[Surgical strategy in the treatment of adrenal cortex cancer. Expanded and repeated interventions]. / La strategia chirurgica nel trattamento del carcinoma cortico surrenalico. Gli interventi allargati ed iterativi.

AIM OF THE STUDY: To analyze our patients affected by adreno-cortical carcinoma (ACC) considering in particular the therapeutical approach in case of local recurrence or metastasis, and to compare our results with those from literature. PATIENTS AND METHODS: Since 1975 up to 2001, 35 patients with ACC were observed, 27 female and 8 male, aged between 3 and 76 year. All patients were surgically treated, 3 out of which laparoscopically. Thirty patients underwent radical and 5 palliative surgery. Twenty-two patients had extended resections to surrounding infiltrated organs, such as spleen, pancreatic taIl, vena cava, left colon and liver. The intervention was always completed by regional lymphadenectomy. Adjuvant treatment was administered in 17 patients, 4 out of which were re-operated. RESULTS: Only one patient died in the perioperative period for hyperacute adrenal failure. The survival rate was 85.7% at one year, 76.5% at two years, 70.8% at three and 28.3% at five years. Out of the 30 patients radically treated, only 3 are disease-free up to now. Local recurrence or metastatic disease was observed in 27 patients, out of which only 9 were eventually surgically treated, once or more times. All non-operated patients died between 1 and 6 months from the recurrence. The survival rate of the 9 re-operated patients was 51% at 2 years, and 22.1% at 5 years. Interestingly, one patient who has been re-operated three times, is still alive and disease-free after 7 years from the first recurrence. No significant difference was observed between Mitotane-treated and non-treated patients. CONCLUSIONS: According with data from literature, we conclude that surgical therapy of recurring local or metastatic ACC is up to now the best treatment, independently from the original stage of the disease. Controversies still remain about the utility of adjuvant chemotherapy in the primary and the recurrent disease.

[Laparoscopic approach to the "acute" and "chronic" bowel obstruction]. / Approccio laparoscopico alle occlusioni "acute" e "croniche" del piccolo intestino.

AIM OF THE STUDY: To retrospectively evaluate a series of patients with acute and chronic small bowel obstruction and discuss the indications of laparoscopic vs laparotomic approach and the outcome of both these techniques. PATIENTS AND METHOD: 85 patients with acute and chronic small bowel obstruction who underwent to either emergency or elective surgery since January 1999 up to October 2001 were enrolled. Subjects were divided into three groups: 39 treated with emergency laparotomy (group I), 13 with emergency laparoscopy (group II) and 33 with elective laparoscopy for chronic/subacute obstructions (group III). RESULTS: 1) the most frequent indication of the laparotomic approach was either multiple or major previous surgery as well as neoplastic diseases; 2) patients of the second group had frequently previous either minor or laparoscopic surgery; 3) the incidence of previous emergency surgery were maximum among the III group; 4) both post-operative ileus and mean hospital stay lasted less in the II than in the I group. The mean operative time and the morbidity was equal in the two groups; 5) we observed more intra-operative complications, a higher conversion rate and a longer both post-operative ileus and mean hospital stay in the II than in the III group. CONCLUSIONS: Our data support the role of laparoscopy in patients with chronic/subacute small bowel obstruction. Patients with acute obstruction may undergo laparoscopy after a careful selection, excluding subjects with previous either multiple or major surgery as well as neoplastic diseases. Such results need future confirmations from prospective randomized studies.

Laparoscopic adrenalectomy. Personal experience in 78 patients.

Laparoscopic adrenalectomy has proved to be the technique of choice for the treatment of benign pathologies of the adrenals and also for the treatment of isolated adrenal metastases, especially arising from lung tumor, but it shouldn't be performed for primitive adrenal carcinoma. The harmonic scalpel is very useful for laparoscopic adrenalectomy showing a significant reduction in operative time. The Authors retrospectively investigated 78 laparoscopic adrenalectomies performed from April 1995 to April 2000 using a transperitoneal approach with the patient on a lateral position as suggested by Gagner. Special care was taken to improve the surgical approach to the adrenals also by means of new technological devices as the Harmonic scalpel. The 78 laparoscopic adrenalectomies were performed in 70 cases for benign neoplasms: incidentalomas 24, Cushing's disease 16, Conn's disease 20, pheochromocytomas 9, myelolipoma 1. In the remaining 8 patients laparoscopic adrenalectomy was performed in 7 cases for isolated adrenal masses (5 metastases, 2 adenomas) in neoplastic patients, and in 1 patient for a preoperatively diagnosed adrenal carcinoma. Patients operated for functioning neoplasms had all remission or improvement of symptoms and humoral parameters; patients operated for isolated adrenal metastases showed this survival: 3 patients 3 years asymptomatic and disease free, 1 patient 18 months, and 3 patients are still alive and healthy after 6-12-15 months. A fast onset of local recurrence was seen in a patient operated for a preoperatively diagnosed adrenal carcinoma. We analyzed the operating time dividing the patients in three groups: a) 14 patients operated in the first semester of 1998 when we completed the training curve (average operative time 120.7 minutes); b) 14 patients operated from 1998-1999 (average operative time 118 minutes); c) the last 14 patients (operated from December 1999 to April 2000) where surgery was performed using the Harmonic scalpel (HS) (average operative time 94 minutes). The analysis of the average operative time comparing groups B and C using T-Student Test showed a significant reduction (p = 0.004). The morbility rate was 2.6%, mortality 1.3%, and a conversion rate of 2.6%. Laparoscopic approach results to be an extremely reliable procedure also for the treatment of incidentalomas up to 4-5 cm in which the incidence of adrenal carcinoma is about 13%. Doubts may yet result for the treatment of adrenal carcinomas preoperatively diagnosed. When laparoscopic adrenalectomy in performed using HS the operative time is significantly reduced and surgery is easier.

[The results of total thyroidectomy in Basedow's disease. The authors' personal experience of 180 cases]. / Risultati della tiroidectomia totale nel morbo di Basedow. Esperienza personale di 180 casi.

The therapeutic guidelines of Basedow (Graves') disease are based on three different approaches: medical treatment with anti-thyroid drugs, radio-iodine therapy and surgery. This choice has increasing consensus for the great improvement of the techniques, which at the moment are practically free of mortality risks, and have very low morbidity incidence, as well as for its positive influence on the course of the Graves' ophthalmopathy. For authors' study 180 patients affected with Graves disease, who have undergone total thyroidectomy, were retrospectively enrolled. The results show that hyperthyroidism symptoms are almost completely cured in most of the subjects, with a very low rate of complications as related to nervous (ricorrential) and parathyroid gland function. Furthermore, total thyroidectomy has resulted to have a positive impact in the clinical course of Graves' ophthalmopathy, particularly regarding some aspects of the eyes involvement, which have a dramatic effect in the "quo ad valitudinem" prognosis of these patients.
