RESUMEN
INTRODUCTION: Aim of our study was to compare the results of the laparoscopic technique to those obtained by traditional open approach in patients with colon cancer. The advantages, disadvantages, and the contraindications (real and presumptive) of this mini-invasive approach are described, by comparing the data obtained from the international literature with our clinical experience. PATIENTS AND METHODS: From February 2000 to May 2006, we performed 73 laparoscopic colectomies for cancer in the Operative Unit of General and Laparoscopic Surgery, Department of Surgical Sciences of the University of Chieti, Italy. The data of these patients were compared with the data obtained from 141 other patients who underwent open procedure for the same pathology in the same period and in the same Unit. Factors such as obesity, previous major abdominal surgery, T4 cancers, perforation and obstruction of the colon, tumor located in the transverse colon or in the left flexure of the colon were considered contraindications to laparoscopic approach. RESULTS: The length of surgical specimens and the number of lymph nodes removed did not show significant differences in the two groups. Two patients in the open procedure group died in the postoperative period. No postoperative death was noted in the group of patients operated by laparoscopic method. Postoperative complications requiring re-operation were observed in 9 patients in the open group and in 3 patients of laparoscopic group. Postoperative complications not requiring re-operation were observed in 16 patients in the open group and in 4 patients in laparoscopic group. Hospital stay was shorter for laparoscopic right or left colectomy compared to corresponding open procedures. At the follow-up (a mean 30 months), the overall survival was 78% for open colectomies and 82.1% for laparoscopic colectomies. Disease-free survival, excluding patients with stage IV tumor and patients died in the postoperative period, was 77.6% for open colectomies and 82.5% for laparoscopic colectomies. In the group of laparoscopic patients, we observed 1 case of port-site recurrence. CONCLUSIONS: Our clinical experience, even if limited by the number of patients and by the duration of follow-up period, contributes in confirming the reliability of laparoscopic procedures in the treatment of tumours of the colon and the safety of oncological results.

Of unknown etiology, mainly located on the upper limbs, the nodular fasciitis nowadays is considered as a reactive inflammatory lesion more than a neoplastic one. With very few symptoms, it can be diagnosed through histology and the extent of the excision is related to the report of the pathological examination.

We describe a case in which segmental resection of the third and fourth portion of the duodenum was performed for a very rare duodenal gastrointestinal tumor (GIST). A 58-year old man presented with melena. Capsule endoscopy revealed a pathological bleeding of the duodenum and oral contrast-CT enema confirmed a lesion of the duodenum inferior knee, measuring 3.5 cm in diameter. Such an image suggested a duodenal leiomyoma. Segmental resection of the third and fourth portion of the duodenum after intestinal derotation (Valdoni-Strong's procedure) was carried out and there were no post-operative complications. Pancreas sparing duodenal resection is at the present time indicated only in selected cases. The duodenal resection associated with bowel and right colon derotation has proved to be a safe and adequate procedure and could be preferred to other procedures.

The Authors review the international literature about the frequency of vascular involvement (inferior vena cava and aorta) in the lymph node lumbo-aortic metastases of the testicular neoplasm. They report a case of a patient with an aortic involvement from lymph node metastases of a mixed (seminoma and germ cell) cancer of the left testis. They performed en bloc resection of the bulky metastases including the aorta involved. The literature data as well as the outcome of the operated case show a moderate survival also in patients with advanced disease.

From a review of a series of 12 cases of whom 52 operated and of the literature, the Authors discuss about aetiology, pathogenesis and diagnosis of severe colitis. Clinical and laboratory findings, CT and plain films of the abdomen and at last colonoscopy should be evaluated very carefully for certainty diagnosis of a severe acute colitis or toxic megacolon. They suggest a multidisciplinary approach as fundamental for medical management, for indications and correct timing of surgical procedures and to decrease postoperative morbility and mortality. Total colectomy with ileostomy is recommended in emergency surgical treatment of this colonic acute diseases, whereas for urgency operation, performed not later than 48-72 hour of adequate medical treatment, colectomy is suggested with ileorectal or ileoanal anastomosis and ileostomy.

The PJ, introduced by Rosen in the 1980, is a benign and localized mammary lesion in female under 30 years old. The most important clinical and histological features are: Diagnosis in juvenile age. A mass clinically localized. A nodule with histologic features of cyst, benign hyperplasia of ductal epithelium and galactophorus ducts dilatation (Swiss cheese disease). There is a correlation between patients with PJ and breast cancer there is an increment of breast cancer in familirs of patients with PJ. There is an increment of the risk to develop a K in situ in patients with PJ and apocrine metaplasia and/or adenomatosis and/or atypical mastoplasia. We describe the diffuse PJ in a girl of 23 years old from the 1996 to 2002.

Fourier transform Raman (FT Raman) and IR (FTIR) and (1)H-NMR spectroscopies coupled with differential scanning calorimetry (DSC) were applied to the characterization of root exudates from two cultivars of gladiolus (Spic Span and White Prosperity) with different degrees of resistance and susceptibility to Fusarium oxysporum gladioli, the main pathogen of gladiolus. This work was aimed at correlating the composition of root exudates with the varietal resistance to the pathogen. Spectroscopic analysis showed that White Prosperity root exudate differs from Spic Span root exudate by a higher relative amount of the aromatic-phenolic and sugarlike components and a lower relative amount of carbonylic and aliphatic compounds. DSC analysis confirmed the spectroscopic results and showed that White Prosperity root exudate is characterized by an aromatic component that is present in a higher amount than in the Spic Span root exudate. The results are discussed in relation to the spore germination tests showing that White Prosperity, which is characterized by a remarkable resistance toward F. oxysporum gladioli, exudes substances having a negative influence on microconidial germination of the pathogen; root exudates from Spic Span, one of the most susceptible cultivars to F. oxysporum gladioli, proved to have no effect. White Prosperity's ability to inhibit conidial germination of F. oxysporum gladioli can be mainly related to the presence of a higher relative amount of aromatic-phenolic compounds.

