Does the presence of an esophageal motor disorder influence the response to anti-reflux mucosectomy (ARMS) for refractory GERD?

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.

Mid-gastric peroral endoscopic myotomy in the treatment of post-sleeve gastrectomy gastric tube twist: Four cases.

Background and study aims Laparoscopic sleeve gastrectomy (LSG) may lead to symptomatic mid-gastric twist in 0.1% to 4% of cases. Endoscopic balloon dilatation often fails, requiring a switch to Roux-en-Y bypass. Submucosal endoscopic treatment is expanding, so we propose a new technique of fibrosis incision after tunnelization, called medio-gastric peroral endoscopic myotomy (MG-POEM). Patients and methods Four patients aged 41 to 70 years underwent MG-POEM in 2020 for symptomatic post-LSG medio-gastric twist. The aim was to describe the technique, and document the efficacy, using the Gastric Outlet Obstruction Scoring System (GOOSS) score and a quality-of-life scale (QOLS). The procedures consisted of a POEM with myotomy and fibrosis incision. Results Median preoperative GOOSS and QOLS were 1/3 ([0-3] and 1.75/10 [0-10], respectively. All procedures were technically successful. One patient had immediate postoperative complications, which were treated conservatively. The median follow-up was 18 months. All patients had improved quality of life and food intake, with median postoperative GOOSS and QOLS of 3/3 and 6,5/10 [6-8], respectively. Two patients required additional pneumatic dilatation for scarring strictures. Follow-up endoscopies and esophagograms showed that the twist had disappeared. Conclusions MG-POEM shows promise for safe and effective management of post-LSG mid-gastric twist, despite requiring a high level of endoscopic skill to perform submucosal tunneling.

Gastric volumetry for the assessment of fundic compliance and visceral hypersensitivity in patients with gastroparesis: a retrospective comparative study.

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.

Gastric peroral endoscopic myotomy versus botulinum toxin injection for the treatment of refractory gastroparesis: results of a double-blind randomized controlled study.

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.

Intrarectal injections of botulinum toxin versus placebo for the treatment of urge faecal incontinence in adults (FI-Toxin): a double-blind, multicentre, randomised, controlled phase 3 study.

BACKGROUND: Non-randomised studies assessing intrarectal botulinum toxin type A (BoNTA) injections for faecal incontinence are promising. We aimed to evaluate the efficacy of BoNTA for the treatment of faecal incontinence in a randomised study. METHODS: In this randomised, double-blind, placebo-controlled study, we included adult patients who had at least one urgency or faecal incontinence episode per week for at least 3 months and who had experienced a failure of conservative or surgical treatment from eight French specialist hospital units with the skills to manage patients with faecal incontinence. Patients were randomly assigned (1:1) by a central web form to receive intrarectal submucosal injections of either 200 units of BoNTA (Botox; Allergan, Irvine, CA, USA; BoNTA group) or an equivalent volume of saline (placebo group), stratified by Cleveland Clinic Severity scores (CCS score; ≥12 or <12). Patients, investigators, study site staff, and sponsor personnel were masked to treatment allocation up to the 6-month visit. The primary endpoint was the number of episodes of faecal incontinence and urgency per day assessed using 21-day patient bowel diaries 3 months after the treatment. The primary analysis was performed using a modified intention-to-treat (mITT) approach (ie, in all the randomised patients who had received a treatment) with adjustment for baseline faecal incontinence and urgency episodes. After the final data collection at 6 months after injections, patients were unmasked and offered the BoNTA treatment if they were in the placebo group (rescue therapy) without masking, with an additional 6 months of safety follow-up. This trial is registered with ClinicalTrials.gov, number NCT02414425. FINDINGS: Between Nov 25, 2015, and Nov 25, 2020, we randomly assigned 200 patients to receive either BoNTA (n=100) or placebo (n=100) injections. Due to withdrawals before the injections, 96 patients were included in the BoNTA group and 95 patients were included in the placebo group (mITT analysis). The mean number of faecal incontinence and urgency episodes per day in the BoNTA group decreased from 1·9 (SD 2·2) at baseline to 0·8 (1·8) at 3 months after the injections, and from 1·4 (1·1) to 1·0 (1·0) in the placebo group, with a baseline-adjusted mean group difference at 3 months estimated at -0·51 (95% CI -0·80 to -0·21, p=0·0008). No serious treatment-related adverse events were reported in the trial. The most frequently reported non-serious adverse event (treatment related or not) following the BoNTA or placebo injections was constipation (reported in 68 [40%] of 169 patients who received the BoNTA injections and 38 [40%] of 95 patients who received placebo injections). INTERPRETATION: BoNTA injections are an efficacious treatment for urge faecal incontinence. Further research will define the optimum selection criteria, dose, site of injection, re-injection frequency, and long-term results.

