[Surgical treatment in day surgery of uncertain breast lesions].

AIM: New models of care are proposed to reduce the costs of traditional hospitalization and to improve the utilization of resources in surgery. Day surgery is widely employed in breast surgery. In this study we report the conversion rate and causes in ordinary hospitalization and we identify some contraindications related to breast surgery in day surgery. METHODS: A cohort study was performed on 306 patients operated on between July 1999 and December 2001 for breast lesions with uncertain interpretation at the clinical and/or instrumental examination. Those patients who lived at a distance of less than 50 km from the hospital, had a telephone, a suitable house, direct family support and, if necessary, could benefit from home health care in addition to hospitalization, were considered as eligible to day surgery. The kind of anesthesia and hospital admission were established after clinical, psycho-emotional, and socio-familiar evaluation of the patients by the surgeon and the anesthetist. RESULTS: A total of 250 excisional biopsies and 56 biopsies with a Mammotome were performed. Surgery was performed under local anesthesia in 278 patients and general anesthesia in 28 subjects. Observation exceeding 24 hours was only necessary in 10 patients reporting hypotension syndrome and anxiety. The conversion rate in ordinary hospitalization was 0.3%. Postoperative morbidity was 1%. CONCLUSION: Day surgery is an effective model of care in breast surgery for diagnostic and therapeutic purposes without axillary dissection. A good selection of patients, perfect interdisciplinary collaboration, and an efficient structural organization are necessary to control the complication and conversion rates of traditional hospitalization.

[Mature cystic teratoma of the ovary with differentiated and secretive gastric mucosa].

Large teratomas with gastric mucosa are rare. We report a case of mature cystic teratoma in an ovary of a young woman. Tumor growth was large and rapid enough to displace abdominal organs. The cyst was aspirated (removing 101 of mucinoid liquid) and excised by medial hypogastric laparotomy. The histological examination revealed differentiated gastric fundal mucosa with no other tissue involvement.

[Central venous catheterization: complications of different placements].

STUDY AIM: The aim of this prospective multicentric non-randomised trial was to report the complications of the central venous catheter insertion with different techniques and to assess the advantages of the low lateral approach to the internal jugular vein, according to the technique originally described by Jernigan et al, with our own modifications. PATIENTS AND METHOD: From January 1993 to August 1997, 2,290 CVC (2,286 by percutaneous puncture and 4 by surgical approach) were placed. The following complications were analysed prospectively: pneumothorax, accidental arterial puncture, more than two punctures of the same vein, necessity to shift to another venous approach, complete failure, malposition of catheter. RESULTS: The veins the most frequently used were internal jugular vein (48.7%), femoral vein (27%) and subclavian vein (24.2%). Internal jugular vein was punctured especially by low lateral approach (75%) and subclavian vein by infraclavicular approach (92%). With these two placements, the rate of pneumothorax was 0% and 3.1% respectively (p < 0.001), the rate of accidental arterial puncture was 1% and 2.7% respectively (p < 0.03) and the rate of more than two consecutive punctures was 3.1% and 6.3% respectively (p < 0.008). CONCLUSION: On our experience, we advocate the low lateral approach to the internal jugular vein as first choice technique for venipuncture in both adults and children for both short and long-term central venous approach, because it is associated to high rate of outcome and to low rate of complications in comparison with other techniques.

[Rectal prolapse].

Rectal prolapse and rectal intussuception correspond to two stages of the same disease. Rectal prolapse is unusual but requires surgical treatment. Abdominal rectopexy is the most effective procedure but increases the risk of postoperative constipation. This risk decreases when the lateral sides are not touched during rectal dissection. The Delorme procedure is associated with a higher rate of recurrence and must be reserved for patients presenting a high risk of postoperative complications. Rectal intussuception is more frequent and is pathological only when arising in the anal sphincter. Rectal intussuception may lead to solitary rectal ulcer and has in this case to be treated by rectopexy. Rectal intussuception involvement in terminal constipation is not yet proved. Internal mucosectomy seems to be the best treatment for terminal constipation.

Radioimmunoguided surgery in colorectal cancer: a 6-year experience with four different technical solutions.

Intraoperative radioimmunodetection is a new staging technique for epithelial neoplasms. After intravenous injection, a radioimmunoconjugate compound (monoclonal antibody and isotope) attaches itself to the antigens expressed on the surface of neoplastic cells, causing them to emit gamma rays. Radioactivity is detected at the presurgical stage by immunoscintigraphy and intraoperatively with a gamma-detecting probe (GDP). In our experience, intraoperative tumor-to-normal-tissue (T/NT) GDP ratio counts > or =3:1 were considered positive radioimmunoguided surgery (RIGS) findings. We studied 52 colorectal cancer patients, 48 with primary lesions and 7 with relapses. Positive RIGS findings were obtained in 33 patients whose lymph node assessments were characterised by eight false positive identifications. In 10 patients, RIGS data yielded a more accurate staging of the disease. Unreliable RIGS findings were recorded in 15 patients: four injected with monoclonal antibody (MAb) B72.3 labeled with Iodine-125; five with MAb anti-carcinoembryonic antigen (CEA) labeled with 99mTechnetium (Tc); two with MAb B72.3 labeled with Indium-111; and three with MAb B72.3 labeled with Iodine-131 plus interferon-beta. In analysis, our experience did not permit definitive evaluation of the method's diagnostic and staging accuracy.

[Pleural plaque fibrosis: a clinical case].

