[Sentinel lymph node for breast cancer: remove less to know more].

BACKGROUND: Our aim was to study the value of sentinel lymph node (SLN) biopsy in patients with breast cancer seen at a community hospital. METHODS: Consecutive cases receiving primary treatment for unicentric breast cancer less than 3 cm in diameter were prospectively studied from January 1999 to July 2000. All patients signed a detailed informed consent. The majority of patients (89%) underwent a combined technique of intradermal injection of 0.3-1.2 mCi of (99)Tc and 1-3 cc of Patent Blue at the biopsy site. Intraoperative localization was performed with a hand-held gamma probe. The first 15 patients underwent routine back-up lymphadenectomy. Thereafter, only patients with positive SLN, suspicious findings, or personal preference underwent formal axillary dissection. RESULTS: One hundred eight cases were included in the study with a median age of 61 years and a median diameter of the breast tumor of 1.5 cm. Success rate for identification of SLN was 94% (101/108 cases). A total of 917 additional lymph nodes were removed after SLN biopsy (median 6.5 lymph nodes/patient). Correlation between SLN and the final axillary status was 98%. In 20/36 patients (61%) with positive axillary status the sentinel lymph node was the only positive one. Ten patients had only microscopic foci of cancer found in the SLN. Sixty-seven patients (62%) could have avoided axillary dissection becouse the SLN was found, it was negative, and there were no other intraoperative suspicious findings. CONCLUSIONS: SLN biopsy is accurate and easily reproduced. Our data confirms that the majority of breast cancer patients may no longer need routine axillary lymphadenectomy.

A model of cost-outcome analysis for assistive technology.

During the CERTAIN study (research carried out in 1994-96 within the Technology Initiative for Disabled and Elderly (TIDE) programme of the European Union), a number of real life case studies of provision of assistive technology to disabled persons were investigated in order to assess the applicability of socio-economic principles, methods and techniques already available from Health Care Technology Assessment studies. A retrospective study on cost, effectiveness and utility resulting from the implementation of assistive technology was carried out over a sample of disabled persons who had adopted technical aids before the start of the project. The sample was selected in such a way to include different pathologies (steady or progressive), impairments, ages, technology and social environment. Each case was described by considering all clinical, technical and social aspects; a common structure for case reporting was developed and tested; attempts were carried out to apply and refine concept and tools derived from health technology assessment studies; on the grounds of such experience a decision support model was elaborated for the choice between different alternatives in order to maximize the client's quality of life while making efficient use of scarce resources. A computer implementation of such a model was also developed, along with a mathematical structure of cost analysis. Within a national research programme such findings were further exploited, leading to the development of a prototype cost-outcome instrument designed for use in clinical practice in the provision of assistive technology to individual cases.

Teleworking in connection with technical aids for disabled persons.

An experimental teleworking arrangement was established between Milan and Rome in order to evaluate the use of multimedia technology and remote working for improving the service provided by an information and advice centre for the disabled. This activity requires a highly interdisciplinary approach and both clinical and technical expertise. The hypothesis was that offering the lone expert in Rome the possibility of teleconsulting with colleagues in Milan (where the whole range of expertise was available) would provide a comprehensive service for disabled clients asking for advice on technical aids in Rome. The results of an experiment demonstrated the feasibility of such teleworking and allowed a teleconsulting method to be defined that fits the specific needs of the technical-aid information service and improves quality.

[Clamping the suprahepatic inferior vena cava in emergency surgery. Technical note].

In major hepatic surgery the temporary exclusion of the vena cava may be achieved using a variety of more or less complex procedures. Alternatively, for use above all in emergency surgery, the paper illustrates a method of clamping the suprahepatic inferior vena cava using a left lateral route, which is quick to carry out and undoubtedly efficient.

[Total parenteral nutrition in surgery].

Following a number of general remarks regarding the metabolic physiopathology of the surgical patient, the indications and biochemical premises for total parenteral nutrition are examined. Stress is also labor, on problems of administration routes and modalities and on the chemico-clinical controls needed to weigh up the technique. Finally, the results of personal experience in the treatment of 16 patients whose prevalent pathology consist of necrotico-haemorrhagic A.P. and its sequelae are reported. The usefulness of the technique is confirmed because it offers interesting results in difficult and often dramatic surgical situations.

[The Hartmann procedure in colorectal emergencies. Report of 76 cases].

The Hartmann procedure has, in emergency colo-rectal surgery, many implications. The decision is based on clinical, radiological, instrumental and pathological findings. The authors report the results of 76 Hartmann's procedures performed between 1986 and 1995 and compare their results with those found in the current medical literature on the topic. In particular, they draw attention to an increased use of this procedures in colo-rectal emergencies; the morbility and mortality rates confirm the severity of the clinical cases that can be treated with this operation. To improve results the authors propose a therapeutic plan that uses a score for stratification of the risk (MPI, APA-CHE II, SSI, Hinchey); so the surgeon can choose the best surgical operation. Finally, the authors underline the importance of the principles of oncology surgery in colo-rectal cancer.

[Colorectal reconversion after Hartmann procedure. Apropos of 26 cases].

The authors report the RCR results executed on 26 patients submitted to Hartmann operation for colo-rectal emergency at the Surgical Department of S. Giovanni Hospital during the period 1986-1995. The reconversion index (46.4%), the morbidity (42.3%) and the operation mortality (3.8%) agree with those reported in the writings. Therefore, the tactical, technical and prognostic aspect related to RCR are examined, a heavy operation fully justified by the patient quality of life expectations.
