Colonic lesions in pancreatitis.
Lesions of the colon are generally considered to be uncommon sequelae of pancreatitis. They include: localized paralytic ileus (colon cut-off sign), necrosis, fistulae, stenosis and varices. On the basis of an extensive review of the literature (432 cases), it is suggested indeed that the real incidence is significant. The anatomic relationship of the large bowel to the pancreas is an important factor in the genesis and localization of the lesions. Enzymatic-inflammatory and ischemic processes are involved in the most highly supported theories. Colon cut-off sign is almost always spontaneously reversible and may represent an "alarm" for more serious complications. Massive necrosis develops during the early stage of severe pancreatitis and its mortality rate has been reported to be high. Fistulae are late complications of the disease, associated with a protracted course and probably a consequence of pancreatic suppuration or pseudocysts. Stenoses are the most interesting colonic complications following pancreatitis and caused by either acute obstruction of the colon due to an inflammatory mass or progressive obstruction due to pericolic fibrosis. In this case, the clinical picture may mimic carcinoma.

Severe hemorrhagic complications in pancreatitis.
Severe bleeding may complicate the course of either acute or chronic pancreatitis, the latter being more frequently involved. Pseudocysts, severe inflammation, regional necrosis and infection may cause major vessel erosion with or without pseudoaneurysm formation which eventually may result in severe bleeding into the gastrointestinal tract, retroperitoneum and peritoneal cavity. The AA report their experience on 8 cases and analyze the data of a comprehensive review of 389 cases of massive bleeding reported in the literature during the last 100 years until December 1993. Mortality rate seems to be related to the etiology of the bleeding along with its localization and the underlying anatomo-pathologic findings. In patients with chronic pancreatitis it is 22% while in patients with acute pancreatitis or chronic pancreatitis with acute exacerbation it is 60.4% and 57.1% respectively. Splenic, gastroduodenal and superior pancreaticoduodenal arteries are the most commonly involved vessels being associated respectively with a mortality rate of 20.5%, 27.9% and 46.1%. Massive haemorrhage complicating infected necrosis or abscesses implies a worse prognosis when compared to severe bleeding associated with pseudocyst with or without pseudoaneurysm. The increasing use of diagnostic and interventional radiology appears to be the way forward to improve survival rates. Awareness of high risk predisposing condition, activism in achieving an early identification of the bleeding sources, and eventually its angiographic control are essential guidelines for successful approach to the most unpredictable complication of pancreatitis. When embolization fails or is followed by recurrence of hemorrhage, definitive surgical procedures should be immediately instituted.

Is intraoperative ultrasonography useful in pancreatic cancer surgery?
Preoperative staging of pancreatic cancer represents a major challenge for a suitable surgical management of the disease. In a consistent number of patients laparotomy is still necessary in order to decide whether the tumor is resectable or not. In the present paper the Authors report their experience with intraoperative ultrasonography (IOU) in evaluating pancreatic cancer resectability. Very important data for intraoperative decision making were obtained in 37.9% of the patients, useful information in 31%, while in 31% IOU may be looked forward to as an important aid in decision making and for a safely guided dissection.

[Role of arteriography and percutaneous transluminal angioplasty in the diagnosis and treatment of arterial vasculogenic impotence].
High quality arteriographic studies of the iliopudendal vascular tree are mandatory for the correct examination of arteriogenic impotence patients before revascularization procedures. Twenty-three patients with chronic erectile dysfunctions due to stenosis or occlusive arteries diseases of the iliac arteries were treated with percutaneous transluminal angioplasty (PTA) in our Department. A positive clinical result was obtained in 15 of 23 cases (65.2%). The maneuver was successful in 8 of 14 patients with vascular lesions of the common and/or external iliac artery (57%). The erectile dysfunction was resolved in 4 of 6 patients with stenosis of the external iliac artery associated with a stenosis of the hypogastric artery (66.6%). The erectile dysfunction was also resolved in 3 patients with a single vascular lesion in the hypogastric artery. No major post-angioplasty complications were observed. PTA is a repeatable and not very invasive method with a low complication rate and could represent a valuable alternative to surgical revascularization in the patients with associated impotence and claudication of leg and hip. Moreover, it makes the treatment of choice in the patients with erectile dysfunctions due to isolated lesions of the hypogastric arteries.

[History of reconstruction following total gastrectomy].
Near a century after the first successful total gastrectomy for gastric cancer, the authors review the various technical proposals for digestive tract reconstruction following total gastrectomy. Following a classification based on duodenal circuit, on the viscerum employed and on the creation of pouches and/or anti-reflux mechanisms, pros and cons of the various classes of reconstructions are clearly depicted, suggesting the reasons that made Roux-en-Y esophago-jejunostomy and jejunal interposition the most used reconstructive procedure in worldwide clinical practice.

