RESUMO
BACKGROUND AND AIMS: Gastric emptying scintigraphy (GES) is the criterion standard for the diagnosis of gastroparesis. However, data are lacking regarding the prognostic value of preoperative intragastric meal distribution during GES in patients undergoing gastric peroral endoscopic myotomy (G-POEM) for gastroparesis. This study investigated the association of GES morphologic parameters and the long-term clinical success of G-POEM. METHODS: This retrospective study included patients who underwent G-POEM for refractory gastroparesis in a tertiary center with preoperative GES data. Intragastric meal distribution was measured using the proximal to distal count ratio (PDCR) at 0, 1, 2 and 4 hours, and the retention index was calculated. Clinical success was defined as a decrease of at least 50% in the Gastroparesis Cardinal Symptom Index total score after G-POEM. RESULTS: In total, 77 patients were included with a mean follow-up of 40.14 months. Clinical success was observed in 54.55% of patients. The retention index was not associated with clinical success. Only PDCR at 0 hours (PDCR0) was associated with clinical success. In univariate analysis, the median PDCR0 was 6.0 (interquartile range, 5.59) in patients with clinical success and 4.29 (interquartile range, 4.51) in patients with clinical failure (P = .019). In multivariate analysis, PDCR0 >5.25 was associated with clinical success (odds ratio, 4.36; 95% confidence interval, 1.55-12.26; P = .00524). CONCLUSIONS: This study suggests that in patients with gastroparesis, a high PDCR0 value (suggestive for a preferential fundic meal distribution) during preoperative GES is associated with long-term clinical response to G-POEM.
RESUMO
INTRODUCTION: Gastric peroral endoscopic myotomy (G-POEM) is a promising technique for treating refractory gastroparesis. We present the first double-blind randomized study comparing the clinical efficacy of G-POEM versus pyloric botulinum toxin injection (BTI). METHODS: This randomized study, conducted in two expert centers, enrolled patients with refractory gastroparesis, medically managed for >6 months and confirmed by gastric emptying scintigraphy (GES), into two groups, G-POEM versus BTI, with follow-up of 1 year. The primary end point was the 3-month clinical efficacy, defined as a >1-point decrease in the mean Gastroparesis Cardinal Symptom Index (GCSI) score. Secondary end points were: 1-year efficacy, GES evolution, adverse events, and quality of life. RESULTS: 40 patients (22 women; mean age 48.1 [SD 17.4]), with mean symptom duration of 5.8 (SD 5.7) years, were randomized. Etiologies included idiopathic (n=18), diabetes (n=11), postoperative (n=6), and mixed (n=4). G-POEM showed a higher 3-month clinical success than BTI (65% vs. 40%, respectively; P=0.10), along with non-significantly higher 1-year clinical success (60% vs. 40%, respectively) on intention-to-treat analysis. The GCSI decreased in both groups at 3 months and 1 year. Only three minor adverse events occurred in the G-POEM group. The GES improvement rate was 72% in the G-POEM group versus 50% in the BTI group (non-significant). CONCLUSION: G-POEM seems to have a higher clinically relevant success rate than BTI, but this was not statistically demonstrated. This study confirms the interest in treatments targeting the pylorus, either mechanically or chemically, for managing refractory gastroparesis.

