The Application of Clips during ERCP: A New Anchoring Method for Redundant Kerckrings Folds Covering the Duodenal Papilla / 대한소화기내시경학회지

During an endoscopic retrograde cholangiopancreatography (ERCP). cannulation is more difficult in patients with anatomical variations, papillary stenosis, an impacted stone in the papilla, papillary cancer, peripapillary diverticulum, postoperative states such as those after Billroth II or Braun operations, or redundant Kerckring's folds of the duodenum covering the duodenal papilla. For a patient suffering from a redundant Kerckrings folds of the duodenum and a common bile duct stone, a new technique applying clips to expose the duodenal papilla properly during ERCP was performed. After the application of the clips, the duodenal papilla was well exposed in a favorable position for proper cannulation. In this setting, an ERCP was easily performed with the standard cannula. After an endoscopic sphincterotomy (EST) with the pull-type papillotome was conducted, the common bile duct stone was successfully removed with a Dormia basket.

Percutaneous Endoscopic Biliary Stenting (PEBS) Using the Percutaneous Fine Needle Puncture Method in Malignant Complete Biliary Obstruction / 대한소화기내시경학회지

Nonsurgical drainage of malignant obstructive jaundice is an interesting alternative to surgical drainage in the palliative treatment of pancreaticobiliary neoplasms. Biliary drainage by endoprosthesis is as effective and better supported than percutaneous external drainage, but more difficult to control. Endoscopic retograde biliary drainage (ERBD) is a safe and effective biliary drainage procedure, and is indicated with malignant obstructive jaundice in patients on whom endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) can be performed. A nonoperative method of palliation was used in patients with malignant obstructive jaundice, in whom a biliary endoprosthesis could not be placed endoscopically due to complete obstruction of the bile duct. A guide wire was manipulated through the lesion by a percutaneous transhepatic route, after puncturing the tumor by a fine needle, and retrieved from the duodenum through an endoscope. A stent was then passed through the endoscope over the guide wire across the stricture.

Results of Endoscopic Treatment in Common Bile Duct Stones / 대한소화기내시경학회지

BACKGROUND/AIMS: Common bile duct stones are the most common among bile duct diseases. In the past, common bile duct stones were considered a surgically operable disease, but is now considered a medical disease due to the advancement of endoscopy and endoscopic techniques. The aim of this study was to determine the results of endoscopic treatment of common bile duct stones. METHODS: Removal of primary or secondary common bile duct stones were attempted by peroral or percutaneous endoscopy. The common bile duct stones were diagnosed by ultrasonography or cholangiography. As a primary approach route, the peroral transpapillary endoscopic approach was tried. On the other hand, percutaneous common bile duct stone removal was attempted if the patient already had a percutaneous route, peroral transpapillary approaches failed, or if conditions for endoscopy were unfavorable. RESULTS: The study subjects consisted of 196 patients; 96 males and 100 females. The mean age was 61.8 years. A total of 272 endoscopic stone removal were attempted in 196 patients. Of the 272, peroral approaches were conducted 241 times for 183 patients, and percutaneous approaches were performed 31 times for 12 patients. The success rate of the first treatment modality to remove the common bile duct stones was 90.3% (176/195). The overall success rate of endoscopic common bile duct stones removal was 100%. CONCLUSIONS: In all patients, the common bile duct stones were removed successfully by endoscopy, and thus supporting the shift of recognizing common bile duct stones as a medical rather than surgical discase.

Endoscopic Variceal Ligation plus Octreotide versus Variceal Ligation Alone for the Prevention of Early Rebleeding from Esophageal Varices / 대한간학회지

BACKGROUND/AIMS: Endoscopic variceal ligation (EVL) has been effective modality for esophageal variceal bleeding, but recurrent bleeding occurs 20 to 40% of patients. So there has been an increased interest in the use of vasoactive drugs to lower portal hypertension and help control variceal bleeding before and after endoscopy. We investigated the efficacy of octreotide (OCT) infusion as an adjunct to EVL for preventing early rebleeding from varices. METHODS: From Jan. 1997 to Feb. 1999, fifty four patients with endoscopically documented esophageal variceal bleeding were included. The patients were randomly treated by EVL alone (EVL group, n=30) or EVL plus octreotide (EVL+OCT group, n=24). We evaluated the 5-ay and 6-eek rebleeding rate and 6-eek mortality. RESULTS: Baseline characteristics were similar in two group but hospital stay (p=0.028) and units of transfused blood (p=0.043) were significantly less in EVL+OCT group. There were no significant differences on 5-ay rebleeding rate (EVL group; 7%, EVL+OCT group; 0%) and 6-eek rebleeding rate (EVL group; 20%, EVL+OCT group; 4%). CONCLUSIONS: The combined therapy did not decrease early rebleeding and mortality, but it was superior to EVL alone in hospital course such as requirement of transfusion and duration of hospitalization.

