BACKGROUND
Heterotopic pancreas (HP) is an aberrant anatomic malformation that occurs most commonly in the upper gastrointestinal tract. While the majority of heterotopic pancreatic lesions are asymptomatic, many manifest severe clinical symptoms which require surgical or endoscopic intervention. Understanding of the clinical manifestations and symptoms of HP is limited due to the lack of large volume studies in the literature. The purpose of this study is to review symptomatic cases at a single center and compare these to a systematic review of the literature in order to characterize common clinical manifestations and treatment of this disease.
AIM
To classify the common clinical manifestations of heterotopic pancreas.
METHODS
A retrospective review was conducted of pathologic samples containing heterotopic pancreas from 2000-2018. Review was limited to HP of the upper gastrointestinal tract due to the frequency of presentation in this location. Symptomatic patients were identified from review of the medical records and clinical symptoms were tabulated. These were compared to a systematic review of the literature utilizing PubMed and Embase searches for papers pertaining to heterotopic pancreas. Publications describing symptomatic presentation of HP were selected for review. Information including demographics, symptoms, presentation and treatment were compiled and analyzed.
RESULTS
Twenty-nine patient were identified with HP at a single center, with six of these identified has having clinical symptoms. Clinical manifestations included, gastrointestinal bleeding, gastric ulceration with/without perforation, pancreatitis, and gastric outlet obstruction. Systemic review of the literature yielded 232 publications detailing symptomatic cases with only 20 studies describing ten or more patients. Single and multi-patient studies were combined to form a cohort of 934 symptomatic patients. The majority of patients presented with abdominal pain (67%) combined with one of the following clinical categories: (1) Dyspepsia, ( = 445, 48%); (2) Pancreatitis ( = 260, 28%); (3) Gastrointestinal bleeding ( = 80, 9%); and (4) Gastric outlet obstruction ( = 80, 9%). The majority of cases ( = 832, 90%) underwent surgical or endoscopic resection with 85% reporting resolution or improvement in their symptoms.
CONCLUSION
Heterotopic pancreas can cause significant clinical symptoms in the upper gastrointestinal tract. Better understanding and classification of this disease may result in more accurate identification and treatment of this malformation.

The objective of this systematic review was to compare the efficacy of antibiotic and non-antibiotic alternatives in the prevention and treatment of necrotic enteritis (NE) in broiler chickens. experimental and observational studies that compared the administration of non-antibiotic compounds with antibiotics to prevent or treat NE in broiler chickens and that evaluated mortality and/or clinical or subclinical NE outcome measures were eligible. Four electronic databases were searched in December 2019 and updated in October 2021. Retrieved studies were evaluated in two phases: abstract and design screening. Data were then extracted from included studies. Risk of bias was assessed by outcome following the Cochrane Risk of Bias 2.0 tool. A meta-analysis was not conducted due to heterogeneity across interventions and outcomes. The non-antibiotic and antibiotic groups were compared at the outcome level for individual studies using the mean difference and 95% confidence interval (CI) calculated from raw data. In total, 1282 studies were originally identified, and 40 were included in the final review. The overall risk of bias for the 89 outcomes was either "high" ( = 34) or "some concerns" ( = 55). Individual study comparisons showed a beneficial trend toward the antibiotic group for reduced mortality, NE lesion scores (overall, jejunum, and ileum), counts, and for most histologic measurements (duodenum, jejunum, and ileum villi height, and jejunum and ileum crypt depth). The non-antibiotic groups showed a beneficial trend for NE duodenum lesion scores and duodenum crypt depth measurements. Based on this review, there is a trend that mostly favors antibiotic compounds in preventing and/or treating NE, but the evidence also suggests no difference when comparing them with non-antibiotic alternatives. Studies assessing this research question were heterogeneous in their intervention conditions and outcomes measured, and there were key aspects of the experimental design not reported in some of the studies.

