RESUMO

Introduction: The diagnostic yield (DY) of small-bowel capsule endoscopy (SBCE) varies considerably according to its indication. Some strategies have been used to increase DY with varying results. The intention of this study was to identify whether evaluation of the SBCE recordings by a second reviewer can increase DY and change patient management. Methods: One hundred SBCEs with different indications, already read by an endoscopist were read by a second blinded endoscopist. When the results of the 2 readings were different, the images were discussed by the endoscopists; if no consensus was reached, they took the opinion of a third endoscopist into account. All the participating endoscopists had experience in reading SBCEs (i.e., >50 per year). The SBCE findings were divided into positive (vascular lesions, ulcers, and tumors), equivocal (erosions or red spots), and negative. The interobserver agreement and the increase in DY were assessed as well as the percentage of false-negatives (FNs) in the first evaluation. Results: The indications for SBCE were small-bowel bleeding (SBB) in 48 cases, Crohn's disease (CD) in 30, and other causes (iron-deficiency anemia, small-bowel tumors, and diarrhea) in 22. There was substantial interobserver agreement between evaluations (κ = 0.79). The findings in the first evaluation were positive in 60%, equivocal in 20% and, negative in 20%. In the second evaluation, 66% were positive, 18% were equivocal, and 16% were negative. The increase in DY with the second reading was 6% (p = 0.380), i.e., 6.3% for SBB, 4.4% for CD and 9.2% for other indications, resulting in a change in management of 4% of the patients. FNs in the first SBCE reading were found in 4% of the SBCEs. Discussion: A second evaluation of the SBCE recordings identified significant pathology that the first evaluation had missed, resulting in a nonsignificant 6% increase in DY and a change in the management of 4% of the patients.


Introdução: O rendimento diagnóstico (DY) da enteroscopia por cápsula (SBCE) varia consideravelmente de acordo com as suas indicações. Foram estudadas algumas estratégias para melhorar o DY, com resultados variados. O objetivo deste estudo é avaliar se uma segunda leitura de registos de enteroscopia por cápsula por um segundo endoscopista pode melhorar o DY e alterar o manejo dos doentes. Métodos: 100 SBCE realizadas por indicações variadas, previamente avaliadas por um endoscopista, foram reavaliadas por um segundo endoscopista cego para a primeira leitura. Na presença de resultados discordantes nas 2 leituras, as imagens foram discutidas pelos 2 endoscopistas, e por um terceiro na ausência de consenso entre os 2 primeiros. Todos os endoscopistas são experientes na leitura de SBCE (>50 SBCE/ano). Os achados foram categorizados em positivos (lesões vasculares, úlceras e tumores), equívocos (erosões e pontos vermelhos) e negativos. Foi avaliada a concordância inter-observador e o aumento do DY, bem como a percentagem de falsos negativos da primeira avaliação. Resultados: As indicações para SBCE foram hemorragia do intestino delgado (SBB) em 48 casos, doença de Crohn (CD) em 30 e outras causas (anemia por défice de ferro, pesquisa de tumores do intestino delgado e diarreia) em 22. A concordância inter-observador foi substancial (k = 0.79). Os achados da primeira avaliação foram positivos em 60%, equívocos em 20% e negativos em 20%, enquanto na segunda avaliação foram positivos em 66%, equívocos em 18% e negativos em 16%. O aumento de DY foi de 6% com a segunda leitura (p = 0.38), sendo 6.3% para SBB, 4.4% para CD e 9.2% para outras indicações, resultando numa alteração no manejo de 4% dos doentes. Foram identificados falsos negativos na primeira avaliação em 4% das SBCE. Conclusão: A segunda avaliação dos registos de SBCE identificou patologia significativa previamente não identificada, resultando num aumento não significativo de 6% do DY e numa alteração no manejo de 4% dos doentes.

