RESUMEN

Portal cavernoma is a major cause of extrahepatic portal hypertension (EHPH) in children. It is a serious condition, due to the frequency and severity of digestive hemorrhages secondary to the rupture of esophageal varices (EV). Neonatal umbilical catheterization is a significant risk factor for the development of portal vein thrombosis (PVT) and portal hypertension. We report a case of a five-year-old male who presented with upper gastrointestinal (GI) bleeding on ruptured esophageal varices resulting from a portal cavernoma, complicating neonatal umbilical vein catheterization. This case illustrates the risk of severe vascular complications, particularly portal hypertension that can result from neonatal umbilical vein catheterization.

RESUMEN

Cholecystoduodenal fistula (CDF) is an uncommon condition characterized by an abnormal connection between the gallbladder and the duodenum, often linked to cholelithiasis. It typically presents with nonspecific symptoms such as abdominal pain and jaundice but can occasionally result in severe upper gastrointestinal (GI) bleeding. This report describes the case of a 94-year-old female who presented with hypovolemic shock and multiple episodes of hematemesis. An upper GI endoscopy confirmed a CDF with active hemorrhage. Due to her comorbidities and poor performance status, an endoscopic approach using hemostatic spray was chosen, resulting in a favorable clinical outcome. The development of CDF is typically a result of chronic gallbladder inflammation and cholecystitis, leading to adhesion and erosion into the duodenum. Diagnosis involves imaging and endoscopic techniques, and management varies based on the patient's condition, encompassing surgical, endoscopic, or conservative approaches. This case highlights the necessity of considering CDF in the differential diagnosis of upper GI bleeding, especially in patients with recurrent cholecystitis, and emphasizes the importance of individualized management strategies. It is notable for the use of a minimally invasive endoscopic technique to manage a high-risk patient, highlighting an alternative to surgical intervention.

RESUMEN

Upper gastrointestinal bleeding (UGIB) is a significant concern in children, contributing to 6-20% of cases in pediatric intensive care units. This study evaluates the roles of Helicobacter pylori (H. pylori) infection and non-steroidal anti-inflammatory drug (NSAID) usage in the etiology of UGIB in children, with a particular focus on trends observed during the COVID-19 pandemic. We conducted a retrospective analysis of 103 pediatric patients who underwent esophagogastroduodenoscopy (EGD) for UGIB between January 2015 and December 2023. Of these, 88 patients were included in the final analysis, where the source of bleeding was successfully identified. Hematemesis was the most common presentation, and the source of bleeding was identified in 85.43% of cases. The prevalence of H. pylori infection remained stable across the pre-pandemic (39.7%) and post-pandemic (36.7%) periods. However, NSAID usage increased nearly threefold during the pandemic, with 36.7% of post-pandemic UGIB cases associated with NSAID use, compared to 12.1% pre-pandemic. These findings underscore the significant roles of H. pylori and NSAID use in pediatric UGIB, with a notable increase in NSAID-related cases during the pandemic.

RESUMEN

Splenic venous hypertension or left-sided portal hypertension is a rare condition caused by an obstruction of the splenic vein. Usually, it presents with upper gastrointestinal bleeding in the absence of liver disease. Etiologies can be classified based on the mechanism of development of splenic vein hypertension: compression, stenosis, inflammation, thrombosis, and surgically decreased splenic venous flow. Diagnosis is established by various imaging modalities and should be suspected in patients with gastric varices in the absence of esophageal varices, splenomegaly, or cirrhosis. The management and prognosis vary depending on the underlying etiology but generally involve reducing splenic venous pressure. The aim of this review was to summarize the etiologies of splenic venous hypertension according to the mechanism of development.

