    Endoscopic ultrasound fine needle aspiration vs fine needle biopsy in solid lesions: A multi-center analysis
    (2021) MOURA, Diogo Turiani Hourneaux; MCCARTY, Thomas R.; JIRAPINYO, Pichamol; RIBEIRO, Igor Braga; FARIAS, Galileu Ferreira Ayala; MADRUGA-NETO, Antonio Coutinho; RYOU, Marvin; THOMPSON, Christopher C.
    BACKGROUND While endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is considered a preferred technique for tissue sampling for solid lesions, fine needle biopsy (FNB) has recently been developed. AIM To compare the accuracy of FNB vs FNA in determining the diagnosis of solid lesions. METHODS A retrospective, multi-center study of EUS-guided tissue sampling using FNA vs FNB needles. Measured outcomes included diagnostic test characteristics (i.e., sensitivity, specificity, accuracy), use of rapid on-site evaluation (ROSE), and adverse events. Subgroup analyses were performed by type of lesion and diagnostic yield with or without ROSE. A multivariable logistic regression was also performed. RESULTS A total of 1168 patients with solid lesions (n = 468 FNA; n = 700 FNB) underwent EUS-guided sampling. Mean age was 65.02 +/- 12.13 years. Overall, sensitivity, specificity and accuracy were superior for FNB vs FNA (84.70% vs 74.53%; 99.29% vs 96.62%; and 87.62% vs 81.55%, respectively; P < 0.001). On subgroup analyses, sensitivity, specificity, and accuracy of FNB alone were similar to FNA + ROSE [(81.66% vs 86.45%; P = 0.142), (100% vs 100%; P = 1.00) and (88.40% vs 85.43%; P = 0.320]. There were no difference in diagnostic yield of FNB alone vs FNB + ROSE (P > 0.05). Multivariate analysis showed no significant predictor for better accuracy. On subgroup analyses, FNB was superior to FNA for non-pancreatic lesions; however, there was no difference between the techniques among pancreatic lesions. One adverse event was reported in each group. CONCLUSION FNB is superior to FNA with equivalent diagnostic test characteristics compared to FNA + ROSE in the diagnosis of non-pancreatic solid lesions. Our results suggest that EUS-FNB may eliminate the need of ROSE and should be employed as a first-line method in the diagnosis of solid lesions.

    Endoscopic vacuum therapy versus endoscopic stenting for upper gastrointestinal transmural defects: Systematic review and meta-analysis
    (2021) MONTE JUNIOR, Epifanio Silvino do; MOURA, Diogo Turiani Hourneaux de; RIBEIRO, Igor Braga; HATHORN, Kelly Elizabeth; FARIAS, Galileu Ferreira Ayala; TURIANI, Carolina Vaz; MEDEIROS, Flaubert Sena; BERNARDO, Wanderley Marques; MOURA, Eduardo Guimaraes Hourneaux de
    Background: Upper gastrointestinal fistulas, leaks, and perforations represent a high cost burden to health systems worldwide, with high morbidity and mortality rates for affected patients. Management of these transmural defects remains therapeutically challenging. Objectives: The aim of this study is to perform a systematic review and meta-analysis to investigate the efficacy and safety of self-expanding metal stents (SEMS) versus endoscopic vacuum therapy (EVT) for treatment of upper gastrointestinal transmural defects. Methods: Searches were performed on MEDLINE, EMBASE, Central Cochrane, Latin American and Caribbean Health (LILACS), and gray literature, as well as a manual search to identify studies comparing SEMS versus EVT to treat upper gastrointestinal transmural defects. Evaluated outcomes were: rates of successful closure, mortality, length of hospital stay, duration of treatment, and adverse events. Results: Five studies with a total of 274 patients were included. There was a 21% increase in successful fistula closure attributed to EVT compared with the SEMS group (RD 0.21, CI 0.10-0.32; P = 0.0003). EVT demonstrated a 12% reduction in mortality compared to stenting (RD 0.12, CI 0.03-0.21; P = 0.006) and an average reduction of 14.22 days in duration of treatment (CI 8.38-20.07; P < 0.00001). There was a 24% reduction in adverse events (RD 0.24, CI 0.13-0.35; P = 0.0001. There were no statistical differences between the studied therapies regarding the length of hospital stay. Conclusion: Endoscopic vacuum therapy proves to be superior in successful defect closure, mortality, adverse events and duration of treatment.

