OBJECTIVE
The pathogenesis of peptic ulcer diseases (PUDs) involves multiple factors, and the contribution of gut microbiota to this process remains unclear. While previous studies have associated gut microbiota with peptic ulcers, the precise nature of the relationship, whether causal or influenced by biases, requires further elucidation.
DESIGN
The largest meta-analysis of genome-wide association studies was conducted by the MiBioGen consortium, which provided the summary statistics of gut microbiota for implementation in the Mendelian randomization (MR) analysis. Summary statistics for five types of PUDs were compiled using the FinnGen Consortium R8 release data. Various statistical techniques, including inverse variance weighting (IVW), MR-Egger, weighted median (WM), weighted mode, and simple mode, were employed to assess the causal relationships between gut microbiota and these five PUDs.
RESULT
In the intestinal microbiome of 119 known genera, we found a total of 14 causal associations with various locations of PUDs and reported the potential pathogenic bacteria of et al. Among them, four had causal relationships with esophageal ulcer, one with gastric ulcer, three with gastroduodenal ulcer, four with duodenal ulcer, and two with gastrojejunal ulcer.
CONCLUSION
In this study, the pathogenic bacterial genera in the gut microbiota that promote the occurrence of PUDs were found to be causally related. There are multiple correlations between intestinal flora and PUDs, overlapping PUDs have overlapping associated genera. The variance in ulcer-related bacterial genera across different locations underscores the potential influence of anatomical locations and physiological functions.

Review
Duodenal perforation is a life-threatening condition and ideal approaches for the management of duodenal perforations are nowadays unclear, so numerous variables must be considered. Peptic ulcer disease is the most common disease determining a duodenal perforation, however, there may be other less common causes. We retrospectively analyzed all the patients who presented at our Division of General Surgery for a Duodenal Perforation, from September 2018 to December 2019. We focused on patients requiring a tube duodenostomy. Five patients were included in this study. Five patients suffering from a duodenal perforation were analyzed and their data collected. All patients were treated with tube duodenostomy, pyloric exclusion and omega loop gastro-enteroanastomosis. The duodenostomy was removed four weeks after surgery. All patients suffered postsurgical complications ranging from wound infection to pneumonitis; the incidence of severe complications was greater in the older patients. We did not record any deaths four months after the operation. The tube duodenostomy is an old and dated procedure but simple to implement, which may require an increase in post-operative hospitalization, but which subsists as an effective and safe way to treat patients in critical conditions.

Meta-Analysis
Peptic ulcer disease (PUD) refers to acid-induced injury of the digestive tract, occurring mainly in the stomach (gastric ulcer (GU)) or duodenum (duodenal ulcer (DU)). In the present study, we conducted a large-scale, cross-ancestry meta-analysis of PUD combining genome-wide association studies with Japanese and European studies (52,032 cases and 905,344 controls), and discovered 25 new loci highly concordant across ancestries. An examination of GU and DU genetic architecture demonstrated that GUs shared the same risk loci as DUs, although with smaller genetic effect sizes and higher polygenicity than DUs, indicating higher heterogeneity of GUs. Helicobacter pylori (HP)-stratified analysis found an HP-related host genetic locus. Integrative analyses using bulk and single-cell transcriptome profiles highlighted the genetic factors of PUD being enriched in the highly expressed genes in stomach tissues, especially in somatostatin-producing D cells. Our results provide genetic evidence that gastrointestinal cell differentiations and hormone regulations are critical in PUD etiology.

59-year-old man, smoker, diabetic and hypertensive. He went to the ER due to fixed abdominal pain in the epigastrium, diaphoresis, dizziness, nausea, and "coffee grounds" vomiting. On examination he presented abdominal distension and pain on palpation in the epigastrium, without peritonism. He had a BP of 235/100 mmHg and in the blood-tests, leukocytosis with neutrophilia and normal hemoglobin. An urgent abdominal CT scan was performed, identifying a 5x6 cm nodular lesion of homogeneous density attached to the wall of the second and third duodenal portions that compressed the lumen, with two vessels with active bleeding within it. Therefore, percutaneous embolization of the gastroduodenal artery was performed. Subsequently, the patient suffered an episode of severe acute pancreatitis that required ICU admission. Finally, he presented a good clinical evolution with ceasing of pain, complete reabsorption of the hematoma and resolution of the obstructive symptoms.

