Characterization of the syndrome of UGI bleeding from a Mallory-Weiss tear associated with transesophageal echocardiography.

AIM: To quantitatively describe the syndrome of Mallory-Weiss tears associated (MWa) with antecedent transesophageal echocardiography (TEE) as a distinct syndrome. METHODS: Cases of MWa were identified by comprehensive, computerized literature search via PubMed and review of textbooks and monographs on TEE and gastroenterology. Statistical comparison of 17 identified MWa cases versus previously published series of 73 cases of Mallory-Weiss tears unassociated with TEE (MWu) was performed. A new illustrative case is also currently reported. RESULTS: Comparison between these two groups revealed the following: MWa patients were significantly older (67.1 vs. 52.6 years, p = .0002, assuming equal variance), likely due to MWa patients having preexisting cardiovascular disease for which the TEE was indicated. The two groups had similar sex distributions (60 vs. 76% male, p = .32). MWa patients were significantly, more frequently anticoagulated at the time of bleeding (90.9 vs. 9.6%, p < .00001, OR = 94.3, 95%-OR CI: 9.56-2293), likely because of anticoagulation for underlying cardiac disease for which TEE was indicated. MWa patients tended to more frequently rebleed and more frequently require endoscopic therapy (both parameters: 4/17 vs. 8/73, p = .23) and tended to more frequently require surgery or angiography to control bleeding (3/17 vs. 3/73, p = .08). MWa patients had significantly higher mortality (23.5 vs. 2.7%, p = .01, OR = 10.9, 95%-OR CI 1.48-97.8), likely because of their older age, concomitant heart disease, and administered anticoagulation. A new case of MWa is reported with notable features that extend the clinical spectrum of this syndrome: (1) tear associated with hiatal hernia, (2) presentation with severe, fatal UGI bleeding, and (3) no anticoagulation during bleeding episode. CONCLUSIONS: Patients with MWa represent a distinct clinical subset from patients with MWu, with significantly older mean age, more frequent concomitant anticoagulation, and higher mortality. They also tend to have more severe bleeding. These characteristics are important in clinically managing this syndrome.

[Etiology and pathogenesis of Mallory-Weiss syndrome].

Treatment results of 405 patients with Mallory-Weiss syndrome, X-ray gastric investigation in patients with severe bloating reflex were analyzed. Experimental part of the study involved rats and pigs, modeling esophageal and gastric rupture. Cardioesophageal and gastric cardial rupture happen in case of simultaneous sudden intragastric and intraabdominal hypertension, following the rule of Laplace.

Endoscopic hemostasis with metallic hemoclips for iatrogenic Mallory-Weiss tear caused by endoscopic examination.

AIM: Applied endoscopic techniques including mucosal resection, sclerotherapy and endoscopic retrograde cholangiopancreatography (ERCP) have been advanced and iatrogenic complications including Mallory-Weiss tear (MWT) occasionally occur in daily endoscopic procedures. The present study aimed to examine the advantages of clipping for MWT complications that occur during endoscopic examination. METHODS: Over 10 years, we experienced 47 patients with bleeding caused by MWT. Metallic hemoclips were applied for 38 patients for hemostasis. These patients were categorized into two groups: 18 patients in group A whose bleeding tear occurred during endoscopic examination in an iatrogenic condition, and 20 patients in group B visited the emergency unit due to other etiology of MWT. RESULTS: The background characteristics, including length of tears, were not different between the two groups. Initial hemostasis was 100% in groups A and B. Rebleeding was 0/18 (0%) in group A and 1/20 (5 %) in group B. Number of patients who received blood transfusion was significantly higher in group B (group A: 0/18, group B: 4/20). Hemoglobin level before hemostasis was 12.5 g/dL in group A which was not different to that in group B, 10.9 g/dL. CONCLUSION: Application of hemoclips was effective for bleeding MWT during endoscopic procedures, which warranted prophylactic application of hemoclips on MWT during endoscopic examination.

Risk factors for Mallory-Weiss Tear during endoscopic submucosal dissection of superficial esophageal neoplasms.

