[Cystic dilatation of the biliary tract].

Cystic dilatation of the biliary tract is a rare disorder, more common in children, with a high morbidity and mortality rate. Death may follow one of the possible complications (recurrent cholangitis, biliary cirrhosis, cholangiocarcinoma). The Authors report the case of an asymptomatic adult woman. According to CT scan and ERCP the lesion found was classified as type IVb of Todani's classification. The cyst was removed and a Roux en-Y reconstruction was performed. This procedure is currently associated to a low mortality rate and the best long term results.

[Rare tumor of the stomach: leiomyoblastoma].

The Authors report a case of gastric leiomyoblastoma presenting a dyspeptic and painful symptomatology and microcytic hyposideremic anaemia. The patient underwent elsewhere gastric resection and was discharged with the diagnosis of "gastric leiomyoma characterized by bizarre cells". After a review of the literature, the Authors emphasize the anatomo-pathological and clinical aspects pointing out the diagnostic difficulties in this malignancy. The correct treatment is based on predicted factors of malignancy.

[Surgical treatment of obesity: our experience].

The surgical treatment of morbid obesity is reserved to patients non responding to medical and dietetical therapy. The Authors suggest for these patients a sequential surgical treatment: a vertical gastroplasty, followed by an abdominoplasty. In the Authors experience, this approach offers good results in terms of weight loss and aesthetics. In this paper, the results obtained in 19 patients, operated for morbid obesity in the past three years, are reported.

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.

Pathophysiological patterns of hepaticojejunostomy. Scintigraphic evaluation.

Results obtained using 99mTc HIDA in the follow-up of 17 patients who underwent hepaticojejunal bypass for different indications are examined. Results are also compared to other commonly used procedures such as echography and cholangiography (I.V. or PTC). Preliminary results appear to confirm that cholescintigraphy is an accurate procedure which allows an anterograde and physiologic visualization of the anastomosis.
