[Technic of continuous axillary plexus block].

A technique of continuous axillary brachial plexus block, using an epidural Tuohy needle and an epidural catheter, is described. Studies were carried out in ten patients using this technique with bupivacaine as a local anesthetic drug. The catheter remained indwelling during a mean period of five days. Good analgesia was obtained in nine out of the ten patients. Thus this technique allows pain-free postoperative period in hand surgery.

Breast cancer takes up 99mTc bombesin. A preliminary report.

BACKGROUND: Several tumors including lung, prostate, ovarian, colon, and exocrine pancreatic cancer show receptors for the amphibian neurotransmitter and growth factor bombesin (BN) and its mammalian counterparts gastrin-releasing peptide and neuromedin B. Also breast cancer has been reported to show such receptors: the presence of BN receptors in primary breast cancer has been demonstrated on cultured cells and by autoradiography on breast tissue samples. Authors who have studied BN receptors in breast cancer do not agree on their frequency in primary cancer, but indicate that 100% of metastatic breast cancers show such receptors. METHODS: We examined three primary breast cancer patients with 99mTc BN and 99mTc sestamibi one week before surgery. One of them showed axillary node invasion. The same acquisition technique was used for breast and chest imaging with both radiopharmaceuticals, whereas total body images were acquired only with 99mTc BN. Also the administered radioactivity was different: 20 mCi of 99mTc sestamibi and 5-8 mCi of 99mTc BN. Dynamic images were acquired for 20 mins after iv injection with the patient in ventral decubitus and the gamma camera positioned in a lateral view, as is generally done in Khakhali's prone scintimammography. Anterior chest images were acquired for 30 mins. Prone scintimammography was performed one hour after administration of both tracers. ROIs were drawn on tumors and surrounding breast with the same technique in order to calculate the tumor to breast ratio (T/B). In addition, total body scan was performed one hour and three hours after 99mTc BN administration. All three patients underwent breast conserving surgery with lymphadenectomy. Postoperative pathologic assessment showed the following T and N stages in the three patients: T1bN0, T1c-N0, and T1cN1. RESULTS: All three cancers were imaged with both tracers. The T/B of 99mTc BN was always higher than that of 99mTc sestamibi. Chest uptake was always much higher with 99mTc sestamibi than with 99mTc BN. Comparison between 99mTc BN and 99mTc sestamibi images gave other intriguing results: in the N1 patient both tracers clearly imaged the invaded node, but on the 99mTc BM image the primary tumor was larger than on the 99mTc sestamibi image and the node was smaller. It is known that 99mTc BN is not taken up by vessels and inflammatory tissue. The time activity curves of the two tracers were significantly different in all patients, with an increase in 99mTc BN uptake in the first three to five minutes, followed by a less sharp uprise of the curve, quite similar to a plateau. CONCLUSIONS: Our first impression is that 99mTc BN is a useful breast cancer seeking agent and very promising for lymph node staging.

[Intermuscular and intramuscular lipomas of the neck].

Two cases of deep lipomas of the neck developed between the skeletal muscles were presented: one intermuscular and the other intramuscular. Taking into consideration the rarity of the case, the authors examined the clinical surgical aspect, paying special attention to the relationship between sonographic and computerized tomographic characteristics and the histological aspects in order to define whether the lipomatous tumors were benign or malignant. They also studied the localization of cervical lipomas, of lipoblastomas of hibernomas and of liposarcomas and defined an anatomo-clinical classification of both superficial and deep cervical lipomas.

['Incidentaloma' in inguinal hernia surgery].

Adult Granulosa-Cell Tumor (GCT) is an uncommon ovarian malignancy. The clinical course is characterized by slow growth with late recurrence. A variety of clinical and pathologic parameters have previously been evaluated for prognosis with inconclusive results. The aim of this study was to report a case of a granulosa-cell tumor of the ovary that recurred 25 years after first surgery. The clinical course and histopathology of the case were reviewed and a literature search for other reported cases was performed.

[Sigma's stenosis. Clinical, diagnostic and therapeutical problems].

Sigma's stenosis represent a frequent pathology, but its very difficult to have a pre-operatory diagnosis about the nature of these stenosis, not withstanding the introduction of more sophisticated instruments of diagnosis. In this work we present 9 cases of sigma stenosis; some of these with a common etiology and other very interesting for their rare and unusual origins. The patients were underwent to a different timing of diagnosis and therapy based on clinical history and diagnostic hypotheses; our experiences demonstrate that the clinical intuition is really useful for a correct diagnosis in the patients with a sigma's stenosis and consequently, in order to plan the correct therapy.

[Endometriosis. Report and clinical contributions].

The Authors, starting from the description of a clinical case of abdominal wall endometriosis, arisen subsequently to a caesarean section, take into consideration the world literature on the subject, and focus their attention on the problem of the anatomic location and the etiopathogenesis of the pathology.

[Nutritional and defunctionalized jejunostomy in the chemotherapeutic treatment of gastric non-Hodgkin's lymphoma. Preliminary experience].

The authors propose a jejunostomy on an omega loop distal to the Treitz ligament as a treatment for unresectable gastric lymphomas. The rationale is to provide nutritional support during chemotherapy in a situation when the stomach is defunctionalised. As assessed by clinical, morphological and biological parameters, the association of chemotherapy and jejunostomy may represent a valid therapeutical strategy for patients considered unresectable.

[Subtotal colectomy with ceco-rectal anastomosis].

A case of subtotal colectomy cecoproctostomy for multiple lesions of the colon is introduced. This procedure has advantages over ileoproctostomy because it spares the terminal ileum, ileocecal junction and cecum. Due to the high incidence of bowel movements after the ileoproctostomy operation, the authors recommend cecoproctostomy as a valid choice in a selectioned group of patients with multiple or extended lesions that spares cecum and rectum.

[A case of ileocecocolic intussusception from cecal carcinoma].

The authors present a case of ileocecocolic intussusception by carcinoma of the caecum. They stress the most peculiar aspects of this condition: rare etiology; complete invagination of caecum appendix and ileum; typical clinical presentation characterized by variable dimensions of the mass and symptoms not ascribing to occlusion, no lesions at endoscopy; evidence of a typical "target mass" visualized at T.C.

[Bilateral carcinoma of the breast: treatment and prevention, Review of the literature].

Authors analyze 256 patients admitted in III Clinica Chirurgica of University of Rome "La Sapienza" for breast cancer, from 1982 to 1992; 16 of them had later developed another neoplasm in the opposite breast. After a retrospective study of the clinical history of all patients they came to the conclusion that bilateral neoplasm frequency is similar to that reported in world literature (1-18%) (23, 9, 2). Moreover, are analyzed the primary risk factors for a bilateral carcinoma, and they consider the utility of the prophylactic surgical treatment of the opposite breast.

[The colorectal adenoma-carcinoma sequence: the limits between polypectomy and intestinal resection].

According to a clinic case, the authors pointed out the role of histological diagnosis in the therapeutic approach of large intestinal adenomas. In order to identify those lesions which can metastasize, having exceeded the muscularis mucosae and having invaded the submucosa, rigorous histological standards must be performed. Intestinal resection versus polypectomy is determined only according to the involvement or not of the muscularis mucosae.
