Mallory-Weiss syndrome: clinical and endoscopic characteristics

A Systematic Analysis of Incidence, Therapeutic Strategies, and In-hospital Mortality of Mallory-Weiss Syndrome in Germany

BACKGROUND

Mallory-Weiss syndrome (MWS) is a rare cause of upper gastrointestinal bleeding from gaging or vomiting-induced mucosal lacerations at the gastroesophageal junction. Most cases do not require urgent endoscopic intervention due to the mostly self-limiting course. For more severe cases, different hemostasis techniques have been used. In small MWS cohorts, overall mortality was ~5%, but comprehensive data, as well as population-based incidence, treatment recommendations, and outcome parameters such as in-hospital mortality and adverse events, are largely lacking.

METHODS

We evaluated current epidemiological trends, therapeutic strategies, and in-hospital Mortality of MWS in Germany based on standardized hospital discharge data provided by the German Federal Statistical Office from 2010 to 2019.

RESULTS

A total of 59,291 MWS cases, predominately male (62%), were included into analysis. The mean number of MWS cases in Germany was 5929/year and decreased continuously during the observation period (-4.1%/y). The overall annual incidence rate (as hospitalization cases per 100,000 persons) was 7.5 with the highest incidence rate in the New Federal States (8.7). The most common comorbidities were reflux esophagitis (23.6%), diaphragmatic hernia (19.7%), and alcohol abuse (10.9%). The most frequent complication was bleeding anemia (26%), whereas hypovolemic shock (2.9%) was rare. Endoscopic injection was the most commonly performed endoscopic therapy (13.7%), followed by endoscopic clipping (12.8%), whereas the need for surgical therapy was rare (0.1%). Endoscopic combination therapies were used predominantly as a combination of injection and clipping. The overall in-hospital mortality was 2.7% and did not differ through the observation period. The presence of hypovolemic shock, acute kidney injury, sepsis, artificial ventilation, adult respiratory distress syndrome, bleeding anemia, and female sex was associated with a significantly worse prognosis.

CONCLUSION

Our study gives a detailed insight into the incidence, patient-related risk factors, endoscopic treatment, and overall in-hospital mortality as well as regional differences in a large MWS collective in Germany. Furthermore, we were able to identify mortality-associated complications and their impact.

The prediction value of scoring systems in Mallory-Weiss syndrome patients

Mallory-Weiss syndrome (MWS) is a relatively less common cause of nonvariceal upper gastrointestinal bleeding. There is limited data on whether scoring systems could be used to predict the clinical outcomes in patients with bleeding due to MWS. The aim of our study is to evaluate whether the Glasgow-Blatchford score (GBS), AIMS65, and shocking index are effective in predicting the clinical outcomes of MWS.One hundred twenty-eight patients from January 2010 to January 2017 with MWS in middle China were enrolled. Clinical features such as age, gender, causes of vomiting, endoscopic findings, GBS, AIMS65, and shocking index were recorded. The clinical outcomes including endoscopic treatment and transfusion were analyzed.MWS accounted for 6.1% of nonvariceal upper gastrointestinal bleeding. Male-to-female ratio was 3.6:1 and median age was 51 years. Patients between 40 and 60 years were more commonly affected; 43.8% of MWS was caused by overdrinking followed by underlying gastric diseases (33.6%). However, for female patients alone, underlying gastric diseases were the leading cause (42.9%). The tears were usually single and most frequently located on the left lateral wall. In receiver-operating characteristic curve analyses, GBS system and shocking index were useful in predicting transfusion (0.856 vs 0.675). But for endoscopic intervention, these scoring systems are not helpful (P > .05).Apart from drinking, underlying gastric disease is another important cause of MWS especially for female patients and should be paid more attention under endoscopy examination. GBS system and shocking index can be used to predict transfusion.

Nonvariceal Upper Gastrointestinal Bleeding

In the intensive care unit, vigilance is needed to manage nonvariceal upper gastrointestinal bleeding. A focused history and physical examination must be completed to identify inciting factors and the need for hemodynamic stabilization. Although not universally used, risk stratification tools such as the Blatchford and Rockall scores can facilitate triage and management. Urgent evaluation for nonvariceal upper gastrointestinal bleeds requires prompt respiratory assessment, and identification of hemodynamic instability with fluid resuscitation and blood transfusions if necessary. Future studies are needed to evaluate the indication, safety, and efficacy of emerging endoscopic techniques.

