- Abstract
Purpose: The aim of this work was to compare the quality and noise of true non-enhanced (TNE) and virtual non-enhanced (VNE) images in patients undergoing dual-energy computed tomography (DECT) of the liver., Materials and Methods: Twenty consecutive patients (mean age 54.7±19.9 years) prospectively underwent abdominal DECT to assess the liver using a triphasic protocol consisting of precontrast, arterial-phase and portal-phase acquisitions. Exclusion criteria were allergy to iodinated contrast material, impaired renal function and a body mass index (BMI) >35 kg/m(2). The DE portal-phase acquisition was performed with automatic dose modulation (CARE Dose 4D). Nonionic iodinated contrast material (Iomeron 400) was administered at 0.625 gI/kg with a flow rate of 3.5 ml/s. Axial VNE images were reconstructed based on the portal data set using a collimation and an increment of 5 mm and were compared with TNE images reconstructed with the same parameters. The average image quality and noise were analysed by two radiologists in separate reading sessions., Results: No statistically significant difference (p>0.05) in image quality was observed between VNE (4.00±0.85) and TNE images (4.35±0.58). A sufficient diagnostic quality was found in 95.0% (19/20) of VNE images and in 100% of TNE images. No statistically significant difference (p<0.05) was observed in the average image noise of VNE (9.5±0.7) and TNE (12.3±1.1) images., Conclusions: Abdominal DECT allows acquisition of liver VNE images with similar image quality and lower noise than TNE. Nevertheless, a few technical limitations related to the small field of view of the second detector in patients with a high BMI and heterogeneous iodine subtraction restrict the application of this technique to selected patients only.

- Abstract
Purpose: This study was undertaken to estimate surplus radiation dose in retrospectively electrocardiography (ECG)-gated dual-source computed tomography coronary angiography (DSCT-CA) due to the slope-up and slope-down of the tube current using prospectively ECG-triggered tube modulation., Materials and Methods: We used an anthropomorphic phantom with an ECG-gated retrospective protocol and a DSCT scanner (Definition, Siemens). We used four tube current modulation algorithms: narrow pulsing window, with tube current reduction to 20% (A) and 4% (B) of peak current; and wide pulsing window, with tube current reduction to 20% (C) and 4% (D). Each algorithm was applied at five heart rates (HR=45, 60, 75, 90 and 120 bpm) with adaptive pitch values (0.2-0.5). Data sets were reconstructed in 5% increments from 0-95% of the R-R interval. Noise was measured at each R-R step in order to identify low noise (100% dose), medium noise (slope-up/down) and high noise (4/20% dose). Width of the transition window (slope-up/slope-down from 4/20% to 100% dose) was calculated. The surplus dose due to slope-up/slope-down was calculated., Results: Surplus dose was 19% (A), 34% (B), 14% (C) and 21% (D). The transition window lasted 10%+10% (slope-up + down) for HR <75 bpm and all HR in C (except for 120 bpm; 25%+15%), 15%+15% for HR >90 bpm (A). For C and D, instead, the slope-up increased with progressively higher HR (10%-25% of the R-R interval, except for 90 bpm, 10%), whereas the slope-down remained constant at 5% (except for 120 bpm; 10%)., Conclusions: The adaptive ECG-pulsing windows produced an increment of the surplus dose with increasing HR. The transition window was a constant source of surplus radiation dose in the range of 14%-34%.

- Abstract
In recent years, breast carcinoma diagnostics and therapy have evolved very considerably, allowing conservative surgery in most cases. These kinds of major operations have been greatly simplified since the introduction of the sentinel lymph node approach, with the possibility of a day surgery operation under local anaesthesia. The aim of this study, after thorough analysis of the axillary lymph nodes with ultrasound and cytological examinations, was to assess whether it would be possible to distinguish between negative and metastatic lymph nodes and whether the operation could be performed under local anaesthesia without hospitalisation. From January 2005 to January 2007, 54 breast carcinoma patients with negative axillary lymph nodes (after ultrasound examination) had a quadrantectomy and sentinel lymph node removal under local anaesthesia together with sedation where appropriate. Eight patients who presented micrometastases or isolated tumour cells in the sentinel lymph node underwent a subsequent lymphadenectomy. Our data show that, thanks to thorough analysis of the axillary cavity, it may be possible to use the sentinel lymph node approach with a good chance of the patient remaining free of distant metastases and of operating under local anaesthesia.

