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.
Insights
Mallory-Weiss Tears (MWT) occurred in 5.4% of patients undergoing esophageal endoscopic submucosal dissection (ESD). Female sex and longer procedure times are key risk factors for MWT during ESD.
Area of Science:
- Gastroenterology
- Gastrointestinal Endoscopy
- Surgical Complications
Background:
- Adverse events like perforation and bleeding are known complications of endoscopic submucosal dissection (ESD) for superficial esophageal neoplasms.
- The occurrence and risk factors of Mallory-Weiss Tears (MWTs) during esophageal ESD are not well-established.
Purpose of the Study:
- To determine the incidence of MWTs during esophageal ESD.
- To identify clinicopathological risk factors associated with MWT development during esophageal ESD.
Main Methods:
- Retrospective analysis of 337 patients with superficial esophageal neoplasms who underwent ESD between June 2014 and July 2017.
- Patients were categorized into MWT and non-MWT groups to compare incidence and explore risk factors.
- Multivariate analysis was employed to identify independent risk factors for MWT.
Main Results:
- The incidence of MWTs during esophageal ESD was 5.4% (20 out of 337 patients).
- Independent risk factors for MWT included female sex (OR=5.36) and procedure time exceeding 88.5 minutes (OR=3.95).
- Most MWTs were managed conservatively with endoscopic hemostasis, and all patients recovered without surgery.
Conclusions:
- The incidence of MWTs during esophageal ESD is higher than previously thought.
- While typically benign, MWTs can lead to severe complications, necessitating careful monitoring.
- Routine inspection of the stomach during and after ESD is recommended for early detection and management of MWTs.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
