The diagnosis of enteric intussusception is rare in adults but not in children. The clinical picture often takes an insidious course. Acute abdomen may also be caused by enteric intussusception. We report on three patients with enteric intussusception and acute abdomen. In two cases, a CT led to the diagnosis of invagination of the small intestine. In one patient, invagination of the terminal ileum was detected during coloscopy. All patients were submitted to limited segment resection and end-to-end anastomosis. In all three cases, the invagination was caused by benign pathological changes. Enteric intussusception in adults always requires surgery. In more than 95% of the cases, pathological findings are obtained intraoperatively, which are benign in the small intestine in 85-95% of the cases.

Intussusception, although a common cause of pediatric surgical emergencies, is a rarely fatal condition. A 7-month-old infant who was discovered in her cot was unresponsive and pronounced dead after 2 h of uneventful cardiopulmonary resuscitation in an emergency hospital. Forensic autopsy which was performed in order to clarify the circumstances surrounding the death revealed intussusceptions at two sites of the ileum. Although morbidity and mortality rates from the condition have progressively declined in recent decades but avoidable deaths still occur as was experienced in the present case. The forensic pathology significance in this case was the occurrence of 'painless intussusception' whereby the affected child clinically exhibited no discomfort or characteristic features of acute abdomen until death. In summary, the present case has exhibited an uncommon fatal occurrence and demonstrated the importance of forensic autopsy in such unexpected sudden infant deaths.

We describe a 53-year-old man with a history of diarrhea temporally related to the use of flutamide. He developed an acute abdomen, and presented with an ileocecal intussusception due to an edematous ischemic cecum. The ischemia was due to enterocolic lymphocytic phlebitis (ELP), with numerous associated thrombi. The phlebitis involved not only the ischemic area but also the grossly unaffected areas, including the entire right colon, terminal ileum, and appendix. All layers of the bowel wall were involved. Mesenteric veins were also prominently affected, but the arteries were spared. This rare form of vasculitis was associated with a marked lymphocytic infiltrate involving the epithelium of the entire right colon, ileum, and appendix. This is the first reported case of ELP occurring in conjunction with lymphocytic colitis, lymphocytic enteritis, and lymphocytic appendicitis. The temporal association of the patient's symptoms with flutamide use suggests that this peculiar form of lymphocytic inflammation of the veins and mucosa likely represents a drug reaction. We suggest that some cases of lymphocytic colitis may also be associated with ELP but are unlikely to be recognized unless affected submucosal vessels happen to be included in the biopsy.

Intussusception is one of the most common causes of acute abdomen in the first year of life. Its clinical presentation is vomiting, bloody stools, severe colicky abdominal pain, and mass. The authors reported a case of intussusception with an inappropriate clinical picture, but both characteristic ultrasonography and computed tomography findings led to the diagnosis of ileo-ileal intussusception.

Intussusception is defined as the telescoping of one segment of the gastrointestinal tract into an adjacent one. It is relatively common in children and is the second most common cause of an acute abdomen in this age group. It is much less common in adults and accounts for less than 5% of cases of mechanical small bowel obstruction. Whereas the diagnosis is usually already suspected in children before imaging, it is often made unexpectedly in adults. In addition, although in children there is usually no specific underlying cause, an underlying lead point is often present in adults. Plain film radiography, barium studies and ultrasound imaging play major roles in both the diagnosis and management of this condition, and it is increasingly common for the diagnosis to be made by CT and MRI, particularly in adults. This pictorial essay reviews the imaging features that may be found in patients with bowel intussusception. As well as describing the imaging features of the more commonly used tests, we also stress the role of emerging technologies such as MRI using ultrafast half-fourier sequences with single shot turbo spin echo.

