Spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma: a rare case.

BACKGROUND: Gastric intramural hematoma is a rare disease. Here we report a case of spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. CASE PRESENTATION: A 75-years-old man was admitted to our department with complaints of abdominal pain. He underwent a whole abdominal computed tomography (CT) scan in the emergency department, which showed extensive thickening of the gastric wall in the gastric body and sinus region with enlarged surrounding lymph nodes, localized thickening of the intestinal wall in the transverse colon, localized indistinct demarcation between the stomach and transverse colon, and a small amount of fluid accumulation in the abdominal cavity. Immediately afterwards, he was admitted to our department, and then we arranged a computed tomography with intravenously administered contrast agent showed a spontaneous isolated gastric intramural hematoma combined with spontaneous superior mesenteric artery intermural hematoma. Therefore, we treated him with anticoagulation and conservative observation. During his stay in the hospital, he was given low-molecular heparin by subcutaneous injection for anticoagulation therapy, and after discharge, he was given oral anticoagulation therapy with rivaroxaban. At the follow-up of more than 4 months, most of the intramural hematoma was absorbed and became significantly smaller, and the intermural hematoma of the superior mesenteric artery was basically absorbed, which also confirmed that the intramural mass was an intramural hematoma. CONCLUSION: A gastric intramural hematoma should be considered, when an intra-abdominal mass was found to be attached to the gastric wall. Proper recognition of gastric intramural hematoma can reduce the misdiagnosis rate of confusion with gastric cancer.

Role of Endoscopy in the Diagnosis, Grading, and Treatment of Portal Hypertensive Gastropathy and Gastric Antral Vascular Ectasia.

Portal hypertensive gastropathy (PHG) and gastric antral vascular ectasia (GAVE) are 2 distinct gastric vascular abnormalities that may present with acute or chronic blood loss. PHG requires the presence of portal hypertension and is typically associated with chronic liver disease, whereas there is controversy about the association of GAVE with chronic liver disease and/or portal hypertension. Distinguishing between GAVE and PHG is crucial because their treatment strategies differ. This review highlights characteristic endoscopic appearances and the clinical features of PHG and GAVE, which, in turn, aid in their appropriate management.

Robotic surgery in the management of synchronous esophageal and gastric perforation after endoscopic dilation.

Upper gastrointestinal perforation is a feared complication of diagnostic and therapeutic endoscopy, with an incidence of perforation between 0.3% and 5%. Even though is rare, the mortality rate can be as high as 40%. Currently, there is no consensus on the best therapeutic strategy and it usually depends on patient stability, the extent of perforation, time to diagnosis, surgeon experience and available resourcesWe present a case of a patient who presented to our institution to undergo an ambulatory oesophageal dilation. After dilation, the patient developed two full-thickness gastric perforations and a full-thickness oesophageal perforation without haemodynamic instability. All perforations were diagnosed and treated with a combination of intraoperative endoscopy and robotic surgery with excellent outcomes.We demonstrate that a robotic approach combined with intraoperative diagnostic endoscopy is a safe and feasible treatment option for esophageal and gastric perforations in a stable patient without large extraluminal contamination.

Natural history of symptoms and prognostic information of the rapid drink challenge and solid bolus swallows in esophagogastric junction outflow obstruction defined by manometry.

