[Mixed carcinoid-adenocarcinoma tumor of the appendix: a case report and diagnostic and therapeutic considerations].

The layout of the work has stayed motivated from the recent observation of mixed carcinoid, located to the appendix and wide to the peritoneal cable, joint to our observation in an elderly patient with aspecific demonstration clinical-symptomatologic. The study of the endocrine tumors is in continuous evolution also if, to the actual state, there is a better comprehension of this neoplasm, variegated and complex and, under some appearances, still not known well. Jejunoileal carcinoid tumors differ, under many appearances, from those occurring in other sites of the gut. They have relatively high rate of transmural invasion and aggressive clinical behavior, contrasted by a scarce objectivity; the demonstration of symptoms generally implicates the presence of an illness in advanced stage. Also pharmacological therapy made important progress, with the possibility of administer composed able to interfere with the development and the neoplastic growth.

[Ambulatory surgery: preoperative assessment].

Over the past 20 years public health expenditure has progressively increased for various reasons. With the aim of reducing public health expenditure and hospital stays, alternative models of public health care have been more widely adopted over the past two decades: Day Hospital, day surgery and ambulatory surgery. What is meant by ambulatory surgery is the clinical, organisational and administrative possibility of performing surgical operations and/or invasive and semi-invasive diagnostic procedures without hospitalisation of patients, in doctors' surgeries, outpatient departments or protected outpatient facilities. For both the patients and the centres providing the service to be able to exploit all the advantages stemming from this kind of health care provision, careful patient selection is mandatory, including assessment of the impact of any potential concomitant pathologies. Starting from their own personal experience and existing reports in the international literature, the authors analyse the impact that concomitant pathologies may have on patient selection for ambulatory surgery. The authors conclude that thorough preoperative evaluation of all the possible variables involved is the only way of ensuring the success of ambulatory surgery.

Virtual endoscopy: already a feasible proposition or a future prospect in diagnostics? A review of the literature.

The aim of this article was to carry out a retrospective analysis of the feasibility of using virtual endoscopy in the field of gastrointestinal diseases. After a retrospective review of the international literature the authors analyse the most controversial aspects of virtual endoscopy such as its effective diagnostic reliability and potential clinical employment with specific reference to diagnosing colon diseases. The international literature shows that virtual endoscopy is currently poorly sensitivity in detecting lesions measuring less than 10 mm in diameter and that the radiologist's experience can negatively condition the trustworthiness of this procedure. Virtual endoscopy is likely to be the future gold standard in the field of diagnostic imaging. Furthermore, it eliminates all the compliance-related problems and any risk of iatrogenic lesions such as perforations and bleedings which are typical of traditional endoscopy. Its current sensitivity, however, is poor and it is unable to detect lesions smaller than 10 mm. Its reliability therefore needs to be improved.

Intestinal occlusion secondary to Morgagni-Larrey's herniation in an adult. Case report and analysis of the literature.

Morgagni-Larrey's hernias are congenital diaphragmatic hernias, rarely observed and generally identified accidentally due to the lack of symptoms. The authors report a case of intestinal occlusion secondary to Morgagni-Larrey herniation in an adult recently observed and underline the aetiopathogenic aspects, the diagnostic tools and the clinical pattern. They suggest to consider surgical repair as a choice of treatment, also for asymptomatic patients.

[Subrenal coarctation of the aorta. Presentation of a clinical case].

Coarctation of abdominal aorta constitutes a rare group of vascular abnormalities, including segmental stenoses and extended hypoplasia below the restriction. Usually hypertension is the only clinical evidence. The natural history of the surgically untreated disease foresees a decline of life expectancy; while surgical operation permit an almost complete "restitutio ad integrum". The Authors report a case of coarctation of the abdominal aorta come to their observation whose particularly was determined by the absence of high blood pressure, the aortic stenoses being located under the renal arteries.

[Deep venous thrombosis and surgery. Assessment of the main risk factors].

Deep venous thrombosis is a quite frequent pathology with a high degree of morbidity and death-rate. Two are the main problems of this disease: the risk of pulmonary embolism and outcome of a post-thrombotic syndrome, leading patients to infirmity. The patients max exposed to the risk of deep venous thrombosis are the surgical ones: the authors, with a retrospective study on 480 surgical patients, examine the risk factors mostly related with the onset of deep venous thrombosis. At the end they refer about connection between the risk factors studied and the clinical display of in surgical patients.

