Crohn's disease (CD), also known as cicatrizing enteritis, is an inflammatory bowel disease that occurs in the distal ileum and right colon of unknown cause and is also called inflammatory bowel disease (IBD) with ulcerative colitis (UC). In recent years, intestinal biota have been confirmed to play a significant role in various gastrointestinal diseases. Studies have found that intestinal microbiota disorders are closely associated with the onset and progression of Crohn's disease. Bacteroidetes, the second largest microbiota in the intestine, are crucial for equilibrium in the microbiota and intestinal environment. Certain Bacteroides can induce the development of Crohn's disease and aggravate intestinal inflammation directly or through their metabolites. Conversely, certain Bacteroides can reduce intestinal inflammation and symptoms of Crohn's disease. This article reviews the effect of several intestinal Bacteroides in the onset and progression of Crohn's disease and their impact on its treatment.

We present the case of a 70-year-old patient of Caucasian origin under palliative chemotherapy for metastasized colorectal cancer, who presented with signs of complete small bowel obstruction six months after placement of a diverting ileostomy. Following previous tumor perforation, he was not considered a candidate for further surgical intervention.Thus, endoscopic ultrasound-guided enterocolostomy (i.e., ileosigmoidostomy) with a lumen-apposing metal stent was successfully performed in a coloenteric approach to restore the passage.Oral nutrition could be resumed the next day, and the patient could be discharged in substantially improved condition after three days.

AL-Amyloidosis is a rare systemic disease that can occur in patients with monoclonal gammopathy or multiple myeloma. As multiple organs may be affected by deposition of amyloid fibrils, the clinical presentation varies considerably, and the diagnostic process may be challenging.We report on a 59-year-old female who suffered from gastroesophageal reflux symptoms, nausea, epigastric pain, and meteorism over several years. Repeated upper GI endoscopies including biopsies and CT scans were unremarkable except for unspecific enlargement of mesenterial lymph nodes.A few weeks after a surgical hiatal hernia repair with fundoplication, the patient developed massive distension of the stomach and the proximal duodenum resulting in gastric perforation. Histopathological staining of gastric biopsies and mesenterial lymph nodes using hematoxylin and eosin was unremarkable. Because of endoscopic findings (submucosal hematomas, and ulcerations) and the unexplained severe motility disorder, histopathological staining was performed using Congo red. Extensive amyloid deposits were seen. Further workup confirmed AL amyloidosis caused by monoclonal gammopathy. Specific oncological treatment was started.The rare differential diagnosis of amyloidosis should be taken into account in patients with unexplained motility disorders, unspecific gastrointestinal symptoms, and abdominal lymphadenopathy. In the presented case, delayed diagnosis of AL amyloidosis in the gastrointestinal tract led to severe gastroparesis resulting in gastric perforation. Specific histopathologic staining can confirm the diagnosis.

Real-world data on the management of patients with primary biliary cholangitis (PBC) are so far scarce in Germany. Therefore, we aimed to establish a nationwide registry and describe the clinical characteristics and therapy of PBC patients.Three different cohorts defined as ursodeoxycholic acid (UDCA) responders, as inadequate responders according to Paris II criteria, and as newly diagnosed patients were prospectively recruited.This manuscript includes the baseline data of the project.In total, 33/77 (43%) contacted centres (58% of university hospitals, 38% of non-university hospitals, and 24% of private practices) recruited 515 patients including 204 UDCA responders, 221 inadequate responders to UDCA, and 90 newly diagnosed patients.All patients were treated with UDCA; however, a UDCA dosage below the recommended dosage of 13 mg/kg/d was observed in 38.5% of individuals after 12 months of treatment. UDCA dosages were lower in nonacademic compared to academic centres.Only 75/219 (38.5%) of inadequate responders to UDCA received a second-line therapy with obeticholic acid (OCA) and/or bezafibrate (BZF). OCA (13% vs. 4.5%) and BZF (14% vs. 6.5%) were significantly more often prescribed by academic vs. nonacademic centres.Pruritus (27% vs. 15.5%), fatigue (23% vs. 4.5%), and sicca syndrome (14% vs. 1%) were significantly more often reported by academic centres.The German PBC registry could be established, which indicates suboptimal therapy in a relevant proportion of patients and shows significant differences between academic and nonacademic centres. Results are fundamental to improving clinical management at different levels of care.

