A Case of Mucosal Necrosis of the Stomach after Endoscopic Injection Therapy with Hypertonic Saline-Epinephrine (HS-E) for a Bleeding Peptic Ulcer with an Exposed Vessel / 대한소화기내시경학회지

Peptic ulcer bleeding is a frequent cause of upper G-I bleeding. Endoscopic injection therapy with hypertonic saline-epinephrine (HS-E) is a cost-effective and widely used therapy for hemostasis; however, 1~3% of patients experience bleeding or perforation. A 70 year-old male patient was admitted with melena and hematemesis. An endoscopy on admission showed the presence of a 1 cm- sized well-demarcated ulcer with pulsatile bleeding at the lesser curvature of the distal antrum. Approximately 28 mL of HS-E solution was injected around the exposed vessel. Follow-up endoscopy performed 7 days later showed the presence of a 2 cm-sized newly developed mucosa necrosis at the lesser curvature of the pyloric channel, which was caused by ischemic necrosis of the gastric mucosa after HS-E injection. Endoscopic injection therapy with HS-E solution is a relatively safe technique, but mucosa necrosis can occur with the use of a dose of HS-E that is considered safe. We report a case of gastric mucosa necrosis following endoscopic HS-E injection therapy of a bleeding peptic ulcer.

Comparison of Hemostatic Effects between a Combination Therapy Including Endoscopic Injection Therapy and Omeprazole and a Single Intravenous Omeprazole Therapy in Patients with Bleeding Peptic Ulcers / 대한소화기내시경학회지

BACKGROUND/AIMS: This study was performed to test whether there is some difference between combined endoscopic therapy with PPI infusion and intravenous PPI therapy alone. METHODS: A total of seventy-three high-risk patients with ulcer bleeding and non-bleeding visible vessels or fresh adherent clots resistant to irrigation were randomized to medical therapy [intravenous omeprazole therapy alone: 40 mg IV per day for 3~5 days] or to endoscopic combination therapy [endoscopic epinephrine (1 : 10,000 in normal saline) or ethanol injection followed by intravenous omeprazole infusion]. RESULTS: Patients were similar at study entry. Ulcer bleeding recurred in two patients who received combined endoscopic therapy (2/35, 5.7%) while ulcer bleeding recurred in ten patients who received intravenous omeprazole alone (10/38, 26.3%) (p < 0.05). Two patients (2/35, 5.7%) in the combined therapy group and five patients (5/38, 13.2%) in the omeprazole infusion alone group had surgery for intractable bleeding (p=0.281). One patient in each group died within the hospital stays (p=0.953). CONCLUSIONS: The combination of endoscopic injection therapy with omeprazole infusion is superior to omeprazole infusion alone for preventing recurrent bleeding from ulcers with nonbleeding visible vessels or adherent clots.

A Case of Bleeding Jejunal Tuberculosis Diagnosed with Intraoperative Endoscopy / 대한소화기내시경학회지

Tuberculosis is a multi-organ disease. The incidence of pulmonary tuberculosis is declining due to improvement in public health, vaccination and the development of anti-tuberculosis medication, but extrapulmonary tuberculosis has become more common, especially in immuno-compromised individuals, AIDS patients and immigrants to western worlds. Gastrointestinal tuberculosis continues to give rise to diagnostic and therapeutic challenges. The jejunal tuberculosis is uncommon and presents a difficult diagnostic problem. Bleeding jejunal tuberculosis is a very rare source of lower gastrointestinal bleeding. We have recently experienced a case of a jejunal tuberculosis which was proven to be a source of gastrointestinal bleeding by intraoperative endoscopy and was confirmed by surgical exploration. This report summarized our experience and review of literature.

The Hemostatic Effect and Prognosis of Endoscopic Ethanol Injection in Bleeding Peptic Ulcer / 대한소화기내시경학회지

BACKGROUND AND AIMS: Endoscopic injection therapy improves the outcome in bleeding peptic ulcer, but the optimum regimen is unknown. Although endoscopic injection therapy is effective in controlling initial hemorrhage from a peptic ulcer, between 10% to 30% of patients suffer rebleeding. The aim of this study was to evaluate the initial and ultimate success rate of hemostasis, the rebleeding rate, hospital stay (days), and the emergency operation rate in patients who had undergone endoscopic ethanol injection for bleeding peptic ulcer. METHODS: Thirty nine patients presented with active bleeding (spurting), visible vessels, or blood clots on endoscopic findings were given an endoscopic ethanol injection with a total of 1.0-3.0 ml of ethanol. The initial and ultimate success rate of hemostasis, rebleeding rate, and emergency operation rate after the endoscopic injection was evaluated. RESULTS: 1) The initial success of hemostasis was 38/39 (97.4%). 2) The rebleeding rate after ethanol injection was 8/39 (20.5%). 3) The success rate of the second trial of ethanol injection was 3/8 (37.8%). 4) Emergency operations were conducted in5/39 (12.8%). 5) The ultimate success rate of hemostasis was 34/39 (87.2%). 6) There were no mortalities [0/39 (0%)] related to the ethanol injections and bleeding peptic ulcers. 7) There were no complications [0/39 (0%)] related to the ethanol injections. 8) The mean duration of hospitalization was 9.5 4.5 days. CONCLUSIONS: Endoscopic ethanol injection in the treatment of bleeding peptic ulcers was as effective and safe as any other injection or mechanical hemostatic method. Further prospective studies or endoscopic trials for hemostasis are needed to reduce the rebleeding rate and emergency operation rate of bleeding peptic ulcer.

