JOURNAL FREE ACCESSOcclusio:n of the biliary stent which is caused by biliary slud.ge containing bacteriabiofilrn is a major problern of endoscopic retrograde biliary drainage(ERBD). The authorperformed an in vitro study on the potential prophylaxis of biliary stent occlusion by silvercontai:ning stent. Conventional 10 Fr polyethylene stent as control and 10Fr silver containing stent were soaked in human bile obtained from nasobiliary catheter in 29 patients withobstructive j aundice, and the inner surface of the stems were examined serially by scanningelectron microscopy. In the 1.5wt%silver containing stent group, after 11.6days of meansoaking time, bacteria was scarcely attached in four of nineteen cases(21.1%), andbacteria and amorphous material were reduced in thirteen cases(68.4%)as compared withcontrol, The silver containing stent tended to inhibit the growth of bacteria and thisinhibitory effect depended on the constituent ratio of the silver. Released level of silverfrom new stent in the bile was minimal and thought to be harrnless to humans.View full abstractDownload PDF (7752K) -

JOURNAL FREE ACCESSWe collated 19, 722 cases who had been examined by gastroscope in our hospltal from 1984 to 1989 with the cancer registry in Fukui Prefecture.188 false negative gastric cancerpatients were extracted. The false negative ratio in endoscopic examination was 5.5% inlyear from the last examination to diagnosis, 11.5%in 2 years and 15.6%in 3 years. The false negative ratio was not associated. with sex, age, type of endoscope, locationof cancer or histolegical type. Put the incidence of the advanced cancer in the falsenegative cases was significantly associated with the location and the histological type. The review of the previous gastroendoscopic films revealed that the inadequateexaminations were done mare often in males than females, and that no lesions or minimalchanges were foand more often in females than males, significantly.The proportion of inadequate examination was significantly higher in the patients whose cancer occupied thefundus, the remanant stomach or the angulus than the body or the antrum. The definitelesions were found more often in the cases whose cancer occupied the body than the anguluor the antrum.View full abstractDownload PDF (1249K) -

JOURNAL FREE ACCESSWe studied 10 cases of multiple early gastric cancer among endoscpically resected (ER) 118 early gastric cancer from 1985 to 1993. Incidence of multiple early gastric cancer cases are 8.5%(synchronous 5.9%, metachronous 2.6%). In metachronous multiple lesions, two cases were detected within 2 years and one case was detected 5 years after ER. As to themain lesions, all histological types were differentiated type, macroscopic types were almostelevated type and their location were almost in the antrum. Concerning the main andassociated lesions, both of the macroscopic types were almost the same type and both of them were almost differentiated type. It should be carefully minded that high risk gastric mucosa is remained after ER. Therefore, strict fallow-up is necessary far multiple cancerous lesions.View full abstractDownload PDF (539K) -

JOURNAL FREE ACCESSAcase of hemorrhagic Dieulafoy's ulcer of the posterior portion of the duodenum forwhich endoscopic ethanol injection was useful was reported. Permanent hemostasis wasachieved by the local injection of pure ethanol. A 58-year-old man was admitted to our hospital because of sepsis with urinary tractinfection on Jan.31.1994. Antibiotics and non-steroidal anti-inflammatory dru.gs werestarted. Progressing anemia with tarry stool was noticed on Feb. 3, and emergentendoscopy revealed multiple gastric erosions. Bleeding from acute gastric mucosal lesions(AGML)was suggested. Treatment with anti-ulcer agents did not improve tarry stool. OnFeb.10 hematoemesis and melena occured and side-viewing endoscopy revealed healinggastric erosions and a small ulcer of 3mrn in diarneter accompanied with a:naked vessel anthe opposite and anal side of the superior duodenal angle, namely post-bulbar Dieulafoy'sulcer, in which ethanol injection was successfully performed. There are several reports ofpost-bulbar Dieulafoy's ulcer and this is one of the rare cases in which endoscopicprocedure was useful for hemostasis.View full abstractDownload PDF (1685K) -

JOURNAL FREE ACCESSTo diagnose quantitatively the flat type neoplasm of large intestine, we studied pitpattern by computer analysis of stereomicroscopical and histological image. This studyassessed the the characteris of pit pattern, with parameters (maximum diameter, circumference, area field, roundness and convexity) by computer image analysis after extatraction of pit pattern in 8 eases with normal large intestine and 34 cases with flat typeneoplasm of large intestine (12 cases of tubular adenoma with moderately atypia, 13 casesof tubular adenoma with severe atypia and g cases of cancer), and evaluated the correlationbetween stereomicroscopical and histological image in 30 cases (4 cases of normal largeintestine, 11 cases of tubular adenoma with moderate atypia, 10 cases of tubular adenomawith severe atypia and 4 cases of cancer) . The results revealed that ail the parametersshowed significant difference respectively between moderately atypia and cancer (P < 0.05) .Moreover circumference and convexity were significantly different between severe atypiaand cancer (p < 0.05), respectively, and there were correlation between stereomicroscopicaland hystologieal imagos. This results supported tho possibility of quantitative diagnosis.View full abstractDownload PDF (1881K) -