To investigate the computed tomography (CT) findings of chronic duodenal papilla mucositis and duodenal papillary carcinoma, and provide more imaging information for early diagnosis of duodenal malignant diseases. CT findings and clinical data of 40 patients with chronic duodenal papilla mucositis and 46 patients with duodenal papillary carcinoma were retrospectively analyzed. Observation and measuring of direct duodenal papilla signs (including size, shape, density, enhancement uniformity, etc.), indirect duodenal papilla signs (including pancreaticobiliary dilatation) and clinical indicators (including tumor markers CA19-9, CA125, CEA, blood routine white blood cell count, bilirubin, age, gender, etc.) were carried out according to CT as well as statistical analysis. There were significant differences in duodenal papilla regular morphology, age and CA19-9 ( < .05), and significant differences in duodenal papilla maximum transverse diameter, diameter of common bile duct, diameter of pancreatic duct, total bilirubin, direct bilirubin, and jaundice in duodenal papillary carcinoma group ( < 0.01). There were no significant differences in duodenal papilla enhancement uniformity, plain CT value, arterial CT value, portal CT value, enhancement uniformity, presence or not of calculus at the lower end, gender, CEA, CA125, white blood cell count, and abdominal pain with fever (all > .05). CT is helpful for the diagnosis of duodenal papilla disease, but the CT findings of patients with duodenal papillary carcinoma tend to be similar to findings of chronic duodenal papilla mucositis, which is easy to lead to misdiagnosis, so comprehensive diagnosis should be made according to the direct and indirect CT signs as well as laboratory and clinical manifestations of duodenal papilla, so as to improve the diagnosis of duodenal papillary carcinoma, and reduce missed diagnosis and misdiagnosis.

CONTEXT.—
Eosinophilic diseases of the gastrointestinal tract (EGIDs), eosinophilic gastritis (EoG), and eosinophilic duodenitis (EoD) are rarely suspected clinically and infrequently detected by pathologists.
OBJECTIVE.—
To determine whether histories of allergic or eosinophilic disorders and requests to rule out EoG and EoD affect pathologists' awareness of eosinophils in gastrointestinal biopsies.
DESIGN.—
Thirty-one community-based pathologists were given 16 sets of biopsies from gastric and duodenal mucosa with elevated eosinophils, Helicobacter pylori gastritis, atrophic gastritis, normal stomach and duodenum, lymphocytosis, and celiac disease. Participants were assigned to 3 groups: group A did not receive histories of allergic or eosinophilic conditions; group B received similar histories plus a clue of possible allergic or eosinophilic conditions; and group C received the same histories as B and was asked to rule out EoG/EoD. A list of gastric and duodenal diagnoses and a space for comments were provided. Results were analyzed descriptively.
RESULTS.—
Pathologists correctly diagnosed most noneosinophilic gastrointestinal disorders, indicating competence in gastrointestinal pathology. With respect to EoG and EoD, pathologists in group C performed significantly better that those in groups A and B. The combined odds ratio with 95% CI was 12.34 (2.87-53.04), P < .001, for A versus C and 4.02 (1.60-10.09), P < .02, for B versus C.
CONCLUSIONS.—
Most pathologists neither reported gastric/duodenal eosinophilia nor diagnosed EoG/EoD, even when provided histories of eosinophilic disorders. Requests to rule out EoG/EoD resulted in only 4 of 11 participants evaluating and counting eosinophils in some cases. Simple evidence-based histopathologic criteria are needed before pathologists can be expected to consider and diagnose EGIDs.

BACKGROUND
() infection is a risk factor for many diseases, including peptic ulcer disease and gastric cancer. While eradication therapy can prevent these diseases, potentially unfavorable effects of eradication therapy have also been reported in some diseases, such as gastroesophageal reflux disease (GERD), Barrett's esophagus (BE), inflammatory bowel disease (IBD), allergic diseases, and metabolic diseases. Consequently, both positive and negative impacts should be considered when assessing the effects of eradication therapy.
AIM
To compare the incidence of these diseases before and after eradication and to comprehensively assess its effects.
METHODS
This retrospective cohort study used a Japanese nationwide health claims database (April 2009-March 2020), developed by the Japanese Ministry of Health, Labour and Welfare. The database contained almost all health insurance claims data issued in Japan, and specific health check-up data for individuals who took the check-ups. Descriptive statistics were used for the analyses. Patients who received primary eradication therapy were defined as those prescribed medi-cation for eradication. New diagnoses, defined as incidence of upper gastrointestinal diseases and IBD, and prevalence of allergic diseases were compared before and after eradication. The incidence and prevalence of each disease were also compared between the 3-year period before eradication (from the 4 to the 2 year prior to the year of eradication) and the 3-year period after eradication (from the 1 to the 3 year after the year of eradication) based on the age category and calendar year and month. Changes in body mass index and proportion of patients with metabolic syndrome (MS) were examined before and after eradication.
RESULTS
We identified 5219731 patients who received primary eradication therapy. The 65-69 years age group had the greatest number of patients in both sexes. There was no significant increase in the incidence of GERD after eradication when considering the effects of aging and reporting period. However, the incidence of BE was higher in the 3-year period after eradication than in the 3-year period before eradication for all age categories (0.02%-0.10% < 0.01%-0.05%). The incidence of IBD and prevalence of allergic disease were also higher after eradication. In contrast, the incidence of gastric and duodenal ulcers and gastritis was reduced after eradication. In patients with at least one entry of health check-up data (1701111 patients), the percentage of patients with MS showed a slight increase following eradication (11.0% in the year of eradication and 12.2% after 5 years).
CONCLUSION
The results suggest that eradication therapy reduces peptic ulcers and gastritis; however, it is associated with increased incidence of several other chronic diseases.

