Eight patients over age 60 years had sudden onset of acute abdominal pain and rectal bleeding in the absence of prior inflammatory bowel disease. Several improved on medical therapy alone; those who required surgery suffered no recurrence up to 6 years. Although the pathologic specimens on these patients were first considered to represent ulcerative colitis or Crohn's disease, their histories and clinical courses are much more consistent with ischemic colitis. Since there are only a limited number of reactions that the bowel can muster against a host of damaging processes, histologic criteria alone are usually not sufficient to separate ischemic disease of the colon from ulcerative colitis and Crohn's disease. This is also true of radiographic features. Thus the diagnosis of ischemic colitis rests on clinical onset and course after treatment.

Crohn's disease of the small intestine is usually managed by medical therapy with surgery being reserved for obstruction or fistula formation. A patient is described who developed small bowel obstruction due to an adenocarcinoma of the ileum after over twenty years of medical therapy for Crohn's disease, originally diagnosed at a laparotomy for acute abdominal pain. The possibility of malignancy in such long-standing disease should be considered.

Two hundred and fourteen patients with Crohn's disease (CD) consecutively admitted during a 5-year period were observed for a mean of 9 years (range, 0-35 years). Sixty-five per cent had their initial symptoms between 10 and 30 years of age and 9.2% after the age of 50 years. The CD diagnosis was delayed for more than 10 years in 8% (mean, 4.5; range, 0-31 years). Large-bowel involvement was seen in 82.5% and was the only localization of the disease in a fourth of the patients. Recurrent abdominal pain occurred in two-thirds of patients with ileal or ileocolic disease. Acute abdominal pain was the cause of laparotomy in 14% of the patients with ileocolic CD. Diarrhea and rectal bleeding occurred significantly more often in colonic CD, whereas fistula complicated ileocolic disease more often than isolated involvement of small or large bowel. Associated extraintestinal diseases were seen in 117 patients (55%), most frequently related to colonic involvement (joint disease, 21%; eye, 12%, skin, 8%). Of 26 patients (12%) with liver pathology, 10 patients had amyloid deposits. Amyloidosis was diagnosed in altogether 12 patients (6%).

The authors review the color Doppler ultrasonographic (US) features of appendicitis and other diseases that can manifest with acute lower abdominal pain. Causes of acute abdominal pain, other than appendicitis, include gynecologic abnormalities (ovarian cyst, ovarian torsion, pelvic inflammatory disease), gastrointestinal abnormalities (infectious enteritis, Crohn disease, mesenteric lymphadenitis, intussusception), and urinary tract diseases. On color Doppler images, inflammatory and infectious processes usually show locally increased blood flow, whereas cysts and twisted masses have absent blood flow. Enlarged lymph nodes also are avascular. Color Doppler US is a useful adjunct to gray-scale US in evaluating acute lower abdominal pain in children and can aid in defining and clarifying gray-scale abnormalities.

99 patients, 67 of whom were female, with a mean age of 25.5 years, were admitted as emergencies between 1991 and 1992 for acute abdominal pain of unknown aetiology. The follow-up, carried out prospectively, was 100% at 1 month, 98% at 6 months, 95% at 1 year, 84% at 2 years. The patients were divided into 3 groups: group I: 42 patients only underwent investigations; group II: 31 underwent laparoscopy, and the appendix was left in place after being considered to be normal by the surgeon; group III: 26 underwent laparoscopic appendicectomy for a histologically normal appendix. For 90% of patients, the painful episode never returned. In the other cases the pain returned within one year, but there was no difference between the three groups (11.2%, 9.6%, 11.5%) (ns). The causes found at the second admission were largely genital, or rare diseases (Crohn, Spiegel hernia). 2 patients were operated for acute appendicitis, not recognized in Group I. In those who had a laparoscopy (Group II and III), the incidence of persistent pain was identical whether the appendix was considered to be normal by the operating surgeon or found to be normal histopathologically. This study suggests that: after admission for acute abdominal pain of unknown cause, the incidence of recurrence of pains is of the order of 10% within one year; the investigations carried out during the patient's admission, allowed the exclusion of serious diseases for three years; the risk of missing a true appendicitis is small (2.5%) and has no prognostic significance; the finding of a normal appendix during laparoscopy should not necessarily lead to its removal; one year follow-up is sufficient to assess the outcome of abdominal pain of unknown cause.

Patients with acute abdominal pain are a great challenge to the radiologist. The clinical diagnosis is classically unreliable, resulting in both negative laparotomies as well as ill-advised surgical delay in a large number of patients. Ultrasound offers a non-invasive way to decrease both false-negative and false-positive diagnoses in this category of patients. This article focuses on the role of sonography in the diagnosis of acute conditions of the gastrointestinal tract tract such as appendicitis, sigmoid diverticulitis, Crohn's disease, colitis, infectious ileocecitis caused by Yersinia, Campylobacter or Salmonella, right-sided colonic diverticulitis, bowel malignancy presenting acutely, small bowel obstruction, intussusception, omental infarction, and epiploic appendagitis. The sonographic spectrum of these conditions as well as possible pitfalls are discussed using illustrative case histories.

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 purpose of our study is to emphasize the central role of ultrasound (US) in finding the cause of abdominal pain in children. Ultrasound of the lower abdomen quadrant should be considered in all cases in which the clinical signs and symptoms are not diagnostic of appendicitis. There is a wide range of clinical syndromes and diseases which can easily be diagnosed using a high resolution ultrasound with adjunct of color and power Doppler. The spectrum of abnormalities includes appendicitis, mesenteric lymphadenitis, infectious ileocecitis, Crohn's disease, intussusception, ovarian cysts, and encysted cerebrospinal fluid. One of the most common causes of acute abdominal pain in children is acute terminal ileitis (infectious ileocecitis) with mesenteric lymphadenitis. Ultrasound is the best tool to rapidly differentiate this disease from acute appendicitis, and prevent unnecessary laparotomy (Ref. 12).

A rare case of multiple small bowel ruptures due to ischemic enteritis (ISE) is reported. The patient was admitted to the hospital with acute abdominal pain followed by bloody diarrhoeas. Preoperative colonoscopic findings were similar to those presented in Crohn's disease. Intraoperatively, ischemic lesions and multiple ruptures were localized at the jejunum and the proximal ileum. Histopathological examination of the resected bowel segment established the diagnosis of ISE. Although ISE is not common, concurred multiple ruptures of the small bowel is a rare but actual complication.

A 48-year-old patient known to have Crohn's disease (diagnosis verified by clinical findings, histology and colonoscopy) was admitted to the hospital with acute abdominal pain. Additional examination did not suggest another pathology. Acute mesenteric ischaemia was suspected late and diagnosed only during laparotomy. CT scan and MR were normal, but abdominal angiography confirmed total occlusion of the superior mesenteric artery. In this case the outcome was death.
