JOURNAL FREE ACCESSIn Japan, we sometimes find AIDS-related gastrointestinal diseases when performing endoscopic examinations. At Tokyo Metropolitan Komagome General Hospital, we performed over 170 upper endoscopic examinations and over 47 colonoscopic examinationsfrom 1989 to 1997. The AIDS-related lesions usually have characteristic endoscopic findings. Candida esophagitis appears as thick white plaques on the esophageal wall. The ulcerative lesions caused by Cytomegalovirus in the esophagus and colon resemble a punched out ulcer withno edema around it and usually no slough at the bottom. Kaposi's rarcoma in the stomach, duodenum and colon appears in the form of submucosal nodules with varying degrees ofredness. After examining an HIV-positive patient, it is necessary to prevent secondary infection. The Scope must be washed by the machine, soaking it in a 2% glutaraldehyde solution far at least 45 minutes, the same as with HBV-positive patients.View full abstractDownload PDF (5498K) -

JOURNAL FREE ACCESSEndoscopic diagnosis of gastric microcancer has been studied with the historical datafrom endoscopic findings of 97 1esions of 200 1esions which included pathologically foundlesions on the surgical specimens. The endoscopic findings were classified into two maintypes with the red cclcred (differentiated ca.) and the white colced (undifferentiated ca.) types. In order to diagnose more gastric microcancers, these two types of the endoscopicfindings must be first detected and the first aiming biopsy from the center of these lesionsmust be most important to be obtained after a magnifing endoscopy and a dye endoscopy. An endoscopically detectable limitation of the microcancer seemed to be 2 to 3mm in thelongest dimension. An incidence of undifferentiated carcinoma of all diagnosed microcancers was 13.4%in the very low rate and sm invasion was confirmed in 2.0%. The reasonsof the low incidence of the undifferentiated carcinoma considered to be due to a difficultyto the endoscopic detection, a poor chance to the endoscopic examination on the youngerpeople than 50 years old and the pathologically low rate of the pure undifferentiated carcinoma. The most of the microcancers might develop to the advanced cancer but a fewmicrocancers might be excluded or destroyed by many factors. The future of the endos-copic diagnosis of the gastric microcancer will be much develop with the further improve-meat of endascopic instrument and technique.View full abstractDownload PDF (5618K) -

JOURNAL FREE ACCESSTwo hundred and ninety five patients with submucosal cancer of the colon and rectumwere studied to evaluate the results of endscopie mucosectomy. Among 197 patientsreceived endoscopic mucosectomy as an initial treatrnent, 106 had sml invasion and 81 hadsm massive invasion which was confirmed by histopathological examination after endoscopic resection. Of the 106 patiensts with sml invasion, 12 received additional bowelresection but no patient had lymph node metastasis. Of the 81 patients with sm massiveinvasion, 55 received additional hflwel resection, including 19 patients with positive marginand 36 of 62 patients with negative margin. Of the 19 patients who received additionalsurgical resection due to positive margin, 5 had residual cancer, one had lymph nodemetastasis, and one had hepatic metastasis postoperatively. Of the 36 patients whoreceived additional surgical resection without positive margin, only one patient had Iymphnode metastasis. Among 108 patients who received bowel resection as an initial treatment, 12 patients had lymph node metastasis. Eleven of the 12 patients revealed both massiveinvasion deeper than sm2 and positive lymphatic invasion. Those data show that endo-scopic mucosectomy can provide curative treatment for patients who have negative marginafter endoscopic mucosectomy for submucosal cancer and additional surgical resection isrequired only for patients who had both massive submucosal invasion and positive lymphatic invasion.View full abstractDownload PDF (2594K) -

