RESUMEN
INTRODUCTION: The aim of this study was to compare the impact of the depth of myotomy (selective inner layer myotomy (SIM) vs. full-thickness myotomy (FTM)) on the outcome of patients treated with POEM for achalasia. METHODS: This was a retrospective, observational, conducted in two tertiary centers between October 2018 and September 2022. Patients were divided into two groups: SIM and FTM. The primary endpoint was clinical efficacy at 6 months, while secondary endpoints were postoperative criteria (such as pain, length of hospital stay, complications) and occurrence of gastroesophageal reflux disease (GERD) (esophagitis at 6 months, heartburn, and pH-metry). RESULTS: 158 patients were included in the study (33 in the FTM group and 125 in the SIM group). The success rates at 6 and 12 months were similar in both groups, with 84 % and 70 % in the SIM group versus 90 % and 80 % in the FTM group, respectively (p = 0.57 and p = 0.74). However, more opioid analgesics were consumed in the FTM group compared to the SIM group (41% vs 21 %, p < 0.01). The length of hospitalization was longer in the FTM group than in the SIM group (2.17 ± 2.62 vs 2.94 ± 2.33, p < 0.001). The rate of esophagitis at 6 months was comparable (16 % in the SIM group vs 12 % in the FTM group, p = 0.73). There was no significant difference in terms of heartburn at 6 or 12 months between the SIM and FTM groups (18.5% vs 3.8 %, p = 0.07 and 27% vs 12.5 %, p = 0.35, respectively). CONCLUSION: There was no significant difference in terms of clinical efficacy and GERD occurrence between FTM and SIM. However, full-thickness myotomy was associated with more postoperative pain and a longer length of hospital stay. Therefore, selective internal myotomy should be preferred over full-thickness myotomy.

BACKGROUND AND AIMS: Achalasia can be treated very effectively with peroral endoscopic myotomy (POEM), but factors associated with early failure remain to be determined, especially in European cohorts. METHODS: All consecutive adult patients who underwent a first POEM to treat primary achalasia were included in this multicenter retrospective study. Early failure was defined by an Eckardt score (ES) >3 at 3 months after POEM. When evaluating factors predictive of early failure, 2 cohorts were considered: one consisted of the total population, for whom only basic variables were collected, and the other a cohort built for a case-control study that included matched early-failure and early-success patients (ratio, 1:2). RESULTS: Among 746 patients, the early failure rate was 9.4%. Predictive factors were age ≤45 years (P = .019), achalasia types I and III (P < .001), and the development of a severe adverse event during the procedure (P = .023). In the case-control study, the only additional independent risk factor for early failure was a high pre-POEM ES (P = .001). Only the retrosternal pain subscore was significantly associated with the early failure rate. CONCLUSION: The early failure rate of POEM used to treat primary achalasia is <10%. Younger age, type I/III achalasia, and a high pre-POEM ES were significantly associated with failure.

The recent development of per oral endoscopic myotomy (POEM) has been a game changer in the management of patients with achalasia. However, approximately 1 in 10 patients will not experience clinical success. The aim of this mini-review is to describe the current state of knowledge about the risk factors associated with POEM failure for the treatment of achalasia. Suspected risk factors are detailed into pre-, intra-, and post-procedural factors and put into perspective. Pre-procedural factors have been described, such as pre-treatment Eckardt score, previous treatments for achalasia, sigmoid type esophagus, significant esophageal dilatation, non-type II achalasia, young age and long duration of symptoms. An intra-procedural factor, mucosal injury during POEM, has also been associated with POEM failure. The occurrence of post-POEM GERD was identified as a controversial post-procedural factor associated with failure. The presumed mechanisms of POEM failure are incomplete myotomy or ineffective LES disruption, as confirmed by high-resolution manometry. However, when manometry confirms a significant decrease in LES pressure, it is likely that either impaired peristalsis or a morphologic abnormality such as extreme esophageal dilatation or severe tortuosity, which are not treated by POEM, should be suspected. Notably, a recently described adverse effect of POEM is the formation of a pseudo-diverticulum at the site of the myotomy (blown out myotomy). We finally stress the importance of performing a complete workup in case of POEM failure as different mechanisms of POEM failure should lead to different management.
RESUMEN
BACKGROUND: In France, it is mandatory that gastroenterology fellows have mastered the basic level of endoscopy by the end of training. The aim of this study was to assess improvement in the quality of fellows' endoscopy training in France during the last four years. METHODS: All fellows in France in training were eligible for participation. A 21-item questionnaire was sent out. The primary outcome was the completion by fourth year fellows of all the number of procedures recommended. Results were compared with those of a 2016 survey. RESULTS: Two-hundred-and-sixty-five fellows responded to the survey. The participation rate was 47.0%. The mean age was 27.3 ± 1.0 years and 56.4% were female. Access to theoretical courses (63.7% vs. 30.6%, p < 0.001) and simulation-based training (virtual reality simulator: 58.4% vs. 28.2%, p < 0.001, animal models: 29.4% vs. 17.2%, p < 0.001) was significantly higher in 2020. Although the number of procedures did not increase, significantly higher perception of skill acquisition in colonoscopy as well as diminished pressure to advance procedures were noted. CONCLUSION: Access to theoretical courses and simulation-based training and perceived acquisition of numerous skills has gotten better. However, the quality of training in endoscopy still needs improvement.

BACKGROUND: The low FODMAPs (fermentable oligo-, di-, monosaccharides, and polyols) diet improves lower gastrointestinal symptoms. Patients suffering from proton pump inhibitor (PPI) refractory gastroesophageal reflux disease (GERD) have limited treatment options. We investigated the efficacy of a low FODMAPs diet in patients with PPI refractory GERD. METHODS: This multicenter, randomized, open-label study compared the efficacy of a 4-week low FODMAPs diet and usual dietary advice (ie, low-fat diet and head of bed elevation) in patients with symptomatic PPI refractory GERD, defined by a Reflux Disease Questionnaire (RDQ) score >3 and abnormal pH-impedance monitoring on PPIs. The primary endpoint was the percentage of responders (RDQ ≤3) at the end of the diet. RESULTS: Thirty-one patients (55% women, median age 45 years) were included, 16 randomized in the low FODMAPs diet group and 15 in the usual dietary advice group. Adherence to the assigned diet was good, with a significant difference in the FODMAPs intake per day between the low FODMAPs diet (2.5 g) and the usual dietary advice group (13 g) (p < 0.001). There was no difference in response rates (RDQ score ≤3) between the low FODMAPs diet (6/16, 37.5%) and usual dietary advice (3/15, 20%) groups (p = 0.43). Total RDQ score and dyspepsia subscore decreased significantly over time in both groups (p = 0.002), with no difference according to the assigned diet group (p = 0.85). CONCLUSION: Low FODMAPs diet and usual dietary advice have similar but limited beneficial effects on symptoms in patients with PPI refractory GERD.