A recent case of pleural plaques fibrosis in a worker exposed since 20 years to asbestos induced us to report our experience. A 52-year-old man was seen because of chest multiple opaques of soft tissue density without any symptoms. The CT-scan of thorax with i.v. contrast showed multiple lesions of diameter 0.5-4 cm on the posterolateral pleura bilaterally. FNAB of one lesion CT guided was not diagnostic. The pleural biopsy obtained at surgical exploration showed hyaline tissue, avascular, almost acellular, with calcifications and inflammation of low grade. The pleural plaques are generally multifocal and bilateral. They usually affect the parietal pleura. The connection between asbestos and plaques is firmly established. The pathogenesis is not well known. The pleural plaques fibrosis is a benign disease and a very common manifestation of asbestos exposure; it is not related to mesothelioma and it does not need any treatment. Because of the lack of symptoms it must be searched for in high risk subjects.

[The integrated radiosurgical treatment of rectal cancer].

The value of radio-surgical protocols in the treatment of advanced rectal cancer has been studied retrospectively. 21 patients operated between 1986 and 1990 fulfilling some criteria were considered for this study. They were 9 men and 12 women with rectal cancer Duke's stage B2-C; 16 were treated with preoperative radiotherapy (30-35 Gy), 5 were treated with postoperative radiotherapy (40-60 Gy). The operative procedures were 12 anterior resections and 9 Miles operations. The 5 years results were: a) cancer free survival 52%; 2 patients alive with relapse; 2 patients with non cancer related death (DIC, radiation enteritis); d) cancer related deaths 28%; e) local recurrence was observed (3 pts) only in association with metastatic disease; f) no isolated local recurrence was observed. Preoperative radiotherapy with 30-35 Gy is judged the preferred protocol for decreasing the rate of isolated local recurrence and for increasing the survival rate. Omental flap transposition plays an important role in the radio-surgical treatment of advanced rectal cancer.

[Blood coagulation changes in patients with post-splenectomy persistent thrombocytosis].

To clarify the possible role of persistent thrombocytosis after splenectomy as being a predisposing factor causing thromboembolism. Blood coagulation profiles were studied in 35 patients (20 M and 15 F, mean age 42 +/- 17.5) suffering from thrombocytosis (> 500,000/dl) who underwent splenectomy for non-malignant and non-traumatic diseases. Seventy healthy subjects acted as a control group. Tests were performed 6 months after the operation and for both groups (patients and controls) blood samples were collected for: platelets, fibrinogen, PT, APTT, AT III, plasminogen, F1 + 2, t-PA and DNA analysis for F V, F II and MTHFR. After one year all subjects were controlled for thrombocytosis, genomic abnormalities and venous thrombosis. All the analyses were performed according to the Statistical Package for Social Science. The significance of the differences in means was evaluated by non-parametric tests, differences with a P value < 0.05 being considered significant. Increased plasma levels of fibrinogen, D-dimer, F1 + 2 and PAI-1 were found in the patients compared with the control group. TPA was significantly lower in the patients than in the controls. At the one year follow-up, two patients with genetic polymorphism had suffered deep venous thrombosis. Our findings indicate that splenectomy contributes to abnormal platelet aggregation and endothelial cell activation with hypercoagulability.

Sentinel node biopsy for breast cancer: a critical analysis.

The concept of sentinel node biopsy, initially introduced for melanoma, has also been used for breast cancer since the 90's, in that, with the increasingly, widespread use of mammographic screening and of other minimally invasive diagnostic procedures, smaller and smaller cancers are now being diagnosed. For these cancers axillary dissection often constitutes overtreatment. For cancers at an initial stage with a low risk of axillary metastases investigation of sentinel lymph nodes enables us the surgeon to assess the axillary lymph-node status and avoid axillary dissection which is responsible for a certain amount of morbidity. Sentinel nodes can be sought using colorimetric or radioisotope methods. To date there is no common consensus of opinion as to which is the better procedure and the respective indications. Both methods allow detection of sentinel nodes in roughly 90% of cases and the combination of the two yields 100% detection rates. It is widely accepted that sentinel node biopsy should be reserved for unifocal tumours which have not been treated previously and which measure less than 15 mm in diameter. The advantages of the procedure are substantial provided it is performed correctly by surgeons properly trained in its use. The learning curve is relatively brief and is based on no more than 30-40 cases.

[Breast-conserving surgery in breast cancer].

Breast-conserving surgery is the treatment of choice for the breast cancer T < 3 cm. The local recurrence is a problem of diagnosis and consequent treatment. We enrolled, from 1987 to 2004, 1504 breast cancer. In 803 (53.4%) tumor with T < 3 cm we performed conserving surgery. The sentinel lymph node (SN) technique induce to limit the axillary dissection in patients T1a-b to the SN only if non metastatic and located to the first level, the dissection of the 1st level of the axilla in patients T1c-T2 < 3 cm and SN negative, complete axillary dissection in patients with metastatic SN or located to the 2nd level. Our percentage of local recurrence in the follow-up was 3.5% at 5 years and 6% at 10 years.

[Ductal carcinoma in situ of the breast].

The Authors report their experience about 127 ductal carcinoma in situ (DCIS) of the breast. Guidelines for surgical treatment are: radiological or clinical diagnosis, tumor's extension, histological classification, grading and margin status. At the present the Authors prefer breast conserving surgery with tumor margin's study. They report their experience in the last seven years about sentinel node biopsy. Radiotherapy and endocrine therapy are indicated for selected patients; local recurrence after DCIS therapy is 8,1% on a 6,1 years follow-up.
