[Selective use of intra-operative cholangiography in gallstone surgery]. FT L'impiego selettivo della colangiografia intraoperatoria nella chirurgia della calcolosi biliare.
No full textThe authors report their experience of the use of intraoperative cholangiography in 350 operations for biliary stones. The cholangiography was performed on all 52 patients with preoperative diagnosis of stones in CBD. In the 298 patients with gallbladder stones intraoperative colangiography was performed in 32 times, on the basis of previous jaundice, pancreatitis, microlithiasis, enlarged cystic duct or choledochus, and suspected palpatory reports of hepatic duodenal ligament. Intraoperative colangiography showed stones in all the patients of the first group and in 8 (25%) of the second. No patients reported disturbances attributable to residual stone with an average follow-up of 6 months
The surgical treatment of vascular and gastrointestinal implications in Behcet disease. Report of four cases
No full textThis study reports 4 cases of Behcet Syndrome which came under our observation and were surgically treated for vascular or gastrointestinal manifestations, These cases included 3 males and 1 female, mean age 26.5 years, of which 2 were treated with implantation of prosthesis for aneurysm of the abdominal aorta with recurrence of Behcet vasculitis and prosthesis substitution three years later in one case, I with total colectomy for ulcerous rectocolitis, while the last case (female) required excision and plastic reconstruction, for a perforated duodenal ulcer, Immediate and long-term results of the surgical treatment of the gastrointestinal and vascular manifestations and/or complications were satisfactory, whereas the long-term results of the medical treatment of the basic disease were unsuccessful in 50% of cases, BS is a rare affliction, whose pathogenesis is still poorly defined and in which the results of medical treatment cannot be regarded as satisfactory to date, Surgical treatment of its vascular and gastrointestinal manifestations and complications, on the other hand, was effective in our experience

An unusual complication resulting from surgical treatment of periampullary tumours
No full textBackground and methods. The authors describe the rising of four postoperative pancreatic pseudocysts in a series of 20 patients treated for periampullary tumours by pancreaticoduodenectomy (PDT), with the closure of pancreatic stump, between 1989-1996, The operation was always performed by the pylorus-preserving technique according to Traverso-Longmire. Results, In four patients (20%) 3, 4, 4, and 8 months after PDT with closure of the pancreatic stump, the authors observed the development of pseudocysts (PPC) in the pancreatic remnant. All these patients previously had a pancreatic fistula, Three symptomatic patients underwent surgical drainage of the pseudocyst in a jejunal loop (2) or in the stomach (1); in the asymptomatic patient, the clinical feature and the size of the cyst allowed for conservative treatment. In 2 cases PPC was the consequence of a pancreatic fistula evolved in acute pancreatitis of the stump. The PPC drained by cystogastrostomy appeared 4 months after the closure of the pancreatic fistula: the pancreatic stump was completely substituted by a cyst presenting a communication with the pancreatic duct, Conclusions. The authors conclude that PPC is a rare complication of the pancreatic resection that results from acute or chronic pancreatitis; sometimes pathogenesis is due to a cyst resulting from the pancreatic duct occlusion by phlogistic tissue as a consequence of the surgical suture
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Immunologic functions after laparoscopic cholecystectomy|Funzioni immunitarie dopo colecistectomia laparoscopica
No full textTrauma and surgical procedures can induce immune depression, related to the prevalent impairment of cell-mediated immunity, which may predispose to infections. The early recovery following laparoscopic cholecystectomy without infectious complications seems to be related to a lesser degree of surgical trauma and to only minimal impairment of immune functions. The present study was conducted in 20 patients with symptomatic gallstone disease, all undergoing laparoscopic cholecystectomy. Blood samples taken before operation and at 3 and 6 days postoperatively were tested for lymphocyte subsets (CD4+, CD8+, CD19+, CD57+), blood chemistry parameters (IgG, IgA, IgM, CH-50, C3, C4) and haemochrome. A group of 10 normal volunteers, matched for age and sex, were also examined twice at an interval of 48 h. Student's "t"-test was used for statistical comparisons. The findings showed only minimal changes in immune functions after operation (slight increase in CD57+ cells, and very slight decreases in IgM and C4 factor) and a slow reduction of serum haemoglobin levels as compared with preoperative values. All parameters returned to baseline levels within 6 days of the operation. This study demonstrates that laparoscopic cholecystectomy does not significantly affect immune functions, suggesting that immunity is preserved in the postoperative period
