Acute cholecystitis is a non-rare disease, the incidence of which was increasing in the last years parallel to biliary lithiasis, which in 90% of cases is the first cause of such pathology. From the anatomopathological standpoint, we distinguish three types of acute cholecystitis: catarrhal, suppurative and gangrenous. The most frequently remarked symptom is ache at right hypochondrium. Only in 30% of cases cholecyst can be palpated, in form of ovoid mass; typical is the positiveness of Murphy's manoeuvre; constant is fever, but not subicterus. The introduction of new methods of ascertainment, exempt from any risks, simple to be performed and remarkably careful, made the diagnostics of acute cholecystites easier: parietal cholecystotomography, hepato-biliary scintigraphy, echotomography (first approach investigation), computerized axial tomography and laparoscopy almost always succeed in dispelling doubts. By using more than one of these investigations, a diagnostic accuracy, touching on 100%, can be reached. The differential diagnosis should be placed with: peptic ulcer, acute pancreatitis, acute appendicitis, gonococcus perihepatitis, virus hepatitis, acute pyelonephritis, right basal pneumonia. The complications an acute cholecystitis can occur are: perforation (localized, in free peritoneum or in a hollow organ), choleperitonaeum, necrosis of hepatic parenchyma, acute pancreatitis. Due to the possible arising of such complications, the mortality unfortunately is not indifferent (5%), especially in patients already weakened by other chronic diseases. Still discussed is the question as to when performing operation. In fact, there are three trends: intervention in immediate emergency, in postponed emergency, or in remote time (preceded by a medical treatment). The Authors prefer the intervention in postponed emergency, as, in their experience, they remarked the poor effectiveness of the delay medical treatment, also involving a greater difficulty in the technical execution of the intervention and a longer stay in hospital. From 1973 up to 1983, 241 cases of acute cholecystitis (158 women and 83 men) were hospitalized at the First Aid Surgical Centre of the Catania University. Eight patients refused the surgical intervention. The remaining 233 underwent, depending upon the seriousness of the affection, the associated diseases and the different reactiveness to the medical treatment, operation: in immediate emergency (26.1%); in postponed emergency (67.8%; in remote time (6.1%). The mortality was 2.2%, with the lowest percentage in the second group.

Acute appendicitis is the first cause of emergency surgery in children. Actually, emergency abdominal sonography has evolved in differential diagnosis of acute appendicitis in children to differentiate it from other causes of acute abdomen as mesenteric lymphoadenitis, acute right pyelonephritis, acute diverticulitis in Meckel's diverticulum, intestinal intussusception, regional enterits, primary peritonitis, anaphylactoid purpura of Henoch-Schonlein. The aim of this study is the evaluation of the usefulness of abdominal sonography in diagnosing acute appendicitis in our current series of pediatric patients. We have operated 102 patients afflicted by appendicitis admitted to the pediatric department of Ospedale San Raffaele, Milano in a period of 5 years and operated on for appendectomy. In the last 2 years 36 patients were evaluated with abdominal sonography. This diagnostic tool showed in 34 (94.4%) a liquid effusion, sometimes thick of the right iliac fossa. In 2 patients the appendix had thickened layers, was edematous and the lumen was clearly filled with debris. Abdominal sonography has given a clear cut picture of the acute inflammatory process of the appendix. None of these patients has suffered from septic or obstructive complications. Mean duration of hospital stay was 6.35 days (3-15 days). Differential diagnosis of acute appendicitis can be extremely variable, from simple, paradigmatic situations to the most intriguing ones. This concept is well emphasized by William Silen when he says that "differential diagnosis of acute appendicits is an encyclopedic compendium of every abdominal disease that causes pain" in the 11th edition of Harrison's Principles of Internal Medicine.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute appendicitis rarely presents in the form or urinary tract symptoms. Atypical forms of acute appendicitis occur more frequently in subjects infected by the human immunodeficiency virus (HIV). The authors report a case of acute appendicitis in an HIV-infected subject mimicking acute pyelonephritis secondary to obstruction. Atypical forms of acute appendicitis must be diagnosed and treated as early as possible. Computed tomography plays an essential role in the diagnostic assessment of abdominal and lumbar symptoms in HIV-infected patients.

In 74,000 obstetrical patients at Los Angeles County Hospital the incidence of acute appendicitis in pregnancy was 0.05 per cent. In a study of 36 cases of clinically diagnosed appendicitis in pregnancy between 1956 and 1960, it was shown that the fetal and maternal morbidity and mortality were decreased when a definite operative procedure was done early. The difficulty in diagnosis is increased by the necessary consideration of pyelonephritis and twisted ovarian cyst. Rupture of the appendix increased hazards to maternal and fetal survival. It was noted also that threatened premature labor may indicate a ruptured appendix. Emergency operation with the use of antibiotics in such cases was effective therapy. The incidence of premature delivery was proportionate to the delay in operating. If operation was performed in less than eight hours after admission to the hospital, there was no maternal or fetal loss. A delay greater than eight hours resulted in a 17 per cent fetal loss in premature delivery and 4 per cent fetal loss of infants at term.

