- Photodynamic therapy, a curative local treatment for esophageal squamous cell carcinoma, involves a photosensitizing drug (photosensitizer) with affinity for tumors and a photodynamic reaction triggered by laser light. Previously, photodynamic therapy was used to treat superficial esophageal squamous cell carcinoma judged to be difficult to undergo endoscopic resection. Recently, photodynamic therapy has mainly been performed for local failure after chemoradiotherapy. Although surgery is the most promising treatment for local failure after chemoradiotherapy, its morbidity and mortality rates are high. Endoscopic resection is feasible for local failure after chemoradiotherapy but requires advanced skills, and its indication is limited to within the submucosal layer by depth. Photodynamic therapy is less invasive than surgery and has a wider indication than endoscopic resection. Porfimer sodium (a first-generation photosensitizer) causes a high frequency of side effects related to photosensitivity and requires the long-term sunshade period. Talaporfin (a second-generation photosensitizer) requires a much shorter sun-shade period than porfimer sodium. Photodynamic therapy will profoundly change treatment strategies for local failure after chemoradiotherapy.

- Background
/Aims: Endoscopic treatment (ET) has been applied for decades to treat subepithelial tumors, including gastrointestinal stromal tumors (GISTs). However, the efficacy of ET remains debatable. In this study, we evaluated the efficacy and safety of ET for GISTs in the upper gastrointestinal tract.
Methods
This retrospective single-center study included 97 patients who underwent ET. All patients were enrolled from July 2014 to July 2018. Parameters such as demographics, size, resection margin, complications, pathological features, procedure time, total cost, and follow-up were investigated and analyzed.
Results
Our study achieved 100% en bloc resection and 77.4% (72/93) R0 resection. The most common location was the fundus with a mean tumor size of 2.1±1.43 cm. The mean age, procedure time, hospital stay, and cost were 59.7±11.29 years, 64.7±35.23 minutes, 6.8 days, and 5,337 dollars, respectively. According to National Institutes of Health classification, 63 (64.9%), 26 (26.8%), 5 (5.2%), and 3 (3.1%) patients belonged to the very low, low, intermediate, and high risk classification, respectively. Immunohistochemistry results showed a 100% positive rate of CD34, DOG-1, CD117, and Ki67. A mean follow-up of 21.3±13.0 months showed no recurrence or metastasis.
Conclusions
ET is effective and safe for curative removal of GISTs in the upper gastrointestinal tract, and it can be a treatment of choice for patients with no metastasis.

- Background/Aims
The purpose of this study is to verify the risk factors associated with Dieulafoy lesion formation in the upper gastrointestinal tract.
MethodsA case-control study was performed by reviewing the electronic medical records of 42 patients who were admitted to a tertiary medical center in the Daejeon region for Dieulafoy lesions from September 2008 to October 2013, and the records of 132 patients who were admitted during the same period and who underwent endoscopic examination for reasons other than bleeding. We analyzed clinical and endoscopic findings retrospectively, and searched for risk factors associated with Dieulafoy lesion formation.
ResultsAll 42 patients diagnosed with Dieulafoy lesion had accompanying bleeding, and the location of the bleeding was proximal in 25 patients (59.5%), the middle portion in seven patients (16.7%), and distal in 10 patients (23.8%). Antiplatelet agents (p=0.022) and alcohol (p=0.001) use showed statistically significant differences between the two groups. The odds ratios (95% confidence intervals) of the two factors were 2.802 (1.263 to 6.217) and 3.938 (1.629 to 9.521), respectively.
ConclusionsThis study showed that antiplatelet agents and alcohol consumption were risk factors associated with Dieulafoy lesion formation in the upper gastrointestinal tract.