Meta-Analysis
BACKGROUND
Several studies have suggested that the mucosal protective effects of proton pump inhibitors (PPIs) do not extend beyond the duodenum; however, PPIs may cause lower gastrointestinal (LGI) injury, although these relationships have not yet been fully elucidated.
METHODS
We searched all the relevant studies published until September 2022 that examined the risk of PPIs for LGI bleeding. We performed a meta-analysis of the risk of LGI bleeding (small bowel (SB) or colorectal bleeding) between PPI users and non-users. A subgroup analysis of patients consuming aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) was also performed.
RESULTS
Twelve studies with 341,063 participants were included in this meta-analysis. The use of PPIs was associated with the risk of LGI bleeding (odds ratio [OR] [95% confidence interval [CI]] = 1.42 [1.16-1.73]; hazard ratio [HR] [95% CI] = 3.23 [1.56-6.71]). An association between PPI use and the risk of LGI bleeding was also identified in the subgroup of aspirin or NSAID users (OR [95% CI] = 1.64 [1.49-1.80]; HR [95% CI] = 6.55 [2.01-21.33]). In the bleeding site-specific analyses, the risk of SB bleeding was associated with PPI use (OR [95% CI] = 1.54 [1.30-1.84]).
CONCLUSIONS
PPI use was associated with an increased risk of LGI bleeding, particularly SB bleeding. This association was particularly pronounced among aspirin and NSAID users. Inappropriate PPI prescriptions should be avoided in patients with LGI bleeding and a low risk of upper gastrointestinal disease.

Meta-Analysis Review
Efficacy of endoscopic preventive procedures to reduce delayed adverse events after endoscopic resection of superficial nonampullary duodenal epithelial tumors: a meta-analysis of observational comparative trials.
BACKGROUND AND AIMS
Although various procedures have been used to prevent serious adverse events after endoscopic resection of the duodenum, their effectiveness has not been determined. In this study, we conducted a systematic review and meta-analysis to determine whether endoscopic preventive procedures reduce delayed adverse events.
METHODS
Studies on endoscopic treatment for superficial nonampullary duodenal tumors were selected. We compared the following 2 groups: the closure group, which underwent mucosal sutures and coverage of mucosal defects after resection, and the unclosed group, which did not. The primary outcome was the rate of delayed adverse events, including perforation and bleeding. The pooled risk ratios (RRs) of all outcomes investigated, the 95% confidence intervals (CIs), and P values were calculated.
RESULTS
A total of 438 patients from 4 studies were included in the meta-analysis. The pooled overall adverse event rates in the closure group and unclosed group were 3.6% and 21.1%, respectively. This rate was significantly lower in the closure group (RR, 0.19; 95% CI, 0.10-0.38; P < .01; I = 0%), and the rate of delayed bleeding was significantly lower in the closure group (RR, 0.14; 95% CI, 0.06-0.33; P < .01; I = 0%). Regarding delayed perforation, the RR in the closure group was 0.39 (95% CI, 0.12-1.32; P = .13; I = 0%).
CONCLUSIONS
Preventive procedures significantly reduced the risk of delayed adverse events by more than 80%. After endoscopic resection of the duodenum, the implementation of preventive procedures, including mucosal sutures and coverage of mucosal defects, to delay adverse events is strongly recommended.

Review
BACKGROUND
Satoyoshi syndrome (SS) [OMIM 600705; ORFHA 3130] is a multisystemic disease with a probable autoimmune basis, whose main symptoms are muscle spasms, alopecia, diarrhea and skeletal alterations. Chronic diarrhea may be severe and result in malnutrition, anemia, growth retardation, cachexia, disability and even death. However, to date, no review of the digestive symptoms has been carried out.
METHODS
A search was performed in MEDLINE, Scopus and Web of Science databases. Cases of SS, without language or date restrictions, were recorded. Sixty-seven cases of SS were found up until December 2019. Thirty-nine cases described gastrointestinal manifestations.
RESULTS
Chronic diarrhea was the main digestive symptom (92.3%). Other symptoms such as abdominal pain (15.4%), nausea (7.7%) and vomiting (7.7%), were less frequent. The D-xylose test was positive in 10 out of 12 patients, and 9 out of 13 cases showed a flattened oral glucose tolerance test suggesting carbohydrate malabsorption. Antinuclear antibodies were detected in 8 out of 16 cases. Antibodies to stomach or duodenum tissue lysates were also detected by Western blot. Histological data revealed predominantly lymphoplasmacytic inflammatory infiltrate that can affect any section of the digestive tract. In 6 out of 10 patients, diarrhea improved with a treatment regimen that included corticosteroids. Other treatments, such as methotrexate, carbohydrate restricted diets or otilonium bromide, improved digestive symptoms in isolated patients. Improvement of symptoms up to three years of follow-up has been described. None of the three patients who died had received corticosteroids or immunosuppressants.
CONCLUSION
Chronic diarrhea with malabsorption is one of the most disabling symptoms in SS. The early recognition of this disease is essential for immunosuppressive treatment and a better outcome.