Several conditions can clinically mimic renal colic. We assessed the accuracy of non-contrast-enhanced helical CT and of ultrasonography (US) in offering an alternative explanation for flank pain. In a 3-year period, 181 patients with acute flank pain underwent US and non-contrast-enhanced helical CT in a blinded sequence. Their efficacy in detecting both alternative causes of pain and additional findings unrelated to the pain was assessed in 160 cases with a confirmed diagnosis. An alternative cause was found in 23 cases (14%). US gave 4 false-negative results (1 acute appendicitis, 1 ovarian cyst torsion, 1 diverticulitis, and 1 papillary necrosis) and 2 false-positive results (1 acute pyelonephritis and 1 diverticulitis), with a 78% sensitivity and a 98% specificity for nonlithiasic causes. CT gave 5 false-negative results (1 complicated ovarian cyst, 1 pleuritis, 1 epididymitis, 1 acute pyelonephritis, and 1 papillary necrosis) and 1 false-positive (1 simple ovarian cyst described as a complicated lesion), resulting in a 74% sensitivity and a 99% specificity for diagnosing alternative causes. There were 130 additional US findings in 68 patients and 151 additional CT findings in 77 patients. A wide spectrum of findings can be identified in subjects imaged for flank pain. Non-contrast-enhanced helical CT and US have comparable accuracy in diagnosing causes other than stone disease.

The aim of this study is to report the extrarenal computerized tomography (CT) findings in patients with acute pyelonephritis (APN). Twenty-one CT examinations of 20 patients [19 women and one man, with ages ranging from 18 to 57 years (mean -35.2 years)], presenting either with a clinical diagnosis of APN (n=17) or with a suspected acute appendicitis, fever of unknown origin, and adult respiratory distress syndrome, one in each, were retrospectively reviewed. None had a known preexisting systemic disease. Results showed that renal abnormalities were seen on CT in all patients. In addition, ascites was detected in all women patients associated with subcutaneous edema in five of them. A thickened gallbladder wall was found in 19 cases, all were women, and periportal tracking and a dilated inferior vena cava in 17 CTs. Pleural effusion and thickened interlobular septa were present in 16 and 15 studies, respectively. Relevant laboratory findings included hypoalbuminemia in 14, elevated liver enzymes in 11, hypocholesterolemia in nine, and elevated LDH levels in six cases. In conclusion, radiologists should be familiar with the extrarenal imaging features of APN that may be seen on CT, and on ultrasonography as well, and should look for renal abnormalities to diagnose a clinically unsuspected APN. Alternatively, APN should be included in the differential diagnosis of systemic diseases that cause gallbladder wall thickening to avoid misdiagnosing it as acute cholecystitis.

Ovarian vein thrombosis (OVT) is a rare cause of abdominal pain that may mimic a surgical abdomen. The differential diagnosis of OVT includes acute appendicitis, endometritis, pelvic inflammatory disease, pyelonephritis, nephrolithiasis, tubo-ovarian abscess, and ovarian torsion. The complications of OVT, including sepsis and pulmonary embolism, are significant. Diagnosis relies on a careful examination of the radiographic findings. This diagnosis should be considered not only in postpartum patients but also in women with pelvic inflammatory disease, recent abdominal surgery, malignancy, or known hypercoagulable state. In this report we present a case of OVT in a 29-year-old woman presenting with 3 days of sharp left-sided abdominal pain, nausea, and vomiting after bilateral salpingectomy. We then discuss the epidemiology, pathophysiology, and clinical management of OVT.

The differential diagnosis of right lower quadrate pain at the emergency department is quite perplexing. We describe a 38-year-old woman presenting with characteristic clinical and laboratory features of ruptured appendicitis with severe sepsis. However, contrast-enhanced computed tomography scan of the abdomen established the diagnosis of pelvic ectopic kidney with acute pyelonephritis. Antibiotic treatment eventually achieved satisfactory resolution without compromise of renal function. It is should be addressed that, even with the advent of modern imaging modalities, there can be a diagnostic pitfall in general practice when managing right lower quadrate pain in patients with typical presentations of acute appendicitis without sonographic evidence, as illustrated in this case. In conclusion, early recognition using exquisite imaging studies with raised awareness in the clinical setting and prompt antibiotic treatment can avoid unnecessary intervention, preserve renal function, and prevent a life-threatening catastrophe.

Acute appendicitis is a common surgical condition that is usually managed with early surgery, and is associated with low morbidity and mortality. However, some patients may have atypical symptoms and physical findings that may lead to a delay in diagnosis and increased complications. Atypical presentation may be related to the position of the appendix. Ascending retrocecal appendicitis presenting with right upper abdominal pain may be clinically indistinguishable from acute pathology in the gallbladder, liver, biliary tree, right kidney and right urinary tract. We report a series of four patients with retrocecal appendicitis who presented with acute right upper abdominal pain. The clinical diagnoses at presentation were acute cholecystitis in two patients, pyelonephritis in one, and ureteric colic in one. Ultrasound examination of the abdomen at presentation showed subhepatic collections in two patients and normal findings in the other two. Computed tomography (CT) identified correctly retrocecal appendicitis and inflammation in the retroperitoneum in all cases. In addition, abscesses in the retrocecal space (n = 2) and subhepatic collections (n = 2) were also demonstrated. Emergency appendectomy was performed in two patients, interval appendectomy in one, and hemicolectomy in another. Surgical findings confirmed the presence of appendicitis and its retroperitoneal extensions. Our case series illustrates the usefulness of CT in diagnosing ascending retrocecal appendicitis and its extension, and excluding other inflammatory conditions that mimic appendicitis.