[Thoracic lymphadenectomy in video-assisted mini-invasive thoracic surgery. First experience].

The Authors report their experience in the thoracoscopic surgical treatment of neurovascular abnormalities of the upper extremities. The experience acquired in the last two years with mini-invasive video-assisted thoracic surgery of the pleura and lung forced the Authors to perform thoracic sympathectomy following the same approach. In this way 4 thoracic sympathectomies were performed in 3 patients. Two of them presented Raynaud's phenomenon, and one was affected by bilateral idiophatic upper limb hyperhidrosis. The operation is performed thanks to 3 12mm Thoracoports that allow the introduction of the telescope and operative instruments. It is easy to recognize and remove the sympathetic gangliar chain from T2 to T3. The short operative time required, the absence of mortality and morbidity, the regression of the symptomatology, the rapid return to work authorize to consider endoscopic transthoracic sympathectomy the gold standard in the treatment of neurovascular abnormalities of the upper extremities.

[Duplex scanner diagnosis of complete extracranial carotid artery obstruction: possibilities and limitations].

The authors enhance the current importance of the hemodynamic evaluation of the vascular carotid territory by means of Doppler-CV although the great development of the "real time" ultra sonographic imaging. Combined US/Doppler-CV technique is really useful in differential diagnosis of the severe obstructive disease of extracranial carotid arteries. The authors report the possibilities of pitfalls in diagnosis due to the limitation of devices employed or to the frequent anatomical variability featured by examination of severe obstruction of vascular carotid territory.

[Carcinoid of the pancreas. 2 case reports].

Two cases of carcinoid tumors are reported: the most important characteristic of these neoplasms are that they are uncommon and are accidentally and difficulty diagnosed. Surgery, when possible, is the treatment of choice for the carcinoid tumors of the pancreas, but in unresectable tumors chemotherapy, radiotherapy and interferon are used.

[Morphologic anomalies of the extracranial internal carotid artery. Our experience].

Cerebro-vascular insufficiency may be caused by morphologic anomalies of the extracranial internal carotid artery (10-15% of symptomatic patients). These alterations are characterized by anomalous elongation which conditions particular attitudes of the carotid: tortuosity, coiling, kinking. In the first case the artery assumes an "S" or "C" shape; in the second the elongation is more emphasized and the artery develops one or more loops; kinking, the most frequent morphologic anomaly, is a sharp angulation of the first part of the internal carotid artery. The etiology of these anomalies seems to be related to congenital causes, that may be unmasked by arterial growing old process. Surgical correction, indicated for symptomatic patients or patients with important hemodynamic alteration, requires rectilinearisation of the internal carotid artery associated with TEA eversion of the same.

[Cutaneous mechanical staplers. Our experience].

This paper reports the results of a trial, comparing the use of disposable skin staplers with conventional nylon or silk sutures in skin closure. This study began in 1986; 7274 patients undergoing elective and emergency operations were controlled during the postoperative period, 3 and 6 months after surgery. It was shown that skin clips instead of sutures decrease the operative time, produce wound healing with a good cosmetic results, and above all a significant lowering of the wound infection rate.

[Adenomyomatosis of the gallbladder. Our experience].

Adenomyomatosis is a rare affection of the gallbladder and it's infrequently reported in the Literature. Having observed eighteen cases of adenomyomatosis of the gallbladder in the last five years and considering the difficulties in making an early diagnosis of gallbladder cancer, the authors suggest the importance of cholecystectomy in this pathology.

Reversal of Hartmann's procedure. Our experience.

Hartmann's procedure has progressively changed its indications in the last years; nowadays they are reduced by the increasing of anesthesiology and the introduction of stapler devices. The introduction of staplers makes reconstructive operation easier and it contributes to a sensible increasing of reversal percentage after Hartmann's procedure. Video-assisted techniques make Hartmann's procedure possible for older patients with high-risk of post-operative general complications. The authors describe the results obtained with traditional and video-assisted reversal Hartmann's procedure, comparing with data from Literature.

[Laparoscopy in iatrogenic lesions of the colon during operative endoscopy].

Colonscopy is a standard diagnostic and therapeutic procedure that has its own morbidity. Colonic perforation is the dangerous complication of this procedure. Successful management of perforation by conservative or surgical treatment remains controversial. We report two cases, recently observed, of patients with colonic perforation occurring during therapeutic colonscopy treated with minimally invasive technique.