RESUMO

BACKGROUND AND AIMS: Gastric peroral endoscopic myotomy (G-POEM) is used for refractory gastroparesis (RG) with good early-term but variable mid- and long-term outcomes. Limited data exist about candidates and long-term clinical and predictive factors. Our aim was to evaluate the 4-year follow-up efficacy and predictive factors in patients with RG. METHODS: Confirmed RG patients were included and evaluated between April 2017 and December 2021. Gastroparesis Cardinal Symptom Index (GCSI) score, retention percentage at 4 hours (RP4H), mean half-emptying time (MHET), and the 36-item short-form survey (SF-36) were performed at 1, 6, 12, 18, 24, 30, 36, 42, and 48 months. RESULTS: After G-POEM, 374 patients with RG were included: 141 patients (37.7%) had diabetic gastroparesis (DG), 115 (30.7%) had idiopathic gastroparesis (IG), 102 (27.3%) had postsurgical gastroparesis (PSG), and 16 (4.3%) had other etiologies. After the 48-month evaluation, 102 patients completed follow-up (DG, 58; IG, 22; PSG, 18; other, 4). Before G-POEM, GCSI score, RP4H, and MHET were 3.84 ± .53, 44% (interquartile range [IQR], 11-68), and 246 minutes (IQR, 150-368), respectively, and after the 48-month evaluation improved to 2.1 ± .70 (P < .001), 15.5% (IQR, 0-36; P = .021), and 135 minutes (IQR, 67-290; P = .045), respectively. At the 48-month evaluation, clinical success was 77.5%. DG showed the best outcomes (DG vs IG vs PSG vs other: 86.5% vs 72.5% [P = .001] vs 72.1% [P = .003] vs 68.8% [P < .001]). Long-term success predictors were DG (odds ratio [OR], 5.113; 95% confidence interval [CI], 1.643-5.981; P = .035), early diagnosis (OR, 2.455; 95% CI, 1.129-3.522; P = .042), nausea/vomiting (OR, 3.541; 95% CI, 1.881-5.511; P = .012), GCSI score at 6 months (1.5-2) (OR, 3.612; 95% CI, 2.122-5.317; P = .022), and RP4H <10% at 6 months (OR, 2.188; 95% CI, 1.435-4.233; P = .039). CONCLUSIONS: G-POEM is an effective 4-year treatment in patients with RG, especially in DG, establishing a potential first-line therapy in these patients. However, randomized controlled clinical trials are needed to confirm these results. (Clinical trial registration number: NTC03126513.).

RESUMO

Backgrounds and study aims Treatment of octogenarian patients with achalasia with conventional treatments is effective but with compromised safety. Biodegradable stents (BS) are promising. We aimed to evaluate their safety, efficacy and clinical outcomes at early, mid and long-term in this population. Patients and methods Naïve or previously-treated achalasic octogenarian patients underwent to BS placement (BSP) between December, 2010 and November, 2011, and were followed-up for 9-years. A strict follow-up was performed. Results Thirty-two patients were included, (17 men [53.1 %]; median age 82 years [78-92]). BSP was performed in all patients. At 9y, 18/32 (56.2 %) completed protocol. Mean BSP time was 37.5±12.1 min and 34.4 % presented thoracic pain. At 1 m, six BS were migrated (18.7 %), requiring a second BSP fixed with hemoclips. At 3 m, twenty-three (72.8 %) completed degradation process. At 6 m, eighteen (56.2 %) presented clinical dysphagia, of whom 5/32 (15.6 %) presented stenotic-tissue hyperplasia, responding to balloon dilation in all cases. Pre-BSP Eckardt, Timed barium esophagram and integrated relaxation pressure improved post-BSP 6 m values (9 vs 2, p = 0.001; < 50 % = 93.8 % vs > 80 % = 81.5 %, p = 0.003 and 18.8 ±â€Š3.2 vs 11.1 ±â€Š2.6 mmHg, p = 0.001, respectively), and there were no significant changes up to 9y post-BSP. Esophagitis grade A or B was presented between 4.7 % to 11.2 % and controlled with PPI. After 9 years we had clinical success rates of 94.4 %, 72 %, and 65.4 % for time point evaluation, per protocol and intention to treat analysis, respectively. Conclusions BSP represents a feasible alternative option in octogenarian patients with achalasia who are high risk with other treatments, presenting acceptable early, mid-, and long-term outcomes.