    Peroral endoscopic myotomy (POEM): a comparative study between Chagasic and idiopathic achalasia
    (2020) FARIAS, Galileu F. A.; MOURA, Diogo T. H. de; MOURA, Eduardo T. H. de; REZENDE, Daniel T. de; HATHORN, Kelly E.; NASI, Ary; QUEIROZ, Natalia S. F.; MOURA, Eduardo G. H. de
    Background and study aims Achalasia can be classified as either primary (idiopathic) achalasia or secondary achalasia, which is a consequence of another systemic disease. Peroral endoscopic myotomy (POEM) is an effective and safe treatment for achalasia. We evaluated the efficacy and safety of POEM in patients with Chagasic achalasia compared to idiopathic achalasia. Patients and methods We evaluated POEM procedures performed at a single institution from November 2016 to January 2018. Demographic data, Eckardt score, lower esophageal sphincter (LES) pressure, body mass index, post-operative erosive esophagitis, adverse events, length of hospital stay, and procedure-related parameters were analyzed. Results Fifty-one patients underwent POEM as a treatment for achalasia in this period (20 patients with Chagasic and 31 with Idiopathic etiology). The overall clinical success rate was 92.1 %, with no statistical difference between groups (90 % in the Chagasic group vs. 93.5 % in the Idiopathic group, P = 0.640). Both groups had significant reduction in Eckardt score and in LES pressure, and increase in bodey mass index (BMI) at 1-year follow-up. There was no statistical difference between groups regarding Eckardt score ( P = 0.439), LES pressure (p = 0.507), BMI ( P = 0.254), post erosive esophagitis (35 % vs. 38.7 %, P = 0.789), adverse events (30 % vs. 12 %, P = 0.163,) length of hospital stay (3.75 days vs. 3.58 days, P = 0.622), and operative time (101.3 min vs. 99.1 min, P = 0.840). Conclusion POEM is an effective and safe treatment for patients with achalasia. There is no difference in POEM outcomes for those patients with Chagasic or Idiopathic achalasia.

    Peroral endoscopic myotomy vs laparoscopic myotomy and partial fundoplication for esophageal achalasia: A single-center randomized controlled trial
    (2022) MOURA, Eduardo Turiani Hourneaux de; JUKEMURA, Jose; RIBEIRO, Igor Braga; FARIAS, Galileu Ferreira Ayala; DELGADO, Aureo Augusto de Almeida; COUTINHO, Lara Meireles Azeredo; MOURA, Diogo Turiani Hourneaux de; SALLUM, Rubens Antonio Aissar; NASI, Ary; SANCHEZ-LUNA, Sergio A.; SAKAI, Paulo; MOURA, Eduardo Guimaraes Hourneaux de
    BACKGROUND Achalasia is a rare benign esophageal motor disorder characterized by incomplete relaxation of the lower esophageal sphincter (LES). The treatment of achalasia is not curative, but rather is aimed at reducing LES pressure. In patients who have failed noninvasive therapy, surgery should be considered. Myotomy with partial fundoplication has been considered the first-line treatment for non-advanced achalasia. Recently, peroral endoscopic myotomy (POEM), a technique that employs the principles of submucosal endoscopy to perform the equivalent of a surgical myotomy, has emerged as a promising minimally invasive technique for the management of this condition. AIM To compare POEM and laparoscopic myotomy and partial fundoplication (LM-PF) regarding their efficacy and outcomes for the treatment of achalasia. METHODS Forty treatment-naive adult patients who had been diagnosed with achalasia based on clinical and manometric criteria (dysphagia score >= II and Eckardt score > 3) were randomized to undergo either LM-PF or POEM. The outcome measures were anesthesia time, procedure time, symptom improvement, reflux esophagitis (as determined