Successful Management of Periampullary Diverticular Bleeding with Hemoclipping Using Side-viewing Endoscope during Endoscopic Retrograde Cholangiopancreatography / 대한소화기학회지

Periampullary diverticulum is commonly found during endoscopy and can occur at any age although its prevalence increases with age. Periampullary diverticular bleeding is a rare and difficult to diagnose during clinical practice because of its unique appearance and location. This often can lead to massive bleeding and interfere with adequate bleeding control. Endoscopic management on duodenal diverticular bleeding is limited compared to colonic diverticular bleeding due to lack of experience. Herein, we report a case of active bleeding from a periampullary diverticulum during bile duct stone extraction diagnosed by side-viewing endoscope and successfully controlled using hemoclips without any complications.

Metallic hemoclips in management of gastric defects during endoscopic full-thickness resection / 中华消化内镜杂志

Objective To evaluate the clinical efficacy and safety of metallic hemoclips in the treatment of gastric defects during endoscopic full-thickness resection. Methods Patients with submucosal tumors derived from the muscularis propria and adhesion of the gastric serosa diagnosed by EUS and CT were enrolled in the study.A total of 62 patients,22 males and 40 females,mean age 58.5 years,were recruited into the present study from June 2009 to December 2010,in which 37 patients were with tumors in gastric fundus,20 in gastric body and 5 in antrum.All patients were treated with endoscopic full-thickness resection.After the operation,metallic hemoclips were used to close the defects through endoscopic biopsy channel.The closure success rate with metallic hemoclips were assessed.The patients were followed up endoscopically for evaluation of efficacy and safety of the procedures.Results All patients underwent endoscopic full-thickness resection.Uncontrollable bleeding occurred in 1 patient,who subsequently underwent emergent laparoscopic surgery and was excluded from the study.Metallic hemoclips were applied to close defects in 57 patients,and metallic hemoclips combined with omentum obstruction in 4 patients.The overall success rate was 100％ in 61 patients.Endoscopic follow-up was completed in all patients in average of 4.4 months.The clinical wound healing rate was 100％.No complications such as fever,abdominal pain were found in 2months after the procedures.Conclusion Application of metallic hemoclips during endoscopic full-thickness resection for gastric defects is a safe and effective technique.

Endoscopic ultrasonography for defining primary tumor in esophageal radiotherapy / 中华消化内镜杂志

Objective To investigate the differences of measurement of gross target volume (GTV)between endoscopic ultrasonography ( EUS )-based ( GTVEUS ) and computed tomography ( CT ) -based (GTVCT) method for thoracic esophageal squamous cell carcinoma. Methods EUS was performed on 36consecutive patients with thoracic squamous cell carcinoma, and the superior and inferior boarders of the tumor defined by EUS were marked with hemoclips. The CT planning scan was then performed with the patient in supine position, and the GTVCT and GTVEUS were contoured respectively. The lengths ( LCT and LEUS) and spatial locations of longitudinal GTVCT and GTVEUS were compared. Results The mean LCT and LEUS were (7. 79 ± 3. 15 ) cm and (7. 42 ± 2. 72) cm, respectively ( t = 0. 82, P ＞ 0. 05 ), with a correlation coefficient of 0. 61 (P ＜0. 001 ). Locations of longitudinal GTVCT and GTVEUS were compared in 34cases, with 2 excluded for invisualization on CT. The mean conformal index (CI) was (0. 79 ± 0. 18 ), and spatial variations were found in 71% patients, with 8 patients at proximal end and 21 others at distal end.There was no clip placement associated complication. Conclusion Endoscopic hemoclips placement is safe and reliable. EUS can provide additional information to CT in defining longitudinal GTV in thoracic esophageal squamous cell carcinoma, especially in superficial and submucosal carcinomas.