BACKGROUND
Duodenal neuroendocrine tumors (dNETs) are rare, and their management is not well-defined. National Comprehensive Cancer Network (NCCN) guidelines recommend surgical resection of large dNETs (> 2 cm) and endoscopic resection of small tumors (< 2 cm). We compared the survival outcomes between surgical and endoscopic resection in various dNET sizes.
METHODS
A retrospective cohort study was conducted using patient data from Surveillance, Epidemiology, and End Results Program (SEER) database. Variables analyzed included age, tumor size, grade, stage, and lymph node status. Disease-specific survival (DSS) was compared for endoscopic and surgical groups in dNET size strata: 0-0.5, 0.5-1, 1-2, 2-3, and > 3 cm. Kaplan-Meier and multivariable Cox proportional hazards models were used for survival analysis.
RESULTS
The study included 465 patients, with 124 (26.7%) undergoing surgical resection. The average age was 61.9 years, and tumor sizes ranged from 0.1 to 10.5 cm. Endoscopic resection had 40.5% of tumors between 0 and 0.5 cm, while surgery had only 21% (p < 0.001). In the surgical cohort, 79.8% had grade 1 tumors compared to 88.3% in the endoscopy group (P = 0.024). Among surgically resected cases, 48.4% (60 patients) had lymph node involvement. Age, tumor size, grade, and stage did not significantly predict survival after surgical resection. Stratified by tumor size, no difference in DSS was observed between surgery and endoscopy groups.
CONCLUSIONS
Endoscopic resection demonstrated similar survival outcomes to surgical resection across dNET sizes in this national analysis. Given the risks and the lack of survival benefits for surgery, endoscopic resection may be beneficial for both small and large tumors. Further studies are warranted to validate the current NCCN guidelines.

BMC Gastroenterology Feb 2022The purpose of this study was to investigate the diagnosis and treatment experience of traumatic duodenal ruptures in children.
BACKGROUND
The purpose of this study was to investigate the diagnosis and treatment experience of traumatic duodenal ruptures in children.
METHODS
Clinical data were collected from four children suffering from a traumatic duodenal rupture who were admitted to and treated by our hospital from January 2012 to December 2020. The early diagnosis and treatment, surgical plan, postoperative management, complications, and prognosis of each child were analyzed. The key points and difficulties of the diagnosis and treatment for this type of injury are summarized.
RESULTS
One child had an extreme infection caused by drug-resistant bacteria, which resulted in severe complications, including wound infection, dehiscence, and an intestinal fistula. One child developed an anastomotic stenosis after the duodenostomy, which improved following an endoscopic balloon dilatation. The other two children had no relevant complications after their operations. All four patients were cured and discharged from hospital. The average hospital stay was 48.25 ± 26.89 days. The follow-up period was 0.5 to 1 year. No other complications occurred, and all children had a positive prognosis.
CONCLUSIONS
The early identification of a duodenal rupture is essential, and surgical exploration should be carried out proactively. The principles of damage-control surgery should be followed as much as possible during the operation. Multidisciplinary cooperation and management are both important to reduce the occurrence of postoperative complications and improve cure rates.

OBJECTIVES
The aim of this study was to describe the endoscopic appearance of gastroduodenal ulcers (GDUs), and to assess the clinical, ultrasonographic and histological data, as well as long-term follow-up, in cats.
METHODS
The medical record databases of five veterinary endoscopists were evaluated between January 2016 and 2020, in a retrospective study. Cats with at least one gastric or duodenal ulcer detected by endoscopic examination were included. All the medical records of the selected cats were reviewed and information was collected regarding breed, age, sex, neuter status, medical history, clinical signs, and ultrasonographic, endoscopic and histological findings. The cats were evaluated at 6, 12 and 18 months.
RESULTS
Sixty-one cats with a median age of 9.0 years (range 2.0-16.0) were included in the study. The most common complaints were vomiting (n = 55; 90%) and hyporexia (n = 40; 66%); haematemesis was reported in 12 (20%) cats. Endoscopy showed GDUs in the following locations: gastric body in 28 cats (46%), antropyloric area in 34 cats (56%), fundus in 13 cats (21%) and duodenum in eight cats (13%). A single GDU was found in 42 cats (69%) and multiple GDUs were seen in 19 cats (31%). Histopathological evaluation revealed benign lesions in 33 (54%) cats and malignant lesions in 28 (46%; 24 high-grade lymphoma, one low-grade lymphoma and three carcinoma). High-grade lymphoma was detected only in the stomach. Cats diagnosed with malignant GDUs (median 10.5, range 4-16) were significantly older than cats with benign lesions ( = 0.002).
CONCLUSIONS AND RELEVANCE
GDUs are common and were detected in 5.1% of cats undergoing an upper gastrointestinal endoscopy. The risk of a malignant ulcer increases proportionally with each year of increasing age. GDU location, number and morphological appearance do not provide any indication of the nature of the ulcer; however, duodenal ulcers are frequently benign. Endoscopic examination facilitates the early and minimally invasive detection of GDUs in cats.