Distinctive aspects of peptic ulcer disease, Dieulafoy's lesion, and Mallory-Weiss syndrome in patients with advanced alcoholic liver disease or cirrhosis

AIM: To systematically review the data on distinctive aspects of peptic ulcer disease (PUD), Dieulafoy’s lesion (DL), and Mallory-Weiss syndrome (MWS) in patients with advanced alcoholic liver disease (aALD), including alcoholic hepatitis or alcoholic cirrhosis.

METHODS: Computerized literature search performed via PubMed using the following medical subject heading terms and keywords: “alcoholic liver disease”, “alcoholic hepatitis”,“ alcoholic cirrhosis”, “cirrhosis”, “liver disease”, “upper gastrointestinal bleeding”, “non-variceal upper gastrointestinal bleeding”, “PUD”, ‘‘DL’’, ‘‘Mallory-Weiss tear”, and “MWS’’.

RESULTS: While the majority of acute gastrointestinal (GI) bleeding with aALD is related to portal hypertension, about 30%-40% of acute GI bleeding in patients with aALD is unrelated to portal hypertension. Such bleeding constitutes an important complication of aALD because of its frequency, severity, and associated mortality. Patients with cirrhosis have a markedly increased risk of PUD, which further increases with the progression of cirrhosis. Patients with cirrhosis or aALD and peptic ulcer bleeding (PUB) have worse clinical outcomes than other patients with PUB, including uncontrolled bleeding, rebleeding, and mortality. Alcohol consumption, nonsteroidal anti-inflammatory drug use, and portal hypertension may have a pathogenic role in the development of PUD in patients with aALD. Limited data suggest that Helicobacter pylori does not play a significant role in the pathogenesis of PUD in most cirrhotic patients. The frequency of bleeding from DL appears to be increased in patients with aALD. DL may be associated with an especially high mortality in these patients. MWS is strongly associated with heavy alcohol consumption from binge drinking or chronic alcoholism, and is associated with aALD. Patients with aALD have more severe MWS bleeding and are more likely to rebleed when compared to non-cirrhotics. Pre-endoscopic management of acute GI bleeding in patients with aALD unrelated to portal hypertension is similar to the management of aALD patients with GI bleeding from portal hypertension, because clinical distinction before endoscopy is difficult. Most patients require intensive care unit admission and attention to avoid over-transfusion, to correct electrolyte abnormalities and coagulopathies, and to administer antibiotic prophylaxis. Alcoholics should receive thiamine and be closely monitored for symptoms of alcohol withdrawal. Prompt endoscopy, after initial resuscitation, is essential to diagnose and appropriately treat these patients. Generally, the same endoscopic hemostatic techniques are used in patients bleeding from PUD, DL, or MWS in patients with aALD as in the general population.

CONCLUSION: Nonvariceal upper GI bleeding in patients with aALD has clinically important differences from that in the general population without aALD, including: more frequent and more severe bleeding from PUD, DL, or MWS.

Endoscopic haemostasis: an overview of procedures and clinical scenarios

Acute gastrointestinal bleeding is among the most urgent situations in daily gastroenterological practise. Endoscopy plays a key role in the diagnosis and treatment of such cases. Endoscopic haemostasis is probably the most important technical challenge that must be mastered by gastroenterologists. It is essential for both the management of acute gastrointestinal haemorrhage and the prevention of bleeding during high-risk endoscopic procedures. During the last decade, endoscopic haemostasis techniques and tools have grown in parallel with the number of devices available for endotherapy. Haemostatic powders, over-the-scope clips, haemostatic forceps, and other emerging technologies have changed daily practise and complement the standard available armamentarium (injectable, thermal, and mechanical therapy). Although there is a lack of strong evidence-based information on these procedures because of the difficulty in designing statistically powerful trials on this topic, physicians must be aware of all available devices to be able to choose the best haemostatic tool for the most effective procedure. We herein present an overview of procedures and clinical scenarios to optimise the management of gastrointestinal bleeding in daily practise.
