Dieulafoy's lesion of the upper GI tract: a comprehensive nationwide database analysis

A diagnostic dilemma: a case report of concomitant duodenal Dieulafoy lesion and gastric ulcer

Dieulafoy lesions (DL) are an uncommon cause of gastrointestinal bleeding which is often difficult to diagnose due to the rarity of the condition and varying clinical presentations. This case describes an unusual presentation of upper gastrointestinal bleeding in an 85-year-old female with findings on two separate gastroscopies of both a gastric ulcer and duodenal DL. The pathophysiology of DL remains poorly understood and despite shared risk factors, these two pathologies are rarely reported concurrently. The presence of a concomitant gastric ulcer further complicated the diagnosis and treatment of the duodenal DL in this case. This highlights the importance of clinician awareness of this pathology and its presentation and the need for early repeat endoscopy.

Sustained Hemostasis With the Padlock™ Over-the-scope Clip for Gastric Fundus Dieulafoy's Lesion in the Setting of Anticoagulation Following Hemorrhagic Shock From Two Dieulafoy's Lesions

Dieulafoy's lesions (DLs) are a rare and difficult-to-identify cause of acute gastrointestinal bleeding that can lead to hemorrhagic shock. We present a case of a 23-year-old previously healthy male presenting with melenic stools and hemorrhagic shock. Computed tomography of abdomen and pelvis with oral and intravenous contrast showed a possible source of hemorrhage as a hyperdense intraluminal material within the stomach. Initial urgent esophagogastroduodenoscopy showed a large, nonbleeding distal esophageal DL, which was treated successfully with 10 mL of 1:10,000 epinephrine and bipolar cauterization with 10 Fr Gold Probe™. Hemorrhage recurred 2 d later, prompting another esophagogastroduodenoscopy, which found another DL within the gastric fundus. Treatment with epinephrine, Gold Probe™, and through-the-scope Hemoclips was unsuccessful because of difficult visualization and positioning. A subsequent attempt was made using the over-the-scope clip (OTSC) Padlock™ Clip Defect Closure System with successful hemostasis and stabilization of the patient. His hospital course was complicated by left lower lobe segmental pulmonary embolism without right heart strain for which he was discharged on 3 months of anticoagulation with apixaban. On follow-up, there was no recurrence of gastrointestinal bleeding (GIB) despite 3 months of anticoagulation. He did not complete the Basic Underwater Demolition/SEAL (BUD/S) Training. This case report demonstrates the evaluation and management of a patient with hemorrhagic shock from two DLs and sustained hemostasis with the Padlock™ OTSC in the setting of apixaban anticoagulation.

Over-the-Scope Clip Applications as First-Line Therapy in the Treatment of Upper Non-variceal Gastrointestinal Bleeding, Perforations, and Fistulas

Background

The over-the-scope clip (OTSC) is an innovative device and has been successfully used in endoscopic treatment, however, there is a lack of clinical data from China. The aim of this study is to investigate the OTSC applications in the treatment of upper non-variceal gastrointestinal bleeding (UNVGIB), perforations, and fistulas in China.

Methods

In total, 80 patients were treated with one OTSC respectively as first-line therapy in our endoscopy center between January 2016 and November 2020. Among them, 41 patients had UNVGIB, 34 patients had perforations, and five patients had fistulas. The technical and clinical success rates were used to assess the efficacy of OTSC on the above diseases. In addition, we compared the hemostatic efficacy of OTSC with the standard endoscopic therapy in ulcer bleeding and Dieulafoy's lesion by propensity score matching analysis.

Results

In general, the OTSCs were applied successfully in all patients and achieved 100% (80/80) technical success. The clinical success of all patients was 91.3% (73/80). Among 41 patients with UNVGIB, the clinical success was 85.4% (35/41); 6 patients presented with recurrence. For patients of Dieulafoy's lesion and under antithrombotic therapy, we found that OTSC treatment had both efficient and reliable hemostasis effects. In addition, according to the characteristics of ulcers, site of bleeding lesion, and Blatchford score, all patients received similar and reliable clinical success rates. After propensity score matching, we found that OTSC treatment had low rebleeding rates when compared with standard endoscopic therapy in both Dieulafoy's lesion (15.0 vs 30.0%) and ulcer bleeding (17.6 vs 29.4%). Among 34 patients with perforations, the clinical success was 100% (34/34). Among five patients with fistulas, only one patient failed in maintaining the OTSC before esophageal fistula healing, and the clip achieved an overall clinical success of 80% (4/5).

Conclusion

The OTSC represents a safe and effective endoscopic therapy for UNVGIB, perforations, and fistulas as first-line treatment, especially for Dieulafoy's lesion or patients under antithrombotic therapy for UNVGIB, etc. However, OTSC application in these specific lesions or patients lacks adequate evidence as first-line treatment. Therefore, further larger sample and multi-center clinical trials are required to improve its indications in clinical treatment.