BACKGROUND/AIMS: The evaluation of visceral hypersensitivity and gastric accommodation in patients with gastroparesis (GP) is difficult. CT-scan gastric volumetry allows to test the distension of different regions of the stomach. We aimed to study gastric volumes and patient's sensitivity to gastric distension between in patients with GP compared to patients with GERD. METHOD: Retrospective study including patients who had CT-scan volumetry for GP or GERD. Two CT-scan series were made after gastric distension: left lateral decubitus 30° (LLD30) for antrum and right lateral decubitus (RLD) for body. Pain and discomfort were assessed using visual analogue scale (VAS). Gastric volumes were measured for LLD30 and RLD. RESULTS: 13 patients (7 GP and 6 GERD) were included. Mean age was 35.6+/-7.3 years. Median gastric volume in the RLD was lower in GP vs GERD (927+/-208 ml vs. 1115+/-163 ml; p = 0.046) while it was similar for LLD30 (1053+/-228 ml vs. 1054+/-193 ml; p = 0.603). GP patients had significantly more pain and discomfort during the procedure: pain VAS for GP was 6[0-9] versus 0[0-2] for GERD, p = 0.004, discomfort VAS for GP was 7[4-10] versus 4[0-5] for GERD, p = 0.007. 66.7% of GERD patients felt no pain vs. 14.3% in GP, p = 0.053. CONCLUSION: This pilot study suggests that GP could be associated with a reduced gastric volume compared to GERD in RLD after gaseous distension. In contrast, patient self-assessment of pain related to gastric distension was greater int GP patients. A lack of fundus accommodation and visceral hypersensitivity could explain some mechanisms in the genesis of GP symptoms.
Gastroparesis is associated with lower volumes in right lateral decubitus suggesting a lower distensibility of the fundus.Gastric volumetry is more painful in patients with gastroparesis than GERD controls, suggesting visceral hypersensitivity to mechanical distension.

INTRODUCTION: The prevalence of esophageal motor disorders (EMD) in PPI-refractory gastroesophageal reflux disease (GERD) is substantial. However, limited data exist on their impact on the efficacy of endoscopic treatments like anti-reflux mucosectomy (ARMS). This study aimed to evaluate the influence of EMD on ARMS efficacy in patients with PPI-refractory GERD. METHOD: This single-center retrospective study enrolled patients with refractory GERD treated with ARMS-b (anti-reflux mucosectomy band-ligation). High-resolution esophageal manometry (HREM) was conducted before the procedure to identify EMD presence. The primary endpoint was treatment efficacy, defined as >50% improvement in GERD-HRQL score at 1 year. Secondary endpoints included PPI intake, symptom control, ARMS complications, and overall patient satisfaction at 12 months. RESULTS: The study included 65 patients, with 41 (63.1%) showing EMD on HREM. Treatment efficacy was achieved by 33.8% (22) of patients, with 8 without EMD, 11 having isolated LES hypotonia, and 3 with both LES hypotonia and esophageal body motor disorder. No significant differences were observed between patients with and without EMD regarding the primary endpoint, PPI use, symptom control, or complications. Dysphagia developed in 52.3% (34) within 6 months, leading to esophageal dilatation in 15.3% (10). Two patients experienced acute hemorrhage, and one had perforation. CONCLUSION: The presence of esophageal motor disorders does not seem to impact ARMS response, suggesting the technique's consideration in this population. Larger studies are essential for confirming these results and exploring treatment response and post-operative predictors.

BACKGROUND AND AIMS: The use of laparoscopic fundoplication (LF) to treat refractory GERD may induce refractory dysphagia (5%-10%). The management is complex, and peroral endoscopic myotomy (POEM) including valve incision is a new therapeutic option. METHODS: This retrospective study involved patients with postfundoplication refractory dysphagia treated by POEM associated with complete wrap incision. Patients were evaluated with Eckardt and dysphagia scores. Study objectives were to evaluate clinical and technical outcomes, adverse events, and GERD recurrence. RESULTS: Twenty-six patients, with a mean age of 57.3 ± 15.6 years, were included. Mean follow-up was 25.3 ± 17.6 months. The technical and clinical success rates were 96% and 84.6%, respectively. Among failures, 1 patient underwent Lewis-Santy, 2 required dilations, and 1 was lost to follow-up. Three late recurrences occurred and were endoscopically managed. Five patients (19%) had GERD recurrence that was mainly improved by proton pump inhibitors. CONCLUSIONS: POEM with fundoplication is a serious therapeutic option for managing persistent dysphagia after LF, with a low risk of GERD recurrence.
RESUMO
BACKGROUND: Peroral endoscopic myotomy (POEM) is a very effective treatment for achalasia. However, training remains non-standardized. We evaluated a training curriculum, including ex vivo cases, followed by patients' cases under expert supervision. The objective was to establish a learning curve of POEM. MATERIALS AND METHODS: Four operators having completed advanced endoscopy fellowship were involved. They had already observed > 30 cases performed by experts. They performed 30 POEMs standardized (tunnel and myotomy lengths) procedures on ex vivo porcine model. Procedural times, number/volume of injections, mucosal and serous perforations, and myotomy length were collected. The learning curve was assessed using dissection speed (DS) and a dedicated performance score (PS), including learning rate (LR) and learning plateau (LP). RESULTS: The operators completed all cases within 4 months (median of 3.5 cases/week). The mean procedural time was 43.3 min ± 14.4. Mean myotomy length was 70.0 mm ± 15.6 mm. Dissection speed averaged 1.78 mm/min ± 0.78. Using DS and PS as parameter, the LR was reached after 12.2 cases (DS = 2.0 mm/min) and 10.4 cases, respectively. When comparing the LP and the plateau phase, the DS was slower (1.3 ± 0.5 mm/min versus 2.1 ± 0.54 mm/min, p < 0.005) and perforations were decreased: 0.35 ± 0.82 in LP vs. 0.16 ± 0.44 in PP. Following this training, all operators performed 10 supervised cases and are competent in POEM. CONCLUSION: The association of observed cases and supervised ex vivo model training is effective for starting POEM on patients. The learning curve is 12 cases to reach a plateau.

