RESUMEN
Endoscopic retrograde cholangiopancreatography [ERCP] is a complex procedure with a flat learning curve. It is associated with the risk of serious complications such as pancreatitis, bleeding, cholangitis and perforation. Endosonography should therefore also be offered for the precise indication of the higher-risk ERCP. Numerous factors influence the success of ERCP. In addition to structured training for the initial acquisition of skills and a minimum number of ERCPs of varying degrees of difficulty, maintaining a good quality of ERCP also requires a regular minimum number of examinations performed per year. There is extensive evidence that shows a significant correlation between ERCP volumes and primary success rates, lower lengths of hospital stay, fewer unwanted readmissions and fewer complications. The cut-offs for differentiating between high-volume and low-volume centers were chosen inconsistently in the studies, with the highest evidence for a cut-off value of 200 ERCPs/year. The question of specialization in ERCP has been given a relevance by the current developments in german hospital reform. Here, a minimum number of ERCPs should be defined for groups of different specialization. However, a minimum number alone will not be able to achieve good treatment quality. In terms of high-quality patient care, it is necessary to offer ERCPs in specialized gastroenterology center, which, in addition to a sufficient number of ERCPs for training and to maintain competence, offer an on-call service and complementary procedures such as EUS and which are embedded in appropriately accessible clinics that have the necessary resources for complication management.

INTRODUCTION: The treatment of gastroparesis can be difficult in everyday clinical practice. The aim of this anonymous survey of members of the Arbeitsgemeinschaft Leitender Gastroenterologischer Krankenhausärzte e.V. (ALGK) was to investigate the management of gastroparesis care in Germany. MATERIAL AND METHODS: The ALGK conducted a member survey using a standardized anonymous questionnaire including 11 questions from 14.04.2023 to 29.04.2023. The questions covered diagnostic and therapeutic procedures as well as various aspects of the management of gastroparesis. RESULTS: The response rate was 21.4% (62 members). Only 6.56% of all respondents assessed the prevalence of gastroparesis correctly as estimated by current epidemiological publications. 68.85 % of all respondents used gastric emptying scintigraphy for diagnosis. 51.61% regarded an individualized therapy as the most important treatment goal, taking into account etiology and impact of symptoms, compared to symptomatic treatment of leading clinical symptom in 43,55 %. First choice treatment was medical treatment in 41.94%, dietary recommendations in 27.42% and endoscopic interventions in 24.2%. 100% of respondents used prokinetics, 40.32% used antiemetics while only 4.84% used analgesics. Insufficient availability of medical treatment options represents a need of action for 85.48%, compared to lacking official approval of available drugs for this indication for 48,39% of all respondents. Treatment options with little evidence were used quite frequently (e.g. use of herbal therapies in 43.55%). DISCUSSION: Overall, the frequency of gastroparesis was underestimated in the current survey. Endoscopic options are quite often used as first-line treatment. Although symptom-guided treatment is important for the majority of respondents, prokinetics are predominantly used.
RESUMEN
Introduction: We previously showed enteric nerve activation after application of colonic mucosal biopsy supernatants from patients with irritable bowel syndrome (IBS). The question remains whether this is a region-specific or a generalized sensitization. We tested the nerve-activating properties of supernatants from large and small intestinal regions of IBS patients with diarrhea (IBS-D) in comparison to those from mastocytosis patients with diarrhea (MC-D) or non-IBS/non-MC patients with GI-complaints. MC-D patients were included to test samples from patients with an established, severe mast cell disorder, because mast cells are suggested to play a role in IBS. Methods: Voltage-sensitive dye imaging was used to record the effects of mucosal biopsy supernatants from IBS-D, MC-D, and non-IBS/non-MC on guinea pig submucous neurons. Mast cell density and histamine concentrations were measured in all samples. Results: The median neuroindex (spike frequency × % responding neurons in Hz × %) was significantly (all p < 0.001) increased for IBS-D (duodenum and colon, proximal and distal each, 49.3; 50.5; 63.7; 71.9, respectively) compared to non-IBS/non-MC (duodenum and colon, proximal and distal each, 8.7; 4.9; 6.9; 5.4, respectively) or MC-D supernatants (duodenum and colon, proximal and distal each, 9.4; 11.9; 0.0; 7.9, respectively). Nerve activation by MC-D and non-IBS/non-MC supernatants was comparable (p>0.05). Mast cell density or histamine concentrations were not different between IBS-D, MC-D, and non-IBS/non-MC samples. Discussion: Nerve activation by biopsy supernatants is an IBS hallmark that occurs throughout the gut, unrelated to mast cell density or histamine concentration. At least as important is our finding that GI complaints per se were not associated with biopsy supernatant-induced nerve activation, which further stresses the relevance of altered nerve behavior in IBS.
RESUMEN
BACKGROUND AND STUDY AIMS: Gastrointestinal adverse reaction to food (GARF) is reported frequently in the general population and even more in patients with disorders of the gut brain axis. However, there is a significant difference between self-reported and objective proven GARF. The aim of the study was to characterize a mucosal correlate of GARF by endoscopic confocal laser endomicroscopy (eCLE) with duodenal food challenge (DFC). PATIENTS AND METHODS: In an observational and proof of concept study we evaluated 71 patients with disorders of the gut brain axis without (group I, n=19) and with (group II, n=52) GARF by eCLE and DFC. Spontaneous and food induced transfer of fluorescein into duodenal lumen was detected 10 minutes following intravenously application of fluorescein and 10 minutes after DFC. RESULTS: According to Rom IV, the patients (group I/II) could be classified as irritable bowel syndrome (IBS) 32%/31%, functional abdominal pain without changes in bowel movement 47 %/48 %, functional abdominal bloating/distension 0 %/10 %, functional diarrhea 5 %/ 2 %, and unspecified functional bowel disorder 16 %/10 %, respectively. 21 %/27 % of the patients responded with a fluorescein leakage into the duodenal lumen before and 74 %/69 % following to DFC. Frequency rank order of food components that induced a response were soy (55.5 %/60 %), wheat (60 %/45.5 %), egg (35.7 %/8.3), milk (30 %/18.2 %) and yeast (10 %/6.6 %), respectively. Histology of duodenal biopsies, number, form and distribution of intraepithelial lymphocytes and mucosal mast cells as well as mast cell function were normal. Overall, 14 %/79 % reported main symptom benefit following a food exclusion therapy according to eCLE and DFC that was significant different between the groups. CONCLUSION: The results of our study indicate that eCLE with DFC is a technique to clinically evaluate patients with disorders of the gut brain axis and GARF resulting in a high proportion of patients reporting symptom benefit upon food exclusion dietary advice focussed on the results of eCLE.