BACKGROUND: Adverse events during endoscopic submucosal dissection (ESD) of superficial esophageal neoplasms, such as perforation and bleeding, have been well-documented. However, the Mallory-Weiss Tear (MWT) during esophageal ESD remains under investigation. AIM: To investigate the incidence and risk factors of the MWT during esophageal ESD. METHODS: From June 2014 to July 2017, patients with superficial esophageal neoplasms who received ESD in our institution were retrospectively analyzed. The clinicopathological characteristics of the patients were collected. Patients were divided into an MWT group and non-MWT group based on whether MWT occurred during ESD. The incidence of MWTs was determined, and the risk factors for MWT were then further explored. RESULTS: A total of 337 patients with 373 lesions treated by ESD were analyzed. Twenty patients developed MWTs during ESD (5.4%). Multivariate analysis identified that female sex (OR = 5.36, 95%CI: 1.47-19.50, P = 0.011) and procedure time longer than 88.5 min (OR = 3.953, 95%CI: 1.497-10.417, P = 0.005) were independent risk factors for an MWT during ESD. The cutoff value of the procedure time for an MWT was 88.5 min (sensitivity, 65.0%; specificity, 70.8%). Seven of the MWT patients received endoscopic hemostasis. All patients recovered satisfactorily without surgery for the laceration. CONCLUSION: The incidence of MWTs during esophageal ESD was much higher than expected. Although most cases have a benign course, fatal conditions may occur. We recommend inspection of the stomach during and after the ESD procedure for timely management in cases of bleeding MWTs or even perforation outside of the procedure region.

[Mallory-Weiss syndrome after the use of biliary prosthesis]. / Zespól Mallory-Weiss po zastosowaniu protezy dróg zólciowych.

The Mallory-Weiss Syndrome is a rare complication of endoscopic examination. Upper gastrointestinal bleeding due to the Mallory-Weiss Syndrome usually stops spontaneously. The gastroscopy is an effective procedure (method) of diagnosis and treatment of the syndrome. Presented in this paper is a case of 49-year old woman with an upper gastrointestinal bleeding due to the Mallory-Weiss after biliary prosthesis removal. The choledocholithiasis was the primary reason for the initial insertion of prostheses. The cause of gastrointestinal bleeding was determined on the basis of performed gastroscopy in the early stage of prostheses removal forced by bleeding. The bleeding was effectively stopped with endoclips.

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.

[A rare complication of ERCP: Mallory-Weiss syndrome]. / Una rara complicanza dell'ERCP: la sindrome di Mallory-Weiss.

OBJECTIVE: To describe the management and outcome after endoscopic treatment of hematemesis by Mallory-Weiss Syndrome (MWS) occurred after CPRE (suspected choledocolithiasis). BACKGROUND DATA: Although cough and retching is common during EGD or CPRE, MWS resulting from endoscopy seems to be uncommon (0.0001-0.04%) and always self-limiting. CASE REPORT: The patient was submitted to CPRE with the suspicion of choledocholithiasis. Eight hours after CPRE the patient presented with hematemesis and hypotension. With emergency EGD, the AA identified a small bleeding mucosal tear (visible vessel with spurting) just proximal to the esophagogastric junction. The patient was safely treated with endoscopic hemoclipping after the failure of sclerotherapy. CONCLUSIONS: The usefulness of hemoclipping in MWS is emphasized: although always self-limiting, endoscopic hemostasis is mandatory in high risk patients. The hemoclips are effective and safe in hemostasis in the case of bleeding visible vessel (spurting or oozing), even with or after sclerotherapy. The hemoclips not obstacles the healing.

Asymptomatic Free Air Caused by Mallory-Weiss Tears during Endoscopy.

An 80-year-old woman was referred to our hospital for the treatment of advanced gastric cancer which extended from the antrum to the bulbus of the duodenum. Although the patient did not struggle or retch during endoscopy, multiple mucosal lacerations were observed in the proximal stomach by Mallory-Weiss tears. No evidence of perforation was identified at the sites. The day after endoscopy, computed tomography revealed free air close to the gastric cardia, but the patient did not complain of any symptoms; she was able to consume a normal diet and did not require any treatment.

The spectrum of the Mallory-Weiss tear.

