The authors describe the origin and the physiopathological events in acute appendicitis. They show an uncommon case of acute appendicitis. The aetiology was an opaque radiation foreign body causing a subacute abdominal disease. At operation the authors discovered the above body free in the abdominal cavity; the appendix was not in ischemic phase but completely cut off bycecal plant. They suppose aetiology to be of a decubitus origin.

In this paper we discuss the actual role of imaging in surgical management of urgency in colon-rectal pathology. We have considered four different kinds of pathologic: obstruction; occlusion; inflammatory and infections pathology; vascular pathology: In the first group an accurate radiologic evaluation in different decubitus is necessary. In negative or doubt cases, but with clinic highly suggestive for the presence of pathology, a CT examination is mandatory. In the second group, an accurate preliminary radiologic evaluation with plain radiographs of the abdomen is also necessary. With the use of contrast agents, it is possible to assess the level and the possible cause of the occlusion; at least, in some cases, (e.g. volvulus) a CT examination can be useful. The third group is concerning about inflammatory and infectious pathology: in these cases new radiologic technologies, like US and CT, play a significant role in their detection, evaluation of extension, assessment of complications. Especially in acute diverticulitis and acute appendicitis, the diagnosis is based essentially on clinical examination; and endoscopic confirmation is not possible in most cases. In all these cases, the radiologist can give to the surgeon an accurate evaluation of the pathology, with US or CT. The last group is about vascular pathology: at the moment angiography plays a secondary role in diagnosis, the use of endoscopy being more and more frequent; nevertheless, interventional radiologic procedures are successful in a lot of cases, thanks to their accuracy, low invasiveness and low percentage of complications.

The importance of prevention in late hematogenous infection is well understood but, because responsibility lies with general practitioners and other specialists, the orthopedic surgeon is usually not much interested. In both our and other countries, discussions are taking place on whether and to what extent antibiotic prevention should be carried out. Antibiotic prophylaxis of hematogenous infection is not indicated for all patients with joint arthroplasty, but only for a limited, defined group of patients at high risk. In these, however, the present state of knowledge suggests that prevention is necessary. A preventive treatment of late hematogenous infection is used for a procedure or a disease associated with risks in all the patients involved within two years of prosthetic joint implantation and, after this period, only in immunosuppressed patients. Surgery on the urogenital tract associated with the risk of bacteremia includes prostate gland surgery, operations for urinary bladder tumors, nephrolithotomy, extracorporeal lithotripsy and prostate biopsy. Certain conditions, such as urinary catheter presence, intermittent catheterization, urethral stent presence, urine retention and a history of urinary tract infection or prostate inflammation, pose an increased risk of bacterial colonization for the urogenital system. Dental procedures associated with a risk of bacteremia include tooth extraction, surgery on the parodontium, surgical extraction of an impacted tooth, dental implant treatment, procedures in a tooth's apical region, initial application of an orthodontic apparatus, intraligamentous blocks and also cleaning teeth and implants expected to bleed. Gynecological surgery with a risk of bacteremia are abdominal, vaginal and laparoscopic hysterectomies, surgery for cancer contaminated with vaginal bacteria, reconstruction surgery, operations on the pelvic floor for defects associated with urinary incontinence and use of xenotransplants. In obstetrics, a cesarean section carries some risks. In general surgery, the preventive administration of antibiotics is indicated, apart from situations always requiring antibiotic therapy, also for advanced forms of acute appendicitis, perirectal abscess, invasive endoscopy procedures on the colon, soft tissue phlegmona or abscess, surgical treatment of venous ulceration and pressure sores, and limb amputation. When inserting any piercing in patients with joint replacement at risk, it is recommended to do it with antibiotic administration; also, it is necessary to responsibly treat any inflammatory complication. The system of prevention for the late hematogenous infections of prosthetic joints is not developed as thoroughly as, for instance, it is in cardiology for patients with valve reconstruction. Because of the reasons given above, it is advisable to set up unambiguous guidelines for the prevention of late hematogenous infection in patients with joint replacement.

Hypogenesis or agenesis of right hepatic lobe is a rare abnormality and is generally associated with gallbladder and biliary tract abnormalities. Cases of biliary injury following cholecystectomy have been reported in patients with agenesis of right hepatic lobe because the anatomical anomalies complicate the surgical approach. We report a case of laparoscopic cholecystectomy in a patient with hypogenesis of right hepatic lobe. A 92-year-old male patient was admitted to our hospital with fever and right lower abdominal pain with suspected acute appendicitis. Abdominal computed tomography revealed gallstones with acute cholecystitis and hypogenesis of right hepatic lobe. He underwent laparoscopic cholecystectomy with the left semilateral decubitus position. The patient's postoperative course was uneventful. In conclusions, some patients with liver lobe hypoplasia do not present with the typical symptoms of acute cholecystitis due to dislocation of the gallbladder. The left semilateral decubitus position with modified placement of port sites is useful for laparoscopic cholecystectomy in patients with hypogenesis of right hepatic lobe.
