1/71. Sonographic findings in abdominal hereditary angioedema.patients with hereditary angioedema (HAE) may suffer from abdominal pain severe enough to prompt unnecessary surgical intervention. The diagnostic approach to abdominal pain during HAE attacks is not established. We describe abdominal sonographic findings during severe colic in 2 patients with known HAE. Sonography demonstrated marked mucosal thickening and edema of the bowel wall with a variable amount of free peritoneal fluid. These findings are not specific but are consistent with the hypothesized mechanism of attack and resolve after therapy. Abdominal sonography is useful for evaluating acute abdominal pain in patients with known HAE to prevent unnecessary surgery. Conversely, if the described sonographic findings appear in a case of abdominal colic of unknown origin, HAE should be included in the differential diagnosis.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
2/71. angiolipoma of the colon with right lower quadrant abdominal pain.BACKGROUND/AIM: An angiolipoma is a common benign neoplasm with a characteristic vascular component that occurs in the subcutaneous tissue and rarely in the gastrointestinal tract. We report on a 69-year-old man with a submucosal angiolipoma in the cecum. methods: This patient was treated with a laparoscopy-assisted ileocecostomy, and a side-to-side anastomosis was performed extracorporeally. RESULTS: A light microscopic study supported the diagnosis of an angiolipoma of the colon. After 5 years of follow-up, the patient has no symptoms or signs of recurrence. CONCLUSION: The colonic angiolipoma was successfully removed using a minimally invasive laparoscopic technique. copyright copyright 1999 S.

3/71. peutz-jeghers syndrome: case report.A case of peutz-jeghers syndrome (PJS) in an African girl is presented to document the clinical presentation, management and follow up of this condition. The patient who presented with black buccal mucosal hyperpigmentation and clinical features of jejuno-jejunal intussusception was successfully managed by operative reduction of the intussusception and polypectomy. She is being followed up for evidence of malignant transformation in associated intestinal polyps and development of extra-intestinal malignancies at other sites. The management of PJS in light of recent trends is discussed, especially with reference to suggested protocols for screening and surveillance of sites at supposed risk of tumour development.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
4/71. Pseudomembranous enteritis after proctocolectomy: report of a case.Intestinal pseudomembrane formation, sometimes a manifestation of antibiotic-associated diarrheal illnesses, is typically limited to the colon but rarely may affect the small bowel. A 56-year-old female taking antibiotics, who had undergone proctocolectomy for idiopathic inflammatory bowel disease, presented with septic shock and hypotension. A partial small-bowel resection revealed extensive mucosal pseudomembranes, which were cultured positive for clostridium difficile. Intestinal drainage contents from an ileostomy were enzyme immunoassay positive for C. difficile toxin A. Gross and histopathologic features of the small-bowel resection specimen were similar to those characteristic of pseudomembranous colitis. The patient was treated successfully with metronidazole. These findings suggest a reservoir for C. difficile also exists in the small intestine and that conditions for enhanced mucosal susceptibility to C. difficile overgrowth may occur in the small-bowel environment of antibiotic-treated patients after colectomy. Pseudomembranous enteritis should be a consideration in those patients who present with purulent ostomy drainage, abdominal pain, fever, leukocytosis, or symptoms of septic shock.- - - - - - - - - - ranking = 2.024067815852keywords = mucosa, membrane (Clic here for more details about this article) |
5/71. Acute abdomen without cutaneous signs of varicella zoster virus infection as a late complication of allogeneic bone marrow transplantation: importance of empiric therapy with acyclovir.Two patients complained of severe abdominal pain as the first sign of varicella zoster virus infection about 1 year after allogeneic BMT. In case 1, eruptions, found on the face and chest on admission, became vesicular and dispersed on the third hospital day. Though acyclovir (ACV) was immediately started, he died on the fourth day. In case 2, skin rash was never observed during the clinical course. laparotomy on the third hospital day revealed many hemorrhagic spots on the liver surface and mucous membrane of the upper GI tract, indicating disseminated visceral disease. Empiric therapy with ACV was successful.- - - - - - - - - - ranking = 0.012033907926keywords = membrane (Clic here for more details about this article) |
6/71. Toxic pseudomembranous colitis in a patient with ulcerative colitis.Toxic colitis is a severe disease that may be caused by several inflammatory and/or infectious diseases. Ulcerative colitis is one of the most frequent causes of toxic colitis in the united states. Toxic megacolon complicating clostridium difficile colitis is a rare occurrence with significant morbidity and mortality. CASE REPORT: A 52-year-old male presented with rectal bleeding and tenesmus. He had been treated for amebiasis with metronidazole, and had improved. Two weeks later, symptoms recurred, and he was referred to our hospital. A sigmoidoscopy and biopsies demonstrated mucosal ulcerative colitis. He underwent treatment with systemic prednisone, mesalamine, and hydrocortisone enemas with adequate response. He was asymptomatic for 2 months, but later presented with a tender abdomen and rectal bleeding. Plain abdominal and thorax films showed colonic distention and free intraperitoneal air. Emergency laparotomy was performed, and an inflamed and distended colon, with free inflammatory liquid in the peritoneum, was found. A total abdominal colectomy with temporary ileostomy and Hartmann's pouch was performed. The histopathology analysis demonstrated a clostridium difficile pseudomembranous colitis. CONCLUSION: The presence of toxic megacolon due to clostridium difficile in patients with ulcerative colitis is a rare complication that may be suspected in patients with initial relapse who are on antibiotics.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
