[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.

[A new technique in positioning of Kehr's tube in laparoscopy].
The enlargement of the indications in the use of the laparoscopic technique puts the surgeon in front of the need to project new techniques and to improve new instruments daily. On one hand, the technique and instruments used to perform a video-laparoscopic cholecystectomy are codified. However, there is still a lot of work to do for the laparoscopic treatment of the common bile duct stones. The aim of the present scientific contribution is the exposition of an original methodology for the positioning of the T-tube in laparoscopy which would be a difficult manoeuvre otherwise.

[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.

[Mediastinoscopy in a general surgery department. The evaluation of 186 cases].
A series of 186 cases of mediastinoscopy performed in a department of general surgery is reported. The main indications for this procedure are: histological diagnosis of mediastinal masses, definition of bronchopulmonary neoplasms and thoracic esophagus ones with indication for surgery. The results obtained are: sensibility 90.3%, complications 3.7%, mortality rate 0%. The authors believe in the great utility of mediastinoscopy in case of unknown histotype of primary neoplasms and CT N2? involvement.

[Atraumatic skin closure with Fasterzip].
The Authors report their experience of skin closure using a new device, a surgical "zipper", without applying any sort of sutures. The application of this device, the functional and aesthetic advantages and the results obtained are described.

[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.

[Treatment of spontaneous pneumothorax with video-assisted mini-invasive thoracic surgery. First long-term results].
The spontaneous pneumothorax (pnx. s.) is a type of pathology with a high per cent of relapse so its aetiological treatment can't be done only with a pleural drainage. With the resection of the bubble (that is the cause of it) instead, the problem will be resolved without possibilities of relapses. In the past, this was possible only with a thoracotomy, now with the new techniques of video-thoracoscopy, the therapeutical approach to this pathology has been revolutionized. In fact, this methodology resolves definitively the pulmonary lesion, can avoid the relapses, can guarantee a short stay in hospital and a very good restarting of the working and social activity.

[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.

[The indications for prophylactic colectomy in diverticular disease].
Still controversial is the role of surgery in symptomatic colon diverticular disease, outside the major complications. In such circumstances the surgeon has to comfort himself with diagnostic and then with operative choices, and also the preventive colectomy has to be considered. To make a correct decision very important is the global evaluation of the patient, for age, sex life habits, other existing pathologies, general condition. Also unsolved doubt for a neoplastic evolution has its worth.

"Carcinoid tumorlets". Case report and review of the literature.
It is reported a case of "carcinoid tumorlets" of the lung, in a 63-year-old woman, who underwent surgery for a breast cancer. These lesions are histologically similar with carcinoid, but different for clinical evolution. They are benign lesions generally without metastasis. The authors point out the importance of histological, clinical and diagnostical aspects, and the follow-up of patients in order to have evidence of the eventual malignant evolution.
