Endoscopic Hemoclipping Treatment for Gastric Dieulafoy Lesion in a Newborn / 대한소아소화기영양학회지

Dieulafoy's lesion is defined as a small mucosal defect overlying an abnormal, large caliber submucosal artery that protrudes through the gastrointestinal mucosa. This lesion is a rare cause of massive upper gastrointestinal bleeding in the pediatric population and extremely rare in neonates. We report a 1-day-old neonate who presented with massive gastrointestinal bleeding caused by a gastric Dieulafoy lesion, which was successfully treated by endoscopic hemoclipping without any complications.

A Case of Transparent Cap-fitted Endoscopic Hemoclipping on a Bleeding Dieulafoy's Lesion in the Ampulla of Vater / 대한소화기내시경학회지

Dieulafoy's lesion is a rare cause of repetitive and massive gastrointestinal bleeding, and this is characterized by an isolated arteriole protruding through a small mucosal defect. Dieulafoy's lesion is generally found in the stomach within 6 cm of the gastroesophageal junction, and usually on the lesser curvature, but many lesions have been reported in extragastric locations, including the esophagus, small bowel and rectum. A Dieulafoy's lesion in the ampulla of Vater is extremely rare, and only one such case has been reported in the Korean population. We experienced a rare case of Dieulafoy's lesion in the ampulla of Vater with massive pulsatile bleeding, and this was successfully treated by transparent cap-assisted endoscopic hemoclipping. We report here on this case with a review of the relevant literature.

An Incidental Asymptomatic Dieulafoy's Lesion in the Colon: A Case Report

A Dieulafoy's lesion is an uncommon, but important, cause of gastrointestinal bleeding. It is associated with massive, life-threatening hemorrhage and is typically difficult to diagnose. Although originally described in the stomach and rarely found below the proximal stomach, identical lesions have been reported in other gastrointestinal organs, including the duodenum, jejunum, colon, and rectum. Most cases occur with bleeding in the gastrointestinal tract. However, we present an incidental asymptomatic Dieulafoy's lesion in the colon, which was treated successfully by using an endoscopic hemoclipping technique.

Predictors of Rebleeding after Hemoclip Therapy for Treating High-risk Bleeding Ulcers: Hemoclip Therapy Alone was Comparable to Combination Treatment with Epinephrine Injection / 대한소화기내시경학회지

BACKGROUND/AIMS: Active bleeding and non-bleeding visible vessels in patients with bleeding peptic ulcer are associated with a high risk of rebleeding. The aim of our study was to define the risk factors associated with failure of endoscopic hemostasis and rebleeding in patients with active peptic ulcer bleeding. METHODS: We retrospectively reviewed 119 patients (90 men and 29 women; mean age, 60.14+/-14.67 years) with active peptic ulcer bleeding (spurting, oozing and/or non-bleeding visible vessel) and who were treated in Wonkwang Medical Center from January 2002 to January 2007. They were classified to endoscopic hemoclipping alone group (n=75) or endoscopic hemoclipping combined with epinephrine injection group (n=44), according to the therapeutic modality. RESULTS: Initial hemostasis was achieved in the two groups (100%), and permanent hemostasis was achieved 71.4% in all the patients. Operation was done in eight patients (6.7%), and six patients (5%) in the two groups, respectively, died within 1 month after initial hemostasis because of bleeding related complications. Recurrent bleeding, the duration of the hospital stay, blood transfusion requirements, complications and the operation and mortality rates were not statistically different between the hemoclip alone and combination groups. Univariate analysis showed that rebleeding was related to the presence of shock on admission (p=0.01), complication (p=0.00), the pulse rate (<100/min) on admission (p=0.04), single ulcer (p=0.032), the level of hemoglobin (<8 g/dL) (p=0.02) and the volume of transfusion (<3 units) after the procedure (p=0.005) in all the patients. On the multivariate analysis that was adjusted for age and gender, the hemoglobin level (<8 g/dL) (odds ratio = 10.5) was the only significant predictor for early rebleeding. CONCLUSIONS: This result may suggest that the combination method does not provide a substantial advantage over hemoclipping alone for the hemostatic management of active peptic ulcers bleeding. A low hemoglobin level on admission may be useful to predict rebleeding after initial endoscopic hemostasis in patients with active peptic ulcer. However, this study was designed retrospectively, so the comparison between these two groups should be re-evaluated prospectively in a large, multicenter trial.