Peroral endoscopic myotomy and valve section for treatment of persistent and disabling dysphagia after laparoscopic fundoplication (with video).

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.

Interferential therapy for chronic constipation in adults: The CON-COUR randomizedcontrolled trial.

BACKGROUND: Chronic constipation (CC) is a frequent condition, and the first-line treatment includes dietary rules, the use of laxatives, and biofeedback for evacuation disorders. However, almost half of the patients are dissatisfied with their current treatment. We report the first double-blind randomized multicenter trial assessing the effectiveness of transabdominal electrical stimulation by interferential therapy (IFT) in the treatment of CC in adults. METHODS: A prospective, multicenter, randomized, double-blind, sham-controlled, parallel-group, phase 3 trial was conducted at 7 centers in France. The primary endpoint was 8-week efficacy as defined by the number of complete spontaneous bowel movements during the last 4 weeks of the 8-week stimulation period. Secondary endpoints included the evaluation of the effects of IFT on symptoms (Patient Assessment of Constipation Symptoms questionnair (PAC-SYM)), quality of life (QOL) (Patient Assessment of Constipation Quality of Life), Colonic transit time (CTT), anorectal manometry, and patient satisfaction. RESULTS: The proportion of 8-week responders was not significantly different between the two groups (73.2% in the IFT group vs. 67.1% in the sham group). After 8 weeks of stimulation, the mean overall PAC-SYM score and the mean reduction in the overall PAC-SYM score were significantly greater in the IFT group than in the sham group. No differences were observed concerning CTT, anorectal manometry, or patient satisfaction. CONCLUSIONS: Although the primary endpoint was not reached, IFT can significantly alleviate the symptoms and improve the QOL of CC patients. It can be assumed that new treatments require different modes of evaluation and that the assessment of patient-reported outcomes may become a priority among therapeutic targets of CC. Trial registration number NCT02381665.

Gastric electrical stimulation versus per-oral pyloromyotomy for the treatment of nausea and vomiting associated with gastroparesis: An observational study of two cohorts.

BACKGROUND: Both gastric electrical stimulation (GES) and gastric-peroral endoscopic myotomy (G-POEM) can be offered to patients with gastroparesis and predominant nausea and vomiting. The study's aim was to compare GES and G-POEM efficacy on nausea and vomiting scores in patients with gastroparesis. METHODS: Two multicenter cohorts of patients with medically refractory gastroparesis with predominant nausea and vomiting (defined as a score >2 on nausea and vomiting subscale that varied from 0 to 4) were treated either with GES (n = 34) or G-POEM (n = 30) and were followed for 24 months (M). Clinical response was defined as a decrease of ≥1 point in nausea and vomiting subscale without premature exclusion due to switch from one to the other technique before M24. Changes in symptomatic scales and quality of life were also monitored. KEY RESULTS: Patients from both groups were comparable although the mean score of nausea and vomiting subscale was higher in GES (3.0) compared to G-POEM group (2.6; p = 0.01). At M24, clinical response was achieved in 21/34 (61.7%) patients with GES and in 21/30 (70.0%; p = 0.60) patients with G-POEM. Mean scores of nausea and vomiting subscale decreased at M24 in both GES (from 3.0 to 1.6; p < 0.001) and G-POEM (from 2.6 to 1.2; p < 0.001) groups, although there was no difference between groups (difference adjusted from baseline: -0.28 [-0.77; 0.19]; p = 0.24). Likewise, symptomatic and quality of life scores improved at M24 in both groups, without difference according to treatment group. CONCLUSIONS AND INFERENCES: At M24, we did not observe significant difference in efficacy of GES and G-POEM in medically refractory gastroparesis with predominant nausea and vomiting.

