The biliodigestive fistula is not a rare affection in the context of acute pathology of the gastrointestinal tract. It often affects patients between 63 and 85 years old , particularly the female sex, and the most common cause is acute or chronic cholecystolithiasis. Open issues are the delayed in the pre-operative diagnosis, and controversies exist regarding the best surgical approach. The choice of treatment options is influenced by the age of the patients and their clinical conditions and also by the presence of comorbidities and of a delayed right diagnosis. In the 1 to 3% of cases, the biliodigestive fistula presents a gallstone ileus as complication, whose diagnosis is particularly difficult for the lack of specific signs and symptoms. The contrast-enhanced CT is considered the gold standard for a specific pre-operative diagnosis, as it directly shows the fistula. Surgical treatments include one-stage procedure or two-stage procedure. Many studies seem to favor a deferred definitive procedure. The Authors describe 4 cases: in 3 cases, women between 70 and 80 years old presenting an history of recurrent cholecystitis, in 2 cases, and in 1 case presenting a bowel obstruction; in 1 case a 50-years-old man, with no significant past medical history, presenting a bowel obstruction. The Authors have performed in the 2 cases of gallstone ileus an enterolithotomy with cholecysto-duodenal fistula repair and cholecystectomy, in one-stage, and this has been possible because of the good clinical conditions of the patients and their low operative risk. In the case of fistula without the complication of gallstone ileus, the treatment approach has been cholecysto-gastric fistula closure with a gastroplastic using separate stitches and cholecystectomy, in one-stage. We are in agreement with data in the literature regarding the delay into the diagnosis of biliodigestive fistula and with the importance to suspect it or gallstone ileus presence, although the clinical presentation is extremely non-specific. In our experience, cholangiopancreatography-CT and CECT have made easier the pre-operative diagnosis and so reducing the delay of the treatment.

Several studies have demonstrated the clinical and technical benefits of the laparoscopic surgery for complicated and uncomplicated appendicitis. Our retrospective study included 12 patient who underwent SILS appendectomy (SILS-A), 14 who received conventional laparoscopic surgery (VL-A), and 12 who received laparotomic appendectomy (OA); performed in all cases by the same surgeon (C.F.). The aim of this study was the comparison between this three different surgical techniques on same features: post operative leukocytosis, post operative pain, need abdominal drainage, esthetic viewpoint, incidence of complication, hospital stay. The results showed no significant differences between SILS-A and VLS-A, while an evident improvement shows versus O-A, even though not statistically significative. SILS was more effective in decreasing the risk of postoperative wound infection.

Cardiac resynchronization therapy (CRT) can be considered as an established therapy for patients with moderate or severe heart failure (HF), depressed systolic function and a wide QRS complex. Biventricular stimulation through the CRT is applied at patients with an intra and/or inter-ventricular conduction delay. The goal of this technique is to resynchronize contraction between and within ventricles. A numerical model of the cardiovascular system, together with the numerical model of the biventricular pacemaker (BPM), can be an useful tool to study the better synchronization of the BPM in order to reduce the inter-ventricular and/or intra-ventricular conduction delay.Within a group of patients which were representative of the most common disease etiologies of heart failure, seven patients, affected by dilated cardiomyopathy undergoing CRT with BPM, were studied and simulated using the numerical model of the cardiovascular system CARDIOSIM. The patients were submitted to echocardiographic evaluation (with pulsate Doppler and tissue Doppler imaging) and electrocardiography evaluation in order to evaluate intra-ventricular and/or inter-ventricular dyssynchrony. These evaluations were made three times: the first one before BPM implantation, the second and the third one respectively within seven days and six months after BPM implantation. Also haemodynamic parameters were measured. Using the software simulator, the pathological conditions before CRT, within seven days and within six months since CRT were reproduced for each patients in order to evaluate the following haemodynamic parameters: the end-systolic and end-diastolic left ventricular volume, the systolic pulmonary arterial pressure, the systolic, diastolic and mean aortic blood pressure and the ejection fraction. Also the trend of the left ventricular elastance was studied for each patient in order to evaluate the benefits produced by the CRT.The results obtained by means the numerical simulator were in good agreement with clinical data measured on the patients. For each patient also the evolution of the left ventricular elastance was in accordance with the literature data.The cardiovascular numerical model seems to be a useful tool to study the synchronization of the BPM in order to reduce the inter-ventricular and/or intra-ventricular conduction delay and to reproduce the condition of a patient.

