1/15. Acute lower gastrointestinal bleeding from a dieulafoy lesion proximal to the anorectal junction post-orthotopic liver transplant.A 67-year-old woman underwent an orthotopic liver transplantation for end stage liver disease secondary to chronic autoimmune hepatitis. She developed sudden massive hematochezia on post-operative day 23 with hemodynamic compromise. The source of hemorrhage was found at colonoscopy after careful irrigation and inspection to be a dieulafoy lesion situated just proximal to the anorectal junction. hemostasis was achieved with epinephrine injection and thermal coagulation.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
2/15. actinomycosis of the ano-rectum: a rare infectious disease mimicking carcinomatosis.Abdominal actinomycosis is an infectious disease caused by actinomyces israeli, a usual germ of the gastro intestinal tract. It gives unusual tumoral lesions with abcesses and fistulas. More rarely is abdominal actinomycosis at the end of the abdominal tube. Cope in 1949 said: "actinomycosis occurs so seldom in the colon and the rectum that no surgeon, even if he be a proctologist is likely in a life time to see more than a few cases" (4). An anorectal actinomycosis case that looked like rectal cancer is reported. It was treated successfully by surgery and antibiotherapy. Some anatomopathologic and mainly histologic characteristics lead to the diagnosis. General and pathological aspects, symptoms, diagnosis, differential diagnosis and therapy of anorectal actinomycosis are discussed.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
3/15. Anal ulcerations due to cytomegalovirus in patients with AIDS. Report of six cases.Lesions due to cytomegalovirus (CMV) are frequent in the immunocompromised patient. This is particularly the case in patients with AIDS, where the colon and rectum are the regions most often involved. The authors report six cases of anal ulcerations due to CMV in patients with AIDS. These lesions, confirmed histologically, were either isolated or associated with other localizations. Treatment is based on specific antiviral agents but resistance and recurrence can occur. The current report underlines the importance of histologic examination of anal lesions in hiv-infected subjects.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
4/15. Hiatal herniation of the colon with digestive tract bleeding--a case report.A 71 year old woman with hiatal herniation was admitted to our hospital with anemia and melena. A barium enema revealed hiatal herniation of the transverse colon in conjunction with the stomach, which seemed to be strangulated by the esophageal hiatus. She underwent surgery, for which Hill's gastropexy method was employed and has had no signs of bleeding since. By presenting this case, we stress the importance of marking a careful differential diagnosis due to the variability in symptoms of digestive tract bleeding.- - - - - - - - - - ranking = 5keywords = colon (Clic here for more details about this article) |
5/15. Colo-recto-anal intussusception. Case report.Two cases of colo-recto-anal intussusception are reported, both in old women and with a tumour at the apex of the intussusception. Primary resection of the sigmoid colon with terminal sigmoidostomy was successful in one case. Resection with anastomosis in the other case was followed by anastomotic leakage with peritonitis, requiring revisional closure of the rectum and terminal sigmoidostomy.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
6/15. Balloon dilatation of post-surgical ano-rectal strictures in two infants.Balloon dilatation of ano-rectal strictures offers an alternative to surgical repair of such lesions. This procedure has been described in higher colonic strictures secondary to necrotizing enterocolitis in infants but not in post-surgical ano-rectal strictures. Two cases of successful balloon dilatation are reported. Anal sphincter injury resulting in fecal incontinence, as previously reported [1], did not occur.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
7/15. Anal stenosis and megarectum in the elderly.Anal stenosis, an often unrecognized condition causing acute colonic obstruction in the elderly, is described with reference to three cases. Initial management should include: 1) digital dilatation and rectal examination; 2) sigmoidoscopy; 3) insertion of a rectal tube; 4) correction of fluid and electrolyte imbalance. Sufficient experience is not available to predict the results of sphincterotomy or anoplasty, both of which may result in incontinence, and conservative measures may suffice in most cases. Prevention of this condition may be achieved by adequate intake of dietary fiber or regular bulk laxatives in these debilitated patients.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
8/15. Anorectal herpes: radiographic findings.radiography revealed aphthous ulcers, plaquelike erosions, and deep collar button ulcerations in a patient with herpes involving the rectum and the sigmoid colon. It is concluded that herpes simplex virus should be added to the list of disease entities that produce aphthous and collar button ulcerations.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
9/15. Anal Crohn's disease with carcinoma in situ.A 36-year-old female with a six-year history of Crohn's disease of the anus and colon was found to have in situ cloacogenic carcinoma of the anus after having undergone total proctocolectomy for massive bleeding. This case further supports the association between Crohn's disease of the gastrointestinal tract and its potential for malignant degeneration.- - - - - - - - - - ranking = 1keywords = colon (Clic here for more details about this article) |
10/15. glycogen storage disease type Ib: infectious complications and measures for prevention.A patient with glycogen storage disease (GSD) type Ib, neutrophenia, chronic inflammatory bowel disease and recurrent abscesses was treated with recombinant human granulocyte-macrophage colony stimulating factor (GM-CSF). GM-CSF (and also granulocyte colony stimulating factor) therapy markedly increased the neutrophil counts and reduced the frequency of infections and inflammation. We conclude that myeloid growth factors are effective for the treatment and prevention of acute infections and chronic inflammatory complications in patients with GSD Ib.- - - - - - - - - - ranking = 2keywords = colon (Clic here for more details about this article) |
