RESUMO
Upper gastrointestinal bleeding (UGIB) is a major cause of morbidity and mortality. Clinical symptoms that patients may present with include: hematemesis, coffee-ground emesis, melena, and hematochezia. Clinical signs can range from tachycardia to shock. The anatomical landmark that differentiates upper gastrointestinal (GI) bleeds from lower bleeds is the ligament of Treitz. The first steps of treating a patient who presents with signs of UGIB are resuscitation with appropriate fluids and blood products as necessary. The consideration of endoscopy and the urgency at which it should be performed is also vital during initial resuscitation. Endoscopic therapy should ideally be performed within 24 hours of presentation after initial stabilization with crystalloids and blood products. Intravenous proton pump inhibitors are the mainstay in the initial management of upper GI bleeding from a non-variceal etiology, and they should be administered in the acute setting to decrease the probability of high-risk stigmata seen during endoscopy. Pro-kinetic agents can be given 30 minutes to an hour before endoscopy and may aid in the diagnosis of UGIB. There are 3 broad categories of endoscopic management for UGIB: injection, thermal, and mechanical. Each endoscopic method can be used alone or in combination with others; however, the injection technique with epinephrine should always be used in conjunction with another method to increase the success of achieving hemostasis. In this review article, we will review the steps of triage and initial resuscitation in UGIB, causes of UGIB and their respective management, several endoscopic techniques and their effectiveness, and prognosis with a primary focus limited to non-variceal bleeding.

BACKGROUND AND STUDY AIMS: Endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) has been well utilized in treating malignant gastric outlet obstructions (GOO) given its efficacy and lower risk profile compared to surgery. However, its efficacy and potential for use in patients with benign GOO who are poor surgical candidates is not well documented. The aim of this study was to examine the role of EUS-GJ in treatment of benign GOO in select patients. PATIENTS AND METHODS: This is a single-center, open-label, retrospective descriptive study that included all consecutive patients undergoing EUS-GJ to treat benign causes of GOO. Direct antegrade and direct retrograde methods were utilized. RESULTS: A total of 18 patients were included, 38.9% female with an average age of 63.3 years. Extrinsic GOO was present in (10 of 18) 55.5% of patients and intrinsic etiology was present in (8 of 18) 45.5% of patients. Technical success was achieved in 100% (18 of 18) patients and clinical success was achieved in 94% (17 of 18) patients. In total, 13 patients had follow-up endoscopy, 2 patients were treated relatively recently in time, 1 patient was lost to follow-up, and 2 patients died of other chronic illnesses. Stents remained in place for a median of 286 days (range 88-1444 days). In patients whose stents were removed, 75% (3 of 4) had extrinsic etiologies of GOO. CONCLUSIONS: This study reports a favorable long-term patency with excellent technical and clinical success of EUS-GJ in patients with benign GOO. Despite the limitations of sample size and retrospective nature, it adds to the extremely limited literature of EUS-GJ in management of patients with benign GOO.

Pancreatitis is a condition much more commonly found in adults, but when diagnosed in the pediatric population, is often due to medications, congenital pathology, and critical illness. This patient had previously undergone treatment with 6-mercaptopurine and presented with pancreatitis that eventually worsened to a walled-off necrotic collection with paracolic extensions reaching the pelvis. Given clinical worsening with development of shock, procedural options for source control were weighed with gastroenterology, pediatric surgery, and interventional radiology, before pancreatic necrosectomy was determined to be the treatment of choice, given the adjacency of the collection to the stomach. A total of three separate endoscopic pancreatic necrosectomy procedures were performed and the patient s clinical status improved greatly, with vast improvement later seen on outpatient imaging. This successful treatment course argues for the efficacy of pancreatic necrosectomy even in very large walled off collections, and most importantly, lead to a positive outcome in this young patient.

Penetrating peptic ulcers often lead to severe complications. The development of uretero-enteric fistulas is rare and can be challenging to diagnose and treat. Here, we present the case of a 41-year-old patient who previously underwent gastrojejunostomy for superior mesenteric artery syndrome and developed a peptic jejunal ulcer, leading to a uretero-jejunal fistula and finally causing acute pyelonephritis. The patient was managed with a multidisciplinary approach including medical therapy and endoscopic and radiologic interventions.
