Postpolypectomy syndrome without abdominal pain led to sepsis/septic shock and gastrointestinal bleeding:A case report

BACKGROUND Postpolypectomy syndrome(PPS)is a rare postoperative complication of colonic polypectomy.It presents with abdominal pain and fever accompanied by coagulopathy and elevated inflammatory markers.Its prognosis is usually good,and it only requires outpatient treatment or observation in a general ward.How-ever,it can be life-threatening.CASE SUMMARY The patient was a 58-year-old man who underwent two colonic polypectomies,each resulting in life-threatening sepsis,septic shock,and coagulopathy.Each of the notable manifestations was a rapid drop in blood pressure,an increase in heart rate,loss of consciousness,and heavy sweating,accompanied by shortness of breath and decreased oxygen in the finger pulse.Based on the criteria of organ dysfunction due to infection,we diagnosed him with sepsis.The patient also experienced severe gastrointestinal bleeding after the second operation.Curiously,he did not complain of any abdominal pain throughout the course of the illness.He had significantly elevated concentrations of inflammatory markers and coagulopathy.Except for the absence of abdominal pain,his fever,significant coagulopathy,and elevated inflammatory marker concentrations were all consistent with PPS.Abdominal computed tomography and superior mesenteric artery computed tomography angiography showed no free air or vascular damage.Thus,the diagnosis of colon perforation was not considered.The final blood culture results indicated Moraxella osloensis.The patient was transferred to the intensive care unit and quickly improved after fluid resuscitation,antibiotic treatment,oxygen therapy,and blood transfusion.CONCLUSION PPS may induce dysregulation of the systemic inflammatory response,which can lead to sepsis or septic shock,even in the absence of abdominal pain.

Esophageal ulcer and multisystem inflammatory syndrome after COVID-19:A case report

BACKGROUND Multisystem inflammatory syndrome in adults(MIS-A)is a rare but severe disease occurring several weeks after severe acute respiratory syndrome coronavirus 2 infection.It develops in adults with inflammation of different organs including the gastrointestinal tract,heart,kidneys,skin and hematopoietic system.CASE SUMMARY We present a 58-year-old Chinese man diagnosed with MIS-A.His chief complaints were fever,generalized fatigue and anorexia,accompanied with rashes on his back.Further examination showed cardiac,renal and liver injury.He had melena and gastroscopy indicated esophageal ulcer and severe esophagitis.Repeated blood and sputum culture did not show growth of bacteria or fungi.Antibiotic treatment was stopped due to unsatisfactory performance.His condition improved after prednisone and other supportive treatment.CONCLUSION Gastrointestinal involvement in MIS-A is not uncommon.Intestinal involvement predominates,and esophageal involvement is rarely reported.Esophageal ulcer with bleeding could also be a manifestation of MIS-A.

Bleeding risk assessment in elderly patients with acute coronary syndrome

Nowadays,elderly people represent a growing population segment with a well known increased risk of both ischemic and bleeding events.Current acute coronary syndrome guidelines,strongly recommend dual antiplatelet therapy(DAPT)with few specific references for aged patients due to lack of evidence.Patients aged>75 years are misrepresented in the classic derivation trials cohorts.Strategies to reduce the bleeding risk in this group of patients are urgently needed for the daily clinical practice.Identify the specific age related bleeding risk factors and the importance of an integral geriatric assessment remains challenging.Some of the available in-hospital and out-hospital bleeding risk scores have shown a lower to moderate predictive ability in older patients and no specific tools are developed in elderly population.The importance of an appropriate vascular access choice,type and duration of antiplatelet drugs is crucial to reduce the bleeding risk.Increase radial approaches and short DAPT duration leads to reduce hemorrhages.One interesting subgroup of patients is those who need chronic anticoagulation therapy after percutaneous coronary intervention,due to their very high risk of bleeding.New alternatives as dual therapy with oral anticoagulation and only one antiplatlet drug should be considered.In current review,we evaluate the available evidence about bleeding risk in elderly.