BACKGROUND/INTRODUCTION: Esophagogastric junction outflow obstruction (EGJOO) is a condition characterized by poor relaxation of the lower esophageal sphincter (LES), which can manifest as dysphagia and chest pain. The best treatment of EGJOO is unknown as some patients improve without any specific therapy, whereas some patients undergo invasive therapy. Currently, prognostic factors are lacking. We aimed to assess the long-term prognosis and predictors of dysphagia and chest pain by the rapid drink challenge and solid bolus swallows in EGJOO. METHODS: We retrospectively assessed high-resolution esophageal manometries (HRM) performed at our center between 2015 and 2018. The patients completed a dysphagia and chest pain questionnaire a median of 34 months after the HRM/baseline assessment, including the Impaction dysphagia questionnaire-10 (IDQ-10) complemented with questions regarding chest pain and esophageal treatments. Symptoms were compared with HRM findings. RESULTS: In all, 980 HRMs were analyzed and 66 (6.5%) were identified as having HRM findings compatible with EGJOO. Of these, 27 patients with EGJOO (41%) completed the follow-up questionnaires and had no exclusion criteria, and 70% of these patients had dysphagia and 44% chest pain at least once a week. Dysphagia at follow-up was more common in patients with elevated integrated relaxation pressure (IRP) on all three HRM metrics (water swallows, solid bolus swallows, and rapid drink challenge) (p = 0.03, odds ratio: 8.4 (95% CI: 1.2-56.0)), but this was not seen for chest pain (p = 0.45). Abnormal motility patterns on rapid drink challenge or solid bolus swallows were not associated with dysphagia or chest pain at follow-up. CONCLUSIONS: Having a high IRP on three HRM metrics-water swallows, solid bolus swallows, and rapid drink challenge-is associated with a worse prognosis in patients with EGJOO and could potentially be used to select candidates suitable for invasive procedures.

Correlation between Severity of Thrombocytopenia and Portal Hypertensive Gastropathy in Patients with Chronic Liver Disease.

INTRODUCTION: Portal hypertensive gastropathy (PHG) is known but under detected complication of cirrhosis of liver. Patients with stable liver disease are more prone to internal bleeding due to portal hypertension. Thrombocytopenia is a common complication associated with chronic liver disease and it is associated with poor prognosis. The aim of this study is to find out the association between correlation between severity of thrombocytopenia and portal hypertensive gastropathy in patients with chronic liver disease. MATERIALS: This cross-sectional analytical study was conducted in a tertiary care centre at Saveetha Medical College Hospital and Research Centre. A total of 80 consecutive subjects were included in this study. All adult patients admitted with diagnosis chronic liver disease underwent upper GI endoscopy; those with portal hypertensive gastropathy were included in this study. The patient with liver disease with only varices but not gastropathy was excluded. Patient less than 18 years and with poor preparation were excluded from this study. Platelet count was estimated and severity of gastropathy was classified. Correlation of thrombocytopenia and severity of gastropathy was studied. RESULT: Patients with mild portal hypertensive gastropathy category had normal platelet count between 1.5-4.5 lakhs/mm3 . But in patients with severe PHG, almost 80% of patients had thrombocytopenia, in which 8% had severe thrombocytopenia <50,000 cells/mm3 . The inverse relationship between the platelet count and the severity of PHG was statistically significant. CONCLUSION: The severity of thrombocytopenia increased with increasing grade of portal hypertensive gastropathy. Hence platelet count can serve as the prognostic marker of chronic liver disease induced portal hypertensive gastropathy References Chung WJ.

Congenital diaphragmatic hernia with gastric perforation in adult: Intrathoracic gastric perforation.

Congenital diaphragmatic hernias are rarely seen and they are usually diagnosed in the neonatal period. Congenital diaphragmatic de-fect, also known as Bochdalek hernia, usually occurs with the persistence of the pleuroperitoneal canal in the left posterolateral region of the diaphragm in the embryological period. Although it is rarely seen in the adults, conditions such as intestinal volvulus, strangulation, or perforation with congenital diaphragm defect progress with high mortality and morbidity. In this study, we reported our case that we operated for intrathoracic gastric perforation with congenital diaphragmatic defect. When the patient admitted to the hospital, he had an atypical abdominal pain, significant back pain, and suspicious respiratory complaints. Radiological imaging showed that the stomach and the spleen were located in the left hemithorax due to diaphragmatic hernia also stomach was very dilated. Tachycardia, hypotension, and low saturation developed on the 2nd day of the patient's hospitalization. In the control imaging of the patient, in the left hemithorax, stomach was collapsed and the surrounding appearance compatible with hydropneumothorax, after that findings emergency laparotomy was decided. During the operation, as demonstrated by the radiological findings, a diaphragm defect was seen in the left posterolateral region of the diaphragm. The stomach and spleen were herniated to the left hemithorax from this defect. The stomach and spleen were reduced into the abdomen. The left hemithorax was lavaged with 2000 cc isotonic, left tube thoracostomy was applied, and the diaphragm was repaired. The anterior stomach was primarily repaired. In post-operative follow-up, there were no complications other than wound infection and thoracic tube of the patient was removed. The patient who tolerated enteral food was discharged from hospital with full recovery.

