Gallstone ileus is an uncommon type of mechanical intestinal obstruction caused by an intraluminal gallstone, and preoperative diagnosis is difficult in the Emergency department. This study is a retrospective analysis of the clinical presentation of 5 patients with gallstone ileus treated between 2000-2010. Clinical features, diagnostic testing, and(More)
Bleeding from the site of a trocar insertion is a relatively frequent complication after laparoscopic surgery, despite precautionary techniques aimed at reducing such events. It may result in a hemoperitoneum, requiring emergency reintervention or large hematomas of the abdominal wall. In the latter case, although conservative treatment is possible,(More)
AIMS Recently it has been hypothesized that perforation of colorectal cancer (CRC) itself is not a predictor of poor prognosis. The aim of this study was to analyze the prognostic impact, of the spontaneous perforation of the tumour, metastatic lymph nodes and lymph node ratio (LNR) after potentially curative surgery. METHODS Retrospective analysis of(More)
UNLABELLED Technical failure in pancreas transplant has been the main cause of the loss of grafts. In the last few years, the number of complications has reduced, and therefore the proportion of this problem. OBJECTIVES The Spanish Pancreas Transplant Group wanted to analyze the current situation with regard to surgical complications and their severity.(More)
Dear Editor: Carcinoid tumors are slow-growing neoplasms derived from enterochromaffin cells or Kulchintsky cells being thus neuroendocrine in nature. They may arise anywhere in the gastrointestinal tract, in the bronchi, and occasionally elsewhere (ovary, central nervous system). Within the gastrointestinal tract, most carcinoid tumors arise in the small(More)
Methylenetetrahydrofolate reductase (MTHFR) plays a key role in folate metabolism, and folate is implicated in carcinogenesis due to its role in DNA methylation, repair and synthesis. The MTHFR C677T polymorphism is associated with decreased risk of CRC and increased sensitivity to 5-FU treatment. The present study addressed the relationship between this(More)
Colorectal tumor perforation is a life-threatening complication of this disease. However, little is known about the anatomopathological factors or pathophysiologic mechanisms involved. Pathological and immunohistochemical analysis of factors related with tumoral neo-angiogenesis, which could influence tumor perforation are assessed in this study. A(More)