JOURNAL FREE ACCESSAn 80-year-old woman with esophagogastric anastomotic stricture following anesophagectomy had undergone 12 sessions of endoscopic balloon dilatation and 21 sessionsof bougienase. However, because these treatments were of only temporary benefit, a selfexpandable metal stmt eras inserted an April 1996. As a result, the stricture vvas relivedand it was possible to pass an endoscope through the area. The patient also could Intakerice gruel. In July 1996, however, the stricture reoccurred due to the growth of granulationtissue inside the stmt. Therefere, we performed 7 sessions of ethanel injection therapy, which was successful in removing the granulation tissue and resulted in a remarkableimprovement. when the granulation tissue regrew, eve eventually inserted a coveredexpandable metal stmt, an improved model covered with a polyurethane membrane, in astmt in stmt manner, after several sessions of ethanol injection therapy and balloon dilatation and were able to make it possible for the patient to eat erally.View full abstractDownload PDF (2456K) -

JOURNAL FREE ACCESSAcase of chronic afferent loop syndrome treated by endoscopic balloon dilatation wasreported. A 80-year-old female was admitted to our hospital because of sudden onset ofepigastralgia accompanied by bilious vomiting.5hc had a past history of partial gastrectomy with reconstruction of Billoth II method. Narrowing of orifice at afferent loopwith the scar of ulcer has been demonstrated by follow up endoscapic examinations. Ulcerwas detected 3 years previously and treated with H2-hlocker. A diagnosis of chronicafferent loop syndrome was made from the finding of CT demonstrating a dilated afferentloop and endoscopie findings. Symptoms improved by endoscopic treatment with balloondilatator. No recurrence of symptoms has occurred since the endoscopic treatment vasperformed.View full abstractDownload PDF (2850K) -

JOURNAL FREE ACCESSA 70-year-old woman visited us because of increasing exerticnal dyspnea. Physicalexamination revealed anemic conjunctiva and an emergent blood examination confirmedan extremely low hemogulohin level, 4.6g/dl. She was hospitalized for further evaluation.Atest for occult blood in the feces was positive. Upper gastrointestinal endoscapy revealedlongitudinal red areas radiating to the pyrolic ring in the whole antrum, and a diagnosis ofgastric antral vascular ectasia was made. As treatment, mucosal coagulation therapy byYag laser under gastrofiberscope procedure was instituted. The treatment was repeatedlyperformed at one to two weeks interval. After the sixth session, red mucosal areas almostdisappeared and the hemogloin level was normalized. Any adverse effect did not developedduring the treatment period. Endoscapic mucosal caagulatian using Yag laser was consid-Bred as a useful and safe treatment for the gastric antral vascular ectasia.View full abstractDownload PDF (4337K) -

JOURNAL FREE ACCESSWe report a rare case of malignant fibrous histiocytoma(MFH)with gastric metastaxis. A 64-year-old male with MFH of the right knee treated in our hospital had upperabdominal discomfort. Upper gastrointestinal series and endoscopic examination revealedsubmucosal tumor with shallow depression at the greater curvature of the posterior side ofthe gastric antrum. Endoscopic ultrasonography showed hypoechoic mass in the faurthlayer. Gastric metastasis of MFH was suspected by biopsy specimen. Surgical resectionwas performed because of no evidence of the other distant metastasis. We histologicallydiagnosed this lesion as MFH metastatizing to the stomach, 3.3x3.ocm in size, depth ofinvasion was subserosa with no lymph node metastasis.View full abstractDownload PDF (5577K) -

JOURNAL FREE ACCESSA 74-year-old woman admitted to our hospital due to right lower abdominal pain, constipation and rapid growing abdominal mass. High grade fever, tenderness on the lowerabdomen, severe inflammatory sign on laboratory data were observed on admission.Abdominal ultrasonography and CT scan showed a solid mass at a size of 15×7×7cmcompressing the ascending colon, suggesting pericecal abscess. High fever alleviated oneweek after antibiotics therapy, and the mass size reduced gradually. Colonoscopy andbarium enema examination reveaied smail round elevation at the orifice of the vermiformappendix and disappearance of extracolonic compression by the mass. From these findings, appendiceal tumor and pericecal abscess with ileocecal displacernent was stronglysuspected. On laparotomy, the appendix was located retrocecally on the cecum, andstrongly adhered to the ascending colon. Right hemicolectomy was performed. Inside theswollen appendix, there was mucinous alkaline fluid in a volume of 2ml. The pathologicaldiagnosis was mucinons cystadenoma of the vermiform appendix accompanied by localizedpseudomyxoma. We herein reported the rare case of mucinous cystadenoma of thevermiform appendix with inflammatory mass witch was the dominant sign in the clinicalcourse.View full abstractDownload PDF (5981K) -

