[The biocompatibility of suture materials used in colon surgery. An experimental study in the rat].

Background: The aim of this experimental study was to compare the tissue behavior of biofragmentable anastomotic ring (BAR) with other synthetic materials used in colonic surgery.

Methods: Thirty-three rats were divided into four groups: group 1, sham-operated control animals without material implanted; group 2, with fragments of polypropylene monofilament implanted extraperitoneally in abdominal wound, between musculature and peritoneum; group 3, with metal clips implanted extraperitoneally in abdominal wound, between musculature and peritoneum and group 4, with fragments of biofragmentable anastomotic ring implanted extraperitoneally in abdominal wound, between musculature and peritoneum. Animals were sacrificed 30 days after the operation.

[The impact of conventional proctocolectomy on sexual function].

Seventy-one women who had a proctocolectomy for ulcerative colitis (n. 41) or Crohn's disease (n. 30) were interviewed in the follow-up clinic for gynaecological problems and fertility.

[Surgical therapy of recurrent varicocele].

In the surgical treatment of recidivous varicocele, has been adopted in eight patients a personal technique that varies in some points from the Ivanissevich's one. Large dissection and resection of the spermatic vein in peritoneum back zone for 6-8 cm. length, prier ligature of all possible collaterals.

[Diagnosis and therapy of splenic injuries].

The purpose of this work is a critical revision of spleen traumatism treatment. We have examined 46 patients which we treated by total splenectomy. We examined the recent literature on spleen functions and we tried to punctualize the newest methods for conservative treatment of the spleen.

[Experimental porto-systemic diversion in the rat: a comparative analysis of technics and results].

A number of techniques for performing portacaval end-to-side and side-to-side pancreaticoduodenal and mesenterico-caval shunts in rats are described. These shunts, transposition and arterialization are valuable objects for training in microvascular surgery. Effects of shunts, liver function, hemodynamics, metabolic and neurological changes related to portal flow, liver metabolism, and portal pressure are compared.

[Esophagogastroplasty in upper esophageal lesions. Apropos of 4 cases].

Oesophagogastroplasty has been performed in 4 patients in the Turin Department of Emergency Surgery. Three of them presented high neoplastic lesion of the oesophagus, while the fourth was suffering from mediastinic compression due to sclerosing mediastinitis. The technique and results are reported in detail.

[Radiological changes after mitral valvuloplasty].

The results of a radiological study carried out on a limited number of patients undergoing mitral valvuloplasty are reported. The good results achieved with this technique are confirmed objectively.