Meta-Analysis
INTRODUCTION
Individuals with familial adenomatous polyposis (FAP) have an almost 20% lifetime risk of duodenal adenocarcinoma, currently the leading cause of death in FAP. The Spigelman staging system provides guidance on the surveillance intervals and timing of prophylactic surgery. Still, its accuracy in predicting duodenal and papillary cancer development has not been systematically evaluated. We investigated the sensitivity and cancer risk of the Spigelman stages.
METHODS
We performed a systematic review on PubMed, MEDLINE, EMBASE, and Cochrane and used a random-effects model to pool effect sizes.
RESULTS
After removing duplicate entries, we screened 1,170 records and included 27 studies for quantitative analysis. Once duodenal polyposis reaches Spigelman stage IV, the risk of duodenal and papillary cancers increased to 25% (95% confidence interval [CI] 12%-45%). However, the sensitivity of Spigelman stage IV for these cancers was low (51%, 95% CI 42%-60%), especially for papillary adenocarcinoma (39%, 95% CI 16%-68%). We investigated the reasons behind these low values and observed that duodenal cancer risk factors included polyps >10 mm, polyp count >20, and polyps with high-grade dysplasia. Risk factors associated with papillary cancer included a papilla with high-grade dysplasia or >10 mm. The evidence on other risk factors was inconclusive.
DISCUSSION
The current Spigelman staging system had a low sensitivity for duodenal and papillary adenocarcinomas. Two Spigelman variables (duodenal villous histology and polyp count) and the lack of papilla-specific variables likely contributed to the low sensitivity values for duodenal and papillary cancers, respectively. While clinicians may be familiar with its current form, there is an urgent need to update it.

Meta-Analysis
Long-term Metabolic Morbidity and Steatohepatosis Following Standard Pancreatic Resections and Parenchyma-sparing, Local Extirpations for Benign Tumor: A Systematic Review and Meta-analysis.
OBJECTIVE
To assess metabolic dysfunctions and steatohepatosis after standard and local pancreatic resections for benign and premalignant neoplasms.
SUMMARY OF BACKGROUND DATA
Duodenopancreatectomy, hemipancreatectomy, and parenchyma-sparing, limited pancreatic resections are currently in use for nonmalignant tumors.
METHODS
Medline, Embase, and Cochrane libraries were searched for studies reporting measured data of metabolic functions following PD, pancreatic left resection (PLR), duodenum-sparing pancreatic head resection (DPPHR), pancreatic middle segment resection (PMSR), and tumor enucleation (TEN). Forty cohort studies comprising data of 2729 patients were eligible.
RESULTS
PD for benign tumor was associated in 46 of 327 patients (14.1%) with postoperative new onset of diabetes mellitus (pNODM) and in 109 of 243 patients (44.9%) with postoperative new onset of pancreatic exocrine insufficiency measured after a mean follow-up of 32 months. The meta-analysis displayed pNODM following PD in 32 of 204 patients (15.7%) and in 10 of 200 patients (5%) after DPPHR [P < 0.01; OR: 0.33; (95%-CI: 0.15-0.22)]. PEI was found in 77 of 174 patients following PD (44.3%) and in 7 of 104 patients (6.7%) following DPPHR (P < 0.01;OR: 0.15; 95%-CI: 0.07-0.32). pNODM following PLR was reported in 107 of 459 patients (23.3%) and following PMSR 23 of 412 patients (5.6%) (P < 0.01; OR: 0.20; 95%-CI: 0.12-0.32). Postoperative new onset of pancreatic exocrine insufficiency was found in 17% following PLR and in 8% following PMSR (P < 0.01). pNODM following PPPD and tumor enucleation was observed in 19.7% and 5.7% (P < 0.03) of patients, respectively. Following PD/PPPD, 145 of 608 patients (23.8%) developed a nonalcoholic fatty liver disease after a mean follow-up of 30.4 months. Steatohepatosis following DPPHR developed in 2 of 66 (3%) significantly lower than following PPPD (P < 0.01).
CONCLUSION
Standard pancreatic resections for benign tumor carry a considerable high risk for a new onset of diabetes, pancreatic exocrine insufficiency and following PD for steatohepatosis. Parenchyma-sparing, local resections are associated with low grade metabolic dysfunctions.