Endoscopic Resection of a Large Colonic Lipoma / 대한소화기내시경학회지

Although colonic lipomas constitute the most common nonepithelial neoplasms of the gastrointestinal tract, colonic lipomas are rare benign tumors. Most colonic lipomas are asymptomatic and are incidentally identified at the time of endoscopy or surgery. Lipomas may cause symptoms such as bleeding, obstruction or intussusception when the size of a tumor exceeds 2 cm. Surgical resection is recommended for larger lipomas to relieve symptoms or exclude a malignancy. There are few published reports on the endoscopic removal of colonic lipomas. Endoscopic snare polypectomy has been used to treat clinically symptomatic colonic lipomas. However, removal of lipomas 2 cm or greater in diameter has been associated with a greater risk of perforation. Using a detachable snare or hemoclipping may reduce the risk of complications after a polypectomy. We report a case of a large colonic lipoma that was treated with endoscopic polypectomy using a detachable snare and hemoclipping.

A Case of a Bleeding Dieulafoy's Lesion in a Duodenal Diverticulum Treated by Endoscopic Hemoclipping / 대한소화기내시경학회지

A duodenal diverticulum is common and usually originates in the second portion of the duodenum. The majority of diverticula are asymptomatic; however, they may sometimes present with symptoms such as obstruction, hemorrhage, perforation, jaundice and pancreatitis. Active bleeding from a duodenal diverticulum is rare, and moreover, Dieulafoy's lesion as a cause is quite rare with very few cases reported so far. The use of endoscopic methods instead of surgery in achieving hemostasis has been on the increase with the widespread use and improvement in endoscope instrumentation and accessories. Of these methods, the use of endoscopic hemoclipping for Dieulafoy's lesion is considered more effective and safe than the use of other methods, such as injection and thermal methods. We report here a case of a bleeding Dieulafoy's lesion in a duodenal diverticulum treated by endoscopic hemoclipping.

A Case of Endoscopic Hemoclip Management of Dieulafoy-like Lesion on the Hyperplastic Polyp in the Duodenum / 대한소화기내시경학회지

Dieulafoy's lesion (DL) is an uncommon but important cause of massive upper gastrointestinal bleeding that has been reported to be involved in 0.3~6.7% of cases of major gastrointestinal bleeding. The lesion usually occurs in the lesser curvature of the stomach within 6 cm of the gastroesophageal junction. Similar lesions have also been observed in the esophagus, duodenum, small intestine, colon, and rectum. Most DLs encountered in the duodenum occur in the bulb. Recently, with the advances in endoscopic techniques, the successful management of DL has been achieved through the application of a hemoclip or elastic band ligation. In particular, the application of a hemoclip is considered to be a safe and effective treatment for DL located on a relatively narrow and thin walled canal such as the duodenum. We report the successful application of endoscopic hemoclipping for the treatment of a rare Dieulafoy-like lesion on a hyperplastic polyp in the 2nd portion of the duodenum.

Clinical Usefulness of Proton Pump Inhibitor Intravenous Treatment in Bleeding Peptic Ulcer / 대한소화기내시경학회지

BACKGROUND/AIMS: Recently, high dose PPI intravenous (IV) infusion after endoscopic hemostasis was found to decrease the recurrent bleeding rate. Therefore, we conducted this study to define the effect of endoscopic hemoclipping with PPI IV infusion on the recurrent bleeding rate. METHODS: We conducted a double-blinded prospective randomized control study. A total of 35 patients were endoscopically diagnosed with bleeding peptic ulcer of Forrest classification Ia, Ib, IIa between Jan. 2003 and Sep. 2003 in our hospital. We carried out epinephrine injection therapy around the ulcer, followed by hemoclipping at the exposed vessel. After controlling for endoscopic bleeding, we randomly divided the patients into two groups. One group received a PPI IV infusion (pantoprazole 80 mg/day) and the other group received a placebo for three days. RESULTS: Only one PPI IV-infused patient and one patient receiving placebo showed recurrent bleeding at two days after endoscopic therapy. The PPI IV infusion group showed 100% (17/17) initial hemostatic rate, 5.8% (1/17) recurrent bleeding rate within 3 days, 0% (0/17) recurrent bleeding rate after 3 days, and 0% (0/17) complication rate. For these same values, the placebo group showed 100% (18/18), 5.5% (1/18), 0% (0/18), and 0% (0/18), respectively. CONCLUSIONS: PPI IV infusion showed no addictive hemostatic effect. We think hemoclipping is a very effective hemostatic method, and PPI IV infusion may not be required after appropriate endoscopic management

Appendiceal Stump Bleeding That was Treated by Endoscopic Hemoclipping / 대한소화기내시경학회지

Appendiceal stump bleeding is a rare, but occasionally life-threatening complication. Significant lower gastrointestinal hemorrhage from an ulcerated appendiceal stump may occur after uncomplicated appendectomy. The common management includes ligation of the bleeding vessel or cecal resection by either emergency laparotomy or laparoscopy. Angiographic embolization of the bleeding vessel is an alternative therapeutic option. We report here on a case of gastrointestinal hemorrhage from an appendiceal stump, and this occurred six days after appendectomy. The bleeding was controlled endoscopically by placing hemoclips on the distinct vessel. The patient recovered thereafter without further intervention. Endoscopic hemoclipping is an effective and safe procedure, and it can replace emergency laparotomy, laparoscopy or angiographic embolization for treating appendiceal stump bleeding.