- Abstract
Purpose: This study was undertaken to evaluate the accuracy of 64-row computed tomography angiography (CTA) in the study of vascular anatomy by assessing the incidence of anatomical variations of the origin of the coeliac trunk, mesenteric arteries and collateral branches., Materials and Methods: Sixty patients were evaluated with 64-row CTA (VCT, General Electric Healthcare, Milwaukee, WI, USA) with a collimation of 0.625 mm after the injection of iodinated nonionic contrast material (4 ml/s). Exclusion criteria were the presence of any pathological condition likely to affect normal vascular anatomy., Results: The coeliac trunk had a normal trifurcation in 56.7% of cases. The common hepatic artery was normal in 60% of patients. The inferior pancreaticoduodenal arteries were either absent or not assessable in 8.3% of cases and there was a double trunk in 5%, a common trunk in 83.3% and a single vessel in 3.3%. The number of jejunal and ileal arteries ranged from a minimum of six to a maximum of 13 (mean value 8.7+/-1.34). The Riolan arcade was assessable in 31.7% and developed in 68.4% of these., Conclusions: The 64-row CTA enables visualisation of small vessels and accessory arteries that are difficult to identify with other techniques. The technique's high sensitivity allowed us to observe that the prevalence of vascular abnormalities is higher than that reported in the literature.

- Abstract
The diagnostic differentiation of breast lesions is very important because of the frequency with which they occur. Though fibroadenoma is easy to diagnose, some cases prove really hard to distinguish. Therefore, various methods have been suggested both for diagnosis and therapy, but no common approach has been achieved to date. We report our experience with 1350 cases diagnosed over a twenty-year period. The diagnosis was made on the basis of a diagnostic protocol drawn up over the years where cytology is of primary importance. With regard to therapy, we decide to operate when the cytological findings prompt the need for a histological examination of the lesion. Moreover, we operate on those cases where either an increase in size or a morphological change of the lesion has taken place. Histological examinations were carried out in 420 cases out of 1350 and only one of these cases turned out to be a carcinoma. As a result, the 0.24% error in the diagnosis can be considered irrelevant. In spite of the different therapies suggested (cryoablation, laser hyperthermia, i.a.), we believe that surgical treatment with local anaesthetic is the most suitable solution in those cases requiring treatment. Obviously, the diagnosis has to be accurate and made by surgeons with appropriate expertise. When the diagnosis is certain and the conditions of the lesion are stable, the best policy seems to be periodic follow-up.

- Abstract
A case of grade IV renal trauma is reported and the literature reviewed. A 29-year-old man was admitted in an emergency setting for a grade IV renal and splenic trauma as a result of a motorcycle accident. Since the patient was haemodynamically stable and the retroperitoneal haematoma was neither expanding nor pulsating, a conservative approach was adopted and the renal trauma was managed with interventional radiology. The case shows that major renal traumas can be usefully managed by non-operative treatment, necessarily consisting in a mutidisciplinary approach.

- Abstract
A multidisciplinary approach to severe polytraumatized patient is very important for a rapid, uncomplicated recovery. Specialized centres with special beds, monitoring equipment, and a multidisciplinary team are required. The authors report a case of a 26-year-old man admitted to their department in an emergency setting for a crush injury (occupational trauma) of the lumbar, gluteal and perineal areas, complicated with septic shock and gas gangrene of the injured areas. A multidisciplinary approach to the patient, consisting in surgical and plastic surgical therapy, hyperbaric oxygen therapy and the use of a special antidecubitus fluidized bed allowed complete recovery within 7 months without any motor or sphincter disorders.