BACKGROUND AND AIMS: Limited data exist concerning the long-term efficiency of gastric peroral endoscopic myotomy (G-POEM) as a treatment of refractory gastroparesis. This study evaluated the 3-year results of G-POEM in patients with refractory gastroparesis. METHODS: This was a prospective multicenter study of all G-POEM operations performed in 2 expert French centers for 46 patients with refractory gastroparesis with at least 3 years of follow-up. RESULTS: Clinical success was 65.2% at 36 months. There was significant improvement in symptom severity. Median Gastroparesis Cardinal Symptom Index decreased from 3.33 to 1.80 (P < .0001), with improvement in all subscales. We created a predictive score concerning G-POEM success (G-POEM predictive score) to which points were assigned as follows: nausea subscale <2: predictive of success, 1 point; satiety subscale >4: predictive of success, 1 point; bloating subscale >3.5: predictive of success, 1 point; percentage of gastric retention at 4 hours on scintigraphy >50%: 1 point. A threshold of 2 was identified by receiver operating characteristic curve analysis with an area under the curve of .825 that predicted clinical success with a sensitivity of 93.3% (95% confidence interval [CI], .77-.99), specificity of 56.3% (95% CI, .33-.77), positive predictive value of 80% (95% CI, .67-.93), negative predictive value of 81.8% (95% CI, .59-1.00), and accuracy of 80.4% (95% CI, .69-.92). Patients with a score ≥2 were significantly more likely to be responders at 3 years than were patients with a score <2 (80% and 18%, respectively; P = .0004). CONCLUSIONS: The clinical success of G-POEM for refractory gastroparesis was 65.2% at 36 months. Our predictive score offers an easy tool that needs to be confirmed in other studies.

INTRODUCTION: In patients with benign and refractory esophageal strictures (BES), repeating initial dilations in short intervals could be recommended, but little data are available to validate this strategy. Our aim was to evaluate long-term results of a scheduled program of repeated and sustained esophageal dilations in patients with refractory strictures. METHODS: Patients with BES requiring five or more dilations were retrospectively included and divided in two groups for analysis: a SCHEDULED group (SDG) where patients were systematically rescheduled for the 5 first dilations; ON-DEMAND group (ODG) where patients were dilated only in case of recurrence of the dysphagia. Comparison between SDG and ODG was done with a 1:1 matching analysis and etiology of stricture. Clinical success was defined as the absence of dysphagia for more than a year. RESULTS: 39 patients with refractory BES were included with post-operative stenosis in 51.2% and post-caustic injury 28.2%; 10 were in SDG and 29 in ODG. In overall analysis (39 patients), the follow-up was 64.4 ± 32 months, success rate was 79.5% and duration of treatment was 27.3 ± 20 months, and mean number of dilations was 11.7 per patient. The need for dilations decreased significantly after 18 months of treatment with an average of 0.56 dilations per semester. Self-expandable metallic stent insertion was associated with an increased rate of complications (5.9% vs 59.1% p = 0.001). In matched analysis (10 ODG vs 10 SDG patients), the duration of treatment was lower in SDG (18.8 vs 41.4 months, p = 0,032) with a higher probability of remission (survival analysis, Log-rank: p = 0,019) and the success rate did not differ between ODG and SDG patients (80% vs 90%; NS). CONCLUSION: Overall, long-term esophageal dilations resulted in a 79.5% success rate and the need for further dilatations decreased significantly in both groups after 18-month follow-up. A scheduled dilation program was associated with a higher probability of final success and lower treatment duration.