Klippel-Trenaunay syndrome with gastrointestinal bleeding,splenic hemangiomas and left inferior vena cava

Klippel-Trenaunay syndrome is a congenital vascular anomaly characterized by a triad of varicose veins,cutaneous capillary malformation,and hypertrophy of bone and(or)soft tissue.Gastrointestinal vascular malformations in Klippel-Trenaunay syndrome may present with gastrointestinal bleeding.The majority of patients with spleenic hemangiomatosis and/or left inferior vena cava are asymptomatic.We herein report a case admitted to the gastroenterology clinic with life-threatening hematochezia and symptomatic iron deficiency anemia.Due to the asymptomatic mild intermittent hematochezia,splenic hemangiomas and left inferior vena cava,the patient did not seek any help for gastrointestinal bleeding until his admittance to our department for evaluation of massive gastrointestinal bleeding.He was referred to angiography because of his serious pathogenetic condition and inefficiency of medical therapy.The method showed that hemostasis was successfully achieved in the hemorrhage site by embolism of corresponding vessels.Further endoscopy revealed vascular malformations starting from the stomach to the descending colon.On the other hand,computed tomography revealed splenic hemangiomas and left inferior vena cava.To the best of our knowledge,this is the first Klippel-Trenaunay syndrome case presenting with gastrointestinal bleeding,splenic hemangiomas and left inferior vena cava.The literature on the evaluation and management of this case is reviewed.

Terlipressin improves pulmonary pressures in cirrhotic patients with pulmonary hypertension and variceal bleeding or hepatorenal syndrome

Terlipressin has been shown to improve both pulmonary and systemic hemodynamics in stable cirrhotic patients with pulmonary hypertension,whereas other vasoconstrictors may cause pulmonary pressures to deteriorate We investigated the pulmonary and systemic hemodynamic effects of the first terlipressin dose(2 mg) in 7 cirrhotic patients with PH presenting with variceal bleeding(n=4) or hepatorenal syndrome(n=3).Terlipressin decreased pulmonary vascular resistance(158.8±8.9 vs 186.5±13.9 dynes sec cm-5 ;P=0.003) together with an increase in systemic vascular resistance(2143± 126 vs 1643±126 dynes sec cm-5 ;P<0.001).Terlipressin should be the vasoconstrictor treatment of choice when patients present with variceal bleeding or HRS.

Unusual complication in patient with Gardner's syndrome: Coexistence of triple gastrointestinal perforation and lower gastrointestinal bleeding: A case report and review of literature

Gardner's syndrome(GS) is a rare syndrome with autosomal dominant inheritance, which is characterized by multiple intestinal polyps, dental anomalies, desmoid tumors, and soft tissue tumors. All gastrointestinal symptoms seen in GS are associated with the underlying familial adenomatosis polyposis and abdominal desmoid tumors, with the most common symptoms being anemia, lower gastrointestinal bleeding, abdominal pain, diarrhea, obstruction, and mucous defecation. To our best knowledge, no case of GS that has presented with gastrointestinal perforation and bleeding has ever been reported in the English language medical literature. A 37-year-old male who had been diagnosed with GS five years earlier was referred to our clinic for lower gastrointestinal bleeding. Despite the absence of a bleeding focus on conventional angiography, the patient was operated on with laparotomy, due to the persistence of both signs and symptoms of mild peritonitis. On the laparotomy, the patient was noted to have areas of perforation in the duodenum, splenic flexura, and midrectum. The third and fourth part of the duodenum, the proximal 15 cm segment of the jejunum, a 10 cm segment of the terminal ileum, the whole colon, and the upper and middle rectum were resected, and duodenojejunal side-to-side anastomosis and terminal ileostomy were performed. The histopathological analysis of the large mass measuring 30 cm × 20 cm was reported as a desmoid tumor. The pathological examination of the tumor foci detected in the colonic specimen revealed poorly differentiated adenosquamous carcinoma.

