for post-ERCP large transmural duodenal perforations: a randomized prospective trial(2015) ARTIFON, Everson L. A; K. MINATA, Mauricio; B. CUNHA, Marco Antonio; P. OTOCH, Jose; P. APARICIO, Dayse; K. FURUYA, Carlos; B. PAIONE, José L.Introduction: Duodenal perforations are an uncommon adverse event during ERCP. Patients can develop significant morbidity and mortality. Even though surgery has been used to manage duodenal complications, therapeutic endoscopy has seen significant advances. Objective: To compare endoscopic approach with surgical intervention in patients with duodenal perforations post-ERCP. Material and Methods: prospective randomized study in a tertiary center with 23 patients divided in 2 groups. Within 12 hours after the event, the patients underwent endoscopic or surgical approach. Endoscopic approach included closure of the perforation with endoclips and SEMS. Surgical repair included hepaticojejunostomy, suture of the perforation or duodenal suture. The success was defined as closure of the defect. Secondary outcomes included mortality, adverse events, days of hospitalization and costs. Results: The success was 100% in both groups. There was one death in the endoscopic group secondary to sepsis. There was no statistical difference in mortality or adverse events. We noticed statistical difference in favor of the endoscopic group considering shorter hospitalization (4.1 days versus 15.2 days, with p=0.0123) and lower cost per patient (U$14,700 versus U$19,872, with p=0.0103). Conclusions: Endoscopic approach with SEMS and endoclips is an alternative to surgery in large transmural duodenal perforations post-ERCP- Biliary Drainage in Patients With Unresectable, Malignant Obstruction Where ERCP Fails Endoscopic Ultrasonography-Guided Choledochoduodenostomy Versus Percutaneous Drainage(2012) ARTIFON, Everson L. A.; APARICIO, Dayse; PAIONE, Jose B.; LO, Simon K.; BORDINI, Andre; RABELLO, Carolina; OTOCH, Jose P.; GUPTA, KapilBackground: 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.
