[Familial adenomatous polyposis. Problems encountered with rectum preservation in surgical treatment and life expectancy].

Familial adenomatous polyposis is a genetically inherited disease with very high risk of colorectal cancer and with a large expression of multiple extracolonic malignancies. In recent years two surgical options are available for the treatment of FAP: total colectomy with ileorectal anastomosis and restorative proctocolectomy with ileoanal reservoir. The preservation of the rectum offers good quality of life and good functional results, but needs an accurate surveillance of the rectal stump and screening for the development of cancer.

[Massive hemorrhage caused by colonic diverticulosis].

Massive hemorrhage from diverticular disease of the colon is a very difficult problem in abdominal emergency surgery. The pathogenesis of bleeding colonic diverticulosis is strictly correlated to the angioarchitecture of the colonic diverticular wall. Here the vasa recta penetrate the colonic wall from the serosa to the submucosa through connective tissue septa.

[Large abdominal incisional hernias, use of prosthesis. Our experience].

Retrospective analysis of risk-factors in 241 patients with large abdominal incisional hernia collected in a 16-year period at the Department of Surgery, University of Pavia, allows the Authors to identify the aetiological mechanism of herniation and to discuss the fundamental technical skills in wall reconstruction. The recurrence rate after primary repair was 30% (63/209 patients). In 32 patients (13.

[Primary malignant neoplasms of the liver. Contribution of echography to the preoperative diagnosis].

Primary malignant hepatic tumors are relatively common and the possibility of radical surgical treatment in the initial stages has modified our clinical approach therefore stressing the validity of a correct screening and follow-up of this pathology. The Authors present their clinical experience in the field enriched by the use of ultrasonography and conclude that this represents a highly effective diagnostic technique whereas it is less reliable in the determination of the nature of the lesion.

[Postoperative external biliary fistulas: personal case series].

Over the period 1974-1986, five patients with external biliary fistulas were admitted to our clinic. The fistulas set in as complications of surgical operations due in 3 cases to a Kehr drainage of the common bile duct, in 1 case to drainage of a subhepatic abscess and in 1 case to pancreatic hydatid cyst. The causes of onset of the fistulas are reported as well as the therapy adopted in each case.

Efficacy and tolerance of ceftazidime in the treatment of post-operative respiratory tract infections.

Ceftazidime proved particularly effective in the treatment of acute respiratory tract infections arising in the immediate post-operative period, affording complete clinical cures in 88.8% of cases and a substantial improvement in the pathological picture in the other 11.2% of cases treated.

Study of the ATPasic lymphocytic activity in the woman at the end of fertile age.

The object we propose to ourselves is to define mean values of ATPasic lymphocytic activity in different physiological conditions. This study considers the ATPasic lymphocytic activity in the woman at the end of prolific age. The methodology we followed is Ellegaard and Dimitrov one of 1972 with some modifications and simplifications; the proteins dosage in the overfloating has been effected with biuret method.

Study on the ATPasic lymphocytic activity during menstrual cycle.

We previously studied ATPasic activity in the lymphocyte according to sex, age and in pregnant women. Now we considered it is interesting to go on with out study with the dosage of ATPasic lymphocytic activity during menstrual cycle, monitored with basal temperature method. The methodology we followed is Ellegaard and Dimitrov one of 1972, with modifications and simplifications while the proteins dosage in the supernatant has been effected with biuret method.