The authors report 3 cases of benign duodenal tumors and one case of duodenal cancer. In two cases the benign tumors were adenomatous polyps, in one case with signs of dysplasia. One case of benign tumor was a lipoma. All the three benign tumors were removed through a duodenotomy, in one case associated with a sphincteroplasty. The case of duodenal cancer, arisen in a patient operated since 24 years with a gastric resection, was treated with a Whipple technique but for the very old age and the bad health conditions, the patient died in 11th post-operative day for myocardium infarct.

The authors report cases of pheocromocytomas operated in the period 1991-1997. 16 of these patients presented a monolateral pheocromocytoma, 1 a bilateral. A patient had a malignant evolution, one patient presented an extrasurrenal para-aortic localization. All the patients were operated by a middle longitudinal laparotomy. There was no mortality, neither significant morbility. In all the patients, who presented pre-operatory arterial hypertension, there was a regression of the symptomatology.

Medullary thyroid carcinoma represents 4-8% of thyroid malignancies; regional nodal involvement is commonly found, even at the time of first surgical approach. In these patients after surgical resection, other therapeutic choices are really limited. The Authors evaluated their experience in the period 1981-1994, concerning 14 patients, 9 females and 5 males, all affected with sporadic MTC. Diagnosis was preoperative in 10 patients and intraoperative in 4; as for the staging: in 8 patients the tumor resulted confined to the thyroid, while in the remaining 6 patients it was extra-thyroidal. In 5 patients a total thyroidectomy with regional lymphadenectomy was performed, with in 6 patients a total thyroidectomy with cervico-mediastinic total lymphadenectomy was achieved. Survival was evaluated with a short, follow-up (3 months) and calculated using the K-Mayer method. Average survival was: 5 years in patients undergoing only total thyroidectomy; 3 years and 1 month in patients undergoing total thyroidectomy and lymphadenectomy; 6 months in patients undergoing no treatment at all. Among the factors negatively affecting patients survival, the Authors pointed out: metastasis occurrence; incomplete resection and mediastinal metastasis. In conclusion surgical resection (total thyroidectomy) associated with radical lymphadenectomy resulted to be a good approach. However, prognostic factors require further investigation.

A questionnaire concerning the prophylaxis of venous thromboembolism was filled in by 326 surgical departments in Italy. In 58% the prophylaxis was routinely used and in 29% more than one method was used. The most used method of prevention was subcutaneous heparin followed by elastic compression. In 51% of the centers the prophylaxis was used only in high risk patients and in 22% it was not used at all. The most relevant risk factors in the development of thrombosis were considered age, tumors and obesity. Finally in a questionnaire sent to 350 vascular laboratories it was found that--according to the operators--76% of all documented thromboses were possibly consequent to surgical procedures (in 86% no prophylaxis had been used).

A personal experience about 135 pz. with non-toxic goitre treated by mono o bilateral thyroidectomy and followed during 5 years (2-8) to evaluate the incidence of recurrences is reported. The recurrences were 10.5%, especially after monolateral thyroidectomy (9 pz.). Therefore the authors stress the importance of a more accurate surgical indication, a wider resection of the gland and a careful follow-up to undertake opotherapy when hypofunction appears.

A case series of 5 male patients afflicted with breast carcinoma is reported. The Authors describe symptomatology, diagnostic iter, principles of surgical treatment and results. Underlined is the wider surgical demolition in male breast cancer in comparison with females, even if natural history and biological conduct are comparable. This is because in male breast carcinoma the local and remote infiltration is more rapid than female for the less development of breast gland. Finally, indications for radiochemotherapy are comparable to female breast cancer.

A new system to study capillary permeability, the VSC (vacuum suction chamber) device has been developed to evaluate the variations of capillary permeability in postphlebitic limbs. The VSC device produces by negative pressure [obtained in a plastic chamber applied to the skin at the perimalleolar region] a wheal which disappears in normals in less than one hour. In twelve patients with moderate [superficial] venous hypertension and in twelve patients with postphlebitic limbs the time of disappearance of the wheals was significantly longer in comparison with ten normal limbs. There was also a significantly increased time of disappearance of the wheals in postphlebitic legs in comparison with those with superficial incompetence. The validation of the VSC technique with venous occlusion plethysmography (VOP) showed that the increase of time of disappearance of the wheals is well correlated with the increase of capillary permeability demonstrated by VOP. After 2 weeks treatment with Venoruton (at the dosage of 1000 mg t.i.d.) the time of disappearance of the wheal was significantly reduced in both groups of patients (while it was unchanged in normals). Laser-Doppler parameters used together with the VSC device to evaluate the microcirculatory changes associated with an altered capillary permeability also showed a significant improvement of the laser-Doppler parameters after treatment. In conclusion there is evidence by the VSC device that capillary permeability [which is abnormally increased] in chronic venous hypertension is improved [decreased] after treatment for two weeks with Venoruton. This study demonstrated also the efficacy of the VSC device to study capillary permeability and the effects of drugs active on capillary permeability.

An extensive review of epidemiology, etiology, age, genetic factors, race, alimentary habits and hormonal patterns have been analysed in studies concerning patients with breast cancer. The role of other factors (the age of menopause, the geographic distribution, the action of reserpine and many possible causes) are also discussed. The evidences observed in many studies performed in the last years in different countries are compared but definitive data cannot be reached. The material reported in these studies is not homogeneous and this review can only indicate the problems still present in this field and the subjects we need to investigate in the next years.
