Surgical management of ileosigmoid fistulas in Crohn's disease.

Radiologic and endoscopic demonstration of ileosigmoid fistulas is difficult: some are discovered only at operation. In these cases the surgeon is faced with the decision of either to remove "en bloc " the involved bowel or to simply close the sigmoid defect. Twelve patients with Crohn's disease complicated by ileosigmoid fistulas were operated: 7 by ileal and/or colonic resection and simple closure of the sigmoid fistula, 4 by double resection and 1 by total colectomy. Stomas were performed in 2. The review of this experience demonstrated that conservative surgery is effective and safe in most cases. Local extended resection should be reserved to cases where secondary involvement of a rather long segment of the intestine is present or where the sigmoid and rectum are primarily involved by active severe Crohn's disease. In these cases, a protective stoma may be considered.

Abdominal hydatid disease: US findings during medical treatment.

The sonographic appearance of 141 hepatic and abdominal hydatid cysts was studied in 63 patients undergoing therapy with benzoimidazolic compounds. The cysts were evaluated for size, margins of the cyst wall, and echo pattern of cyst contents to establish the response to the drugs. Changes seen on ultrasound (US) scans were classified as decrease in size, detachment of the cyst membrane, and appearance of echogenic material (matrix) in the cyst cavity. These findings, particularly the diffusely hyperechoic pattern, are explained on the basis of the action of the drugs. Twenty-one patients underwent surgery at the end of treatment. The US patterns of treated hydatid cysts are similar to those seen, though more rarely, in cases of spontaneous parasite involution in long-standing hydatidosis.

Sexual and bladder dysfunctions following surgery for rectal carcinoma.

A series of 475 patients who underwent surgery for rectal carcinoma were followed up and entered this study. Sexual and bladder function before and after surgery with respect to the surgical procedure was considered. 221 patients gave suitable information about their urinary function: bladder dysfunction was observed in 20% of amputated patients as against 13-14% of resected patients. 144 patients (103 males and 41 females) were available for a follow-up study of the sexual function. Sexual intercourse, libido, erection, ejaculation, dyspareunia, vaginal humidification, orgasm were the parameters examined. Almost all of them were more affected after abdominoperineal resection than after low anterior resection with manual or stapled anastomosis, although the difference was not always significant. In a few instances the rates were inverted. It is believed that these dysfunctions are not related to the type of surgery, but to required extent of radicality. Extreme care should be always taken when dissecting the end portion of the rectum to avoid injuries to the hypogastric plexus and the pudendal nerve.

Preoperative staging of rectal cancer: validity of the abdominopelvic angio-C.T.

The role of preoperative staging in the treatment of rectal cancer is emphasized. To this purpose, the use of abdominopelvic angio-C.T., which was carried out in 14 cases, is examined. Preoperative staging obtained by this method is compared with the postoperative one assessed by UYCC classification, modified by AYCC. Its diagnostic and prognostic role is evaluated in relation to the other methods. The validity of abdominopelvic angio-C.T. for a correct therapeutic approach is confirmed.

[Functional neurosurgery of cerebral palsy].

In 1983, approximately 40 000 patients in France and 5 760 patients in Switzerland suffered from cerebral palsy, representing more than 0.1% of their respective populations. The functional disability of these patients is particularly impressive and emphasizes the medical, social and economic importance of this problem. The term cerebral palsy is restricted to non-progressive disorders of motor function, already observed at an early age and due to cerebral lesions. These motor disorders can be of paretic, dystonic and dyskinetic nature. Their epidemiology, classification, etiology, pathology, early diagnosis and evolution are extensively reviewed by Th. Deonna. The difficulty in evaluation of treatment is the absence of a generally accepted rating scale. G. Broggi has proposed one on the basis of a large experience which could serve in the future for more objective evaluation. This monograph is devoted to the functional neurosurgical treatment of cerebral palsy. Physiotherapy and rehabilitation are part of the basic treatment of cerebral palsy, and must be continued after any neurosurgical treatment. Various conservative methods of treatment and their neurophysiological rationale are mentioned by P. Claverie. Some technical devices which improve the neurological deficits and facilitate rehabilitation are presented. Radiculotomies and neurotomies are probably the oldest neurosurgical operations for the treatment of spasticity. The neurophysiological and neuroanatomical basis of this therapeutic approach are treated in the review of the material from the neurosurgical department of Montpellier. Sixty cases were collected and the results analysed according to the type of operation (posterior radiculotomy, anterior radiculotomy, mixed) performed. Stereotactic thalamotomies and subthalamotomies are believed to be the best neurosurgical method to treat the tremor and improve other dyskinesias and hyperkinesias. The technique and a personal review of 49 cases of cerebral palsy are presented. The long-term follow-up in this study demonstrates that this type of operation markedly improves the functional disability of patients with moderate hyperkinesias, moderately improves patients severely affected, but also demonstrates that possible side effects cannot be ignored. Review of the literature indicates the difficulty in interpretation of results due to a lack of objective evaluation. Nevertheless, stereotactic thalamotomy can still be recommended when tremor and rigidity are the most prominent symptoms. Stereotactic dentatotomies in the treatment of spasticity were very popular 20 years ago, but have been largely forgotten for nearly a decade.(ABSTRACT TRUNCATED AT 400 WORDS)

Surgical treatment of liver metastases from colorectal cancer.

