    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 After that, the needle was withdrawn and a wire-guided needle knife was used to enlarge the site puncture in the duodenal wall.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.

    EUS-guided Choledochoduodenostomy Versus Hepaticogastrostomy A Systematic Review and Meta-analysis
    (2018) UEMURA, Ricardo S.; KHAN, Muhammad Ali; OTOCH, Jose P.; KAHALEH, Michel; MONTERO, Edna F.; ARTIFON, Everson L. A.
    Background and Aims: Endoscopic ultrasound-guided biliary drainage (EUS-BD) has emerged as an alternative in cases of endoscopic retrograde cholangiopancreatography (ERCP) failure. Two types of EUS-BD methods for achieving biliary drainage when ERCP fails are choledochoduodenostomy (CDS) or hepaticogastrostomy (HGS). However, there is no consensus if one approach is better than the other. Therefore, we conducted a systematic review and meta-analysis to evaluate these 2 main EUS-BD methods. Methods: We searched MEDLINE, Embase, Scopus, Cochrane database, LILACS from inception through April 8, 2017, using the following search terms in various combinations: biliary drainage, biliary stent, transluminal biliary drainage, choledochoduodenostomy, hepaticogastrostomy, endoscopic ultrasound-guided biliary drainage. We selected studies comparing CDS and HGS in patients with malignant biliary obstruction with ERCP failure. Pooled odds ratio (OR) were calculated for technical success, clinical success, and adverse events and difference of means calculated for duration of procedure and survival after procedure. Results: A total of 10 studies with 434 patients were included in the meta-analysis: 208 underwent biliary drainage via HGS and the remaining 226 via CDS. The technical success for CDS and HGS was 94.1% and 93.7%, respectively, pooled OR = 0.96 [95% confidence interval (CI) = 0.39-2.33, I-2 = 0%]. Clinical success was 88.5% in CDS and 84.5% in HGS, pooled OR = 0.76 (95% CI = 0.42-1.35, I-2 = 17%). There was no difference for adverse events OR = 0.97 (95% CI = 0.60-1.56), I-2 = 37%. CDS was about 2 minutes faster with a pooled difference in means of was -2.69 (95% CI = -4.44 to -0.95). Conclusion: EUS-CDS and EUS-HGS have equal efficacy and safety, and are both associated with a very high technical and clinical success. The choice of approach may be selected based on patient anatomy.

    Hepaticogastrostomy or choledochoduodenostomy for distal malignant biliary obstruction after failed ERCP: Is there any difference?
    (2015) ARTIFON, Everson L. A.; MARSON, Fernando P.; GAIDHANE, Monica; KAHALEH, Michel; OTOCH, Jose P.
    Background: EUS-guided biliary drainage (BD) is an evolving alternative technique for patients with malignant biliary obstruction for which ERCP failed. Objective: To compare the outcomes of 2 nonanatomic EUS-guided BD routes: hepaticogastrostomy (HPG) and choledochoduodenostomy (CD). Design: Prospective, randomized trial. Setting: Tertiary endoscopic referral center. Patients: Forty-nine patients with unresectable distal malignant biliary obstruction and failed ERCP were included. The HPG group had 25 patients and the CD group had 24 patients. Interventions: EUS-guided HPG or CD. In all procedures, a biliary puncture with a 19-gauge needle followed by cholangiography, wire advancement, track dilation, and self-expandable metal stent deployment were performed. Main Outcome Measurements: Technical and clinical success, quality of life, adverse events, and survival. Results: The technical success rate was 96% for HPG and 91% for CD. The clinical success rate was 91% for HPG and 77% for CD. The mean procedural time was 47.8 minutes for HPG and 48.8 minutes for CD. The mean scores of quality of life were similar during follow-up. The overall adverse event rate was 16.3% (20% for the HPG group and 12.5% for the CD group). One patient with a bile leak required percutaneous biloma drainage. There was no statistical difference between the 2 techniques and no difference with regard to survival time between the 2 groups. Limitations: Single-center study. Conclusion: HPG and CD techniques are similar in efficacy and safety. Both HPG and CD seem valid alternative options for BD in patients with distal malignant biliary obstruction after failed ERCP.

    Divertículo de Meckel perforado
    (2017) GATTO, Janaina; TAKADA, Jonas; OTOCH, Jose P.; KREVE, ernanda; LOSS, Francisco S.; ARTIFON, Everson L. A.
    We report a patient with diffuse peritonitis due to perforation of Meckel's diverticulum. This patient was referred to the operating room and underwent bowel resection segment encompassing the area of the diverticulum and terminoterminal primary enteroanastomosis on two levels with good evolution. The diverticulum complications are often related to the presence of ectopic mucosa, especially the gastric and pancreatic type. Since preoperative diagnosis is difficult and infrequent, in most cases this anomaly is confirmed only during surgery. Surgical resection of the affected intestinal segment is the mainstay of treatment in both diverticula diagnosed incidentally, as the complicated by inflammation, bleeding, obstruction or perforation. We conclude that in cases of acute abdomen punctured, the diagnosis of Meckel's diverticulum should be considered.
