1/24. 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) |
2/24. 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) |
3/24. 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) |
4/24. 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) |
5/24. Giant fecaloma with idiopathic sigmoid megacolon: report of a case and review of the literature.PURPOSE: fecal impaction is a common condition, and " fecaloma" is an extreme variety of impaction. This is a report of a giant, solitary, and stubborn fecaloma not responding to nonoperative management. A surgical intervention for uncomplicated fecal impaction is rarely needed and reported in the literature. METHOD: A 39-year-old male patient with constipation presented with a firm, mobile, abdominal mass of six-months duration. Investigations revealed an isolated, giant fecaloma in a redundant sigmoid megacolon. After all the conservative measures were unsuccessful in evacuating the stubborn impaction, he was treated by sigmoid colectomy and primary anastomosis. CONCLUSION: A timely surgical intervention in recalcitrant fecal impactions may prevent possible stercoral ulcer perforation with a high mortality.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
6/24. Giant sigmoid diverticulum causing colonic and urinary obstruction.Diverticulosis of the colon is a fairly common disease, but a solitary giant diverticulum is relatively rare.

7/24. 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) |
8/24. Giant diverticulum of the sigmoid colon.The giant colonic diverticulum is a very rare clinical entity usually located in the sigmoid colon of elderly patients. A case of an 87-year-old woman recently treated in our hospital is reported hereinafter. The patient was non-surgically treated due to her advanced age and high surgical risk.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
9/24. Giant lipoma causing a colo-colonic intussusception.intussusception is much more common in children than in adults. Unlike in children, intussusception in adults is associated with an identifiable etiology in 90 per cent of cases. Lipomas are the second most common benign tumors of the colon. Small lipomas are usually asymptomatic and are found incidentally during colonoscopy. Giant lipomas are uncommon causes for colonic intussusception. This usually presents as abdominal pain and vomiting and less commonly as diarrhea. Computed tomography is an excellent method to diagnose giant colonic lipomas, by showing a well demarcated, round, low-attenuated lesion in the lumen of the colon. The definitive treatment for symptomatic lipomas is surgical resection. Both laparoscopic and open resections have been described. Endoscopic resection of colonic lipomas is associated with a high complication rate. In this report, we present a patient with a giant colonic lipoma causing colocolonic intussusception.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
10/24. Case report: uncommon radiological and pathological features of giant colonic diverticula.A case of multiple giant sigmoid diverticula is described in which a barium enema revealed two giant diverticula communicating with the sigmoid lumen. Both diverticula were located on the mesenteric border of the sigmoid colon, and histologic examination showed mucosal and serosal layers with no evidence of smooth muscle. The pathogenesis, pathology, radiological manifestations and differential diagnosis of this rare condition are discussed.- - - - - - - - - - ranking = 6keywords = giant (Clic here for more details about this article) |