A Primary Repair with Hemoclips and Fibrin Glue Injection in Biliary Stent Induced Duodenal Perforation / 대한소화기내시경학회지

Duodenal perforations caused by biliary prostheses are uncommon, but they are potentially life threatening and require immediate treatment. Here we describe an unusual case of duodenal perforation induced by a plastic biliary stent. It masqueraded as a case of cholecystitis and combined systemic upset with a localized peritonitis and fever. Primary endoscopic closure by hemoclips was difficult due to the position of the lateral wall and the complexity of aligning the perforation with the endoscope. To approximate the perforated hole and adherent hemoclips, glue injection and sprayings were successfully performed under cap-fitted endoscopy. The patient recovered without additional complications.

Clinical features and endoscopic treatment for aged patients with acute hemorrhage arising from vascular malformation of colon / 中华消化杂志

Objective To investigate the clinical features of aged patients with acute hemorrhage arising from vascular malformation of colon and the efficacy of endoscopic placement of hemoclip in treatment of hemorrhage. Methods Fifty-six patients were diagnosed with acute bleeding arising from vascular malformation of colon by colonoscopy. Patients were assigned to aged group (n = 31,≧60 years of age) and control group (n = 25, <60 years of age). The clinical manifestations and the efficacy of emergent endoscopic treatment with hemoclip application were compared between two groups. Results The complications including hypertension, coronary heart disease and diabetes were higher in aged group [80. 6% (25/31)] than in control group [40. 0% (10/25) ] with significant difference (P<0. 01). The effusive bleeding accounted for 45. 2% (14/31) in aged group and 16. 0% (4/25) in control group (P<0. 05). Endoscopic treatment with hemoclip was performed in 18 and 6 patients in aged group and control group, respectively. Initial hemostasis was achieved in 17 and 6 patients in the aged group and control group, respectively (P<0. 05). Recurrent hemorrhage occurred in 2 patients in the aged group and none in the control group (P>0. 05). The mean number of hemoclips application was 5. 3 ± 2. 4 in aged group and 3. 1 ± 1. 3 in control group (P<0. 05). Conclusions The hemorrhage is more serious in aged patients with acute hemorrhage, because they often complicate with cardiovascular diseases and diabetes. The lesion of hemorrhage can be found and precisely localized using colonoscopy. Promptly endoscopic placement of hemoclip is quite effective in treatment of acute hemorrhage.

Extensive Gastric Mucosal Laceration During Endoscopic Examination / 대한소화기내시경학회지

Gastric mucosal lacerations occurring during the course of upper gastroduodenal endoscopy are apparently rare. The location and extent of the lesion are little different from the usual one found in the Mallory-Weiss tear. But the pathogenesis of the gastric mucosal tear is similar to that of Mallory-Weiss tear. Hiatal hernia, atrophic gastritis, and old age are predisposing factors for Mallory-Weiss tear. There is currently only one report about extensive gastric mucosal laceration during performance of endoscopy in an elderly patient. During a standard diagnostic endoscopic procedure, we experienced extensive gastric mucosal laceration that ranged from the gastroesophageal junction to the gastric angle in an elderly woman Furthermore, her body surface area and stomach size were very small. The patient was treated successfully with hemoclip application for the laceration. We report on the case along with a review of the relevant literature.

A Case of Successful Embolization with Superselection by Endoscopic Hemoclipping for Pseudoaneurysmal Bleeding in a Patient with Pylorus Preserving Pancreaticoduodenectomy / 대한소화기내시경학회지

Arterial bleeding after pancreaticoduodenectomy is a very serious complication with high mortality. Therefore, early diagnosis and treatment is essential. In particular, early detection and immediate embolization can be effectively used for the delayed massive bleeding that occurs from a pseudoaneurysmal rupture. However, sometimes intermittent bleeding or a vessel spasm can cause the bleeding focus to remain unidentified in spite of repeated angiography. We experienced a case of successful embolization with superselection by endoscopic hemoclipping in a patient who underwent pylorus preserving pancreaticoduodenectomy, and the patient's bleeding focus was not found after repeated angiography. Endoscopic hemoclip application can be useful for localizing a pseudoaneurysmal rupture in patients with pancreaticoduodenectomy.

