Disorders of urachal remnants are common. While urachal cysts are usually asymptomatic, infection may mimic a variety of acute abdomen. Here we report a very rare case of urachal cyst that protruded in the urinary bladder cavity and among 99 accumulated cases, only 4 cases have been reported similar to this case characterized by intravesical development from 1990 to 1999. An uninfected urachal cyst was found in a 79-year-old male who had died of bile duct carcinoma. The cyst showed ovoid protrusion into urinary bladder cavity from the dome (3.5 x 2.0 x 2.0 cm in size). Histopathologically, the cyst wall was thin and consisted of fibrous connective tissue with muscular tissue and peripheral nerve, and lined by cuboidal epithelium but no inflammatory cells could be seen. Urachal cysts occur in both sexes are affected with equal frequency, and frequently occur in a younger population. In clinical symptoms the umbilical manifestations are predominant in patients younger than 30 years old, while the bladder manifestations are predominant in those older than 30.

A case of mesenteric vein gas as a nonfatal complication of intestinal obstruction is reported. A 48-year-old woman presented postoperatively signs and symptoms of acute abdomen on the eighth day following a gastric pull-up surgery due to an oesophageal carcinoma. The abdominal tomography findings revealed dilated jejunal segments and free gas in the superior mesenteric vein and end branches of the portal vein in the left hepatic lobe. The patient underwent a second laparotomy with a provisional diagnosis of intestinal ischaemia. Intraoperative gross appearance of the intestines revealed no ischaemic finding, the pathology was the dense adhesions between the jejunal segments and previous incision site. On the basis of these findings, the operation was ended with adhesiolysis. One month after the operation, the patient was well, there were no complications. As the authors, we think that the main reason for portomesenteric gas is mucosal destruction and that these case may be followed conservatively as long as intestinal ischaemia is excluded.

Two female patients, aged 50 and 62 years respectively, who were treated with irinotecan, fluorouracil and folinic acid (Saltz scheme) due to metastasised colorectal carcinoma, developed progressive abdominal pain, fever and leucopenia. One patient also exhibited intestinal obstruction. The main problem was differentiating between an acute abdomen and irinotecan toxicity. Both patients recovered without the need for an operative intervention. One patient was treated by means of colonic stent placement. The combination of gastrointestinal irinotecan toxicity and pre-existing passage problems is dangerous. However, in such cases restraint should be exercised with respect to operative interventions.

Xanthogranulomatous cholecystitis is a rare variant of chronic cholecystitis characterized by severe proliferative fibrosis and accumulation of lipid-laden macrophages in areas of destructive inflammation. The macroscopic appearance generally mimics a gallbladder carcinoma. Twelve cases of xanthogranulomatous cholecystitis were identified from a retrospective analysis of the patient records of 770 cholecystectomy cases operated on in our department from January 1996 to October 2001. There were four men and eight women. Mean age of presentation was 52.5 years. Eleven patients had gallbladder stones. Seven patients had a history of acute cholecystitis and five patients of biliary colicky pain. Five cases were presented with obstructive jaundice and five with acute cholecystitis. Right upper quadrant mass was palpable in three patients. All patients underwent cholecystectomy. Open surgery was planned and performed in three patients. Laparoscopic cholecystectomy was planned in nine patients but converted to open surgery in three cases. Nine patients had an uneventful postoperative course. One patient developed wound infection and one patient a postoperative pulmonary infection. One patient developed acute abdomen in the 2nd postoperative day and was re-operated for bile peritonitis. No mortality was seen in the series.

Although multislice, helical CT is increasingly replacing ultrasonography for the evaluation of patients with acute abdominal pain, ultrasound does have certain specific advantages over CT. This article discusses the advantages of ultrasound in imaging of the acute abdomen, exploring such areas as appendicitis, ileocecal Crohn's disease, infectious ileocolitis and infectious ileocecitis, mesenteric lymphadenitis, cecal carcinoma, sigmoid diverticulitis, right-sided colonic diverticulitis, and perforated peptic ulcer.

