JOURNAL FREE ACCESSNewly developed anorectal ultrasonographic probe(the rectal probe)for the anorectal lesions was examined and evaluated it's efficacy. Specification of this rectal probe, produced by OLYMPUS Optical co., is mechanical-radial type ultrasonographic probe which is 15cm in length and 12mm in diameter stick type probe with a frequancy of 7.5 or 12MHz and is provided a 360-degree scanning angle. This probe is able to connect to the EUM30 and is equipped water pouring system and suction mechanism. Subjects were 40 cases of anorcctal lesions, composed of 14 cases with rectal tumor(4 adenomas, 3 early cancers, 7 advanced cancers), 1 with metastatic rectal tumor, 3 with submucosal tumor, 2 with operated colonic cancer, 5 with ovarian tumor, 14 with rectal varices and hemorrhoids, 1 with rectal mucasal proraps syndrome. After endoscopic observation, the lesions were examined by the ultrasonographic probe with water-filling method. The rectal probe was examined by water filling method or balloon method. All cases could be examined easely and safely. Appropriate image for accurate diagnoses were obtained in 35 eases among of 40 (87.5%). 2 cases could not obtain good imagesby using the rectal probe, because these lesions were too small to find out without endoscopic systems. (Each diameter was less than 3mm.) However, most of the Iesions were clealy demonstrated by using the rectal probs. Therefore, this rectal probe is useful in diagnose the anorectal lesions of which diagnosis were insufficient with the use of ultrasonographic probealone.View full abstractDownload PDF (12020K) -

JOURNAL FREE ACCESSA 71-year-old man presenting lower esophageal stenosis due to inoperable esophageal cancer was treated by self-expandable metallic stent(SEMS)and chemotherapy by CDDP and 5FU using durable portable infuser pump at an outpatient clinic. As a result, he could do oral intake far 264 days and survived 282 days after SEMS insertion. wring treatments, bath ends of the SEMS were narrowed by granulation tissue growth, and upper esophagus was restrictedby intramural metastasis. However, both events were solved by balloon bouginage, argon plasma coagulation therapy and re-stenting of the SEMS. For the quality of life of the patient with inoperable advanced esophageal cancer, an early indication of SEMS and outpatient-clinic chemotherapy can he possihie alternative against the eonventienal chemoradiotherapies with a sufficient informed consent.View full abstractDownload PDF (7076K) -

JOURNAL FREE ACCESSA 68-year-old-woman was admitted to our hospital for the follow-up examination of multiple hyperplastic polyps in the gastric remnant. Endoscopic findings showed a pedunculated lesion, approximately 2 cm in size on the greater curvature of the upper body of the stomach. The biopsy specimens revealed group IV and endoscopic mucosal resection was performed. Histological examination showed well differentiated adenocarcinoma at the top of the lesion. Immunohistochemical study (p53, Ki-67) showed that the other areas of the lesion consisted of hyperplastic and dysplastic areas, suggesting that focal cancer in a hyperplastic polyp developed from dysplasia. Focal cancerization in gastric hyperplastic polyp is rare. However, as to hyperplastic polyps in gastric remnant, we should be alert to the change in size and the features of the surface.View full abstractDownload PDF (8867K) -

JOURNAL FREE ACCESSA 26-year-old man had acute abdomen and underwent emergency operation in May 1997. The small intestine was perforated about 30cm proximal to the end of ileum. Partial resection of the small intestine with end-to-end anastomosis was performed. The diagnosis of Crohn's disease was made. In December 1999 when he was admitted to the hospital for the treatment of perianal abscess, the patient developed nausea. Barium study showed an heal stricture, 1cm in length. Endoscopic balloon dilation using Microvasive Regiflex TTS® balloon catheter for the large intestine (outer diameter 12mm and 15mm) was performed 4 times in 3 months. Since then, there have been no signs to suggest the digestive tract passage disorder. There is no definite view on the long-term effect of endoscopic balloon dilation. However, we think that endoscopic dilation seems to be a valuable therapeutic approach for small intestinal stenosis associated with Crohn's disease, which should be attempted to prevent repeated surgical operation.View full abstractDownload PDF (6963K) -

JOURNAL FREE ACCESSAn 85-year-old woman admitted to our hospital with nausea and persistent fever, and had a sudden onset of anal bleeding 8 days after the admission. The colonoscopy revealed a well -demarcated open (punched out) ulcer in the sigmoid colon and ischemic mucosal changes in the adjacent colonic segment. Because of the resistance to the conservative therapy, she underwent sigmoidectomy on day 15 after the admission. "The histological finding was compatible with a simple ulcer, characterized by a deep ulceration accompanied with nonspecific inflammation. Although the simple ulcer is a well-known disorder occurring in the ileo-cecal region, the disease in the sigmoid colon is rare, and to our knowledge, only 7 cases have been published in the Japanese literature. The etiology of this disease, occurring preferentially in the agedpatients (26 to 85) and not accompanied with Behcet disease, suggests its unique pathogenesis. Early clinical suspicion combined with surgical management is mandatory in preventing serious morbidity of perforation or penetration accompanied with simple ulceration in the sigmoid colon.View full abstractDownload PDF (6408K) -

JOURNAL FREE ACCESSA 76-year-old man without an apparent history of chronic pancreatitis was admitted because of massive ascites. The pancreas was normal in abdominal CT scan but pancreatic enzymes in ascites and serum were elevated. The patient was treated by the conservative therapy, and endoscopic retrograde pancreatography (ERP) which performed after ascites disappeared showed the small cystic lesion with leakage of contrast medium into the peritoneal cavity, so that the patient was diagnosed as pancreatic ascites due to disruption of the cystic lesion. Pancreatic ascites has become recognized as a complication of chronic pancreatitis and diagnosed as evidence of internal pancreatic fistula. ERP does not always demonstrate internal pancreatic fistula and there are possible complications associated with ERP, which include recurrence of pancreatic ascites. In this case, the patient has no apparent history of chronic pancreatitis and pancreatic ascites did not recur after ERP.View full abstractDownload PDF (3497K) -

JOURNAL FREE ACCESSA76-year-old woman was admitted to our hospital because of liver dysfuntion andcholedocho-pancreatic duct dilatation. Abdominal US showed a choledochal stone and a solidmass, which revealed strong blood signal by means of color Doppler imaging, in the permampullary region. The choledochal stone was extracted endoscopically after sphincterotomy.Biopsy from the surface of the exposed mass was performed and histology revealed neuroendocrine tumor. Pyrolus-preserving pancreaticoduodenectomy was performed. The tumorproduced only pancreatic polypeptide which was confirmed by the imxnunohistochemical technique. The tumor was extended along the main pancreatic duct to the ampulla of Vater, whichmay have caused the formation of choledochal stone. The location of tumor suggested that thetumor arised from endocrine stem cell in the pancreatic duct epithelium. PPoma is extremelyrare, and only five cases have been reported previously in Japan.View full abstractDownload PDF (13576K) -

JOURNAL FREE ACCESSThere are patients in whom aspiration remains a problem after plaeeznent of percutaneousendoscopic gastrectomy(PEG). Placing a jejunal feeding tube through a pre-existing PEG hasbeen performed as an alternative to patients with a history of aspiration pneumonia. However, placement of a jelunal feeding tube by conventional techniques is often difficult, This is adescrzption of the results of a simple device method for placement of thick jejunal tubes bymeans of using an ultrathin endoscope. The tube placement was accomplished in 16 patientswithin 15 minutes. Patient with placement of jejunal feeding tube by this method preventedfever end aspiration of feeding solution.View full abstractDownload PDF (6685K)