BACKGROUND: After lung transplantation (LT), gastroparesis is frequent, occurring in 25-63% of cases and leading to pulmonary infections. In refractory disease, classical management has demonstrated limited efficacy. Gastric peroral endoscopic myotomy (G-POEM) is a recently developed safe and effective procedure that has been performed here on five patients with severe post-LT gastroparesis. METHODS: In all patients, the diagnosis was confirmed by disturbed gastric emptying scintigraphy and GCSI calculation showing severe disease. Upper gastrointestinal endoscopies confirmed the absence of organic lesions. All patients were informed about the procedure and signed informed consent forms. The procedure consisted of performing an endoscopic pyloromyotomy under general anesthesia. RESULTS: The patients were between 35 and 64 years of age. Four had chronic disease, starting approximately 1 year following LT, and one had acute, severe gastroparesis requiring intubation in the intensive care unit. All patients underwent G-POEM after failure of medical treatment, without any complications. Three of the patients with chronic disease improved; they resumed a normal diet and gained weight. The patient with acute disease was discharged within a few days following the procedure and resumed oral intake. CONCLUSION: G-POEM is promising for managing post-LT refractory gastroparesis and should be further evaluated.

INTRODUCTION: Although oesophageal motor disorders (OMDs) are frequent in systemic sclerosis (SSc), the frequency of associated endoscopic lesions is unknown. We aimed at assessing the presence of endoscopic lesions in SSc patients with OMD. The secondary objective was to identify the clinical and serological profile of such patients. METHODS: This retrospective study included SSc patients suffering from OMD diagnosed by oesophageal high-resolution manometry (OHRM) and with recent upper gastro-intestinal endoscopy (UGIE). Clinical data collected were age, gender, body mass index, SSc disease duration, tobacco, SSc cutaneous type, non-digestive SSc visceral disorders, oesophageal symptoms, serological profile (autoantibodies), proton pump inhibitor use, time between SSc diagnosis and UGIE. RESULTS: 53 selected patients from 210 SSc patients investigated by OHRM in our department were included. Among these patients, 25 (47.2%) had endoscopic lesions: 18 (34.6%) had oesophagitis and 7 (13.5%) had Barrett's oesophagus. The only two parameters significantly associated with endoscopic lesions were a shorter disease duration (6 vs. 11 years; p = .002) and a shorter delay between SSc diagnosis and UGIE (3 vs. 8.5 years; p = .002). No other clinical or biological parameters could help identify the patients at risk of endoscopic lesion. CONCLUSION: In our study, only a shorter disease duration and a shorter delay between SSc diagnosis and UGIE were significantly associated with the presence of endoscopic lesions in patients with OMD, but no other parameters were identified. This study highlights the need to perform UGIE in SSc patients with OMD whatever their clinical symptoms.