This study was undertaken to compare the efficacy, side effects and patient acceptance of standard 4-liters polyethylene glycol (PEG) and 2 doses of sodium phosphate (NaP) solution for precolonoscopy colon cleansing.A total of 182 patients were randomized to receive either standard 4-L PEG (88 patients) or 80 mL of NaP (94 patients) in a split regimen of two 40 mL doses separated by 24 h, prior to colonoscopic evaluation. The primary endpoint was the segmental assessment of colonic wall visualization. Secondary outcomes included percent of assumed preparation, and the patient tolerance and acceptability.A significantly higher completion rate was found in the NaP group compared to the PEG group (84.3% vs 62.9%; difference, 21.40%; 95% confidence interval [CI], 8.29% to 34.51%; p = 0.001). PEG solution caused more nausea than NaP solution (p = 0.024). Patient acceptance for bowel preparation with NaP was greater (p = 0.019). Adequate colon wall visualization was achieved in similar proportion of patients in both groups with exception of the descending colon, where NaP regimen was superior (72.0% vs 52.9%; difference, 19.10%; 95% CI, 5.20% to 33.00% ; p = 0.012).Two doses of NaP solution, taken 24 h and 12 h before colonoscopy, tend to guarantee superior results in colonic cleansing with respect to standard 4-liters PEG solution. Taking the second dose of NaP 24 h after the first dose reduces side effects and allows achieving a more satisfactory compliance of the patient.

Hepatocellular carcinoma (HCC) is the most common malignancy of the liver and the third most common cause of cancer mortality worldwide. The major risk of developing HCC is associated with HBV and HCV hepatitis. Liver transplant (LT) is the gold standard for "small" HCC (HCCs) in Child-Pugh class A cirrhotic patients. However its use has been restricted by the severe shortage of donors, so that hepatic resection (HR) is often performed in these patients. In the last two decades image-guided interventional catheterization and ablative regional treatment procedures have revolutionized the therapy of unresectable primary and secondary liver tumors. The Authors present a case of a 61-years old man with Child-Pugh class A HCCs. The age and the previous history of bladder carcinoma made the patient not suitable for LT. The patient refused HR so that transarterial chemoembolization combined to thermo-ablation therapy and oral intake of tamoxifen were proposed. Patient's tolerance to the treatments has been good. During 11-year follow-up there was earlier intrahepatic progression of the tumor followed by reduction in size and number of the lesions. In spite of the scarce prognosis, chemoembolization and immunotherapy allowed to achieve a satisfactory local control of disease in our patient and guaranteed a good quality of life at long-term follow-up.

The Authors report a rare case of a 57 years old man affected by a left radial nerve schwannoma that occurred as an asymptomatic lesion of the axilla. At clinical examination the lump was undistinguishable from the most common axillary lymphadenopathy. A lymphoadenopathy was erroneously diagnosed with ultrasonography (US). This mistake was due to the low specificity of the instrumental methodology and to the rarity of an asymptomatic schwannoma of the infraclavicular brachial plexus. The neoplasia was excised without using the microscope. In the early post-operative follow up, a "falling" attitude of the wrist, the hand and the fingers appeared, peculiar for a lesion of the radial nerve. Furthermore a hypoaesthesia of the skin of first finger and of the first interosseus space was associated. The sensitive and motor electromyography showed a radial nerve suffering. The "stupor" of the nerve trunk was treated with steroid therapy for 7 days and the patient underwent to some series of neuro-rehabilitative physical therapy for 12 weeks. The postoperative total body CT, showed that the lesion was unique: therefore it was possible to exclude the diagnosis of neurofibromatosis. After 28 months electromyography and axillary US were performed showing the complete resolution of the motor and sensitive deficit and the absence of local recurrence.