RESUMO

BACKGROUND: Third-space endoscopy is a novel, safe, and effective method for treating different gastrointestinal conditions. However, several failed endoscopic procedures are attributed to incomplete myotomy. Lighting devices are used to prevent organic injuries. We aimed to investigate the feasibility of using a hand-made LED-probe (LP) in third-space procedures. METHODS: This prospective study was conducted in a tertiary-care center in Mexico between December 2016 and January 2019. We included peroral endoscopic myotomy (POEM) and gastric peroral endoscopic myotomy(G-POEM) procedures. Pseudoachalasia, peptic ulcer, normal gastric emptying scintigraphy (GES) and prepyloric tumors were excluded. LP was used to guide or confirm procedures. Clinical and procedural characteristics were recorded and analyzed. RESULTS: Seventy third-space procedures were included (42POEM,28G-POEM), with an average patient age of 46.7 ± 14.3 and 43.7 ± 10.1 years, respectively. For the POEM and G-POEM groups, respectively, 18/42(42.9%) and 13/28(46.7%) patients were males; median procedure times were 50 (interquartile range [IQR]: 38-71) and 60(IQR: 48-77) min, median LP placement times were 5(IQR: 4-6) and 6(IQR: 5-7) min, mild adverse events occurred in 4(9.4%) and 4(14.2%) of cases, and clinical success at 6 months occurred in 100 and 85.7% of cases. Integrated relaxation pressure (IRP) improved from 27.3 ± 10.8 to 9.5 ± 4.1 mmHg (p < 0.001); retention percentage at 4 h also improved. LP was successfully placed and adequate myotomy confirmed including 14.2 and 17.8% of POEM and G-POEM difficult patients. CONCLUSIONS: Using an LP is promising and allows guiding during third-space procedures either for submucosal tunnel creation or myotomy confirmation, with excellent safety and efficacy in clinical practice.

RESUMO

BACKGROUNDS AND AIMS: New mucosal resective and ablative endoscopic procedures based on gastric cardiac remodeling to prevent reflux have appeared. We aimed to evaluate the feasibility of a new ablative technique named antireflux ablation therapy (ARAT) for control of GERD in patients without hiatal hernia. METHODS: Patients with proton pump inhibitor (PPI)-refractory GERD without hiatal hernia underwent ARAT between January 2016 and October 2019. Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL), upper endoscopy, 24-hour pH monitoring, and PPI use were documented at 3, 6, 12, 24, and 36 months after ARAT. RESULTS: One hundred eight patients were included (61 men [56.5%]; median age, 36.5 years; range, 18-78 years). ARAT was performed on all patients. At the 36-month evaluation, 84 patients had completed the protocol. Median ARAT time was 35.5 minutes (range, 22-51 minutes), and median circumference ablation was 300° (range, 270°-320°). No major adverse events occurred, and 14 of 108 patients (12.9%) presented with stenosis that was responsive to balloon dilation (<5 sessions). At the 3-month evaluation, the acid exposure time (AET), DeMeester score, and GERD-HRQL score had decreased from 18.8% to 2.8% (P = .001), 42.5 to 9.1 (P = .001), and 36.5 to 10 (P = .02), respectively, and these values were maintained up to 36 months. Success (AET <4%) was achieved in 89% and 72.2% at 3 and 36 months, respectively. Related factors at 36 months were as follows: pre-ARAT Hill type II (odds ratio [OR], 3.212; 95% confidence interval [CI], 1.431-5.951; P = .033), post-ARAT 3-month Hill type I (OR, 4.101; 95% CI, 1.812-9.121; P = .042), and AET <4% at 3 months (OR, 5.512; 95% CI, 1.451-7.621; P = .021). CONCLUSIONS: ARAT is a feasible, safe, and effective therapy for early and mid-term treatment of GERD in patients without a sliding hiatal hernia. However, longer follow-up evaluations and randomized comparative studies are needed to clarify its real role. (Clinical trial registration number: NCT03548298.).