Safety of gastrointestinal endoscopy in patients with acute coronary syndrome and concomitant gastrointestinal bleeding

BACKGROUND Gastrointestinal bleeding(GIB)is a major concern in patients hospitalized with acute coronary syndrome(ACS)due to the common use of both antiplatelet medications and anticoagulants.Studies evaluating the safety of gastrointestinal endoscopy(GIE)in ACS patients with GIB are limited by their relatively small size,and the focus has generally been on upper GIB and esophago-gastroduodenoscopy(EGD)only.AIM To evaluate the safety profile and the hospitalization outcomes of undergoing GIE in patients with ACS and concomitant GIB using the national database for hospitalized patients in the United States.METHODS The Nationwide Inpatient Sample database was queried to identify patients hospitalized with ACS and GIB during the same admission between 2005 and 2014.The International Classification of Diseases Code,9th Revision Clinical Modification was utilized for patient identification.Patients were further classified into two groups based on undergoing endoscopic procedures(EGD,small intestinal endoscopy,colonoscopy,or flexible sigmoidoscopy).Both groups were compared regarding demographic information,outcomes,and comorbidities.Multivariate analysis was conducted to identify factors associated with mortality and prolonged length of stay.Chi-square test was used to compare categorical variables,while Student’s t-test was used to compare continuous variables.All analyses were performed using SAS 9.4(Cary,NC,United States).RESULTS A total of 35612318 patients with ACS were identified between January 2005 and December 2014.269483(0.75%)of the patients diagnosed with ACS developed concomitant GIB during the same admission.At least one endoscopic procedure was performed in 68%of the patients admitted with both ACS and GIB.Patients who underwent GIE during the index hospitalization with ACS and GIB had lower mortality(3.8%)compared to the group not undergoing endoscopy(8.6%,P<0.001).A shorter length of stay(LOS)was observed in patients who underwent GIE(mean 6.59±7.81 d)compared to the group not undergoing endoscopy(mean 7.84±9.73 d,P<0.001).Multivariate analysis showed that performing GIE was associated with lower mortality(odds ratio:0.58,P<0.001)and shorter LOS(-0.36 factor,P<0.001).CONCLUSION Performing GIE during the index hospitalization of patients with ACS and GIB was correlated with a better mortality rate and a shorter LOS.Approximately twothirds of patients with both ACS and GIB undergo GIE during the same hospitalization.

Treatment of severe upper gastrointestinal bleeding caused by Mallory-Weiss syndrome after primary coronary intervention for acute inferior wall myocardial infarction: A case report

BACKGROUND Upper gastrointestinal bleeding(UGIB) after an acute myocardial infarction(AMI) is not an uncommon complication. Acute UGIB caused by Mallory-Weiss syndrome(MWS) is usually a dire situation with massive bleeding and hemodynamic instability. Acute UGIB caused by MWS after an AMI has not been previously reported.CASE SUMMARY A 57-year-old man with acute inferior wall ST elevation myocardial infarction underwent a primary coronary intervention of the acutely occluded right coronary artery. Six hours after the intervention, the patient had a severe UGIB,followed by vomiting. His hemoglobin level dropped from 15.3 g/d L to 9.7 g/d L. In addition to blood transfusion and a gastric acid inhibition treatment,early endoscopy was employed and MWS was diagnosed. Bleeding was stopped by endoscopic placement of titanium clips.CONCLUSION Bleeding complications after stent implantation can pose a dilemma. MWS is a rare but severe cause of acute UGIB after an AMI that requires an early endoscopic diagnosis and a hemoclip intervention to stop bleeding.

Bleeding risk stratification in an era of aggressive management of acute coronary syndromes

Major bleeding is currently one of the most common non-cardiac complications observed in the treatment of patients with acute coronary syndrome(ACS). Hemorrhagic complications occur with a frequency of 1% to 10% during treatment for ACS. In fact, bleeding events are the most common extrinsic complication associated with ACS therapy. The identification of clinical characteristics and particularities of the antithrombin therapy associated with an increased risk of hemorrhagic complications would make it possible to adopt prevention strategies, especially among those exposed to greater risk. The international societies of cardiology renewed emphasis on bleeding risk stratification in order to decide strategy and therapy for patients with ACS. With this review, we performed an update about the ACS bleeding risk scores most frequently used in daily clinical practice.

