[Cholelithiasis and diabetes].

The occurrence rate of diabetes was analyzed in 3370 consecutive patients admitted and surgically treated for biliary lithiasis at the I Department of Surgery-University of Rome "La Sapienza"-between 1959 and 1993. The incidence of such association was found to be overlapping with that of normal population. The natural history and the outcome of patients surgically treated for biliary lithiasis do not seem to be burdened by a concurrent diabetes. Diabetes was in turn found to be correlated with a more frequent presence of stones in the biliary tract. Possible causes of this correlation are discussed. The need in these patients of a more accurate diagnostic approach and specific therapeutic solutions is stressed.

[Mirizzi syndrome. Diagnostic and therapeutic considerations on 27 cases].

Mirizzi's syndrome is characterized by compression and/or stenosis of the common bile duct as a consequence of a stone impaction in the cystic duct or in the gallbladder neck. Clinical outcome, diagnostic pathway and operative management in 27 patients are presented. Ultrasound is referred as the first screening method, while E.R.C.P. and/or percutaneous transhepatic cholangiography allow to confirm the diagnosis. Surgical approach is considered to be of choice and technical expedients are suggested to prevent intraoperative damage and to repair defects of the common bile duct.

[Cancer of the distal pancreas: comments on its diagnosis and therapy].

The authors report 14 cases of neoplasms involving the pancreatic body and tail. Duration and characteristics of symptoms at outbreak, diagnostic work-up, resection rates, morbidity and operative mortality are statistically analysed and compared with those found in the same period in patients with cancer of the pancreatic head. A number of important differences between these two locations are detected and analytically discussed.

[The impact of technology on the diagnosis and treatment of pancreatic carcinoma].

Between 1960 and 1989, 207 patients with cancer of the head of the pancreas were diagnosed in the 1st Surgical Department of the University of Rome "La Sapienza". While in the first period (1960-'74) diagnosis was performed on the basis of clinical signs and traditional radiological findings, imaging and endoscopy became progressively the main diagnostic tools in the second one (1975-'89). The authors analyse how the different diagnostic approach has influenced the therapeutical outcome. Earlier diagnosis, increased resectability, proper surgical indication, decreased morbidity and mortality, improvement of survival are the achieved results.

[Leiomyosarcoma of the gallbladder: a clinical case].

A case of primary leiomyosarcoma of the gallbladder is reported together with a review of the literature. The nonspecific clinical picture of the disease and the consequent high frequency of misdiagnosis are stressed. Cholecystectomy combined with chemotherapy and radiotherapy is the treatment of choice suggested.

The impact of ultrasonography on the prognosis of pancreatic cancer.

The authors review 207 consecutive patients admitted for pancreatic cancer from 1960 to 1989 to the 1st Department of Surgery of the University of Rome "La Sapienza", in order to ascertain whether ultrasonography contributes to achieving the ideal goal of early diagnoses. The results achieved show a higher number of early diagnoses (< 1 month from first symptoms) performed by means of US, and a concurrent increase of cases amenable to radical surgery during the period 1975-1989, and basically from 1985 to 1989. Diagnostic imaging, namely US, is therefore deemed to provide earlier diagnoses and higher rates of pancreatic resectability.

A descriptive study of pregnant women with gallstones. Relation to dietary and social habits, education, physical activity, height, and weight.

Five hundred and twelve women attending the antenatal clinic of the Rotunda Hospital of Dublin were studied by means of abdominal real time ultrasound (US) scanning to establish some of the characteristics of those subjects found to be gallstone-positive, compared to the gallstone-negative control population. Coffee, tea and sucrose consumption, dietary fats, attendance at fast-food restaurants, education, cigarette smoking, alcohol, and physical activity did not show any substantial differences between the two groups, while there was a significantly higher prevalence of cholelithiasis in women who had been dieting and in overweight subjects.

A study of cholelithiasis during pregnancy and its relationship with age, parity, menarche, breast-feeding, dysmenorrhea, oral contraception and a maternal history of cholelithiasis.

We prospectively studied 512 consecutive women attending the antenatal clinic of the Rotunda Hospital of Dublin, Ireland, to assess the prevalence of gallstones among them and to describe the characteristics of those women found to be gallstone-positive (group 1), compared with the negative-control population (group 2). Real-time ultrasound scanning of the pelvic area was extended to the upper part of the abdomen. Cholelithiasis was detected in 23 patients. No substantial difference was found in parity of group 1 as compared with group 2. Also, early pregnancies, age at menarche and oral contraception did not have any significant difference between the two groups. However, we recorded a significantly higher prevalence of cholelithiasis in older women and in patients with dysmenorrhea. A positive trend was found in patients who had a history of previous breast-feeding and in women with a positive maternal history of symptomatic gallstones.

[Radical surgery and loco-regional chemotherapy in the treatment of liver metastases of stomach and colorectal cancer].

The results of surgical treatment of hepatic metastasis from stomach and colo-rectal cancer in a series of 28 patients have been assessed. 21 cases were subjected to hepatic resection (stomach cancer: 7 cases; colorectal: 14 cases) and 7 underwent locoregional chemotherapy through the gastroduodenal artery with fully implantable catheters (stomach ca.: 1 case; colorectal ca.: 6 cases). Of patients who underwent hepatic resection, 3 died postoperatively and 4 are still alive 5 years after the operation. Of the 7 patients treated with locoregional chemotherapy, 4 can be evaluated: 2 responded to treatment, 1 stabilised and 1 progressed. Clinically noteworthy toxicity was observed in one patient only.

[Embryologic and anatomo-surgical presuppositions in intraoperative injuries of the spleen. A clinical study].

Records related to 2559 patients submitted to main abdominal surgery have been reviewed. Accidental splenic injury and subsequent splenectomy occurred in 4.5% of cases. A study of the embryological development and anatomical patterns of the splenic peritoneum has been carried out as well as an analysis of the site and the shape of the capsular damage in order to assess the mechanism of injury. Avulsion of splenic capsule occurring from traction on the peritoneal attachment of the spleen appears to be the most common mechanism of injury. Previous surgery and geriatric age seem to be factors predisposing to splenic injury.
