Mallory-Weiss tear complicating upper endoscopy: Case reports and review of the literature

Endoscopic Hemostasis With Metallic Hemoclips for Iatrogenic Mallory‐weiss Tear Caused by Endoscopic Examination

“…During the past 20 years, it has been reported that 5–15% of upper gastrointestinal bleeding is caused by MWT 2–5 . Watts reported a case of MWT that occurred during endoscopic examination, 6 and MWT has been recognized to be one of the complications related to endoscopic examination 6–10 . The incidence of iatrogenic complications, including MWT, has increased with advances in and the increased use of endoscopic examination; the complication rate of MWT was reported to be 0.07–0.49% 8,9 .…”

“…[2][3][4][5] Watts reported a case of MWT that occurred during endoscopic examination, 6 and MWT has been recognized to be one of the complications related to endoscopic examination. [6][7][8][9][10] The incidence of iatrogenic complications, including MWT, has increased with advances in and the increased use of endoscopic examination; the complication rate of MWT was reported to be 0.07-0.49%. 8,9 Most patients with MWT do not require endoscopic hemostasis and blood transfusion, [2][3][4][5] but several reports have indicated that patients with wide tears on the gastroesophageal mucosa suffered from massive bleeding and required endoscopic hemostasis.…”

Mallory-Weiss Tear during Esophagogastroduodenoscopy

“…Hiatal hernia has been found in 40–100% of patients with MWT [ 12 ]. The greatest pressure difference develops in the hernia pouch compared with the rest of the stomach during retching or vomiting, thereby increasing the potential for mucosal laceration [ 13 ]. In addition, atrophic gastritis has also been shown in more than half of patients with MWT after autopsy.…”