A Case of Lower Gastrointestinal Bleeding due to Angiodysplasia in the Terminal Ileum / 대한소화기내시경학회지

Angiodysplasia has been recognized as an important cause of lower gastrointestinal bleeding, but it is difficult to confirm the lesions. Angiodysplasia in the small bowel could be the most probable cause of bleeding particularly in the elderly patients when usual methods fail to document the focus. Small bowel angiodysplasias have been diagnosed by angiography and/or surgery at the sites where usual endoscope could not reach, and treated by medical therapy, angiographic embolization or surgery. We experienced a case of a bleeding angiodysplasia in the terminal ileum in a 51-year-old man who was taking anti-platelet agents. The lesion was diagnosed by colonoscopy, and bleeding was easily controlled with hemoclipping.

A Case of Dieulafoy's Lesion in Duodenal Bulb / 소아과

Dieulafoy's lesion is an uncommon cause of recurrent massive gastrointestinal bleeding resulting from an abnormally large submucosal artery that protrudes through a small mucosal defect. Incidence of Dieulafoy's lesion as a source of upper gastrointestinal bleeding ranges from 0.3 to 6.7% in adults. But recently, the incidence is on an increasing trend by advanced endoscopic diagnostic technique. Lesions may occur anywhere in the gastrointestinal tract but are typically located within 6 to 10 cm of the gastroesophageal junction, generally along the lesser curvature of the stomach. Lesions are life threatening because bleeding is often massive and recurrent. The mean age of presentation is in the fifth decade and patients of pediatric age are extremely rare. We report a 12-year-old male patient who had Dieulafoy's lesion, diagnosed by emergency gastrointestinal endoscopy. Endoscopic finding was active bleeding from Dieulafoy's lesion in the duodenal second portion. Bleeding was controlled with endoscopic hemoclipping without complication or recurrence.

Angiodysplasia in a Child with Chronic Renal Failure: Endoscopic Hemostatic Therapy / 대한소아소화기영양학회지

Angiodysplasia is the most common vascular abnormality of the gastrointestinal tract and probably the most frequent cause of recurrent lower intestinal bleeding in otherwise healthy elderly patients. Also, it is an important cause of hemorrhage in chronic renal failure observed in up to 19~32% of patients. Bleeding due to gastric angiodysplasia is treated by various endoscopic approaches, including argon and Nd:YAG laser photocoagulation, monopolar or bipolar electrocoagulation, heater probe, injection sclerotherapy, band ligation or hemoclipping. A 15-year-old boy, who had undergone hemodialysis for chronic renal failure for about 10 years, was admitted due to melena and progressive anemia. A gastroduodenoscopy revealed a cherry red and fern-like lesion with oozing on the posterior wall at junction of gastric body and fundus. Endoscopic hemoclipping therapy was performed. However, melena recurred four days later. Argon plasma coagulation and hemoclipping therapy were performed again. Since then, no recurrence of bleeding has been observed.

Endoscopic Hemoclipping in a Terminal Ileal Dieulafoy's Lesion / 대한소화기내시경학회지

Dieulafoy's lesion is an uncommon source of massive gastrointestinal hemorrhage. The lesion predominantly occurs in the proximal stomach, but may occur in all parts of the gastrointestinal tract including small bowel, colon and rectum. We herein report a case of a patient who presented with hematochezia from Dieulafoy's lesion of the terminal ileum with adherent blood clots. Bleeding was successfully controlled with endoscopic treatment by utilizing hemoclipping.

A Case of Endoscopic Treatment of Bleeding in Duodenal Dieulafoy's Lesion / 대한소화기내시경학회지

Dieulafoy's lesions are often unrecognized cause of obscure, massive gastrointestinal bleeding, reported to be 0.3~1.5% of cases of major gastrointestinal bleeding. It is characterized by severe bleeding from rupture of an exposed submucosal artery. Dieulafoy's lesion is usually occured in the lesser curvature of the stomach within 6 cm of the gastroesophageal junction. Similar lesions have also been described in the esophagus, duodenum, small intestine, colon, and rectum. The diagnosis is made by endoscopy, angiography, laparoscopy, or laparotomy. Endoscopy showed protruding and eroded artery with pulsatile bleeding or adherent thrombus. Currently, various therapeutic options are available to the endoscopist for the treatment of Dieulafoy's lesions. Therapeutic endoscopy should now become first-line therapy for Dieulafoy's lesions. We experienced a rare case of bleeding from the duodenal Dieulafoy's lesion. Endoscopic hemoclipping was performed successfully. We report this case with a review of the literature.
