INTRODUCTION
Endoscopic bariatric and metabolic therapies can potentially reproduce similar gastric and small intestinal anatomic and physiologic manipulations as Roux-en-Y gastric bypass. This proof of concept animal study was aimed to assess the feasibility, safety, efficacy, and impact on gastrointestinal physiology of combined intragastric balloons (IGB) and duodenal-jejunal bypass liner (DJBL) for the treatment of obesity.
METHODS
Five Ossabaw pigs were fed a high-calorie diet to develop obesity and were randomly assigned to receive IGB or DJBL in sequence. The weight gain rate was calculated. Fasting and postprandial blood samples were drawn before any intervention (serving as the baseline group) and 1 month after second device insertion (serving as the combination group) to measure gut neurohormonal changes and metabolic parameters.
RESULTS
Four pigs successfully received a sequential device insertion. One pig developed duodenal sleeve prolapse that was spontaneously resolved. One pig was early terminated because of developing a central line infection. The rate of weight gain in the combination group (0.63 ± 1.3 kg/wk) was significantly lower than the baseline group (1.96 ± 2.17 kg/wk) and numerically lower than after insertion of the IGB (1.00 ± 1.40 kg/wk) or the DJBL (0.75 ± 2.27 kg/wk) alone. A trend of higher postprandial glucagon-like peptide-1 was observed in the combination group compared with the baseline group.
DISCUSSION
A combination of IGB and DJBL is feasible and well tolerated. A strategy of sequential use of these devices might offer a synergistic approach that can enhance weight loss and metabolic outcomes.

INTRODUCTION
Adult-onset autoimmune enteropathy (AIE) is a rare cause of severe chronic diarrhea because of small intestinal villous atrophy. We report on patients with adult-onset AIE in an European referral center.
METHODS
Retrospective study including patients diagnosed with AIE in the Amsterdam UMC, location VUmc, between January 2003 and December 2019. Clinical, serological, and histological features and response to treatment were reported. The specificity of antienterocyte antibodies (AEA) was evaluated by examining the prevalence of AEA in (i) controls (n = 30) and in patients with (ii) AIE (n = 13), (iii) celiac disease (CD, n = 52), (iv) refractory celiac disease type 2 (n = 18), and (v) enteropathy-associated T-cell lymphoma (EATL, n = 10).
RESULTS
Thirteen AIE patients were included, 8 women (62%), median age of 52 years (range 23-73), and 6 (46%) with an autoimmune disease. AEA were observed in 11 cases (85%), but were also found in CD (7.7%), refractory celiac disease type 2 (16.7%), and EATL (20%). Ten patients (77%) were human leukocyte antigen DQ2.5 heterozygous. Total parenteral nutrition was required in 8 cases (62%). Steroids induced clinical remission in 8 cases (62%). Step-up therapy with rituximab, cyclosporine, infliximab, and cladribine in steroid-refractory patients was only moderately effective. Four patients died (31%), but 4 (31%) others are in long-term drug-free remission after receiving immunosuppressive treatment, including 1 patient who underwent autologous stem cell transplantation.
DISCUSSION
Adult-onset AIE is a rare but severe enteropathy that occurs in patients susceptible for autoimmune disease. Four patients (31%) died secondary to therapy-refractory malabsorption, while immunosuppressive therapy leads to a long-lasting drug-free remission in one-third of patients.

Journal of Veterinary Internal Medicine Mar 2023Angiodysplasia (AGD) is rarely diagnosed in dogs with gastrointestinal bleeding (GIB) and is reported in case reports in dogs.
BACKGROUND
Angiodysplasia (AGD) is rarely diagnosed in dogs with gastrointestinal bleeding (GIB) and is reported in case reports in dogs.
OBJECTIVE
Describe signalment, clinical and diagnostic features of dogs with gastrointestinal (GI) AGD diagnosed by video capsule endoscopy (VCE).
ANIMALS
Dogs with overt or suspected GIB which underwent VCE.
METHODS
Dogs for which a VCE was submitted for overt or suspected GIB from 2016 to 2021 were selected retrospectively. Medical records and full-length VCE recordings where AGDs were initially detected, were reviewed by 2 trained internists. AGD was considered definitive if 2 readers detected it. Signalment, clinical signs, blood work, medications, concurrent diseases, findings of previous conventional endoscopy, and surgical exploration (if applicable) of dogs with AGD were recorded.
RESULTS
Definitive AGD was diagnosed in 15 of 291 (5%) dogs (12 males, 3 females). Twelve (80%) had overt GIB, 11 (73%) had hematochezia, and 6 (40%) had microcytic and hypochromic anemia. AGD was missed by conventional endoscopy in 9/9 dogs and exploratory surgery in 3/3 dogs. Thirteen capsules were administered by mouth (1 incomplete study), and 2 via endoscopy directly into the duodenum. AGD was visualized in the stomach of 3 dogs, in the small intestine of 4, and in the colon of 13 dogs.
CONCLUSION AND CLINICAL IMPORTANCE
Although rare, AGD should be considered in dogs with suspected GIB after a negative conventional endoscopy or surgical exporation. Video capsuel endoscopy appears to be a sensitive test to identify AGD within the GI tract.