Acute abdominal pain may relate to specific organ systems and needs an interdisciplinary approach with close collaboration between internal and surgical disciplines. Main objective is to shorten the diagnostic work-up between the beginning of the symptoms and their therapy. After clarifying of the five w-questions: when, how, how long, why, and where, abdominal ultrasound, ECG, laboratory diagnostics and early application of computed tomography should be performed.For the most part, chronic abdominal pain is caused by disorders of the gut-brain-axis such as the irritable bowel syndrome. Because of the synaptic plasticity, the processing of pain is dynamic and cannot be related to a single organ system. This problem is obvious in patients with irritable bowel syndrome and colonic diverticula, which may be interpreted as symptomatic uncomplicated diverticular disease (SUDD, type 3a). However, a reliable clinical differentiation between both groups is not possible. The establishment of SUDD (type 3a) considerable widened the application area of mesalazine.

BACKGROUND: Endoscopic confocal laser endomicroscopy (eCLE) is an established technique that allows clinical evaluation of mucosal integrity by fluorescein leaking through the mucosa upon duodenal food challenge (DFC). Analysis of eCLE with DFC in eosinophilic esophagitis (EoE) would be interesting to evaluate epithelial barrier dysfunction also in other regions of the gastrointestinal tract and to characterize potential individual food allergens that trigger the esophageal inflammation. METHODS: In an observational and proof of concept study we evaluated 9 patients with histologically proven EoE by eCLE and DFC. Severity of symptoms were graduated according to the validated symptom-based EoE activity index. The endoscopic appearance of the esophagus was described according to the Endoscopic Reference Score System (ERERS). Spontaneous and food induced transfer of fluorescein into duodenal lumen were detected 10 minutes following intravenously application of fluorescein and 10 minutes after DFC. Food allergens were yeast, egg, soy, milk, and wheat, respectively. Local application of sodium chloride solution 10 % to the duodenal mucosa before DFC served as a control. Patients responding to DFC received a dietary exclusion therapy according to the results of DFC. RESULTS: We investigated 9 patients with EoE (8 men, 49.7±13.8, 36-76 years). Symptom-based EoE activity index was 79±27.4, 33-100. In all patients EoE was confirmed by histology with number of esophageal mucosal eosinophilic granulocytes > 15/HPF, (91.4±77.4, 42-263). Mean ERERS score was 4.5±1.3, 3-7. None of the patients was aware of any food intolerance. eCLE revealed one patient with spontaneous transfer of i. v. fluorescein into duodenal lumen before DFC ("leaky gut"). 40 DFC were performed in the remaining 8 patients of whom 5 patients (61 %) responded to DFC. Rank order of fluorescein leakage upon DFC was wheat and milk in 37.5 % each, soy in 25 %, and egg in 12.5 %. The patients were treated by PPI (n=9), esophageal bouginage (n=5) and/or local corticoid therapy (n=3). The 5 patients responding to DFC received an additional food exclusion dietary advice focussed on the results of DFC. All patients reported a reduction of their symptoms. EoE activity indexes of patients with positive DFC were 73.7+28.6, 33-100 before and 22.7+37.9, 0-79 four weeks after food exclusion. CONCLUSION: The findings of our proof of concept study suggest that eCLE with DFC may be an interesting tool to further evaluate patients with EoE. This technique has the potential to identify patients who may benefit from an additional individual dietary therapy.