- Background/Aims
Argon plasma coagulation (APC) has some merits in the treatment of gastric neoplasms including a shorter operative time and fewer complications compared with endoscopic mucosal resection or endoscopic submucosal dissection. However, there are few reports on the outcomes of gastric neoplasms treated using APC. The aim of this study was to evaluate APC in the treatment of early gastric neoplasms in terms of clinical efficacy, safety, and local recurrence.
MethodsWe enrolled 28 patients who received APC therapy at the Kyungpook National University Hospital between May 2007 and April 2013. Clinical outcomes were analyzed.
ResultsThe median follow-up period was 24.8 months (range, 2 to 78). Among the 28 lesions treated using the APC procedure, tumor recurrence was encountered in seven lesions (25.0%). Recurrence was found in 50% (5/10) of single APC cases and 11% (2/18) of rescue APC cases. The mean time to recurrence was 16.1 months (range, 2 to 78). There were no serious APC-related complications such as perforation, bleeding, or infection.
ConclusionsAPC therapy can be a useful treatment with a favorable safety profile for patients with early gastric neoplasms. However, further studies are necessary to determine the long-term prognosis of patients undergoing this treatment.

Abstract
PDFPubReaderePub
A Dieulafoy's lesion is a vascular abnormality consisting of a large caliber-persistent tortuous submucosal artery. A small mucosal defect with the eruption of this protruding vessel can cause bleeding. In fact, a Dieulafoy's lesion is a relatively rare but potentially life-threatening condition. It accounts for 1% to 2% of cases of acute gastrointestinal bleeding. Although there is no consensus on the treatment of Dieulafoy's lesions; treatment options depend on the mode of presentation, site of the lesion, and available expertise. Endoscopic therapy is usually successful in achieving primary hemostasis, with hemostasis success rates reaching 75% to 100%. Although various therapeutic endoscopic methods are used to control bleeding in Dieulafoy's lesions, the best method for endoscopic intervention is not clear. Combination endoscopic therapy is known to be superior to monotherapy because of a lower rate of recurrent bleeding. In addition, mechanical therapies including hemostatic clipping and endoscopic band ligation are more effective and successful in controlling bleeding than other endoscopic methods. Advances in endoscopic techniques have reduced mortality in patients with Dieulafoy's lesion-from 80% to 8%-and consequently, the need for surgical intervention has been reduced. Currently, surgical intervention is used for cases that fail therapeutic endoscopic or angiographic interventions.

Abstract
PDFPubReaderePub
Endoscopic stent placement is a well-accepted and effective alternative treatment modality for complex and refractory esophageal strictures. Among the currently available types of stents, the partially covered self-expanding metal stent (SEMS) has a firm anchoring effect, preventing stent migration and ensuring effective covering of a narrowed segment. However, hyperplastic tissue reaction driven by the uncovered mesh may prevent easy and safe stent removal. As an alternative, a fully covered SEMS decreases the recurrence of dysphagia caused by hyperplastic tissue ingrowth; however, it has a high migration rate. Likewise, although a self-expanding plastic stent (SEPS) reduces reactive hyperplasia, the long-term outcome is disappointing because of the high rate of stent migration. A biodegradable stent has the main benefit of not requiring stent removal in comparison with SEMS and SEPS. However, it still has a somewhat high rate of hyperplastic reaction, and the long-term outcome does not satisfy expectations. Up to now, the question of which type of stent should be recommended for the effective treatment of complex and refractory benign strictures has no clear answer. Therefore, the selection of stent type for endoscopic treatment should be individualized, taking into consideration the endoscopist's experience as well as patient and stricture characteristics.

Abstract
PDFPubReaderePub
Barrett esophagus is recognized as a risk factor for the development of dysplasia and adenocarcinoma of the esophagus. Cancer is usually diagnosed at an advanced stage with a 5-year survival rate of 15%. Most of these patients present de novo and are not part of a surveillance program. Endoscopic screening with improvement in recognition of early lesions may change this pattern. In the past, patients diagnosed with dysplasia and mucosal cancer were best managed by esophagectomy. Endoscopic techniques such as endoscopic mucosal resection and radiofrequency ablation have resulted in high curative rates and a shift away from esophagectomy. This pathway is supported by the literature review of esophagectomies performed for mucosal disease, as well as pathologists' interpretation of endoscopic mucosal specimens, which document the low risk of lymph node metastasis. The role of endoscopic therapy for superficial submucosal disease continues to be a challenge.

