RESUMO
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 92.1â%, with no statistical difference between groups (90â% in the Chagasic group vs. 93.5â% in the Idiopathic group, P â=â0.640). Both groups had significant reduction in Eckardt score and in LES pressure, and increase in bodey mass index (BMI) at 1-year follow-up.âThere was no statistical difference between groups regarding Eckardt score ( P â=â0.439), LES pressure (pâ=â0.507), BMI ( P â=â0.254), post erosive esophagitis (35â% vs. 38.7â%, P â=â0.789), adverse events (30â% vs. 12â%, P â=â0.163,) length of hospital stay (3.75 days vs. 3.58 days, P â=â0.622), and operative time (101.3âmin vs. 99.1âmin, P â=â0.840). 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.
RESUMO
BACKGROUND: Per-oral endoscopic myotomy (POEM) has become the preferred alternative treatment to standard Heller myotomy for patients with esophageal achalasia, in Latin American countries. The aim of our study was to evaluate the efficacy and safety of a POEM in the management of achalasia with and without Chagas disease in patients receiving POEM. METHODS: Patients who underwent POEM from tertiary centers in Latin America were included in a dedicated registry. Countries included Brazil, Colombia, Ecuador, Mexico, Nicaragua, and Venezuela. Patients enrolled needed to have a preoperative manometry and swallow contrast study confirming achalasia. Clinical success was defined as significant improvement in Eckardt score after therapy. RESULTS: POEM was technically successful in 81/89 (91%) patients (mean age, 44 y). There was a significant decrease in preprocedure and postprocedure Eckardt score from 8.7 (range, 3 to 12) to 2.15 (0 to 10) (P<0.001), preprocedure and postprocedure barium swallow evaluation (98% vs. 89%; P=0.017), and preprocedure and postprocedure lower esophageal sphincter pressure measurement (from 35 to 13.8 mm Hg; P<0.001). Clinical success was achieved in 93% of patients. Patients with Chagas disease (n=58) were 9.5 times more likely to respond to POEM (P=0.0020; odds ratio, 9.5). CONCLUSIONS: POEM is an efficacious and safe therapeutic modality for treatment of achalasia in Latin America. Chagas disease-related achalasia seems to particularly respond better to POEM when it is performed by experienced endoscopists.

OBJECTIVES: The aim of the study was to evaluate the role of early endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of acute biliary pancreatitis, in comparison with conservative treatment. METHODS: Systematic review via databases (MEDLINE [PubMed], Latin-American and Caribbean Health Sciences Literature database, Embase, Cochrane Central, and the [Brazilian] Regional Library of Medicine) is conducted. We analyzed 10 randomized controlled trials (1091 patients). Outcomes were the following: local and systemic adverse events; acute cholangitis; death; length of hospital stay; cost; abdominal pain; and time to a reduction in body temperature. For the meta-analysis, we used risk difference (RD) and mean with standard deviation as measures of variability. RESULTS: There was a statistically significant difference between the patients submitted to ERCP in terms of the following: local adverse events (RD, 0.74; 95% confidence interval [CI], 0.55-0.99), time to pain relief and time to a reduction in axillary temperature (RD, -5.01; 95% CI, -6.98 to -3.04, and RD, -1.70; 95 CI%, -2.33 to -1.08, respectively). Patients undergoing ERCP spent less time in hospital (RD, -11.04; 95% CI, -15.15 to -6.93). Cost was lower in the group treated with ERCP. CONCLUSIONS: Early ERCP decreases local adverse events, shortening the time to pain relief, to a reduction in axillary temperature, hospital stays, and cost in patients with acute biliary pancreatitis.