RESUMO
BACKGROUND AND AIMS: Distinguishing Crohn's disease (CD) from ulcerative colitis (UC) may be difficult when the disease is limited to the colon. Transmural healing is an important adjunctive measure of inflammatory bowel disease activity. The aim of this study was to examine the role of EUS in differentiating CD versus UC and evaluating transmural disease activity. METHODS: This prospective cohort study enrolled 20 patients with CD (10 active [aCD], 10 inactive), 20 patients with UC (10 active [aUC], 10 inactive), and 20 control subjects who underwent colonoscopy from 2019 to 2021 at a tertiary care center. Measurements of bowel wall layer thickness from the rectum and cecum were obtained using a through-the-scope US catheter (UM-3R-3; Olympus, Center Valley, Penn, USA) at the time of colonoscopy. RESULTS: Compared with control subjects, patients with aCD had thicker rectal submucosa and total wall layer (submucosa median, 1.80 mm [interquartile range {IQR}, 1.40-2.00] vs .60 mm [IQR, .40-.70]; total wall median, 3.70 mm [IQR, 3.52-4.62] vs 2.10 mm [IQR, 1.70-2.40], respectively; P < .01). Similar significant findings were observed for the cecal wall layers. Compared with control subjects, patients with aUC had thicker rectal mucosa and total wall but not submucosa or muscularis propria layers (mucosa median, 1.35 mm [IQR, 1.12-1.47] vs .60 mm [IQR, .57-.70]; total wall median, 3.45 mm [IQR, 2.85-3.75] vs 2.10 mm [IQR, 1.70-2.40], respectively; P < .01). Patients with aCD compared with those with aUC had a significantly thicker rectal submucosa layer (median, 1.80 mm [IQR, 1.40-2.00] vs .55 mm [IQR, .40-.75], respectively, P < .01). Cutoff values of 1.1 mm for rectal submucosa in CD (sensitivity, 1.0; specificity, 1.0) and 1.1 mm for rectal mucosa in UC (sensitivity, .8; specificity, .9) were found to differentiate active from inactive disease. CONCLUSIONS: EUS measurements of colon wall layers can help diagnose aCD versus aUC and assess transmural disease activity. (Clinical trial registration number: NCT03863886.).

BACKGROUND: It was reported that about 60% of the physicians in the USA believed that their Gastroenterology fellowship poorly prepared them for large polyp resection. The aim of this study was to compare endoscopic mucosal resection (EMR) efficacy and complication rates between skilled general gastroenterologists who perform high volume of EMR and advanced endoscopists. METHODS: We identified 140 patients with documented large colonic polyps treated by 4 providers using EMR technique at Carilion Clinic, in Roanoke, Virginia, USA between 01/01/2014-12/31/2017, with follow-up through 10-2018. Information on demographics, clinical and pathological features of high-risk polyps (i.e., size, histology, site, and degree of dysplasia), timing of surveillance endoscopies, tools used during resection, and skills of performing endoscopist's were extracted. The cumulative risks of polyp recurrence after first resection using EMR technique were estimated using Kaplan-Meier curves. RESULTS: One hundred and forty patients were identified (mean age, 64.1±11.2 years; 47.1% males). Fifty-five polyps (39.3%) were removed by 2 skilled gastroenterologists and 85 (60.7%) were removed by advanced endoscopists. Most of the polyps resected were located in the right colon (63.6%) and roughly half of the polyps were removed in piecemeal fashion. At follow-up endoscopy, the advanced endoscopy group had lower polyp recurrence rates. The median recurrence after polypectomy was significantly different between the groups (0.88 and 1.03 years for skilled gastroenterologists who did not complete and completed EMR hands-on workshops; respectively vs. 3.99 years for the advanced endoscopist who did not complete EMR hands-on workshop, P=0.03). CONCLUSIONS: There is a need for additional EMR training since polyp recurrence was significantly different between the groups despite high rates of piecemeal resection in the advanced endoscopy groups.

