Appendicitis is not the only common cause of acute abdominal pain in childhood. Almost equally common is an acute episode which in its early stages resembles acute appendicitis but which subsides without treatment in 24 to 48 hours. The clinical features of this syndrome are contrasted with those of appendicitis. The two conditions cannot always be distinguished on clinical grounds, leading to admission to hospital for observation and the finding of a normal appendix in 14% of operations for suspected appendicitis. Reasons are given for abandoning attempts to diagnose acute mesenteric adenitis at the bedside.

Suppurative mesenteric lymphadenitis is so rarely encountered and its symptoms and findings so nonspecific tht it has not yet been diagnosed preoperatively. It seems to occur mainly in children between the ages of 3 and 13 years and presents in a manner suggestive of acute appendicitis. A palpable mass may further support this diagnosis (peri-appendiceal abscess) or encourage the consideration of other diagnoses such as lymphoma or inflammatory bowel disease. Even at laparotomy the diagnosis may not be immediately obvious. The organism is usually a haemolytic streptococcus, but a variety of other organisms have also been isolated. In the second case reported here, a pure growth of Staphylococcus aureus was obtained. Treatment consists of operative drainage with incidental appendicectomy followed by a course of the appropriate antibiotic. The postoperative course is usually uneventful and recovery rapid. The aetiology and mechanisms still have to be explained.

During early 1982, an outbreak of yersiniosis occurred in northern Mississippi. Abdominal pain suggestive of appendicitis was a common manifestation, but laparotomy revealed mesenteric adenitis. Yersinia enteritis should enter the differential diagnosis of acute appendicitis.

An infection with Yersinia strains may develop with the picture of acute appendicitis. Laparotomy will then not reveal an acutely inflamed appendix, but will often show mesenteric lymphadenitis or acute terminal ileitis. These conditions have been observed in four patients. The differential diagnostic possibilities are discussed. It is pointed out that acute terminal ileitis is practically never transformed into chronic terminal ileitis (Crohn's disease).

Both of tuberculous mesenteric lymphadenitis and tuberculous peritonitis are now rather rare in parallel with the decrease of the incidence of tuberculosis as a whole. Here, we report a case of tuberculous mesenteric lymphadenitis complicated with tuberculous peritonitis. A 28-year-old man was admitted to our hospital with pulmonary tuberculosis. Antituberculous chemotherapy was started and his chest X-ray findings were improved. After 11 weeks of the treatment, high fever of 39.0 degrees C developed suddenly and he complained right lower abdominal pain. During laparotomy performed on suspicion of acute appendicitis, swelling of mesenteric lymph-nodes, numerous miliary tubercles on mesentery and turbid ascites were noticed. Diagnoses of tuberculous mesenteric lymphadenitis and tuberculous peritonitis were confirmed by bacteriological and histological examinations of lymph-nodes and tubercles. Ileocecal resection was performed and clinical course after the surgery was favourable.

The potential advantages of laparoscopic surgery for a number of abdominal operations including appendicectomy have been heralded. In this study the aims were to assess prospectively the role of routine diagnostic laparoscopy in the diagnosis of acute appendicitis and determine the efficacy of laparoscopic appendicectomy. Patients with suspected acute appendicitis had diagnostic laparoscopy. When the diagnosis was confirmed laparoscopic appendicectomy was performed. Where an alternative diagnosis was made the appropriate treatment was instituted. If no diagnosis could be made the macroscopically normal appendix was removed by laparoscopic appendicectomy. Eighty-one patients (50 female, 31 male) had an initial diagnostic laparoscopy; 53 had appendicitis and proceeded to laparoscopic appendicectomy. A diagnosis could not be established at diagnostic laparoscopy in six patients and they also proceeded to laparoscopic appendicectomy. An alternative diagnosis was made in the remaining 22 patients (19 female and 3 male), with five proceeding to laparotomy and one patient with mesenteric adenitis having laparoscopic appendicectomy. Seven patients having laparoscopic appendicectomy required conversion to an open operation due to a retrocaecal or perforated appendix. The median operating time for successful laparoscopic appendicectomy was 55 min (range 30-95). Morbidity occurred in five of 53 patients having a successful laparoscopic appendicectomy. The median postoperative hospital stay was 2 days. The median time before return to normal activities was 8 days. Diagnostic laparoscopy is a useful diagnostic technique in women with suspected acute appendicitis, as it improves diagnostic accuracy, reduces the negative appendicectomy rate and avoids unnecessary laparotomy.(ABSTRACT TRUNCATED AT 250 WORDS)

