Abstract
OBJECTIVE The aim of this study is to compare and to test the performance of all available risk scoring systems (RSSs) designed to predict long-term survival rate in asymptomatic candidate patients for carotid endarterectomy (CEA) for significant carotid artery stenosis. METHODS Data on asymptomatic patients who underwent CEA in three high-volume centers were prospectively recorded. Through literature research using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, six RSSs were identified for the intent of the study. Primary endpoints were 3- and 5-year survival rates after CEA. All items used as variables to compose multiple RSSs were applied to every patient in the study population. The 3- and 5-year mortality prediction rates for each score were assessed by sensitivity, specificity, and predictive negative and positive value calculation, as well as univariable Cox proportional hazard models with the Harrell C index. RESULTS During the study period, 825 CEAs in 825 asymptomatic patients were analyzed. All items used in RSSs were available in the dataset, with some concerns regarding their definition and application among RSSs. The 3- and 5-year survival rates of the study cohort were 94.5% and 90.3%, respectively. Among the six RSSs analyzed, no RSS demonstrated optimal results in terms of mortality rate prediction accuracy, although some scores had good diagnostic and risk of death precision. CONCLUSIONS RSSs, when used alone, fail to optimally detect postoperative life expectancy in asymptomatic CEA patient candidates. Further prospective controlled studies are needed to compose and validate RSSs with better calibration to predict outcomes.

Abstract
Carotid surgery variably modifies carotid afferent innervation, thus affecting arterial baroreceptor sensitivity. Low arterial baroreflex sensitivity is a well-known independent risk factor for cardiovascular diseases. The aim of this study was to assess the 4-mo effects of carotid endarterectomy (CEA) on arterial baroreceptor sensitivity and cardiovascular autonomic profile in patients with unilateral carotid stenosis. We enrolled 20 patients (72 ± 8 yr) with unilateral >70% carotid stenosis. ECG, beat-by-beat blood pressure, and respiration were continuously recorded before and 126 ± 9 days after CEA, at rest and during a 75° head-up tilt. Both pharmacological (modified Oxford technique, BRS) and spontaneous (index α, spectral analysis) arterial baroreflex sensitivity were assessed. Cardiovascular autonomic profile was evaluated by plasma catecholamines and spectral indexes of cardiac sympathovagal modulation [low-frequency R-R interval (LFRR), low frequency-to high frequency ratio (LF/HF), high-frequency R-R interval (HFRR)] and sympathetic vasomotor control [low-frequency systolic arterial pressure (LFSAP)] obtained from heart rate and SAP variability. After CEA, both the index α and BRS were higher (P < 0.02) at rest. SAP variance decreased both at rest and during tilt (P < 0.02). Before surgery, tilt did not modify the autonomic profile compared with baseline. After CEA, tilt increased LF/HF and LFSAP and reduced HFRR compared with rest (P < 0.02). Four months after CEA was performed, arterial baroreflex sensitivity was enhanced. Accordingly, the patients' autonomic profile had shifted toward reduced cardiac and vascular sympathetic activation and enhanced cardiac vagal activity. The capability to increase cardiovascular sympathetic activation in response to orthostasis was restored. Baroreceptor sensitivity improvement might play an additional role in the more favorable outcome observed in patients after carotid surgery.

Abstract
BACKGROUND/AIMS Strictureplasty (SP) or miniresective 'bowel-sparing' techniques (MR) can prevent the risk of intestinal stomia and short bowel syndrome in patients affected by Crohn's disease (CD). The aim of this study was to analyze the perioperative morbidity and mortality in 104 of 138 consecutive patients treated for CD complications using bowel-sparing techniques. We also considered the factors that may be related to the risk of perioperative complications and the long-term outcome. METHODS One hundred and four patients were treated with SP and/or MR and then included in a prospectively maintained database. The factors claimed to influence perioperative complications were analyzed using Fisher's exact test for categorical observations and the Mann-Whitney U test for continuous variables. A multivariate analysis, using logistic regression, and a long-term time-to-event analysis using the Kaplan-Meier function, were also performed. RESULTS Perioperative mortality was nil. In relation to the 6 postoperative complications (5.8%), 4 patients underwent minimal bowel resection (MR), 1 a MR with SP, and 1 SP alone. Three of these patients (2.9%) needed reoperation for septic complications, and 3 (2.9%) were treated as outpatients for enterocutaneous fistulas. A correlation (p < 0.05) was found between low serum hemoglobin levels and postoperative complications at univariate and multivariate analyses. The 5-year surgical recurrence-free rate was 75% overall, 73% for patients treated with SP, 78% with MR, and 77% with MR + SP. CONCLUSIONS Postoperative complications are not related to conservative or miniresective surgery even when active disease is present at the resection margins or the site of SP. The higher risk reported for patients with low serum hemoglobin and hematocrit levels suggests that surgeons should consider using preoperative iron and vitamin support, parenteral nutrition and erythropoietin therapy, when necessary, in those cases. Our postoperative morbidity, mortality and long-term surgical recurrence rate results support the efficacy and safety of SP and MR surgery in the treatment of complicated CD.

Abstract
Transcatheter arterial chemoembolization (TAE) is often considered a mean of palliation for inoperable liver carcinomas. A few centers use a sequential treatment (TAE followed by surgery). However the role of TAE in bringing to surgery patients with hepatocarcinomas (HCC) considered inoperable at first diagnosis is debated. We report on the case of a 57 y.o. male diagnosed as having HCC, inoperable because of bilateral location and size. The patient was treated with repeated TAEs and the results were monitored with CT scans. After three TAEs, the main tumor mass volume was reduced 2.2 fold and the patient could undergo surgery; the postoperative period was uneventful, with no clinical signs of liver failure. Our experience leads us to suggest that TAE, further to being an option for palliation, can be a valuable tool to lead to surgery otherwise inoperable HCC patients.

