JOURNAL FREE ACCESSThe effects of cleaning and disinf ection on bacteria contaminated endoscopes were investigated both experimentally and clinically by assaying of the remaining bacteria with a stripping solution. In the experimental study, an endoscope was artificially exposed with either Pseudomonas aeruginosa or Mycobacterium terrae, and the external surf ace, the channels, and the valves of the endoscope were cleaned and disinfected. Cleaning alone produced the following reductions in bacterial counts : external surface, 105 before cleaning, l00-101 after cleaning ; suction channel 106-107 before, 103-104 after; air/water channel 105-106 before, 102-103 after ; valves, 105-106 before, 104-105 after. Completely negative results, however, were not obtained. Disinfection performed in addition to cleaning produced a virtually total elimination of residual bacteria. In 14 cases of clinical studies, cleaning performed on each of the endoscope components produced the following effects in terms of bacterial counts : external surface, including valves, 105-107 before, 103-105 after; channels, 106-109 before, 101-103 after. Disinf ection combined with cleaning produced a virtually total elimination of bacteria of endoscopes. Thus, it is concluded that sufficient degree of reduction in bacterial counts can be achieved by performing disinfection in combination with the cleaning of the endoscopes from our experiments and clinical studies.View full abstractDownload PDF (879K) -

JOURNAL FREE ACCESSChronic unexplained diarrhea is a common complication of human immunodeficiency virus (HIV) infection. However, only a few cases have been reported regarding colonoscopic features of HIV associated colitis. We report three cases in which typical colonoscopic features of HIV associated colitis were observed. Histological and seroimmunological studies suggest that cytomegalovirus was the main pathogen in our cases. In clinical manifestation, every case had chronic diarrhea and massive colonic hemorrhage with hypovolemic shock appeared in one case. In that case, endoscopically multiple "punched-out" ulcers were detected in the entire colon. In two other cases, submucosal hemorrhage, aphthoid erosions and "rosette-like " redness were detected. Patients were treated with ganciclovir and this treatment resulted in a good response.View full abstractDownload PDF (5747K) -

JOURNAL FREE ACCESSA 57-year-old man with epigastralgia and bloody diarrhea was admitted to the Tsuchiya General Hospital. After admission, the patient developed acute renal failure associated with rhabdomyolysis according to severe dehydration. The diagnosis of intestinal tuberculosis was confirmed in our hospital by fluorscopic and colonoscopic examination showing deformity of Bauhin's valve and canal-like stenosis with ulcer in the terminal ileum. We treated the patient by anti-tuberculous drugs (RFP and INH). However, his symptoms and laboratory data did not improve. On the following days, the patient developed intestinal ileus and ileocecal resection was performed. Histologic examination of the resected specimen revealed ischemic enteritis. Mycobacterrium tuberculosis was detected in the biopsy specimen by polymerase chain reaction (PCR) method. Based on these results, this patient was diagnosed as ischemic enteritis associated with intestinal tuberculosis.View full abstractDownload PDF (7979K) -

JOURNAL FREE ACCESSA 72-year-old woman with lower abdominal pain was admitted to our hospital. The final diagnosis was the retrograde intussusception caused by a tubulo-villous adenoma of the sigmoid colon. Barium enema showed poor distensiblity and shortening of the sigmoid colon and tapering of the descending colon. Endoscopic examination revealed narrowing of the descending colon with discolored mucosa and a protruding tumor at the oral site of the stenotic lumen. These findings are characteristic of the clinical diagnosis of retrograde intussusception.View full abstractDownload PDF (5763K) -

JOURNAL FREE ACCESSA 51-year-old man was referred to our hospital because of a positive fecal occult blood test. Colonoscopy revealed an unusual pedunculated polypoid lesion on the terminal ileum. The surface of the polyp was rough and granular, with hump-like protrusions, and it looked like "a gingerroot". The polyp was negative for cushion sign and biopsy specimens showed no neoplastic cells. Computed tomography demonstrated that the polyp was a lipoma with ileocolic intussusception. A laparoscopic ileocecal resection was performed. Histopathological findings of the resected specimen showed a lipoma derived from the muscle layer of the terminal ileum. This type of lipoma is extremely rare and its origin apparently contributed to the interesting endoscopic findings in this case.View full abstractDownload PDF (6950K) -

