The aim of our study was to further improve the preoperative diagnosis of acute appendicitis in children and adolescents. All diagnostic parameters from the patients' medical history (duration and quality of abdominal pain, stool behaviour), the laboratory (leukocytes, C-reactive protein), the clinic (defense, tenderness on percussion, nausea, vomiting, dry tongue) and repeated ultrasound investigations (visualisation of the appendix, indirect signs of an inflammatory process in the appendix region) were documented prospectively and were re-assessed with regard to their diagnostic value. As an additional parameter, procalcitonin was determined. 1156 patients (593 male/563 female) with a mean age of 9.51 years (+/- 1.2 yrs) (max. 15 yrs/min. 2.3 yrs), referred to the department with acute abdominal pain, were examined. 233 (141 male/92 female; 20.1 %) of these patients with a mean age of 10.47 years (+/- 1.1 yr) had appendicitis. Based on the patients' medical history, laboratory findings, the initial clinical investigation and the initial ultrasound investigation, 173 patients (74.3 % of the later operated 233 children with appendicitis) were diagnosed with certainty. The diagnosis of 60 patients (25.7 %) of this group remained uncertain. These patients received a saline enema (Clysmol, Pharmacia & Upjohn Company) and were subjected to a second clinical and sonographic investigation after approximately four hours of parenteral fluid substitution (Ringer's lactate, Mayrhofer Pharmazeutika Company, 4 ml/kg/h). The other 923 patients (79.83 %) were discharged and were followed up as outpatients in the following days. Based on this stepwise procedure, the percentage of correctly diagnosed appendicitis could be increased to 97.4 %. The measurement of procalcitonin proved to be of no value in the diagnosis of acute appendicitis. It may be concluded that in children with abdominal pain, high diagnostic accuracy can only be achieved by a carefully combined evaluation of all individual diagnostic parameters and repeated investigations.

Gastrointestinal stromal tumors (GISTs) are characterized with diverse clinical presentations, including acute and chronic gastrointestinal bleeding, abdominal pain, presence of an intra-abdominal mass, anorexia, and intestinal obstruction. A 60-year-old obese woman presented as an acute abdominal emergency with right lower quadrant (RLQ) pain and tenderness, nausea and leukocytosis, all mimicking acute appendicitis. Laparotomy revealed a spontaneously ruptured GIST of the jejunum, which was localized to the RLQ due to postoperative adhesions following previous two cesarean sections and cholecystectomy. Complete surgical resection was performed, followed by an uneventful early postoperative course.

We reviewed the medical records of 62 patients with systemic small and medium-sized vessel vasculitides and gastrointestinal tract involvement followed at our institution between 1981 and 2002. This group included 46 men and 16 women (male:female ratio, 2.9), with a mean age of 48 +/- 18 years. Vasculitides were distributed as follows: 38 polyarteritis nodosa (21 related to hepatitis B virus), 11 Churg-Strauss syndrome, 6 Wegener granulomatosis, 4 microscopic polyangiitis, and 3 rheumatoid arthritis-associated vasculitis. Gastrointestinal manifestations were present at or occurred within 3 months of diagnosis in 50 (81%) patients and were mainly abdominal pain in 61 (97%), nausea or vomiting in 21 (34%), diarrhea in 17 (27%), hematochezia or melena in 10 (16%), and hematemesis in 4 (6%). Gastroduodenal ulcerations were detected endoscopically in 17 (27 %) patients, esophageal in 7 (11%), and colorectal in 6 (10%), but histologic signs of vasculitis were found in only 3 colon biopsies. Twenty-one (34%) patients had a surgical abdomen; 11 (18%) developed peritonitis, 9 (15%) had bowel perforations, 10 (16%) bowel ischemia/infarction, 4 (6%) intestinal occlusion, 6 (10%) acute appendicitis, 5 (8%) cholecystitis, and 3 (5%) acute pancreatitis. (Some patients had more than 1 condition.) Sixteen (26%) patients died.The respective 10-month and 5-year survival rates were 71% (95% confidence interval [CI], 52-90) and 56% (95% CI, 35-77) for the 21 surgical patients; and 94% (95% CI, 87-101) and 82% (95% CI, 70-94) for the 41 patients without surgical abdomen (p = 0.08). Peritonitis (hazard ratio [HR] = 4.3, p < 0.01), bowel perforations (HR = 5.7, p < 0.01), gastrointestinal ischemia or infarctions (HR = 4.1, p < 0.01), and intestinal occlusion (HR = 5.5, p < 0.01) were the only gastrointestinal manifestations significantly associated with increased mortality in multivariate analysis. For this subgroup of 15 patients, 6-month and 5-year survival rates were 60% (95% CI, 35-85) and 46% (95% CI, 19-73), respectively (p = 0.003). None of the other gastrointestinal or extraintestinal vasculitis-related symptoms, or angiographic abnormalities (seen in 67% of the 39 patients who underwent angiography), was predictive of surgical complications or poor outcome. However, prognosis has dramatically improved during the past 30 years, probably owing to better management of these more severely ill patients, with prompt surgical intervention when indicated, and the combined use of steroids and immunosuppressants.

An unusual cause of acute abdominal pain simulating acute appendicitis is presented. The patient was admitted with complaints of fever, malaise, headache, nausea, vomiting, diarrhoea, and severe bleeding. Based on the clinical and epidemiological findings, a diagnosis of Crimean Congo hemorrhagic fever virus infection was suspected, and ribavirin therapy was started. While her clinical condition was improving, she experienced a sudden pain at her right lower quadrant of the abdomen. Explorative laparotomy revealed haemorrhage within the abdominal muscles. Her CCHF IgM was found to be positive.