BACKGROUND
Inflammatory bowel disease, including ulcerative colitis, microscopic colitis, and Crohn's disease (CD), has a global impact. This review focuses on duodenal CD (DCD), a rare subtype affecting the duodenum. DCD's rarity and asymptomatic nature create diagnostic challenges, impacting prognosis and patient well-being. Delayed diagnosis can worsen DCD outcomes.
AIM
To report a rare case of DCD and to discuss the diagnostic challenges and its implications on prognosis.
METHODS
A systematic literature search, following the PRISMA statement, was conducted. Relevant studies were identified and analysed using specific Medical Subject Terms (MeSH) from PubMed/MEDLINE, American Journal of Gastroenterology, and the University of South Wales database. Data collection included information from radiology scans, endoscopy procedures, biopsies, and histopathology results.
RESULTS
The review considered 8 case reports and 1 observational study, involving 44 participants diagnosed with DCD, some of whom developed complications due to delayed diagnosis. Various diagnostic methods were employed, as there is no gold standard workup for DCD. Radiology scans [magnetic resonance imaging (MRI), computed tomography (CT), and upper gastrointestinal X-ray], endoscopy procedures (colonoscopy and esophagogastroduodenoscopy), biopsies, and clinical suspicions were utilized.
CONCLUSION
This review discusses DCD diagnosis challenges and the roles of CT, MRI, and fluoroscopy. It notes their limitations and compares findings with endoscopy and histopathology studies. Further research is needed to improve diagnosis, emphasizing scan interpretation, endoscopy procedures, and biopsies, especially in high-risk patients during routine endoscopy.

Review
PURPOSE
Long-term follow-up of congenital duodenal obstruction patients often falls on care providers with little experience of this condition. We performed a systematic review of the long-term outcomes of duodenal obstruction and provide a summary of sequelae care providers should anticipate.
METHODS
In 2022, after registering with PROSPERA, Medline (Ovid), EMBASE, PSYCHINFO, CNAHL and SCOPUS databases were searched using the title keyword 'intestinal atresia'. Abstracts were filtered for inclusion if they included the duodenum. Papers of filtered abstracts were included if they reported post-discharge outcomes. Methodological Index for Non-Randomized Studies was used to grade the papers.
RESULTS
Of the 1068 abstracts were screened, 32 papers were reviewed. Eleven studies were included. Thirty additional papers were included after reviewing references, for a total of 41 papers. The average MINORS was 7/16.
CONCLUSION
There is good evidence that children with congenital duodenal obstruction do well in terms of survival, growth and general well-being. Associated cardiac, musculoskeletal and renal anomalies should be ruled-out. Care providers should be aware of anastomotic dysfunction, blind loop syndrome, bowel obstruction and reflux. Reflux may be asymptomatic. Laparoscopic repair does not change long-term outcomes, and associated Trisomy 21 worsens neurodevelopmental outcomes.

Review
This systematic review evaluates the efficacy of surgical interventions in improving the quality of life for patients with chronic pancreatitis (CP). A thorough literature search, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, identified 11 studies that focused on patient-reported outcomes after surgical treatments, including pancreatic resections, drainage procedures, and duodenum-preserving head resections. The findings indicate that organ-preserving procedures, notably the Frey and Beger operations, significantly enhance pain control and overall quality of life while reducing analgesic dependency. This review provides crucial insights into the long-term efficacy and comparative benefits of different surgical approaches, highlighting the need for personalized surgical strategies in CP management. It emphasizes the necessity for standardized outcome measures and further comparative research to refine CP treatment protocols.