Abstract
PDFPubReaderePub
Foregut neuroendocrine tumors (NETs) include those arising in the esophagus, stomach, pancreas, and duodenum and seem to have a broad range of clinical behavior from benign to metastatic. Several factors including the advent of screening endoscopy may be related to increased incidence of gastrointestinal NETs; thus, many foregut NETs are diagnosed at an early stage. Early foregut NETs, such as those of the stomach and duodenum, can be managed with endoscopic treatment because of a low frequency of lymph node and distant metastases. However, controversy continues concerning the optimal management of early foregut NETs due to a lack of controlled prospective studies. Several issues such as indications, technical issues, and outcomes of endoscopic treatment for early foregut NETs are reviewed based on some published studies.

Abstract
PDFPubReaderePub
A 73-year-old woman presented with intermittent abdominal pain and weight loss of 15 kg for 2 years. Colonoscopy revealed an erythematous polypoid tumor with a long and wide stalk in the cecum, but with air inflation, it abruptly went away through the ileocecal valve (ICV). An abdominal computed tomography showed a well-demarcated pedunculated subepithelial mass of 2.6×2.7 cm size with fat attenuation in the terminal ileum. It was an intussusceptum of the ileal lipoma through the ICV. This ileal lipoma was causing her symptoms because repeated ileocolic intussusceptions resulted in intermittent intestinal obstructions. In order to avoid surgical sequelae of ileal resection, snare polypectomy using cap-assisted colonoscopy technique was performed within the ileum without complications. The histopathology report confirmed it as a subepithelial lipoma. After endoscopic resection of the ileal lipoma, the patient has been free of symptoms and was restored to the original weight.

Abstract
PDFPubReaderePub
Though efficient acid suppression with proton pump inhibitors (PPIs) remains the mainstay of treatment of gastroesophageal reflux disease (GERD), some of the patients showed refractory response to PPIs, necessitating further intervention. After increasing dose of PPIs and other kinds of pharmacological intervention adopting prokinetics or others, variable endoscopic treatments are introduced for the treatment of these refractory cases. The detailed introduction regarding endoscopic treatment for GERD is forwarded in this review article. Implantation of reabsorbable or synthetic materials in the distal esophagus was tried in vain and is expelled from the market due to limited efficacy and serious complication. Radiofrequency energy delivery (Stretta) and transoral incisionless fundoplication (EsophyX) are actively tried currently.

Abstract
PDFPubReaderePub
Colorectal fecaloma is a mass of accumulated feces that is much harder in consistency than a fecal impactation. The rectosigmoid area is the common site for fecalomas and the cecum is the most unusual site. Diagnosis is usually made by distinctive radiographic findings of a mobile intraluminal mass with a smooth outline and no mucosal attachment. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, endoscopic procedures or a surgical intervention may be needed. We report here that a cecal fecaloma caused by intestinal tuberculosis scar was successfully removed by endoscopic procedures.

Abstract
PDFPubReaderePub
Afferent loop syndrome is a rare complication of gastrojejunostomy. Patients usually present with abdominal distention and bilious avomiting. Afferent loop syndrome in patients who have undergone a pylorus preserving pancreaticoduodenectomy can present with ascending cholangitis. This condition is related to a large volume of reflux through the biliary-enteric anastomosis and static materials with bacterial overgrowth in the afferent loop. Patients with afferent loop syndrome after pylorus preserving pancreaticoduodenectomy frequently cannot be confirmed as surgical candidates due to poor medical condition. In that situation, a non-surgical palliation should be considered. Herein, we report two patients with afferent loop syndrome presenting with obstructive jaundice and ascending cholangitis. The patients suffered from the recurrence of pancreatic cancer after pylorus preserving pancreaticoduodenectomy. The diagnosis of afferent loop syndrome was confirmed, and the patients were successfully treated by inserting an endoscopic metal stent using a colonoscopic endoscope.