A Mallory-Weiss tear is a mucosal laceration occurrring at or near the esophagogastric junction and is most often associated with vomiting. This is a common cause of upper gastrointestinal bleeding; in our series, 14% of patients presenting to the hospital because of upper gastrointestinal bleeding had Mallory-Weiss tears. Massive hemorrhage is not characteristic and 37% of the patients required no blood transufsions. A classical history of nonbloody emesis followed by hematemesis was found in only 29% of patients. The most common story was the appearance of blood with the first vomiting. In 35% of our patients with Mallory-Weiss tear, an additional potential bleeding site was identified, and, in approximately half of these patients, it was actually bleeding. Most Mallory-Weiss tears stop bleeding spontaneously and supportive treatment is all that is required. If bleeding continues, infusion of vasoactive substances into the celiac artery or into the left gastric artery often obviates the need for operation.

The role of endoscopy in early postoperative haemorrhage.

Diagnostic as well as therapeutic endoscopy has a decisive role in management of early postoperative haemorrhage. Endoscopy combines easy access to the upper and lower gastrointestinal tract and application of an array of interventional tools. In near future, even the small bowel will be accessible for diagnostic and therapeutic measures due to the advent of double-balloon enteroscopy. Thus, the endoscopist increasingly replaces the surgeon for diagnosis and therapy of postsurgical bleeding. Published data on frequency and aetiology of postoperative haemorrhage are scarce and mainly casuistic. Sources of gastrointestinal bleeding associated with surgery may be: anastomotic ulcers, mucosal ischaemia, 'stress' ulcers, reflux-induced lesions, coagulopathies (e.g. in sepsis or after organ transplantation) and aortoenteric fistula after bypass surgery. The endoscopist will frequently identify the culprit lesion and guide further management of the patient (e.g. endoscopic approach, repeated surgery, interventional radiology). All accessible lesions in postoperative haemorrhage should primarily be treated by endoscopic means, except aortoenteric fistulas. There is even a place for repeated endoscopy in recurrent bleeding. In the face of lacking controlled data, the endoscopist often has to rely on his personal experience in the selection of therapeutic options.

Postemetic hematomas: a variant of the Mallory-Weiss syndrome.

Of forty-four patients with the Mallory-Weiss syndrome, nine (20 per cent) had endoscopic evidence of small submucosal hematoma(s) lying in or adjacent to the region of the the tear. These small hematomas are believed to occur most commonly as a variant of the Mallory-Weiss lesion.

Mallory-Weiss syndrome: possible link to water immersion and subsequent air flight.

Mallory-Weiss Syndrome (MWS) lesions account for up to 15 per cent of upper gastrointestinal bleeding episodes. Typically these lesions present as a consequence of vomiting that is often associated with alcoholism. Recently other conditions such as pregnancy, migraine, hiatal hernia, gastric ulcer, biliary disease, and various medications have been associated with MWS. We report on a 32-year-old male who developed a MSW lesion after a prolonged period of swimming followed by an extended commercial airplane flight. The hemodynamic changes associated with swimming (increased central distribution of blood volume) and the pressure changes in commercial aircraft (a reduction of 0.3 atmospheres of pressure) are discussed. We conclude that the combination of these factors contributed to the development of a MWS lesion and gastrointestinal bleeding in this patient. We recommend that both air travel and athletic activities be considered as possible contributing factors in the evaluation of the cause of new-onset gastrointestinal bleeding.

Retrospective analysis of iatrogenic Mallory-Weiss tears occurring during upper gastrointestinal endoscopy.

BACKGROUND/AIMS: This study was made to determine the incidence and natural history of iatrogenic Mallory-Weiss tears. PATIENTS AND METHODS: We retrospectively analyzed twelve cases of iatrogenic Mallory-Weiss tears identified from 2,461 consecutive upper gastrointestinal endoscopies performed at our institution over a period of twenty-two months. RESULTS: In all cases, bleeding stopped spontaneously without the need of blood transfusions, endoscopic hemostasis therapy or any other interventions. Eight patients (67%) had retching or struggling during the procedure. Hiatus hernias were noted in three patients (25%). CONCLUSIONS: Iatrogenic Mallory-Weiss tears are rare and generally have a benign course. They tend to occur mostly in patients who have experienced excessive retching or struggling during endoscopy.

Mallory-Weiss syndrome. Experience in a community hospital.