Two Cases of Boerhaave's Syndrome Treated by Endoscopic Hemoclipping / 대한소화기내시경학회지

Boerhaave's syndrome is a spontaneous esophageal perforation due to severe nausea and vomiting after hyperphagia or drinking, and it is not due to trauma, medical instrumentation or a foreign body. Untreated esophageal perforation is associated with high mortality, and the traditional treatment has been surgical drainage and primary repair of the perforation. However, non-surgical primary repair with an endoscopic procedure has recently been attempted in some selected patients with a small sized perforation, limited contamination of the mediastinum and no evidence of sepsis. We report here on 2 patients with Boerhaave's syndrome and who were successfully treated via primary repair with endoscopic hemoclips, and we review the other cases of the Boerhaave's syndrome that were treated with a endoscopic procedure.

A Case of Successful Endoscopic Management of Afferent Loop Leakages by Using Hemoclips and a Detachable Snare / 대한소화기내시경학회지

There are many complications following gastrectomy and one of the most frequent complications is anastomosis site leakage. Postoperative leakage is a serious complication in patients after they undergo gastric surgery. It can lead to the progressive deterioration in the patient's condition and quality of life and the mortality rate is nearly 60%. We encountered a case of a 75 year-old man who had the leakage of the jejunal end of the Roux limb after total gastrectomy. We performed treatment of the leakage endoscopic clipping and detachable snaring. Hemoclips were fixed at the margin of both sides of the lesion. A detachable snare was used to bind both hemoclips, so the interval was made narrow. After snare binding, five hemoclips were used for final closure of the small interval. After treatment, the leakage of the afferent loop end was completely stopped. He resumed an oral intake and was discharged without complications.

A Case of Bronchoesophageal Fistula Mimicking Pulmonary Tuberculosis / 결핵및호흡기질환

Benign bronchoesophageal fistula is a rare disease and it may be characterized by nonspecific symptoms that can cause a delayed diagnosis. We misdiagnosed a patient with recurrent aspiration, which was due to bronchoesophageal fistula, as active pulmonary tuberculosis. The patient was 44 year old female who had suffered from chronic cough, especially during eating liquid meals, since 1982 when she had been treated for tuberculous lymphadenitis. Computed tomography showed an irregular mass with surrounding centrilobular nodules in the superior segment of the right lower lobe (RLL). She was diagnosed as having active pulmonary tuberculosis and treated with anti-tuberculosis medication, but she continued to complain of persistent cough even after anti-tuberculosis treatment. Thus, we reexamined the patient, and bronchoesophageal fistula between the esophagus and the superior segment of the RLL was finally confirmed by esophagography. After the fistula was surgically treated, the patient became asymptomatic and she then experienced good health.

A Case of Successful Closure using Endoscopic Hemostatic Clips with a Detachable Snare and Fibrin Glue Injection for a Gastro-Cutaneous Fistula following Buried Bumper Syndrome / 대한소화기내시경학회지

The buried bumper syndrome is a well-recognized long-term complication of a percutaneous endoscopic gastrostomy (PEG). Most of the buried bumpers are removed by making an external incision over the PEG site under local anesthesia or during a laparotomy. Recently, endoscopic removal is usually attempted. While the removal of the PEG tube is usually followed by spontaneous closure of the gastrostomy tract, a non-healing gastro-cutaneous fistula is difficult to manage. The fistula is generally treated with bowel rest and total parenteral nutritional support, suppression of gastric acid secretion, and occasionally, surgical exploration and wedge excision of the fistula site are performed. However, in debilitated patients, surgical management is accompanied with high morbidity and mortality. Recently, the use of nonsurgical alternative methods, such as endoscopic therapy using tissue adhesives or hemostatic clips, has emerged with recent advances in endoscopic technology. We report a case of successful closure using endoscopic hemostatic clips with a detachable snare and fibrin glue injection for a gastro-cutaneous fistula following buried bumper syndrome.