RESUMEN

BACKGROUND: Meta-analysis of 10 randomized prospective trials demonstrated a higher risk of postoperative bleeding from pancreaticogastrostomy (PG) compared with pancreatojejunostomy following pancreatoduodenectomy (PD). This study evaluated the incidence, risk factors, and treatment of anastomotic bleeding from invaginated PG. METHODS: We retrospectively evaluated all consecutive PDs performed between April 1, 2011 and December 31, 2022 using invaginated PG by the double purse-string technique. Multivariate analysis identified risk factors for anastomotic PG bleeding. RESULTS: During the study, 695 consecutive patients with a median age of 66 years underwent PD; the majority was performed for ductal pancreatic adenocarcinomas. Simultaneous vascular resections were performed in 328 patients. Postoperative mortality was 4.1%. Bleeding from PG occurred in 33(4.6%) patients at a median interval of 5 days (range, 1-14) from surgery, leading to reoperation in 21(63%). PG bleeding-related mortality was 9.0%. Multivariate analyses identified a soft pancreatic texture and Wirsung duct > 3 or ≤ 3 mm (Class C and D, respectively, of the ISGPS) (odds ratio [OR]: 2.17, 95% confidence interval [95% CI]: 1.38-3.44; P = 0.0009) and wrapping of the invaginated pancreas (OR: 0.37, 95% CI: 0.17-0.84; P = 0.01) as independent risk factors for PG bleeding. CONCLUSIONS: In a large volume setting, anastomotic bleeding from invaginated PG occurred in ~ 5% of patients and was associated with soft pancreatic parenchyma and small wirsung duct. The reduced rate of PG bleeding observed with wrapping of the invaginated pancreatic stump warrants further evaluation in a prospective randomized study.

RESUMEN

Acute esophageal necrosis is a rare syndrome with endoscopic findings of a diffuse circumferential pattern of black mucosa. Although underlying pathogenesis is unclear, it is known to have associations with malignancy. We present a rare case of a patient with a history of metastatic urothelial carcinoma who was found to have acute esophageal necrosis.

RESUMEN

A Dieulafoy lesion is an abnormal artery located in the gastric submucosa that represents a rare cause of upper gastrointestinal bleeding. These lesions typically present as massive hemorrhages in older patients, with multiple medical comorbidities. The lesions are diagnosed with endoscopy and treated with hemostasis by clip placement or coagulation. This case report is that of a rare presentation of this rare condition in a younger 18-year-old patient with no medical comorbidities. He presented with hematemesis, melena, and syncope in the setting of ibuprofen self-treatment for a recent upper viral illness. This medication use is a proposed inciting factor for the bleeding lesion, though he had a history of a splenic artery embolization following a remote motor vehicle accident, which could represent a mechanism for a rare acquired lesion. A gastroenterologist was consulted and assisted in the diagnosis and management of this patient. His lesion was identified and treated within 24 hours of his presentation.

RESUMEN

BACKGROUND AND AIMS: Gastrointestinal bleeding is a major healthcare burden and is associated with significant morbidity and mortality. This study aimed to assess the prevalence, clinical presentation, and risk factors of patients presenting with gastrointestinal bleeding in the emergency department. MATERIALS AND METHODS: This retrospective study was conducted in two tertiary care hospitals in Riyadh, Saudi Arabia. The medical records of patients who presented to the emergency department with gastrointestinal bleeding between January 2010 and January 2020 were reviewed. Patients aged 18 years or older, with gastrointestinal bleeding (upper or lower) regardless of underlying cause, lifestyle, location of bleeding, health status, or medication use, were included. Demographic characteristics, initial vital signs, medical history, physical examination findings, comorbidities, medications, laboratory and radiological investigations, cause and stage of liver disease, management, and complications were recorded. Endoscopic findings and management of the bleeding site were collected according to the presenting symptoms. RESULTS: A total of 760 patients were included. The mean age was 62.7 ± 17.8 years, and 61.4% were males. The most common comorbidities at presentation were hypertension (54.1%), diabetes mellitus (51.2%), and ischemic heart disease (18.2%). The origins of the bleeding were lower gastrointestinal in 52% and upper gastrointestinal in 48% of patients. CONCLUSIONS: Lower gastrointestinal bleeding was found to be more common than upper gastrointestinal bleeding. Hemorrhoids, polyps, diverticular disease, and colonic ulcers were the major risk factors for lower gastrointestinal bleeding. In contrast, upper gastrointestinal bleeding was predominantly caused by esophageal varices, gastritis, and peptic ulcers.

