[Gastrin-secreting neuroendocrine carcinoma: two cases identified and treated surgically with a radio-guided technique]. / Carcinoma neuroendocrino a secrezione gastrinica: due casi identificati e trattati chirurgicamente con tecnica radioguidata.

The authors present two cases of gastrin-producing carcinoma demonstrated by scintigraphy with In-111 pentetreotide. The possible malignant evolution of such tumours and the good results that can be achieved with surgical therapy suggest the usefulness of a radio-guided intraoperative strategy to locate the lesions and minimise invasive procedures. This approach enabled us to detect a lymph-node metastasis concealed in the adipose tissue in the first case and to exclude any other gastrin-producing tumour localisations in the second. We recommend that the radio-guided strategy should be included among the guidelines for the treatment of gastrinomas and believe that the procedure can also be used in other functioning endocrine tumours.

[Complicated diverticular disease of the right colon. Diagnostic and therapeutic difficulties: our experience]. / Malattia diverticolare complicata del colon destro. Difficoltà diagnostico-terapeutiche: nostra esperienza.

Right colon diverticulitis is an uncommon disease in Western countries. Often the disease is congenital and the clinical manifestations presenting at onset simulate the signs and symptoms typical of other diseases, such as acute appendicitis, appendicular abscess or caecal carcinoma. Since the diagnosis is usually intraoperative, diverticulectomy is recommended only in particular cases, with no complications resulting from inflammatory reactions. In the other cases, right hemicolectomy or segmental resection are the elective surgical treatments, depending on the patient's clinical condition and on the local anatomical situation. The authors describe 8 cases of complicated right colon diverticulitis, one of which with haemorrhagic complications, observed over the period from January 1999 to March 2003. The rareness and diagnostic and therapeutic difficulties of this disease are emphasised.