- Endoscopic retrograde cholangiopancreatography has become a standard procedure for the diagnosis and treatment of pancreatobiliary disease. Like any invasive procedure, it carries a small, but significant rate of serious complications such as duodenal perforation. Primary surgical closure is the treatment of choice for the cases of duodenal perforation. However, there have been some case reports in which endoscopic metal clip closure of an iatrogenic duodenal perforation was successful. We experienced three cases of successful treatment of the iatrogenic duodenal perforation using endoscopic clipping and fibrin glue injections during a duodenoscope insertion.

Abstract

- Intramural gastric abscess is a rare condition representing a localized form of suppurative gastritis. According to the extent of the disorder, suppurative gastritis is classified into diffuse and localized types. The diffuse or phlegmonous type is more common and involves the entire stomach with inflammation spreading to all layers from the submucosa. The localized form referred to as "intramural gastric abscess" accounts for 5% to 15% of cases. The pathogenic mechanism includes direct invasion by microorganisms and hematogenous spread from a distant source. Cases are usually diagnosed with a combination of imaging modalities such as ultrasound, computed tomography, endoscopic ultrasound, and esophagogastroduodenoscopy. Herein we report a case of intramural gastric abscess that developed following ingestion of a fish bone. It was successfully treated with endoscopic incision and drainage of pus.

Abstract

- Situs inversus totalis (SIT) is very rare autosomal recessive condition, and patients with SIT have complete mirror image reversal of the thoracic and abdominal viscera. There have been no case reports of esophageal bezoar in a patient with situs inversus totalis. Bezoars are retained concretions of indigestible foreign material, including food material, vegetable material and hair, and they are usually founded in the stomach, small intestine and rectum. Esophageal bezoars are very rare, but they are known to occur in patients with anatomical defects or esophageal motility disorders. The treatment of esophageal bezoar is usually based on endoscopic fragmentation and extraction, dissolution with papain, cellulose, pancreatic enzyme and/or Coca cola. We report here on a case of an endoscopically treated primary esophageal bezoar in a patient with situs inversus totalis, and the patient experienced no complications from the treatment.

- An esophageal bezoar, although uncommon, is now recognized as a distinct clinical entity. An esophageal bezoar is rare but can form due to regurgitation of a gastric bezoar, motor disorder or anatomical abnormality, or following a gastrectomy. In general, bezoars are most often found in the stomach, and are formed by the accumulation of foreign ingested materials, including vegetable material and hair. In Korea, no case of a primary esophageal bezoar has been reported after a total gastrectomy. We report a case of an endoscopically treated primary esophageal bezoar that occurred after a total gastrectomy, without complications. (Korean J Gastrointest Endosc 2008;36:71-73)

- A duodenal duplication cyst is rare congenital anomaly, which accounts for 5% of all gastrointestinal duplication cysts. Most of the duodenal duplication cysts are usually found during infancy or early childhood, and present with obstructive symptoms. The most common clinical manifestations are an intestinal obstruction or, less commonly, hemorrhage, perforation, biliary obstruction or pancreatitis. The traditional treatment of a duodenal duplication cyst has been complete surgical resection, but very few cases of endoscopic treatment of a duodenal duplication cyst have been previously reported recently in the literature. Moreover, endoscopic treatment of a duodenal duplication cyst has not been reported in Korea. We report our first experience of a duodenal duplication cyst, including diagnosis and endoscopic management with a detachable snare. (Korean J Gastrointest Endosc 2007;35:190-195)