The management of traumatic retroperitoneal haematomas is still a much debated question. Although the diagnosis has become easier using CT with contrast medium, the therapeutic decisions are still difficult because of the great variability of the lesions, which may be simple but very often complicated. Our study is based on 1086 treated patients, 29.5% of the 3682 critical abdominal polytrauma seen in 35 years. Mortality has been 12.9% with a medium ISS (Injury Severity Score) of 23.4. 71.4% of the cases were closed traumas, 28,6% were open traumas. The most common single lesions have been pelvic (43%), followed by the renal traumas (39%). Regarding the associated lesions, the thoracic traumas cause an increment of the ISS score up to 26.2% and of mortality up to 14.6%. The maxillofacial traumas associated with traumatic retroperitoneal haematomas represent 11%, mainly associated with motorcycle accidents, which have increased in the last years from 2,4% in the 70s to 32% these days. Our approach to these patients has been basically conservative. Following the indications obtained by the CT, we widely used interventional angiography, especially for renal lesions and, after pelvic stabilization, for pelvic haematomas. We have chosen surgery considering the kind of traumas (open or closed), the location of the haematoma and especially, the clinical course of the patient's hemodynamic condition.

There have been millions of people found to have AIDS. Death rates from AIDS have declined 15% to 20% in the past 5 years. However, nearly 75000 people will die with AIDS in this year. Patients with AIDS are also at risk for developing both Aids-defining cancers, such as Kaposi's sarcoma and non-Hodgkin lymphoma, and non-Aids-defining cancers and opportunistic infections. In patients with advanced Aids, the Cytomegalovirus is a frequent cause of chorioretinitis, pneumonitis, chronic perineal ulcerations and oesophagitis. It has been involved in endocrine, bone marrow, central nervous system and kidney abnormalities. CMV infection of the small bowel accounts for only 4.3% of all cytomegalovirus infection of the GI tract (large bowel 47%, duodenum 21,7%, stomach 17,4%); isolated cases of small bowel perforation due to CMV have been reported in AIDS patients, and all but one patient died. The Authors report a rare case of an HIV-positive young man with gastroenteric Cytomegalovirus infection responsible for generalized peritonitis from multiple perforations.

Authors report their initial experience in surgical treatment of thyroid diseases in an area with high percentage of thyroid tumors. Since January 2006, we examinated 428 patients. By clinical features, hormonal profile, imaging and US-guided FNAB, we selected 134 of them for surgery; 93 patients underwent thyroidectomy in January-November 2006. The Authors analyse therapeutic choises and surgical techniques, stressing the high percentage of thyroid neoplasms.

The femoral hernia can be defined as infrequent, and predominantly found in females, with the highest incidence between 30 and 40 years of age. It shows a high tendency to strangulation, also up to 40% of cases, due to the presence of the Gimbernat ligament, which with its tense fibrous margins, aids strangling known as "raised crest". The diagnosis may not be easy, overall in the clinical presence of acute abdomen in elderly patients, disabled people or people who are uncooperative during physical examination. Therefore, it should be sought with an adequate bilateral exploration of the region in all occlused patients and especially with the use of radiological images of the small intestine. The solution currently practiced is prosthetic, proposed by Lichtenstein, and variously modified by Gilbert, Rutkow, Bendavid, and other which uses a prolene plug in the shape of a cigar, umbrella, or basket, according to the size and characteristics of the parietal defect. In emergency conditions, the technique doesn?t change; but if there is stercorary contamination, it is advisable to use direct repair according to the old method of Bassini. In the last 10 years, we have treated 37 femoral hernias in emergency, using direct repair in only 2 cases. In 3 cases we used PTFE; in the other 32 cases prolene was always used; 20 patients were operated under local anesthetic, 12 under general anesthetic and 5 under peridural anesthetic. Satisfactory results were achieved, with average hospital recovery time of 1.4 days, with an early recovery between 3 and 5 days, with only 2 relapses.