Training in esophageal peroral endoscopic myotomy (POEM) on an ex vivo porcine model: learning curve study and training strategy.

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.

Does fecal calprotectin increase may be linked to lactose intolerance in patients with irritable bowel syndrome?

BACKGROUND: Irritable bowel syndrome (IBS) is a multifactorial condition without any specific investigation. Fecal calprotectin (FC) may be elevated in IBS without any explanation. In addition, some patients with IBS have symptoms related to lactose intolerance. Our main aim was to investigate whether an increase in FC could be related to lactose intolerance in patients with IBS. METHODS: In this retrospective single-center study, all patients with IBS who have underwent a FC test and a lactose respiratory test within a period of less than 6 months were eligible. A FC greater than or equal to 50 µg/g was considered abnormal. RESULTS: Severnty-six patients (48 females), mean age 38±15 years were included. Symptoms were respectively: bloating in 57%, diarrhea in 76% and abdominal pain in 46% of cases. Among the 76 patients: 22 (29%) had FC≥50 µg/g and 9/22 (41%) had a positive lactose test. No significant relationship could be identified between the increase in FC and the lactose test positivity. The value of the FC was also not related to the subtype of IBS or the positivity of the glucose test. CONCLUSIONS: In our study, the increase in FC was not significantly related to the presence of lactose intolerance. Nevertheless, our work, despite its originality, is limited by its retrospective nature and small number of patients. Future studies including larger numbers of patients may identify the causes of elevated FC in patients with IBS to individualize different subgroups of patients to best adapt therapeutic management.

Evaluation of the safety profile of endoscopic pyloromyotomy by G-POEM: a French multicenter study.

Background: Gastric per oral endoscopic esophageal myotomy (G-POEM) is a promising procedure to treat refractory gastroparesis. The safety profile of G-POEM is an important topic because gastroparesis is a functional pathology, with a procedure whose effectiveness is between 50 and 65% depending on the studies. Objectives: We present this retrospective multicenter study, with the aim of establishing a safety profile, focusing on serious adverse events (AEs). Design: This was a multicenter observational cohort study conducted in five French expert centers. Methods: All patients who underwent G-POEM for refractory gastroparesis between 2015 and 2021 were included for analysis. AEs were classified into per endoscopic, early postoperative, and late postoperative, up to 1 month. Their severity was assessed using Dindo-Clavien and American Society for Gastrointestinal Endoscopy classification. The primary objective was to evaluate the rate of G-POEM severe AEs. Secondary objectives were to document other postoperative AEs, and to identify predictive factors. Results: In all, 217 patients were included: 81 men and 136 women, mean age 52 ± 17 years. The average procedural time was 44 ± 14 min (12-78). The average hospital stay was 3.7 ± 2.3 days. The AEs rate classified as Clavien-Dindo ⩾3 was 0.4% (one delayed bleeding requiring blood transfusion and endoscopic management). There were no deaths or patients admitted to intensive care unit. The rates of mucosotomy and capnoperitoneum were 3.7 and 1.8%, respectively, without clinical consequences. Most patients (81.5%) did not experience any AE. Three cases of dumping syndrome occurred, quickly managed by dietary measures. Conclusion: Our study confirms the safety of G-POEM with less than 0.5% of serious AEs, medically managed. This outcome makes this a procedure to have a good benefit-risk ratio.

Gastric peroral endoscopic myotomy in refractory gastroparesis: long-term outcomes and predictive score to improve patient selection.