with the Gastroesophageal Reflux Disease Questionnaire), barium column height at 1 and 5 min (on a barium esophagogram), pressure at the LES, the occurrence of adverse events (AEs), length of stay (LOS), and quality of life (QoL). RESULTS There were no statistically significant differences between the LM-PF and POEM groups regarding symptom improvement at 1, 6, and 12 mo of follow-up (P = 0.192, P = 0.242, and P = 0.242, respectively). However, the rates of reflux esophagitis at 1, 6, and 12 mo of follow-up were significantly higher in the POEM group (P = 0.014, P < 0.001, and P = 0.002, respectively). There were also no statistical differences regarding the manometry values, the occurrence of AEs, or LOS. Anesthesia time and procedure time were significantly shorter in the POEM group than in the LM-PF group (185.00 +/- 56.89 and 95.70 +/- 30.47 min vs 296.75 +/- 56.13 and 218.75 +/- 50.88 min, respectively; P = 0.001 for both). In the POEM group, there were improvements in all domains of the QoL questionnaire, whereas there were improvements in only three domains in the LM-PF group. CONCLUSION POEM and LM-PF appear to be equally effective in controlling the symptoms of achalasia, shortening LOS, and minimizing AEs. Nevertheless, POEM has the advantage of improving all domains of QoL, and shortening anesthesia and procedure times but with a significantly higher rate of gastroesophageal reflux

    Endoscopic Ultrasound Fine-Needle Aspiration versus Fine-Needle Biopsy for Lymph Node Diagnosis: A Large Multicenter Comparative Analysis
    (2020) MOURA, Diogo Turiani Hourneaux de; MCCARTY, Thomas R.; JIRAPINYO, Pichamol; RIBEIRO, Igor Braga; FARIAS, Galileu Ferreira Ayala; RYOU, Marvin; LEE, Linda S.; THOMPSON, Christopher C.
    Background/Aims: Endoscopic ultrasound fine-needle aspiration (EUS-FNA) is preferred for sampling of lymph nodes (LNs) adjacent to the gastrointestinal wall; however, fine-needle biopsy (FNB) may provide improved diagnostic outcomes. This study aimed to evaluate the comparative efficacy and safety of FNA versus FNB for LN sampling. Methods: This was a multicenter retrospective study of prospectively collected data to evaluate outcomes of EUS-FNA and EUS-FNB for LN sampling. Characteristics analyzed included sensitivity, specificity, accuracy, the number of needle passes, diagnostic adequacy of rapid on-site evaluation (ROSE), cell-block analysis, and adverse events. Results: A total of 209 patients underwent EUS-guided LN sampling. The mean lesion size was 16.22 +/- 8.03 mm, with similar sensitivity and accuracy between FNA and FNB ([67.21% vs. 75.00%, respectively, p=0.216] and [78.80% vs. 83.17%, respectively, p=0.423]). The specificity of FNB was better than that of FNA (100.00% vs. 93.62%, p=0.01). The number of passes required for diagnosis was not different. Abdominal and peri-hepatic LN location demonstrated FNB to have a higher sensitivity (81.08% vs. 64.71%, p=0.031 and 80.95% vs. 58.33%, p=0.023) and accuracy (88.14% vs. 75.29%, p=0.053 and 88.89% vs. 70.49%, p=0.038), respectively. ROSE was a significant predictor for accuracy (odds ratio, 5.16; 95% confidence interval, 1.15-23.08; p=0.032). No adverse events were reported in either cohort. Conclusions: Both EUS-FNA and EUS-FNB are safe for the diagnosis of LNs. EUS-FNB is preferred for abdominal LN sampling. EUS-FNA+ROSE was similar to EUS-FNB alone, showing better diagnosis for EUS-FNB than traditional FNA. While ROSE remained a significant predictor for accuracy, due to its poor availability in most centers, its use may be limited to cases with previous inconclusive diagnoses.
