786 patients with suspected acute appendicitis or appendiceal mass were examined by ultrasonography to distinguish appendicitis from bacterial enteritis. 533 of these patients were described before. In 91 (11.6%) ultrasonography revealed the characteristic picture associated with bacterial enteritis of the ileocaecal region-enlarged mesenteric lymph nodes and mural thickening of the terminal ileum and caecum--but no image of an inflamed appendix. In 64 of these a bacterial infection was confirmed (Yersinia enterocolitica in 28, Campylobacter jejuni in 24, Salmonella enteritidis in 11, Yersinia pseudotuberculosis in one). In the other 27, bacteriological tests were negative (17) or not performed (10). Only 34 of 91 had diarrhoea. Six of the 91 patients underwent surgery, in all of them the removed appendix was normal. The other 85 patients recovered with conservative treatment. In 38 a planned appendicectomy was cancelled because of the sonographic findings. Bacterial enteritis limited to the ileocaecal region (bacterial ileocecitis) appears to be responsible for an appreciable number of unnecessary appendicectomies. It has characteristic sonographic features which distinguish it from appendicitis.

533 consecutive patients with suspected acute appendicitis or appendiceal mass were examined by ultrasonography to distinguish acute appendicitis from bacterial enteritis. In 61 (11.4%) ultrasonography revealed the characteristic picture associated with bacterial enteritis of the ileocaecal region--enlarged mesenteric lymph nodes and mural thickening of the terminal ileum and caecum--but no image of the appendix. In 41 of these a bacterial infection was confirmed: infection due to Yersinia enterocolitica in 21, Campylobacter jejuni in 15, Salmonella B in 3, Salmonella C in 1, and Yersinia pseudotuberculosis in 1. In the other 20 bacteriological tests were negative (10) or not done (10). Oral barium studies, done in 15 patients, showed thickening of the terminal ileum in all of them. Only 22 of the 61 patients had diarrhoea. Yersinia enteritis clinically simulated an appendiceal mass in 17 of 22 patients, 6 of the 61 patients underwent surgery, and in all of them the appendix removed was normal. The other 55 patients recovered with conservative treatment. In 26 a planned appendicectomy was cancelled because of the sonographic findings. Bacterial enteritis limited to the ileocaecal region (bacterial ileocaecitis) seems to be responsible for an appreciable number of unnecessary appendicetomies. It has characteristic sonographic features that distinguish it from appendicitis.

Six patients who developed acute appendicitis after surgical operations (cholecystectomy, choledocholithotomy, sigmoid resection, osteosynthesis of a hip fracture, abdomino-perineal resection) are described. The symptoms, signs and the results of investigations leading to relaparotomy are summarized. Possible causes of acute appendicitis after operation or trauma (luminal obstruction, bacterial infection, ischaemic changes and thrombosis) are discussed. As prevention is not possible, successful management of postoperative acute appendicitis includes an awareness of the complication and prompt surgical intervention.

The clinical usefulness of the preoperative determination of C-Reactive protein (CRP) in patients with suspected acute appendicitis was studied in 156 consecutive patients undergoing acute appendicectomy. The CRP values were found to increase with an advancing stage of the appendiceal inflammation found at operation and the length of the preoperative phase of illness. Eight out of 66 patients with a phlegmonous appendix found at operation showed no signs of bacterial infection, as revealed by an increased C-Reactive protein level. These results suggest that a preoperative quantitative determination of the C-Reactive protein in patients with suspected acute appendicitis might add a valuable parameter to the laboratory profile in this condition and can be used for the selection of those patients who would benefit from a preoperatively administered antibiotic prophylaxis. Furthermore, these results might support the theory that an obstruction of the appendix lumen is the most important factor in the genesis of acute appendicitis.

The symptom of lower abdominal pain in women is extremely common and does not always indicate the presence of serious illness. However, women with certain serious conditions such as pelvic inflammatory disease (PID), acute appendicitis, ectopic pregnancy and other complications of pregnancy may present initially with this symptom. Therefore, in managing women with lower abdominal pain care should be taken to exclude any serious condition before dismissing the patient. PID is a condition in which there is infection of the reproductive tract of women above the internal os of the cervix. This usually occurs as a result of an ascending cervical infection caused by Neisseria gonorrhoeae, Chlamydia trachomatis and anaerobic bacteria. The immediate and long term effects of PID include salpingitis, pelvic abscess, peritonitis, infertility and predisposition to tubal ectopic pregnancy. Women with lower abdominal pain should be assessed carefully and if PID is the cause they should be treated for gonococcal, chlamydial and anaerobic bacterial infection. Other gynaecological and surgical causes of lower abdominal pain and the immediate complications of PID require urgent referral to a specialist. PID is associated with significant morbidity and mortality.

Acute appendicitis represents one of the most common inflammatory diseases of the gastrointestinal tract. Acute appendicitis is most frequently based on the coincidence of obstruction, reduced blood supply, ischemic damage of the mucosa, and bacterial infection. Inflammation at other abdominal sites may also involve the appendix in 7% of cases causing periappendicitis. In 15-20% there are no pathologic findings of acute inflammation but rather post-inflammatory residues and a neuroma-like proliferation of Schwann cells, typically found in neurogenic appendicopathy. This finding may in part explain the clinical symptoms.

The frequency of acute appendicitis has fallen in the last three decades in developed industrialized countries. From 1961 to 1991 the number of appendectomies performed annually in Hungary decreased significantly. Since 1991 the numbers are essentially unchanged. Appendix lumen obstruction was formerly believed to be crucial in the etiology of the illness, while today mixed aerobic, anaerobic bacterial infection is considered more important. The inflammation process - according to immunogenetic differences - may lead to recovery or tissue necrosis and perforation. To date, no methods are known that could timely distinguish spontaneously healing or conservatively treatable appendicitis from those resulting in tissue necrosis, although routine usage of abdominal ultrasound technique is added to the clinical picture's modern diagnostic arsenal. The operative method for removing the appendix also has changed. Experience has confirmed that laparoscopic appendectomy is usually more favorable in the treatment of acute appendicitis than traditional surgery.

A 33-year-old man with a history of acute lower abdominal pain was admitted to the emergency room. After laparoscopic appendectomy and pathological confirmed acute appendicitis the patient developed thrombocytopenia and acute renal failure. Serological testing for hantaviruses revealed a positive result for PUUV IgG and IgM. Immunohistochemical work-up detected PUUV antigen in endothelial cells of capillaries and larger vessels. The high percentage of patients with hantavirus infection and severe abdominal pain is remarkable and, up to now, unexplained. To our knowledge this is the first report demonstrating PUUV antigen in the human intestine. Further studies are warranted whether hantaviruses are setting the stage for a secondary bacterial infection or cause an inflammation itself.

Facing a child with suspected acute appendicitis it is important to remind that a child is not a smaller adult. The main risk is to over-diagnose acute appendicitis in elder children and to misdiagnose it in preschool children and infants because it is less frequent, with early complications, and/or confusing symptoms in these age groups. Careful anamnesis and examination of the whole child--not only the belly--are mandatory. Biological findings of bacterial infection and US findings suggesting acute appendicitis are helpful. In doubtful cases the best help is offered by observation of the patient, symptoms and signs worsening necessarily in case of an acute appendicitis.
