RESUMO
BACKGROUND: Spontaneous pancreatic portal vein fistula (PPVF) - a rare complication of pancreatic inflammation - varies widely in presentation and means of diagnosis but has been previously associated with bleeding complications and mortality. A systematic review of published literature was performed to assess the frequency of outcomes. METHODS: A search of electronic databases (PubMed, Ovid MEDLINE, Scopus, EMBASE, gray literature) resulted in 1667 relevant unique manuscripts; 52 met inclusion criteria. RESULTS: A total of 74 unique (male n = 47, 63.5 %) patients were included. Mean age was 53.5 (±11.9) years. History of alcohol use was reported in 55 (74.3 %). Underlying chronic pancreatitis (CP) was present in 49 (66.2 %). In cases where presenting symptoms were reported (n = 57, 77.4 %), the most frequent were abdominal pain (63.5 %), weight loss (14.9 %), rash (12.2 %), nausea/vomiting (12.2 %), and polyarthritis (9.5 %). Computed tomography was the most common imaging modality used to confirm the diagnosis (n = 20, 27.0 %), followed by magnetic resonance cholangiopancreatography (n = 14, 18.9 %). Portal vein thrombosis was reported in 57 (77.0 %), and bleeding events (luminal, variceal, or intra-pseudocyst) were reported in 13(17.6 %) patients. Younger age was associated with higher risk of bleeding events. Mortality was reported in 12 (16.2 %) patients at any time during follow up. Older age and polyarthritis at presentation were associated with mortality. CONCLUSIONS: PPVF is a rare and potentially fatal condition, though rates of bleeding complication and death were relatively low in this population. High-quality observational studies are needed to better understand the pathophysiology and natural history of this diagnosis.
RESUMO
BACKGROUND: This retrospective study, conducted using the U.S. National Inpatient Sample (NIS), examines the outcomes and management of nonvariceal upper gastrointestinal bleeding (NVUGIB) in COVID-19 patients and identifies predictive factors to enhance patient prognosis. METHODS: We analyzed the 2020 U.S. NIS data involving adult patients (≥18 years) admitted with NVUGIB and categorized them based on the presence of COVID-19. Primary and secondary outcomes, NVUGIB-related procedures, and predictive factors were evaluated. RESULTS: Of 184,885 adult patients admitted with NVUGIB, 1.6% (2990) had COVID-19. Patients with NVUGIB and COVID-19 showed higher inpatient mortality, acute kidney injury, need for intensive care, and resource utilization metrics. Notably, there was a lower rate of early esophagogastroduodenoscopy (EGD). Multivariate logistic regression revealed conditions like peptic ulcer disease, mechanical ventilation, and alcohol abuse as significant positive predictors for NVUGIB in COVID-19 patients, whereas female gender and smoking were negative predictors. CONCLUSION: Our findings suggest that COVID-19 significantly increases the risk of mortality and complications in NVUGIB patients. The observed decrease in early EGD interventions, potentially contributing to higher mortality rates, calls for a review of treatment strategies. Further multicenter, prospective studies are needed to validate these results and improve patient care strategies.

Endoscopic ultrasound (EUS)-guided liver biopsy is gaining popularity for liver parenchymal sampling due to its detailed visualization of liver anatomy, precision in sampling, and the ability to combine liver biopsy with other endoscopic goals. In this study, we present a case involving an anatomically complex, immunocompromised patient who underwent EUS-guided liver biopsy. While the samples were sufficient and progressed the management of her autoimmune hepatitis, her course was complicated by a multiloculated liver abscess. EUS liver biopsy has an excellent safety profile, but a small risk of infection remains, especially in immunocompromised patients or those with preexisting biliary obstruction.
RESUMO
AIMS: A synthetic lifting agent, ORISE, used for endoscopic mucosal resections, has been recalled from the market since November 2022 due to clinical complications. Despite this, the impact of ORISE-associated complications is expected to persist in the foreseeable future. We present a large single institutional series of therapeutic resections from patients for whom ORISE was used for initial endoscopic procedures, highlighting the pitfalls and complications associated with its use. METHODS: All specimens showing lifting agent granulomata (LAGs) associated with the use of ORISE were identified. The H&E slides were reviewed to define the morphological characteristics and extent of LAG in the intestinal wall and other organs. The clinical impression and gross findings were compared with the final pathological diagnosis. RESULTS: 34 cases (28 resections and 6 repeat endoscopic mucosal resection specimens) showed LAG. On microscopy, 20.5% showed no residual disease, 64.7% also showed residual precursor lesion and 14.7% also showed malignancy. In 64.2% of cases, a mass lesion was seen grossly but no malignancy was identified microscopically. ORISE was present in vascular spaces (n=9), lymph nodes (n=2), other organs such as appendix (n=1) and omentum/peritoneum (n=1). The major discordance between clinical impression (mass/neoplasm) and final pathology (no residual malignancy) was seen in 4/34 (11.8%) cases. LAGs were seen up to 10 months after the use of ORISE in the prior endoscopic procedure. CONCLUSION: ORISE deposits may mimic residual/disseminated neoplasm and prompt inadvertent changes in surgical decisions. Awareness of this pitfall is essential to prevent unwarranted surgical resections in patients undergoing follow-up for endoscopically resected lesions.