Clinical Trial of Endoscopic Botulinum Toxin Injection for the Treatment of Primary Achalasia / 대한소화기내시경학회지

Primary achalasia is a disorder of swallowing in which the lower esophageal sphincter fails to relax. Traditional treatment methods are balloon dilatation and myotomy, but these methods have critical complications and even fatal including esophageal perforation, gastroesophageal reflux, and continuing dysphagia. Botulinum toxin, which has been used for dystonias of skeletal muscles, is presented as a new alternative treatment method for achalasia, aimed to lowering of LES pressure by Pasricha et al. They also reported that endoscopic botulinum toxin injection into LES was effective, safe, and simple method without any significant complication. We report 7 cases of primary achalasia treated with endoscopic botulinum toxin injection, who showed clinical improvement without any complication. We compared results of pre-treatment with those of post-treatment using botulinum toxin in the aspects of clinical, radiological, manometrical recording in these cases. Symptomatic improvement was shown in 4 cases(57.1%), symptom score was decreased from 7.43+/-0.53 to 4.43+/-2.51(p=0.03), The luminal diameter at esophagogastric junction increased from a mean of 3.21+/-0,99 mm to 5.14+/-0.90 mm (p=0.015), and luminal diameter at esophageal body decreased from a mean of 40.29+/-19.37 mm to 32.71+/-15.45 mm (p=0.015). In follow up manometric recording, peristaltic waves at the body were recovered in 2 cases(28.6%), gastroesophageal pressure gradient(AP) was non-significantly decreased from 6.30+/-4.0 mmHg to 3.12+/-4.47 mmHg (p=0.45). One patient complained of transient chest pain within one hour after the botulinum toxin injection, but she did not need any medication. We concluded that botulinum injection was a simple, safe, and effective therapeutic method for primary achalasia, even though further evaluatian should be performed in the much more cases and the results of long term follow-up, and cost-effectiveness of this method.

Comparison of Endoscopic Injection with Hypertonic Saline-Epinephrine(HSE) and Absolute Ethanol for Bleeding Peptic Ulcers / 대한소화기내시경학회지

BACKGROUND/AIMS: The endoscopic injection therapy with hypertonic saline-epinephrine(HSE) and absolute ethanol are the most widely and easily used procedure in the management of patients with bleeding peptic ulcers. We performed a prospective, randomized trial to compare the hemostatic efficacy between HSE and absolute ethanol injection therapy. METHODS: During the period of 1993 to 1996, 60 patients who were identified as active bleeding or visible vessel were enrolled for this trial. The 60 patients were randomly divided into two groups(HSE group, 30 cases: ethhnol group, 30 cases). We performed endoscopic injection therapy with 3% saline and 1:10,000 epinephrine solution in HSE group, and with 99.5% absolute ethanol in ethanol group. The two groups were matched for sex, age, site of bleeding, endoscopic findings, initial hemoglobin, and concomitant illness at randomization. RESULTS: Bleeding was initially controlled in 21(70%) of the HSE group and in 29(96.7%) of the ethanol group(p < 0.05). Rebleeding occurred in 4(19%) of the HSE group and in 2(6.9%) of the ethanol group(p < 0.1). The ethanl group achieved a better hemostatic effect for spurting hemorrhage(3/13 vs 9/10, p < 0.05). The emergent operations were undergone in 10(33.3%) and 2(6.7%) for HSE group and ethanol group respectively(p < 0.01). The stay in hospital were less than in ethanol group(mean 9.5 vs 16.3, p < 0.01). The death were noticed in 6 cases(20%) in HSE group and 1 case(3.3%) in ethanol group(p < 0.05). CONCLUSIONS: This study shows that absolute ethanol injection is more efficaceous and better satisfactory method in peptic ulcer bleeding.

Comparison of Hemostatic Effect of Endoscopic Injection with Fibrin Glue (FG) and Hypertonic Saline - epinephrine (HSE) for Peptic Ulcer Bleeding: A prospective randomized trial / 대한소화기내시경학회지

Endoscopic injection therapy using various different agents(ethanol, polidocanol, epinephrine with and without hypertonic saline, etc.) is considered as the least expensive and effective technique to obtain hemostasis in peptic ulcer bleeding, however most of these agents induce tissue necrosis or degeneration. Theoretically the injection of fibrin glue in peptic ulcer bleeding may be safer than that of other agents, however, to date, there have been no data from randomized clinical trials on the comparison of the efficacies between these agents. To compare the hemostatic efficacy between FG[Beriplast P, Behring, Germany] and HSE[3% saline and epinephrine(1: 10,000)], we conducted a prospective, randomized, clinical trial among one hundred twenty-seven patients with peptic ulcer bleeding from March, 1992 to December, 1993 and in whom a visible vessel or active bleeding was identified.

Hemostatic Effect of Endoscopic Local Injection of Hypertonic Saline - Epinephrine Solution in Peptic Ulcer Bleeding / 대한소화기내시경학회지

To date several agents have been used to achieve hemostasis in patients with bleeding peptic ulcers using endoscopic sclerotherapy techniques. In this study, the efficacy of endoscopic local injections of hypertonie saline-epinephrine(HS-E) solution, consisting of 9 volume of 3% sodium chloride and 1 volume of 1: 1000 epinephrine, on the base of the ulcer around bleeding vessel was assessed. During the period between April 1989 and July l992, 127 patients were admitted to the study. Ninety-six of these patients underwent endoscopic treatmeat(endoscopic treatment group), while the other 31 cases received conservative treatment only(conservative treatment group). (continue...)