Abstract
BACKGROUND/AIMS Carcinoma of the head of the pancreas is reported with increasing incidence. The classical Whipple procedure, modified by Traverso and Longmire, is a major surgical undertaking and there is question on its indication in the case of lesions which, although technically resectable, are not susceptible to cure. PATIENTS AND METHODS We review 67 cases of carcinoma of the head of the pancreas comparing the results of radical vs. palliative surgery. The results were then compared with 27 additional cases of periampullary carcinomas. RESULTS Long term survival was obviously higher after resection, due to the more advanced tumor stage in the palliation group. However, perioperative mortality, supposedly high in extensive resective surgery, was 8.7% (vs 11.9% in the palliation group). CONCLUSIONS At present, extensive resective surgery carries unacceptable incidence of perioperative mortality. Therefore we suggest that indication for resection should be widened, as it may offer better chances of cure in resectable periampullary carcinomas and, even in non curable cases, it offers better quality of life and the advantages of tumor debulking.

Abstract
BACKGROUND/AIMS Cholangiocarcinoma of the hepatic hilum is a seldom curable lesion when detected and several methods of palliation have been suggested. Bismuth has proposed an intrahepatic cholangiojejunostomy on the third segment of the liver, which in his experience obtains effective biliary drainage with better quality of life compared with other forms of palliation. PATIENTS AND MATERIALS We have used this technique in nine cases. We evaluate results, mortality and morbidity, in comparison with other authors' reported series. RESULTS In the early postoperative period one patient died, two patients suffered from immediate postoperative complications, and jaundice resolved completely in six patients. Long term survival was influenced by the underlying disease. CONCLUSION Our findings support Bismuth preference for this technique of surgical palliation for non resectable tumors of the biliary tract.

Abstract
In the period 1968-1993, we treated 399 patients for colo-rectal cancer. Up to 1980, preceding large scale use of endoscopy, 217 patients, out of the group of 399, were submitted to surgery; at time of diagnosis all patients had symptoms of advanced colonic tumor (intestinal obstruction; palpable mass; significant rectal bleeding); none of the lesions detected was in Dukes A or B1 groups; 56 patients were in Dukes B2 and stages C1 + C2 + D were detected in 161 cases. In period 1981-1993 we treated 182 patients; in all cases the diagnosis consisted of endoscopical examinations. Out of this group 69 patients underwent endoscopic resection of polyps with focal neoplastic degeneration: 44 did not require surgery according to Haggitt criteria. In the group of 138 patients who underwent surgery, 89 were in Dukes A + B1 + B2 groups and 49 were in Dukes C1 + C2 + D groups. In our experience endoscopy is not essential in the clear cut colonic neoplasms, however it is an invaluable screening test in early stages, in poor symptomatic population, in elderly patients (> 50 y.o.) and in patients with non specific symptoms. We wish to emphasize how endoscopy has improved the results of colonic cancer surgery.

Abstract
The authors, in the period from Jan. 1980 to Dec. 1990, observed 67 patients with tumor located in the head of pancreas and 27 patient with periampullary tumors. These included 18 tumors originated from the ampulla of Vater and 9 from distal common bile duct. Operability rate ranged from 62.6% pancreatic carcinoma to 94.4% tumors of ampulla, according to the tumor location. Resectability rate ranged from 9.5% for pancreatic adenocarcinoma for 94.1% to ampullary tumors. Considering 23 resections, 18 were pancreatoduodenectomies and 5 local excisions for tumor of ampulla. Mortality was 7.7% after non resectional treatment and two patients (8.7%) died in the immediate postoperative period after radical resection. Multivariate analysis on all patients operated (n. 65) revealed that 5 years survival rate was significantly related to intent of operation (palliative = 0 - curative = 8.6%), histologic type, and site. In fact no patient with pancreatic adenocarcinoma achieved a 5 years survival rate. Two patients with adenocarcinoma of ampulla survived 5 years. Cancer of the head of pancreas is quite malignant because, owing to pancreas position, an early diagnosis is very hard. Most times resective surgical treatment is impossible because of the cancer diffusion.

Abstract
Of 431 patients with gastric cancer observed in our Istitution, 23 (5.3 %) had early gastric cancer (EGC). Macroscopic presentation, histology, depth of invasion, and lymph node involvement were evaluated in all the cases. All patients underwent surgery and an intensive follow-up was performed. Five of the 23 patients progressed, and the risk factors were examined. Histology seemed to be the main prognostic factor in our study, since intestinal type of EGC was associated to a significantly better prognosis. Total gastrectomy is indicated in the proximal localization of EGC, and should perhaps be performed also in cases presenting undifferentiated histology.

Abstract
We present 20 cases of primary non-Hodgkin lymphoma of the stomach. Histological classification, staging, age of patients and therapeutical approach were evaluated. Median overall survival was 30 months, and 5-year survival was 44%. In our small series, the age of the patients plays an important role: median overall survival is 18 months in patients greater than 60 y.o. (compared to 90 months in patients less than 60 y.o.) and 5-year survival 12.5% (compared to 62%).

Abstract
The authors report their experience with 10 cases of primary gastric lymphoma observed in 10 years. Nonspecific symptomatology and bioptic features often misleading to benign lesions (pseudolymphoma) explain why an early diagnosis is difficult to achieve. A correct surgical treatment, with careful pre- and intraoperative staging, associated to pre- and postoperative chemo- and radiotherapy, allows good results in terms of survival.
