This paper is a critical review of the clinical records of 20 patients who underwent a Transduodenal Sphincteroplasty (PSP), from October 1990 to January 1992 at our Department (General Surgery). The age was 64.9 (14.2) years (mean and standard deviation), but 14 (70%) of those patients were older than 60 (range: 63 to 89) and 9 (45%) were in the 8th up to 9th decade of their lives. In 16 patients PSP was performed at the same time as cholecystectomy. Common bile duct (CBD) exploration was decided in 11 patients only on the basis of the intraoperative cholangiographic findings (evidence of CBD stones and/or benign stenosis of the Papilla of Vater) as demonstration of the permanent role of this examination in biliary surgery. Among the patients who underwent PSP some time after cholecystectomy, one had a lesion of the choledochus, sustained when he was cholecystectomized 15 days before. Because of the fact that recovery was prompt and definitely uneventful, PSP together with the infusion of somatostatin (SMTN) can be considered a useful approach to the treatment of the biliary fistula.

This paper describes the clinical course of a 76-year-old woman surgically treated in our department (General Surgery) for obstructive jaundice in Mirizzi syndrome (II). Ultrasonography and ERCP failed to demonstrate the pathological situation at the level of the biliary tree. When laparotomy was decided because of the progressive worsening of the general clinical conditions of the patient, intraoperative cholangiography showed the presence of a cholecystocholedochal fistula with multiple residual stones eroded into the common bile duct. Surgical management consisted of partial cholecystectomy, removal of the stones, choledochoplasty and exploration of the distal part of the common bile duct by a transduodenal sphincteroplasty. The post-operative period was uneventful and the patient was discharged from our department nine days after surgery. Even though the surgical approach to Mirizzi syndrome generally includes procedures other than papillosphincteroplasty+partial cholecystectomy, our experience seems to substantiate the efficacy of the previously mentioned treatment under suitable conditions.

Abdominal aortic aneurysm (AAA) repair associated with a pelvic kidney is extremely rare. To date only 14 cases have been reported in the literature. The main problem during aortic cross clamping is kidney preservation. The purpose of this article is to record and additional case of AAA repair associated with a native pelvic kidney. The preservation has been successfully achieved by a distal aortic double clamping.

Present knowledge of hepatic trophism and regeneration after partial resection of the parenchyma is reviewed. The importance of the various factors influencing hepatic regeneration (so-called hepatotrophic factors) is stressed by examining the most interesting data reported in the literature. In particular, an attempt is made to classify such factors according to their origin (e.g. hepatic or extra-hepatic) and specificity of action. A brief discussion of the clinical implications of this research and current treatment for acute and chronic hepatic insufficiency, with particular reference to the latest surgical techniques, closes the paper.