Two Cases of Rectal Dieulafoy's Lesion with Massive Hematochezia in Elderly Patients

Dieulafoy's lesion is rare cause of massive gastrointestinal bleeding. Dieulafoy's lesion is understood to represent a tiny submucosal defect with fibrinoid necrosis at its base, overlying a large, tortous, thick-walled artery in the muscularis mucosa. Although the original descriptions and early reports were of lesions in the proximal stomach, similar lesions have subsequently been reported in the esophagus, duodenum, jejunum, colon and rectum. Rectal Dieulafoy's lesion is rare but it is one of the causes of massive hematochezia. We report two cases of rectal Dieulafoy's lesion that was successfully treated with endoscopic hemostasis by clipping in the elderly patients.

Hemoclipped Dieulafoy's Lesion in Giant Diverticulum in the 3rd Portion of Duodenum / 대한소화기내시경학회지

A duodenal diverticulum is common in the second portion of the duodenum and can occur at any age. An obstruction, bleeding, perforation, diverticulitis are not an uncommon complicationa of duodenal diverticulum. As a rare complication, bleeding in the duodenal diverticulum may be massive, and duodenal diverticulum is resected primarily as a result of the difficulty in determining the site of bleeding. However, there has been a recent increase in endoscopic diagnosis and the treatment of diverticular bleeding. Band ligation increases the risk of duodenal diverticular perforation because of the thin diverticular wall. An endoscopic hemoclip is a preferable method for endoscopic sclerotherapy. We report a 48- year-old man with a giant duodenal diverticulum that was treated with a hemoclip. The duodenal diverticular perforation was treated effectively with supportive care.

Two Cases of Rectal Dieulafoy's Lesion Treated Sucessfully with Hemoclip / 대한소화기내시경학회지

Dieulafoy's lesion is a rare cause of massive gastrointestinal bleeding. It is usually identified within the proximal stomach but has been reported in the esophagus, duodenum, small intestine, colon and rectum. Surgery was originally the treatment of choice for this lesion. However, recently, most case can be treated using endoscopic techniques including an injection of a sclerosing agent, clipping, band ligation, heater probe, and bipolar coagulation. We report 2 cases of a rectal Dieulafoy's lesion that were treated sucessfully by endoscopic clipping without complications.

Comparison of Hemostatic Efficacy between Epinephrine Injection Alone and a Combined Therapy with Hemoclip for Bleeding Peptic Ulcers / 대한소화기내시경학회지

BACKGROUND/AIMS: Many studies have been performed to find the differences between using epinephrine injection alone and a combination therapy with hemoclip for bleeding peptic ulcer, but the results have been controversial. We retrospectively evaluated the hemostatic efficacy for epinephrine injection alone and injection combined with hemoclip for bleeding peptic ulcers. METHODS: Four hundred patients were enrolled. They were assigned to one of the two groups: endoscopic hemostasis with injection of epinephrine (group I, n=156) and combined epinephrine injection with hemoclip (group II, n=244). RESULTS: The continuous bleeding rate was significantly higher in group I than in group II. The recurrent bleeding rate was also significantly higher in group I than in group II. There were no statistical differences in the rates of death, emergency surgery and arterial embolization. The rates of continuous bleeding and the initial failure of hemostasis were higher for the patients with active bleeding on the initial endoscopy irrespective of the applied hemostatic methods. CONCLUSIONS: A combination of epinephrine injection and hemoclip is more effective than epinephrine injection alone for treating bleeding peptic ulcers.

A Case of Endoscopic Management of Dieulafoy's Lesion in the Ampulla of Vater / 대한소화기내시경학회지

Dieulafoy's lesion is an uncommon but important cause of massive upper gastrointestinal bleeding. The lesion usually occurs in the lesser curvature of the stomach within 6 cm of the gastroesophageal junction but extragastric locations of Dieulafoy's lesion are rare. In this study, diagnosis of Dieulafoy's lesion was frequently made by endoscopy instead of surgery. Hemostasis was achieved by endoscopic treatment in more than 90% of patients. We report the successful application of endoscopic hemoclipping for treatment of active bleeding from Dieulafoy's lesion in the ampulla of Vater of the duodenum.