BACKGROUND
Hospitalization for peptic ulcer disease (PUD) has been described outside of North America as peaking in the fall and winter. However, no recent literature has so far investigated the seasonal fluctuations and complications of PUD in the USA. Cross-sectional population database review.
METHODS
Patients with a diagnosis of either acute gastric or acute duodenal ulcers from January 1, 2015, through December 31, 2017, were identified in the Healthcare Cost and Utilization Project's National Inpatient Sample. The proportion of admissions with either hemorrhage or perforation was determined for each season and further subdivided into geographic regions.
RESULTS
Of 18829 hospitalizations for PUD, admissions were the highest in the fall (25.9%) while being the lowest in the summer (23.9%). Complications, hemorrhage or perforation, were the highest and the lowest in the fall and spring, respectively (75.7% vs. 73.6%; =0.060 for comparing all 4 seasons). Geographically, the West had the highest rate of peptic ulcer hemorrhage (64.5%, =0.004), while the northeast had the highest rate of perforation (14.3%, =0.003). Hemorrhage was more common in males, those who used aspirin, nonsteroidal anti-inflammatory drugs, or anticoagulants, and diabetics (<0.05). Perforation was less common in males, those with diabetes, obesity, or hypertension (HTN), or those using aspirin or anticoagulants (<0.05). infection was more associated with perforation in the fall and winter months.
CONCLUSION
Seasonal and regional trends in hospitalizations due to PUD may help identify modifiable risk factors, which can improve diagnostic and treatment outcomes for patients by allowing for more targeted identification of vulnerable populations.

Observational Study
INTRODUCTION
It is unclear how immune perturbations may influence the pathogenesis of idiopathic gastroparesis, a prevalent functional disorder of the stomach which lacks animal models. Several studies have noted altered immune characteristics in the deep gastric muscle layer associated with gastroparesis, but data are lacking for the mucosal layer, which is endoscopically accessible. We hypothesized that immune dysregulation is present in the gastroduodenal mucosa in idiopathic gastroparesis and that specific immune profiles are associated with gastroparesis clinical parameters.
METHODS
In this cross-sectional prospective case-control study, routine endoscopic biopsies were used for comprehensive immune profiling by flow cytometry, multicytokine array, and gene expression in 3 segments of the stomach and the duodenal bulb. Associations of immune endpoints with clinical parameters of gastroparesis were also explored.
RESULTS
The gastric mucosa displayed large regional variation of distinct immune profiles. Furthermore, several-fold increases in innate and adaptive immune cells were found in gastroparesis. Various immune cell types showed positive correlations with duration of disease, proton pump inhibitor dosing, and delayed gastric emptying.
DISCUSSION
This initial observational study showed immune compartmentalization of the human stomach mucosa and significant immune dysregulation at the level of leukocyte infiltration in idiopathic gastroparesis patients that extends to the duodenum. Select immune cells, such as macrophages, may correlate with clinicopathological traits of gastroparesis. This work supports further mucosal studies to advance our understanding of gastroparesis pathophysiology.

Gallstone ileus is a rare complication of cholelithiasis, characterized by mechanical bowel obstruction due to a biliary calculus originating from a bilioenteric fistula. The Rigler triad, consisting of aerobilia, ectopic gallstone, and intestinal obstruction, is rarely observed in its complete form. We present the case of a 92-year-old male with a history of acute lithiasic cholecystitis who presented to the Emergency department with acute epigastric pain. Initial evaluation revealed gallbladder dilatation, gallstones, and gallbladder wall thickening suggestive of acute cholecystitis. During hospitalization, the patient experienced an episode of hematemesis, leading to the diagnosis of a cholecystoduodenal fistula and a large blood clot in the duodenal bulb. Further imaging showed an ectopic gallstone causing small bowel obstruction. The patient underwent urgent surgery for stone extraction, followed by endoscopic intervention for the bleeding vessel identified at a subsequent gastroscopy. Unfortunately, the patient had a poor postoperative course and passed away seven days later. This case report highlights the exceptional occurrence of both the Rigler triad and upper gastrointestinal bleeding in a patient with gallstone ileus. Surgical intervention is crucial for the initial resolution of intestinal obstruction, followed by cholecystectomy and repair of the bilioenteric fistula. Awareness of these rare presentations is important for timely diagnosis and appropriate management of this uncommon complication of cholelithiasis.