Granular cell tumors, uncommon soft tissue growths, predominantly manifest in the subcutaneous and tongue areas, while those in the gastrointestinal tract are scarce and develop slowly. Patients typically show no distinct clinical symptoms and are hard to differentiate from gastrointestinal mesenchymal tumors, smooth muscle tumors, neural sheath tumors, and rhabdomyosarcomas using endoscopy. This paper details a case of a granular cell tumor in the stomach addressed through endoscopic submucosal dissection, focusing on its endoscopic attributes and clinicopathological traits.

Based on new insights into the aetiology and pathogenesis of gastric marginal-zone B-cell lymphoma of MALT (MALT-lymphoma) and its histomorphological and molecular characteristics, important progress in our understanding of the disease and its clinical management has been made during the last decades. A landmark in this development was the identification of Helicobacter pylori as the decisive pathogenetic factor for gastric MALT lymphoma. We, here, give an overview about the history and the current knowledge of the histology, genetics, and molecular characteristics and pathogenesis of gastric MALT lymphoma. We then focus on how these findings have fundamentally changed its clinical management over the last three decades with consequent deescalating therapeutic strategies.

Background and objectives: Diagnosis and therapy of peristomal skin lesions are challenging for the majority of therapists. Established diagnostic tools have not yet been validated. Our objective was to outline the spectrum of and to identify risk factors for skin lesions in ostomy patients. A focus was set on peristomal ulcerations and their differentiation as peristomal pyoderma gangrenosum.

Methods: In a retrospective analysis, frequency and character of peristomal skin lesions in patients presenting at two departments were analysed. Patients suffering from peristomal ulcerations were subjected to a more detailed analysis including application of the PARACELSUS score.

Results: A total of 565 patients with ostomy were analysed; 40.2% (n = 227) presented with peristomal skin lesions. Moisture-associated skin damage (27.9%) was the most common, while ulcerations (21.9%) and eczematous skin alterations (19.1%) were seen with comparable frequency. Peristomal pyoderma gangrenosum was diagnosed in 7.9% of all observed peristomal lesions. Among patients with inflammatory bowel disease (n = 98), peristomal ulcerations were the leading finding (35.7%), and pyoderma gangrenosum was more frequent in these patients (16.3%).

Conclusions: It is necessary to assess and classify peristomal skin lesions. Further studies for the validation of different scores or the development of diagnostic tools are needed.

Background: Idiopathic and secondary megacolon (MC) and megarectum (MR) in adults is associated with persistent bowel dilatation and reduced intestinal motility. Little is known about the optimal treatment of this rare disease. Therefore, we retrospectively analysed long-term data from these patients in 5 community and university hospitals, focusing on conservative versus surgical treatment.

Methods: Patient records from 7/2004 to 9/2021 were screened for colorectal diseases with severe constipation and persistent megacolon ≥ 9.0 cm and/or megarectum ≥ 6.5 cm. Follow up-data was collected through telephone interviews and written surveys. ClinicalTrialsgov NCT04340856.

Results: Sixty-seven patients with idiopathic (n=10) and secondary (n=57) MC or MR were identified with only 20 of 67 patients (29.9%) correctly diagnosed. Mean/median age was 64/69 (range 18-93) years. Thirty-two patients were treated with laxative regimens, and 35 underwent surgery (colostomy: n=12, segmental resection, or hemicolectomy: n=10, (sub)total colectomy: n= 13) after conservative treatment attempts in 32/35 (91.4%). The mean/median follow-up was 4.2/2.7 (range 0.1-17.0) years. The readmission rate for MC-associated symptoms was significantly higher after conservative treatment than after surgical therapy at 12 (0.84 vs. 0.36 per patient, p=0.036), 24 (1.00 vs. 0.52, p=0.048) and 36 (1.13 vs. 0.58, p=0.047) months, as was the number of patients with persistent laxative dependence (28/32 (87.5%) vs. 19/33 (57.6%); p = 0.007). Therapy-associated adverse events (Clavien-Dindo classification) were documented more often in surgically treated patients (11/35, 31.4%) (p=0.025).

Conclusion: Surgical treatment may be considered earlier if idiopathic or secondary MC or MR is correctly diagnosed, and conservative treatment has been attempted.