Gastroenterology has made crucial advances in diagnostic and interventional endoscopic procedures, opening up improvements in the treatment of many patients. Thus, organ-preserving treatments are increasingly being made possible, replacing more invasive organ resecting surgical procedures. At the same time, the degree of complexity and risks varies widely between different endoscopic procedures. In many cases, simpler endoscopic procedures are now offered on an outpatient basis. Further potential for cross-sectoral performance of endoscopic procedures exists in the case of complex endoscopic procedures, which, however, require special structural, procedural and personnel requirements in order to provide quality-assured treatment, enable post-interventional monitoring and, if necessary, take measures to ensure the success of the treatment. We summarize the essential prerequisites and limitations for cross-sector performance of endoscopic procedures in gastroenterology.

BACKGROUND: Neurogastroenterological disorders (NGDs) are highly prevalent and substantially impact patients' quality of life. Effective treatment of NGDs depends on the competence and training of medical caregivers. Students' perceived competence in neurogastroenterology and its place in medical school curricula are assessed in this study. METHODS: A multi-center digital survey among medical students was conducted at five universities. Self-ratings of competence regarding basic mechanisms, diagnosis, and treatment of six chronic medical conditions were assessed. These included irritable bowel syndrome (IBS), gastroesophageal reflux disease, and achalasia. Ulcerative colitis, hypertension, and migraine were included as references. KEY RESULTS: Of 231 participants, 38% remembered that neurogastroenterology was covered in their curriculum. Highest competence ratings were stated for hypertension and the lowest for IBS. These findings were identical for all institutions irrespective of their curricular model and demographic parameters. Students who remembered neurogastroenterology as a part of their curriculum reported higher competence ratings. According to 72% of students, NGDs should be highlighted more prominently in the curriculum. CONCLUSIONS & INFERENCES: Despite its epidemiological relevance, neurogastroenterology is only weakly represented in medical curricula. Students report low levels of subjective competence in handling NGDs. In general, assessing the learners' perspective on an empirical basis may enrichen the process of national standardization of medical school curricula.

BACKGROUND: The removal of bolus impaction within the esophagus is an indication for emergency endoscopy. The current guideline of the European Society of Gastrointestinal Endoscopy (ESGE) recommends gently pushing the bolus into the stomach. This view is discerned by many endoscopists because of the increased risk of complications. In addition, the use of an endoscopic cap for bolus removal is not mentioned. MATERIAL AND METHODS: In a retrospective analysis from 2017 to 2021 we investigated 66 adults and 11 children with acute bolus impaction within the esophagus. RESULTS: Eosinophilic esophagitis, reflux esophagitic /peptic stenosis and Schatzki Ring caused 57.6%, esophageal and bronchial carcinoma 18%, esophageal motility disorders 4.5%, Zenkers diverticulum 1.5% and radiation esophagitis 1.5% of the bolus obstructions. The reason remained unclear in 16.7% of the cases. The spectrum was comparable in children with additional 2 cases with esophageal atresia and stenosis. The reason was unclear in 2 cases. Removal of bolus impaction was successful in 92.4% in adults and 100% in children. Bolus obstruction in adults was successfully removed solely by endoscopic cap in 57.6% and 75% in children. Pushing the bolus into the stomach without disintegration was possible in only 9% of cases. CONCLUSION: Flexible endoscopy is an effective ermergency intervention for removal of bolus obstruction within the esophagus. Uncontrolled pushing the bolus into the stomach without view cannot be recommended. An endoscopic cap is a good extension for safe bolus removal.