- Background
/Aims: This study evaluated the efficacy of endoscopic treatment in a bile leak that occurred through various causes. Methods: The medical records of 35 patients (mean age 55.4 years; male/female 25/10), who were diagnosed with a bile leak by endoscopic retrograde cholangiopancreatography in Yeungnam University Hospital from January 1998 to January 2006, were reviewed. Results: The most common cause of the bile leak was an open cholecystectomy (n=13, 37.1%) followed by a laparoscopic cholecystectomy (n=10, 28.6%), trauma (n=2, 5.7%), transarterial chemoembolization (n=3, 8.6%), spontaneous (n=3, 8.6%), and a hepatic resection (n=4, 11.4%). Thirty-four patients were treated endoscopically by the insertion of a plastic stent with/without a sphincterotomy (70.6%, 24/34), a nasobiliary drainage (11.8%, 4/34), or a sphincterotomy alone (17.6%, 6/34). Of these 34 patients, 30 were cured by the endoscopic treatment, 2 patients died from liver failure despite the use of nasobiliary drainage and 2 patients did not improve after endoscopic treatment. One patient underwent surgery without endoscopic treatment because of a transsection of the common bile duct. With the exception of the two who died from liver failure, the overall cure rate of endoscopic treatment was 90.9% (30/33). There were no complications associated with the endoscopic treatment. Conclusions: Endoscopic treatment for a bile leak is safe and effective regardless of the cause. (Korean J Gastrointest Endosc 2006;33:346352)

- Endoscopic treatment of chronic pancreatitis by stent insertion is an accepted procedure, but various complications can be induced, including proximal migration of the stent. Many techniques are used to retrieve proximally migrated, pancreatic stents. We here report a case of a proximally migrated stent into the dorsal duct of a pancreas divisum, which was retrieved endoscopically by using a mini-snare. A 39-year-old female patient had chronic pancreatitis with divisum. A stent was inserted into the dorsal duct to relieve the chronic pain. After two months, sudden epigastric pain developed due to proximal migration of the stent. The pancreatic stent was retrieved successfully with one endoscopic attempt using a mini- snare. The epigastric pain resolved after retrieval of the stent. Our observation is that pancreatic stent migration may cause severe abdominal pain and that endoscopic retrieval is possible.

- During endoscopy, most endoscopists insert endoscopes into the esophagus without visual aid in order to minimize the discomfort to patients. However, studies have shown that visual guided insertion imposes little discomfort, is safe and can increase the diagnostic rate of abnormal pathology of the throat. As for the treatment of hypopharyngeal lesions, cases of endoscopic treatment are rare and any guidelines have not been clearly defined yet. However, endoscopic treatment may be feasible in selected cases. Several procedures, such as endoscopic mucosal resection with cap (EMR-C) and saline injection polypectomy can be applied. We experienced seven patients who had benign hypopharyngeal masses that were removed endoscopically without serious complications. Compared to surgical treatment, endoscopic removal of the benign hypopharyngeal tumors does not require general anesthesia; it is simple, less invasive and less costly. Therefore, endoscopy should be regarded as a treatment option. However, further studies are required before widespread application of endoscopic removal for the definitive treatment of hypopharyngeal masses, including malignancies.

/Aims: The ingestion of foreign bodies in the upper gastrointestinal tract usually happens as a result of accidental swallowing, and rarely produces symptoms. Although most foreign bodies are eliminated spontaneously, 10∼20% of cases need treatment with endoscopy. We evaluated the role of endoscopy for removing foreign bodies from the upper gastrointestinal tract. Methods: We analyzed one hundred and thirty-nine cases of foreign bodies in the upper gastrointestinal tract which were endoscopically treated at Chungnam National University Hospital from January 2001 to July 2004. Results: Patients' age ranged from 6 months to 96 years old (mean 36.0 years old). The ratio of males to females was 1.2:1. The common foreign bodies included coins (29 cases) and fish bones (23 cases), animal bones (19 cases), and stones (15 cases) follows in order. The most common location was the esophagus (79.9%). In most cases (73.4%), the foreign body was removed using an alligator tooth and a grasping forceps. Twenty-eight among one hundred and thirty-nine patients had a co-morbid condition, such as esophageal disease, diabetes mellitus, hypertension, stomach cancer, or a psychiatric disorder. Conclusions: Endoscopic removal is a very powerful and useful method for removing foreign bodies from the upper gastrointestinal tract. Nevertheless, a simpler and more efficient endoscopic equipment is required. (Korean J Gastrointest Endosc 2005;31:135139)