Objective: Through this systematic review and meta-analysis, we aim to clarify the differences between these two techniques, thus improving primary success cannulation and reducing complications during endoscopic retrograde cholangiopancreatography, primarily pancreatitis. Methods: A comprehensive search was conducted to search for data available up until June2015from the most important databases available in the health field: EMBASE, MEDLINE (via PubMed), Cochrane, LILACS and CENTRAL (via BVS), SCOPUS, the CAPES database (Brazil), and gray literature. Results: Nine randomized clinical trialsincluding2583 people were selected from20,198 studies for meta-analysis. Choledocholithiasis had been diagnosed in mostly (63.8%) of the patients, who were aged an average of 63.15 years. In those patients treated using the guide wire-assisted cannulation technique, provided a significantly lower instance of pancreatitis (RD=0.03; 95% CI: 0.01-0.05; I2= 45%) and greater primary success cannulation (RD=0.07; 95% CI: 0.03-0.12; I2=12%) than conventional contrast cannulation. Conclusions: The guide wire-assisted technique, when compared to the conventional contrast technique, reduces the risk of pancreatitis and increases primary success cannulation rate. Thus, guide wire-assisted cannulation appears to be the most appropriate first-line cannulation technique
Objetivo: A través de esta revisión sistemática y meta-análisis, nuestro objetivo es aclarar las diferencias entre estas dos técnicas, mejorando así la canulación de éxito primario y reducir las complicaciones durante la colangiopancreatografía retrógrada endoscópica, principalmente la pancreatitis. Métodos: Una búsqueda exhaustiva se realizó para buscar datos disponibles hasta junio de 2015, desde las bases de datos más importantes disponibles en el campo de la salud: EMBASE, MEDLINE (vía PubMed), Cochrane, LILACS y CENTRAL (a través de la BVS), SCOPUS, la base de datos CAPES (Brasil), y la literatura gris. Resultados: Nueve ensayos clínicos aleatorios incluyendo 2583 personas fueron seleccionados de 20198 estudios de meta- análisis. Coledocolitiasis había sido diagnosticada en su mayoría (63,8%) de los pacientes, que tenían entre un promedio de 63,15 años. En los pacientes tratados con la técnica de canulación guiada, proporcionado una instancia significativamente menor de pancreatitis (RD=0,03; IC del 95%: 0,01-0,05; I2=45%) y una mayor canalización de éxito primario (RD=0,07; IC del 95%: 0,03-0.12; I2=12%) que la canulación por contraste. Conclusiones: La técnica canulación con alambre guía, en comparación a la técnica de contraste convencional, reduce el riesgo de pancreatitis y aumenta la tasa de canulación con éxito primario. Por lo tanto, canulación con alambre guía parece ser la técnica de canulación de primera línea y la más adecuada

INTRODUCTION: Roux-en-Y gastric bypass is a commonly used technique of bariatric surgery. One of the most important complications is gastrojejunal anastomotic stricture. Endoscopic balloon dilation appears to be well tolerated and effective, but well-designed randomized, controlled trials have not yet been conducted. OBJECTIVE: Identify factors associated with complications or failure of endoscopic balloon dilation of anastomotic stricture secondary to Roux-en-Y gastric bypass surgery. SETTING: Gastrointestinal endoscopy service, university hospital, Brazil. METHODS: The records of 64 patients with anastomotic stricture submitted to endoscopic dilation with hydrostatic balloon dilation were reviewed. Information was collected on gastric pouch length, anastomosis diameter before dilation, number of dilation sessions, balloon diameter at each session, anastomosis diameter after the last dilation session, presence of postsurgical complications, endoscopic complications, and outcome of dilation. Comparisons were made among postsurgical and endoscopic complications; number of dilations, balloon diameter; anastomosis diameter before dilation; and dilation outcome. RESULTS: Success of dilation treatment was 95%. Perforation was positively and significantly associated with the number of dilation sessions (P = .03). Highly significant associations were found between ischemic segment and perforation (P<.001) and between ischemic segment and bleeding (P = .047). Ischemic segment (P = .02) and fistula (P = .032) were also associated with dilation failure. CONCLUSION: Ischemic segment and fistula were found to be important risk factors for balloon dilation failure. The greater the number of dilation sessions, the greater the number of endoscopic complications.

BACKGROUND: Among the possible complications of bariatric surgery, fistula and partial dehiscence of the gastric suture are well known. Reoperation often is required but results in significant morbidity. Endoscopic treatment of some bariatric complications is feasible and efficient. METHODS: A modified metallic stent was placed between the gastroaesophageal junction and the alimentary jejunal limb, allowing the passage of a nasoenteric feeding tube into the jejunal limb. RESULTS: Endoscopy showed disruption of nearly the entire staple line at the gastric pouch. The modified stent was placed and allowed wound healing. After 31 days, the stent had migrated and was removed endoscopically. Total closure of the fistula was reported 30 days afterward. CONCLUSIONS: Endoscopic treatment of some bariatric surgery complications is feasible and has been reported previously. This report presents a case of a serious leakage treated by placement of a self-expandable metal stent to bridge the fistula.