Background and study aims Gastrointestinal symptoms assumed to be caused by food intolerance are reported frequently in the general population. There is a significant difference between self-reported and objective proven food intolerance, as shown by placebo-controlled, double-blind, randomized trials. This discrepancy may be overcome by endoscopic confocal laser endomicroscopy (eCLE). Patients and methods In an observational study we evaluated 34 patients with functional abdominal pain and adverse reaction to food by eCLE and local duodenal food challenge for the first time. Spontaneous and food-induced transfer of fluorescein into the duodenal lumen was detected 10 minutes after intravenously application of fluorescein and 10 minutes after duodenal food challenge (DFC). Results Of the patients, 67.6â% responded with a fluorescein leakage into the duodenal lumen. Frequency rank order of food antigens that induced a response were soy (50â%), wheat (46.1â%), milk (20â%), egg (12â%), and yeast (11.5â%), respectively. Of the patients, 23.5â% showed spontaneous leakage of fluorescein, suggesting leaky gut syndrome. Histology of duodenal biopsies and mast cell function were normal. Overall, 69.5â% of patients improved with food exclusion therapy and 13â% were symptom-free according to eCLE. Conclusions The results of our study indicate that eCLE is a clinically useful tool to evaluate patients with functional abdominal pain and adverse reaction to food and to create individualized dietary therapy with clinical benefit for patients.
RESUMEN
INTRODUCTION: This systematic review summarizes published data on Menthacarin, the proprietary combination of peppermint oil and caraway oil, in the treatment of functional gastrointestinal disorders. Efficacy was assessed by meta-analysis of placebo-controlled trials. METHODS: We searched PubMed, the Cochrane Library, and the manufacturer's information system for clinical studies investigating the safety and efficacy of Menthacarin. Efficacy analyses included change from baseline of epigastric pain and general improvement of the patients' condition. RESULTS: Five randomized trials involving 580 patients were found, demonstrating significant effects of Menthacarin on symptoms of functional dyspepsia (FD) compared to placebo or similar effects compared to a reference drug. Seven other studies reported favorable results on therapeutic application in FD patients with concomitant Helicobacter pylori infection, in irritable bowel syndrome (IBS), and on tolerability in FD patients from 12 years of age. Three trials in FD with 249 patients were eligible for meta-analysis. Results demonstrate a significant reduction in pain intensity (standardized mean difference: 0.80; 95% confidence interval (CI): 0.39-1.21) and in item 2 of the Clinical Global Impression Scale (risk ratio: 2.65; 95% CI: 1.81-3.87) for Menthacarin. CONCLUSIONS: Menthacarin was shown to be effective and safe for the treatment of FD and represents a promising option for symptoms of IBS.

BACKGROUND: Intestinal epithelial barrier dysfunction ("leaky gut syndrome", LGS) is thought to play a major role in the pathogenesis of disorders of the gut brain axis. Endoscopic confocal laser endomicroscopy (eCLE) is an objective measure to test duodenal permeability. We applied this technique in patients with functional gastrointestinal symptoms and food intolerance to characterize the proportion of patients with LGS. MATERIAL AND METHODS: In an observational study, we evaluated 85 patients with functional gastrointestinal symptoms and food intolerance. Gastrointestinal symptoms were classified according to Rom IV into functional abdominal pain (FAP), irritable bowel syndrome (IBS), irritable bowel syndrome diarrhea dominant (IBS-D), irritable bowel syndrome constipation dominant (IBS-C), irritable bowel syndrome with mixed stool (IBS-M), functional abdominal bloating (FAB), functional diarrhea (FD) and unclassified (NC). During eCLE, spontaneous transfer of intravenously applied fluorescein into duodenal lumen (LGS) and following duodenal food challenge (DFC) were analyzed. Blood analysis comprised parameters of mast cell function, histology of duodenal mucosal biopsies analysis of mucosal inflammation, intraepithelial lymphocytes (IELs) as well as number, distribution and morphology of mast cells. RESULTS: 24 patients (9 IBS, 9 FAP, 3 FAB, 1 FD, 2 NC), showed LGS, 50 patients (14 IBS-D, 4 IBS-C, 3 IBS-M, 23 FAP, 3 FAB, 3 NC) had no LGS but responded to DFC and 11 patients (6 NC, 3 FAP, 1 FAB, 1 FD) had no LGS and no response to DFC. The proportion of subgroups with/or without spontaneous leakage of fluorescein (+LGS/-LGS) were IBS-LGS/IBS+LGS 67%/33%, FAP-LGS/FAP+LGS 72%/28%,FAB-LGS/FAB+LGS 50%/50%, NC-LGS/NC+LGS 60%/40%. Subgroup analysis revealed no significant differences for all parameters tested. CONCLUSION: As a proof of concept, the results of our study indicate that eCLE is a clinical useful tool to evaluate patients with disorders of the gut brain axis and those suspicious of LGS. However, the clinical significance of LGS remains unclear. The study should be an incentive to perform a randomized study including healthy controls.