The experience with 28 patients undergoing hepatic resection for metastases from colorectal cancer is reported. In 15 cases the metastases were synchronous, in 13 metachronous, appearing 12 to 60 months after surgery of primary cancer. Six patients underwent right lobectomy, 2 left lobectomy, 9 left lateral segmentectomy, 6 right wedge resection and 2 bilateral wedge resection. In 20 cases the lesions were solitary, in 8 multiple. Overall operative mortality was 14.2%. Mean survival for synchronous metastases was 16 months with 3 patients living beyond 12 months, and 26 months for metachronous metastases with 4 patients living beyond 12 months. The obtained results are analyzed on the basis of staging of primary cancer, of the metastatic disease and type of resection, examining the morbidity and cause of long term mortality. It is evidenced that, even if correct pre- and intraoperative staging of metastatic disease is impossible, an aggressive surgical approach is the treatment of choice in surgically resectable liver metastases from colorectal cancer.

Long term results of stereotactic thalamotomy for cerebral palsy.

A group of 33 patients (between 10 and 30 years old and with average intelligence) underwent stereotactic surgery for abnormal movements due to cerebral palsy. Neurological, neurofunctional, and neuropsychological examinations were performed pre- and postoperatively. The length of follow-up ranged between 1 and 4 years. The clinical results are reported and discussed in relation to the targets, the side of the lesion, and the clinical picture. Our data show that better results are obtained in patients with tremor and hyperkinesias; dystonia is improved to a lesser extent, whereas spasticity tends to recur. Operation is more effective for patients with unilateral signs than for patients with bilateral symptoms. The clinical results are stable in time, and the side effects fade away after a few months.

Intraoperative high-resolution hepatosonography in the detection of occult metastases in colorectal carcinoma.

During surgery of colorectal cancer, real time B-mode high resolution ultrasound scanning was employed intraoperatively in 25 consecutive patients free of metastases at preoperative evaluation, to localize hepatic deposits. Results showed that intraoperative ultrasonography is a safe and simple technique providing the surgeon with accurate informations which may affect surgical technique as for -) extended indications for hepatic resection -) reduction of resections oncologically useless -) a more correct staging of resected colorectal cancer -) reduction of false positives at second look guided by CEA elevation.

Intraoperative high-resolution ultrasonography in the localization of occult endocrine pancreatic tumours.

Intraoperative pancraticosonography was employed in six patients to localize suspected endocrine tumours and to study the specific ultrasonic features. The cases included four insulinomas, one case of occult G-cell apudoma and one case of beta-cell microadenomatosis. Endocrine tumours are generally hypoechoeic and well defined with smooth borders. The study confirms that real-time operative high resolution sonography is a reliable technique to assist in the diagnosis of occult endocrine tumours and to guide the surgical approach.

Idiopathic dystonia: neuropharmacological study.

A total of 15 patients affected by idiopathic dystonia (7 with generalized and 8 with focal or segmental dystonia) were subjected to therapy with bromocriptine at low doses, pimozide and trihexyphenidyl. The symptoms were evaluated by giving a progressive score in relation to the intensity of the dystonic symptom to each of the body segments involved by the dystonia. Bromocriptine did not significantly modify the dystonia. Pimozide showed a slight nonsignificant improvement of the dystonic symptoms. Trihexyphenidyl was effective in the generalized dystonias, in agreement with previous reports in the literature. The variation in the pharmacological results could be due to the diversity of the dystonic syndromes, which comprise cases that are different in age at onset, site of dystonic symptoms, and evolution.

Depression after stereotactic thalamotomy in patients with abnormal movements.

A reversible depressive syndrome was found to be a very frequent side effect in a series of 33 patients subjected to stereotaxic surgery for the correction of abnormal movements. The depression was rated according to clinical and to Rorschach test parameters. The syndrome correlated significantly with age, depression being more frequent in adolescence, and with the side of the stereotaxic lesion, depression being more frequent after left thalamotomies in righthanded patients. The first correlation is of practical relevance, since it would clearly be wise to perform surgery before adolescence. The second correlation is of speculative interest in that is suggest a hemispheric asymmetry in the mood regulation processes. The incidence of this side effect in patients with abnormal movements may be further explained by the peculiar features of these patients, who need to be studied thoroughly before surgery.