- Abstract
A case of forearm compartment syndrome due to a minor trauma is reported. The severe clinical conditions due to a shock state lead to an initial misdiagnosis of clostridial myonecrosis. The patient, 68 y-old woman, was admitted to the intensive care unit of Authors' hospital for a traumatic injury of the right forearm. A diagnosis of gas gangrene due to clostridial myonecrosis was done and forearm amputation suggested. In spite of this indication a decompression fasciotomy of the forearm compartments was performed as well as a hyperbaric oxygene therapy. Since culture of necrotic tissue samples did not demonstrate any bacterial growth, the Authors decided to avoid amputation and perform a radial arteriovenous fistula to improve venous return and reduce distal edema and continuous bleeding, with a complete recovery within 40 days. Good evaluation of patient with suspected compartment syndrome means correct and not delayed treatment, avoiding invalidating outcome.

- Abstract
From 1992 to November 1999, 225 consecutive cases of acute abdomen were observed: 163 suspicious acute appendicitis, 7 ovarian cysts with suspect torsion, 4 intestinal occlusions, 1 digestive hemorrhage due GIST (Gastro-Intestinal Stromal Tumor), 1 case of hemoperitoneum after laparoscopic appendectomy and 49 cases of acute cholecystitis. In the 225 cases of emergency laparoscopic operations for acute abdomen the diagnostic accuracy has been of 99.5%, with only one case of conversion in to laparotomy for diagnosis. The conversion from laparoscopic to laparatomic surgical technique was registers in 2 cases (1%). The realimentation started in all the cases with a liquid diet as soon as 6 hours after the operation and with solid foods the following morning. The Authors haven't registered wound contaminations. The patients of working age rehabilitated in 8 days (between 7 and 21 days). In the athletic patients the average rehabilitation time was 15 days. On the base of the results obtained with their video-laparoscopy experience in acute abdomen emergency surgery, the Authors confirm that this technique can be advised as Emergency Surgery's first choice treatment.

- Abstract
Disadvantages related to CO2 pneumoperitoneum in high risk patients (anesthesiologic classification in III and IV ASA), have led to the development of the abdominal wall retractor, a device designed to facilitate laparoscopic surgery without conventional pneumoperitoneum. A case of a patient with acute cholecystitis, well-compensated liver cirrhosis, and high respiratory and cardiologic risk (ASA III class), submitted to laparoscopic cholecystectomy with gasless technique is reported.

- Abstract
A rare case of intestinal occlusion due to primary abdominal pregnancy is described. Laparoscopy revealed normal appendix and bowel obstruction by adhesion between the last ileal loop and cecum. The adhesion started from a neoformation (diameter 2 cm) localised on the mesenteric side of the ileum, about 30 cm from the ileocecal valve. A resection of the adhesion and dissection of the neoformation were performed. Laparoscopic procedures lasted 30 minutes. Histologic examination of the specimen revealed to be an ectopic pregnancy. The laparoscopic technique permitted to verify the diagnosis and perform the treatment of the abdominal pregnancy in absolute conditions of safety, maintaining the fertility of the patient (actually she is presenting a regular pregnancy).

- Abstract
Personal experience in a case of primary germinal tumor of the testis in advanced state is described. The initial treatment was chemioterapy: the patient received four complete cycles of cisplatin-based chemoterapy (PEB scheme). A surgical treatment consisted of a radical inguinal orchiectomy with high ligation of the spermatic cord at the deep inguinal ring associated with interaortocaval lymphonodes dissection. Actually, after two years from the beginning of treatment, the patient is well, without signs of neoplasm disease.

- Abstract
The authors report an uncommon gastric bleeding rate due to splenic hilum compression by a pancreatic cyst. The syndrome to be brought back to some sectorial portal hypertension form (left-sided portal hypertension) is difficult to diagnose because of absence of esophageal varices and other portal hypertension signs in an unchanged liver functionality patient. To put a correct diagnosis about gastric bottom bleeding varices without hepatic origin, the authors recommend to use arteriography and CT. Surgical treatment is proved to be the election one because of useless attempt of bleeding control through hepatic artery endoscopic sclerosis or embolization.