Although breast cancer is the most common form of cancer in women, metastasis to the stomach is incredibly rare. Gastric metastasis of breast cancer has been described in the literature, with an estimated median of 6 years from the initial diagnosis of primary breast cancer to metastasis and multiple instances greater than 10 years. In this case, a patient presented with gastric outlet obstruction in the setting of breast cancer metastasis to the pylorus 25 years after the original diagnosis.
RESUMO
Objective Underwater endoscopic mucosal resection (UEMR) is reported to be superior to conventional endoscopic mucosal resection (CMER) for the complete resection of large polyps and may offer increased procedural efficiency. Aims To compare recurrence rates and adverse events between UEMR and CEMR and define risk factors related to recurrence. Also, to assess recurrence rates in piecemeal endoscopic mucosal resection (EMR) based on the number of pieces resected. Methods We identified all patients with large polyps treated using the UEMR technique at Carilion Clinic, Roanoke, VA, USA between January 1, 2014 and December 31, 2017 with follow-up through October of 2018. We matched the UEMR patients with patients treated using the CEMR technique (1:2 matching, respectively). The Kaplan-Meier curve was used to estimate the cumulative risks of polyp recurrence. The Cox proportional hazard analysis was used to assess risk factors for developing polyp recurrence. Results Sixty-eight patients (mean age: 63.4 ± 12.5 years; 52.9% males) with polyps removed using the UEMR technique (Group 1) were matched with 122 patients (mean age: 64.4 ± 10.0 years; 51.6% males) who had polyps removed using CEMR (Group 2). Polyps resected in fewer pieces (≤ 3) had lower recurrence rates compared to the ones resected in >3 pieces. Right colon polyps removed using UEMR had a lower recurrence rate compared to right colon polyps resected using CEMR. Polyp size and a high degree of dysplasia were associated with a high risk of polyp recurrence after resection. Completing advanced endoscopy training was also associated with a lower risk of recurrence. Conclusion UEMR had a lower recurrence rate compared with CEMR for right colon polyps. Factors associated with recurrence included the degree of training, high-grade dysplasia, and polyp size.
RESUMO
Background and study aims The etiology of idiopathic acute pancreatitis (IAP) should always be defined. Our aim was to compare the diagnostic value of endoscopic ultrasound (EUS) versus secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) in patients with IAP. Patients and Methods Patients admitted to a single tertiary care University hospital with IAP were invited to participate in the study. Enrolled patients underwent EUS and S-MRCP in a single-blinded comparative study. EUS and S-MRCP were performed no sooner than 4 weeks after discharge. The diagnostic yield of EUS and S-MRCP and demographic variables were included in the analysis. Additional follow-up, results of subsequent serology, radiographic exams, and relevant histological analysis were considered in determination of the final diagnosis. Results A total of 34 patients were enrolled; EUS was normal in six, cholelithiasis was defined in 15, choledocholithiasis in two, pancreas divisum in three, branch-type intraductal papillary mucinous tumor (IPMT) in three, and chronic pancreatitis in five. S-MRCP identified choledocholithiasis in one, divisum in four, branch-type IPMT in three, chronic pancreatitis in two; 24 subjects diagnosed as normal by S-MRCP. Diagnostic correlation between EUS and S-MRCP was slight (kappaâ=â0.236, 95â% confidence interval: 0.055-0.416). EUS provided a statistically significantly higher diagnostic yield than S-MRCP: 79.4â% (CI95â%: 65â%-94â%) vs 29.4â% (CI95â%: 13â%-46â%) (Pâ=â0.0002). The sensitivity, specificity, and positive and negative predictive values of EUS and S-MRCP were 90â%, 80â%, 96â%, 57â% and 33â%, 100â%, 100â% and 16â%, respectively. Conclusion The diagnostic yield of EUS is higher than S-MRCP in patients with IAP.