We present a case of sigmoid colon injury after blunt abdominal trauma. The patient was submitted to sigmoid resection with primary end-to-end colo-colic anastomosis. He died 22 days after operation with septic shock and acute respiratory failure. Post-mortem examination showed left lung generalized pneumonia with no signs of intra-abdominal pathology; colo-colic anastomosis was intact. We reviewed the literature about the management of this rare trauma.

Diverticulitis of the right colon is a rare disease in the Western countries, so that the diagnosis still remains very difficult and frequently indistinguishable from acute appendicitis preoperatively. In presence of acute abdominal discomfort with pain referred to the right lower quadrant region, fever and hyperleukocytosis, nausea and vomiting, surgeons operate with a margin of uncertainty, because of the increased morbidity and mortality associated with delay in diagnosis and consequent perforation of acute appendicitis. Moreover the unexpected inflammatory colonic mass of uncertain etiology is sometimes mistaken for carcinoma at laparotomy and consequently a right hemicolectomy is performed. In these cases it should be better that right-sided colonic diverticulitis should be taken into account allowing a more correct surgical approach and even conservative treatment alone. Therefore, in case of suspected appendicitis, since our experience and literature data indicate that the mean age for right diverticulitis is over 40 years, also in presence of a significative Alvarado's score, computed tomography is strongly recommended, if the age is over 40 years.

The Authors studied 30 cases of diaphragmatic traumatisms from 1972 to 2003 to stress the difficulty to achieve an early diagnosis and the need of their immediate treatment: 26 of these patients were male and 4 female (6.5:1); the pathogenesis was in 50% of cases an open trauma and in 50% a closed trauma. The mean age was 36.6 years (33.4 in the open trauma and 41.4 in the closed). The left hemi-diaphragm was affected more frequently (63%) than the right (37%). The associated lesions were mainly of the parenchymatous abdominal organs (spleen 43.3% and liver 49%), while in the thorax lung was involved in 20% of cases and heart in 3.3%. All patients underwent plastic surgical intervention of the diaphragm. In only one case, particularly severe, the operation consisted in placing a pleuric drain and death occured a few hours later. Mean mortality was 30% (33.3% in open and 26.6% in closed traumas) and mean hospital stay was 36.2 days. Accurate diagnosis in emergency is difficult because of the frequent associated lesions, typical of these patients. Despite of the optimisation of the rescue and the new imaging technologies, the gold standard for treatment is not yet reached. There is still a considerable amount of misdiagnosis, a relevant mean hospitalization, a high mortality and a very high morbidity. The best approach to thoraco-abdominal traumas is still to fear a diaphragmatic lesion up to contrary demonstration, in order to achieve precocious diagnosis and surgical treatment, to avoid complications of delayed treatment.

Small bowel tumours are relatively rare neoplasms; unusual occurrence associated with nonspecific symptoms, and low-sensitivity tests availability, are responsible for diagnostic delay. A retrospective study was performed on 42 cases with acute presentation, from 1972 to 2001; median age was 52 years (range 14-79) and there was a slight female prevalence (57.1% vs 42.9%). The most common acute presentation was occlusion (57.1%), followed by gastrointestinal (GI) bleeding (23.8%), perforation (14.3%) and occlusion/perforation (4.8%). Benign neoplasia were 38.1% (16 cases) and adenoma is was the most common type; malignant forms were 61.9 (26 cases) and adenocarcinoma and lymphomas were the most common histotype. Radical surgical procedures were possible only in 57% of malignant forms (24 patients); morbility was 4.8% (2 cases: 1 anastomotic dehiscence and 1 subphrenic abscess); mortality was 14.3%. From our retrospective study, we can state that survival for malignant lesions is strictly dependent of early TNM staging and possibility of radical surgical procedure. An extremely high index of suspicion in evaluating mild and often misleading symptoms, integrated with specific diagnostic studies, should be the proper approach. Prognosis for benign from is excellent in all cases.