A Study of Mallory-Weiss Syndrome Secondary to Upper Gastrointestinal Bleeding

Background: In Mallory-Weiss Syndrome (MWS), vomiting causes the mucous membrane and submucosa near the esophagogastric mucosal junction to tear and bleed. Thus, MWS can arise after heavy drinking and as a complication of endoscopic upper gastrointestinal examinations or procedures. However, there has been no report of MWS secondary to upper gastrointestinal bleeding thus far. Case Subjects: Of 79 MWS cases over a 10-year period from 2002 to 2011, we identified and studied 6 cases, in which MWS was probably caused by another lesion causing upper gastrointestinal bleeding. Results: There were 2 cases, each of gastric ulcers, duodenal ulcers, and varicose veins. In 3 cases, MWS was discovered during treatment of the primary lesion and was simultaneously treated. In the other 3 cases, patients were treated for MWS according to endoscopic diagnosis, and the primary lesion was overlooked;in these cases, the primary lesion was identified and treated after the bleeding recurred. One patient with cirrhosis died of hepatic failure. Conclusion: Care should be taken when dealing with MWS because it can occur as a result of vomiting caused by hematemesis or as a complication of endoscopic examination and treatment. When assessing MWS, other hemorrhagic lesions may be overlooked.

Klippel-Trenaunay Syndrome: A Rare Cause of Vaginal Bleeding in the Prepubescent Girl

Klippel-Trénaunay syndrome (KTS) is an uncommon congenital disorder with unknown etiology that consists of mixed vascular malformations. Visceral organs may also be involved leading to a variety of manifestations. Although seemingly uncommon, genital tract involvement can occur and be a source of significant morbidity. We hereby describe a case of KTS of a 7-year-old female patient presenting with genital bleeding, large venous and capillary malformations and soft tissue hypertrophy of right limb. Patient was treated conservatively and asked to follow-up regularly. KTS should be kept on mind as a cause of vaginal bleeding in preteen girls especially those with suggestive clinical features. Management of this complex condition is challenging because of its progressive nature and wide range of disease severity.

Mallory-Weiss syndrome from giant gastric trichobezoar: A case report

BACKGROUND Mallory-Weiss syndrome(MWS),representing a linear mucosal laceration at the gastroesophageal junction,is a quite frequent cause of upper gastrointestinal bleeding,usually induced by habitual vomiting.The subsequent cardiac ulceration in this condition is likely due to the concomitance of increased intragastric pressure and inappropriate closure of the gastroesophageal sphincter,collectively inducing ischemic mucosal damage.Usually,MWS is associated with all vomiting conditions,but it has also been described as a complication of prolonged endoscopic procedures or ingested foreign bodies.CASE SUMMARY We described herein a case of upper gastrointestinal bleeding in a 16-year-old girl with MWS and chronic psychiatric distress,the latter of which deteriorated following her parents’divorce.The patient,who was residing on a small island during the coronavirus disease 2019 pandemic lockdown period,presented with a 2-mo history of habitual vomiting,hematemesis,and a slight depressive mood.Ultimately,a huge intragastric obstructive trichobezoar was detected and discovered to be due to a hidden habit of continuously eating her own hair;this habit had persisted for the past 5 years until a drastic reduction in food intake and corresponding weight loss occurred.The relative isolation in her living status without school attendance had worsened her compulsory habit.The hair agglomeration had reached such enormous dimensions and its firmness was so hard that its potential for endoscopic treatment was judged to be impossible.The patient underwent surgical intervention instead,which culminated in complete removal of the mass.CONCLUSION According to our knowledge,this is the first-ever described case of MWS due to an excessively large trichobezoar.

