Current trends in chest wall malignant tumor.

Surgery used to treat chest wall sarcomas requires preoperative evaluation in order to document their margins, and to reveal any nodules of recurrence. Because of its considerable sensitivity and specificity ultrasound was associated with routine imaging techniques. The results obtained are useful in defining superficial and lateral tumor margins, but particularly in determining micro-nodules of recurrence which would otherwise go unrecognized. Based on the data obtained using routine methods of diagnosis and ultrasound, we submitted patients to excision that each and every time proved to be wide on histological examination. A particular surgical method was used for reconstruction, involving a polypropylene mesh fixed to one or two mouldable plates. This method exploits the elasticity of polypropylene, which is indispensable for the correct respiratory dynamics of the rib cage, thus avoiding paradoxical or harmful movement. Oncological and functional results were satisfactory.

[Stomach polyps. Clinical and therapeutic considerations].

The main clinical and therapeutic problems of gastric polyps are examined on the basis of 7 personal cases and the literature on the subject. 5 of the cases were adenomatous polyps proper, one of them in malignant degeneration and associated with polyposis of the large intestine. In 2 other cases, the histopathological picture revealed Peutz-Jeghers type hamartomatosis polyps confined to the gastric region without the typical cutaneo-mucous stigmata or familial character. Classification of polyps must allow not only for aetiopathogenetic or clinical criteria but for histopathological and histogenetic criteria also. A clear-cut distinction must be made between adenomatous polyps, of definite malignant potential, and pseudoneoplastic polypoid lesions that are essentially benign. The main diagnostic techniques available to handle a symptomatology that is often oligosymptomatic and aspecific, or associated with complications (such as ulcers, haemorrhage, stenosis or, not least, malignant transformation) are reviewed and stress laid on the importance of endoscopy prior to histopathological study which is of value only if carried out on a totally removed polypous lesion. The guidelines for indicating and selecting the radial surgical technique are presented.

[Diagnostic and therapeutic reflections on polyps and polyposis of the large intestine].

The systematic employment of pancolonoscopy in patients with diseases of the large intestine has shown that histological typing is essential when a polyp or polyposis is observed, since this is the only way prognosis can determined, and is only possible through endoscopic polypectomy. Familial investigation is also mandatory. If its findings are positive, every "polyp", irrespective of its number, site, and distribution, is a possible sign of polyposis. In this context, rectum preservation techniques are justified in relation to factors associated with both the polyp itself and its host.

[Surgical treatment of colo-rectal tumors. Immediate and long-term results in 1749 cases].

An assessment is made of the development of surgical techniques and results obtained throughout a series of 1748 cases of colon and rectum cancer observed over a period of 40 years. Attempts to improve survival have included an extension of lymph duct resection. This approach has proved successful, though a longer period of study is still needed. Lastly, rectal cancer is examined in terms of survival in function of various biological factors associated with the neoplasia.

[Congenital duodenal obstruction, Malrotation of the intestine associated with annular pancreas (author's transl)].

A newborn presenting duodenal stenosis by small bowel malrotation and annular pancreas is reported. Major diagnostic problems in duodenal obstruction of newborn are considered in keeping with literature review and personal experience. In this presentation clinical appearance has been long aspecific (apnea and bradycardia spells) in spite of a rather typical radiological picture. Really, the true diagnostic nature of midgut obstruction is often intraoperative. Face to any duodenal obstruction in a newborn the possibility of many malformations of the gut should be raised and consequently looked for accurately by the surgeon for a good postoperative prognosis. The surgical procedure of choice is frequently a duodeno-jejunostomy or a duodeno-duodenostomy; the annular pancreas should, on the contrary, never be sectioned.

The surgical treatment of spondylolisthesis.

The authors report the results obtained in 244 patients submitted to anterior interbody fusion. The method involves preoperative reduction in plaster (when necessary) and anterior surgical stabilization, facilitated by improvement in the anatomical and biomechanical conditions obtained with reduction. This method obtained excellent results in 85% of the cases, with fusion and absence of symptoms, and good results in 10% of the cases, with occasional symptoms and/or fibrous. Results were unsatisfactory in 5% of the cases because of residual radiculopathy (4 cases), non-union of the fusion (3 cases), retrograde ejaculation (2 cases), loosening of the graft (1 case) or unthreading of a screw (1 case). It is our opinion that anterior interbody fusion is the best surgical method for the stabilization of Meyerding grades III, IV and V spondylolisthesis. Posterolateral fusion is used to treat some cases with slippage equal to less than 25% (grade I) and cases where more than one level is involved.

[Non-metastatic osteosarcoma of the extremities: the pattern of relapse as a function of the type of treatment and of the modulation of the radiological follow-up of the thorax].

The authors analysed the patterns of recurrence of osteosarcoma of the extremities treated between 1959 and 1989 either with surgery alone (1959-71) or with combined surgery and adjuvant (1972-82) or neoadjuvant chemotherapy (1983-89). In a total of 452 patients with recurrent osteosarcoma, the initial site of metastasis was the lung in 88% of cases independently of the type of treatment received. The mean period of onset of pulmonary metastasis differed according to the type of treatment performed: 8 months for patients treated with surgery alone; 15.9 months for those treated with adjuvant chemotherapy and 20.3 months for patients treated with neoadjuvant chemotherapy. The incidence of metastases appearing within 12 months of FU was 87%, 56% and 21% respectively. In a most recent and effective neoadjuvant protocol (66% DFS), the incidence of recurrence owing to pulmonary metastasis during the first year of FU was 2% and as much as 75% of all recurrences were concentrated in the following 18 months. Surgery for pulmonary metastasis in patients undergoing chemotherapy was performed in 54 cases with secondary healing in 14 (26%). On the basis of these results the authors suggest a scheme of radiological follow-up for patients with osteosarcoma of the extremities treated with neoadjuvant chemotherapy with intensified controls (every 2 months) during the period with the highest risk of recurrence (13-20 months) and four-monthly controls during the first year and after 31 months of FU. In order to increase the efficacy of FU controls during the high-risk period, the a. propose using CT controls instead of chest X-rays at months 14, 20 and 26.

Associated lesions in multiple trauma of the pelvis. Diagnostic and therapeutic considerations.

On the basis of 80 cases of traumatic lesion of the pelvis with associated vascular and visceral lesions, observed between 1985 and 1994 at the Department of Surgery in Modena and at the Rizzoli Orthopaedic Institute in Bologna, the options for diagnosis as related to the specificity of lesions are examined, and the choices of indications and surgical technique are illustrated.

Neurologic deficit after resection of the sacrum.

The authors describe neurologic deficit (sensory, motor, and sphincteral) resulting from sacrifice of the sacral nerve roots removed during resection of the sacrum. The anatomical and functional bases of sphincteral continence and the amount of neurologic deficit are discussed based on level of sacral resection. A large review of the literature on the subject is reported and discussed. The authors emphasize how the neurophysiological bases of sphincteral continence (rectum and bladder) and of sexual ability are still not well known, and how the literature reveals disagreement on the subject. A score system is proposed to evaluate neurologic deficit. The clinical model of neurologic deficit caused by resection of the sacrum may be extended to an evaluation of post-traumatic deficit.