INTRODUCTION: Laparoscopic fundoplication is the treatment of severe and refractory gastroesophageal reflux disease (GERD). It induces dysphagia in 5â%â-â10â% owing to a tight valve ± esophageal motility disorders (EMD), with challenging management. We assessed the first case series assessing peroral endoscopic myotomy (POEM) in such a situation. METHODS: A retrospective case series including eight patients with severe dysphagia after laparoscopic fundoplication who were treated by POEM. They were assessed clinically by Eckardt and Mellowâ-âPinkas dysphagia scores, and by high resolution manometry (HRM). The procedure was a regular esophageal POEM, mainly posterior, including a myotomy of the wrap.âThe objectives were to evaluate the clinical efficacy, technical difficulties, and complications of this approach. RESULTS: HRM showed aperistalsis in 6â/8 patients and raised lower esophageal sphincter (LES) pressure in 5â/8.âThe median preoperative Eckardt and dysphagia scores were 5 and 3.5, respectively. The procedure was completed in 7â/8 patients, with a clinical efficacy rate (normalization of both scores) of 75â% (6â/8). Although the submucosa seemed more fibrotic and vascularized, no severe complications occurred. CONCLUSION: POEM is a newly described therapeutic option to consider for managing dysphagia due to EMD after laparoscopic fundoplication.

Background: Per-oral esophageal myotomy endoscopic (E-POEM) has clearly proved safety and efficiency in the treatment of esophageal spastic disorders. Recent studies on endoscopic pyloromyotomy (G-POEM) suggest good efficiency and safety in the treatment of gastroparesis. In recent literature, some reports showed both esophageal motility disorders and gastroparesis.Methods: We report the case of four patients with esophageal and gastric motility disorders who were successfully treated with DUAL POEM (E-POEM and G-POEM) in two separate procedures.Results: Clinical improvement was reported in all patients with a decrease of the Eckardt score for esophageal motility disorders and a decrease of the GCSI score for gastroparesis. No adverse events occurred after any procedure. These reported cases suggest that is possible to perform an E-POEM and a G-POEM in the same patient in two distinct procedures.Conclusions: DUAL POEM seems to be faisable in patient with esophageal motility disorders associated with gastroparesis. The possibility of the concomitant occurrence of esophageal and gastric motility disorders could lead to change in practices with an overall assessment including gastric empting scintigraphy, high resolution manometry and pH-impedancemetry for patients with digestive motility disorders.

BACKGROUND: Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by fibrosis involving skin and multiple internal organs. Gastrointestinal manifestations occur with a prevalence of 75-90%, and severely impact the quality of life. Among them, gastric involvement may concern 50-80% of patients with gastroparesis. GPOEM has been recently proposed as effective treatment in refractory gastroparesis, reaching 80% of short-term efficacy with very low complication rate. This procedure has never been assessed in SSc patients; thus, we describe two cases of patient who benefited from GPOEM.Patients: There were 40 and 35 years old women suffering from SSc for 10 years, whom developed gastroparesis symptoms over the last year, with GCSI score of 3.4. The diagnosis was confirmed by gastric emptying scintigraphy showing increased half emptying time and residual percentages. After failure of medical therapy associating prokinetic agents and dietary measures, they were referred after multidisciplinary discussion for GPOEM procedure. The follow-up included GCSI score calculation, adverse events, and GES at 2 months. RESULTS: The procedures were uneventful, and the patients were discharged after 4 days and gradual refeeding. The post-operative GCSI 1 and 2.1, respectively, with both patients feeling significant clinical improvement, after a follow-up of 6 months. GES were also normalized in one patient. Despite improvement, one patient did not gain weight and had an additional jejunostomy. CONCLUSIONS: GPOEM may be an interesting therapeutic option in patient with SSc and severe gastroparesis after failure of classical treatment. This procedure could be proposed to patients after multidisciplinary discussion.