Appendectomy for appendicitis is one of the most common procedures performed in the United States. Residual tissue left after an initial appendectomy risks the development of stump appendicitis. A comprehensive review of the English-language literature revealed 36 reported cases of stump appendicitis. Typically, patients present with signs and symptoms similar to acute appendicitis; however, due to prior surgery, the diagnosis is difficult and the rate of appendiceal stump perforation is extremely high. Herein, we present a case of a 32-year-old female presenting with right lower quadrant pain, nausea, and fever 5 months after laparoscopic appendectomy. Upon surgery, an appendiceal stump was discovered.

Appendicitis has rarely been reported following solid organ transplantation and never following liver transplantation. We reviewed records of all patients who received solid organ transplants at UCLA between 1989 and 2002 and subsequently underwent appendectomy for presumed acute appendicitis. Of nearly 8000 transplant patients, 17 (nine male, eight female) subsequently underwent appendectomy for presumed acute appendicitis. Average age at appendectomy was 37 yrs (range 6-73 yrs). Organ transplants included liver (seven patients), heart (four), kidney (three), kidney-pancreas (two), and heart-kidney (one). The mean interval from transplant to appendectomy was 1064 d (16-2977). Presenting symptoms and signs included abdominal pain in 16 patients (94%); nausea and or vomiting in 15 (88%); right lower quadrant tenderness in 16; and leukocytosis (WBC > 10 000) in 13 (76%). Mean interval from presentation to appendectomy was 0.94 d (range 0-4). Computed tomography (CT) was performed in 16 patients and showed signs of acute appendicitis in 15. Open technique was used in all patients, preceded by laparoscopy in one. Pathology showed appendicitis in 15 patients (one with perforation), serositis in one, and a normal appendix in one. Mean duration of hospitalization was 7 d (range 1-20). Complications occurred in four patients (24%) and included intra-abdominal abscess requiring percutaneous drainage, ventral hernia, small bowel obstruction, and hematuria in one patient each. There were no deaths and no cases of acute rejection during hospitalization. Average length of follow-up was 712 d (range 3-2492). We conclude that appendicitis is relatively rare following solid organ transplantation. CT facilitates prompt diagnosis. The clinical presentation is similar to that of non-transplant patients, but complications are more frequent, and hospitalization is longer.

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.

This study has been performed in the Emergency center, Clinical centre of Serbia, during the period 01.03.2007-01.09.2007. We performed this study on 57 patients with diagnosis suspected for acute appendicitis (ages 16-70). Parameters that make the Alvarado score are the following: migration of pain, anorexia, nausea or vomiting, right lower abdominal quadrant tenderness, rebound tenderness in right iliac fossa, elevated temperature, leukocytosis, shift to the left of neutrophils. The aim of the work is to evaluate the Alvarado scoring system in diagnosis of the acute appendicitis. With all the patients Alvarado score has been determinate preoperatively, and diagnosis was confirmed by intraoperative finding and histopatological examination of the removed appendix. All the patients with score 7 or more were surgically managed. Specificity (positive predictive value) was 92.59 % in males and 76.67 % in females. The negative appendectomy rate was 7.41 % with the males and 23.33 % with the females. The values of the Alvarado score are significantly higher in the patients with acute appendicitis, compared with the patients of the other diseases. With the application of the Alvarado scoring system we can decrease postoperative morbidity and mortality.

Jejunoileal diverticulosis is a rare entity. Jejunoileal diverticulosis is not a disease that surgeons see often in clinical practice; however, it should remain on the differential diagnosis for any patient with an acute abdomen or gastrointestinal bleeding of unknown origin. It can present with a wide range of clinical scenarios and when patients experience chronic symptoms such as bloating, abdominal pain, nausea, bacterial overgrowth, or malabsorption, medical therapy is successful in most patients. However, when patients present with acute symptoms of bleeding, inflammation, perforation, or obstruction, surgical resection and primary anastomosis is often the treatment of choice. If patients are asymptomatic, they are better left alone, even when discovered incidentally in the operating room. In closing, the possibility of a patient having jejunal diverticular disease should be suspected whenever the symptoms of obscure abdominal pain, anemia, dilated jejunal loops on abdominal radiographs, a history of colonic diverticuli, and a history of acute appendicitis.

Appendicolithiasis is a condition characterized by a concretion in the vermiform appendix. Appendicoliths are found in 10% of patients with acute appendicitis, but they are seen more frequently in perforated appendicitis and in abscess formation. We herein report a case of acute appendicitis due to appendicolithiasis, which mimics acute disorders of the genitourinary tract and causes diagnostic confusion. A38- year-old man presented to our emergency department with a history of intense, acute, recurrent, crampy right lower quadrant pain radiating to the right groin region, accompanied by nausea. Physical examination revealed muscular defense and rebound tenderness in the right lower quadrant, tenderness in the line of the right ureter and right costovertebral angle tenderness. On X-ray examination, a right kidney stone was identified as was an incidental 3-cm density in the right lower quadrant. The patient underwent appendectomy. The diagnosis was made by operation and also X-ray examination of the appendectomy material showing appendicolithiasis. Acute appendicitis may manifest as a variety of genitourinary disorders. The possibility of an appendicolith with or without acute appendicitis must always be considered in the differential diagnosis of acute lower abdominal and pelvic disorders, and in the consideration of common acute urological disorders.