Blue rubber bleb nevus syndrome:A case report and literature review

Blue rubber bleb nevus syndrome(BRBNS)is a rare disease characterized by multiple venous malformations and hemangiomas in the skin and visceral organs.The lesions often involve the cutaneous and gastrointestinal systems.Other organs can also be involved,such as the central nervous system,liver,and muscles.The most common symptoms are gastrointestinal bleeding and secondary iron deficiency anemia.The syndrome may also present with severe complications such as rupture,intestinal torsion,and intussusception,and can even cause death.Cutaneous malformations are usually asymptomatic and do not require treatment.The treatment of gastrointestinal lesions is determined by the extent of intestinal involvement and severity of the disease.Most patients respond to supportive therapy,such as iron supplementation and blood transfusion.For more significant hemorrhages or severe complications,surgical resection,endoscopic sclerosis,and laser photocoagulation have been proposed.Here we present a case of BRBNS in a 45-year-old woman involving 16sites including the scalp,eyelid,orbit,lip,tongue,face,back,upper and lower limbs,buttocks,root of neck,clavicle area,superior mediastinum,glottis,esophagus,colon,and anus,with secondary severe anemia.In addition,we summarize the epidemiology,clinical manifestations,diagnosis,differential diagnosis and therapies of this disease by analyzing all previously reported cases to enhance the awareness of this syndrome.

Solitary rectal ulcer syndrome presenting as polypoid mass lesions in a young girl

Solitary rectal ulcer syndrome (SRUS) is a rare condition in children. We report a case of SRUS in an 8-year old Saudi girl who presented with recurrent rectal bleeding,intermittent mucosal prolapse,and passage of mucus per rectum. Colonoscopy revealed multiple polypoid mass lesions with histopathological features of SRUS. The polypoid variant of SRUS is very rare in children and may be confused with rectal malignant or inflammatory conditions.

Bevacizumab and gastrointestinal bleeding in hereditary hemorrhagic telangiectasia

We report a case of severe, refractory gastrointestinal(GI) bleeding in a patient with hereditary hemorrhagic telangiectasia(HHT) whose massive transfusion dependence was lifted shortly after treatment with bevacizumab, an anti-vascular endothelial growth factor. The patient's bleeding had been refractory to repeated endoscopic interventions, tranexamic acid, and tamoxifen. However, following treatment with bevacizumab at 5 mg/kg every other week, nearly 300 units of packed red blood cell transfusions were avoided in one year's time. Despite its relatively high cost, bevacizumab may have a more active role in the management of severe GI bleeding in HHT if such remarkable response can be consistently demonstrated.

Rare case of upper gastrointestinal bleeding in achalasia

Achalasia is a prototypic esophageal motility disorder with complications including aspiration-pneumonia, esophagitis, esophageal-tracheal fistula, spontaneous rupture of the esophagus, and squamous cell carcinoma. However, achalasia is rarely associated with esophageal stones and ulcer formation that lead to upper gastrointestinal bleeding. Here, we report the case of a 61-year-old woman who was admitted to our department aftervomiting blood for six hours. Physical examination revealed that the patient had severe anemia and mild palpitation in the upper abdomen. CT revealed lower esophageal dilatation and esophageal wall thickening, and an emergency upper endoscopy showed that the esophagus was substantially expanded by a dark round stone, with multiple ulcers on the esophageal wall and a slit in the cardiac mucosa with a large clot attached. The patient's history included ingestion of 1 kg hawthorn three days prior. The acute upper gastrointestinal bleeding was caused by Mallory-Weiss syndrome associated with achalasia and an esophageal stone. For patients with achalasia, preventing excessive ingestion of tannins is crucial to avoid complications such as bleeding and rupture.

Portal hypertension and gastrointestinal bleeding:Diagnosis,prevention and management

Bleeding from esophageal varices is a life threatening complication of portal hypertension.Primary prevention of bleeding in patients at risk for a first bleeding episode is therefore a major goal.Medical prophylaxis consists of non-selective beta-blockers like propranolol or carvedilol.Variceal endoscopic band ligation is equally effective but procedure related morbidity is a drawback of the method.Therapy of acute bleeding is based on three strategies:vasopressor drugs like terlipressin,antibiotics and endoscopic therapy.In refractory bleeding,self-expandable stents offer an option for bridging to definite treatments like transjugular intrahepatic portosystemic shunt(TIPS).Treatment of bleeding from gastric varices depends on vasopressor drugs and on injection of varices with cyanoacrylate.Strategies for primary or secondary prevention are based on non-selective beta-blockers but data from large clinical trials is lacking.Therapy of refractory bleeding relies on shuntprocedures like TIPS.Bleeding from ectopic varices,portal hypertensive gastropathy and gastric antral vascular ectasia-syndrome is less common.Possible medical and endoscopic treatment options are discussed.