Duodenal Perforation due to Hemoclipping for the Dieulafoy's Lesion in a Duodenal Diverticulum / 대한소화기내시경학회지

Duodenal diverticulum usually originates in the second portion of the duodenum and occasionally causes duodenal obstruction, hemorrhage, perforation and diverticulitis. A bleeding from Dieulafoy's lesion in a duodenal diverticulum is rare. It is not easily dignosed and treated by forward viewing endoscopy. Recently, a case was reported describing the hemorrhage from the Dieulafoy's lesion in a duodenal diverticulum which was treated by hemoclip with forward viewing endoscopy. Hemoclip application is considered to be the most appropriate endoscopic treatment, because sclerotherapy, electrocoagulation or band ligation for Dieulafoy's lesion in the duodenal diverticulum may increase risk of duodenal perforation. We report a case of duodenal perforation due to hemoclip application for the treatment of Dieulafoy's lesion in a duodenal diverticulum.

A Case of Lower GI Bleeding from Portal Hypertensive Colopathy Successfully Treated with Octreotide Administration and Endoscopic Hemoclipping / 대한소화기내시경학회지

Cirrhotic patients with portal hypertension are often found to have changes in their colonic mucosa. Such mucosal changes are termed portal hypertensive colopathy. Most patients with portal hypertension remained asymptomatic but some may show massive bleeding. The mainstay of treatment for portal hypertensive gastropathy include non-surgical methods such as octreotide injection, endoscopic hemostasis, and interventional methods such as TIPS. However, treatment for portal hypertensive colopathy remained unresolved. The authors here report a case of a 41 year old male with liver cirrhosis admitted for fever and abdominal pain, who reported an episode of hematochezia in the course of admisssion period. Subsequent colonoscopy revealed angiodysplasia-like lesions throughout the entire colon. We observed that such lesions were the source of hematochezia and that direct clipping with octreotide injection was successful in controlling the bleeding.

A Case of Successful Treatment of a Bleeding Duodenal Ulcer with Endoscopic Hemoclipping in a Child / 대한소화기내시경학회지

Upper gastrointestinal bleeding in infant and children is much less common than that in adults. Upper gastrointestinal bleeding in infants and young children is most often acssociated with stress ulcer or erosions, but in older children it may also be caused by duodenal ulcer, esophagitis, and esophageal varices. Because the total blood volume of a child is relatively small and can deplete rapidly, gastrointestinal bleeding is a catastrophic event. However, it is not associated with significant mortality except in those with a severe primary illness. Data on therapeutic endoscopy for pediatric gastrointestinal bleeding are limited to case reports. The hemoclip has recently been added to armamentaria of endoscopic devices. This method has several advantages, including fewer complication and the fact that less expertise is needed to achieve permanent hemostasis. We report a case of successful endoscopic control of a bleeding duodenal ulcer using with a hemoclip in a 22-month-old boy. Endoscopic hemoclipping would be a safe and efficacious treatment for control of bleeding from peptic ulcers in children.

Clinical Feature and the Effects of Endoscopic Band Ligation of Dieulafoy-like Lesion / 대한소화기내시경학회지

BACKGROUND/AIMS: The Dieulafoy lesion is an important cause of gastrointestinal bleeding. The bleedings from caliber- persistent vessel or abnormally large and tortuous submucosal artery are usually located on proximal stomach. Endoscopic band ligation (EBL) is currently regarded as the treatment of choice of Dieulafoy lesions. This study reports on the clinical features, the efficacy and safety of EBL. METHODS: 10 patients with Dieulafoy-like lesion (median age: 47 yr range: 22~71, M:F 8:2 ) were treated using EBL. EBL was performed as the primary hemostatic tratment as follows in 8 cases of urgency and 2 cases of emergency. RESULTS: The location of all lesions (n=10) were in stomach, 8 in body (4 in posterior wall), 2 in fundus. The bleeding focuses were identified during the first endoscopy. Five lesions were bleeding, 5 had adherent clots or protruding vessels without active bleeding. Hemostasis were achieved with first session of EBL in 9 patients successfully, one case in the fundus was failed due to early band release. CONCLUSION: EBL is a simple, effective, and safe endoscopic method of Dieulafoy-like lesions and, it should be proposed as a primary option.