INTRODUCTION: Per-oral endoscopic myotomy (POEM) is effective in achalasia. The objective of this study was to evaluate the short-term clinical efficacy of POEM in non-achalasia esophageal motility disorders (NAEMD). PATIENTS AND METHODS: Patients with NAEMD diagnosed by high-resolution manometry were included in a retrospective multicentric study. For each individual case, two controls paired on gender and age were matched: one with type I/II achalasia and one with type III achalasia. The clinical response, defined by an Eckardt score ≤ 3, was assessed at 3 and 6 months. RESULTS: Ninety patients (mean age 66 years, 57 men) were included, 30 patients with NAEMD (13 jackhammer esophagus, 6 spastic esophageal disorders, 4 nutcracker esophagus, and 7 esophagogastric junction obstruction), 30 patients with type I-II achalasia, and 30 patients with type III achalasia. The 3-month response rates were 80% (24/30), 90% (27/30), and 100% (30/30) in NAEMD, type I-II achalasia and type III achalasia, respectively (p < 0.01). Eckardt scores improved from preoperative baseline in all groups (median scores 2.0 after POEM vs. 6.5 before POEM, 1.3 vs. 7.2, and 0.5 vs. 6.1 in NAEMD, type I//I and Type III, respectively). No predictive factor of response was identified. In NAEMD patients, there was a significant improvement of dysphagia, regurgitation, and chest pain scores. The 6-month response rates were 63.2% (12/19), 95.5% (21/22), and 87.0% (20/23) in NAEMD, type I-II achalasia and type III achalasia, respectively (p = 0.03). CONCLUSION: Although less effective than in achalasia, POEM is an effective treatment for NAEMD. Long-term follow-up data are needed to further confirm that POEM may be a valid treatment of NAEMD.

PURPOSE: Biofeedback therapy (BT) is a simple and effective technique for managing outlet constipation and fecal incontinence. Several clinical factors are known to predict BT response, but a 50% failure rate persists. Better selection of BT responsive patients is required. We aimed to determine whether the defecation disorder type per high-resolution manometry (HRM) was predictive of BT response. METHODS: We analyzed clinical, manometric, and ultrasound endoscopic data from patients who underwent BT in our department between January 2015 and January 2016. Patients were classified into four groups per the following defecation disorder classification criteria: rectal pressure > 40 mmHg and anal paradoxical contraction (type I); rectal pressure < 40 mmHg and anal paradoxical contraction (type II); rectal pressure > 40 mmHg and incomplete anal relaxation (type III); and rectal pressure < 40 mmHg and incomplete anal relaxation (type IV). An experienced single operator conducted ten weekly 20-min sessions. Efficacy was evaluated with the visual analog scale. RESULTS: Of 92 patients, 47 (50.5%) responded to BT. Type IV and type II defecation disorders were predictive of success (p = 0.03) (OR = 5.03 [1.02; 24.92]) and failure (p = 0.05) (OR = 0.41 [0.17; 0.99]), respectively. The KESS score severity before BT (p = 0.03) (OR = 0.9 [0.81; 0.99]) was also predictive of failure. CONCLUSION: The manometry types identified according to the defecation disorder classification criteria were predictive of BT response. Our data confirm the role of three-dimensional HRM in the therapeutic management of anorectal functional disorders.

BACKGROUND: The aim of the study was to describe the results of 3D high-resolution anorectal manometry (3DHRAM) in a large cohort of patients with functional anorectal disorders. METHODS: In this single-center retrospective study, all consecutive patients referred for investigation of fecal incontinence (FI) or dyssynergic defecation (DD) underwent 3DHRAM. The parameters analyzed were usual manometric data, repartition of dyssynergic patterns, and the prevalence of a new "muscular subtype classification" underlying dyssynergia, anal sphincter defects, and pelvic floor disorders. RESULTS: Final analyses were performed in 1477 patients with a mean age 54 ± 16 years; 825 patients suffered from DD, and 652 patients suffered from FI. Among these patients, 86% met the diagnostic criteria for dyssynergia. Type II dyssynergia was the most frequently observed (56%) in women and men suffering from FI and in women with DD. Type I was the most frequently observed in men with DD (49%). Regarding the muscle type subgroups, combined puborectalis muscle involvement with an external anal sphincter profile was the most frequently observed. The global prevalence of rectal intussusception and excessive perineal descent were 12% and 21%, respectively. Type III dyssynergia was more frequently associated with pelvic floor disorders than were other types of dyssynergia (p < 0.001). CONCLUSION: This large cohort study provides reference values for 3DHRAM in patients with functional anorectal disorders. Further studies are necessary to assess the prevalence of pelvic floor disorders in healthy volunteers and to develop new scores and classifications including all of these new parameters.