7/71. Multifocal epithelioid angiosarcoma of the small intestine.A 67-year-old man presented with weight loss, intermittent severe abdominal pain and melaena. Initial radiology (including abdominal ultrasonography), gastroscopy and colonoscopy did not demonstrate any lesions that could explain the complaints. Three weeks later, upper gastrointestinal and small-bowel barium studies revealed two areas in the small intestine with an abnormal mucosal pattern. Explorative laparotomy revealed three tumoral lesions. Three partial enterectomies were performed. Gross examination showed centrally depressed dark reddish tumoral lesions extending from the mucosa throughout the full thickness of the bowel wall (diameter varying between 1.6 cm and 2.2 cm). The tumours, composed of large, plump, polygonal cells showing little architectural differentiation, were mainly situated in submucosa and muscularis propria. The growth pattern appeared rather solid. The epithelioid cells showed pronounced nuclear pleomorphism and atypia with central large nucleoli. There were several small blood vessels with occasional anaplastic endothelial cells. Immunohistochemical staining demonstrated an intense expression of CD 31, CD 34, factor viii related antigen and keratin. This supported the diagnosis of an epithelioid angiosarcoma. The patient died 3 months after diagnosis. Tumours of the small intestine are very rare, and angiosarcomas of the small intestine are even more rare. Epithelioid variants have only been described in two patients and only one of these had a multifocal presentation. The prognosis is very poor. Because of the epithelioid growth pattern and the cytokeratin expression, these tumours may erroneously be diagnosed as a carcinoma.- - - - - - - - - - ranking = 9.3908259585751keywords = muscularis, mucosa (Clic here for more details about this article) |
8/71. Clinical onset of the Crohn's disease after eradication therapy of helicobacter pylori infection. Does helicobacter pylori infection interact with natural history of inflammatory bowel diseases?BACKGROUND: There are conflicting reports concerning the prevalence of helicobacter pylori infection in patients with inflammatory bowel diseases: some studies connected Sulphasalazine therapy and lower incidence of helicobacter pylori infection, but others showed lower prevalence of helicobacter pylori infection in inflammatory bowel diseases despite the choice of therapy. CASE REPORT: A 28-year-old male patient presented in January 1996 with the symptoms of ulcer like dyspepsia. There was no significant abnormality on physical examination, laboratory testing and abdominal ultrasound. histology examination of the biopsy specimen taken during the upper endoscopy revealed helicobacter pylori associated active gastritis only in the corporal part of the stomach. After two weeks eradication therapy (omeprazole, amoxicillin) he was well. Three months later, at the control endoscopy, granulomatous gastritis of the corporal localization was detected, without helicobacter pylori present. Antral mucosa appeared normal, both, on endoscopy and histology examination. In July 1996 he started with cramping abdominal pain, mild periodical fever and episodes of watery diarrhea. In laboratory results we found nonspecific signs of inflammation. We repeated upper endoscopy, colonoscopy and enteroclysis--with evidence of segmental stenotic lesions of the upper part of ileum and jejunum. Again, we confirmed granulomatous gastritis and small granuloma in the proximal jejunum. After starting the 5-ASA therapy in combination with Metronidazol, patient was better clinical condition, and laboratory results were normal. We suggested mesalamine maintenance therapy 1 gr. every day, and three years later he is well, in clinical remission of Crohn's disease. CONCLUSION: The clinical course of the Crohn's disease maybe "sui generis" connected with helicobacter pylori infection- but the exact mechanisms remain to be discovered.- - - - - - - - - - ranking = 1keywords = mucosa (Clic here for more details about this article) |
9/71. Ectopic gastric mucosa presenting as a polypoid mass within a Meckel's diverticulum.A 32-year-old man presented with severe abdominal pain located in the mesogastrium and right hemi-abdomen. A barium transit study showed a tubular structure of 6 cm arising from a bowel loop in the distal ileum, with an intraluminal polypoid mass near the bottom. diagnosis of a benign lesion within a Meckel's diverticulum was made. Anatomopathology confirmed a Meckel's diverticulum and demonstrated that the polypoid mass was caused by an unusual great ectopic island of gastric mucosa.- - - - - - - - - - ranking = 5keywords = mucosa (Clic here for more details about this article) |
10/71. Mesenteric panniculitis of the colon with obstruction of the inferior mesenteric vein: report of a case.Mesenteric panniculitis is a rare disease characterized by nonspecific inflammation of the fat tissue of the mesentery. We present an extremely rare case of mesenteric panniculitis of the sigmoid colon, complicated by occlusion of the inferior mesenteric vein. A 75-year-old male presented with a one-month history of abdominal distention and abdominal mass without pain. physical examination revealed a firm mass in the lower abdomen. barium enema study demonstrated rugged mucosa and a serrated contour in the rectosigmoid colon. Computed tomography showed that the mass arose from the mesentery, which surrounded the mesenteric vessels. The density of the mass was slightly higher than that of fatty tissue. Based on these radiologic findings, the patient was diagnosed as having mesenteric panniculitis of the rectosigmoid colon. colonoscopy showed narrowing with edematous mucosa in the rectosigmoid colon, whereas marked dilated vessels were noted in the proximal portion of the sigmoid colon. angiography showed occlusion of the inferior mesenteric vein, with venous flow returning via a collateral vein. The patient was observed without medication because his condition was satisfactory. His symptoms subsequently disappeared during a period of several weeks. The mass in the lower abdomen gradually diminished in size, disappearing three months later. Computed tomography and barium enema showed improvement of the lesion. The favorable outcome of the present case was probably because of formation of a collateral vein. The present case suggests that aggressive therapy for mesenteric panniculitis should be avoided, because the outcome of this disorder is good, even when there is obstruction of vessels.- - - - - - - - - - ranking = 2keywords = mucosa (Clic here for more details about this article) |