Diverticulosis and diverticular disease are ranked among the most common gastroenterological diseases and conditions. While for many years diverticulitis was found to be mainly an event occurring in the elder population, more recent work in epidemiology demonstrates increasing frequency in younger subjects. In addition, there is a noticeable trend towards more complicated disease. This may explain the significant increase in hospitalisations observed in recent years. It is not a surprise that the number of scientific studies addressing the clinical and socioeconomic consequences in the field is increasing. As a result, diagnosis and conservative as well as surgical management have changed in recent years. Diverticulosis, diverticular disease and diverticulitis are a complex entity and apparently an interdisciplinary challenge. To meet theses considerations the German Societies for Gastroenterology and Visceral Surgery decided to create joint guidelines addressing all aspects in a truely interdisciplinary fashion. The aim of the guideline is to summarise and to evaluate the current state of knowledge on diverticulosis and diverticular disease and to develop statements as well as recommendations to all physicians involved in the management of patients with diverticular disease.

BACKGROUND: 2-year follow-up data from our randomised controlled trial showed that peroral endoscopic myotomy is associated with a significantly higher efficacy than pneumatic dilation as initial treatment of therapy-naive patients with achalasia. Here we report therapeutic success rates in patients treated with peroral endoscopic myotomy compared with pneumatic dilation at the 5-year follow-up. METHODS: We did a multicentre, randomised controlled trial in six hospitals in the Netherlands, Germany, Italy, Hong Kong, and the USA. Adults aged 18-80 years with newly diagnosed symptomatic achalasia (based on an Eckardt score >3) were eligible for inclusion. Patients were randomly assigned (1:1) to peroral endoscopic myotomy or pneumatic dilation using web-based randomisation with a random block size of 8 and stratification according to site. Randomisation concealment for treatment type was double blind until official study enrolment. Treatment was unmasked because of the different technical approach of each procedure. Patients in the pneumatic dilation group were dilated with a single series of 30-35 mm balloons. The need for subsequent dilations in the pneumatic dilation group, and the need for dilation after initial treatment in the peroral endoscopic myotomy group, was considered treatment failure. The primary outcome was therapeutic success (Eckardt score ≤3 in the absence of severe treatment-related complications and no need for retreatment). Analysis of the primary outcome was by modified intention to treat, including all patients randomly assigned to a group, excluding those patients who did not receive treatment or were lost to follow-up. Safety was assessed in all included patients. This study is registered at the Dutch Trial Registry, NTR3593, and is completed. FINDINGS: Between Sept 21, 2012, and July 20, 2015, 182 patients were assessed for eligibility, 133 of whom were included in the study and randomly assigned to peroral endoscopic myotomy (n=67) or pneumatic dilation (n=66). 5-year follow-up data were available for 62 patients in the peroral endoscopic myotomy group and 63 patients in the pneumatic dilation group. 50 (81%) patients in the peroral endoscopic myotomy group had treatment success at 5 years, compared with 25 (40%) in the pneumatic dilation group, an adjusted absolute difference of 41% (95% CI 25-57; p<0·0001). Reasons for failure were no initial effect of treatment (one patient in the peroral endoscopic myotomy group vs 12 patients in the pneumatic dilation group) and recurrent symptoms causing treatment failure (11 patients in the peroral endoscopic myotomy group [seven patients between 2 and 5 years] vs 25 patients in the pneumatic dilation group [nine patients between 2 and 5 years]); one patient in the pneumatic dilation group had treatment failure due to an adverse event. Proton-pump inhibitor use (mostly daily) was significantly higher after peroral endoscopic myotomy than after pneumatic dilation among patients still in clinical remission (23 [46%] of 50 patients vs three [13%] of 24 patients; p=0·008). 5-year follow-up endoscopy of patients still in clinical remission showed reflux oesophagitis in 14 (33%) of 42 patients in the peroral endoscopic myotomy group (12 [29%] grade A or B, two [5%] grade C or D) and two (13%) of 16 patients in the pneumatic dilation group (two [13%] grade A or B, none grade C or D; p=0·19). No intervention-related serious adverse events occurred between 2 and 5 years after treatment. The following non-intervention-related serious adverse events occurred between 2 and 5 years: a stroke (one [2%]) in the peroral endoscopic myotomy group; and death due to a melanoma (one [2%]) and dementia (one [2%]) in the pneumatic dilation group. INTERPRETATION: Based on this study, peroral endoscopic myotomy should be proposed as an initial treatment option for patients with achalasia. Although our study has shown that peroral endoscopic myotomy has greater long-term efficacy with a low risk of major treatment-related complications, this should not lead to abandonment of pneumatic dilation from clinical practice. Ideally, all treatment options should be discussed with treatment-naive patients with achalasia and a shared decision should be made.