OBJECTIVES: High-resolution manometry (HRM) is the gold standard for diagnosis of esophageal motility disorders. However, clinical signs associated with these disorders are nonspecific, and it is difficult to correlate clinical signs with HRM data. The main objective of our study was to assess the positive predictive value (PPV) and negative predictive value (NPV) of each clinical sign, as well as their sensitivity and specificity in the diagnosis of esophageal motility disorders. METHODS: This is a bicentric retrospective cohort study based on HRM data collected between May 2012 and May 2016. The studied symptoms were weight loss, feeding difficulties, swallowing disorders, dysphagia, food blockages, vomiting, gastroesophageal reflux disease (GERD), belching, and respiratory symptoms. HRM data were analyzed according to the Chicago Classification (3.0). RESULTS: In total, 271 HRM data were analyzed, of which 90.4% showed abnormal results. HRM was well tolerated in 91% of the cases. The most common esophageal motility disorder was ineffective esophageal motility (38%). Weight loss was significantly associated (Pâ=â0.003) with an abnormal HRM with a 96% PPV. CONCLUSIONS: With nonspecific clinical signs suggesting an esophageal motility disorder, weight loss was a predictive sign of abnormal HRM results. HRM was well tolerated in pediatric patients, and ineffective esophageal motility appears to be the most frequent motility disorder in our cohort, as already observed in adult patient studies.

INTRODUCTION AND HYPOTHESIS: Wearing high heels may not only produce deleterious effects on the musculoskeletal system and on the general posture, but also on the activity of pelvic floor muscles. However, no data are currently available concerning the link between fecal incontinence and wearing high heels. Our aim was to determine whether wearing high-heeled shoes could influence anal canal pressure values in patients suffering from fecal incontinence. METHODS: In this retrospective monocentric study, 338 female patients were included. Clinical data, including the Wexner score, and manometric data were recorded (using 3D high-resolution anorectal manometry). Wearing high heels was defined by the use of high-heeled shoes at least four times a week for 4 consecutive hours with at least 1 year of usage time and heels ≥3 cm. Two sub-groups were defined: "high heels" vs "no high heels." RESULTS: The two subgroups were comparable for clinical data, including Wexner score, except for a higher age, menopause and hormone replacement therapy, and urinary incontinence in the group with "high heels." No statistical difference was observed concerning the anal canal pressure. Using analysis by logistic regression, only age was related to a significantly lower resting pressure. CONCLUSIONS: In this retrospective cohort of women with fecal incontinence, no clinical or manometric differences were observed between women who wore high heels versus those who did not. Because there is limited knowledge on this potential link and because the pelvic tilt may vary according to age and the habit of walking with high heels, further studies are necessary.

BACKGROUND: Most studies on the human microbiota have analyzed stool samples, although a large proportion of the absorption of nutrients takes place in upper gut tract. We collected samples from different locations along the entire gastrointestinal tract from six patients who had simultaneously undergone upper endoscopy and colonoscopy, to perform a comprehensive analysis using culturomics with matrix assisted laser desorption ionisation - time of flight (MALDI-TOF) identification and by metagenomics targeting the 16S ribosomal ribonucleic acid (rRNA) gene. RESULTS: Using culturomics, we isolated 368 different bacterial species, including 37 new species. Fewer species were isolated in the upper gut: 110 in the stomach and 106 in the duodenum, while 235 were isolated from the left colon (p < 0.02). We isolated fewer aero-intolerant species in the upper gut: 37 from the stomach and 150 from the left colon (p < 0.004). Using metagenomics, 1,021 species were identified. The upper gut microbiota was revealed to be less rich than the lower gut microbiota, with 37,622 reads from the stomach, 28,390 from the duodenum, and 79,047 from the left colon (p < 0.009). There were fewer reads for aero-intolerant species in the upper gut (8,656 in the stomach, 5,188 in the duodenum and 72,262 in the left colon, p < 0.02). Patients taking proton pump inhibitors (PPI) were then revealed to have a higher stomach pH and a greater diversity of species in the upper digestive tract than patients not receiving treatment (p < 0.001). CONCLUSION: Significant modifications in bacterial composition and diversity exist throughout the gastrointestinal tract. We suggest that the upper gut may be key to understanding the relationship between the gut microbiota and health.