JOURNAL FREE ACCESSA case of colon hemangioma treated by strip biopsy is reported. A 61-year-old womanvisited our hospital with a complaint of bloody steal. Golenoscopy revealed a dark blue submucosal tumor 15mm in diameter in the sigmoid colon. Endoscopic ultrasonography (EUS) with intraductal catheter probe (20MHz) demonstrated the tumor lesion in thecolanic third Iayer with heterogeneous internal echoes. The patient did not want toundergo surgery and thus, endoscopic mucosal resection was performed. The procedurewas performed successfully without complication. The histological diagnosis of the tumorwas cavernous hemangioma. EU5 is thought to be useful in the localization of colonhemangio7na, and we consider that colon hemangioma can be possibly treated by endoscopic resection.View full abstractDownload PDF (3092K) -

JOURNAL FREE ACCESSA 78-year-old man with end stage gastric cancer had dower abdommbal pain and hematochezia after starting steroid therapy. Golonoscopy showed multiple large deep ulcers from the rectum to the sigmoid colon. He was diagnosed to have cytomegalovirus (CMV) colitis with many cytomegalic inclusion bodies and positive stains with immunohistochemical technique using monoclonal antibody to CMV in biopsy specimens obtained from the base of the ulcer. CMV colitis demonstrated by colonoscopic examination is still rare in Japan, and its colonoscopic appearance may be similar to that of amebic colitis, as shown in our cast. Differential diagnosis using histology and serology is thus considered to be necessary.View full abstractDownload PDF (2994K) -

JOURNAL FREE ACCESSA 84-year-old man was admitted to our hospital in December 1993 for the purpose of further examination of recurrent cholangitis. He had undergone Billroth II gastrectomy for gastric cancer at the age of 65 and pancreaticoduodenectomy in January 1993 for pancreatic head cancer. Endoscopic retrograde cholangiography showed a stricture at the bilioentelic anastomosis and a multiple bile duct stones. Thus, it was thought to he difficult to extract stares in a single session, and we performed balloon dilation of the anastomatic stricture, placed 7Fr, double pig-tail stmt in the bile duct for the purpose of preventing from impaction of the stone and maintaining patency of the duct. After 8 months, August 1894, he developed cholangitis due to stent occlusion. The cholangiography showed little change with the stones and the occluded scent was exchanged. Thereafter, the per oral administration of ursodeoxycholic acid (UDCA) was added to the biliary endoprosthesis. Six months later, he developed cholangitis again and we exchanged the stent. Cholangiography at that tirne showed a marked decrease in the stone number and size, only one stone was remained. Finally, 12 months later, September 1995, we found the migrated tent from the bile duct, the dilated anastomosis and disappearance of the stone. Since then, we have been treated with only UDCA and he has been in good condition. The combination therapy of endoscopic biliary drainage and UDCA was easily and considered to be effective for elder or poor risk patients with nonextractable common bile duct stones.View full abstractDownload PDF (3758K) -

JOURNAL FREE ACCESSWe investigated the utility and problems with three-dimensional (3D) intraductal ultrasonography (IDUS), compared with usual IDUS for four cases of mucin producing tumor of the pancreas. A 3D-IDUS imaging system with ultrasonic probes was employed by transpapillary approach. Three of the tumors were located in the head region of the pancreas and the remaining one case in the head to tail region. In all cases, assessment of tumor extension, evaluation of mural nodules and the volume measurement of cystic lesions could be easily performed. The results confirmed that the diagnostic ability of 3D-IOUS is superior to that of usual IDUS, but suggested that suitable subjects may be limited. Future improvement in the instrumentation is, however, to be anticipated which will allow more widespread application.View full abstractDownload PDF (6108K)