The aim of the study was analysing of the diagnostic value of different imaging modalities in evaluation patients with bowel obstruction. The material comprises a group of 47 patients with diagnosed acute abdomen. Erect radiography, and radiographs in supine and left lateral patients' positions, US and CT examination were performed in those patients. CT examination was performed in 5 mm--and 10-mm thick axial sections before and after administering the contrast agent. In 6 patients small barium enema was performed. In 5 cases water-soluble contrast was administered orally. In 6 cases on plane radiographs the presence of high small bowel obstruction was found. In 3 cases the level of small bowel obstruction was in the distal ileum. In 12 patients the obstruction of large bowel was seen on plain radiographs. In 3 patients intussusception of sigmoid bowel was found. The mesenteric ischemia was found to be a reason of bowel obstruction in 5 cases. On CT section soft tissue mass with irregular contrast enhancement was found, reflecting ischemic intestinal loops. In 2 patients the gall stone small bowel obstruction was found. In one of them the presence of gas in the biliary tree was seen on CT images. The determining of the level of the obstruction is facilitated on plain radiographs, erect and in supine and left lateral patients' position. In small bowel obstruction, normal or equivocal initial radiographs may result in a delayed diagnosis. As the bowel diameter cannot be assessed the plain radiographic diagnosis is difficult or impossible. If there is persistent diagnostic difficulty, follow-up plain radiographs taken a few hours later will often resolve the problem and, if not, a barium study or CT may be performed. Orally administering of water-soluble contrast agent, diluted barium, barium enema are also helpful in differentiating the character and etiology of obstruction.

Infestation with Ascaris lumbricoides (roundworm) is very common in the tropics and subtropics. Patients with ascariasis can be asymptomatic or may present with different clinical features in the form of simple nausea, decreased appetite, abdominal pain or more severe bowel obstruction, perforation, intussusception, biliary colic etc. Ultrasonography (USG) can be quick, safe, noninvasive and relatively inexpensive tool in diagnosing the presence of worms and also evaluating response to treatment (1, 2, and 3). Here we present four cases of roundworm infestation presenting with acute abdomen in the emergency department, which were diagnosed by USG and further imaging features of ascariasis on USG is described.

Throughout the 1960s and 1970s, pigbel (enteritis necroticans) was the most common cause of death in children over the age of 1 year in hospitals in the highlands of Papua New Guinea (PNG). There has been recent widespread perception that after the successful vaccination program in the 1980s the disease virtually disappeared. A new vaccine is now available, but disease burden information is conflicting: despite almost no pigbel being reported from major hospitals there have been many reports of the disease from outlying health centres. This study aimed to provide information on the disease burden of pigbel in PNG, so that appropriate vaccine policy decisions could be made. We conducted a 12-month prospective study of all cases of acute abdomen in children presenting to 38 health facilities, 29 health centres and 9 hospitals in the highlands. Children were eligible for inclusion if they were aged 1-12 years and had abdominal pain of less than 2 weeks' duration. A standardized case definition of pigbel was used to distinguish cases of acute abdominal pain very likely to be due to pigbel from cases very likely to be accounted for by other diagnoses (such as gastroenteritis, typhoid, dysentery, intussusception, urinary tract infection and others). A total of 119 cases of acute abdomen were reported from 17 of the 38 health facilities involved. Of these 119 cases 11 met the criteria for pigbel and a further 8 were probable cases. There were 4 deaths among the 119 children with acute abdomen: 2 from definite pigbel, 1 from probable pigbel and the other due to complications of measles. In 2002 pigbel was the cause of between 9% and 16% of presentations with acute abdominal pain in children in the PNG highlands. The overall disease burden of pigbel was relatively small (19 definite or probable cases and 3 deaths in 12 months). However, there was substantial geographical clustering of cases: more than 50% of the definite cases occurred in children living within three electorates on the Western Highlands-Enga provincial border, no more than 40 km from each other. This study will be useful in planning pigbel vaccine policy and future surveillance.

Jejunogastric intussusception is a rare complication of gastric surgery. It usually presents with abdominal pain, nausea, vomiting, and hematemesis. A history of gastric surgery can help in making an accurate diagnosis. An early diagnosis and urgent surgical intervention is mandatory. We herein report two cases of patients with jejunogastric intussusception who presented with acute abdomen and hematemesis.

Although intussusception is a well-known cause of acute abdomen in the pediatric population, traumatic intussusception is exceedingly rare and has been reported previously only 6 times in a preadolescent child. We present a case of ileoileal intussusception in a previously healthy 6-year-old boy after blunt trauma to the abdomen and review the English language literature on the subject.
