[Surgical treatment of parathyroid hyperplasia]. / Il trattamento chirurgico dell'iperplasia delle paratiroidi.

BACKGROUND: To review a series of 11 patients affected by hyperplasia of parathyroid glands and to discuss diagnostic and therapeutic tools. METHODS: A series of 11 patients out of 44 (= 25%) with primary hyperparathyroidism has been retrospectively reviewed. They underwent surgery in I surgical Department of OORR of Bergamo. All 11 patients were submitted to ultrasound and computed tomography examination before surgery, without any localisation of hyperplastic or adenomatous tissue. An exploring cervicotomy was performed with subtotal parathyroidectomy after the anatomopathological result of hyperplasia. RESULTS: No adverse effects related to surgery were observed. All patients could be considered as cured with a median follow-up of 36 months. CONCLUSIONS: Among hyperparathyroidism, hyperplasia is an underhand form and even if the laboratory diagnosis is simple, the imaging techniques cannot always localise the pathologic tissue. Personal experience shows the role of subtotal parathyroidectomy (removal of 3 parathyroid glands and a half of the last one) confirmed by the absence of adverse effects or relapse with a median follow-up of 36 months.

[Surgical treatment of liver trauma: our experience]. / Il trattamento chirurgico dei traumi epatici: nostra esperienza.

The Authors report their ten-year experience in the surgical treatment of liver injuries. Thirty-five patients underwent emergency laparotomy for hepatic trauma: 14 showed associated injuries, mostly of the spleen, while 21 had isolated liver lesions. Emergency surgical operation was performed for those patients with hypovolemic shock due to massive haemoperitoneum, while for all stabilized patients a preoperative ultrasonography or a computerized tomography was diagnostic. With a correct diagnosis, nowadays possible thanks to the overmentioned radiologic means, a group of patients was not treated by laparotomy, but strictly monitorized. For the patients who underwent laparotomy, good results with a low mortality rate were obtained using a surgical conservative treatment.

[Diagnostic findings and the surgical treatment of liver metastases: our experience]. / Orientamenti diagnostici e trattamento chirurgico delle metastasi epatiche: nostra esperienza.

The authors report their 10 year experience of 32 consecutive hepatic resections for metastases. All patients were preoperatively evaluated with US and CT, however, in 9 cases the diagnosis was obtained at laparotomy. In the first years there were no codified criteria for indications to surgery, while recently these were restricted, because of more favourable prognostic evaluations, to the metastases from colorectal carcinoma, endocrine or carcinoid tumours, digestive system neoplasms invading adjacent liver (in this case usually with palliative goal). The low mortality and morbidity registered explain the safety and efficacy of this procedure, also taking into account the fact that currently surgery is the only effective procedure with curative purpose. Criteria for patients selection, particularly in case of colorectal cancer, are referred and discussed and consequently prognostic factors are proposed: hepatic involvement extent, stage of primary tumour, absence of extrahepatic metastases, disease free interval between resection of primary tumour and hepatic resection for metachronous metastases.

[The diagnostic and therapeutic problems of endocrine tumors of the digestive system: our experience]. / Problematiche di diagnosi e terapia dei tumori endocrini dell'apparato digerente: la nostra esperienza.

The authors experience in the surgical treatment of endocrine tumours of the digestive tract is reported. Particularly, they emphasize that in spite of the several syndromes associated with these neoplasms, diagnostic and therapeutic concepts herein analyzed are similar.
