OBJECTIVES To identify factors that influence mortality in patients who are affected by intra-abdominal infections (IAIs) and to make a comparison among three different scoring systems: the Acute Physiology and Chronic Health Evaluation (APACHE) II score, the sepsis score of Elebute and Stoner, and the Mannheim peritonitis index. DESIGN Case series. (More)
This paper gives practical guidelines for diagnosis and treatment of chronic pancreatitis. Statements have been elaborated by working teams of experts, by searching for and analysing the literature, and submitted to a consensus process by using a Delphi modified procedure. The statements report recommendations on clinical and nutritional approach,(More)
Evaluation of prognostic factors of adenocarcinoma of Vater’s ampulla is still a matter of debate. The aim of this study was to evaluate retrospectively factors that influence early and long-term outcomes in a 20-year single-institution experience on ampullary carcinoma. A total of 94 consecutive patients with ampullary carcinoma or adenoma with severe(More)
To compare extensive with limited lymph node dissection in the surgical treatment of gastric cancer, 320 patients undergoing gastric resection during 1981-1990 were divided into two groups. Although patients undergoing extended lymphadenectomy (n = 157) had a longer operating time (P = 0.0001) and a greater intraoperative blood transfusion requirement (P =(More)
OBJECTIVE To evaluate whether the various surgical treatment reserved for ilioinguinal, iliohypogastric, and genital branch of the genitofemoral nerves, during open hernia mesh repair, is effective in reducing chronic postoperative pain. BACKGROUND Interest in chronic groin pain following herniorrhaphy has escalated, in recent years, due both to treatment(More)
AIM To identify risk factors related to pancreatic fistula in patients undergoing distal pancreatectomy (DP) and to determine the effectiveness of using a stapled and a sutured closed of pancreatic stump. METHODS Sixty-four patients underwent DP during a 10-year period. Information regarding diagnosis, operative details, and perioperative morbidity or(More)
HYPOTHESIS Despite aggressive approaches, locoregional tumor control and survival rates for patients with cancer of the pancreatic head remain disappointing. In the present study, we address whether intraoperative and adjuvant radiotherapy may improve the prognosis for these patients. DESIGN A retrospective study. SETTING University hospital. PATIENTS(More)
BACKGROUND/AIMS Few reports from the Western hemisphere have investigated the impact of pathological features and surgical modalities on the prognosis of patients affected by early gastric cancer (EGC). In particular, the extent of lymphadenectomy (limited vs. extended) and the type of gastric resection (subtotal vs. total) remain controversial issues in(More)
BACKGROUND Preoperative determination of Ki-67 expression, an important prognostic factor for grading nonfunctioning pancreatic endocrine tumors (NF-PETs), remains an important clinical challenge. OBJECTIVE To prospectively evaluate the feasibility, yield, and clinical impact of EUS-guided fine-needle tissue acquisition (EUS-FNTA) with a large-gauge(More)
The importance of pancreatic cancer staging is uncertain. The aim of this report was to evaluate the accuracy of combined standard imaging techniques in predicting the pathologic stage and to evaluate the prognostic effect of clinical staging to identify patient groups in which laparoscopy and laparotomy could be beneficial. Fifty-four patients were(More)