Projectile vomiting as presentation of duodenal intramural metastasis from cervical cancer.

OBJECTIVE: To report a case and review literature of bowel metastases from cervical squamous cell carcinoma. CASE REPORT: A 49-year-old woman with a history of FIGO 2013 stage IVB cervical squamous cell carcinoma presented with refractory nausea, projectile vomiting, anorexia, postprandial abdominal pain, and significant weight loss for six months. Restaging images didn't reveal viable tumors but thickened duodenal wall indicating gastric outlet obstruction. Initially, the etiology was masked by chronic erosive duodenitis and mistreated as a duodenal ulcer. After repeated gastrointestinal endoscopic biopsy confirming intramural duodenal metastasis from cervical squamous cell carcinoma, the patient was treated successfully by gastrojejunostomy and adjuvant chemotherapy. She has remained asymptomatic and disease-free for more than 12 months since the surgical metastasectomy. CONCLUSION: Intestine metastasis from cervical cancer is a rare cause that may present as projectile vomiting due to gastric outlet obstruction. Prompt recognition and surgical intervention may provide good outcomes despite the metastatic nature.

Risk factors for portal hypertensive gastropathy.

BACKGROUND: Portal hypertensive gastropathy (PHG) is often underestimated in clinical diagnosis. Gastrointestinal bleeding in cirrhosis of PHG accounts for approximately 10% of upper gastrointestinal bleeding. However, the relationship between PHG and gender, laboratory parameters, liver function and varices is still controversial. In the present study, we aimed to retrospectively evaluate the incidence of PHG and to explore the relationship between PHG and gender, laboratory parameters, liver function and varicose veins. METHODS: A retrospective analysis of 325 patients with cirrhosis who underwent esophagogastroduodenoscopy (EGD) in the Department of Gastroenterology of the Second Hospital of Hebei Medical University from 1 January 2018 to 31 December 2020 was performed. The relationships among age, gender, laboratory parameters, Child-Pugh stage, oesophageal varices (EV), gastric varices (GV) and ascites with PHG were analysed with univariate and multivariate logistic regression. RESULTS: The occurrence of PHG was significantly associated with gender, haemoglobin, platelet count, prothrombin time, albumin, Child-Pugh stage, EV, GV and ascites (P < 0.05). Furthermore, there was a positive correlation between the severity of PHG and the degree of EV, GV and ascites (P < 0.05). Multivariate logistic regression showed that albumin, EV and GV levels were independently associated with the occurrence of PHG. CONCLUSION: The incidence of PHG in cirrhosis was 87.4% in this study. The occurrence of PHG was related to gender, haemoglobin, platelet count, prothrombin time, albumin, Child-Pugh stage, EV, GV and ascites. Albumin, the degree of EV and GV are independent risk factors for the occurrence of PHG.

Changes in the esophagogastric junction outflow obstruction manometric feature based on the Chicago Classification updates.