RESUMO

BACKGROUND: new alternatives for entry site closure (ESC) in per-oral endoscopy myotomy (POEM) and gastric peroral endoscopy myotomy (G-POEM) have appeared. OBJECTIVE: to compare the over-the-scope-clip (OTSC®) and conventional clips (CC) for ESC in POEM and G-POEM. MATERIAL AND METHODS: a retrospective review of a prospective POEM and G-POEM database was performed between January 2015 and August 2019. A description was made of outcomes, using either OTSC® or CC for submucosal tunnel closure. RESULTS: forty-six POEM and 26 G-POEM were included in the study (23/13 per group [CC/OTSC®]). There were no clinical or procedure differences. ESC was performed with 1 OTSC® vs 5 CC and 1 vs 6 (p = 0.01) for POEM and G-POEM, respectively. Adverse events associated with clips were 21.7% vs 13% (p = 0.01) and 7.7% vs 0% (p = 0.02) for CC and OTSC® in POEM and G-POEM, respectively. CONCLUSION: OTSC® represents a safe and effective alternative for entry site closure in POEM and G-POEM cases. Further studies are needed to recommend OTSC® as the first option for submucosal tunnel closure in these procedures.

RESUMO

BACKGROUND: Peroral endoscopic myotomy (POEM) is a recognized technique for patients with achalasia. We aimed to evaluate the feasibility of using a small-caliber endoscope (thin-POEM) to perform POEM in patients with achalasia. METHODS: Naïve or previously treated patients were included between February 2016 and April 2018. A small-caliber (5.9 mm) nasoendoscope was used, with a modified closure method using cyanoacrylate. Strict follow-up was performed. RESULTS: 45 patients were included, aged 45.5 years (interquartile range [IQR] 22 - 69); 53 % (24/45) had type II achalasia. Median total time for thin-POEM was 54 minutes (IQR 37 - 77) and median myotomy length was 13.5 cm (IQR 6 - 20). Results pre-procedure and 3 months post were Eckardt score 10 vs. 1 (P < 0.001), integrated relaxation pressure (IRP) 25.3 vs. 8.5 mmHg (P < 0.001), and timed barium esophagram (TBE) 100 % severely delayed vs. 86 % normal (P < 0.001), respectively. Type III patients had the longest thin-POEM times (median 58 minutes [IQR 52 - 77]). Reflux was confirmed at 3 months clinically in 17 % of patients, endoscopically in 20 %, and on pH monitoring in 53 %. At 6 months and 12 months, 40 % and 33 % of patients remained positive on pH monitoring and were medically managed. CONCLUSIONS: Thin-POEM seems to be a safe, effective, and efficient procedure for POEM in patients with achalasia, with good short-term follow-up results.

RESUMO

Background and study aims Peroral endoscopic myotomy (POEM) is an excellent endoscopic treatment for achalasia. Clinical and manometric parameters are used for evaluation and follow-up. However, clinical success does not guarantee high quality of life (QoL) scores, generating doubts about their direct relationship. We aimed to evaluate QoL scores before and after POEM at medium and long term, to evaluate differences between achalasia subtypes and find which factors related to low QoL scores. Patients and methods Achalasia-confirmed patients undergoing POEM between February 2012 and November 2016. and completing at least 1 year of follow-up, were included. Assessment before and at 1, 6, 12, 24, 36 and 48 months after POEM employed manometry, barium series, Eckardt score, and the AE-18 health-related QoL scale. Demographic, clinical, and procedure characteristics were documented, with comparisons between subgroups. Multiple logistic regression analysis was done. Results 65 of 88 patients were included (38 women, 27 men; median age 47 years, interquartile range [IQR] 20 - 81), and 50 (76.9 %) completed 4 years of follow-up. Eckardt score improved (median, preprocedure 10 vs. post-procedure 2; P = 0.002) and this persisted. There was initial improvement in median integrated relaxation pressure (IRP) (29.4 mmHg [16 - 55] vs. 10.3 mmHg [3 - 18]; P = 0.000) and median QoL scores (40 vs. 68 at 1 month; P = 0.002); however IRP increased and QoL scores decreased. Men with confirmed type III achalasia had low QoL scores. Conclusions All patients had significant clinical improvement after POEM, with medium- to long-term persistence. Though quality of life and IRP initially improved, they deteriorated in the long term. Male sex and type III achalasia seem to be associated with low QoL scores.

