RESUMO
OBJECTIVE: Sphincter of Oddi dysfunction (SOD) has been used to describe patients with RUQ abdominal pain without an etiology. We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of ES (endoscopic sphincterotomy) for SOD. METHODS: The study methodology follows the PRISMA guidelines. A comprehensive search was conducted using MEDLINE and EMBASE databases for RCTs with ES in patients with SOD. The primary outcome assessed was the improvement of abdominal pain after ES/sham. A random effects model was used to calculate pooled estimates for each outcome of interest. RESULTS: Of the initial 55 studies, 23 were screened and thoroughly reviewed. The final analysis included 3 studies. 340 patients (89.7% women) with SOD were included. All patients had a cholecystectomy. Most included patients had SOD type II and III. The pooled rate of technical success of ERCP was 100%. The average clinical success rate was 50%. The pooled cumulative rate of overall AEs related to all ERCP procedures was 14.6%. In the sensitivity analysis, only one study significantly affected the outcome or the heterogeneity. CONCLUSION: ES appears no better than placebo in patients with SOD type III. Sphincterotomy could be considered in patients with SOD type II and elevated SO basal pressure.

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
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 [53.1â%]; median age 82 years [78-92]). BSP was performed in all patients. At 9y, 18/32 (56.2â%) completed protocol. Mean BSP time was 37.5±12.1âmin and 34.4â% presented thoracic pain. At 1âm, six BS were migrated (18.7â%), requiring a second BSP fixed with hemoclips. At 3âm, twenty-three (72.8â%) completed degradation process. At 6âm, eighteen (56.2â%) presented clinical dysphagia, of whom 5/32 (15.6â%) presented stenotic-tissue hyperplasia, responding to balloon dilation in all cases. Pre-BSP Eckardt, Timed barium esophagram and integrated relaxation pressure improved post-BSP 6âm values (9 vs 2, pâ=â0.001; <â50â%â=â93.8â% vs >â80â%â=â81.5â%, pâ=â0.003 and 18.8â±â3.2 vs 11.1â±â2.6âmmHg, pâ=â0.001, respectively), and there were no significant changes up to 9y post-BSP. Esophagitis grade A or B was presented between 4.7â% to 11.2â% and controlled with PPI. After 9 years we had clinical success rates of 94.4â%, 72â%, and 65.4â% 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
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.).

INTRODUCTION: Disconnected pancreatic duct syndrome (DPDS) is defined as the complete disruption of the main pancreatic duct, the result are peripancreatic fluid collections or pancreatic leaks. The aim of this study was to report the results of derivative endoscopic treatment of DPDS in a long-term follow-up period. PATIENTS AND METHODS: We performed a retrospective analysis of prospectively collected data. Endoscopic treatment consisted of transmural drainage with 2 double pigtail plastic stents (7 F and 4 cm) deployed under endoscopic ultrasound guidance. RESULTS: In total, 21 patients were included in our study. There were 15 (71%) men and the median age was 36 years (range, 23 to 86 y). The principal etiology of DPDS was acute pancreatitis. A total of 20 (95.2%) patients were diagnosed with DPDS by endoscopic pancreatography and only 1 (4.8%) patient by magnetic resonance cholangiopancreatography (MRCP). The median follow-up time was 28 months (range, 7 to 76 mo). Technique success was 100% and initial clinical success was 80.9% (17/21). Three (17.6%) of these patients required a new endoscopic procedure with success in all cases. During follow-up, 11 (52%) patients developed diabetes mellitus and 3 patients (14%) developed exocrine pancreatic insufficiency. There were 5 (15%) patients with complications. CONCLUSION: According to our data, endoscopic treatment with the placement of a permanent indwelling transmural stents is a useful and safe tool for the treatment of DPDS.

BACKGROUND AND AIM: To compare the efficacy and tolerability of a low-volume (2-L) polyethylene glycol (PEG) regimen for colonoscopy compared to single (4-L) or split-dose (2-L + 2-L) regimens. METHODS: In-hospital patients who were candidates for colonoscopy were randomly assigned to: group 1 single-dose (PEG 4 L the day before the study, n = 60); group 2: split-dose (2 L the day before and 2 L on the day of the procedure, n = 61); and group 3: low-volume 2-L PEG solution (the day of the procedure, n = 59). A blinded evaluation of the quality of colonic preparation was assessed by the Boston bowel preparation scale. RESULTS: Satisfactory bowel preparation of the right colon was more frequently reported for group 3 than for group 1 (70% vs 53%, P = 0.045), in the transverse colon it was 82% versus 69% (P = 0.032), and on the left side of the colon it was 80% versus 67.7% (P = 0.028). Compared to group 2, satisfactory bowel preparation in group 3 was similar in the transverse colon and left colon. Nausea, vomiting, and abdominal discomfort were less frequent in patients of group 3. Patients in group 3 had fewer sleep disorders and fewer hours of sleep loss compared to patients in the other groups. CONCLUSIONS: Preparation with 2 L caused less abdominal discomfort and fewer sleep disorders. The split dose had a better quality of preparation in the right colon. Both preparations were clearly better than the 4-L preparation.