- Foreign bodies of the upper gastrointestinal tract are usually discovered in children, persons with esophageal disease, prisoners with a purpose of secondary gain, and mentally disturbed or disabled individuals. In adults, accidentally or intentionally ingested foreign bodies such as dentures, coins, corks, toothbrush, needles, and nails are reported. To our knowledge, there has been one case of gastric bezoar caused by glue ingestion that was removed by surgical operation in Korea. However, there has been no case report of esophageal foreign body caused by glue ingestion neither in Korea nor elsewhere. We report a case of a man with a history of chronic glue inhalation, who ingested glue with suicidal intent, that was solidified from the upper esophagus to the stomach. It was successfully removed by therapeutic endoscopy. (Korean J Gastrointest Endosc 2005;30:2427)

- Background
/Aims: The majority of foreign body ingestions occur in pediatric population. We assessed the characteristics and endoscopic treatment outcome of esophageal foreign bodies in adults. Methods: Medical records of consecutive 257 patients who received trial of endoscopic treatment for esophageal foreign bodies, from January 1998 through November 2003 in Gyeongsang National University Hospital, were analyzed retrospectively. Results: Among 257 cases, 132 were male. The incidence was highest in 5th decade, and mean age was 54.6 years. Most common location was upper esophagus (84.6%). Accidental ingestion accounted for 92.2%. Twenty cases (7.8%) of voluntary ingestion were all prisoners or in psychiatric problems. Fish bone was the most common type. Endoscopic treatment was successful in 253 cases (98.4%) and 4 were managed with rigid esophagoscopy. Four cases who complicated by acute mediastinitis or pneumomediastinum at presentation had sharp-pointed or long objects lodged in upper esophagus, and almost presented at 48 hours after the ingestion. Full esophagogastroduodenoscopy could find 37 organic lesions in 35 cases. Conclusions: Majority of esophageal foreign bodies in adults developed accidentally during meals. Voluntary ingestion of foreign bodies was not related to meals, and developed by prisoners or psychiatric patients. The sharp-pointed or long objects lodged in upper esophagus with delayed presentation may cause complication. Endoscopic treatment is safe and beneficial, and a full endoscopic evaluation should be recommended for the evaluation of a synchronous organic disease. (Korean J Gastrointest Endosc 2004;29:5157)

Abstract

- Intramural dissection of the esophagus is a rare esophageal disorder which reveals characteristic endoscopic and radiologic features. Some authors have recognized that this injury is an intermediate stage between a transmural esophageal rupture (Boerhaave's syndrome) and an esophageal mucosal tear (Mallory-Weiss syndrome). Presenting symptoms are sudden severe retrosternal pain, hematemesis, odynophagia, and dysphagia. The diagnosis is made by contrast esophagography, esophageal endoscopy, or both. Conservative management is usually successful. Surgery should be reserved for the cases of protracted disease or perforation with mediastinitis. We report a case of spontaneous intramural esophageal dissection, in which the symptom of dysphagia did not improve with a conservative management. Then we treated with an endoscopic incision of the septum between the true and false lumens using a needle type papillotome. (Korean J Gastrointest Endosc 2003;27:527530)