JOURNAL FREE ACCESSThe purpose of this study is to examine the clinical usefulness and the problems ofendoscopic approach to pancreatic diseases by sheath method.
The subjects are 139 cases with pancreatic diseases (31 cancer, 2metastatic cancer, 55chronic pancreatitis, 42 mucin-producing tumor, 4 islet cell tumor, 2serous cyst adenoma, 1teratoma, 1solid cystic turnor, 1fatty change) for intraductal exarnination (intraductalultrasonography, peroral pancreatoscopy and pancreatic biopsy) and in 5 cases withpancreatolithiasis for intraductal treatment. We examined the clinical usefulness andproblems of the sheath method in comparison with the non-sheath method.
This sheath methed is useful for the improvement of the endurance of these instruments, the decrease of the number of times of examination, the shortening of examinationtime and the effect of washing out the pancreatic duct in the treatment of the pancreatciithiasis through pancreatoscopy. The problems of this method are that speciments obtainedby the pancreatic biopsy are small for the diagnosis (of the pancreatic diseases) and thatit is difficult to insert the instruments into the pancreatic duct when the sheath is bentduring the examination and the treatment. The acute pancreatitis as one complication isseen in 2 of 117 cases of sheath method (1.7%), one of 22 cases of non-sheath method (4.5%) in the examinations and no camplicataon in the treatment of pancreatelithiasis.
In conclusion, the sheath method could allow us the intraductal examinations andtreatment of the pancreatic diseases more easily.View full abstractDownload PDF (2991K) -

JOURNAL FREE ACCESSWe treated 2 cases of esophageal obstruction due to esophageal squamous cell carcinoma with expandable metallic stems (EMS;12mm in diameter and 15mm in length) covered with silicon. one case was 59-year-old man who was treated with 4 EMS for esophageal obstruction. EMS was expanded 12mm in diameter within one week after its replacement and dysphagia was improved. However, the growth of esophageal cancer at the proximal end of EMS caused recurrent dysphagia 2 months after its replacement and then the esaphago-medzastlnal fistula developed one month later. Therefare, we placed EMS in EMS to palliate esophageal obstruction and covered the fistula. He could eat food until he died from aspiration pneumonia due to recurrent nerve palsy. Another case was a 63 year-old man wha was treated for esaphageal obstructian with EMS and could eat rice porridge. However, he died from aspiration pneumonia due to recurrent nerve palsy at 1 month after EIVIS repiacement. In conclusion, silicon-covered EMS can provide good palliation in cases of inoperable, malignant esophageal obstructions.View full abstractDownload PDF (8749K) -

JOURNAL FREE ACCESSWe report two cases of gastric reactive lymphoreticular hyperplasia(G-RLH)whichremarkably improved by the eradication therapy of Helicabacter pylori (Hp). Thoughendoscopic abnormal findings were relatively mild in both cases, severe massive infiltrationof mononuclear cells was observed in biopsy specimens, and superficial spreading type ofgastric malignant lymphflma could nat be ruled aut. In each case, B-cell monoclonality ininfiltrated mononuclear cells could not be recognized by the immunohistological stainingnor by the molecular biological examination with polyrnerase chain reaction to immunoglobulin heavy chain. They were treated for Hp after confirmation of Hp-infection. Aftersuccessful eradication of Hp, endoscopic and histological findings improved remarkably.From these clinical courses, the infiltration of these mononuclear cell was thought to becaused by the reaction to chronic Hp infection. When a differentiation between G-RLH and gastric malignant lymphoma is difficultand manaclanality of infiltrated mononuclear cells is hard to by proved, the eradicationtherapy for Hp should be performed.View full abstractDownload PDF (8301K) -

JOURNAL FREE ACCESSA 19-year-woman with a 2-year history of bronchial asthma visited our hospital because of epigastric pain and nausea. Esophagagastroduodenoscopy revealed multiple white plaques on the esophageal mucosa. Hematological examination showed leukocytasis and eosinophilia in the peripheral blood. Neurological examination an admission disclosed mononeuritis in bilateral upper extremities. Two weeks later, she had hematochezia of sudden onset, and colonoscopic examination revealed multiple shallow ulcers zn the sigmold and descending colon. One month later, puzpuric lesions appeared on the face and lower extremities. Siapsy specimens of the skin showed necrotizing angitis and extravascular granulations with rnarked eosinophilic infiltration. We diagnosed this case as Churg-Strauss Syndrome on the basis of the clinical and pathological findings. Churg-Strauss syndrome is a very rare disease, but gastrointestinal disorders often affect the prognosis far the patient's life.View full abstractDownload PDF (4279K) -

JOURNAL FREE ACCESSA 65-year-old man underwent a colonoscopic examination because of a positiveimmunological occult blood test. After 5 hours of the examination, he complained of mildlower abdominal pain with fever. Two days later, X ray studies demonstrated intraperitoneal free air, retraperitonral gas and subcutaneous emphysema from the scrotum to theneck. Conservative treatments with parenteral nutrition, administration of antibiotics andhyperbaric oxygen were taken. Chest and abdominal computed tomograms 7 days afteradmission showed almost resolution of the air.An enema study with contrast medium gdays after admission revealed mild stenosis from the sigmoid colon to sigmoido-descendingcolon junction without extravasation. The patient has been well after discharge. This isthe first repart, in which intraperitaneal free air, retroperitaneal gas and subcutaneousemphysema were occured at the time of a colon.oscopic examination. Hyperbaric oxygentherapy reduced retroperitoneal gas and subcutaneous emphysema, improved oxygendelivery to organs and decreased the incidence of endotoxemia.View full abstractDownload PDF (4573K) -