DNA ploidy, proliferative index and EGF-R status in 130 cases of resected gastric cancer--a multivariate analysis.
BACKGROUND/AIMS: The purpose of this study was to define the prognostic role of DNA ploidy, proliferative index and EGF-R status in resected gastric cancer. MATERIALS AND METHODS: Ten clinico-pathological parameters and three biological factors obtained from flow cytometry and immunohisto-chemistry were evaluated in a series of 130 gastric cancer patients who received surgical treatment, including 28 stage IV cases (21.6%), using paraffin-embedded and fresh specimens in 77.7% and 22.3% of the cases, respectively. These variables were first analyzed and tested for correlation within the whole series and then weighted against survival in 117 applicable cases through univariate and multivariate analyses. RESULTS: Aneuploidy was significantly related to higher proliferative activity, EGF-R expression and deeper stomach wall infiltration. Higher proliferative activity was significantly related to deeper stomach wall infiltration and larger tumor diameter. The latter showed a significant relationship to EGF-R expression. Univariate analysis showed the significant variables for survival to be DNA ploidy, pT, pN, M, stage, histological type according to Lauren and tumor diameter. Multivariate analysis calculated on these significant variables using the Cox multiple stepwise regression model detected three factors which independently influence survival: pathological stage (p < 0.00001), histological type according to Lauren (p < 0.002) and DNA ploidy (p < 0.03). CONCLUSIONS: DNA ploidy was shown to be a significant prognostic parameter in resected gastric cancer after pathological stage and histological type according to Lauren. The prognostic roles of proliferative activity and EGF-R status require further investigation.

[Palliative procedures in the treatment of non-resectable pancreatic tumors. Retrospective study of 294 cases and review of the literature].
At least two thirds of patients with pancreatic cancer are still unsuitable for resection, because of the extent of their disease or because of their high-risk conditions. In these cases, a palliative treatment is indicated to maximize the quality of life, in spite of the poor prognosis. During the years 1959-95, two-hundred-ninety-four patients, affected with pancreatic neoplasm, were observed. Resectability rate was 18%. One-hundred patients underwent surgical palliation (34%): 58 biliary-bypasses, 15 gastroenterostomies and 27 double-bypasses. Sixty-nine explorative laparotomies were performed (23.4%), of which thirty-six were carried out during the years 1959-70. Sixty-three patients did not undergo surgical treatment (21.6%), of which twenty-two underwent percutaneous biliary drainage, during the years 1981-95. Overall morbidity rate was 13% with decrease during the years of major postoperative complications. During the years 1959-70 operative mortality rate after surgical bypass was 13.6%, during 1971-80 was 10.5% and during 1981-95 decreased to 8.1%. Major percentages were reported after explorative laparotomies. During the years 1959-70 and 1971-80, operative mortality rate was 16.6%, compared with 9.5% during the years 1981-95. Patients with stage II tumours survived palliative surgery for about 12.8 months, compared with those with stage III and IV tumours, who survived for about 10.6 and 5 months, respectively. Patients who did not undergo surgical treatment survived 8.3, 4 and 1.3 months, respectively in II-III and IV stages. In this paper the authors examine advantages and disadvantages of palliative procedures, on the bases of their aims: relief of obstructive jaundice, duodenal obstruction and pain.

Lessons learned from a complicated case of cephalic obstructive chronic pancreatitis.
The authors report the complex case of a 51 year-old man admitted to his local hospital for gallbladder and common bile duct lithiasis, 1 year before admission to our hospital. There, he was treated by cholecystectomy and transduodenal biliary sphincteroplasty. He was readmitted after 3 months because of a painful episode and was discharged with the diagnosis of "relapsing acute pancreatitis in chronic pancreatitis." At our hospital, he underwent laparotomy and revision of the previous transduodenal biliary sphincteroplasty. Pancreatic sphincteroplasty and septectomy were also performed. The night after surgery, the patient suffered from acute post-operative pancreatitis complicated by severe hemorrhage due to erosion of the superior pancreaticoduodenal arteries, treated with gastroduodenal artery embolization by tungsten coils. Three months later, the patient suffered from another acute episode. An endoscopic retrograde colangio pancreatography (ERCP) showed the complete patency of the sphincteroplasties but clearly identified the persistence of a severe cephalic stricture. Therefore, the patient was readmitted to our hospital and underwent another laparotomy. A pylorus-preserving pancreaticoduodenectomy (PPPD) was performed. The post-operative course was uneventful and at 14 months follow-up the patient was in good health. The discussion focuses on the surgical treatment of chronic pancreatitis with cephalic Wirsung duct stenosis, stressing the increasing role of PPPD as a first-choice option.