N-utyl--yanoacrylate (Histoacryl) in the Treatment of Esophageal Variceal Bleeding: Comparison with Band Ligation / 대한간학회지

BACKGROUND/AIMS: Endoscopic sclerotherapy and band ligation have been well documented beneficial therapeutic options of esophageal variceal bleeding. But acute variceal bleeding is refractory to sclerotherapy in upto one-hird of patients, and rebleeding occurs in 30% to 50%. Recently alternative endoscopic modality, N-utyl--yanoacrylate (Histoacryl) injection is performed in intravariceal sclerotherapy but its efficacy and safty are not clearly established. We evaluated the efficacy of Histoacryl on esophageal variceal bleeding and compared with that of endoscopic band ligation in the present study. MATERIALS/METHODS: From March 1994 to March 1998, ninety seven patients with endoscopically documented esophageal variceal bleeding were enrolled. Histoacryl injection (Histoacryl group, n=33) or endoscopic band ligation (EVL group, n=64) was done for esophageal variceal bleeding. We evaluated the rebleeding rate and in-ospital mortality in both groups. RESULTS: Baseline characteristics were similar but active bleeding on first endoscopic session was significantly higher in Histoacryl group (Histoacryl group; 90.7%, EVL group; 26.6%, p=0.002). Successful hemostasis was done at 87.9% in Histoacryl group, 95.3% in EVL group (not significant). There were no significant differences on early rebleeding rate (18.2% vs 23.4%), late rebleeding rate (39.4% vs 37.5%) and in-ospital mortality (24.2% vs 15.6%) between Histoacryl group and EVL group. There were no technique-elated fatal complications at Histoacryl injection group. CONCLUSION: Therapeutic efficacy of Histoacryl injection was similar to the endoscopic band ligation in patients with esophageal varix bleeding in terms of hemostasis and rebleeding. Histoacryl is effective therapeutic option for esophageal variceal bleeding as well as gastric variceal bleeding.

Comparison of Various Endoscopic Injection Therapy and Hemoclipping for Bleeding Peptic Ulcers / 대한소화기내시경학회지

BACKGROUND/AIMS: Widely practiced endoscopic methods for hemastasis of bleeding peptic ulcer include thermal application (laser, heater probe) and local injection (epi- nephrine, fibrine-glue or various sclerosing agents). Studies evaluating these modalities have presented high success rates for achieving initial hemostasis. Recently, endoscopic hemoclipping is considered to be a safe and effective hemostatic method for upper gas- trointestinal bleeding. The aim of this study was to compare various hemostatic modalities for bleeding peptic ulcer. METHODS: Over a three year period between June 1994 and October 1997, a total of 133 patients with bleeding peptic ulcer were included in this study, We have conducted clinical trials and a retrospective analysis. All of the patients we selected had either active bleeding or a nonbleeding visible vessel on endoscopy. Endoscopy was performed on an emergency basis within 12 hours of hospital arrival.

Triple Intravenous Bolus Injection of Recombinant Tissue-Type Plasminogen Activator in Acute Myocardial Infarction

BACKGROUND: Previous studies indicated that there was important correlation between early patency of infarct-related artery, preservation of ventricular function, and improved survival after thrombolytic therapy for acute myocardial infarction. An increased infusion rate of rt-PA has been shown to result in faster thrombolysis and a high patency rate of occluded vessel in myocardial infarction. Therefore, we evaluated the effect of simplified triple bolus injection of rt-PA on early patency of infarct-related artery and evaluated safety and efficacy of triple bolus injection. METHOD: Patients with acute myocardial infarction presenting up to 6 hour from the onset of chest pain were recruited for the study. Aspring(100-200mg) was given immediately. Total dose for 1.5mg/kg of rt-PA(minimum 75mg, maximum 100mg) was administered as triple bolus intravenous injections. The half of total dose was injected initially, the quarter of total dose was injected at 10 minutes after 1st injection and the remainder was injected at 40 minutes after 1st injection. Five thousand units of heparin was given and 1,000-1,500unit/hr was given continuously. Coronary angiogram was performed at 60 minutes and 7-10 days after the first bolus injection. RESULTS: At 60 minutes, eleven of fourteen patients (78.6%) showed TMI grade-3 of patency in infarct-related coronary artery. There were two patients of hemorrhagic complications. One patient developed cerebellar hemorrhage at third day after rt-PA injection, and the other developed bleeding at femoral sheath site. There was no in-hospital mortality and reinfarction. CONCLUSION: In patients with acute myocardial infarction, the simplified triple bolus injection of rt-PA is associated with high early patency(TMI grade-3) in infarct-related coronary artery, with low risk of major bleeding comlications comparable to other studies.