Through the latest acquired experience the importance of dissecting progressively the single layers of the atheroma plaque without arriving to a complete denudation of the arterial wall, so avoiding the risk of myointimal hyperplasia reactions, is outlined. The possibility of using endoarterial stents in case of more indaginous recanalization is also stressed.

- Abstract
Acute arterial obstruction of the limbs represents one of the most frequent events in Emergency Surgery. In 95% of the cases, the cause has to be searched in embolus parting from the heart in patients with rheumatic or fibrillary disease. Currently the two therapeutic methods used for peripheral arterial obstruction are thrombolytic therapy and surgical dysobstruction using Fogarty's catheter. The Authors compare the two methods on the basis of their experience in 129 cases underlying how the thrombolytic therapy (Urokinase, Streptokinase) should be instituted in the early hours from presentation of symptoms, otherwise, the possibility of revascularization will heavily drop. Better results are obtained by positioning a catheter under radiologic guide for intra-arterial infusion. The Authors also believe that up-to-date the surgical approach with Fogarty's catheter represents one of the best procedures, either for its feasibility of for the costs of the thrombolytic therapy. Furthermore, the thrombolysis may be not complete, and account for possible haemorrhagic complications.

- Abstract
The ingestion or introduction of foreign bodies is a common situation in emergency surgery. The patients who usually ingest foreign bodies for different reasons are children, psychotics, alcoholics, prisoners and old people. The authors analyzed 65 cases observed in the I Institute of Surgery of the University of Rome "La Sapienza": 45 males and 20 females. Both the anal introduction and ingestion may be accidental or voluntary. The incidence of complications is estimated about 5 to 7%. The authors underline the opportunity of a conservative removal through endoscopic procedures especially for intraesophageal corps. This procedure is recommended to reduce morbidity and mortality rates, as well as hospitalization and social costs.

- Abstract
In relation to their experience, the Authors affirm that currently an early diagnosis of breast cancer, in an absolute preclinical stage, is obtainable by adequate screening using specific methods especially among women who are at greater risk. Primary prevention is not achievable at present; however some considerations based on protocols which provide a surgical prophylactic therapy in high risk breast pathologies and in very selected patients, are possible. In the light of these considerations secondary prevention has a predominant role and may be more effective and curative if the treatment is carried out in the earliest stages of the disease.

- Abstract
The Authors report their experience in 38 cases (January 1990-Septembre 1994) of "difficult" gallstone disease of the main bile duct treated with electrohydraulic intracorporeal lithotripsy. Nineteen patients were affected with giant stones of the biliary tree, 6 with multiple stones of the main bile duct, 13 with stones of one or both hepatic ducts. The approach to the biliary tree was peroral transpapillary in 16 patients and transhepatic in the remaining 22. Twenty-five patients were previously submitted to surgery of the biliary tree (13 hepaticojejunostomy, 8 choledochoduodenostony, 4 papillostomy), while 5 had required a cholecystectomy, and 6 a gastroresection according to Billroth II. In 80% of the cases two lithotripsy sessions were enough to achieve the complete clearing of the bile duct. There was no mortality and morbidity was 5.3%. Total clearing was obtained in 97.4% of the cases. 6-48 months after treatment 37 patients still do not show clinical, laboratory or echographic signs of gallstone stasis or disease relapse.

- Abstract
Surgical infections represent one of the main causes of postoperative morbidity and mortality, especially in emergency surgery, with negative consequences on health costs. The Authors examined 2002 cases of emergency admission for surgical pathologies at the I Surgical Department of the University of Rome ¿La Sapienza¿ from 1987 to 1992. Overall septic complications were 13,7%, with a mortality rate of 1,2%. The Authors underline the lack in Italy of either an accurate system for monitoring septic complications or a useful method for data collection. At last the attention is focused on the main causes of septic complications, their diagnosis and treatment.