RESUMO
Video 1The mass was identified at the upper- to mid-esophagus, 25 cm from the central incisors. No varices were seen on further examination of the esophagus. A 4-mm injector force needle was used to create a large submucosal injection using BlueBoost lifting agent proximal to the mass. A longitudinal mucosal incision was then made using the hybrid T-type electrocautery knife, 20 cm from the central incisors.The cutting current was the preset Endocut Q mode, and the coagulation setting was spray coag mode, effect 2 and 40 W.Next, tunnel creation by submucosal dissection was performed with a focus on keeping the submucosal space as clean as possible. Carbon dioxide was used for insufflation to prevent pneumoperitoneum.A smooth-surfaced oval mass was identified originating from the muscularis propria layer. Dissection was extended 2 cm distally beyond the mass. Next, resection of the mass was performed. First, the mucosal surface of the mass was dissected. Dissection began at the distal portion, proceeded to the left and right lateral borders, and then continued toward the proximal portion. The mass was dissected away from the muscularis propria.We focused on freeing the mass, ensuring this esophageal mass was intact throughout dissection. The attached bands of muscularis propria at the distal portion were carefully resected completely.Water irrigation was used at this time to ensure better visualization for resection. The remaining attached bands of muscularis propria were resected, ensuring complete en bloc resection. Afterward, the mass was suctioned into the cap and carefully retrieved as shown, and then sent to pathology for processing.The entire defect bed was inspected post-resection, and no perforation or bleeding was identified.The mucosal defect was completely closed with through-the-scope hemostatic clips in a longitudinal fashion beginning with approximation of the defect at the distal portion.
RESUMO
Background and study aims Noninvasive ampullary neoplasms may be removed by surgery or endoscopy. However, given the morbidity and mortality associated with surgery, endoscopic papillectomy (EP) is the preferred approach. Radiofrequency ablation (RFA) after EP has emerged as a promising alternative therapy to avoid surgery after incomplete EP. Our goal was to evaluate the efficacy and safety of RFA for residual or recurrent lesions with intraductal extension after endoscopic papillectomy. Patients and methods The inclusion criteria include clinical trials, cohort studies, and case series evaluating patients with residual or recurrent lesions with intraductal extension after EP treated with RFA. Case reports, duplicated data, and studies with follow-up periods < 10 months were excluded. The metanalysis evaluated adverse events, surgical conversion rate, clinical success and recurrence. Results Seven studies were selected, totaling 124 patients. RFA was associated with a clinical success rate of 75.7% (95% confidence interval [CI] 65.0-88.0%; I 2 = 23.484) in a mean follow-up period < 10 months. However, the biliary stricture rate was 22.2% (95% CI 12.1-28.4%; I 2 = 61.030), 14.3% of pancreatitis (95% CI 8.8-22.3%; I 2 < 0.001), 7.0% of cholangitis (95% CI 3.3-14.5%; I 2 < 0.001), 4.0% of bleeding (95% CI 1.7-9.3%; I 2 < 0.001), and recurrence of 24.3% (95% CI 16.0-35.0%; I 2 = 23.484). Conclusions RFA is feasible and appears to be effective for managing residual or recurrent lesions with intraductal extension after EP. However, long-term follow-up and high-quality studies are required to confirm our findings.
RESUMO
Pyloric gland adenomas (PGAs) are rare neoplasms found not only in the gastrointestinal tract but also in other extragastrointestinal organs. They have potential for malignant conversion, and early detection and removal is imperative to prevent invasive disease. PGAs prove difficult in management and surveillance given their rarity. However, increasing familiarity with histological appearance and use of advanced tools such as echoendosonography can bring greater understanding of their clinical history. We describe a unique case of a PGA detected within a hiatal hernia sac characterized with echoendosonography and highlight the need to develop surveillance protocols for these types of lesions.
RESUMO
Kaposi sarcoma (KS) is a pathological endothelial growth associated with human herpes virus-8 which primarily affects the skin. In HIV-negative men who have sex with men, the clinical presentation of KS resembles the classic form limited to cutaneous or multifocal disease. In this report, we present a unique case of a healthy 61-year-old man who has sex with men with an isolated gastrointestinal KS who does not meet criteria for any of the typical KS clinical variants. Proper follow-up and regular HIV screenings are needed to evaluate the potential progression course of the disease in these patients.