High-resolution real-time ultrasound (US) with a 5 MHz transducer has proved to be an important method in the diagnosis of acute appendicitis. In a prospective study we examined 2074 unselected patients with suspected appendicitis to assess the diagnostic and epidemiological value of US. According to the clinical diagnosis females aged 10 to 30 represented the majority of suspected cases. Appendicitis was most often proved in male patients aged 15-30 years. The prevalence of acute appendicitis in childhood is lower (7%) than in elderly patients (33%). US enables the diagnosis of acute appendicitis with a sensitivity of 91%, a specificity of 98% and an overall accuracy of 97%. For differential diagnosis US demonstrates other diseases that mimic acute appendicitis. Thus it is possible to reduce the negative appendectomy rate particularly in children by revealing mesenteric lymphadenitis or terminal ileitis and in young women by directing attention to gynecological diseases.

A study to assess the reliability of clinical symptoms and signs in 50 patients with a presumptive diagnosis of acute appendicitis is presented. The male to female ratio was 3: 2, with age ranging from 2 to 15 years. Abdominal pain was present in 42; tenderness was localized in 35, generalized in 11 and diffuse in 4 patients. Total leucocyte count was above 11,000/cu mm in 31, below 11,000/cu mm in 17 and above 18,000/cu mm in 2. Of the 48 operated patients, 8 had normal appendices and the diagnosis in them was Meckel's diverticulitis 3, ruptured ovarian follicle 2, mesenteric adenitis 2, and salpingo-oophoritis 1. Abdominal pain and right iliac fossa tenderness with contributory investigations are the most reliable indicators of acute appendicitis with a false positive rate of 16.66% only.

Agenesis of the vermiform appendix is very rare. The incidence is estimated to be one in 100,000 laparotomies for suspected appendicitis. Several criteria have to be met before the investigator can conclude that the appendix is congenitally absent. This case is reported to bring this entity to the attention of surgeons who may encounter a similar situation during celioscopy. A 29-year-old patient was admitted through the emergency room with the chief complaint of abdominal pain. Acute appendicitis was suspected, and he was accordingly prepared for celioscopy. This report presents a patient with vermiform appendix agenesis diagnosed at celioscopy with concomitant mesenteric lymphadenitis. Agenesis of the vermiform appendix is very rare, and the diagnosis should not be made unless the ileocecal and retrocecal area are thoroughly explored.

Salmonella spp. infections can be particularly challenging when they manifest as acute abdominal problems and lead to emergency surgery. Examples of such serious conditions are Salmonella-related intestinal perforation, gallbladder involvement, salpingitis, and peritonitis. Mesenteric lymphadenitis associated with Salmonella typhimurium mimics acute appendicitis and can make it difficult to establish a timely and definitive diagnosis in young patients who present with right lower abdominal pain. Paralytic ileus is a fairly common manifestation of Salmonella infection at all ages, but complete intestinal obstruction requiring surgical intervention is very rare. Because of the nature of the diagnostic process, a significant number of patients with Salmonella infection present with acute abdomen and undergo needless operations. This report describes the cases of 2 pediatric patients who underwent surgery to address persistent pain in the right lower abdominal quadrant and complete intestinal obstruction, respectively. The first patient had inflamed mesenteric lymph nodes that caused appendicitislike symptoms, and the second had dense adhesions between the mesentery and the terminal segments of the ileum that led to intestinal blockage. Serology results showed that both patients' titers for BO ("B and O agglutinating [BO]") antibodies rose to 1:640 in the week after their admission to hospital, a pattern and level that is indicative of S typhimurium infection. J Pediatr Surg 36:1849-1852.
