The symptoms of right-sided renal colic mimic sometimes acute appendicitis. A prospective comparative study of 188 patients with ureteral stone and 188 patients with acute appendicitis was performed to evaluate the features of differential diagnosis. Appendicitis caused more often nausea (81 vs 11%), fever and localized pain in the McBurney (97 vs 59%) than renal colic. The patients with ureteral stone had tenderness in 16% in the right lower quadrant. The mean values of C-reactive protein (41 mg/l) and blood leukocytes (14 x 10(9)/l) were elevated in appendicitis, but not in renal colic (14 mg/l and 10 x 10(9)/ l). Urinanalysis revealed red cells in 92% of ureteral stones compared with 26% in appendicitis. Only one of 188 patients with appendicitis was first misdiagnosed to have renal colic. A mistake of appendicitis for ureteral stone is clinically rare occurring only once or twice per year in the hospital where 700-800 emergency appendectomies are annually performed.

Therapy for children with appendiceal abscess remains controversial. The authors present two such cases initially treated conservatively, without interval appendectomy, that later had recurrent appendicitis. An 8-year-old boy presented with fever, abdominal pain, and a right-lower-quadrant abscess (noted by ultrasonography). During laparotomy, the abscess was drained and the appendix was not found. He was lost to follow-up but returned 2 1/2 years later with perforated appendicitis. An appendectomy was performed, and image-guided drainage of a postoperative abscess was required. A 10-year-old girl presented with fever and right-lower-quadrant pain. Computed tomography showed a multiloculated mass. During laparotomy, the cecum was found to be densely adherent to the pelvic organs and bowel, so the surrounding abscess was drained. Interval appendectomy was refused. The patient returned 8 months later with recurrent acute appendicitis and an appendiceal abscess requiring appendectomy and drainage. Although initial drainage alone of appendiceal abscess is efficacious, the authors strongly advocate interval appendectomy as a critical component of the complete management of this entity.

A series of 16 children diagnosed as having a psoas abscess or deep iliac lymphadenitis seen over a 25-year period (1970-1994) is presented. 10 were treated conservatively while 5 were drained surgically and 1 percutaneously under imaging guidance. The presenting signs and symptoms may mimic the frequently seen entities, acute appendicitis and acute hip arthritis. Lower abdominal and inguinal pain, limp, fever and increased white count are common in all of these conditions. Accurate differential diagnosis is necessary to avoid unnecessary surgery due to a wrong diagnosis. Ultrasonography is preferred for diagnosis. Antibiotic therapy should be instituted immediately, aimed primarily at Staphylococcus aureus, the most common causative agent, although other organisms may be implicated. When a psoas abscess has been diagnosed, surgery and drainage are indicated. One of the preferred approaches is percutaneous drainage under imaging guidance. Convalescence is usually rapid and without late sequelae.

In a prospective study of 81 patients, the appendix was photographed during a laparoscopy performed for pain in the right iliac fossa. An appendicectomy was performed in 65 patients, for the remaining 16, another cause for the pain was found and the appendix was left in place. The evaluation of the photographed appendix was formed afterwards by a group of 10 surgeons and compared with the histopathological results. In 20 cases (30%) the appendix was normal. In 7 (10%) minimal mucosal inflammation was found and in 38 (60%) acute appendicitis. All the surgeons correctly recognised acute appendicitis. The accuracy of recognition of a normal appendix was 70% overall, and the maximum risk of leaving an early form of appendicitis to evolve was 14%. We propose not removing an appendix judged to be normal during laparoscopy if no other cause for the pain is found. A short course of antibiotics would cover the low risk of allowing a very early appendicitis to develop.

The incidence of appendiceal diverticulosis in pathologic specimens is 0.004-2.1%. Diverticular disease of the appendix is classified as congenital (true) or acquired (false). The clinical presentation differs from that of acute appendicitis. The average age is older, the pain is often intermittent, and while localized in the right lower abdominal quadrant, is of longer duration. No further treatment besides appendectomy is needed. Since a high rate of perforations, peritonitis and lower gastrointestinal bleeding have been reported as complications, it is recommended that in those with an incidental finding of diverticula of the appendix during surgery, that appendectomy be performed. It is not recommended to perform prophylactic appendectomy when diverticula of the appendix are found on barium enema.