- Background
/Aims: It has been reported that lymph node (LN) metastasis occurs in approximately 10 percent of patients with submucosally invasive colorectal carcinoma. The present study was performed to determine the clinical significance of absolute and relative depth of submucosal invasion and to find the associated pathological risk factors of LN metastasis in submucosally invasive colorectal carcinoma. Methods: From June, 1989 to May, 1999, 2,580 patients were pathologically confirmed as having colorectal carcinoma, Of these patients, a total of 61 subjects with submucosally invasive carcinoma could be reviewed pathologically and were included in this retrospective analysis. The relative depth of submucosal invasion was evaluated by Kudo (sm1, 2, 3) and modified Haggitt (L1, 2, 3) classifications, and the absolute depth was measured, Results: The absolute depth of submucosal invasion was significantly correlated with the relative depth evaluated by both Kudo and modified Haggitt classifications (p<0.01). Of 51 patients in whom the status of LN metastasis could be evaluated, six (11.8%) showed LN metastasis, Among the patients with LN metastasis, there was no one with sm1or L1in the relative depth and 500 ㎛or less in the absolute depth. The risk of LN metastasis was related to the gross type, and lymphatic or vessel invasion (p <0.05). Conclusions: The risk factors for LN metastasis in submucosally invasive colorectal carcinoma were the gross type and lymphatic or vessel invasion, The results also suggest that the absolute depth of submucosal invasion might be a useful parameter to select the patients for the endoscopic treatment, (Korean J Gastrointest Endosc 2001;22:411- 418)

- Duodenal diverticula are first reported by Chomel in 1710. Duodenal diverticula are relatively common in adults with a prevalence of 23% in SRCP. The most duodenal diverticulum is asymptomatic. Complications such as obstruction, cholangitis, blliary stones, ulceration, perforation and hemorrhage can occur in approximately 10%. However, relatively few cases of bleeding from a duodenal diverticulum have been reported. The cause of bleeding from a duodenal diverticulum is uncertain and various suspected etiologies were suggested, such as ectopic gastric mucosa, stasis-induced ulceration, erosion into major vessels, aortoenteric fistuias, intradiverticujar polyp, aspirin-induced erosion. We report a case of a bleeding duodenal diverticulum by a Dieulafoy-like lesion and suggest this 1esion as one of posslble causes of blee4ng in duodenal diverticulum.

Abstract

- Dieulafoy-like lesion is a relatively uncommon disease which is a potential source of life-threatening gastrointestinal bleeding. The lesion comprises mainly of an abnormally large submucosal artery that protrudes through a small mucosal defect. The lesion is frequently found at distal portion of gastroesophageal junction but may occur anywhere in gastrointestinal tract including small bowel, colon and rectum. Moreover bleeding from dieulafoy-like lesion of rectum is very reae. It has been reported that rectal Dieulafoy-like lesion is very rare source of lower gastrointestinal bleeding and its pathogenesis may be associated with constipation. Recently, endoscopy has an important role in the diagnosis and treatment (including injection and coagulation therapy) of bleeding from Dieulafoy-like lesion. We herein report a case of a patient who presented wih massive hemorrhage from a small rectal ulcer with adherent blood clots. Bleeding was controlled with endoscopic treatment by utilizing bipolar electrocoagulation without complication and recurrence.(Korean J Gastrointest Endosc 2000;21:577-580)

Abstract

- Duodenal divertula are relatively frequent findings in the adult gastrointestinal tract. The majority of them are asymptomatic, but vague gastrointestinal complaints have often been attributed to these lesions. These diverticula occasionally result in the obstruction of the biliary and pancreatic ducts, which leads to jaundice and pancreatitis. Other complications such as hemorrhage, perforation, sepsis, and death can occur. With the advent of therapeutic endoscopy, the diagnosis and primary treatment of duodenal diverticula associated with bleeding has changed dramatically since its first reported occurrence. Effectiveness of therapeutic endoscopy is very high in patients with diverticular bleeding in the medial aspect of sencond portion of the duodenum because of its high operative mortality. A cases of a patient suffering from gastrointestinal bleeding in the duodenal diverticulum who was diagnosed and managed by endoscopy alone is herein reported with review of relevant literature.