- Abstract
After reviewing current and past medical Literature regarding celiac axis aneurysms the case of a 70 year-old emphysematous patient with an aneurysm of the celiac axis measuring 6 cm in diameter is reported. The patient's pulmonary function testing status strongly precluded a surgical option. Angiographic embolization of the aneurysm was then performed. The Authors observed that embolization with immediate occlusion of all afferent vessels of the celiac axis leads to no serious short or long-term consequences as long as an adequate collateral hepatic circulation is maintained through the gastroduodenal and inferior pancreaticoduodenal arteries. This case would appear to be the first described in the Literature and the Authors hold this technique to be a valid alternative whenever a surgical procedure would be difficult or impossible to perform.

- Abstract
Approximately 80% of liver trauma cases have a good prognosis and do not create decision-making problems for the surgeon, while in the remaining 20% the correct choice still represents a problem. Recently there has been a trend toward more conservative surgical management with emphasis on hemostasis and debridement, as well as a move toward a non-surgical alternative (surgical abstention) where feasible, relying in such cases on first-line CT scans for trauma evaluation. We report 51 cases of liver trauma observed in the period 1985-1993 graded according to the AAST Liver Injury Scale as follows: 12 grade I lesions (23.5%), 7 grade II lesions (13.7%), 19 grade III lesions (37.3%), 7 grade IV lesions (13.7%), and 6 grade V lesions (11.8%). In managing these cases we relied on two first-line diagnostic procedures: diagnostic peritoneal lavage (DPL) and CT scans. DPL, performed on 10 blunt trauma victims with unstable vital signs, was positive in 7 who thus underwent immediate surgery, and negative in 3 who subsequently underwent CT scan. Another 14 blunt trauma victims with stable vital signs underwent first-line CT scanning. In the event of a CT grade III or IV lesion patients underwent surgery, while patients with a CT grade I or II lesion were followed expectantly. Deaths (14) occurred only among patients with grade III or IV lesions (including 9 multiple trauma victims) who underwent surgery.

A review of the literature, in fact, confirms the incidence of the disease is higher than usually believed. Therefore, a complete diagnostic evaluation is necessary to recognize the disease and assure the adequate treatment.

- Abstract
A prototype for the performance of mechanical thromboendarterectomy was constructed following various experimental designs and applications. The study was carried out on 25 aortobifemoral segments presenting typical obliterating arteriosclerotic lesions. The equipment consists of a flexible probe whose distal end was represented by a screened helical cutter and whose proximal end by an inlet and washing chamber. At the centre of these chambers and of the probe, a steel tube sets the cutter rotating at an adjustable speed. Good recanalisation was achieved in all vasal segments treated without damaging the vessel's wall. Although encouraging, results thus far are preliminary and require verification.

- Abstract
Underlining the importance of Profundus Femoral Artery and its capacity to make up for lower limb's haemodynamics during obliterative arteriopathy, the Authors conceive a funnel-shaped intravascular prosthesis, Goretex constructed (PTFE), to introduce, in case of obstruction, in the artery lumen with a suitable instrument. The research is performed through ten oldster dogs whose average weight is twenty-four kilograms. Isolated the deep Femoral Artery and carried out an arteriotomy of about two centimetres on the Common Femoral Artery, we bring the prothesis in Profundis Femoral Artery and we fix it to the wall of the Common Femoral Artery with 8/O microsurgical dots. After thirty days, the arteriographic test shows the patency of the endoprosthesis with normal peripheral flow in nine animals out of ten. By virtue of this preliminary experiment, the Authors point out the semplicity of this intervention, also feasible in local anaesthesia, the good tolerability of the prosthesis and its perfect integration with the surrounding arterious wall, without shifts or dissecting laminar flows between the external prosthesis wall and the vessel lumen of the animal.

- Abstract
In this study, the Authors have provoked experimentally acute pancreatitis in the rat by different methods, in order to find out morphological modifications of the pancreas in the initial stage of the disease. In case of biliary and pancreatic duct obstruction with pure pancreatic reflux, both oedema and inflammatory infiltrations were evident, whereas, in the presence of biliary reflux too, more serious histological features were detected. In conclusion, the first sign of alteration in acute pancreatitis could be represented by the association of intraductal hypertension and pure pancreatic reflux.