RESUMO
Background and study aim Malignant bowel obstruction can cause significantly distressing symptoms in patients with end stage cancers, often requiring invasive surgical intervention. With such procedures, risks often outweigh the benefit. We report a novel application of the AXIOS stent and electrocautery-enhanced delivery system to create an enterocolostomy to bypass a small bowel obstruction in the setting of recurrent malignant bowel obstruction. A 72-year-old patient presented with recurrent malignant bowel obstruction and was deemed unfit for surgery. Endoscopic ultrasound was used to deploy an AXIOS stent, creating an enterocolostomy resolving the obstruction.
RESUMO
Background and study aims The aim of the current study was to review the outcomes of a large-scale international registry on endoscopic ultrasound-guided gallbladder drainage (EGBD) that encompasses different stent systems in patients who are at high-risk for cholecystectomy. Patients and methods This was a retrospective international multicenter registry on EGBD created by 13 institutions around the world. Consecutive patients who received EGBD for several indications were included. Outcomes include technical and clinical success, unplanned procedural events (UPE), adverse events (AEs), mortality, recurrent cholecystitis and learning curve of the procedure. Results Between June 2011 and November 2017, 379 patients were recruited to the study. Technical and clinical success were achieved in 95.3â% and 90.8â% of the patients, respectively. The 30-day AE rate was 15.3â% and 30-day mortality was 9.2â%. UPEs were significantly more common in patients with EGBD performed for conversion of cholecystostomy and symptomatic gallstones ( P â<â0.001); and by endoscopists with experience of fewer than 25 procedures ( P â=â0.033). Both presence of clinical failure ( P â=â0.014; RR 8.69 95â%CI [1.56â-â48.47]) and endoscopist experience with fewer than 25 procedures ( P â=â0.002; RR 4.68 95â%CI [1.79â-â12.26]) were significant predictors of 30-day AEs. Presence of 30-day AEs was a significant predictor of mortality ( P â<â0.001; RR 103 95â%CI [11.24â-â944.04]). Conclusion EGBD was associated with high success rates in this large-scale study. EGBD performed for indications other than acute cholecystitis was associated with higher UPEs. The number of cases required to gain competency with the technique by experienced interventional endosonographers was 25 procedures.
RESUMO
Patients with unresectable pancreatic cancer have a poor prognosis. The analysis of prognostic factors before treatment may be helpful in determining the best therapeutic strategies. The aim of the PEACE study is to assess the vascularity of pancreatic malignant tumors using contrast-enhanced harmonic EUS (CEH-EUS) and to clarify the prognostic value of tumor vascularity in patients with locally advanced and metastatic pancreatic cancer. Hereby, we present the protocol of a prospective, nonrandomized, single-arm, multicenter study aiming to assess changes in tumor vascularity using CEH-EUS before and 2 months after treatment initiation in patients with unresectable, locally advanced/metastatic pancreatic cancer and to examine the correlation between vascular changes and treatment response, progression-free survival, and overall survival.
RESUMO
INTRODUCTION: Metastasis to the gallbladder is not common and usually manifests an advanced stage of malignancy. Herein, we report a case of triple negative high grade invasive ductal carcinoma of breast with a metastatic lesion to the gallbladder. CASE PRESENTATION: The patient is a 52-year-old female diagnosed with invasive ductal carcinoma treated with mastectomy and chemotherapy. After 12 months, she presented to the emergency department with right upper quadrant pain and elevated liver chemistries. Abdominal enhanced computed tomography showed periportal and gallbladder wall edema. After cholecystectomy, the resected gallbladder was histologically considered to be a metastatic lesion arising from the primary lung cancer. The second case describes a case of a 77-year-old woman with multiple co-morbidities who presented to the hospital with sepsis secondary to biliary source. Abdominal enhanced computed tomography findings were concerning for acute cholecystitis. After cholecystectomy, the pathology of the resected gallbladder demonstrated cholecystitis and plasmacytoma. CONCLUSION: The atypical presentation of gallbladder metastases could mislead treating providers. The diagnosis might alter management decisions and prognosis.