RESUMEN

Esophageal varices commonly affect cirrhotic patients as a result of elevated portal system resistance. Blood pools within esophageal portosystemic collateral vessels, which can eventually rupture, leading to life-threatening hemorrhage. To prevent this, cirrhotic patients without a history of varices undergo endoscopic surveillance for varices every 2-3 years. We present an unusual case of variceal hemorrhage in a patient who was seen to have no varices on endoscopic evaluation only a month earlier.

RESUMEN

This case report describes an 80-year-old female patient admitted to the emergency department due to abdominal distension, abdominal pain, and hematemesis persisting for three days. Subsequent postoperative pathological examination confirmed the diagnosis of peritoneal cancer. The occurrence, diagnosis, treatment, and prognosis of primary peritoneal cancer (PPC) are presented in detail. PPC is a type of cancer originating from the primary peritoneal mesothelium organization, causing diffuse malignant tumors in the abdominal and pelvic regions. Due to the lack of specific clinical manifestations for this disease, the importance of early diagnosis and treatment is hereby emphasized. The article also mentions the histological source of this type of cancer and the advantages of preoperative intraperitoneal chemotherapy in improving the efficacy of PPC treatment. Finally, the importance of a comprehensive treatment approach and proficient use of targeted therapy techniques are highlighted to enhance the treatment outcomes of PPC.

RESUMEN

BACKGROUND: Gastric teratoma is an extremely rare tumor, representing <1% of all pediatric teratomas, and commonly manifests as a palpable abdominal mass. Upper gastrointestinal tract bleeding in newborns and infants is rare and is mostly caused by a benign lesion. CASE REPORT: We present a 3-month-old boy who presented with recurrent attacks of hematemesis, vomiting, and melena which on work up revealed a gastric teratoma. DISCUSSION/CONCLUSION: Owing to the unique characteristics and the extreme rarity of this entity, accurate preoperative diagnosis has remained elusive.

RESUMEN

Key Clinical Message: Duodenal GISTs are rare and challenging tumors. Acute life-threatening upper GI bleeding is a possible presentation of duodenal GISTs. Surgery is the standard treatment for localized duodenal GISTs. Imatinib is an effective adjuvant therapy for duodenal GISTs. Abstract: GIST is the most common mesenchymal neoplasm of the gastrointestinal tract, accounting for 1%-2% of gastrointestinal tumors. They originate from the interstitial cells of Cajal and are rare in patients younger than 30 years. The stomach is the most common site, followed by the small intestine and colon. GISTs are caused by a gain-of-function mutation in the proto-oncogene receptor tyrosine kinase, with activating mutations in KIT being the most common. Most GISTs are asymptomatic. Even if gastrointestinal bleeding is the most common complication life-threatening hemorrhage is extremely uncommon. We present a case of a 31-year-old male patient presented with massive active hematemesis and melena with hemorrhagic shock. The patient presented with massive hematemesis and melena of 1 h duration. Endoscopy showed pulsating active bleeding from the third part of the duodenum which was difficult to manage via endoscopy. Histopathologic evaluation showed spindle cell type GIST. Intraoperatively, there was a nodular mass with active bleeding on the third part of the duodenum. Duodenectomy with end-to-end anastomosis was done. Discharged with no postoperative complication and was put on imatinib. There are considerable challenges that arise in the diagnosis and treatment of duodenal gastrointestinal stromal tumors (GISTs) when they present with life-threatening upper gastrointestinal hemorrhage. In order to achieve the best possible outcomes for patients, it is crucial to have a comprehensive understanding of the clinical presentation, diagnostic methods, and treatment approaches.