JOURNAL FREE ACCESSThe patient was a 48-year-old woman who presented with rectal bleeding. Colonoscopy revealed a lesion in the terminal ileum suggestive of submucosal tumor. A histological diagnosis of malignant lymphoma was made based on a biopsy taken from the center of an eroded lesion. In the majority of cases, malignant lymphoma of the ileum is discovered after the patient has developed acute abdominal symptoms such as intussusception. There have been few reports of a definitive diagnosis being made before surgery, and it is especially rare for the diagnosis to be made in a patient without a palpable tumorr who presents with rectal bleeding, as in our case.View full abstractDownload PDF (5059K) -

JOURNAL FREE ACCESSThe use of self-expanding metallic stent (EMS) in rectal strictures has been rarely reported. We experienced a case of malignant rectal stricture treated with EMS. A 84-year-old woman visited our department for evaluation of constipation. Histologic examination of rectal biopsy specimens showed well differentiated adenocartinoma. CT scan revealed markedly thickened rectal wall with pelvic involvement. After insertion of EMS (Ultraf lex, 18-21mm in diameter and 10cm in lengh) into the stenotic lesion, the patient was able to maintain bowel activity and avoid colostomy. It is suggested that EMS will be effective in patients with inoperable rectal stenosis.View full abstractDownload PDF (3491K) -

JOURNAL FREE ACCESSCase 1: A 76-year-old woman was admitted to our hospital for the purpose of further examination of positive immunological occult blood. Double contrast study and colonoscopy showed a pedunculated polyp with a long stalk, measuring 5 cm in length, in the rectosigmoid colon. Case 2 : A 69-year-old man was admitted for paralytic ileus. Colonoscopy showed a pedunculated polyp with erythematous surface, measuring 3 cm in length, in the descending colon. In two cases, a polypectomy was performed. Histological examination of two cases showed the polyps composed of normal mucosa and edematous submucosal layer with lymphangiectasia, suggesting colonic muco-submucosal elongated polyp (CMSEP) of which Matake et al proposed. We reviewed 11 cases of CMSEP on the Japanese literature.View full abstractDownload PDF (6202K) -

JOURNAL FREE ACCESSA 71-year old man was admitted to our hospital with a chief complaint of constipation. The patient was diagnosed as having a villous rectal tumor 8.5 cm in maximal diameter by proctoscopy and barium enema examination. Endoscopic treatment was selected because he had been taking long-term oral steroids for rheumatoid arthritis and had a history of diabetes mellitus. A total of 17 endoscopic treatment, i. e., removal of the tumor and mucosal cautery under endoscopic control, were conducted over a 22month period. These treatments revealed a pathologically definitive diagnosis of adenocarcinoma in villous adenoma. During the 3 years from the final treatment, the patient had no evidence of recurrence. In the absence of invasive cancer, endoscopic treatment will become the therapeutic option of choice for the treatment of villous tumor of the rectum, irrespective of tumor size.View full abstractDownload PDF (6179K) -

JOURNAL FREE ACCESSA 84-year-old woman was referred to our hospital because of liver dysfunction. Ultrasonography, computed tomography and magnetic resonance imaging did not reveal the tumor in the pancreas. Only endoscopic retrograde cholangiopancreatography (ERCP) and magnetic resonance cholangiopancreatography showed a small protrusion in the main pancreatic duct. The biopsy of the tumor under ERCP revealed intraductal papillary adenoma of the pancreas and duodenum-preserving pancreatic head resection was performed the resected tumor, 0.8 x 0.7 cm in size, was diagnosed as intraductal papillary adenoma of the pancreas by pathological examination. A rare case of minute intraductal papillary adenoma of the pancreas is reported and the usefulness of ERCP and biopsy under ERCP was discussed.View full abstractDownload PDF (3196K) -
