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.

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.

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.

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.

Upper gastrointestinal bleeding.

Upper gastrointestinal (GI) bleeding remains a commonly encountered diagnosis for acute care surgeons. Initial stabilization and resuscitation of patients is imperative. Stable patients can have initiation of medical therapy and localization of the bleeding, whereas persistently unstable patients require emergent endoscopic or operative intervention. Minimally invasive techniques have surpassed surgery as the treatment of choice for most upper GI bleeding.

A case of Sengstaken-Blakemore tube-induced esophageal rupture repaired by endoscopic clipping.

A 57-year-old man was admitted to another hospital for hematemesis due to heavy drinking. A Sengstaken-Blakemore tube was inserted and the patient was transferred to our hospital. The patient's ensuing movements inadvertently caused an esophageal rupture 2.5 cm in size. Since the patient's condition was stable, treatment via endoscopic repair using metallic clips was chosen over emergency surgery. Two hemoclips were fixed at the ends of the ruptured area; by employing an endoscopic detachable snare, the ruptured area was carefully repaired with 10 metallic clips. As a result, the esophageal rupture could be successfully repaired by endoscopic procedure rather than performing surgery.

[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.

[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.

[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.

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.