BACKGROUND
Duodenal fibrolipoma and duodenum-jejunum intussusception are both rare occasions in clinical practice. The diagnosis of duodenal fibrolipoma mainly depends on endoscopy examination, supplemented by CT and MRI. As the tumor grows, some severe symptoms need surgical intervention. As the development of endoscopic techniques, the operation plan should be made individually.
CASE PRESENTATION
A 47-year-old female with the complaint of upper abdominal pain and melena was reported. Abdominal examination revealed upper abdomen lightly tender and blood test showed severe anemia. Image and endoscopy examination exhibited "a giant mass" in the descending (D2) part of duodenum, dragged by the tumor into the distal intestinal canal and causing intussusception. Intermittent blood transfusion treatment, enteral and parenteral nutrition were adopted to adjust her general state. Two weeks later, the mass was resected together with the basement intestinal wall via the jejunum incision and then the intussuscepted D2 part was restored. The paraffin pathological diagnosis correlated with the preoperative judgment of fibrolipoma and the patient was discharged healthy on POD 14.
CONCLUSIONS
Duodenal fibrolipoma is a rare disease, infrequently causing intussusception and severe upper GIB. Duodenoscopy and endoscopic ultrasound contribute to making an appropriate diagnosis, and for patients with severe symptoms needed surgical intervention, operation plan should be individualized depending on the size and location of the lesion.

Comparative Study
BACKGROUND AND AIMS
In recent years, with the development of endoscopic techniques, endoscopic resection is widely used for duodenal papillary adenomas, but conventional endoscopic resection has a high rate of incomplete resection and recurrence. On this basis, we have employed a novel modified endoscopic papillectomy (ESP). In this study, we evaluated the feasibility and advantages of this ESP for the treatment of duodenal major papilla adenoma.
METHODS
A total of 56 patients with duodenal major papilla adenoma confirmed by endoscopic ultrasonography, intraluminal ultrasound and gastroscopic biopsy from October 2007 to June 2017 were collected in the Department of Gastroenterology, Nanjing Drum Tower Hospital. The diameter of the adenoma ranged from 1.41 to 2.02 cm. 16 cases were given the conventional method and 40 cases underwent the modified ESP procedure in which a small incision was made by cutting current when anchoring the snare tip on the distal side of the adenoma.
RESULTS
En bloc resection rate was significantly higher in the modified group (100%, 40/40) than that in the conventional group (81.3%, 13/16; P = 0.02). However, no significance was seen between the modified group and the conventional group in complete resection rate (92.5%, 37/40 vs 93.8%, 15/16; P = 1.00). There was no significant difference in the number and difficulty of postoperative pancreatic and biliary stents placement between the two groups (P = 0.20). Total bleeding occurrence was much lower in the modified group (37.5%, 15/40 vs 87.5%, 14/16; P = 0.001), and no significant differences were found in other short-term complications and the 3, 6, 12 and 24 months recurrences rate between the conventional and modified ESP groups.
CONCLUSIONS
The modified ESP improves the treatment outcome of duodenal major papilla adenoma with higher en bloc resection rate and lowering bleeding rate.

OBJECTIVE
Gastrointestinal bleeding (GIB) is an uncommon complication after abdominal surgery. Given the unique risks in the total pancreatectomy with islet autotransplant (TPIAT) population, we aimed to describe this population's incidence of postoperative GIB.
METHODS
Prospectively collected data on patients who underwent a TPIAT from 2001 to 2018 at the University of Minnesota were reviewed for postoperative GIB. Each GIB patient was matched to a control patient and compared for medical, medication, and social history and for clinical outcomes.
RESULTS
Sixty-eight patients developed a GIB (12.4%) at median time after surgery of 17 months. Etiologies included the following: anastomotic ulcer (35%), Clostridium difficile (4%), gastric or duodenal ulcers (9%), esophagitis/gastritis (10%), hemorrhoids (3%), inflammatory bowel disease (4%), Mallory-Weiss tears (1%), and unknown (29%). During diagnostic workup, 87% had an endoscopic procedure and 3% underwent imaging. Seven patients required an operation (10%), 1 required an open embolization (1%), and 13 required endoscopic treatments (19%). Patients with a GIB were more likely to die (15% vs 5%, P = 0.055).
CONCLUSIONS
Twelve percent of patients developed a GIB after TPIAT. One third of those had an undefined etiology despite endoscopy. The need for intervention was high (30%).

Duodenal ulcer significantly reduces quality of life and safety in children; however, the mechanism of the pathogenesis in children with duodenal ulcer remains unclear. S100A8/A9, which plays a critical role in the occurrence and development of inflammation, has attracted a lot of interest recently. Here, we identified that S100A8/A9 are highly expressed in the serum of children with duodenal ulcers, and this is of excellent diagnostic value. Animal experiments have proved that inhibition of S100A8/A9 can repair ulcer progression. In addition, further study has shown that S100A8/A9, mainly produced by neutrophil, can enhance the apoptosis of intestinal epithelial cells and promote the growth in children with duodenal ulcers. Thus, our research proves the value of S100A8/A9 in the diagnosis and treatment of children with duodenal ulcers.