In-hospital outcome of elderly patients with acute coronary syndromes treated with platelet glycoproteinⅡb/Ⅲa blockers

Background and objective The safety of intravenous glycoproteinⅡb/Ⅲa inhibitors (GPI) in elderly patients admitted with acute coronary syndrome (ACS) has not yet been established. The purpose of this study was to evaluate the safety of GPI in elderly patients with ACS. Methods Ninety consecutive patients≥70 years of age admitted to a county hospital between 1999-2004 were included. All patients had typical ACS symptoms along with high-risk markers. Results There was no difference in the TIMI risk score between patients who received GPI (n=47) and those who did not (n=43). Patients who received GPI had a lower creatinine clearance (40 cc/min vs. 47cc/min, p= 0.04). Patients who received GPI had a lower incidence of death, reinfarction or major bleeding (19% vs. 4%, p=0.03). There was no significant difference in major bleeding between the 2 groups. None of the patients in either group developed thrombocytopenia. Conclusion This retrospective small study suggests that the use of GPI in a selected group of elderly patients with acute coronary syndrome may be safe. (J Geriatr Cardiol 2005; 2(4):203-205 )

STUDIES ON THE LUMINESCENCE OF CHANNELS IN RATS AND ITS LAW OF CHANGES WITH“SYNDROMES”AND TREATMENT OF ACUPUNCTURE AND MOXIBUSTION

We previously reported the discovery of 14 channels in the human body,which possessed thebiophysical property of high emission of light.In this study we found the same property on theRen and Du channels in healthy rats.Additionally,we discovered that the luminance of the relat-ed channels in rat models with different“syndromes”varied greatly.For instance,a markedlylow luminance appeared on the Du channel in animals with experimental syndrome of Yang defi-ciency induced by hydrocortisone;while in animals with experimental syndrome of blood deft-ciency caused by bleeding,an apparently low luminance occurred on the Ren channel.The inten-sity of the emitted light on Du and Ren channels increased after acupuncture treatment,but notsignificantly.This phenomenon conforms to the theory in traditional Chinese medicine that theDu channel is the“sea of Yang channels”,while the Ren channel is the“sea of Yin channels”.

Aortic Valve Replacement for Patients with Heyde Syndrome:A Literature Review

Objective To explore the characteristics and clinical outcomes of patients with Heyde syndrome(HS)who undergo aortic valve replacement(AVR).Methods Electronic databases including Pub Med,Embase,Ovid,WANFANG,VIP and CNKI were searched to identify all case reports of HS patients undergoing AVR surgery,using different combinations of search terms"Heyde syndrome","gastrointestinal bleeding","aortic stenosis",and"surgery".Three authors independently extracted the clinical data including the patients’characteristics,aortic stenosis severity,gastrointestinal bleeding sites,surgical treatments and prognosis.Results Finally,46 case reports with 55 patients aging from 46 to 87 years,were determined eligible and included.Of them,1 patient had mild aortic stenosis,1 had moderate aortic stenosis,42 had severe aortic stenosis,and 11 were not mentioned.Gastrointestinal bleeding was detected in colon(n=8),jejunum(n=6),ileum(n=4),cecum(n=3),duodenal(n=3)and multiple sites(n=8).No specific bleeding site was identified in 23 patients.Preoperative hemoglobin level ranged from 43 to 117 g/L.All but one of 16 patients showed decreased level of high molecule weight von Willebrand factor.Of the 55 patients,43 underwent AVR,and 12 received transcatheter AVR.Aortic valves of 14 cases were replaced by mechanical valves,and 33 cases by biological valves.All patients recovered well during the follow-up,except 5 patients.One patient who had perivalvular leakage and gastrointestinal bleeding after AVR underwent the second AVR.Two patients had recurrent gastrointestinal bleeding.Two patients died of life-threatening acute subdural hematoma and multiple organ failure,respectively.Conclusions HS is a rare syndrome characterized by aortic stenosis and gastrointestinal bleeding.AVR is an effective treatment for HS.