Irritable bowel syndrome (IBS) is a gut-brain disorder of multifactorial origin. Evidence of disturbed serotonergic function in IBS accumulated for the 5-HT3 receptor family. 5-HT3Rs are encoded by HTR3 genes and control GI function, and peristalsis and secretion, in particular. Moreover, 5-HT3R antagonists are beneficial in the treatment of diarrhea predominant IBS (IBS-D). We previously reported on functionally relevant SNPs in HTR3A c.-42C > T (rs1062613), HTR3C p.N163K (rs6766410), and HTR3E c.*76G > A (rs56109847 = rs62625044) being associated with IBS-D, and the HTR3B variant p.Y129S (rs1176744) was also described within the context of IBS. We performed a multi-center study to validate previous results and provide further evidence for the relevance of HTR3 genes in IBS pathogenesis. Therefore, genotype data of 2682 IBS patients and 9650 controls from 14 cohorts (Chile, Germany (2), Greece, Ireland, Spain, Sweden (2), the UK (3), and the USA (3)) were taken into account. Subsequent meta-analysis confirmed HTR3E c.*76G > A (rs56109847 = rs62625044) to be associated with female IBS-D (OR = 1.58; 95% CI (1.18, 2.12)). Complementary expression studies of four GI regions (jejunum, ileum, colon, sigmoid colon) of 66 IBS patients and 42 controls revealed only HTR3E to be robustly expressed. On top, HTR3E transcript levels were significantly reduced in the sigma of IBS patients (p = 0.0187); more specifically, in those diagnosed with IBS-D (p = 0.0145). In conclusion, meta-analysis confirmed rs56109847 = rs62625044 as a risk factor for female IBS-D. Expression analysis revealed reduced HTR3E levels in the sigmoid colon of IBS-D patients, which underlines the relevance of HTR3E in the pathogenesis of IBS-D.

BACKGROUND: The present study evaluates the analysis of routine data within quality control management by means of ERCP in a tertiary center over five years. METHODS: In a retrospective study, we analyzed pseudonymized routine administrative data according § 21 KHEntgG. These data can be tracked with regard to specific indicators for all hospitals and after data revocation for each individual hospital. Indicators can be selected according to the combination of diagnoses and OPS-numbers. In the present study, the frequency of the combination of ERCP with pancreatitis (nominator) in ratio to ERCP without pancreatitis (denominator) was analyzed at the Helios Clinic Krefeld for the years 2016 to 2020. Data recruitment was done by 3M Germany. Revocation of pseudonymized data was performed by Helios. Data are expressed as absolute values, percentage, mean + SD and range. RESULTS: Overall, 1521 patients and ERCPs with 4981 procedures, including 688 papillotomies, were analyzed. In 30-70% of cases, ERCP was performed during emergency hospitalization. Forty-seven men and 52 women with ERCP-associated pancreatitis and 718 men and 504 women with ERCP without associated pancreatitis were detected. Among these, 99 patients had a combination of ERCP and pancreatitis,Forty-one percent of the patients developed pancreatitis after (n=41) and 59% before the ERCP (n=58). Emergency admission was comparable in both groups (25-83%). All patients developed post-ERCP pancreatitis within 12 hours post intervention. The course of ERCP-induced pancreatitis (n=41) was slight in most of the patients. In 30 patients an edematous, and in 9 patients an exudative pancreatitis developed. In 2 patients, a necrotizing pancreatitis was observed and one patient died. CONCLUSION: The results of our study indicate that the analysis of routine administrative data allows for the simple assessment of the complication rates of elective ERCPs, even with interventions at the naive papilla.