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.

Assessment of long-term results of repeated dilations and impact of a scheduled program of dilations for refractory esophageal strictures: a retrospective case-control study.

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.

Treatment of anal fissures: Results from a national survey on French practice.

BACKGROUND: Treatment of an anal fissure (AF) is based on medical treatment (nonoperative therapies) and surgical procedures. However, the choice of treatment and its role in therapeutic strategy vary from one country to another, and to date, no standard French recommendation is currently available. Our aim was to assess French practices in the treatment of AFs. METHODS: A national survey of members of the French National Society of Colo-Proctology (SNFCP) was carried out using an online questionnaire (1) to evaluate French practice and (2) to compare them with guidelines of other societies. RESULTS: Two hundred responses were obtained among the 300 registered members, representing a participation rate of 67%. Members of the SNFCP agree with all scientific societies on the importance of first-line medical treatment, with surgery proposed as a second-line treatment in the case of the failure of well-conducted medical treatment. However, calcium channel blockers and topical nitrates as first-line treatment are rarely prescribed in France. Priority is therefore given to "simple" topical healing products and oral analgesics on demand. Similarly, surgical management differs since LIS is the "gold standard" in most guidelines, whereas in France, despite the data in the literature, fissurectomy is the first-line treatment. CONCLUSIONS: Our study indicated the fissure treatment discrepancies of France with other countries concerning the usage of topical treatments and the choice of first-line surgical treatments that is currently considered a "French exception".

Dysphagia in Children, Do Not Blame Eosinophils Too Quickly.

Dysphagia in children is a relatively frequent symptom in childhood, and the main causes are congenital and linked to ear-nose-throat etiologies. However, non-congenital esophageal dysphagia is less common, and the main cause in such cases is eosinophilic esophagitis (EoE). When there is no response to a well-conducted treatment, with normalization of histology, the diagnosis of EoE must then be reconsidered. Here, we present the case of a 10-year-old patient whose initial diagnosis of eosinophilic esophagitis delayed the diagnosis of type III achalasia.

Severe acute ischemic colitis: What is the place of endoscopy in the management strategy?

Background and study aims Ischemic colitis (IC) is potentially lethal. Clinical and biology information and results of computed tomography (CT) scan and/or colonoscopy are used to assess its severity. However, decision-making about therapy remains a challenge. Patients and methods This was a retrospective, single-center study between 2006 and 2015. Patients with severe IC who underwent endoscopic evaluation were included. The aims were to determine outcomes depending on endoscopic findings and assess the role of endoscopy in the management. Results A total of 71 patients were included (men = 48 (68%), mean age = 71 ±â€Š13 years). There was hemodynamic instability in 29 patients (41 %) and severity signs on CT scan in 18 (38 %). Twenty-nine patients (41 %) underwent surgery and 24 (34 %) died. The endoscopic grades were: 15 grade 1 (21 %), 32 grade 2 (45 %), and 24 grade 3 (34%). Regarding patients with grade 3 IC, 55 % had hemodynamic instability, 58 % had severity signs on CT scan, 68 % underwent surgery, and 55 % died. The decision to perform surgery was based on hemodynamic status in 62 % of cases, CT scan data in 14 %, endoscopic findings in 10 %, and other in 14 %. Colectomy was more frequent in patients with grade 3 IC ( P  < 0.05). A mismatch between mucosal aspect (necrosis) and serous (normal) was observed in 13 patients (46 %). Risk factors for colectomy in univariate analysis were aortic aneurysm surgery, hemodynamic instability, no colic enhancement on CT scan, and endoscopic grade 3. Risk factors for mortality in multivariate analysis were hemodynamic instability, colectomy, and Charlson score > 5 ( P  < 0.05). Conclusions This study suggests a low impact of endoscopy on surgical decision making. Hemodynamic instability was the first indication for colectomy. A discrepancy between endoscopic mucosal (necrosis) and surgical serous (normal) aspects was frequently noted.