BACKGROUND: The critical diagnostic criteria for esophagogastric junction outflow obstruction (EGJOO) were published in the latest Chicago Classification version 4.0 (CCv4.0). In addition to the previous criterion [elevated integrated relaxation pressure (IRP) in supine position], manometric diagnosis of EGJOO requires meeting the criteria of elevated median-IRP during upright wet swallows and elevated intrabolus pressure. However, with the diagnostic criteria modification, the change in manometric features of EGJOO remained unclear. AIM: To evaluate the esophageal motility characteristics of patients with EGJOO and select valuable parameters for confirming the diagnosis of EGJOO. METHODS: We performed a retrospective analysis of 370 patients who underwent high-resolution manometry with 5 mL water swallows × 10 in supine, × 5 in upright position and the rapid drink challenge (RDC) with 200 mL water from November 2016 to November 2021 at Peking University First Hospital. Fifty-one patients with elevated integrated supine IRP and evidence of peristalsis were enrolled, with 24 patients meeting the updated manometric EGJOO diagnosis (CCv4.0) as the EGJOO group and 27 patients not meeting the updated EGJOO criteria as the isolated supine IRP elevated group (either normal median IRP in upright position or less than 20% of supine swallows with elevated IBP). Forty-six patients with normal manometric features were collected as the normal high-resolution manometry (HRM) group. Upper esophageal sphincter (UES), esophageal body, and lower esophageal sphincter (LES) parameters were compared between groups. RESULTS: Compared with the normal HRM group, patients with EGJOO (CCv4.0) had significantly lower proximal esophageal contractile integral (PECI) and proximal esophageal length (PEL), with elevated IRP on RDC (P < 0.05 for each comparison), while isolated supine IRP elevated patients had no such feature. Patients with EGJOO also had more significant abnormalities in the esophagogastric junction than isolated supine IRP elevated patients, including higher LES resting pressure (LESP), intrabolus pressure, median supine IRP, median upright IRP, and IRP on RDC (P < 0.05 for each comparison). Patients with dysphagia had significantly lower PECI and PEL than patients without dysphagia among the fifty-one with elevated supine IRP. Further multivariate analysis revealed that PEL, LESP, and IRP on RDC are factors associated with EGJOO. The receiver-operating characteristic analysis showed UES nadir pressure, PEL, PECI, LESP, and IRP on RDC are parameters supportive for confirming the diagnosis of EGJOO. CONCLUSION: Based on CCv4.0, patients with EGJOO have more severe esophagogastric junction dysfunction and are implicated in the proximal esophagus. Additionally, several parameters are supportive for confirming the diagnosis of EGJOO.

Pattern-based approach to gastritis and gastropathy.

Histological investigation of non-neoplastic endoscopic biopsies of gastric mucosa is one of the most common tasks most pathologists have to face on daily basis. Although the most common clinical question is still being whether Helicobacter organisms are found, pathologists have to bear in mind the whole spectrum of causes and associated morphological patterns of gastritides and gastropathies, governed by characteristic combinations of various types of inflammatory infiltrate, alterative and reactive changes of epithelial component, vascular response, and variability of stromal composition. The association of histopathologic pattern with supposed etiology can be sometimes proved by direct detection of the cause of morphologic changes in the investigated endoscopic sample.

The relationship between portal hypertension and portal hypertensive gastropathy.

BACKGROUND AND AIM: Portal hypertensive gastropathy (PHG) most commonly occurs in the setting of increased portal pressure in patients with cirrhosis. Here, we aimed to understand the correlation between hepatic venous pressure gradient (HVPG) and the presence and severity of PHG in patients with cirrhosis. METHODS: We examined patients with cirrhosis who underwent HVPG measurement at the Medical University of South Carolina between 2014 and 2020. Extensive demographic, clinical, laboratory, procedural (including precise grading of PHG severity using standard definitions), and outcome data were abstracted at the time of HVPG measurement. RESULTS: Three hundred and ten patients with HVPG measurements and cirrhosis were identified. Seventy-three patients having endoscopy within 6 months of HVPG measurement were included (mean age 54 ± 11, 44% female). The most common causes of cirrhosis were alcohol (41%) and non-alcoholic steatohepatitis (32%). The average HVPG was 15 mmHg (±6) and 62 patients had clinically significant portal hypertension (CSPH) (HVPG ≥ 10 mmHg). Of the 73 patients with HVPG measured, 45 (62%) had PHG, including 40 (89%) of whom had CSPH. Out of the 45 patients with PHG, 41 and four had mild or severe PHG, respectively. MELD scores were similar in patients with and without PHG [15 ± 9 (SD) and 17 ± 9, respectively; p = .37]. HVPG was higher in patients with PHG (17 ± 7 mmHg) than those without PHG (13 ± 4 mmHg) (p = .01) but did not differ between mild and severe PHG. CONCLUSION: A weak correlation exists between HVPG level and the presence of PHG.