Although endoscopic injection therapy is an effective method for bleeding peptic ulcers, it is associated with significant re-bleeding rate; whether the addition of thermal method improves the outcome is still unclear. Our previous experience showed that Argon Plasma Coagulation (APC) alone is not sufficient in stopping spurting haemorrhage, and potentially dangerous for large non bleeding visible vessels (NBVV). Our hypothesis was that combination of adrenaline injection (AI) and thermal therapy could be more efficient than thermal therapy alone for permanent haemostasis of active bleeding peptic ulcers, and particularly appropriate for NBVV treatment. From October 1998 to February 2000 we examined two hundred patients with upper gastrointestinal bleeding. Fifty-three patients with major peptic ulcer haemorrhages received combined injection therapy with adrenaline 1:10.000 and Argon plasma coagulation; there were 34 male and 19 female with a mean age of 63.2 +/- 1.2 years (range 22-93). The bleeding site was duodenal in 30 patients, gastric in 17 patients, anastomotic in 5 patients and esophageal in 1 patient. Endoscopic findings were the following: active bleeding in 23 patients (6 spurting, 17 oozing), non bleeding visible vessels in 12 patients and fresh adherent clots in 18 patients. Initial haemostasis was achieved in 52/53 patients (98.1%). Re-bleeding was observed in 5/52 cases (9.6%). Surgery was necessary in 3/53 patients (5.6%). Mortality was 7.5% (4 cases). No major complications resulted from this treatment. Primary adrenaline injection provided initial bleeding arrest, facilitating the following application of APC, because of a more precise definition of the active bleeding site. Rates of initial hemostasis were significantly higher with combined therapy (injection + APC) compared to APC treatment alone. We believe that Adrenaline and APC combined therapy is an effective and safe method for treatment of non-variceal gastrointestinal bleeding.

Merkel cell carcinoma is an unusual cutaneous malignancy with a propensity for spreading to regional lymph nodes, with recurrence at original site or/and in lymph node. Occurring most often on the head and neck of the elderly patients. Complete surgical resection is the mainstay of treatment of the primary tumor. A case is here described of an old patient with more than one local relapse and in regional lymph nodes too, complete surgical resected, actually in good state of health, treated with radiotherapy.

In a prospective study, the Authors present an analysis on the use of surgical adhesives in the wounds treatment. In sixteen months we have treated 157 patients exclusively with a surgical tissue adhesive 2-octylcianoacrylate to repair traumatic wounds and surgical ones. In the Emergency Department were treated 110 patients (70%) with 2-octylcianoacrylate for skin incisions, lacerations and the length of lesion. We have paid attention to prepare regular wound edges, irrigation and debridement when appropriate to reduce skin tension at the site of laceration. Forty-seven patients (30%) whit surgical skin incisions for thyroidectomy, appendicectomy, hernio-plastic and safenectomy were treated with 2-octyl-cianoacrylate. In both groups of patients, the surgical adhesive has made possible a simple and quick wounds repair as well as good aesthetic results. No relevant complications have been arisen. The writers recommend the surgical adhesive in Emergency Department to abridge waiting time and to avoid the psychological impact caused by local anaesthesia, suture and medications especially in the treatment of all wounds types in children.

In the last 30 years 1,484,576 patients with traumatic lesions of different kind of seriousness were observed and managed. By mean of retrospective investigation, the authors selected and statistically analysed a sample of 95 patients treated for accidental tracheobronchial foreign bodies inhalation: authors' aim was to punctually determinate--step by step--diagnosis and treatment procedure in a "time-saving" frame. Inhalation of foreign bodies is a very dangerous event, particularly in children. In authors' experience, in 60% of cases they were children under 3 years; in 25% of cases children under 10; in 10% patients from 10 to 60 and in 4.5% over 60. As regards the gender of the patients, the male/female ratio has been 2 to 1 in favour of male. Since 85% of the study population was represented by children under 10, its clear that male children in this range of age has a greater statistical risk for accidental tracheobronchial foreign bodies inhalation.