The Mallory-Weiss syndrome is characterized by repeated bouts of retching and/or vomiting followed by the sudden onset of hematemesis or melena. Bleeding arises from linear, nonperforating mucosal lacerations at the cardia, cardioesophageal junction, distal esophagus, or a combination of these sites. Hiatal hernia is often a coexisting finding. Severity of hemorrhage can vary from mild to severe (100 to 2,000 ml). The clinical course is usually benign. The diagnosis can be suspected from the history and confirmed by upper gastrointestinal endoscopy. In the majority of patients, medical management controls the bleeding. About 10% to 20% of unselected patients require surgical intervention. With the proper, prompt use of fiberoptic endoscopy in the diagnosis of upper gastrointestinal hemorrhage has come an increase in the number of cases of Mallory-Weiss syndrome being identified. This is true even in community hospitals. The result has been a decrease in surgical intervention and overall mortality.

Hematemesis and melena: Mallory-Weiss syndrome.

The records of 29 patients with Mallory-Weiss tears diagnosed by endoscopy are reviewed. Ingestion of alcohol was a chief cause of bleeding. Single tears were the largest in number and 68% of the lacerations were seen just distal to the esophago-cardial junction. Lacerations occurred more frequently on the right lateral wall of cardia than on the left lateral wall. Most of these lesions were mild and could be treated medically except for two cases which were surgically treated.

[Mallory-Weiss syndrome. Surgical treatment after sclerotherapy. Presentation of a case and review of the literature]. / Síndrome de Mallory-Weiss. Tratamiento quirúrgico después de escleroterapia. Presentación de un caso y revisión de la literatura.

We herein report a case of a male patient aged 23, with acute upper gastrointestinal hemorrhage, secondary to ingestion of acetyl salicylic acid. Endoscopy showed a linear laceration in the esophagus-gastric union. Based on endoscopic findings the diagnosis of Mallory-Weiss Syndrome was established. Surgical treatment was required, after sclerotherapy; we reviewed the literature for presenting a general panorama of this pathology.

[Clinical study of Mallory-Weiss syndrome in the aged patients over 75 year--mainly five cases induced by the endoscopic examination].

Cases of Mallory-Weiss syndrome aged over 75 year were analyzed with regard to their clinical features. In a 5-year period, there were 9 such cases, representing 19% of the total number of Mallory-Weiss syndrome cases. Four patients had a history of retching or vomiting, but in the other 5 patients, Mallory-Weiss tears occurred during endoscopic examination with slight vomiting reflex or even almost vomiting reflex. The latter cases had a spindle-shaped tear which was located on the lesser curvature at the cardia of the stomach. All patients were managed conservatively by observation without endoscopic hemostatic procedure, because the amount of bleeding was small. The 5 patients were thin and three of them had chronic atrophic gastritis. Mucosal weakness is an important etiologic factor in aged patients who develop Mallory-Weiss syndrome.

Gastro-esophageal barotrauma in diving: similarities with Mallory-Weiss syndrome.

Mallory-Weiss syndrome (MWS) is a well-defined entity in clinical medicine. However, the development of such a syndrome as a result of overpressure barotrauma of the stomach after repeated shallow-water scuba dives is rare. Also rare is the delayed onset of the MWS, approximately 20 hours after the dives. The causes of development of MWS in connection with scuba diving are discussed. The main causes seem to be the repeated changes of gas volume in the stomach with subsequent pressure forces toward the cardia in the course of repeated dives. The possibility of serious diving accident due to overpressure barotrauma of gastro-intestinal system is also pointed out.

[Clinico-morphological parallels in Mallory-Weiss syndrome]. / Kliniko-morfologicheskie paralleli pri sindrome Mallori-Veissa.

The article deals with the results of treatment of 180 patients with the Mallory-Weiss syndrome. Morphological studies of the gastric wall was conducted in 16 patients who underwent operation. It was established that developmental anomalies, chronic gastritis, and pathological changes of the vessels of the lamina muscularis mucosae impairing its mobility and strength may be the morphological substrate which precedes the development of the Mallory-Weiss syndrome.

The authors have analyzed 25 observations of patients with the Mallory-Weiss syndrome which made up 3,04% of all the patients with gastroduodenal bleedings. The authors emphasize the role of the endoscopic method for examining the patients to diagnose this pathology. The most rational method is believed to be the conservative treatment. When it fails the surgery should be organ-preserving. Twenty four patients were treated conservatively, one patient was subjected to gastrotomy and suturing of the mucosa fissure. All the patients recovered.