Can FLIP guide therapy in idiopathic esophagogastric junction outflow obstruction?

BACKGROUND: Esophagogastric junction outflow obstruction (EGJOO) has a variable disease course. Currently, barium swallow (BaS) and manometric parameters are used to characterize clinically significant EGJOO. The esophagogastric junction distensibility index (EGJ-DI) measured via functional lumen imaging probe (FLIP) can provide complementary information. Our aim was to assess symptom response in patients with EGJOO and an abnormal EGJ-DI after botulinum toxin (BT) treatment. METHODS: A prospective cohort study of adults with idiopathic EGJOO was performed from September 2019 to March 2021. Patients with dysphagia underwent upper endoscopy with FLIP. If the EGJ-DI was abnormally low, BT was injected. Data examined included demographics, medical history, endoscopic and FLIP findings, BaS, manometry, and Eckardt score (ES). ES improvement was assessed via paired samples t-test. Pearson's chi-square tests were used to assess for associations. RESULTS: Of the 20 patients, 75% had an abnormal EGJ-DI and underwent BT injections. Mean ES for patients with abnormal EGJ-DIs significantly improved from baseline to 1, 3, and 6 month follow-up (P-values: 0.01, 0.05, and 0.02, respectively). There was a significant association between an abnormal EGJ-DI with delayed bolus transit and presence of rapid drink challenge panesophageal pressurization on manometry: P = 0.03 and P = 0.03. CONCLUSION: This prospective study revealed that an abnormal EGJ-DI can guide BT as assessed via symptomatic response. Additionally, abnormal EGJ-DI measurements were significantly associated with other parameters used previously to determine clinically relevant EGJOO. Larger follow-up studies are warranted to further elucidate guidance for therapy in EGJOO.

Menetrier's disease exacerbating ulcerative colitis and relieved by gastrectomy.

Ménétrier's disease (MD) is a rare gastropathy characterised by giant rugal folds which can present with nausea, vomiting, abdominal pain and protein losing gastropathy. We report a 21-year-old woman with comorbid MD and ulcerative colitis (UC). Management was complicated by limited treatment options for MD, significant symptom burden, worsening nutrition and difficulty determining which disease was the predominant cause of symptoms. Since age 18 the patient experienced recurrent UC flares characterised by diarrhoea, persistent vomiting and corticosteroid dependence. Endoscopic assessment demonstrated concurrent MD and active UC. Octreotide and cetuximab were trialled given persistent hypoalbuminaemia and suspicion for MD associated protein-losing gastropathy. UC management comprised dose-optimised infliximab and methotrexate. Repeat endoscopic assessment demonstrated improvement in UC without corresponding improvement in symptoms or hypoalbuminaemia. Nasojejunal feeding and parenteral nutrition failed to significantly improve nutritional status and accordingly the patient proceeded to radical total gastrectomy. Postoperatively, MD-associated symptoms and hypoalbuminemia resolved completely.

Mitochondrial DNA Haplogroup Related to the Prevalence of Helicobacter pylori.

