Surgical treatment of morbid obesity with biliopancreatic diversion and gastric banding: report on an 8-year experience involving 235 cases

2000

Abstract Study aim: Developments have recently been made in bariatric surgery outside the USA. The aim of this retrospective non-randomized study was to report on our experience regarding biliopancreatic diversion (BPD) and non-adjustable gastric banding (GB) in a population of 235 obese patients. Patients and methods: From March 1990 to March 1998, 235 obese patients were operated on, 142 by BDP and 93 by GB, via laparotomy after rigourous selection of the patient population. Results: The mean duration of surgery was 2 h 50 minutes for BPD and 1 h for GB. One postoperative death occurred due to massive pulmonary embolism. Early major complications were frequent in the BPD group ( n = 21) b…

Polymorphonuclear leukocyte membrane fluidity, at baseline and after in vitro activation, in obesity with or without diabetes mellitus

2002

We studied a group of 28 obese subjects (mean age 38.2+/-13.5 years, body mass index 35.0+/-5.6 kg/m2) with insulin resistance demonstrated employing an euglycemic hyperinsulinemic clamp, subdivided into a subgroup with normal glucose tolerance (NGT) and a subgroup with type 2 diabetes mellitus (DM). We examined the polymorphonuclear leukocyte (PMN) membrane fluidity at baseline and after activation with 4-phorbol 12-myristate 13-acetate (PMA) or N-formyl-methionyl-leucylphenylalanine (fMLP). At baseline, PMN membrane fluidity was significantly decreased in both subgroups compared to normals. In obese subjects with NGT no correlation was found between this PMN determinant and the parameters…

Pancreatic Endoscopic Sphincterotomy in Patients with Chronic Pancreatitis: A Single-Center Experience in 171 Consecutive Patients

2002

Background and Study Aims: In recent years, interest in endoscopic therapy techniques for pancreatic diseases has been constantly increasing. The aim of the present study was to assess the technical success, technique, and complications of endoscopic pancreatic sphincterotomy (EPS) in patients with chronic pancreatitis. Patients and Methods: A total of 171 patients with chronic pancreatitis and abdominal complaints were identified in whom at least one attempt at EPS was carried out. During the procedure, sphincterotomy was carried out using a guide-wire sphincterotome or a needle-knife papillotome. Patients were followed up after EPS for at least 24 h, including clinical symptoms and labora…

99mTc-Hexamethylpropylene Amineoxime Leukocyte Scintigraphy in Acute Pancreatitis: An Alternative to Contrast-Enhanced Computed Tomography?

2005

Contrast-enhanced computed tomography (CECT) is the most efficient imaging technique for the diagnosis and staging of acute pancreatitis (AP); its use, however, may be unfeasible in some patients as a consequence of the drawbacks of intravenous (IV) contrast material. The aim of this study was to test the utility of labeled leukocyte scintigraphy (LLS) as an alternative imaging technique to CECT for the staging of AP.Sixty-six patients with AP were prospectively studied. All patients underwent CECT and pancreatic LLS using (99m)Tc-hexamethylpropylene amineoxime as leukocyte label within a time interval of 2 days, in the early phase of AP. In addition, all patients had their serum C-reactive…

Long term follow up of patients with chronic pancreatitis and pancreatic stones treated with extracorporeal shock wave lithotripsy

1999

BACKGROUNDThere have been conflicting reports as to whether pancreatic ductal drainage achieved by endoscopy and lithotripsy improves the clinical outcome of patients with chronic pancreatitis.AIMSTo determine the clinical outcome in patients with chronic pancreatitis who received extracorporeal shock wave lithotripsy (ESWL), and were followed up for two to eight years.METHODSEighty patients with severe chronic pancreatitis and endoscopically unretrievable obstructive stones underwent ESWL with a piezoelectric lithotripter between 1989 and 1996. Clinical status, relief of symptoms, further endoscopic or surgical interventions, and mortality were defined.RESULTSForty three (54%) patients wer…

Liver transplantation for hepatic metastases of neuroendocrine pancreatic tumors: a survival-based analysis.

2011

Background. Liver transplantation (LT) has been accepted as a treatment in selected cases of neuroendocrine tumors (NETs) with hepatic metastases. Patients and Methods. A systematic review of the literature was conducted to evaluate long-term patient survival in the instances of LT for pancreatic NET. Univariate and multivariate regression analyses and survival analysis were performed. Results. Fifty-three clinical studies were screened. Data from 20 studies encompassing 89 transplanted patients were included in the study. Most primary tumors were endocrine pancreatic tumors (n = 69), with gastrinomas representing the most frequent diagnosis (n = 21). There were 61 functioning pancreatic NE…

Pancreatic cancer detection with magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography: a prospective contro…

2000

Summary Background Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive and increasingly used procedure in cases involving biliary and pancreatic diseases. However, the accuracy of MRCP in differential diagnosis between pancreatic cancer and chronic pancreatitis has never been documented in a large prospective controlled study. Methods 124 patients were recruited for the study, selected from 141 consecutive patients with an average age of 55 years (range 19–80) who presented to our department between February, 1996, and January, 1998, with a strong clinical suspicion of pancreatic cancer. MRCP images were interpreted by a radiologist and a gastroenterologist who were unaware…

Lysosomal aspartic and cysteine proteinases serum levels in patients with pancreatic cancer or pancreatitis

1997

Lysosomal cathepsins D (CD), B (CB), and L (CL) serum levels were determined by immunoassays in patients with chronic (CHP) or acute (AP) pancreatitis and in patients with ductal pancreatic carcinoma (DPC) and correlated with some biological and clinical parameters of this tumor. CB serum concentrations significantly higher than those measured in healthy subjects (NS) were observed in CHP, AP, and DPC patients (p < 0.01). However, no significant difference was noted among these groups. Increased CL serum levels were evident only in cancer patients compared to NS, AP, or CHP groups (p < 0.05), while no difference was observed among these groups. Elevated CD serum values were observed i…

Mucinous cystadenomas and intraductal papillary mucinous tumors of the pancreas in magnetic resonance cholangiopancreatography.

2000

Background and Study Aims: In mucin-producing tumors of the pancreas, diagnosis using endoscopic retrograde cholangiopancreatography (ERCP) is limited to cystic formations that communicate with the main pancreatic duct. Magnetic resonance cholangiopancreatography (MRCP) is a new, sophisticated method which is currently under evaluation. The authors describe the usefulness of MRCP in diagnosis of mucin-producing tumors. Patients and Methods: Six patients with mucin-producing tumors were investigated using MRCP and ERCP. Imaging was compared with surgery and histopathological examinations. Results: Three patients were found to have mucinous cystadenomas (MC), two patients had intraductal papi…
