The Authors report some observations on gallbladder calcification with the presentation of two clinical cases. The pathologic anatomy and the clinical aspects of this infrequent affection are described. The Authors underline the importance of surgical treatment, considering the frequency of carcinoma in porcelain gallbladder.
117 cases of spontaneous pneumothorax are reviewed. The authors report their experience and consider surgical drain to be the best method in most cases to achieve a rapid recovery. Surgical management or conservative approach can also to be used in selected patients.

The Authors report a case of coeliac axis atheromatous obstruction, with superior mesenteric artery steal. The coeliac axis, stopped up the origin was indirectly revascularized by hepatic artery. The early diagnosis of chronic intestinal ischaemia should avoid the intestinal infarction. The development of intravenous digital angiography will certainly help an early diagnosis.
34 patients admitted for suspected acute cholecystitis were evaluated using 99mTc IDA cholescintigraphy. The results of these studies are reviewed and compared with other diagnostic tests and the subsequent clinical diagnosis. Cholescintigraphy proved to be a safe, simple, highly accurate and sensitive technique. Therefore, 99mTc-IDA cholescintigraphy is proposed as the initial procedure of choice in the evaluation of patients with suspected acute cholecystitis.
A case of emergency revascularisation of the hepatic artery for liver necrosis following its forced ligature during corpo-caudal pancreatectomy for cancer of the pancreas in referred. Necrosis protection mechanisms, namely higher portal flow, increase in O2 extraction and collateral circulation are analysed. The therapeutic aids for preventing this serious event are presented. It is considered that peripheral expansion of the hepatic artery thrombosis prevented the installation of a valid collateral circulation, although the hypothesis of a reduction in portal flow should not be ignored.

A case of full-thickness necrosis of the small bowel, and colon, which required partial resection of the jejunum and total resection of the ileum and colon is reported. The case gives the chance for a review of the Literature on intestinal necrosis not caused by vascular occlusion. Nonocclusive intestinal ischemia, acute neonatal necrotizing enterocolitis and adult necrotizing enterocolitis including the Pig-bel disease, common in Papua-New Guinea, are examined. Resemblances and differences in etiology, pathophysiology and clinical findings are discussed. The hypothesis that the process of "bacterial translocation" plays a central role in the pathogenesis of bowel infarction, representing therefore a possible link between infective and vascular mechanisms, is emphasized. Important suggestions on massive intestinal necrosis management are also reported.
