1/37. Giant sigmoid diverticulum: a report of three cases.The imaging appearances of three patients with a giant sigmoid diverticulum are described. The prominent feature was a large gaseous lucency noted in the lower abdomen on plain radiographs. Computed tomography (CT) was undertaken in two cases and in these a large gas filled collection was identified containing a small quantity of fluid. In the third case the collection was aspirated, contrast medium injected and a communication with the large bowel demonstrated. The condition is uncommon and needs to be distinguished from sigmoid and caecal volvulus.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/37. amyloidosis presenting as a perforated giant colonic diverticulum.Colonic amyloidosis is frequent, although rarely radiographically evident. The radiological findings are varied and unspecific. We report a case of perforated giant colonic diverticulum (GCD) diagnosed by helical CT in which amyloid deposition was pathologically demonstrated. The patient was a renal transplant recipient who previously had undergone hemodialysis for 10 years. A possible role of amyloidosis in the pathogenesis of this case is discussed. Giant colonic diverticulum must be included in the spectrum of gastrointestinal manifestations of amyloidosis.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
3/37. Giant colonic diverticulum: report of a case.Giant colonic diverticulum is a rare complication of colonic diverticulosis. It typically occurs as a single diverticulum located on the antimesenteric border of the sigmoid colon. The most widely accepted theory for its development attributes the progressive dilation to a "ball-valve" mechanism, allowing air to enter but not to exit. patients usually present complaining of abdominal pain and/or an abdominal mass, although they may remain asymptomatic. physical examination reveals a tympanic abdominal mass that appears as a round radiolucency on plain radiographs and CT. barium enema demonstrates the relationship of the diverticulum to bowel and may document communication with the colonic lumen. To alleviate symptoms and prevent complications, the recommended treatment is excision of the diverticulum in continuity with the involved colonic segment. We report a case and discuss the presentation, diagnosis, and management of giant colonic diverticulum.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
4/37. Giant colonic diverticulum: a rare manifestation of a common disease.Giant colonic diverticulum is a rare manifestation of a common disease primarily affecting patients over the age of 50 years. We reviewed all 81 cases of giant colonic diverticulum reported in the medical literature and present herein an additional case in a younger patient. Published reports were summarized with regard to current epidemiology, clinical aspects, diagnosis, pathogenesis, treatment, and complications. Giant colonic diverticulum can present as an acute, chronic, or incidental condition, or with complications. There are several suggested theories for the pathogenesis of giant colonic diverticulum, but none is universally satisfactory. A diagnosis can be made with plain films, barium enema, and CT scans. A combination of sigmoid resection and primary anastomosis was successful in 75% of the cases reported after the mid-1970s. More than 90% of giant colonic diverticula are found in the sigmoid colon. Sigmoid resection with primary anastomosis is the preferred treatment, although patients presenting with complications typically should be treated with Hartmann's procedure for free perforation or percutaneous drainage for a localized abscess. Because of the high risk of complications, we recommend segmental resection of the involved colon for those found incidentally.- - - - - - - - - - ranking = 3keywords = giant (Clic here for more details about this article) |
5/37. Obstructing giant colonic diverticulum.We report the second case of an obstructing true colonic diverticulum. Of the 103 cases of giant sigmoid diverticulum found in the literature, 13% have been reported as true giant sigmoid diverticulum, ie, containing all layers of the colonic wall. Our 75-year-old patient had clinical symptoms for only 6 months, and endoscopy revealed an almost totally obstructing mass 20 cm from the anus. Surgical resection of the sigmoid colon with a primary anastomosis resolved all of the patient's obstructive symptoms. A flap-valve mechanism was the cause of this true giant colonic diverticulum. Microscopic examination of the diverticulum wall revealed all normal layers of colon wall.- - - - - - - - - - ranking = 7keywords = giant (Clic here for more details about this article) |
6/37. Uroepithelium in a colonic diverticulum.Giant colonic diverticula are rare entities and often present in adulthood as acute diverticulitis. The authors present a case of giant colonic pseudodiverticulum lined with uroepithelium causing bowel obstruction in a neonate. The presence of uroepithelium in a colonic pseudodiverticuium remains unexplained and to the authors' knowledge unreported. This heterotopic tissue may be a result of an embryonic rest or could be urachal in origin adhering initially to the colon and eventually detaching from the umbilicus. These lesions should be resected because of the risk of infection, perforation, or obstruction.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
7/37. Lipomatous polyposis of the colon with multiple lipomas of peritoneal folds and giant diverticulosis: report of a case.A case of multiple lipomatosis exclusively located in the colon is reported in a young male (33 years). It is characterized by a great number of lipomas with polyposis growth appearance, multiple lipomas of peritoneal folds, and giant diverticulosis probably caused by weakened areas of colonic wall induced by the lipomas.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
8/37. Giant diverticulum of the sigmoid colon with perforation. Report of a case.We present a case of perforated giant diverticulum of the sigmoid colon. This condition is extremely rare and only a few cases have so far been reported in the literature. Our case involved a 55-year old woman. diagnosis was easy with barium enema and CT scan examination. laparotomy revealed a giant diverticulum of the sigmoid colon compressing adjacent structures with signs of inflammation. An en bloc resection of the sigmoid colon, ovary and fallopian tube was performed with primary colon-rectal anastomosis.The post-operative course was uneventful.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |

10/37. Giant diverticulum of the colon: report of two new cases and review of the literature.Diverticulosis coli affects more than one in three individuals older than 65 in the western world. Giant diverticulum of the colon is an extremely rare complication of diverticular disease; only 113 cases, mostly situated in the colon sigmoideum, have been reported in the world literature. Two new cases of giant diverticulum of the colon sigmoideum, with totally different clinical presentation, diagnosis, and management, are reported-one being the cause of chronic anemia and the other presenting as an acute abdomen. Based on a review of the literature, an update on symptomatology, diagnosis, pathogenesis, and therapeutical options of this rare disorder is provided.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
