Successful treatment of a gastric Dieulafoy's lesion with a hemoclip in a newborn infant

Dieulafoy lesion in a two-year-old boy: a case report

BACKGROUND

Massive gastrointestinal bleeding in children, mostly caused by esophageal varices secondary to chronic liver disease, is uncommon. Dieulafoy lesion in the gastrointestinal tract is a rare but important cause of gastrointestinal bleeding; massive bleeding from this lesion can be fatal unless adequate treatment is promptly initiated. We report a case of gastric Dieulafoy lesion in a 2-year old successfully treated with endoscopic hemoclipping.

CASE PRESENTATION

A 2-year-old Japanese boy was admitted to our department with sudden massive hematemesis. He had no significant past medical illness, and he was well just before the episode of hematemesis. A clinical examination revealed anemia (hemoglobin, 8.0 g/dl). The rapidly progressive anemia associated with massive hematemesis indicated the presence of an active bleeding in his upper gastrointestinal tract. We performed emergency gastroscopy under general anesthesia. The gastroscopy revealed the presence of an abnormal visible vessel with an adherent clot on the lower body of his stomach. No mucosal abnormality surrounding the lesion was noted; the lesion was thus diagnosed as Dieulafoy lesion. One hemostatic clip was placed on the Dieulafoy lesion and excellent hemostasis was obtained. He recovered without blood transfusion and was discharged 4 days post-endoscopy. He has recovered well with no recurrence of hematemesis.

CONCLUSIONS

Dieulafoy lesion is rare cause of sudden massive gastrointestinal bleeding in children. Nevertheless, it should be considered a differential diagnosis, even in babies. With advances in gastrointestinal endoscopy, as both a diagnostic and therapeutic modality, laparotomy secondary to gastrointestinal bleeding from Dieulafoy lesion has decreased in pediatric cases. Our case report demonstrates the feasibility of endoscopic hemoclipping for gastric Dieulafoy lesion in a child.

Massive Gastric Hemorrhage due to Dieulafoy's Lesion in a Preterm Neonate: A Case Report and Literature Review of the Lesion in Neonates

Dieulafoy's lesion is an extremely rare cause of upper gastrointestinal bleeding in the neonatal age group. Till now, only 6 cases of Dieulafoy's lesion in neonatal period have been reported in the international literature. Herein, we report an extremely rare case of Dieulafoy's lesion in a preterm neonate.

New insights to occult gastrointestinal bleeding: From pathophysiology to therapeutics

Obscure gastrointestinal bleeding is still a clinical challenge for gastroenterologists. The recent development of novel technologies for the diagnosis and treatment of different bleeding causes has allowed a better management of patients, but it also determines the need of a deeper comprehension of pathophysiology and the analysis of local expertise in order to develop a rational management algorithm. Obscure gastrointestinal bleeding can be divided in occult, when a positive occult blood fecal test is the main manifestation, and overt, when external sings of bleeding are visible. In this paper we are going to focus on overt gastrointestinal bleeding, describing the physiopathology of the most usual causes, analyzing the diagnostic procedures available, from the most classical to the novel ones, and establishing a standard algorithm which can be adapted depending on the local expertise or availability. Finally, we will review the main therapeutic options for this complex and not so uncommon clinical problem.

Pyloric atresia associated with Dieulafoy lesion and gastric dysmotility in a neonate

In this case study, we report a male infant with pyloric atresia, extreme gastric distension, and a caliber-persistent gastric artery (Dieulafoy lesion) with massive gastric bleeding. After a transverse pyloroplasty and endoscopic hemoclip application to the caliber-persistent gastric artery, very slow gastric emptying developed, which required repeated surgical interventions. Gastroduodenostomy failed to promote gastric emptying. The intraoperative and postmortem histologic examinations of the gastric wall revealed a loss of interstitial cells of Cajal, which possibly explains the extreme motility disorder.

The use of endoclips in the treatment of nonvariceal gastrointestinal bleeding

Acute nonvariceal gastrointestinal bleeding is the most common emergency managed by endoscopists and the endoscopic therapy has generally been recommended as the first-line treatment. Traditionally, endoscopic treatment included injections of epinephrine and sclerosing solutions or the use of thermocoagulation. In the last decade with the introduction of hemoclips and band ligators, we have witnessed a significant improvement in the clinical outcome of nonvariceal gastrointestinal bleeding. Endoclipping is a safe and effective technique that contributes to hemostasis of bleeding lesions of the gastrointestinal tract.

Interventional upper endoscopy: the pediatric perspective

Pediatric endoscopy has evolved from a purely observational modality into one with the potential for many therapeutic applications. Common therapeutic uses of endoscopy in children now include treatment of variceal bleeds and foreign body retrieval and newer procedures such as endoluminal gastroplication and endoscopic pyloromyotomy. Continuing research in pediatric endoscopy will allow pediatric gastroenterologists to perfect existing interventional endoscopic techniques and to learn to perform new ones.
