Chemoradioimmunotherapy with 5-fluorouracil, cisplatin and interferon-α in pancreatic and periampullary cancer: Results of a feasibility study
2008
Abstract Background Recent studies give rise to the hypothesis, that adjuvant chemoradioimmunotherapy with 5-fluorouracil (5-FU), cisplatin and interferon-α (IFN-α) might be a possible new treatment of pancreatic cancer in resected patients. We report the up-to-now experience at our institution. Patients and methods Eleven patients with histological diagnosis of localized carcinoma of the pancreas ( n = 7) or periampullary ( n = 4) were prospectively analyzed. Four patients were deemed unresectable because of local invasion of adjacent organs (neoadjuvant setting) and seven patients underwent curative resection (adjuvant setting). Eight patients were classified as T3 carcinomas and three …
Recurrence of Acute Gallstone Pancreatitis and Relationship with Cholecystectomy or Endoscopic Sphincterotomy
2004
To determine the prevalence of recurrence of gallstone pancreatitis, its clinical features, and the presence of prognostic factors of recurrence.From January 1, 2000 to August 31, 2003, 233 patients admitted with acute gallstone pancreatitis (AGP) were prospectively studied. Patients were divided into two groups: recurrent and nonrecurrent group. Clinical, analytical, radiological, prognostic parameters, and severity (Atlanta criteria) were assessed, along with the performance of cholecystectomy or endoscopic sphincterotomy (ES). Clinical features of recurrence were analyzed. Univariate (chi(2), Student's t-test) and multivariate tests were performed. Statistical significance was assumed if…
Pancreatic insufficiency in celiac disease is not dependent on nutritional status
1994
To determine the relationship between pancreatic secretory capacity and nutritional status in celiac patients, we studied 52 patients with celiac disease (24 males, 28 females; age range 6-36 months) and 30 healthy control subjects (14 males, 16 females; age range 6-42 months). A secretin-cerulein test was performed on all patients, and levels of serum albumin and plasma fibronectin were assayed. In addition, weight/height ratios were calculated in the celiacs, who were then divided into three groups on this basis, as follows: celiacs with weight/height ratioor = 3rd percentile; those with weight/height ratio between the 4th and 10th percentiles; and those with weight/height ratio10th perce…
Surgical treatment of pancreatic cancer
1984
From 1964 to 1982, there were 782 patients treated for carcinoma of the pancreas. In 174 patients pancreaticoduodenal resection was possible (22%). Until 1977 we performed Whipple procedures, while from 1978 to 1982 total pancreatectomy was preferred. Comparing the results of both methods, we did not find any advantages of total pancreatectomy. Operative mortality did not decrease, survival time did not extend, and the higher resection rates (up to 26%) for more advanced tumor stages were accompanied by greater morbidity. With respect to the patients with inoperable cancer of the pancreas, we found over the last 5 years that the rate of those not undergoing surgery has climbed from 8% to 25…
Value of magnetic-resonance cholangio-pancreatography (MRCP) after unsuccessful endoscopic-retrograde cholangio-pancreatography (ERCP).
1997
Background and Study Aims: The present study tries to evaluate the success rate of MRCP when two attempts by experts to perform ERCP in a center failed. Patients and Methods: From March 1996 to December 1996 thirteen patients fulfilled the inclusion criteria. The MR cholangiopancreatograms were acquired using commercially available software in a clinical MR scanner (Magnetom Expert 1T-Scanner, Siemens, Erlangen, Germany). MRCP utilized heavily T2-weighted turbo-spin echo sequences with fat supression (HASTE). Maximum intensity projection (MIP) of the pancreatic duct and biliary tree was then carried out. Additionally, T1-weighted sequences were obtained using the breath-hold technique. Resu…
Elastase, myeloperoxidase, nitric oxide metabolites and oxidative status in subjects with clinical stable chronic renal failure on conservative treat…
2009
We evaluated, in a group of 41 CRF undialyzed subjects (29 men and 12 women, mean age 64.1 +/- 11.3 years), some parameters that reflect leukocyte activation (elastase, myeloperoxidase - MPO), plasma NO metabolites (NO(x)) and the oxidative status (lipid peroxidation expressed as thiobarbituric acid-reactive substances (TBARS) and total antioxidant status (TAS). Elastase was determined, on plasma separated from fasting venous blood, as elastase/alpha1-proteinase inhibitor complex. MPO was evaluated employing the Myeloperoxidase ELISA kit. The NO production was evaluated by a micromethod. The oxidation of polyunsaturated fatty acids was evaluated in plasma by detection of the thiobarbituric …
Endoscopic treatment of the "sump syndrome" after choledochoduodenostomy: a new technique using an amplatzer septal occluder.
2006
A 58-year-old male patient had been suffering for 35 years from recurrent cholangitis, biliary sludge and infection-induced stone formation after open cholecystectomy because of empyema of the gallbladder and severe acute and delayed postoperative complications. The pathophysiological origin of this chronic "sump syndrome" was a choledochoduodenostomy which had been performed prophylactically at the time of the initial operation. The patient agreed to an experimental treatment option with use of an Amplatzer atrial-septal defect (ASD) occluder for closure of the symptomatic choledochoduodenal fistula. The double-disc occluder was introduced through a 9 French diameter and 90 cm long sheath …
Imaging features of pancreatic metastases: A comparison with pancreatic ductal adenocarcinoma
2018
Purpose: To compare imaging features of pancreatic metastases (PM) with those of pancreatic ductal adenocarcinomas (PDAC). Methods: CT and MR scans of 24 patients with 54 PM and 30 patients with PDAC were reviewed to evaluate the imaging features, which were compared by using a Chi square test. Results: We found a statistically significant difference between PM and PDAC based on location (P < 0.001), margins (P < 0.001), arterial enhancement (P = 0.004), rim enhancement (P < 0.001), pancreatic duct dilatation (P = 0.01), common bile duct dilatation (P = 0.003), vascular involvement (P = 0.02), parenchymal atrophy (P < 0.001), peripancreatic fluid (P = 0.03). Conclusion: Imaging features mig…
Robotic-assisted pancreaticoduodenectomy with vascular resection. Description of the surgical technique and analysis of early outcomes
2019
Abstract Background Despite the potential benefits, the adoption of the minimally invasive surgery for the treatment of borderline resectable pancreatic cancer is still in the initial phase. We investigated the safety and feasibility of the robotic pancreaticoduodenectomy with venous resection/reconstruction (RPD SMV/PV). Methods Since March 2013 to October 2019, a total of 73 RPD and 10 RPD SMV/PV were performed. The two groups were case-matched according to the preoperative characteristics. Results Mean operative times and estimated blood loss were less in the RPD group in comparison to that in the RPD with SMV-PV group (525 vs 642 min, p = 0.003 and 290 vs 620 ml, p = 0.002, respectively…
ERCP and MRCP in the Differentiation of Pancreatic Tumors
2004
The introduction of endoscopic retrograde cholangiopancreatography (ERCP) in the early 1970s provided gastroenterologists with a number of diagnostic as well as therapeutic possibilities for examining biliopancreatic systems. In the meantime, magnetic resonance cholangiopancreatography presents a non-invasive alternative to diagnostic ECRP providing the advantage of a lower rate of possible complications. This article addresses the two methods presently available for differentiating pancreatic tumors. The objective of this article is to describe the advantages and disadvantages as well as the possibilities inherent in both methods.