The Authors report a case of acute abdomen caused by a perforated solitary diverticulum of the cecum recently treated. This is a rare disease that usually is diagnosed, in the surgical theatre because it is a topic of emergency surgery. From Literature analysis it is obvious that a correct preoperative diagnosis is difficult to make because of the large number of possible abdominal pathologies with similar symptoms. Also the therapeutic approach is so extremely variable that the operation could range from a simple conservative type to right hemicolectomy. A proper approach will be conservative with a simple diverticulectomy when the inflammatory reaction is localized in the colonic wall while a right colectomy could be performed when the inflammatory reaction is more advanced or a large mass suggestive of a carcinoma is present.

Carcinoma of the colon during infancy and childhood is a rare disease, and the diagnosis is usually not taken into consideration in a child complaining of abdominal pain. Owing to the lack of awareness of its occurrence and the histological cell type, it generally presents as advanced disease. We report on the case of a 14-year-old patient admitted to hospital with an acute abdomen and a 2-month history of night sweats and weight loss of 10 kg. Ultrasound and computed tomography revealed an unclear mass of the lower abdomen, and colonoscopic histopathologic examination disclosed an obstructing tubular-papillary adenocarcinoma of the sigmoid colon. Colonic carcinoma should be included as a differential diagnosis in young patients with abdominal pain of unknown etiology.

This is a detailed histological autopsy study of 47 cases of macroscopically recognisable flat intraendometrial haemorrhage into the atrophic lining of the uterine cavity. The average age of the studied women was 71 years. The majority of the deceased patients (61%) had suffered from various cardiovascular diseases or acute abdomen; the rest had disseminated carcinoma, chronic lung, kidney or liver diseases. The most common cause of death was cardiovascular failure (68%), followed by respiratory failure, cerebrovascular accident and renal or liver failure. We have observed serious vascular changes in other organs in 22 cases (46%), many of these affected the gastrointestinal tract. The histological examination has always showed congestion of the endometrium and myometrium. In 38 cases there was also marked haemorrhage into the endometrial stroma which occasionally extended into the myometrium. The intensity of the bleeding resembled a haemorrhagic infarction in several instances. The myometrial arteries exhibited a variable degree of atherosclerosis with narrowing of their lumen. In our opinion, apoplexia uteri is caused by the state of permanent hypoperfusion leading to passive hyperaemia, and it is related to the degree of the arterial stenosis.

Colorectal carcinoma emergencies during pregnancy are exceptionally rare. Three women 38, 31 and 36 years old, in the third trimester of gestation received treatment, respectively, for acute abdomen due to perforation of rectal carcinoma, ileus due to a sigmoid tumor, and deep venous thrombosis (DVT) from a cecal tumor compromising the right iliac vein. In the first two patients urgent cesarean sections were carried out with Hartmann's procedure and a loop colostomy was performed to resolve the ensuing intraabdominal sepsis and ileus, respectively. In the third patient, a cesarean section was carried out to treat the underlying DVT more aggressively, while right colectomy was postponed for three weeks. Restoration of the alimentary tract was achieved two months later in the first case, while in the second and third cases total colectomy due to familial polyposis and right colectomy were performed three weeks after the cesarean section. An overview of the clinical features, diagnostic pitfalls and therapeutic approaches to manage complications of colorectal cancer during pregnancy are discussed.

Treatment of acute colorectal malignant obstruction, by using self-expandable metallic stents is useful for both palliative and decompressive therapy before the final surgical treatment. In this case, the patient may be benefit from a period of medical optimization prior to undergoing planned surgical resection by a colorectal surgeon. This is a minimally invasive procedure, relatively safe, which obviates the need for colostomy for evacuation relieving physical and psychological burden and contributing the improvement of quality of life. Furthermore, this method also has the advantage of being cost-effective. The previous experience in the benign biliary stenosis allowed the extension of using the metallic stents also for the treatment of benign colorectal diseases (diverticular occlusion, anastomotic strictures, colonic endometriosis). Complications of colon self-expandable metallic stents placement may occur during the procedure and soon after placement (early complications) or, rarely, late after insertion (late complications). These include bleeding, re-obstruction, pain, tenesmus, stent migration, and perforation. The authors report a case of an 81 year-old woman with inoperable rectal carcinoma with liver metastasis who underwent palliative treatment of self-expanding metallic stent endoscopic placement. One month later, the patient presented with acute abdomen at Accidents and Emergencies Department. The diagnosis was a late rectosigmoid junction perforation by stent placement.