Myositis of the truncal muscles can closely mimic acute appendicitis. Myositis is the early stage of muscular infection. It is characterized by diffuse muscular pain and swelling without a distinct mass. Early diagnosis of myositis improves the outcome and surgical debridement is usually avoided. Pyomyositis, the advanced stage of the disease, can be diagnosed by MRI examination. We present a case of early bacterial myositis that was diagnosed by MRI.

Our initial experience over the last 3 years with laparoscopic and thoracoscopic surgery in children and adolescents is reported. Between September 1992 and August 1995, a total of 215 laparoscopic and thoracoscopic procedures were performed: 32 appendectomies for acute appendicitis, 10 cholecystectomies for symptomatic gallstones, 11 procedures for adnexal pathology, 6 laparoscopies in children with nonpalpable testes, 3 diagnostic laparoscopies, and 153 thoracoscopic sympathectomies in children suffering from primary palmar hyperhidrosis. The post-operative course was uneventful in all cases. In 2 children with acute appendicitis we converted to the open technique due to technical difficulties. We are encouraged by the results of our initial experience. There is no doubt that laparoscopic cholecystectomy, laparoscopic surgery of adnexal pathology, and thoracoscopic sympathectomy, because of their numerous benefits - shorter operative time, hospitalization, and convalescence as well as less postoperative pain and improved cosmetic results - are replacing the open techniques. We are not convinced as yet of the advantages of laparoscopic appendectomy in children; we are presently performing both laparoscopic and conventional techniques and studying the various parameters in order to reach a more definite conclusion. Various other endoscopic surgical procedures will be carefully considered in the near future.

Torsion of an epiploic appendix is seldom diagnosed preoperatively because of the difficult differential diagnosis with other diseases causing acute abdominal pain, particularly appendicitis. The classic McBurney approach overlooks many infarcted epiploic appendixes. The use of diagnostic laparoscopy in acute abdominal pain can show an infarcted epiploic appendix to be at the origin of pain. Four patients were admitted for acute abdominal pain and moderate tenderness in lower quadrants and were operated on for suspected acute appendicitis. In all cases laparoscopy found the torsion of an epiploic appendix, which was resected, and a normal cecal appendix. Postoperative course was uneventful. In case of acute abdominal pain in the lower quadrants of suspected appendiceal origin, laparoscopy should be routinely performed not only in women but also in men to avoid overlooking other intraperitoneal diseases that can be the cause of symptoms.

Laparoscopic appendectomy (LA) is relatively a new technique and requires comparison to open appendectomy (OA) to determine the more favorable approach in the surgical management of acute appendicitis. We designed this study to compare the course and postoperative complications between LA and OA. We reviewed the charts of both groups of patients and followed their course in the hospital. Seventy-seven patients who underwent LA with one conversion to the open technique (1.3%) were compared to 84 patients who underwent OA. There was no difference in age and sex distribution. The mean hospital stay was shorter in the LA (32.5+/-10 vs 74.2+/-24 h, p < 0.0001). Parenteral analgesia requirement was higher in the OA group (4.7+/-1.4 vs 2.6+/-2, p < 0.0001). The total cost was higher in the OA group ($11,260+/-4000 vs 7,090+/-3500, p < 0.05). There was no significant difference in the OR time, duration of the procedure, and surgery costs between both groups. Normal appendices removed were similar in both OA and LA groups (23.8 vs 28.9%). There was no difference in the rates of postoperative complications between both groups. We conclude that LA is a viable alternative to OA. It is safe, cost effective, and less invasive than the OA with less pain and shorter hospital stay.

A case of extra-gastrointestinal infection by Anisakis in a woman living in Catania (Sicily, Southern Italy) is described. The patient complained of severe pain in the ileocecal region, and a diagnosis of acute appendicitis led to an appendectomy. During the intervention, a laparoscopic exploration showed a nodule on the large omentum that was surgically removed. Parasitological diagnosis was achieved on the basis of morphological observations carried out on the histological sections of the nodule.