Deep vein thrombosis incidence is 1/1000 per year; it is associated with many risk factors which is considered as "thrombophilic states". Its pathogenesis is complex, caused by alterations of hemostasis system. Many studies have established the relation between cancer and subsequent venous thromboembolism, confirming the relationship of neoplastic cell interaction with coagulation system. Forty-seven patients admitted to the hospital from 1987 to 1996 with symptomatic clinically proved deep vein thrombosis were included in a retrospective study. Routine examination at the time of diagnosis of deep vein thrombosis revealed an occult cancer in 8 out of 47 patients; 9 out of 47 patients were admitted in hospital with vein thrombosis and known cancer. The aim of this study is to suggest the best, first treatment of vein thromboembolism in emergency to avoid the dangerous pulmonary embolism complication. The patients affected with deep vein thrombosis and cancer were elderly (over 70 years old, in mean); the neoplasia was of digestive system (8/17) in advanced metastatic stage there was cancer familiarity in 7 out of 47 patients. The high risk of pulmonary embolism associated to deep vein thrombosis suggests the importance of early starting the anticoagulant therapy and placing caval filter.

Somatostatin (SST) is used in the treatment of acute pancreatitis (AP) to inhibit pancreatic exocrine secretion, which represents one of the goals of medical treatment in this disease. Its therapeutic efficacy, however, is poor. One hypothesis, which has not yet been investigated, is that i.v. SST might be broken down by blood proteolytic enzymes. In order to evaluate the structural integrity and biological activity of infused SST, somatostatin-like immunoreactivity (SLI) and levels of pancreatic enzymes were monitored in the blood stream during the infusion of SST-14 (3,5 micrograms/kg/h for 48 h) in eight patients with severe acute pancreatitis. SLI was measured by both radioimmunoassay (RIA) and high-pressure liquid chromatography (HPLC). The results indicate that SLI levels increase promptly after the beginning of infusion, with a slower increase between 6 and 36 h, and a rapid increase again at 48 h. HPLC analysis shows a single peak of SLI with the same retention time as standard SST-14. Total amylase, lipase, and trypsinogen significantly decreased compared with pretreatment values (48, 63.1, and 77.4%, respectively) after 24 h of SST infusion, while a decrease in elastase 1 (62.6%) was observed later at 48 h. These results indicate that in severe AP, somatostatin recovered in plasma retains its biological activity: it inhibits pancreatic circulating enzymes, an action not influenced by breakdown of the peptide, as demonstrated by HPLC of the SLI measured in plasma.

Based on a survey of 47 cases of left colonic occlusive cancer operated on at the Emergency Surgery Department-University of Rome "La Sapienza", the authors concluded that in such condition, when the patient is not seriously ill, the Hartmann procedure is a valid alternative to the anastomosis-resection because: a) it solves intestinal obstruction in a short time with consequent improvement of general conditions; b) it allows to perform the second oncologically radical operation early with less risk of neoplastic spread. The latter procedure, therefore, is carried out under better conditions, relative to the stage of the disease and the status of the patient.

Personal experience in the treatment of acute pancreatitis with glucagon is reported. Results are highly satisfactory and encouraging in oedematous, interstitial and circumscribed steatonecrotic forms, disappointing where the disease has caused extensive damage to the gland.

Clinical outcome, bacteriological outcome, untoward microbiological effects, and clinical and laboratory adverse experiences mere evaluated, 98% of patients receiving imipenem/cilastatin therapy mere cured, with 96% showing eradication of infection, 95% of those on meropenem mere cured, with 98% showing eradication. These differences in clinical and bacteriological outcome between the 2 treatments were not statistically significant, Two patients receiving imipenem/cilastatin and 5 receiving meropenem had untoward microbiological effects. There mas a 0.7% frequency (1/139 patients) of possibly or probably drug-related clinical or laboratory adverse experiences with imipenem/cilastatin and a 2.7% frequency (4/148) with meropenem, The mean time to defervescence was significantly less for patients in the imipenem/cilastatin treatment group than for those receiving meropenem. This study shows that 1.5 g/day of imipenem/cilastatin is equivalent to 3.0 g/day meropenem in clinical and bacteriological outcome, as well as in incidence of side effects.