Mitochondria are essential organelles that are not only responsible for energy production but are also involved in cell metabolism, calcium homeostasis, and apoptosis. Targeting mitochondria is a key strategy for bacteria to subvert host cells' physiology and promote infection. Helicobacter (H.) pylori targets mitochondria directly. However, mitochondrial genome (mtDNA) polymorphism (haplogroup) is not yet considered an important factor for H. pylori infection. Here, we clarified the association of mitochondrial haplogroups with H. pylori prevalence and the ability to perform damage. Seven mtDNA haplogroups were identified among 28 H. pylori-positive subjects. Haplogroup B was present at a higher frequency and haplotype D at a lower one in the H. pylori population than in that of the H. pylori-negative one. The fibroblasts carrying high-frequency haplogroup displayed a higher apoptotic rate and diminished mitochondrial respiration following H. pylori infection. mtDNA mutations were accumulated more in the H. pylori-positive population than in that of the H. pylori-negative one in old age. Among the mutations, 57% were located in RNA genes or nonsynonymous protein-coding regions in the H. pylori-positive population, while 35% were in the H. pylori-negative one. We concluded that gastric disease caused by Helicobacter virulence could be associated with haplogroups and mtDNA mutations.

Ink stained gastric lesions: a rare cause of gastrointestinal bleeding.

A 61-year-old male was hospitalized in our department due to Intermittent melena for 4 days. Laboratory tests showed a reduced hemoglobin level (10.7 g/L). Abdominal computed tomography (CT) showed gastric wall thickening in the gastric body.

Clinical associations of functional dyspepsia with gastric dysrhythmia on electrogastrography: A comprehensive systematic review and meta-analysis.

BACKGROUND: Functional dyspepsia (FD) is a common gastroduodenal disorder, yet its pathophysiology remains poorly understood. Bioelectrical gastric slow-wave abnormalities are thought to contribute to its multifactorial pathophysiology. Electrogastrography (EGG) has been used to record gastric electrical activity; however, the clinical associations require further evaluation. AIMS: This study aimed to systematically assess the clinical associations of EGG in FD. METHODS: MEDLINE, EMBASE, and CENTRAL databases were systematically searched for articles using EGG in adults with FD. Primary outcomes were percentage normal versus abnormal rhythm (bradygastria, normogastria, and tachygastria). Secondary outcomes were dominant power, dominant frequency, percentage coupling, and the meal responses. RESULTS: 1751 FD patients and 555 controls from 47 studies were included. FD patients spent less time in normogastria while fasted (SMD -0.74; 95%CI -1.22 to -0.25) and postprandially (-0.86; 95%CI -1.35 to -0.37) compared with controls. FD patients also spent more fasted time in bradygastria (0.63; 95%CI 0.33-0.93) and tachygastria (0.45; 95%CI 0.12-0.78%). The power ratio (-0.17; 95%CI -0.83-0.48) and dominant frequency meal-response ratio (0.06; 95%CI -0.08-0.21) were not significantly different to controls. Correlations between EGG metrics and the presence and timing of FD symptoms were inconsistent. EGG methodologies were diverse and variably applied. CONCLUSION: Abnormal gastric slow-wave rhythms are a consistent abnormality present in FD, as defined by EGG and, therefore, likely play a role in pathophysiology. The aberrant electrophysiology identified in FD warrants further investigation, including into underlying mechanisms, associated spatial patterns, and symptom correlations.

Prenatal diagnosis of left side congenital diaphragmatic hernia associated with gastric perforation.

OBJECTIVE: A congenital diaphragmatic hernia (CDH) complicated with gastric perforation is extremely rare. Herein, we report an unusual case of unexpected intrauterine gastric perforation of a left side CDH with concurrent pleural effusion and ascites. CASE REPORT: A 21-year-old female underwent prenatal ultrasound at 37 weeks of gestation and revealed a left side CDH, pleural effusion with a large thick-walled cystic mass over the left thorax, ascites, and polyhydramnios. Under the impression of CDH with suspected gastric perforation, Cesarean delivery was arranged and a male neonate was delivered. The neonate received emergency laparotomy soon and a herniation originated from the foramen of Bochdalek and a perforation located in the stomach body along the greater curvature were found. The pathologic diagnosis was consistent with a spontaneous gastric perforation with ischemic change. CONCLUSION: Sonographic findings of pleural effusion and ascites associated with CDH are clues of antenatal gastrointestinal perforation.