RESUMO

Resumen: Introducción: Hemospray® es un nuevo dispositivo para hemostasia endoscópica utilizado para el sangrado gastrointestinal no variceal. Permite la hemostasia mediante la activación plaquetaria y el aumento de la concentración de factores de coagulación, así como la formación de una barrera mecánica sobre la pared de un vaso sangrante creando un tapón mecánico en el sitio de sangrado. Dentro de las principales indicaciones para su uso se encuentran lesiones de difícil acceso endoscópico, hemorragia gastrointestinal masiva, múltiples sitios de sangrado, modificación de la anatomía por terapia endoscópica previa, presencia de coagulopatía, dificultad para tener visualización directa o cuando es imposible tener contacto con la lesión sangrante. Sin embargo, su uso en niños aún no ha sido aprobado por la FDA. Existe un caso publicado de un paciente de 11 meses tratado exitosamente con Hemospray® por hemorragia gastrointestinal no variceal. Caso clínico: Se reporta el caso de una paciente de 2 años con falla hepática aguda y cirrosis biliar primaria con hipertensión portal y sangrado post-escleroterapia. Se analizó el caso para sustentar las nuevas terapias para el control del sangrado masivo en úlceras post-escleroterapia. Conclusiones: La aplicación demostró ser segura y sin efectos adversos. El uso de Hemospray® es una alternativa efectiva en el control del sangrado gastrointestinal.


Abstract: Background: Hemospray® is a new device for endoscopic hemostasis used for non-variceal gastrointestinal bleeding. It enables hemostasis and platelet activation by increasing the concentration of clotting factors and forming a mechanical barrier on the wall of a bleeding vessel creating a mechanical plug at the site of bleeding. Within the main indications for use are: injuries with difficult endoscopic access, massive gastrointestinal bleeding, multiple bleeding sites, modification of the anatomy by previous endoscopic therapy, presence of coagulopathy, difficulty in having direct visualization or when it is impossible to have contact with the bleeding lesion. However, its use in children has not been approved yet by the FDA. There is a case report of an 11-month-old patient successfully treated with Hemospray® for non-variceal gastrointestinal bleeding. Clinical case: We report the case of a 2-year-old female with acute liver failure and primary biliary cirrhosis with portal hypertension and bleeding after sclerotherapy. We analyzed the case to support new therapies for massive bleeding control in post-sclerotherapy esophageal ulcers. Conclusions: The application showed to be safe without side effects. Using Hemospray® is an effective alternative in controlling gastrointestinal bleeding.

RESUMO

BACKGROUND AND STUDY AIM: Per oral endoscopic myotomy (POEM) is a complex technique used in achalasia. Preclinical training is essential but little is known about the number of procedures needed. The aim of this study was to determine the number of procedures required to master POEM in an animal model. PATIENTS AND METHODS: This prospective comparative study was conducted in two swine models at a single institution in Mexico City between November 2012 and October 2014: Group 1 (G1) = 30 ex vivo and Group 2 (G2) = 20 live swine models. POEM was mastered after finishing the five steps without complications. Time, characteristics, and complications were recorded. Velocity of tunnelization and myotomy (VTM) was determined. Ex vivo analysis was done in G1 immediately after finishing POEM and at day 30 in G2. RESULTS: A total of 50 POEM were done in both groups (G1 = 30, G2 = 20). The mean times were 90.17 min (G1) and 89.50 min (G2) (P = 0.92). Myotomy was faster in G2 (21.10 vs 27.97 min; P = 0.009) with a slightly slower tunnelization (40.35 vs 41.13 min; P = 0.86). Myotomy was longer in G2 (9.25 vs 8.83 cm; P = 0.26). VTM between the groups was similar (G1 = 0.159 vs G2 = 0.157 cm/min; P = 0.925). Complications were: mucosotomy (G1 = 18 %, G2 = 8 %; P = 0.430), mediastinal perforation (G1 = 12 %, G2 = 8 %; P = 1.0), and perforation at the gastroesophageal junction (GEJ) level (G1 = 16 %, G2 = 4 %; P = 0.149). Seven models in G2 presented minor bleeding and there was one death not attributed to the procedure. Mastery was obtained after 26 cases. CONCLUSIONS: We suggest that centers interested in learning POEM consider 26 procedures in animal models to master it before performing it in patients with achalasia.