RESUMEN

Duodenocaval fistula is an extremely rare and life-threatening cause of gastrointestinal hemorrhage and septicemia. Diagnosing this condition is challenging due to its nonspecific symptoms, leading to significant delays in diagnosis and contributing to its remarkably high mortality rate. We present a unique case of duodenocaval fistula associated with prior radiation, peptic ulcer disease, and antiangiogenic cancer therapy, nearly resulting in the death of a young patient.

RESUMEN

Aortoesophageal fistula is rare and typically presents itself to the emergency department as Chiari's Triad of mid-thoracic pain, sentinel arterial hemorrhage, and exsanguination after a symptom-free interval. However, fatal bleeding may be the first and last presentation of an aortoesophageal fistula. When a patient experiences massive hematemesis without witnesses, EMS may assume that bleed is of a traumatic mechanism. We present a case of a 59-year-old male with no previous medical history who was transported to a trauma center unconscious and with massive bleeding of unknown origin. Computed tomography revealed a thoracic aortic aneurysm and an aortoesophageal fistula. Bleeding was not controlled and the patient expired. Trauma bay personnel should follow an algorithm which includes a prompt tamponade of the bleed using a Sengstaken-Blakemore tube or esophageal balloon paralleled by massive transfusion and obtaining an early computed tomography scan to manage patients with massive gastroesophageal bleeding until appropriate surgical interventions can be initiated.

RESUMEN

Severe thrombocytopenia induced by anti-tubercular therapy (ATT) is a rare but potentially life-threatening complication. Severe thrombocytopenia is a known adverse effect of ATT, but its association with fatal hemoptysis is rare. Hematemesis and hemoptysis are two serious symptoms that indicate bleeding from the upper gastrointestinal and the lower respiratory tract, respectively. We report a rare case of a 65-year-old man, a diagnosed case of tuberculosis on ATT, who presented with massive hemoptysis. On navigating the bleed, the source was found to be a vocal cord bleed, which further led to massive clot formation in the left bronchus, leading to the collapse of the subsequent lung, leading to mortality. This case emphasizes the importance of recognizing ATT as a potential cause of bleeding and considering causes of massive hematemesis that are not gastrointestinal. It also highlights the need for a thorough evaluation of the airway in such patients.

RESUMEN

INTRODUCTION AND IMPORTANCE: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors with varied clinical presentations. This case report highlights the significance of recognizing atypical GIST presentations, such as hematemesis, especially in resource-limited settings. CASE PRESENTATION: A 52-year-old male from an economically disadvantaged background presented with hematemesis and severe anemia. Initial investigations suggested iron deficiency anemia, but further evaluation revealed a gastric mass, raising suspicion of GIST. Despite limited resources, a distal radical gastrectomy confirmed the GIST diagnosis, and the patient underwent surgical resection followed by imatinib therapy. CLINICAL DISCUSSION: This case underscores the diagnostic challenges posed by GISTs and the importance of imaging studies, given their often nonspecific symptoms. Limited resources and economic constraints in low-income settings can hinder comprehensive diagnosis and treatment. Access to specialized oncological services is crucial for accurate management. CONCLUSION: Early recognition and management of GIST, even in atypical presentations like hematemesis, can significantly impact patient outcomes. This case report highlights the need for improved healthcare infrastructure in low-resource settings and calls for initiatives to ensure equitable access to diagnostic tests and appropriate treatment for rare diseases like GIST.

RESUMEN

This is the case of a 52-year-old Indian lady who presented with hematemesis, severe anemia, and an abdominal lump in cardiac failure. On radiographic evaluation, the lesion appeared to be gross circumferential asymmetric proximal gastric wall thickening, with suspicion of gastric lymphoma or tubercular hypertrophic gastritis. After stabilization with multiple transfusions, she underwent proximal D2 gastrectomy with esophago-gastric anastomosis and a total splenectomy. Grossly, the gastric rugae appeared to be hypertrophied and firm. No growth was identified grossly; however, necrotic areas were identified at the distal end. Microscopic examination of multiple sections studied showed significant foveolar hyperplasia, tortuous glands, and a few cystically dilated foveolar glands, which were limited up to the muscle layer. Mild serosal congestion was seen. No atypia or invasion was seen. An impression to consider is the possibility of Ménétrier's disease (MD). MD is an acquired protein-losing enteropathy with giant gastric rugal folds, decreased acid secretion, and increased gastric mucous production. Radiographically, endoscopically, and grossly, the condition can be confused with malignant lymphoma or carcinoma. It is difficult to diagnose, and histopathological confirmation of the resected specimen is needed for a definitive diagnosis. Our intention in presenting this case is to emphasize that MD can present as massive hematemesis and should be considered in a differential diagnosis. Surgical treatment by total or partial gastrectomy is recommended for cases with persistent, debilitating symptoms or a risk of cancer.

RESUMEN

Metastatic gastrointestinal neuroendocrine tumors classically appear as contrast-enhancing lesions on computed tomography. However, in a small percentage of patients, these lesions can be cystic in nature, leading to false diagnoses of benign or infectious lesions such as echinococcosis. Hence, every cystic lesion of the liver must be carefully investigated before making the treatment plan. We report a patient with hematemesis caused by a large gastric ulcer with multiple cystic lesions in the left lobe of the liver abutting the stomach. The liver lesions were misdiagnosed as hepatic echinococcosis, and the patient was started on medical therapy. However, when medical therapy failed, the patient underwent surgical excision and the histopathology showed cystic metastases of a gastric neuroendocrine tumor.

RESUMEN

Acute esophageal necrosis (AEN) also known as necrotizing esophagitis or black esophagus is an extremely rare cause of upper gastrointestinal (GI) bleeding. This condition is considerably rare, and the exact pathophysiology of the development of AEN is still unclear. There is consensus that it is caused by a combination of esophageal mucosal injury due to gastric acid and ischemic injury due to vascular compromise. The management of AEN includes correcting the multitude of underlying predisposing conditions as well as agile symptomatic management and close monitoring for signs of hemodynamic compromise. We here present an interesting case of a middle-aged male patient who presented with hematemesis and underwent emergent esophagogastroduodenoscopy (EGD), which revealed severe necrotic esophagus. We also discussed the risk factors, pathophysiology, and management of AEN.

RESUMEN

OBJECTIVE: To describe the medical management and outcome of a dog suffering severe hydrogen peroxide toxicity. CASE SUMMARY: A 3-year-old neutered female Bichon Frise was presented to an emergency and referral practice after ingestion of 10-20 mL/kg 3% hydrogen peroxide. On presentation, the dog was obtunded, was tachypneic, and had severe gastric tympany. Abdominal radiographs revealed pneumoperitoneum, gastric pneumatosis, and hepatic venous gas. The dog was managed conservatively with supportive care and oxygen therapy. Repeat radiographs 6 hours later showed complete resolution of all gas inclusions. While hospitalized, the dog developed severe hematemesis, and abdominal ultrasound revealed severe gastric wall thickening. Subsequent endoscopy confirmed severe gastric mucosal necrosis without evidence of deeper ulceration and relatively mild petechiation of the esophagus. The dog was ultimately discharged after 5 days of hospitalization and continued to do well at home. Recheck ultrasound 5 weeks postdischarge showed normal gastric wall appearance. NEW OR UNIQUE INFORMATION PROVIDED: To the authors' knowledge, this is the first reported case of pneumoperitoneum secondary to hydrogen peroxide toxicity and the first description of the clinical course of severe toxicity in dogs.
